TVtime is a high quality television
application for use with video capture cards.
The focus of tvtime is visual quality. It features on-the-fly picture
de-interlacing using a number of different algorithms, 16:9 display, 2-3
pulldown detection for NTSC sources, and a very nice on-screen-display
TVtime is a “must-have” companion for your TV capture card.
Worker is a dual-pane
graphical file manager for X, similar to the curses-based Midnight
Unlike most other file managers for Linux, worker requires a minimum
set of libraries (no QT or GTK), making it a lightweight and responsive
Worker can perform all the usual operations of a file manager (copy, move,
rename, delete) and also some typical Unix functions, such as chmod, chown,
create symlinks and hardlinks, etc… It is also possible to configure worker
to use “helper programs” to deal with specific kinds of files, in such a way
that hitting the ENTER key (or clicking) on a filename will automatically
invoke the correct viewer for that filetype. Many other file-manipulation
commands exist, and they can be assigned to hotkeys or buttons.
Another nice feature that will please those with large collections of
pictures is the “image mode”, where one pane shows a fast preview of the
currently selected image file on the adjacent pane.
One of the most unpleasant situations for a sysadmin is to have
a server breached. When that happens, invaders usually install a
rootkit which will ensure the
continuity of their access to the computer.
Chkrootkit is a utility that checks
for signs of rootkits in the server where it runs. It can identify over 60
different kinds of rootkits and variants, and can be run from cron daily (or
hourly), giving an early warning in case of problems.
Note: Systems security is not a simple matter. Utilities like chkrootkit
can help tremendously, but are not a substitute for a comprehensive security
policy and careful maintenance of your servers.
Tcptrace performs many different
kinds of analyses on network capture files. In its most basic form, tcptrace
produces a listing of all TCP connections found in the capture file. The
“long” option produces an interesting summary of each connection, including
packet totals and statistics, TCP flow information, throughput and error
statistics, and much more.
Tcptrace can also produce graphs showing the throughput, RTT sample, time
sequence, outstanding data on network, and segment size. To view the graphs,
you’ll also need xplot, (which, unfortunately, is
not the same xplot available in the
