It’s a strong assumption that humans are more rational than machines. Certainly typical customer service reps get bamboozled frequently, such as with SIM-swap scams. Even supposedly highly rational professionals like judges are often wrong.

I trust that the Apple benchmarks include all such effects. I'm less convinced that the RISC-V "projections" include them. SPECint2006 is supposed to be measured with real memory and an OS. Per-GHz numbers can't accurate

The acquisition was announced 18 months ago and the regulators have only just announced that there's a problem. That's about how long it takes to make a decision like this. If FB wanted to use Giphy to squash an upstart competitor

Most game logic has the luxury of being re-run every frame. That makes it a lot simpler than having to register events and callbacks and keep track of them or cancel them if something changes. Sometimes I use that style in server code and i

What has been preventing this happening in legal states already? Green bars and restaurants exist, but are a tiny segment of the market. I suspect it's that alcohol and socialization go well together, while cannabis doesn't so it&

Are meta-analyses that just average all the results from all the studies less reliable than picking a paper at random? I'd expect that to be the case if the bogus studies report the most dramatic results. A single bogus study out of 10

The book's thesis doesn't depend on the exact number of bullshit jobs. Any of the percentages correspond to millions of people spending their days doing work they consider useless. That must have an impact on society -- surely tha

Every company has dysfunction. You can see it as a curse or an opportunity. To take advantage of the opportunity, go to management with a description of what's wrong and a proposal to fix it, including the role or title you need to get

DRAM cells also decay over time (~ 60 milliseconds), but memory controllers have some logic to refresh every row on a regular schedule so it's not an issue. They should also have logic to refresh adjacent rows if some number of consecu

While the losses aren't too big, transmission lines are very expensive and take many years of planning to get the land rights required if there isn't already a transmission line going there. There aren't currently a lot of li

Google is big on solar power for its data centers, despite being intermittent. https://www.zdnet.com/article/google-1-6-million-solar-panel... They also have grid connections, of course, so it's no problem if the

Eventually a power source can power anything, but choosing good first customers is important. Usually, v1 of the product is expensive and flaky. So you need first customers who are willing to pay extra for the privilege of being early adopt

Although they have a BSL-4 facility, the WIV lab was also doing bat coronavirus research in their BSL-2 and BSL-3 facilities through 2019 [0]. The odds of leaks from those facilities are not as low. [0] https://en.wikipedia.org&#

How about interrupting at the same rate as a typical day in the office? That way the candidate can decide whether they really want to work there, and the interviewer can evaluate them under realistic working conditions.

I'm not claiming life must be common. The strong anthropic theory explains why we can be having this conversation despite the probability of life emerging being arbitrarily low, so there's no reason to assume the probability of li

The evidence for small replicators is that we now have large replicators. Whatever the absolute probabilities are, the relative probability of spontaneous emergence of small replicators is much, much larger than large replicators. Therefore

Indeed, optimization problems aren't all that exciting because there are usually efficient heuristics that get you 99% of the way there. A useful NP problem is generating code to meet some requirements. Instead of programming, you can

Regulation tends to protect incumbents everywhere. Whether or not you consider that bad depends on how much you value progress over stability. Stability often seems fine for the first decade or too, until one day you pause to wonder why you

The outburst insight here seems promising. Gen-X people want real-world activities to do with their millennial relatives that are engaging to both. I'm in that situation myself. I struggle with arranging such activities, and I'd b

1 MJ per second is 1 MW, a power level typical of portable diesel generators. Conventional nuclear plants are hundreds of megawatts each. Apparently it is quite hard to repeat the laser blast quickly, because the optical system heats up dur

Are you suggesting that driving around with 2 cars, one towing the other, will double the range? Moving 2 cars together takes almost double the power. The aerodynamic drag can decrease slightly — work on semi trucks in close convoy formatio

Yikes, what's my thesis from 1998 doing on HN? AMA, I guess. The idea was to make performance be a smooth function of policy parameters by adding randomization. In many systems it's a jagged function and hard to optimize. For exam

Having to verbally specify your destination address was always a lousy UX. Uber's UX where you enter it in an app is much better and allows using your address book, upcoming calendar entry, or searching by name.

Do you have any screen shots from the first version you put in front of customers? It'd be fun to see how far it's come. I assume investment banks were trying to convince you to do a traditional IPO instead of a direct listing, so

If the train had a loudspeaker on the front emitting a pure sinewave of known frequency, louder than anything else in the environment, you could probably just use a frequency counter and the Doppler formula. Given just some microphones pick

No, you can't trust NIST on security. They've certified algorithms they must have known were deliberately weakened in every generation: DES in the 1970s, the Clipper chip in the 80s, "export-grade" RSA in the 90s, and br
