Answer Snippets (Read the full thread at stackoverflow):
You should use.
As other said.
You should always use List<TypeOfChoice> whenever you want to store any simple string or no or any basic data.
When using List, you don't have to do that.

When should I use /dev/shm/ and when should I use /tmp? Can I always rely on them both being there on Unices?

You should use /tmp unless you have a very good reason for using /dev/shm.
Not on machines strapped for memory.

So you should program against these situations.

IMHO, it shouldn't be an exception at all.

I'm coding in Erlang and a I am bit unsure about how to approach error handling, especially after seeing the ugly errors Erlang always returns.

Errors and exits seldom should....
The purpose of this error is to crash, and should.
When that one is raised, you should try and stop, functions that can't match or don't exist, etc.
To be able to handle (maybe because they occur often) .

I’m planning on using Ajax with my web application, but as I’m novice and don’t have much experience I wonder when ajax should and when should not be used? I plan to code with jQuery/php if it makes any difference.

AJAX should not be used.
This can save quite a bit of bandwidth.
When you should and when you shouldn't use AJAX has very little to do with the underlying including all the data you've seen before.

In the examples you show, it should be first URL-escaped, then HTML-escaped:
<a href.

The details.
The abstraction for a new one I should still be able to drive the car without knowing that the engine changed.
It means that if the details change they should not affect the abstraction.

Use triggers for when you dont have an alternative.
Use your tables and stored procedures to deal with the issue .
Triggers are obscure and can be hard to debug for the developer .
I wouldnt use a trigger for something like this.

In this case, I think both options should be supported, both Begin*()/End*() and Async on Asynchronous Programming , there's a good clue as to the thinking that should help you decide whether the method should be asynchronous....
Is critical.
