Command Line History

Posted by Scoundrel under Development , General

Inspired by the Rail Spikes:

bash-3.2$ history 1000 | awk '{a[$2]++}END{for(i in a){print a[i] " " i}}' | sort -rn | head
228 cd
167 git
10 ssh
10 DEPLOY=production
6 sudo
6 pwd
6 ./script/import_views.rb
5 rm
4 rake
4 mv
bash-3.2$

Really interesting stats, I’d never guess that git is used more than ssh on my desktop (I’m a remote worker and mysql consultant so I ssh really often). :-)

32bit VS 64bit - what do you use?

Posted by Scoundrel under Admin-tips , Development , General

Hello my dear readers.

Today I have a question for all of you. What platforms (32bit or 64 bit) do you use for your servers with more than 4Gb RAM? I’m asking because recently we‘ve hit few really weird bugs in Linux kernels 2.6.18 to 2.6.22 and all those bugs were PAE-related. Now I’d really love to move all machines to 64-bit, but I’m in doubt because we don’t know too much about Rails stack (ruby, mongrel, haproxy) on 64-bit platforms (all our DB boxes are 64-bit of course).

So, please drop me a line if you have any experience (negative or positive) with Rails platform on 64-bit machines. I’d really appreciate your help.
