$2,400 “Introduction to Linux” course will be free and online this summerThe Linux Foundation is putting its training materials up on edX's platform.
by Megan Geuss - Mar 8 2014, 10:00pm CET
Earlier this week, The Linux Foundation announced that it would be working with edX, a non-profit online learning site governed by Harvard and MIT, to make its “Introduction to Linux” course free and open to all.
The Linux Foundation has long offered a wide variety of training courses through its website, but those can generally cost upwards of $2,000. This introductory class, which usually costs $2,400, will be the first from the Linux Foundation to run as a Massive Open Online Course (MOOC). There is no limit on enrollment through edX's platform.
The course will be held this summer, although an official start date has not been posted yet. Jennifer Cloer, Director of Communications for the Linux Foundation, said that over 2,500 people signed up for the course within the first 24 hours of it being posted. There are no prerequisites, and a note on the course's information page says that most users will find the course takes between 40 and 60 hours to complete.
Students can either audit the course, which means they'd get access to all the course materials but not have to commit to completing the tests and assignments, or they can take the course for a certificate of completion, which will be offered for free. (On some edX classes, "verified certificates of achievement" cost a fee.)
If all goes smoothly, the Linux Foundation may consider making more courses available on edX in the future.
In the press release from the Linux Foundation, executive director Jim Zemlin wrote, “Our mission is to advance Linux and that includes ensuring we have a talent pool of Linux professionals. To widen that talent pool and give more people access to the opportunities in the Linux community and IT industry, we are making our training program more accessible to users worldwide.”

These friends are smart people, and if they’re not convinced about Git, the problem is not them; it’s that they haven’t seen the right argument yet. There’s so much content out there about Git, and much of it is written at a level that’s way higher than my expertise. But in a way, that’s an issue. When you’re first starting out learning something, the questions that you have are way different from the questions an experienced person has. Once you’ve won that knowledge, it’s almost impossible to go back and think about what it was like when you were first learning. That puts you in a bad position to explain to someone else who’s brand new.
Git seems particularly prone to this because it’s based on some pretty complex notions of how to think about version control. In particular, once you internalize the concept of the Directed Acyclic Graph (DAG) that underlies basically everything in Git, you tend to want to explain that to new people because (a) it can help you think about how Git works; and (b) it’s cool. Unfortunately, teaching Git from a DAG perspective is IMHO the worst way to teach it to new users because it suggests to them that they have to thoroughly understand complex concepts from graph theory to use Git effectively. There’s also no question that the Git help pages use Git-specific jargon, which really interferes with non-experts understanding what a command does.
The book adopts a style that should be accessible to new users. It’s informal , with plenty of first- and second-person references. This is not a “dummies” book; I’m not going to talk down to you, and I’m not going to suggest that you shouldn’t learn complex concepts about Git. But I’m going to try to talk about how I use Git and how I see it being used effectively.

Answering common questions about MIT and Harvard’s new partnership in online education.
Jan Bergmans's insight:
What technology will edX use? An open-source online learning platform that will feature teaching designed specifically for the Web. Features will include: self-paced learning, online discussion groups, wiki-based collaborative learning, assessment of learning as a student progresses through a course, and online laboratories. The platform will also serve as a laboratory from which data will be gathered to better understand how students learn. Because it is open-source, the platform will be improved continuously.
Is there anything innovative about the online technology? Yes. It will move beyond the standard model of online education that relies on watching video content and will offer an interactive experience for students. And the technology will be open-source; other universities will be able to leverage the innovative technology to create their own online offerings.
Why are MIT and Harvard doing this? To improve education on campus and around the world:
On campus, edX research will enhance our understanding of how students learn and how technologies can best be used as part of our larger efforts to improve teaching and learning.Beyond our campuses, edX will expand access to education, allow for certificates of mastery to be earned by able learners, and make the open-source platform available to other institutions.
