Keynote’s Magic Move is great - until you try animating code. I wrote about building smooth "Magic Move" code animations from first principles using TextMate grammars & Heckel's diff algorithm: rahulrav.com/blog/magic_m...

Passkeys have big problems: 1. Made the mistake of coupling passkey storage with the platform. I should be able to use 1Password but it rarely works. Even Walmart gets this wrong. 2. Lack of a reset flow. Can't log into my HSA account anymore. Always greeted with an NPE server side. 😭

``` Upon reflection, I've come to believe that quality software is not about how many features something has or how quickly it is built but rather how cared for it is by the designers, developers, and product people who work on it. ``` This rings very true brettcodes.com/im-done-using-ai

I built Warp — an open-source implementation of morph transitions (magic move in Keynote) for code blocks from the ground up! github.com/tikurahul/warp Lots of interesting algorithms along the way.

I published vibrance-0.1.0 on Maven, now with support for Compose for Desktop (JVM). The APIs let you mix colors yourself, or draw gradients as modifiers or Compose brushes. Next steps: refine the model training to improve some color transitions, better alpha support. github.com/romainguy/vi...

I have always wanted to better understand how frameworks like PyTorch do back propagation for gradient descent. I finally wrote my own implementation for a scalar valued type that can compute gradients from the ground up. Its ~130 lines of Kotlin. Remarkably capable now ! github.com/tikurahul/by...

Signed up for Deep Learning coursework; and as I am reading some recommended papers - I swear adjacent to a mathematical construct I think i know, is a rabbit hole that until now never existed. Oh, you want an integral on this marginal distribution; surely you must have heard of error functions. 😭

Sometimes what you need is a hybrid of an ArrayList and a LinkedList. (When your API allows adding things into a list like structure - think contextual data). BlockLinkedList that does exactly. Uses ART instrinsics for a fast reset and object pooling to minimize GC overhead.

I collaborated with @zacsweers.dev (who did most of the heavy lifting) to add automatic tracing for Graph bindings generated by Metro. If you are using DI, then you should be cognizant of it's costs. Metro automatically adds traces for all generated bindings when you enable Runtime tracing.

PSA: Starting Android Gradle Plugin 9.0 (or the latest stable version of R8): R8 will automatically optimize all Intrinsics.check* APIs in Kotlin automatically ! This should greatly help improve app performance (especially Compose given the large Kotlin library API surface).
