Airline security

I’d just like to look at this recent airline bombing attempt to see how effective the security measures have been and will be:

no liquids > 100ml

well it was solid and hidden

do not fly list

with over one million names on it, the terrorist was not on it

the US was warned by the terrorists father that he [...]

Version updates using pub/sub

I have an android smartphone and whilst overall I’m very happy, the marketplace is definitely a very disappointing weak spot. Searching takes an _age_ (this is from _the_ search company) and often fails - although sometimes a reboot then picks up the application!
I have installed atrackdog to tell me which programs need updating, however [...]

Email client setup

I’ve recently changed my laptop and as it’s a small netboot, I’m running Ubuntu netbook remix on it. Today I’ve setup email on it and it’s a little involved so I thought it worth documenting.
First a little background - I run my own email servers and I like using “mutt” as my email client [...]

Of course these days we have [...]

KSM running

I’ll write up a bit more in a while on Bitcube, but for the record:

full_scans: 71
max_kernel_pages: 128571
pages_shared: 13640
pages_sharing: 19803
pages_to_scan: 100
pages_unshared: 79285
pages_volatile: 322
run: 1
sleep_millisecs: 20

KSM is “Kernel Samepage Merging” and is a way to share memory between virtualisation instances, thus saving huge amounts of memory. In this case it’s a redhat box and another [...]
