I found https://www.youtube.com/watch?v=a_rAXF_btvE to be more balanced than the LTT video, but I think it mostly depends on your expectations of the cameras. The videos themselves are stored locally, not in the cloud. But if you have thumbnails turned on in the notifications, then the thumbnails have to be stored somewhere temporarily (I think this is an Apple/Google requirement), and they're being stored on a cloud server rather than in your home network (which would require opening up a port).

Slug preserves the vector shapes. MSDF first converts to a texture, which can lose small details. How much depends on the size of your texture and the complexity of the font. I expect MSDF will never look better than Slug.

However, MSDF can handle lots of distance-based effects (glow, shadow, outline, gradient, etc.)[1], and I don't think Slug does that. And MSDF is constant time whereas (I think) Slug is going to vary depending on the complexity of the font.

The Slug paper [2] says:

  All of the techniques that store data in a texture atlas are inherently using a discrete
  sampling of what is actually an infinitely precise description of a glyph outline. This
  inescapably leads to limitations that can be mitigated by increasing the resolution of
  the texture atlas, but that can never be completely removed. For applications that
  need to render a wide range of characters at potentially large font sizes, a texture atlas
  capable of producing glyphs at an acceptable level of quality may have prohibitively
  large storage requirements.

Thanks!

I originally had that near the top but in one of the rewrites I moved the papers to the end — https://www.redblobgames.com/articles/sdf-fonts/#appendix

Some of these banks are ridiculous. HDFC bank insists that I send them my photo id, address, phone number, and my Indian id number to prove that I'm not their customer. I tried explaining that I don't have an Indian id number because I don't live in India but they insisted they can't help me unless I provide all of this. Then they sent me legal notices threatening me for not paying "my" bills. I send all their stuff to spam now.

Also, emacs M-x from 1980 or maybe TECO's extended command from 1978 (learned these from Bobbie Chen who wrote https://digitalseams.com/blog/why-do-sublime-text-and-vs-cod...)

Nice interview! I didn't realize there was inspiration from Theme Park [1], a game from Demis Hassabis (DeepMind).

BTW in the next article the author goes into wind, evaporation, orographic rainfall, rivers, biomes. But not ocean current or tectonic activity.

There's a different blog series that does go into plate tectonics: https://frozenfractal.com/blog/2023/11/13/around-the-world-2...

Coincidentally Civ 7 just announced they're using plates with voronoi for their new map generator.

Love it! For typescript, esbuild has been my favorite tool for turning typescript into browser-readable js, and then I check type errors separately using the ide plugin.

I love having comments on my site/blog. I learn so much from some of them. For example, on my hexagon page, someone said there's a connection with "Eisenstein integers". I had never heard of them, and they were fun to learn about. Another example, I don't know "doubled coordinates" that well, so some sections of the page are incomplete. In the comments people have pointed to resources and code that fill in the gaps in my knowledge. Most recently, someone pointed out an inconsistency in something I wrote, and they were right — I have updated the page to resolve it. Before that, someone pointed to an emacs package that might make my life easier, and it looks like it will indeed partially solve the problem I had posted about.

I spend almost zero time moderating, because I've outsourced it to blogger/disqus. I'm not a big fan of disqus but the comments provide so much value to me, and disqus does the moderation so well, that I keep using it for now.

I think of it like giving a talk at a conference, and having questions afterwards. At some conferences, the questions are a waste of time. But at other conferences, the questions are quite valuable. I think comments don't work well on all sites. But they work well on mine.

Suggestion: canvas.addEventListener('dragstart', (e) => { e.preventDefault(); } );

At least on Firefox/Mac, sometimes while dragging it "picks up" the image to drag it. This should prevent that.

BTW this author also has a fantastic YouTube channel in which he live-draws geological diagrams with MS Paint https://www.youtube.com/@TheGeoModels

Agree. Weatherspark is great too — https://weatherspark.com/map?pageType=4&yearNumber=2025&ids=...

Each of those icons is a full year of weather data. Left to right is Jan to Dec. Bottom to top is the hours of the day. The pixel color tells you cold vs hot.

There's a version of Facebook that only shows things from your friends, and not "suggested" or "reels" etc.: https://www.facebook.com/?filter=all&sk=h_chr (it still shows ads but not the other random stuff)

And it doesn't scroll endlessly. It will display this at the bottom of the page:

With the older tree-sitter package[1], I was able to use it with the existing major modes. The new built-in emacs tree-sitter seems to be more ambitious, involving new major modes.

(author here) I agree, the `type` example could be done with regular expressions. In part 2 I'm planning to describe the real reason I was using tree-sitter here. I wanted to highlight certain combinations of operations based on the naming conventions I use in one of my projects. In particular, I want to catch a function call where a function named "x_to_y" has an argument with a name that does not appear to be an "x". However, while writing part 1 I realized that I could probably do that with a regular expression…

Cool!

A large part of the reason I'm using these other services instead of hosting my own is because of mobile apps + browser extensions.

Fantastic article! I've been trying to figure out antialiasing for MSDF fonts, and have run across some claims:

1. antialiasing should be done in linear rgb space instead of srgb space [1] [2]

2. because of the lack of (1) for decades, fonts have been tweaked to compensate, so sometimes srgb is better [3] [4]

Do you have advice on linear vs srgb space antialiasing?

I love this page. Thank you. I bookmarked it in 2018 but still haven't used it, doh!

https://wwwtyro.net/2019/11/18/instanced-lines.html is also nice.
