I have to perform load tests on a video streaming server does anybody know a good tool that can help me? if it were free or open source, it would be perfect
Actually there is nothing special in testing MPEG Dash as it is a subset of HTTP Live Streaming so any load testing tool which supports HTTP protocol will fit.
If you're looking for a specific recommendation check out Apache JMeter, it is free, open source, has relatively large community and you don't have to know any programming language as JMeter tests can be created using GUI approach.
Check out Load Testing Video Streaming with JMeter: Learn How article for detailed instructions with regards to the most popular video streaming protocols load testing using JMeter
You can use this commercial plugin for Apache JMeter.
It is available through jmeter-plugins manager and allows you to reastically test all flavors of MPEG-DASH.
It simulates how players download manifests, chunks, init segments and provides video related metrics.

I'm looking for a flexible monitoring tool, which should be able to:
Monitor public web endpoint and:
Validate REST API response body.
Validate response codes.
Monitor Azure resources: Cloud Services, Web Apps, SQL servers, VMs etc (Optional)
Support of custom monitoring scripts. For example, there is a PowerShell script which performs some checks and returns response if
service healthy or not.
Provide availability/performance metrics based on monitoring statistics.
Raise alerts and send notifications
Tool should have a modern UI and support of multiple monitoring projects, each project should have own isolated settings.
Currently we are using MS application SCOM (System Center Operations Manager), but it's a very old tool and has a poor documentation and UI. But a very flexible and can monitor a lot of thing out of the box.
Basically, is there something better and modern than SCOM?
We are using HP-BSM, though expensive, it's very flexible and with many capabilities. It has every functionality that you wrote in your question.

I am iOS developer. I am new with doing object tracking feature. I have searched many links based on tracking real objects. But I have found many links like image tracking, image matching and all. Likewise I would like to track the real world objects.And also I have gone through a site below:
http://developers.arlab.com/me
It helps a lot for tracking images, image matching etc. But not specified any object tracking. If anybody suggesting good tutorial or having any sample source code of object tracking, please share.
Advance Thanks for your support.
You can use the OpenCV framework for Object Tracking. There are many nice tutorial and documentation on internet.
Below i have listed some.Please check if this helps you

OpenCV is released under a BSD license and hence it’s free for both academic and commercial use. It has C++, C, Python and Java interfaces and supports Windows, Linux, Mac OS, iOS and Android. OpenCV was designed for computational efficiency and with a strong focus on real-time applications...

You can download the SDK from here
Demo Github project

These are some examples you can find many more.

How can I test my Rails app with N concurrent users?
These simulated users will do some actions like upload/download files, etc.
Are there any frameworks or free tools that support this?
ab(Apache Benchmark) is made for that. Here is an example:
https://github.com/igrigorik/async-rails
I use jMeter, although the UI is a little rough IMO. I ended up sharing a lot of code between my easyb (Groovy-based) specs and a mini-DSL I used to create jMeter config/execution files (XML) so redundancy between specs and load testing was reduced. The same should be doable in Ruby as well.
JMeter allows concurrent testing, ramp-ups, all sorts of stuff. I don't know if it does everything a commercial tool does, but I've used it for a long time on a wide range if apps and it's been, more or less, satisfactory.

I have a client who is looking for a solution to integrate cctv with a (any) ANPR solution that can,I assume recognize the number plate of cars and store in a database and has the ability to post this data to other backoffice applications, crm, marketing app. etc.
Is there any ready software to do this ? Or your recommendations ?
Check out OpenALPR (http://www.openalpr.com). It is free and open source and is very fast and accurate. Given an image it will recognize all the license plates and give you the text of the characters.
Since it's open source and written in C++, you should be able to integrate this with your application fairly easily.
You can look at:
How to recognize vehicle license / number plate (ANPR) from an image?
There seems to be at least a few ANPR solutions. My advice is to be prepared to buy something if you want a reliable and fully integrated solution.
Avigilon currently has a License Plate Recognition Kit. It comes with either one or two lanes. The kit is the camera in a special housing along with a software package that captures the license plates and stores them in a database. You could then search for license plates or create a watch list for specific license plates. You can read more at www.Avigilon.com.

There has been some talk of Website performance monitoring tools and services on stackoverflow, however, they seem fairly expensive for what they actually do. Are there any good opensource libraries for automating checking/monitoring the availability of a website?
If you just want to know if your server is serving out content or not, take a look at Montastic. I use it, and am pleased. Plus its free!
It will ping your site periodically, and if it doesn't get a 200 status, it lets you know.
Intelligent website monitoring by simulating a human user is done with Sahi + OMD.

I have always used Zabbix especially for critical web sites. It uses MySql for the database and it has a PHP frontend. Of course it is open source and it is very flexible. It uses servers to stick data in the database and agents collect the data and send it to the servers. It is very scalable with this respect. I cannot recommend this software enough. I have all kinds of monitoring going on, not just web servers.
