Tip: Use the new microformats API in your Firefox 3.0 Extensions - 0 views

  • The upcoming Firefox 3.0 release has built-in support for microformats in the form of an API that you can access from a Firefox extension. In this tip, you follow a simple example of how to use this API from within your extension code. You take a skeleton Hello World extension and give it the ability to store an hCard from any Web page and then use that stored hCard to populate a Web form.

10 important tips for living a multi-platform life | CITEworld - 0 views

  •  
    "With the rise of different mobile platforms and content ecosystems over the past decade, the technology world is becoming increasingly fragmented. Fifteen years ago, there were only a handful of platforms that mattered -- Windows PCs, Macs, and perhaps Linux on the desktop, and primarily BlackBerry in the mobile space. Today, the number is far greater -- Windows (further divided into the pre- and post-Windows 8 offerings), OS X, Linux, Chrome OS, Android (in many varying incarnations), iOS, Windows Phone, BlackBerry, Amazon's Kindle and Fire products, to name the most common. Each of these platforms has become increasingly insular, making lock-in to a specific vendor, device, or OS much more common.  Featured Resource Presented by Citrix Systems 10 essential elements for a secure enterprise mobility strategy Best practices for protecting sensitive business information while making people productive from LEARN MORE Although it is possible to switch from an iPhone to Android, or from Windows to Mac, there is often a trade-off in making the switch. Apps, music, ebooks, and other content may need to be re-purchased. There will likely be some learning curve. The offerings in the new ecosystem -- apps or content -- may not match the experience to which we've become accustomed, and some may not be available at all.  Here's some guidance on how to switch platforms."

BitTorrent Sync creates private, peer-to-peer Dropbox, no cloud required | Ars Technica - 6 views

  • BitTorrent today released folder syncing software that replicates files across multiple computers using the same peer-to-peer file sharing technology that powers BitTorrent clients. The free BitTorrent Sync application is labeled as being in the alpha stage, so it's not necessarily ready for prime-time, but it is publicly available for download and working as advertised on my home network. BitTorrent, Inc. (yes, there is a legitimate company behind BitTorrent) took to its blog to announce the move from a pre-alpha, private program to the publicly available alpha. Additions since the private alpha include one-way synchronization, one-time secrets for sharing files with a friend or colleague, and the ability to exclude specific files and directories.
  • BitTorrent Sync provides "unlimited, secure file-syncing," the company said. "You can use it for remote backup. Or, you can use it to transfer large folders of personal media between users and machines; editors and collaborators. It’s simple. It’s free. It’s the awesome power of P2P, applied to file-syncing." File transfers are encrypted, with private information never being stored on an external server or in the "cloud." "Since Sync is based on P2P and doesn’t require a pit-stop in the cloud, you can transfer files at the maximum speed supported by your network," BitTorrent said. "BitTorrent Sync is specifically designed to handle large files, so you can sync original, high quality, uncompressed files."
  •  
    Direct P2P encrypted file syncing, no cloud intermediate, which should translate to far more secure exchange of files, with less opportunity for snooping by governments or others, than with cloud-based services.

