Being so absolutist is silly but their counter argument is very weak. Can I invalidate any memory safe language by dredging up old bug reports? Java had a bug once I guess it's over, everyone back to C. The argument is so thin it'

fwiw, the M139 engine they're putting on those AMGs is completely insane. It's a production 2.0L 4-cylinder engine making (in the most powerful config) 350kw. From the factory. Insane.

Toyota with the G family and JZ family + Nissan with the RB family too. They were prolific in RWD cars. Daewoo put one in a FWD car in the mid 2000s for some reason too.

Yes? That's called a bug? The standard library incorrectly labelled something as safe, and then changed it. The root was an unsafe FFI call which was incorrectly marked as safe. It's no different than a bug in an unsafe pure Rust

What is a safe ABI? An ABI can't control whether one or both parties either end of the interface are honest. You can't have safe dynamic linking, dynamic linking requires you to trust the library you load with no ability to veri

You're both wrong, the Mirai uses a fuel cell as the voltage source for an otherwise EV drive train. The Mirai is an EV with a fuel cell instead of a battery. There is no ICE in a Mirai.

I remember Star Wars Jedi Survivor had a 5-6 minute shader pre-compile on my 5950X. I heard of people well into the 30 minute mark on lower core count machines. Battlefield 6 was a few minutes on my 9950X, higher again on lower core count C

Yes, many games do that too. Depending on how many shaders the game uses and how fast the user's CPU is an exhaustive pre-compile could take half an hour or more. But in reality the exhaustive pre-compile will compile way more than wil

by MindSpunk 8mo ago
Depends what you're precompiling. For Vulkan you already ship "pre-compiled" shaders in SPIR-V form. The SPIR-V needs to be compiled to GPU ISA before it can run. You can't, in general, pre-compile the SPIR-V to GPU ISA

The CPUs in their SOCs were not up to snuff for a non-portable game console until very recently. They used (and largely still do I believe) off the shelf ARM Cortex designs. The SOC fabric is their own, but the cores are standard. In perfor

It pains me how important TKO is for Ivanova's character because it's otherwise got to be one of, if not the worst episodes in the whole show's run.

It's probably worth watching TNG before DS9. The contrast between TNG and DS9 with DS9's darker tone is an important part of the show. Probably the best episode in the whole series, "In The Pale Moonlight", is made all t

The first season is definitely the most conventional (for the time) and I think that reflects in some of JMS's statements saying the show was still getting onto its feet through the first season. Having the serialized story was very un

WGPU is just a layer over the top of the native APIs on any given platform so unless Zed's DirectX/Metal renderers were particularly bad it's unlikely WGPU will be better here.

The McMurtry is a race car so it's not surprising it's that light. However it still pays a price compared to its contemporaries (go look at the weights of various LMP1 or LMP2 cars, even old cars like the Mazda 787B was ~850kg iir

Acceleration is about the only selling point of a sports EV. They're so ungodly heavy because of the batteries that they handle like barges. They need giant tyres and so much ESC and software control because these things weigh almost 2

Do we really need to jump onto a tangent about evil cars and evil car infrastructure on a post about b-splines and curve sections? Everything in the article applies equally to trains and rails. We get enough complaining about evil car-centr

Drawing lots of single pixels with alpha blending is probably one of the least efficient ways to use the rasterizer though. A good compute shader implementation would be substantially faster.

M-series have a substantially wider memory bus allowing much higher throughput. It's not really an x86/M-series thing, rather it's a packaging limitation. Apple integrates the memory into the same package as the CPU, the vast

Been having a nice break over the new year, thank you :) I can't argue with sticking on IPv4 when you have no need for IPv6. However, people saying no NAT means no firewall really bothers me because it's just wrong and usually get

If I'm interpreting that correctly they're using an IL2CPP compilation system that hooks into Roslyn and not using .NET Core's AOT technology. It's possible to ship C# on consoles, obviously, because Unity already does i

by MindSpunk 9mo ago
Do you have examples? As far as I'm aware based on current info there's at least one current console vendor that requires all native code to be generated by their SDK.

CoreCLR doesn't help on console platforms because you can't ship the JIT runtime. To my knowledge CoreCLR's AOT solution won't work because of SDK and build requirements for shipping builds on consoles. I believe some co

WebGPU is far from cheap and has to do a substantial amount of extra work to translate to the underlying API in a safe manner. It's not 1:1 with Vulkan and diverges in a few places. WebGPU uses automatic synchronization and must spend

While this is 100% true for the system allocator, hitting OOM there you're likely hosed, it isn't true if you're using arenas. I work on games and being able to respond to OOM is important as in many places I'm allocatin

Nvidia had a driver for Vulkan for Kepler which launched in 2012, AMD had support all the way back to GCN 1.0 (also 2012). Intel did have issues supporting it, I can't recall if it was for hardware reasons or just lack of desire for a
