  • February 8, 2013 12:30 pm Amazon unpacked By Sarah O’Connor The online giant is creating thousands of UK jobs, so why are some employees less than happy?
  • Between a sooty power station and a brown canal on the edge of a small English town, there is a building that seems as if it should be somewhere else. An enormous long blue box, it looks like a smear of summer sky on the damp industrial landscape. Inside, hundreds of people in orange vests are pushing trolleys around a space the size of nine football pitches, glancing down at the screens of their handheld satnav computers for directions on where to walk next and what to pick up when they get there. They do not dawdle – the devices in their hands are also measuring their productivity in real time. They might each walk between seven and 15 miles today. It is almost Christmas and the people working in this building, together with those in seven others like it across the country, are dispatching a truck filled with parcels every three minutes or so. Before they can go home at the end of their eight-hour shift, or go to the canteen for their 30-minute break, they must walk through a set of airport-style security scanners to prove they are not stealing anything. They also walk past a life-sized cardboard image of a cheery blonde woman in an orange vest. “This is the best job I have ever had!” says a speech bubble near her head.
  • If you could slice the world in half right here, you could read the history of this town called Rugeley in the layers. Below the ground are the shafts and tunnels of the coal mine that fed the power station and was once the local economy’s beating heart. Above the ground are the trolleys and computers of Amazon, the global online retailer that has taken its place. As online shopping explodes in Britain, helping to push traditional retailers such as HMV out of business, more and more jobs are moving from high-street shops into warehouses like this one. Under pressure from politicians and the public over its tax arrangements, Amazon has tried to stress how many jobs it is creating across the country at a time of economic malaise. The undisputed behemoth of the online retail world has invested more than £1bn in its UK operations and announced last year that it would open another three warehouses over the next two years and create 2,000 more permanent jobs. Amazon even had a quote from David Cameron, the prime minister, in its September press release. “This is great news, not only for those individuals who will find work, but for the UK economy,” he said.

