sgerenser··on C++20 Modules: Practical Insights, Status and TODOs
The fact that something doesn’t scale past X cores doesn’t mean that it is I/O bound! For most C++ toolchains, any given translation unit can only be compiled on a single core. So if you have a big project, but there’s a few files that alone take 1+ minute to compile, the entire compilation can’t possibly take any less than 1 minute even if you had infinite cores. That’s not even getting into linking, which is also usually at least partially if not totally a serial process. See also https://en.m.wikipedia.org/wiki/Amdahl%27s_law
sgerenser··on All clickwheel iPod games have now been preserved for posterity
on macOS you can still manage/sync iPods from the Finder (it was moved to there from iTunes when they killed iTunes).
sgerenser··on US economy added just 22,000 jobs in August, unemployment highest in 4 yrs
That thing about gig economy jobs being counted as "7 jobs" because "it's a company and on average companies employ ~7 people" sounds like complete BS. I can't find anything anywhere that mentions that, and it seems obvious that this is not the case: the BLS reports actual jobs, not "well this is a company, I don't know how many people they employ, but probably about 7?" Extraordinary claims requite extraordinary evidence.

Well, apparently the market disagrees. Futures are now pointing to a 100% chance of at least a 25 basis point cut at the next meeting, and the chance of a 50 basis point cut went from 0 to 11.6%: https://www.cmegroup.com/markets/interest-rates/cme-fedwatch...
sgerenser··on The Therac-25 Incident (2021)
Completely safe as long as the block of metal was in place. So you couldn’t just prevent the machine from putting out that much energy, you had to prevent it from doing that without the block in place.

Air France 447: https://en.m.wikipedia.org/wiki/Air_France_Flight_447

Inputs were averaged, but supposedly there’s at least a warning: Confused, Bonin exclaimed, "I don't have control of the airplane any more now", and two seconds later, "I don't have control of the airplane at all!"[42] Robert responded to this by saying, "controls to the left", and took over control of the aircraft.[84][44] He pushed his side-stick forward to lower the nose and recover from the stall; however, Bonin was still pulling his side-stick back. The inputs cancelled each other out and triggered an audible "dual input" warning.

sgerenser··on US Intel
I think this is more of an Intel problem than a general semi industry problem. I work for Arm and I’m compensated better than when I worked at Microsoft (although it’s partly due to stock appreciation after the IPO). But I’ve also heard that Broadcom has top-teir RSU grants as well, and even AMD is more competitive than Intel.
sgerenser··on Ask HN: Why hasn't x86 caught up with Apple M series?
The thing about Apple having a “special license” due to being a partial founder of Arm is an urban legend. They have an architectural license, just like several other companies making custom Arm CPUs do.
sgerenser··on AOL to discontinue dial-up internet
Apparently this is still happening (although I imagine their customer base is rapidly dwindling): https://en.m.wikipedia.org/wiki/QLT_Consumer_Lease_Services
sgerenser··on A message from Intel CEO Lip-Bu Tan to all company employees
Nope they’re en dashes. Minus signs aren’t longer than en dashes anyway.
sgerenser··on Job-seekers are dodging AI interviewers
I didn’t think Canonical did IQ tests, they just wanted you to report your high school GPA and class rank, and list all the clubs, activities, and awards and great things you did in high school and college. Even if you’ve been in industry for 20+ years.
sgerenser··on Job-seekers are dodging AI interviewers
Unfortunately, most people’s GitHub accounts are just a smattering of forked repos with maybe one or two (or no) commits done by them. Unless you look closely, it would be easy to be fooled by the average candidates github that is essentially meaningless.
sgerenser··on Live coding interviews measure stress, not coding skills
I think this wouldn't even be that bad of a thing (assuming that there's just so many candidates that you need some kind of filter), if it weren't for the issue pointed out in the study cited by the article: "But here’s a surprising finding: not a single woman in the public setting passed, while every woman in the private setting did."

That to me implies this isn't just an imperfect filter, but actually a very biased filter.

Wait, you don't build bridges in your spare time? You don't even have anything on BridgeHub? Immediate reject.
sgerenser··on MacBook Pro Insomnia
A dummy plug isn't just the end cut off of an HDMI cable, it actually simulates a monitor with EDID.
sgerenser··on Figma stock soars 230% in first day of trading, valuing company north of $40B
But is penpot worth $40B USD?
sgerenser··on Windsurf employee #2: I was given a payout of only 1% what my shares where worth
And here I thought I had it bad when houses went from 400k to 800k for the same house pre- vs post-pandemic in Raleigh, NC.
sgerenser··on Intel CEO Letter to Employees
They’re not hoping anymore. They already got acquired by SoftBank (well technically the deal hasn’t closed yet but I don’t think anyone doubts it’ll close.)
sgerenser··on Intel's retreat is unlike anything it's done before in Oregon
Interesting, is this specifically on the fab side? I work at Arm and the engineers working on design and validation are paid quite well. Not quite as well as NVidia but most non-juniors are well above the $180k mark quoted above for Intel.
sgerenser··on Intel's retreat is unlike anything it's done before in Oregon
Yes, that’s exactly what they did under Gelsinger: https://www.oregonlive.com/silicon-forest/2023/02/intel-slas...
sgerenser··on GLP-1s are breaking life insurance
Most likely, if you’re in a medium to large company (not sure the cutoff, probably somewhere around 500-1000 employees). Smaller companies will generally actually need the insurance company to be the payer as well since otherwise one or two huge payouts could bankrupt them.
sgerenser··on A.I. Is Making Sure You Pay for That Ding on Your Rental Car
I don’t think they even know what a reservation is!
sgerenser··on Preliminary report into Air India crash released
Extremely unlikely, since we can hear the other pilot ask why he turned the fuel switches. If it was an electrical glitch, he wouldn’t be able to see that they are in the cutoff position.
sgerenser··on Would You Like an IDOR With That? Leaking 64m McDonald's Job Applications
What about working as a SWE at Google? Apparently they recently implemented a personality test as an initial screener (they call it a Googleyness test).
sgerenser··on Some bits on malloc(0) in C being allowed to return NULL
Yeah, exactly, that’s my point. How many programs have memory leaks limited to (or even just materially affected by) 0-sized allocations? I’d have to imagine its a very small minority.
sgerenser··on -2000 Lines of code (2004)
Doing regex in C back in the day was not very common and far from idiomatic, unlike perl where its basically expected that you cram regexes in anywhere you can.
sgerenser··on Some bits on malloc(0) in C being allowed to return NULL
I might be missing something, but how does this help in checking for leaks? I mean, I guess you could use it to check for leaks specifically of 0-sized allocations, but wouldn’t it be better just to return NULL and guarantee that 0-sized allocations never use any memory at all?
sgerenser··on Finding a 27-year-old easter egg in the Power Mac G3 ROM
People hear services and think of Apple Music, Apple TV, etc., but the reality is $20B/yr of that “services” revenue is just Google paying Apple to be the default search engine.
sgerenser··on Skip the exit interview when you leave your job
OTOH, if things were really bad, and you want to a chance to actually effect some change, write up a public blog post about it: https://www.susanjfowler.com/blog/2017/2/19/reflecting-on-on...
sgerenser··on Why JPEGs still rule the web (2024)
Apple M3 and newer CPUs and A17Pro and newer mobile CPUs also have hardware AV1 decode.
