> And the problem here wasn't JSON in the first place anyway

Yes it was. They stored state in a huge JSON dump which ended up working like a zip bomb by the way they had to escape a string. This alone resulted in an exponential increase in memory that quickly became a problem.

Think about it for a second: would they experience this issue if they stored an in-memory stack per user? They wouldn't.

Heck, it seems that they could live with their JSON choice if they replaced '/' with any other inescapable character and converted it back to '/' when reading.
Not everything though. There are some books I've only ever found through antiquarian shops and private libraries (eg http://londonlibrary.co.uk/ ) which are of historical and cultural value but which will probably never be digitised. Unless I do it, anyway.

There's also a whole world of professional texts in law and other subjects which I've had to access by taking the £200 train down to London to physically sit in the British Library and read (and often, photograph). The more interesting the thing you're doing, the more likely it is that you'll need to venture to an actual library, often one of considerable age.

That's not even to mention the historical archives etc, indexes of which are held centrally but the materials are scattered all over.
When personal computers hit the scene it was like manna from heaven. It has always been a huge physical challenge for me to write. I have to expend an extraordinary amount of energy to keep my arm and wrist steady when writing. The result is barely legible at best. Torture.

Later when programs came out they let you draw perfect squares, circles, and lines, I felt we had finally ushered in a New Age. I’ll be happy if I never have to pick up a pen again.

People seem to miss that better filters it is not just about higher price, but also higher CO2 emissions - filters decrease efficiency of the engine since they take energy to operate, moreover the energy consumption increases nonlinearly with decrease of particulates size. There's definitely a point where better filters don't make sense any more purelly from CO2 emissions perspective.
I can't read cursive either

Aren't you making my point here? You can't read it, and I presume write it, but you're saying printing can't keep up legibly?

Cursive fixes that speed problem.
What's the intuition behind this?
Probably should have licensed it properly from the get-go then, they can and probably will just use old commits.
Yes food is a great example.

People will pay upwards of $20-$25 to have one meal made and delivered to their home, when really the total cost of the meal is probably a couple bucks.

And then people insist on buying expensive processed crap, when the same thing could be had for far less with just some simple ingredients.

People waste money daily on expensive coffees and sugared waters, when all this probably costs mere pennies to make.

Gross, but people buy it. And often happily!
If you have trouble with cramped fingers, try writing and steering from your elbow. Keep the pen in the same position in your hand without clenching and only move your elbow.

You can also consider the pair of functional equations as implicitly using a Taylor expansion
The wikipedia lists a law of cosines [1] for the Bregman divergence and someone in this thread posted a proof that basically showed the law of sines follows directly from the definition of the sine. So neither form an obstruction per se, but the generalized pythagorean theorem kind of just follows directly from the definitions you need to make to even be able to say what it means for a triangle to be rectangular.

It also results in dead weight loss.

For instance suppose the marginal buyer would spend $20 for a product and the producer can produce for $18 and the market price is $19, resulting in $1surplus to each party. If a $3 tax was put on the product, the transaction wouldn't take place.

So you went from $2 social surplus to nothing and no tax benefit.

Any arbitrary price distortions will result in dead weight loss or the overall social surplus to go down compared to no distortion

That all depends on how you count initial investment. Software for instance (and most intellectual property, which is the basis for much of our economies here in the West) has basically zero marginal cost, it's all up-front development cost. The tax rate would depend on how you amortize the up-front costs, and much accounting trickery/complexity would inevitably result.
I think most people here love tech. They just hate having to use / build tech in a toxic work environment. I'm happy you found a work environment that lets you fully explore your passion.

> What made human males finally abandon that zero-sum game and develop more complex societies?

I think it's magical mushrooms and religions.

- With religions in the west comes a systematic approach of dissecting things (e.g. from the beginning of natural philosophy to Isaac Newton and so on)

- With religions in the east comes more intense forms of poetry and arts (e.g. I always consider the Chinese language to be more "psychedelic" than English)

The human history has always been about psychedelics.

