Could you recommend an open source library written in F# which provides generic types for FA construction and basic algorithms (NFA to DFA transformation, FA minimization ...)?

My first thought would be to use the state machine monad, which has be blogged/written/discussed/produced several times, a couple of references are below.

although this doesn't give you the translations you want...
Might be a place to start.

Probably not what you are looking for but a quick and dirty way to get some FA things working would be to write an equivalent context free grammar for your FA then using fsyacc?

Jolt.NET
It does not fulfil all your requirements: It's in C#, and it does not seem to support translation to DFA or minimization. At least it's usable from F# and could be used as a starting point. I've never used it myself, so I can't vouch for its suitability or quality.

As an old C/C++, C#, Java, JS, PHP programer, I just couldn't get used to Objective-C. The reasons are obvious. I want to continue developing iOS applications and continue using Xcode storyboards. But I seriously need an alternative to Objective-C, is there any powerful tool or framework alternatives that could help me get away from Objective-C?
By powerful alternative, I mean useful enough to use most of the device methods/functions easily and has a lot of online resources, tutorials, examples on it.
I would very, very strongly recommend that you get a good Objective-C book, or work through the Stanford iOS development course on iTunes U. Without Objective-C, you will get a lot less help with other languages, you won't be able to understand code samples, you won't understand the iOS documentation.
Try http://xamarin.com/ios - this allows you to write in C#. Personally I've used all those languages as well (other than C#) but actually prefer Objective-C.

We recently added some policies to out fairly large Lua project, which also includes some stricter style guidelines than we used to.
The problem we are facing now is to convert the whole codebase to the new style guidelines, which is a lot of work. I started reformatting the code and got tired of it after about 5 files out of hundreds.
My idea is to use a code formatter, which automatically does this for me. However, the output format needs to be according to our style guidelines and not any different style. We also have some unusual guidelines, like a space before the opening parenthesis for the argument list in a function definition.
All this makes it fairly hard to find a suitable formatter. Does anyone know about one that meets all my criteria? Any help will be greatly appreciated.

Can you recommend lexer and parser generators for Common Lisp? I have seen the following lists on CLiki, but most on the lists seem to be in their alpha stages:
http://www.cliki.net/LEXER
http://www.cliki.net/parser%20generator
So it would be helpful if you could share your good or bad experience with any of them or recommend other alternatives. I prefer a tool which is similar to traditional lex/yacc tools for other languages, but other approaches will be also welcome.
There is smug (documentation), which provides "functional" parsers that are supposedly similar to some of Haskell's parsing libraries.
Also, if you're looking for Lex/Yacc style parsing, look into lispbuilder, which has lexer and yacc packages that seem mature.

Is it better to implement blob(connected component) handling manually in openCV or are there any good libraries for the same? I found cvblob and cvBlobsLib? Are these libraries used on a standard scale?
I also looked into this and decided in the end to write my own CCL routine. It seems like a serious omission from OpenCV and no doubt a lot of people are "reinventing the wheel" as a result. Note however that you may be able to use findContours, depending on your exact requirements - see this question.
You should take a look at the new opencvblobslib. It has great features like multi core support.

What encryption algorithm is better to use?
client-Delphi, server-Python.
Recommend please simple algorithms and libraries ..
If you are looking for simple algorithms (not simple encryption) then two come to mind:
XTEA
RC4
Both are really simple and could be easily implemented in any language and both are very fast. XTEA is also secure. At least if you are not looking to protect national secrets :) I have an XTEA implementation for Delphi that works under newest delphi versions. Look here.
I also found a Python version: http://code.activestate.com/recipes/496737/
This question is far too open ended.
Your best bet for using the same library in both Delphi and Python is mcrypt. It contains a sizable cipher suite. I recommend AES / Rijndael for just about everything. It's a nice block cipher and is used almost everywhere.
You can also try the Delphi Encryption Compendium. It features the most popular algorithms and is quite easy to use due to it's OO layout.
