Design Like No One Is Patenting - How SparkFun Stays Ahead of the Pack - 0 views

  • Electronics supplier SparkFun designs dozens of products a year and they haven’t patented a single one. It’s worked out pretty well so far.
  • makes its living by shipping kits and components like bread boards, servo motors and Arduino parts to a mixture of students, hobbyists, and professionals making prototypes
  • the company has made its name is in a stable of its own custom parts and kits, the designs for which it gives away for free.

  • “We find that people will copy your design no matter what you do,” she says. “You might as well just play the game and go ahead and innovate. It’s fun, it keeps us on our toes.”
  • “The open source model just forces us to innovate,” says Boudreaux.
  • the open hardware model means that SparkFun’s existence depends not on any particular product, but on an ongoing relationship with customers that’s not too dissimilar to the loyalty commanded by a fashion house.
  • wolf of obsolescence is always at electronics’ door
  • don’t spend much time worrying about the copyists, they just keep releasing new looks
  • it’s about staying relevant and filling the needs of the community
  • SparkFun’s rapid turnover model is one that echoes the fashion industry.
  • keep their service exemplary
  • listening to their customers
  • developed a community of loyal users and fans
  • weekly new product posts
  • You can learn a lot about what a company cares about by looking at what they give away and what they protect.
  • SparkFun’s actual value is in the community of fans and loyal customers that keep coming back, and the expertise under its roof in servicing their needs.
  • Their catalog has about 2,500 items at any given time
  • SparkFun orders parts from 500 suppliers
  • 15 new products every week
  • hey retire products at a similar rate, due to either low sales, or obsolescence
  • Of the 2,500 items, about 400 are things designed internally.
  • To handle the pace of change, SparkFun needs to keep its inventory lean.
  • “We try to do small runs and order in small quantities. Especially something that’s going to be obsolete quickly.”
  • To help manage the demand, they use an in-house software system
  • along with inventory and CMS management, tries to predict demand for different components and ensure they get ordered with sufficient lead time to account for how long it takes to get there.
  • the innovation (revisions and new releases) here at SparkFun is organic and not planned,” says Boudreaux, “But we do a few things to make sure we are keeping up.”
  • monitors all costumer feedback from emails to the comment section that is present on every page of the company’s site. They also ensure that team members have time to tinker in the office, write tutorials, and visit hackerspaces and maker events. “For us, designing (and revising) widgets is the job.”
  • anyone in the company can suggest ideas and contribute designs.
  • ideas run through an internal process of design, review, prototyping, testing and release.
  • “They eat these products up, even if the products are not ready for the mainstream & educator community due to minimal documentation or stability.”
  • symbiotic relationship with these early adopters, where feedback helps SparkFun revised and improve products for use by the rest of the community
  • I don’t think they help much
  • The risk of this rate of change is that SparkFun can end up outpacing some of their customers.
  • “There’s balance in everything,” says Boudreaux, “Innovation does not necessarily need speed in order to create valuable change. Sometimes innovation works at a slower pace, but that does not mean it is any less valuable to those that benefit from it, and we are constantly balancing the needs of two very different customers.”
  • unprotected and unencumbered by patents
  • racing to get the latest, coolest things in the hands of its customers.
  • patents
  • “We have to be willing to kill ideas that don’t work, take a lot of tough criticism, and move fast. If we stay agile, we stay relevant.”
  • cost $30,000 to $50,000
  • USPTO is so backed up you’ll have to wait three to five years to even hear back on their decision.
  • how much does technology change in five years?
  • company’s blog where they’ve been documenting production and business practices for years.
  • they even want to open source Sparkle. “It’s a wild ride,” she says, “but a fun one for sure.”

The basic orientation of p2p theory towards societal reform: transforming civil society... - 1 views

  • under the ‘leadership’ of corporations and those members of our society who have access to capital.
  • Despite all democratic advances, the state forms have clearly been captured by private interests.
  • continuous interchange and dialogue of citizens as they determine their collective life
  • ...22 more annotations...
  • everything that needs to be made, has to be designed through collaborative innovation in the first place
  • in a capitalist system, ‘civil society’ is not directly productive of the goods and services that we need to survive, live and thrive
  • Both civil society and the notion of citizenship can be criticized for being insufficiently inclusionary, and therefore as ‘mechanisms of exclusion’.
  • democratically governed by all participants and stakeholders in such commons
    • Kurt Laitner
       
      hmm
  • infrastructures of collaboration, which are managed by a new type of ‘for-benefit associations’
  • consisting of shared depositories of knowledge, code and design; the communities of contributors and users of such commons
  • which are not derived or secondary from either the private or state forms.
  • civil society is the locus of the shared abundance of value creation, and the place for the continual dialogue regarding the necessities of common life.
  • democratically decide
    • Kurt Laitner
       
      ? our values need be expressed in every action within the matrix, not just when a 'vote' is held, in fact general democratic 'voting' should probably disappear
  • the ‘common good’ of society as a whole
    • Kurt Laitner
       
      there is no such thing
  • The difference is that the commons where the immaterial value is created are positioned in a field of abundance characteristic for non-rival or anti-rival goods; while the for-benefit associations are responsible for the sometimes contentious allocation of rival infrastructures.
    • Kurt Laitner
       
      !!!
  • Whereas the commons themselves are plurarchies based on permissionless contribution, forking and other rights guaranteeing the diversity of contributions and contributors; the for-benefit associations are democratically governed.
  • true reform of the private sector and the corporate form.
    • Kurt Laitner
       
      really?
  • Under conditions of peer production, design and innovation moves to commons-based communitiies, which lack the incentive for unsustainable design; products are inherently design for sustainability, and the production process itself is designed for openness and distribution.
  • Under conditions of the rule of capital, for-profit corporations are beholden to work for the interests of the shareholders. This format allows for the accumulation of capital, but also indirectly of political power, through the power of money to influence politics and politicians. For-profit corporations are part of a system of infinite growth and compound interest, must continuously compete with other corporations, and therefore, also minimize costs. For-profit corporations are designed to ignore negative environmental externalities by avoiding to pay the costs associated with them; and to ignore positive social externalities, also by avoiding to pay for them. In terms of sustainability, corporations practice planned obsolescence as a rule, because while the market is a scarcity allocation mechanism, capitalism itself is a scarcity maintenance and creation mechanism. Anti-sustainable practices are systemic and part of the DNA of the for-profit corporation.
  • designed to make the commoners and the commons themselves sustainable, by not ‘leaking’ surplus value to external shareholders
  • mission-oriented, community supportive, sustainability-oriented corporate forms, that operate in the marketplace but do not themselves reproduce capitalism.
  • surplus value stays within the commons, allows its autonomous social reproduction, and sustains the commoners
  • ethical mechanism that subsumes profit making under the social goal of strengthening the commons.
  • because commons and their communities are themselves specific, and do not automatically take into account the common good of society as a whole .
  • A Partner State functions center around enabling and empowering social production and abandons some of the paternalistic aspects of the welfare state by focusing on strengthening the possibilities of autonomy.
  • mobilization of social forces to obtain a new social contract

Open Source 3-D Printed Nutating Mixer - Appropedia, the sustainability wiki - 0 views

  •  
    "As the open source development of additive manufacturing has led to low-cost desktop three-dimensional (3-D) printing, a number of scientists throughout the world have begun to share digital designs of free and open source scientific hardware. Open source scientific hardware enables custom experimentation, laboratory control, rapid upgrading, transparent maintenance, and lower costs in general. To aid in this trend, this study describes the development, design, assembly, and operation of a 3-D printable open source desktop nutating mixer, which provides a fixed 20° platform tilt angle for a gentle three-dimensional (gyrating) agitation of chemical or biological samples (e.g., DNA or blood samples) without foam formation. The custom components for the nutating mixer are designed using open source FreeCAD software to enable customization. All of the non-readily available components can be fabricated with a low-cost RepRap 3-D printer using an open source software tool chain from common thermoplastics. All of the designs are open sourced and can be configured to add more functionality to the equipment in the future. It is relatively easy to assemble and is accessible to both the science education of younger students as well as state-of-the-art research laboratories. Overall, the open source nutating mixer can be fabricated with US$37 in parts, which is 1/10th of the cost of proprietary nutating mixers with similar capabilities. The open source nature of the device allow it to be easily repaired or upgraded with digital files, as well as to accommodate custom sample sizes and mixing velocities with minimal additional costs."

