An interesting article appeared e-week.com about IT certification. We first saw the high quality CNE from Novell that your average bricklayer could pass (I know, because the owner of one of the companies I worked for didi it...) Possibly, after almost 20 years, companies have figured it out!!! http://www.eweek.com/article2/0,1895,1954198,00.asp?kc=ewnws042706dtx1k0000599 |

I have recently purchased some new reference books in the general field of Information Security from Amazon.com. One of the books I finished last night was 'Buffer Overflow Attacks - Foster, Osipov, Bhalla, and Heinen - ISBN 1-932266-67-04' It was well written, and easy to read. It starts off describing how Shellcode operates, including the various methods available to inject it, then it moves on to stack exploits and heap exploits. There are tons of usefull examples (Some of which I recognise from my early programming days!! - Who says gets() is bad...) which made the content even easier to understand. I was especially interested in the discussion of how to exploit heap overflows. Finally, it shows a few techniques for detecting potential exploits in source code. In all, well worth the money I paid. |

I'm going bald next Friday - Participation in 'the worlds greatest shave' for lukemia is assisting in the process.
Photos should make it into the scouting newsletter. It will be quite cold for a while. And just in case you are asking, no, Megs isn't letting me shave my beard off. |

Have to build a 3 lane timer and winner determining system. Sounds like another PIC project.
Wo Hoo Update - It will be a 16F84, with a 4 line backlit LCD Display. The lane sensors will be optical using phototransistors, and it will measure overall time taken to traverse the track. Nice, simple, and inexpensive to design. - I wonder if Silicon Chip would publish it. - On that subject, they published a LED dice project for me in 2001, but that simple project never made it into kit form - I suspect that they didn't like the construction technique. To-do:- talk to Leo Simpson - the editor- to discuss their requirements and write to that. |

Did the planning for the term last night, quite a well rounded program. We should even be going to the planetarium.
Week 3 and 4 are building Kub Kars. UPDATE - I started the track for the Kub Kar program yesterday (Sunday) - *Lots* of routing involved. Have completed 2 of the 4 sections. I'll post some photos online when I take them. |

The Cub group are going to run an activity this term,
where everybody builds a small car out of wood. They are called Kub Kars.
There are races involved, and we should be seeing a high level of parental involvement, which is a good thing (tm). Our kits come from scouts Canada. Google for them. The big derby is 27 May, so it should be a hoot. |
