Using Django time/date widgets in custom form
...
The growing complexity of this answer over time, and the many hacks required, probably ought to caution you against doing this at all. It's relying on undocumented internal implementation details of the admin, is likely to break again in future versions of Django, and is no easier to im...
Vertically align text next to an image?

In order to get this to work correctly across the board, you'll have to hack the CSS a bit. Luckily, there is an IE bug that works in our favor. Setting top:50% on the container and top:-50% on the inner div, you can achieve the same result. We can combine the two using another feature IE doesn't...
What's the best way to model recurring events in a calendar application?
...but all the solutions I've come up with to handle these events seem like a hack. I can limit how far ahead one can look, and then generate all the events at once. Or I can store the events as repeating and dynamically display them when one looks ahead on the calendar, but I'll have to convert them t...
In C/C++ what's the simplest way to reverse the order of bits in a byte?
...
See the bit twiddling hacks for many solutions. Copypasting from there is obviously simple to implement. =)
For example (on a 32-bit CPU):
uint8_t b = byte_to_reverse;
b = ((b * 0x0802LU & 0x22110LU) | (b * 0x8020LU & 0x88440LU)) * 0x101...

What does curly brackets in the `var { … } = …` statements do?
...x. This makes code much more succinct.
For example:
var ascii = {
a: 97,
b: 98,
c: 99
};
var {a, b, c} = ascii;
The above code is equivalent to:
var ascii = {
a: 97,
b: 98,
c: 99
};
var a = ascii.a;
var b = ascii.b;
var c = ascii.c;
Similarly for arrays:
var ascii =...

Which encoding opens CSV files correctly with Excel on both Mac and Windows?
...xcel as far as I've seen. But OpenOffice / LibreOffice do not require this hack anyway (line-breaks in cell contents work just fine, whereas loading from text file / using the text into columns assistant in Excel does not properly handle line breaks in cells).

Why is \r a newline for Vim?
...
Good point! So this is a hack around \0 - backreference to 0-th nested group - whole regexp. This is a very good answer, but it makes me dissapointed, that I can't use \r in replacement... (meaning: insert #(13), for example in a "normal" file (== un...
