Which way is best for creating an object in JavaScript? Is `var` necessary before an object property
...ant to create several similar objects. In your example, Person (you should start the name with a capital letter) is called the constructor function. This is similar to classes in other OO languages.
Use way 2 if you only need one object of a kind (like a singleton). If you want this object to inheri...
Should *.xccheckout files in Xcode5 be ignored under VCS?
...luding this file in my repos since it has been introduced, I have recently started to remove it from all my repos. This thing is creating merge conflicts all the time, mostly in projects that include my own frameworks as submodules. And then I gain nothing from this file since I use git for submodul...

... unique device ID. We run the check service once, when the application is started for the first time. We then generate a 512 character hash for the key and the stored value that is compared against in SharedPreferences from there on out.

Why call git branch --unset-upstream to fixup?
... an upstream". (Remote-tracking branches is a terribly flawed term—I've started using remote-tracking names instead, which I think is a slight improvement. Below, though, I'll use "remote-tracking branch" for consistency with Git documentation.)
Each "remote" is simply a name, like origin or oc...
Should I use past or present tense in git commit messages? [closed]
...ce Git). "Revision" messages or commit messages in the present tense only started making sense in truly distributed projects - see the first point above.
People not only read history to know "what happened to this codebase", but also to answer questions like "what happens when I cherry-pick this...
What's Pros and Cons: putting javascript in head and putting just before the body close
...in parallel. While
a script is downloading, however, the
browser won't start any other

In some situations it's not easy to

Drawing Isometric game worlds
...rder to amend this problem, the inner for-loop's order must be reversed -- starting from the highest value, and rendering toward the lower value:
tile_map[][] = [[...],...]
for (i = 0; i < tile_map.size; i++):
for (j = tile_map[i].size; j >= 0; j--): // Changed loop condition here.

What is the maximum amount of RAM an app can use?
..., your regular Android Profiler will be enough for you.
Usually, an app starts with 50Mb of RAM allocation but instantly jumps up to 90Mb when you start loading some photos in memory. When you open Activity with a ViewPager with preloaded photos (3,5Mb each) you can get 190Mb easily in seconds.

How does C compute sin() and other math functions?
...ion.
When |x| > 2, none of the above algorithms would work, so the code starts by computing some value closer to 0 that can be fed to sin or cos instead.
There's yet another branch to deal with x being a NaN or infinity.
This code uses some numerical hacks I've never seen before, though for all...
