Burning money on paid ads for a dev tool – what we've learned
Have spent six figures yearly on ads, mostly for reach for the developer-focused diagram library GoJS (https://gojs.net)
> Each experiment will need ~$500 and 2 weeks
I would add a zero if you want serious data. I would also double the timescale. $5,000 over 4 weeks
I second the uselessness of Google Display, it might look like conversions numbers are good but they are 100% too good to be true. As soon as you look into them you find the sources are things like "ad from HappyFunBabyTime Android app". You have to ruthlessly prune daily for months to get anything real, and even then I'm skeptical of value. For a developer tool with very strict conversion metrics!
But I disagree on Google Search:
> Good for conversion, bad for awareness.
Before we were popular it was excellent for awareness. Post popularity its much more arguable.

Purescript bindings for GoJS
Creating the Halogen components would be simple enough if one takes inspiration from gojs-react. The issue is that there are no PureScript bindings for the GoJS types themselves, but GoJS does provide .ts.d declarations, which means I could use purescript-read-dts, but that library's maturity/usability seems somewhat ambiguous, according to an author's post from 3 years ago.

Ask HN: What is the most impactful thing you've ever built?
I built GoJS, which is one of the most popular commercial JS diagramming libraries: https://gojs.net
I built carefulwords, a very fast thesaurus and quote site for inspiration, used by... tens of people a day. Eg: https://carefulwords.com/gift https://carefulwords.com/solitude
I mostly made it for myself, me and my wife use it all the time. I am slowly editing down the thesaurus to managable size.
I built a 12x16 "Goose Palace" barn out of local pine timbers, which taught me timber framing, and taught my tiny baby who turned 2 years old while doing it that this is just the kind of thing that people normally do, build barns in their driveway. Some context: https://simonsarris.substack.com/p/the-goose-palace
Some photos of building it with the baby: https://twitter.com/simonsarris/status/1584169368203956225
I designed my house, and have been writing extensively about that. Maybe this is the most impactful, since photos of it are all over Pinterest and other sites, now. The first post on that: https://simonsarris.substack.com/p/designing-a-new-old-home-...
I am not sure what is most impactful. Maybe ultimately it is building my family.

Node-Based UIs
I made a pull request for GoJS (https://gojs.net)
I have been building this canvas-based graphing library since 2011, and it contains a good number of features around customization and interactivity that are not found in other libraries. It is commercial for non-academic use however.

Where I can learn how to do the following in React?
in one project we use konva, in another we used gojs. Any of them or some other library needs some training and introduce own limitations but it still way way way better than handing all the coordinates, calculations, routing etc on your own.

TypeScript is terrible for library developers
I am really surprised by this guy's opinion. I make GoJS (https://gojs.net/), a diagramming library written in TypeScript. The project began in 2011 and we converted it to TS in 2018. It's been a huge plus. The sole downside was the initial time it took during conversion, but even in doing so we caught bugs with incorrect input types, documentation mistakes, etc.
On our end, it enforces type safety better than the Google Closure Compiler. There has scarcely been a problem with type complexity that was not ultimately our fault. Just a couple minor things that TS amended later. For that matter the TS experience has only gotten better, generally.
On our users end, we can now give them a .d.ts file that's much richer and easier for us to produce to aid their autocompletion. And we can use that .d.ts file to ensure that all the methods we intended to expose/minify are getting exposed. The advantages with the .d.ts and documentation make it feel almost essential to me for library developers to consider TS.
TypeScript has only made debugging easier, much easier since it catches errors at time of typing unlike the closure compiler. The sole exception is that debugging is a bit slower since I have to transpile instead of just refreshing the browser. But I have tsc set to compile a relatively unminified version of the JS. But if the slowness gets to me, I can just edit the JS output until I solve the issue, and then carry those edits over to the TS. This has never felt like a problem, though maybe his library is significantly more complicated.
Feel free to ask me anything if you have questions about library design + TS.

Ask HN: How to quickly animate sketches and 2D diagrams?
GoJS might work for you: https://gojs.net
Although the focus of the library is interactivity and not setting up sequences of animation, but that is possible too.

It's always been you, Canvas2D
My livelihood has been primarily building a Canvas diagramming library since 2010 (https://gojs.net), if anyone has any questions about 2D Canvas use in the real-world I'd be happy to answer them.
roundRect is great. Though you don't need 4 arcTo in order to make a rounded rect, you can use bezier instead (we do). Their example is also 1% amusing because they set the `fillStyle` but then call `stroke` (and not `fill`). I'll have to do some performance comparisons, since that's the operative thing for my use case (and any library author).
text modifiers are very welcome. It's crazy how annoying measuring still is, especially if you want thinks to look perfectly consistent across browsers. Though the chrome dominance is making things easier in one way, I guess.
context.reset is kinda funny. Most high-performance canvas apps will never want to use it. For that matter you want to set all properties as little as possible, especially setting things like context.font, which are slow even if you're setting it to the same value. (Or it was, I haven't tested that in several years).
I'm sure most users know this by now, but generally for performance the fewer calls you make to the canvas and the context, the beter. This is even true of transforms: It's faster to make your own Matrix class, do all your own matrix translation, rotation, multiplication, etc, and then make a single call to `context.setTransform`, than it is to call the other context methods.

Turbo Pascal Turns 40
Processing (P5) had this: you can select any string of text in its IDE anl search for it in the docs, and if it's one of the built-in functions or constants it will open the associated static html page that came installed with the software, so no internet nor server required. And despite being offline you can still navigate the docs too. This feels a lost basic skill in static site generation these days.
It was the only creative coding framework that had complete, offline documentation like that at the time I might add. OpenFrameworks is still mostly autogenerated stubs for example.
IMO it was one of the things that gave Processing an edge in educational contexts over all alternatives. I was pretty sad to see p5.js not fully continue that tradition and require that you go online to read the docs, and that it's not a static website but that text is rendered with javascript when you open it (still complete and with examples though).

My Google Play Developer account has been terminated
I thought it could be funny to use the javascript version of it https://p5js.org/ in a web page and then wrap it in a Unity app, since Unity was and is the environment I use for making apps.

Repetition can make you loopy!: Intro to JavaScript Loops
In this last section, I'll be creating some visual examples to show how helpful loops can be. I'll be using p5js, a JavaScript library with functionality for creative coding. That being said, I'll try to give a condensed version of the functions being utilized in the following examples.

G9.js: Automatically Interactive Graphics
I was curious too, took a little bit of digging :)
"the original domain of [P]rocessing was proce55ing.net, so people used to sometimes refer to processing as proce55ing or P5 or p5 for short. they still do sometimes. p5.js is a reference to that."

Ask HN: How to teach a kid of 15 Linux and programming
> how do I get him learning programming in a fun way?
Processing / P5.js can be pretty fun to learn. You use a real programming language to create art and animations. With little code you can get a circle on the screen, then making it move, then following your mouse, then adding other shapes, then changing colour depending on some event… It’s conductive to experimentation and a way to gradually introduce concepts.

[OC] I created a simple, free waveform and genre visualizer for your top ten Spotify songs, a few samples below and link to the tool in the comments!
Then I used p5js to create the 'art' itself, really user friendly coding framework with lots of resources online! If you want to get into coding, that is a really great entry point with Daniel Schiffman's coding train videos on YT!
