Re:Incident with Github.com on Monday August 17, 2026 @10:05AM (#49331168)
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.
Re:Incident with Github.com on Monday August 17, 2026 @10:02AM (#49331102)
> 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.

Time lock encryption oracle that never sees your files and can be used in the browser or terminal with nothing to install (only curl and openssl needed). File encryption format is compatible across both browser and terminal.

Re:The Post-American Internet on Tuesday January 06, 2026 @07:21AM (#46511376)
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?
Re:Trust, 2-Party Relays, and QUIC on Tuesday February 11, 2025 @03:39PM (#43018060)
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
Re:No Bitcoin ETFs at Vanguard on Sunday January 26, 2025 @01:53PM (#42832761)

completely and provably false

Re:No Bitcoin ETFs at Vanguard on Sunday January 26, 2025 @01:35PM (#42832561)
> 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
Re:No Bitcoin ETFs at Vanguard on Sunday January 26, 2025 @01:25PM (#42832432)
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.
Re:No Bitcoin ETFs at Vanguard on Sunday January 26, 2025 @01:10PM (#42832261)
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
Re:No Bitcoin ETFs at Vanguard on Sunday January 26, 2025 @01:02PM (#42832161)
"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.

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.
