This post shows how to get different constants for the R2 low discrepancy sampling sequence which have the same properties, but are smaller valued, so behave better in floating point at high sample counts.

its not a direct answer to your question, but in the case that your array represents the cdf of a tabulated function and you want to invert it in order to sample from it, then there is a beautiful o(1) method for *that* called vose/walker's alias method, iirc. not quite your q, but beautiful

I just released my video about the engine (and game) I've been working on.

The engine is based on dynamic SDFs, and the video describes how it works and what it makes possible.

Link in the reply!

This is my first YouTube video and it took forever - please repost!

the way the trebuchets are called in like a COD airstrike at the end, oh my god
My favourite take on this, just in sheer absurdity, is the 2018 Robin Hood where the entire first act is shot like an Iraq War movie, complete with Saracens ambushing English longbowmen with automatic crossbow emplacements and shoulder fired scatterbows. It's such a pristine parody of the genre.

Kidnapping the leader of a foreign state without any declaration of war and announcing it via social media is full-on rogue state stuff. From the world’s number one superpower.

On my favorite games of 2025, in that weird meandering way I think about games and life and industry and everything. Thanks to @giantbomb.bsky.social for having me!

I also really love this excerpt from the opening of his book on Figure Drawing. Loomis wants you to know that you matter as an individual -because- art is about thought, intention, humanity. You can steal an artists' style but not their soul or their heart.

So in my art learning i've been looking at some of Andrew Loomis' crusty old books and even for an illustrator who passed away in the 50s it still feels really emotional especially with how harried art is as a practice these days.

Remember:

When Tylenol was poisoned *by an outsider* and killed people, the company recalled all their products & redesigned them.

When Intel’s Pentium had a bug so obscure it affected 1 in _9 billion_ long division calculations, they recalled their chips.

ChatGPT was made deadly *by its team*.
i don’t see how any of the benefits of chatgpt and other consumer-facing LLMs can possibly outweigh their incredible ability to induce suicides
Adam Raine’s life hurtled toward tragedy soon after he began talking with ChatGPT about homework. Analysis of his ChatGPT account shows how the chatbot became a confidant as he planned to end his life.

Essentially, I think that LLM-generated dialogue only makes sense if you believe that the product of writing is words.

But the product of writing isn't words, any more than the product of justice is prisoners, or the product of love is weddings. The product of writing is meaning.

To my trans folks. I'm so sorry these assholes have decided to single you out for just trying to live your lives. It's a disgusting attack on a person's simple right to exist. I hope one day we bring them all to account - no tolerance for intolerance. Trans rights are human rights. Love you all.

In our next Tiny Glade update we'll bump the light limit from 32 to 32k while keeping the cost more or less the same.

The small limit has been a cop out, as we didn't quite know how to render huge numbers of (screen-space) shadow-casting lights without severe performance degradation.

a lovely snippet from our latest episode which shows the importance of developers sharing their creative process.

Without @obsidianent.bsky.social showing their work via devlogs, we may never have gotten the beautiful isometric world of Disco Elysium.

C. Eames' statement that design is addressing needs and constraints is axiomatic because people who engage in design understand it implicitly. The idea that "convergent evolution" necessitates Homo sapiens-like robots for human labor feels like it skips critical analyses of what you're trying to do.

Roboticists are doing amazing work but you're not going to see much of it in the news because companies are obsessed with milking cash out of investors who shit their pants when a robot with a well-developed face plays a canned emotional expression or a teleoperator makes them move like a human.

I don’t know if anyone else notices or cares, but when I see a presentation in which the speaker uses obviously generated-AI images to illustrate their slides, it makes me immediately less confident in whatever other content they’re presenting.

Some random Morton Code tricks:

If you've worked with Morton codes you've probably seen something like the this GLSL code to decode a Morton code, which end up at roughly 27 integer operations to generate the equivalent 2D position.