    Hey Paul, is there an open source document management system that I could hook the BitTorrent Sync to?
  •  
    More detail please. What do you want to do with the doc management system? Platform? Server-side or stand-alone? Industrial strength and highly configurable or lightweight and simple? What do you mean by "hook?" Not that I would be able to answer anyway. I really know very little about BitTorrent Sync. In fact, as far as I'd gone before your question was to look at the FAQ. It's linked from . But there's a link to a forum on the same page. Giving the first page a quick scan confirms that this really is alpha-state software. But that would probably be a better place to ask. (Just give them more specific information of what you'd like to do.) There are other projects out there working on getting around the surveillance problem. I2P is one that is a farther along than BitTorrent Sync and quite a bit more flexible. See . (But I haven't used it, so caveat emptor.)
  •  
    There is a great list of PRISM Proof software at http://prism-break.org/. Includes a link to I2P. I want to replace gmail though, but would like another Web based system since I need multi device access. Of course, I need to replace my Google Apps / Google Docs system. That's why I asked about a PRISM Proof sync-share-store DMS. My guess is that there are many users similarly seeking a PRISM Proof platform of communications, content and collaborative computing systems. BusinessIndiser.com is crushed with articles about Google struggling to squirm out from under the NSA PRISM boot-on-the-back-of-their-neck situation. As if blaming the NSA makes up for the dragnet that they consented/allowed/conceded to cover their entire platform. Perhaps we should be watching Germany? There must be tons of startup operations underway, all seeking to replace Google, Amazon, FaceBook, Microsoft, Skype and so many others. It's a great day for Libertyware :)
  •  
    Is the NSA involvement the "Kiss of Death"? Google seems to think so. I'm wondering what the impact would be if ZOHO were to announce a PRISM Proof productivity platform?
  •  
    It is indeed. The E.U. has far more protective digital privacy rights than we do (none). If you're looking for a Dropbox replacement (you should be), for a cloud-based solution take a look at . Unlike Dropbox, all of the encryption/decryption happens on your local machine; Wuala never sees your files unencrypted. Dropbox folks have admitted that there's no technical barrier to them looking at your files. Their encrypt/decrypt operations are done in the cloud (if they actually bother) and they have the key. Which makes it more chilling that the PRISM docs Snowden link make reference to Dropbox being the next cloud service NSA plans to add to their collection. Wuala also is located (as are its servers) in Switzerland, which also has far stronger digital data privacy laws than the U.S. Plus the Swiss are well along the path to E.U. membership; they've ratified many of the E.U. treaties including the treaty on Human Rights, which as I recall is where the digital privacy sections are. I've begun to migrate from Dropbox to Wuala. It seems to be neck and neck with Dropbox on features and supported platforms, with the advantage of a far more secure approach and 5 GB free. But I'd also love to see more approaches akin to IP2 and Bittorrent Sync that provide the means to bypass the cloud. Don't depend on government to ensure digital privacy, route around the government voyeurs. Hmmm ... I wonder if the NSA has the computer capacity to handle millions of people switching to encrypted communication? :-) Thanks for the link to the software list.

    Re: Google. I don't know if it's the 'kiss of death" but they're definitely going to take a hit, particularly outside the U.S. BTW, I'm remembering from a few years back when the ODF Foundation was still kicking. I did a fair bit of research on the bureaucratic forces in the E.U. that were pushing for the Open Document Exchange Formats. That grew out of a then-ongoing push to get all of the E.U. nations connected via a network that is not dependent on the Internet. It was fairly complete at the time down to the national level and was branching out to the local level and the plan from there was to push connections to business and then to Joe Sixpack and wife. Interop was key, hence ODEF. The E.U. might not be that far away from an ability to sever the digital connections with the U.S. Say a bunch of daisy-chained proxy anonymizers for communications with the U.S. Of course they'd have to block the UK from the network and treat it like it is the U.S. There's a formal signals intelligence service collaboration/integration dating back to WW 2, as I recall, among the U.S., the U.K., Canada, Australia, and New Zealand. Don't remember its name. But it's the same group of nations that were collaborating on Echelon. So the E.U. wouldn't want to let the UK fox inside their new chicken coop. Ah, it's just a fantasy. The U.S. and the E.U. are too interdependent. I have no idea hard it would be for the Zoho folk to come up with desktop/side encryption/decryption. And I don't know whether their servers are located outside the reach of a U.S. court's search warrant. But I think Google is going to have to move in that direction fast if it wants to minimize the damage. Or get way out in front of the hounds chomping at the NSA's ankles and reduce the NSA to compost. OTOH, Google might be a government covert op. for all I know. :-) I'm really enjoying watching the NSA show. Who knows what facet of their Big Brother operation gets revealed next?

    ZOHO is an Indian company with USA marketing offices. No idea where the server farm is located, but they were not on the NSA list. I've known Raju Vegesna for years, mostly from the old Web 2.0 and Office 2.0 Conferences. Raju runs the USA offices in Santa Clara. I'll try to catch up with him on Thursday. How he could miss this once in a lifetime moment to clean out Google, Microsoft and SalesForce.com is something I'd like to find out about. Thanks for the Wuala tip. You sent me that years ago, when i was working on research and design for the SurDocs project. Incredible that all our notes, research, designs and correspondence was left to rot in Google Wave! Too too funny. I recall telling Alex from SurDocs that he had to use a USA host, like Amazon, that could be trusted by USA customers to keep their docs safe and secure. Now look what i've done! I've tossed his entire company information set into the laps of the NSA and their cabal of connected corporatists :)

IPhone software developers stifled under Apple's gag order - Los Angeles Times - 0 views

  • The software development kit that Apple Inc. distributed to programmers bound them to not discuss the process of creating programs for the iPhone. Companies typically waive such legal restrictions once the product in question launches, but Apple didn't. And it won't say why.
  • As a result, iPhone developers -- and businesses that cater to them -- say they are prohibited from asking technical questions or sharing tips anywhere in public. On Apple's official support website, moderators remind visitors that they are bound by the nondisclosure agreement and should mind what they say or ask.
  • Conference organizers are trying to figure out how to plan sessions for iPhone software developers when they're not allowed to talk about iPhone software. Book publishers are sitting on how-to manuals, afraid that if they ship them Apple will sue.

