I compiled each of these tests using an LLVM-based compiler, since LDC seems to be the best option for D compilation in terms of performance. On my x86_64 Arch Linux installation I used the following packages:
clang 3.6.0-3
ldc 1:0.15.1-4
dtools 2.067.0-2
I used the...
Node.js throws “btoa is not defined” error
...rface, it only provides command line utilities.
If you need to convert to Base64 you could do so using Buffer:
console.log(Buffer.from('Hello World!').toString('base64'));
Reverse (assuming the content you're decoding is a utf8 string):
console.log(Buffer.from(b64Encoded, 'base64').toString());...

Compile time string hashing

Based off of @JerryCoffin's excellent answer and the comment thread below it, but with an attempt to write it with current C++11 best practices (as opposed to anticipating them!).
Note that using a "raw hash" for a switch st...
Binary Data in JSON String. Something better than Base64
...ed as UTF-8). With that in mind, I think the best you can do space-wise is base85 which represents four bytes as five characters. However, this is only a 7% improvement over base64, it's more expensive to compute, and implementations are less common than for base64 so it's probably not a win.
