rdtsc··on Japan moves to tighten rules for foreigners
> Japan can maybe afford to be cruel because their cultural exports keep the top of their “talent attraction” funnel large

I am fascinated by others being fascinated with Japan (meta fascination?). It’s like this mythical land of milk and honey for some. I don’t get? It’s just another country amongst hundred others.

rdtsc··on Japan moves to tighten rules for foreigners
> I don’t support xenophobia […] I came away with more empathy for Japanese xenophobic sentiment

What more does supporting it entail than being sympathetic to the sentiment? You’re not Japanese, it sounds like, so being xenophobic towards non-Japanese doesn’t work in this context. Only a Japanese person could experience it.

Would it also be xenophobia, or more xenoannoyance? Are the Japanese really terrified of foreigners or just annoyed at misbehavior?

rdtsc··on The Copilot+ PC brand is dead
> the purpose for Copilot+ PCs was to be able to deliver [NPU] experiences

Maybe for developers. Not sure ordinary consumers looking for a new tablet or laptop will be asking for “NPU experiences”

rdtsc··on Ask HN: Who's still keeping a DOS machine up because the business depends on it?
Often people confuse latency vs throughput/bandwidth. With streaming and batching USB4 will shuffle a lot data through on average per second. But it will never hit reliable microsecond level or even submicrosecond latencies.

At the same time ISA card will never reach 40Gbps throughout with CPU clocking at tens of MHz only or often less.

rdtsc··on Classified estimates show the NSA is paying billions to test AI models

rdtsc··on Classified estimates show the NSA is paying billions to test AI models
I guess I would be more surprised if the headline said "turns out NSA dropped the ball on AI and haven't even fired up a single LLM instance yet".

It's mostly about "testing" and "billions". But I am sure "testing" here is in quotes just like I wrote it. They are not going to get an itemized list unless it's coming from Snowden 2.0

- We "tested AI" on this Russian nuclear silo command and control center. It worked out pretty ok.

rdtsc··on Back and shoulder surgery is often worse than useless
Yeah is it legal to finance MRI machines as a business then and sell fast imaging? If it’s that bad near a big city could have a batch running constantly. Of course until the government healthcare system finds a bunch of money in a suitcase somewhere and decides to finally buy more machines, which would kill this business.
rdtsc··on Back and shoulder surgery is often worse than useless
> MRI's are expensive and difficult to amortize for poorer countries or ones that don't have a great healthcare system

Canada is towards the bottom. I see what you did there. I guess I never considered Canada a poor country or one with a bad healthcare system. But at the same time I was only there a few times to a major city and never interacted with their healthcare system.

rdtsc··on Porsche puts wireless EV charging into production
Heh. I didn't mean it in a gruesome way :-) just saw that someone mentioned it has a sensor to shut it off. So assuming it works as designed a cat might like the nice warm pad to hang out on in the winter. Owner parks hoping to charge their car by morning, the pad charges for 10 min, stray cat notices car is back and hides in there for warmth, charger stop charging immediately, cat moves on, and next day the car is not charged and the owner can't leave for work. It's just not a failure mode a cable has to worry about.
rdtsc··on Montreal adopts bylaw banning insults against police, municipal employees
> For example, when going through airport security in the UK and US you will see signs warning that insulting security officers is a criminal offense

I had never seen one in US. How is it framed, specifically "insulting", or framed as "non-compliant" or some other way?

rdtsc··on Porsche puts wireless EV charging into production
Well at least doesn’t have to worry about “suspension does not lower” and “charger covered in dirt “ or “cat hides under there for warmth” problems. Those are on top of the existing charging losses.
rdtsc··on Delta: Highly available, strongly consistent storage using chain replication (2022)
> We built out a control plane service (CPS) responsible for automating Delta’s fleet management. Each instance of the CPS gets configured to monitor a list of Delta buckets. Its primary function includes repairing

How does the configuration spread consistently across the nodes? How does each node know if each link to the next node is still the most up-to-date, based on the configuration system. This part usually is waved away but it’s one of the trickier bits. Usually there is some paxos/raft/zookeeper system involved here.

rdtsc··on US criticises Australia's proposed algorithm opt-out laws as 'censorship'
Thanks. Reading it at first seemed like “the people” here is you know, end users, people toggle some settings on their devices, not a government employee deciding. It turns out a government employee doing it. Yeah, just because US government is goofy doesn’t somehow make others sane or good.
rdtsc··on 'We hacked the FBI:' Hackers say they have data on all FBI employees
Yup, stealing from the FBI is pretty bold, probably a state sponsored group. Or script kids who got lucky up to that point.
rdtsc··on 'We hacked the FBI:' Hackers say they have data on all FBI employees
The worst? 100 FBI agents to do the chicken dance in DC for 30 minutes and then the database is sold to the Chinese
rdtsc··on 'We hacked the FBI:' Hackers say they have data on all FBI employees
> When asked if ShinyHunters was going to attempt to extort the FBI, the representative said, “what we plan to do is not something I’d call extortion, maybe coercion... This is not financially motivated,” they added

They should try something like "100 agents at noon on Sep 23 do the chicken dance for 30 min in the middle of the street in DC, then we'll consider not releasing the info and not sell it to the Chinese".

rdtsc··on Btrfs/ZFS/bcachefs under workloads classic benchmarks skip
> So use Ubuntu.

