what a way to learn that she was already released

You might be better off exchanging them before travel, you would need to look up rates

dropped as cleanup-only, not allowed by their policies

i suspect that it might be vibecoded, too

it also happened with tramadol before (different plant)

- hey chaotic systems are a thing, you can't predict every single last detail

gwern: as a proof that you're wrong, what if we placed everywhere very fast robots that avoid getting into chaotic systems in the first place

perhaps, but only americans bitch about it so loud that you can hear it across the ocean

spare a thought and a prayer for all these careers of ambitious propagandists and engagement farmers, dislocated without warning

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

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'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?
