 libgtop is a library used by many applications (especially GNOME applications)
 to abstract the system-specific methods for obtaining information about the
 current state of the system -- processes running, system load etc.

+I just read on the hurd IRC channel (chat: #hurd at irc.freenode.net), that people consider my work valuable (I knew that, and I think that myself, but it is still nice to hear), so I want to dispell any possible myth about it :)
+
+What I do is not hard - at least not anymore, since I created a simple structure for it (But it still takes time).
+
+First I open up the relevant mailing lists for the quarter. I get them from [[contributing/web_pages/news/writing_the_qoth]]. Normally I just use the following:
+
+* <http://lists.gnu.org/archive/html/bug-hurd/YYYY-MM/threads.html>
+* <http://lists.debian.org/debian-hurd/YYYY/MM/>
+
+Then I copy them 3 times and use M-x replace-string (in emacs) to adjust them to the correct months.
+
+Additionally I open the Arch Hurd news:
+
+* <http://www.archhurd.org/news.php>
+* <http://planet.archhurd.org/>
+
+Having all those news at hand, I read every thread-starter and every news-item. For each of them I first check if I understand them (no use trying to explain something I don’t get myself) and if they provide a way for people to test what they improved (however complex that might be), then I 
+
+* note the name of the main contributor(-s), 
+* write a line of text what it does (often partly copied from the news-item),
+* add a link to the news-item, a code-repo or a patch and
+* a note how that new development helps achieve the goals_of_the_Hurd (see [[contributing/web_pages/news/writing_the_qoth]] for details).
+
+With that list of short news I go into [[contributing/web_pages/news/qoth_next]]. 
+
+Now I identify 2 to 4 main news items by some kind of “helps the Hurd most when more people know it”, “biggest change” and similar fudgery :)
+
+Finally I sort all the news items by intuition, crude logic I develop on-the-fly writing and the goal of making the qoth read somewhat like nice prose. 
+
+On the way to that I commit every little to medium step. I never know when I have to abort due to an interruption (I’m sure tschwinge loves my super-non-atomic horrible-to-review commits :-) - but better that than losing work == time, and I try to prefix the commit-messages with “news:” so he knows that it’s useless to review them as in-flight-patches…).
+
+Having finished the text (usually after 3 to 6 hours of overall work), I send it by mail to bug-hurd: <http://lists.gnu.org/archive/html/bug-hurd/>
+
+After about a week I incorporate the comments from there and publish the qoth as described in [[contributing/web_pages/news/writing_the_qoth]].
+
+Then tschwinge reviews it, does some last-minute changes and pushes it from the staging wiki to the website.
+
+And that’s it.
+
+I hope this small insight was interesting to you. Happy hacking and have fun with the Hurd!
+
+-- Arne Babenhauserheide
+
+PS: Writing this blog entry took about 20 minutes. The raw text is longer than a qoth, but it is much faster to write, because it avoids the main time-eater: Gathering the info with the necessary references to make sure that people can test what’s in here.

+#GSoC 2012 - Disk I/O Performance Tuning 
+
+15.06.12
+
+Explored gnumach code. First I was reimplementing vm_fault_page as coroutine that returns before executing of mo_data_{unlock,request} calls to vm_fault. vm_fault had to analyse state of vm_fault_page for every page in loop and make a decision regarding further behavior (call mo_data_*, go to next page, etc.). But than I've got that this way is much worse, than doing everything in vm_fault_page (like in OSF mach), so I made a back-off and started working on clustered paging from the beginning (at least now I see clearer how things should be). At the moment I review kam's patch one more time and looked through mklinux code attentively.
+
+8.06.12
+
+Applied Neal's patch that reworks libpager, changed libdiskfs, tmpfs and ext2fs according to new interface. ext2fs isn't finished yet and should be reworked, but looks like I brought some bug to existing implementation and i want first to fix it and than finish rest of ext2fs. Also I pushed some code changes to hurd git repository into my branch mplaneta/gsoc12/working. Now I start working on gnumach implementation of clustered page reading. After this I'm going to implement madvise, than finish ext2fs and start porting of other translators.
+
+14.05.12
+
+First of all I'm going to do 2 programs. First will work as server, it will create an object and share it with second. Second will try to access to this object. This will cause page fault and kernel will refer to first program (server). This way I will be able to track how page faults are resolved and this will help me in debugging of readahead. IFR: server probably can use some of hurd's libraries, but it has to handle m_o_* RPC's on it's own. TODO: Find out how supply second program (client) with new object. NB: be sure that client will cause page fault, so that server always will be called (probably any caching should be disabled).