  • Workers in Amazon’s warehouses – or “associates in Amazon’s fulfilment centres” as the company would put it – are divided into four main groups. There are the people on the “receive lines” and the “pack lines”: they either unpack, check and scan every product arriving from around the world, or they pack up customers’ orders at the other end of the process. Another group stows away suppliers’ products somewhere in the warehouse. They put things wherever there’s a free space – in Rugeley, there are inflatable palm trees next to milk frothers and protein powder next to kettles. Only Amazon’s vast computer brain knows where everything is, because the workers use their handheld computers to scan both the item they are stowing away and a barcode on the spot on the shelf where they put it. The last group, the “pickers”, push trolleys around and pick out customers’ orders from the aisles. Amazon’s software calculates the most efficient walking route to collect all the items to fill a trolley, and then simply directs the worker from one shelf space to the next via instructions on the screen of the handheld satnav device. Even with these efficient routes, there’s a lot of walking. One of the new Rugeley “pickers” lost almost half a stone in his first three shifts. “You’re sort of like a robot, but in human form,” said the Amazon manager. “It’s human automation, if you like.” Amazon recently bought a robot company, but says it still expects to keep plenty of humans around because they are so much better at coping with the vast array of differently shaped products the company sells.
  • The unassuming efficiency of these warehouses is what enables Amazon to put parcels on customers’ doorsteps so quickly, even when it is receiving 35 orders a second. Every warehouse has its own “continuous improvement manager” who uses “kaizen” techniques pioneered by Japanese car company Toyota to improve prod­uctivity. Marc Onetto, the senior vice-president of worldwide operations, told a business school class at the University of Virginia a few years ago: “We use a bunch of Japanese guys, they are not consultants, they are insultants, they are really not nice … They’re samurais, the real last samurais, the guys from the Toyota plants.” In Rugeley, the person with the kaizen job is a friendly, bald man called Matt Pedersen, who has a “black belt” in “Six Sigma”, the Motorola-developed method of operational improvement, most famously embraced by Jack Welch at General Electric. Every day, the managers in Rugeley take a “genba walk”, which roughly means “go to the place” in Japanese, Pedersen says as he accompanies the FT on a tour of the warehouse. “We go to the associates and find out what’s stopping them from performing today, how we can make their day better.” Some people also patrol the warehouse pushing tall little desks on wheels with laptops on them – they are “mobile problem solvers” looking for any hitches that could be slowing down the operation.
  • . . . What did the people of Rugeley make of all this? For many, it has been a culture shock. “The feedback we’re getting is it’s like being in a slave camp,” said Brian Garner, the dapper chairman of the Lea Hall Miners Welfare Centre and Social Club, still a popular drinking spot. One of the first complaints to spread through the town was that employees were getting blisters from the safety boots some were given to wear, which workers said were either too cheap or the wrong sizes. One former shop-floor manager, who did not want to be named, said he always told new workers to smear their bare feet with Vaseline. “Then put your socks on and your boots on, because I know for a fact these boots are going to rub and cause blisters and sores.” ©Ben RobertsAmazon workers in Rugeley process ordersOthers found the pressure intense. Several former workers said the handheld computers, which look like clunky scientific calculators with handles and big screens, gave them a real-time indication of whether they were running behind or ahead of their target and by how much. Managers could also send text messages to these devices to tell workers to speed up, they said. “People were constantly warned about talking to one another by the management, who were keen to eliminate any form of time-wasting,” one former worker added.
  • Watson said Amazon was supposed to send the council employment data every six months, but it had not done so. “We had no idea Amazon were going to be as indifferent to these issues as they have been, it’s come as a shock to us how intransigent they are,” he said. Inside the warehouse, Amazon employees wear blue badges and the workers supplied by the agencies wear green badges. In the most basic roles they perform the same tasks as each other for the same pay of £6.20 an hour or so (the minimum adult wage is £6.19), but the Amazon workers also receive a pension and shares. A former agency worker said the prospect of winning a blue badge, “like a carrot, was dangled constantly in front of us by management in return for meeting shift targets”. Amazon’s Darwinian culture comes from the top. Jeff Bezos, its chief executive, told Forbes magazine last year (when it named him “number one CEO in America”): “Our culture is friendly and intense, but if push comes to shove, we’ll settle for intense.”
  • Ransdtad said it supplied a number of clients with “onsite-flexible workforce solutions”. It added: “The number of workers required by these clients fluctuates in response to supply and demand. When demand for clients’ products or services is high (for example during the Christmas period) the Randstad partnership allows local people to benefit from short-term work on a temporary contract, to help supplement our clients’ permanent workforce and deliver against order requirements.” Certainly, not everyone in Rugeley is upset about Amazon. A group of workers having a pint on a picnic table outside The Colliers pub near the warehouse gates said they liked their jobs, albeit as their managers hovered nervously in the background. One young agency worker said he was earning about £220 a week, compared with the £54 he had been receiving in jobless benefits. He had bought a car and moved out of his mum’s house and into a rented flat with his girlfriend, who he had met at work. “I’m doing pretty well for myself,” he said with a shy grin. “There’s always opportunities to improve yourself there.” Across the table, an older man, wagging two fingers with a cigarette pinched between them, said slowly: “It gives you your pride back, that’s what it gives you. Your pride back.” Many in the town, however, have mixed feelings. They are grateful for the jobs Amazon has created but they are also sad and angry about the quality of them. Timothy Jones, a barrister and parish councillor, summed up the mood. “I very much want them to stay, but equally I would like some of the worst employment practices to end.”
