Developer Linux News for Aug 14, 2008
Floating Point Math in Bash, Part 2 (Wait for System Load) (2008-08-14 19:34:27)
Linux Journal: "If you run scripts that require
a lot of execution time it's a good idea to try to avoid letting
them overload your system. You can run them via nice, but if for
example your script is sending a bunch of emails your email daemon
isn't running via nice and it may itself get out of control. One
way to deal with this is by using the values in /proc/loadavg to
pause when your system load gets too high."
2.6.27-rc3, "Things Really _Have_ Calmed Down" (2008-08-14 18:04:27)
Kernel Trap: ""Things really _have_ calmed
down, and hopefully we've also resolved a lot of the regressions in
-rc3," began Linus Torvalds, announcing the 2.6.27-rc3 Linux
kernel. He noted that much of the patch size was from the inclusion
of the new ath9k wireless driver, with much of the rest of the
patch size due to the renaming of many arch include files in the
ARM, AVR32 and m68lnommu architectures."
Lessons From PHP 4.4 End-of-Life Announcement (2008-08-14 16:34:27)
OStatic: "The developers of PHP announced last
week that PHP version 4.4.9 is now available. This would not be
remarkable in and of itself, except that the developers also
indicated that this would be the last release of PHP 4.4."
Ugandan Students Translate Firefox (2008-08-14 16:04:27)
Tectonic: "Students and linguists from Makerere
University have translated the open source web browser, Mozilla
Firefox, into Luganda at a Translate@thon held on the campus in
Kampala, Uganda last week. The two-day gathering brought together
almost 200 students and allowed them to make a practical
contribution to their language's presence in the digital age."
From Scripting to Object-oriented Python Programming (2008-08-14 11:04:27)
IBM Developerworks: "Often it is difficult to
make the transition from procedural scripting to object-oriented
programming. This article explores how to reuse knowledge from PHP,
Bash, or Python scripting to transition to object-oriented
programming in Python. The article also briefly touches on the
appropriate use of functional programming."
Coming Soon: AMD R600 3D Documentation (2008-08-14 09:34:27)
Phoronix: "Since the end of 2007 it has been a
mixed bag as to whether AMD would assist the open-source community
in developing the Mesa 3D driver (as part of their open-source
strategy) by releasing the register documentation covering the 3D
engine or by providing sample source-code -- as they had been
uncertain as to what would be more beneficial."
Converting troff to HTML (2008-08-14 08:04:27)
Linux Journal: "This is another from my "rusty
scripts" collection which was written for a specific task long ago.
In this case, we were converting some internal documentation from
troff using the mm macros into HTML."
Integration at Akademy (2008-08-14 06:34:27)
KDE Dot News: "One of the talks on Saturday
morning was about integration. As it was given by Inge Wallin it
quickly started to resemble a Marble talk - fans of that
application must be having a blast, as there's also a 'real' talk
about Marble by Patrick Spendrin. Marble was used by Inge to show
one of the longtime strengths of KDE - integration."
Beef up the Find Command in Firefox (2008-08-14 00:34:27)
IBM Developerworks: "This article presents
tools and code needed to add your own text-searching interface to
Firefox. With a Greasemonkey user script and some custom
algorithms, you'll be able to add grep -v functionality to text
searches — that is, highlighting a first search term where a
second one is not located nearby."
