Chemnitzer Linuxtage 2013 am Wochenende 16. & 17. März

Chemnitzer Linux-Tage 16./17. März 2013

Auch dieses Jahr möchte ich kurz auf die Chemnitzer Linuxtage hinweisen, die wieder ein volles Programm im Bereich Linux und (Free Libre) Open Source Software haben. Einige der Themen:

Neben weiteren Vorträgen gibt es noch Workshops zu Inkspace, LibreOffice, Python & Django, LaTeX, Rasperry Pi und mehr. Wer nicht direkt vor Ort sein kann, hat die Möglichkeit per Audio- oder Videostream teilzunehmen.

Software Wars: movie about how free software will save the world

> The average computer user is unaware there is a war for freedom going on that will determine the path of modern society. Software Wars is a movie about the battle for our right to share technology and ideas. This software will not be ‘owned’ by corporations like Microsoft, Apple, and Google, who are mostly impeding technological progress.Source: Software Wars @ indiegogo

> The main producer is Keith Curtis, a Seattle-based author and programmer who spent 11 years at Microsoft before being converted to the world of Linux and open-source software. The movie is based on a portion of Curtis’ book, “After the Software Wars,” but he’s working on the project with an extensive virtual team out of L.A. — Source: GeekWire

I already had Curtis’ book from 2009 on my list “20 Free Books on Linux, Open Source Software & Philosophy.”

I wondering if that movie is going to be a objective documentary about the subjects Free Libre Open Source Software (FLOSS) and proprietary systems. I guess it won’t be like that. But at least it could be a movie nice to watch, and it can be used in campaigns for free software projects and as an opposite to proprietary software campaigns that people usually watch every day at TV/commercial breaks.

So let us support the crowdfunding campaign of Software Wars.

PubwichFork 2.1 released

7 months after version 2.0, the new PubwichFork 2.1 comes with improved support for responsive mobile layouts and updated social media service classes.

After saving original Pubwich from death, PubwichFork 2.0 was downloaded appr. 350 times, installs from the repository not included, it attracted attention in some weblogs for web developers, PubwichFork powered sites were shown on barcamps and featured in a professional journal.

Now PubwichFork 2.1 comes with some minor but nice improvements.

Download and installation

That’s easy! Just download the PubwichFork 2.1 archive (we provide Zip and Tar), unpack it in your webspace and follow the config instructions from the manual.

Improvements made in PubwichFork 2.1

Check the changelog for a detailed list of changes.


About PubwichFork

PubwichFork aggregates your latest Social Web and Social Media content across multiple service websites, e.g. your Twitter stream or Flickr photos. Then it renders one single website featuring all your content. PubwichFork is written in PHP and licensed Open-Source under a GPL.

PubwichFork was featured in WebResourcesDepot, La Ferme du Web, PHPspot and Hot Scripts Blog. (only to ping that sites about this realease :)

Zend Framework 2

A little bit more than a month ago Zend Framework 2 stable finally has be seen the light, after all the years of development it was finished earlier than the new Berlin Airport, a never ending story and source for jokes :)

Zend put a new website online and used new URIs for downloads but it seems that they forgot to set redirects, so some install routine of Zend Framework enabled software had to get updated.

Everyone who wants to dive into the new version of the well known PHP framework, check out those nice resources out there:

Since the first release of ZF2, the developer community released two more minor bugfix releases: recent version is 2.0.2.

PubwichFork im Screenguide #15 und warum FLOSS nicht totzukriegen ist

In der aktuellen Ausgabe 15 des Screenguide Magazins wird auch ein Screenshot eines Social Media Newsroom gezeigt, welcher mit PubwichFork realisiert wurde. Leider das freie Softwareprojekt für tot erklärt, was natürlich Quatsch ist. Im Gegensatz zu proprietärer Software kann Software mit freien Lizenzen auch überleben, wenn der Entwickler nicht mehr aktiv ist.

Michael Zinkl von EQS beschreibt im Artikel “Website als Newsroom” Möglichkeiten, um (Firmen-) Aktivitäten innerhalb von Sozialen Netzwerken auch wieder auf der eigenen Webseite zu präsentieren und dadurch auch mehr Möglichkeiten bei der Präsentation dieser Inhalte zu haben. Der im Artikel beschriebene Ansatz beinhaltet das Sammeln der einzelnen Aktivitäten über die von den verschiedenen Social Media Services zur Verfügung gestellten Schnittstellen wie REST-APIs und RSS-Feeds. Auch der Newsroom von Troisdorf, welcher mit PubwichFork realisiert ist, wird als Beispiel im Artikel mit einem Screenshot vorgestellt.

