I've also asked the youtube ai about when some things are mentioned in videos, and upon verification the ai is just hallucinating.

jonwachob91··on Loss of key US satellite data could send hurricane forecasting back 'decades'
I'm from Florida - born and raised. I've never once heard anyone call any hurricane "the end of Florida as we know it". What I have heard, and seen, is extreme damages caused to homes and cars even hundreds of miles away from the eye of the storm.

In 2022, Hurricane Ian caused extreme flooding in the Orlando-region, including in areas that have never suffered from hurricane flooding before. For me personally, all 3 cars parked at my house were total losses b/c of the flood damage.

The extreme and extensive damages in the Appalachian region last fall is another great example of hurricane risk not being "grossly exaggerated".

jonwachob91··on Loss of key US satellite data could send hurricane forecasting back 'decades'
That's not at all how insurance companies price risk. Unknown risk is more risk, and more risk is more expensive. Therefore, unknown hurricane data is more risky and thus more expensive.

If you know your car's engine is going to need replaced after exactly 100,000 miles, you know to save up for a new engine or a new car - and you know how long you have to save, so you can precisely set aside an appropriate figure every month.

If you know your car's engine will die sometime within the next 15,000 miles, you know you need to start saving up immediately, but b/c you don't know when in the next 15,000 miles you have to rush your saving.

If you have no idea when your car's engine is going to die, you are likely to end up dead engine and little to no savings.

jonwachob91··on Tesla Solar Sales Declined for 4 Qtrs. Then Tesla Stopped Publishing the Numbers
If you are willing to put in some Project Management time yourself, you can get solar for a LOT cheaper than if you hire an outside solar company.

For the installation - most roofing companies will install the roof mounts and screw on the solar panels for $1.5k-$2k (might be different in your area, but still cheap). An electrician can be hired to make all the solar panel connections and the grid connection for a few hundred $$$.

As the Project Manager - you'll need to source the panels, file the permits, and hire the roofers and electricians. https://www.solarwholesale.com/jerry-rig-everything/ can assist (assist, not do) all of that for you for a cheap price. $10k-$15k with Solar Wholesale will get you the panels and cables you need, plus the engineering drawings, the permit paperwork, and etc. (thank you for the great Solar DIY series Jerry!)

For $20k and working as the Project Manager yourself, you can get what most solar companies will charge you $50k for. Which is ballpark inline with construction project management costs - typical residential construction project management cost 40-50% of the total project budget. A lot of those projects as complex enough to warrant those fees, unless you have a lot of experience, but in my opinion adding solar to your roof is not a complex process and does not warrant those fees.

jonwachob91··on U.S. homelessness jumps to record high amid affordable housing shortage
Did you not read the part of my comment were I clarified "cities without major homeless shelter capabilities"? New York has major cities that have the infrastructure and resources to shelter homeless populations during major cold events. Plenty of Northern CITIES have those capabilities, but WV doesn't. WV doesn't have a single major city and doesn't have the capabilities to shelter a homeless population during major cold events.
jonwachob91··on U.S. homelessness jumps to record high amid affordable housing shortage
>> COLD towns without major homeless shelter capabilities

"without major homeless shelter capabilities" is a key part of my original claim. Every city you listed is a major city that has the infrastructure and resources to shelter homeless populations during major cold events. Plenty of Northern CITIES have those capabilities. but WV doesn't have any major cities and lacks cities with the capabilities to shelter homeless individuals during major cold events.

jonwachob91··on U.S. homelessness jumps to record high amid affordable housing shortage
>> Places like West Virginia have way less homelessness than places with high housing costs like the west coast.

COLD towns without major homeless shelter capabilities always have lower rates of homelessness b/c the cold weather is literally life threatening.

Warm(er) regions, like most of the West Coast that isn't known for blizzards, have higher rates of homelessness b/c there is little risk of death if a homeless person camps out in the woods. Note that a lot of homeless folks in warmer regions didn't become homeless in those warm regions - they often become homeless in northern regions and migrate to warm regions prior to winter.

Comparing homelessness in WV to Cali doesn't seem fair since so much of the folks that become homeless in WV are forced to leave the state to survive.

jonwachob91··on DOJ accuses Visa of monopoly that affects price of 'nearly everything’
>>> Credit card fees are where the real money is made, and the meat of the complaint here.

