My ecig mod (or box how some call it) started to missbehave, it started at random not liking more and more batteries and generally it was good time for replacment. Fast forward, im at shop, and I have few options, i dont want to cheap out becouse I know how it ends, and I want reaible box for longer and I can pay a little more for that.

So there was few quite competetive options, but most of them had build quality i wasnt fan of, some even plastic outter shell, magnets which tend to break off, but their feature list was quite competetive, and there most expensive of all (400 pln +-90ish $) that seller presented me had (seemingly) no features. No menu even. But build quality is solid buttons feel are just better, and it looks like it could survive longer than half a year. Fine, i shell out what it looked missing features for solid build quality.

I go home, rtfm, and wtf? "Before use update firmware with XYZ software". Okay, done. But hmmm what is that?

It has plethoria, absolute TON of customization but from PC program. Hell yeah, that was fucking good choice and seller missed whole selling point of this box. Like literally, he didnt know its best feature. I can go as far as customize entire GUI on that small screen. Its been awhile since I did my last pixelart thingy but monochromatic so not too bad :)

Why do any tutorials on any kind of technology start their projects on ports like 3000/8080/4200/5000 and so on? Why not start them on port 1/2/3/65536/etc.? Are these chosen tutorial ports free to use? Any special meaning? I've looked up a table of ports and many ports have a specific purpose but are still (mis)used for that arbitrary whatever project?
