Phase change materials are a way to store lots of energy at a given temperature.

You might have noticed how much time it takes to freeze something - that's because lots of energy need to be extracted from liquid water to turn it to ice. And that without even changing temperature - it all happens at 0°C. With other materials, you can have a similiar effect at other temperatures. This can be used to create a system that keeps a certain temperature even if energy flows into or out of it (until the phase transition is complete).

Blogs are parallel to research papers in a sense. They're useless without peer review unless you're already intimately familiar with the source material and able to critically evaluate the contents.

So Blogs are more useful when they're aggregated through a site like Reddit, where users have already done the vetting on whether the linked page is valuable. Reddit comments are invaluable to pages by adding additional context. Noting when the content has become dated or inaccurate due to external changes, etc. Sites like Brian Kreb's blog are the exception as the author is well known and respected. But the general blogs? It takes time to earn that community respect.

Then beyond that, how often have you gone on the hunt for something obscure only to run across 3 or more blog pages which look entirely unique, but have the exact same article pasted to them? It isn't that the contents are bad/wrong/inaccurate, but rather who do you trust? How much effort are you going to put in to finding which blog was the original, written by the expert and which ones are bots copying the info?
Create forums and message boards again. Give them topicality. Support RSS and open data transfer protocols. Manually append these places to the Google and Brave indexes.
Lately I have been trying a new LLM called Falcon that was supposedly created in the UAE but it was mostly trained on conversations with ChatGPT... the result is that if you ask Falcon who created it, it will happily say OpenAI. I found that really amusing.
dogging
You could potentially introduce an occasional prompt and check the answer against a few LLMs to see if they match.
> One moment I was perfectly awake, and the next moment I was hearing the sounds of people talking around me and I groggily became aware of my doctor getting me to acknowledge him.

Yep. I remember the nurse telling me to count backwards from 10 and I remember being a bit annoyed by it but still doing it. I don't know what number I got knocked out on. I don't even remember getting knocked out. The only thing I remember is hearing voices as I slowly woke up. No memory of anything in between.

> Is consciousness required for intelligent behavior?

No. Computers, machinese, animals, plants can display "intelligent" behavior. They have no consciousness.
I disagree that Vite takes a "kitchen sink" approach, and I disagree that the amount of features is relevant to "generations of tooling". But that's fine, who cares that I disagree? :)
People post Show HNs and link to substack.com? I guess I don't understand why medium.com would show up either, but I can't recall seeing a substack link for a Show HN.
I’ve found it preferable to build directly on top of OpenAI’s API. (I’ve also written a simple API wrapper for llama.cpp hosted LLMs.) Over time I’ve built a small library of utilities, including for summarization. It’s not that much code.

I don’t know if this is a spicy or a generally-agreed-upon take: my feeling is that, while LangChain was useful in that it helped the community codify some early intuitions about LLM invocation patterns, it’s basically a grab bag of partially complete somewhat disconnected utilities. It nods to composability but, in practice, its pieces often don’t fit together. On the Python side, it suffers from poor typing: when creating a chain, it’s often impossible to know what the full set of configuration options is without digging deep into LangChain’s code. It’s catch-as-can whether you can deeply configure specific sub-aspects of a chain.

There are other things I want in my own code at the moment, including keeping track of how many input/output tokens each of my actions takes, etc.

I dunno, maybe I’m the only one here. Curious what others think.
> But asking permission is not really an option, and I'll explain why using a different situation. We were also mandatory reporters, which meant that if we knew that a child was being abused, we had to report it to the authorities. This was actually a very high bar to climb, but once we knew it, we had a duty to report. It was a threshold after which it wasn't our decision.

I appreciate your response, from what I gathered it seems like your justification for not asking permission is "well that's not up to me, its higher in the chain". Which I understand, I'm not criticizing /you/ in particular, I understand you are a mandated reporter, I'm critizing the policy itself. I'm saying people who call suicide hotlines should be informed they are talking to a mandated reporter at the beginning of the call.

