Thermal storage at so high temperatures is even less practical than any other application.

Thermal storage at low temperatures is cheap and easy with molten salts.

Thermal storage at over 2000 Celsius degrees will be extremely difficult, due to the difficulty of preventing heat losses.

The best would be for the hot body to be stored in argon, because in vacuum it would evaporate and heavier inert gases are expensive. The storage vessel would be very expensive in any case, being made from multiple layers with high temperature resistance, an external surface with high reflectance in red and infrared and other layers with low thermal conductivity, so it is hard to imagine that it could have a size large enough to store much energy.

Another obstacle is that the available power is determined by the emitting surface, not by the volume of the hot body, which is another obstacle for scaling to large amounts of stored energy.

Another obstacle to scaling is that when the hot body cools down the conversion efficiency drops extremely quickly (fourth power), which means that it could store energy only e.g. by being heated and cooled between 2400 and 2100 Celsius degrees.

So only a very small fraction of the thermal capacitance of the hot body can be used, many times lower than when the heat stored in that body would be used to power a closed-cycle heat engine.

So no, these devices may have some useful applications, but energy storage is certainly not one of them, because they are much worse than almost any alternative. Even storing compressed air in a pressure vessel is much more practical.

>Prove that the earth has never warmed faster than it has in the last 100 years. Obviously, you cannot, the data lacks that sort of granularity.

This is silly. We know the precise chemical makeup of earth's atmosphere, and by extension its' climate, going back hundreds of thousands of years through antarctic ice core samples, which can be dated to a resolution of less than a hundred years. We are in an absolutely unprecedented time of change right now in the entire history of our species existence.

I love the idea that starving Musk of attention might inspire him to go fuck off and pursue some chill offline hobbies like fishing or needlepoint. But he's being groomed by this new breed of narcissistic conservatives who pattern themselves off of 1980's-era WWF wrestling heels, so the harder you try to ignore him the harder he will try to get more attention.

The best I can do is boycott Twitter/X so that he suffers the sting of a $44B folly.

On my EU wishlist is a law mandating standard form-factors for laptop batteries (and chargers). All batteries must be user-replaceable without tools and interchangeable with those from other manufacturers. There can be 4 to 5 different form-factors to address the various sizes and power-profiles of laptops. Batteries must have standard voltages and amperages but OEMs can differentiate themselves on other factors like mAh capacity, longevity, etc. Kind of like AA, AAA batteries but appropriate for laptops. Any laptop that doesn't conform to the standards should be hit with a 50-euro enemy-of-the-planet/douchehat tax (rather than an outright ban). The industry is already there since most laptops are designed by ODMs like Clevo and Compal. The last 20 years has provided little evidence of innovation happening on batteries and chargers in the budget segment. All the custom chargers and battery sizes are designed purely to force incompatibility on customers- for planned obsolescence, to reduce competition and charge more for after-sales support. Such a law would stop this practice by OEMs of engineering planned obsolescence into their bottom-tier cookie-cutter clevo-crap but still allow companies like Apple to "innovate" on vanity metrics like slimness. An industry consortium or committee (like W3 for the web or the 4G/5G committees) can be setup to propose new revisions to the standards (if required) once every 10 years (not lesser).
I recently rented a $65000 luxury car and it didn't even have built-in daylight savings adjustment. Owners have to dig into settings and fix it themselves twice a year. Cars are so far behind on basic software it is crazy.

I agreee building a home is toying. Building a _secure_ home that you can surive a night in would be be a game for me.

I did mean to explain that there are aspects of human behaviour that have aspects of toying or gaming. Sometimes - if it's rules based - it can be a game. There are lots of game theoreticians that worked on that in way more detail then i can explain here. Examples on behaviours that could be games or toys include: social status, clothing, gardening, mating, or for example drugs...

In the end it's up for discussion, because there are no fixed rules.

