Ubuntu 12.04 Eclipse SWT lib

by GarciaPL on Wednesday, 24 October 2012


I have recently installed Eclipse using Ubuntu Software Center in Ubuntu 12.04 and when I run it I have below message in log :

java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons:

So, fix of this problem is one of those lines which you should run in terminal :

For Ubuntu 12.04 32 bit :

ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86/

For Ubuntu 12.04 64-bit:

ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86_64/

Chrome deletes downloaded files

by GarciaPL on Saturday, 20 October 2012


Recently I have problem with Google Chrome from version 22.0.1229.94 in one moment, when I am downloading some file. After complete the download, Chrome immediately delete the file.

There are two possibilities to solve the problem :
1. Roll back Chrome to previous version
2. Remove from Windows (of course if you are using it) one of those updates (I do not know which one ;)) :

Cumulative Security Update for Internet Explorer 8 for Windows 7 for x64-based systems
KB 2744842

Nagios HP BladeSystem Ambient Temperature

by GarciaPL


I uploaded to my github (link in reference) a script which allow you to check average ambient temperature for all Bays stored in HP BladeSystem using it's Onboard Administrator from which I put below sample output.
