  • If anyone is really curious about how INS works https://en.m.wikipedia.org/wiki/Inertial_navigation_system

    Also this Air Force training audio REALLY clears the subject up: https://youtu.be/VUrMuc-ULmM

    The Missile Knows Where It Is

    Transcription for the audio is as follows:

    "The missile knows where it is at all times. It knows this because it knows where it isn’t. By subtracting where it is from where it isn’t, or where it isn’t from where it is (whichever is greater), it obtains a difference, or deviation. The guidance subsystem uses deviations to generate corrective commands to drive the missile from a position where it is to a position where it isn’t, and arriving at a position where it wasn’t, it now is. Consequently, the position where it is, is now the position that it wasn’t, and it follows that the position that it was, is now the position that it isn’t.

    In the event that the position that it is in is not the position that it wasn’t, the system has acquired a variation, the variation being the difference between where the missile is, and where it wasn’t. If variation is considered to be a significant factor, it too may be corrected by the GEA. However, the missile must also know where it was.

    The missile guidance computer scenario works as follows. Because a variation has modified some of the information the missile has obtained, it is not sure just where it is. However, it is sure where it isn’t, within reason, and it knows where it was. It now subtracts where it should be from where it wasn’t, or vice-versa, and by differentiating this from the algebraic sum of where it shouldn’t be, and where it was, it is able to obtain the deviation and its variation, which is called error."



  • Who’s educating the parents on what’s going on in the games? The casinos? The slot machines? The sports betting apps?

    Where do the average learn about these things?

    All well and good if you are fairly well educated and know about some of the psychology going on. But damn I do not have any hope for the next generation raised on tick tocks as the GOP dismantle public education.

    It’s going to quickly get like Idiocracy in here all the while bystanders will say, but the parents working two minimum wage jobs to put food on the table and a roof over their head should have taken responsibility for their child!

    People fall through the cracks and we all as society benefit when we are responsible enough to try to make sure the cracks can’t just swallow you whole.

    Shit, I’ve got 3 university degrees and top certifications for my specify IT field and wouldn’t know much about this topic if it weren’t for Sout Park Freemium Isn’t Free.

    We can’t depend on being educated or involved with children to protect them from 24/7 365 always online dopamine addiction to compulsion loops.


  • I highly doubt I will have the time to try all the new research drug-games my children acquire access to. Better stick to first party Nintendo games-drugs.

    In all seriousness, PBS kids apps on mobile go hard, work on any device, and are fairly educational while being easy to use and fun enough to hold attention while being completely FREE.

    We’ve paid for ABC mouse but the whole fuckin thing reeks of slot machine pokie stimulus while the puzzles and games crash often. The only thing that 100% works all the time is the store to exchange your “tickets”

    Abc mouse is the highest rated most teacher recommended app and it’s fucking awful.

    My 3 year old has gotten way more out of free software than any pay software that’s littered with addictive BS.

    I would recommend:

    GCompris

    Khan academy kids

    Learn to read Duolingo ABC

    PBS anything

    Nuclear weapons are expensive and complicated to maintain. The military has been bitching for many years that the price to maintain old nuclear munitions is rapidly increasing.

    Instead of seeing this as working as intended, and trying to get everyone to agree not to develop new nuclear weapons… The military strategists decided that since China was making 500 new nuclear weapons we needed to make new ones too and pulled out of the agreement with Russia not to develop new nukes.

    I would have thought that if it was hard for us to maintain the nuclear weapons with a massive budget that Russia might fail at that task. Which would be good for everyone.

    But there’s always been more money in star wars and missile defense then diplomacy.




  • We’re you refered to physical therapy after breaking your foot? Or are you able to see if insurance will pay because your mobility has been reduced?

    I had several injuries in the military that left me unable to stand, walk, drive a car, or balance for very long. With the help of physical therapy I was eventually able to walk properly, then after some time I was able to take a ride to work a job where I was sometimes sitting but often standing. Eventually I was able to work and exercise enough that I got all my balance and mobility back.

    Having public transit helped me when I still didn’t have enough fine motor control to operate a pedal and brake.

    Not everyone is on the same journey, but please see if you can access physical therapy. Please advocate for not just healing but making yourself whole.


  • They will trade in the Confidentiality and Integrity for just Availability.

    When something like a hack finally drops the availability they will be forced to act.

    They will never do a pentest tho.

    Same story all over from government, small companies, all the way up to medical in big corporate hospitals and systems that could cause harm to human life.

    Security is at most a checkbox somewhere that just gets checked regardless of the true state of the system. If it still works don’t fix it.