      This is about self-organization, putting in place bounderies and internal mechanisms to make the the system self-organize into something desirable.  You can see this from a game theory perspective - how to set a game which will drive a specific human behavior.

      Very similar to SENSORICA, an environment of entrepreneurs. The argument against this is that not everyone is a risk taker or has initiative. The answer to it is that not every role in the organization requires that.

  • The system is not made up of artifacts but rather an elegantly designed void. He says “I prefer to use the analogy of rescuing an endangered species from extinction, rather than engaging in an invasive breeding program the focus should be on the habitat that supports the species. Careful crafting of the habitat by identifying the influential factors; removing those that are detrimental, together with reinforcing those that are encouraging, the species will naturally re-establish itself. Crafting the habitat is what I mean by designing the void.”

  • It is essential that autonomy is combined with responsibility.
  • staff typically manage the whole work process from making sales, manufacture, accounts, to dispatch
  • they are also responsible for managing their own capitalization; a form of virtual ownership develops. Everything they need for their work, from office furniture to high-end machinery will appear on their individual balance sheet; or it will need to be bought in from somewhere else in the company on a pay-as-you go or lease basis. All aspects of the capital deployed in their activities must be accounted for and are therefore treated with the respect one accords one’s own property.

      So they have a value accounting system, like SENSORICA, where they log "uses" and "consumes".

  • The result is not simply a disparate set of individuals doing their own thing under the same roof. Together they benefit from an economy of scale as well as their combined resources to tackle large projects; they are an interconnected whole. They have in common a brand, which they jointly represent, and also a business management system (the Say-Do-Prove system) - consisting not only of system-wide boundaries but also proprietary business management software which helps each take care of the back-end accounting and administrative processing. The effect is a balance between freedom and constraint, individualism and social process.
  • embodiment of meaning
  • But culture is a much more personal phenomenon
  • Culture is like climate- it does not exist in and of itself- it cannot exist in a vacuum, it must exist within a medium.
  • underlying culture
  • Incompatibility between the presenting culture and the underlying one provide a great source of tension
  • The truth of course is that when tension builds to a critical level it takes just a small perturbation to burst the bubble and the hidden culture reveals itself powered by the considerable pent-up energy.

      SENSORICA had this problem of different cultures, and it caused the 2 crisis in 2014.

  • Consider again the idea that for the health of an endangered species; the conditions in their habitat must be just right. In business, the work environment can be considered analogous to this idea of habitat.
  • A healthy environment is one that provides a blank canvas; it should be invisible in that it allows culture to be expressed without taint
  • The over-arching, high-level obligations are applied to the organization via contractual and legal terms.
  • But it is these obligations that the traditional corporate model separates out into functions and then parcels off to distinct groups. The effect is that a clear sight of these ‘higher’ obligations by the people at the front-end is obstructed. The overall sense of responsibility is not transmitted but gets lost in the distortions, discontinuities and contradictions inherent in the corporate systems of hierarchy and functionalization.
  • employees are individually rewarded for their contribution to each product. They are not “compensated” for the hours spent at work. If an employee wants to calculate their hourly rate, then they are free to do so however, they are only rewarded for the outcome not the duration of their endeavors.
  • Another simplification is the application of virtual accounts (Profit and Loss (P&L) account and Balance Sheet) on each person within the business.
  • The company systems simply provide a mechanism for cheaply measuring the success of each individual’s choices. For quality the measure is customer returns, for delivery it is an on-time-and-in-full metric and profit is expressed in terms of both pounds sterling and ROI (return on investment).

  • The innumerable direct links back to an external reality -like the fragile ties that bound giant Gulliver, seem much more effective at aligning the presenting culture and the underlying embodied culture, and in doing so work to remove the existing tension.
  • With a culture that responds directly to reality, the rules in the environment can be “bounding” rather than “binding”- limiting rather than instructive; this way individual behavior need not be directed at all. The goal is to free the individual to express himself fully through his work, bounded only by the limits of the law. With clever feedback (self-referencing feedback loops) integrated into the design, the individuals can themselves grow to collectively take charge of the system boundaries, culture and even the environment itself, always minded of the inherent risks they are balancing, leaving the law of the land as the sole artificial boundary.
  • the conventional company, which, instead of rewarding enterprise, trains compliance by suppressing individual initiative under layer upon layer of translation tools.
  • apply accountability to the individual not command-and-control.
  • without the divisive and overbearing management cabal the natural reaction of humans is to combine their efforts
  • a new member of staff at Matt Black Systems
  • recruited by another staff member (sponsor) and they will help you learn the basics of the business management system- they will help you get to know the ropes.
  • jobs are passed to new staff members, a royalty payment can be established on the work passed over.
  • Along with that job you will be given a cash float (risk capital), P&L Account, a Balance Sheet and computer software to help plan and record your activities. Your operation is monitored by your sponsor to see if you increase the margin or volume, and so establish a sustainable operation. Training and mentoring is provided to support the steep learning curve - but without removing the responsibility of producing a return on the sponsor’s risk capital.
  • You will, in the meantime be looking to establish some of your own work for which you will not have to pay a commission or royalty to your sponsor and this will provide you with more profitable operations such that eventually you might pass back to the sponsor the original operation, as it has become your lowest margin activity. It will then find its way to a new employee (along with the associated Balance Sheet risk capital) where the process is repeated by the sponsor.[4]
  • Remuneration for staff is calibrated in a way that reflects the balance of different forces around ‘pay’
  • there is an obligation upon the company to pay a minimum wage even if the profitability of the operation does not support this
  • there are therefore two aspects of the basic pay structure: one is “absolute” and reflects the entrepreneurial skill level of the employee according to a sophisticated grading scale
  • A further 20% of the original profit will be paid into his risk capital account, which will be his responsibility to deploy in any way he sees fit as part of his Balance Sheet. Of the three remaining 20% slices of the original profit, one is paid out as corporation tax, another as a dividend to the shareholders and the last retained as collective risk capital on the company’s balance sheet- a war chest so to speak.
  • Julian Wilson and Andrew Holm sell products / services to their staff (such as office space and software) they have an identical customer/supplier relationship with the other employees.
  • Naturally there are some people that can’t generate a profit. The sponsor’s risk capital will eventually be consumed through pay. After a process of rescue and recovery- where their shortcomings are identified and they are given the opportunity to put them right, they either improve or leave, albeit with a sizeable increase in their skills.
  • there is a gradual process of accustomisation; the void of the new employee is surrounded by others dealing with their particular activities, offering both role models and operations they may wish to relinquish. One step at a time the new employee acquires the skills to become completely self-managing, to increase their margins, to make investments, to find new business, to become a creator of their own success. Ultimately, they learn to be an entrepreneur.
  • responsible autonomy as an alternative vision to traditional hierarchy
  • Matt Black Systems it is not simply commitment that they targeted in their employees, rather they aim for the specific human qualities they sum up as magic- those of curiosity, imagination, creativity, cooperation, self-discipline and realization (bringing ideas to reality).
  • a new form of association of individuals working together under the umbrella of a company structure: a kind of collective autonomy
  • The business is called Matt Black Systems, based in Poole in dorset
  • Turning an organisation on its head- removing all management, establishing a P&L account and Balance Sheet on everyone in the organisation and having customers payment go first into the respective persons P&L account has revolutionised this company. 
  • This innovative company’s approach views business success as wholly reliant upon human agency, and its wellspring at the individual level.
  • problem (of unnecessarily high overheads placed on production) that arguably is behind the decline in western manufacturing
  • over-managed business
  • Autonomy Enables Productivity
  • organizational design brings to light the unconscious socio-philosophical paradigm of the society in which it exists, organizational development points to how change occurs.
  • a mechanistic approach to organization
  • scientific management employs rationalism and determinism in pursuit of efficiency, but leaves no place for self-determination for most people within the system.
  • Command and Control
  • today, a really “modern” view of an organization is more likely to be depicted in terms that are akin to an organism.
  • When it comes to getting work done, the simple question is: are people the problem or the solution?
  • the Taylorist approach may be more real in theory than in practice: its instrumentalist view of the workforce is cursed by unintended consequences. When workers have no space for their own creative expression, when they are treated like automata not unique individuals, when they become demotivated and surly, when they treat their work as a necessary evil; this is no recipe for a functional organization.
  • The natural, human reaction to this is unionization, defiance and even outright rebellion; to counter this, management grows larger and more rigid in pursuit of compliance, organizations become top heavy with staff who do not contribute directly to the process of value creation but wield power over those who do.
  • voluntary slavery of ‘wagery’
  • Even when disgruntled employees strike free and start their own businesses they seem unable to resist the hegemony of the conventional command-and-control approach
  • Making the transition involves adherence to a whole new sociology of work with all the challenging social and psychological implications that brings.
  • first principal that people in the business have the ability to provide the solution
  • In the “theory of constraints” the goal is to align front-line staff into a neat, compact line for maximum efficiency. Surely the most considered approach is to have front-line staff self-align in pursuit of their individual goals?
  • The removal of hierarchy and specialization is key to a massive improvement in both profitability and productivity. In summary: there are no managers in the company, or foremen, or sales staff, or finance departments; the company is not functionally compartmentalized and there is no hierarchy of command. In fact every member of staff operates as a virtual micro-business with their own Profit & Loss account and Balance Sheet, they manage their own work and see processes through from end to end
  • Formal interaction between colleagues takes place via “customer and supplier” relationships.
  • autonomy enables productivity
  • if one creates a space in which staff pursue their own goals and are not paid by the hour, they will focus on their activities not the clock; if they are not told what to do, they will need to develop their own initiative; if they are free to develop their own processes, they will discover through their own creative faculties how to work more productively- in pursuit of their goals
  • The human qualities which are of greatest potential value to the business are: curiosity, imagination, creativity, cooperation, self-discipline and realization (bringing ideas to reality)
  • These qualities are the very ones most likely to be withheld by an individual when the environment is ‘wrong’.
  • Any elements in the business environment that undermine the autonomy and purpose of the individual will see the above qualities withheld
  • High on the list of undermining elements come power-hierarchy and over-specialization
  • the responsibility of the individual is formalized, specified and restricted. An improved system is not one where responsibility is distributed perfectly but rather one where there is simply no opportunity for responsibility to be lost (via the divisions between the chunks). Systems must be reorganized so responsibility -the most essential of qualities -is protected and wholly preserved.
  • Matt Black Systems believe this can only be done by containing the whole responsibility within an individual, holding them both responsible and giving them ‘response-ability’
  • The experience of Matt Black Systems demonstrates that radical change is possible
  • productivity is up 300%, the profit margin is up 10%[3], customer perception has shifted from poor to outstanding, product returns are at less than 1%, “on time and in full” delivery is greater than 96%, pay has increased 100%.
  • staff develop broader and deeper skills and feel greater job security; they get direct feedback from their customers which all go to fuel self-confidence and self-esteem.
  • the staff manage themselves
  • “only variety can absorb variety”.
  • What is particular about their story is that behind it is a very consciously crafted design that surrounds the individualism of each person with hard boundaries of the customer, the law and the business. It is these boundaries rather than the instructive persona of ‘the boss’ that gives rise to the discipline in which individuals can develop. Autonomy is not the same as freedom, at least not in the loose sense of ‘do as you please’. An autonomous person is a person who has become self-governing, who has developed a capacity for self-regulation, quite a different notion from the absence of boundaries. Indeed, it is with establishing the right boundaries that the business philosophy is most concerned. The company provides the crucible in which the individual can develop self-expression but the container itself is bounded. Wilson calls this “designing the void”. This crucible is carefully constructed from an all-encompassing, interconnecting set of boundaries that provide an ultimate limit to behaviours (where they would fall foul of the law or take risks with catastrophic potential). It is an illusion to think, as a director of a company, that you are not engaged in a process of social conditioning; the basis of the culture is both your responsibility and the result of your influence. The trick is to know what needs to be defined and what needs to be left open. The traditional authoritarian, controlling characters that often dominate business are the antithesis of this in their drive to fill this void with process, persona and instruction. Alternatively, creating an environment that fosters enterprise, individuals discover how to be enterprising.

