I'm finally working on a new blog post: a rundown of the very cool optimizations I used to compute Advent of Code 2024 day 9 part 2 as fast as possible

I'm using TikZ to create the visualizations, which creates SVGs that have a nice academic vibe to them

A new one for me:

Someone has created a fake Twitter account for one of my side projects. It's filled with dozens of seemingly AI-generated posts trying to make it look like it's partnering with some crypto pump-and-dump website

Fascinating times we live in

I wrote up some notes about how I used constrained cubic bezier curves in the envelope generator for my browser-based synthesizer

They look and sound much better than the x^n function I had before, and I the math involved turned out to be very neat

It was a bit like using a hydraulic press to crush an empty soda can, but I never pass up an opportunity to use Z3

Some person or org has been aggressively scraping data from Spotify through an API of one of my web apps

I blocked their IP, and two days later they started it back up but some kind of proxy service that sends the requests from hundreds of unique residential IPs - lol

Don't tell them, but they're still using the python-requests user agent, so I just blocked them in a sneaky way at the application level instead

The scraping has continued for days since then, so they seem to not have noticed...

GCP has some killer products that really put it ahead (especially Cloud Run, BigQuery, and its giga-cheap archival storage with instant retrieval)

Azure felt so incredibly Enterprise-focused and convoluted, but I've used it the least by far so it could just my unfamiliarity.

Having used all three, here's how I'd rank the main public clouds (considering ease of use, features, pricing, etc.):

1. GCP
2. AWS
3. Azure

Honorable Mention: Cloudflare. It's prob. my favorite, but it doesn't have everything that a "fully fledged" public cloud would have

I'm moving away from using ORMs to interact with databases in my projects

As soon as you try to do anything even slightly complicated or outside of the most common patterns, you're stuck fighting against it and the ORM becomes an active detriment rather than a convenience

I know this is isn't necessarily a hot take, but it's something I'm reminded of over and over

It's the most leaky abstraction I can think of and causes other problems like making poor-performing queries very hard to identify

I really do love Mastodon and plan on x-posting everything important to Twitter, Bluesky, and here

I'll certainly follow back on Bluesky anyone following me here!

I've been working on a screen-space reflection impl for my 3D projects over the weekend

Every part of SSR feels very hacky. It's an extremely clever algorithm and can provide realistic outcomes if tuned just right, but I see the appeal in raytracing and more physically-based methods.

It's one of those things where there are a dozen params to tune and you have to get set them just right for your specific scene in order to get good results

I recently realized that my browser extensions and userscripts were adding 50+ ms of loading time to every page I visited - even when not doing anything

I went through and disabled all but those that I really need. Even 50ms can make things feel less snappy in my experience

I'm finally getting around to porting over the amazing CSG.js library (https://evanw.github.io/csg.js/) to Rust for use with my other geometry processing stuff

The basic impl seems to be working. These two cubes are fused into a single surface with no interior geometry

Just finished re-reading Permutation City by Greg Egan

Certainly still my favorite book of all time. The ideas it explores hugely expanded my perspective when I first read it during college, and now I'm finding myself unable to stop thinking about them all over again

A first for me, I've fixed an actual bug in Chrome/Chromium!

https://crbug.com/40686236 and https://crbug.com/40592236 specifically

I kept running into it while working with web audio and figured I'd try fixing it myself

Now I have to figure out their review process and hopefully get it merged

TIL that AVIF files are now supported by all modern browsers

I'm switching all the textures I'm using for my browser-based 3D work to use AVIF instead of JPEG

The compression ratios are just massively better, and features like noise synthesis really help avoid visible artifacts for certain kinds of textures
