Some of the categories are quite surprising, for example:
space-nasa-tesla-rocket-launch-star-CHINA-nuclear as space;
ruby not as programming;
com-http-www-EMACS-LIST-org-book-pdf as junk;
Those seem very specific, or plain wrongly classified. Maybe you can show them individually, just as a big dump of generated graphs? No need to make another post about it though, but i'd like to see them in context. Thanks!
I think you're mixing up what topics are. The actual topics as generated by LDA are the concatenated word lists (actually distributions of all words in the corpus, of which i concatenate the top 8 words to generate a meaningful descriptor of the topic). So server-client-http-request-service-ruby-connection-user is one topic / word distribution, in which "ruby" happens to be 6th most probable word, likely because it appears a lot in posts on servers, web services etc. It does not mean ruby the word itself is classified to be server related. Same applies to the other examples you gave.
The categories/domains I simply assigned manually, to show how one could possibly interpret these word distributions that LDA generated.
Not sure what you mean by a new classification approach. There is no classification here, since there are no labeled documents. This is purely unsupervised topic modelling. The topics are mathematical objects. How they are later named or grouped for better human readability is a subjective matter.
Latex is pretty great. Use the Beamer packege. However, its drawback is that all slides look very similar, and it's very time-consuming to experiment with discrete slide layouts.
For most users I'd say this is one of the few scenarios where you really really want a graphical editor.
I'd be happy if they could just show the contents on the website (or even if they could show PDFs) so that you don't have to click "View Raw" to access them.
Then don't upvote it. Asking that people prescreen their submissions to not offend your subjective definition of "interesting" or "informative", is introducing a chilling effect.
What makes you say that? Have you ever used Windows 8 for any length of time?
I have it on 2 tablets and one of my workstations and to sum up my experience with it: It's awesome! Nothing else even comes close.
It all starts with the most basic interactions. For instance - there's no other window manager that lets you completely control the OS with just the keyboard and in such a consistent, logical and discoverable way as Windows.
What's wrong with meatheads? As if getting in Bodybuilding-shape didnt require the same dedication as programming. I'd even say true bodybuilding is far more demanding than being a programmer. Not necessarily requiring as much math, but nobody in his right mind would compare against that.
Also, this program will not help you get in shape.