Ripped off on a 256MB RAM stick? Today's your lucky day
Jan Bergmans's insight:
A group of US Attorneys General have agreed to a $310m settlement package with memory chip makers, which is to be distributed among the public, following allegations of price gouging by vendors between the years 1998 and 2002. DRAM makers named in the paperwork include Samsung, Micron, Hynix, Infineon, NEC, and Toshiba. They all deny any wrongdoing, and settled out of court in California.
Under the terms of the deal, US residents and companies can file claims to receive a slice of the cash pie based on DRAM they purchased during the four-year period. The payouts start at $10, and the attorneys say the, er, victims could receive "much more" for their troubles.
The settlements come from a lawsuit first filed in 2007 that accused DRAM manufacturers of price-fixing. The allegations claim that over the four-year period spanning the turn of the century, the vendors sought to gouge customers by colluding to artificially drive up the price of memory.
Various other settlements have been reached previously, including a $300m deal in 2005 between Samsung and the US Department of Justice. The $310m being distributed now is the result of motions brought forward by 33 state Attorneys Generals on behalf of the public.
In order to claim a share of the loot, customers will need to file a claim by 1 August, 2014 through the DRAMclaims website or print out and send in a written claim form.
If, for whatever reason, users want to opt out of the agreement (most likely in order to file a separate suit) the deadline to file is 5 May. ®
We all know Linux is popular but here are a few places where it is not expected to be. EFYTimes takes a look.
Jan Bergmans's insight:
Government Users of Linux
1.U.S. Navy Submarine Fleet – As per FreeSoftwareMagazine.com "the US Navy nuclear submarine fleet is using GNU/Linux" too.
2.The City of Munich, Germany - The city of Munich, Germany has "chosen to migrate its 14,000 desktops to a free Linux distribution, rather than a commercial version of the open source operating system" as per 2005 ZDNet report.
3.Spain – As per LWN.net, Spain remains the strongest supporter and user of Linux from a national government perspective. Linux is widespread all over Spain since 2002, when the government of Extremadura made its own customized Linux distribution (called LinEx) based on Debian, utilising GNOME as its "default desktop environment."
4. Federal Aviation Administration – A couple of government users of Linux seem to be happier with their choice to switch than the United States Federal Aviation Administration. As per Wikipedia, the FAA made an announcement in 2006 that it "had completed a migration to Red Hat Enterprise Linux in one third of the scheduled time and saved 15 million dollars" while doing so.
5.French Parliament - French Parliament chose in November 2006 to get rid of Windows for Ubuntu Linux, as per ZDNet. This move was a component of a comprehensive shake-up in the software run on Parliament computers that resulted in "1,154 French parliamentary workstations running on Linux, with OpenOffice.org productivity software, the Firefox Web browser and an open-source e-mail client."
6. State-Owned Industrial and Commercial Bank of China – As per 2005 InformationWeek report, the state-owned Industrial and Commercial Bank of China "decided to roll out Linux in all of its 20,000 retail branches." Being the largest bank in entire China, the institution made a commitment to purchasing "an unrestricted user license" as part of a wide integration of Linux "throughout its entire banking operations network" that culminated in 2008.
7. Pakistani Schools & Colleges - In 2002, the Pakistani government brought about a Technology Resource Mobilisation Unit for promoting the spread of open-source software (as well as Linux) all over the country. The unit (that comprises of academics, businesspeople and government officials) has hugely been successful in educating computer users all over Pakistan about what free software could offer.
Educational Users of Linux
8. Russian Schools - In 2007, Russia made an announcement that all its schools would start running Linux software. As per a BBC report on the matter "schools formerly tended to run illegal copies of Microsoft operating systems", but as Russia joined the WTO, it was no longer an accepted practice.
9.German Universities - ComputerWeekly.com stated in August 2007 that "around 560,000 German students plus thousands of staff at 33 German universities will now be supported by Linux systems from Novell."
10. The Philippines - The taking over of Linux is stated to be "forging an education revolution" in the Philippines, as per ComputerWorld. As explained by them, "after a successful deployment of 13,000 Fedora Linux systems from a government grant, plans are underway to roll out another 10,000 based on Ubuntu" in that country.
