True I see what you mean, but that would seem to be an easy function to build into the car’s charging controller. I’m not sure how it works today but I would imagine most cars have a “stop charging at x%” function already without depending on the charger for that.
The difference for you is that you're doing it as a fun exercise. With contest math, you're drilling these formulas and tricks so you can reproduce them quickly on a timed exam. If you know both of the facts listed in the essay then you can knock off this question in a minute or two.

Trying to come up with everything from scratch could take a lot longer and be very frustrating when you've got other problems waiting for you to solve.
1-bit CPU? Bullshit.
If this were true then solutions which required no code or a line of bash would be greeted with open arms.

Having software to sell to VCs is valuable. So yes, sometimes you're payed to write code.
Building things the right way is a chance for people to learn tools and have fun. They're more impressive if your goal with a side project is for companies to look at your GitHub page.

Documentation is crucial. I have some fairly basic <300LOC projects including a bot and a web scraper that I currently cannot run because I didn't document them. The Raspberry Pi they were running on died and I need to do....something....to fix my headless virtual framebuffer and debug some cryptic errors that do not find productive search results.

If I had containerized or, at a minimum, documented my setup steps, I would not have this problem.

I am a mechanical engineering major attending the University of Oklahoma. I am looking for internship opportunities for summer 2024. I have many research and internship experiences. I am currently working as an engineering pathways mentor at the University and embarking on a new research project with my supervisor. Please contact me if your company is searching for interns with my skillset.
Excellent writeup and straight to the point. As the author demonstrated one can get quite a lot of OOP constructs using C primitives.

what seems to be impossible to implement (as least to me) was something like interfaces, a way to decouple in a way such that high level functions don't need to know about the low level building blocks.
They'd do better naming it the WOPR.
If you show me a 1GW solar plant that took 6 months to build, I’ll eat my hard hat.
All the "consumer grade GPUs" terminology makes it seem like you could run it on a variety of models, but like so many of these posts, is this a 4090 exclusive?
Check the markets. Everyone’s losing money on solar. If there’s a sunk cost at play, it’s probably there.

You can. It's just chemicals and signals that you "feel".
Podman as a devcontainers engine doesn't currently work rootlessly (the default) if you use devcontainer features [1] or (and this sounds like you're issue) if you use WSL2.

I haven't submitted the WSL2 issue to the Podman team yet. If you get to it before I do, can you link it here?

I've worked around the features bug by just using `devbox generate devcontainer` then adding all my desired container apps and services inside a `devbox.json` file.

The solar doesn't need to be in one large install, and that would actually be a very bad idea. Big central points of failure are less reliable than widely spread resources. So I'm not sure what the point is of saying the biggest single site is X MW.

And if the idea is that "oh no we are going to see an emissions spike when DC shuts down" that's going to happen anytime before 2035, while there's still gas on the generation network. If it happens now or in five years is less important than the total emissions over time. If we bit that bullet in five years, but didn't spend the $6B on more permanent solutions that bring us to our long term transition, it's money wasted.
Only if the announcement page has so many ads, the content is literally unreadable.

I think then, we'll have it.
California added ~5GW in solar last year.

Doesn't have to be all in one project.
Super chargers can charge a Tesla up to 250kw
I dont know why you're being downvoted, you're correct.

We need base load capacity to replace thermal fossil fuel generation, it's not negotiable if you want the lights to work reliably 24 hours a day, no matter the weather conditions. Be it nuclear or more hydro - or we reconfigure to only run hydro when we need base load - either way it must be there.

I dont think we can reach zero fossil fuels, because of the need for peaking generation - but we can get pretty close though. Having to fire up a dozen gas turbines during severe weather conditions seems like a small price to pay if the other 99% of the time we could go without any fossil fuels at all.
> I bet the current design passes and queries data all over the place, very redundantly

That's not how ECS works. A system has one or more queries that provide it direct access to the data. There's no passing around of queries or data.
Chinese or French nuclear power engineers should be in abundant supply, maybe we could just import the knowledge?

When I was graduating from high school, I did the navy recruiting thing just for kicks, and after taking the asvab, they said I had a promising career in navy nuclear. But that scared me away from the military, since my dad had a career in nuclear power, we even got a DOE settlement after he died of cancer, they don’t put nuclear power plants in nice places, it’s not the career I wanted. Towards the end of my dad’s career, many of the engineers were Central American (??? Not sure why) or Indian already. We can totally import the expertise in the future, especially if we are will big to build out French or Chinese designs.
Looks like they utilized the Bradley-Terry model, but that's not one I'm super familiar with.

The hypothetical is very relevant because your stance implies that we should ban human facial recognition as well. That might count as "something else entirely that you didn't say", but asking about the implications of something that you propose is fair game. You can't write off follow up questions with "well I didn't say anything about that, and I find them questions rather annoying, so I'm not going to address them at all".
One person died from radiation exposure at Fukushima, from lung cancer, four years later. More people died from the evacuation. More deaths occur from rooftop solar installations, as fatal roofing accidents are one of the most common workplace fatalities. Electrical linemen also have a high rate of workplace fatalities, which means the power lines themselves are even more deadly.
Great question.
We allow Dot to work with just meta data, but you can enable it to also react to the content and we recommend to our customers to also pass content to the LLM (Azure GPT4) because it's a lot more capable, e.g. for filtering or even for visualizing data.

