> This is my fear with everyone eventually plugging in their electric vehicles at 5pm

Household- or neighborhood-scale battery banks make a lot of sense in the near term. Because they are stationary they don't need to emphasize light materials and can focus more on cost efficiency and charge/discharge rate than mass or energy density using more readily available materials and cheap production methods. With relatively simple BMS you can charge your EV now and recharge the battery at off-peak times if you need to use it again in the evening (lots of people do).
Good question! At what cost do the externalities of fossil fuels come? What is the cost of inaction?

What are you trying to achieve with this banal line of questioning?

You’ll need an SSN to open most credit cards, it’s very difficult to get a credit card without residency. The business banks that specifically cater to overseas founders (like Mercury) make banking easy but that doesn’t extend to churning credit cards.

Edit: put simply, it’s very unlikely that opening an LLC will help you in obtaining credit cards as a non-resident.
> Tesla uses the the tri-motor system from the Models S/X Plaid on one axle of the Semi, which seems both dangerous and needless, given the lack of concern among Semi users for quick acceleration

Jay Leno did an interview with one of the Tesla Truck engineers the other week, I believe he mentioned each axle is geared differently. One specifically for highway speeds and the other one disconnects for optimal efficiency once up to speed.

I'm not sure it would follow. as part of the act is to allow other apps to request interop in these services like iMessage or WhatsApp.

But I guess it was worth to try this instead of directly opening iMessage for interop, for business reasons.
> I've been told team meetups, even once a year, are not possible

Look, if you really love the environment except for this remote thing, here's a couple things you can do before you quit:

1. Earnestly say that you love the place, but getting some mixed purpose face time with coworkers is a make or break issue for you. If you convey that you really mean that (you seem to), and they think you're a good fit too, they may revisit what they told you above. Think of it as a salary renegotiation, but you're looking for an essential benefit rather than a raise.

2. Just suck up the cost and organize those "meetups" yourself (i.e. make plans with your coworkers privately). Here, if you wanted to, you can think of the cost as a deduction from your salary. Do you still feel well-enough paid once you account for that deduction?
Oh it absolutely helped.

Thanks for being one of the OG early adopters who kept me energized and motivated over the past couple years!

And best of luck with the final boss: One More Year Syndrome.
Show HN: Animated Songs with Graphviz, Python, and GPT-4
Hey all,

I've been playing around with generating animations that sync to music.

Figured I'd share and get some feedback, and see if anyone has any resources to share that I should look at in this space.

I'd like to expand this to 3D next.

I plan to open source this, but I've not done that yet. The code is still a mess, I'd like to clean it up a bit before sharing.
Nice try but the West has moved on to Enlightenment and Liberal values and has integrated freedom of religion inside of it. Maybe Islam should do the same, or at least not see the people who do this as sub-human infidels that deserve death (I'm talking about the extreme interpretations).

Alternatively as you suggest we could return the favor and revive the crusades.
Perhaps because it’s easier to “make it” as a magician. As a wannabe photographer, it’s exhausting trying to build an audience/clientele, manage your social media presence, get accepted into local art shows or crawls, etc. all while still building your craft and buying the gear. I don’t know what it takes to get to a satisfactory level of being a magician, but I imagine you can at least get a few shows with family/friends right away.

As I was writing that (still going to keep for posterity’s sake), I’ve realized maybe it’s because there’s much more play in their art. It’s very whimsical.

I can't accept Christ's mercy after I die because I'll be dead and won't exist anymore.

I'm glad that you find solace and meaning in your faith, but you may be too close to it to realize that the Church exists to control you, not to bring you salvation.

It's a personal choice, and I respect that, but my original point is that there's an undercurrent of war to remove this choice and that gets ignored by people such as yourself because you already live in such a world and you like it.

The analogy I like to use is this: imagine if there was a revolution and somehow muslim evangelicals took charge of the government and put the state under Sharia Law. This has happened in other countries, it's not pure fantasy.