  • This can be done firstly by allowing space for Devil’s advocates, for black sheep, for hearing the voices of those outside of the dominant culture of the organisation and secondly by looking from a holistic perspective of how things interconnect, rather than just relying on experts who are embedded in detail. It emphasises the need to value the generalist, to give value to holistic thinkers.
  • allowing people to imagine different possibilities.
  • scenario planning
  • Permaculture has been described as the science of maximising beneficial relationships.
  • Solutions are to be found in integrated holistic solutions rather than increased specialisation and compartmentalisation
  • The challenge here is to move to seeing business as being part of the geographical community, as being rooted in place, rather than just part of a globalised community. At the moment for many larger businesses, the local is something one pays lip-service to as a source of good PR, something one is passing through, rather than actually being an integral part of the community.
  • This is a profound structural challenge for large organisations. Part of the resilience of the organisation comes from the degree of lateral integration. Resilience is in all solutions, it is the characteristic of ecological systems. If we apply these principles, resilience is one of the emergent properties
  • the notion that big is best needs to be challenged
  • new opportunities are very hard to understand and exploit from a macro level perspective, and are much better done from small scale perspective. It is here that the idea of appropriateness of scale becomes key.
  • more diverse systems have much more inbuilt resilience
  • have a diversity of small businesses, local currencies, food sources, energy sources and so on than if they are just dependent on centralised systems, globalisation’s version of monoculture.
  • not having all your eggs in one basket.
  • In the short term this kind of diversification could reduce profits, but in the longer term it will be more secure
  • this is about the reverse of specialisation, about having a mixed portfolio, and presents a big culture change for businesses.
  • it is a good strategy for business to keep a diverse portfolio of what sustains the business, keep some things that appear to be peripheral. They may not at this stage appear to be a serious part of how the business is run, but in this new world they will increasingly become so
  • ‘edge’
  • the point where two ecosystems meet is often more productive than either of those systems on their own.
  • overlap systems where possible so as to maximise their potential.
  • recognising that innovation doesn’t come from the centre but from fringe thinkers.
  • giving status to the marginal
  • It is important that the business has as many fingers in as many pies as possible, as many interfaces, and recognises that every person working for the business represents it in the community.
  • Natural systems are constantly in flux, evolving and growing.
  • Remaining observant of the changes around you, and not fixing onto the idea that anything around you is fixed or permanent will help too.
  • be flexible, lean and adaptable
  • A healthy approach is to start with no complete plan, to allow the process to be emergent. This is not a time when we can work to a rigid plan as conditions will change so fast. Organisations will need to stay on their toes, without rigid management.

