Usually when I see this from non-spam sites, it's not even pushstate, it's just some page that redirects as soon as it loads. So you press back twice and it goes back -> forwards -> back -> forwards. Disabling pushstate doesn't fix that, it just makes pushstate equivalent to a redirect.

MV3 still allows you to run content scripts, which can inject any javascript into any webpage. From there, you can do anything you want. You can steal passwords, tokens, show popups, redirect, ... etc. Preventing extensions from dynamically modifying network requests doesn't change that.

This is the first human-learnable weak solution for connect 4. Surely it can be improved.

Firefox has this ability by default and I find it very useful. And it will never get sold to some random person to be replaced with adware.

This only applies to sleeper car routes. You're on the traib for 2-3 days, mostly with no cell service. If you eat in the restaurant car, they will seat you with strangers. If you sit in the observation car, there's a bunch of other people sitting there too.

I tried p4merge a while ago and it didn't do it ubfortunately, still stuck copying the base and ours to seperate files and diffing them.

Mac is good at managing low memory conditions. Linux is not. When I was on Linux, if I hit 16gb ram used the entire system would freeze for minutes. I would have to go in TTY2 to kill something to get it responsive again.

Speed bumps suck for both the driver and passangers of the car and generate road noise.

They're saying one example of a reason someone could fake a video is so it would get found out and discredit the position it showed. I read it as them saying that producing the fake video of a cop being racist could have been done to discredit the idea of cops being racist.

fish lets you cd to a folder without 'cd' although you still need the slashes. I use it all the time.

    c $> pwd
    /a/b/c
    c $> dir1
    dir1 $> ..
    c $> ../..
    / $>

I wouldn't consider having good default configs and being feature-rich at odds with eachother. Ghostty is feature-rich but needs no config. There's no reason yabai needs to be so highly composable that it doesn't even have a hotkey listener by default and and instead points you to another piece of software that only translates hotkeys to shell commands and is no longer being maintained. i3 at least has a pretty usable default config.

New comment by pfg_ in "Zig builds are getting faster"

pfg_ — Sat, 04 Oct 2025 00:34:37 +0000

The reason to care about compile time is because it affects your iteration speed. You can iterate much faster on a program that takes 1 second to compile vs 1 minute.

Time complexity may be O(lines), but a compiler can be faster or slower based on how long it takes. And for incremental updates, compilers can do significantly better than O(lines).

In debug mode, zig uses llvm with no optimization passes. On linux x86_64, it uses its own native backend. This backend can be significantly faster to compile (2x or more) than llvm.

Zig's own native backend is designed for incremental compilation. This means, after the initial build, there will be very little work that has to be done for the next emit. It needs to rebuild the affected function, potentially rebuild other functions which depend on it, and then directly update the one part of the output binary that changed. This will be significantly faster than O(n) for edits.

How is it real if it only exists as a spec in a book? Is there a compiler? Is there an editor?

> If there was a service that detected "here's a word from our sponsors" parts of the video and removed them, that would be altering Content

This exists and it's called SponsorBlock. It automatically skips past sponsored segments. Debatable if that is altering content though

Youtube creators get access to watchtime stats which show a dip for sponsored segments. My understanding is that sponsor contracts typically don't ask to get access to that data though, instead they look at views and refferals

But it's not just good enough, it's optimal. It is equivalent to picking a random deck from the set of all possible decks assuming your random source is good. More random than a real shuffle.
