There is nothing more saddening than the state of America’s train situation. It’s like we’re fundamentally incapable of understanding the value of shared infrastructure.

In the rare case that a state escapes the matrix and actually realizes the benefit, we can’t get the damn thing built.

I want a packed bullet train, not a fucking slow private train car.

Strangely enough, Florida, of all places seems to be having really good success with their Brightline rail network. The initial system runs from Miami to Orlando, with a few stops in between. They're planning on expanding up north and east into the panhandle. Financially things are a bit dicey, but it got built, and it's reliable. Ridership is increasing, which takes cars of the road, and property values in the areas it stops are going up. Meanwhile California doesn't even have their tiny "initial operating segment" built, and is projecting to be up to 3-4x their original budget of 33 billion dollars.

I bought a new-to-me car that supports Comma.ai. It's not full self driving, but it handles the boring parts sitting on the freeway for me. it's the best purchase I've made in recent memory because holy shit sitting there on the freeway forever is the worst.

I got a used tesla a few years ago that came with FSD, and I fully agree. I drove to Vegas for DEFCON a few weeks ago and the ~8 hour drive was kind of just a mild inconvenience.

How do you feel after those drives of a few hours?

I have driven up to 6 hours at a time, but I'm in hyper-focus mode the whole time and it takes everything I have to stay locked into that focus so I don't die. I think all the time about moving somewhere where I don't need a car. I hate driving and always have.

I recently found out I have ADHD. I haven't tried meds yet (but am having my first meeting with someone tomorrow to explore it as an option). I'm wondering if this will make driving more tolerable for me. It wasn't even something I thought about before this thread.

Long drives for me used to be a fucking nightmare, especially long highway drives. Anything over 5 hours was basically an impossibility, now with medication it's really a mild inconvenience. I just moved to a new area, and I have a friend 2 hours away in another town. I don't even think about the drive when making plans, I'll happily drive up, hang out for a few hours, then drive back home. I still have limits on how long I want to drive (did 10-11 hour driving days when I was moving cross country, and that sucked), but they're way higher.

Having a car with lane centering cruise control also helps a ton, at least where I live. Not having to micro-manage a car for several hours when you're on a long drive reduces the cognitive load.

I can't drink whatsoever now. I've been on Wegovy for ~4 months. I used to be a VERY light drinker, i.e. like 10 drinks per YEAR (rum and diet coke, glass of wine, or 2-3 beers in a night). I would usually get a drink when my band played. A month or so ago, I got a bourbon, which I'll happily sip for an hour while talking, and I had to force it down, and left over half of it. Same with a beer; I went to a baseball game with some friends, someone bought the group some drinks, and it was disgusting.

It was like whatever enjoyment lightbulb that is usually activated was completely unscrewed, or like trying it for the first time as a kid when an adult lets you try a sip on a holiday. Just sitting here typing and thinking about it has me slightly nauseated. I've been telling people recently I CAN'T drink because of some new medicine I've started.

When I took Adderall in college a few times I had a very similar feeling. You could have told me my favorite restaurant was giving away my favorite food, and it would have been nauseating while I was on the meds.

barnas2 commented on Impacts of adding PV solar system to internal combustion engine vehicles jstor.org/stable/26169128... · Posted by u/red369

pchew · a month ago

I have a 100w solar panel on top of my car...to tend a 12v battery. It's got a Dewalt battery charger, mikrotik ltap, and raspberry pi hooked up to it. Little hotspot with multiple sims and resource server(mainly just for fun). Anyone that can do basic math should immediately realize there's just not enough area to make an appreciable difference in regards to mileage.

barnas2 · a month ago

The Prius Prime solar panel roof I think can net 3-6 miles a day under ideal conditions (which we're probably close to here in Arizona). I think that's a little more than people would expect, but still only applicable in niche conditions (tiny daily commute, or a longer non-daily commute). I think the math works out to ~4-6 years to break even for the cost of adding the solar roof assuming $0.15 per kwh, which isn't terrible.

If solar tech gets more efficient or cheaper, I think it starts becoming a much more attractive option in some areas. If you get into the 10+ miles per day range, that would cover a lot of peoples commutes in certain areas.

I always want to reach for `units`, but I'm perennially baffled by the output! What's up with the * and /?

barnas2 · 2 months ago

the * is denoting the conversion from your first unit to your second, the / denotes the other way.

You have: 1 miles You want: feet * 5280 / 0.00018939394

In the above example, 1 mile is 5280 feet, and 1 foot is 0.00018939394 miles

If I do 2 miles to feet, the values are doubled (or halved for the reverse conversion)

You have: 2 miles You want: feet * 10560 / 9.469697e-05

I guess you don’t want the fastest speed or no data cap. We easily surpass the 1TB cap with 4K streaming and WFH video calls.

barnas2 · 2 months ago

I use Cox and get their fastest speed (2.5Gbps) with the option for unlimited data if I wanted it, and I'm using my own equipment.

You can’t get top speed or unlimited data with your own modem.

barnas2 · 2 months ago

Not sure about Comcast, but I have no issues with Cox. I'm getting 2.5Gbps with my own equipment (Ubiquiti UCI, which is $$$, but other cheaper modems also work).

Is anyone able to test it via AiStudio? I pay for Google's AI subscription, but any attempt to use this model results in a message telling me I've hit my rate limit.

What does this thing do? The sales page doesn't help much either "The comma 3X is custom hardware designed to live in your car, and purpose built to run openpilot." What is openpilot??

To me this just looks like a generic dashcam

barnas2 · 3 months ago

It's really not hard to just search "openpilot" and click the first link. There's also a link at the top of the comma.ai website that links to the same page.
