> In this Gemini-reconstructed scene, ...

I'm generally pretty pro-AI, but I find this icky. Of course, I wouldn't have noticed except the whiteboard drawing seemed not quite right, so I'll probably be fooled in the future.

A fair point...

I thought the bug was a missing check for the COW flag, but looking at it again it seems it was missing both setting and checking the flag.

In CHERI, for example, pointers have permissions. The pointer to the COW memory would not have the "write" permission.

I could be misunderstanding the bug, of course.

The parameters in the original gpt-oss-20B model are "post-trained with MXFP4 quantization", so there just isn't much to gain by quantizing to Q8. If you look inside the Q8 model, most of the parameters are MXFP4 anyway.

Though, looking inside my "gpt-oss 20B MXFP4 MoE" model, it looks to also be quantized the same way as the Q8, so that was probably an overstatement on my part.

Still, the Q8 is 12.1 GB and the FP16 is 13.8 GB. Not the ~1:2 ratio you might expect.

As of b8966, it is still not great.

Edit: I've no idea why one would use gpt-oss-20b at Q8, but the result is basically the same:

  | model                 |      size |  params | backend | ngl |   test |            t/s |

  | gpt-oss 20B Q8_0      | 11.27 GiB | 20.91 B | SYCL    | 999 |  tg128 |   44.02 ± 0.05 |
  | gpt-oss 20B Q8_0      | 11.27 GiB | 20.91 B | Vulkan  | 999 | pp2048 | 2022.24 ± 6.97 |

Hopefully, support for the B70 will continue to improve. In retrospect, I probably should have bought a R9700 instead...

Compared to a B70, a 5090 is 1x the memory with 3x the bandwidth at 4x the price. Yeah, the 5090 is better, but you're paying for it.

Never buy another ebook from Amazon, sure.

Never buy another Kindle? I keep mine in airplane mode all the time and sideload all the books/papers I want to read. It works practically just as well as when I bought it. Why wouldn't I buy another? If Amazon makes a Kindle with color at 300 PPI, I will.

Sure, proper EPUB support would be nice, but if I need that I can jailbreak and install Koreader.

If there's another device with comparable hardware/software/battery, I'd consider it. AFAIK, Kindle still has the best standby battery life.

> “The outbound and cross-bound DDoS attacks can be just as disruptive as the inbound stuff,” Dobbin said. “We’re now in a situation where ISPs are routinely seeing terabit-per-second plus outbound attacks from their networks that can cause operational problems.”

ISPs are starting to feel the pain, so perhaps in the near future they will do something about it.

I, too, am jealous of China's high speed railroads. However, on the whole, China has overbuilt their infrastructure, and that may not look so smart in 40-50 years when the maintenance bills start coming due.

The Freestyle Pro is almost a good keyboard. The Esc and function keys are all offset to the left by one key compared to a standard layout, which drove me nuts. I have a Freestyle Edge RGB now, which I like much better. (Though I replaced the wrist rests with some from Goldtouch.)
