Тестване бързодействието на Mysql с xfs & ext3 фаилови системи

Теста: nako@fasa:~$ mysqlslap –auto-generate-sql –concurrency=100 –iterations=5 –number-of-queries=10000

 

Резултта, при различни фаилови системи.

FS Average number of seconds to run all queries: Minimum number of seconds to run all queries: Maximum number of seconds to run all queries
XFS 21.936 21.619 22.190
EXT3 20.561 20.458 20.611

Изглежда ми като че ext3 да е с около 5 процента по бърза от XFS.

Debian GNU/Linux 6.0, mysql-server Version: 5.1.49-3, фаиловите системи монтири “както са”, тоест без каквито и да са настроики.

Уча Python. Бавно, малко по малко, защото нямам много свободно време. Но постоянно. Днес потърсих някаква група за Python, в която си говорят на Български език, и се оказа че няма. Затова реших да направя. Ето я:

Направих локален mirror на саита softpanorama.org. За всеки случаи, защото много често го ползвам саита за справка, а и защото уча за изпита Oracle Solaris 10 System Administrator Certified Professional Exam, Part II, и саита се оказа чудесен учебник точно за този изпит.

delicious

Ползвам http://www.delicious.com/ от 2005 година. Говори се че Yahoo ще спират работата по проекта, и delicious ще престане да съществува. Затова, е полезно редовно да се прави резервно копие на Bookmarks.

Ползвам  mysqlicious: http://code.google.com/p/mysqlicious/, и веднъж дневно архивирам в локална база данни. За целта освен mysqlicious скрипта инсталирах и php5-cli (command-line interpreter for the php5 scripting language). Направих базата данни, сетнах db user and password във mirror.php, и добавих в кронтаба

Windows Phone 7: The Best Choice For Patent Trolls

Позволявам си да публикувам на страницата ми писмото на Peter Brown до info-fsf mailing list. За мене е важно.

Windows Phone 7: The Best Choice For Patent Trolls

BOSTON, Massachusetts, USA — Friday, October 8th, 2010 — The Free
Software Foundation (FSF) today issued a warning to consumers over
Microsoft’s upcoming Windows 7 Phone Series. The software release is
backed by a reported 400 to 500 million dollar marketing campaign that
aims to distract consumers from its history of abusive behavior, and
recent actions as a patent troll: attacking free software based phones
like Android.

FSF is advising citizens to help increase awareness for the threat that
Microsoft posses to computer user freedom, providing details at:

http://www.fsf.org/blogs/community/windows-phone-7-the-best-choice-for-patent-trolls

“Software patents are the most important anticompetitive,
anti-software-developer tool available. And right now they are being used
by Microsoft in an attempt to crush computer users’ freedom. Proprietary
software like Windows 7 Phone are designed to keep users divided and
powerless and must be rejected” said Peter Brown, FSF executive director.

“Windows 7 Phone Series is another cookie-cutter example of Microsoft’s
bumbling maliciousness to everything it does.”, said Matt Lee, FSF
campaigns manager, “Microsoft’s damaging approach to software freedom,
coupled with their utter contempt for customers and developers alike, has
produced yet-another-platform of systematic control. This is a platform
designed only to appease its shareholders and help the folks at the MPAAs
and RIAAs of the world feel better about the chaos they seek to foster
surrounding digital restrictions and other technical folly imposed on
computer users.”

About the Free Software Foundation

The Free Software Foundation, founded in 1985, is dedicated to promoting
computer users’ right to use, study, copy, modify, and redistribute
computer programs. The FSF promotes the development and use of free (as in
freedom) software — particularly the GNU operating system and its
GNU/Linux variants — and free documentation for free software. The FSF
also helps to spread awareness of the ethical and political issues of
freedom in the use of software, and its Web sites, located at fsf.org and
gnu.org, are an important source of information about GNU/Linux. Donations
to support the FSF’s work can be made at http://donate.fsf.org. Its
headquarters are in Boston, MA, USA.

About Free Software and Open Source

The free software movement’s goal is freedom for computer users. Some,
especially corporations, advocate a different viewpoint, known as “open
source,” which cites only practical goals such as making software powerful
and reliable, focuses on development models, and avoids discussion of
ethics and freedom. These two viewpoints are different at the deepest
level. For more explanation, see
http://www.gnu.org/philosophy/open-source-misses-the-point.html.