It may be a better way to go for a public forum like Reddit. Don't kid yourself though into thinking the non-profit foundation won't also be rife with petty politics, hidden agendas, and the usual crap. There will still be issues, and how to handle NSFW content is still going to be a big conflict.
Who are these people and why are they willing to work for a wage they by definition literally can't afford to work for?

The argument could be made around required PPE as well. There are people willing to work without it, why aren't we jumping on that opportunity? Could probably employe another person or three if we didn't pay for PPE for the worksite.

being in the irc room and logging it is enough and only requires access to the room.
Yes, I do. But I also see significant differences in our level of technological sophistication and adaptability compared to Homo sapiens during the last ice age.
Maybe the solution isn't federation, but a nonprofit foundation with an open source and relatively simpler codebase like Wikipedia. Wikipedia is the 800# gorilla in that space, but there's no ads and no perverse incentives and they aren't trying to lock down to prevent "theft" from AI companies, and the decentralization is through people being able to relatively easily setup specialized wikis.

I'm not sure the problems of federation are ever going to be solved at massive scale. Usenet and IRC were always problematic back in the 90s. Not even e-mail works well due to spam.

"It is impossible to de-rail a thread"

citation needed, I've seen many reddit threads degenerate into name-calling, logical fallacies, political posturing, and what have you. If they don't, my guess is it's a very focused subreddit that doesn't attract much general interest, or the mods are very on top of things.
Ask HN: Help me explain Chatbot vs. ChatGPT
I have been experimenting with ChatGPT, ChatPDF and other tools in my spare time. Last month I showcased some of the tools to my manager and casually mentioned that someone could use it to build a "Ask me questions about data" tool in a similar format. That proved to be a mistake.

First, he went ahead and shared this chatbot idea to his superior. Now in all our 1-on-1 meeting he is always pushing to create a chatbot.

I have tried explaining to him that LLM are fairly new. While the technology might be cool, ChatGPT isn't ready for prod releases. There are questions about data privacy. There is going to be ChatGPT Business but that is not out yet. Additionally, there are security issues and hallucinations.

But as per him Chatbot is an old technology. His colleagues at another company have been creating chatbots for past 3-4 years. So, he doesn't understand why I keep pushing back.

So, I want to share some info about these "chatbots being created for 3-4 years" vs ChatGPT.

Please help me with any links on Dialogflow or any other chatbot tech vs ChatGPT.
See, I completely disagree with this. I am absolutely certain that the economics for these services could work if they weren't piping a majority of profits back to the bloated mothership.

> A driver recently shared with me that he made $5 on a $23 ride I booked recently.

If I order Doordash, the food is already way more expensive than in the restaurant. The driver gets a delivery fee. The driver gets a tip. Somehow, a $10 meal turns into $25. And there's still not enough money to pay the driver to bring me food from 5 minutes away? (I'm blind and don't have a car.) Of course there is. It's just all going to corporate.

You thought Hollywood accounting was bad, wait until you learn about delivery business accounting.
There's a no-longer-very-speculative bit of Sci-Fi waiting here about whole societies "forking" based upon the curation of their training data. Arguably social-media + bots + paid state actors means we're already there.
This reminds me of Quaero and later Qwant. Both were French attempts to create national champion companies to compete with Google and establish digital sovereignty. Quaero totally failed. Qwant is still hanging on but nearly dead.
On self-hosted you can use the same as what cloud vendors are doing. Patroni or pg_auto_failover to manage single-primary + replicas. Maybe Neon to run an Aurora-like. CitusData... Azure did a lot around to get elasticity. Not easy to do the same. YugabyteDB on Kubernetes can be a cloud-native self-hosted solution
Author's experience with ChatGPT as a coworker mirrors my own with Copilot. It definitely helps with the white page problem when doing green field work. Its really great at generating config since there are so many examples. Its pretty good at predicting tests, especially once you have built up a few in a file. I bet most tests will be AI generated within 5 years, or companies will run AI analysis on code they do for coverage.