  • For Watson, the big question is whether these new jobs can support sustainable economic growth. In Rugeley, it is hard not to look back to the coal mine for an example of how one big employer could transform a place. . . . The Lea Hall Colliery opened officially on a soggy Tuesday in July 1960. Miners and their families huddled under marquees to eat their packed lunches and when the first coal was wound to the surface, three bands played an overture specially written for the occasion. It was the first mine planned and sunk by the Coal Board, the body set up after the second world war to run Britain’s newly nationalised coal industry, and the Central Electricity Generating Board was building a coal-fired power station right next door. It was a defiant demonstration of confidence in coal at a time of increasing competition from oil. “King Coal is not yet dead, as many would have it, but is going to be with us for many years to come,” the regional secretary of the National Union of Mineworkers told the crowd.
  • Soon, miners from all over the country were swarming to the modern new mine. The Coal Board and the local council built housing estates and schools to cope with the exploding population. “Peartree estate was built for the Geordies, the Springfield estate was built for the Scots and the Welsh,” remembered Brian Garner, who helped to build the mine when he was 16. “It was unbelievable, it was buzzing in the town, there was that much money about then. I could leave my job at 10 o’clock in the morning and start at five past 10 on another.” On Friday and Saturday nights, the queue outside the Lea Hall Miners’ Welfare Centre and Social Club would wrap right around the building. Rugeley’s mine was soon the most productive in the country. It was a “young man’s pit” with all the latest machines and techniques, says Ken Edwards, who started there at 25 as an electrician. The work was still dirty and dangerous, though. In 1972, a local reporter took a tour. “All is silent except for the movement of conveyor belts which carry the coal and the murmur of the air pumps. The blackness is relieved only by narrow shafts of light coming from each person’s headlamp,” she wrote. It took her two days to remove the black dust from her nails, ears, nose and hair.
  • The good times didn’t last. By the time the pit closed, four days before Christmas in 1990, a spokesman for British Coal told Reuters it was losing £300,000 a week. More than 800 people lost jobs that paid the equivalent of between £380 and £900 a week in today’s money. The town council’s chairman tried desperately to say something reassuring. “It has come as such a shock,” he told the local paper. “[But] we have got to do what many have done and look for new areas, particularly information technology and high technology. We have a lot of expertise and a wonderful geographical spot. There’s no reason why it should be the end for Rugeley.” From behind her desk in Vision estate agents, all purple paint and fairy lights, Dawn Goodwin sucks the air in through her teeth at the mention of Amazon. “We all thought it was going to be the making of the town,” she says. She expected an influx of people, including well-to-do managers, looking to buy or rent houses. But she hasn’t had any extra business at all. People are cautious because they don’t know how long their agency jobs with Amazon will last, she says. One of her tenants, a single young woman, got a job there but lost it again after she became ill halfway through a shift. She struggled to pay her rent for three months while she waited for her jobseeker’s benefits to be reinstated. “It’s leaving a bad taste in everyone’s mouths,” Goodwin says with a frown. Even the little “Unit 9” café next to the Amazon warehouse hasn’t had a boost in trade. The women who run it reckon the employees don’t have enough time in their 30-minute break to get through security, come and eat something, and then go back in again.
  • In a cramped upstairs office at the Citizens Advice Bureau, Gillian Astbury and Angela Jones have turned to statistics to try to identify Amazon’s effect on the area. They haven’t had an increase in the number of people asking about employment problems or unfair dismissal, but nor has there been any improvement in the community’s problems with debt and homelessness. Their best guess is that people haven’t had enough sustained work to make much of a difference. Astbury says employment agencies are a “necessary evil”, but stresses it is hardly ideal for people to be bouncing in and out of temporary work, particularly when a job ends abruptly and they are left with no income at all until their benefits are reinstated. Workers leaving Amazon have had a particular problem with this, prompting the parish council to submit a Freedom of Information request to the Department for Work and Pensions to find out exactly how long local people are being made to wait for their social security payments to come through.
  • Far from the CAB’s little office in Rugeley, Britain’s economists are also puzzling over why the economy remains moribund even though more and more people are in work. There are still about half a million fewer people working as full-time employees than there were before the 2008 crash, but the number of people in some sort of employment has surpassed the previous peak. Economists think the rise in insecure temporary, self-employed and part-time work, while a testament to the British labour market’s flexibility, helps to explain why economic growth remains elusive. Angi Cooney, who runs C Residential, the biggest estate agent in Rugeley, thinks the nature of employment is changing permanently and people should stop pining for the past. It’s “bloody great” that a company like Amazon chose to come to “this little old place”, she says fiercely, looking as if she’d like to take the town by the shoulders and give it a shake. “People expect a job for life, but the world isn’t like that any more, is it?” Sarah O’Connor is the FT’s economics correspondent