UN Report Finds Mass Surveillance Violates International Treaties and Privacy Rights - ... - 0 views

  • The United Nations’ top official for counter-terrorism and human rights (known as the “Special Rapporteur”) issued a formal report to the U.N. General Assembly today that condemns mass electronic surveillance as a clear violation of core privacy rights guaranteed by multiple treaties and conventions. “The hard truth is that the use of mass surveillance technology effectively does away with the right to privacy of communications on the Internet altogether,” the report concluded. Central to the Rapporteur’s findings is the distinction between “targeted surveillance” — which “depend[s] upon the existence of prior suspicion of the targeted individual or organization” — and “mass surveillance,” whereby “states with high levels of Internet penetration can [] gain access to the telephone and e-mail content of an effectively unlimited number of users and maintain an overview of Internet activity associated with particular websites.” In a system of “mass surveillance,” the report explained, “all of this is possible without any prior suspicion related to a specific individual or organization. The communications of literally every Internet user are potentially open for inspection by intelligence and law enforcement agencies in the States concerned.”
  • Mass surveillance thus “amounts to a systematic interference with the right to respect for the privacy of communications,” it declared. As a result, “it is incompatible with existing concepts of privacy for States to collect all communications or metadata all the time indiscriminately.” In concluding that mass surveillance impinges core privacy rights, the report was primarily focused on the International Covenant on Civil and Political Rights, a treaty enacted by the General Assembly in 1966, to which all of the members of the “Five Eyes” alliance are signatories. The U.S. ratified the treaty in 1992, albeit with various reservations that allowed for the continuation of the death penalty and which rendered its domestic law supreme. With the exception of the U.S.’s Persian Gulf allies (Saudi Arabia, UAE and Qatar), virtually every major country has signed the treaty. Article 17 of the Covenant guarantees the right of privacy, the defining protection of which, the report explained, is “that individuals have the right to share information and ideas with one another without interference by the State, secure in the knowledge that their communication will reach and be read by the intended recipients alone.”
  • The report’s key conclusion is that this core right is impinged by mass surveillance programs: “Bulk access technology is indiscriminately corrosive of online privacy and impinges on the very essence of the right guaranteed by article 17. In the absence of a formal derogation from States’ obligations under the Covenant, these programs pose a direct and ongoing challenge to an established norm of international law.” The report recognized that protecting citizens from terrorism attacks is a vital duty of every state, and that the right of privacy is not absolute, as it can be compromised when doing so is “necessary” to serve “compelling” purposes. It noted: “There may be a compelling counter-terrorism justification for the radical re-evaluation of Internet privacy rights that these practices necessitate. ” But the report was adamant that no such justifications have ever been demonstrated by any member state using mass surveillance: “The States engaging in mass surveillance have so far failed to provide a detailed and evidence-based public justification for its necessity, and almost no States have enacted explicit domestic legislation to authorize its use.”
  • ...5 more annotations...
  • Instead, explained the Rapporteur, states have relied on vague claims whose validity cannot be assessed because of the secrecy behind which these programs are hidden: “The arguments in favor of a complete abrogation of the right to privacy on the Internet have not been made publicly by the States concerned or subjected to informed scrutiny and debate.” About the ongoing secrecy surrounding the programs, the report explained that “states deploying this technology retain a monopoly of information about its impact,” which is “a form of conceptual censorship … that precludes informed debate.” A June report from the High Commissioner for Human Rights similarly noted “the disturbing lack of governmental transparency associated with surveillance policies, laws and practices, which hinders any effort to assess their coherence with international human rights law and to ensure accountability.” The rejection of the “terrorism” justification for mass surveillance as devoid of evidence echoes virtually every other formal investigation into these programs. A federal judge last December found that the U.S. Government was unable to “cite a single case in which analysis of the NSA’s bulk metadata collection actually stopped an imminent terrorist attack.” Later that month, President Obama’s own Review Group on Intelligence and Communications Technologies concluded that mass surveillance “was not essential to preventing attacks” and information used to detect plots “could readily have been obtained in a timely manner using conventional [court] orders.”