It's not very good at high level stuff. It will attempt to explain code, and generate very plausible explanations that often miss key edge cases or forget variables. You have to keep on eye on it to prevent it from missing things. Recently I was doing some basic offset sum math, and it would readily generate an expression for the summed offset that would forget a term or two.

Copilot you can also prompt using comments, which means I first express my wants in plain language, and then code. Its made me realize how much writing code is tied to my thought process, and trying to decouple them is hard. Also copilot can be a net negative. If you are thinking about a line, it may give you a completion. Now you have to think about the code in your head and the possibly wrong completion on the page. Like during pair programming, I just want Copilot to shut up so I can think.

My perspective on this is a little different because I ride a bike in NYC and I do not order delivery food, ever. Thus, I only experienced the negative externalities of these apps on cycling in NYC, and I don't care about delivery food becoming more expensive or whatever.

With the possible exception of the people that ride the new gray Citibike e-bikes, delivery riders are almost unquestionably the worst behaved "cyclists" in NYC. I put "cyclists" in quotes because half of them are just riding mopeds now.

- They ride in whatever direction is most optimal, one-way streets be damned. This is called "salmoning" and it is universally loathed.

- They don't even slow down for red lights half of the time. Look, I know, it's NYC, almost everyone Idaho stops or Idaho slow-rolls, there's even a proposed law to officially legalize it now, but they really take it to another level.

- They have no awareness when starting, they will just fly into a bike lane without checking over their shoulder. Also includes right/lefts on red (also not legal, but everyone does it, and it's pretty much fine if you at least check), they do not check for something riding down the bike lane with the light.

- Less relevant since it's summer currently, but usage of lights at night by these riders is maybe 50% at best. They also wear black a lot... so black bike, no lights, riding the wrong way in a bike lane. Fun!

- The mopeds. Mopeds are unambiguously banned on bike lanes and especially on the bridge bike lanes, but it's impossible to ride over one of the East River bridges these days without being passed aggressively by a gas moped, not even an electric one (which are still banned!).

I don't know if this will make them behave better. I don't see why it would, if they can still maximize profit by putting everyone else in danger.
How psychedelic drugs achieve their potent health benefits
This thread is like reading that someone is shocked that other people don't burn their beds every morning after they wake up.
It's not hard to to write significantly more robust software than what you get on a late '90s LAMP stack. What killed those forums was the constant upkeep needed to keep them secure. Most of that is historical baggage though. The software emerged in a time when the threat landscape was completely different, and things like data portability wasn't even a thing.

The problem that remains is spam mitigation. Bots are very hard to detect, and there really aren't any good distributed approaches afaik.
I only know Mastodon: There's a large LGBTQ+ community who don't want to be indexed out of concern for their safety (because, for example, there are small far-right communities on other instances looking to cause mayhem). The ability to be oneself online without worrying about getting brigaded, doxxed, or whatever, is a selling point. Indexing runs counter to that.

The Apple Maps integration seems to be most of what's propping them up these days. It's especially infuriating because you can only see about 2 reviews before you're prompted to download the Yelp app for "full access".

I thought Apple was supposed to be working on their own review system or switching to a different service, but I haven't seen anything come of that.

Veen, thanks.

The new title sucks, but it doesn't matter – the story is off the front page for some reason.
Email is shrinking, for sure, but there are still a lot of options and providers and if you're hard core you can run your own if you're willing to pay for a clean IP address.

Pretty sure Mastodon doesn't allow indexing because that can be used to brigade users and they're trying very hard to actively avoid creating the dogpiles that twitter almost actively incentivizes.
The whole workbench system is shonky, for my money. It ends up with a situation where arbitrary UI context switches are needed to jump from one bit of functionality to another, just because of the historical accident of who worked on which piece of code.

