Yeah, Discord is not a privacy preserving service in the slightest. Honestly I'm only using it because of the network effect at this point.

Do you have a source for that? I am unaware of any modern hard drives that support reading individual bits; the minimum unit of data that can be read is generally one sector, or 512 bytes. If the sector fails to be read, the drive will usually attempt to read it several times before giving up and reporting a read error to the PC.

Data recovery companies can remove the platters from a damaged drive and put them in a working drive, as long as the platters are in good condition, preventing further damage. (If the platters themselves are damaged, you're screwed either way).

If your data is really important, you should send it to a reputable data recovery service. Using the drive any more (even with a tool like SpinRite) risks further damage.

If every one of those users uploads one 10MB file, that would be two petabytes of data. At S3's IA prices that's $25k/month. And people are uploading far, far more data than that.

If anyone wants to actually run this, here ya go:

          #include              <stdio.h>
      short i=0;long          b[]={1712,6400
    ,3668,14961,00116,      13172,10368,41600,
  12764,9443,112,12544,15092,11219,116,8576,8832
,12764,9461,99,10823,17,15092,11219,99,6103,14915,

      10086,14929,79,10868,14464,12357};long
        n=9147811012615426336;long main(){
          if(i<0230)printf("%c",(char)((
            0100&b[i++>>1]>>(i--&0x1)*
              007)+((n>>(b[i>>001]>>
                7*(0b1&01-i++)))&1
                  *main(111))));
                    return 69-
                      0b0110
                        ;}

Bonus points if you can deobfuscate it!

They do still have to cater to desktop users, so I imagine accessible websites for those platforms will exist for many years to come.

GrapheneOS can be rooted, though they don't recommend it as it's bad for security. For an archival device I imagine security isn't a big concern.

I'm tired of people ascribing any sort of intelligence to AI. It's not thinking, it's not seeing you as a threat, it's just predicting a probable response based on its training data.

Now that's an interesting idea; basically external regenerative braking. Not too helpful on a highway, but I suppose it would be useful in the situations you described.

That's a fair point, a device could theoretically harvest energy that would have otherwise been wasted, and that would be green energy. I imagine a wind system could work, though it might result in cars experiencing additional drag from slower wind speeds.

However, the piezoelectric generators mentioned in the article quite clearly do not use waste energy. They compress under the weight of the cars, turning a small amount of gravitational potential energy into electricity. That energy must be made up with extra fuel.

Finally, even if all of the vehicles on the road were powered by clean electricity, it would still be a useless system. Piezoelectrics are nowhere near 100% efficient, so you're just taking electricity from the vehicles at a loss.

Last year the California Energy Commission posted the results of a study aimed at assessing efficiency of deploying piezoelectric systems to generate clean electricity from roadways.

“Based on the laboratory evaluations and road tests, the application of the piezoelectric energy harvesting system in one lane of a one-mile-long roadway has the potential to generate 72,800 kilowatt-hours of energy per year,” the team reported.

How is that clean energy, in any sense of the word? Any system that gains some energy from a passing car must necessarily decrease the (kinetic) energy of the car by an equal or greater amount. And the vast majority of cars get their kinetic energy by burning fossil fuels. Sounds like a more expensive, less direct, and less efficient version of a gasoline generator.
