Tell HN: Anthropic's Claude is significantly better than ChatGPT
It seems to have slipped somewhat under the radar that Anthropic's ChatGPT-competitor Claude is freely available on Quora's Poe [0].

I've spent the last 3 hours with the model learning about Chinese history and culture, including getting recommendations for literature, films, documentaries, and first hand accounts of specific periods. Academic texts from the 1910s and niche foreign language films with only a handful of English reviews were offered without a single hallucination. Historical analyses were nuanced and contextual but highly factual -- I stopped cross-checking info about an hour in, but fabrications were again not an issue.

In addition and in general, and across several conversations on different domains, it exhibits a different caliber of reasoning. It can think strategically about business and markets, it can actually capture something of the essence of an author/poet's voice, and give highly thoughtful critical analysis of texts. It can follow instructions and grok things very quickly.

Beyond that, it has an ineffably human quality that doesn't come through with competitors. Discussions feel vibrant and dynamic, with none of the robotically dull tonality of ChatGPT. And I can't stress enough the difference it makes experientially to not always be second guessing the validity of the output. ChatGPT is great but the spell is broken any time it veers into its own imagined world, here the trust is seldomly misplaced.

I'm sure if you actively went searching for shortcomings or hallucinations you could conjure them, but this thing could be the backbone of a state of the art learning platform today.

You lose about 30% efficiency using "standardized wiring" with an inverter heat pump instead of a communicating thermostat, because running a heat pump at 33% power continuously instead of 100% power 20 minutes of every hour results in a COP about 30% higher.
> Session... but it does secure messaging well.

And it's got the best tag line ever: "Exchange encrypted messages, not metadata".

Something like Signal, with this amazingly sad paragraph opening in TFA:

"Signal asked for my phone number..."

simply cannot compete with Sessions' tagline.
> I don’t understand. If you hold a bond to maturity you get it’s NPV. Valuing it at NPV vs mark to market has more to do with your plan than any sort of fundamental truth - they’re both legitimate ways of valuing it.

Correct. So, if you have customers and you put THEIR money into a bond and say you're holding it to maturity, but then your customers want their money, what exactly was the plan?
>decided to go the conservative way and buy bonds.

Just because government bonds are unlikely to default, that doesn't make acquiring them "conservative". If you're a bank, with an entire function dedicated to making sure that assets match liabilities ("treasury"), and that ought to be aware of things like "DV01" and "duration risk", then you're supposed to know this.
> If you're going to classify passwords as security through obscurity

Sorry if this wasn't clear. I was trying to adopt your apparent definition to point out that, passwords and authorizing-links can have identical functional forms. Both depend on maintaining the secrecy of a specific piece on non-design / non-implementation knowledge.

To make this clearer, let's say that your document's authorization link is determined by hashing the document id. If you don't use a salt, then the security of the system depends on the obscurity of your choice of hashing function. If you do use a salt, then your security also depends on the secrecy (and strength) of the salt value.

Since the issue in this case wasn't people reverse engineering the means of generating links to uncover it, the issue was not a dependence on obscurity of design and implementation. The issue was that the users of the system were not aware or forgot that authorization links were a secret or confusion about what level of secrecy was needed for a specific link. This is why I specifically called out a possible design change to the authorization links that would reduce the likelihood of similar human error.

Edit: In general, "security through obscurity" is both a nebulous term and one that often doesn't mean use of obscurity of design/implementation a portion of the security stance, but rather an over-reliance on obscurity of design/implementation without other security measures, such as the use and careful management of strong secrets such as passwords/keys. This potential confusion makes me view the "security through obscurity" term as more of a buzzword than a specific security criticism.
How will you compete with Goodman/Daikin and needing lineset runs with usually high voltage work and panel upgrades that sometimes come with converting to a heat pump.

If you don't use 24V AC controls i don't think it would take off with any installers and you seriously limit and then hinder yourself needing way more customer support.

What refrigerants are you considering as there is more environmental stuff coming out killing 410A.

You will be competing against installers that can offer 10 year warranties (Bosch, Mitsubishi) without any of the backing of a large company saying parts will still be available and that is a big worry with start ups, at least when nest got bought you can still run systems without the cloud or could swap to any 24V controls system.

I used to be an installer but am out of the trades now and I think you'd kind of off the mark with your shortcomings to the current experience, the biggest issue you're gonna find is duct leakage and contractors skipping out on the testing and then the old vac n run and the new construction builders literally will want whatever is cheapest and gets them through the build fastest (80% gas single stage with a empty coil box is hella common)

I hope you have seen the variety of retro installs that will need to be done as there are still lots of oil burners out there.

