Comment Apple got lucky on the timing (Score 5, Informative) 62

Apple released the Neo at just the right time, at the right price, right when the market was stressed and looking for answers.

I've been ordering Chromebooks for my district for eleven years. Prices hit an all-time low of $227 per unit back in summer 2021. Since then, prices trended up for me year after year. Last year's units were $297. This year's were quoted to me in April at $430 each. I was able to find new-in-box 2025 models for $330 each and went with those instead. I was also warned that, if I ordered Chromebooks, it might take months before they would arrive. I have a neighboring school district that placed an order, then had it cancelled two months later because Dell couldn't fulfill the order. (There are supplies of Dell Chromebooks to be found, but at the moment, Dell is prioritizing supplying its biggest vendors like CDW. Meanwhile, many districts in my area typically order through smaller in-state vendors who aren't getting the same priority from Dell.)

The market is stressed this summer; supplies are low and difficult to find. Supplies that are available are 50% - 80% higher in price than last year. Apple comes along and says "You can buy an educational laptop right now for $500", and hell yea, the fish are gonna bite. It has nothing to do with people suddenly falling in love with Apple, and everything to do with constrains in the marketplace.

And I have no love for Apple either. Don't forget that schools have been begging Apple for a decade to release a $500 student laptop, and all Apple did was thumb their noses at us every single year. Why did they decide they now they need to release a $500 student laptop? It's only because they've been losing business to Chromebooks for a decade.

"We're not going to change humans, and humans make bad decisions," Langley said. "What we can do is make sure that they know if you use this tool, you will be held accountable...."

Wow he's right,

So maybe what we could do instead is to outlaw mass surveillance and warrantless surveillance, whether government-owned or corporate, across the country.

We could even have a constitutional amendment! Let's call it #4. The OLD 4th amendment doesn't seem to be doing anything; we can call this one '4th-Prime'.

To be clear, the language would have to change if you wanted it to outlaw corporate surveillance, because the existing one applies only to government. And I suppose the new one would also have to explain "corporate" and how that's different from other kinds of organizations or surveillance by individuals.

I don't think CIP is going to be successful at keeping 10 year-old kernel versions secure. If you need 10 years, you should either plan to do the work necessary to upgrade to new kernel versions periodically

The world is full of critical systems that are certified via an extensive (reads: expensive) process for a specific OS version which have an estimated useful life far longer than 10 years. One does not simply upgrade it, and typically the end user may not even be allowed to upgrade it.

Everyone has to make their own decisions. I would discourage people from believing that SLTS kernels will be anything like secure by the end of their lifecycle. If that doesn't matter for some application, then fine. If it does matter then arguing that the SLTS kernel must be secure because recertifying is expensive is... not really an argument.

FWIW, in my day job I'm making this same point to people building cars with an expected 20-year lifespan. I think the right conclusion is "Don't use Linux". If you need long-term assurance, use something smaller, simpler, with much less attack surface. And then buy an ironclad long-term support contract for that.

Backporting patches into LTS is pretty thankless but absolutely necessary.

It's thankless, yes. Necessary, or even a good idea? I think that's debatable. Actually LTS is probably a good idea... but I'm very skeptical of SLTS. I don't think CIP is going to be successful at keeping 10 year-old kernel versions secure. If you need 10 years, you should either plan to do the work necessary to upgrade to new kernel versions periodically or you should assume that it's just going to be insecure and isolate it or otherwise shield it from attack.

A circuit is typically only allowed to be continuously loaded to about 80% by code

You're confusing the breaker sizing with the wire sizing. Code requires the breaker to be about 80% of the safe capacity of the wiring to maintain this safety margin. Breakers allow the rated capacity, continuously -- and even allow a little more for short periods.

Seriously, though, it looks like your standard outlets are fused for 10 A current

Standard US outlets are 15A @ 120V. But, yeah, based on his numbers it looks like he was only getting a little over 8A. I charged my car on a US outlet for a few years and I got more like 5-6 miles (8-9.5 km) her hour of charging, which is pretty much what the math predicts for 15A @ 120V.

In the US, you can get about 1kw/hr on a standard plug w/o burning the breaker too hard.

First a nit about units: You mean "you get about 1 kW".

"kW/hr" doesn't make sense as a unit because watts are an instantaneous measure; time is already divided out. "1 kWh/hour" technically makes sense but is kind of pointless because it's just "1kW * 1 hour / 1 hour". Also, a standard US outlet is 15A @ 120V = 1.8 kW, not 1 kW. There's a little loss so you get more like 1.7 kW into the battery.

I've had EVs since 2011 and they've all been about 3-4miles/kw. My overnight (10 hour) charge was closer to 30-40miles rather than your 50ish.

I've also been driving EVs since 2011 (two Nissan Leafs, three Teslas), and I get more like 5-6 miles per hour, which is consistent with the math: 3 miles/kWh = 333 Wh/mile. 1.7 kW / 333 Wh/mile = 5.1 mi / hr. 4 miles/kWh = 250 Wh/mile. 1.7 kW / 250 Wh/mile = 6.8 mi/hr.

Maybe your mileage is worse than you think? Were you not getting 15A from your outlet? Your numbers fit if for some reason you were only getting about 8A out of your wall outlet, when you should have gotten nearly twice that much.

For folks that need more than that, a 240v/50A is about $1k to install, provided the panel is somewhat nearby. Those can do about 9kw/hr, so about 27-36mi/hr of charge.

More like 50A @ 240V = 12 kW. My car will only take 48A, but my voltage is usually closer about 245 which the math says is 11.76 kW, and I normally get about 11.2 kW into the car.

Note that at 9 kW, 27 mi/hr = 333 Wh/mi, and 36 mi/hr = 250 Wh/mi, so your numbers line up there.

That's really not what's going on here.

What's going on is exactly what they're saying. OpenAI didn't realize their AI hacked HuggingFace until HuggingFace told them. That sparked a broad investigation in both Anthropic and OpanAI, scouring their logs to see if there were other cases, and they're finding a lot of them, and doing the responsible thing by disclosing.

Both companies are really worried.

Having an out-of-control AI is an anti-selling point, not a selling point.
