After being a Shaw TV and Internet customer for several years, I recently made the switch to Telus Optik TV and Telus Optik High Speed Turbo Internet. While I’m very happy with both the Optik TV and Internet so far, there have been a few bumps along the way. For example, the other day I hooked up a DD-WRT powered wireless router to the network and experienced an IGMP multicast packet flood when I turned on the TV. In this article I show you how to use ebtables to block an IGMP multicast packet flood on a DD-WRT WLAN when watching IPTV. …Continue reading » How to Block IGMP Multicast Flood on a WLAN When Watching Telus Optik TV (IPTV)

When I’m not at the office, I live in T-shirts. As such, I go through a lot of t-shirts and I have to replenish my supply regularly. But what’s a good geek supposed to do when he can’t find one he likes at his local mall? That’s right, he makes his own!
I recently used zazzle.com to make some cool Linux T-Shirts for my own use. When my friends saw me wearing them, they wanted to buy them too. So, I released my Linux T-shirts to the public. Check out my Linux T-shirts at my Zazzle store.
You’ll notice that many of my Linux T-shirts feature Tux the penguin, the mascot of Linux. Tux was designed by Larry Ewing, using The GIMP.
If you decide to take a whirl at making your own shirts, please be respectful of others’ intellectual property and either make your own graphics, use graphics that are in public domain or get the permission of the creator. For example, according to Larry Ewing’s website, he grants you permission to use the Tux logo as long as you acknowledge both him and the GIMP.
