dagmx··on MongoDB CEO resigns to join Meta
Meta’s chief AI officer is a 29-30 year old who was acquihired as part of his data labelling company. He’s not a model developer.

Meta hires in strange ways. I’m convinced it’s more about your sales pitch going in.

dagmx··on AI coding has made CI a bottleneck, so we reworked ours to keep up
In my experience everyone is just rebuilding the same wheel over and over.

A lot of people may be more empowered to create things now with less up front effort but it doesn’t lead to having better ideas or more actual system architects.

dagmx··on M5 Ultra Mac Studio Review
That sounds a lot like AI fantasy slop.

Apple just shifted to N2. They’re not going to be doing another major shift right away.

And TSMCs own roadmap would put your hallucination years away at best for a a product that follows a roughly annual cadence https://www.tomshardware.com/tech-industry/semiconductors/ts...

dagmx··on The scourge of x86 emulation
For reference , Fex is a translation framework for x86 to ARM much like Apple’s Rosetta2 and Microsoft’s Prism.

Valve sponsor development as it’s also the way the new Steam Frame supports x86 games. It’s also being used (as a fork) in Crossover Beta to replace the use of Rosetta2.

dagmx··on Canada welcomes EU proposal to become 'associate member'
Tech communities like this skew more libertarian I find, which tends to be anti everything that isn’t immediately self serving.
dagmx··on Apple A20 Pro Geekbench Result
Geekbench when run on Asahi Linux is practically the same as when run on macOS, just like Linux and Windows in the same x86 chip don’t give significant differences.
dagmx··on Apple A20 Pro Geekbench Result
Because it ruffles x86 feathers, despite geekbench corresponding very closely to SPEC as well and there being no indication that the results aren’t comparable.

What people willfully conflate this with often is that you shouldn’t compare FLOP numbers between GPU arches and instead rely on benchmarks.

dagmx··on Apple A20 Pro Geekbench Result
You have that exactly backwards. The MacBook Neo released with the previous years A series Pro chip.

It’s currently got an A18 Pro.

dagmx··on Asahi Linux on M3
Your intuition here is wrong.

Processors, not just Apple’s, change constantly between generations. The core instruction set doesn’t change, but they get new capabilities, not just with new instruction sets.

Remember the SoC isn’t just the CPU. It’s display engines, GPUs, storage controllers, video decoders and more.

Even outside of Apple, you’ll see hardware vendors provide Linux patches for their latest CPUs to keep working well. There’s some baseline functionality that works out of the box but it’s never a free ride.

dagmx··on Boot a Virtual iPhone via Apple's Virtualization.framework
Sure, you can also have iOS binaries forward relevant iOS SDK symbols to macOS. That doesn’t mean they’re not different SDKs with different limitations, and not everything that is on the store can be patched to run in the simulator because there are legitimately symbols missing or with stubbed functionality.

It’s literally a different toolchain and SDK.

dagmx··on Boot a Virtual iPhone via Apple's Virtualization.framework
The simulator is a different SDK target than iOS itself.

You have to compile completely independently for it, and depending on your dependencies they may not compile for the simulator.

Additionally the simulator runs a really ancient and feature restricted version of Metal. That means you can’t test a lot of graphical things that the hardware actually supports. I’m not sure if this supports GPU passthrough but the macOS VMs do, so that alone would be a huge improvement if possible.

dagmx··on Apple introduces M6 and M5 Ultra
HBM itself is very expensive but it’s not really fair to compare to LPDDR or GDDR

They’re very different things.

The more logical argument to me is that Apple uses its upgrade price points as more than just direct BOM and rather as a proxy for things that are amortized across all their sales like support/warranty/etc so higher SKUs subsidize the costs of the lower ones.

dagmx··on Xiaomi: New CPU matches Apple cores single threaded, much faster multithreaded
I’m not trying to say you shouldn’t be excited by it. But there’s a significant number of caveats to every single number you posted but you glossed over the points I made.

And in being defensive, you jumped straight from the topic you were discussing (GPU perf) to CPU perf numbers to try and make a point.

There’s a difference between being cynical and pragmatic, just as there’s a difference between being hyped and realistic.

You haven’t seen this in a product. You’re seeing development board numbers. Be excited all you want but it’s a public forum, if you want to just post without any responses make a blog.

dagmx··on Xiaomi: New CPU matches Apple cores single threaded, much faster multithreaded
I’m not sure I follow why the performance is “Insane”

This is a M5 level chip that runs slightly within a ballpark of M5 wattage (afaik M5 is between 15W max on an iPad and 30W max CPU+GPU on a cooled Mac)

This is running in a thermally unconstrained bench setup and has potentially worse power consumption with what will be lower than previous gen performance when this and the alleged M6 are truly out.

dagmx··on Why does Opus 5 feel worse to work with?
Oh yes, Claude seems to be loving the word vacuous recently. My test bed side project is full of vacuous this and that now.

I even try and get it to define what it classifies as vacuous and it can’t do so without getting stuck in some kind of trap. It’s like a word with some kind of huge gravity for it.

dagmx··on Japanese court overturns Red RAW video patent
Ah fair, I forgot Panasonic owned Lumix.

