LUV President's Report to the Annual General Meeting, September 2011
Submitted by lev_lafayette on Tue, 09/06/2011 - 00:53The role of President from September 2010 to September 2011 period was initially one of accident; in my role as Public Officer I attended the Annual General Meeting and left the evening as President of the association. Thrown into this somewhat unexpected role I set as a priority ensuring that we had speakers for our LUV-main and LUV-beginners events, which was achieved quite quickly.

Installing the GNU Debugger
Submitted by lev_lafayette on Tue, 07/26/2011 - 22:48The GNU Debugger (GDB) is the standard debugger for the GNU software system. It is a portable debugger that runs on many Unix-like systems and works for many programming languages, including Ada, C, C++, FreeBASIC, FreePascal and Fortran.
Installation is trivial, but slightly interesting for illustrative purposes. First download and unpack:
cd /usr/local/src/GDB
wget ftp://ftp.gnu.org/gnu/gdb/gdb-7.3.tar.gz
tar xvf gdb-7.3.tar.gz
cd gdb-7.3

You are, of course, one the most well-known IT security experts in the world. Your company, Kaspersky Lab, is one of the largest and most successful providers of a suite products that protect users against various forms of malware.

Could Your Business Gain From A Switch To Open Source?
Submitted by lev_lafayette on Sat, 04/16/2011 - 08:32I'll start off with a caveat, I am an open-source advocate, a long standing committee member and current president of Linux Users of Victoria (http://luv.asn.au). My overall approach is that computer programs are scientific problems, and therefore there is an inherent tendency towards a better solution when the source code can be freely analysed, distributed and developed; release early, release often and with many eyes all bugs are shallow (to paraphrase Eric Raymond's famous essay 'The Cathedral and the Bazaar').
