you'll be lucky until you aint, then you'll get banned for ban evasion

that destination could be still somewhere with access to stranded fuel and with access to other port, like oman, or they could perhaps truck it to yanbu and ship from there, but it doesn't matter because price increase would probably need to be even bigger for it to make sense. facility would also need to run only on fraction of capacity, and there's probably no point in that if you can't export everything that's made there. currently it might be damaged anyway. what i mean is, there are problems solvable by throwing money at them, but it's probably not one of these

well it would be if refineries nearby would be running, but they don't, because there's no good logistics chain in place

all that jet fuel is right there

for context, this is something that will matter especially for higher-end boards, specifically boards that handle higher frequency signals than usual, think 5G connectivity things, or where engineering margins are thin. if there's a will, they could fly that plastic pellets out of saudi, or set up other logistics routes, as long as cost increase over just using container ship would be justified. it'll be only a fraction of mass of laminate in any case

but that would cut down openai costs

for now? they are floating on vc money, but their losses are so monstrously huge that they spent good chunk of all of it available worldwide. the way they got it was by promising replacement of work by their bots, aided by captive press and six billion marketing budget from openai alone. but they don't have plan to get profitable, and when money influx stops they're cooked like nobody before has been

tbf i expected that ed got openai's s1 at that point. anything more detailed would be nice to see. that also suggests that saltman knows that leak occurred, and maybe who leaker is

i'll just quote it straight because i can't make it any funnier:

maia arson crimew 🏴 ‪> @crimew.gay‬ SCOOP: So remember Dialog, Peter Thiel's private society that doesn't have a public website and no public list of members? I (along with a number of other journalists) have just been tipped off that embedded in the code of their closed off website there IS what seems to be a list of some members.

zitron got a scoop on openai: 8.8B loss in 2024, 60.3B loss in 2025, 1.17B from ms + softbank, promises more detailed analysis later https://www.wheresyoured.at/exclusive-openai-financials/

there's a couple of jobs where you get to do both!

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?
