I've started self-hosting email in ~2021. It took about 6 months (of mostly waiting) to clean up reputation of IP I've gotten (was in a few spam lists). After that - it was incredibly easy to maintain. It's literally just running mailcow update every now and then and that's it. So, if you are willing to fight for a bit in that initial stretch - no, it's not hard; yes, you can self-host your email.
It told me my ~10 year old js project was 50% AI generated. Yeah, this is more or less the same as "AI text detector" stuff that won't work reliably (but people who don't understand LLMs will still use it to blame others)
Those games are usually brilliant - but those are very rare. Like "once in a few years" kind of rare IMO. While that is a valid approach, I play way more than that haha!
What I found interesting with Vaporlens is that it surfaces things that people think about the game - and if you find games where you like all the positives and don't mind largest negatives (because those are very often very subjective) - you're in a for a pretty good time.
It's also quite amusing to me that using fairly basic vector similarity on points text resulted in a pretty decent "similar games" section :D
Built vaporlens.app in my free time using LLMs (specifically gemini, first 2.0-flash, recently moved to 2.5-flash).
It processes Steam game reviews and provides one page summary of what people thing about the game. Have been gradually improving it and adding some features from community feedback. Has been good fun.
I've started self-hosting mailcow (dockerized) on a Hetzner VM ~6 years ago or so. It took about 6 month to clean the rep of my IP address as it unfortunately been in spam lists previously - but after that, it's been a pretty smooth sailing. And all for a measly ~10 euro/mo including daily backups.
