👋 This page was last updated ~3 years ago. Just so you know. In the two years since I’ve posted I want off Mr Golang’s Wild Ride, it’s made the rounds time and time again, on Reddit, on Lobste.rs, on HackerNews, and elsewhere. And every time, it elicits the same responses: You talk about Windows: that’s not what Go is good at! (Also, who cares?) This is very one-sided: you’re not talking about th

Also, types Losing the thread Off to the race conditions You can't use an old map to explore a new world But not all is preventable I still get excited about programming languages. But these days, it's not so much because of what they let me do, but rather what they don't let me do. Ultimately, what you can with a programming langu

Why is my Rust build so slow? I've recently come back to an older project of mine (that powers this website), and as I did some maintenance work: upgrade to newer crates, upgrade to a newer rustc, I noticed that my build was taking too damn long! For me, this is a big issue. Because I juggle a lot of things at any given time, and I have less and less time to just hyperfocus on an issue, I try to m

A terminal case of Linux Has this ever happened to you? You want to look at a JSON file in your terminal, so you pipe it into jq so you can look at it with colors and stuff. ...oh hey cool bear. No warm-up today huh. Sure, fine, okay, I'll read the darn man page for jq... okay it takes a "filter" and then some files. And the filter we want is.. . which, just like files, means "the current thing":

What's in the box? Here's a sentence I find myself saying several times a week: ...or we could just box it. There's two remarkable things about this sentence. The first, is that the advice is very rarely heeded, and instead, whoever I just said it to disappears for two days, emerging victorious, basking in the knowledge that, YES, the compiler could inline that, if it wanted to. And the second is

Contents The Future type. We can leave our Box behind I'd like to think that my understanding of "async Rust" has increased over the past year or so. I'm 100% onboard with the basic principle: I would like to handle thousands of concurrent tasks using a handful of threads. That sounds great! And to become proficient with async Rust, I've accepted a lot of things. There are blue functions and red f

I want off Mr. Golang's Wild Ride My honeymoon with the Go language is extremely over. This article is going to have a different tone from what I've been posting the past year - it's a proper rant. And I always feel bad writing those, because, inevitably, it discusses things a lot of people have been working very hard on. In spite of that, here we are. Having invested thousands of hours into the l
