	<content:encoded>&lt;p&gt;Od jakiegoś miesiąca uczę się fińskiego, język ciekawy, ale dość trudny ( 16 przypadków, slowko &amp;#8216;nie&amp;#8217; odmienia sie przez osoby, itd. ). Zamieszczę kilka pomocnych linków z których korzystam:&lt;/p&gt;
&lt;p&gt;Super słownik internetowy: &lt;a href=&quot;http://www.ilmainensanakirja.fi/&quot;&gt;Ilmainen Sanakirja&lt;/a&gt;&lt;br /&gt;
Drugi słownik: &lt;a href=&quot;http://www.kaannos.com/&quot;&gt;Kaanos&lt;/a&gt;&lt;br /&gt;

	<content:encoded>&lt;p&gt;The book meme is still alive, so once again:&lt;br /&gt;&lt;ul&gt;&lt;li&gt;Grab the nearest book.&lt;/li&gt;&lt;li&gt;Open it to page 56.&lt;/li&gt;&lt;li&gt;Find the fifth sentence.&lt;/li&gt;&lt;li&gt;Post the text of the sentence in your journal along with these instructions.&lt;/li&gt;&lt;li&gt;Don’t dig for your favorite book, the cool book, or the intellectual one: pick the CLOSEST.&lt;/li&gt;&lt;/ul&gt;&lt;span&gt;&quot;When the QLabels are added to the status bar, they are automatically reparented to make them children of the status bar.&quot;&lt;/span&gt;&lt;br /&gt;&lt;/p&gt;&lt;br /&gt;&lt;p&gt;&lt;br /&gt;And the winner is &quot;C++ GUI Programming with Qt 4&quot; second edition by Jasmin Blanchette and Mark Summerfield. Thank &amp;lt;deity&amp;gt; this wasn't &quot;ANSI C&quot; by Kernighan and Ritchie which is lying beneath the Qt book, but sadly Stanisław Lem's &quot;Tales of Pirx the Pilot&quot; where to far away, although also on top of another stack of books&lt;br /&gt;&lt;/p&gt;&lt;br /&gt;&lt;p&gt;Looks like &lt;a href=&quot;http://mark.doffman.com/index.php/2008/11/13/the-book-meme/&quot; title=&quot;Mark Doffman's blog&quot;&gt;Mark D.&lt;/a&gt; is right - we all are depressingly geeky...&lt;/p&gt;</content:encoded>

	<title>Tomasz Wendlandt (juggler): Local DoS on Linux 2.6.27.4</title>
	<link>http://wendlandt.pl/local-dos-on-linux-26275/</link>
	<content:encoded>&lt;p&gt;Ostatnio &lt;a href=&quot;http://wendlandt.pl/page-cache-on-linux-2627&quot;&gt;pisałem&lt;/a&gt; o kernelu 2.6.27. Okazuje się, że od paru dni krąży exploit pozwalający na lokalny atak denial of service na wersje starsze niż 2.6.27.5 .&lt;/p&gt;
&lt;p&gt;&lt;code&gt;The __scm_destroy function in net/core/scm.c in the Linux kernel 2.6.27.4, 2.6.26, and earlier makes indirect recursive calls to itself through calls to the fput function, which allows local users to cause a denial of service (panic) via vectors related to sending an SCM_RIGHTS message through a UNIX domain socket and closing file descriptors.&lt;/code&gt;&lt;/p&gt;

	<title>Tomasz Wendlandt (juggler): page cache on Linux 2.6.27</title>
	<link>http://wendlandt.pl/page-cache-on-linux-2627/</link>
	<content:encoded>&lt;p&gt;Miesiąc temu wydano &lt;a href=&quot;http://kernel.org/&quot;&gt;kernel&lt;/a&gt; 2.6.27, m.in. usprawniono w nim obsługę page cache&amp;#8217;u dla systemów wieloprocesorowych. Ciekawe jak bardzo nowa funkcja &lt;em&gt;get_user_pages_fast()&lt;/em&gt; potrafi poprawić wydajność systemu, może ktoś już to testował?&lt;/p&gt;
&lt;p&gt;&lt;code&gt;The page cache is the place where the kernel keeps in RAM a copy of a file to improve performance by avoiding disk I/O when the data that needs to be read is already on RAM. Each &amp;quot;mapping&amp;quot;, which is the data structure that keeps track of the correspondence between a file and the page cache, is SMP-safe thanks to its own lock. So when different processes in different CPUs access different files, there&amp;#039;s no lock contention, but if they access the same file (shared libraries or shared data files for example), they can hit some contention on that lock. In 2.6.27, thanks to some rules on how the page cache can be used and the usage of RCU, the page cache will be able to do lookups (ie., &amp;quot;read&amp;quot; the page cache) without needing to take the mapping lock, and hence&lt;br /&gt;
improving scalability. But it will only be noticeable on systems with lots of cpus (page fault speedup of 250x on a 64 way system have been measured).&lt;br /&gt;
&amp;nbsp;&lt;br /&gt;
In 2.6.27, a new get_user_pages_fast() function has been introduced, which does the same work that get_user_pages() does, but its simplified to speed up the most common workloads that exercise those paths within the same address space. This new function can avoid taking the mmap_sem semaphore and the page table locks in those cases. Benchmarks showed a 10% speedup running a OLTP workload with a IBM DB2 database in a quad-core system.&lt;/code&gt;&lt;/p&gt;

	<link>http://pieter.pl/2008/11/01/zeberka-w-sosie-barbecue/</link>
	<content:encoded>&lt;p&gt; 	Tym razem coś czasochłonnego i niełatwego, za to dość tanio i bardzo smacznie :-) Jest sporo różnych przepisów na żeberka w sosie BBQ. Ja pozbierałem część z nich i wybrałem sobie to, co wydawało mi się najsmaczniejsze. Zapraszam do testowania - oto przepis dla dwóch osób: &lt;a href=&quot;http://pieter.pl/2008/11/01/zeberka-w-sosie-barbecue/#more-169&quot; class=&quot;more-link&quot;&gt;(more&amp;#8230;)&lt;/a&gt;&lt;/p&gt;</content:encoded>

	<link>http://princefool.blogspot.com/2008/09/end-of-era.html</link>
	<content:encoded>&lt;p&gt;In a few weeks I'll be shutting down my home server (please don't start the discussion about the definition of a server again!). This means that my current XMPP account will cease to exist and it will be reinstalled at a new server (probably Google Apps); so please forgive me if you get some auth requests.&lt;/p&gt;</content:encoded>