11.Georgia – The former Soviet state Georgia started running all its school computers and LTSP thin clients on Linux, primarily using Kubuntu, Ubuntu and took away Fedora-based distributions in 2004, as per Wikipedia.
12. The Indian State of Tamil Nadu - LinuxWatch.com reported the story of how "after being put off by Microsoft's bundling tactics for academic users", the Indian state of Tamil Nadu made a decision that instead of distributing 100,000 Linux laptops to students there.
13. Switzerland Schools - Wikipedia stated that Switzerland changed 9,000 of its computers to using Linux and OpenOffice.org's suite of office productivity tools in its Geneva district in September 2008.
14. Bolzano, Italy - Balzano in Italy having a student population of 16,000) switched to making use of a customized distribution of Linux across all its schools in 2005.
15.Kerela, India - Rediff.com stated in September 2006 that beginning now, in Kerela, India, "nearly 1.5 million students in the 2,650 government and government-aided high schools in the state will no longer use the Windows platform for computer education. Instead, they have switched over to the free GNU/Linux software."
Business Users of Linux
16.Novell – For a prolonged period, software and services company Novell made an announcement in 2006 that it was going through a company-wide migration from Windows to Linux on employee desktop computers. Since April 2006, nearly half of Novell's 5,000+ workforce had migrated to Linux, with that figure to rise to 80% by November.
17.Google - The huge and ever-growing group of servers powering Google's search and other apps running on Linux. Of course, typically Google was not satisfied of simply running an out of the box version on its own hardware.
18.IBM – Adding on to doing development work on Linux, IBM also uses it internally on desktops and servers. IBM started a TV ad campaign in 2006 known as "IBM Supports Linux 100%."
19.Panasonic – The Electronics giant Panasonic uses Linux in powering a few of its operations. Similar to many other firms on this list, Panasonic made use of Linux only after Windows NT proved woefully insufficient for what the company required - voicemail systems.
20.Virgin America – This is a low-cost U.S. airline that is run by Richard Branson, that used Linux to power its in-flight entertainment as per TechCrunch. The entertainment system (known as RED) is powered by Red Hat and Fedora specifically, and was opted for as it’s "very stable and agile."

Tim Berners-Lee: We need to re-decentralize the WebThe greatest danger is the emergence of a balkanized Internet.

BroadbandInternet regulation100Chris Woods
Twenty-five years after the Web's inception, its creator has urged the public to reengage with its original design: a decentralized Internet that remains open to all.
Speaking with Wired editor David Rowan at an event launching the magazine's March issue, Tim Berners-Lee said that although part of this is about keeping an eye on for-profit Internet monopolies such as search engines and social networks, the greatest danger is the emergence of a balkanized Web.
"I want a Web that's open, works internationally, works as well as possible, and is not nation-based," Berners-Lee told the audience, which included Martha Lane Fox, Jake Davis (aka Topiary) and Lily Cole. He suggested one example to the contrary: "What I don't want is a Web where the Brazilian government has every social network's data stored on servers on Brazilian soil. That would make it so difficult to set one up."
It's the role of governments, startups, and journalists to keep that conversation at the fore, he added, because the pace of change is not slowing—it's going faster than ever before. For his part, Berners-Lee drives the issue through his work at the Open Data Institute, World Wide Web Consortium, and World Wide Web Foundation, but also as an MIT professor whose students are "building new architectures for the Web where it's decentralized." On the issue of monopolies, Berners-Lee did say that it's concerning to be "reliant on big companies and one big server," something that stalls innovation, but that competition has historically resolved these issues and will continue to do so.

Jan Bergmans's insight:
against my person several times and unfortunately on the Ubuntu Planet there is still a blog post which attacks me personally without any sign that this will change. As I had been attacked by the Ubuntu community quite a lot over the last half year and I had to ask Jonathan to tell Jono that I’m not the scape goat for Ubuntu, I think it is important that I stand up against this and point out the abusive behavior we get from the Ubuntu community.
