Announcement: Diaspora* Will Now Be A Community Project

Dear Community,

We have been overwhelmed with your support the past week after our announcement of Makr.io and the opening up of signups on joindiaspora.com. This week, we are excited to share with you some important Diaspora announcements.

When we started Diaspora two years ago, the project kicked off with amazing reception and support from people that believed in our ultimate goal: giving users ownership over their data. It’s a powerful idea, one that captured the imaginations of millions of people across the world. This vision has expanded and evolved over the past two years that we have been working on it as the project has grown.

Diaspora* began when we were still at NYU – just four guys trying to scratch our own itch. We had an idea about how social networks could work in a new and exciting way. We intended to be done over the course of a summer, and with an expected budget of $10,000 from our Kickstarter campaign. The reception of this idea was so good that we managed to reach 20 times the expected amount in donations, and the project expanded to cover far more than just a summer. It’s been over two years now, and we are proud of what Diaspora has become.

Money can't buy open-source love... only code can • The Register

Money can't buy open-source love... only code can • The Register | Linux A Future | Scoop.it

Linus Torvalds started with nothing
By Matt Asay • Get more from this author

Posted in Developer, 27th July 2012 13:02 GMT
Open ... and Shut Money can't buy you happiness, but Meteor, a web-apps startup focused on enterprise app development, seems to think it can buy it an open-source community.

Instead of the standard startup funding announcement, proclaiming that the company will use its funding for product development, marketing and so on, Meteor says it "will use the money to build the open source community around its offerings."

Is that so? Who knew all you needed for an open-source community was $11.2m in venture funding?

This may be a bit harsh. After all, Meteor's board is filled with people who understand that money can't buy a community. David Skok invested in and helped to build JBoss's commercial business. Rod Johnson built up a massive, two-million strong Spring community. Peter Levine also has an open-source pedigree, having run XenSource until its acquisition by Citrix.

But guess what? In exactly zero of those cases did venture money buy a community. The opposite, in fact, happened.

JBoss had tens of thousands of monthly downloads and a broad community well before Skok's Matrix Partners invested in it. It was the community, in fact, that attracted him to JBoss. Ditto for Johnson's SpringSource, which funded itself for years with consulting work while it sowed a dedicated Spring community.

Many open-source startups raised money in the heady days of 2004 through 2009 on the promise of leveraging existing communities or building new communities around their open-source projects. In the latter case, virtually all failed to actually create community, because open-source community really isn't a matter of money.

Linux Kernel 3.5 Has Been Officially Released

Linux Kernel 3.5 Has Been Officially Released | Linux A Future | Scoop.it
After yet another seven Release Candidate versions, Linus Torvalds proudly announced yesterday, July 21st, the immediate availability for download of Linux kernel 3.5.

Linux kernel 3.5 brings various interesting features (check out the highlights below and the quote from Linus Torvalds’ announcement) among which we can mention support for metadata checksums in the EXT4 filesystem, support for restoring and checkpointing TCP connections, support for TCP Early Retransmit (RFC 5827), a new network queue management algorithm designed to fight bufferbloat, Btrfs I/O failure statistics, and much more.

“There's a number of MIPS commits (for some reason MIPS has had a horrible track record with the -rc time schedule, I suspect I should just stop pulling late in the game), but most of the rest is pretty small.”

“A couple of dm/md fixes, some gma500 work, make kgdb 'dmesg' command work again, some networking fixes, some xfs and cifs noise, yadda yadda. About 50% of the patch is actually the SPEAr clock name renaming that is just some search-and-replace,” said Linus Torvalds in the official announcement.

Highlights of Linux Kernel 3.5:

· EXT4 metadata checksums;
· Uprobes: userspace probes;
· Seccomp-based system call filtering;
· Bufferbloat fighting: CoDel queue management;
· TCP connection repair;
· TCP Early Retransmit;
· Android-style opportunistic suspend;
· Btrfs: I/O failure statistics, latency improvements;
· SCSI over FireWire and USB.

