jetrink··on GitHub Copilot loses an average of $20 per user per month
Also, that is assuming that the group willing to pay $60/month includes many who use the service less than average. It's possible that only heavy users would stick around after a 6x price increase.
jetrink··on Oldest footprints in North America push back human arrival
Several dogs are credited with finding dinosaur fossils, but I will grant you that they were not allowed to perform the excavation.
jetrink··on Microsoft introduces AI meddling to your files with Copilot in OneDrive
I recently hit ctrl-z in explorer after accidentally moving some files and instead of moving back, they just disappeared. I couldn't believe it. I had to recover them from a remote backup.
jetrink··on "You have a 27% 'AI' issue in here"
I bet students would start to print out the plagiarized essays and retype them. If the plagiarists made an effort to make minor changes and rearrange things as they went, no screen recorder or edit history could distinguish it from normal essay writing.

Also getting everyone smiling with their eyes open at the same time. Phone cameras could record a group photo for five or ten seconds and use the best expression from different times for each person.
jetrink··on Open Air Schools of the 1900s
Yes, a school near my parents' house in Michigan did this! They built several large outdoor pavilions and also have a clearing in the adjoining woods that they hold classes in. I visited in the dead of winter and sure enough, there were about 100 kids out in the freezing cold all day long. Even from a distance, you could see that they were bundled up in multiple layers to keep warm. I was back recently and they still do outdoor classes, but I think it is only for a portion of the day now as I didn't see nearly as many students outside at a time.

jetrink··on Stolen van Gogh painting returned in an IKEA bag
Also dogs! New York banned dogs on the subway unless they fit in a bag or other container, so New Yorkers have been dressing their dogs in Ikea bags with four holes cut in the bottom.

jetrink··on “Make” as a static site generator (2022)
I regularly see people on HN who have a static site for their personal site or blog. There's a niche for this kind of thing.
jetrink··on Britain’s failed experiment in boosting low-wage sectors
I have the most recent version (116.0.3) and I'm also seeing a loop. This includes trying the site without plugins.
jetrink··on Hydraulic Steering – Principles of Operation (1956) [video]
My favorite old explainer video, telephone switching (1951): https://youtu.be/xZePwin92cI

About the Strowager Switch, which was invented by an undertaker who was fed up with the local telephone operators whom he suspected of diverting phone calls to his competitor.

jetrink··on Waymo puts the brakes on self-driving trucks program
You don't need a huge truck to move pallets. A standard Sprinter van can carry three or four and you can get specialized vans that carry six.
jetrink··on Waymo puts the brakes on self-driving trucks program
I question the premise that 18 wheelers should be allowed operate in urban centers at all, let alone be tacitly allowed to resort to illegal maneuvers. It's a convenience and cost-savings for businesses that are able to have a semi truck drive direct to their door, but it creates serious negative externalities for everyone else. The vast majority of cargo headed into the city should be shifted into vans or small trucks that are intended to drive on city streets.
jetrink··on The economics of the Birkin bag (2016)
> Giffen goods are essential goods, such as rice, potatoes and wheat. Demand stays high when prices increase because there is no ready substitute for them.

The way Giffen goods were explained to me is that not only is there no substitute for a Giffen good, it is the substitute. Imagine you eat meat and potatoes and the price of potatoes increases. If you can no longer afford your regular diet and need to cut costs, well, meat is probably still more expensive than potatoes, so you buy less meat and even more potatoes.

jetrink··on Mac shipments grow 10%, as all major PC brands see downturns
Anecdotally, even the non-technical people in my life are starting to notice the decline of Windows after updating to Windows 11. My aunt, for example, has been a Windows user since her first computer in the 1990s and she recently told me that while she dreads learning a new operating system, she's planning to get a MacBook when it's time for a new laptop. I'm also a lifelong Windows user, but I told her that it was a good decision. I don't see a future for Windows.
jetrink··on GPT-4 details leaked?
At a certain point though, models become good enough for particular tasks. Once that happens for whatever my application is, I don't care if OpenAI has a model that's twice as good on some metric, because it's overkill for my use-case. I'm going to be happy using a smaller, cheaper model from a competitor.
jetrink··on Humane unveils AI Pin – a contextual computer with a mini projector
Hosting an infomercial for a product that no one has had the opportunity to review must be a new low for TED.
jetrink··on Tokyo’s trash-collecting samurai takes a fun approach to cleanup
Last year I moved onto a street that had a ton of litter. I lived with it for about a month before I realized how easy it would be to walk a loop and pick it all up. For the first six weeks or so, I would fill two 20L garbage bags and by the next weekend, there would be another 40L of garbage waiting for me. Then something great happened: the amount of litter began decreasing. Soon I only needed to take one bag with me and recently I've been coming home with it only half full. Keeping the street clean has actually led to fewer people littering in the first place. It's a really great feeling to see such an improvement for so little effort and I would encourage anyone who enjoys walking outside to give it a try.
jetrink··on Controlled burns can prevent wildfires; regulations make them nearly impossible
I have another specific example of this to offer: Active vs. passive flood control. One passive control mechanism is the retention basin. This is just a pond connected to a water system. When it rains and the water begins to rise, some water flows into the pond instead of flowing downstream, reducing the effect of the storm.