First of all I want to verbatim quote the Ubuntu Code of Conduct:
Disagreement is no excuse for poor manners. We work together to resolve conflict, assume good intentions and do our best to act in an empathic fashion. We don’t allow frustration to turn into a personal attack. A community where people feel uncomfortable or threatened is not a productive one
That is broadly what has been said about quantum computers up to now, but it's probably best to pause here and be clear about what is, at this stage, most likely to come.
First things first, though: just what do they do? Many media outlets have dived into the academic literature sporadically to shed some light on the effort.
BBC News has reported that quantum computers "exploit the counterintuitive fact that photons or trapped atoms can exist in multiple states or 'superpositions' at the same time", and "quantum computing's one trick is to perform calculations on all superposition states at once" - plus, other quantum weirdness means the whole business "can then be done 'in the cloud' completely securely".
This week has seen two more advances in the field. In one, a team reporting in Nature describes the first fully quantum network, in which "qubits" - quantum bits, the information currency of quantum computers - were faithfully shuttled between two laboratories.
In another, a team writing in Science says they have "entangled" two qubits - representing the simplest core of a quantum computer - within a semiconductor, materials that standard computer makers are already familiar with manufacturing.
(It has been truly busy recently; the largest ensemble of working qubits was reported on Arxiv in January, and the biggest quantum computer number-crunching feat was published in Physical Review Letters in late March.)
Bet it works
It is all a bit bewildering, so to sum up the state of the field: very small-scale, laboratory-bound quantum computers that can solve simple problems exist; most researchers say the idea of massively scaled-up versions looks perfectly plausible on paper; but making them is an engineering challenge that practically defies quantifying.
Scott Aaronson, an expert in the theory of computation at the Massachusetts Institute of Technology, is one believer in the scaled-up quantum computer. He recently offered a $100,000 prize for a convincing proof that such a device could not be made.
Continue reading the main storyEssence of the quantum advantage
Scott Aaronson, MIT
You frequently hear that quantum computers "try all the possibilities in parallel" - that's a very drastic oversimplification.
We talk about a 30% chance of rain tomorrow - we'd never say there's a negative 30% chance. But quantum mechanics is based on "amplitudes", which can also be negative. If you want to find the probability that something will happen, you have to add up all the amplitudes.
With a quantum computation you're trying to choreograph things such that for a given wrong answer there are all these different paths that could lead to it, some with positive amplitude and others with negative amplitude - they cancel each other out.
For a given right answer, the paths leading to that should all be positive or all negative, and amplitudes reinforce. When you measure it, the right answer should be measured with high probability.
But he has no illusions that it is just around the corner.
"I get kind of annoyed by all the (popular media) articles reporting every little experimental advance," he told BBC News.
"The journalists have to sell everything, so they present each thing like we're really on the verge of a quantum computer - but it's just another step in what is a large and very difficult research effort.
"It was more than 100 years between Charles Babbage and the invention of the transistor, so I feel like if we can beat that, then we're doing well - but that's a hundred years for people to say 'works great on paper, but where is it?'"
More than that, though, even the most optimistic researchers believe that quantum computers will not be a wholesale replacement for computers as we now know them.
The only applications that everyone can agree that quantum computers will do markedly better are code-breaking and creating useful simulations of systems in nature in which quantum mechanics plays a part.
Martin Plenio, director of the Institute for Theoretical Physics at the University of Ulm, Germany, said that "it might never happen that it will be a device that sits here under my desk".
"A quantum computer can do all the things that a classical computer can do, and some of those things it can do much better, faster, like factoring large numbers," he told BBC News.
"But for many questions it's not going to be superior at all. There is simply no point to use a quantum computer to do your word processing."
Others are more sanguine about the utility of what will come out of the current research efforts.
Alan Woodward, a professor of computing at the University of Surrey, cites a couple of recent advances that, to his mind, signify a significant push toward a computer that might sit under his or Prof Plenio's desk.
