This is your host, Mark Walker—now let’s get to the content.
This episode, number 33, was produced on September 30th, 2012—and today’s topics will include:
Selections from “yum info recent” from several yum repositories
…
and the Latest from FredLUG, the Fredericksburg Linux Users Group.
Today’s feature is “Basics of Networks,” from the The ABCs of Linux series of FredLUG presentations.
And we’ll close with a Creative Commons licensed work by
It-Alien, entitled Kiss me on 7.
Here are some recently updated items in the yum repositories:
→Name : btparser
Summary : Parser and analyzer for backtraces produced
by GDB
Description : Btparser is a backtrace parser and analyzer,
which works with backtraces produced by the
GNU Project Debugger. It can parse a
text file with a backtrace to a tree of C structures,
allowing to analyze the threads and frames of the
backtrace and work with them.
:
Btparser also contains some backtrace manipulation and extraction
routines:
- it can find a frame in the crash-time backtrace where the
program most likely crashed (a chance is that the function
described in that frame is buggy)
- it can produce a duplication hash of the backtrace, which helps
to discover that two crash-time backtraces are duplicates,
triggered by the same flaw of the code
- it can "rate" the backtrace quality, which depends on the number
of frames with and without the function name known (missing
function name is caused by missing debugging symbols)
→Name : clamav
Summary : End-user tools for the Clam Antivirus scanner
Description : Clam AntiVirus is an anti-virus toolkit for UNIX. The main purpose
of this software is the integration with mail servers (attachment
scanning). The package provides a flexible and scalable
multi-threaded daemon, a command line scanner, and a tool for
automatic updating via Internet. The programs are based on a
shared library distributed with the Clam AntiVirus package, which
you can use with your own software. The virus database is based on
the virus database from OpenAntiVirus, but contains additional
signatures (including signatures for popular polymorphic viruses,
too) and is KEPT UP TO DATE.with your own software. The virus database is based on

→Name : konsole-part
Description : Konsole kpart plugin.
KParts is the component framework for the
KDEdesktop environment. An individual component is called
a KPart. KParts are analogous to Bonobo components
in GNOME and ActiveX controls in Microsoft's
Component Object Model. Konsole is available as a
KPart and is used in applications like Konqueror and Kate.
→Name : llvm
Summary : The Low Level Virtual Machine
Description : LLVM is a compiler infrastructure designed for compile-time,
link-time, runtime, and idle-time optimization of programs from
arbitrary programming languages. The compiler infrastructure
includes mirror sets of programming tools as well as libraries
with equivalent functionality.
You can find additional information on these, and many other recently updated packages, by typing yum info recent at the command line.
FredLUG participated in Software Freedom day again this year, on September 15th, 2012. Again this year we were in front of the main library in downtown Fredericksburg. We gave away several copies of Fedora 17 live disks with install option—and also an updated version of the OpenDisc, which is a collection of open-source programs for Windows. Like other groups on the SFD email list reporting low turnout this year, that was our experience also. We’ll possibly try multiple locations in the area next year.
At the FredLUG meeting on September 29th, 2012, Peter Larsen gave a presentation on the basics of networking—you’ll hear a portion of that in a moment in the feature section of this podcast episode. (Peter’s whole talk, and a practical how-to in subnetting by Ted Brunell, is available from the home page at issuesdigest.com (direct link is in the show notes http://www.issuesdigest.com/fredlug).
The Fredericksburg Linux Users Group, FredLUG, meets on the third Monday of each month at the main Library on Caroline Street downtown—meeting time is 7 PM 1900 US Eastern time.
FredLUG also meets on the “last-Saturday-of-the-month” at the England Run library branch, which is west of Falmouth in Stafford County. A Google-maps link is in the show notes below.
