I'm looking for a library that simplify tempo/bpm audio detection.
Something similar to this http://adionsoft.net/bpm/ , but to use on *NIX machines.
Any language, but preference goes to php, perl, python.
Mixxx uses the BPMDetect class from the SoundTouch library for BPM Detection. There is also another opensource library called BPMDj which is harder to use but is more accurate.
I personally wouldn't rely on either though. Then again I am a hobbyist DJ so I tend to rely more on my ears.
EDIT
There is a much better OSS library called aubio. It can also do beat detection and onset detection.
ANOTHER EDIT
Mixxx has now moved onto the VAMP Plugins set, which is much better, supports aubio and many other beat detection libraries. It also supports key detection and other audio analysis features.
Not a library, but a single class: bpmdetect.{cpp,h} from Mixxx.
Better: http://www.vamp-plugins.org/download.html
Also, if you're already using the GStreamer library, there's the bpmdetect element as a part of the soundtouch plugin, a part of gstreamer-plugins-bad. The python gstreamer bindings are meant to be quite good.

I plan to do some ML programming on Ruby on Rails project and I am searching for any ML framework on Ruby. I searched on Google of course but cannot find any satisfying one so I decide to consult to crowd's wisdom.
I would not say there are any 'good' library for machine learning written in pure ruby since machine learning is fairly computationally expensive. A good library will likely wrap a c interface to a well known library. So you could try and find a good c library and create a ruby wrapper of the library.
An alternative would be to use JRuby and import a java based library. Here is an article about importing weka.

There may be application specific libraries for what you are doing using machine learning? If you are trying to do recommendations try the recommendify gem.
Another alternative is to use a webservice. There is the google prediction api which has a ruby client.

I'm starting to learn network programming in C++ and since the standard library doesn't support networking, I have to resort to one of these. Which do you think is simpler and thus, easier to learn?
They do different things.
If you're looking for HTTP, FTP, and support for a slew of other protocols, then use libcurl. If you want to directly use sockets and implement all your own protocols, then use Boost Asio.
A third choice would be to use the Pion Network Library, which is built on top of Asio. It only supports HTTP, though, and for clients is more of a building block than a ready-made solution.

As a learning exercise I'm building a basic scientific computation environment based on .NET. I'd like the GUI of the app to be much like matlab, in that I have an interactive window, an objects window and the facility to spawn visualisation windows. Intellisense in my command window would be very nice. It seems visual studio itself could almost be used in this manner, is this a viable option? Creating the visualisations within the VS environment seems like the only hurdle. What could I do here?
Eclipse is also an option I suppose but I'd prefer to stay totally with .NET if possible.
Any other suggestions?
You could take a look at MonoDevelop here to provide some help. It is open-source and one of the nicer IDEs.
You could also build something based on GEdit, as it is very pluggable.
Those are the two tools, plus the CLI that I use for .NET development, but I am entirely on Linux/Unix using the Mono tools.
Hope that helps!
I've just discovered VSlab. Its specific to F#, however its a good demonstration of what I would like to be able to do with my own DSL in terms of visualisation and an interactive editor.

I'm into hacking challenges (like rankk.com) and some of the challenges require disassembly and little modifications of PE files.
I'm looking for a disassembler/debugger that is able to dump the strings, walk the assembler code and allow modifications.
My knowledge in this field is very limited so I'm looking for something relatively easy to use and preferably free.
IDA, nothing else comes even close.
IDA Pro
I like OllyDbg. (with a good companion :)
IDA Pro has a nice graph for better understanding of the code flow and the disassembler is amazing. Although i use OllyDbg as JIT debugger and general debugger for MASM.
IDA also has a free version now of their previous version. For light or introductory reversing or getting started it's a great tool.
IDA Pro for common cases, SoftIce for special cases (for example when you need to reverse highly protected application, you can use special SoftIce plugins and so on). I was an experienced cracker in student years :)

I am currently working on software that must emit SNMP traps for SNMP versions 1 & 2 and possibly v3 in the future. I have downloaded several and found them to be either too complex or too simplistic. All I want is to view traps and analyze the data structures within them, and the ability to import my custom MIB's. The best I have found so far is ireasonings MIB Browser, but would be greatful for any nice alternatives.
netsnmp - should do everything you're after, with a variety of language bindings to suit every taste.
The only monitoring tools I've used that utilize SNMP monitoring are Nagios, Zenoss, OpenNMS, and the proprietary product from my company - but they're for full network monitoring.
How many devices are you looking to monitor? If it's only a couple, #Andrew's suggestion of netsnmp may be sufficient.
