How useful/important is REST HATEOAS ( maturity level 3)?
...Someone who has likely painstakingly sniffed web traffic, read HTML pages, etc. to find what links to call when and with what payloads.
And as soon as Amazon changed their internal processes and URL structure, those hard coded clients failed -- because the links broke.
Yet, the casual web surfers ...
Differences and relationship between glActiveTexture and glBindTexture
...r textures, there aren't just targets (GL_TEXTURE_1D, GL_TEXTURE_CUBE_MAP, etc). There are also texture units. In terms of our C/C++ example, what we have is this:
Object *g_objs[MAX_OBJECTS][MAX_LOCATIONS] = {NULL};
int g_currObject = 0;
void BindObject(int loc, Object *obj)
{
g_objs[g_currObje...
A semantics for Bash scripts?
...s to a shell script can be accessed using numbered parameters, $1, $2, $3, etc. You can access all these parameters at once using "$@", which expansion has many things in common with arrays. You can set and change the positional parameters using the set or shift builtins, or simply by invoking the s...
Multiple working directories with Git?
...ng everything except working
directory specific files such as HEAD, index, etc.
The git worktree section adds:
A git repository can support multiple working trees, allowing you to check out more than one branch at a time.
With git worktree add, a new working tree is associated with the repository....
Dynamic type languages versus static type languages
... method interception, dynamic loading,
mobile code, runtime reflection, etc.
In the mother of all papers on
scripting [16], John Ousterhout argues
that statically typed systems
programming languages make code less
reusable, more verbose, not more safe,
and less expressive than dynamic...

...
For a hard-to-guess secret--a password, a crypto key, etc.--never use math/rand; use crypto/rand (like @Not_A_Golfer's option 1) instead.

When and why are database joins expensive?
...ires retrieval of only the keys. In practice, not even the key values are fetched: the key hash values are used for join comparisons, mitigating the cost of multi-column joins and radically reducing the cost of joins involving string comparisons. Not only will vastly more fit in cache, there's a lot...
Do you (really) write exception safe code? [closed]
...If you are catching everything in your top control scope (thread, process, etc.), then you can be sure that you will continue to run in the face of exceptions (most of the time). The same techniques will also help you continue to run correctly in the face of exceptions without try/catch blocks ever...
