Late last year Australia's biggest telco Telstra was sharply criticised for using GPL'd code in several of its new products - but not publicly distributing changes it made to the code when doing so. However, it looks as though the company has now come clean, publishing a source code CD of the files changed in its development effort and acknowledging the GPL and Lesser GPL. It's good to see companies responding to the open source community this way and engaging - makes a change from the past!

George Hotz is in the middle of what could be a long, punishing legal battle with Sony, and his money is running out. "Media, I need your help. This is the first time I have ever asked. Please, if you support this cause, help me out and spread the word," he wrote on his newest blog entry. "I want, by the time this goes to trial, to have Sony facing some of the hardest hitting lawyers in the business. Together, we can help fix the system." Ars Technica contacted Hotz's lawyer to make sure this plea for cash was legitimate, and attorney Stewart Kellar confirmed that yes, the money raised goes to Hotz's legal fund to fight Sony. It also appears Hotz has friends with deep pockets; the first round of fundraising is already over, and more lawyers will be hired for Hotz's defense."

Okay, source material is more than 10 years old so this is not exactly news, but I think it's interesting anyway. This BeOS promotional video is a good reminder of how powerful modern hardware truly is, what hardware should be needed for light computer use, and how laughable modern desktop&mobile OSs are as far as performance is concerned. Here are part 1 and part 2 on YouTube.

"A lot of modern Linux distributions created with desktop users in mind go out of their way to be user friendly. Ubuntu, Mint, openSUSE, Fedora - and many more. It is a sign of how desktop Linux has matured that even non-techy types can get a fully featured and easy-to-use open source operating system up and running in not much time at all. The creators of CrunchBang Linux, however, haven't quite gone in the same direction."

"AT&T chief Randall Stephenson in an event at Mobile World Congress on Tuesday called for a system that let users keep app ownership across platforms . He argued it was frustrating that buying an app on one platform didn't give you the rights to the app on another. He saw solutions such as the Wholesale Applications Community (WAC) or HTML5 as being better models, although few phones actually support WAC or use HTML5 in a major way for apps."

In the description of this session of SXSW 2011: Voices From The HTML5 Trenches: Browser Wars IV, it says: "Every major browser vendor -- Apple, Opera, IE, Chrome, and Firefox -- will have a significant browser release by SxSW 2011." IE team has confirmed it by an annouchment, now we can wait and see if IE9, Firefox 4, Chrome 10, Opera Mini 6 for Tablets and Safari (???) will be released all together.

"PCLinuxOS is a great distro for individuals who favor rolling updates, performance, and a dedicated community. If you're a first-time Linux user or if you favor aesthetics over technological prowess, better choices are available."

Well, well, well. We all know Apple's App Store policies are incompatible with the GPL, and as such, software using this license can't be distributed in the App Store. So, what about Microsoft's Windows Phone 7 Marketplace? Well, whereas the App Store doesn't specifically mention the GPL (Apple's terms are simply incompatible), Microsoft drops the pretence and simply bans GPL and GPL-esque licenses outright.

"Samsung Electronics has announced the bada 2.0 smartphone platform with support for near field communication (NFC), HTML5, the Wholesale Applications Community, multitasking and voice recognition. According to Samsung, bada 2.0 also comes with a new and improved software development kit (SDK) that opens up the platform to more developers working across different PC operating systems."

"Here in the Android-watching world, the air has smelled of uncertainty for quite some time. Ever since Google announced Android Honeycomb, the tablet-optimized edition of its mobile OS, there's been no shortage of questions about the platform's future and the direction in which it's headed Thanks to some revelations made at this week's Mobile World Congress, we're finally getting some firm answers ."

A new open source project hopes to take Android and change it so it has a clean-room OpenJDK-based Java VM and will be based on what they refer to as a more standard Linux kernel. Meanwhile, rumor has it that RIM is considering using somebody's Java VM to run Android apps, but it won't be Dalvik.
