Where can i find database, phone numbers masks for mobile operators, or just web site, where i can detect mobile operator by phone number?
I know this out of date, but you would need to do something called a HLR lookup via a sms gateway, InfoBip for example.
In the UK, you cannot do this. Numbers can be ported from operator to operator, it's all very fluid. Each operator will know how to route these numbers between themselves, but they don't expose that routing to outside parties.
Not in Australia - mobile numbers might be handed to operators in blocks, but they belong to the user and can be ported to any carrier the user chooses to use.
Of course, there are still ways to look up an individual number and find out which carrier it's on - there have to be, in order for the call to be routed to the appropriate carrier. You're not going to get access to that without investing a significant amount of money to set up a telco though.
All of this is almost certainly irrelevant to you as you didn't say you were specifically interested in australia; but then again, you didn't say you weren't interested in Australia either.
I found such a service which seems to provide an API for lookup of the operator in many countries around the world: http://numberportabilitylookup.com/

I need to categorize domains into different categories that offer the best use of a domain name.
Like categorizing 'gamez.com' as a gaming portal.
Is there any service that offers classification of domain name like Sedo is doing?
All the systems that I am aware of manage a list, somewhat by hand.
Using a web-filtering proxies (e.g. WebSense) for inspiration, you could scan for keywords contained in the domain name, or in web content/meta tags at the specified location. However, there are always items that seem to match more than one category, or no category, and these need deeper analysis.
Eventually you end up building your own fairly complex logic, maintaining a list by hand, or buying a list from someone else.
SimilarWeb API does that.
It's really straight forward and returns a given domain's category from a URL.
If these are new domains or not used domains. There isn't any information on the internet yet. You can make use of a mechanical turk, like: https://www.mturk.com/ .
You could post an task with your list and possible categories. The downside is this will cost you money.
If these are domains that are already in use you can use a bookmark service as xmarks or delicious. Retrieve all public bookmarks from that domain and count the number of tags. The most used tags will indicate a category of the domain.
I think https://tools.zvelo.com/ has pretty accurate categorization.
For example gamez.com comes back with Hobbies and Interests as IAB-TIER-1 and Video & Computer Games as IAB-TIER-2.
It also provides information if the domain is brand-safe, is it malicious or illegal content?

I'm looking for answers to a few general questions as to how point of sale (POS) software and hardware generally works in brick-and-mortar stores. I realize there will be many edge cases given the sheer number of solutions out there, but I'm looking for answers on the most common setups...
So, here it goes:
I realize that there are several standards for hardware interface standardization (OPOS, JavaPOS, UnifiedPOS). However, what is most common these days?
When a credit or debit card is scanned, does the scanning device take care of processing the card, or is it transmitted to the main POS terminal, which then connects to the processing service for processing?
Are there any standards on software for the main POS terminal systems?
How are product identifiers generally stored - barcode, ASIN, proprietary standard?
Thanks in advance!
UnifiedPOS, as the name implies, appears to be the most universal standard. JavaPOS, as you might expect, is Java language specific, while OPOS is WIN32/COM based, which suggests that it is an older standard.
OPOS, JavaPOS, and POS for .NET are all based on the UnifiedPOS standard, and they all appear to have broad support. So your choice comes down to which programming language you want to use to develop the platform.
Hardware written to the UnifiedPOS standard should work with any of these platforms. The UnifiedPOS committee says that 36 different point-of-service peripheral types currently support the standard.

I enjoy the game of Go (also known as weiqi in China or baduk in Korea). I want to create a program (an evaluation function) to play it.
I would prefer if the framework handled two important tasks:
Handle rules for the game, including captures, ko rules, and final scoring.
Handle communication between a server like KGS and my program.
Also, my home machines run Linux or Mac OS X; I cannot use any only-Windows platforms.
Thank you!
GNU Go is a great open source Go program. Its evaluation function is well-documented and it provides an easy way to output the explanation for every move the program made. You can either replace the evaluation function from scratch with your own, or tinker with the existing one.
Open Go is an open source tool with code for communicating using the Go Modem Protocol. I believe that's what you need for the second part of your question.
This is an old question, but for people out there interested in an Android implementation of Go (Baduk/Weiqi) take a look at my project on https://github.com/amgreg/AndroidGo
It's a simple validator with a user-interface attached. Drawbacks are: No AI; no scoring; no server connection.

I'm writing a small helper utility for obscure software that is used at a local shop. Basically, I would like to know if anyone searches for anything associated with that software and if publishing my work on the Internet would make any sense. I entered the name of the software into Google Trends, but my terms "do not have enough search volume to show graphs" despite the fact that Google lists 250,000 results for the software name, or 35,000 if I explicitly remove terms such as serial and warez from the search.
Does anyone know of alternatives to Google Trends? Or of another way to find out if people search for a particular keyword?
I found what I was looking for.
Google AdWords Keyword Tool
Yahoo Clues is a service similar to Google Trends. But I don't think it's as effective for any category that is non-entertainment.
If you don't get an answer here, another place to ask might be The Business of Software.
Google Trends was also telling me there wasn't enough data for my query. I found Google Insights to do job nicely. And unlike the AdWords tool mentioned in the author's answer, it actually shows a trend.
Here's an example which shows the emergence of 3 terms with too low of volume to show up on Trends: #bigdata, #datascientist & #datajournalism.
Here's a related SO question.

What is the FIX protocol for financial institutions?
FIX protocol is a protocol for application communication between financial institutions. Mainly stock exchanges, brokers, market-makers, dealers.
http://en.wikipedia.org/wiki/FIX_protocol
Took 2 seconds to find using Wikipedia/Google.
You have a Java tag on this question so I think you might be looking for a FIX communication library in Java...http://www.quickfixj.org/
The FIX protocol (Financial Information eXchange) is a series of messages for the electronic exchange of financial messages. Most large banks and investment banks use it to accept things like orders from external entities such as hedgefunds etc.
A FIX message is basically a tag/format string. Each tag is a number which cross-references to an entity. For example:
8=FIX.4.1
8 means FIX version.
There is an XML variation of the messages, called FixML, but last time I looked it wasn't extensively used.
FIX Protocol is a :
free open source protocol used for electronic trading.
tag value based protocol e.g. 8=FIX4.4 where tag 8 is Fix Version and FIX4.4 is value.
Supported by most of the broker for equities and fixed income trading.
base on TCP for transmitting FIX messages.
provides mechanism for recovery and replay.