Honestly i've almost talked myself into the idea that I should be working on this project. LMAO.

Please tell me you aren't going to rely on internet and at least use local RTD sensors at least.
>Someone wrote this, someone can change it, and anyone in the git log can be held accountable for what they did

Uh, not really, no. The whole point of neural nets is they independently discover novel and unexpected ways of predicting the probable answer.

>Enter CBDCs

Your sentiment is common, particularly among central bankers. It feels kind of by design with the current international economic trends, but at the same time this seems like a pretty natural course of events when you have strong central banks. No matter what they do, it's always their fault because they have so much power.

Solution? They actually don't have enough; now introducing CBDCs. I don't think there's an obvious stable alternative either. Tether is just waiting for the rug to get pulled on it.
It's to launder guilt. I'm not denying the benefit. It's "The Algorithm" (TM). Nobody can change "The Algorithm" (TM), we'll just have to live with it. Sorry, but you're on your own.

Yes, agreed, in addition to being utterly useless as an intermediate step between HN and the interesting content OP found, Mastodon is a bad product that doesn't scale.
> Risk applies equally to depositors. Apparently we all forgot that banks have risk, just less than our mattresses.

Not since 1933, in the US. Our financial institutions have been oriented around protecting depositors since then, and everyone knows it.

There is a long list of people who get to make claims on the assets of a business when it fails -- depositors, bondholders, etc. Shareholders are always in last place or close to it. Everyone knows that too.

This isn't the wild west. There are longstanding rules and institutions here.

Small suggestion for your preorder buttons: the gray/white combo doesn't have great contrast and might be perceived as being in a disabled state. I'd recommend black/white on light backgrounds and white/black on dark backgrounds to make them fit with the (very nice) industrial design theme.

Our building (Western Canada) has a heat pump system and it's very capable of keeping the apartment comfortable in all seasons as long as your definition of summer cooling isn't "like being inside a fridge". Great to see the tech being developed for mass adoption.
Safe is doing a lot of work here. Government bonds are safe from default. Not from changing value when interest rates change.
Because if US Bank was collapsing it's one of those "end of the world as we know it" situations. Like, people would be looking to short BoA and JPM if that was the case.
Technically flash memory storage would weigh more as a 1 (or maybe as a 0, depending), since it works by storing electrons. Apparently it stores something like 500 electrons [1]. My phone has 6 GB of storage, so if they are all ones that gives an extra weight of 2.50e-13 g, which is 0.0001 nanograms. Probably not measurable, though, especially since the large mass of the phone relative to the change in mass eliminates a lot of sensitive measurement techniques.

I'm not sure if RAM would have extra weight, as I know less about how it works.

Sorry if I made it worse, I really felt like people's opinions were being treated uncharitably, and I was trying to right it.
It is about improving the packing of grounds by breaking up the subtle clumping that occurs during grinding to reduce channeling where water finds an easy path so part of the puck is over extracted and other parts are under extracted.

If you already had perfectly even flow, it's not going to improve anything. That might be true with great equipment or a very forgiving bean. It might also be true if WDT isn't enough to fix your channelling alone so there is more left to fix. This leads you to watching slow-mos of your pulls and inspecting pucks :)
>> "Please do not warp my words."

You too?

I've been down this road. I'm not going to say anything that can convince you.

edit: You might want to consider not using the same rhetoric as folks who call people groomers for not wanting kids to kill themselves because they can't get treatment for their dysphoria. Reconsider your sources of information if you sincerely feel hurt by being seen in the same light. You are parroting propaganda.
SVB locking money they might need access to is the FEDS fault do I understand you correctly? Did they hold a gun to their head? I'm not saying they're doing anything different than their competitors, but that's a stupid excuse.

The only thing that's broken is the financial system. A customer should be aware when depositing money that that money might be locked away, and agree to those terms, and get a cut.

This is SVB gambling and losing the bet, simple as. Everything else is just a pathetic excuse, don't enable it.

Just look at the term "excess liquidity", that's newspeak. I expect the bank to have my 100$ the day I ask for it. I'm not a using bank because I want to, but if I store it under my bed I get to deal with the IRS. They make themselves necessary to live, then expect my deposits to work for them.
So ghettos?
You say it takes a run, but all it really takes is an aggregate change in deposit behavior.

