What is “stdafx.h” used for in Visual Studio?
...instead of starting from scratch, the compiler starts compiling from the already saved results of compiling everything in stdafx.h.
I don't believe that this trick is unique to Microsoft compilers, nor do I think it was an original development.
For Microsoft compilers, the setting that controls th...
How are zlib, gzip and zip related? What do they have in common and how are they different?
... and are in varying, small amounts of use. The only method in truly widespread use in the ZIP format is method 8, Deflate, and to some smaller extent method 0, which is no compression at all. Virtually every .zip file that you will come across in the wild will use exclusively methods 8 and 0, like...
Why doesn't GCC optimize a*a*a*a*a*a to (a*a*a)*(a*a*a)?
...e results, e.g. same results on any compiler. Floating point numbers are already not exact. It is seldomly inappropriate to compile with -fassociative-math.

Erlang's 99.9999999% (nine nines) reliability
...ong says here:
The AXD301 has achieved a NINE nines reliability (yes, you read that right, 99.9999999%). Let’s put this in context: 5 nines is reckoned to be good (5.2 minutes of downtime/year). 7 nines almost unachievable ... but we did 9.
Why is this? No shared state, plus a sophisticated error...
Ruby custom error classes: inheritance of the message attribute
...
raise already sets the message so you don't have to pass it to the constructor:
class MyCustomError < StandardError
attr_reader :object
def initialize(object)
@object = object
end
end
begin
raise MyCustomError.new("...
google oauth2 redirect_uri with several parameters
...otect against CSRF, I'll try to show a proper method. Rather than passing (read exposing) data it should be kept local. Hydrate it before the request and re-hydrate it after a validated request. "Validated" here means that the state-nonce of request and response match.
You need some kind of temporar...
How to create REST URLs without verbs?
...se "RESTful URLs" is therefore nonsense.
I think you should do some more reading on what REST actually is. REST treats the URLS as opaque, and as such doesn't know what's in them, whether there are verbs or nouns or whatever. You might still want to design your URLs, but that's about UI, not REST....
What is a “context bound” in Scala?
...ept of 'is a'). A context bound (A : C) says 'has a' about a type. You can read the examples about manifests as "T has a Manifest". The example you linked to about Ordered vs Ordering illustrates the difference. A method
def example[T <% Ordered[T]](param: T)
says that the parameter can be see...
Why Large Object Heap and why do we care?
I have read about Generations and Large object heap. But I still fail to understand what is the significance (or benefit) of having Large object heap?

Performance difference for control structures 'for' and 'foreach' in C#
... the difference to performance won't be significant, but the difference to readability favours the foreach loop.
I'd personally use LINQ to avoid the "if" too:
foreach (var item in list.Where(condition))
{
}
EDIT: For those of you who are claiming that iterating over a List<T> with foreach...
