Battery preconditioning is automatic, when a Supercharger is picked through the Navigation map. Whether it will be sufficient, that depends on the temp and distance to the charger.

Latch problems in freezing temps is not new. Some drivers even work around the frozen connectors by parking sideways (!) to the charger then bringing the connector indoors just to warm it up enough for the moisture to thaw out. Don't know how long this could take.

Perhaps, some heated receptacles on the charger or some antifreeze laced cradle could deal with that. Again, this is the reality of wider EV adoption, extension of field-test. So some adjustments are due.
I suspect you may be interpreting this a bit too broadly, and it's obviously personal for you. Part of work is, nearly invariably, social.

Not wanting to get Friday beers with the team shouldn't really be a factor.

Not being able to communicate smoothly and effectively with them in a work context absolutely is.

I suspect the poster you are responding to is focusing on the latter, and you on the former.
Interesting stuff keeps happening in PostgresLand. This uses Apache DataFusion, first think i hear about it, but from reading the docs it seems like it already offers build in SQL interface atop of Apache parquet and Apache Arrow. What is the difference between this two versions of SQL. Can I still use my favourite pl/sql function together with a deltalake table and does this play nice with other kind of tables?
Maybe one of those sites that come up when you search Google for 'track package' is selling tracking numbers?
> It's high time the EU forces companies to design their hardware in a way that allows the user (or a recycling company!) to replace the batteries inside without destroying it in the process

Why? The battery pack is external. I have not ever seen a requirement that battery packs themselves need to be repairable. Not many devices come with external batteries these days, but do you really want to open them up to replace the cells? Where are you going to source reputable prismatic cells to use with such a device? They are also pretty delicate, you don't want most people handling them. If it used standard 18650 cells I could kind of see the point, but it would be much larger.

A recycling company can destructively open it up to recover the material.

A better 'mandate' would be to require it to accept third party power supplies.

> for fucks sake what happened to the USB-C requirement for electronic devices

USB-C would suck for this application. It already does for headsets like Meta's Quest, where you can use a link cable to a PC. You need to secure any USB-C cables pretty well if you don't want to risk damaging the port.
The point is that relative to pharma, the supplements industry has essentially zero regulation and essentially zero barrier to entry.

Anybody can get into that game, and they do, judging by the thousands of different supplement peddlers one sees on Amazon and at the local CVS. Some of them even stick around for more than a year or two.

It can be a profitable business, but it's sort of a race to the bottom. I'm a fan of supplements, but if you think that selling Vitamin D pills at Safeway can gave you power and money on par with an international pharma company selling lifesaving cancer treatments at $10,000 a pop or whatever then what are you doing talking to me on HN? Go bottle some pills and think about what kind of superyacht you'll be buying.
Agreed that I don't think this particular case is a hallucination, but keep in mind noise can be consistent noise if it's a deterministic process with the same inputs. Same idea of setting a seed for a random number generator.

Even then though I'd be wary of simple changes to the prompt ensuring a different initial variable state, in case some input variation might be 'projected out', either in preprocessing or in one of the intermediate layers.
A16Z: The Abundance Agenda
I think the pulsation is there to help regulate the breathing. Many people take fast and shallow breaths, esp. when they are stressed out.

Because evening out the speed and taking deeper breaths help calming down with a couple of mechanisms.
There are no till drills that are being sold exceptionally cheap (~$800 US) and show up as the first google ad that are rumored to be an empty box shipped from the country of origin (not China) with incorrect paperwork that gets stuck in customs. Most people say they get their money back through CC or Paypal but maybe a few don't check? Either way it was plausible enough that I did not purchase. The market is small farmers and hunters planting food plots. You can use an old repurposed grain drill if the grass is super short/overgrazed and you can fix it, ~$1500 used on marketplace, or buy a small 4' (no tires/3 point hitch) no till drill US made low end ~$8k. So it is "too good to be true".
I've never liked the "my" prefix for labels because it wasn't immediately obvious whether "my" referred to me, or to the person/company/entity/software which created the thing.

This is particularly annoying when error messages are written from the point of view of an entity or fictitious person, e.g. "Sorry, I wasn't able to..." but things on screen are labeled "My..." Is "me" the user or the software?
They better not, I don't think I can handle that much schadenfreude.