Smart Contracts - 0 views

  • Whether enforced by a government, or otherwise, the contract is the basic building block of a free market economy.
  • A smart contract is a set of promises, specified in digital form, including protocols within which the parties perform on the other promises.
  • The basic idea of smart contracts is that many kinds of contractual clauses (such as liens, bonding, delineation of property rights, etc.) can be embedded in the hardware and software we deal with, in such a way as to make breach of contract expensive (if desired, sometimes prohibitively so) for the breacher.
  • ...77 more annotations...
  • A broad statement of the key idea of smart contracts, then, is to say that contracts should be embedded in the world.
  • And where the vending machine, like electronic mail, implements an asynchronous protocol between the vending company and the customer, some smart contracts entail multiple synchronous steps between two or more parties
  • POS (Point of Sale)
  • EDI (Electronic Data Interchange
  • SWIFT
  • allocation of public network bandwidth via automated auctions
  • Smart contracts reference that property in a dynamic, proactively enforced form, and provide much better observation and verification where proactive measures must fall short.
  • The mechanisms of the world should be structured in such a way as to make the contracts (a) robust against naive vandalism, and (b) robust against sophisticated, incentive compatible (rational) breach.
  • A third category, (c) sophisticated vandalism (where the vandals can and are willing to sacrifice substantial resources), for example a military attack by third parties, is of a special and difficult kind that doesn't often arise in typical contracting, so that we can place it in a separate category and ignore it here.
  • The threat of physical force is an obvious way to embed a contract in the world -- have a judicial system decide what physical steps are to be taken out by an enforcement agency (including arrest, confiscation of property, etc.) in response to a breach of contract
  • It is what I call a reactive form of security.
  • The need to invoke reactive security can be minimized, but not eliminated, by making contractual arrangements verifiable
  • Observation of a contract in progress, in order to detect the first sign of breach and minimize losses, also is a reactive form of security
  • A proactive form of security is a physical mechanism that makes breach expensive
  • From common law, economic theory, and contractual conditions often found in practice, we can distill four basic objectives of contract design
  • observability
  • The disciplines of auditing and investigation roughly correspond with verification of contract performance
  • verifiability
  • The field of accounting is, roughly speaking, primarily concerned with making contracts an organization is involved in more observable
  • privity
  • This is a generalization of the common law principle of contract privity, which states that third parties, other than the designated arbitrators and intermediaries, should have no say in the enforcement of a contract
  • The field of security (especially, for smart contracts, computer and network security), roughly corresponds to the goal of privity.
  • enforceability
  • Reputation, built-in incentives, "self-enforcing" protocols, and verifiability can all play a strong part in meeting the fourth objective
  • Smart contracts often involve trusted third parties, exemplified by an intermediary, who is involved in the performance, and an arbitrator, who is invoked to resolve disputes arising out of performance (or lack thereof)
  • In smart contract design we want to get the most out of intermediaries and arbitrators, while minimizing exposure to them
  • Legal barriers are the most severe cost of doing business across many jurisdictions. Smart contracts can cut through this Gordian knot of jurisdictions
  • Where smart contracts can increase privity, they can decrease vulnerability to capricious jurisdictions
  • Secret sharing
  • The field of Electronic Data Interchange (EDI), in which elements of traditional business transactions (invoices, receipts, etc.) are exchanged electronically, sometimes including encryption and digital signature capabilities, can be viewed as a primitive forerunner to smart contracts
  • One important task of smart contracts, that has been largely overlooked by traditional EDI, is critical to "the meeting of the minds" that is at the heart of a contract: communicating the semantics of the protocols to the parties involved
  • There is ample opportunity in smart contracts for "smart fine print": actions taken by the software hidden from a party to the transaction.
  • Thus, via hidden action of the software, the customer is giving away information they might consider valuable or confidential, but the contract has been drafted, and transaction has been designed, in such a way as to hide those important parts of that transaction from the customer.
  • To properly communicate transaction semantics, we need good visual metaphors for the elements of the contract. These would hide the details of the protocol without surrendering control over the knowledge and execution of contract terms
  • Protocols based on mathematics, called cryptographic protocols, tre the basic building blocks that implement the improved tradeoffs between observability, verifiability, privity, and enforceability in smart contracts
  • secret key cryptography,
  • Public key cryptography
  • digital signatures
  • blind signature
  • Where smart contracts can increase observability or verifiability, they can decrease dependence on these obscure local legal codes and enforcement traditions
  • zero-knowledge interactive proof
  • digital mix
  • Keys are not necessarily tied to identities, and the task of doing such binding turns out to be more difficult than at first glance.
  • All public key operation are are done inside an unreadable hardware board on a machine with a very narrow serial-line connection (ie, it carries only a simple single-use protocol with well-verified security) to a dedicated firewall. Such a board is available, for example, from Kryptor, and I believe Viacrypt may also have a PGP-compatable board. This is economical for central sites, but may be less practical for normal users. Besides better security, it has the added advantage that hardware speeds up the public key computations.
  • If Mallet's capability is to physically sieze the machine, a weaker form of key protection will suffice. The trick is to hold the keys in volatile memory.
  • The data is still vulnerable to a "rubber hose attack" where the owner is coerced into revealing the hidden keys. Protection against rubber hose attacks might require some form of Shamir secret sharing which splits the keys between diverse phgsical sites.
  • How does Alice know she has Bob's key? Who, indeed, can be the parties to a smart contract? Can they be defined just by their keys? Do we need biometrics (such as autographs, typed-in passwords, retina scans, etc.)?
  • The public key cryptography software package "Pretty Good Privacy" (PGP) uses a model called "the web of trust". Alice chooses introducers whom she trusts to properly identify the map between other people and their public keys. PGP takes it from there, automatically validating any other keys that have been signed by Alice's designated introducers.
  • 1) Does the key actually belong to whom it appears to belong? In other words, has it been certified with a trusted signature?
  • 2) Does it belong to an introducers, someone you can trust to certify other keys?
  • 3) Does the key belong to someone you can trust to introduce other introducers? PGP confuses this with criterion (2). It is not clear that any single person has enough judgement to properly undertake task (3), nor has a reasonable institution been proposed that will do so. This is one of the unsolved problems in smart contracts.
  • PGP also can be given trust ratings and programmed to compute a weighted score of validity-- for example, two marginally trusted signatures might be considered as credible as one fully trusted signature
  • Notaries Public Two different acts are often called "notarization". The first is simply where one swears to the truth of some affidavit before a notary or some other officer entitled to take oaths. This does not require the notary to know who the affiant is. The second act is when someone "acknowledges" before a notary that he has executed a document as ``his own act and deed.'' This second act requires the notary to know the person making the acknowledgment.
  • "Identity" is hardly the only thing we might want map to a key. After all, physical keys we use for our house, car, etc. are not necessarily tied to our identity -- we can loan them to trusted friends and relatives, make copies of them, etc. Indeed, in cyberspace we might create "virtual personae" to reflect such multi-person relationships, or in contrast to reflect different parts of our personality that we do not want others to link. Here is a possible classification scheme for virtual personae, pedagogically presented:
  • A nym is an identifier that links only a small amount of related information about a person, usually that information deemed by the nym holder to be relevant to a particular organization or community
  • A nym may gain reputation within its community.
  • With Chaumian credentials, a nym can take advantage of the positive credentials of the holder's other nyms, as provably linked by the is-a-person credential
  • A true name is an identifier that links many different kinds of information about an person, such as a full birth name or social security number
  • As in magick, knowing a true name can confer tremendous power to one's enemies
  • A persona is any perstient pattern of behavior, along with consistently grouped information such as key(s), name(s), network address(es), writing style, and services provided
  • A reputable name is a nym or true name that has a good reputation, usually because it carries many positive credentials, has a good credit rating, or is otherwise highly regarded
  • Reputable names can be difficult to transfer between parties, because reputation assumes persistence of behavior, but such transfer can sometimes occur (for example, the sale of brand names between companies).
  • Blind signatures can be used to construct digital bearer instruments, objects identified by a unique key, and issued, cleared, and redeemed by a clearing agent.
  • The clearing agent prevents multiple clearing of particular objects, but can be prevented from linking particular objects one or both of the clearing nyms who transferred that object
  • These instruments come in an "online" variety, cleared during every transfer, and thus both verifiable and observable, and an "offline" variety, which can be transfered without being cleared, but is only verifiable when finally cleared, by revealing any the clearing nym of any intermediate holder who transfered the object multiple times (a breach of contract).
  • To implement a full transaction of payment for services, we need more than just the digital cash protocol; we need a protocol that guarantees that service will be rendered if payment is made, and vice versa
  • A credential is a claim made by one party about another. A positive credential is one the second party would prefer to reveal, such as a degree from a prestigious school, while that party would prefer not to reveal a negative credential such as a bad credit rating.
  • A Chaumian credential is a cryptographic protocol for proving one possesses claims made about onself by other nyms, without revealing linkages between those nyms. It's based around the is-a-person credential the true name credential, used to prove the linkage of otherwise unlinkable nyms, and to prevent the transfer of nyms between parties.
  • Another form of credential is bearer credential, a digital bearer instrument where the object is a credential. Here the second party in the claim refers to any bearer -- the claim is tied only to the reputable name of issuing organization, not to the nym or true name of the party holding the credential.
  • Smart Property We can extend the concept of smart contracts to property. Smart property might be created by embedding smart contracts in physical objects. These embedded protocols would automatically give control of the keys for operating the property to the party who rightfully owns that property, based on the terms of the contract. For example, a car might be rendered inoperable unless the proper challenge-response protocol is completed with its rightful owner, preventing theft. If a loan was taken out to buy that car, and the owner failed to make payments, the smart contract could automatically invoke a lien, which returns control of the car keys to the bank. This "smart lien" might be much cheaper and more effective than a repo man. Also needed is a protocol to provably remove the lien when the loan has been paid off, as well as hardship and operational exceptions. For example, it would be rude to revoke operation of the car while it's doing 75 down the freeway.
  • Smart property is software or physical devices with the desired characteristics of ownership embedded into them; for example devices that can be rendered of far less value to parties who lack possesion of a key, as demonstrated via a zero knowledge interactive proof
  • One method of implementing smart property is thru operation necessary data (OND): data necessary to the operation of smart property.
  • A smart lien is the sharing of a smart property between parties, usually two parties called the owner and the lienholder.
  • Many parties, especially new entrants, may lack this reputation capital, and will thus need to be able to share their property with the bank via secure liens
  • What about extending the concept of contract to cover agreement to a prearranged set of tort laws? These tort laws would be defined by contracts between private arbitration and enforcement agencies, while customers would have a choice of jurisdictions in this system of free-market "governments".
  • If these privately practiced law organizations (PPLs for short) bear ultimate responsibility for the criminal activities of their customers, or need to insure lack of defection or future payments on the part of customers, they may in turn ask for liens against their customers, either in with contractual terms allowing arrest of customers under certain conditions
  • Other important areas of liability include consumer liability and property damage (including pollution). There need to mechanisms so that, for example, pollution damage to others' persons or property can be assessed, and liens should exist so that the polluter can be properly charged and the victims paid. Where pollution is quantifiable, as with SO2 emissions, markets can be set up to trade emission rights. The PPLs would have liens in place to monitor their customer's emissions and assess fees where emission rights have been exceeded.

