it's crazy how people memoryholed that (and japan doing the same, and a handful of other countries). or how until 2022 war norway wasn't really thought of as petrostate by people who didn't pay attention. or how ten years ago, if you said that putin bombed apartments to wage war on chechenya to win elections all to pardon yeltsin, people would think that you're a crackpot

i've collided with an article* https://harshanu.space/en/tech/ccc-vs-gcc/

you might be wondering why it doesn't highlight that it fails to compile linux kernel, or why it states that using pieces of gcc where vibecc fails is "fair", or why it neglects to say that failing linker means it's not useful in any way, or why just relying on "no errors" isn't enough when it's already known that vibecc will happily eat invalid c. it's explained by:

Disclaimer

Part of this work was assisted by AI. The Python scripts used to generate benchmark results and graphs were written with AI assistance. The benchmark design, test execution, analysis and writing were done by a human with AI helping where needed.

even with all this slant, by their own vibecoded benchmark, vibecc is still complete dogshit with sqlite compiled with it being slower up to 150000x times in some cases

yawn, i diagnose that LWer with weeb. this is something happening across entire industrialized world, causes being high performance mechanization of agriculture, old people being stubborn in regards to moving, lack of specialized work in countryside and couple of other factors. germany has patched their hospice staff shortage (not sure how effectively) with migrants, but japanese are way too racist for that. same thing happens in moldova, but you never hear sob stories about retired moldovans because they're broke and nobody cares, while moldovan govt can't really do much about it (because broke) to degree that it has not just economic and demographic, but even strategic effects. whole lotta drs strangelove in there

more like coopting dissent for profit, libertarian selling tshirts with guevara type of thing

 

I'm picking up an idea left by Dick KK4OBI, that you can lower impedance of dipole by arbitrary ratio if said dipole is zigzagged or otherwise uniformly contorted in some meandering shape. Side effect is that dipole becomes shorter and needs more wire. While there's data about impedance for fundamental, there's nothing about harmonics which is something that OCFD might be expected to handle well, so guessing that the really important part is aspect ratio of meander, i've made a couple of VHF-scale models with different meander aspect ratios (and many more much smaller sections), and some of data i've been able to collect roughly matches. The thing I'm trying to figure is what aspect ratio should be to cover multiple bands while using OCFD, say 40-20-15m bands, and whether impedances at different frequencies fall at the same rate. Eventually, when i figure this out, i'll try to make a full size 40m fundamental antenna, as I think that i've figured it out in mechanical terms

However during testing it turned out that I have severe common mode current problems, as two 10mm dia split ferrite beads were evidently not enough, so what little i've been able to collect is mostly useless. When I packed up everything I've found 4 Laird 28B beads that should together give 1100 ohms of impedance or so at 100MHz which also happens to be close to lowest frequency in my setup. Is this enough? Feedline is currently about as long as shorter arm of straight dipole at 22,5:77,5 split ratio, should I change it?

and i told you before that it's officers (pilots are generally officers) that will be doing aerial bombing, and because large force on ground is prerequisite for situations you're describing, it's not going to happen

this multicolored pattern looks like this because thickness of layer of whatever is comparable to light wavelength, mechanism is the same as in oil layers on water being colorful. it didn't spread from magnet, the layer is thinnest near magnet and becomes thicker near edges, which suggest it might be just dirt/oils that accumulated on it by contact. try wiping it with alcohol or acetone or what have you

according to his own claim, and he's selling his super secret methods. he might be just making shit up

i mean that saudis were somewhat restrained about airstrikes, at least publicly, but this action would cause them to not be so. even if they tried, there are extra air defences dragged to saudi for exactly this purpose; every cargo flight and every extra warship makes odds worse for iran, as more missiles would be intercepted, but even if nobody dies, shooting missiles would have diplomatic consequences. another action that would result in rising oil prices would be iran shooting ships in strait of hormuz, but this would also close access to their own single large oil terminal, and there are american warships nearby anyway, so it's perhaps unwise decision to make today

at this point, i think that decision to strike already has been made, and they're just stalling so that more metal can come from across the atlantic. dragging an aircraft carrier out there is not done for no reason, and the second one they want to put out there would need to have some of pre-deployment training shortened and done on the way, which is unusual and avoided because there were accidents that this training was supposed to mitigate
