  • hydrogen audio forums about audio software etc
  • rockbox open source firmware for music players. Very useful if the original firmware wont play certain formats, or has restrictions on copying music off the player.
  • mpd music player daemon. music playing software designed to be run over a network. If there is a network attached computer connected to an amplifier and running mpd, other computers on the network can control the player by using mpd client software (of which there are many to choose from, i use ncmpcpp). Can run on raspberry pi. Client and daemon can also both be running on the same computer. mpd and ncmcppp guide

to take 30 random mp3s and put them in a directory (i use this to randomly choose some of my music to put onto my mp3 player): 

find -name "*.mp3" | sort --random-sort | head -n 30 | xargs -n 1 -i^Cd '\n' cp {} ~/sometunes


other

Many of these links need to be (or already have been) put elsewhere on the wiki

geeky linux tools

email software
backup/archiving tools for linux
diff -qr source destination
comm -3 <(ls ~/dir-new/) <(ls ~/dir)        # compare two directories

Find duplicate files: 

find -not -empty -type f -printf "%s\n" | sort -rn | uniq -d | xargs -I{} -n1 find -type f -size {}c -print0 | xargs -0 md5sum | sort | uniq -w32 --all-repeated=separate

Find and delete duplicate files: 

find -not -empty -type f -printf "%s\n" | sort -rn | uniq -d |  xargs -I{} -n1 find -type f -size {}c -print0 | xargs -0 md5sum | sort | uniq -w32 --all-repeated=separate | cut -f3-100 -d ' ' | tr '\n.' '\t.' | sed 's/\t\t/\n/g' | cut -f2-100 | tr '\t' '\n' | perl -i -pe 's/([ (){}-])/\\$1/g' | perl -i -pe 's/'\/\\'\/g' | xargs -pr rm -v

booklet printing on linux

some tools, for example, for reordering pages of an a4 documents to make an a5 booklet or zine. 

pdf2ps                                              # convert a pdf document to postscript      
psbook in.ps out.ps                                 # reorder the pages to make a book,  
psnup -s1 -2 book.ps booklet.ps                     # shrink to 2 pages on each A4 side
ps2pdf in.ps out.pdf                                # convert it back to a pdf

If you dont have a duplex printer probably you want to print the even pages, put them in the paper drawer (the right way around! very confusing!) then print the odd pages 

lpr -P myprinter -o page-set=even -#1 infile.pdf    # print the even pages  
lpr -P myprinter -o page-set=odd -#1 infile.pdf     # print the odd pages

encryption

Most simple usage - gpg encryption of a single file: 

 gpg -c file

This prompts for a password and gives file.gpg. To decypt: 

 gpg -d file.gpg > file

non-commercial email providers

please add more

local announcements websites

For buying/selling secondhand, etc. Better than ebay because you meet the person face-to-face and put money in the hand (no third parties pinching fees). This requires some trust, which builds community.
