This week we're back on systems programming with Hare. A C-like language for the ages. We talk to its creator, Drew DeVault, about what he thinks we can learn from the past 50 years of programming, and how we can build that hindsight into a new language that will last for the next 100.  In among all that long-term ambition we talk cover everything from error handling, typed unions and linear types, to metaprogramming and Drew's microkernel operating system. It's called Ares, and it is, of course, built in Hare. -- Drew's Homepage: https://drewdevault.com/ Kris on Twitter: https://twitter.com/krisajenkins Kris on LinkedIn: https://www.linkedin.com/in/krisjenkins/  A summary of Hare's features: https://harelang.org/tutorials/introduction/ Hare Community Resources: https://harelang.org/community/ SXMO Mobile: https://sxmo.org/ QBE Compiler Backend: https://c9x.me/compile/users.html Ares OS Source Code: https://sr.ht/~sircmpwn/helios/ OSDev Wiki: https://wiki.osdev.org/Expanded_Main_Page The Ares System [pdf]: https://mirror.drewdevault.com/ares.pdf #programming #podcast #harelang #qbe #microkernel
