as a side effect, it’s a phenomenal accountability sink. people almost forget that usaf can make entirely human-made fuckups https://en.wikipedia.org/wiki/Amiriyah_shelter_bombing

i think you can say that at least some people of iran already turned against their government, except those with guns. historically the parts of strategic bombing that worked were targeting of military leadership (in progress), communications (?), weapons storage and manufacture (in progress), energy production (no signs so far). not sure if there is any plan beyond strikes, leave it to them to turn operational success into diplomatic failure

i had no idea that you can buy anti-ship missiles in any corner store. not sure how do you make sense of how both of these militias mentioned decided to do nothing after the guy signing their checks and sent them weapons was killed

last time i’ve checked, wandel durch handel style approach was determined to not work as intended, not that it matters in this case anymore

i also think that americans are currently allergic to boots on the ground involvement* so it’s not likely. my best guess is airstrikes only, then ??? then i guess they expect regime change to materialize out of thin air. only time will tell

* unless it’s not theirs, but for example kurds, this way they don’t care

i don’t give a shit about sam harris. if iranians were broadly fine with theocracy, there wouldn’t be 30k+ dead protesters last month, or major protests every year for a decade. like every other country on earth, you can expect that iran secularizes, except that apostasy or conversion is capital offense, or any significant dissent for that matter, so any survey unaffected by self-censorship would be hard to conduct

there is some reason to think this way. also keep in mind that a segment of that anti-americanism was funded by sales of iranian oil. not all of course, but houthis wouldn’t be a thing without it, or large parts of hezbollah, for example. of course what people want and how it shakes down after the bombs drop is different thing entirely, i guess we’ll see, eventually (i assume that decision to strike was already made)

ai is crypto 2 episode 373275

there was chrome (and firefox probably?) extension that went through your all fb liked pages and unsubscribed from them so that when it’s done timeline is gone entirely. fb went after its dev, removed that extension and banned him forever because it kept people off fb https://www.businessinsider.com/facebook-bans-unfollow-everything-developer-delete-news-feed-2021-10 doing this all manually still worked back then, not sure about today

Facebook’s letter took him by surprise, he said, adding that Unfollow Everything had only 2,500 weekly active users and 10,000 downloads.

“It was definitely growing, but it wasn’t huge,” he said.

“Apart from that I just very much saw it as something that improves the Facebook experience for Facebook users,” he added, saying he got “amazing feedback” from people saying they “were using Facebook in a way that was much healthier for them.”

a hellish vision has been revealed to me

potentially a common one, but we’ll only know after password leak from somewhere

i was thinking more like, thin external plastic shell and empty cells inside, perhaps with another thin plastic shell on inside, and internal metal shell (on plastic support?) fitting in snugly, for mechanical stability, idk 3dprinting

keeping leads short and nonmagnetic (dramatic reduction in skin layer depth) would be a good thing because of losses, but the longest object in capacitor would be just capacitor plates, and either way in wavelength terms it’s rather small. more precisely you can model it as open transmission line stub with some weird and low impedance, but it’s so small that you don’t have to. you can also make capacitor shorter and wider, or even add more layers like how vacuum variables are made. in nesting design you can get taper effect just by making inner layers longer

Found a piece about RFI and baluns, http://audiosystemsgroup.com/RFI-Ham.pdf multiple turns on ferrite aren’t really an option for VHF and up, ended up ordering extra beads (non-split)

The dielectric between the plates in this case is 0.4mm of ABS plastics (+ a bit of air in the 3d print layer lines).

in terms of losses, PP or PE is a bit better than ABS, teflon or FEP is a bit better than PP, but air is superior to either (this is part of the reason why foam coax is a thing). not sure which ones are printable, or whether it’s practical at this size, but try to introduce as many voids as possible (perhaps requires larger thickness of dielectric). it doesn’t matter much in your case, because of low power (warping of plastic because of excessive heat is probably not a problem). if your coax has solid dielectric, then by introducing enough air in 3d-print your variable might become less lossy than that

The Capacitors allows my 80cm diameter loop to tune from 20Mhz to 37Mhz. Sweeping the whole range is a bit slow due to the low RPM of the motor and takes about 6min. But that is kinda nice when fine adjusting to a frequency.

you have probably noticed that position vs resonant frequency relationship is rather nonlinear. you can get higher sweep speeds at lower end without losing much accuracy at higher end by tapering end of side plates into a triangle shape (it will get longer overall). it doesn’t matter much in your case, because it’s all approx monoband, but if you want to go multiband with this, then it’ll be a nice enhancement. similar effect happens when air variable capacitors have moving plates shaped in such a way that one end is longer than the other, and external edge has shape roughly like a section of logarithmic spiral. precise movement of variables like this is done by use of worm drive with large wheel

I am not sure what is causing this, but i assume it could be due to increase of dielectric losses in the capacitor getting bigger when more of the plates overlap because then the electric field has to flow thru a bigger area of dielectric, increasing the potential for losses.

loss tangent of dielectric is material property, that is ratio of equivalent loss resistance to capacitance should remain constant at given frequency. so i guess that losses should remain roughly the same, if dielectric is to blame, but at any rate lossy capacitor should make bandwidth broader and SWR lower. my guess would be that it’s a matter of coupling loop becoming wrong-sized or wrong-positioned at some point with change in frequency (try moving it up or down? there’s gotta be some optimum position for your entire range of interest)