Now think about if you'd like to live in that society. I can guess what the answer might be.
I believe it's just a side effect of getting a BEV to that mileage range. Only the performance oriented Teslas put any thought into the acceleration, because it's already plenty fast by default.
I s'pose we'll find out as this makes its way through the courts :)
Thanks for the ad hominem, but you've proven nothing, shown no proof of anything, demanded proof and then moved goalposts when provided with citation from a noted medical establishment, and you've argued disingenuously.

I hope you have the day you deserve.

The burden of proof is now on you, so you lose by default since you've provided nothing to back up your claims. And that's the end of this stupid, pointless "conversation".
Looks like the design requirement for a heavy duty vehicle were not properly followed. Though that's how tesla builds something like software build find faults then itteriate. For light duty if you can get chinese $2000 truck with a hydraulic lift I think china is going to takeover the world's vehicle manufacturing markets.

This is good news people. We’re just not very used to them anymore.

Scaling to 365 days and 8 billion people is harder than 10 million and 6 days. But it’s a nice step in the right direction.
> The annual cost of running such a machine on AWS (with SSD included) is ~$4000

Are you sure about this estimation? Because Digital Ocean offers 2vCPU + 8GB machines for $25 / month, which is more than 10 times cheaper.
Thanks! That’s wild, my guess is cloud providers will substantially hike up compute cost and/or lower bandwidth cap per core as a result of this
What do your racks do if they lose site power?

What happens when your own HVAC dies and your DC has about 4 hours until it overheats?

(I'm a software engineer who previously built and maintained racks of bare metal. Never again).
It was "during the installation process", probably due to mucking with high voltage mains and not actual use?

BTW my car charges at midnight. Super easy to set up that way. I override if I have to but 99% of the time midnight is just great.
If you replace a coal burning power plant with a natural gas one you reduce emissions more than if you replace a natural gas one by a solar or wind power plant.

In the state of Ohio there are 15 coal power plants. Its 5 neighboring states count among them an astounding 119 coal power plants.
> The nuclear option will eventually be to just ban Google accounts for using any ad blocking.

The collateral damage from that would probably lead to the mother and father of all class-action lawsuits, literal Acts of Congress, and EU fines that Google would have to get a second job in order to pay if they don't try to break them up outright.

EXoDOS 6 released – the most thorough DOS preservation project
eXoDOS includes every DOS game ever found, manual scans, additional media to contextualize the games. It supports every build of every game. There are ready-made setups so you don't have to worry about config.sys/autoexec.bat or installers. It supports every SKU of a game, from CGA to SVGA, and every sound card. You want to hear the Gravis Ultrasound version of a game? You can.

It's probably the most impressive preservation effort I've seen for games, after the Internet Archive. The team has spent years refining this release.
Batteries on semis dont make much sense to me.

Hybrid systems on heavy inner city vehicles make a lot of sense. As do hybrids in mountainous areas.

But long distance hauling? BS. Semi engines are large with very low power to displacement ratio -> they are very fuel efficient. Truck builders' customers are very sensitive to fuel consumption.

I find it very hard to believe that marginal grid power (ie thermal plant), through all the transformer and transmission losses can beat a semi's diesel.

EDIT: even if the semi's electricity came from magic, the opportunity cost of putting so many batteries on a EV semi vs. a small fleet of hybrid commercial vans more than blows the comparison in favor of hybrids.
At the cost of building enough solar and wind farms to supply the nation I would guess, with additional costs to upgrade the distribution infrastructure for smarter load balancing, etc.

It's quite possible Portugal has put out a white paper on their transition toward renewable energy that you can find with some hunting about.

Wikipedia has a rough overview that'll provide some points to drill down further into if you're interested in the per capita comparative costings of a hybrid national power scheme.

I'm really hoping the (not Tesla) USPS electric NGDV doesn't experience this same over-promise-under-deliver rollout. The ICE variants of those new vehicles get only 9 mpg (when the AC is running, 14 when it's not).
>Also, end-to-end encryption is not part of the RCS specification, but is a proprietary extension to RCS that Google has made exclusive to Messages by Google.[1] This feature should be made open and added to the actual RCS specification so that Apple and other vendors can make use of it.

The sourcing here is a bit spun. "An insider" turns out to be a random driver someone found at a truck stop?

