I heard Swift was a gay language. Incedentally I've only heard this on /g/.

I made a machine learning algorithm in swift implementing back-prop neural nets and it's faster than the same thing i did in C++.

never underestimate the power of the optional type or the function type

Static is not a myth or a wive's tale. I have constant problems with my PS4 controller losing connection just because I walk over the USB cord without touching something metal first. I actually completely fried my MX518 by reaching over and touching it after sitting down in my chair without realizing I had picked up a static charge.

As for internal components, it depends on your environment. If you're in a very low humidity environment, I would say to definitely be careful about where and how you clean your components, maybe use a wrist band.

that's not static. what you've described are the effects of the urea in your gamer NEET sweat

My odroid xu4 got static damage after the warranty ran out. Some things are more sensitive than others.