Quantum experiments are still complex and bulky lab-based beasts
Most quantum computers to date have been designed to tackle a single problem, unlike the general-purpose computers we use now. But Prof Woodward says that a report in Nature Photonics in December represents the first "programmable" quantum computer.
And, he said it is significant that an industry giant like IBM is getting into the game; at a meeting of the American Physical Society in March, IBM researchers reported significant advances in just how long they could preserve the quantum information in their qubits.
"Are you going to have a purely quantum computer in five years? No - what you'll have is elements of these things coming out, you always do with technology," he told BBC News.
"In the same way you have a graphics processor card along with a main processor board in a modern computer, you'll see things added on; people will find a means of using quantum computing and the quantum techniques, and that's how I think it'll move forward.
"And those I can definitely see in the five-year period."
Prof Woodward is in the minority in thinking that the consumer market will benefit widely from quantum computers; the problem of course is making predictions about a technology that has, since its inception, always seemed possible but even now is not incontrovertibly achievable.
Dr Aaronson concedes that perhaps the long term may bear out a greater desire and use for it.
"It's hard for me to envision why you'd want a quantum computer for checking your email or for playing Angry Birds. But to be fair, people in the 1950s said 'I don't see why anyone would want a computer in their home', so maybe this is just limited imagination.
"Maybe quantum video games will be all the rage 100 years from now."
I’ve been waiting for a web-based tablet and it looks like it’s coming soon. But it’s not the Chrome tablet I was expecting. Instead, meet the first slate in the Firefox OS tablet program.
Jan Bergmans's insight:
While the device may seem relatively underpowered, I see it as a solid reference design for the Mozilla team to demonstrate and mature its Firefox OS platform. And I’d also expect a web-based platform wouldn’t need super-powerful (read: energy hungry) hardware to perform admirably. The Google Chromebooks with ARM-based chips are a good example that adequate performance can be had without a desktop-class chip.
My hope was actually for Google to have created a 2-in-1 Chrome tablet by now: A laptop dock with a removable tablet screen for example. That hasn’t happened yet. While I continue waiting for this, I’ll be keen to get my hands on one of the Firefox OS tablets to see what the experience is like.

We're looking at an Android-based phone with a "top performing" processor and a cellular module that will be unlocked, free of geographical restrictions and compatible with any GSM network. In place of carrier bloatware, we're promised a skin called "PrivatOS" that will allow you to make and receive secure phone calls and text messages, store files securely and browse the web privately through an anonymous VPN -- services that are largely already available from Silent Circle, which happens to be a key partner on the Blackphone project. That's pretty much all we know for now, but pre-orders will begin sometime during the last week of February, and by then we hope to have hands-on impressions and a better understanding of how Blackphone will be different to BlackBerry encryption, Samsung's Knox service and other more established rivals.

De VPN-software is inmiddels op meer dan 80.000 servers geïnstalleerd en heeft dagelijks meer dan 110.000 gebruikers. Door het opensource maken van de broncode hoopt Nobori en de andere ontwikkelaars van SoftEther VPN dat programmeurs en ontwikkelaars aan de hand van de broncode kunnen leren hoe ze een VPN-protocol-engine kunnen ontwikkelen.
"We denken dat gebruiksvriendelijke softwaregebaseerde VPN-tools noodzakelijk zijn om een vrij internet te bereiken. Vrij internet betekent dat overheden de communicatie van mensen niet kunnen censureren of aftappen, en mensen communicatietechnologie kunnen gebruiken zonder bang te zijn voor onderdrukking door hun overheid."
Door de broncode van SoftEther VPN te gebruiken kunnen nu ook andere ontwikkelaars hun eigen VPN-gebaseerde applicatie ontwikkelen, laat Nobori weten. "We hopen dat het uitbrengen van de SoftEther VPN broncode dit soort ontwikkelaars zal helpen, en in de toekomst ook helpt bij het bereiken van een vrij internet."
