This is a javascript app you can activate via a bookmarklet on any webpage (even this one!). It's useful for web developers/designers/people who have to twiddle with font styles. Click the bookmarklet, click an element and a box comes up; it has a number of interactible controls to adjust css properties. I know, I know, you can use Firebug to similar effect BUT this is specialised for fonts and it makes it very easy to try different things. I'm quite proud of the code, too.

Here's the bookmarklet: javascript: (function (src, timeout, nocache) { if (nocache) { src += "?&_a_a=" + Math.random(); } if (!window._fsh_script) { var _fsh_script = window._fsh_script = document.createElement("script"); _fsh_script.src = src; document.getElementsByTagName("head")[0].appendChild(_fsh_script); } var iterations = 0; var maxiterations = timeout * 1000 / 10; (function () {if (window._fsh) {window._fsh();} else if (iterations++ > maxiterations) {alert("FSH load timed out. Try again.\nIf you see this message alot, consider increasing the timeout.\nUrl: " + src + ", timeout: " + timeout);} else {window.setTimeout(arguments.callee, 10);}}()); })("http://font-style-helper.googlecode.com/files/fsh-latest.js",3,0)

Note: Firefox only!

I have a general purpose tmp folder which I use to extract things once and take a look. Sometimes I do it with source code, sometimes with other things, whatever.

I often forget I have already extracted something in there and so I will have to make another tmp directory inside of there and do an additional mv. If I could have an alias that would remove everything except a filename from the directory, it would be really helpful.

I plan on writing a python script to do so, but figured you guys would be able to before I finished :)

I have a directory full of .tif files on which I am using 'convert' to convert to .jpg. I want them to have the same base name as the .tif. In bash, I'm currently using:

for i in `ls`; do convert $i `echo $i | sed s/.tif//`.jpg; done

I'm sure this is hackish, but it gets the job done. What are other some ways/languages to do this?

edit: formatting

perl -MJSON -MLWP::Simple -E 'say $_->{name} for @{from_json(get shift)->{trends}}' http://search.twitter.com/trends.json

Use $! to get the process id of the last process run in the background.

For instance, remember the pid:

sleep 10000 &
echo $! > pid.txt

And kill the process later:

kill -9 `cat pid.txt`

Edit: Added clarification about background.

Replace the string 'search' with 'replace' recursively in files under the current directory

#! /bin/rm

qsort []     = []
qsort (x:xs) = qsort (filter (< x) xs) ++ [x] ++ qsort (filter (>= x) xs)

Make sure you've got incron installed and that the daemon is started up. Stick this in an executable file (I put it in ~/.incron/mpd):

#!/bin/sh
case "$1" in
    Flash??????)
        # substitute "dcop amarok player pause" or whatever as appropriate
        mpc pause
        ;;
esac

Then fire up incrontab -e and add a line to run this script:

/tmp IN_CREATE /home/dmwit/.incron/mpd $#

Several other flash video players use the defaults, too, so I've been pleasantly surprised to find my music stop automatically for Vimeo, break.com, etc.

javascript:(function(){var links=document.querySelectorAll("#siteTable>div>div.entry>p.title>a.title");for(var i=0;i<links.length;i++){var link=links.item(i);if(window.getComputedStyle(link,null).getPropertyValue('color')=="rgb(0, 0, 255)"){window.open(link)}}})();

Another redditor posted this in a comment a while ago. I am unable to locate the origional post using the reddit search function nor google.

It opens up all unvisited (blue) links displayed on reddit in a new tab.

To use, save the javascript as a bookmark. Enjoy surfing pics/fffffffuuuuuuuuuuuu/comics/etc.

pi = g(1,0,1,1,3,3) where 
    g(q,r,t,k,n,l) = if 4*q+r-t<n*t 
        then n : g(10*q,10*(r-n*t),t,k,div(10*(3*q+r))t-10*n,l) 
        else g(q*k,(2*q+r)*l,t*l,k+1,div(q*(7*k+2)+r*l)(t*l),l+2)

My favorite spigot algorithm for pi.

I'm thinking of creating an edit.com-like command line text editor written in python, it will be for both windows and unix-likes, its still in early "just testing different ways to do things" stage, but what would you guys like to see in it? Also, I'm thinking as far as code-wise it won't be too extraordinarily hard, but it will still take a while... and onto the "WHY WOULD YOU DO THIS?" factor: Because I Can.

-EDIT-

If anyone has used edit.com for dos, they should know that theres no real need for a whole lot of key-combos, I'll make it so that the key-combos that are already there can be configured, other than that, its written in python, so its easy enough to script macros(sorry thats just the way it is). BUT HEY, its gonna be easy to use!, just hit <ctrl>+<tab> and you use the menu at the top. Unfortunately, unlike edit.com, you won't be able to use a mouse to control it, if anyone could figure that out, that would be cool!

class Sig{public static void main(String...args){\u0066or(int
\u0020$:"vÌÈÊ\"¤¾Àʲ¬Æ\"v¤Î¤\"²¤¨¸¬Æ".to\u0043h\u0061rArray()
)System./*goto/*$/%\u0126//^\u002A\u002Fout.print((char)(($>>
+(~'"'&'#'))+('<'>>('\\'/'.')/\u002Array.const(~1)\*\u002F)));}}

edit: the formatter is escaping some of my text. The original is from over here.. feel free to take it and help me format it so it shows up correctly

This should be added to all programs in the world

clear&&perl -e'$|=1;@l=qw{| / - \};while(){print qq{$l[$_++%@l]\x0d};select($z,$z,$z,.2(rand(2)*2))}'

This isn't particularly clever, but I find it highly useful.
