What is the metric of success. Iran wants the US to stay out of the region. Nothing about our response to 9/11 suggests that that is how we would respond to an attack on our soil.

I'm just going off (English language) reporting, not the text itself. But I don't see anything about the new law invalidating drunken consent.

LLMs (at least in their current form) are proper neural networks.

This is where TPMs, measured boot, and remote attestation come in.

You can run whatever kernel you want, but if it is not an approved kernel, you wouldn't be able to attest to running an approved kernel; allowing whatever DRM scheme the developer put in to active.

I believe this is how the higher levels of Android's Play Integrity system work.

As with all open problems in computer science, we solved these back in the 80s.

I've used it a fair amount for memory mapped IO where the hardware defined bitfields. It is also useful when you have a data format with bitfields. I'd say it is also useful when your data does not respect byte boundaries, but the only time I've run into that involved the bit order being "backwards", which means that I still had to bittwidle things back together.

From a performance perspective, a cache line is only 64 bytes. Space in registers, low level memory caches, and memory throughout are all limited as well.

You lost me at return oriented programming. Getting something working out of that is way more difficult than doing it out of vib coding. (Way more impressive though)

I've had a couple of issues like this:

  • Wireless mouse has a flaky connection. Turns out the issue was the USB port it was plugged into (probably RF interference as other devices worked fine on that port)

  • We had a couple of radio receivers in a server rack. The scale of the project had shrunk over the years, so what used to fill up 2 racks now only half filled them (mostly because of upgraded components becoming faster and smaller over the years). Another project needed needed some rackspace, so we reracked everything into a single rack. When we were done, we found that one of our receivers couldn't get a signal, and another would lose it regularly. Checked over all of our connections and the antennas, but everything seemed normal. Turns out something in the other project was blasting out RF interference.

  • We would occasionally need to manually move data on/off a server using a USB2.0 hard drive. This worked fine for years, until one day we had a server that would randomly disconnect from the drive a few seconds into the transfer. Tried different ports, same issue. The drive itself worked with all the others, so we decided the issue must be with the server. We swapped it out for a brand new one with plans to send the old one back for warranty repairs. Except the new one has the exact same issue. Both servers came from a newish batch from the OEM. Turns out that the earlier versions had a hardware "bug" where the USB ports would source more than the 500ma allowed by the spec. Since they fixed that, our drive would trigger the current limit during sustained use and temporarily depower the port. Solution: get a USB Y cable and power provider power from a wall block

  • I had a mouse that would double click (or more) when you pushed the button. This was pretty obviously a hardware issue, but I figured I could just tell the computer to ignore double clicks that happened "too fast" and avoid needing a new mouse. In theory that should have worked, but the input stack on Linux turned out to be a giant web that I couldn't figure out, so I ended up opening the mouse and soldering on a random capacitor I had lieing around.

  • We had a laptop with a dead monitor that would mysteriously work at times. It turns out that most of the time, it was sitting on another laptop (of the same type). Those laptops had a magnet latch to hold them shut. It turns out that said magnet also was used as part of a "laptop closed" sensor that would disable the monitor, and the bottom laptop would trigger the sensor in the top one.

And put some guidelines in the road to assist with self driving. Maybe make them out of metal for improved durability. Then swap out the rubber-wheeled tires for some more efficient and less poluting conical metal wheels since we don't need to worry about them running on asphalt anymore.

Oooh. And as long as we have multiple carriages connected, we can add a walkway between them. Then instead of all of them being for passengers, they can subsidize the cost by having a car dedicated to selling snacks, or other items. You can literally buy your morning coffee from the road!

A bit more context for that quote:

calling for a one-state solution without specifying equal rights for all people; Jewish in particular.

The "one state" in the one-state solution is Israel, which currently views itself as an occupying power, and has Jewish Supremacy enshrined in her basic law (essentially constitution). Jews are not the group that is at risk in this scenario.

I still burn DVDs. Ever since USB storage was deemed "not secure", they are the easiest way to get data into and out of sensitive networks.