    "Three-axis distributed fiber optic strain measurement in 3D woven composite structures   Paper 8690-6 Time: 1:50 PM - 2:10 PM Author(s): Matt Castellucci, Evan M. Lally, Sandra Klute, Luna Innovations Inc. (United States); David Lowry, NASA Johnson Space Ctr. (United States) Hide Abstract Add to My Schedule  Recent advancements in composite materials technologies have broken further from traditional designs and require advanced instrumentation and analysis capabilities. Success or failure is highly dependent on design analysis and manufacturing processes. By monitoring smart structures throughout manufacturing and service life, residual and operational stresses can be assessed and structural damage identified. Composite smart structures can be manufactured by integrating fiber optic sensors into existing composite materials processes such as layup, filament winding and three-dimensional weaving. In this work optical fiber was integrated into 3D woven composite parts at a commercial woven products manufacturing facility. The fiber was then used to monitor the structures during a VARTM manufacturing process, and subsequent static and dynamic testing. Low cost telecommunications-grade optical fiber acts as the sensor using a high resolution commercial Optical Frequency Domain Reflectometer (OFDR) system providing distributed strain measurement at spatial resolutions as low as 2mm. Strain measurements using the optical fiber sensors are correlated to resistive strain gauge measurements during static structural loading."

Density Design | Fineo - 1 views

    DensityDesign develops research projects in the domain of visual representation, stemming from a design perspective. Our research interests include theoretical and epistemological reflections on visualizations and analyses of their cognitive underpinnings, in addition to the development of large frameworks for data visualization and ad-hoc solutions for speculative narration. We adopt an open approach to visualization, working from visual storytelling to visual analytics. Design is, thus, treated more like a proper language than a tool. We use this language in practice to define a new-visual-epistemology.

  • ...75 more annotations...
  • In a 3D printer today, what you can make is limited by the size of the machine. The geometry is external
  • is the Lego tower is more accurate than the child because the constraint of assembling the bricks lets you detect and correct errors
  • That's the exponential scaling for working reliably with unreliable parts
  • Because the parts have a discrete state, it means in joining them you can detect and correct errors
  • detect and correct state to correct errors to get an exponential reduction in error, which gives you an exponential increase in complexity
  • The next one is you can join Lego bricks made out of dissimilar materials.
  • The last one is when you're done with Lego you don't put it in the trash; you take it apart and reuse it because there's state in the materials. In a forest there's no trash; you die and your parts get disassembled and you're made into new stuff. When you make a 3D print or laser cut, when you're done there's recycling attempts but there's no real notion of reusing the parts
  • The metrology coming from the parts, detecting and correcting errors, joining dissimilar materials, disconnecting, reusing the components
  • On the very smallest scale, the most exciting work on digital fabrication is the creation of life from scratch. The cell does everything we're talking about. We've had a great collaboration with the Venter Institute on microfluidic machinery to load designer genomes into cells. One step up from that we're developing tabletop chip fab instead of a billion dollar fab, using discrete assembly of blocks of electronic materials to build things like integrated circuits in a tabletop process
  • a child can make a Lego structure bigger than themself
  • There's a series of books by David Gingery on how to make a machine shop starting with charcoal and iron ore.
  • There are twenty amino acids. With those twenty amino acids you make the motors in the molecular muscles in my arm, you make the light sensors in my eye, you make my neural synapses. The way that works is the twenty amino acids don't encode light sensors, or motors. They’re very basic properties like hydrophobic or hydrophilic. With those twenty properties you can make you. In the same sense, digitizing fabrication in the deep sense means that with about twenty building blocks—conducting, insulating, semiconducting, magnetic, dielectric—you can assemble them to create modern technology
  • By discretizing those three parts we can make all those 500,000 resistors, and with a few more parts everything else.
  • Now, there's a casual sense, which means a computer controls something to make something, and then there's the deep sense, which is coding the materials. Intellectually, that difference is everything but now I'm going to explain why it doesn't matter.
  • Then in turn, the next surprise was they weren't there for research, they weren't there for theses, they wanted to make stuff. I taught additive, subtractive, 2D, 3D, form, function, circuits, programming, all of these skills, not to do the research but just using the existing machines today
  • What they were answering was the killer app for digital fabrication is personal fabrication, meaning, not making what you can buy at Walmart, it’s making what you can't buy in Walmart, making things for a market of one person
  • The minicomputer industry completely misread PCs
  • the Altair was life changing for people like me. It was the first computer you could own as an individual. But it was almost useless
  • It was hard to use but it brought the cost from a million dollars to 100,000 and the size from a warehouse down to a room. What that meant is a workgroup could have one. When a workgroup can have one it meant Ken Thompson and Dennis Ritchie at Bell Labs could invent UNIX—which all modern operating systems descend from—because they didn't have to get permission from a whole corporation to do it
  • At the PC stage what happened is graphics, storage, processing, IO, all of the subsystems got put in a box
  • To line that up with fabrication, MIT's 1952 NC Mill is similar to the million-dollar machines in my lab today. These are the mainframes of fab. You need a big organization to have them. The fab labs I'll tell you about are exactly analogous to the cost and complexity of minicomputers. The machines that make machines I'll tell you about are exactly analogous to the cost and complexity of the hobbyist computers. The research we're doing, which is leading up to the Star Trek Replicator, is what leads to the personal fabricator, which is the integrated unit that makes everything
  • conducting, resistive, insulating.
  • The fab lab is 2 tons, a $100,000 investment. It fills a few thousand square feet, 3D scanning and printing, precision machining, you can make circuit boards, molding and casting tooling, computer controlled cutting with a knife, with a laser, large format machining, composite layup, surface mount rework, sensors, actuators, embedded programming— technology to make technology.
  • Ten years you can just plot this doubling. Today, you can send a design to a fab lab and you need ten different machines to turn the data into something. Twenty years from now, all of that will be in one machine that fits in your pocket.
  • We've been living with this notion that making stuff is an illiberal art for commercial gain and it's not part of the means of expression. But, in fact, today, 3D printing, micromachining, and microcontroller programming are as expressive as painting paintings or writing sonnets but they're not means of expression from the Renaissance. We can finally fix that boundary between art and artisans
  • You don't go to a fab lab to get access to the machine; you go to the fab lab to make the machine.
  • Over the next maybe five years we'll be transitioning from buying machines to using machines to make machines. Self-reproducing machines
  • But they still have consumables like the motors, and they still cut or squirt. Then the interesting transition comes when we go from cutting or printing to assembling and disassembling, to moving to discretely assembled materials
  • because if anybody can make anything anywhere, it challenges everything
    • Kurt Laitner
       