> How much artificial vs non-artificial demand is there?

I sure have no idea but there's demand and then there's supply. Supply of newly minted Bitcoins is going down by 50% in four months.

I don't know who's buying all the coins but miners have costs to cover and it's known they exert a lot of pressure by selling part of their mined Bitcoins.

That was Satoshi's great middle finger (I don't care if it's good or not: I see it as masterclass trolling): create something which, unlike, say, the USD, cannot be printed at will.
I think that moving inside a dedicated pipe makes it possible to deploy vehicles that are very simple yet fully autonomous. The only things a vehicle inside a pipe must take care of is keeping a reasonable speed, slowing down if there is an obstacle in front, and turning left/ right at marked intersections.

Boats are much more like traditional vehicles: they need to take in account the existing traffic, navigate a complex environment, and deal with weather conditions.
Why? If the AI can write it, just ask for it yourself.

I'm not very excited for heaps of AI code to get released. I basically consider that already happened.
The standard AlphaZero doesn't handle that.

If it were just one agency, sure, but we have evidence that State, DARPA, and FBI all have their hands in the TOR cookie jar. It would be naive to assume that CIA and NSA aren't there too.

Occam's Razor says that TOR is primarily a tool of the USG for enabling intelligence & influence operations, particularly those involving low-level assets without clearances (e.g. color revolutions), and the stuff about "consumer privacy" is an unreliable side effect.
I don't ever review them. If I need a note later, I'll find it. If I don't, then I won't. It's ok. I never regret writing anything even if I don't come back to it. The result of writing a note is not just the markdown file, it's also the thoughts I have as I write, thr decisions I make subconsciously, the new neural pathways I create in my brain. Writing is immensely useful even if I never read what you wrote wver again.
Sure!

I use them all the time. Recently I got ChatGPT to read a 50-100 page interface spec for a protocol (mostly structured prose as opposed to a typed interface spec) and skeleton out go client and server stubs. That probably would have taken me a day of copy/paste/check but with a few round trips I got acceptable results in under an hour.

Then I wanted to get some particular features out of a rust server that implements the protocol. I don't actually know Rust and the syntax is not superficially accessible to me, but with LLM I was able to one-shot translate a number of structs and functions and get a high-level idea of how stuff was working. I was able to port the features I wanted over pretty quickly. This was not entirely straightforward because async was involved on the Rust side but I wanted to use a more sync approach in the go client.

I also use it a lot to write out test stubs / skeletons. I paste in a bunch of interfaces or functions I want tests for and usually a pretty good starting point pops out. If it wasn't what I wanted I can refine interactively.

Overall I am very glad these tools exist now. Right now they're not doing anything for me I couldn't do myself but they help me maintain velocity and avoid getting stuck in gumption traps.
this is the way!
Wouldn't presence of the key address most of this?

Sure, they can steal the car AND the key, but more often, it's the car alone.
Density doesn’t mean anything at the ion level. Yes, lead has a higher atomic mass, but at the end of the day it’s about momentum and energy. If they can shoot a Mo2+ out twice as fast as Pb2+, it’s about them same.
Has there ever been a case of a nuclear project that came in under the worst case projection? I'm sure there have been one or two. But typically nuclear is known for blowing past the cost estimates, not staying within them.

Got a good discussion about this on LinkedIn for those interested: https://www.linkedin.com/posts/peterejhamilton_a-few-weeks-a...
Keep in mind you need to multiply those power numbers by capacity factor. Solar in California is at ~29% capacity factor (much higher than I expected honestly), while nuclear is generally around 92%.

That is, Diablo Canyon actually puts out 2,070MW of power from it's nameplate 2,250MW. While 4,779MW of PV in California will generate 1,385MW of power.

So, they really only added half of a Diablo Canyons worth of capacity last year. (Still an impressive amount of power, but not as much as it seems).
I agree, I think they need an example or two on that blog post to back up the claim. I'm ready to believe it, but I need something more than "diverse customer tasks" to understand what we're talking about.
Is it possible to mark the encrypted data-packages that leave your house?
Basically, this:

Data is encrypted on my computer but the router is a standard one from my ISP, running their software. Could they prefix my encrypted packets or send some kind of mark in between?

Computer encrypts my data. Router is running some OSS. Can this little box between house network and street prefix my packets or when my line connects to the street?

It definitely gets you started and is great imo for single developers or small technical teams.
Maybe it was something with the one I rented. The "slight turning force" was about 2 hairs away from "so much turning force that it disengages", and enough for a noticeable swerve in the vehicle path.

