that's way more power than needed to feed 800W out 24/7, what happens with the rest?

figuring out other people's mistakes when trying to replicate their results, closely followed by figuring out my mistakes when trying to replicate my own old results

fresh hellish nonsense brought to you by ai-gen podcasts enabled by techbros interpretation of consent and privacy:

https://www.404media.co/this-company-is-secretly-turning-your-zoom-calls-into-ai-podcasts/

WebinarTV, a company that bills itself as “a search engine for the best webinars,” is secretly scanning the internet for Zoom meeting links, recording the calls, and turning them into AI-generated podcasts for profit. In some cases, people only found out that their Zoom calls were recorded once WebinarTV reached out to them directly to say their call was turned into a podcast in an attempt to promote WebinarTV’s services.

“WebinarTV is believed to leverage a range of browser extensions that provide functionalities such as AI powered transcription and note-taking tools, or tools to automate the joining of online meetings. The platform mostly relies on the widespread use of these tools by end users, rather than operating them directly. However, at least one of the known extensions is listed on the Chrome Web Store as developed by WebinarTV.”

i see elsewhere that wikipedia after all restricted a bit more use of chatbots, and i'm very interested how much kicking and screaming did it involve

Adding to that, logistics are such that direct impact will be felt strongest in places like India that rely heavily on Qatari LNG to make fertilizer, but many places have other sources of both gas and fertilizer. Americas, EU, Russia and China will get by because they have their own supply and will be only affected by price increase

without synthetic nitrogen fertilizer there's only enough reactive nitrogen going around for something like 1-1.5B people. yea mate very sustainable to retvrn to traditional farming and starve 80% of the planet in the process

good, dare i say, based even. you better start figuring out where to put these panels, because roofs and parking lots won't be enough (maybe taking into account soil type and how it is already used)

some people think that solar panels suck out solar energy from around like some kind of evil wizard depleting lifeforce and never heard about shadows

Remind these racist idiots that Chinese went all on solar and aren't affected as much by oil supply problems, and you wouldn't like to be worse than them, right,

maybe it's carbon monoxide detector going off, it would make more sense

immersion destroyed immediately (they never face consequences)

this also puts altman in position to forge identities at will

 

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?
