I think that, a little over four years after leaving the country, I finally have no bank accounts or any other ties in Hong Kong.
(They just abruptly cut off my ability to log in, but it was following a conversation about closing my account, so I assume that's what they've done. A more explicit confirmation would have been preferred, but oh well.)
I take this as a vindication of "no matter how late, still better than never" :)

Misophonia has become a serious problem in my life. There's a person, who is totally great, and who is friends with all my friends and gets invited to everything I'm invited to, that I cannot be around for long periods because when they laugh my brain instantly jumps to an emotion not too far from blind rage.
I don't know what to do about this; it's very intense and basically preventing me from doing most social activities, even things in my own house.

Sorry to hear it, this sounds very inconvenient and also socially very difficult to approach
My misophonia feelings have varied over the years FWIW. Certain mouth sounds bothered me a few years ago, then they didn't stand out again til a few weeks ago. But my thing has always been much milder than the thing you're describing.
Have you tried loop earplugs? I think they say they can help with misophonia, and my friend with more widespread misophonia said they help a bit. Idk if they'd help with someone's laugh though.

I spent the whole weekend building this... Err... "Portable" directional 2m #hamradio antenna with @Jen Blight, and it was pretty great.
(It's portable in the sense that it only weighs about 2lbs, and can be taken apart to fit in a backpack. I hope to make substantially more portable ones in the future).
The elements are made from 0.5" PEX irrigation tubing (think hula hoop material), wrapped in copper-coated fabric and copper tape, with a layer of clear "repair" tape to prevent tarnishing, while preserving the mad wizard staff vibes.
Each tube is connected to itself using Anderson powerpole connectors, so they can be easily unplugged, and twisted into a smaller footprint for travel.
The boom is a fiberglass driveway marker, and the mast is a telescoping fiberglass pole.
I don't yet know how well the antenna performs, and as you might be able to see from the VNA, it needs a little tuning. But my radio didn't emit any smoke when I transmitted using it! And the signal made it clearly to its intended target (who was about 30ft away).

Update: I definitely see a fair chunk of gain! Not enough to communicate with Jen all the way in SF from my back yard, but my field strength meter shows ~40 units when my standard whip antenna only gets ~10. I'm not sure how to interpret this, but if it's roughly proportional to power, I think this implies roughly 6dBd / 8dBi? Also as far as I can tell the front/back ratio is excellent; saw barely any movement in the meter when placed behind the antenna.
I'm pleased with this as a first attempt!

I'm currently using my 64-core Linux desktop to run a genetic algorithm to optimize my design for an emergency #hamradio antenna. About an hour ago I submitted a patch to the (Haskell) codebase of the optimizer to allow it to support curved wires, which I needed because my design is made of four circular hoops. Despite being a fairly low activity project, the PR was merged within about 10 minutes, which felt awesome.
Am I cool yet? How many more layers of nerd do I have to add before I'm cool?

While researching, I've seen a few similar designs with several different names; "circular quad beam", "cylindrical quad", "E-Z-O" etc.
I'm very new at this so I don't have as much equipment as I'd like for testing this stuff. Just ordered a cheap field strength meter, so hopefully will be able to do better than the "can you hear me now?" test.
Seriously interesting project. I've used the optimiser in 4NEC2 but it only has preset things you can choose to optimise. Being able to use a Python script as an objective function would be so much nicer 🙂
Anyway looking forward to hearing about what you end up with ...

I for some reason feel quite emotionally attached to whether I'm allowed to walk into roads or not, and am glad to see that freedom (which the UK has always had) spread a bit more in the US

Trying a couple different materials for my "emergency kit highly directional #hamradio antenna":
- Stainless steel spring-crafting wire (idea credit: @flammifer@superstimul.us) isn't the best choice of antenna material or diameter, but it is extremely portable: I'd add connectors so I could unplug the ends and twist the wire up, to have it fit in about one square foot.
- PEX tubing is much lighter than it looks, is much sturdier and harder to accidentally deform, and covering it in copper foil tape should produce an excellent antenna. But it would be much harder to fold a PEX antenna down into an emergency kit sized package.
I think I'm just going to make both and compare them.