I am using Ubuntu!

> Why do you care if other distros consider it too risky given different business positions/models?

I don't know. Why do people comment on HN? :shrug:? It's fun and interesting to have a conversion?

I was mainly responding to a GP post that said "zfs is shunned. can't really get around that copyright issue". It didn't have a subject in there. As in "I can't really get around" or "anyone can't get around". And I read it as the second version and pointed that at least one distro did get around it.

rdtsc··on The Millennium Problems for Biology
Yeah that's the one. Just looked it up it was it the early 1950s. I guess I was either too impressionable or the textbook and/or teacher cut a few corners because I remember it being presented as "we solved the origins of life already" situation.
rdtsc··on The Millennium Problems for Biology
> Demonstrate the emergence of life from chemical precursors in a laboratory setting

Wait, isn’t this an already solved problem? I remember in the 90s school books (material written in the 80s-70s likely) it was presented as “so and so did electric discharges in an atmospheric gas mixtures and they got organic molecules” therefore the origins of life is solved. I remember thinking how cool that was. I guess the “therefore” step was sort of a lie if it’s still an open problem…

Nevertheless, Ubuntu is one the most popular linux distributions. So “can’t be done” is obviously not true since it has been done.

One can say it is “dangerous” and they haven’t been sued “yet” but the deed is done already.

rdtsc··on Btrfs/ZFS/bcachefs under workloads classic benchmarks skip
> zfs is shunned. can't really get around that copyright issue

Well except for Ubuntu, one of the most popular Linux distros supporting it.

rdtsc··on The American Religion of Self-Storage Facilities
That's the answer, it's a way to squat on land. Another way I know of is a golf course. It's more maintenance but it's a way to generate some cash to offset property taxes and then wait for a decade or two and sell.
rdtsc··on Gemini 3.8 Live and 3.8 Live Extended Thinking
I think it's good at basic coding and is cheaper and faster. Trying it vs Fable 5.1 I don't see it being even close capability-wise. What I mean by basic coding is "write a script to parse this data" and answering some questions based on the code. It does that well and answers fast. However, when it comes to planning and thinking through a more complicated design problem it's just not there yet.
rdtsc··on Gemini 3.8 Live and 3.8 Live Extended Thinking
> Ask yourself, how does Google -- a company that famously does everything -- benefit from SWEs outside of Google having access to powerful coding models? They would just be competition.

Bragging rights to say they have a SOTA model. I guess that was more like Google of 10 years ago with moonshot projects. Nowadays, yeah, perhaps if it's not helping sell ads, it doesn't make sense.

rdtsc··on Gemini 3.8 Live and 3.8 Live Extended Thinking
I was thinking about coding specifically. Also, see all these math and physics breakthroughs, it's usually not Gemini but Fable and Astra.
rdtsc··on Gemini 3.8 Live and 3.8 Live Extended Thinking
I wonder when/if we’ll see Gemini beating Fable and Astra. Last year I would have confidently bet Google will overtake the others just because they have the data, the hardware (TPUs) and a fat advertising money pipe and yet they are still behind. Anyone anonymous at Google want to hint when Gemini 4 will be out?
rdtsc··on I can't stop thinking about Papua New Guinea
You’d have to catch them first. If you watch the video there almost zero hand to hand combat. Their arrows don’t seem to have stabilizers either.

Obviously if this was filmed on video someone could have given one side a machine gun. Would’ve they used it or would have they still opted to maintain the tradition and fight the old way. The battle may have other reasons besides 100% dominating or wiping out the opponent.

rdtsc··on Nike exits the S&P 100 after 18 years and a $200B market-cap wipeout
> Wouldn't the fact that a Black man was their most popular face throughout their successful period negate the idea that it has anything to do with wokeness?

What does that have to do with wokeness? Sounds kind of racist to imply that.

rdtsc··on NTSB issues investigative update on B-767 runway excursion accident in Miami
Watched the video and one of the main set of wheels was off the ground a good amount time. Applying brakes then would have gone bad, they would have skidded sideways. They also landed almost flat, front wheel touched the ground almost the same time as one of the back set of wheels, that just looked ... bad.
