"War for the Overworld" is pretty close to the original Dungeon Keeper experience.

Can't enjoy that without DK's wobbly affine texture mapping :-)

There were already parts in MSFS 2020, namely gauges aka everything in cockpit that had more dynamic display, that used JS based SDK in order to provide sandboxing and safe level of control over performance (because with sandboxes VM it's easier to preempt execution)

Also it allows playing Flight Simulator inside Flight Simulator :-)

What is?

dividuum · 3 months ago

I've build a custom thumbnail/metadata extraction toolkit based on libavcodec/libavformat that runs the decoding in seccomp's strict mode and communicates the results through a linear RGB stdout stream. Works pretty well and has low overhead and complexity.

Full transcoding would be a bit more complex, but assuming decoding is done in software, I think that should also be possible.

The conclusion of Davies' second extract — about e.g. being bumped off a flight — is recognisable but the conclusions are actually wrong. The situation in these cases is actually more subtle. The person you're speaking to does normally have some capacity to escalate in exceptional cases. But they can't do it as a matter of course, and have to maintain publicly that it's actually impossible.

The people who get what they want in these situations are the ones who are prepared to behave sufficiently unreasonably. This is a second order consequence of 'unaccountability' that Davies misses. For the customer, or object of the system, it incentivises people to behave as unpleasantly as possible — because it's often the only way to trigger the exception / escalation / special case, and get what you want.

After a quick search I found that even Raspberry makes the same claim...

"runs directly on embedded hardware"

https://www.raspberrypi.com/documentation/microcontrollers/m...

I don't understand why they have the need to do this...

dividuum · 4 months ago

Huh? MicroPython literally does exactly that: You copy over Python source(!) code and it runs on the Pico.

Always go for GmbH. UG will make you account for everything with your private money. If something goes wrong in your business you'll be dirt poor.

dividuum · 5 months ago

That doesn't sound correct. UG is identical to the GmbH in that regard. Do you mean a GbR?

In addition to growing pages using VirtualAlloc, it's also possible to have the same memory pages mapped at different locations by using memory mapped 'files' (even when the backing file is just the paging file). This means that if your new block isn't contiguous, you can remap the existing memory without a copy.

However, system calls also have overhead (thanks Meltdown/Spectre mitigations), and you might not come ahead by avoiding memory copies.

dividuum · 5 months ago

Is there another option besides memfd_create? I'm currently using those to implement a circular buffer that avoids having to reconstruct objects if they happen to cross the size boundary by mapping the same memory twice consecutively into the process space.

> They’re not saints, especially with the games distribution platform monopoly they’re sitting on top of

They got and have maintained that monopoly (I'll let others debate the merits of that wording) by being very very good to their users, which doesn't make the existence of the monopoly evidence that they aren't saints. If they were maintaining it through anticompetitive means, sure, but I've never seen anyone claim that they are, even Epic (who would definitely be making noise if they thought they could get anyone to listen).

The desktop video gaming ecosystem is in perhaps the best shape possible: there's one clear winner at the moment who makes all customers very happy, with a few runners up hedging against that winner becoming abusive after all. If Steam became worse than Epic it wouldn't take long for Epic to overtake them, but as long as it's not worse it's nice that everyone has agreed on a standard platform.

Helps that they don't have to be very very good to shareholders that don't give a fuck about games and just want money. I'm not really looking forward to find out what happens once Gabe passes on control of the company.

Absolutely agree. Real recipes, tested by actual cooks (home or professional) with genuine photos, matter far more to me than avoiding messy screens. Does anyone know trustworthy sites that consistently offer recipes meeting these standards?