Als softwareseitige Unterstützung zum Aufbau eines eigenen Newsrooms wird unter anderem der Social Media Newsroom der EQS Group vorgestellt. Auch Pubwich wird kurz erwähnt, leider nur mit folgender Aussage, die falsch ist:

Pubwich ist eine Open-Source-Alternative, die kostenlos zur Verfügung steht, jedoch seit 2010 nicht mehr weiterentwickelt wird.

Es ist zwar richtig, dass sich der ursprüngliche Autor und Gründer des Pubwich-Projekts seit 2010 aus der aktiven Entwicklung zurückgezogen hat, deswegen ist Pubwich aber noch lange nicht tot. Seit Mai 2011 gibt es einen Fork von Pubwich, welcher weiterhin aktiv entwickelt wird. PubwichFork steht kurz vor der Veröffentlichung von Version 2.1. Dies hätte man auch leicht über Google oder im Github-Profil von Pubwich herausfinden.

Ich möchte hier niemanden unterstellen, dass die FLOSS-Alternative im Bereich Social-Newsroom-Software für tot erklärt wird, um das eigene proprietäre Produkt besser promoten zu können. Ich gehe eher davon aus, dass leider einfach immer noch nicht die Vorteile von quelloffener Software unter freien Lizenzen verstanden wurden.

Im Gegensatz zu proprietärer Software kann freie Software auch weiterentwickelt werden, wenn der Hersteller oder Hauptautor den Support für die Software eintellt. Proprietäre Software hingegen wäre an dieser Stelle wirklich tot, FreeHand ist dafür ein sehr populäres Beispiel. Nutzer dieser Software haben ein Problem, wenn sie auf die Software angewiesen sind. Im Bereich freier Software ist es dagegen möglich, dass die Software von anderen Parteien übernommen und weiterentwickelt ist, unabhängig wie gut oder schlecht das Projekt geschrieben und dokumentiert ist. Die Möglichkeit ist vorhanden — und wurde im Falle von Pubwich auch genutzt.

Wer mithelfen möchte, PubwichFork weiterhin aktiv und lebendig bleibt, ist herzlich eingeladen:

Tears of Steel: He just wanted to be awesome in space!

Yesterday Blender Foundation released director Ian Hubert’s new short film Tears of Steel, a movie about a group of warriors and scientists, who gather at the “Oude Kerk” in Amsterdam to stage a crucial event from the past, in a desperate attempt to rescue the world from destructive robots.

The 4th movie of the Blender foundation, after Elephants Dream (2006), Big Buck Bunny (2008), and Sintel (2010), is not fully trick animated, it’s a mix between real places and actors and CGI animation. It doesn’t matter if you like or not like the story and actors, the movies really shows what is possible with free software and volunteers. The movie was financed by Blender’s user community, the Netherlands Film Fund, the Cinegrid consortium, and by corporate sponsors such as Google.

Currently you can watch Tears of Steel online via YouTube, download and torrent links will be provided soon, when mirrors have been synced. A DVD release is planned with a lot of additional features, e.g. all sources.

Tears of Steel is released under the terms of the Creative Commons Attribution 3.0 license.

Fun fact: the movie project name was/is Mango, the soldier in the movie drinks mango juice.

20 Free Books on Linux, Open Source Software & Philosophy

Very often we only need some quick tips and tutorials to solve our problems. Nethertheless it is still great to dive in deeper, get a wider background of knowledge. So, books are still great.

This list is based on three compilation done by Linux Mint tumblr and my bookmarks about books.

All of the book are free, at least free as in free beer. Some of them are licensed under a free and open license. Most of the books are available in various ebook formats and paper versions, please consider to buy one if you like it. Now, enjoy the list:

Thank you for talking about PubwichFork!

You need to attract people to make Open Source software projects successful. That’s the reason why I wanna say thank you to everybody who spread the message about PubwichFork. You are as important as the software itself.

Creating an Open Source software project is easy, getting attention is hard because we have so many great software projects. Small FLOSS projects do not have budget to buy commercial advertising, neither they have a big community at the beginning — they live on word-of-mouth recommendations.

WebResourcesDepot, La Ferme du Web and PHPspot introduced PubwichFork to their readers after the PubwichFork 2.0 was released. Recently the Hot Scripts Blog list it in their top three most popular social wall scripts.

I want to thank especially every single person who tweeted and bookmarked it, contributed feature requests and bug reports.

Please keep it on! Do not stop spreading the word. It’s important!

