I don't understand why Github hasn't solved this problem with pricing updates. My understanding is they are getting hammered with LLM generated code growing their traffic by over an order of magnitude. So why not rate limit non-paying users and charge for whatever scarce resource is being consumed that is causing them to constantly fall-over? This seems like a basic economics problem.

> Github’s servers are constantly on fire as their usage increased something like 50x due to LLM sloppers pushing large amounts of trash code

Which means they have a pricing problem. Rate limit non-paying users.

What’s controversial is that EU rules force censorship.

I'd recommend Obscura because it uses Wireguard over QUIC and it pretty good at avoiding these blocks. It's also open source.

Would you agree it’s strictly better than a single provider?

There is no perfect solution, but I would argue that a blind relay is very clearly strictly better than the alternative.

Actually the top talent wants to work at a company that regularly fires the bottom performers

>Satoshi ninja-mined in the beginning for themselves

completely and provably false

> This comment is peculiar - among technologists, for years the common refrain I’ve heard is “Bitcoin makes no sense but the underlying block chain ideas are very useful”.

That's because they have no idea what they're talking about. At a certain point you have to ask yourself why Bitcoin is worth $2T and no enterprise blockchain has ever taken off. How many years more of this trend is required to prove the "technologists" are wrong? It's already been 16 years.

And while I don't believe in appeal to authority, it's worth mentioning that I have been working in this field for pretty much my entire career and TA'd the first Stanford CS course on blockchains and crypto currencies in 2015. I very much know what I'm talking about and the people at Vanguard are blindly parroting what Deloitte and McKinsey are telling them about "blockchain".

one reason it's better money than Gold, there are no industrial supply/demand dynamics impacting its price. It's pure monetary premium

Network effect, first-mover advantage, and fair launch that did not pre-mine coins for insiders. It's the only "pure" one because it was first and honest.

stablecoins are useful but you don't really need a blockchain. you just need enough of a rube-goldberg machine to claim it's "decentralized". The most popular "blockchain" for stablecoins is Tron, if that tells you anything about why the technology itself doesn't matter

There is a general purpose ledger for business. It's called a SQL database

If tokenization requires a trusted party to issue the tokens (think stocks) then no blockchain is needed

"We do have a lot of interest in blockchain, the technology behind cryptocurrencies. We believe its application to a number of other uses besides crypto will make capital markets more efficient, and we’ve been actively involved in research to use blockchain technology."

The exact opposite is true. Blockchain "technology" is useless beyond its ability to enable Bitcoin - a monetary innovation. Using it for anything other than that is simply trying to find a problem for a solution. Crypto beyond Bitcoin is also largely useless beyond serving as a democratized casino.

Postgres 17 tremendously improves vacuum performance

> but I'm really confused as to why they always choose the most random obscure bank. Why not partner with a major bank.

Because major banks won't support startups looking to compete with them. Why would JPM, BoA, etc. service Mercury who is going after their SMB business banking vertical? Banking is a cartel in the US. The bank lobby makes it as hard as possible to compete with them.

This is why I love Phoenix/Elixir. You get all of this by default for free.

Neither Uber nor Wework were financial institutions with consumer deposits they were funneling away to a slush fund.

It’s because of cheap money flowing into Wall Street. The negative impact of ZIRP has only started to be felt.

“There are no public metrics on how many people use Lightning, so critics point at metrics such as node count, channels, and capacity, which have plateaued over the past year and thus give a false impression that Lightning's adoption may be stagnating or declining.

Our research shows the opposite, as growth in the number of users, transactions, and volume has been accelerating significantly over the past years.”

Both Dallas and Houston are completely unwalkable, so you’d still need a car or Uber when you arrive.

Yeah it was basically useless for an Elixir project I was working on. That will probably change at some point I’m sure.

This is spot on. I found myself using Fly for a project because it was super easy, not because I needed edge compute. TBH it's still actually unclear to me who needs edge compute? What apps require this sort of infra? It's not 99% of web apps right?