Linux kernel 3.5 also comes with many improvements in various areas, such as memory management fixes, networking, virtualization, security, perf/tracing, block, improvements to Btrfs, Tmpfs, XFS, CIFS, JFFS2, exofs, Cifs filesystems, as well as various core changes.

4 Fine Linux ARM Distros | Linux.com

4 Fine Linux ARM Distros | Linux.com | Linux A Future | Scoop.it
Carla Schroder writes: The ARM platform is exploding like a mad wet cat out of the bath. Here are four good distros cram-full of ARM fun.

 

Linux has had ARM support since forever, but it's been bumpy. There are hundreds of vendors of ARM devices (see Tiny Pluggable Linux ARM Computers Are Red-Hot for a sampling), all shoving their own personal hacked code out the door as fast as possible. This made Linux support complicated and unwieldy, to the point that Linus Torvalds threatened to stop accepting ARM changes in the mainline Linux kernel.

So, in classic Linux fashion, vendors and developers banded together and coordinated and consolidated their efforts, formed the Linaro non-profit engineering organization, and performed a sizable cleanup of redundant and bad code. Jonathan Corbet, editor of Linux Weekly News, predicts that "ARM will take its place as one of the primary Linux architectures" in 2012. This seems a safe prediction as ARM-based mobile devices are going to continue to sell like ice water in hell.

Android is also expected to harmonize, over time, with the mainline Linux kernel. So this confluence of ARM events means that we who like to play with stuff will have a little easier time of it. Me, I dream of embedded and mobile devices being as friendly to experimentation as the x86 platform. Don't laugh, it could happen. So which Linux is best for ARM? Why, lots of them.

There are a lot of different ARM processors, so this guide should help you sort them out. Wikipedia has an invaluable table that lists all the ARM microprocessor cores, so when you see terms like ARMv5TE or ARM9TDMI or Cortex-something, consult this table to know what the heck these are.

FAUMachine: First Impressions

FAUMachine: First Impressions | Linux A Future | Scoop.it
If you'd like to try a new twist on virtualization, FAUmachine might be the next cool thing.

 

For those of you who don’t already know about FAUmachine (FAU), it’s a virtual machine that allows you to install full operating systems and run them as if they were independent computers. FAUmachine is similar to VirtualBox, QEMU, and other full virtualization technologies. It is a project sponsored by the Friedrich Alexander University Computer Science Department in Germany (Erlangen-Nuremberg*). FAU is a computer simulator that is an independent virtual machine project. The CPU is based on the virtual CPU in QEMU.

FAU distinguishes itself from other virtualization technologies in the following ways:

FAU runs as a normal user process. Root privileges and kernel modules not required.Fault injection capability for experimentation.VHDL interpreter and several example scripts for the VHDL interpreter.

From the FAUmachine web site:

FAUmachine simulates a large variety of different hardware components, including several x86 and x86_64 CPUs,

IDE and SCSI controllers,NE2000- and Intel eepro100 network interface adapters,a Sound Blaster 16 sound card,a generic VGA and a Cirrus GD5446 graphics adapter,a 24 and a 48 pin direct-I/O PCI-card,

but also peripherals such as

networking hubs and routers,serial terminals,modems,USB-to-Serial adapters,and even a three-story elevator.***

FAU also simulates the whole PC environment, like the power switch, the monitor, the power supply, and more. You can also configure memor

JAP -- ANONYMITY & PRIVACY

JAP -- ANONYMITY & PRIVACY | Linux A Future | Scoop.it

Project: AN.ON - Anonymity.Online

Protection of Privacy on the Internet

JAP (called JonDo in the scope of the commercial JonDonym anonymous proxy servers - AN.ON remains free of charge) makes it possible to surf the internet anonymously and unobservably.

