I am debating with my colleague on when to perform code review - before or after unit tests. What is the best practice?
Some factors we might need to take into account (there may be more):
Size of code change - a big change means more changes will result from the code review. If these changes are big than, if UT was... |
After a while, we are hiring again, and I'm reviewing tests for programmers; some of them are a bit out of date. What are some of the FizzBuzz-type questions for web developers and SQL? That is, not too trivial, but still solvable in five to ten minutes with pen and paper and without Google?

I would like to make my programs much less of a hassle to extend or create, I am imagining a scenario where the end user has a variety of check box options that affect how the program interacts.

If I were to build a Twitter or Facebook application using pure client-side technologies like HTML and javascript, how would I mask/hide my API keys?

Google App Engine has been great for trying out ideas and learning stuff, but so far I haven't seen much confidence in the community in using it for production applications.
One significant issue that has come up over and over again is that when things go wrong, it's nearly impossible to actually talk to anyone at Goog... |
Recently, I was developing a set of coding standards for our company. (We're a new team branching out into a new language for the company.)
On my first draft, I set the purpose of our coding standards as improving Readability, Maintainability, Reliability, and Performance. (I ignored writability, portability, cost, c... |
While I agree that catching ... without rethrowing is indeed wrong, I however believe that using constructs like this:

Here's a question for me that really makes me wonder every time I start designing and developing a thick-client desktop application.

I am contemplating a few different techniques for organizing code for a larger web application.

Why standard C++ doesn't respect system (foreign or hardware) exceptions?
E.g. when null pointer dereference occurs, stack isn't unwound, destructors aren't called, and RAII doesn't work.
The common advice is "to use system API". But on certain systems, specifically Win32, this doesn't work. To enable stack unwinding... |
