Some LaTeX related stuff.
* Instead of searching for symbols in the trusted [Comprehensive LaTeX Symbol List](http://www.ctan.org/tex-archive/info/symbols/comprehensive/symbols-a4.pdf "Comprehensive LaTeX Symbol List"), you may now simply [draw](http://detexify.kirelabs.org/classify.html "online") them. It's surprisingly accurate, and what's more: it's useful and fun. * If you don't know LaTeX that well, but want to write an equation: [draw](http://webdemo.visionobjects.com/equation.html?locale=default "draw") it. * Once you have the code, [get a short URL](http://mathurl.com/ "get a short URL") to show it to your colleagues. * Mentioning colleagues: wouldn't it be nice to work on a manuscript together, without the need of version control systems and the likes? Look [here](http://docs.latexlab.org/ "here") or [here](http://www.sharelatex.com/ "here"). * Finally, an [overview](http://liantze.penguinattack.org/latextypesetting.html#mosc11-slides "overview") which amazes beginners and delights LaTeX veterans like me since it is not only comprehensive but also beautifully done. Chapeau, Lian Tze! By the way: when flipping through the slides of the overview, I imagined a grizzled veteran with thick glasses and a shaggy beard as the author. Now look at [that!](https://lh6.googleusercontent.com/-rJtiJAhcmhc/TjZVFMegNbI/AAAAAAAAJTs/_zRN2O3-rJU/s462/LLT-profile.jpg "that!")