Using the Solvespace solver is an interesting problem: it would switch up the FreeCAD licence from the LGPL to the GPLv3. The FreeCAD folks don't want to do that: it's fine from a licensing point of view, but they don't want the additional constraints.
One of the main benefits of having a battery is backup power during outages. You can’t do that safely without adding a breaker between the utility and the house (to avoid backfeeding and killing linemen).

In California, touching a breaker box is at least $10,000, so to amortize the cost of the paperwork, you need to put in a multi kw system. On top of that, you need to anchor it to the ground somehow, so that it doesn’t fly around in 50-100mph winds (which will happen about once during the lifetime of the panels).

Portable systems exist, of course. You could get one of those.

Also, a multi-kw system isn’t physically that big.
33-46% of students in the local high school used LLMs in a text production task.

But presumably these shutoff when grid mains is lost.
I know next to nothing about these but a friend of mine was grumbling the other day about why can't he just use his electric car's huge battery to power his house. It sounded like a great thing? During the day his solar panels charge his car and at night it could power the house (to some extent). I remember him saying something like this is being trialled in Japan maybe? Anyone knows more about this?

It's one of those battles you can't win: Ask people to choose up front, new users balk. Assign a default, the existing crowd absolutely riots about centralization, and half of everyone doesn't even notice the change anyways.
I read a research paper which says LLMs don’t actually improve by training on the outputs of other LLMs. They only gain the ability to answer the specific questions included in the LLM output training dataset. Their reasoning capabilities etc. don’t improve.
I am generally not very supportive of restricting AI research via regulation.

However, I would support a mandatory disclaimer indicating that content was created using LLM. Consider it a “truth in sourcing” rule.

> prioritized the author's laziness over audience comprehension.

Is that even possible?

The audience - people in general - are very resistant to having knowledge/ideas shoved into their brains, and I don't blame them, 90% of it is crap.

Authors have to work very hard to overcome this. "Tell them what you're going to tell them, tell them, tell them what you told them", best advice I got on presentations.

If there was anything better the Powerpoint, short of "killing the unbelievers", it would probably have made a mint by now.

This is a completely different story. YugabyteDB is about transparent sharding and shard horizontal scalability. Every table is split into tablets. A tablet can be thought of as a shard but one still thinks of a table as a whole. Each tablet is replicated. Replicas can be placed in different regions, even in different computing environments. Want to run it across clouds or span the cloud and bare metal? Ignoring the cost and minding latency, why not. It’s still logical single database with whole tables. Want to put some rows in selected regions? No problem, still one logical table. Very different from master-replica architecture.

The most accurate/charitable interpretation of the content, despite the abysmal title, would be:

If users provide content for free, then a platform must allow users to consume that content freely, as in "as they wish", not "for free".

The author supposes that this is a fundamental social contract between users and platforms that needs to exist for platforms to work well. The author does not cite any evidence or examples or really even provide any explanation as to why this must be the case, they simply state it as a fact. Personally I find that, while thought provoking, this thesis is not obvious and needs to be defended. And so I don't find much utility in this short essay other than to state the thesis itself.
It's difficult to get large battery packs right. In order to limit the possibility of catastrophic runaway of the pack you have to have extremely robust inter-cell or inter-module thermal isolation and heat rejection. These features are basically non-existent at the handheld power bank scale.

It'll be interesting to see Anker enter this space of large batteries. Either they'll work really well and you'll see them quietly get installed in lots of places, or they'll be in the news when they have a series of runaways and light some balconies on fire.

That being said, a lot of the risk gets taken out with lower charge and discharge currents vs a vehicle application.
Yes! These won't be stored directly on chain, but I plan on using IPFS with the link stored on chain similarly to what some NFT platforms are doing.
In his most recent appearance on the Fragrance podcast he talked about no longer spending more than he has, as he's responsible for so many people's monthly paychecks.

Google absolutely does crawl quite a bit of Mastodon, but the community is largely against crawling and indexing so in many cases Google may be blocked.
