Great post on the history and benefits of SmartOS, a distribution of Illumos. Also includes a comparison with OpenIndiana, another distribution of Illumos.
Not OP nor am I a Rust expert. I can speak regarding another technology: sockets.
I've been deep-diving into sockets recently. 2 weeks ago I had only a high-level understanding of sockets (learned from casually reading manpages, docs, blog posts, etc.). I decided to read as much as possible because I wanted to understand networking fundamentals, and after a week I learned enough to write some sockets code in Python and C. I know Python quite well, so reviewing the ``sockets'' library made more sense after my deep dive.
If you want to get better at technology A using language X, I suggest either reading/watching as much as you can about tech A, and build stuff with it in language Y. Then you can circle back to learning language X and you've already mastered much of the concepts around technology A.
I followed the exercises in this book coming up on a decade ago. It was I valuable to my growth as a developer. The author, OrangeDuck, has many worthwhile projects. If you are learning C, it's worth checking out their Cello project.
I'm only finally learning journalctl after years of using Linux, and what a lifesaver this would have been if I had only learnt it sooner. This guide is excellent; it is succinct and informative.
I learned a lot about Mudge by reading "Cult of the Dead Cow: How the Original Hacking Supergroup Might Just Save the World."
For anyone wanting to explore 90's security nostalgia, it's worth a read. For anyone wanting to learn where hacktivism comes from, it's worth a read. For anyone wanting to learn about how security consulting has evolved over the years, it's worth a read.
Mudge is a very cool and capable individual. I am slightly surprised that Twitter would ignore someone of his talent and respect, and choose to air their dirty laundry in this manner. It's as if they have no idea who they hired. That, or C-levels think they can outpay $$$ any PR against Twitter to control the narrative. Either way, if Mudge is whistleblowing, there's probably some bad shit going down.
I used this site to help implement some core utils in TypeScript for Deno. They never had all the features, but it helped understand the code paths, etc.
Even though I haven't met a Sublime user in a few years, it still must be popular since it's at v4. Last time I checked, Sublime was still proprietary, which is the reason I had skipped using it. I've heard Sublime has some useful features, though. If it's in their interest, I hope they decide liberate / open their source code.
