I don't know how to do that with the built-in drag-and-drop API. With mouse or pointer events: 1. When I get the event, I update the underlying state , but leave the DOM element alone. 2. I can apply constraints to that state. To rest

I don't worry about it. I usually wait a few years before using some browser feature. I'm not writing a production app and I have no customers. If I had customers, then I'd be looking at what browsers they use and making a de

Oh wow, FidoNet, that brings back memories. :-) I still miss Usenet of old.

I agree, more should be written about Perlin Noise range. You might find this useful: https://digitalfreepen.com/2017/06/20/range-perlin-noise.htm... In addition to range I'd like to see the distribution

Thanks! The short answer is: no. The longer answer is: I'm not actually sure how to solve this problem. The second site, simblob.blogspot.com, is an actual blog. It's time ordered. It has posts. But the main site, redblobgames.com

Many of the interactions I'm working on aren't about dragging elements, but instead using the drag motion to do some action. I also had trouble getting the drag-and-drop API to work inside SVG elements. I think it's solving a

Thank you! I treat them as documents , with some interactive elements. I tend to avoid traditional animations because they're outside the reader's control. I want the reader to be able to pause, slow down, speed up, rewind, etc.

That's great to hear — thank you!

1. I use words for variable names instead of single letters like the textbooks do. I use "priority" instead of "F", "cost_so_far" instead of "G", "heuristic" instead of "H", "

This year I've mostly been updating existing pages in small ways (examples: [1] [2]). This week I've been fixing broken links, which isn't a good HN submission. I think the best candidate is https://www.redblobgame

During the ice ages there were huge ice dams along the Columbia River, and when they broke it was crazy. There are lots of neat formations in central WA resulting from the floods [1]. I second the recommendation for Geology Nick but some of

Tarjan's Algorithm can be used to find choke points, although I haven't tried it myself [1]. I think what I would try is Breadth First Search with multiple start points to calculate various metrics for the map [2] and maybe All-Pa

Client-side proxies were a great deal of fun. I started in 1997 with the idea that I could intercept java applets and inspect/modify the byte code. For example I scanned for "new Sound()" and created a gui frame with play&#x2

Agreed, having control over what you see makes a big difference. I've been using Twitter this way for several years and it's been nice ("Lists" feature and TweetDeck).

It's interesting to see many people here post about their blog being 20 years old. Was that the golden age of RSS? It turns out my blogs are also 20 years old (although my web site is older). My first posts[1][2] were not so interest

I haven't tried this yet but the configuration on https://www.digihunch.com/2022/11/key-mapping-on-external-pc... looks like it will run when the keyboard is connected.

Agreed. I do have that, but I also want to use the same keyboard with Mac, Linux, Windows. So far I've been switching keyboard configurations on the keyboard every time I use a different OS, but I'd like to move that to the OS s

I loved Distill! My own experience with interactive content (not through Distill) was that it was so much extra work that it was hard to justify, except as a passion project, so I wasn't surprised by their (permanent) hiatus.

Braitenberg vehicles are fascinating. The doll story reminded me that there's tech out there that is expensive and hard in a way that makes engineers happy, but there could be some other much simpler tech that makes the end users h

Wow, thank you for this! I got to see Dollhouse in late 1996( ). Having loved SimCity, SimEarth, etc., I admit I didn't "get it" when I saw Dollhouse. I had plans this morning but I'm going to watch these videos instead

It's calculating the graph distance from start node(s) to all other nodes. Although in theory it's Dijkstra's Algorithm, in practice I see people use Breadth First Search in roguelike grid worlds. The algorithm isn't lim

It's around 3% of my pageviews as measured by javascript (e.g. statcounter) but it's 15-20% of my pageviews as seen in my server logs. Now, we might say that the server stats are wrong. But it could also be that the javascript s

I think about this a lot. My site is now 28 years old [1], older than wikipedia or google or even slashdot. People still read the gamedev pages, and I still update them. Coincidentally, I was just writing some notes on this topic last week