> This is why it was with great fortune to receive the details below, which were told to a trusted automotive source of mine by a PepsiCo employee who happened to have time for my friend’s questions about the Semi at a charging station the other day

Note carefully the weasel phrasing: the actual source is not trusted, just the intermediary!

I mean, the details given seem plausible. But would you trust your cab driver as an authoritative source for the business value of their employers rolling stock?
That's something that's basically equivalent to a golf cart with a bed on it. Hardly an example of anything useful except transporting some stuff around your own property.

Large collections require large buyers. Seattle's Bop Street Records closed a few years ago, with 500,000 records in stock. According to BSR's one-time website, the WSJ had rated it one of the top-5 in the US. It got calls from around the world.

In May 2020 the Times reported the sale of all the records - sight unseen - to Internet Archive.

Bugs related to concurrency - which is where you get race conditions and deadlocks - tend to pop up wherever there's an implied sequence of dependencies to complete the computation, and the sequence is determined dynamically by an algorithm.

For example, if I have a video game where there's collision against the walls, I can understand this as potentially colliding against "multiple things simultaneously", since I'm likely to describe the scene as a composite of bounding boxes, polygons, etc.

But to get an answer for what to do in response when I contact a wall, I have to come up with an algorithm that tests all the relevant shapes or volumes.

The concurrency bug that appears when doing this in a naive way is that I test one, give an answer to that, then modify the answer when testing the others. That can lead to losing information and "popping through" a wall. And the direction in which I pop through depends on which one is tested first.

The conventional gamedev solution to that is to define down the solution set so that it no longer matters which order I test the walls in: with axis aligned boxes, I can say "move only the X axis first, then move only the Y axis". Now there is a fixed order, and a built-in bias to favor one or the other axis. But this is enough for the gameplay of your average platforming game.

The generalization on that is to describe it as a constraint optimization problem: there are some number of potential solutions, and they can be ranked relative to the "unimpeded movement" heuristic, which is usually desirable when clipping around walls. That solution set is then filtered down through the collision tests, and the top ranked one becomes the answer for that timestep.

Problems of this nature come up with resource allocation, scheduling, etc. Some kind of coordinating mechanism is needed, and OS kernels tend to shoulder a lot of the burden for this.

It's different from real-time in that real-time is a specification of what kind of performance constraint you are solving for, vs allowing any kind of performance outcome that returns acceptable concurrent answers.
1 MW charger per truck, if you need to super charge. Equivalent to approximately 1000 homes.

This is a huge burden on the electrical grids, and Tesla or EV's get to hand that problem to someone else.

The only way this makes sense at scale is if we had nuclear power, and charging was done at night.
L4 was developed in the 90's. Operating Systems like Amoeba, which were fundamentally capability-based to a degree that even exceeds L4, were a hot research topic in the 80's.

L4's contribution was speed. It was assumed that microkernels, and especially capability-based microkernels were fundamentally slower than monolithic kernels. This is why Linux (1991) is monolithic. Yet L4 (1994) was the fastest operating system in existence at the time, despite being a microkernel and capability based. It's too bad those dates aren't reversed, or we might have had a fast, capability-based, microkernel Linux :(
Personal Data lake Draught syndrome / Data Impaired Persona Personality?

Not for AI friends, but for AI social agents that automate social interaction on your behalf; microblogs, videoblogs, memeposts and discuss online on your behalf - for the users that starts using AI agents too early in life and have too little data to imbue the agents with a personality that stems from their own voice and expression?
> This is my fear with everyone eventually plugging in their electric vehicles at 5pm

First off, it said during the install. So evidently it wasn't load related anyway.

Second, I used to live in a little town of well under 50k people. The local coop gave a couple hundred dollars in rebates for the installation of load management on their water heaters. I'd expect this would get solved in basically the same way. The total gwh isn't a problem, the gw is, and that's fairly easy to solve problem.
Some of the most sensible and (to me) sane famous people are magicians. Penn and Teller. James Randi (RIP). Derren Brown.

"Mastering Development Workflows with Nix: Part 1 - An Introduction"
Ask HN: What skills have you gained in 2023 so far?
Hello,

This is almost coming to an End.

