In theory the parsing could run at a low privilege level subprocess. Root/admin is only needed to get the bytes.

The other interesting trick is you need a separate RNG for visual only affects such as particles than the one you use for the physics simulation. Depending on the game during replays, you could position the camera differently and then parti

One of the hardest determinism bugs I had to solve on the PlayStation three was that the PPU and the SPU actually used a different instruction set and had a different internal floating point register size. We had a multi threaded physics si

Instant replays that require long-term deterministic behavior have to be bit perfect in a way that is dramatically hard harder to implement if trying to also do network synchronization. The hard parts of each of those is fundamentally diffe

E13 was a great, simple, good looking WM I used for years. Eventually moved to Fluxbox then back to macOS when it went Unixy.

You are comparing orbiting earth in a shuttle to a lunar flyby in a pod. Very different risk profiles.

Messaging platforms where people receive and promptly respond to messages are more successful in the long run. That's why SMS overtook email. If you own a messaging platform there isn't anything inherently nefarious about pushing

I was down there recently on a helicopter-based expedition and they set up a forward base of operations with a few days of emergency rations in case of unexpected weather that prevents you from returning to ship. I asked them what happens i

As best I can tell we've never sold the same product twice. Product roadmap is "whatever the last person I spoke to asked for." And tech debt maintaining a grab bag of 5,000 almost-but-not-quite-entirely-production-grade &quo

Is this just a case of waiting to stay private while still giving current employees some liquidity?

Yeah I thought LIDAR was used for actual focus and depth map was then computed from the multi-camera parallax.

CORE only works on kernels that support BTF. This post introduces one workaround which is to generate BTF data for kernels without it. That's still only half the problem though. You also need to write your eBPF program so every kernel

As someone who studied physics and electronics for many years, I still appreciate an article like this for reminding me how profoundly weird science is. Working day to day with the equations and practical applications of electricity gives y

GitHub pissed me off recently by giving us a one month reminder of our renewal, but having required two months notice to reduce our number of seats. As a result, we are ending up paying for twice as many seats as we currently need.

If you exceed the inheritance tax exemption then you are taxed on the $10k so LTCG would be double taxing. You could argue that the inheritance tax should have a much lower exemption but double taxation is harder to justify.

Listen. If it’s never supposed to happen then you definitely want a customer to tell you if it happens. Best way to make sure that happens is to insult their mum. It’s just good engineering discipline.

The physics game sim step had to be hardcoded but you could vary the graphics rendering independently. That did mean you needed to use a different RNG for sim objects and graphics-only particle effects. I worked on the deterministic instant

Yep, all valid. When I started on it we had to do everything ourselves. But by the time I did serious dev on it our engine team had already build vector/matrix libraries that worked on both ppu and spu and had a dispatcher that took ca

In general images are often limited by depth of field, camera movement, subject movement or lens resolving power. Some of these can be improved upon with better software. I have been working on software to do this myself as for fun. For the
