Enjoy traversing the wine dark seas. Planets now have fully simulated oceans that you can traverse above and below #gamedev

Personally - having Claude Code take care of fiddly vector & shader math and c++ boilerplate has made me ludicrously more productive building out my own engine recently

Would love it if agentic coding tools tip the balance back in favor of small teams writing their own weird bespoke game engines instead of using off the shelf options.

Some basic, but fairly convincing modelling of ocean waves. Should look pretty decent once I add in a proper water shader & some extra overlapping wave directions/frequencies.

Interesting data point re: AI use & software dev productivity. For the last 15 years my average Github contributions have been ~170 per year. This year (& primarily since May... I wonder what agentic coding tool got released around then...) I'm at 828

It’s a truism that whenever you think you’ve come up with an original sci-fi story idea, Philip K Dick already wrote a much weirder version of it in 1962.

Reading through this and the other docs I couldn’t see how you can detect when a model purge occurs (so that you know to start a new download and session). Would all the API calls for an active session start to throw/reject if the underlying model was purged? Or is there an event to listen for?

Been working on a prototype for a spaceship/aircraft building game. In this example I built a fly-by-wire stabilization system to make flying in turbulent conditions easier (you can see the elevons & rudder moving to counteract the acceleration shown on the yaw/pitch/roll gyro).

Set myself the challenge of hacking my old key operated pool cover so I can open it via web-app or HomeKit. After a few false starts and some burned out GPIO pins I succeeded www.sharpoblunto.com/News/2025/10...

Mamdani must explain his tweet from 1740 BC claiming that Ea-nāṣir had "high quality copper"

I also had it set to 'auto' which seems to default to dimming everything on startup & then slowly brightening up zones over time based on some brightness adaption heuristic. Turning it to off fixed the bug - so this time it was the hardware :) 5/5

Turns out I had 'local dimming' enabled. This setting on LED monitors tries to dim the backlight on sections of the screen with low light to try to enhance blacks, however my monitor obviously doesn't have enough dimming zones and... 4/N

I ran the graphics debugger & it showed that for a frame with the bug, the output colors were *identical* to a frame that looked correct. At this stage I was out of ideas & as a hail mary thought I'd look into my monitors settings to see if it was doing any postprocessing 3/N

I assumed it was the scene luminance calculation & adaption code as that does change exposure over time - however even with that disabled the bug occurred 2/N

You know the adage 'The bug is always in your code, never in the compiler/OS/hardware'. Well I actually ran into a hardware issue today. Working on HDR lighting pipeline in my engine the sun was appearing weirdly dim at program start, but would slowly light up. I looked for hours... 1/N

Rendering the phases of the moon in my pixel-art bonsai simulation. This is showing time sped up, in practice it matches the phase of the moon in your geolocated position. Check it out at vibes.pixelheart.io/#bonsai. #pixelart.

Love death & robots season 4 - LFG. Love the anticipation of an anthology show, which are going to be the Zima Blues & Jibaro’s and which are going to be duds.

Been working on some pixel art vignettes/simulations. They can render in both html and on a 64x32 led matrix hooked up to a raspberry pi. Might not be obvious buts it’s all very overengineered - IK solvers, particle systems, tracking the position of the sun & moon etc. lots of fun.

Built a new cherry blossom visualization for my lo-fi LED display (in addition to the existing fireplace & aquarium boxes I built a long time ago). The gently falling leaves, scrolling clouds & background audio make for a pretty idyllic final result

I think probably the fact that what we perceive as vast stores of knowledge and understanding are able to be frozen into LLMs so easily just means that a lot of what we think is different stuff is, in practice, really just redundant repetition of the same stuff with different signage.

basically everything good people want about the past is just because we lived so far beneath the carrying capacity of earths ecosystem so what if we just fucking ecomaxxed and biopilled and made the ecosystem so fucking sick it could just support 10 billion people idk
