Yes, linked lists have terrible cache behavior and usually the performance of any packed structure with less pointer chasing should beat it. ArrayList, Vector, whatever you call it usually is faster. But computers aren't fast in alloca

Having a background in Haskell (and C) made me able to jump in and be productive in Rust within hours. And that's a language that is considered to have a steep learning curve. Never used it in production either but I did use Haskell to

Well it seems that the developer wanted to support embedded platforms too. printf isn't a part of the freestanding C standard, and neither is snprintf. That said, there are portable freestanding snprintf implementations out there with

I have used Nuklear in a medium sized hobby project, and it's kinda cool but I will be migrating away from it. I am not aware of it being used in shipped products, unlike Dear Imgui which is a more popular alternative. The first reason

Graphics was somewhat more complicated back in the day. In the days before we had enough memory to hold a full screen framebuffer, there was a lot of magic going on with cathode ray tubes, video signals, dedicated hardware sprite engines, m

The lunar orbit is inclined so that the moon moves between about +/- 28 degrees north/south latitude with reference to the Earth equatorial plane. That's Earth's axial tilt of ~23 deg + the inclination of the lunar orbit

The moon moves slowly but the Earth rotates quickly. Most of the earth surface can be seen during one day. The earth is not illuminated by sunlight all the time, about half of the lunar month would be completely dark. Moon is in an inclined

> Doesn’t the LLVM API go through breaking changes fairly often? How do you track all that and keep your sanity? No, not very big ones. But they give no stability promises. If you're using a language other than C++ via API bindings,

No, sorry, I don't know anything about the M1. If you want to achieve something similar to _mm_stream_xxx, ie. bypassing the caches and causing bursts of DRAM traffic, try making some uncached/write combined memory mappings and wr

by exDM69 6y ago
If you compile it to x86_64, that _mm intrinsic will turn into a single instruction. No need to show the disassembly. Thanks for the info.

Your result is hardly surprising as Apple M1 is a different CPU architecture using the ARM instruction set. It is unlikely that the CPU circuitry related to this particular function would be similar to Intel x86. This might not even work wi

iRacing doesn't have rallying, only rally cross, which despite the similar name is not the same category of motorsport. RX is multi-car circuit racing, no pace notes, etc. That said, how is the dirt racing in iRacing? I haven't ha

Yes, well, sort-of. Colin McRae was a pretty cool game in its day but didn't really have the great physics that RBR did. But it was an earlier game so it was the best that there was available.

I don't think that's going to happen, they will just quietly kill Dirt Rally. That game is just way too difficult for a mainstream audience so it makes a poor platform to milk microtransactions. The rest of the Dirt series (same n

Oof. I was just getting used to the idea that we have a decent rally sim/game (Dirt Rally) again. It's a niche genre that requires a specialized physics engine, and there hasn't been decent entrant after Richard Burns Rally (

It means that if your contract is for 37.5 hours per week, you don't need to do email and be available on im outside of your daily 7.5 work hours. Being on call needs to be negotiated separately.

Yes. This seems to be a very divisive issue, others prefer working from home, others prefer the office. Some are downright miserable in their home offices. I'm guessing some were also miserable at their work offices but didn't hav

I wouldn't call it difficulty, or even complexity. Verbose is more apt. It's daunting for a beginner but for a seasoned graphics programmer it is fairly straightforward. But still really verbose.

Best explanation of the two APIs I've ever heard. OpenGL "hello triangle" is short only if you cut corners. If you do it the way you'd do in a production app, you're not that far off from the lines of code it takes

Exactly. I like to say that git is a "white box". You need to understand the internals to be able to use it. Contrast this with "black boxes" where you don't have to or even can't understand what's going o

Sure, but then you can't use your existing ssh credentials. And need to have a custom server and protocol. And being able to use pijul (or git) over plain old ssh is a pretty nice feature.

Authentication. Ssh deals with keys and accounts and all that which SSL/TLS don't do.
