Petrakis··on Ask HN: What LaTeX editor do you use?
This is unorthodox, but I use https://www.overleaf.com/ its a neat online editor where I can have my docs stored on the cloud and it has a PDF preview on the side, and you can compile it at the end.
Petrakis··on Ask HN: Recommendations for an Inexpensive and Weatherproof Computer?
The other way around is scratch the weather proof, and just encase it in something weatherproof.

Petrakis··on Ask HN: Monitor a Tennis Court from a Webpage
LoRa fits the low power and its also long range. I have never sent images over it but for sure its possible but unreliable, as its very low bandwith.

I would do some kind of computer vision to identify people, or count them and send that data instead, those operations should be easy on a microcontroller.

Petrakis··on Tell HN: Thanks to YouTube, my 12 year old asked for a knife for his birthday
There are balisongs that are a comb instead of a blade, or trainers.

That said, I too wanted one in my teens, the problem was that I didn't ask for it, I just bought it, and alot of them.

Petrakis··on Ask HN: Did you find something to use your Raspberry Pi 400 for?
I agree with the NUCs, a good compromise ive found is the Lattepanda Delta or Alpha.

I don't have a Pi 400 but I have a similar cyberdeck that has the addition of a screen with the keyboard and board. I use it as a swiss army tool on the go for managing my cloud servers. Its like the classic monitor and keyboard you have hanging on top of your rack, but portable :D

Petrakis··on British Airways Support Asks for Credit Card CVV as Support Verification Code
I think I had the case with jet2, where support for a change of a cancelled flight required my CVV, I called them and told them that I am not willing to provide that information and they should figure out something else. They instantly replied that I can input anything on that form and that it didn't matter and so was it.

Petrakis··on Ask HN: Is anybody skilled in lockpicking?
I won´t define myself as skilled because I am not a profesional, there are people that get paid for that.

Out of curiosity I learned myself playing with locks, its a matter of practice and feel.

The best purpose was impressing friends and also emergency situations that I needed to unlock something that im allowed to (mine or friends).