Open Source by numbers: Measuring activity of FLOSS projects

I probably wrote it before: Free Libre Open Source Software (FLOSS) rules. The FLOSS ecosystem seems to be well grown and it don’t stop beeing active, even if not all projects are outstanding like the Linux kernel. Let’s check the numbers.

Rich Sands from Ohloh/BlackDuck made some analytics on open source projects, he gave a talk at Linux Collaboration Summit and wrote a blog post about his findings.

The quick facts from the “Open Source By The Numbers” slides are (maybe truth is forged by my interpretation):

  • Github: over 4.75 mio repositories
  • Sourceforge lost importance: “only” 324.000 projects
  • Ohloh: more than a half million projects are listed (appr. 50% of them were used for the statistics)
  • project “liveness” could be measured in recent code changes and team size
  • only a bit more that 1/6 of all projects on Ohloh made code commits in the last year
  • GNOME activity is little behind KDE (euphoristic view: GNOME needs fewer bug fixes)
  • too many Java developers out there :)
  • Python, PHP and Javascript attracting more people now than 5 years ago
  • small projects prefered for contributions and participation
  • long-term traction is the lottery win

Btw, personal stats: I got my Ohloh profile almost 5 years ago, it is related to 12 projects, Ohloh ranks me on #8323, with 815 total commits, 135.120 lines changes and a comment ratio of 20.4%. Join me there, maybe on Foafpress or PubwichFork.

FLOSS makes the world go round: How Linux is built, and why you should use it!

While Linux is running our phones, friend requests, tweets, financial trades, ATMs and more, most of us don’t know how it’s actually built. This short video takes you inside the process by which the largest collaborative development project in the history of computing is organized.

Based on the annual report “Who Writes Linux,” this is a powerful and inspiring story of how Linux has become a community-driven phenomenon.

Some key facts are:

  • over 850.000 Android phones, running Linux, are activated every single day (compared to 30.000 Windows phones)
  • 9 out of 10 super computers run Linux
  • powered by Linux tech stack: Google, Facebook, Twitter, Amazon
  • Linux is the largest collaborative development project in the history of computing
  • since 2005: 8000 developers contributed to the Linux kernel
  • 1.5 mio lines of code in the last couple of years
  • a new Kernel version comes out every 2 or 3 months
  • 10.000 patches inserted in every new release
  • 6 patches are applied to the kernel each hour

I don’t think that this could be accomplished by a single company with a proprietary operating system. The numbers are huge, unbelievable.

The “Linux is hard to use” urban story

On the Youtube page of the video someone commented:

Linux may be great for such specific uses, but in the end what weighs windows out is the user-friendly-ness which linux lacks, and thus most common base applications are designed for windows and alot don’t even have linux versions. I’ll definitely stick to windows so far as I don’t have need of those special funcitonalities. (commented by AlexGliesch)

This probably is a widely spread opinion if it comes to decide about the usage of a Linux. And do you know what: It is wrong!

Linux is only the kernel, but there are a lot of different Linux distributions you can choose to use as OS. If you install a Linux distribution like Fedora or Ubuntu, you will see that everything will work easier than in WinXP or Win7. Network configuration? Easier! Office programs? Already installed! And so on … It’s a lie that the most common base apps are just developed for Windows, you always have an available replacement under Linux, sometimes it is even better to use. Other applications are developed to work under different systems. If it comes to gaming, it may be another situation, even if Linux users like gaming.

A friend told me that she really loves the possibility to use different desktops on her new Mac, and that she is not forced to have all open application on one single desktop like within MS Windows. Most Linux desktops like Gnome, KDE and Xfce have this feature built in since ages. Windows anyone?

One problem is: if you buy a PC or Laptop, most times it comes with a pre-installed Windows. So, nobody really makes a choise for using Windows, they just accept it. If a new PC/Notebook would be shipped with a pre-installed Linux distro, people could see how easy it is to use for the average daily tasks.

So, if you are one of the cool guys, then try one of the available Linux distributions, and see yourself that the “user-friendly-ness which linux lacks”-mantra is just bullshit!

The video was made by The Linux Foundation.

The Linux Foundation is a nonprofit consortium dedicated to fostering the growth of Linux. Founded in 2000, the organization sponsors the work of Linux creator Linus Torvalds and promotes, protects and advances the Linux operating system by marshaling the resources of its members and the open source development community. The Linux Foundation provides a neutral forum for collaboration and education by hosting Linux conferences, including LinuxCon, and generating original Linux research and content that advances the understanding of the Linux platform.
