I wonder what it would take for AWS to lower their outbound BW pricing to something that's not insane. I'm beginning to think that the only feasible solution is changing the law.

I'm suffering from fatigue from all the political commercials in which every single Democrat apparently single-handedly reduced the price of insulin. As if government-mandated pricing were a good thing. If something is overpriced, somebody should jump in and take advantage of a business opportunity. If nobody is jumping in, perhaps the item is not overpriced. Or perhaps there is some systemic issue preventing willing…

insulin is off patent. anyone can in theory manufacture it, but the ROI is just not worth it even at the current prices. Manufacturing it is not easy, there are humongous amounts of regulations, you will probably need to do a couple of clinical trials too... so you end up with an oligopoly that are incumbents that nobody wants to challenge, and prices that are all aligned.

Interesting you should choose insulin, as it's made by ~3 companies, and 2002-2013 the price went up 6x, while the price of the inputs dropped. ISTR that right after that it went up another 3x to over $300/vial. Thankfully, I only needed a vial once every few months, it was for my cat.

drugs are not made without government approval or something. the FDA tells you what you can or cannot do.

As someone who's been working on a file upload service for a while, this is the only real way to download very large files on Firefox. The file system access API is a great way to write chunks of a file at a gime, but for now Firefox doesn't support it https://wicg.github.io/file-system-access/ https://mozilla.github.io/standards-positions/#native-file-s...

That makes sense, and their reasoning looks sound. Here's hoping the file read/write parts get broken apart from the rest. Thanks for the link.

It makes me uninterested in Firefox. I want webapps to be able to talk to files, but Mozilla thinks it's too dangerous. Even though we already have APIs to talk to the local filesystem, & the main difference is this one isnt hideously slow.

This issue is one of those that when people are screaming, why are folks using chrome, why haven't we all switched to Firefox I point to and say, because I want a good web, I want a fast web, I want a featureful web, and Mozilla definitely does not share my priorities.

20MB/sec is 160Mbps, so wormhole wasn't that far off the 1Gbps. Sure not maxing out but within a factor of 6.

A factor of six is a very long way off, pretty much universally.

Yeah but with magic wormholes you see, there could be other universes where that's not the case and 160mbps is close to 1024mbps or 1000mbps whatever the cool kids call a gigabit now adays.

I don't recall where I saw it (either the Python or Rust implementation, most likely), but there was talk about trying to turn this into a browser plugin. I would love to be able to use my browser to send files to someone else (via their browser, if they so choose).

I don't know of one yet, but I tried to choose protocols (websockets) that were friendly to being hosted in a browser, or a browser plugin. The exception is the bulk-transfer protocol, that's pure TCP, which can't be used by plan web content, although I think browser plugins might be allowed to. The upcoming Dilation protocol should be more flexible on this dimension.

> The codes are short and human-pronounceable, using a phonetically-distinct wordlist. The receiving side offers tab-completion on the codewords, so usually only a few characters must be typed. How does this work from a security perspective? Given the lack of apparent entropy can’t a malicious actor conceivably enter the correct phrase before the good actor?

The PAKE algorithm lets you spend an interactive roundtrip to buy a full-strength key out of a weak shared secret. An attacker can attempt to guess the passphrase, and their chances are non-zero (one out of 65536 with the default configuration), but when they guess wrong, the whole protocol shuts down, and the real participants have to start over again, with a new code. So the only way for the attacker to win is for you to restart over and over again until they get lucky. Kinda self-limiting that way :).

You cant make a p2p connection over a NAT without exposing a port on the public side of the NAT.

Go check out STUN and ICE. The best article I've found about NAT traversal is this article from Tailscale: https://tailscale.com/blog/how-nat-traversal-works

Except in insulin’s case all they did was cap out of pocket costs, meaning insurance takes up the rest of the bill…which means the rest of us pay for it - and worse yet, it effectively stops any pressure on those companies to lower prices. That’s both political pressure and market pressure. Why the hell would anyone care or use cheaper insulin now?
