Recently, I started learning SQL, and I am looking for ways to practice and solve exercises.
I searched, but I did not find any good exercises to solve, they were easy and not complicated .
Did anyone know where I could practice and solve complicated exercises in SQL ?
Please advise.
Thanks
Finding to learning basics of Sql commands is available in many sites. So i am sharing basics, intermediate and advance sql resources.

Are there companies using this technology in production? I would like to find some benchmarks and use cases. We are considering switching to deepstream with mongo from our current firebase setup. But I want to make sure it can handle and scale well enough to meet our demands.
Additionally, if you are using it, what kinds of tech have you used to load test it?
Maybe you can take a look here where it is stated that:
4 companies reportedly use deepstream.io in their tech stacks, including all, DelightSoft, GraphicWeave, Adinject
Unfortunately, I can not answer your other questions, but you could contact the companies for further info :)

I have a set of emails which i need to anonymize before I can do any analysis on it. Since sensitive data may be disclosed in the emails, like referring to people, or providing phonenumbers etc.
The tools i have found so far, only uses tables, and mask this, which is quite straight forward to do myself, but it does not solve my problem.
So i am looking for a tool or library, that can help me solve this. I would assume it need to do some Natural language processing in order to analyze how the text is built up, and where refferences to people are being mentioned. I would also appreciate any good articles in this area

I hate to ask questions like these, but where can I learn about this particular part of the Orchard API?
The documentation doesn't go into half as much detail as it should/could so would be very grateful if somebody could point me in the right direction of an example/usage explanation of Query() and it's overloads. I can't accurately form a query without it.
The Training Demo module has a lot of examples: https://orchardtrainingdemo.codeplex.com/SourceControl/latest#Controllers/ContentsAdminController.cs
Beware though: https://orchard.codeplex.com/workitem/20131

Is there an open source alternative to Mosek?
Basically, I'm looking for large scale convex optimization solver packages.
Thanks!
EDIT:
Forgot to mention earlier, problem is non-linear; mostly quadratic, but occasionally may need non-quadratic constraints + non-quadratic objective
There are many packages, mostly with Matlab interfaces, like SDPT3, SeDuMi, and CVX. I believe the first two have their backends in C. The websites of these projects link to other packages. What language did you have in mind?
Does GLPK suit you?

I'm interested in Collaborative Developing and I was wondering if there are alternative solutions than using UNA (example video) from N-Brain. Free would be even better, but I guess that's not an option which such technology.
PS: The main future I'm looking for is working real-time with multiple persons in the same code.
If you're in Mac world, SubEthaEdit is a good option. Not free, but €29 isn't bad.
After some further searching around I have found Gobby, seems to be much better than MoonEdit.
Don't think there is any better free program that supports developing more than color coding.
I hope to have helped others too by this question.
Thanks to Charlie I have found MoonEdit, I'm still looking for better alternatives though...
