https://youtu.be/_qaKkHuHYE0 (CppCon) A senior software engineer at Google tried to optimize tcmalloc by replacing a mutex with lockless MPMC queue. After many bugs and tears, the result is not statistically significant…
KCP uses a brute force congestion control algorithm that is unfair and inefficient. It is also poorly specified, which is probably why it is less commonly used outside circumvention circles.
From Steve Yegge: What really happened is that China hacked Google, and it pissed Google off when they finally discovered it, many months later. This wasn’t some small intrusion or data breach. It was a systemic,…
Sure, it's common to have it working for a long time, because breaking changes and interactions between different systems occur very infrequently at the level of bootloader and firmware, but when it happens it can…
I have used EFISTUB for 10 years but I wouldn't recommend it for the next install. The bootloader is the one arcane place that you don't want to be clever with and get reminded of its presence daily, because once it…
OK, maybe "Turing test" was a bad hint because too often its extension turns into a philosophical rabbit hole of defining intelligence. I want to get back to your initial statement about uncovering and structures, which…
The Heideggerian point is a start, but I don't think it's enough to just point out a failure like this. This allegation is something like "The answer is already encoded in the question" like of trick, similar to one…
Human can't visualize a tesseract, but human can conceptualize the Idea of a tesseract in the symbolic space, by math, physics, or in other words, by Reason. The Symbolic is a radically simplification of all the…
Plenty of RL systems learn to play video games just fine without fine-tuned rewards, but I see this line of thought isn't actually what you're getting at. I would assume serious ML people would not be overly ambitious…
These are all unified as different modes of message passing in probabilistic graphical models. Kalman filters are indeed structurally similar to an HMM without the backward message passing step if viewed as a PGM.
I find Yanis Varoufakis' account of the history leading up to the collapse of Bretton Woods very telling: As the combined costs of the Vietnam War and the Great Society began to mount, the government was forced to…
Can you comment on the tradeoffs between indirect TOF (phase) and direct TOF (time), what made Apple opt for direct TOF here, is it Microsoft's patents?
Why though? Realtime systems, games would love to disable exceptions.
Chromium's base, which is like STL but better and more feature rich, also with an excellent code browser https://source.chromium.org/chromium/chromium/src/+/master:b.... Also Google's Abseil, very modern C++ patterns…
I highly recommend doing some reading about Wallerstein's world systems theory and Kojin Karatani's The Structure of Empire, from which Jiang obviously drew his influence. If you think the global empire is something…
I stopped using it for locals after it increased my mental load. The maintenance cost of const for all local variables is huge during refactor like you're fighting it just to get things done. And in most cases where the…
Folds are not complicated. They are just not familiar to the intended readers. The changed version is idiomatic in image processing or similar areas that deal with pixels. Being idiomatic makes it familiar to read, and…
If you as a reader need const to make sure a local variable is not changed this is usually a symptom of this function being too long to see at a glance. And quite often as code changes I do need to make some local…
I love C++17 fold expression, but... Local consts are not particularly useful, especially for things like ints. Compilers know it's const, and a reader doesn't need to worry about it in a local scope. width, height…
Good writeup, but is there any mitigation for TLS shootdowns?
Is it correct to think of it as application code running as PID 1 in kernel space? Can I fork or create threads? Can I directly access kernel's internal APIs like a kernel module?
Recently I found out ebpf jitting will cause interprocessor interrupts even with all the isolation configs available today. There's probably many more places where such interrupts could be generated and not handled by…
It's all in the game, yo.
If you had the correct source you'd know the reporting system about pneumonia of unknown etiology you mentioned was not put into use until mid-January much to the disappointment of the official who boasted about it.
This is the kind of false argument being thrown around often in OSS discourse that ignores the structural power differential. Don't like it? Write your own/Leave. The fact is you can't go back to it as an individual,…
