• Apache ECharts

  "Observable is obnoxious if you want to add a D3 pie chart to your Vue application and have to untangle calls to D3’s API from reactive cell values, which look like ordinary JavaScript, but are not, and will cause compilation and runtime errors when copied." Yep - as I wrote: "If you want to just blindly copy and paste d3 code, you may have issues with the docs being hosted on observable." If instead you learn the... - Source: Hacker News / 25 days ago

• Natural occurring molecule rivals Ozempic in weight loss, sidesteps side effects

  I'd imagine many nested named capturing groups may trip even the best automated system! I do like the solution though. I would've probably approached it differently, trying to first get the 'inverted' match (i.e. Not matching anything that isn't a currency like pattern) and refine from there. A bit like this one I did a while back, to parse garbled strings that may occur after OCR [0]. I imagine the approach does... - Source: Hacker News / about 2 months ago

• Visualizing Data Is an Art – We Should Treat It Like One

  Was looking for some mention of Mike Bostock and his epic odyssey into this space. For those who aren't familiar https://observablehq.com/@mbostock. - Source: Hacker News / 3 months ago

• Ohm: A user-friendly parsing toolkit for JavaScript and TypeScript

  I experimented with an Ohm/CodeMirror bridge that would map an Ohm grammar to CodeMirror classes for marks and syntax highlighting. It might be an interesting starting point for you: https://observablehq.com/@ajbouh/editor. - Source: Hacker News / 3 months ago

• WebGL Fluid Simulation

  I have a fork of this that inverts the light model from additive to subtractive and suddenly its like ink in water https://observablehq.com/@tomlarkworthy/ink. - Source: Hacker News / 4 months ago

• Ask HN: Most interesting tech you built for just yourself?

  Https://mathb.in/ I wrote this 11 years ago for my friends and myself who were going through a phase in our lives where we used to challenge each other with mathematical puzzles. The use of this tool spread from my friends to their friends and colleagues, then schools and universities, and then to IRC channels. Now it is the oldest mathematics pastebin that is still online and serving its community of users. Visit... - Source: Hacker News / about 2 years ago
