Get your own LaTeX-enabled wiki in the cloud with Instiki on Heroku

I guess you all know what a WikiWikiWeb (short: wiki) is, it's a website where you can easily add new pages and modify existing ones. MathOverflow is some kind of hybrid between Q&A and a wiki, since users with enough reputation can edit other people's questions and answers. MathOverflow made the Markdown syntax very popular, and people got used to using LaTeX online. Some of my readers surely know the nLab, a collaborative wiki on n-categorical math(ematical physics) and stuff. The nLab runs on a software called Instiki, which is a wiki written in Ruby (an intepreted language similar to Python, and somewhat similar to Lisp, Perl and JavaScript; which is often used for web applications like wikis). The good thing about Instiki is that it supports editing pages in Markdown syntax with embedded LaTeX, so it is able to support your personal knowledge management needs. In addition, Instiki is small (thus not many bugs are to be expected), fast and the code is quite readable; something I wouldn't say about MediaWiki, the software behind Wikipedia.

In this post, I will tell you how to run your own wiki like the nLab. [UPDATED 2013-01-07; easier fix]

A survey of GNU/Linux shortcomings

A long time ago, I switched from Micro$oft Windows to GNU/Linux. Since Ubuntu, I even recommend GNU/Linux to non-computerfreaks. Sadly, Ubuntu is not perfect. In particular, some applications are still missing. What follows is a wish-list of future Ubuntu features/applications. Some of these are available on Windows or Mac OSX, most aren't.

How to manage news?

It is vital to get at least some news. You need to know about political developments, to be informed when it's time to cast your vote (or, if you're not living in a democracy, when it's time to protest). You need to know about developments in your work, so you can adapt and don't risk losing your job because you're too old-fashioned. You need to know about economy if you're investing money. You need to stay informed about every project you want to participate in. Maybe you even need to know what pop-stars do, because if not, you have nothing to talk about with your friends.
How to cope with this information overload?

How to manage papers?

I have lots of PDFs on my hard-disk, and most of them is half-read or unread. Since I'm studying mathematics, these PDFs are lecture notes, research papers, my own notes and several more-or-less relevant books. How do I organise them? It's a problem.

Managing contacts

How to manage contacts?

Managing contacts has never been easy - there are various kinds of data floating around (phone numbers, email addresses, private addresses, work addresses, birthdays ...) and the data is always changing ("Hey I got a new phone number ... "). It's better to keep all contacts in one place and to take back-ups of your precious data.
