At the time of writing, I run Debian on my primary computer and server, Ubuntu for my laptop and Mandriva for an older computer at home.
See the report on installing Debian and Ubuntu on an LG T1 express laptop.
Or an article on apt-file I wrote.
Here is a dump of a quick investigation on analog output hardware that works in linux.
The purpose of this page is to collect useful things that I tend to forget all the time.
coding video from motion jpeg, taken by standard still
photography camera.
ffmpeg -i mvi_1439.avi -ar 22050 -ab 32
slask.avi
coding video from jpeg pictures
mencoder mf://*.jpg -mf
w=640:h=480:fps=25:type=jpg -ovc lavc -lavcopts
vcodec=mpeg4:mbd=2:trell -oac copy -o output.avi
compressing an avifile
mencoder "$avifile" -o
"$outputfile" -ovc lavc -oac lavc
reading microsoft access databases (*.mdb) in
linux:
http://mdbtools.sourceforge.net/
Commandline:
mdb-tables
file.mdb lists the tables in the file
mdb-export file.mdb
tablename exports to a csv-file.
shrink photos
convert file.jpg -resize '640x480>'
smallfile.jpg
send mail from commandline
mutt -F ./.muttrc -s ”this is
the subject” -a attachment.file email@email.com <
file_with_bodytext.txt
let .muttrc contain:
my_hdr From:
my_email@email.com
set realname="My Name"
to get
proper from-adress and name.
Another possibility, if you do not
have a mail server locally, is to use an external smtp server and a
python script. mail.py
picking out a column (here: column 9) from a textfile,
columns separated by _:
cut -f9 -d_<file.txt
keeping the time accurate with ntp:
Set up ntp
(apt-get.... does the thing). Edit ntp.conf and add servers (see
http://unix.se/NTP)
Because my
adsl connection is not always up at boot time, the ntp might need to
started ”manually”. Sometimes it needs to be restarted. I have
the following entries in crontab, where /root/scripts/restartntp.sh
can be found here:
|
*/10 * * * * /root/scripts/restartntp.sh alive 2>&1
>>/root/logs/restartntp.sh |
To monitor that the clock is synchronized with ntp, I use
watch ntpq -pn
Look for the row with a * in front.
subversion setup: see the text on http://stacktrace.se/softdev/?permalink=subversion.txt (in Swedish)
change encoding on filenames (VERY useful when you switch
back and forth between operating systems etc)
convertfilenames.plsee
