seems like it's just human nature to feel enormous excitement and worry at the same time whenever a fancy new tech comes out (only to realize later it wasn't as good or bad as expected)
/me stares at his stock account and wondering when to pull out
(but yeah it's not just about the stock market)

mathieu@fosstodon.orgI can't wait for either the bubble to burst or the machine taking over. This inbetween is such a sad pathetic state.

cdown@fosstodon.orgCompressed swap is a common lever to improve memory density, but there's a lot of confusion about how to best use it out there, and many people treat zram/zswap as two flavours of the same thing when they are really far more nuanced.
So what works, what doesn't, and why? In this article I go over the tradeoffs, the work we are doing upstream, and a little about what the future looks like. I am, as always, happy to answer questions :-)

@vbabka @kernellogger That's the beauty (and also ugliness) of vagueness; it can get specific in any direction :)

@ljs
that's awful indeed.
the maintainer should transfer some power and responsibilities (ok, this is already...) to rightful folks and trust/respect them :/

@ljs There's nothing more frustrating than something that doesn't change no matter how hard you try, especially when it's something you're really passionate about and care about deeply.
More than anything, I just wish you wouldn't burn yourself out and would take a little rest :'(
I really appreciate and keep being impressed by what you and David have been doing, but at the same time I can't help worrying that you're taking on too much of a burden...

42 Seoul, a campus of 42 [1] (which started as École 42 in Paris), has announced that they'll close this September.
During the COVID period, I've been taking computer science classes at university remotely while working on 42's assignments in person at 42 Seoul. (Yeah, that was quite intense!)
What I learned there wasn't knowledge itself, but how to approach problems I had never once thought about before, through discussions with peers. That learning process contributed greatly to my growth as an engineer in my early twenties (fun fact, hyeyoo is the nickname 42 gave me!).
These days, sadly, it feels like there are more and more people giving up on logical thinking (AI isn't going to replace logical thinking and problem solving skills, at least in the near future :/)
It's quite sad that 42 Seoul, a school that cultivated the ability to learn and think, and approach challenging problems, is closing its doors due to practical reasons.

Oh nooooo… :/
yeah, it happens sometimes (I got the LSFMM flu last year)
Take some good rest and get well soon!