Firefox OS won't magically succeed just because it's open source - see webOS | Technolo... - 0 views

  • Firefox OS won't magically succeed just because it's open source - see webOS The siren song of open source means some people think Firefox OS could take the smartphone market by storm - but that's what they thought about webOS
  • Open source" operating systems are the siren call of the internet. For years, we were promised, Linux was going to be the Next Big Thing on the desktop; the tired old empires of Windows and MacOS were going to be pushed aside, and everyone was going to embrace Linux (though quite which distro wasn't clear). From infants to grannies, they would all see the light, and install software that was built with the user in mind - as long as the user was someone who could hold the idea of the concentric circles of file ownership (root/wheel/std) in their head
  • Despite the fevered imaginings of a fair number at the time, there was simply no chance that webOS was going to go anywhere without direct help from HP; and HP wasn't going to give it that help, since it had plenty of troubles of its own.
  • ...8 more annotations...
  • LG has indicated that it will be using webOS in its Smart TV line (which, in passing, suggests that Google's hopes of having a multi-manufacturer-pronged assault on the living room with Google TV are being chipped away; Samsung has gone its own way, Sony offers a mixture of Google and its own smart TV offerings, and now it looks like LG isn't exactly all-in). Though that might, in time, become something that it uses on phones or tablets, you'd be crazy to bet on it. LG is smart enough to know that TVs are a world away from phones and tablets, both in terms of the user interaction experience, and the demands that they make for user acceptance.
  • But the siren song of open source OSs becomes deafening when you look at the other announcement to come out of Mobile World Congress, in which Mozilla is touting its Firefox OS as the anathema to the world's ills - or at least those afflicting the smartphone industry. What does Moziila chief executive Gary Kovacs think is going to be the unique selling point of the Firefox OS phones that he expects to see in 2014? "Our goal is to level the playing field and usher in an explosion of content and services that will meet the diverse needs of the next two billion people online," he said in Barcelona, adding "We're not trying to get in the middle of an operating system fight; what we are trying to do is be the catalyst to drive more development around the open web."
  • The problem for Firefox OS is that it doesn't have a dedicated hardware backer. Sure, Sony has said that it will make some phones using it. ZTE and Alcatel say they will build hardware that will run it. And Kovacs points to the fact that Firefox OS will run HTML5 apps - not "native" apps (in the sense that iOS or Android apps run natively). That might put a questionmark over whether, by some analysts' measure, the FFOS phone is truly a "smartphone", since their definition for that includes "running apps on a native API". (That's why Gartner and IDC don't class Nokia's Asha phones as smartphones.)
  • So how did Android succeed? Three things. First, Google get a vibrant app ecosystem going even before there was a single phone: it had competitions for apps, with a $10m fund to seed developer ideas. By April 2008 there were almost 2,000 Android applications; two-third came from outside the US. Among the offerings: photo-enhanced driving, on-the-fly party mashups with maps, maintaining passive surveillance on your family's whereabouts. (Some things never change.) Second, it was able to go to Verizon, which was looking enviously at how AT&T was able to offer the iPhone, and suggest that Android phones - when they came along - could be the answer to that competitive challenge. And third, it was Google - the gigantic search-engine-and-everything-else company with the international reputation. If Google was doing a new generation of smartphone software (and if Apple had validated the idea), then it looked like a good deal for everyone. And handset manufacturers were eager to find an alternative to Microsoft.
  • Android is gigantic - some version of it might be on a billion phones this year - meaning there's no obvious need for another open source OS. What, after all, is FFOS actually going to do that Android doesn't, or that iOS or Windows Phone or BlackBerry can't? Yes, we've heard that the target isn't the west, but the developing world; that still doesn't explain why a Chinese handset manufacturer would deploy FFOS rather than Android, whether the Google version or a forked one that could connect to a local app store.
  • Even worse, FFOS is at an immediate competitive disadvantage because the principal browser on smartphones now is based on WebKit. Chrome uses it, MobileSafari uses it, BlackBerry uses it, and Opera uses it too now. That leaves only Internet Explorer on Windows Phone standing alone. Developers writing HTML5 apps will naturally write for compatibility with WebKit, which is always going to behave slightly differently from Firefox's Gecko rendering engine. For FFOS's sake, you have to hope the differences aren't big.
  • That's the trouble with the magical thinking that often attaches to open source projects. Making webOS open source didn't solve its problems; it simply shoved them off into a siding. Having an open source mobile OS didn't guarantee Android's success; the efforts of Google, and the timing in the market, did that.
  • Perhaps for that reason, people have high expectations for the Ubuntu OS and phone, with its fabulously complex array of gestures for control. Bad news, dreamers: it's going to fail in the market too if Canonical attempts to market it as a hardware-software combination - that is, sells Ubuntu phones at retail.

