wolf550e··on Taking CO2 out of the air would be an expensive way to fight climate change
I don't know but I guess they don't intend to leak a lot from their own device/tank and once they have sold it to the pipeline they consider it "consumed". The idea is to capture the same amount of CO2 from the air as is in the methane that is consumed.
wolf550e··on Taking CO2 out of the air would be an expensive way to fight climate change
I very much hope Casey Handmer's Terraform Industries succeeds. It's the best case plan I'm aware of for dealing with CO2. Put carbon capture, electrolyser and sabatier style reactor directly next to solar panels, produce Methane, pipe it directly into normal natural gas pipelines, use it to produce fuel and everything we currently use oil for, so everything that uses this methane is carbon neutral.

wolf550e··on Starship's Third Flight Test [video]
Of course it will not maintain its shape, but the pieces that land will be large.

It's made of 4mm thick steel sheets, and the FAA disagrees with you.

wolf550e··on Starship's Third Flight Test [video]
Starship is huge and heavy and made of steel, it will not burn up on reentry, if it falls on a populated area it will kill people. They will not be allowed orbital trajectories until they demonstrate they can control the deorbit burn.

wolf550e··on Israeli group claims it’s using back channels to censor “inflammatory” content
The national / federal government is able to send agents and enforce its will on states / provinces. Israel was not able to send anyone into Gaza.

It would be a "breakaway province" situation, except that:

a. Israel intentionally got all its citizens out of that place and

b. Israel had no intention of taking control and forcing Gaza to join back into Israel.

Israel mistakenly thought Hamas was transforming into a national government that is busy governing its territory.

Gaza was mostly an independent country at war with Israel and not even a little bit an autonomous province of Israel. The war could not be resolved and so it was stuck in a state where Israel thought it prevented Hamas from bringing in heavy weapons but did not want to commit to conquering a city.

I think some people thought that after Israel pulled out in 2005, and Gaza became autonomous, it would become a normal independent country, and people still treat Gaza of 2023 as if it's the Gaza of 2005.

wolf550e··on Israeli group claims it’s using back channels to censor “inflammatory” content
Your point C is bad. Israel has a border with Egypt, Jordan, Lebanon and Syria. Israel tries to control its side of those borders. But Israel doesn't try to control whether those countries have sea and air ports. Israel very much tried to ensure Hamas in Gaza didn't have a sea and airport, to limit the weapons Hamas has. There was (and is) a blockade. Gaza was reliant on Israel and/or Egypt for bringing in food, fuel and electricity. If it was a regular independent country (albeit a small one), it would have control of its own sea and air port, and would be able to bring in heavy weapons from Iran.
wolf550e··on Israeli group claims it’s using back channels to censor “inflammatory” content
To me "occupied" means there is control enforced by troops on the ground. Israel didn't have any control of what went on inside Gaza.

Gaza was blockaded. Israel tried to control who and what goes in and out of Gaza (to try to limit the weapons Hamas has). But Israel had no control over what the Hamas Gaza government did in Gaza, how they spent their budget, what they built, what they taught in schools, what their military was planning.

wolf550e··on The Curious Case of MD5
BLAKE3 is faster than hardware accelerated SHA-2 because the tree mode used in BLAKE3 allows hashing parts of a single message in parallel (with SHA-2, parts of a single message have to be hashed one after another, and parallelism is only used in workloads where you process multiple messages at the same time).

wolf550e··on A data corruption bug in OpenZFS?
Imagine a torrent client (or http client downloading a file in parallel using HTTP range requests). It creates an empty file and then it has downloaded a 1MB of data to write at offset 100GB and wants to write it to disk. It does not want to pay the price of waiting for 100GB of zeroes to be written. The other blocks will all be downloaded and written eventually, all out of order. If the filesystem had an atomic operation to transform a bunch of (block aligned) files into a single file (like AWS S3 Multipart Upload), then sparse files would not be needed for this case.

People shit talk NIF because it's a very expensive machine to calibrate the Fortran code used to test hydrogen bombs without detonating them, in no way meant to advance fusion for power generation, that gets accolades for doing something that will probably not be useful for a useful advance in fusion.

wolf550e··on Guidance on implementing cryptography as a developer
It is idiosyncratic but it's not a bad recommendation, right?

AES+HMAC-SHA2 would be AES-CTR and you would need to handle the nonce yourself, and that's not great.

XChaCha is extended nonce, which should be safer. But there is no standard for extended nonce AES.

Filippo Valsorda wrote that he would like XAES-256-GCM/11 [1]

XChaCha looks like a good recommendation.

Because lacking key commitment can lead to problems, a scheme that also gives you key commitment is better [2]? So that's not crazy.

What does Google Tink do by default / recommend? What does Sophie Schmieg or whoever recommend?

SSTO is unlikely to happen, because every SSTO design becomes better when you modify it to be TSTO.
