   Don't do that in C++. Maybe unless if you are debugging. This can blow up in your face in unexpected ways.

   You have critical section in the bonus section behind the pipe. Maybe shared state protected by that critical section could be your shared memory, like the state of the coins there.

   I stand corrected, not sure where I heard this then.

   AFAIK it records multithreaded applications on multiple threads and CPU, rr records them on a single OS thread, AFAIK. Not sure about replay. Never used undo though, so not sure how much better it is.

   > noticed how you encoded a flip (AB <--> CD) Exactly! There is also a less obvious relationship between A and B too: B is a A "backwards" (A rotated 180°, starting the curve from the opposite end). The strategy was to pu

   Found a space-filling curve for the wallflower: https://onlinetools.com/math/l-system-generator?draw=ABCD&sk... The previous one fills out the Koch island.

   The the arms of the author's "wallflower" fractal don't seem to curve, as opposed to the other, similar fractal (quadratic von Koch island). Which can be explained by each iteration adding a mirroring.

   Got a bit nerd-sniped by this and came up with an L-system that fills out (I think) "the wallflower": https://onlinetools.com/math/l-system-generator?draw=AB&skip... edit: On second thought, this probably

    Most streaming does some batching. If you stream audio from a live source, you batch at least into "frames", and you batch into network packets. On top of that you might batch further depending on your requirements, yet I would st

    I'm drawn towards nix because of home-manager and because it seems to be the only package manager and distribution of neovim plugins that does package signing and somewhat resilient to supply chain attacks.

    Something like that is heading into C++26 actually. Except the initialization is not to zero, but to some unspecified value (with explicit intention of not allowing leaking garbage) and allowing to trap. It's called "erroneous val

    I'm not trying to find an attack vector, I'm trying to find a threat model where relying on non-signed commits on master is insecure, but relying on commits signed by the github key is secure. If you are looking at and trusting gi

    Signing with the github key doesn't add anything if you can verify based on UI/API anyway.

    So Github attests that the merge was done on Github's side, but what does "commit came from a particular person" mean? Who opened the PR? Who is the author of the commits in the PR (can be impersonated)? Who are the "com

    Don't you get all those guarantees by just pulling from github? I guess it's nice that you get an attestation that you can verify offline, but it feels like a marginal benefit.

    But that doesn't make any difference in the way you have to address existing `char arr[4] = "abcd"` declarations.

    I either don't understand how the annotation would work on types, or what would be gained by it. What type would be annotated? A typedef to char[]? edit: Unless what they actually mean is annotating struct members , that would actuall

    The problem can occur in general if there is a greedy match within the regex: https://github.com/hanickadot/compile-time-regular-expressio... Although it looks like that this got fixed for simple patterns.

    I can no longer make outgoing connections on 465 and 586, which is annoying as that's how I used a relay SMTP server. Which is funny because they suggest to use an SMTP relay, and I already did.

    While mostly agree, they do have some questionable practices. Like pretty much guaranteeing a middle seat if you don't reserve one, except if you purchase "avoid middle seat" from the popup right before checkout. Or deliberat

    Stable API implies stable size, but not the other way around. If I have a vector class that is a pointer and two sizes and change that to a vector class that is three pointers then I didn't change the size, but I broke ABI. Any change
