Some older PS1 games didn't work with the Dual Shock in analogue mode. You needed to press the button to disable the analogue sticks to play those games.

Right! Over the last 3 or 4 decades, our procedural and OO languages have slowly been absorbing the best ideas from "FP languages." We're getting to the stage where the very idea o…

Sure. I don't mean to say that imperative programming is going anywhere. If you're looking for programming languages with no support for imperative programming, Excel is pretty muc…

I agree. It's happening. Lambdas are now a requirement for any modern programming language. Monadic promises are how asynchronous programming is done. Rust is basically OCaml excep…

Further, these extra components are easy to omit if you don't want to use them. The REPL that we offer in the distribution doesn't include any of the analysis logic and it's just 1…

Luau also adds a continue keyword. It's probably the most troublesome thing you might encounter if you wanted to go from Luau back to Lua.

Be sure to turn the closed captions on!

Richard has a whole series of these. I was going to try to pick out one of my favourites from this series, but I really can't. Every last one is a treasure. EDIT: Oops! This is bas…

Luau already has some notion of nominal types to deal with the fact that the Roblox API is basically a ton of C++ classes that have been mapped over via the FFI. Some of these type…

There is a transpiler in the source tree, but I expect it needs a polish pass. We haven't put it to use in quite some time. In particular, I am pretty sure that it won't do the rig…

I did a little bit of GBA homebrew development back in its heyday. It is a really fun little bit of hardware to hack on. It's powerful enough that you can write your whole game in …

The right balance here can depend on the specific business you're working in. Some companies earn the privilege of a super tenured core team of engineers who work on their product …

I understand what you're saying, but something I have noticed over the years is that the amount of code that I can make sense of at any given time is actually proportional to what …

I switched to the Dvorak keyboard layout sometime in the early 00s. I've never owned a keyboard that was actually physically labelled for Dvorak, so I _cannot_ type if I can see my…

Most modern C++ code that I've seen restricts code to declaring a single variable per statement. It's not really a big deal because things are also always introduced at the latest …

Hello! I am the lead developer of the Luau type checker. I actually hadn't heard of Teal! I don't think it existed when we started. Judging from the Teal documentation, I'd venture…

Author here. :) It's Lu-au. It's like a party in your development environment!

I don't think many people would enjoy that at all. The appeal of games like Dark Souls (and Slay the Spire!) at high difficulties arises from the knowledge that you _will_ win if y…

I did a bunch of professional Haskell work in a prior life[1]. Most of its 'secret weapon' status springs from the way Haskell lets you control side effects. We had a fantastic uni…

If you are going to expect me to run your software in an always-on manner, I would greatly appreciate a native application. I frequently do light computing on a Surface Go. It's a …

The properties you describe regarding pure functions are correct and useful, but those ideas miss the point: Neither OO nor pure FP are required to build high-quality software! OCa…

The problem is the way the author instantly jumps from "98% pure functional programming doesn't work" to "you should use OOP." In order to bridge the gap, you have to make some pre…

The author seems to be implying that we have a hard choice ahead of us with no middleground: We can either accept object oriented programming, or we can turn to pure FP. The OCaml …

Nondeterminism is every place where information can enter your program from the outside world. It's random numbers, the system clock, data off the internet, and input events from t…

For what it's worth, I get the feeling that the reason TypeScript is growing so much complexity is not because the language designers expect you personally to use it all. It's ther…