Like, for instance, your disproportionate share of startup clients easing off the cheap loans you had been offering them, because they’re no longer so cheap, and instead drawing down on (or moving) the balances that you had insisted they keep with you as collateral. Trouble was brewing on both sides of the business, not just on the asset position.
Impressive that your demo on wrapping React (https://pynecone.io/docs/advanced-guide/wrapping-react) only downloads 2.2mb. That seems quite low for both React and your library. Promising tech!

I'm using the Sentry free tier and it is great. The main value is how to managed repeated errors. You can group different exceptions for the "same" error, resolve errors that have been fixed or ignore known errors until they occur to more users, more often or what have you.

If you are good about squashing errors you can make it very far on the free plan. Plus they have some burst detection built in. Just make sure that "expected" errors aren't just ignored in the UI, stop emitting them in the app itself so they don't count towards your quota (and it keeps your logs tidy).

I haven't been using their tracing or anything because their Rust SDK doesn't seem to support it despite claiming that it does (or I have set it up wrong).
You mentioned CO2 so I hope you're integrating active ventilation through an HRV or ERV. Integrated energy-efficient heating+cooling+filtration+ventilation is the holy grail for me.
what if I gave you a nice little language where you could easily define transforms on tables and explicitly specify 'a where a.key != b.key'. and a type system that would let you define null and all its various arithmetics.

sure, you'd say, but SQL already does all that

but you've have well thought out type construction, and a standard way of defining abstractions and transformations on data. maybe it would be general enough that you would be tempted to go full-on stored procedure and forget about having to juggle two languages and their interface

still no?
I feel like there has to be another shoe to drop here, this seems almost too good to be true.

> Alpaca shows that you can apply fine-tuning with a feasible sized set of examples (52,000) and cost ($600) such that even the smallest of the LLaMA models—the 7B one, which can compress down to a 4GB file with 4-bit quantization—provides results that compare well to cutting edge text-davinci-003 in initial human evaluation.

this is the most exciting thing. the cost of finetuning is rapidly coming down which means everyone will be able to train their own models for their usecases.

Looking for the contrarians on HN: what is being left unsaid here that people like myself and Simon might be getting too optimistic about? what are the known downsides that people in academia already know about?
My impression is that Sweden doesn't care about the credentials of its pension managers. These people don't even conduct due diligence beyond asking their finance buddies for their advice.
It's not about the demographic. It's about the consequences to the rest of the banking system. That logic of protecting the system from systemic risk has not changed since the FDIC was founded.

> just don’t have good risk managers

They had no chief risk officer for 8 months. They argued publicly against stress testing banks. Their complete absence of hedging guaranteed that time bomb that would have gone off now or later.
> Depositors who really had to could sell their bonds immediately at a discount.

How does this kind of thing function? I assume the bank pools all the money and buys various investment products. Is there just another wild level of abstraction where"you own X% of this investment product. Feel free to sell your share to someone else" ?
The question is, now that we have computers and money is just an entry in a database, why are banks even necessary for storing and moving money?

The whole small bank and big bank issue is moot. Technology has long solved this problem so the government could roll out a solution where no one ever risks any deposits, no FDIC is needed, and no bailouts are ever needed.
Elon is spending all of his time sucking the dicks of the hard right wing MAGA crowd. That's not a vision.
I am! But I feel like I'm already apart of 20 gazillion game dev discords and streams. Focus is a real drain doing solo game dev (using Unity to make a 2.5d platforming survival game). Good luck to you and your crew!
A lot of them are edgy underage children and don't know any better. They think that they have a dark sense of humor but really they've lived a life disconnected from those words, so they like the idea of pushing others buttons at no cost to their selfish existence.
You're right about switching everything over all at once. That would be a big step change in grid load! But large scale heat pump adoption is going to take a decade or more, and in the meantime we can work to build out the grid, and also on technologies that make load shifting more feasible.
Perhaps not unlike software dev and premature optimization.
Depositors aren't though, which is the issue. FDIC will cover losses that weren't actually insured (above $250K). The money doesn't come out of the "taxpayer" but instead from the banks, but guess from where the banks get money from?
IMO, while their use cases do overlap, LXC is more geared towards a user installing things while Docker is more geared towards a developer creating a ready to use package.

LXC creates environments, while Docker creates apps, is another way to say it.
I've been using it for +1 year now, love it.

I have only one complain: I tried everything to configure it to open in a specific position in the screen (top left corner), and for FSM's sake, It's impossible! (Windows 10)
That sounds like a security nightmare tbh.
Or, as the TV show Little Britain put it: "Computer says no"
Iirc SVB’s assets aren’t enough to cover all withdrawals, esp if sold now. FDIC is either taking of the risk or covering the diffs. Money has to come from somewhere.
Ultimately, RAM capacity is what makes old computers usable for light use, or junk.

