Earlier this week, Jiri Tlach successfully defended his truly exciting master thesis in which he describes what it takes to modify a microkernel-based operating system designed with MMU in mind to run on a processor without MMU. If you can read Czech, you can enjoy Jiri's thesis here.

It is that time of the year again when fresh graduates from the Charles University publish their defended HelenOS master theses. Visit our documentation page to read about Lenka's, Tomas' and Stanislav's work in areas as diverse as device drivers, task snapshotting and system monitoring.

During the just concluded HelenOS Camp 2010, Jiri Svoboda managed to get HelenOS running on the Neo FreeRunner smart phone. In doing so, Jiri discovered and fixed several hard to find occurrences of instruction sequences that the ARM architecture ... [More] treats as unpredictable. Unsurprisingly, these were caught by the attempt to run HelenOS on the real ARM hardware, which is much more sensitive to undefined behavior than any of the two simulators we have been using so far. At the moment, the port is lacking some way of input, but other than that, it is on par with the other HelenOS ports. Of course, one can't make phone calls from it, but as soon as we have some input driver, it will be possible to ping localhost, play tetris or do all the other stuff that people can do with HelenOS.

After seven months since the previous release, the HelenOS team is proud to announce the immediate availability of our newest and greatest release: HelenOS 0.4.2 codenamed Skewer. This version fixes many bugs and introduces many new features such as ... [More] a modular TCP/IP networking stack, support for the UltraSPARC T1 and T2 processors, improved debugging capabilities and of course a couple of new servers and applications. A more detailed summary can be found in our release notes. [Less]

According to our roadmap, the next release, which is not that far away, will introduce support for the sun4v sub-architecture of sparc64, and the long awaited and wished-for TCP/IP networking stack. Early adopters and testers can preview both features in their staging branches (sun4v and networking).
