Well, the problem is that the encoding process in AV1 does remove grain, only to add fake synthetic grain back in. My objection is not to the idea of encoding grain, it's with replacing it with fake synthetic grain. It's kitschy,

I don't think it really counts as compression. It's like taking the statistics of a text and generating a new one with a Markov chain. In other words, it is complete nonsense, texture synthesis, like the way some people go for pri

Writing to a (non memory-mapped) file takes a call to write(), whereas setting pixels in a framebuffer might just be a memcpy(). I think, given the post we are commenting on, it is OK to distinguish these things. Historically, framebuffers

See my other comment about Plan 9. You can certainly organize to be able to mmap a file that represents a framebuffer, but that has nothing to do with the comment I was replying to. And it is exactly the kind of thing Torvalds is objecting

The point is that writing to a file is basically passing a message to the kernel. Writing to a framebuffer is writing straight into memory.

Plan 9's rio window system expected most graphical clients to use the draw functions, which operate by writing to /dev/draw. /dev/draw wasn't even a framebuffer—it was a control file that you wrote messages int

Add to that the fact that this area is dense with Neolithic remains: this is just one more to add to the list. And in Ireland there is no tradition of circular irrigation structures, let alone interrupted circles! It could, of course, be a

Well... the comment in question could have been written a lot more clearly. It's not immediately clear to which film the clause beginning "with said film" refers to. That is needlessly confusing.

The Cross Country trains are InterCity trains, just not as prestigious, or as high speed (and not electrically powered). Correcting what I said before, according to Wiki, the Cross Country services are now operated by https://e

It's sad that, as evidenced by the AP1000 Youtube videos, the nuclear industry (at least in Westinghouse's case) appears to have become sclerotic and unable to even hire a dynamic visual communication team. You can't disrupt

The ECML uses Intercity 225 sets, which is a much more prestigious kind of train. Cross Country appear to use the older IC 125 (among others, due to lack of ubiquitous electrification), which is diesel-powered. So it doesn't sound plau

I used to study architecture, and about ten years ago (after drinking too much) decided to visit an architecturally famous but rough estate at night. (It was Robin Hood Gardens.) I walked around and the place was, most significantly, empty.

No, in the case of Zeno, we all agree that the arrow would impact at time t, we just argue that you can take tiny timesteps so you never get there. But after time t, the target has definitely been hit.
