Up until ~2015 one of the world's most deployed browser engines was Sciter. A work of _one_ person. A fast embedded browser engine, a binary about 4Mb in size. It was used to render the UI in apps like our favorite McAfee antivirus. Th

I played around with it as a replacement for embedded WebKit in a desktop app. It's getting there! It's obviously not ready yet, but it's also not "infinitely far" anymore. I'm donating to them, because I think

One interesting thing about JPEG is that you can do some lossless manipulations with it. In particular, you can concatenate multiple images together. Unfortunately, no common JPEG libraries expose these operations. Your only option is to us

I have a 25GbE setup using Thunderbolt, kinda similar to the author's. Except that my fan is held together by a piece of string, not a 3D-printed enclosure. I found that SMB on macOS is just bad. If I try to heavily load it (e.g. by do

Modern elevators have regen braking, so they can recover most of the energy spent on going down. Older elevators used braking resistors for that. (BTW, going _down_ while empty is typically more energy-consuming for the elevators because th

I'm talking about the rate hikes in 2010-2011 after the economy started picking up. It caused the double-dip recession in 2012: https://www.macrotrends.net/global-metrics/countries/euu/eur... and https:

Look at outcomes, not just words. Bernanke made a correct prediction that the rate had to stay low and that it wouldn't result in high inflation. Meanwhile, the ECB started raising the rate once the economy stopped crashing. And that p

I made plenty of spontaneous trips. But even then I just need to pop into my garage, plug in the car, and it'll likely be close to 100% charged within 1-2 hours. Just enough time for me to get breakfast and read the morning YC news. An

Because there's no way to make that one connection that works well. IPv6 transitional state is fundamentally less stable than IPv4. If you mean that one connection should be able to use multiple address families and addresses, then yes

Happy Eyeballs was a bad fit for network-level implementation exactly because of sockets. But there's nothing inherently app-level about using multiple probing connections in parallel and then selecting the best one. If the IPv6 author

Well, yeah. And I also can do IPv6 without any of these new-fangled application-level TCP by using raw sockets. War story: many years ago I was developing a service that runs computational tasks inside containers. That was when K8s didn&#x2
257.
by cyberax 3mo ago
Honestly, I think that it is _the_ reason. IPv6 is a terrible protocol, but it could have worked. The problem was that the early IPv6 migration strategies all focused on getting IPv6 connectivity to clients as fast as possible (like 6to4).

by cyberax 3mo ago
Yes, there is. GAI was standardized in 2002, so it's not a part of the original sockets. And it still does not support Happy Eyeballs.
259.
by cyberax 3mo ago
That's theoretically true. But I don't know any public Internet-facing apps that care about that. For non-public networks, sure. For things like TCP-to-RS232 connectors that can only service one connection at a time. Happy Eyeball
260.
by cyberax 3mo ago
Nope. They have to be coupled for the Happy Eyeballs to work. Another option is for sockets to accept multiple addresses and address families in "connect" calls, so that only one connection wins.
261.
by cyberax 3mo ago
Raw addresses could have been an advanced option, rather than a requirement for every program.

You absolutely can establish multiple TCP connections for POST methods. You just can't send any _data_. This is even used by browsers, this trick even has a slightly creepy name: "Happy Eyeballs".

It's called a "loading dose" and it's a common trick in medication dosing. If your drug has an elimination half-life of 1 day, then it takes about 4 days to reach the steady-state concentration if you take normal doses.

by cyberax 3mo ago
PrEP is effective even when taken after the event. The approved protocol is to take a loading dose (2x the normal dose) and then follow up with regular doses for 3 days.

Yep, agreed. Garmins are great! I tried Fenix and I liked its feature set, but it's just too large for me physically.

Sockets won over over-engineered monstrosities like STREAMS or X.whatever And yet, sockets are a terrible interface. They don't provide a way to get the details of the underlying connection for features like migration, checkpointing, o

You can use TPM with secure boot to store the password. TPM checks that the firmware is the same and that the OS is signed by trusted (by _you_) keys, and if everything matches it makes the key available for reading by the OS.

Why is it round?!? WHY? Round watches are bad. A circle is the worst shape for watches. Good watches are not round. Roundness is an anti-feature. Really. Just use a rounded rectangle shape. It will end up _smaller_.
