Really? Why? I'd bet the opposite: the worst of the things happening with OpenClaw aren't being revealed.

Not a shareholder, but on first try, it won't do it because it recognizes Iger's name. And clearly the deal is fresh because it balked at Mickey Mouse too. But it has no trouble with just, "mouse": https://sora.chatgpt.com/p/s_693ae0d25bbc819188f6758fce3f90c...

It's likely that I'm seeing this from my deep into ComfyUI bubble. My impression was that AUTOMATIC1111 and Forge and the like, were fading as ComfyUI was the "what people ended up on" no matter which AI generation framework they started with. But I don't know that there are any real stats on usage of these programs, so it's entirely possible that AUTOMATIC1111/Forge/InvokeAI are being used by more people than ComfyUI.

Did you test some local image gen software in that you installed the Python code on the github page for a local model, which is clearly a LOT for a normal user... or did you look at ComfyUI, which is how most people are running local video and image models? There are "just install this" versions, which eases the path for users (but it's still, admittedly, chaos beneath the surface).

Mass shootings in the US, are a little over 1 a day. School shootings are a subset, and as cudgy says, so far 13 this year.

"NTSTC content at 23.976 I'd hope the player would just speed up at that point, but even if not... judder at 120 Hz is better than at 60 Hz."

I'd bet money when TVs are advertised at 120 FPS, they're really 119.88 FPS, so no judder showing 23.976 FPS and the other NTSC-off display rates.

It's a regular expression, and OS/2 was referred to in many ways, so try something like: "os-2|os\/2|os2" (without the quotes)

I get 136 results, from that query.

Well, they sort of do: they keep referring to the 4090, on their Github and primary promotional pages (https://wan.video/).

But really all the various video models really want an 80+ gig vram card, to run comfortably. The contortions the ComfyUI community goes through to get things running at a reasonable speed on the current, dinky-sized vram consumer cards, are impressive.

As jasonjmcghee says, they're available... but if you go to ollama.com and set models to "newest" you'll see Mistral (specifically mistral-small3.2 at this writing) because they seem to not sort the models based on newest update: only newest "group" or however you'd phrase it. So you need to scroll down to "qwen3" to see it's been updated.

Slightly frustrating. But good to know.

I use Markdown Viewer, in Chrome: I'd bet there are multiple equivalents in Firefox and Safari. Well. I don't know what Safari's extension universe is like but it seems likely.

You're not the only one thinking that: https://www.nvidia.com/en-us/project-digits/

128G of unified memory. $3K. Throw ollama and ComfyUI on that sucker and things could get interesting. The question is how much slower than a 5090, is this gonna be? The memory bandwidth isn't going to match a 512 bit bus.

pkroll — Wed, 11 Dec 2024 20:02:43 +0000

That's too simple a comparison, against something that's a little more complicated. A 720p stream without adequate bandwidth can have terrible artifacts, mostly showing up during fast motion/panning/action. They can look objectively worse than DVDs.

I don't get it: the new models still need to be used somewhere, unless you're coding everything yourself, and that means they'll mostly get used in the updated ComfyUI nodes that work with the new checkpoints and LoRAs (and are available today).

pkroll — Tue, 29 Oct 2024 22:31:06 +0000

Well, MS isn't fatal, but it certainly doesn't HELP... people with it have a generally shorter life expectancy (by like 7 years) from complications with something else, like heart disease or cancer.

None of which takes away from it being terrible that we've lost Terri Garr.

Worked with a lot of directors on their first or nearly first movies, like James Cameron, Martin Scorsese, Francis Ford Coppola, Peter Bogdonovich, Ron Howard. Even the Fantastic Four movie he produced had some pluses (the Red Letter Media review is worth watching).

For anyone who hasn't gotten into the coffee insanity yet, he doesn't mean his friend literally gives the coffee acupuncture... but a cork with some acupuncture needles (or a device that looks like such) is commonly (!) used to stir/even out/redistribute/break up clumps of coffee in the portafilter before tamping. And reading that I now need to go get some coffee.

pkroll — Wed, 01 May 2024 18:47:07 +0000

Not just dropout: the disc stacker will set each pixel to the median (if there are enough copies) or an average (if there are just two) so even slightly off pixels on one disc of three, will be caught/fixed. (You can do the same thing with VHS, but not with their stacker software. You'll need to resort to VapourSynth or Avisynth/Avisynth+.)
