email software
backup/archiving

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

tools for those who have little or no connection to internet

  • kiwix wikipedia offline reader - read wikipedia when not connected to internet. The english wikipedia (text only, no images, user pages or discussion pages) compresses to about 8gb! You will need to download this data in 'zim' format, available as a torrent. list of wikipedias

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


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, no stupid rules, no sending stuff from the other side of the planet. This requires some trust, which builds community.