BBC News - Web code weakness allows data dump on PCs - 0 views

clevercode html5 browser bug

shared by Gabrijela Vrbnjak on 04 Mar 13 - No Cached
  • The loophole exploits a feature of HTML 5 which defines how websites are made and what they can do.
  • Developer Feross Aboukhadijeh found the bug and set up a demo page that fills visitors' hard drives with pictures of cartoon cats. In one demo, Mr Aboukhadijeh managed to dump one gigabyte of data every 16 seconds onto a vulnerable Macbook. Clever code Most major browsers, Chrome, Internet Explorer, Opera and Safari, were found to be vulnerable to the bug, said Mr Aboukhadijeh. While most websites are currently built using version 4 of the Hyper Text Markup Language (HTML), that code is gradually being superseded by the newer version 5. One big change brought in with HTML 5 lets websites store more data locally on visitors' PCs. Safeguards built into the "local storage" specification should limit how much data can be stored. Different browsers allow different limits but all allow at least 2.5 megabytes to be stored. However, Mr Aboukhadijeh found a way round this cap by creating lots of temporary websites linked to the one a person actually visited. He found that each one of these associated sites was allowed to store up to the limit of data because browser makers had not written code to stop this happening. By endlessly creating new, linked websites the bug can be used to siphon huge amounts of data onto target PCs. Only Mozilla's Firefox capped storage at 5MB and was not vulnerable, he found. "Cleverly coded websites have effectively unlimited storage space on visitor's computers," wrote Mr Aboukhadijeh in a blogpost about the bug. Code to exploit the bug has been released by Mr Aboukhadijeh and he set up a website, called Filldisk that, on vulnerable PCs, dumps lots of images of cats on to the hard drive. So far, no malicious use of the exploits has been observed. In a bid to solve the problem, bug reports about the exploit have been filed with major browser makers.

  • ...5 more annotations...
  • Instead of buying huge amounts of computing power and storage that may be unused for most of the year, companies can get what they need in a more flexible way.
  • IBM has allotted enough computing resources to cope with the surge during the tournament.
  • Cloud computing has another useful feature. Instead of being locked into long contracts, firms can buy their IT over much shorter time frames. It can even be metered. This is extremely useful for companies that are launching one-off projects or perhaps start-up firms that are not sure how successful they are going to be. Extra capacity can be bought online and paid for as needed. Zoopla is a UK property website which allows users to search for homes.
  • Zoopla uses Amazon Web Services (AWS), which launched in 2006 and is the biggest player in cloud computing.
  • Analysts at Tier1 Research estimate that just 2% of total spending on information technology is on cloud services. Daniel Beazer, a hosting and cloud analyst at Tier1 Research, said: "Most companies have been around for a lot longer than the internet and have systems that are decades old." "Mostly what they have works, just about, so why bother shifting it? The savings from virtualisation and the cloud aren't currently big enough to justify it," he said.

  • I would like my browsing and Google searches to be private. I don't want targeted advertising and I don't want to feel that anonymous companies are harvesting my clicks to learn all about me.
  • When the web was young, and a lot less shiny, web pages were fixed (static) and – barring browser quirks – everybody saw much the same thing. Today, much of the web is dynamic, which means that what you see has been adapted or possibly constructed on the fly just for you.
  • From your point of view, the advantage is that the websites you visit will be personalised to suit your needs and tastes. From the website's point of view, the advantage is that it can also personalise its prices and advertising to try to suit your needs and tastes, and increase your propensity to click and buy.
  • ...6 more annotations...
  • On the web, the rule is: if you're not paying, then you are what's being sold.
  • Probably the simplest way to reduce personalisation is to use an anonymising service. Instead of accessing the web directly, you access it via a third-party proxy server, so your that requests are mixed in with thousands of others. These services usually allow you to control cookies, turn JavaScript on and off, withhold "referrer details" and so on.
  • Nonetheless, it's often useful to have access to an anonymous proxy service, and everybody should find one they like. Examples include The Cloak, Megaproxy, Proxify and ID Zap. There are also networked open source privacy systems such as Tor and I2P.
  • Google also tracks your progress across hundreds of thousands of websites via Google Analytics. To opt out of this, install the Google Analytics Opt-out Browser Add-on (Beta), which Google offers for Microsoft Internet Explorer, Google Chrome, Mozilla Firefox, Apple Safari and Opera. However, some sites use different analytics software or track visitors in other ways you will be unaware of. Ghostery may help reduce these.
  • Finally, Facebook Connect is a potential privacy problem because it "allows users to 'connect' their Facebook identity, friends and privacy to any site".
  • In general, the more you do online – social networking, cloud computing etc – the more your privacy and security are at risk. Reducing that risk involves effort and inconvenience, so it's up to you to find an acceptable compromise

  • Every time you read a newspaper on your computer or buy an ebook, you can leave an electronic trail behind you. That trail is potentially lucrative for business, and is a new source of surveillance for government and law enforcement.
  • Retailers and search engines, most notably Amazon and Google, can now gather an astonishingly detailed portrait of our book-reading habits: what we buy, what we browse, the amount of time we spend on a page and even the annotations we make in an ebook.
  • Amazon also reserves the right to disclose information when it "believes release is appropriate to comply with the law". A stronger protection for our privacy should require a warrant before personal data is released.

