  • I upgraded my license when my grandfather had to move in with my parents so I coul help him setup a smaller shack and assist in operating the radio with him. He deeply appreciated the family time, and I’m sure your Uncle wouldn’t mind spending time with you too.

    For whatever it’s worth, these web interfaces are great at listening and cost nothing. Ask him to help you operate (finding signals and how to listen to them) using a KiwiSDR online. If you find out he’s also having fun, then perhaps look into remote radio station equipment. There’s a wide selection of transmitting capable SDRs, like FlexRadio, and DIY solutions (e.g. https://www.remotetx.net/). You can even rent remote operation time with incredibly nice hardware in amazing locations (e.g. https://www.remotehamradio.com/). Perhaps he’ll be come interested in another side of ham radio that he hasn’t done before either, like working satellite passes. That doesn’t take more than one nice, or two very cheap, handheld radios and a small handheld yagi.


  • Ham radio can be used as voice chat with friends, but that would be a pretty limited view of it. Here’s some things that a Discord Voice Chat cannot do that radio can:

    • Chat without internet (e.g. places without cell towers).
    • Chat without voice. (digital communications of all kinds; email/text, keyboard-to-keyboard, pictures, etc).
    • To build an internet (e.g. building WiFi meshes with extra power [AREDN], AX.25 packet, WinLink).
    • Used as a tool during emergencies (see ARES/RACES/CERT).
    • Chat completely randomly (it’s just one big discord channel, but you can only hear some people).
    • Chasing the challenge of unusual radio propagation (earth-moon-earth, meteor bounce, tropospheric ducting, aurora).
    • Chasing the challenge of collecting the most point-to-point contacts (contests).
    • Chasing the challenge of difficult radio propagation (microwave links).
    • Constructing and using radios that you cannot buy off the shelf parts with (usually with those funny microwave guys).
    • Higher power versions of things unlicensed folks cannot do (RC toys, Meshtastic/LoraWAN, WiFi, etc).
    • Historical preservation (restoring old radios, keeping ship-shore coastal stations running [e.g. Maritime Radio Historical Society]).
    • Conducting scientific experiments (HamSCI, and I conducted one listening to the ionosphere during the recent total eclipse).
    • Building and controlling satellites (AMSAT).

    And there’s even more. The way to view ham radio is the government grants you a license to operate on many pieces of radio spectrum so long as you can show your technical ability to not cause harm (interference, safety, and things that will prevent you from blowing up your radio as well as find success in using it). What you do with that spectrum is up to you!


  • Since you brought it up, let’s dive into the numbers as presented[1]. The top all-cause is heat disease. A disease that’s preventable by moderate exercise (e.g. walking, biking, playing baseball, anything really) and avoiding common legal drugs (tobacco and alcohol being most implicated, but also most available).

    Next up, cancer. Also a general class of disease that has many causes, but has also been shown that moderate exercise reduces cancer risk.

    COVID and respiratory disease? Preventive measures like vaccines and, again, moderate exercise also reduce this risk. Oh, and cars are a factor in this category (long-term inhaling tailpipe emissions will make your lungs unhealthy).

    Opioid overdose (1:55)? Suicide (1:87)? That’s somewhat self explanatory to fix, but good medical care and moderate exercise again helps.

    Guns? That’s all cases of guns. Homicide (1:219) and suicide (1:159) by guns must be rolled up to get to the 1:89 figure. Homicide is a big issue to untangle, like suicide. That said, homicide has been linked to car infrastructure depressing local economies and as a tool in segregating black communities into unfit areas away from economically viable white ones.

    Then we’re finally down to falls (1:92) and cars (1:93).

    What can we take away from this? If you’re trying to reduce risk, go for a walk or ride a bike regularly. It’ll help you avoid heart disease, improve odds against respiratory diseases, and is a good tool for upping your mental health game. No need to trust me. I’m a dog with a keyboard. Talk to your doctor about it. You may be surprised how effective reducing drinking, stopping smoking, and going out for a walk every day can do.

    Whoops, my bad. Pedestrian “incidents” (ran over by car) is the next cause (1:468). Cycling isn’t too far behind (1:3,162). Maybe we should continue to drive overhead bad parts of town, inhale our neighbor’s car fumes, and enjoy our near-guaranteed death by heart attack and choking.

    [1] In the OP’s data source. It’s a good source, but it is US biased and biased in NHTSA’s reporting (e.g. person in hospital from a car, but died >30 days later? That’s natural causes.).




  • Not every member of the fuck cars community is about car infrastructure, even though I personally fall into the infrastructure camp.

    Say you have the viewpoint that guns should be tightly controlled due to the number of people killed by them. Cars kill approximately the same number of people in the US every year (depending on if you count suicides and if intent is important). If guns are bad for deadly external behaviors, then so are cars. Just like how there are gun ranges or race tracks for responsible ownership, there can be gun related murder and car related murder. Ban guns and ban cars.

