Great game. It could use an explanation of the (+#) modifiers though. For example, does (+#) green just add +1 to your attacks, and (+#) red add +1 to each enemy attack? I was proudly rocking some (+#) red armor of treachery until I realize

I think static typing + solid IDE support is too useful to pass up, and that's what Kotlin has. But Kotlin also has simplicity that, for example, Scala doesn't. I tried Clojure after spending a couple months with Scala and giving

For fun, I've been working on a simple hobby web server in Kotlin that wraps Jetty: https://github.com/danneu/kog I think Kotlin is the statically-typed language I've been waiting for, especially with the tea

Clozemaster is great and has already become part of my daily drill. I noticed that my daily streak grows just from doing a single exercise that day. I recommend letting us set a point threshold (maybe low | medium | high) that we must meet

Now let's say you're in a route handler where the buck stops, and you need to compose any number of async calls, some branching on if-else logic and/or the results of other async calls. This is where the "just wrap it&qu

Extracting inline callbacks leads to indirection, especially if you're only extracting to avoid indentation. It doesn't make the code simpler or easier to follow. Promises and especially async/await let you read code top to b

Finally, an article to link to my girlfriend when she finds me eating ice cream at 3am. It's a stretch, but I'm easily convinced after 8pm.

I can imagine a (tragic?) sci-fi love story where a once-couple meets again thousands of years in the future. One of them opted to keep their memories of the other on every reincarnation all those millennia, but the other didn't.

I refactored the User.rb file of a massive, legacy Rails app with that classic save-the-world beginner hubris. For one, I thought I was helping out by alphabetizing all the methods. Ended up with a diff that basically scrambled all 100k lin

Growing up, my family would do a 24 hour drive to visit family in Pennsylvania, and my dad would get the Sega/N64 working in the van with an inverter for my sisters and me to play on this tiny 10in screen. I looked forward to the 24 ho

I'd rethink that. Every connection to the server closes, and whatever else it might be doing stops, because someone hits your syntax error? And they completely DoS your server by slowly refreshing the page? Surely the best practice is

Some interactions with 3rd party libraries (like rendering stuff, leaflet.js, pixi.js) fall along natural event-driven faults, like the game update tick finishing, something managed by Elm being clicked, that sort of thing. In these cases,

And you can inline if-statements with an IIFE when you need a little more space: {(() => { if (cond1 && cond2) return <div>foo</div> else ... })()} Though it makes GitHub

It's not much. On the Javascript side, the Elm `app` is like an event emitter where you listen for updates and send it data. var app = Elm.Main.embed(...) app.ports.gameState.subscribe((data) => ...) app.ports.tileClic

The cutting edge of front-end development has been arriving at ways to split business logic from layout elements for some time now. Redux, Om, Reframe, Elm, etc. They all amount to hooking up components to a state transactor where the busin

It's nice to fire up an old Elm app and be able to make changes immediately. Not just because of the compiler errors, but also because of its other limitations, like having your effects isolated via `Cmd`s and ports.

I used Clojure for three years before realizing that all of the dynamically typed languages you listed still have the same hard problems: making large code changes and reasoning about existing code. I also realized that in the real world, t

Yes, I run such websites. A paid tier is a surprisingly narrow business model. People aren't willing to pay for much, and not every website has such an explicit product. A lot of that is just conditioning, as people aren't used to

I meant that the code has to be deployed to a separate system. Application code that touches the file system is still deployed along with the application code. You might commit schema.sql into your application repository, but that's no

You're updating code that needs to be executed against an external layer instead of just the application layer.

Also, "working hard" is pretty meaningless without context, especially if we're going to talk about regretting it. For example, carving out some time at night for your side projects that might pay your rent one day vs. stayin

Well, hopefully an SSG is saving you time compared to just writing a quick crawler that saves each route of your local Express app into a deployable static folder. If you find yourself credentializing in the source of an SSG because it turn
