   I recently switched from Apple Music to Spotify and one feature I was surprised was missing was a notification on song changes. I built an app to add this feature and also the ability to control Spotify via the menubar. One fun emergent beh

   To understand basic notation like summations and matrix multiplications, I created Math to Code which is a quick tutorial to translate math into NumPy code: https://mathtocode.com/ Previous HN discussion / it was on th

   Based on the feedback, Math to Code now includes a Show solution button which lets you toggle a solution on and off if you get stuck!

   Thanks for the feedback! It now autofocuses when not on a mobile breakpoint. I originally had autofocus enabled, but on mobile it would cause the question to scroll off the screen before you had a change to read it which... wasn't idea

   Skulpt does support the Python 3.7.3 grammar [0], but it's a work in progress. I have it enabled here: https://github.com/vthommeret/mathtocode/blob/0d5f780be4f218... Is there something specific that did

   Good idea! I just added it: https://github.com/vthommeret/mathtocode/blob/master/LICENSE

   That's close, but basically you need to take the square of each element first, e.g. `m * * 2` [0]. This keeps the shape of the matrix while `m.prod()` returns a single number (multiplying each element together). So it should look somet

   Hmm interesting, thanks for the report! I'll see if I can set up some kind of client-side error tracker so I can investigate more easily in the future. It's possible that it timed out when computing the result — it evaluates the a

   Agreed. Particularly because NumPy has a mix of functions and methods where you need to balance parentheses. I'd like to more clearly show the answers / I originally didn't show what the test inputs (e.g. if square root is te

    Thanks for the feedback. I think I was being overly clever by trying to make the product example more complicated than just `m.prod()` similar to the `m.sum()` example, but as you mentioned I was fitting two concepts in one question — opera

    Thanks! Skulpt doesn't implement NumPy out of the box, but I'm using a library which is basically a shim / partial implementation of NumPy for Skulpt: https://github.com/ebertmi/skulpt_numpy It's fa

    Got it! I'm working to add a "Show solution" button, but I just published another hint for that question. Specifically, the syntax is the same as for summations "m.sum()" but with "prod" instead. Additiona

    Thanks for the feedback. This is definitely oriented towards beginners but also love some more advanced examples. Math to Code is open source, so if you can express a solution with NumPy you can easily add new questions / I'm happ

    Math to Code is an interactive Python tutorial (all client-side) to teach engineers how to implement math in papers. I was inspired to create it while taking the Fast.ai course and seeing Jeremy Howard share [0] how a "complicated&quot

    I plan to create a Show HN shortly, but I created an interactive Python tutorial to teach engineers how to read and implement math using the NumPy library, called Math to Code: https://mathtocode.com It takes you from basic func

    I also highly recommend Complete Vocal Technique. It breaks down the voice in a unique way that I think particularly appeals to engineers and teaches you how to re-create any style safely by using correct vocal support, vowel choice, mouth

    I’m also picking up deep learning with a focus on computer vision. Do the first lesson of Fastai’s Practical Deep Learning for Coders — https://course.fast.ai/ It explains that trying to use your own GPU takes a lot of ener