Most of these "problems" with email seem to arise from problems with the big online mail "clients", like gmail. I didn't notice Thunderbird in their list of email clients (I use Thunderbird).

I deplore HTML-formatted email anyway. The last time I had to generate HTML-formatted email, the main problem MUA was Microsoft Outlook; I didn't realize that the problem was that Outlook used Microsoft Word's HTML renderer (TIL). I've always hated HTML-formatted email anyway, so jumping through the various hoops to generate HTML email automatically was a real drag.

The article's focus on the wonders of AMP as a solution is scary. AMP is a Google-controlled technology, widely-despised. Making AMP the solution to HTML email looks like a way of tightening Goo's already-tight grip on email's throat.

[Edit] So now a properly-constructed HTML email becomes a multipart with a minimum of three parts: text/plain, HTML and AMP. I don't see this as a wonderful new world.
All your claims are baseless and untrue.
Nuclear was replaced with renewables while also reducing fossil fuel use [1].
Prices are so high because of taxes and a lack of subsidies. Market prices are lower than in France [2]. Apart from gas prices, having to save France from its nuclear energy crunch was another factor for the rise in prices.

Some thoughts...

On the connected question of why human societies accelerated their development over time (recently posted on HN) a couple of comments are pertinent (see [0] and [1]).

If one values the continued acceleration of human development (in all its expanding pluralities) then there is a strong case for something like Z-lib to exist for a lot of factual or science-generated information being available for everyone. For such texts, I would guess that what the library contains could lag behind the commercial publication front by 5-10 years without appreciable profit loss to the publishing companies, nor significant losses to the estates of individuals who created them. And taking away some of their back catalogue might actually reduce publishers' running costs... (Ask: Can anyone else on HN put hard numbers to this?)

The debate seems similar to the one regarding taxation vs. inflation rate rises. Governments are currently choosing to raise inflation rates because that doesn't impede trade flows as much as some potential friction coming from moving money through a government bureaucracy for some cause. The particular cause matters, but the choice is about efficiency in essence. The same with Z-lib, as I see it. A Z-lib type free digital library could raise global efficiency in all sorts of areas, but the argument will only pass if various forms of extortive-because-looking-very-obsolete-now old capitalist inefficiences can be demonstrated to be such. Lots of publishing companies are probably holding on to old titles that for them are already digital landfill in their archives. Maybe they just need to see that clearly.

The other catch is that the "for everyone" phrase implies a representative global stakeholder is needed for it to "get legal". UN.org/z-lib anyone?

I get things done just fine with Go. And all the code is very clear. With ruby it is not, and a lot of ruby programmers may have a feel about how things work, while they are not really. They just enjoy the syntax. The book "The Ruby Programming Language" which written by the creator or ruby (I forgot his name) is full of "unfortunately", unfortunately this works this way now, unfortunately that works that way now.

And people definitly chose ruby because it was cool. So what you said should be applied to Ruby, not Go.

Graphics or any kind of symbols. I tried this with an out of print edition of an economics textbook from the 70s: the scans were fine but I never found any OCR that could even semi-faithfully reproduce the equations, nor anything in a table.

It occurs to me that a place where scans and first-pass OCRs of this stuff are shared with the intention of version controlling the resultant epub would be handy, such that small PRs could be applied cumulatively and the result be versioned (and therefore referenced). That's considerable work and legal risk, though.
What you are describing is mostly about market prices. Market prices rose also in the rest of Europe. The biggest factor really are the taxes. The market price for electricity is lower in Germany than in France, still consumer prices are much higher in Germany.

Prices are sticky. There were prices that hadn't changed for 20 years. Consumers notice when prices change. In normal times, a small increase in prices can have a massive impact on sales.

But when every other price is changing it becomes easier to change your price. And so suddenly you get 20 years of cost increases in a single jump.
I imagine it is the same with Bitcoin as well, and also highly overpriced art, and casino gambling, and investments in startups, etc.

It's little coincidence that the last of these facilities is housed in Utah.

