@Dennis Can you please replace Braille with [this version](https://tio.run/##jVXfb9owEH5O/oprp1KbwEqgW7uF8DCplSZN2tOeOjQZxwFrmRM5gVbb@NvZnZO0hUasiAd8933fnX0/kMOllLvdG21ktk4UTMsq0fnb1czfM2V6QTZ/bUq9NCoBuRIWZG42ylbswMr9P75nVbW2BpiEHoweLkccplMIfQ/o87e1j66c/fLQfo342eylfXLt7JPI3/r@JtcJqAcl15U6yKFfiUINoNS/1Y8KksKltA/RpjQDEHYZ@V6D0wXEMIp837tf6UwBCwJdcECqR2h0kuydLuYumRShnocKcOgZpSTilfe6kitgRK5lPClKRYDRR8xcVwzZPIKFVeJn9Mwfot/dAYJGOikgoGznHejxI3r4CvQE0fsgTN/RO8CXj9KPyvOa1QF@h2ASjSGkqnaD3teg4VHQFYK0U6LnDSDswFzXmGGLGXdgPhAmBXbi7sD/qyle4o/qLxr8K@XlC/hR9aSrUktVUf@yrrZRSCjWtX@f2IVOu@StMAnjcEb@9Blp6@MXh06b…

@stasoid Can you put it in a GitHub repo?

Or I'll make one for the organization. In any case, I'll add it tonight.

@stasoid Is rand() % 0xff correct? I assume it should be either rand() % 0x100 or rand() & 0xff.

@Dennis Yes, I prefer it to be on TIO's github.

@Dennis I don't know.

Pavel

18:52

I wonder if & 0xff is faster than % 0x100 or if they both get optimized to the same thing

Dennis

tape is of type unsigned char *, so it can be removed entirely. gcc probably does.

@Dennis could we add Swift 3 to TIO? Swift 3 tolerates quite a few useful things for golfing that Swift 4 doesn't

Pavel

@Downgoat I don't believe Swift 3 runs on Linux

Downgoat

@Pavel wait really? H*ck

Pavel

Actually ignore me I'm wrong

Dennis

19:00

The only reason we have Swift 4 is because somebody made a repo for it. Before that, I tried (and failed, miserably) to compile it myself.

Downgoat

hm ok

Pavel

There are tarballs at swift.org/download/#releases

Dennis

19:13

@Dennis Surprisingly, it does not. rand() & 0xff gets optimized to rand(), but rand() % 256 actually modifies the return value (not using div, of course) before the assignment.