What are some useful skills you have gained this year
It's a 10,000 line .CMD

I'm honestly kind of impressed
It's more that DuckDB and Clickhouse make it wicked easy to query data on remote servers or object stores in a fairly efficient manner.
Well, you see, the new fancy construction has to pay off its construction loans so it has to rent at an increased price. The small apartment buildings have to match it, or they’re simply leaving money on the table.
Some interesting thoughts, but a fair amount of obvious FUD too. And I'm not even a Tesla fanboy, far from it.
We need to go to net zero somehow. With carbon capture or carbon offset technologies near non existing, we have to make the switch sooner or later
They don't, but they do want good speeds up steep grades. That was the real purpose there.
The article mentions the source:

"The nonprofit Media Matters drew attention to those statements and noted that IBM, Apple, Comcast, and other companies all had ads placed next to pro-Nazi and pro-Hitler content (not posted by Musk) on X."

Almost exactly the same as DuckDB then - I measured ~287MB.
On one hand, solar and wind are very cheap - significantly cheaper than fossil fuels. On the other hand, you still also need either a significant amount of fossil fuel capacity or energy storage available to kick in during hours when solar and wind can't provide as much production. So instead of building enough fossil fuel production for 110% of your peak need, you might lower that to 50% and then still also build 110% of your need in renewable energy -- so you'd be over-capitalized at a total installed capacity of fossil fuels + renewables at about 160% of peak need.

So, marginal cost is lower. Total capital outlay might be higher. Portugal provides energy at an average of 9.7¢ / kWh which presumably is high enough to pay back all the capital costs in addition to the marginal costs. Mississippi only has 1% renewables and provides electricity at 11.55¢ / kWh.

So it would appear at a very rough glance that the answer to "At what cost?" is..."Negative cost".
Thanks for the advice. We lost one of our staff engineers last month to the same issue so I might be able to leverage that in a negotiation. The second option is honestly what I might end up doing.
Well 750kW with a 700kWh pack is only a bit above a 1C charge rate which .. is not terribly much at all. Not sure what this says about the other statements in this article.
Thank you for asking this question OP! The discussion has been really interesting. And good luck with the startup! Hope to see it on a Show HN soon.
Totally understandable but just say that in the post then :)

DuckDB has been a godsend to me for a certain types of stuff (mostly accessing very large parquet files over S3)
You can “add” SMS users to iMessage groups, if the group consists entirely of phone numbers and you’re on a device that supports SMS.

The newly created SMS group doesn’t replace the thread associated with the original group, though, so it’s easy for the group to fork when this happens.

Unlikely this will change with RCS.
You dont need a fast 0-60 in a family car either but people buy Tesla sedans for that purpose all the time.
lol police reports don't do anything but establish potential liability if the police ever take any action. have had laptop and other things stolen in this city and police never took any action whatsoever. the police only do something when you have somebody to advocate for you like an insurance company (e.g. if my car got hit big time) or a lawyer.

that's why we need regulation to fill that gap. e.g. the DMV and City should track Uber accidents. especially since Uber drivers don't have to get e.g. taxi medallions etc.

in this case, Uber has the actual location data, identity of the driver etc. but instead they choose to ignore it, or even worse do things like greyballing etc
More like a weird arms race where no one actually thinks about what they are saying or reading anymore and you are drowning in word soup. After all words are just tools to achieve some goal.
> the only relevant server implementation

That's not true. Mavenir offers an RCS platform that T-Mobile has been using up until recently. A renewed interest in RCS due to Apple supporting it might end up with their platform being more sellable.

This seems kind of par for the course. What I find strange is that there are busses[1] operating economically with similar time of use (but not top speed) requirements. The whole "car parts scaled up to truck size" is super on brand for their chief technologist. I'm also seeing a bunch of Rivian trucks and Ford E150 lightnings on the roads around the Bay Area which, for me, doesn't bode well for the launch of the Tesla truck either. If the Starship blows up tonight I imagine that's going to add stress too. I really wish Elon would pick cars or rockets and focus, that could really help the world. I'm not holding my breath though.
