  • What is Linux? and software confusion …

    A recent posting on the Blog of Helios prompted me to write a short and simple definition of Linux that might be useful for current non-users of this operating system. It is however a difficult definition in the context of what people already know. And the fact of the matter is that what the general…

  • Net Neutrality – South Africa

    Net Neutrality is currently, and has been for some time, a raging hot topic in the US. The FCC recently took Comcast to court for throttling customers’ bandwidth – and lost.

    Microsoft had a large Patch Tuesday in February – with an unintended side effect: large amounts of blue screens. This turned out to be due to an interaction between the Alureon rootkit and the patch for KB977165 which updates the Windows kernel. This month’s patches also contain kernel updates, and so have the same incompatibility…

  • Google hacks affect local SA users

    So it seems that some South African users have been bitten by the GMail hack bug. Big Whoopy Ding! They’re not honestly using a free on-line email service for anything critical, are they?
