• C# Object Declarations

  - by pm_2

• Stopping infinite loops of alerts in Mozilla

  - by Christy John

  This may be dumb question. But somehow this engaged me for sometime and after some basic research I couldn't find an answer. I was learning JavaScript and a code I wrote had an error and has been outputting infinite loops of alerts. I tried the normal shortcuts like Ctrl + C and Ctrl + Z but they didn't work. So I was thinking if there is any solution to this other than ending the browser process (like by doing a Ctrl + Alt + Del).

• What is the best way to use whitespace while programming?

  - by Emmanuel Smith

  I'm fairly new to programming and from learning I have seen different ways of formatting code, comments, etc; and have been recommended on different techniques.

I would like to know the same thing for commenting as well.

• Asp.net mvc small amount data storage

  - by Trimack

  Hi there, I am writing some learning tests (i.e. what's the answer for...; choose correct options...). Now my question is, how should I store them. SQL db seems quite an overkill, but I really don't know what would be the best choice if I wanted to select random subset of questions etc. Perhaps some simple xml files? Thanks for advice.

I might be wrong in my perspective. Please suggest possible ways to change logic in the code at runtime.

• why make non-privileged methods?

  - by aharon

  I'm learning JavaScript, and I can't understand why you'd make methods that aren't 'privileged,' that is, that aren't defined in the constructor but rather the class' prototype. I understand the idea of encapsulation and all, but you never encapsulate parts of a class from the rest of it in most of the OO world.

• Is learncpp.com good for beginners?

  - by Dream Lane

  In my search for a good, freely available resource that will teach me C++ I stumbled on http://www.learncpp.com/. My question is for intermediate to experienced C++ programmers... Does this site seem to be a good resource for a beginner to learn C++ from?

• What's the best UML diagramming tool?

  - by eplawless

  I'm trying to choose a tool for creating UML diagrams of all flavours. Usability is a major criteria for me, but I'd still take more power with a steeper learning curve and be happy. Free (as in beer) would be nice, but I'd be willing to pay if the tool's worth it. What should I be using?

• Recommended reading for bioinformatics

  I'm keen on learning about bioinformatics. I am ideally looking for a short course introduction, with some practical tasks I can get my teeth into immediately to see if there is any interest in it for me. I already have a good understanding of molecular biology, so I should be able to skip most of the foundational work. Any suggestions?
