Six ways to make async Rust easier
Asynchronous Rust is powerful but has a reputation for being hard to learn. There have been various ideas on how to fix the trickiest aspects, though with my focus being on Tokio 1.0, I had not been able to dedicate much focus to those topics. However, Niko’s async vision effort has recently started the discussion…

Not Explicit
Oftentimes when I am conversing about the design of Rust with other users - as on RFCs or the internals forum - I witness a peculiar remark about “explicitness.” It usually goes something like this: I do not like Feature Design X because it is too implicit. Magic is okay in Other Language Y, but Rust is supposed to be…

Rust: Structuring and handling errors in 2020 (2020)
After working through “the book” on the Rust programming language and getting started with the first non-trivial, real-world application I found myself faced with a question I didn’t yet feel well-equipped to handle: “How should you structure error handling in a mature rust application?”

Why Aren’t More Users More Happy With Our VMs? Part 1 (2018)

Brendan Eich on Ecma TC39, JavaScript.next, and Google Dash
I spoke at TXJS , a really excellent regional JS conference, in June. Thanks to @SlexAxton , rmurphey , and everyone else involved. My talk was concerned with the good, bad, and ugly of Ecma TC39 (and I mean those words in the best possible way!), mixing philosophy with historical events from the last 14 years.
