How would you implement word pronounciation functionality in an online dictionary site ? for example lets say, oxforddictionaries.com. they have this functionality where you can listen to how the given words are being pronounced.
Well, do I have to record each word and save it in a folder and then link it up with the database? If that's the case then probably I would have to create a million .wav or any sound files for the million words in the database. or how would I sort this out ? How do u think oxforddictionaries.com implemented this functionality ?
There are two approaches
Record each word (wav/mp3)
Synthesize the sound based on the phonetic spelling.
The latter one feels quite unnatural, but a cheap solution. I know only about the Longman dictionary, they definitely record each word (and even whole sentences), with a couple of speakers, so you don't get bored..
Unless you want to do the synthesis in a plugin/widget, you probably end up with sound files with both approaches. You can simply play them with html/html5/flash players.

I'm writing a simple antivirus in C.
I've got some malware samples and I want to extract signatures form them.
Any idea how to extract them?
Retrieving a "signature" could be as simple as generating a digital signature via hashing for the virus(es) respective binaries. MD5 or SHA.
I.E. implementing the following functionality in your code that I'm sure you've already started...:
md5sum virus -> md5hashofvirus |
md5sum virus2 -> md5hashofvirus2
Complete dossier of md5sum available here.
MD5 implementation in C available here.
However any modification to the file would render this method of detection useless (albeit that's the end goal of encrypting a virus). An actual "virus signature" that modern AV's use is
"any sequence of bits that can be used to accurately identify the presence of a particular virus in a given file or range of memory."
As that level of analysis makes it a bit harder for malware manufacturers to hide the "identity" of the malware.
www.agusblog.com/wordpress/what-is-a-virus-signature-are-they-still-used-3.htm is something that I feel you should read.
www.labri.fr/perso/ly/publications/viro.pdf if you're looking for something a little more indepth.
If you'd like more information, try sharing a bit more yourself.

Hi i need a non deterministic constraint satisfaction problem tool, because i need different solutions with the same input of the problem. Someone knows about a tool with this characteristic?
I only know tools like Gecode (c++), Choco (Java) and Curry (Haskell) that i think work in deterministic way.
If what you want is to get some random solution, most CP tools have some support for using randomised heuristics. For example, the standard Gecode branchers have options for this, for example INT_VAR_RND and INT_VAL_RND for integer variables. To get a different search each time, make sure to set the seed uniquely.
Note that using random heuristics will not give you any guarantee of the distribution. For example, your problem might have only two solutions, but almost all random choices might lead to one of the solutions giving a very skewed distribution.
Are you trying to do Pareto optimization (aka multi-objective optimization) and let the user choose one of the pareto optimal solutions?
People have done this with Drools Planner (java, open source) by simply replacing the BestSolutionRecaller class. See this thread and this thread. Planner 6.0 or 6.1 will provide out-of-the-box pareto support.
Similar to what Zayenz said, you can try Minion with the flag -randomiseorder.

I was just wondering why I can not just set everything as static? I think if I set something as a static then it has a better access time than other variables that haven't set as static..
But I assume there might be a problem and that is the reason why people are not doing this.. What are the problem could be? Thanks in advance..
Consider a class Person and all your friends are instances of that class. Now consider they all have names, their names are their attributes.
Now, if that name attribute was static, all friends would have the same name.
That's why we have instance variables too.
If you make everything static, then there only exists a single copy of it in the entire program. This can be a problem when you want multiple computations of the same thing to go on in parallel or if you want to track multiple copies of the same logical object at the same time.
As for the access time, one should consider correctness first and foremost, then optimize later. Additionally, optimizations should be based on actual measurements, not speculation. If you actually measure how long things are taking, that is pretty much never going to be the optimization you make.

Visual Basic .NET
C##
etc
C#? With two pound signs?
It's on so many of these programming résumés we're getting -- from random people -- listed as a qualification.
Any ideas what these folks are talking about? Is this convention an accidental holdover from C++, or something?
EDIT/ANSWER: Turns out the corporate résumé management system converts the "C#" that applicants specify to "C##". That is just fantastic.
My guess is you shouldn't hire them.
Looks like a recruiter who doesn't know what he is talking about is trying to impress you.
That résumé speaks for itself - little attention to detail. Not good for a programmer...
If it's on "so many" I'm willing to bet that the candidates don't know what they are talking about. Similarly, I have seen 'C+' listed as a language as well.
It's not uncommon for people to list as many languages on their resume as they can, because the Bad Ones think that even knowing the name of the language gives them a foot ahead of someone who doesn't. This is obviously a flaw in logic.
I can't remember exactly where I heard this story before (someone's blog, maybe someone will remember) but the exact situation is described. A candidate comes in with a resume listing all of these languages. As the interviewer asks the candidate to demonstrate their knowledge of the language by writing some code, the candidate freezes. When the interviewer asks why, the candidate responds with "I didn't say I knew how to write in those languages, just that I know of them!"
I received a resume before has this line in the list of experiences
C \ C+ \ C++ \ C#
:)
C Sharp - now even sharper!

I don't know if I am a bad programmer because I often make mistakes when outputting information on a site, things like "thanx for subscribing to our service" instead of "Thanks for subscribing to our service".
I think this is because I usually don't concentrate on the spelling, my main focus is to get the functionality running perfectly. Please give me your opinion, do you concentrate on the spellings or the functionality?
If I'm writing a message which will be visible to users, I'll make sure it's clear and correct. If I'm writing a message which will only be visible to other developers, I'm slightly less careful - in particular, typos aren't really a problem, so long as I express myself clearly.
Fortunately my spelling/typing/grammar is reasonably good anyway, so I don't need to think too hard about this, but I think it is important for customer-facing text.
Developers often aren't very good at writing messages for users. It can be hard to put yourself in the position of someone who really has no idea about what's going on in the background: they just want to get their email (or whatever it is) working. If you're lucky, you may be able to get a technical writer to help compose appropriate text.
IMO attention must be paid to both. Cool logic and reliability are no excuse for crappy texts.
You could separate checking the resource from changing the source. When you do changes first change the code, test everything, then proofread the resources.
The CTO at my last job was dyslexic, and a completely brilliant programmer and manager. Every now and then I would go and make a spelling correction to one of his method or variable names (C# handles the refactoring pretty well) and it didn't really matter that much.
When there's user interface work it's much more important to spell things correctly coz it looks very shabby to have a misspelled UI.
