"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.

Hams make a game of it: https://www.arrl.org/files/file/WA50-Standings/Distance-Reco...

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

>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…

I just went down a rabbit hole researching a toothpaste that's giving me constant ads. I went looking for reviews and ended up posting a comment on /r/PeriodontalDisease - https://old.reddit.com/r/PeriodontalDisease/comments/1bcna04...

TL;DR: EDTA is the magic ingredient that will annihilate the disease-causing biofilm on your teeth & gums, especially when you fund your own studies and spend the rest of your money made from your overpriced toothpaste gel on marketing.

Just brush and floss 2x a day, and chew gum if you like to.

I don't know how it couldn't be more obvious the only option they had in order to satiate Wall Street is to buy more GPUs for their wildly overbooked AWS demand induced by AI, and the only way to do that was by cutting fixed costs, aka salaries.

Paper is open source.

you can make one out of cardboard and aluminum foil (better yet, aluminized mylar (space blanket) on foam) on the order of a few oz. https://www.instructables.com/Lightweight-Radar-Reflector/

A radar reflector such as that, or this (https://overlookhorizon.com/product/radar-reflector/, which is ~300g) has roughly the same RCS as a small (piper cherokee) to medium (gulfstream) sized aircraft.

That being said, detection isn't everything; primary radar cannot make accurate altitude measurements, only bearing and range. While that's enough to route traffic around, it could be also mistaken for a false return.

Some do. Edge of Space Sciences (EOSS) is group of citizen high altitude scientists, and their large balloon flights include certified ADS-B transponders [0] and radar corner reflectors. They also file their flights with the FAA to publish NOTAMS. They have significantly larger payloads than this, but are designed to quickly ascend to ~100kft and pop reducing the loiter time in congested airspace.

Project Loon balloons also show up on Flightaware, so they either have ADS-B or TIS-B.

A situation like this will almost certainly cause some congresspeople to fret and write bills that would require ADS-B on all balloons, which would be a death knell for amateur ballooning unless ADS-B (or "legacy" Mode A/C/S) transponders become significantly smaller and more affordable. Mode C/S transponders are already available in miniaturized form factors thanks to the UAS industry, and are designed to be interrogated by aircraft equipped with TCAS (i.e. all 10+ passenger aircraft) that provides pilots deconfliction commands automatically and with no ATC support. But they're still priced for industry, not amateurs.

There's a cool million in some landfill in rural MO, because I did exactly that.

It's funny to imagine how much the one "random act of pizza" I contributed multiple BTC that I mined on my Dell Dimension Pentium machine (worth multiple pennies USD then) is worth now.

ABC/Disney made the choice to pull Kimmel, bent at the knee in fear of losing their broadcast license. That decision itself is one worth questioning...what if they didn't? Would the FCC actually do it? If they did, how many lawsuits would come their way since that's the greatest infringement of the First Amendment the US has ever witnessed? Wouldn't ABC, the public, and the First Amendment win out massively at the end?

What if that bit of libertarian anarchy played out?

ABC ignores the backlash and threats, and keeps Kimmel on the air, maybe even encouraging speech against those bullies and hatred. Then FCC pulls their license, but ABC keeps broadcasting. Their pirate broadcasts would escalate both sides even further: stoking a great groundswell of support for the freedom of speech from liberals/the left, a storm of legal battles representing We The People v. the Government would form, and a massive (possibly violent) outcry from far-right conservatives and nationalists. What happens then would redefine our nation. Would corporations back ABC and capitalism retake the reins, and grassroots efforts steer the misguided Right back to normalcy? Or would an explosive sabotage and a bloody battle over the fate of our nation take place before any progress, or regression, would happen?

As much of a work of fiction as that sounds, it's almost more believable given the timeline we're already on.

every dynasty and empire after the last was the “smartest” compared to the one before, yet they all still collapsed.

The "your brain on ChatGPT" is giving the same feel as DARE's "your brain on drugs" campagign, and we now see how that went. It immediately loses any credibility for me.

It wasn't immediately clear what they actually had the subjects do. It seems like they wrote an essay, which...duh? I would bet brain activity would be similar -- if not identical -- as an LLM user if the subjects were asked to have the other cohorts to write their essay.

I have this book, and it's been on my nightstand for about 3 years, still haven't read it.

I notice this too.

I've made a new year resolution in 2024 to be much more outgoing with my friends and coworkers, and to go to more concerts. My wife isn't a concert person, and I don't have many local friends. But still, I always buy two tickets and, to the friends and colleagues I will offer the other ticket, usually in conversation or at random, usually months in advance, and usually at no cost just because I just really like having friends -- who doesn't?

Of the 6 shows since then, 4 people accepted to go with me, but all of them ended up cancelling. One friend tapped in at the last second just because he was a local student with nothing better to do on friday night. So I've been to a lot of concerts alone, which kinda sucks. Everyone else is there with some companion, but I'm kinda extraverted so made a few acquaintances.

I also planned a fishing trip with another -- free airfare (companion pass) and lodging (family condo) for them -- and cancelled about 2 weeks prior to it.

I also realized i'm the manufacturer of my friendships -- I am the one who asks friends out for lunch, brunch, hikes, beers, coffee, picnics, game night, etc. I'm the conversation starter. I send the plurality of reels. I'm reminded of my friends on a daily basis from random happenings, that spur me to get a gift, or send a news article, or just a pic or text, or to form a plan for a birthday party or fishing trip or cross-country flight or anything.

They'd often accept the small stuff, and things were good. But I backed away during my recent paternity leave, and they basically disappeared. I still send and receive some how are you's, but it made me realize how lopsided my relationships became.

I kinda burnt out manufacturing my relationships (also after learning about that term), so I stopped, and for the last 3 months I've been essentially devoid of friendship (except for one person who ).

Started to make me think I smell or something, but reading of the male loneliness epidemic and an overall dissolution of community is making me realize the only thing I'm doing wrong is not continuing to manufacture my friendships like I was before.

I'm hopeful but pessimistic about Slate. There is still time for them to A.) raise prices because of "unforeseen" issues, B.) enshittify with tech or wacky pricing structures.

CTRL+D it's that easy.

I spammed the columns from 1 to 402 (with 400 rows), and i saw some cool patterns. I can see a few nodes of clockwise rotation that converges into a single node from >200 columns that starts makes its way down the screen. Trippy.

I made a screen recording of it: https://n0ssc.com/wp-content/uploads/2025/08/prime-doublespe...

idk, hardware engineering (whether electrical, mechanical, civil, aerospace, etc) is just as lucrative and IMO more interesting, since physics isn't an invention of the human mind like software is, and mistakes go boom instead of segfault.
