• 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

  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

• Python dependency management is a dumpster fire

  I built a tool to help me do that: https://observablehq.com/@simonw/wrap-text-at-specified-width. - Source: Hacker News / 5 months ago

• Comparing AWS S3 with Cloudflare R2: Price, Performance and User Experience

  I've benchmarked R2 and S3 and S3 is well ahead in terms of latency especially on ListObject requests. I think R2 has come kind of concurrency limit as concurrent ListObject requests seem to to have increase failure rate when serving simultaneous requests I have a few of the S3-like wired up live over the internet you can try yourself in your browser. Backblaze is surprisingly performant which I did not... - Source: Hacker News / 5 months ago

• Foursquare Open Source Places: A new foundational dataset

  The top H3 cell will have ID 841ec91ffffffff; Go to https://observablehq.com/@nrabinowitz/h3-index-inspector and paste it in and you'll see that it's… Istanbul! Write another query to find out what the most common fast food places are in Istanbul… (Burger King and McDonald's, and it's not even close). Install the spatial extension and you can find all venues within 100 meters of you. Find all the Taco Bell/Pizza... - Source: Hacker News / 5 months ago

• Reactive HTML Notebooks

  So I've used Observable Notebooks for building interactive articles for a while now (my favorite https://observablehq.com/@mjbo/sydney-qms-panel-public-telephone-pairings). I wanted to see if I could replicate _most_ of the (reader's). - Source: Hacker News / 6 months ago

• Reactive HTML Notebooks

  > and Observable is cool, but strays from standard JS. The front end does but the underlying runtime is running just javascript, and the source code is basically javascript with some trivial macros which are fully captured in the MIT licensed acorn parser. Thats why normal Javascript debugging expression work perfectly in Observablehq. https://github.com/observablehq/parser. - Source: Hacker News / 6 months ago

• Shaderblocks: Block-Based Image Editing

  I wonder, where do SVG filters fall on the vector/raster spectrum? I really like that I can tune them hands-on in Inkscape (e.g. Fractal noise + displacement map), and then use it anywhere that supports SVG. A little demo from a while back with some interactivity: [0]: https://observablehq.com/@dleeftink/svg-workbench#options. - Source: Hacker News / 6 months ago

• Crafting Painterly Shaders

  Yeah, I just had to open twitter to be able to ask him if anyone suggested experimenting with the Symmetric Nearest Neighbor filter[0], which is similar to Kuwahara but works slightly differently. With a little bit of tweaking it can actually embed an unsharp mask-effect into itself, which may eliminate the need for a separate Sobel pass. I did some javascript-based experiments with SNN here:... - Source: Hacker News / 6 months ago

• History of Hacker News Search: From 2007 to 2024

  On the topic of Hacker News search… a useful trick that not enough people know is that you can take the ID of a story and use search to return all comments ordered by most recent first - great for keeping up with what’s new in a specific conversation. Eg for this thread the most recent comments can be found here:... - Source: Hacker News / 9 months ago

• Show HN: We leapfrogged traditional vector based RAG with a 'language map'

  This is literate programming! Why not just put the codebase in the wiki and not have two representations diverging. Why can't we have diagrams and links in code??? We can, like https://observablehq.com notebooks, it's a better representation for understanding. - Source: Hacker News / 10 months ago
