  • We should have totally called it a unit test.

    So the area for this was used for both training of soldiers and demos for people without security clearances. So it frequently had to be switched between the two. So you get everything setup and ready.

    As a last test you drop the unit in and blam it. Then you go to each system and check the unit status. If it’s ok you are good to demo to civilians.

    A unit test wouldn’t work because it’s a deployment situation and a lot the software wasn’t under our control. A lot of time it was just making sure the DIS HLA gateway was properly configured and entities remapped.






  • I used to work in serious sim. Think using game engines for realistic combat stimulation and training by the army. Systems had to interact and had different jobs rts, fps, driving simulator, etc.

    So they each needed a unit database that was unique to that system. They also usually had a two versions a classified database and a less accurate non classified database.

    A quick way to test was there was a unit type that was always set to invulnerable in unclassified databases. So drop one in the sim and drop some artillery on it. If it wasn’t destroyed you were unclassified.

    Just to warn you there is a lot of lore and it’s changed and been retconned over the last 40 years. That leads to some odd stuff like Leman Russ having a tank named after him.

    It’s also had some major tone shifts from silly (Inquisitor Obiwan Sherlock Cluseau ) to so Grim Dark it becomes Grim Derp. It’s in a sort of midpoint now.

    So look into what you find interesting and if you don’t like it switch sources or topic. Expect things to be contradictory depending on when it was written.

    Here is a good but silly video background to the origin of the orks. It’s still mostly accurate. In 30k the Emperor got hurt and was put on a life support chair. He’s been there for 10k years unable to communicate.

    Premise of this series is they install a text to speech device and now big E can communicate. So they update him on the state of the Imperium and he fills in all the missing history. It’s a fan video and noncannon but lore accurate for when it was made.

    If you want a more serious tone for your lore dump try luetin09 or oculus imperialis. They are to dry for me but pretty good content.

    Also WAAGH is the ork war cry and WAAGH energy is the reality bending field that makes the orks group think real. So red things go faster because red is the fastest color.





  • Common misuse of words. Decimate means reduce by 1/10 not almost completely destroy. Exponential growth. The variable has to be in the exponent if it’s a constant exponent that is polynomial growth. Gaslighting isn’t just lying. It’s making someone belive that they can’t trust their own memories or experiences so they believe you despite evidence to the contrary.




  • Even the replacement and most modern remotes (with an LED at the tip that you have to point at the device) use pretty cool tech.

    Usually to send data you want a data channel and a clock channel. When the clock changes say from high to low you read the next bit in the data channel. With one LED to send info you need to combine them.

    For transmission that’s easy. You make the low to high change at a fixed frequency. For the high to low change if it’s a zero you make the high to low change 1/3 the way through the cycle. For a 1 you make the change 2/3 the way through the cycle.

    On the receiver you you sync up a signal at the same frequency rising with the start of the transmission at a 1/2 on 1/2 off. You look at the data when the reference falls 1/2 the way through the cycle.

    If a zero was sent the line had fallen at the 1/3 and it is a zero. If a one was sent the line doesn’t drop until 2/3 and it’s a one.

    The trick is how do you get a signal at the same frequency and in synch. You compare the transmission frequency revived to the frequency of a voltage controlled oscillator. If it’s slower you up the voltage and increase the frequency if it’s faster you lower the voltage and lower the frequency.

    You similarly use a phase detector to determine if they are in phase slightly boosting the frequency until they are in sync.

    This system is called a phased lock loop (pll). All this so you don’t have to getup to change the channel. The same sort of system is used for reading data from the magnetic disk on a hard drive.
