Seek for Thunderbird ups your email functionality according to LifeHacker –

Thunderbird extension Seek adds advanced search and sort functionality to the open source email client, Thunderbird, through a feature called faceted browsing […] narrows down emails by a number of conditions, introducing tons of useful ways to slice and dice your inbox to find exactly what you want. Add to that the timeline feature, which looks like a blast along with being useful, and we’ve got a pretty worthwhile Thunderbird extension here…

My personal favourite tool –

ldd, want to know which Linux thread library java is linked to?
# ldd /usr/java/jre1.5.0_11/bin/java libpthread.so.0 => /lib/tls/libpthread.so.0 (0x00bd4000) libdl.so.2 => /lib/libdl.so.2 (0x00b87000) libc.so.6 => /lib/tls/libc.so.6 (0x00a5a000) /lib/ld-linux.so.2 (0x00a3c000)

SysV not working in a jail ?

admin — Tue, 11 Mar 2008 09:44:23 +0000

If your SysV (used by cache programs, and others) isn’t working inside your FreeBSD jail simply set “security.jail.sysvipc_allowed=1″ in /etc/sysctl.conf. Note that there are possible security implications with this.

pkg_add From Local Servers

admin — Tue, 11 Mar 2008 02:46:39 +0000

pkg_add is a FreeBSD tool for installing packages, much like Linux’s apt-get and other tools. When you run it you can use the -r option to fetch a package, for example:

pkg_add -v -r zip

When you do this, you’ll see it going off to download from one of the main FreeBSD servers, which can often be far away from you and a lot slower. If you’d like to download locally set the PACKAGEROOT environment variable to the server you’d like to use. For example:

export PACKAGEROOT=ftp://ftp.za.freebsd.org

“za” is the country code for South Africa. Most countries have local mirrors, and there are lists online. For example, “uk” or “au” would be for the UK or Australia.
