I've been hearing a lot of "Amdahl's law" regarding AI - the rule that says the slowest part of a system sets the speed of what you can accomplish. On one hand, this means that AI has sped up software (so there is more s

One problem is that the core-years for RSA-250 were in 2017 Skylake Xeon single core terms. If you can rent a dedicated 96-core Epyc for $1/hour (cheap dedicated host), the combination of IPC improvements (>2x) and core count make 7

I remember thinking the Matrox cards in the 90s (Millennium, G400) had super-solid drivers, and their 2-D image quality was amazing. Interestingly, at the time, we were doing software 3-D rendering and NVIDIA RIVA TNT was much slower for

This is both interesting and weird! We know the typical LMS responses for human cones (e.g., Stockman-Sharpe) that could easily be plotted instead of the bell-curve-like things they use here - why? Is it good enough for illustration? You co

No - there is a huge difference between "this AI created this image" and "this user did it" - the first we need more of, and the second is a big privacy concern. The article does not say anything about identifying a user

Not telling someone you used AI is a perversion of writing. Also agree that an AI proofreader should not claim authorship, but in most other cases, the AI is not reading your mind, it's only watermarking its own usage, and we kind of n

It's fine for installing, but uninstalling is madness: Windows uninstallers try to clean up all the registry and user profile stuff they install. Mac apps seem to just leave stuff behind in Local Settings or Caches forever? Container

This seems to do XYZ->RGB without any gamma correction. XYZ is linear, as is the transform to RGB, so we usually convert linear RGB to (gamma-encoded) sRGB at the end. The JS code seems to output linear RGB directly to the webpage (missi

So if this Mac uses 30-50W, that's 40-60 tok/Wh...vs maybe 80k for a modern GPU cluster? So that's about 1000-2000x more power for the SSD streaming, unfortunately.

Nicely illustrated, and only one criticism: our preference for luminance (using more bits for "Y" vs "Cr/Cb") isn't due to the number of rods in the eye - there are so many rods so that we can capture more phot

I think portability is very confusing: they rolled out passkeys with no device portability (device-bound) and only recently added it (CXP). So for anyone with multiple devices it was a relative disaster - why should my Windows PC hold a dev

HEVC used to be a capped license per organization, so not providing it in the OS seems really harmful and expensive. Has the cap changed recently?

Yes, I think part of it was the "dark fiber" at the time, made bandwidth relatively cheap. But most personal photos don't use that much bandwidth - being able to use them anywhere online (which iCloud and Instagram don't

AIs and podcasts (which also grew a lot recently) are free alternatives, and pricing matters as much as attention.

This is gross, it could be a onetime fee. It's hard to remember with all the ownership changes, but the Photobucket era was really a different time, of "it's your data, you're in charge, and we give you maximal control o

I'll argue for the +0.5 solution. First, I don't like half-sized intervals at the edges, and second, a 255-based representation is typically a SDR (not HDR) image. RGB values represent luminances against some adapted state, and a

Except this math is 10x too high (unless accelerated depreciation is all of it) - a million tokens at 28 tokens/sec and 75W and 20c/kwh should cost $0.15 not $1.50. (And less with MTP.)

Two questions: 1. What is the search index? 2. The "description.md" example has things like "faces -> cluster_id". Is this from Davinci Resolve's face index? Things like faces+names and locations are really impor

The aspect ratios were much "taller" back then, which was kind of better for editing code. All these late 90s designs were near NTSC at the time - aspect ratios like 1.25:1 (1280x1024) or 1024x768 (1.33:1). Monitors have always fo

If you back up to "intention" it's fully insane to make a GDPR argument against on-device AI. Yes it downloads bits, but those bits are not there to identify you - they are basically a local copy of the internet. This enab

Chrome seems to use a custom inference runtime also (in addition to Gemini Nano). It would be better if this were all interoperable. The WebGPU alternatives like WebLLM do not have the same access. I've been trying these models out for

Any benchmarks? Scrolling is using 16% of my GPU (vs 5% in Sublime). Also things like mouse-down to activate a tab (vs mouse-up in Zed) make Sublime feel faster.

Doing this without the parents on board does not work. Kids can lie about their birthdate by a few years. Facial age estimation has error bars of like 5 years and many teens don't have any ID. Younger kids use a parent's phone. Ma
