  • The emulator in had could do tool path correction, and tell you when you would crash. And they were working on lights out automation when I left, albeit classical programming, not AI. Was easier for us given we only supported a very limited number of machine models though.

    I suspect, and you’ll know better, but these guys dont know shit about machining, which is why they are coming to you. I suspect that they have no idea how large the problem space actually is, and they are just going to try to brute force an AI solution.

    And I dont think that is viable for machining.

    Whether you do this correctly or not won’t change that they dont know what they are doing. My guess is you can give them exactly what they ask for, and after a month or 2 it won’t work, and theyll ask you to redo it all slightly differently, and youll go through that cycle until they run out of money.

    You may as well take their money. And be smart about it. You need a top end dSLR camera to record accurate footage, get them to send you one. You need a top end PC and a high res and high framerate monitor to process the footage.


  • 64GB sounds plenty, but is there perhaps a slow men leak in a process?

    Leave your PC running, run this in a terminal, and leave it:

    watch -n 3600 "date >> logfile.txt; free -m >> logfile.txt"
    

    Its a script that writes the time, and then the memory stats to logfile.txt.

    Let it run until the PC stops responding, and then leave the PC a couple more hours.

    When you reboot, have a look at the logfile, and see if the memory was growing at all. Also see if you get any date stamps after the PC stopped responding, because that might mean it was not fully crashed.

    If it is a memory leak, the next step would be narrowing down which process.



  • Surely there are already generic CNC emulators? I had an internship 15 years ago for a CNC company that had an emulator for their tools. I also know it was leaked on the pirate bay, which everyone thought was hilarious. Pirating the emulator is worthless without the very expensive CNC machine.

    I really doubt there is anything an AI can learn from your videos, and I suspect the AI company has no idea what they are doing. Take the job, get the money (in cash), and wait for them to crater. Dont be surprised if the job dries up long before the term though.



  • Yeah, that’s exactly my point. I am not a parent, but in my opinion, it would be better to allow the use of whatever platform is the default, maybe provide an alternative, and give the child an age appropriate understanding of what using Instagram/Whatever means to them. “You can use it, but don’t say anything private like our address, because your private messages can be read by the company. If you need to say something private, use signal/matrix/whatever else, because that’s safe.”. Maybe if your lucky they can pass that knowledge to their friends as well.

    Kids are walking privacy violations at the best of times anyway, education needs to start early.







  • Its important to remember that the vulnerabilities always existed, we just know about them now. We have no idea how many of them were being quietly exploited before now.

    There is no point being mad at AI for the avalanche of CVEs, if anything we should be mad ourselves for not prioritising security review of the code. Many of these issues probably could have been found before AI if we as an industry were willing to spend the resources doing the audits. But we werent willing, and now we have to pay for our sins.




  • That doesnt change anything about my original point. They are conflicting missions, whether you add certain or not.

    And no matter what you call it, backdooring ghidra defeats the point of both, it means no one will use it, which allows malware to run rampant. (Ghidra was released during the height of the cryptolocker craze, it allowed reversing those crypto lockers to be done by anyone, effectively neutering many of them).

    And when it gets caught its immediately attributable to the malware division, which they dont want either.

    There is zero point backdooring ghidra. Now XZ? *sshole? Thats the level of sophisticated backdoor I would expect from the NSA.


  • Only true if they can abuse the backdoor, if its tied to NSA infrastructure (which a competent backdoor would be), they couldn’t use it. There is also precedence, the Germans didnt hesitate to publicise that Angela Merkel’s phone was hacked, they could have used the malware to feed false information instead. Stuxnet was exposed to embarrass the US/Israel.

    Cyber security companies would also have no qualms about publicising it. Finding a NSA backdoor would put them on the map, and they have no use for a backdoor.



  • Go to any cyber security conference. Check out the CTF teams, Ghidra is used everywhere.

    Can you prove that there is a backdoor? Remember that it is freely available, and if China, Russia, NK or any other nation state could find a backdoor, they would be shouting it from the rooftops to shame the US.

    I dont doubt that the NSA could have seeded a backdoor in an open source project, but I very much doubt they would sign their name to it…
