Some technical background:

Open-Meteo offers free weather APIs for a while now. Archiving data was not an option, because forecast data alone required 300 GB storage.

In the past couple of weeks, I started to look for fast and efficient compression algorithms like zstd, brotli or lz4. All of them, performed rather poor with time-series weather data.

After a lot of trial and error, I found a couple of pre-processing steps, that improve compression ratio a lot:

1) Scaling data to reasonable values. Temperature has an accuracy of 0.1° at best. I simply round everything to 0.05 instead of keeping the highest possible floating point precision.

2) A temperature time-series increases and decreases by small values. 0.4° warmer, then 0.2° colder. Only storing deltas improves compression performance.

3) Data are highly spatially correlated. If the temperature is rising in one "grid-cell", it is rising in the neighbouring grid cells as well. Simply subtract the time-series from one grid-cell to the next grid-cell. Especially this yielded a large boost.

4) Although zstd performs quite well with this encoded data, other integer compression algorithms have far better compression and decompression speeds. Namely I am using FastPFor.

With that compression approach, an archive became possible. One week of weather forecast data should be around 10 GB compressed. With that, I can easily maintain a very long archive.

Sometimes the purchaser is not the user. I've seen plug-in Prius bought with grant money... and never plugged in.
> unless you consider every instance of two buttons looking this way a dark pattern

The entire point of this pattern is to guide the user into a "default" option so using it for anything where the user is suppposed to provide informed consent is a dark pattern. The only places where it is not a dark pattern is where default choice actually aligns with the interest of the average user and I think that is hard to argue for a choice whose purpose is primarily to be allowed to better manipulate the user into spending more.
The EV6 looks stunning. Tesla design feels very old and boring now. Gotta be like 6 years since they updated the design right?

No :-) Come on now, there's no good reason to answer random/opposite from what you would normally do, just to skew statistics. Obviously this is the internet we're talking about, so there are bound to be "silly" answers and these count as well. We can't all think the same and answer the same ;-)
The trillion-dollar company is often less able to produce quality products than a small shop, because of bureaucracy and hubris and dead weight.

So while I agree that the business case for web apps incentivizes mediocrity, there is still plenty of hope for everyone else. If your startup has a really great web app with awesome UX, you will have a pretty big advantage.

I have had the following variety of problems:

* very occasional post upgrade problem which was fixed by the next upgrade or just a restore

* zigbee radio occasional issue which turned out to be a bug with the dongle firmware. Upgrading the firmware sorted me out. (Basically, I sometimes needed to power cycle before the zigbee network was functional)

* SD card corruption. This was the biggest pain, and required building the system from scratch once (since the backups were on the same card - oops!) and from backup one other time.

I never once had an issue after moving away from using sd cards that needed more than a restart - and this was maybe once in the last 6 months. I suspect the upgrade problems I previously had were also corruption related.

If you were willing to try again, I highly recommend the odroid with eMMC - it’s also more powerful (though pricier) than a raspberry Pi 4 along with being generally neater since all the plugs attach on one side and it doesn’t need an external usb for its disk.
...but do I have an internet connection and a laptop? When they invent VR, can I have one of those?
They contain extremely many symmetries. The Leech Lattice is certainly a uniquely symmetrical object.
PHEVs are pointless. All the disadvantages of an ICE vehicle with no benefit over a regular hybrid; they get worse gas mileage, the added cost (~4000-5000 dollars) is probably never paid back by the first owner in electricity vs gas, and they have less cargo room.
You picked a strange company to make that point.

GM sold 7k "plug in" cars in Q2 2022. That's compared with ~250k pure EV by Tesla. It's 1.2% of GM's total sales.

Their overall sales are declining for the past 5 years.

That doesn't look like a company that has figure out how to make EV at scale.

The supposedly "smart move" isn't reflected in GM's EV sales or their profit margins.
The point of the hypothetical situation is to look at a 'pure' case without external consideration in order to get to the crux of the problem.

Consideration of legal implications is missing the point of the exercise.

Is there any proof wearing a mask save ANY lives? People talk about this as if it were some fact, it's usually same people believing safe and effective vaccines, who quickly forgot vaccines were supposed to stop transmission, stop symptoms, they just keep pushing goal posts, while reality if you look at stats in highly vaxxed countries is that vaccines do really nothing anymore.
When you are certain your actions will result in the death of someone then I doubt the legal protections of helping someone is as clear cut as you think it is.

Maybe I'm wrong, I don't know all laws of all countries.

I'm hoping a lawyer would jump into this thread.
I tried out the Kia and Hyundai EV platform and found the infotainment incredibly bad. The Kia in particular is a case study in UX anti patterns. Toggles for switching the same capacitive buttons between different functions is almost a caricature of good UX in a car.

The Hyundai was better, but still everything was capacitive and unintuitive.

The Tesla big screen and UX is also bad, but I certainly wouldn’t put the Kia or Hyundai infotainment on a pedestal as a job well done. I am personally waiting to see what Honda or Toyota release.

