First branded as a communist plot, then derided as a form of cancer, before being upgraded to merely a 'grey spectre', free and open source software (FOSS) has had a pretty rough ride from Microsoft over the years. For many in the open source community, the company represents all that is troubling about closed source software development. Recently, though, there have been developments that at least one leading open source developer has labelled a 'sea change' following last year's announcement that Microsoft was to become sponsors of the Apache Software Foundation (ASF).

Web code is already open - why not make it free as well

 

http://www.freesoftwaremagazine.com/columns/web_code_already_open_why_not_make_it_free

 

Oh dear. After the debacle with Microsoft Poland’s apparent racist photoshopping, Microsoft China went and got the company in hot water for allegedly “stealing” code. Yes you read that right: Microsoft and wholesale “theft” of code from another website. Of course it’s not “theft” it’s copyright infringement but tomayto/tomarto. Microsoft confessed blaming a vendor they had worked with. No surprise really but the damage to their name may have already been done. There’s more to discuss here than Microsoft’s already tarnished reputation though. The issue raises some important points in favour of free software and points to why more if not all code should benefit from free licencing./QUOTE]

openSUSE Brings New Li-F-E To Schools

openSUSE Packs Plenty for School Kids and Schools

 

http://www.linuxplanet.com/linuxplanet/reviews/6962/1/

 

It's a safe bet that the majority of K through 12 students in this country have access to a computer either at home or school. With education budget trends resembling a ski slope (downhill) it only makes sense to look to open source for help. With the 11.2 release of openSUSE comes a separate project targeted at schools and school children.

 

figure 1

 

openSUSE for Schools (or Linux for education aka Li-f-e) packs a huge number of applications targeted at all grade levels. Packages for both desktop and server are included. They've also provided things like Internet filtering software to help parents and educators protect kids from potential problems. For classroom use you'll find tools for creating a kiosk mode or live CD bootable on older machines.

Video, Freedom And Mozilla

 

http://weblogs.mozillazine.org/roc/archives/2010/01/video_freedom_a.html

The basic problem is simple: H.264 is encumbered by patents whose licensing is actively pursued by the MPEG-LA. If you distribute H.264 codecs in a jurisdiction where software patents are enforceable, and you haven't paid the MPEG-LA for a patent license, you are at risk of being sued.

 

So why doesn't Mozilla just license H.264 (like everybody else)? One big reason is that that would violate principles of free software that we strongly believe in. In particular, we believe that downstream recipients of our code should be able to modify and redistribute it without losing any functionality. This is freedom that copyleft licenses such as the GPL and LGPL (which we use for our code) are intended to ensure. It is possible to obtain patent licenses in a way which works around the letter of the GPLv2 and LGPLv2, but honoring the letter while violating the spirit is not a game we are interested in playing.

Microsoft Office document corruption: Testing the OOXML claims

 

http://www.robweir.com/blog/2010/02/office-document-corruption.html

 

Summary

 

In this post I take a look at Microsoft’s claims for robust data recovery with their Office Open XML (OOXML) file format. I show the results of an experiment, where I introduce random errors into documents and observe whether word processors can recover from these errors. Based on these result, I estimate data recovery rates for Word 2003 binary, OOXML and ODF documents, as loaded in Word 2007, Word 2003 and in OpenOffice.org Writer 3.2.

 

My tests suggest that the OOXML format is less robust than the Word binary or ODF formats, with no observed basis for the contrary Microsoft claims. I then discuss the reasons why this might be expected.

Insight into GNU/Linux boot process

Abstract:

Booting an operating system has always been considered a challenging task. In this document we will take a look at the different aspects of the boot process. Such as the BIOS which is the first code which runs, the boot loaders that can load different operating systems, pass arguments to the kernel, load it from different sources like a hard drive, a flash, and network & finally the kernel itself. Though loading the kernel & setting it up to execute is not all that is to be done, we need to bring the system up with different user specific configurations. We will look at the scripts, which deal with this.

Linux has grown from a system that used to boot from a floppy providing no luxurious features to the user, to the current jazzy Linux systems. It is important to have an insight of the Linux boot procedure. Say for Linux to serve the purpose on embedded systems, the generic boot procedure must almost always be modified to meet the needs of the target application.

Use Vim Like A Pro

Why Bother? (reasons)

There are many other editors, some being quite excellent. There is no reason why you cannot use one of them, however, there are some advantages in using VIM. Likewise none of these reasons are unique to VIM.

 

• With the sudden rise in Unix use (Linux and Mac OS X, in particular) the text editor known as VIM ("vi improved") has become ubiquitous
  
• Vim has a small footprint in RAM and on the CPU. A given system can support a great [* ]many VIM users at once.
  
• Vim has a lot of "superpowers", which make editing quite efficient.
  
• Vim has "geek appeal".
  
• Vim has a very active user/developer community. It always has.

[...]

 

Nobody knows all of VIM. There is enough in VIM's command system to keep thousands of human beings all using it in their own idiosyncratic way. Luckily, you don't have to know it all. You only need to know how to do your own work.

 

Because there is so much capability in this program, you will be learning new tricks as long as you continue to use it. The secret is to not settle for crummy ways of doing work.

 

VIM has word completion, and undo, and shortcuts, and abbreviations, and keyboard customization, and macros, and scripts. You can turn this into *your* editor for *your* environment. That's cool, but it's also reassuring to know that you can probably be much more productive than you are without touching any of those advanced features.

 

As Bram Moolenaar (VIM's primary author) says, the best way to learn VIM is to use it and ask questions. This little tutorial is full of questions you might not have thought to ask. That's the main value I can give you.