I don't see it as something to be angry about. Probably what happened is it was trained on some crappy stock images where every "doctor" was a white model and they are trying to negate that propensity to repeat the stereotype.

For what it's worth if I ask it to draw doctors in Uganda/Siberia/Mexico/Sweden it has 0 problem drawing a bunch of doctors all of the same race if you really need an image of that.
Feedback:

- This is great to link to breathing

- After reading multiple breathing books (Breath by James Nester, Outlive by Peter Attia, Oxygen Advantage, etc.), there's a lot of evidence to breath slower. Specifically, 5.5 seconds in, and 5.5 seconds out, make the dot match or be closer to matching that rate could actually cause a lot of physical benefit by people matching with it

- Alternative if you don't want that, make it a control setting so someone (like myself) can do it.
I do own some Apple stock, but agree. Maybe I'm old school, but if I don't like a companies product I just don't buy it. This isn't a situation where anyone has to buy Apple products. ~65% of the EU has done just that. The whole blind hate is very weird to me.
Yes and no, depending on what you mean.

The custom types/indexes introduced by PostGIS won't work with deltalake tables. Even if it were possible, the benefits of using deltalake tables to execute geospatical queries are unclear, since PostGIS indexes are already optimized for this task.

But, what ParadeDB enables is for geospatial tables and deltalake tables to exist within the same database.
I found the piece difficult to read as well. That said, the author wasn't writing it with you or me in mind.

To me, the author was writing in a way that made sense to them, with no regard to how it would be perceived. People will either get it, or they won't.

That's what makes it art(in my opinion)
From the archived page:

The funds are available in a day or three. There is a big difference between cleared and reversing fraudulent transaction.

Are you requiring people to check their statements every week to find fraudulent transfers? Are people who go on vacation screwed? How do you handle instantaneous transfers when the funds are available in seconds?

For example, someone asks to use your phone and you foolishly give it to them. They make a bank transfer when you aren't looking. With instantaneous transfer, you are screwed caused the funds are already available and fraud report isn't allow.

It might be possible to make the banks responsible for fraudulent transactions since they are ones that can do the verification.
I am not sure that I agree. Engineering is a world of tradeoffs. Juicero said "we are going to overbuild every component even if it means the company goes out of business". Welp.

Most impressive to me is when every unnecessary component has been removed, and every remaining component is as simple as possible. (The example that sticks in my mind is the humble $5 drip coffee pot. No moving parts except the switch to turn it on!)

I don't know how "victim blaming" became such a taboo. There are plenty of cases where the victim could have avoided the problem entirely by taking easy, sensible precautions, but nowadays if you point those things out (for the benefit of future potential victims), you're an evil Victim Blamer. People have agency--we're not just helpless sheep walking through life getting inevitably victimized by things totally beyond our control. It should be OK to talk about preventative measures.
I got a Ryzen 7 2700X, cus it seemed to have good benchmarks for the price.

I have a vague feeling I might have been happier with less cores but faster ones. A lot of games put all, or almost all, their load on one core only, particularly older games.
A lot of old games have amazing modpacks for them nowadays and I often run into CPU bound slowdown and lagspikes

For the email validation I would have used an ecto schema, since most cases you won't just be validating an email address in isolation:

defmodule EmailSchema do
use Ecto.Schema

import Ecto.Changeset

@primary_key false

embedded_schema do
# here is your type validation right off the bat
field :email, :string
end

def validate(email) do
%__MODULE__{}
|> cast(params, [
:email,
])
|> validate_required([
:email,
])
|> validate_change(:email, fn :email, value ->
cond do
not is_email_address?(value) ->
[email: {"invalid email address", [validation: :email]}]

not EmailAddresses.is_available?(value) ->
[email: {"is unavailable", [validation: :email]}]

