Greetings I just switched the services I'm using to send out the newsletter. Hopefully there aren't any major issues. I don't foresee anything from the delivery side, but if you're planning on unsubscribing, please do so using the new emails going forward. I basically have two lists at the moment, old and new, and if you unsub from the old list using an old email, it's not guaranteed you'll be taken off of the new list. Of course there is a very small chance that I miss your unsub from the old list, and forget to update the new list, in which case you have my sincerest apologies. Just send me an email if that happens (although again, it's very unlikely). Also the website might not be updated with the latest issues for a couple of days (so the link for the "Want to discuss the issue?" won't direct to the actual newest issue). I'll get that fixed ASAP, although so far it's only been discussions between me and God, so I doubt it'll disrupt anyone. Here's today's issue. Generating relocatable code for ARM processors Published: 1 October 2021 Tags: compiler The ARM Cortex-M is a group of 32-bit RISC ARM processor cores optimized for low-cost and energy-efficient operation. One of their drawbacks is that unlike other processors, Cortex-M doesn't allow for Position Independent Code to be generated, a huge limitation when it comes to firmware updates. In this article, Pavel Loktev explains why this issue exists and how the LLVM compiler was modified to resolve it.

Seva Zaikov's article focuses on React and outlines methods for optimizing speed by looking at reasons for re-rendering, memoization, inefficient props drilling, some state hooks, context, selectors, and redux data.

Well that doesn't matter, because you can just read this series of interactive articles by Adam Greenwood-Byrne. Although shrouded in the guise of a tutorial, it's by no means a how-to, and Adam covers everything from bootstrapping to WordUp Graphics, all the while littering gems of knowledge along the way.
