Why can't decimal numbers be represented exactly in binary?
...k with base 10. Today we might be able to justify the overhead but in the 1970s when the standards were being set, it was a big deal. Trying to do it without the direct support of processor circuitry is even worse, expect orders of magnitude differences in speed.

scrollIntoView Scrolls just too far
...
This works for me in Chrome (With smooth scrolling and no timing hacks)
It just moves the element, initiates the scroll, then moves it back.
There is no visible "popping" if the element is already on the screen.
pos = targetEle.style.position;
top = targetEle.style.top;
targetEle.style....
Compiling with cython and mingw produces gcc: error: unrecognized command line option '-mno-cygwin'
... +1 This is a useful answer. For extensions using numpy, I also had to hack options inside the numpy/distutils folder, both for mingw32compiler.py.

More elegant “ps aux | grep -v grep”
...
brilliant hack (I think I should call it that, since the aux / grep authors probably did not think of this scenario.)

Autocompletion in Vim
...dieguitoweb ACP doesn't work with every filetypes by default. You have to "hack" it to make it work with JavaScript, ActionScript and PHP. Here I explain how I do it. And here is another hint for PHP.

Is there a reason that we cannot iterate on “reverse Range” in ruby?
...
And 5 is outside the range.
You can simulate reverse iteration with this hack:
(-4..0).each { |n| puts n.abs }
John pointed out that this will not work if it spans 0. This would:
>> (-2..2).each { |n| puts -n }
2
1
0
-1
-2
=> -2..2
Can't say I really like any of them because they ki...
Repeat Character N Times
...wsers, you can simply write:
"a".repeat(10)
Before repeat, we used this hack:
Array(11).join("a") // create string with 10 a's: "aaaaaaaaaa"
(Note that an array of length 11 gets you only 10 "a"s, since Array.join puts the argument between the array elements.)
Simon also points out that accor...

How to format a java.sql Timestamp for displaying?
...
java.time
I am providing the modern answer. The Timestamp class is a hack on top of the already poorly designed java.util.Date class and is long outdated. I am assuming, though, that you are getting a Timestamp from a legacy API that you cannot afford to upgrade to java.time just now. When you...
