Hey! I've been creating a #game #engine #framework in #vala

Its ECS based, and its called Veggies (eat your veggies!). 🥦

My reasoning for this framework is to have a game framework alternative to #csharp. I'm not liking the encroachment #microsoft has over #gamedev and #indiedev

The video is the well known bunny mark demo. Renders up to 16000 bunnies before being under 30 fps. Still needs a lot of optimization.

I'm taking ideas from frameworks like #pygame, #pine, #FNA and #excaliburjs

Continued thread

The other strimmer engine just needed a replacement fuel line, the original had gone brittle and broken.

The engine runs fine and is barely used. But the bottom half of the strimmer is missing entirely. The remaining tube is bent. Looks like it may have been left on the ground and someone drove over it.

Could get a replacement shaft and tube, but I don't really need a third strimmer.

Ideas? Make a really short strimmer for children? Attach an old propeller and use as outboard engine? Motorized flyswatter?

Maybe I'll just keep it as spare engine.

Fun fact: The shaft in the tube is a flexible one, so it works even when the tube is bent. I didn't know that.

Fixed one of the strimmers from the pile of mowing junk the neighbours gave me.

The fuel tank was missing, but a tank from the parts box fit. It needed a new rubber grommet in the fuel tank.

These things get fuel by pressurizing the tank, so two hoses go there, pressure in and fuel out.
If the grommet doesn't seal tight, the pressure leaves through the gap and no fuel is pumped to the carb.

There was even a brand new carb for it in the box, I guess someone ordered that trying to fix it.

Then I strimmed around the house, kitchen garden and back of the sauna until I found some wild strawberries there, which I rather eat than cut 😆

Free strimmer. Well, about €0.50 in parts invested.

Because of AI slop and confusion caused by (often well-meaning) Americans on international online spaces, I was unsure if the engine on my #GolfGTI had just direct or multi point #fuelinjection

Managed to snag an official VW workshop manual and checked with my own eyes, was pleased to see the CHHA engine in my car does indeed have the extra fuel rail and injectors in the intake manifold (this is good, as #petrol sprays over the back of the intake valves and keeps then cleaner, without it they are prone to coke up and require walnut blasting)

I do not know why Americans only get engines with direct injection (into the combustion chamber), whether this is simply cost cutting by #Volkswagen of #America or some other reason..

Vello, github.com/linebender/vello.

Vello is a 2D graphics rendering engine written in Rust, with a focus on GPU compute. It can draw large 2D scenes with interactive or near-interactive performance, using `wgpu` for GPU access.

The more I learn about Vello, the more I'm fascinated by the number of state-of-the-art techniques that are used. It's so rich.

‘Engineering marvel’ found in Scottish attic ‘one of three in world’

A rare #Victorian engine, one of only three on earth, has been found by accident in an #Edinburgh attic.

“Remarkably, this engine is the second-oldest surviving Crossley four-stroke #engine in the world and the oldest in Europe.

“Only two other examples exist, the oldest is housed at the Henry Ford Museum in Michigan, USA, and another in Denmark.