Around half of Utah's population are members of that church, so there naturally is a much larger pool of qualified cursive readers to select from there.

Dicker: Enlarge Your Docker Experience
Show HN: Supavisor – a Postgres connection pooler written in Elixir
hey hn, supabase ceo here

this is a postgres connection pooler. it’s similar to pgbouncer, but built with Elixir and specifically designed for multi-tenancy.

it’s still under development, but it’s at a stage where we can gather a feedback from the community and you can try it yourself. we aren’t using this in production yet, but aiming to deploy it for a subset of databases in the next 2 months.

We have the following benchmarks (details in the readme):

- Elixir Cluster maintaining 400 connections to a single Postgres database
- 1_000_000 clients connecting to the Elixir cluster
- Sending 20_000 transactions per second
- Consuming 7.8G RAM and ~50% CPU on a 64vCPU machine

supavisor can be run as a cluster or a single node/binary. It’s handling 90%+ of the throughput of pgbouncer on a local machine (running pgbench)

we will place this in front of all supabase databases. It will eventually be able to handle multiple types of connections: traditional TCP connections, and HTTP connections for developers who are connecting to Postgres in serverless environments using Prisma, Kysely, Drizzle, etc

the proxy will serve as a connection buffer while we scale databases: scaling up compute with zero-downtime, and for scale-to-zero - triggering a server restart when a connection is initiated

finally, i want to shout out to Jose and the Dashbit/elixir team. They were extremely helpful with the design & architecture. they have been valuable partners, and elixir continues to be an amazing language for tools like this and our Realtime server.
Joel Osteen is great at helping people give him money in return for absolutely nothing.

I think there are two issues at play in the current NFT space, both exacerbated by the get-rich-quick potential of NFTs

1. NFTs as ownership standards are not there yet. Even on ETH, there are significant compatibility issues between NFT minters and discussion about downsides of the diverse storage architectures and ownership systems.

2. Classical business is still in flailing hands mode when it comes to adoption of decentralized tech, be it collectibles or more serious stuff.

I am happy we are having a winter now and I hope this one will last a while so that the true builders in this space will get the time they need to actually sort stuff out, build much needed infrastructure and for traditional businesses to read up a bit.

When I look at the image with the dots, I feel that my eyes are using the ratio of black to white as a low resolution “feature” that my brain is acting upon. So is it that my eyes are mainly providing already scaled information, or is it that my brain is choosing that information as the most important thing to act on? When it comes to fast decision making (which herd to target for hunting, which side of the hill do I run down to escape this predator) I’d kind of expect that the brain is hardwired to act on low resolution information quickly and process more detailed information at leisure.

I think the same goes for neural nets. Numerical features are often provided in some scaled manner anyway (e.g. not “how many cents has this stock price fallen in the last second” but “what is the ratio between the price now and the price a second ago?”, or even “what is the ratio of the stock’s price change in the last second, represented as a number of standard deviations from the mean in this background data?”.

And then there’s the fact that a (useful) neural network isn’t linear to begin with (if it was, it’d just be a simple matrix transformation). Each layer has an activation function. None of those I’m familiar of are even remotely logarithmic, but e.g. tanh and sigmoid functions are more sensitive to small changes at values near 0 than values far from zero. Perhaps over many layers it kind of resembles something kind of logarithmic? IDK

There's no such thing as greedflation. This inflation was caused by massive money printing by the Fed of unprecedented proportions, used to fund the Treasury which went on with massive money giving helicopter money.

Blaming capitalism when the reason this all blew up was practically the biggest socialistic experiment is ridiculous.

It really is the death of capitalism, but not because of capitalism but because the single point of failure of central banks and central control are enough to bring this whole thing down.

This is actually infuriating seeing a bank trying to deflect the blame. This is the results of decades of banks getting breastfed by the Fed, and then the Fed finally exploding it all in COVID printing and failing to raise interest rates for a whole year of rising inflation with nonsense of "transitory inflation".

So much lies. If there should be social unrest, it's at the Fed and the banks.
That is true, but let me quote from further up in the thread:
