...ch typically results in average bitrates in the upper part of the sane CBR range (where 320 kbit/s is the maximum, probably a bit beyond the point at which lossless compression becomes more appropriate).

How can I get the sha1 hash of a string in node.js?
...ance whatsoever that your text contains Unicode symbols outside the latin1 range (e.g. emoji!), do not use binary! Using binary or latin1 in the encoding will lose information and increase the likelihood of collisions! Try the snippet above with these two for example: ❤ and ⑤

...SON
with additional subclasses.
While the set of sub-classes is fixed, the range of operations we may want to do on a JSON blob is
unbounded: parse it, serialize it, pretty-print it, minify it, sanitize it, etc.
Thus it makes sense to model a JSON data structure as a closed sealed trait

What is a 'semantic predicate' in ANTLR?
...ens (a lexer rule instead of a parser rule) that will match numbers in the range of 0..999. Now in the parser, you'd like to make a distinction between low- and hight numbers (low: 0..500, high: 501..999). This could be done using a disambiguating semantic predicate where you inspect the token next ...
Is it faster to count down than it is to count up?
...appen on some hardware depending on what the compiler can deduce about the range of the numbers you're using: with the incrementing loop you have to test i<N each time round the loop. For the decrementing version, the carry flag (set as a side effect of the subtraction) may automatically tell you...