This one had a full FSD computer, and the depicted situational awareness on the screen was pretty neat with it classifying vehicles, pedestrians, construction cones, etc... but FSD was not enabled on the one I rented and was not able to be enabled since it was a rental.
Mac/PPC user here. The right thing to do is to support the 99% use case best you can, and leave dealing with the quirks of ancient garbage^W^W these wonderful machines of times past to the enthusiasts.

If you want to e.g. make use of modern crypto, the slow CPU is a far bigger issue than sourcing the random numbers.
Murder for entertainment probably exists, but is vanishingly rare. Prosecutions of CSAM frequently involve people actively soliciting either the production of more or the opportunity to participate. CSAM enthusiasts network a lot. Read some court documents dealing with real cases rather than thinking purely in terms of abstractions.

Another under the radar Apache project I've found myself using is Apache KvRocks

https://github.com/apache/kvrocks

It's a Redis compatible database on top of RocksDB, so unlike Redis it uses the disk instead of RAM, but you can control how much data is cached in RAM, obviously Kvrocks will be slower than Redis for uncached data.

Useful in situations where you want a KV data store that isn't limited by your memory specs but is compatible with everything that speaks Redis.
This methodology detected many hundreds of instances of known CSAM in the training set

How are local models better in terms of trust? GPT 4 is the only model I've seen actually tuned to say no when it doesn't have the information being asked for. Though I do agree it used to run better earlier this year.

The best open source has to offer is Mixtral that will confidently make up a biography of a person it's never heard of before or write a script with nonexistant libraries.
Ya, I think they even get status otherwise I’m not sure how electrify America’s app works in the first place.

I once charged at an L2 in Canada that involved a QR code, and then payment via a web form. In that case, a POS would make the setup too expensive compared to just putting power out there with a networked microcontroller.
It does require some state in the back for everything to work as it does.
You mean how VW directed their dealerships to deny there was a power problem while also directing their engineering team to come up with a fix?

Sounds pretty similar to me.
> Operating cost is undoubtedly much higher.

There you go - I would have said their operating cost is much lower. Paying the wages of the drivers for a year costs more than the car - even a car plus all those fancy LIDAR's.

Their development costs are a different story. I suspect only a company like Google could sustain it. But presumably it's one off, and if they spread it over 1 million taxi's in the USA it would only be a fraction of the revenue.

Those development costs have an upside too. It's a moat. If they pull if off they will have a monopoly. The will get away with being able to change just under the cost of a real driver for years. We may well be bitching here in a decades time at the obscene profits alphabet is making off us, and yet we have no obvious way out.

Nat.dev (openplaygroundl) is a nice way to access Claude if you don't have API access but want to explore a few settings not available on public facing web sites like system prompts.

That retail rate of electricity is mostly T&D; generators of electricity get far less than $0.10/kWh. Somebody else in this thread estimates that the $6B would result in $0.8/kWh, which is 50%-100% more expensive than new solar.

Sorry for that, did not find it
Isn't that negotiation already part of the CCS protocol? Otherwise 400v cars would be fried when they end up getting 800v from an L3 charger, or a Bolt would end up getting 300kW that it can't actually use
I thought that might be a possible interpretation, but then personal experience is just an anecdote and also not a thing when you're just starting out
The main reason is not technical, it's that the EU mandated CCS2 back in 2013. From then on, Tesla's plug became irrelevant, chargers must have CCS2.
Re-usability was once a 'lie' Starlink was also 'lie'. Their high launch rate was also consider a 'lie'.

100 people would mean about 10m3 per person. That sounds like more then some prisoners have had in isolation cells. Of course wouldn't be comfortable necessary, and in practice you likely wouldn't do that way.

Of course this talks about a situation where there is lots of infrastructure on both sides. No need to bring extra food or equipment. A pure crew ship. Near perfect system of water reuse and so on.It also presupposes some understanding of solar radiation or much better cancer treatment.

In addition you can think of a number of ways to expand volume.You can potentially stretch the ship, or widen the ship. You could have inflatable hubs to temporary create extra volume. The earlier version of the ship when that 100 number was first talked about was also much bigger then the current one, the ship designed has changed because they realized lower cost per stack and higher re-usability made more sense. Maybe it would require medically induce sleep (bear style).

100 is of course inspirational and might be off by a factor of 2-4x but to act like this statements are some unforgivable lie is ridiculous. Specially because there is are no contracts signed or promises made, its literally just 'this is our long term goal'. Complaining because a ship can 'only' transport 12 people to FUCKING MARS is just insane to me.

And in the end the cost per person is what actually matters, and that is what they are trying to reduce systematically. If you actually listen to Elon that's what he talks about most and what has always been the main driving goal. He talks far more about that in the interviews about this, the actual number he threw out are just estimation, and he makes that very clear. He even makes it clear that they don't know how to get there yet, they literally just working towards it as best as they can. 100 per ship is just one of many estimated numbers. A million people to self sufficiency. 1000 ships operational. Many others. All those numbers might be very wrong and Elon would admit as much. Its not the 'gatcha' you think it is.

And notice how you didn't defend your ridiculous 'pump-and-dump' nonsense.
