I want to extract important terms from a text and create a domain specific term set. Then I want to learn how these words are used in text, positively or negatively.
Do you know any open source project which will help me to accomplish this tasks?
Edit:
Example Text:
"Although car is not comfortable, I like the design of it."
From this text, I want to extract something like these:
design: positive
comfort(able): negative
For parsing the text and getting the parts of speech you want, there are lots of toolkits
http://incubator.apache.org/opennlp/
http://www.nltk.org/
etc.
Check out http://en.wikipedia.org/wiki/Sentiment_analysis for ideas about finding how words are used positively or negatively, if what you mean by that is connotation. I don't know of any solid platforms for doing this, but maybe you can tell us more about your problem for some ideas.
In absence of a toolkit that'll do this for you, you might find that getting NPs and the ADJs linked to them would be sufficient. You'd also need negation detection. I've used this ohnlp.sourceforge.net (build on Apache UIMA) and it comes with a negation detection algorithm that is moderately decent.

I want to be able to show complex math expressions like this...
...without having to use images or javascript.
It seems like that there are HTML characters for most of the actual glyphs, so the challenge is to scale and stack them into the correct configuration. This seems doable, but not practical for a large number of expressions. My instinct is to put together a series of classes that combine to result in a "math CSS framework".
Before I open this pandora's box, I wonder if this is a problem that has already been solved. Google doesn't seem to think so, but maybe you know otherwise.
NOTE: I love snazzy HTML5 and jazzy CSS3 tricks as mucha as the next guy, but I need IE8+ :-(
Have a look at MathJax.

I want to do a presentation using HTML5. If some of you already use a good HTML5 framework to make slides please can you give me the links.
I like this one :
http://slides.html5rocks.com
But I want to have more information before choosing one.
reveal.js
deck.js
html5slides
I personally prefer reveal.js. Simple enough to easily create slides, but still powerful enough to do everything I want it to do.
Well I have used and been impressed by impress.js:
http://bartaz.github.io/impress.js
Its output is very similar to Prezi.
Bunkr is super convenient and fun to use, and nice enough.
But I haven't found a slide show framework that can handle math.
Hopefully they'll add this feature soon!
Update: reveal.js can use MathJax to handle math, as described here.

I'm a beginner when it comes to programming, and I have the nasty habit of googling anything I want to do, or don't understand. When I have to work offline it's of course really hard for me.
I'm trying to make a handbook out of any good cheat-sheet and refcards I've found.
So far I have a Vi cheat sheet, some docs from Addedbytes and a few about standard OS commands.
The question is:
What documents are absolutely essential to avoid being useless while offline. (The more synthetic, the better)
Unless you want to lug around a whole binder of cheat-sheets (which then poses other problmes such as searching for the info), i'd recommend a usb key with the cheat-sheets regarding
the OS you're working on
the language you'll be working with
the technologies you'll be building upon
If you really insist on being exhaustive, a site like http://www.cheat-sheets.org/ may help you go on a cheat-sheet splurge, and you may want to have a look at other answers on stackoverflow

I have heard about "evil" and based HTML, but I have never seen any real-world examples. It seems that nowadays, most websites are using 's and CSS for layout. Van anybody provide an example of this "evil" code? It should be a real-word example.
Ironically. w3schools.com
Sure, take a look at the source code of Google. Its tables and font tags galore. Obviously their intentions lie in the area of efficiency as opposed to semantics. I wouldn't call it evil...
If you’ve received any slickly-designed HTML e-mails, they’re likely to be an unmaintainable mess of <table> and <font> tags under the hood. (Having written and maintained a couple, I speak from bitter experience.)
Lots of nonprofit sites are like this. Here's one I designed a few years ago (but did not develop) and it makes almost exclusive use of tables for the entire site.

I need a library that can extract text from handwritten paper once I scan it. Normal Latin text.
It can be a free solution or even something I have to pay for, as long as it handles handwriting for block letters (not cursive).
There isn't an OCR program capable of recognising hand-written text well; it's not something that can be solved easily.
There are, however, strong commercial systems which are possible to train if the variancy isn't too great. For example, take a look at ABBYY.