Without Anonymization, every computer in the internet communicates using a traceable Address. That means:

the website visited,the internet service provider (ISP),and any eavesdropper on the internet connection

can determine which websites the user of a specific computer visits. Even the information which the user calls up can be intercepted and seen if encryptionis not used. JAP uses a single static address which is shared by many JAP users. That way neither the visited website, nor an eavesdropper can determine which user visited which website.How it works

Instead of connecting directly to a webserver, users take a detour, connecting with encryption through several intermediaries, so-called Mixes. JAP uses a predetermined sequence for the mixes. Such a sequence of linked mixes is called a Mix Cascade. Users can choose between different mix cascades.

Since many users use these intermediaries at the same time, the internet connection of any one single user is hidden among the connections of all the other users. No one, not anyone from outside, not any of the other users, not even the provider of the intermediary service can determine which connection belongs to which user. A relationship between a connection and its user could only be determined if all intermediaries worked together to sabotage the anonymization. more...

The intermediaries (mix providers) are generally provided by independent institutions which officially declare, that they do not keep connection log files or exchange such data with other mix providers. JAP shows the identity and number of organisations in each Mix cascade in detail, and verifies this information by cryptographic means. The users are thus able to selectively choose trustable mix cascades.

My Journal on debian

By jayberg 8/30/2012

Excerpts:

Debian can be used on a variety of hardware, from laptops and desktops to NAS devices, phones, and servers.(http://en.wikipedia.org/wiki/Debian) Debian developers expect that a two-year release cycle will give more time for disruptive changes, reducing inconveniences caused for users.(http://en.wikipedia.org/wiki/Debian) Debian has a security audit team that reviews the archive looking for new or unfixed security bugs.(http://en.wikipedia.org/wiki/Debian) The end goal is to allow all projects which deal with the process of generating a debian package to start testing their code.(http://planet.debian.net/) For packages to become candidates for the next "stable" release of the Debian distribution, they first need to be included in the "testing" suite.(http://en.wikipedia.org/wiki/Debian) These commands will configure the system package manager with the NeuroDebian repository key and package source information.(http://neuro.debian.net/) Instructions on rebuilding the source packages are also applicable to other Debian derivatives and custom distributions not covered here.(http://wiki.scribus.net/canvas/Debian) You can then use almost all of the packages available for Debian, with just one call to apt-get install.(http://wiki.debian.org/DebianOnFreeRunner) Jump to: navigation, search Description: Candidates should be able to perform package management using the Debian package manager.(http://en.wikibooks.org/wiki/LPI_Linux_Certification/Use_Debian_Package_Management) A hard disk installation can be achieved using the Debian Installer included in the live image.(http://en.wikipedia.org/wiki/Debian) If you want to learn something about your new Debian system, you can read the installation script and do the steps by hand.(http://wiki.debian.org/DebianOnFreeRunner) The basis of Debian provides a great infrastructure for bringing more mobile-oriented software by packaging it as part of our team.(http://wiki.debian.org/DebianOnFreeRunner) Submit a problem report for Audacity for Debian Please describe the problem you have with this software.(http://download.cnet.com/Audacity-for-Debian/3000-2170_4-75207040.html) Submit a problem report for Opera for Debian Please describe the problem you have with this software.(http://download.cnet.com/Opera-for-Debian/3000-2356_4-75285825.html) We want to express our gratitude to all maintainers that help to make Debian the ultimate software platform for neuroscience.(http://neuro.debian.net/) With Debian, you don't have to worry about forced upgrades due to vendors dropping support for older versions.(http://www.aboutdebian.com/) French support I have added some guidelines in french to install Debian on the Slug, with an associated support forum.(http://www.nslu2-linux.org/wiki/Debian/HomePage) Both the Debian distribution and their website have won various awards from different organizations.(http://en.wikipedia.org/wiki/Debian) Today, in this project, Debian is developed by more than 1,000 computer specialists all over the world.(http://simple.wikipedia.org/wiki/Debian) Depending on the architecture, it is possible to install Debian with as little as 20 MB RAM for s390 or 48 MB RAM for i386 and AMD64.(http://en.wikipedia.org/wiki/Debian) This allows the user to try out Debian before installing it or use it as a boot-disk.(http://en.wikipedia.org/wiki/Debian) The Debian project has a steady influx of applicants wishing to become developers.(http://en.wikipedia.org/wiki/Debian) Do it by pushing buttons, no just typing reboot, otherwise you will just reboot into the previous non-debian world.(http://wiki.debian.org/DebianOnFreeRunner) If you're the type who likes to base your operations on the bleeding edge, Debian isn't for you.(http://www.aboutdebian.com/) As an alternative, we have chosen to use Amazon book links and sell Debian discs to try and raise the funds necessary to keep this site operating.(http://www.aboutdebian.com/) The Debian Project, being free software, handles security policy through public disclosure rather than through security through obscurity.(http://en.wikipedia.org/wiki/Debian) From Audacity Developer Team: Audacity for Debian is a cross-platform multitrack audio editor.(http://download.cnet.com/Audacity-for-Debian/3000-2170_4-75207040.html) A role in Debian with a similar importance to the Project Leader's is that of a Release Manager.(http://en.wikipedia.org/wiki/Debian) The code names of Debian releases are names of characters from the film Toy Story.(http://en.wikipedia.org/wiki/Debian) The Debian Project discourages the use of these repositories as they are not part of the project.(http://en.wikipedia.org/wiki/Debian) This setup requires a manual bootstrap procedure and is no longer the recommended solution to run Debian in the slug.(http://www.nslu2-linux.org/wiki/Debian/HomePage) Now you do not need to mess with modifying U-Boot's default setup, and can still boot to Debian using NOR boot.(http://wiki.debian.org/DebianOnFreeRunner) In addition, Debian was the Linux of choice for a Space Shuttle mission back in 1997.(http://www.aboutdebian.com/) With Debian, you don't have different "server" and "workstation" or "personal" editions.(http://www.aboutdebian.com/) While most OSs require newer, faster, bigger hardware, Debian allows you to utilize those old Pentium systems instead of throwing them into a landfill.(http://www.aboutdebian.com/) Time-based freezes are intended to allow the Debian Project to blend the predictability of time based releases with its policy of feature based releases.(http://en.wikipedia.org/wiki/Debian) You cannot reliably infer whether a given package version is sufficient as a dependency or not, when comparing binary packages between Red Hat and Debian.(http://planet.debian.net/) Debian is the world's leading non-commercial totally free Linux distribution.(http://www.aboutdebian.com/) The information is used to maintain your accounts on various Debian machines, and also to allow other developers and general users to find out more about you.(http://planet-fr.debian.net/) Many of the fields are only visible to other registered Debian developers.(http://planet-fr.debian.net/) Debian's focus on providing a stable, reliable operating system across all hardware platforms means it will never be "first to market" with new bells and whistles.(http://www.aboutdebian.com/) To install Debian on your MicroSD card, you need to have any Linux system running already in flash.(http://wiki.debian.org/DebianOnFreeRunner) We are using Mika Prokop's jenkins-debian-glue scripts for driving the package build from Jenkins.(http://planet.debian.net/) In case you have discovered a new bug, then submit it, but please: o One possible cause is a problem with the armel packages in Debian.(http://wiki.debian.org/DebianOnFreeRunner) NeuroDebian provides a turnkey software platform for neuroscience that is created by integrating research tools with the Debian operating system.(http://neuro.debian.net/) Ubuntu has releases every 6 months which are forks of Debian's unstable distribution with bug fixes and other modifications.(http://en.wikipedia.org/wiki/Debian) This solution uses the SlugOS kernel in little-endian mode, in a way that is compatible with the Debian arm distribution.(http://www.nslu2-linux.org/wiki/Debian/HomePage) Add this line If you are using 64-bit Debian, install the 32-bit fglrx libraries for use with 32-bit programs.(http://wiki.cchtml.com/index.php/Debian) If you are using 64-bit Debian, install the 32-bit fglrx libraries for use with 32-bit programs.(http://wiki.cchtml.com/index.php/Debian) The first thing to check is that you have enough memory: on a system with 32Mb physical RAM Debian might only install another 90Mb swapspace.(http://www.nslu2-linux.org/wiki/Debian/HomePage) Perens was also responsible for many policy and design elements of Debian that persist to this day.(http://en.wikipedia.org/wiki/Debian) In order to get it running, I made several patches: Me and my mentor contacted the Debian wanna-build team to connect our new service with Debian.(http://planet.debian.net/)

