saw 30 new posts, figured something good must have happened yep lay off the grass dude. you are the perfect stereotype of every stoner who thinks weed makes you brilliant just with a shaky understanding of math instead of a shaky understanding of politics

welp i guess that's over with so anyway, i got myself a spare time project guy was selling this old tektronix oscilloscope on craigslist, apparently he didn't actually know what a scope was because he thought it worked, but when i showed up to test it out, it did not so i gave him twenty bucks for it to see if i could fix it myself here's what the guts look liks  i've never touched a tube in my life and i am very scared should i just sell the tubes to idiot audiophiles or should i do this oh yeah here's what a working one looks like  it's like 20 pounds and the screen is 3" in diameter, lol

01011001 posted:timecube is a valid idiot spare time project right a couple of my friends have gene ray's phone number and one day they decided to call him up and get him to personally explain his theories about time, the jews, and 4-sided equilateral days. they tell me that he's a friendly mostly-coherent guy who's very happy to talk about his weird-rear end ideas, but now they won't tell me his number b/c they feel ashamed at exploiting a mentally-troubled senior citizen. i want to talk to the dude before he kicks it  lol at everything happening over the past page and looking forward to seeing Mr SuperAwesome with the nobel prize in stoner programming or w/e

One thing that you could do would be to pull out the tubes ONE AT A TIME, look them up for pinout and check to make sure you have: -continuity between the heater pins -no continuity between either heater pin and the cathode -no continuity between the cathode, any grids, and the plate you're probably going to find dried out caps, too, but stage 1 is to test tubes please be very careful the guts of that box really could put you in the ground one hand in your pocket at all times* and move slowly and carefully *this is so that you don't create a path for HV across your chest with both arms. better it go in one arm and down your body to ground

 Even when unplugged, lethal voltage can be stored in the capacitors IIRC

I didn't know you could get them for $40. This was way more educational, though.

yeah i was a bit baked for some of it but i wrote it all down and git commited the insanity for later and it seems p useful starting from 3 axioms and one hypothesis: - axiom of inherent uncertainty (nothing u know is ever truely real or knowable!) [i made this one] - axiom of choice - the empty set - euler's formula with a small tweak using -i instead of i (this makes the power series of i repeat with periodicity of 4n, representing our 4 initial things) and using that as the basis for a phyics-inspired programming language (i.e. replicating a physical system) you can get some insanely powerful results. this is all from complete first principles, remember. Feynmann had a great method for lazy dynamic analysis: always start from the principle of least action (which is lambda calculus, functional programming). so then i plugged in some numbers and started getting 3d representations of Stepehn Wolfram's cellular automata from his New Kind of Science book. Now, I'm sure down the line primes features heavily, which brings in Ramujan's infinite series, and power series of primes as the coefficients of the Reimann Zeta function (using the 4 vars we have already plus a state function that depends on times), gives us a pentagonal number which is what that fuckin crazy math depends on. Interestingly tho when u look at the structure of those formulae they're actually super elegant; i'm 99% sure they represent pertubations from a point moving backwards and forward in time (think Feynmann diagrams) Also I don't like C++ for the same reason Linus doesn't - its ugly horrible and easy to gently caress up in. C is elegant and u can do the same poo poo if ur smart and need to. Otherwise just use python or C# unless u NEED to (haskell/erlang for spergin) anyway here's the important bit. pretty pictures

i think the main initial error when inventing computahs and turning machines is overlooking uncertainty. reality is ternary not binary - there is "YES", "NO", and "WTF??? IDK"

it's not like it's moronically stupid. the solder mask will stop you creating shorts 95% of the time. it's just the auto-router doesn't seem to make the best use of space, and will do things like route really close to a component, or between the legs on a chip when there's another route available. its main priority is to reduce the number of vias (the plated holes that join the traces on one side to those on the other). on big densely-routed boards that matters because you often have to pay the PCB manufacturer extra if you exceed a certain number (say 500), but for small boards with 10 components it still assumes routing really close to component pins is better if it reduces the number of vias from 4 to 3.
