Simeon (hi, it’s me…) will be presenting a talk about fiber optics in computer networks, covering the basics like fiber types and transmission technologies, then discussing advancements (40/100Gbps, etc), and wrapping up with some commentary on fiber network roll outs in South Africa.

See you there!

Although this talk was entitled Attacks and Defenses, it focused mostly on hacks, and pretty cool ones at that. Marco walked us through some recent attacks against Win32 and FreeBSD on a kernel level, as well as some application layer stuff (x509, web apps, cloud attacks). Delivered with insight and humor this was an excellent talk. Thanks Marco and everyone who attended (thanks also for support from SensePost staff).

Update:

PLEASE NOTE THE VENUE HAS CHANGED A SECOND TIME

For directions (including an aerial photograph) please see the meetings page.

• If you would like me to add an event that I’ve missed, you can send me an email.
• If you use Google Calendar yourself, I can give you access to add events. Again, just ask.
• The calendar is also available in ICAL (.ics) format, if you would like to import it into your desktop or phone calendar.

Other changes:

• Moved the Forums, Wiki and Mailing lists links out of the sidebar, and turned them into tabs at the top of the page.
• Created a fresh blogroll category, for people who participate in TLUG meetings. Email me if you want your blog added.
• Added various links to LUGs, Programming Groups, Tuks academic departments and other interesting organizations.

Any feedback would be appreciated.

General feedback from all those who attended was very positive. Thanks to Beau, Jaco and all our guests!

Our topic for tonight has changed, Beau will be talking about botnets. See you all there!

Regards,
Simeon.

Topic: Botnets
Speaker: Beau Grobler
Date: 2 November 2009
Time: 18:30 for 19:00
Venue: University of Pretoria, lecture hall 1-18 in the Economics and Management Science building (building 54 on this map: http://web.up.ac.za/interactivemaps/mapeng/maincampus.htm).

We also have this blog, some mailing lists, some web forums, a wiki, an IRC server (irc.tlug.org.za) and a Jabber Server (tlug.org.za), all of which is used to varying degrees for collaboration and discussion.

There is no formal TLUG membership (if you’re on the mailing list, consider yourself a member), and we are open to everyone who would like to to participate (including the general public). Organization and administration is handled by a handful of people, most of which are UP alumni and have jobs and lives outside the University. We do this in our spare time.

TLUG is not an official UP student society, thus we do not get any money from the University, nor do we charge for membership (or anything else). Our online services run on hardware donated by ULS and hosted at the UP BI department. The UP CS department provides the venue for our meetings.

Since we rely on the generosity of our friends and former bosses/colleagues at UP for facilities, and on donations and volunteers for everything else, we can’t pay people to present talks at our meetings.

I hope this clears things up :-)