Open Source Privacy Policy for Mobile Apps

Yesterday we launched a special project: an open source, standard privacy policy for mobile apps. We want to help developers comply with the law while maintaining transparent, trust-inspiring user practices. We created three versions (for generic, ad-supported and location-basedapps) of a model privacy policy that provides a sensible, fair starting point. Open sourcing the language will empower users to easily view and compare different policies. It also provides the foundation to allow public standards to emerge.Please, share this project and contribute by branching these policies into more specific or improved versions. We want these privacy policies to evolve with the collective knowledge and constructive criticism of our community! Read more.

Retail CIOs: How to Love Your Linux Operating System

Posted by Simon Mitchell on Wed, Jun 20, 2012 @ 04:00 AM

Gain skills to support your retail Open Source roll-out

Moving to ‘free’ Open Source software (OSS) from licensed proprietary software often seems like it’s a no contest. Yet OSS doesn’t mean that organisations like your own can just install the latest Open Source software and leave it to its own devices – particularly if you wish to avoid mounting hidden expenses. Like the romantic partner in your life, OSS needs some tender, loving care to make sure that it delivers the results your retail organisation requires.

“Done correctly, maintaining and managing Open Source environments can be easier than proprietary ones due to the number of management tools that are available and the scriptability of UNIX in general”, says Mark Reynolds, Director of Technology at Linux consulting expert LinuxIT. He adds the following points for consideration:

Open Source installations for retail or for any other sector should be automated to create a high level of predictability;Software components should be packaged using an appropriate distribution format for Linux to allow for easier upgrades and downgrades as well as simpler integration with other software companies;Larger scale deployments will require centralised patch deployment and configuration management tools, such as Red Hat satellite server or Puppet, to significantly rationalise overheads.

As a retailer, our teams are sure you can’t afford any disruption, and so to minimise it you might want to consider working with a company like Linux consulting expert LinuxIT – particularly if you need access to strong systems administration skills, which are founded on the understanding of current industry best practices like ITIL, Visible Ops and so on. Furthermore, by working with LinuxIT you can enhance your existing IT skills to ensure that the project is a success.

“There is a steep learning curve with moving from Microsoft Windows environments to Linux, and companies should engage with third parties to get the initial infrastructure right from the start to prevent Linux and Open Source software from becoming an experiment”, says Reynolds.

Playing war games to prepare for a cyberattack - McKinsey Quarterly - Business Technology - Organization

Playing war games to prepare for a cyberattack - McKinsey Quarterly - Business Technology - Organization | Linux A Future | Scoop.it
A poor response can be far more damaging than the attack itself. A McKinsey Quarterly Business Technology article.

 

Can it happen to us?” All over the world, technology executives have been fielding this question from boards of directors and CEOs in the wake of highly publicized cyberattacks on large, well-respected companies and public institutions.
“Yes” is the only honest answer at a time when ever more value is migrating online, when business strategies require more open and interconnected technology environments, when attackers have always-expanding capabilities, and when attacks take advantage of limited security awareness among employees and customers. In fact, it may already have happened to you—but you may not know it.
Although political “hacktivists,” such as Anonymous and LulzSec, certainly delight in announcing their exploits to the world and causing embarrassment to their targets, other sophisticated attackers seek to cover their tracks. Organized-crime rings engaging in cyberfraud have no interest in letting their targets know they have been infiltrated.
We believe that boards and senior business leaders should be asking the technology team a different question—namely, “Are we ready to respond to a cyberattack?”
An ill-thought-out response can be far more damaging than the attack itself. Whether customers cancel their accounts in the wake of a successful cyberattack depends as much on the quality of a company’s communications as on the gravity of the breach. How much value is destroyed by the loss of sensitive business plans depends on the ability to adjust tactics quickly.

