All I can say is my hair down there is the thickest of anywhere on my body, both in terms of individual hair diameter and in terms of hair follicle density per area.
I've never used Nair on my junk, but IME it doesn't do shit to my leg hair unless I leave it on at least twice as long as it says. In other words, if you have thick hair you probably should use something else.
You need to get the whole area done repeatedly, the follicles only die if they get zapped during a certain phase in their growth cycle. Typically laser sessions are spaced about a month apart to allow time for previously killed hairs to fall out and the remaining ones to make some progress in their cycle, you can expect to lose like 10-20% of the remaining hairs with each session.
Having recently started estrogen, I can confirm that my beard growth has slowed dramatically and my once receding hairline is gradually filling itself back in.
Almost everything is Debian - my servers, my desktop and laptops, my family member's computers, the living room media player. Only exceptions are my router (OpenWRT) and my Steam Deck (SteamOS).
There are other YouTubers who have managed to make meaningful chips (on the order of 1000 transistors) out of basically a garage setup with salvaged and/or improvised equipment. I would be shocked if this guy can't do better than that with his much more sophisticated setup.
I kept using it until about two months ago, when votes stopped showing (presumably due to some API change), but there were plenty of minor things before that - for example, it stopped being able to save images almost a year ago.
A lot of people paid money for it, only for the dev to go AWOL pretty soon afterwards. Most people probably wouldn't mind him abandoning the project, except for the fact that they paid a subscription (or a large one-off payment), only to get abandoned without any communication at all.
this is the exact opposite of what the other comment says
