How can I properly handle 404 in ASP.NET MVC?
...sax file.
Step 1: Have a common place for 404-error logic
This is a good idea for maintainability. Use an ErrorController so that future improvements to your well designed 404 page can adapt easily. Also, make sure your response has the 404 code!
public class ErrorController : MyController

Is gcc 4.8 or earlier buggy about regular expressions?
...an implementation of regex_search that only does "return false" was a good idea?
It wasn't such a bad idea a few years ago, when C++0x was still a work in progress and we shipped lots of partial implementations. No-one thought it would remain unusable for so long so, with hindsight, maybe it shoul...
PHP “pretty print” json_encode [duplicate]
... so I'd like to add line breaks in and "pretty print" the JSON output. Any ideas on how to do this? My only other alternative that I can see is to not use json_encode at all and just write the file contents manually and add in my own line breaks for each line.

Convert light frequency to RGB?

General idea:
Use CEI color matching functions to convert wavelength to XYZ color.

Clip components to [0..1] and multiply by 255 to fit in the unsigned byte range.
Steps 1 and 2 may vary.

Is “inline” without “static” or “extern” ever useful in C99?
...wer also answers your question, I think:
What does extern inline do?
The idea is that "inline" can be used in a header file, and then "extern inline" in a .c file. "extern inline" is just how you instruct the compiler which object file should contain the (externally visible) generated code.

What is the purpose of a stack? Why do we need it?
...the code very terse.
UPDATE: Some additional thoughts
Incidentally, this idea of drastically lowering costs by (1) specifing a virtual machine, (2) writing compilers that target the VM language, and (3) writing implementations of the VM on a variety of hardware, is not a new idea at all. It did no...
How do you calculate the average of a set of circular data? [closed]
...turning point (which is where the derivative = 0).
Here we will apply the idea of minimise the squared difference to derive the common arithmetic mean formula: sum(a[i])/n. The curve y = sum((a[i]-x)^2) can be minimised in this way:
y = sum((a[i]-x)^2)
= sum(a[i]^2 - 2*a[i]*x + x^2)
= sum(a[i]^2)...
A simple example for someone who wants to understand Dynamic Programming [closed]

The idea behind dynamic programming is that you're caching (memoizing) solutions to subproblems, though I think there's more to it than that.
There are many Google Code Jam problems such that solutions require dynamic programmin...
