Security considerations of a day - printers work for the CIA

• network printers can copy printed documents to their private HDD cache store. Remember that if you want to print naked photos of your girlfriend :)
• forensics can identify the printer and computer equipment that has been used to print the document. Beware the yellow dots. 
• some advanced network printers by default leave SNMP, FTP (sic!) and other interesting ports opened. And some network administrators leave default username and password for network printers.

The best Gnome borders and control elements

To make my Linux desktop shine like a deer's ass in the woods I use Gnome and Gnome-Art. At this moment I find the following combination of the window and control elements the most exciting:

• window border - Gorilla
• control elements - WarmGorilla-GTK2
• icons - Gartoon

Any competitor?

My activity on Java Black Belt JMS exam

I've fixed some questions in JMS exam on Java Black Belt. I'm in the top 5 of the exam contributors now.

Assume that you've got the JMS topic named foo.bar.baz.qux .

• pattern * matches single level of topic hierarchy (i.e. foo.*.baz.qux or foo.bar.*.*)
• pattern > matches all levels recursively (i.e. foo.> or >.qux)
