Comment Re:10 things AI won't do (Score 1) 331

If human judgement is needed, it's far easier to train someone to decide whether an alternator armature is worth refurbishing than to rebuild an engine. Then you sit them down to do nothing but screen alternator armatures all day.

And you feed pictures of those armatures and the human's decision to the AI so it can learn to do the job cheaper and faster.

While it won't deal with switching the USB hub, have you considered using Synergy to share mouse/keyboard between the computers? The way it works is you lay out your displays and computers, and tell it when you go off the right side of monitor 2 of PC 1, pass control to monitor 1 of PC 2 and the mouse (and keyboard input) appears there. As a bonus, it can transfer the clipboard between computers too.

I use Cookie Clicker as my benchmark. Set it to Christmas and turn on audio. Does the reindeer sound play before the reindeer leaves the screen? On Chrome the deer was gone by the time the jingle quit and almost gone by the time it started. On Firefox, the deer was halfway across the screen. Click a wrinkler. Does it respond to every click? Triple click one. Did it pop? It should, but on Chrome it sometimes takes four-five clicks. Get a cookie storm. Does it even react to you clicking the cookies before they disappear?

I'm on Linux with a 4k monitor so maybe there's something with Chrome in that environment, but Firefox does reasonably well.

Getting to the point where I'm going to have to dig out my old VIA-powered Wal-Mart PC to do my banking and such on to ensure security from hackers dropping javascript into my browser.

At the very least, the slow speed means I'll realize pretty quickly when someone is trying to use it to mine cryptocurrencies.

mov rax, kerneladdr is the instruction that page used as the exception, which is a page fault and a memory access violation that should segfault. What I was missing is that non-root users can actually trap SIGSEGV (which I should have realized, otherwise SIGSEGV would terminate debuggers too), though the stack overflow pages on this definitely demonstrate it's not simple to come up with a trap that isn't "crash into debugger" or "exit".

That's exactly what happens.

cause a page fault, and then

Write a short little helloworld.c that causes a page fault and then prints "Hello World". Let me know what happens to "and then" when you run it as a non-root user.

There's another piece of the puzzle that is still missing/not being talked about. I suspect that this exploit *only* works meaningfully when done in a virtualized guest with a hostile admin/root exploit. My suspicion could work with a root exploit without a VM, but you're already root so why?

Based on this link from Hacker News: https://cyber.wtf/2017/07/28/n... and the linked email/patch from AMD, it looks like what happens is that AMD checks memory permissions up front before allowing an instruction into the pipeline, while Intel made the memory permission check as a later part of the pipeline, apparently after the memory was accessed and inserted into the cache.

Comment Re:Single Payer Health Care is Great ! (Score 2) 486

You don't understand how insurance works

The real problem is that "health insurance" isn't insurance, it's just a means for moving money around. Unless you wander off into a forest and die or fall into a volcano or a vat of molten lead, there is a 100% chance that you will require medical care. As for pre-existing condition clauses being required, imagine if Homeowner's insurance had "fire" as a pre-existing condition that followed you for the rest of your life. You have one grease fire in the kitchen and you can never get home insurance again. Unlike a house or a car, you can't yet replace a body. Once your roof is on fire, it's on fire forever. Except that with health "insurance" we expect insurance companies to keep replacing the roof as it burns and then watch the new roof burn too.

The REAL real problem is that modern top-of-the-line healthcare is incredibly expensive, and we're losing cheaper older technology that was generally "good enough", largely because of the enormous opportunity cost of manufacturing an older generic drug versus manufacturing a new patented drug. Good luck finding a doctor under 60 with the knowledge and mix to make a plain old plaster cast, because charging a % overhead on a $1000 fiberglass epoxy cast is way more profitable than on $5 worth of plaster of paris. Plain old insulin is another one that suffers from constant improvements - each slightly more expensive than the last.

are expensive because the vast majority get their insurance through their place of employment. Like any product, if demand is low, not many companies will provide it and it will cost more

Like "any" product? Are you sure about that? Someone is at the grocery store sitting there adjusting the charges as you browse because you pay more for the exact same apple because you're self-employed than if you worked for Ford? I'm sure you imagine that a Ford employee's apple must somehow be less nutritious or valuable than a self-employed person's apple, but I'm not seeing the difference from here. Generally employer-provided insurance is cheaper because they pay some portion of the premium for you (and get a tax deduction for doing so). That's why people get sticker shock when they leave the company and sign up for the COBRA extension: It's the exact same insurance but now they have to pay 100% of the premium themselves.
