DNS and Organisational Planning

I fixed up my DNS server last week. Its really strange how organisations can still rely on hosts file for name resolution. What was even more amazing was that I just accepted that for almost 2 years. When the network change and you realise that its a real pain to make changes and you start wondering who's bright idea it was to use the hosts file in the first place and of course its always easier to for people to blame the guy who's not there.

So whats the big deal with running a DNS server anyway? Its not a big overhead to create a functional a workgroup DNS server, unless of course, its some windows thing that need to log into some domain that requires some auto population something that caches some hosts to some server that needs to be assessible via some funny port across the intranet, etc? No doubt windows can also do a simplified version, but in a typical organisation setup, policies determine logic. Mind you that common sense normally means that logic should dictate policy. But in the burocratic enviornment who cares if things just dont make any sense?

If you are wondering why fully "featured" management applications are so expensive, it is probably because they are banking on the fact that there is no planning made by system mangers who are more than willing to spend the extra cash to hide their ignorance, thinking the package can do their work for them. I'm sure you heard the saying "a computer is only as good as the user". In my experience, most system managers purely have no understanding on how the system works and I dont mean by the book definition on what the system is.

So is planning that difficult? A tour guide out in the bush told me things dont need to be complicated to do stuff. I think that might explain some of the many interesting inventions here that are so cool, but taken out of context, just look like really strange objects. The umbrella clothes rack which is a real big hit here and the shoo roo, a car mounted whistle to shoo kangaroos from hitting your car. One of the greater signature inventions out in the bush is the "stick to check rock movement", which is actually a stick to check rock movement.

Apparently some scientists have debated how to check if lava tubes were unstable and prone to collapsing. Some suggested using all types of sensors, but I was told it was an aussie who stuck a stick against the wall and said that will work.

dead pi

Well, I guess it has to happen at some point. the home automation raspberry pi has died. Much to do with the stupid Strontium mini SD card. ...
