Redefining Human History: Scientists Uncover Advanced 1.1 Million-Year-Old Tools in China

A 10-inch-long handaxe from 300,000 years ago was found at an Ice Age site, revealing early human mastery over materials and tool-making. The discovery raises questions about knowledge transfer and social interactions among early humans, and highlights their resourcefulness in adapting to harsh conditions. This handaxe is a tangible link to our ancient ancestors' resilience and creativity.
Needed to add support for ultra-widescreens for my #Bubblemania mini project (see previous toots). Luckily, there's not much else required here than adjusting the camera's viewing angle (FOV) for different aspect ratios, a great use case for https://thi.ng/ramp, which provides linear & hermite "keyframe"-based curve interpolations. Keyframes don't need to be time based, e.g. here I'm using aspect ratios (from 3:1 portrait to 4:1 landscape) as key frames to compute the desired FOV... easy, peasy! :)
![TypeScript code snippet illustrating how to use https://thi.ng/ramp to compute FOV angles based on aspect ratio. Source code:
const ASPECT = WIDTH / HEIGHT;
// linear ramp mapping aspect ratios to field of view
const FOV = linear([
[1 / 3, 65],
[1, 60],
[16 / 9, 60],
[3, 50],
[4, 45],

Time for an #introduction on this account:
Hi, I'm aekis, I'm a nonbinary queer person from Germany. On this account I post about the things I do: I'm an #electronics engineer doing work in #kicad both at work and at home with a passion for all things mechanical, #metalworking, #cnc & manual #machining, #3dprinting and especially #toolmaking and machine (re-)building.
I post about my projects here and sometimes make videos about them which you can find on diode.zone & youtube, links below. 1/2
