@liw in computing i tend to prefer cache hits, in real life cache misses

In colloquial computing Finnish the work for a cache is "kakku", because it's similar in pronunciation. Kakku means "cake". Thus, in Finnish people ask each other how much cake their CPU has.

Language is funny.

Co-authored an update from the @MastodonEngineering team with my friend @renchap - a sneak peek at what is coming in 4.3 (and looking ahead from there). We'll aim to make these updates a regular feature for the blog. Let us know what you think! https://blog.joinmastodon.org/2024/05/trunk-tidbits-april-2024/

And neither I'm against AI, I'm critical towards the business practices and fair use. It is not very intellectual take sides on tech itself but more like how it is applied and controlled.

No need to be perfect. I've quit everything that I don't actually need for anything.

IMHO, good way to protest against bully business practices of AI: exit the most consumer oriented social media. I think it was good time finally quit Facebook fully given the trends. I'm not perfect. I.e. I have still some commercial social media like Slack, Youtube and BlueSky but at least the most heated stuff is gone, or I never was there anyway.

E.g. I think I continue to build my career without LinkedIn, and find the jobs that fit me better through traditional methods of job finding (talking to friends, getting contacted by friend, sending queries and the usual). It is time to go #offtheradar :-)

@lupyuen You can do memory protection also with RISC-V without MMU by configuring so called Physical Memory Protection (PMP) registers in M-mode and running applications in U-mode. So it is memory protection based on physical memory partitioning instead of virtual memory. RISC-V would be a good platform for product low-cost but still quite secure products.

EDIT: Oops, meant to write U-mode, S-mode is one that exists when there is an MMU :-)

@lupyuen I have one SBC for RISC-V (VisionFive2) but would be nice to get one MMUless SBC too (i.e. without S-mode). I.e. kind of RISC-V "arduino".

@liskin @ljs @vbabka do not want to sound like boomer but people should neither "fan" linux nor rust or anything like that. inspiration should come from hardware, domain and stuff like that. they are translatable from kernel to kernel and from language to language, and that is what matter in the end.

@edwintorok @sdbbp right thanks for to great answers! i mean mostly hlt and similar are used to conserve energy (e.g. in PM an similar), and e.g. locks just reschedule so i could imagine that in e.g. linux nop should not cause any actual collateral damage.

i'm just used to specs where opcode does one and only one thing :-)