Ask HN: How to Get Back into Programming?
I studied CS as an undergrad at an Ivy and my programming skills were above average. After graduating I entered consulting and am now a growth equity investor. I like my job, but there's always a part of me that regrets studying a subject I deeply enjoyed for four years and then stepping away from it. A few things are driving me to get back into programming so I can become proficient again and start building. First, the AI rush is obviously going to result in lots of new companies and opportunities (aka ways to make money). Second, I feel like I would be remiss to completely lose my coding skillset (especially with all the copilot-like tools that make it so much easier now). My problem is I never coded outside of a class environment, and I haven't even done that in years. Does anyone have suggestions on projects to work on, bootcamps, etc. that I can do in my spare time to become proficient at coding again? Would like to avoid things like leetcode, project euler, etc. and instead focus on actually developing useful software (however trivial) to ramp up on basic software engineering principles / best practices.

The Future of Work(ers): Building Collective Power in the Era of Remote Work
From this article:

A Booking.com market manager in south-east Asia admitted at a recent industry event that payment delays were caused by the installation of a new payment system. Staff salaries were also affected, she said, explaining it as a risk they had to take.

From an earlier article:

In the company’s August results, CFO David Goulden said there were "lower than expected" IT expenses in the second quarter of this year, in part due to phasing IT spend into the third quarter, but did not outline what this IT expense included.

https://www.theguardian.com/business/2023/oct/03/bookingcom-...

Is this all just a fancy way of saying, "They 'restructured' IT and payment problems resulted?"
Funny, but no. You seem to have a limited view in what prompt engineering is and the history of prompting. Prompting in software engineering is more than just using LLMs. Before LLMs, there were static choices with limited variations of inputs like the old chat based applications, auto response options on phone menus, and other such applications. Today, in addition to the ChatGPT like applications reliant on LLMs, there are other ways of prompting a human for an input to use in an application. One such example is with physical gestures in virtual reality.

Here's the relevant section from what I can gather from parent's response:

> These are especially applicable in human-computer interaction interfaces where physical movements act as prompts.
That sucks, but I think Bluesky are throttling themselves by still having closed signups after all this time.
> They learned their lesson and even there don't do it any more.

State of the art in LLMs and Robotics – 2023
I was aiming to use LLMs with robotics in an upcoming project, and needed to first verse myself in what is the current must-know techniques in the space. To that end I read a ton of papers and wrote this article to try and suss out the best parts of current state of the art.

I hope this helps people; I'd be thrilled to discuss much of this as well!
In your example you're kind of mixing a DB within a DB (the index.json file is a separate database contained within the main database).

A better structure would be something like

users/<user>/projects/<name>/data/... etc

Now your file system is just a NoSQL database. All that data you would dump into an index.json can be stored in the file tree.

That would actually work pretty well as long as you limit operations that are kind of meaningless and disable features like symlinks.

Mounting hierarchical data as a pseudo file system is actually pretty common. EG procfs, devfs, sysfs are all pseudo file system that present structured data to applications on Linux through the guise of a file tree.
Why would use a database that is closely linked to a VC backed startup when PostgreSQL works fine you?
If you can't imagine a use case for generative AI in your email client or word doc, well I really don't even know what to tell you.

EUR Balance Stuck on Binance

Krita has issues with X too. Using X11/libinput touchpad: pinch-to-zoom doesn't work in Krita but does work in KDE's ms paint clone Kolourpaint.

I've also found Krita to be unsatisfactory for drawing pixel art. Select the pixel art brush and set it to be 3px wide, then draw a rectangle with the rectangle tool. This creates a rectangle with inexplicably jagged edges (http://0x0.st/HWyi.jpg). Turn off sharpness for the brush and try again, it seems to work now but selecting the background color with the similar color selection tool will reveal that the jagged edges are still present but very faint (http://0x0.st/HWyz.jpg). All of this happens with a 3px brush but not a 2px brush. It's bizarre. I suppose most digital painters don't notice/care about this, but it's a deal breaker for me.

I dislike the Krita icons as well. I would like colorful icons so my eyes can scan them quickly but some halfwit designer got it in their head that all the icons should be monochrome and there doesn't seem to be any way I can choose or create other icon themes.

