It could be literally automated. And I'm talking about while they were still minutes away on approach, not during final landing.

And yet I am! Care to elaborate?

I mean, complete ethical nihilism is one way to try to avoid losing this particular argument, but I don't think you'll get many people to agree with you on it.

Maybe ATC could be expected to revoke landing clearance on extremely obviously unstable approaches? I wonder why that didn't happen.

They made a series of at least ten (and that's kind of charitable) this-must-never-happen mistakes that likely rise to the level of extraordinary criminal negligence, including ignoring checklists, alarms, configuring the plane for lan

The tokens spent to find the vulnerabilities will cost money, and the attackers will usually find themselves more financially incentivized to spend money on finding the vulnerabilities than the defenders.

If it was a mechanical keyboard with that case instead of an entire computer they could charge twice as much for it.

Not sure about that, V100s are all selling for less than $1k despite being 24-32GB VRAM around 1TB/s memory bandwidth, which is the same price point that 4090s and 5090s are commanding $4k-$5k for. Hardly hotcakes.

Why not? The web uses TLS, how's it different security-wise compared to a package download?

Does anyone know how to get this working with Claude Code via llama-server? I'm getting a jinja template error about the system prompt not being the first message.

Hm, I have a 4090 as well, and: $ build/bin/llama-server -m Qwen3.8-27B-IQ4_NL.gguf --mmproj mmproj-BF16.gguf -c 170000 --parallel 1 -ngl -1 --cache-type-k q8_0 --cache-type-v q8_0 -b 1024 -ub 512 --flash-attn on --no-context-shif

Does it not use Metal, on macOS? Would it be faster if it did?

It's a very conservative warning. The application does not perform writes, so the application doesn't actually wear your SSD at all. The rest is just application-independent general hygiene.

You still have a core misunderstanding. Only one layer of weights is required in memory at a time. A forward pass can be over-simplified as a matrix multiplication of each layer, one at a time. There is no swapping of working RAM. We'r

by cjbprime 3mo ago
Both sentences are likely wrong. It's a written lifespan (technically an "erased" one), not a read lifespan. The weights are only needed from disk read-only. And Mac NVMe interfaces are surprisingly fast. Edit: Oh, I thin

I've got access to a 192GB RAM Mac Studio, which is below the stated minimum RAM. Can swapping off fast disk be used to make it work out, especially since it's MoE?

Inference (not training) is bottlenecked by memory access speed, not compute. Having special hardware wouldn't make it faster unless you somehow found a faster memory controller than the GPU has.

I don't agree with the "twice". A frequently performed manipulation like the fuel cutoff (usually performed after landing) collapses down to a single intention that is carried out by muscle memory, not two consciously selecte

The prelim report states these pilots were indeed breathalyzed before takeoff.

I meant philosophical toggle switches, not physical ones. The gear can go between down and up. The fuel can go between run and cutoff. Given enough practice, the brain takes care of the physical actions that manipulate those philosophical t

Now I'm trying to remember if I've ever picked up my razor and accidentally begun tooth brushing motions with it. Probably! More relevantly, you seem to me to be unduly confident about what this pilot's associative triggers m

Sometimes? If you have enough altitude to trade for speed then after the cutoff you could glide to a hypothetical miraculously-placed runway right in front of you, vs. having fire quickly consume the entire plane if you don't cutoff..

It's not that rare, and there are institutional factors (such as seeking treatment for psychosis being career-ending for a pilot) that incentivize serious pilot mental health crises being untreated.
