Python+Expect named.conf additions/removals

So i was getting tired of manually ssh'ing to the trio of name servers my company runs whenever we needed to add a new domain. I set out to script the process and ended up with this:

Both expect scripts take a single argument, the domain to be added, be sure to modify the host part of the spawn ssh lines to fit your needs.

The expect script run on the master for domain additions
The Python script run by the expect script on the master:
The Python script run by the expect script on the slaves:

The expect script run on the master for domain deletions
The Python script run by the expect script on all servers:

The expect scripts assume you use public key authentication with ssh.
These are some of my first attempts at python scripting and i'm not a seasoned expect/tcl guy either so if these can't be of any help to anyone maybe i'll receive some constructive criticism instead that can help me!

Lægra ping innlendrar umferðar á OpenVPN.is tengingu!

Hér á eftir fylgir scripta sem tryggir að öll innlennd netumferð fari beint út gegnum ISP'ann ykkar í stað þess að taka krókaleið gegnum tunnel netsamskipta/openvpn.is UnZippa í My Documents: https://dl.dropbox.com/u/66544/is-net-routes.zip Keyra í run (windows takkinn+R): schtasks /create /ru %username% /tn is-net-routes /xml %userprofile%\Documents\is-net-routes\is-net-routes.xml Þetta virkar á windows 7 x64 professional. Ef schtasks skipunin virkar ekki á ykkar vél þá dugar að búa sjálfir til scheduled task sem keyrir við logon notanda og framkvæmir þessar aðgerðir í röð: powershell.exe -command {$client = new-object System.Net.WebClient;$client.DownloadFile('http://www.rix.is/is-net.txt',$env:temp+'\is-net.txt')} %userprofile%\Documents\is-net-routes\is-net-routes.bat Ef allt gengur vel mæli ég með að breyta nafnaþjónunum sem uppsettir eru á tunnel adapter OpenVPN.is yfir í nafnaþjóna ykkar ISP Hægt er t.d. að sjá með tracert mbl.is eftir uppse

Umbraco Dictionary Key Performance

I've re cently had the task of optimizing a clients website. On my tour of the site i noticed an instance where 20-30 dictionary keys are requested in succession for a single view. I decided to do some performance testing and find out how quickly the action is performed before and after caching. I made 25 keys in the backoffice with naming following this scheme "key0", "key1" and so on. controller action: public   string  Get() {      StringBuilder  sb  =   new   StringBuilder ();      var  timer  =   new   Stopwatch ();     timer . Start();      for  ( var  x  =   0 ; x  <   25 ; x ++ )         Umbraco . GetDictionaryValue( "key"   +  x);     timer . Stop();      return  timer . ElapsedMilliseconds  +   "ms "   +              timer . ElapsedTicks  +   " ticks" ; } Results were on first run (presumably includes a database query) 112ms 262011 ticks  then progressively lower  32ms 74887 ticks
