I wonder very often, whenever I am any good at computers, and I should actually be proud of any of the stuff that I do, or not

I try to infodump about something that I know about, entities ask me very obvious questions, and I realize I actually know nothing about it

Just how does GEN12 handle control flow after vectorization? How do SIMT ISAs like RDNA3 or NV170 handle it? Why do I not know this? My friends are praising me for doing GPU drivers, but I don't even know something as basic as this...

Am I accidentally lying to them and making them believe that I'm better than I actually am? I might be wrong about some of the stuff I said, I might be too confident in being able to do stuff that I cannot actually do...

I'm genuinely just, fake, and deceiving my friends into thinking I'm better than I actually am, no matter how hard I try not to. I try my best to describe what I can do in a way that they don't misunderstand but... I fail, and they think I'm good because I end up being misleading by having many trivial prototypes that do nothing impressive.

Like, I say "I wrote an http server in assembly with no libraries!" but used to forget to add the pretty important part that it doesn't parse the request, can only handle one request at a time, and has a hardcoded inline response. Not much of an HTTP server, is it... It's literally just a few syscalls and one small loop. The most trivial thing imaginable, the kinda thing anyone and their cat can do, the thing I should beat myself up for not doing way earlier, when I was like 12

Yesterday, I misremembered how Java multiple dispatch works. I was supposed to know it correctly. I knew the JVM ignores the Signature attribute on the Code attribute, and only cares about the method descriptor, which does not include any generics info, as generics are a Java thing, not a JVM thing. So I was confused why I was remembering that you can MD List<Integer> and List<String> while knowing there is no way to represent that in a class file (unless you do name mangling and generate a hidden dispatcher method and... Stuff Java doesn't do. I think. Unless they added that...)

I still feel stupid about it. I'm supposed to be good at Java... I do it for over 8 years... I actually have (had?) some confidence in it...

I don't even know how the damn GCs work, or the internals of the JIT. Stuff I should know but don't because I am too scared to look into it.

I'm getting my ass beaten by IETF RFC 1951 just because I lack some basic knowledge about compression algos, and feel completely and utterly useless when someone trivially understands the whole thing in a few hours while I'm failing for years.

I'm stupid. And a liar.

타자기 구멍이 고장나서 충전 표시가 안되는데 일단 전압높은 케이블을 꽂아둬서 충전이 되긴 하는지 알아보는 중 근데 우리집에 그만한 물건은 없어서 닌텐도 스위치 충전기 꽂아두었어요

Ein guter Vorsatz ist ein Pferd, das oft gesattelt, aber selten geritten wird.

- mexikanisches Sprichwort

In dem Sinne: Änderungen werden angegangen, wenn die Entscheidung dazu gefallen und die Bereitschaft da ist. Nicht, weil der Kalender umgeblättert wird.

올해도 "경제적참견시점"은 챙겨 봅니다. 재정학자가 30분 자기 썰 푸는 컨텐츠는 한국에서는 거의 유일할 듯.

MBC 시선집중의 유튜브 컨텐츠들이 충실한데, 이 코너와 외교안보를 다루는 "세계눈 우리눈"은 강추합니다. 매주 챙겨볼만한 가치가 있습니다.

【健之堂虎乳芝強肺免疫配方特約】香港天文台在今日（1月1日）下午4時20分發出寒冷天氣警告，預測本港未來一兩日早上天氣寒冷。

明日（1月2日）市區最低氣溫約在12度左右，新界會再低兩三度。

天文台提醒，市民應注意保暖，多穿禦寒衣物，並應保持室內空氣流通。如有認識獨居的長者或慢性病患者，請間中致電或探訪他們，看看是否需要提供幫助。

市民使用暖爐或暖風機時，請注意消防安全，遠離易燃物件，及避免電力負荷過重，並切勿於室內生火取暖。

當使用舊式氣體燃料熱水爐時，需確保室內有大量清新空氣。
