Are there some nice libraries (and if so, what are they) for automating website queries using Haskell.
Basically I want to get a form, fill in some values and get the results (and naturally, do this repeatedly).
I'm not sure whether you're looking for a web scraper or just a way to make GET/POST requests. In the latter case, there's Network.HTTP, or the Haskell libcurl bindings. In the former, you could look into HandsomeSoup, or one of the other HTML parsing libraries (I've never actually used these myself, so I can't recommend a specific one).

I am new to functional reactive programming and I would like to know how different packages compare in Haskell. They all seem to have slightly different approaches and I don't know enough to choose between them.
I also think that the available information for some of the packages is out of date. This previous Stack Overflow question recommends either netwire or reactive-banana but currently netwire won't install with stack because it depends on an out of date profunctors package.
So basically, for a beginner, how do the various FRP packages compare against each other? And which are best for GUI applications and which are best for simulation/game applications?
Thanks,
I found this link very helpful for comparing FRP libraries. It gives example code for a simple application written in each library.

Does anyone know of any open source search projects written in Go?
I want to implement a simple site search for my site and am looking for a web crawler, but more specifically, a search algorithm written in Go.
Any ideas, projects, or suggestions?
For the web crawler part, there`s gocrawl: https://github.com/PuerkitoBio/gocrawl

You could try the suffixarray implementation in Go's standard library: http://golang.org/pkg/index/suffixarray/
Take a look at godoc how it can be used.

I want to do mindmaps which are of the quality of mindmeister that you could include picture and links etc and would be able to export it reasonably well and print it.
I love X-Mind. I don't know if it does what you need, but I only use a small subset of it and still it rocks!
It has a very complete free version that never expires and doesn't contain crapware.

I prefer Freeplane but FreeMind can do the same things:

I had to put a captcha on my form. In favor of user-friendliness and internationalization I went with a simple math question.
Since that's almost too simple for bots to crack, I decided to put the entire question in ASCII. Is this relatively safe or can it still be easily bypassed by most bots?
I have: & #87; & #104;& #97;& #116; & #105;... and it will output "What is 4 + 1?"
Generate an image of the math question instead. And probably apply some simple transformations if you need more security.
The HTML escape is easy to bypass as it is a computer readable format. For a bot detections scheme to be successful the task must be easy for a computer to generate, easy for a human to solve, and difficult for computer to solve.

"A programmer, computer programmer or coder is someone who writes computer software" from Wikipedia
If you do frontend development using jQuery/CSS/HTML do you call yourself a programmer? If you develop PHP applications that deal with databases, do you call yourself a programmer?
Are you only a programmer if you write applications for desktops and mobiles? Is the web a place where the line between developer and programmer stops?
I imagine this question might be closed off or moved but if you look at the most viewed question on Stack Overflow its a question about Free C Learning material :)
If you are writing a significant amount of Javascript code, then I'd say you are a programmer.
(If you are just copying snippets of Javascript you've found elsewhere, then that doesn't count.)
If you use jQuery, then you use JavaScript, which is a programming language.
