A slight re-organization of Priest's "Efficient Scaling for Complex Division" to make it compatible with "try to divide the dumb fast way inline, then branch to rescale only if necessary" while preserving scale invariance of rounding.

Also fixes it up to work for Float16, which the original approach does not.

Further optimization possible and pretty straightforward.

What #mastodon client do you use for iOS. The official one is has lots of issues (hangs, unable to post images, etc)

There's a retired couple living in my mom's apartment complex who seems to spend 12 hours every day sunbathing outside during the summer months. They did this when we were visiting last year and they're continuing the streak apparently. After you've lived in a warm climate for a while, the whole idea of sunbathing starts to seem obscene, but this is something else.

Benji being unable to do big runs with me anymore due to age / epilepsy / heart murmur is the biggest sign of mortality I’ve had in my life thus far.

And he doesn’t understand as I run off that he’s not fit for it anymore and gets so upset that I’m leaving him behind. Heartbreaking!

At least he forgives me once I am home.

If you enjoyed the visuals in the Dune 2 movie and want to try it out at a grand scale, at 230m tall, the Great Sand Dunes (CO) is a worthy stop. Just be careful, the nearby towns entire GDP comes from speeding tickets, and they will go as low as to ticket you for speeding during a lane crossing pass.

F**ks sake they changed something pretty fundamental between UE 5.4 Preview and UE 5.4 Final - the ability to have multiple objects in an asset file, which SUDS relies on - the dialogue and string table are in the same asset; now the string table is gone.

I was worried they might do this because they started hiding them in 5.3 (not a problem) so I tested 5.4 Preview but everything was fine. Now it's completely broken in 5.4 Final, every single dialogue line is <MISSING STRING TABLE ENTRY> 😠

Annoying that in Vulkan compute I can't easily get hold of the optimal minimum number of invocations
of a shader to run.

Subgroup functionality gives us the SIMD lane width with subgroupSize (see https://www.khronos.org/blog/vulkan-subgroup-tutorial by @neilhenning ), but as far as I am aware there's no easy way to get the number of subgroups which can run simultaneously.

For many applications this doesn't mater, but in some cases it's really useful to know.

Does anyone know why Creative Commons recommends not to use their licenses for Software (beyond the carveout for CC0)? Curious why their attribution licenses couldn't apply to software!

The day I retire and work on my own programming language for the fun of it I'm gonna ban the word ‘error' appearing in any filename. Having a multi-million line build log and searching for the actual fail does my head in!

I wrote up a little thing about how you can write your own constant folders with Clang using GCC's __builtin_constant_p https://www.neilhenning.dev/posts/yourownconstantfolder/

We're making progress with the GPU path tracer in our Avoyd Voxel Editor, now with decent performance on both AMD and NVIDIA discrete GPUs (I've not yet been able to test Intel).

For now we're disabling spirv-opt in our shader build pipeline due to it causing a >4x hit to performance on older AMD GPUs.

If you own Avoyd then do try out the latest Beta.

Oh cool - we've announced the stuff I've been working on for the last 18 months! Transactional memory in C++, to bring Verse semantics to our existing Fortnite and Unreal Engine C++ codebase. https://www.unrealengine.com/en-US/tech-blog/bringing-verse-transactional-memory-semantics-to-c
