  • I’m not sure there’s any guarantee that it will ever be sorted, since bit flips will be random and are just as likely to put it more out of order than more in order. Plus if there’s any error correction going on, it can cancel out bit flips entirely until up to a certain threshold.

    Though I’m not sure if ECC (and other methods) write the corrected value back to memory or just correct the signals going to the core, so it’s possible they could still add up over time and overcome the second objection.


  • Yeah, I think there is a lot of potential for code analysis. There’s a limited cross section of ways malware can do interesting things, but many permutations of ways to do that.

    So look for the interesting things, like:

    • accessing other programs’ address spaces
    • reading/writing files
    • deleting/moving files
    • sending/receiving network traffic
    • os system calls and console commands
    • interacting with hardware
    • spawning new processes
    • displaying things on the screen
    • accessing timing information

    Obviously there’s legitimate uses for each of these, so that’s just the first step.

    Next, analyze the data that is being used for that:

    • what’s the source?
    • what’s the destination?
    • what kind of transformations are being applied to the data?

    Then you can watch out for things like:

    • is it systematically going through directories and doing some operation to all files? (Maybe ransomware, data scrubbing, or just maliciously deleting stuff?)
    • is it grabbing data from somewhere and sending it somewhere else on the internet? (Stealing data?)
    • is it using timing information to build data? (Timing attacks to figure out kernel data that should be hidden?)
    • is it changing OS settings/setup?

    Then generate a report of everything it is doing and see if it aligns with what the code is supposed to do. Or you could even build some kind of permissions system around that with more sophistication than the basic “can this app access files? How about the internet?”

    Computer programs can be complex, but are ultimately made up of a series of simple operations and it’s possible to build an interpreter that can do those operations and then follow everything through to see exactly what is included in the massive amount of data it sends over the network so that you can tell your file sharing program is also for some reason sending /etc/passwords to a random address or listening for something to access a sequence of closed ports and then will do x, y, z, if that ever happens. Back doors could be obvious with the right analysis tools, especially if it’s being built from source code (though I believe it’s still possible with binaries, just maybe a bit harder).



  • That’s pretty smart, using it for legal documents. If the accuracy is high, it might be nice to just copy paste any tos or whatever to get the highlights in plain language (which imo should be a legal requirement of contracts in general, but especially ones written by a team of bad faith lawyers intended for people they don’t expect to read it and deliberately written to discourage reading the whole thing).


  • The way I see it, sovcits want it for themselves to have freedom to do what they want (which can include imposing on others). “Constitutional” sheriffs want it for themselves to expand their power over others because police can do very well under a fascist system (until they do something against the party and then disappear… Or someone more connected in the party wants their power themselves… Or someone less connected wants their power and can act before the better connections come into play).

    I wonder how many of the ones who want a fascist system for their own power realize how much of a target getting that power puts on them from pretty much all sides.





  • I want to see some videos of salesmen trying to sell touchscreens like they are cars of the future and so great. Followed by the same salesman selling the return to tactile buttons as a big step forward because of how bad of an idea the touchscreens are.

    Most likely the first one will be older, but I bet there’s many that could be lead to do both in the same day by two different people showing interest in the same model but different year of a vehicle.
