rsync to copy only new files

copy only new files (keep old files on server) to server.

rsync -avz -e 'ssh -i id_rsa' from/* server:~/to/

for just printing, not executing, of what it will do

-avzn

notes

• works with local folders as well
• auto create folder for you, no need mkdir

bash script: copy to server, files that are modified today

(all in one line)

find * -mtime 0 -printf "%p " | 
awk '{print "scp -i sshid "$0" user@hostname:/path"}' | sh

copy files modified after 13 days ago

find * -mtime -13 -printf "%p " | awk '{print "cp -p "$0" ~/folder "}' | sh

create a file.avs:
make sure you write the full path!!

DirectShowSource("c:\locationto\video.mov")

You can now open a .mov file in virtual dub. (ぱちぱち)
For compression, I currently use xvid, which converts a 22 minutes-ish .mov 1.9Gb video file to a 361mb .avi (resolution is 640x480).

Any Video Converter is a good encoder, though it has a suspicious name... but i need more compression, virtualdub may do it... i guess.

valgrind

there are times when the code works in mac while it breaks in ubuntu.

this was found by

valgrind --leak-check=full --memcheck:leak-check=full --show-reachable=yes -v ./programName