You can improve the retention basin by adding a pump to actively manage the basin's capacity. When there is rain in the forecast, you pump water out of the basin, reducing its water level. When the rain arrives, you turn off the pump and let the basin refill. This increases the amount of water that the basin is able to divert during the storm.

I worked with a company that designed such a system and we even installed a demonstration unit for a municipality. It worked as intended and the city engineer advocated for expanding the project to all suitable basins. However, when the municipality's lawyers looked at the project, they argued that if the system failed to activate prior to a storm, the city might be liable any flooding that occurred afterward. Of course, the scenario where the system failed to function was identical to one in which it had never been built in the first place*, but that was not a convincing argument and the project was killed.

jetrink··on AI song featuring fake Drake and Weeknd vocals pulled from streaming services
The podcast Switched on Pop had a fascinating episode[1] last year called 'Invasion of the Vibe Snatchers.' They cite a number of instances where people are assigned songwriting credits on tracks simply because the new song is heavily inspired by an existing song or body of work. To be clear, the new songs are not covers, they don't contain any samples and there's no concrete element of the song that you can point to as being copied. However, taken as a whole, it's clear that the new song is similar to the old one.

I bring this up, because it seems to me that if we live in a legal environment where a song's "vibe" is now de facto copyrightable, there is no way anyone will get away with cloning someone's voice (outside of parody.)

jetrink··on Show HN: Personalized book recommendations with Librarian AI
Similarly, the top two suggestions for me were both sequels to books that I had selected.

Interestingly, I asked ChatGPT for recommendations based on the same list and it gave me a very similar result, including matching the top two suggestions! Coincidence? (I added a note that I was interested in finding new authors and it gave me a much better list.)

It also seems like it would come to light as soon as one of the trucks was involved in an accident. Checking the logs against who was operating the vehicle has to be one of the first things done during an investigation, if not by the regulator then by one of the involved insurance companies.
jetrink··on March 20 ChatGPT outage: Here’s what happened
The explanation at the time was that unavailable chat data (due to, e.g. high load) resulted in a null input sometimes being presented to the chat summary system, which in turn caused the system to hallucinate believable chat titles. It's possible that they misdiagnosed the issue or that both bugs were present and they caught the benign one before the serious one.
jetrink··on ChatGPT is rendering other people's chat history in the sidebar
I'm surprised we're making this mistake again. Isn't it possible to structure the chats as something more than a flat stream of text and insert unrepresentable tokens after the tokenization step?
jetrink··on Room-temperature superconductor discovery meets with resistance
Wolfram Alpha tells me that to bring 10 sq. cm of the material to 1GPa would require 18x the bite force of a T-Rex. I don't consider the inside of a dinosaur's mouth "room pressure" either, but I could imagine a reasonably-sized housing capable of producing that force.

Another comparison for scale: It is 1/6th the pressure at which artificial diamonds are manufactured.

jetrink··on Electro Gyro-Cator
Another early inertial navigation system for cars was the Etak Navigator, which was originally released in 1985. The idea for the device was conceived onboard Nolan Bushnell's racing yacht in a conversation between Nolan and his navigator, Stan Honey. Stan, who was also an accomplished engineer, went on to found Etak with Nolan's financial backing. You can see the device in Chevy Chase's car early on in the 1991 film Nothing But Trouble.

> I found it was often wrong, left out important details, and was superficial to the point of barely expressing an idea.

Sounds like it would be ideal for use in science journalism.

jetrink··on Ask HN: Those making $0/month or less on side projects – Show and tell
YNAB is $100/year and though it is polished and well-designed, it's a pretty simple system that hasn't changed much recently. I think there's a lot of room to compete on price, particularly for users like me who still enter all of their transactions manually.
jetrink··on Macroeconomic changes have made it impossible for me to want to pay you
Here's a fun list of these from Mike Pope from 2012:

He adds,

> Then there is the question of what we might call a nickname like this. A name based on a place is a toponym. A name for people from a city or region is a demonym. I solicited some ideas for this, too. We threw around corporanym and employeeonym. Someone suggested "idionym, which should mean roughly 'your own name'."

> The most interesting suggestion was from Colleague Clay, who knows his way around a number of languages. He suggested ergazomenonym ("from modern Greek εργαζόμενου= employee"). I like it tons, although I'd need some coaching, perhaps, in how to pronounce it properly.

jetrink··on We could stumble into AI catastrophe
I gave ChatGPT a section of the article and asked it for some non-clickbait titles and it suggested,

* Exploring the potential risks associated with advanced AI development

* Considering the risks of a world with transformative AI

Then I asked it to go the other direction:

* You won't believe what could happen if AI takes over: A world ending catastrophe is closer than you think!

I believe HN automatically removes 'how' from the start of titles on submission.