I really want to like Krita, but it just doesn't work with me. All I really want is "MS Paint but with layers" but that's evidently too much to ask on Linux. I've tried more than a dozen painting programs and they're all disappointing.
> they will soon be good enough that they will be able to replace the work of the people that produced the content the AI was trained on

Let assume this is true. It then follows that if we train LLM on all books that are out of copyright, the LLM would be able to replace the "work of the people that produced the content" that is just about to go out of copyright. Feed this body of work back into the LLM and you should end up with something just as advance as what you get by feeding in works that are under copyright.

I'm not sure the assumption is true. But if it is true, using copyrighted material or only non-copyrighted material shouldn't result in a different situation.

you are commenting on this after it was corrected. so the snark is a bad look.

the error wasn't the typo in `indented`. it was that a single newline ("CR") is like an html space in HN formatting. it doesn't start a new paragraph. GP notes that he only used a single "CR" and thus his own commentary ran together with his intended (also indented, in this case) quote.
On thinking about it more I agree with you. A very simply soldered thing is maybe ok, but the vast, vast majority of soldered things are no-gos for repairs for non-pros. It's too easy to damage components and destroy the board, even if you know how to do it. If the Framework required soldering, I'd be very critical about it's repairability/modularity, so I'm being inconsistent.

Conclusion: soldering is not ok for repairability

Programming for astronomy is famously difficult, since you're always pushing the boundaries one way or another. That said the problem domain is fairly well specified and (as the article shows) usually well models. Mr. Feynman going to Washington showed what treating astro like office software can do, but it's a shame when an expensive project gets a fleshwound from something predictable.

This is going to be very bad for anyone with multiple Microsoft accounts on one computer. I don't see how Microsoft keeps OneDrive data separate.

Microsoft has not done a good job at keeping stuff separate. If you login to Outlook, Teams or any Office application with more than one account it becomes a giant mess. All of a sudden other programs like Edge will have one of your company policies like default home page applied.

Also authenticating with Microsoft accounts using Azure AD anywhere is a giant headache as Azure AD may have one login with multiple directories. So you're constantly having to re-authenticate & login with the proper AD account & proper "Directory selected".

I'm sure some older gray beards will respond with "Never login to your personal devices with a work login". That's great advice for plenty of situations but there are plenty where it doesn't work. Have a personal account & want to help your local church & non-profits out? Offer consulting services to multiple small businesses? While the Matrix setup looks awesome, it's not fun to login to 10 different devices or 10 different VMs.

I don't see how Microsoft is going to properly do security to protect your data from going elsewhere even if you only have one account, let alone multiple.

I like CoPilot, I love ChatGPT & overall I like most of Microsoft's products. But they're going faster then they can handle & they're very well known for not having great communication & cooperation between their large divisions.
You have to enforce a copyright, or any other license, contract, or TOS.

It's up to you (and a lawyer) to decide if & how to attempt to enforce it. Either way, it's going to cost you money, though going to court may enable you to recover these funds. DMCA may be another approach you can consider. Many times a letter from a lawyer is enough, although if they are not having any success, why bother?
No one said otherwise. There is already a case against them, their defense is that they don't know how it works, so it can't be true. This was clearly laid out in the comment I replied to, and the comment that reply was made to in turn.

Right, it only converts to v4 if both src and dst are 32-bit, which is fine in v4.1 too. Everyone can adopt v4.1 hardware/software without even thinking about it but hold off on using >32-bit addrs until they feel like enough peers are on v4.1. Yes it's only a one-way compatibility, but that's way better than v6 which is incompatible both ways, creating gridlock.

If you really want extra compatibility, idk if this is a good idea but it's an option... Go v4.1 using up to 40-bit addresses for now (but leave room for more). Translate a v4.1 TCP/IP packet with a 40-bit src and 32-bit dst to v4, truncating the last 8 bits of the src IP, provided the last 8 of the src port matches them. IPv4-only dst can respond fine. When that /32 v4.1 router receives the v4 response, set the last 8 bits of the dst IP to the last 8 of the dst port. So it's kinda like NAT except translating to a public /40 IPv4.1 instead of a private IPv4. Actual NAT on the /40 addrs gets the remaining 8 bits for the src port. And you just speak v4.1 without all this if the dst is >32 bits.
