IPv6 Subnetting – You and your customer

There’s this great debate in the IPv6 world about how to chop up your allocation into assignments for your customers.

Nvidia Fail

If you have a system built with the still quite good Nvidia GeForce 8800GTS graphics card, and decide to upgrade by adding a second one and running SLI, beware the Nvidia Fail. Nvidia in their wisdom made an upgraded version of the card called the 8800GTS 512. It is not SLI compatible with the original [...]

BT Fail :: Part 2

A new level of fail from our friends at BT Wholesale.

This has caused uproar in the ISP community as at first glance it appears as though the ISP [...]

Ghetto Antenna

Possibly the most ghetto thing I’ve ever built: The Ghetto Wireless Antenna. Don’t worry, it’s only temporary. It’s a twist tie with an end stripped off, folded over and shoved into the N-type antenna connector. Suprisingly it gives quite good reception, increasing the signal strength to nearby laptops by about 20db.