      great quote (replace challenges with changes for effect)
  • Now, the biggest surprise for me in this is I thought the research was hard. It's leading to how to make the Star Trek Replicator. The insight now is that's an exercise in embodied computation—computation in materials, programming their construction. Lots of work to come, but we know what to do
  • And that's when you do tabletop chip fab or make airplanes. That's when technical trash goes away because you can disassemble. 
  • irritated by the maker movement for the failure in mentoring
  • At something like a Maker Faire, there's hall after hall of repeated reinventions of bad 3D printers and there isn't an easy process to take people from easy to hard
  • We started a project out of desperation because we kept failing to succeed in working with existing schools, called the Fab Academy. Now, to understand how that works, MIT is based on scarcity. You assume books are scarce, so you have to go there for the library; you assume tools are scarce, so you have to go there for the machines; you assume people are scarce, so you have to go there to see them; and geography is scarce. It adds up to we can fit a few thousand people at a time. For those few thousand people it works really well. But the planet is a few billion people. We're off by six orders of magnitude. 
  • Next year we're starting a new class with George Church that we've called "How to Grow Almost Anything", which is using fab labs to make bio labs and then teach biotech in it. What we're doing is we're making a new global kind of university
  • Amusingly, I went to my friends at Educause about accrediting the Fab Academy and they said, "We love it. Where are you located?" And I said, "Yes" and they said, "No." Meaning, "We're all over the earth." And they said, "We have no mechanism. We're not allowed to do that. There's no notion of global accreditation."
  • Then they said something really helpful: "Pretend."
  • Once you have a basic set of tools, you can make all the rest of the tools
  • The way the Fab Academy works, in computing terms, it's like the Internet. Students have peers in workgroups, with mentors, surrounded by machines in labs locally. Then we connect them globally by video and content sharing and all of that. It's an educational network. There are these critical masses of groups locally and then we connect them globally
  • You still have Microsoft or IBM now but, with all respect to colleagues there, arguably that's the least interesting part of software
  • To understand the economic and social implications, look at software and look at music to understand what's happening now for fabrication
  • There's a core set of skills a place like MIT can do but it alone doesn't scale to a billion people. This is taking the social engineering—the character of MIT—but now doing it on this global scale.
  • Mainframes didn't go away but what opened up is all these tiers of software development that weren't economically viable
  • If you look at music development, the most interesting stuff in music isn't the big labels, it's all the tiers of music that weren't viable before
  • You can make music for yourself, for one, ten, 100, 1,000, a million. If you look at the tracks on your device, music is now in tiers that weren't economically viable before. In that example it's a string of data and it becomes a sound. Now in digital fab, it's a string of data and it becomes a thing.
  • What is work? For the average person—not the people who write for Edge, but just an average person working—you leave home to go to a place you'd rather not be, doing a repetitive operation you'd rather not do, making something designed by somebody you don't know for somebody you'll never see, to get money to then go home and buy something. But what if you could skip that and just make the thing?
    • Kurt Laitner
       
      !!!
  • It took about ten years for the dot com industry to realize pretty much across the board you don't directly sell the thing. You sell the benefits of the thing
  • 2016 it's in Shenzhen because they're pivoting from mass manufacturing to enabling personal fabrication. We've set Shenzhen as the goal in 2016 for Fab Lab 2.0, which is fab labs making fab labs
  • To rewind now, you can send something to Shenzhen and mass manufacture it. There's a more interesting thing you can do, which is you go to market by shipping data and you produce it on demand locally, and so you produce it all around the world.
  • But their point was a lot of printers producing beautiful pages slowly scales if all the pages are different
  • In the same sense it scales to fabricate globally by doing it locally, not by shipping the products but shipping the data.
  • It doesn't replace mass manufacturing but mass manufacturing becomes the least interesting stuff where everybody needs the same thing. Instead, what you open up is all these tiers that weren't viable before
  • There, they consider IKEA the enemy because IKEA defines your taste. Far away they make furniture and flat pack it and send it to a big box store. Great design sense in Barcelona, but 50 percent youth unemployment. A whole generation can't work. Limited jobs. But ships come in from the harbor, you buy stuff in a big box store. And then after a while, trucks go off to a trash dump. They describe it as products in, trash out. Ships come in with products, trash goes out
    • Kurt Laitner
       
      worse actually.. the trash stays
  • The bits come and go, globally connected for knowledge, but the atoms stay in the city.
  • instead of working to get money to buy products made somewhere else, you can make them locally
    • Kurt Laitner
       
      this may solve greece's problem, walk away from debt, you can't buy other people's (country's) stuff anymore, so make it all yourself
  • The biggest tool is a ShotBot 4'x8'x1' NC mill, and you can make beautiful furniture with it. That's what furniture shops use
  • Anything IKEA makes you can make in a fab lab
  • it means you can make many of the things you consume directly rather than this very odd remote economic loop
  • the most interesting part of the DIY phone projects is if you're making a do-it-yourself phone, you can also start to make the things that the phones talk to. You can start to build your own telco providers where the users provide the network rather than spending lots of money on AT&T or whoever
  • Traditional manufacturing is exactly replaying the script of the computer companies saying, "That's a toy," and it's shining a light to say this creates entirely new economic activity. The new jobs don't come back to the old factories. The ability to make stuff on demand is creating entirely new jobs
  • To keep playing that forward, when I was in Barcelona for the meeting of all these labs hosted by the city architect and the city, the mayor, Xavier Trias, pushed a button that started a forty-year countdown to self-sufficiency. Not protectionism
  • I need high-torque efficient motors with integrated lead screws at low cost, custom-produced on demand. All sorts of the building blocks that let us do what I'm doing currently rest on a global supply chain including China's manufacturing agility
  • The short-term answer is you can't get rid of them because we need them in the supply chain. But the long-term answer is Shenzhen sees the future isn't mass producing for everybody. That's a transitional stage to producing locally
  • My description of MIT's core competence is it's a safe place for strange people
  • The real thing ultimately that's driving the fab labs ... the vacuum we filled is a technical one. The means to make stuff. Nobody was providing that. But in turn, the spaces become magnets. Everybody talks about innovation or knowledge economy, but then most things that label that strangle it. The labs become vehicles for bright inventive people who don't fit locally. You can think about the culture of MIT but on this global scale
  • My allegiance isn't to any one border, it's to the brainpower of the planet and this is building the infrastructure to scale to that brainpower
  • If you zoom from transistors to microcode to object code to a program, they don't look like each other. But if we take this room and go from city, state, country, it's hierarchical but you preserve geometry
  • Computation violates geometry unlike most anything else we do
  • The reason that's so important for the digital fabrication piece is once we build molecular assemblers to build arbitrary systems, you don't want to then paste a few lines of code in it. You need to overlay computation with geometry. It's leading to this complete do-over of computer science
  • If you take digital fab, plus the real sense of Internet of Things—not the garbled sense—plus the real future of computing aligning hardware and software, it all adds up to this ability to program reality
  • I run a giant video infrastructure and I have collaborators all over the world that I see more than many of my colleagues at MIT because we're all too busy on campus. The next Silicon Valley is a network, it's not a place. Invention happens in these networks.
  • When Edwin Land was kicked out of Polaroid, he made the Rowland Institute, which was making an ideal research institute with the best facilities and the best people and they could do whatever they want. But almost nothing came from it because there was no turnover of the gene pool, there was no evolutionary pressure.  
  • the wrong way to do research, which is to believe there's a privileged set of people that know more than anybody else and to create a barrier that inhibits communication from the inside to the outside
  • you need evolutionary pressure, you need traffic, you need to be forced to deal with people you don't think you need to encounter, and you need to recognize that to be disruptive it helps to know what people know
  • For me the hardest thing isn't the research. That's humming along nicely. It's that we're finding we have to build a completely new kind of social order and that social entrepreneurship—figuring out how you live, learn, work, play—is hard and there's a very small set of people who can do that kind of organizational creation.