Five Common Misconceptions About Linux

Five Common Misconceptions About Linux | Linux A Future | Scoop.it

The recent hubbub over Linus Torvalds’ comments towards Nvidia as well as Nvidia’s response to those comments have once again brought up intense debates between Linux users and the rest of the computing pack. Reading the comments on Engadget or The Verge for these news articles, I realized that the general public has some misconceptions about Linux and its ecosystem. I use Linux distributions every single day both on my phone and on the desktop. When I read such comments, I find it kind of funny, but also kind of sad that the Linux that I use so routinely and productively is getting this sort of rap. So here, now, are five misconceptions I think I see most commonly on the Internet regarding Linux and its ecosystem.

Misconception #1: Linux is an operating system

I just wanted to get this one out of the way really quick. Linux is not an operating system. Instead, it is a kernel. It sits in between the hardware and the actual operating system (Linux distributions, as they are called) to enable all the userspace software to run smoothly and correctly.

Misconception #2: Linux has terrible driver support

The whole news about Torvalds’ Nvidia comments I mentioned earlier stemmed a bunch of comments on driver support in Linux from a ton of people. Neglecting the fact that most of the commenters didn’t actually see the talk in which Linus made his remarks and thusly assumed he was just saying Nvidia’s driver support on Linux was awful, most of the comments were pretty misinformed in general.

In regards to Nvidia, its proprietary drivers are actually pretty superb as far as performance goes. This is one of the things Engadget and The Verge participators were griping about, and rebutting that AMD’s graphics drivers are terrible. The truth is, AMD’s Catalyst drivers (its proprietary set) are also excellent and wonderful and masterful and all that. Its open source driver, dubbed “radeon” in the Linux kernel, works pretty well too, albeit with some 3D performance issues.

Apart from graphics, I’ve never had any real problem with other drivers. LockerGnome writer Ryan Pierson talked with me earlier and make the comment that he had struggles with a wireless card in one of his old notebook computers a few years ago. To be honest, those are edge cases, especially in this day and age. Wireless cards are fairly well supported (by the manufacturers, even) on Linux, especially if you have one of the mainstream brands (Broadcom, Intel, etc.), which you most likely are to have. As such, I can only assume that any driver issues that one person might encounter is either: a] user error, or b] a rare edge case, which means you shouldn’t go spouting off on a technology site to complain that Linux has terrible driver support if you can’t get your collection of silicon to work correctly.

I should note, however, that notebooks with Nvidia Optimus are a problem area — one that Linus was specifically targeting when he made his remarks. The issue with Optimus is that Nvidia has refused to support it on Linux in its proprietary driver, and it offers no support to the open source alternative, Nouveau, whose team is forced to reverse-engineer Nvidia cards in order to write the drivers. This lack of support on Linux can cause a variety of problems, from both GPUs (the integrated GPU as well as the Nvidia GPU) to run at the same time and waste battery life, to the worst case scenario of your laptop booting to a black screen of death, so to speak. This isn’t Linux’s fault, though, it’s Nvidia’s. The Linux community has been asking Nvidia to merely release the specifications behind its hardware so that the open source community at least has a good shot at writing working drivers. AMD has done this with its Radeon graphics line, even going so far as to committing employees to assist with the development of the open source driver. One last note if you’re reading this and you are affected by the Optimus issue on Linux: Try giving the Bumblebee project a look.

