Monitor DB2 rollback progress

If you have a large transaction that is in rollback status and you want to know how much of the work is rollbacked then you can use this:
- get AGENT ID for the connection that is in rollback status (db2 list applications show detail)
- run db2 get snapshot for application agentid YOUR_AGENT_ID | grep Work

Running NetBeans from Unity launcher gives you two icons for NetBeans

When you add NetBeans desktop file to Unity launcher and run it, you could get two icons for NetBeans.
Steps to solve this:
- remove NetBeans from launcher
- add StartupWMClass=NetBeans IDE 7.4 to desktop file
- add NetBeand back to launcher

This is how my netbeans.desktop files looks like:
[Desktop Entry]
Encoding=UTF-8
Name=NetBeans IDE 7.4
Comment=The Smarter Way to Code
Exec=/bin/sh "PATH_TO_NETBEANS_EXEC"
Icon=PATH_TO_NETBEANS_ICON
Categories=Application;Development;Java;IDE
Version=1.0
Type=Application
Terminal=0
Name[sl]=NetBeans IDE 7.4
StartupWMClass=NetBeans IDE 7.4
OnlyShowIn=Unity;
X-UnityGenerated=true

Improving security in Firefox

Today I found a nice website that tells you how secure your TLS/SSL client is. 

I'm using Firefox 26.0 and the website said that my TLS client is "Bad".

Btw., Google Chrome  31.0.1650.63 is rated as "Probably OK" from the start.

Hmm, Firefox can't be so much worse than Chrome, right?

So, couple of minutes later that I found another website that helped me bring Firefox to the same level with couple of steps:

- go to about:config

- set security.tls.version.min to 1 (TLS 1.0)

- set security.tls.version.min to 3 (TLS 1.2)

- set security.ssl3.rsa_fips_des_ede3_sha to false to disable SSL_RSA_FIPS_WITH_3DES_EDE_CBC_SHA chiper, which is known to be insecure
