I see this comment on every single LoRA post despite the vast majority of posts being about LoRA not LoRa. Can we please stop beating this dead horse?

New comment by jorlow in "Unsafe and Unpredictable: My Volvo EX90 Experience"

jorlow — Tue, 22 Jul 2025 23:15:00 +0000

I had a horrible experience with my XC90 plug in hybrid. It took months of back and forth with the dealership and thousands of dollars to find out that it's dangerous behavior (refusing to stop without flooring the break with all my might) was due to a wire harness a critter had chewed on. Very similar response from Volvo in my case. No accountability and very low competence. Avoid Volvo.

It's basically a blob in space. When you have millions of them, you can use gradient descent to minimize loss between them and source images.

Does this compete at all with openAI's triton (which is sort of a higher level cuda without the vendor lock in)?

I wonder why browsers don't show a bit of UI that it's in compatibility mode and give a way to disable (or enable for other domains for dev/testing).

If a browser has too many compatibility issues, users will switch away. Outreach to the sites in question takes time and is often unsuccessful. Quirks is the pragmatic answer.

It doesn't really add up. The schedule was always uncertain. Why not postpone? Why a big announcement only a year and a half ago? Seems pretty cruel to all the people selected to take the trip...

Sure, it's weaker in telephoto. (I rarely shoot beyond 85mm.) Fwiw I never use portrait mode -- too artificial. The main lens still gets pretty nice shallow DOF tho

I have a pixel 8 pro and a canon r5 and honestly, unless I'm shooting at f2.0 or less, I generally prefer the pixel images. Not to mention they're instantly sharable.

To keep it "tiny". (IIRC geohot started it because he thought pytorch and others were bloated and a simple ml framework would be inherently better)

Note llama's feed forward is a bit different too:

  self.w2(F.silu(self.w1(x)) * self.w3(x))

I.e. the nonlinearity is a gate.

On the other hand, you have to be pretty sick to qualify for such extremely experimental procedures. And transplants are pretty intensive operations even when someone is otherwise healthy (and getting human organs). It doesn't seem farfetched for unrelated complications to indeed be the cause of death.

jorlow — Fri, 03 May 2024 17:02:54 +0000

I too feel a bit worried about AI making mistakes, but the thing is that a doctor rushing or an assistant can (and do) make mistakes too. These are all just cost vs quality of service tradeoffs. From my experience (having been in and out of hospitals a lot in the last year) it wouldn't surprise me if AI, even with occasional mistakes, would still be a net improvement in overall quality of care and outcomes.

Sure, but OpenAI was not founded (or initially funded) to be an AI product company -- which is OP's point.

For me it's this + going overboard on minimalism (speed only on center screen, turn signals now buttons, wiper controls on touch screen). It's a shame because there's a lot to like about the model 3.

The article says "patients must undergo a preparatory treatment with a chemotherapy drug to remove any native stem cells that might remain in their bone marrow." It doesn't make much difference to the patient if it's the Lyfgenia itself or the chemo drug, if the chemo drug is a requirement. Right?

I think you're describing traditional scheduling. The point is that sometimes overheads from cache thrashing and context switches are worse than just spinning.