Misconception #3: There isn’t any decent software available for Linux

I have had this discussion with the other LockerGnome writers plenty of times, and we usually come to agree that the software available on Linux is definitely usable save for a few specific workflows. If you need a photo editor, use the GIMP or another alternative. If you want an office suite, there’s LibreOffice or you could even use Google Docs online. Linux has games, browsers, video editors, vector image editors, screencasters, instant messaging and IRC clients, development tools (oh boy, the development tools!), and so much more to offer if you’re simply willing to look around.

As I mentioned, there are a few areas where software on Linux can use some work. LockerGnome’s Ryan Pierson, in particular, wishes the video editing solutions on Linux were more competitive to the Windows and OS X market. Like I said, they exist, but they’re no Sony Vegas or Adobe Premier. When will the situation get better? It’ll have to wait for either: a] the developers of the open source alternatives to get more free time on their hands (unlikely) or b] for the commercial developers to pay more attention to Linux.

When will this attention arrive? I personally think the arrival of Valve’s Steam platform, Valve’s collection of games running on the Source engine, as well as Unity’s newly baked Linux support, will start the ball rolling. More games on Linux means gamers will start to see the platform as a useful, free alternative to Windows. As the desktop Linux market share increases as a result, more companies will consider developing ports of their software for Linux. It’s a snowball effect that I hope happens soon.

Misconception #4: Linux has a small market share

This was a fun one to read about on Engadget. Apparently, Linus’ “school project” that is Linux has failed to gain any market share for all the computers in the world whatsoever, and he should just give up and call it quits. What the ill-informed do not understand is that, quite frankly, Linux dominates computers everywhere. More than 90% of the world’s Top 500 supercomputers run a Linux-based operating system. Over half of all mobile smartphone devices now run Android, which is built on top of the Linux kernel. In addition, more than 60% of Web servers are running on a Linux distribution.

Only in the desktop space has Linux yet to leave its mark. Like I mentioned in the previous section, I expect the arrival of Steam, Source, and other gaming platforms to help boost Linux’s desktop market share considerably. Let’s hope so, anyway.

Misconception #5: Linux is only for developers and computer “experts” (aka Linux distributions are too hard to use)

This one is kind of silly. Granted, I am a developer and have been using Linux for many, many years now (since I was ten years old, at least), but the ease of use of Linux distributions has improved drastically over the years. Ubuntu, specifically, has helped make desktop Linux usable enough for ordinary human beings, as per its motto. Like I said, the software is there, so all it takes is getting used to a slightly different desktop environment when switching from OS X or Windows. I dual boot Windows and Debian here, and I hardly ever touch Windows anymore; Linux distributions have come far enough to be my daily driver from here on out.

I think Linux distributions can be intimidating and scary. I get it, though; new and different things naturally repel most of us (I’m a certified creature of habit, I’ll have you know). Many people shrug Linux off as difficult to use because they haven’t spent the time with it that it really deserves. Spend a couple of days trying to get your workflow up and running on a Linux distribution and see how you like it. Perhaps then you’ll gain a different perspective.

Our Final Push: ACTA Vote In Ten Days, Mail The European Parliament - Falkvinge on Infopolicy

Our Final Push: ACTA Vote In Ten Days, Mail The European Parliament - Falkvinge on Infopolicy | Linux A Future | Scoop.it

Ten days from today, on July 4, the European Parliament will vote on ACTA. This is the end-of-level boss; this is where ACTA lives or dies. We have won in five out of five committees – it is time for one huge final push.

Every Member of European Parliament (MEP) and assistant I have spoken to have said the same thing – the calls and mails from ordinary, concerned citizens have made all the difference. This is not obvious when looking from the outside, but as I walked around in the European Parliament last week, that impression was stronger than I had ever anticipated.

As the final vote approaches, scheduled for July 4, it is easy to let your guard down. But this is when all the trickery happens. The battle of ACTA is not over: it will be over in ten days, but not before.

It can be hard to know what to write to a MEP to make your voice heard. Believe it or not, they are people like you and me, and so, they react like you and me would to mails they receive. You don’t have to be a legal political expert to voice your concern: to the contrary, writing exactly what you feel is often the most effective way to come across.
