Holy crap, Swift was @clattner_llvm’s passion project he worked during evenings and weekends while having a day job managing 40 people? 🤯
Chris Lattner (@clattner_llvm) is one of the most influential engineers of the past two decades. He created LLVM, Swift, contributed to TensorFlow, and created the Mojo programming language.
What was the story about creating Swift - and why did he face resistance inside Apple when wanting to replace Objective C? What did he learn at Tesla, Google and CPU maker SiFive, that led him to working on Mojo at Modular? We cover these and many more in today's episode.

My favorite quote from Chris in this episode:
“I believe in the power of programmers. I believe in the human potential of people that want to create things. And that’s fundamentally why I love software is that you can create anything that you can imagine.”

Would folks be interested in a Birds of Feather at ISC debating/discussing different approaches to ISA design?
Alternatively could be a moderated panel in the RISCV Dev room at FOSDEM?

I am learning that I am an unusual CEO in many ways. Some know that I still code on nights and weekends (github.com/lattner) despite a busy “day job”.
As part of that, I care deeply about sw development as a profession, and what “AI anxiety” is doing to many early and experienced developers.
IMO, AI is here to stay, super useful today for things, and will continue to improve… but is far from SWE job displacement. It is sad for me to see many talented people giving up hope and sabotaging their own career development because of a future that may not actually arrive!
Please watch the video for a much more nuanced discussion about the issues involved, particularly if you are an early career engineer who wants to make a big impact on things!!
I spoke with @clattner_llvm about AI and software craftsmanship.
"The question is, when things settle out, where do you as a programmer stand? Have you lost years of your own development because you’ve been spending it the wrong way?”
A must read:

Working with @tlbflush preparing a massive Git monorepo (just like the UNIX forefathers intended!) to be open sourced for #riscvsummit
Should we do a 17-way octopus merge or is this aesthetically pleasing to y'all?

Users should always have control over their online experience.
Starting today, Firefox users can set Perplexity as their default search engine or choose it for one-time searches for intelligent, accurate, and trustworthy answers.

Microsoft just open sourced a Rust implementation of UEFI boot firmware called "Patina" this is a MASSIVE step forward in improving boot security for all. Exciting!!!
