  • Grab your bibtex file from CiteULike.

    I love CiteULike. It makes keeping a bibtex library easy and keeps all my papers in one place. However, it can be a pain when I add new entries and have to go through the procedure for downloading the new version in my browser, so I made this to grab it for me! I actually pipe it directly into a couple of SED one liners to tidy it up a bit too. Extremely useful, especially if you make a custom BibTeX script that does this first. That way you can sort a fresh BibTeX file for each new paper with no faf. To use just replace with your CiteULike user name. It doesn't download entries that you've hidden but I don't use that feature anyway.


    -1
    curl -o <bibliography> "http://www.citeulike.org/bibtex/user/<user>"

  • Remove embedded fonts from a pdf.

    It's sometimes useful to strip the embedded fonts from a pdf, for importing into something like Inkscape. Be warned, this will increase the size of a pdf substantially. I tried this with only gs writing with -sDEVICE=pdfwrite but it doesn't seem to work, so I just pipe postscript output to ps2pdf for the same effect.


    1
    gs -sDEVICE=pswrite -sOutputFile=- -q -dNOPAUSE With-Fonts.pdf -c quit | ps2pdf - > No-Fonts.pdf

shell function which allows you to tag files by creating symbolic links directories in a 'tags' folder.
shell function which allows you to tag files by creating symbolic links directories in a 'tags' folder. The tag function takes a tag name as its first argument, then a list of files which take that tag. The directory $HOME/tags/tagname will then hold symbolic links to each of the tagged files. This function was modified from bartonski's (http://www.commandlinefu.com/commands/view/10216) inspired by tmsu (found at https://bitbucket.org/oniony/tmsu/wiki/Home) with readlink function by flxndn (http://www.commandlinefu.com/commands/view/10222). Example: $ tag dog airedale.txt .shizturc weimeraner.pl This will create $HOME/tags/dog which contains symbolic links to airedale.txt .shizturc and weimeraner.pl

Get AWS temporary credentials ready to export based on a MFA virtual appliance
You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token. This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use: `awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'` You must adapt the command line to include: * $MFA_IDis ARN of the virtual MFA or serial number of the physical one * TTL for the credentials

On Screen micro display for battery and CPU temperature. nifty, small, omnipresent
My firefox overheats my cpu, sometimes above 90 degrees Celsius ( hence the name? ) To keep an eye on temperature, I put this command inside KAlarm ( a kind of cron) to be repeated every minute, for 5 seconds, color red ( default for osd_cat). Its pretty, ultra small, displays a micro 2 lines text on every desktop and over everything and do not steal focus or interrupt any task. I get the information passively, in the low profile bottom of the screen. Of course you can use it inside a terminal. Just do it: watch -n 60 'acpi -t | osd_cat -p bottom'
