The just released version 12.08 of the Genode OS Framework comes with the ability to run Genode-based systems on ARM hardware without an underlying kernel, vastly improves the support for the NOVA hypervisor, and adds device drivers for the OMAP4 SoC. Further functional additions are a FFAT-based file system service, the port of the lighttpd web server, and support for on-target debugging via GDB.

"So in summary... Google has pulled the plug on support on a protocol they've helped popularize, after years of promising interoperability, for reasons that are dubious at best, and in a way that leaves people who don't jump to the new Hangouts app unable to talk to their contacts without any feedback that their IMs aren't getting through... And they've done that with no warning to anyone. I imagine there's a bunch of people out there wondering where some of their buddies have gone, or why their messages aren't getting responses, because this isn't documented anywhere." Google really messed this up. Such a dick move.

The Tizen Greek Community has some screenshots of a very recent build of Tizen running on a Samsung GT-i8800. It looks wholly unremarkable.

Joint statement to The Next Web from Microsoft and Google: "Microsoft and YouTube are working together to update the new YouTube for Windows Phone app to enable compliance with YouTube's API terms of service, including enabling ads, in the coming weeks. Microsoft will replace the existing YouTube app in Windows Phone Store with the previous version during this time." Good to know these children stopped acting like little pricks. Can we have full Google support in Windows 8 now, please?

Yahoo is acquiring Tumblr, the microblogging and social networking website, for $1.1 billion USD. Tumblr offers little revenue but lots of eyeballs if Yahoo can monetarize them. Now Yahoo is bidding for Hulu, the streaming video service. After years of ineffective responses while Google, Facebook, and others took large chunks of the online advertising market, Yahoo is fighting back. Can Yahoo reignite the momentum it had at the turn of the century? What do you think?

"Sources have described iOS 7 as 'black, white, and flat all over'. This refers to the dropping of heavy textures and the addition of several new black and white user interface elements." I couldn't be happier.

"Ilja van Sprundel, a security researcher with IOActive, has discovered a large number of issues in the way various X client libraries handle the responses they receive from servers, and has worked with X.Org's security team to analyze, confirm, and fix these issues."

"Google is facing a new antitrust probe by the U.S. Federal Trade Commission into whether the company is using its leadership in the online display-advertising market to illegally curb competition, people familiar with the matter said." Sucks to be Google today, apparently.

"In the midst of the major press blitz surrounding its annual I/O Conference, Google dropped some unfortunate news about its instant messaging plans. In several places around the web, the company is replacing the existing 'Talk' platform with a new one called 'Hangouts' that sharply diminishes support for the open messaging protocol known as XMPP (or sometimes informally Jabber), and also removes the option to disable the archiving of all chat communications. These changes represent a switch from open protocols to proprietary ones, and a clear step backward for many users." That's why I always say: only suckers trust companies.

"The wave of departures is a sign of internal struggle, but amidst all the bad news, there is a glimmer of hope. According to an anonymous HTC executive cited by WSJ, the crucial HTC One is selling 'pretty good so far'. The executive revealed that HTC sold about five million One units since launch, a performance that is deemed encouraging. However, sales have been limited by the persisting supply issues that still plague the production of the HTC One." Finally some good news for HTC. Five million units amidst supply constraints is very impressive.

"Sony gave the PS4 50% more raw shader performance, plain and simple (768 SPs @ 800MHz vs. 1152 SPs & 800MHz). Unlike last generation, you don't need to be some sort of Jedi to extract the PS4's potential here. The Xbox One and PS4 architectures are quite similar, Sony just has more hardware under the hood. Weâll have to wait and see how this hardware delta gets exposed in games over time, but the gap is definitely there. The funny thing about game consoles is that itâs usually the lowest common denominator that determines the bulk of the experience across all platforms. On the plus side, the Xbox One should enjoy better power/thermal characteristics compared to the PlayStation 4. Even compared to the Xbox 360 we should see improvement in many use cases thanks to modern power management techniques." AnandTech does its usual in-depth thing.More News »

Apparently, the redundancies between the microkernel and the first user-land component (mostly called root task) have been somehow overlooked for years now. Not just in the context of Genode but in multi-server OS projects in general. I guess the reason is that both kind of programs used to be developed by distinct groups of people. Boldly generalizing, I think that kernel developers love to stay in kernel land. Their view is somehow narrowed to the kernel API and hardly extend to a holistic system. On the other hand, user-land developers do not challenge kernel APIs too much (similar to how most software developers rarely question the hardware interfaces underneath their software).
Personally, I find the result of the base-hw experiment quite fascinating. It shows that dissolving the barrier between thinking in categories of kernel land and user land bears the opportunity for simplifying the overall architecture.
I share your observation about several of the base platforms. The motivation for keeping them around slightly differ from kernel to kernel. For Codezero, we are still hoping for a relaunch of the kernel as an Open-Source project. Pistachio is actually still maintained. For all of those kernels, there are also common reasons to not abandon them.
First, its beneficial for Genode's API design. Each kernel poses different challenges with regard to implementing the API. By accommodating a variety of kernel interfaces, we constantly reassure the portability of the framework and force ourself to find clean solutions that work across all of the kernels.
Second, having an arsenal of kernels at our disposal is just great for cross-correlating the behaviour of the system during debugging. Many bugs can be tracked down by just looking at the differences of executing the same scenario on different platforms. In fact, at Genode Labs we are constantly switching between the kernels including the ancient L4/Fiasco kernel. As a bonus, several of the kernels offer unique debugging features, which become pretty handy from time to time.
Third, maintaining support for an already supported base platform is cheap. It comes down to maintaining approximately 2000-3000 lines of code per kernel. For a kernel that won't move, the maintenance costs are almost zero (except for changes of the Genode API).
