I'm trying to test bitcoin and I would like to win 1 bitcoins or even 0.00001 just to see how is it to receive and send money.
I visited many faucets, I filled surveys, I watched ads but I never get my payment in bitcoins !
Do you know a website which really sends a micro sum of bitcoins just for me to test ?
Windows 7 / Firefox 50.0
If you just want to see how Bitcoin works use the TestNet, here you got explanations and some real faucets links.
https://en.bitcoin.it/wiki/Testnet
Since mainnet bitcoins are rather expensive, testing there is definitely not desirable. Bitcoin provides you with two other options to develop software against: Regtest mode and the Testnet network. Testnet is a distributed network that operates exactly like mainnet, with some more advanced features being tested. The coins on testnet are not worth anything on purpose so that software can be tested there with realistic conditions. Since testnet coins aren't worth anything there are faucets that will give you some coins.
The other option is regtest mode. This is sometimes called testnet in a box and allows you to spin up an isolated network on your own machine. This network is fully under your control, and you can even generate blocks as quickly as you want. Many projects use regtest mode to run automated integration test suites against their software.

My current project requires us to receive text messages online. It's hard to wade through the search results as many of the are just websites with about 10 numbers for everyone to use.
I am looking for services along the lines of what is being offered at http://www.tropo.com
You can send and receive text messages online on your own private generated phone number within the US or Canada.
Preferably free, just need a few more before I make any decisions
Thanks!
Disclaimer, I do developer evangelism part time at Nexmo.
Here are a few paid SMS APIs:
Nexmo
Twilio
Tropo
You may be able to hack something together that works for free, but you risk that solution being disabled by whatever provider you use (for example, some people send SMS via Google Voice, but I wouldn't recommend relying on that).
Since you're receiving SMS, Nexmo would be a good solution when it comes to price. You only pay for the virtual number (roughly $1 a month), and all incoming messages are free.
Try www.twilio.com they have a good API and it is free while testing.

For a school project our client wants us to create a ZigBee network either using the Texas instruments cc2531 or a XBee. We've got a CC2531 with some sensors from Cleode. In their program, named cleobee, everything works fine. The connection is automatically made, and we don't have to do anything else than turn on the sensors for the connection to be made.
Now we want to use the CC2531 to connect with the sensors without using the Cleode program. Is there a simple way to set up a network? Is there an API we can use? We've found zTool in which we can monitor the usage of the cc2531, but we don't really know what else we can do with it.
Also, we would like to connect an Olimex mod-zigbee-pir sensor with it. Can we do this in the same manner as with the other sensors?
Is there any software available that let's us do this?
If you donot want to use the Cleode program than you can implement the same thing yourself by making changes in the API provided by TI.
Ti has provided all the APIs and you can refer it in the Documents that comes along with Z-stack.
Also sample and Generic programs for zigbee networks are provided which you can modify it according to your requirement.

Do you know any tool that can be used for visually inspecting SMPP packets? A tool that accepts a byte array or string as input and lets us check the fields quickly.
I searched alot but all of the tools were actually code libraries instead of being a tool.
Wireshark has the capability to recognize SMPP packets when given a tcpdump.
Here's a commercial product that can inspect SMPP traffic and apply actions when a byte/string pattern is matched: http://tritux.com/product/NetCop
I'm involved in the tech team behind this product, some of its basic usage is to inspect SMPP traffic to detect deliver_sm PDUs and check for per-subscriber throughput, if one subscriber is sending deliver_sm PDUs more than (let's say) 6 per second than it is more likely to be a malicious mobile terminal (maybe a simbox) flooding the SMSC with MO traffic, NetCop is able to take actions like:
Sending a notification to the user
Blocking (barring) SMS-MO traffic on user (through the telco's intelligent network integration)
...

I have an app and would like to know if there is any kind of API for a service similar to Shazam where I can hold my phone up to a music source and be told of the song guess? It could work well with my app, but I can't find anything about Shazam API and I don't know any other service that does what I want (but am open to anything)
The free and open source alternative is Echo Nest / Echo Print. They claim to have a database of 30 million songs and 1.5 million artists, and they provide free access for both commercial and non-commercial use. Probably worth checking out!
Update: here's the Echo Nest iOS library
ACRCloud supports Music/Audio search engine and SDK for iOS/Android/Linux, which could be downloaded after registration (http://console.acrcloud.com/signup).
There are three tiers:
Free tier, for demo/prototyping
Accelerating tier, for startups
Commercial tier
Audio recognition services are provided by a number of companies, many of which license these services for a fee. None are cheap, requiring significant repositories of signatures / music catalogs and computational capacity. Check out the folks who own the technology used by Shazam - Landmark Digital Services, the makers of Soundhound - Midomi, or Gracenote's MusicID. There are others, but these are probably three of the biggest players currently.
UPDATE (11/8/12): To note, Shazam apparently has reacquired the rights to the recognition technology and Landmark Digital is now defunct. Also, as noted in another answer, Echonest now provides a recognition technology, Echoprint, that for some uses appears to be free.

Is there an API that would let me access my AMEX transactions? How do Mint or any other finance websites export my data? If so, is it free?
Take a look at open financial exchange.
American Express appears to support this.
Mint uses the services of Yodlee (see here), a firm that essentially acts as middleware between banks and companies like Mint.
You might be interested in Yodlee's Account Data Gathering API but it looks like it is something that requires a formal agreement, and access to the API probably needs to be paid for..
MasterCard are also looking at releasing an API (see here) so maybe AMEX will follow suit?
You can find sample code, SDKs, and a variety of other open source work by American Express on GitHub.
