> Git and P4 are not meant to be directly competitive here. True, but for the problems that Git LFS solves P4 is usually the other option. P4 handles large binaries very well, caveat being the rest of P4. In some projects the caveats are

From my experience Git LFS is extremely brittle and will break your local check out if you so much as breath on it wrong. Perforce is an expensive solution to the problems of LFS, and I've yet to find a workflow as powerful as my git w

Absolutely, I agree. I suspect that explicit branch for the hot path is doing a lot too. Separating the hot path into a prefix before calling into a separate cold function should still generate better code. Your prefix only needs to allocat

I'm not convinced the performance benefits are entirely the result of the more compact object representation. It definitely would help, but looking at the code snippets the author provides for the add instruction there's an import

Since when do Samsung ship driver updates? I'm being a bit hyperbolic but from my experience Samsung don't ship them very often either. To Google's credit, the Pixels get them quite frequently. Samsung is still better than mo

The Pixel 10 and 11 GPUs are offensively bad. Not only are the Power VR GPUs slow, and less capable feature wise than Mali and Adreno (Xclipse is still around too!), but the tile Google put in the Pixel 11 is actually an _older_ design than

A VGPR is not the same thing as a vector register like in SSE4 or AVX. Each addressed register contains a single 32-bit value. A VGPR differs from an SGPR in that each thread in a thread group can have a different value in that register. An

Yes, of course writing naive code assuming each lane in a thread group is a real thread is going to cause problems, but I didn't feel like I needed to go into that level of detail replying to someone just learning about GPU internals.

It's not really obvious unless you go in depth of the details on modern GPU architecture. GPUs aren't really SIMD, they're SIMT (single instruction multiple thread). The silicon looks a lot like SIMD, but the programming mode

Most games haven't rendered directly into the "screen buffer" for 15-20 years. Vast majority of titles use deferred rendering, and lighting is done off screen too. Usually the only thing done to the "screen buffer"

You can't actually ship a game on the porting toolkit without breaching the license. It's intended by Apple to aid porting to use Mac's native APIs one component at a time, but the license forbids redistribution or commercial

That's largely what matchmaking aims to solve, assuming you have enough players you can get a reasonably balanced match to drop people into. Bots can teach basics, but many of these games rely on abusing game mechanics in ways the deve

If you want to get pedantic the hardware rasterizer in your GPU doesn't rasterize "3D triangles" either. Any notion of '3D' comes from how you project your vertices when transforming them through your coordinate spa

You could try and do this today, to an extent. You could skip Vulkan and talk to the kernel driver in your app directly. vulkan-1.dll is regular user-mode code, there's nothing special about it. Nobody does this because it's a col

The Apple developer terms of service require all app submissions to come from a Mac. Apple could've chosen to offer no tools and leave it to the community to build their own. I think that's reasonable. I don't expect Microsof

I'm not really sure how any machine is more affordable than the $0 it should cost because you shouldn't need a Mac. It's absolutely true that you can get by with a base spec Mac Mini, but often you can't with bigger proj

Why should you need a Mac to build for iOS at all? What makes Apple so special here? Cross-compilation toolchains aren't forbidden alien technology. Forcing people onto Macs is such a pathetic way of extracting rent from developers and

Curious why you'd move from C# to Rust. C# has you covered mostly for memory safety so I would guess performance or lots of shared memory across threads?
20.
by MindSpunk 2mo ago
This is the answer I think. The correctness of your safe code is dependent on the diligence of the unsafe code except for the most simple cases. A kernel is going to have a pretty high unsafe to safe ratio compared to most usermode apps.

Valve is just hedging against Microsoft having a big red button to kill Steam. They've built their kingdom on top of Microsoft, and Microsoft would love to have it for themselves I'm sure. It's in Valve's best interest t

Not recommending the Steins;Gate anime adaption is pretty wild, it's an incredibly highly rated Anime series. The story telling language of a VN and an Anime are very different so it's no surprise they don't perfectly capture

The hard part of Linux ports isn't the first 90% (Using the Linux APIs). It's the second 90%. Platform bugs, build issues, distro differences, implicitly relying on behavior of Windows. It's not just "use Linux API"