  • That principle — that the right of internet privacy belongs to all individuals, not just Americans — was invoked by NSA whistleblower Edward Snowden when he explained in a June, 2013 interview at The Guardian why he disclosed documents showing global surveillance rather than just the surveillance of Americans: “More fundamentally, the ‘US Persons’ protection in general is a distraction from the power and danger of this system. Suspicionless surveillance does not become okay simply because it’s only victimizing 95% of the world instead of 100%.” The U.N. Rapporteur was clear that these systematic privacy violations are the result of a union between governments and tech corporations: “States increasingly rely on the private sector to facilitate digital surveillance. This is not confined to the enactment of mandatory data retention legislation. Corporates [sic] have also been directly complicit in operationalizing bulk access technology through the design of communications infrastructure that facilitates mass surveillance. ”
  • The report was most scathing in its rejection of a key argument often made by American defenders of the NSA: that mass surveillance is justified because Americans are given special protections (the requirement of a FISA court order for targeted surveillance) which non-Americans (95% of the world) do not enjoy. Not only does this scheme fail to render mass surveillance legal, but it itself constitutes a separate violation of international treaties (emphasis added): The Special Rapporteur concurs with the High Commissioner for Human Rights that where States penetrate infrastructure located outside their territorial jurisdiction, they remain bound by their obligations under the Covenant. Moreover, article 26 of the Covenant prohibits discrimination on grounds of, inter alia, nationality and citizenship. The Special Rapporteur thus considers that States are legally obliged to afford the same privacy protection for nationals and non-nationals and for those within and outside their jurisdiction. Asymmetrical privacy protection regimes are a clear violation of the requirements of the Covenant.
  • Three Democratic Senators on the Senate Intelligence Committee wrote in The New York Times that “the usefulness of the bulk collection program has been greatly exaggerated” and “we have yet to see any proof that it provides real, unique value in protecting national security.” A study by the centrist New America Foundation found that mass metadata collection “has had no discernible impact on preventing acts of terrorism” and, where plots were disrupted, “traditional law enforcement and investigative methods provided the tip or evidence to initiate the case.” It labeled the NSA’s claims to the contrary as “overblown and even misleading.” While worthless in counter-terrorism policies, the UN report warned that allowing mass surveillance to persist with no transparency creates “an ever present danger of ‘purpose creep,’ by which measures justified on counter-terrorism grounds are made available for use by public authorities for much less weighty public interest purposes.” Citing the UK as one example, the report warned that, already, “a wide range of public bodies have access to communications data, for a wide variety of purposes, often without judicial authorization or meaningful independent oversight.”
  • The latest finding adds to the growing number of international formal rulings that the mass surveillance programs of the U.S. and its partners are illegal. In January, the European parliament’s civil liberties committee condemned such programs in “the strongest possible terms.” In April, the European Court of Justice ruled that European legislation on data retention contravened EU privacy rights. A top secret memo from the GCHQ, published last year by The Guardian, explicitly stated that one key reason for concealing these programs was fear of a “damaging public debate” and specifically “legal challenges against the current regime.” The report ended with a call for far greater transparency along with new protections for privacy in the digital age. Continuation of the status quo, it warned, imposes “a risk that systematic interference with the security of digital communications will continue to proliferate without any serious consideration being given to the implications of the wholesale abandonment of the right to online privacy.” The urgency of these reforms is underscored, explained the Rapporteur, by a conclusion of the United States Privacy and Civil Liberties Oversight Board that “permitting the government to routinely collect the calling records of the entire nation fundamentally shifts the balance of power between the state and its citizens.”

