Numpy first occurrence of value greater than existing value
...
Just a word of caution: if there's no True value in its input array, np.argmax will happily return 0 (which is not what you want in this case).

What's the difference between using CGFloat and float?
...e based on the performance characteristics of early PowerPC CPUs. In other words, you should not think that float is for 32-bit CPUs and double is for 64-bit CPUs. (I believe, Apple's ARM processors were able to process doubles long before they went 64-bit.)
The main performance hit of using doubles...
What is difference between functional and imperative programming languages?
...n imperative languages you tell the computer how to change bits, bytes and words in it's memory and in what order. In functional ones, we tell the computer what things, actions etc. are. For example, we say that the factorial of 0 is 1, and the factorial of every other natural number is the product ...
What is the difference between the remap, noremap, nnoremap and vnoremap mapping commands in Vim?
...tml#vim-modes-intro). The abbreviation 'c' is for 'command-line'. In other words, by default: map! lhs rhs recursively maps lhs to rhs for insert + command-LINE modes. That is unless the remap default option is explicitely disabled with set noremap[!] in ~/.vimrc. In that case mapping would not be r...
Why is my Git Submodule HEAD detached from master?
...loned in submodules-recursive way or submodule being initialized? In other words your own repository you update the file in which is not always profiting from submodule config updates put to '.gitmodules'. In my understanding '.gitmodules' is a template for config created while repo is being cloned ...

@Bill Karwin: JOIN keyword was not a part of proprietary standards until the past more recent that it may seem. It made its way into Oracle only in version 9 and into PostgreSQL in version 7.2 (both released in 2001). Appearance of this keyword wa...
Relationship between SciPy and NumPy
...most (but not all [1]) of NumPy's functions in its own namespace. In other words, if there's a function named numpy.foo , there's almost certainly a scipy.foo . Most of the time, the two appear to be exactly the same, oftentimes even pointing to the same function object.

Why does this method print 4?
...eated another version where every repeated data point is removed. In other words, only points that are different from the previous are shown. This makes it easier to see anomalies. https://www.google.com/fusiontables/DataSource?docid=1XG_SRzrrNasepwZoNHqEAKuZlHiAm9vbEdwfsUA

Difference between objectForKey and valueForKey?
...w, but sarcastically. KVC doesn't look all that useful. In fact, it looks "wordy". But when you want to change things at runtime, you can do lots of cool things that are much more difficult in other languages (but this is beyond the scope of your question).
If you want to learn more about KVC, ther...
Why can't decimal numbers be represented exactly in binary?
..., but we can't even deal with all rational numbers (such as 0.1). In other words, I don't think it's really to do with countability at all :)
