Is it worthwile to learn assembly language? [closed]
...thermore, the conventional wisdom is to not try to hand-optimise assembly most of the time but let the compiler worry about it. When you see some examples of the twisted things that compilers generate, you will better understand why the conventional wisdom holds.
Example: LFSRs run fast with the ro...
Detecting that the browser has no mouse and is touch-only
...S know when a user plugs in a mouse/connects to a keyboard, but doesn't expose it to JavaScript.. dang!
This should lead you to the following:
Tracking the current capabilities of a given user is complex, unreliable, and of dubious merit
The idea of progressive enhancement applies quite well ...
Can I Replace Apache with Node.js?
I have a website running on CentOS using the usual suspects (Apache, MySQL, and PHP). Since the time this website was originally launched, it has evolved quite a bit and now I'd like to do fancier things with it—namely real-time notifications. From what I've read, Apache handles this poorly. I'm w...
Difference between static memory allocation and dynamic memory allocation
..., especially if we start considering that the compilation machine and the host machine might not be the same or might not even be on the same architecture.
It may be better to think that the allocation of static memory is handled by the compiler rather than allocated at compile time.
For example...
ssl_error_rx_record_too_long and Apache SSL [closed]
...ubimage was right on the money for me. It suggested changing the virtual host tag, ie, from <VirtualHost myserver.example.com:443> to <VirtualHost _default_:443>
Error code: ssl_error_rx_record_too_long
This usually means the implementation of SSL on your server is not correct....
What does a type followed by _t (underscore-t) represent?
... and so on. These new types are formally defined in <stdint.h> but most often you will use <inttypes.h> which (unusually for standard C headers) includes <stdint.h>. It (<inttypes.h>) also defines macros for use with the printf() and scanf().

Android AsyncTask threads limits?
...me user logs in to the system, I also use database in the phone. For all those operations (updates, retrieving data from db and etc.) I use async tasks. As up till now I didn't see why I shouldn't use them, but recently I experienced that if I do some operations some of my async tasks simply stop on...
When should the volatile keyword be used in C#?

don't attempt to write any low-lock code except for the most trivial
usages of Interlocked operations. I leave the usage of "volatile" to
real experts.

Should URL be case sensitive?
...you are submitting. It is up to the server how to handle the request URL. Most of web servers are unix/linux and that means most of web servers are case sensitive.