true ->
[]
end
end)
|> apply_action(:insert)
end
end

case EmailSchema.validate(email) do
{:ok, %{email: email}} ->

{:error, %Ecto.Changeset{} = changeset} ->
changeset.errors[:email]
# Can be all of these in the same list, or be any one depending on the validations
#=> [{"is required", [validation: :required]}]
#=> [{"invalid email address", [validation: :email]}]
#=> [{"is unavailable", [validation: :email]}]
end
yeah, Gibson pretty much admits that his cyberpunk was inspired by his love of certain prose styles and how other writers could imply an entire world with a few well chosen neolgisms (and his distaste for Golden Age scifi tropes), and that he knew almost nothing about the tech and at the time of Neuromancer had never even been to Asia. In that respect Stephenson is the opposite: even in Snow Crash which is basically caricaturing cyberpunk, he feels the need to explain how everything works. Which doesn't necessarily move the plot along on, but there's more depth to the worldbuilding even when the ideas grate.

Don't think you'd pick either of them for their characters
Well, if you change your email address, I guess you just don't receive the message. I don't think there's any way around that unless you maintain an unbroken chain of email forwarding from older addresses.
With the release of Ryzen in 2016/2017 the bare minimum upgrades Intel was pushing YOY no longer worked in the market. Since then the CPU space has been very exciting, you've been missing out.
Yeah, there's a huge difference!

At relativistic speeds (AKA speeds you can express as a significant percentage of the speed of light) energy increases exponentially as you get closer to c.

Put another way - since the energy of an object is infinite at the speed of light, then the energy needs to keep getting bigger and bigger as you keep putting 9s on the end, since if you're going .9c your energy is not infinite, while if you are going .(9)c your energy is infinite.

To actually answer your question, the energy of an object going at .9999c would be about 50x the energy of an object going at .9c.

Please tell us more. Did 6 line commits get rejected? How did anything get done?
OK, maybe this is a silly question, but if a function that is written once always refer to the same hash as when it was written, how do you update functions?

For example, if I have function A that calls function B, in today's languages updating function B would just work (A will call updated function). My understanding is that updated function B (we can call it B'), would not be used.
Wait lists for a manufacturer are somewhat interesting. It's interesting that Tesla and Toyota both sell cars faster than they make them, and can get away with making new car buyers wait for months.

Wait lists for a single model? I mean, maybe Hyundai just aren't making a lot of EV9s.
> If someone figures out how to make AI models run on an iPhone with zero battery use, everyone goes "yay!"

This is what I call wishful thinking.

I never said Bitcoin and AI have similar energy use patterns which is the argument you are keen to make. My original argument was that AI usage is going to be worse than Bitcoin in the long run. With some AI farms using ~3000W per server, it's a no-brainer where this is all headed. Add in the fact that AI has so far proven to be more popular at launch than Bitcoin.

Just because you can optimize models doesn't mean that people won't want or need bigger better models to train/use.
Why go through the expense of engineering and manufacturing a bomb, and then use it for a different purpose? If you want an electricity generator, engineer and manufacture for that. Or are you thinking of using excess bombs?

I want to say that fusion bombs require more energy input than they output, because until recently nobody has been able to create fusion reactions otherwise (and now only in a very limited way). But is that true? Fusion bombs release an incredible amount of energy. Maybe it's that they release it all at once, but still, how does that equation work out?
Unison was huge while I was at Amazon, but I always preferred rsync for the control (sshfs too but you had to ensure to set some flags for when you de-docked or changed wifi ap). One of the biggest gripes I had with it is thankfully fixed though (used to need same client and server version, nowadays they permit some drift assuming no breaking contractual changes).

I'd also recommend setting up some ignore rules for build artifacts, etc, which definitely increases complexity but avoids constantly syncing build artifacts you don't care about or with erroneous symlinks etc. IDK at that point I figured rsync was easier, as it's a more commonly used tool for other purposes, and I'd rather learn fewer things with huge functional overlap if given the choice.

Ask HN: Recommendation for Intermediate CSS Course?
A co-worker asked for a recommendation for a good CSS course for them to learn further. They are not a total beginner and can do fairly complex styling and the like, however, they have been 100% self taught and so have picked up things that are just the wrong way of doing it.

Most intermediate courses I've found focus on CSS frameworks or precompilers and the like, he doesn't want this as most of their work is landing pages etc so the CSS course needs to focus on plain CSS with HTML.

Any recommendations?
