To quickly setup a working Java SE project using Hibernate, download Hibernate Core 3.5.0-CR-1, which also includes EntityManager and Annotations.

Blocking blind SQL injections using mod_rewrite
If there are a lot of SQL statements in the Apache logs, there’s most probably someone running blind SQL injection attacks against one of the local websites. Above all one has to make shure, scripts are not vulnerable to such attacks, but often attackers exploit bugs that can’t be easily fixed.
To block most of this kind of hacking attempts, one can use the following mod_rewrite...

Tunneling Samba over SSH on Mac OS X
When using localhost for tunneling Samba on Mac OS X, the following error message will be displayed on trying to connect to smb://localhost:
The server “127.0.0.1” is available on your computer. Access the volumes and files locally.
A simple workaround is to add an alias to lo0:
sudo ifconfig lo0 alias 127.0.0.2 up
Then simply create the tunnel:
sudo ssh -L 127.0.0.2:139:DESTINATIONIP:139...

INSERT OR UPDATE for PostgreSQL
The easiest way I found to simulate a INSERT OR UPDATE using PostgreSQL (or pretty much any other RDB) is using the INSERT INTO … SELECT syntax:
INSERT INTO myTable (myKey) SELECT myKeyValue WHERE myKeyValue NOT IN (SELECT myKey FROM myTable); UPDATE myTable SET myUpdateCol = myUpdateColValue WHERE myKey = myKeyValue;
This way you don’t need any complex trigger or transaction...

Installing the GPLPV drivers on a Windows 2008 R2...
To speed up a Windows domU, the GPLPV drivers do a great job in paravirtualising essential parts of the system. The latest Windows versions require drivers to be signed in order to be installed. When trying to run gplpv_Vista2008x64_0.11.0.188.msi on a Windows 2008 R2 domU, the installer shows a message about activating “test signing” mode.
This is done via:

Ubuntu 10.4 (Lucid Lynx) and...
Apparently due to some usability tests, the newly available Ubuntu Lucid Lynx Beta has the window buttons on the left side. This is fine for many and if you are used to keyboard shortcuts you wouldn’t care about placement of buttons anyway, but in case you want to have the old style back, this is for you.
Open a Terminal and run the following:
gconf-editor
This opens a registry-like...
