Often not elusive bugs, but elusive performance. GPU compilers are hard: Once you've done the basics, trying to do further transforms in a mature compiler will almost always produc…

I agree with the protectionism aspect, to a degree. I also believe the current system does not achieve that in any way.

IMO the problem is that H1B employees are stuck at the employer for the duration of their green card process, and so end up both paid lower and unable to escape abuse. I think a ve…

My prius (2006 model) finally had the traction battery (NiMh) start to loose modules at about 250K miles. It was clearly getting weaker, but drivable at that time. Then Covid hit, …

What plotting libraries work well with Polars?

You can still use the app. You get asked both to have the app get access to the MAID, and get access to location. If this is a problem, it is a problem because you said Yes to both…

My 2019 Kia Niro has some not-worthwhile connected service you can simply say No to. It is then a fully offline car. Assigning ownership involves handing someone the key fob.

Given the conclusions in these articles, I'd expect insurance prices for larger vehicles to be substantially higher, because the underwriters have a large incentive to get this rig…

The drive is inside the car. How do they get at it, and guarantee it isn't tampered with in the meantime?

> Yes but the police can't start occupying my house or deny me access to it because I wasn't home to let them in With a search warrant, they can. You can be kept out of your home u…

The path of least resistance is skipping the search warrant and asking the owner politely, which the article indicates is what is happening. But if that doesn't work, then preservi…

Without first hand knowledge, I'll take a guess: if the owner of the vehicle isn't available or cooperating, then getting access to the USB drive requires opening up the vehicle wi…

Are you using bluetooth headphones? Radio interference is far more common than any scheduling issue.

Correction: There is a big scaleup of capacity that's coming online exactly as BEVs are growing in popularity slower than many previous forecasts (hence lots of press about some ca…

> In the end, this tech just takes control from you. In these difficult scenarios, the alternative photo I'd get using such a small camera without this kind processing would be ent…

If you're interested in more background about one user-visible problem being directly attacked by this new GPU architecture, that could be "shader compilation stutter" (although th…

Even if you're not memory bandwidth bound, leveraging these 2x FLOPs on recent designs is hard, often due to issues like register bank clashes. They are low utilization, but appare…

As you state, GPU latency hiding is basically equivalent to hyper threading, just with more threads per core. For example, for a 'generic' modern GPU, you might have: A "Core" (App…

DOTS/ECS has nothing to do with geometry LODs. Those are purely optimizing CPU systems. Even if DOTS was perfect, the GPU would still be entirely geometry throughput bottlenecked. …

Despite the original post talking about DOTS rough edges, I didn't see anything in that article that actually suggested DOTS was the cause: that would cause CPU overhead, but it se…

Ideally they know exactly how it will perform: Every part of the chip, including the caches, memory controller, and DRAM is implemented in a cycle accurate simulator. There are oft…

Indeed, which is why it is a bit silly to spend so much money on both. And yet the US does.

You're making the single most common misunderstanding of the United State's ICBM defense capability, because you assume the goal is to "defend every city". The real goal is quite d…

Did he make that true via policy changes, or was it an astute observation of what was going to be true given economic realities?