There are still people using the thinkpad x61 (2007) today. It came with 512MB-2GB ram, but you can put up to 8GB in it. 8GB and a SSD is enough to comfortably run the latest Linux and Chrome and is pretty decent on such a little computer.

If it had a soldered 1GB it would be junk.

8GB soldered ram will make your Asus junk in 2039 (2023 + 16 years), but 64GB in the Framework has a much better chance of being usable.

Laptop manufacturers (and clueless crony reviewers) say that the ram is soldered to make the laptop smaller, but units like the Framework clearly show this is bullshit. They're just doing it to stop you from extending the life is old hardware.
"Is my girlfriend pregante?"
>> "... decided to go the conservative way and buy bonds."

Sure but they could have bought shorter bonds instead of a bunch of ten years, there's no reason to take so much duration risk.

Every intro to financial engineering class includes a "build a Treasury ladder" exercise, it's not rocket science.
VC portfolio companies don't need loans; that's what they have all that cash for. It's also why SVB had everything in treasuries because they couldn't loan it out.

Founders used SVB because of hearing things like how regular banks, if they see you have a failed startup in your history, might not give you a home loan. (And because it was trendy.)

I might pay your mortgage if comparable rents will cover it. There’s no guarantee that will be the case, and you could be stuck with a house you can’t sell or rent for more than the mortgage, taxes, insurance, hoa fees, hoa assessments, lawncare, gutter cleanings, pesticide, termite service and bond, replacement hvacs and appliances, roof replacements, exterior paint, interior paint, carpet, wall repairs, toilet issues, plumbing leaks, frozen pipes, squirrel and rodent damage, damage from tenants, vacant months, legal fees for evictions, and the risk of eviction moratoriums, earthquake damage, fires, etc.
From a Libertarian perspective why would we not:

1) have Congress+FDIC create a new form of deposit insurance that goes up to 10-25 million dollars[1] that is to be used for a new form of account legally dedicated to payroll; funded by a new set of fees since the private market clearly is not handling this issue well (Everybody knows about FDIC limits, and people who spend more than a fraction of time thinking about the risks can easily find out about third-party insurance and (newer) banking services that bundle your capital to multiple banks. )

2) impose interest rate stress tests against banks with much smaller amounts of capital (not the current $250 billion threshold which must mean only the top 10 banks are subject to it?) (Something that SVB lobbied to keep itself exempt from having to do, and avoided the expense of keeping its interest rate hedges up to date the last ~18 months, leading to their collapse.)

If you don't like one of those, then why not address a bit more of the root cause why businesses only do business with one bank:

3) require banks legally to not impose exclusive deposit conditions or benefits as a condition of granting loans (ie banks pressuring in any way their lendees to use their deposit services)

The recently revealed sort of moral-hazard/grey-area "backstop-all-deposits-but-only-for-critical-situations" is really anti-competitive if we don't address it. It ensures that startup/SMB business owners, unclear of whether their >250/500k deposits are fully protected or not, will want to move cash to the very biggest "too-big-to-fail" banks just so they don't have to financially architect around the cash flow risks. (Cash flow risks are the #1 cause of failure of small businesses.)

I would much rather have 1000+ banks in our ecosystem than 10; surely that is a more robust system.

To me, guaranteeing all deposits (not just 250/500k or even 10 million) is another form of moral hazard where banks "privatize the gains, socialize the losses"; But I think the payroll risk is a systemic societal risk that makes sense for us to develop a societal framework to protect.

[1] 250 employees at 250k each is a monthly payroll of $5 million. 6 months payroll is 30 million. If you're bigger than that, you have enough time/resources to put your eggs in more baskets and manage the complexity. I think I am being very generous here.
You'd think you would quadruple check that first.
Putting aside the glut of misallocated cheap money, isn't the deregulation that allowed this (which SVB pushed for, along with many other banks/Wall Street parasites) precisely the type of policy that Libertarians advocate?
At the time they were purchased, central banks around the world were going out of their way to assure people that rates would not be going up for a long time.

Not excusing their failure to properly account for duration risk, but regulators didn't see this coming either - what they were doing was considered to be not only wholly acceptable, but downright "safe".
I'm the opposite. We have to maintain a lot of different environments for different projects, and with conda things "just work" (esp now with better PyCharm integration). Venv is much more of a hassle.
