Here's some uplifting news: the people of LA have voted and are aggressively backing safer streets. Change, even if slow, can happen.

"Under HLA, not only is the city obligated to install elements of its Mobility Plan, which can include bike lanes, bollards, daylighting, and wider sidewalks, but it must also track progress for the public online. It if [sic] fails to do so, residents can sue."

I've got an itch to activate a particularly difficult-to-activate POTA park. The few who found success did so with a barely-qualifying amount of digital or CW contacts with the exception of two prominent and skilled phone operators (and one of them had to give it a second try another day). What brings the difficulty is the terrain: the park is a ~~RF pit of despair~~ beach with 20m tall shear cliffs into the surrounding mountains. It's also remote enough to make spotting difficult; there's no cell nor a APRS repeater for self-spotting.

There are a few strategies I could go for, like beaming into the ocean for KH and VK stations, but I think this park is just about the perfect case for NVIS propagation. I'll probably give my EFHW a shot in an inverted V or sloper configuration, but I'm also thinking of building:

  • A basic dipole since I could pump more power into it than my existing EFHW transformer can handle.

  • A one-wavelength loop antenna. In theory a low loop offers a more circular radiation pattern than a dipole and slightly better gain. However, it's twice as much wire to raise.

What kind of portable antenna would you choose to operate daytime NVIS? Do you have any other ideas or thoughts?

G5TM put out a nice video where a viewer was debating between the inverted L and a compromised vertical. It's a good review between the two for folks with height limitations.

There are good parking garages and bad parking garages. What makes a good parking garage? I'd say good garages must be:

  • Located away from attractions and venues. The garage should not operate as a way to funnel cars into a popular area but rather as a way to store cars for those unfortunate enough to be unable to arrive by alternative means.
  • Located close to public transit. The garage should operate as a gateway into a local community, hence should have access to bike paths, trains and trams, buses, etc to carry their passengers into a community.
  • Be priced to cover the garage cost. Garages are expensive and the hourly/daily fees with average occupancy should pay for the garage in 10 to 15 years.
  • A tool to remove on-street parking and minimum parking requirements.

Bad garages are ones that break the good rules. They are:

  • Are free or too cheap to pay off their construction cost and land value in a reasonable time period.
  • Located inside downtown areas.
  • A method to increase the capacity of car storage in downtowns.

It's also possible for a good garage to become a bad one. Say a small town installs a parking lot on the edge of town, but then the town grows. That lot should be removed due to the increased land value it occupies. The new medium sized town can consider adding a parking lot or garage again, but certainly not in their popular, profitable, and active downtown.

Another deeply disturbing tale. RIP Ben.

I've had many coworkers roll into the office with their carbon bikes because it makes quick work of a long commute and it's so easy to carry a lightweight machine up the office stairs. They'd wear a backpack if they needed to carry a laptop. No cars involved; not even a bus.

There's no need to gatekeep which kind of bike someone chooses to use when the objective is to not drive a car. They can ride a carbon bike if they want too.

The advice is good (steel and aluminum are much underappreciated) yet this op-ed is weird and mean spirited. Yeah, carbon fiber bikes are expensive and quirky. They're a specialty bike for racers squeaking out tens of seconds to a minute or two of time. No one is seriously advising new riders to get a 10 grand bike. Why the gatekeeping? Let racers spend their money on their favorite, healthy, and engaging hobby.

There's a whole suite of vaccines which do not provide what you're asking for: sterilizing immunity. That's the penultimate ability of a vaccine. It's incredible we're even able to create anything of that character given we're fighting against living, evolving things.

Setting the minimum bar to "I must never get sick" instead of "won't find myself in a grave" or "I wasn't able to work for a month and was stuck in a hospital for three weeks" is a crazy thing to hang onto.

A friend of mine explained why it's important to his kids: they can't chat with a group of their friends.

Why? Because parents don't want to install WhatsApp or other group chats due to legitimate concerns about scammers, pedophiles, and other child predators. SMS chat fills that gap, but it breaks horribly for groups bigger than 10 people. Hence if some kid is on Android, they break their chat. Given the penetration of Apple devices, it's the kids with Android who are considered at-fault. "Just get an iPhone!"

Welcome to anticompetitive practices targeted at your children.

Spot on!

Sometimes even cheaters could be dealt with without an admin in those days. Servers would have fun game settings and odd maps that would break cheating gameplay.

My brother and I often played CS in the same room, on opposing teams because we didn't like being cheated and didn't want to be cheaters. We found an empty server with a sniping-only map. Made for great fun and someone joined in about 15 minutes later. They seemed really good, so we joined together to see if we could make it challenging. The new guy was just too good, so we decided to swap back and forth with the new guy to see if one of us could make a 1v2 miracle happen. That's when we figured out he was impossibly aim hacking. Bummer, our fun game was toasted.

Then we realized the map settings had friendly fire on and a 5 second start delay. Aim hacks don't target your own teammates. A perfect trap was available: we'd headshot TK the cheater at game start and then 1v1 each other. The cheater tried swapping to the other team only to find my brother using the same TK tactic. Our cheating friend found himself without a chance to grift. Needless to say, he didn't hang around for long.

Highways are a great way to install new regional transit. Brightline West is going to link Los Angeles to Las Vegas in the median of interstate 15. That highway is a total mess on weekends and this new line is expected to drastically reduce traffic with big convenience wins given its average speed of 101mph/165kph. And the project is funding wildlife overpasses and other habitat improvements.

As is typical, this science reporting isn't great. It's not only that AI can do it effectively, but that it can do it at scale. To quote the paper:

"Despite these models achieving near-expert human performance, they come at a fraction of the cost, requiring 100× less financial and 240× lower time investment than human labelers—making such privacy violations at scale possible for the first time."

They also demonstrate how interacting with an AI model can quickly extract more private info without looking like it is. A game of 20 questions, except you don't realize you're playing.

This is a regulated area, one that the SEC oversees. They've prosecuted insider trading on crypto: https://www.sec.gov/news/press-release/2023-98

Tech has been in aggressive growth mode since 2008 because the Fed was handing out free money (interest rate lower than inflation). That allowed investors to dump money into tech businesses in hope of rapid business expansion, which in turn makes the business more valuable.

The free money dried up. Now these tech businesses are going to find out if they're sustainable.

Q3 just ended. These layoffs are because the books are not looking good. Everyone is hurting with inflation and higher interest, tech being particularly vulnerable to high interest rates.

I can only hope the execs cut correctly. A second round of layoffs at a company can destroy morale enough to sink the company. Who wants to continue working at a place that fired your close peers, wondering if you're next?