    Case in point is this very article. It appears to be a hate related crime committed with a car. Germany tightly controls gun ownership, so why would we dismiss tight control of car ownership? Should we allow this person to drive again if he’s convicted? Why do we allow DUI drivers, who have killed others before, to continue to drive again? What do devices like ignition interlocks say about us?




  • If a cyclist can ride right through this, why can’t I on my 125 motorcycle?

    Perhaps it should be allowed! Cars already treat stop signs as yields (“California Roll” is the car corollary to the “Idaho Stop”). Why would you stop if the car behind you isn’t planning to? (I’d love to see motorbike studies on this; please link me to some if you know any.)

    Studies have shown that cyclists treating stop signs as yield signs leads to fewer accidents, both with cars and pedestrians.

    Yielding also decreases time spent in the intersection. You have a motor underneath you. Cyclists don’t. Clearing the intersection quickly prevents cross-traffic from splatting you. That’s why slowing down, checking for traffic, but not stopping is so important for momentum vehicles.

    The NHTSA (the US road safety org for my Canadian friends) has a good two-pager overview. It’s a good place to start if you’re still curious about the reasoning behind the Idaho stop.




  • I’ve been using a Topeak Joeblow for more than 10 years now. I don’t exactly remember when I bought it, but I’ve thrown it around quite hard and it still works great today.

    That said, it’s not possible to have a forever-pump because all pumps have seals. These seals will slowly degrade over time. What you should look for is a company that sells spare parts and rebuild kits. Ideally a company that has been around for a long time so you can have a decent expectation that they’ll still be around when you need a rebuild kit (new-old-stock doesn’t work great for rubber/leather goods). Bonus points if the rebuild kit looks like parts that you could make or find from a local hardware store; just in case the company does fold.

    Studies have shown that blinking lights improve reaction time to bikes on the road. The most common issue is determining the distance to the bike. This effect is more pronounced during night.

    That’s why I use my bike lights all the time set to blink with a multi-second on phase. It makes me more noticeable and easy to estimate distance.

    Also cars do have blinking lights these days. The newer car models like to blink the center brake light for a second before going static. Motorbikes have also long had rear blinking and “breathing” front light.


  • The honking thing specifically is another skewed fact. The neighbors want the Waymos, they just had a hard time getting ahold of the right folks at Waymo. That includes Sophia Tung, the neighbor who set up the honking video stream that Jason used.

    As a local in the area, I can say for certain that the majority of SF wants the cars there. There’s more resistance further down the peninsula, but it’s intermixed with anti-taxi messaging. It’s hard to tell if it’s about the cars or about “those kind of people” having access to their city.

    San Francisco neighbors say repeated Waymo honking is keeping them up at night

    Christopher Cherry who lives in the building next door said he was “really excited” to have Waymo in the neighborhood, thinking it would bring more security and quiet to the area.

    The residents who spoke with NBC Bay Area said they are not opposed to having the Waymo cars nearby. But they say they want to see a more neighborly response from the new autonomous vehicle company on the block.

    “We love having them there, we just would like for them to stop honking their horn at four in the morning repeatedly,” Cherry said.

    San Francisco neighbors say Waymo honking continues, global audience follows along live

    The incidents were captured on resident Sophia Tung’s YouTube live stream

    Tung and many of her neighbors said that they are Waymo customers and actually like the Waymo technology. But what they don’t like is the repeated, overnight noise.


  • Well, formerly operating companies. The Uber and Cruise examples stopped both of them dead. Uber left the business entirely and Cruise had its license to operate revoked.

    That’s just omitting info. There’s also straight up wrong stuff, like residents not wanting it. As crazy as it sounds, at least with SF, the residents’ reps wrote the regulation law and haven’t had a measure to reject self-driving cars (at least K passed). The majority want to see these cars. Also, Facebook dumped their move fast motto a decade ago because of how bad it was (self-harm problems).

    It’s unfortunate too. I like Jason’s rants, but it’s too distracting when he gets a quick google level of facts wrong.





  • San Francisco’s critical mass was successful to the point it almost doesn’t exist anymore (it’s not necessary anymore with better political engagement). I believe it was successful because it:

    • started at the same location and time (once a month on a Friday)
    • occurred during evening commute hours
    • had no formal leadership
    • no planned route until just before departure

    This combination meant authorities had no ability to shut it down. What office could the raid? How could they bring a lawsuit?

    Once a month on a Friday meant it didn’t have to be about your commute. Rather you’d leave work and ride to the start point. It was a protest first and a utility second (though the route did start from the financial center of the city).

    Take a look at bike parties if you’re looking more for a community ride. They bring more of a general supportive base than as a protest.