A bigger issue (to me) is that EVs are just too expensive. You won’t save money unless you’re comparing an EV to a luxury car. If you’re comparison shopping an EV6 against a CRV you’ll never get the numbers to work. And if you’re in the market for a luxury car would you rather have a Kia or a Tesla??

Yes, it is the power of this manipulation — even seeing data does not help, but:

"Among the participants reporting child abuse (25% of all respondents), 48% had a tattoo or piercing" ― out of 100 people, 25 were abused and 48% of them (i.e. 12 people) have tattoos → 12 of 100 respondents have tattoos and were abused, while 28 just have tattoos.

By web app, I believe the author meant apps served in a browser, not a mobile app made from html/css/js with a cordova/capacitorjs wrapper. Also, google has problems delivering functionality in general. Have you tried using google home? It never works properly for me, and for some reason I can't log in to my family's home with my google workspaces account. Most things except for search are a mess there, and search is getting worse as well.
Only to decide to recommission them in many places, increasing the heat-attack rate for those trying to get to work on time through the 6 year long construction zones.
Regarding affordability, I think what most people do is the other way round: You do a bit of homework to see how much you can afford, which gives you a maximum price. After that, "simply seeing a number like $450000" clicks immediately because you just compare that to your max, and that obviously allows you to narrow down your search.

In any case, most property portals already have widgets showing estimates of monthly payments. And if they don't and this is a useful feature they'll just add it. Some have features to save properties, etc. (Looks like realestate.com.au is very similar to the main one here in the UK, rightmove.co.uk, and they also seem to have a "renovation estimator")

Overall, I think this is a important thing to consider: The features that are not too difficult to implement and integrate in those major property portals, and they will be available for free. So I think the question is not whether the idea has a market (it has one) but whether an independent, paid-for product is viable. If there are none that might tell you something...

My Bolt is awesome. I don't know how they would significantly improve it.

As long as companies look after brand names (tesla, faceook,) keep beeing seen as a “better place to work” the number of applicants will keep rising. This leads to the fact that people will not speak up or question bad behavior.

Don't read too much in to it, I just picked a random car company that had been around for a long time.
Yep. :)

And (as a side note) one could make a separate, static .cfg, let's say tiny.cfg and load it from shell with configfile, aka configfile /tiny.cfg.
Pretty much every company that tries to capture the environment around it uses a probabilistic model that takes in the raw sensor data and makes predictions about things in the surroundings. The random blinking you see on the Tesla screen is essentially saying that Tesla's model prediction confidence is borderline and changing from instance to instance. Is that great? No, but they can't do much using just vision data. What's the alternative? Show the cars even when your model is not confident anymore just for user experience reasons and give false sense of confidence? That's not ideal either.

Imo I don't know any other consumer car company that shows anything like that on their cars infotainment console. Companies like Waymo and Cruise do a much better job at capturing surroundings but they are in a different market where it makes sense to spend a ton of money on each car to add many LiDARs and significant compute in the car.

~35% (37% to be exact) not of all respondents, but of those who have tattoos (from those 40%).

From all respondents it would be 28% vs. 12%.

I think the implication was that competition has already come and BYD sells a roughly similar car (in terms of range and size) at a cheaper price, because they are willing to accept a lower margin than Tesla. Tesla might have to lower prices just to match BYD.

And to respond to a HN-er above who was mentioning that he/she found my question "distasteful" and "insinuating", yes, the reality today is that lots of people involved on one side of the current conflict in Eastern Europe have been receiving prizes and media attention just because of their nationality at this present moment in history, not necessarily because of their actual work in their respective fields. Glad to see that the "judges" (I have no idea who gives up this award, or how) behind the Field Medals have steered clear of all that and have sticked to merit.
Your reply reads quite snarky. I don't think further discussion would be productive, so I won't continue.
I think if you choose the option to kill 5 people 100 years from now, that 5 should not be part of your total kill count, because those people won't be dead for 100 years. In fact, it is possible you could commission a brick wall to be built somehow in front of the portal opening at the other end to divert the trolley in time, sparing those people, since the future (in my opinion) is not certain.

Petrarch pretty clearly was not using the word "dark" to mean lack of information if he considered the year in which he lived to also be "dark". Did he explicitly state he was talking about abundance of historical records anywhere, or is that something that was projected onto his writings later?

Renaissance humanists were famous for considering the Roman Empire to be the peak of sophistication and all things cool. They were also famous for going to great lengths to recover supposedly lost works of Roman literature, which were often found in obscure places. It seems quite unlikely those people would have been using the word "light" to mean abundance of literature given the difficulty they had in obtaining said literature.

Per https://insideevs.com/news/586195/tesla-model3-rwd-tco-toyot... 5-year Total Cost of Ownership of Model 3 SR is about the same as Toyota Camry for an average 10k miles / year driver.

And that was probably calculated with the old gas prices.

And if you get the new usage based insurance from Tesla (available in 8 US states) then you might additionally save on insurance (see e.g. https://twitter.com/jd_average/status/1543083099701010434 saving $1.6k for 2 cars compared to Geico).