Google Says Website Encryption Will Now Influence Search Rankings - 0 views

  • Google will begin using website encryption, or HTTPS, as a ranking signal – a move which should prompt website developers who have dragged their heels on increased security measures, or who debated whether their website was “important” enough to require encryption, to make a change. Initially, HTTPS will only be a lightweight signal, affecting fewer than 1% of global queries, says Google. That means that the new signal won’t carry as much weight as other factors, including the quality of the content, the search giant noted, as Google means to give webmasters time to make the switch to HTTPS. Over time, however, encryption’s effect on search ranking make strengthen, as the company places more importance on website security. Google also promises to publish a series of best practices around TLS (HTTPS, is also known as HTTP over TLS, or Transport Layer Security) so website developers can better understand what they need to do in order to implement the technology and what mistakes they should avoid. These tips will include things like what certificate type is needed, how to use relative URLs for resources on the same secure domain, best practices around allowing for site indexing, and more.
  • In addition, website developers can test their current HTTPS-enabled website using the Qualys Lab tool, says Google, and can direct further questions to Google’s Webmaster Help Forums where the company is already in active discussions with the broader community. The announcement has drawn a lot of feedback from website developers and those in the SEO industry – for instance, Google’s own blog post on the matter, shared in the early morning hours on Thursday, is already nearing 1,000 comments. For the most part, the community seems to support the change, or at least acknowledge that they felt that something like this was in the works and are not surprised. Google itself has been making moves to better securing its own traffic in recent months, which have included encrypting traffic between its own servers. Gmail now always uses an encrypted HTTPS connection which keeps mail from being snooped on as it moves from a consumer’s machine to Google’s data centers.
  • While HTTPS and site encryption have been a best practice in the security community for years, the revelation that the NSA has been tapping the cables, so to speak, to mine user information directly has prompted many technology companies to consider increasing their own security measures, too. Yahoo, for example, also announced in November its plans to encrypt its data center traffic. Now Google is helping to push the rest of the web to do the same.
  •  
    The Internet continues to harden in the wake of the NSA revelations. This is a nice nudge by Google.

Duke Engines' incredibly compact, lightweight valveless axial engine - 0 views

  • The Duke engine is an axial design, meaning that its five cylinders encircle the drive shaft and run parallel with it. The pistons drive a star-shaped reciprocator, which nutates around the drive shaft, kind of like a spinning coin coming to rest on a table.
  • The reciprocator's center point is used to drive the central drive shaft, which rotates in the opposite direction to the reciprocator. "That counter-rotation keeps it in tidy balance," says Duke co-founder John Garvey. "If you lay your hand on it while it's running, you can barely detect any motion at all, it's quite remarkable." That's borne out by the video below, where the engine revving doesn't even cause enough vibrations to tip a coin off its side.
  • Instead of cam- or pneumatically-operated intake and outlet valves, the cylinders rotate past intake and outlet ports in a stationary head ring. The spark plugs are also mounted in this stationary ring – the cylinders simply slide past each port or plug at the stage of the cycle it's needed for and move on. In this way, Duke eliminates all the complexity of valve operation and manages to run a five-cylinder engine with just three spark plugs and three fuel injectors. The Duke engine ends up delivering as many power strokes per revolution as a six cylinder engine, but with huge weight savings and a vast reduction in the number of engine parts.
  • ...1 more annotation...
  • The engine has shown excellent resistance to pre-ignition (or detonation) – potentially because its cylinders tend to run cooler than comparable engines. Duke has run compression ratios as high as 14:1 with regular 91-octane gasoline. This suggests that further developments will pull even more power out of a given amount of fuel, increasing the overall efficiency of the unit.
  •  
    Watch the second video! This is extraordinary. "New Zealand's Duke Engines has been busy developing and demonstrating excellent results with a bizarre axial engine prototype that completely does away with valves, while delivering excellent power and torque from an engine much smaller, lighter and simpler than the existing technology. We spoke with Duke co-founder John Garvey to find out how the Duke Axial Engine project is going."

How to Protect Yourself from NSA Attacks on 1024-bit DH | Electronic Frontier Foundation - 0 views

  • In a post on Wednesday, researchers Alex Halderman and Nadia Heninger presented compelling research suggesting that the NSA has developed the capability to decrypt a large number of HTTPS, SSH, and VPN connections using an attack on common implementations of the Diffie-Hellman key exchange algorithm with 1024-bit primes. Earlier in the year, they were part of a research group that published a study of the Logjam attack, which leveraged overlooked and outdated code to enforce "export-grade" (downgraded, 512-bit) parameters for Diffie-Hellman. By performing a cost analysis of the algorithm with stronger 1024-bit parameters and comparing that with what we know of the NSA "black budget" (and reading between the lines of several leaked documents about NSA interception capabilities) they concluded that it's likely NSA has been breaking 1024-bit Diffie-Hellman for some time now. The good news is, in the time since this research was originally published, the major browser vendors (IE, Chrome, and Firefox) have removed support for 512-bit Diffie-Hellman, addressing the biggest vulnerability. However, 1024-bit Diffie-Hellman remains supported for the forseeable future despite its vulnerability to NSA surveillance.
