PHP global in functions
... on around in those parts.
Pointless, since this ecosystem is pretty much 20% of roughly entire internet. Apparently, it DOES work, it does its job and more. Which means its the same for the global keyword.
Another good example is the "iframes are evil" fundamentalism. A decade ago it was heresy t...

Is Unit Testing worth the effort? [closed]
...only half as much of the code base gets trashed (~25% = ~4.4% unit tests + 20% of production code).
My point is that you have to communicate that you understand that balance between too little and too much unit testing - essentially that you've thought through both sides of the issue. If you can co...
How to generate a random string of a fixed length in Go?

Getting rid of rand.Intn() and using rand.Int63() instead gives another 20% boost.
Masking (and repeating in case of big indices) slows down a little (due to repetition calls): -22%...
But when we make use of all (or most) of the 63 random bits (10 indices from one rand.Int63() call): that spee...

where it is 20% FASTER (or more!) to
allocate a new, multi-kB array than
