rtkwe··on Solar power is becoming bigger than nuclear
That's also true, partially driven by a lot of hurdles and time spent fighting for approval due to the anti-nuclear push due to the things I mentioned, but it is also just expensive to build in the US because our labor and land is pretty expensive too.
rtkwe··on 'It's offensively cheap': Solar power is quietly becoming bigger than nuclear
Depends on many factors. If installers are able to fully fill their available time and crews with jobs at the current price and expanding is limited by the availability of new crews high prices could be a stable equilibrium until a) more crews become available/techniques improve to speed up install times or b) demand relaxes and they need to drop their price to find sufficient customers.

There's also other factors like the overall cost being beyond people's willingness to save for when financing is available or the extra value that financed installs can provide the underwriters when they're bundled and sold as a stable income stream like houses were in the mid 00s.

"If it can be done cheaper someone will" is based on a lot of simplifications and assumptions about the market in question.

rtkwe··on Solar power is becoming bigger than nuclear
Nuclear /could/ have solved this years ago but the spectacular and scary nature of failures like TMI or Chernobyl [0] really sunk any chance of that happening. Plus you had all the traditional nonrenewable energy providers intensely interested in stoking fears of that and the question of nuclear fuel storage.

[0] Yes pollution from normal everyday fossil fuel power generation causes more damage and deaths in the aggregate but it's a diffuse hard to attribute kind of damage which makes it far less, for lack of a better way to say it, real to people. eg: Did living downwind of that unupgraded coal plant really kill them or is their death because of something else.

rtkwe··on The Lucrative World of Literary Scams
A deep dive into a different literary world scam from Dan Olsen (aka Folding Ideas) covers the world of con artists pushing done for you audio books [0]. It's probably only accelerated since genAI and LLMs became accessible, now you don't even need to low ball audiobook talent to get it made now. I wonder how amazon has tried, if they have at all to avoid being flooded with spam.

rtkwe··on Tesla Roadster
The per 1k car figure makes it look like Waymo has 50% more cars or they're 50% more active than the Tesla robotaxis.

Not the base model, the base was supposed to be more generally available for regular rich people not just hypercar people.

It's unclear what they'll be classified as and probably comes down to some negotiation and lawyering to decide how restricted they are. You can sell a lot of restricted hardware to US citizens that you can't sell internationally due to ITAR.

CF can make a fine pressure vessel it's just difficult to build and they require constant inspection that OceanGate didn't perform (and ignored evidence from their own monitoring system that the PV was responding differently to pressure after a hard bang it suffered when docking in one of the last few dives). SpaceX already has experience building the COPVs that Tesla is probably using and knows their limits pretty well though I don't want to be standing near one in a major crash either.

People with lambo money generally also want a car that doesn't fall apart constantly AND rapidly lose its value.

But you'd expect if this were being treated as a likely success for Tesla the announcement would have caused a price bump or at least a reversal of the trend.

Also 2 years ago is a pretty specific time point where it was near the lowest it's been looking back a less random 5d, 1M, 6M, 1Y and 5Y it's only up on the 5Y chart and that's a relatively meager 25%.

rtkwe··on Delta’s Biscoff cookies were supposed to be temporary
I love boiled peanuts and I'm always tempted on roadtrips to grab some when I go through areas where they appear as gas station snacks. Usually that's when I'm down into South Carolina or farther south.

That's been pulled a number of times in the AI stocks and surrounding companies. MS invested in OpenAI mostly in the form of compute credits, etc.

Ah old Dilbert. Shame the author went crazy.
rtkwe··on New 'Super Ice' 10 Times Stronger, Bringing It Close to the Strength of Concrete
Yes the book itself is broken into 3 parts but if you're looking at it from a scientific plausibility scale parts 1 & 2 are in the same vicinity of that scale where part 3 jumps a good ways into more traditional scifi levels of plausibility.
rtkwe··on Delta’s Biscoff cookies were supposed to be temporary
I also suspect there's not much reason to boil peanuts in water outside of the very specific (and delicious) snack called boiled peanuts. I can't really think of any other dish that uses them as a normal ingredient. Most of the time you'd toast them in oil for dishes or use peanut oil afaik.
rtkwe··on Delta’s Biscoff cookies were supposed to be temporary
Yeah that's definitely the issue with the shellfish. I'm just more surprised the allergen is sufficiently different from the smell that they are disconnected in peanuts.
rtkwe··on Delta’s Biscoff cookies were supposed to be temporary
The American Academy of Allergy Asthma and Immunology disagrees, which I'm surprised by and totally thought they could too. Someone linked to this in another thread.