  • resistance to neoliberalism
  • we are at a stage of emergence
  • difficulty of implementing full p2p solutions in the current dominant system
  • At this stage, there is a co-dependency between peer producers creating value, and for-profit firms ‘capturing that value’, but they both need each other.
  • Peer producers need a business ecology to insure the social reproduction of their system and financial sustainability of its participants, and capital needs the positive externalities of social cooperation which flow from p2p collaboration.
  • peer producing communities should create their own ‘mission-oriented’ social businesses, so that the surplus value remains with the value creators, i.e. the commoners themselves, but this is hardly happening now.
  • Instead what we see is a mutual accomodation between netarchical capital on one side, and peer production communities on the other.
  • the horizontal meets the vertical
  • mostly hybrid ‘diagonal’ adaptations
  • For peer producers the question becomes, if we cannot create our own fully autonomous institutions, how can we adapt while maintaining maximum autonomy and sustainability as a commons and as a community.
  • Why p2p have failed to create successful alternatives in some areas?
  • In commons-oriented peer production, where people aggegrate around a common object which requires deep cooperation, they usually have their own infrastructures of cooperation and a ecology combining community, a for-benefit association managing the infrastructure, and for-profit companies operating on the market place; in the sharing economy, where individuals merely share their own expressions, third party platforms are the norm. It is clear that for-profit companies have different priorities, and want to enclose value so that it can be sold on the marketplace. This in fact the class struggle of the p2p era, the struggle between communities and corporations around various issues because of partly differential interests.
  • Even commercially controlled platforms are being used for a massive horizontalisation and self-aggregation of human relationships, and communities, including political and radical groups are effectively using them to mobilize. What’s important is not just to focus on the limitations and intentions of the platform owners, but to use whatever we can to strengthen the autonomy of peer communities.
  • requires a clever adaptation
  • use for our own benefit
  • The fact today is that capital is still capable of marshaling vast financial and material resources, so that it can create,
  • platforms that can easily and quickly offer services, creating network effects
  • without network effects, there is no ‘there’ there, just an empty potential platform.
  • p2p activists should work on both fronts
  • using mainstream platforms for spreading their ideas and culture and reach greater numbers of people, while also developing their own autonomous media ecologies, that can operate independently, and the latter is an engagement for the ‘long haul’, i.e. the slow construction of an alternative lifeworld.
  • The commons and p2p are really just different aspects of the same phenomena; the commons is the object that p2p dynamics are building; and p2p takes place wherever there are commons.
  • So both p2p and the commons, as they create abundant (digital) or sufficient (material) value for the commoners, at the same time create opportunities to create added value for the marketplace. There is no domain that is excluded from p2p, no field that can say, “we wouldn’t be stronger by opening up to participation and community dynamics”. And there is no p2p community that can say, we are in the long term fully sustainable within the present system, without extra resources coming from the market sector.
  • One trend is the distribution of current infrastructures and practices, i.e. introducing crowdsourcing, crowdfunding, social lending, digital currencies, in order to achieve wider participation in current practices. That is a good thing, but not sufficient. All the things that I mention above, move to a distributed infrastructure, but do not change the fundamental logic of what they are doing.
  • we are talking about the distribution of capitalism, not about a deeper change in the logic of our economy.
  • No matter how good you are, no matter how much capital you have to hire the best people, you cannot compete with the innovative potential of open global communities.
  • the p2p dynamics
  • the new networked culture
  • the opposite is also happening, as we outlined above, more and more commons-oriented value communities are creating their own entrepreneurial coalitions. Of course, some type of companies, because of their monopoly positions and legacy systems, may have a very difficult time undergoing that adaptation, in which case new players will appear that can do it more effectively.
  • the corporate form is unable to deal with ecological and sustainability issues, because its very DNA, the legal obligation to enrich the shareholders, makes its strive to lower input costs,  and ignore externalities.
  • we need new corporate structures, a new type of market entity, for which profit is a means, but not an end, dedicated to a ‘benefit‘, a ‘mission’, or the sustenance of a particular community and/or commons.
  • abundance destroys scarcity and therefore markets
  • open design community
  • will inherently design for sustainability
  • for inclusion
  • conceive more distributed forms of manufacturing
  • entrepreneurs attaching themselves to open design projects start working from an entirely different space, even if they still use the classic corporate form. Prevent the sharing of sustainability designs through IP monopolies is also in my view unethical and allowing such patents should be a minimalist option, not a maximalist one.
  • The high road scenario proposes an enlightened government that ‘enables and empowers’ social production and value creation and allows a much smoother transition to p2p models; the low road scenario is one in which no structural reforms take place, the global situation descends into various forms of chaos, and p2p becomes a survival and resilience tactic in extremely difficult social, political and economic circumstances.
  • accelerated end of capitalism
  • Making sure that we get a better alternative is actually the historical task of the p2p movement. In other words, it depends on us!
  • I don’t really think in terms of technological breakthroughs, because the essential one, globally networked collective intelligence enabled by the internetworks, is already behind us; that is the major change, all other technological breakthroughs will be informed by this new social reality of the horizontalisation of our civilisation. The important thing now is to defend and extend our communication and organisation rights, against a concerted attempt to turn back the clock. While the latter is really an impossibility, this does not mean that the attempts by governments and large corporations cannot create great harm and difficulties. We need p2p technology to enable the global solution finding and implementation of the systemic crises we are facing.

