   Love it! For getting Apple Health data into duckdb, I’ve used this in the past: https://github.com/dogsheep/healthkit-to-sqlite . (You can load the SQLite database directly in duckdb.)

   I can't recommend nand2tetris highly enough – it's a great crash course in computer architecture, operating systems, compilers, etc. but also it's just mega fun. A big part of the joy came from making up my own extra credit s

   (Author here) I don't see that in Chrome so had no idea that was happening – thanks for pointing it out! I'm not a fan of coding ligatures so I just pushed a change to turn it off.

    I built https://grephub.com for that. It doesn’t maintain an index so it’s not super snappy, but it’s good enough / better than you’d expect in many cases!

    Great article. We've just moved a large portion of our async jobs over from Resque to Que because of the huge benefits you get from transactional enqueuing and processing. Performance seems good so far, and if it really becomes an issu

    I'm working on CodeCube ( http://codecube.io ) - a pastebin that allows you to run the code snippets and see the output live in your browser. It's built on Docker. I posted an article about how I built it here: http:&#x

    This is actually something I'd quite like to do with CodeCube - it wouldn't be hard at all. Replace SSE with websockets, attach to the container's stdin as well as stdout, add something like term.js, and it'd work a trea

    For one, it's much faster. CodeCube also streams the output to the browser. Also, CodeCube is open source ( https://github.com/hmarr/codecube ).

    Very interesting. How exactly does the retry-later logic work? Does it just push the message on to a 'deferred' queue, that you manually process at your convenience? Totally agree with your last paragraph, introducing a message qu

    Another open-source alternative is Sentry ( https://getsentry.com/ ), which supports multiple languages and frameworks. A hosted version is also available. The Ruby support in Sentry currently isn't quite as good as the Python support, but

    Perhaps it wasn't clear enough, but the post pointed out that typing 'bundle exec' and explicitly using --path isn't necessary. Once you've added one item to your PATH, and two lines to your bundler config file, you don't need to think abou
