Speculation Control — The Linux Kernel documentation

>Quite some CPUs have speculation-related misfeatures which are in fact vulnerabilities causing data leaks in various forms even across privilege domains.

>The kernel provides mitigation for such vulnerabilities in various forms. Some of these mitigations are compile-time configurable and some can be supplied on the kernel command line.

>There is also a class of mitigations which are very expensive, but they can be restricted to a certain set of processes or tasks in controlled environments. The mechanism to control these mitigations is via prctl(2).

Book review: "A Thousand Brains" by Jeff Hawkins - LessWrong

Compressing and enhancing hand-written notes

The main trick here is thresholding in HSV space.

Author points at at the end that he still needed to tweak parameters depending on the set of notes he's dealing with. I guess coming up with suitable defaults based on how the notes look might be something that would add value to commercial implementations of this such as Office Lens.

Entelecheia - definition of Entelecheia by The Free Dictionary

This is part of the rules for /r/programmingcirclejerk, and I can say that it definitely had the (presumably) desired effect.

What Is A Tulpa? — Tulpa.io

"A tulpa is an autonomous entity existing within the brain of a “host”. They are distinct from the host in that they possess their own personality, opinions, and actions, which are independent of the host’s, and are conscious entities in that they possess awareness of themselves and the world. A fully-formed tulpa is, or highly resembles to an indistinguishable point, an actual other sentient, sapient being coinhabiting with the host consciousness."

Gosh.

On repl-driven programming - by mikel evins

The key part of this (at least according to mikel evins) is that you can stop at any point (and in particular at a stack trace), inspect and modify live state including code *and then resume*. Few nonscheme things can do this.

Weird machines, exploitability, and provable unexploitability

Provides a definition of exploitability in terms of finite state machines: when the real state of the system can not be mapped to any state of the intended system (or an intermediate state when transitioning between any two intended states). Interesting notion of programming as writing an emulator for the IFSM.

On Moving from Statistics to Machine Learning, the Final Stage of Grief – r y x, r

Really interesting take, via HN, of the difference between statistics and data science -- the former is focused on explaining the parameters, the later is focused on predicting the future. "The big one that made no sense to me the first time I encountered it back in 2017 is that data scientists split their data into “training data,” “validation data,” and “testing data.”"

Why Do Dogs Look So Sad? - The Atlantic

"A paper published today in the Proceedings of the National Academy of Sciences found that dogs’ faces are structured for complex expression in a way that wolves’ aren’t, thanks to a special pair of muscles framing their eyes. These muscles are responsible for that “adopt me” look that dogs can pull by raising their inner eyebrows. It’s the first biological evidence scientists have found that domesticated dogs might have evolved a specialized ability used expressly to communicate better with humans." This is quite terrifying.