Though the lawsuits are more complex with multiple parties suing RED, of which Nikon also fought RED and ended up buying them out to win that side of the battle. On the panasonic side it was more of their cinema line of cameras rather than Lumix that was the driver (though they have trickle down)

And prores isn’t necessarily RAW, it’s just one of the variants.

dagmx··on Japanese court overturns Red RAW video patent
Unless I’ve missed it; Lumix has nothing to do with this long standing patent battle. Could you elaborate on the supposed relationship?
dagmx··on I'll be stepping back from leading product for X
I disagree with your assessment. My twitter feed pre and post Elon’s takeover changes dramatically.

Pre his takeover , it would more reliably show me my niches of design, technology, gamedev etc

After his take over I’d start seeing more and more boosted content from frankly abhorrent individuals. The whole blue check mark thing being paid instead of truly verified also messed with the algorithm.

I’m sure it’s doable to curate it into what you want again, but it was a night and day shift for me and why I eventually left.

Even filtering out content wasn’t enough because it would get boosted through other means.

dagmx··on SwiftUI After 7 Years
Yes because SwiftUI is way more self contained and minimally verbose, it’s a better fit for LLM use than AppKit/UIKit
dagmx··on IMAX vs. IMAX 70mm: The difference between these two cinema formats
Thank you very much for the corrections here. As someone else who has professionally worked in the film space, it always irks me when people talk about film in digital resolutions for the reason you mention.

I also agree with many of your other corrections but that is the one I wanted to ageee with the most as it’s my biggest pet peeve when I see people claim “film” is equivalent to a given resolution.

Anything analogue can be (almost) infinitely resolved but that doesn’t mean it’s going to be effectively good at all those resolutions. Almost nobody thinks of the quality of medium and lenses when making those claims.

dagmx··on How is the Bun rewrite in Rust going?
A post mortem is a very common term in many industries on how something went after you shipped it.

You’re taking it very literally here, it does not involve anything being dead or killed.

We’ve used this in the software, games, film and construction industries for decades at this point.

Substitute Mortem for Ship and that’s how people use it.

dagmx··on Ford Will Use Apple Software in New Self-Driving System

dagmx··on Blender 5.2 LTS
The commercial Autodesk apps still dominate, as do Maxon apps like C4D for motion graphics and zbrush for sculpting.

The big problems are that license cost doesn’t outweigh the pain points. In production I can get support from Autodesk for specific bugs without rediverting my production resources to fixing it.

Blender has no C++ API and even the Python api is not stable version to version. Studios live by maximizing their competitive advantage and that takes the form of extending the DCCs with custom pipelines and high performance plugins. With blender I’d have to maintain a full fork.

Also blender’s ghost UI system is significantly worse than Qt. It also means I can’t share the Qt tools I built for the rest of the apps with blender.

And while Ton was still CEO he heavily told studios he didn’t want their business. He believed blender shouldn’t be part of a pipeline but be the whole pipeline. These were his explicit words in a presentation blender gave at SIGGRAPH.

For background, I was a lead engineer in the film industry and still am quite involved with industry development while also contributing to blenders code base. My partner also works for one of the big animation studios.

I think blender is great and it’s seeing adoption professionally but there’s a lot of fundamental things that need solving before it displaces the current status quo DCCs.

dagmx··on Apple's rumored M7 Ultra targets 1.5TB and Blackwell-class AI performance
Do you have comparisons for Apple’s GPU to NVIDIA’s at the same power and thermals?

Right now the M5 Max is one of the best laptop compute GPUs for blender rendering and doesn’t do too badly on raster tests either. But it operates at a fraction of the equivalent NVIDIA parts.

It’s more that Apple doesn’t provide a competing tier of device as the high end NVIDIA GPUs. But within the tiers they do provide they’re fairly competitive.

dagmx··on Microsoft fire idTech team at Id software
A lot of unreal engine games also fork the engine. If your bar is being forked then unreal doesn’t meet the bar for a lot of people either.

3D Engines of that fidelity are rarely genre specific. Editors might be but the engines are often fairly flexible because most genres share a lot in 3D space.

dagmx··on Microsoft fire idTech team at Id software
Your first statement is wrong. The new Indiana jones game is not an FPS and it uses the same engine
dagmx··on Resetting Xbox
Oh I definitely agree the C-suite at Microsoft needs blame. Microsoft need everything to be framed as avenue into services.

But Phil was the one who dug two incompatible holes and kept digging hoping they’d meet in the middle with buried treasure.

dagmx··on Resetting Xbox
Okay so your entire argument hinges on her having the ear of Satya , and out arguing Phil?

But even then you wouldn’t be able to deny that Xbox was floundering under Phil.

And for all of this you’d still be left with conjecture?

dagmx··on Resetting Xbox
How would Asha pull him out? How do you think she even had that kind of authority or seniority?
dagmx··on Resetting Xbox
Based on what? This just feels like baseless conjecture given she hasn’t been at Microsoft for that long.
