If you’re not yet totally sick of hearing me talk… part 3 of my interview on the ADSP podcast is up, where we talk about variadic templates, std::variant, and (finally!) some Swift: https://www.adspthepodcast.com/2024/05/17/Episode-182.html

2021 me did a quick temporary hack to unblock a critical feature.

2024 me just tripped over it in the dark and fell flat on his face.

2024 me is not amused with 2021 me.

It’s been about 15 years since C++0x Concepts were removed from the draft that became C++11. I sat down with Conor and Bryce to talk through the goals and design of C++0x concepts, and some of the similarities and differences with the C++20 feature that bears the same name. https://www.adspthepodcast.com/2024/05/03/Episode-180.html

I’m proud of my friends, former colleagues, and the students of Indiana University Bloomington for standing up and making their voices heard in peaceful protest. I’m also terrified for them, because Indiana has always been a deeply red state that shows serious fascist tendencies, and these (as-yet unconfirmed) reports of snipers on the roof of academic buildings is an unnecessary, dangerous escalation on the part of the state. Stay safe out there.

My more-than-a-decade-old Brother monochrome laser printer finally failed, so alas, I must replace it. With another Brother laser printer, of course. But this one has color! And was manufactured after AirPrint so I can print from my iOS devices. This is Progress!

Hello C++ folks! I've started a blog series aimed at C++ programmers who are interested in learning #SwiftLang. It teaches the breadth of the Swift language, but anchored in the features and idioms of C++. So if you know your Rule Of Fives and your SFINAEs and think you might be interested in Swift, I'd love to hear what you think. Part 1 is something you know of from C++ that Swift takes a bit further: value types. https://www.douggregor.net/posts/swift-for-cxx-practitioners-value-types/

Here I go building a personal website and trying to focus on content, and @twostraws dangles a shiny new static site generator to distract me.

Ah, lovely. The old “vector reallocates while someone is holding a pointer into its storage” use-after-free, because of course C++ has no notion of memory exclusivity. No one is smart enough to use this language safely.

#SwiftLang parameter pack iteration is so much fun! This feature is amazing because it takes something that feels like it should be complicated---if you've used C++ variadic templates, you know what I mean---and makes it straightforward.

An important engineering step forward for #SwiftLang WebAssembly: we've had Wasm in the main Swift compiler + standard library repository for a while now (merged in from the excellent SwiftWasm project), but CI for it was separate. Now we're getting pull request testing for Wasm + WASI, so we can ensure that it remains healthy on a day-to-day basis on main. This is one of the important milestones along the path to making WebAssembly an officially supported platform.

Saw my first Cybertruck in the wild today, and let me tell you… the pictures don’t prepare you for just how hideous this thing is. It’s just so awful.

Anything that a compiler allows a programmer to write, some programmer will have written, and you will discover that such code exists only at the most inconvenient time.

Finally landed the first of many #SwiftLang standard library updates to replace "rethrows" with generic typed throws: https://github.com/apple/swift/pull/69771. The feature has been a fantastic exercise in generalizing in place: it maintains the same behavior for existing Swift code, maintains the stable ABI of the standard library, and yet any Swift code that adopts typed throws will see typed errors propagate through the standard library in the natural way.

Yesterday’s coding journey involved making a ton of progress on a hard thing, and it started to work well on small examples… however, the way it fit in to the code base required some duplicate logic, and that made my implementation gross. So, now I’ll refactor all of the bits (fixing some little bugs found along the way), and take a second stab at the hard thing once everything is nice around it. This is coding at its most fun :)

An undetected leak caused me to get an astronomical water bill this month. The San Jose Water Company gave me the polite version of the middle finger, so now it’s on to file a complaint with the California Public Utilities Commission. Now I’m basically drafting public policy in my CPUC complaint: smart meters can detect and report leaks immediately, yet water companies have been slow to roll them out. Seems to me that water companies should bear the cost for water overuse due to undetected leaks wherever they have failed to install a smart meter. Right now, they just pass the cost on to the consumer. This policy is better for both consumers and water conservation in general in our drought-stricken state, because it puts a cost on not installing smart meters.
