Typo

Near the top you have that the integers are a field but they are only a PID of course

Rust OS serial driver post

https://github.com/WesleyAC/subatomic/blob/38a77cc5f8e7169b1688f3316a978baa34d418c3/src/console/serial.rs

Typo in http://blog.wesleyac.com/posts/elliptic-curves

For example, integers (Z) are a field, as are the real numbers (R).

Z isn't a field.

OS Book review

Write a review comparing OSTEP (Comet book), Dinosaur book, and any others that I read.

Typo: Double "to"'s

In this paragraph:

If you see evaluating the candidate's ability to to the job as the ideal for an interview, this also reveals many of the things that are wrong with tech interviews at the moment - I've never had an interview that tried to evaluate my ability to work in a team or prioritize tasks - both of which are probably more important to doing well in a software engineering job than being able to find anagrams in O(n) time.

You have two "to"'s in the first line. It's probably supposed to be "to do".

Z is not a field.

Switch to hugo

Faster + less work to keep a working env installed.

Recursive vs looped

Although it might be a cute name because it fits in with the name recursive center, the blocks have just been looped so they cycle around. In recursion I'd expect file header information to be included, or more generally it implies a level of nesting that isn't applicable here.

Recursion;
[[[...G... NU is not Unix] is not Unix] is not Unix]

Looping
GNU is not Unix is not Unix is not Unix...

kernel stacks post

Write a post about things that people mean when they say 'kernel stack' and why it's confusing.

Hyperlinks in Notebook rendered illegible

might be silly to submit as an issue, might not be the right place – this is the only way i found to put this out here. the links at notebook.wesley.ac are displayed illegibly:

no idea if that is on purpose and if this is the right place to post stuff like this. ¯_ (ツ)_/¯

Learning groups post

Postmortem on all of the learning groups at RC (and other places?)

Nit: the integers are not a field.

Your ECC for beginners post implies that Z is a field, but this is not correct. Integers mostly do not have multiplicative inverse’s in Z.

Bluesky post corrections

Hi! This is a fun way to post blog comments. Re https://blog.wesleyac.com/posts/bluesky , a few corrections:

• You're right that the web and mobile apps are currently closed source, but the server is open source, https://github.com/bluesky-social/atproto , with related backend code in a few other public repos like https://github.com/bluesky-social/did-method-plc . I think they hope to switch their PDS to be run by indigo eventually, but not in the near term.
• It's maybe semantics, but their funding isn't really VC style. Twitter took no equity stake in exchange for their $13M funding, so it's more like a grant.
• The company itself is a PBLLC, which is meaningfully different from a traditional private C-corp, and they've disclosed their governance structure. The board is three people - Jay, Jack, Jeremie Miller - each with 1/3 vote.

typo in second paragraph of post

This is very minor, of course: in the second paragraph of http://blog.wesleyac.com/posts/elliptic-curves, the clause beginning "but it's inverse" should be "but its inverse", since the pronoun is possessive, not a contraction.

Intro to robotics post

LQR Post

Fix integral calculation in control theory posts

Something's funky...

Integers are not a field

There you have it. Division is not defined for integers, although it is defined for Z modulo a prime.

Speed of pings is limited by factors other than speed in fiber

Excellent article, and great data collection.

I would only add that the speed of transit in fibers is the dominant factor, as you have demonstrated, but it is not the only factor. In between hops there is routing equipment that slows things down as a CPU determines which route to forward the packets.