> What can occur is that the patient smells an allergen, and that smell triggers a strong memory of a past reaction or the fear of having a reaction and signs and symptoms of panic may occur – including an increase in heart rate, tight breathing, flushing of the skin and nervousness, all of which could be mistaken as signs and symptoms of anaphylaxis. ... While smells can linger in the air, the allergen proteins do not, which is why smelling a food will not trigger anaphylaxis.

Interestingly some allergens like those in shellfish /can/ aerosolize in a boiling pot, however according to them peanuts cannot. I can still absolutely see airlines reacting to passengers thinking they're having attacks and eliminating peanut snacks out of caution and to avoid the issues even an imagined attack can cause on a flight. That and the risk of surface contamination probably?

rtkwe··on I designed a nose guard for my dog and gave it away. Now 500 dogs wear one
AI didn't really help in making this at all just the article talking about it months later. They already did a write up on their own about a year back without clauding it up.
rtkwe··on I designed a nose guard for my dog and gave it away. Now 500 dogs wear one
That would have to be a lot more custom fitted to the dog. It's not the best but the neck attachment is a lot easier. Also it seems to work just fine from the large amount of users it's gotten too, I bet the distance doesn't actually change that much.

What's the big risk though? Plastic has pretty low conductivity so the surface in the sun might get a little warm but the whole thing will take a long time to heat up. Same thing keeps it from being very dangerous to touch, plastic transmits the heat it has to your hand more slowly too. Plus most dog noses are already black so you're not even really changing the absorption of the area much. If the nose can carry away the heat of the sun directly hitting the nose skin it can do the same for it creeping through the plastic nose guard too.

Lead isn't the reason they're generally not food safe, it's the additives they use to make the plastics more printable.

Why are you concerned about the food safety of this though?

rtkwe··on “Math 2.0” will need to value mathematical progress more holistically
In mathematics it's usually a large portion of the paper because they know it's the interesting and useful part of the discovery. Often they come up with new tools and techniques and those often unlock further discoveries.
rtkwe··on “Math 2.0” will need to value mathematical progress more holistically
The other gap in AI is it doesn't explain or lay out how it got to the final proof which is often more fruitful for new techniques etc than the final proof by itself.
rtkwe··on Visa, Mastercard, major banks facing new litigation over 'anticompetitive' fees
> The creepy thing is how that escrow built into credit cards is forced on every little transaction.

That's essentially what a CC company does though, every transaction they're briding the timing gap between the card holder paying the CC company and the CC company paying the business. That's the core value add and cost they're bearing that they charge for.

They have risks from both sides of the transaction; on the one hand scam merchants who might get chargebacks and on the other customers who never pay off their balances (thought I guess that risk is covered by their interest charges mostly).

rtkwe··on Cops Can Bypass iPhone's Automatic Reboot to Get into Locked Phones
That's too cute by half for the law, this kind of "I'm not touching you" argument comes up each time and it just doesn't work. The guy intentionally provided the code knowing it would destroy the "evidence"/contents of his phone if they entered it, it's clear what his intent was and the data would not have been destroyed if he did not take that action. The minor separation that he did not enter the code himself is highly unlikely to protect him in this case.

It's been a weakness in destructive duress codes since their inception.

rtkwe··on Cops Can Bypass iPhone's Automatic Reboot to Get into Locked Phones
That case has the specific, very important, wrinkle that he provided a _destructive_ duress code, he could have continued to refuse to provide the unlock code just fine legally. It's the use of the duress code that is likely going to be getting him in trouble and that falls outside of the existing defined protections about being compelled to unlock safes/computers etc containing possible evidence against yourself.

We'll have to see how that case goes but ultimately the reason he's getting in trouble is only tangentially related to his phone being encrypted. It's more correct to think of it like he smashed the phone to pieces (and imagine this definitively destroys the data for the sake of the metaphor) instead of it being about the encryption itself.

I doubt it, mostly because phones were a lot easier to crack back in those days already so I doubt a TLA needed to push for it to be removed.

The specific extra that grapheneOS adds is that you can have a required Fingerprint + PIN with a shorter easier to enter pin while also having a long first unlock passcode. Only a first unlock passcode then biometrics is not secure in the US if your device is in the AFU/biometric-only (after first unlock) state because you can be easily and legally compelled to provide a biometric unlock.

rtkwe··on Cops Can Bypass iPhone's Automatic Reboot to Get into Locked Phones
This seems specific to GrapheneOS (unique as far as I know though I'd be happy to learn otherwise) where you could set a very long first unlock passphrase and have a shorter less cumbersome fingerprint plus pin option for subsequent unlocks. I wouldn't want to have to enter a long passphrase every time I unlock but once a day isn't so bad.
