Yeah, that's true.

There is also the people cost. If you’re a hobbyist you could argue those are zero or there is only some opportunity cost. But for a professional validator, SRE salaries dwarf the hardware cost.

Another reason that I’ve seen brought up is that miners aren’t so coordinated. Somebody will have to actually fork the code, remove the difficulty bomb, change the magic parameters to not interfere with the PoS P2P network, etc. Then they h

You can halt the chain with 1/3 of the stake though. In Ethereum, that would trigger an inactivity leak that eats away your stake until it’s less than 1/3 of the stake, and consensus can be achieved again.

I wondered about this for a long time as well. Exchanges, RPC providers like Infura, wallet developers, dapp websites, etc., wouldn't endorse such a fork, so it wouldn't gain adoption. It might still happen, but it would fail to c

With cloud egress cost though, moving the data to a low-cost region could be expensive itself. I wonder when it would pay off.

I guess the lines can be a bit blurry especially when the compiled code still relies heavily on dynamic dispatch, but V8 generated machine code for the target CPU, marked the page as executable, and then it would call that just generated co

This course is great. I took it in person a few years ago, and I’ve since recommended it to quite a few people who got noticeably better at technical writing afterwards. There is not any great eye-opening insight in the course, it’s mostly

One thorny issue that everyone using Nix on non-NixOS eventually runs into, is the need to set LOCALE_ARCHIVE. Getting rid of that impurity would be a big step towards "works reliably, everywhere", especially for development envir

Ah, I didn't realize it could do 1.54 now, neat! Last time I looked at the state of bootstrapping rustc in Nix and Guix, mrustc could only do 1.20-something, and you had to build a dozen rustcs to get to the current version. Does mrust

I enjoyed Heardle for many weeks as part of my morning routine. Today I was greeted by a redirect to the new Spotify version of it, which says “Heardle isn't available in your location...” :'(

Another reason besides platform support, is bootstrapping and verifiable builds. rustc can only be built by a recent rustc, so it is a pain to bootstrap from source if you don't want to trust a big binary.

The Merge has been a pipe dream for a long time, but at this point, the implementation exists. Multiple testnets have already undergone the PoW -> PoS transition. Some minor implementation issues came up that have been fixed. I'm pr

The & in &str is like the & in &[u8], str is like [u8] (an unsized type), not like u8. A &str is a "fat pointer" (pointer + length), unlike &u8 which is a regular "thin" pointer.

There are still good synchronous alternatives, e.g. tiny_http for serving, and just binding libcurl for requests, but I agree it is becoming harder to avoid async.