Judging by the fervor of the anti-SOPA/PIPA protests, a casual observer might think the advocates of the anti-piracy bills were in the same moral league as the torturers at Abu Ghraib.
  • But before we celebrate this “populist” victory, it’s worth remembering that the defeat of SOPA and PIPA was also a victory for the enormously powerful tech industry, which almost always beats the far smaller creative businesses in legislative disputes. (Google alone generated more than $37 billion in 2011, more than double the revenue of all record companies, major and indie combined.)
  • One example of anti-SOPA rhetorical over-reach was a tendency by some to invent sinister motives for the sponsors. On his usually brilliant show The Young Turks, Uygur said that SOPA’s sponsors were “pushing for a monopoly for the MPAA and to kill their competition on the Internet.” This is untrue. They wanted to kill those entities that steal their movies and make money off them, either directly or indirectly. There really is a difference

  • The hundreds of thousands of apps, available in just a few years, originate from the intersection of two factors:
  • The desire and necessity to have simple, functional and fast devices able to do specific tasks on the go.
  • the operative skills to develop apps for popular mobile platforms such as Iphone Operating System (IOS) or Google Android. 
  • Apps galore
  • Apple likes to play on the ambiguity in a form of propaganda that exalts the “revolutionary” spirit of technological innovation
  • The first iPhone, in 2007, inaugurated the new phase of the cognitive era, just as the PC heralded the decline of the industrial phase. Five years later, Apple no longer has a monopoly: hundreds of millions of smartphones and tablets are sold every year and the total number of these active devices will be soon 2 billion. It took the PC thirty years to reach this level of diffusion.

  • Often these machines play opposite functions: as a tool to create new forms of horizontal communication and social interaction or as bait for a capillary exploitation.
  • A political analysis of mobile devices
  • The PC became a liberating tool for social cooperation in the workplace of a booming third-sector.
  • In the following phase, the spread of the first mobile devices – cellphones and laptops – provided an initial impulse for a blurring of life and work, imposing with mobile calls, emails or SMS a new type of real-time processing, regulating the rhythms of life
  • In the new biohypermedia environment, the key change lies in the combination of miniaturizing and mobilizing these pieces of equipment, allowing them to always be within the body’s reach in any context.
  • they augment physical reality[ix] with every kind of information – commercial, cultural, ecological – and act more and more as biomedical sets for the control, correction and support of our vital biological functions.
  • The PC has a central function as the medium for linguistic and written processes - its typical uses often tied to the logical concatenation of thought and the priority management of sequences over time.
  • But mobile devices concentrate complex perception of stimuli in terms of spatial organization and intervene in emotional responses. PC work in this way occupies our left hemisphere, while the continual interactions of a smartphone engage the right hemisphere.
  • In contemporary neoliberalism, these devices become an essential means of rent and profit, through a fine capture of what we generate by living with them and using them. At one and the same time technocracy and financial oligarchies find here an ideal medium to extend their influence and their control of individuals in space and time.
  • Marketing and communication campaigns portray these devices as commodity fetishes, characterizing a new phase of capitalism often described as cognitive because based on knowledge.
  • In the sphere of multinational ICT[x] Corporations a war is being waged over the design and deployment of immaterial enclosures
  • Even though all this is based on freeware and open source, they trick us into believing that the iPhone 5, Windows 8 or Jellybean[xi] are miracles that descend from Mount Olympus and for which we should be grateful as to the gods.
  • Unlike automobiles or, to a lesser degree, PCs, the use value of new mobile devices is no longer determined merely by the initial design but can be moulded by the final user.
  • The innumerable websites, blogs and forums in every language globally blooming and growing are a workshop for worldwide exchange where the digital means are developed that could be used to withdraw workers both from precarity and  from total submission to a life of labour.  
  • Microsoft is no less defensive of its monopoly: with Intel and other accomplices, they introduced a new firmware to boot Windows 8 PCs that, substituting the old BIOS,[xv] makes it impossible or very complicated to install Linux or other operating systems on new laptops.
  • Despite hesitations related to “security” problems, today companies allow or even oblige people to use their own devices
  • So, if you were one of those many who found the latest tablet, smartphone or hybrid touch device under the tree this year, be aware that you won’t be the only one pleased: under the regime of precarity, bring your own device if you want to survive.
