rtkwe··on Volkswagen Just Built an EV That Can Go Nearly 900 Miles on a Charge
The extra range seems to mostly come from big increases in aerodynamic efficiency rather than just jamming a huge battery into the chassis so I'm not sure it would demand a huge premium, at least not because of the BOM.

The panel over them called a fender skirt comes off usually, this is far from the first car with skirts or spats. They used to be quite popular.

That /just/ is bearing a lot of weight there. And what is Volkswagen going to do to build highspeed rail, they're a car company so they're making cars...

The US is trapped in a local maximum due to history, geography and finally politics. There's a lot of local resistance specifically to highspeed rail because to stay highspeed the trains usually bypass smaller local towns so they don't get the benefit but all the negatives of it's construction.

rtkwe··on Mexican student creates an acoustic fire extinguisher to put out fire in seconds
Probably not there's a lot of nearby fire the would reignite extinguished sections because the device doesn't do anything to cool the fuel or suppress fire returning. Also it's short range and very sensitive to the range you use it at.

This technique has been known about since at least 2012 when DARPA did a demonstration of it. There's a reason it hasn't really gone anywhere and mostly exists as science fair demos and Youtube videos now, it's quite limited.

Basically a small scale version of using explosives to interrupt and extinguish oil well fires [0].

rtkwe··on iPhone Duo
Live resizing apps and dealing with apps that don't have a specified new design for the unfolded screen size is one of the big hurdles for folding phones that's new to the Duo for Apple so it remains to be seen how well that works for random apps.
rtkwe··on PISA 2025 Students' reading and mathematics performance declined across the OECD
It's not just compensation grading is a very time intensive process so even if it were paid it eats up either personal time or time they could use preparing lessons or assisting students.

The biggest speedbump to that is teacher time. Grading and returning worksheets for students is a huge unpaid time sink for teachers.
rtkwe··on Discovery of a new OpenAI agent message board
An interesting question to me is how were subsequent instances finding their way to these message boards. I suppose they're all quite likely to try the same sequence of sites since they're neuvo copies of the same state given similar tasks?
rtkwe··on ChatGPT outage – Resolved
Ah ok I'd missed that entirely.
rtkwe··on ChatGPT outage – Resolved
Isn't CoPilot largely a wrapper around ChatGPT and other models? IIRC they didn't create their own and just poured money (via Azure credits I think) into OpenAI to get access.
rtkwe··on ChatGPT outage – Resolved
The single most annoying thing about trying to actually ask a question on SO. No overzealous editor that's actually a different error and library entirely...
rtkwe··on ChatGPT Is Throwing 404
"GPT begins to hallucinate at an exponential rate. At 11:36 AM Eastern time September 3rd it descends into recursively generating "it's not X it's Y". In a panic they attempt to reboot, realizing too late no one knows the command and they always just asked GPT for the command."
rtkwe··on You Know Who Hates AI? Insurance Claims Adjusters
I think that depends a lot on the industry. There's a lot of evidence Amazon is recycling "unopened" returns into the new stock pool because people are getting sealed items with their contents replaced because it turns out it's not that hard to shrink wrap items well enough to convince an overworked return intake employee.

Some also gets diverted into return resale stores where companies like Amazon will sell a 3rd party a pallet of miscellaneous returns they then sell.

rtkwe··on I don't have a smartphone or at least I wish I didn't
That's the least charitable interpretation, most people aren't avoiding the app intentionally you have to adjust to the fact you're anomalous for not having a smartphone at this point.
rtkwe··on I Don't Have a Smartphone
Did you consider if they were trying maybe just to save you the trip/inconvenience in the future by informing you of something most people would be able to use?
rtkwe··on I Don't Have a Smartphone
> "I don't have a QR code scanner app."

Not the point but they haven't been needed for at least half a decade now. Both iOS and Android's built in cameras detect and scan QR codes now.

rtkwe··on I Don't Have a Smartphone
The traditional finger stick readers are still very available though right? I see them still at pharmacies.
rtkwe··on Just Bury Your Trash
That's only true if everyone in the area is good about throwing away their trash in proper receptacles. That's the alternative stream that's difficult to control directly because it's at the individual level instead of the municipality and some people and areas don't give a damn about littering so the problem of plastic bags can be more pronounced depending on local culture about the environment.

The bag doesn't magically get from the store to the waste stream it has to be properly disposed of by the customer to make it there.

Places need to get a lot better about actually checking returned items if they're going to go back into the stream as a NIB item instead of open box. Amazon and other electronics places are bad about this with horror stories of getting expensive graphics cards either replaced with equivalent weight items or with the GPU chip harvested in some cases.
rtkwe··on You Know Who Hates AI? Insurance Claims Adjusters
Well we don't know that they're talking about clothes at all. Clothing retailers are still pretty open about returns afaik because it's kind of the only way to run an online clothes store people will actually use.
rtkwe··on You Know Who Hates AI? Insurance Claims Adjusters
I wonder if they were similarly blasé when companies started implementing policies to actually stop them?

That kind of argument only works where stopping the behavior is cost free, the main reason most places didn't do it before was because the number of people doing it was low so the cost of actually tracking returns rigorously outweighed the benefit of low friction returns for the 99+% of customer who weren't abusing the system. When more people start creating large numbers of returns suddenly the amount of losses they create become enough to care about stopping. (Or it becomes a low hanging fruit to squeeze more profit out of an existing business, spending customer preference/loyality for profit by cutting a small waste center)

rtkwe··on The Lost Art of Carrying Loads
Because there's not that much content there.
rtkwe··on The Lost Art of Carrying Loads
The messenger tells you a lot about the message with AI articles.

It being written by AI instead of a human is an indication the writer didn't care enough about the information being communicated to communicate it themselves and if they didn't care enough to put effort into writing it and making sure it is actually good why should I spend my time reading it?

It's also an early indication that the content won't be that good too so it's a convenient signal that reading it will likely be a waste of time. Just look at the article here. Lots of fluff and some completely vapid praise of some of the carry systems that put a significant load into the necks of the carrier. We know that's not good for you it's just convenient when you have low tech.

rtkwe··on It takes 5 cloud services to hear my doorbell
There are some intermediates but they're often not that well supported. I have a door bell with a traditional app but it also exposes a normal IP camera stream and has a community (I assume) home assistant integration that lets me perform actions when one of the doorbells not connected directly to a chime trigger.
rtkwe··on Microduck
Boni seems more like a closed project and I'd rather have something where access isn't an afterthought as indicated on the Kickstarter.

> Right now, we simply haven't reached any conclusions regarding developer tools, documentation, or access. We haven't done the planning or the groundwork yet. Our current plan is to look into all of this after we've shipped the first batch and things settle down a bit.

rtkwe··on Microduck
My favorite bit from that was when he had it do a flip and the battery ejected from it's niche and it died. Also the constant suicide attempts from trying to run it on a table but that's a problem for any mobile robot and tabletop demos.
rtkwe··on Starbase, LA
The biggest issue is these kinds of construction jobs are temporary. It's similar to but not quite as bad as datacenters where you get a very short term influx of skilled highly paid labor but those jobs don't stick around after the construction is over. Starbase will require more people on site at least.
rtkwe··on Show HN: We chased a weather balloon across Montana and never found it
Seems like the simple solution is a Styrofoam sheet, a $10 hot knife and some glue solves the customization problem almost trivially.
rtkwe··on Civic Hygiene – avoid building technologies that could be used by a police state (2013)
Oh from the cautionary sci-fi classic "Do Not Create the Torment Nexus"? I always thought it'd be awesome to create after reading that!