Towards a Material Commons | Guerrilla Translation! - 0 views

  • the modes of communication we use are very tightly coupled with the modes of production that finance them
  • I’m focused on the policy formation around this transition to a new, open knowledge and commons-based economy, and that’s the research work I’m doing here
  • The problem is I can only make a living by still working for capital.
  • ...88 more annotations...
  • We now have a technology which allows us to globally scale small group dynamics, and to create huge productive communities, self-organized around the collaborative production of knowledge, code, and design. But the key issue is that we are not able to live from that, right
  • A lot of co-ops have been neo-liberalizing, as it were, have become competitive enterprises competing against other companies but also against other co-ops, and they don’t share their knowledge
  • We cannot create our own livelihood within that sphere
  • instead of having a totally open commons, which allows multinationals to use our commons and reinforce the system of capital, the idea is to keep the accumulation within the sphere of the commons.
  • The result would be a type of open cooperative-ism, a kind of synthesis or convergence between peer production and cooperative modes of production
  • then the material work, the work of working for clients and making a livelihood, would be done through co-ops
  • But it hasn’t had much of a direct connection to this emerging commons movement, which shares so many of the values and  principles of the traditional cooperative movement.
  • There’s also a lot of peer-to-peer work going on, but it’s not very well versed around issues like cooperative organization, formal or legal forms of ownership, which are based on reciprocity and cooperation, and how to interpret the commons vision with a structure, an organizational structure and a legal structure that actually gives it economic power, market influence, and a means of connecting it to organizational forms that have durability over the long-term.
  • The young people, the developers in open source or free software, the people who are in co-working centers, hacker spaces, maker spaces. When they are thinking of making a living, they think startups
  • They have a kind of generic reaction, “oh, let’s do a startup”, and then they look for venture funds. But this is a very dangerous path to take
  • Typically, the venture capital will ask for a controlling stake, they have the right to close down your start up whenever they feel like it, when they feel that they’re not going to make enough money
  • Don’t forget that with venture capital, only 1 out of 10 companies will actually make it, and they may be very rich, but it’s a winner-take-all system
  • we don’t have what Marx used to call social reproduction
  • I would like John to talk about the solidarity co-ops, and how that integrates the notion of the commons or the common good in the very structure of the co-op
  • They don’t have a commons of design or code, they privatize and patent, just like private competitive enterprise, their knowledge
  • Cooperatives, which are basically a democratic and collective form of enterprise where members have control rights and democratically direct the operations of the co-op, have been the primary stakeholders in any given co-op – whether it’s a consumer co-op, or a credit union, or a worker co-op.
  • Primarily, the co-op is in the service of its immediate members
  • What was really fascinating about the social co-ops was that, although they had members, their mission was not only to serve the members but also to provide service to the broader community
  • In the city of Bologna, for example, over 87% of the social services provided in that city are provided through contract with social co-ops
  • democratically run
  • much more participatory, and a much more engaged model
  • The difference, however, is that the structure of social co-ops is still very much around control rights, in other words, members have rights of control and decision-making within how that organization operates
  • And it is an incorporated legal structure that has formal recognition by the legislation of government of the state, and it has the power, through this incorporated power, to negotiate with and contract with government for the provision of these public services
  • In Québec they’re called Solidarity co-ops
  • So, the social economy, meaning organizations that have a mutual aim in their purpose, based on the principles of reciprocity, collective benefit, social benefit, is emerging as an important player for the design and delivery of public services
  • This, too, is in reaction to the failure of the public market for provision of services like affordable housing or health care or education services
  • This is a crisis in the role of the state as a provider of public services. So the question has emerged: what happens when the state fails to provide or fulfill its mandate as a provider or steward of public goods and services, and what’s the role of civil society and the social economy in response?
  • we have commonses of knowledge, code and design. They’re more easily created, because as a knowledge worker, if you have access to the network and some means, however meager, of subsistence, through effort and connection you can actually create knowledge. However, this is not the case if you move to direct physical production, like the open hardware movement
  • I originally encountered Michel after seeing some talks by Benkler and Lessig at the Wizard of OS 4, in 2006, and I wrote an essay criticizing that from a materialist perspective, it was called “The creative anti-commons and the poverty of networks”, playing on the terms that both those people used.
  • In hardware, we don’t see that, because you need to buy material, machines, plastic, metal.
  • Some people have called the open hardware community a “candy” economy, because if you’re not part of these open hardware startups, you’re basically not getting anything for your efforts
  • democratic foundations like the Apache foundation
  • They conceive of peer production, especially Benkler, as being something inherently immaterial, a form of production that can only exist in the production of immaterial wealth
  • From my materialist point of view, that’s not a mode of production, because a mode of production must, in the first place, reproduce its productive inputs, its capital, its labor, and whatever natural wealth it consumes
  • From a materialist point of view, it becomes  obvious that the entire exchange value produced in these immaterial forms would be captured by the same old owners of materialist wealth
  • different definition of peer production
  • independent producers collectively sharing a commons of productive assets
  • I wanted to create something like a protocol for the formation and allocation of physical goods, the same way we have TCP/IP and so forth, as a way to allocate immaterial goods
  • share and distribute and collectively create immaterial wealth, and become independent producers based on this collective commons.
  • One was the Georgist idea of using rent, economic rent, as a fundamental mutualizing source of wealth
  • Mutualizing unearned income
  • So, the unearned income, the portion of income derived from ownership of productive assets is evenly distributed
  • This protocol would seek to normalize that, but in a way that doesn’t require administration
  • typical statist communist reaction to the cooperative movement is saying that cooperatives can exclude and exploit one another
  • But then, as we’ve seen in history, there’s something that develops called an administrative class,  which governs over the collective of cooperatives or the socialist state, and can become just as counterproductive and often exploitive as capitalist class
  • So, how do we create cooperation among cooperatives, and distribution of wealth among cooperatives, without creating this administrative class?
  • This is why I borrowed from the work of Henry George and Silvio Gesell in created this idea of rent sharing.
  • This is not done administratively, this is simply done as a protocol
  • The idea is that if a cooperative wants an asset, like, an example is if one of the communes would like to have a tractor, then essentially the central commune is like a bond market. They float a bond, they say I want a tractor, I am willing to pay $200 a month for this tractor in rent, and other members of the cooperative can say, hey, yeah, that’s a good idea,we think that’s a really good allocation of these productive assets, so we are going to buy these bonds. The bond sale clears, the person gets the tractor, the money from the rent of the tractor goes back to clear the bonds, and  after that, whatever further money is collected through the rent on this tractor – and I don’t only mean tractors, same would be applied to buildings, to land, to any other productive assets – all this rent that’s collected is then distributed equally among all of the workers.
  • The idea is that people earn income not only by producing things, but by owning the means of production, owning productive assets, and our society is unequal because the distribution of productive assets is unequal
  • This means that if you use your exact per capita share of property, no more no less than what you pay in rent and what you received in social dividend, will be equal
  • But if you’re not working at that time, because you’re old, or otherwise unemployed, then obviously the the productive assets that you will be using will be much less than the mean and the median, so what you’ll receive as dividend will be much more than what you pay in rent, essentially providing a basic income
  • venture communism doesn’t seek to control the product of the cooperatives
  • It doesn’t seek to limit, control, or even tell them how they should distribute it, or under what means; what they produce is entirely theirs, it’s only the collective management of the commons of productive assets
  • On paper this would seem to work, but the problem is that this assumes that we have capital to allocate in this way, and that is not the case for most of the world workers
  • how do we get to that stage?
  • other two being counter politics and insurrectionary finance
  • do we express our activism through the state, or do we try to achieve our goals by creating the alternative society outside
  • pre-figurative politics, versus statist politics
  • My materialist background tells me that when you sell your labor on the market, you have nothing more than your subsistence costs at the end of it, so where is this wealth meant to come from
  • I believe that the only reason that we have any extra wealth beyond subsistence is because of organized social political struggle; because we have organized in labor movements, in the co-op movement, and in other social forms
  • To create the space for prefiguring presupposes engagement with the state, and struggle within parliaments, and struggle within the public social forum
  • Instead, we should think that no, we must engage in the state in order to protect our ability to have alternative societies
  • We can only get rid of the state in these areas once we have alternative, distributed, cooperative means to provide those same functions
  • We can only eliminate the state from these areas once they actually exist, which means we actually have to build them
  • What I mean by insurrectionary finance is that we have to acknowledge that it’s not only forming capital and distributing capital, it’s also important how intensively we use capital
  • I’m not proposing that the cooperative movement needs to engage in the kind of derivative speculative madness that led to the financial crisis, but at the same time we can’t… it can’t be earn a dollar, spend a dollar
  • We have to find ways to create liquidity
  • to deal with economic cycles
  • they did things the organized left hasn’t been able to do, which is takeover industrial means of production
  • if they can take over these industrial facilities, just in order to shut them down and asset strip them, why can’t we take them over and mutualize them?
  • more ironic once you understand that the source of investment that Milken and his colleagues were working with were largely workers pension funds
  • idea of venture communism
  • pooling, based on the capture of unearned income
  • in Québec, there is a particular form of co-op that’s been developed that allows small or medium producers to pool their capital to purchase machinery and to use it jointly
  • The other idea I liked was trying to minimize a management class
  • much more lean and accountable because they are accountable to boards of directors that represent the interests of the members
  • I’ve run into this repeatedly among social change activists who immediately recoil at the notion of thinking about markets and capital, as part of their change agenda
  • I had thought previously, like so many, that economics is basically a bought discipline, and that it serves the interests of existing elites. I really had a kind of reaction against that
  • complete rethinking of economics
  • recapture the initiative around vocabulary, and vision, with respect to economics
  • reimagining and reinterpreting, for a popular and common good, the notion of market and capital
  • advocating for a vision of social change that isn’t just about politics, and isn’t just about protest, it has to be around how do we reimagine and reclaim economics
  • markets actually belong to communities and people
  • capital wasn’t just an accumulated wealth for the rich
  • I think what we’re potentially  talking about here is to make the social economy hyper-productive, hyper-competitive, hyper-cooperative
  • The paradox is that capital already knows this. Capital is investing in these peer production projects
  • Part of the proposal of the FLOK society project in Ecuador will be to get that strategic reorganization to make the social economy strategic

What is an ontology and why we need it - 1 views

  • an ontology designer makes these decisions based on the structural properties of a class.
  • an ontology is a formal explicit description of concepts in a domain of discourse (classes (sometimes called concepts)), properties of each concept describing various features and attributes of the concept (slots (sometimes called roles or properties)), and restrictions on slots (facets (sometimes called role restrictions)). An ontology together with a set of individual instances of classes constitutes a knowledge base. In reality, there is a fine line where the ontology ends and the knowledge base begins.
  • Classes describe concepts in the domain
  • ...16 more annotations...
  • A class can have subclasses that represent concepts that are more specific than the superclass.
  • Here we discuss general issues to consider and offer one possible process for developing an ontology. We describe an iterative approach to ontology development: we start with a rough first pass at the ontology. We then revise and refine the evolving ontology and fill in the details. Along the way, we discuss the modeling decisions that a designer needs to make, as well as the pros, cons, and implications of different solutions.
  • In practical terms, developing an ontology includes: �         defining classes in the ontology, �         arranging the classes in a taxonomic (subclass–superclass) hierarchy, �         defining slots and describing allowed values for these slots, �         filling in the values for slots for instances.
  • We can then create a knowledge base by defining individual instances of these classes filling in specific slot value information and additional slot restrictions.
  • Slots describe properties of classes and instances:
  • some fundamental rules in ontology design
  • There is no one correct way to model a domain— there are always viable alternatives. The best solution almost always depends on the application that you have in mind and the extensions that you anticipate. 2)      Ontology development is necessarily an iterative process. 3)      Concepts in the ontology should be close to objects (physical or logical) and relationships in your domain of interest. These are most likely to be nouns (objects) or verbs (relationships) in sentences that describe your domain.
  • how detailed or general the ontology is going to be
  • what we are going to use the ontology for
  • concepts in the ontology must reflect this reality
  • We suggest starting the development of an ontology by defining its domain and scope. That is, answer several basic questions: �         What is the domain that the ontology will cover? �         For what  we are going to use the ontology? �         For what types of questions the information in the ontology should provide answers? �         Who will use and maintain the ontology?
  • plan to use
  • domain
  • If the people who will maintain the ontology describe the domain in a language that is different from the language of the ontology users, we may need to provide the mapping between the languages.
  • One of the ways to determine the scope of the ontology is to sketch a list of questions that a knowledge base based on the ontology should be able to answer, competency questions
  • These competency questions are just a sketch and do not need to be exhaustive.
