When you write a recursive function, Lean’s kernel requires a termination proof, unless the function is a partial or marked as unsafe. In those cases, they can’t be used in proofs.…

Oh whoops, thank you for the correction! I didn't realize that.

The article says that AWS's Cedar authorization policy engine is written in Lean, but it's actually written in Dafny. Writing Dafny is a lot closer to writing "normal" code rather …

Try out Forker shorthand. You can learn it gradually, and the first steps are omitting vowels and simplifying some letters. You then progress to various abbreviations. Ultimately, …

One option for C++14 is the Au units library. Here's a comparison to other unit libraries, including mp-units: https://aurora-opensource.github.io/au/main/alternatives/

“Graph” here means the directed acyclic graph encoding the causal relationships, not a chart of a distribution.

There are other benefits to Bayesian data analysis besides being able to handle limited data. There are problems with the outputs of frequentist analysis around the quantification …

I remember that there was a company that would somehow print out the 3DS photos in a way that they could be seen in 3D (probably with limited viewing angles). I'm sure there's some…

Here's an article from the SEI covering the problems with using Ghidra for malware analysis of Rust code. See "Binary Analysis Without Source Code" https://insights.sei.cmu.edu/blo…

Ok, here's a better article from CMU's SEI. See "Binary Analysis Without Source Code". > In general, the layout used by the Rust compiler depends on other factors in memory, so eve…

The use of Rust has particular implications for malware analysis: https://c3rb3ru5d3d53c.github.io/2022/08/malware-reversing-r... So yes, it's relevant.

With the mention of memristors, this sounds kind of similar to what Wolfram recently said about hardware for neural networks that can simultaneously be memory and compute: > But ev…

Flagged because this "secret" has been known since 2020 (the article has been updated to state this but kept the clickbait title)

It's worth noting that the paper was submitted in August of 2021. So perhaps it took a year to develop the methodology and get the paper ready for publishing. They did use separate…

"The training, validation and test data sets are generated without overlap from periods in sequence. Successive periods of 400, 12, 40, 40 and 12 h are used to sample, respectively…

Looks like two studies contradict that: https://www.psychologytoday.com/us/blog/open-gently/201802/a...

Ha, I did the same thing, and in Perl nonetheless! My poor boss. I guess he forgave me since we’re still friends! Edit: A good book: https://en.m.wikipedia.org/wiki/Higher-Order_Pe…

One thing that helped me with this was getting good quality pencils where I can use a minimal amount of pressure (a non-ballpoint pen also works). I also had to unlearn gripping th…
