"Ideal" isn't doing as much heavy lifting as I thought it would be in this article. This is a basic wardriving setup on flat ground.
Standard wifi is phy limited to ~1600m unless you can increase ack response time limit, otherwise retransmissions will be sent by the sender while ack's are being transmitted by the receiver.
Then, per friis equation, with enough power and antenna gain (it's the antenna gain that really matters) the limit is only obstructions/terrain. Get yourself high enough (mountains, planes, satellites, moons, etc), or bounce of an opportune reflector (planes, moon, aurora, meteors, ionosphere, rain, hail, etc), and there is no real limit, besides how big of an antenna you're willing to build in orbit :P
or just make the throughput really really really REALLY slow and ice your receivers with liquid He.

is anyone using keybase any more? i put it on my website and socials to do just that but it doesn’t seem to have stuck around.

Likewise. Every query returns dozens and dozens of AI generated domains and blog posts like this. It’s MUCH better than google with filters and small web but still sad.

The ham radio microwave community thanks you.

I'm in the big city. I've experimented with using my running/position lights only on slower, congested streets at night when the street is well illuminated. I know I have a car with annoyingly bright LED headlights, so it feels like I'm being courteous. The LED position lights are surprisingly bright too, but at least it' s diffuse. When the street is less illuminated or traffic is more sparse my regular headlights go on.
This does not influence the behavior of oncoming traffic with high-beams on, whether due to ignorance, entitlement, or because their low-beams are burnt out and they can't be bothered, or afford to replace them.
It's also not legal to do what I do, so it's ironic that I'm probably at higher risk for ticketing for not driving with headlights than people with high-beams or broken lights (to be fair not a lot of people get ticketed for basic violations in STL city).
I do wish I could have them angled down on demand, or follow a set level point regardless of vehicle tilt (like on hills, speedbumps, etc). They do have a feature where the lights steer into the direction of travel, if only they did that vertically too.

Sometimes the opposite is true.
My century-old fortune 50 workplace does not have free. Autodrip coffeemakers are provided, but the coffee isn’t free. Employees bring it in with a jar to collect “coffee club membership fees.”

My blogpost titled “Millennials are killing ham radio” has received the most hits out of all of my other posts. It got me an interview with IEEE Spectrum and basically cemented my name as a ham radio influencer.
Amateur radio is a remarkably niche hobby so that kind of attention is rare, but it took ragebait to do it. A title like “The Next Generation of Ham Radio” would have flopped. I know this because that’s what I titled it first, and after 40 views in 2 months I slightly rewrote it and reposted it under the new title and within a day it appeared on just about every ham radio forum, facebook group, numerous email reflectors, and so on.

Before reading the article, I guessed the headline was alluding to the popularity of Hypochlorus Acid as a sanitizer, made from electrolysis of slightly acidic salty (NaCl) water. I had a kid and the algorithm led me to discovering a brand of in-home electrolysis generators, and after a fair bit of research on safety and efficacy I’ve been using it quite a bit.
Technically it solves contamination problems too.

That makes a lot of sense… I’m in the rich/middle class north Atlanta burbs visiting family, and the entrance to every cul-de-sac has a flock LPR pointing inwards.
I didn’t notice it at all last year but the cameras were there. Benn blew the cap off and now they’re omnipresent.

>he doesn't seem to realize intent is a thing
at 2m9s [0],
>theoretically, that type of pattern could randomly show up if you were just driving through mud. Is it the intent that makes it illegal? Is it the presence of it that makes it illegal? If you have a certain amount of mud on your license plate and that cop doesn't likeyou, could he use this law and be a dick and put you in jail the same way that he would if you were driving with an open bottle of Absolut and swerving in and out of your lane?
Not only does he acknowledge intent is a thing, I think this is more a commentary on the ambiguity of the bill, which states:
>A person may not alter the original appearance of a vehicle registration certificate, license plate, temporary license plate, mobile home sticker, or validation sticker issued for and assigned to a motor vehicle or mobile home, whether by mutilation, alteration, defacement, or change of color or in any other manner.
The lack of the word "knowingly" makes it ambiguous whether intent matters. A person who drives with a plate covered in mud, bugs, or bird shit could be theoretically be charged by this law not because of intent to obscure it, but because of the person neglected their duty to keep the plate clear of obstructions so it could be read by these LPR cameras that infringe his Fourth Amendment right.
I'm sure theres a lot of other legal context and case law but laws shouldn't be written with loopholes or ambiguity like that in the first place.

It’s the perfect pharmaceutical miracle drug: a shot that cures the root cause for thousands of diseases (obesity) with a whole bunch of unexpected benefits (like reductions in substance abuse, fewer migraines), with mild symptoms and rare complications. But you’re stuck on it for life or else return to your pre GLP1 body.
The fact it spun of of research on Gila monsters is still crazy to me.

Maxwell's equations have yet to be disproven but this comment implies otherwise.

I love this a lot. Bookmarked, watched, and starred, looking forward to updates. Namely, click-on or mouse-over labels for each channel (thinking of a grafana dashboard). I turned everything on and got lost in the spectrum lol.

I’m more confused why would he start a school in the first place…
