Hims offered semaglutide for $99/month. That’s a 90% discount on unsubsidized consumer prices for injectable semaglutide. I also don’t see any evidence that they sold a placebo, but I’m just catching up now, perhaps I missed where they’re selling something with a different active ingredient which does not work.

I find it so frustrating that Lockdown Mode is so all-or-nothing.

I want some of the lockdown stuff (No facetime and message attachments from strangers, no link previews, no device connections), but like half of the other ones I don't want.

Why can't I just toggle an iMessage setting for "no link preview, no attachments", or a general setting for "no automatic device connection to untrusted computers while locked"? Why can't I turn off "random dickpicks from strangers on iMessage" without also turning off my browser's javascript JIT and a bunch of other random crap?

Sure, leave the "Lockdown mode" toggle so people who just want "give me all the security" can get it, but split out individual options too.

Just to go through the features I don't want:

* Lockdown Mode disables javascript JIT in the browser - I want fast javascript, I use some websites and apps that cannot function without it, and non-JIT js drains battery more

* Shared photo albums - I'm okay viewing shared photo albums from friends, but lockdown mode prevents you from even viewing them

* Configuration profiles - I need this to install custom fonts

Apple's refusal to split out more granular options here hurts my security.

The main point of lockdown mode is to provide security against state sponsored attacks against journalists. If it was granular the attackers would exploit whichever switches most people leave off. It would be a cat/mouse game until all the switches were turned on. So Apple skipped to the end of the game.

This is about "neuromorphic computing", a model invented in 1980's which colocates memory and computer, just like real brains. Plus about "memristor", a weird electronic part invented in 1970's. People have been doing research since then, and yet there is no progress.

This is yet another call-to-action, this time under "AI consumes too much energy" sauce. I've seen those for more than two decades, and it nothing ever came out of this.

A special mention for this paragraph:

> The programmability challenge is perhaps the most significant. The von Neumann architecture comes with 80 years of software development, debugging tools, programming languages, libraries, and frameworks. Every computer science student learns to program von Neumann machines. Neuromorphic chips and in-memory computing architectures lack this mature ecosystem.

This is total B.S, especially with application to AI - there is no need for "ecosystem" of millions of software libraries, there is a handful of algorithms that you need to run and that's it, the thing can earn money. And of course plenty of people work with FPGA's or custom logic which has nothing to do with von Neumann machines - and they get things done. If you have a new technology and you cannot build even a few sample apps on it... don't blame establishment, it just means that your technology does not work.

I think they have a point about merging the CPU & memory. It seems to have worked out well for Apple. Their proposal sounds like another step in the same direction.

Ah, so then the air temperature should reduce fuel consumption by 30%×30%=10%, which does seem to roughly match my experience. Thanks for pointing that out!

Internal combustion engines are actually more efficient in cold weather than hot weather. But the other factors like drag outweigh the increased efficiency of the engine. And since gas engines are so inefficient to begin with you don't notice much of a difference. https://physics.stackexchange.com/questions/270072/heated-an...

That’s like saying that the human brain is based on simple physical field equations, and therefore its behavior is easy to understand.

Right, which is the point: LLMs are much more like human coworkers than compilers in terms of how you interact with them. Nobody would say that there's no point to working with other people because you can't predict their behavior exactly.

Nobody would say:

"...there's no point to working with other people because you can't predict their behavior exactly."

Because you CAN predict coworker behavior to a useful point. Ex, they'll probably reply to that email on Monday. They'll probably show you a video that you find less amusing than they do.

With LLMs you can't be quite sure whether they will make something up, forget a key detail, hide a mistake that will obviously be found out when everything breaks, etc. Stupid things that most employable people wouldn't do, like building a car and forgetting the wheels.

>I googled PZEV, and apparently all it means is that it isn't releasing gasoline vapours - other emissions don't matter.

No.

PZEV means partial zero-emotions vehicle… it is just STAR-STOP.

When you stop, the car shuts off and when it’s off it isn’t emitting anything. That is what it means.

It’s a total scam. Subaru was the first to put a logo on a US government mandated requirement (that made no sense).

I don’t think that sounds right. My car was never offered with start/stop tech. Unless maybe they ask regardless of whether the car could even have that option… hmm.

Hilarious. If you picked a person at random off the street and gave them the job, what are the odds that they would have done this?

I feel like over 80% of people, if asked, "Is it okay to upload government documents to ChatGPT" would say, "Are you crazy?".

What I'm saying is that this is impressive levels of incompetence.

simulator5g · 15 days ago
Tbh I don’t think people outside the HN crowd would think it’s that crazy to use ChatGPT. It feels like the kind of thing everyone does regardless of the rules, like driving 10mph over the speed limit.

> These acronyms are a nightmare, what the hell is a PHEV? EREV? PZEV?

PHEV is the old term, it's a plug in hybrid EV. I.e., you can plug it in and use the battery, or use the ICE engine via petrol (gasoline).

(B)EVs are pure battery EVs. Think Tesla.

REEV/EREV is range extender EV. Essentially an EV that has a small ICE engine that's very handy for making the 50 or 100km battery "run" for 500km if the need arises, by using the ICE as a generator.

In some countries, you also have "strong" and "weak" hybrids - these are not cars you can plug in (they only take petrol), but they use some motors and battery to vastly improve the efficiency of the engine. Think doubling your mileage levels of good.

> Consumers are just expected to know this stuff somehow, it’s nuts.

Yeah no I don't think that's good design either. May I ask what kind of parts do you buy that makes it so confusing? Our car (Honda) has a very simple model name, there's not a lot of variations or options to confuse to begin with.

Btw, if you want a real fun doozy, look up the parallel series hybrid system that iirc GM had. It was a beautiful beast - it could basically take any power source, and do anything with it (charge battery, run wheels etc). There's a good YouTube video on it if you search for it.

Whenever I buy parts for my regular gas car the parts site asks if it’s PZEV or DOHC. To make matters worse the PZEV version is also DOHC (dual over head cams) as far as I can tell. And the VIN number doesn’t say if it’s PZEV or not. It’s not on any of the paperwork I got with the car either.

I think that's just sun+charging, not wireless charging specific.
simulator5g · 17 days ago
I switched to wired charging with the phone mounted in the same spot and the heat issue went away. Wireless charging produces a lot more heat than wired.
