Good question, would be interesting to see an exact timeline on both side-by-side (confirmed events, not reporting).

Something tells me that the timing of the Claude Code supply chain attack is not a coincidence ...

There's a really elegant solution using Geometric Algebra, that to this day is one of the most satisfying things I've ever learnt. Steven de Keninck outlines it in his 2019 Siggraph talk [1].

strong visual reasoning apparently, which is nice. still lacking native audio however. hoping for more companies to embrace the spirit of something like `gemma-4-12b-qat` for actual multi-modality (text, image, video, audio).

Nice overview.

> At this size, there's no way to have a distinct upper and lowercase [...]

3x4 is feasible. I've designed the MiniGent font [1], including greek letters, numerals, punctuation, math, currency, and emojis. Written a whole LaTeX typesetter [2] around it. While not perfect, I'm amazed by how far you can take it arranging just a few pixels.

I love this one! Thanks for sharing.

It's not about the bitset itself. It's about how to organize and think about your flags.

The small visualization grid is fantastic for debugging, and the `word:bit` structure lends itself directly to organize your data in categories and display them as such.

Nice, I like the colored output tables. Started tinkering with a small profiling lib as well a while ago.

https://github.com/gurki/glimmer

It focuses on creating flamegraphs to view on e.g. https://www.speedscope.app/. I wanted to use std::stacktrace, but they are very costly to evaluate, even just lazily at exit. Eventually, I just tracked thread and call layer manually.

If I understand correctly, you're tracking your call stack manually as well using some graph structure on linear ids? Mind elaborating a bit on its functionality and performance? Also proper platform-independent function names were a pita. Any comments on how you addressed that?

Very exciting. CLIP and latent space embeddings in general are such an intuitive to use and powerful tool. I'm using it in some hobby projects, from semantic image search in private collections, to trading card recognition among tenthousands of cards. Love to see more open source work from big players on this.

Well, actually does in a lot of cases. For example line intersections are completely branchless in PGA. Parallel lines simply give you the according point at infinity. Pretty kool!

I wrote a program to let a ball roll down the brachistochrone and compare it to other curves as my final school project some years ago. Might help some to get a better idea of it.

The company that made the video and builds those drones, Ascending Technologies GmbH, is developing high-end systems targeted towards industry and universities. As far as I know, they have the only triple redundant flight controler and their own gps, which in combination is one of the most precise solutions their is [1]. It compensates winds of up to 15 m/s on its own. Their technology also powers the upcoming Volocopter [2]. So as surely the consumer drones get better and better each year, their is something to be have for a bit more money, right? ;)

Adressing object avoidance. Intel and AscTec are ahead in the game ;) [1]. But I agree that this indeed will become more and more prominent and really interesting in the coming years!

"[...] Someday obstacle avoidance technology in UAVs will be like seatbelts in cars: You simply don’t start going without it!” [2]

New comment by gurkwart in "Ask HN: Why did multicopters suddenly take off?"

gurkwart — Fri, 08 May 2015 15:42:43 +0000

Around 2002 two german guys set the path for today's quadcopters. They built the X-UFO and developed the X-3D and X-3D-BL sensors [1], which for the first time enabled amazing control capabilities for the still rather unknown quadcopters [2]. This led to the first success stories and the market kind of jumped on the train. Media did it's job and here we are. Technology has advanced a lot since then [3, 4]. Better and smaller sensors and microprocessors. More sophisticated materials and design, production and marketing processes. This surely played a big role as well, now that consumer market UAVs and flying toys can be produced quite cheaply. Also various open source projects popped up and nowadays even beginners can build and program their own quadcopter and PID controller.

As for helicopter vs. quadcopter - The latter is much simpler to fly, especially with autopilots and control units such as the X-3D or today's AscTec Trinity. Also safety for consumer products is an issue, where quadcopters with their embedded propellers have the bonus. And its omni-directional nature of movement yields more freedom and fun, especially as a toy.
