🚀 #Redis #8.8 is here, promising new data structures that nobody asked for and performance improvements that everyone will struggle to notice. 🤷‍♂️ Because clearly, what the world needed was a revolutionary array data structure, not an actual solution to our contextually confused agents. 🙄

Arenas, Cyclic Terms, and Flat Equational Systems

I was invited a few months ago into discussions with Cheng Zhang, Sam Coward and Alexandra Silva on some work integrating loopy infinite streamy things into e-graphs. A few years back, I was barking up a similar but distinct tree https://www.philipzucker.com/coegraph/

Hey There Buddo!

RE: https://cosocial.ca/@rhempel/116650230030112969

For two decades I've been making that same point (below), also specifically for computational/algorithmic art. It's also been a key topic in many of my past workshops. More than just being about performance, data structure literacy (at least awareness of options) can be a powerful tool/help for expressing and actualizing ideas in the first place, especially for interactive situations (where using the right or wrong or no data structure can be a make-or-break in some situations).

Yet, most of the the time, I felt these efforts to encourage more attention on improving algorithmic literacy in the design/art world have mostly received disinterest or even active pushback (e.g. the classic "to learn how to drive you don't need to know how a combustion engine works" argumentation) etc.

In one of my roles last year, I was responsible for optimizing the performance of several art pieces by well known, celebrated "algorithmic artists" to allow their pieces to run at least with an "alright" frame rate on the company's chosen Android hardware (Snapdragon 8 based). Oftentimes the given code was extremely naive, unoptimized spaghetti and I managed to achieve 2-8x performance boosts. This is not to brag, but to illustrate the wider problem! If one's supposed expertise & claim to fame is "algorithmic art", then one should also strive a little (more) to become proficient in said medium. Good knowledge of data structures and at least a passing interest in performance & hardware are key attention points towards achieving that (in my view)...

The RAM and GPU price explosions will likely "encourage" a little more awareness in the future (not just for arty stuff)... Then again, mass slop coding is a strong counter force/movement... 🤷‍♂️

If crates were challenging each other doing yoga, Bevy would definitely be number 1! It is so incredibly flexible!

Just awe-inspiring!

Stacks With SplStack | PHP Architect

As developers, we have times when we get to process a lot of data. Sometimes it’s a few kilobytes of data and we don’t need to worry about the performance because computers are so fast. When we’re looking at gigabytes or more of data then we need to be aware of the performance of our […]

A sparse, compressed bitmap index in C. Is it better than Roaring Bitmaps?

https://codeberg.org/gregburd/sparsemap

#Programming #DataStructures #OpenSource

sparsemap

This is a C99 implementation of a sparse, compressed bitmap index. In the best case, it can store 2048 bits in just 8 bytes. In the worst case, it stores the 2048 bits uncompressed and requires an additional 8 bytes of overhead.