From the DOJ Press Release [0]:

"Justice Department Sues Visa for Monopolizing Debit Markets"

"Filed in the U.S. District Court for the Southern District of New York, the complaint alleges that Visa illegally maintains a monopoly over debit network markets by using its dominance to thwart the growth of its existing competitors and prevent others from developing new and innovative alternatives."

0 mentions of the word "credit" 27 mentions of the word "debit"

I'd love for this lawsuit to be about Credit Card fees, but it appears be limited in scope to debit card fees.

jonwachob91··on Road resurfacing during the daytime without stopping traffic [video]
Plenty of interstates have a two-tier lane system, one tier with lots of exits, and an expressway tier with fewer exits/entrances. That is not a new innovation.

jonwachob91··on Vets fret as private equity snaps up clinics, pet care companies
Just a spot check - but a DVM at the University of Florida (the first vet school that popped into my head) is $30k/year for tuition and books. At 4 years, that's a $120k degree - but from my understanding, starting a vet practice is over a $1MM, so it's safe to assume buying an existing vet practice is at least $1MM, and I don't think $120k in debt would be THE limiting factor for buying a $1MM+ practice. (and that's assuming a recent DVM vet buying the practice, not a 10+ year experienced vet that's probably already paid off their student loads)

jonwachob91··on U.S. is said to open criminal inquiry into Boeing
>>> Inquiries won't help if they stop at Boeing, or contractors Boeing used.

The investigation hasn't stopped at Boeing nor Boeing contractors.

It's not covered in the NYT article linked in this HN topic, but the Wall Street Journal article that was first to report the Justice Department investigation says the NTSB is "seeking to interview Federal Aviation Administration Officials in the Seattle area who oversee Boeing's manufacturing".[0]

Sounds like an initial step towards identifying any fault that lies with the FAA and FAA oversight.

jonwachob91··on Alexei Navalny has died
>>> The US cannot be trusted to fulfill it's approved upon role in NATO if and when the push comes to shove (that damage to the US reputation is done).

What role as the US failed to fulfill in Ukraine? Ukraine isn't a NATO member, the US had no obligation to come to their support, yet we did anyways.

Meanwhile Germany divested their entire domestic energy security and became subservient to Russia for energy - enabling this entire conflict b/c Russia felt Europe became addicted and depended to Russian fuels and wouldn't oppose their dealers.

jonwachob91··on Cloudflare defeats patent troll Sable at trial
Issuing a license is a form of "using it" in a use it or lose it scenario.

Those are not patent troll companies. Patent troll companies file patents and then sit on the patent until they can sue another party for infringement, and never make an attempt to commercialize their patent.

Another example of not using it in the use it or lose it scenario is Pfizer's acquisition of Esperion Therapeutics in 2004. Esperion was developing a competitor to Lipitor, so Pfizer purchased Esperion for $1.3BB and shelved the technology to prevent competition with their best selling drug. Had Pfizer "lost" their patent for failing to commercial Esperion's drug, that drug could have entered the market as a generic to compete with Lipitor and severely reduced the cost of statin drugs for consumers.

jonwachob91··on Toyota cashes in on booming hybrid sales
Part of why I purchased a Toyota Tacoma last year was b/c the tech isn't the "latest and greatest" on the market. I can expect this vehicle to drive for 500k miles (more realistically, 10 years at 250k miles before I'm ready for a change, we'll see) and I can expect for the tech to last just as long. I have zero faith that a tesla's tech will hold up for 10 years, or have any resale value in 10 years. I also feel confident I can fix most of the issues that will occur with this vehicle. Sure, it's still a modern car and fixing anything will require a few hours of removing other parts to get to the broken bit - but that's still easier to fix than something going bad on some of these super tech'ed up vehicles.
jonwachob91··on China Added More Solar Panels in 2023 Than US Did in Its Entire History
Hey!

Obviously I don't know your specific needs, or what quotes you got. But I'm willing to venture a guess that you got quotes from the standard solar companies - the ones that serve as all in one stops, project managements, permitting, purchasing, installing, etc. Those services are nuts!

I got a bunch of quotes from many of those types of companies for my own home a few years ago, and they all quoted me around $45k (+/- a few grand depending on the company). Realizing that was way to expensive, I put in a little elbow work and was able to come up with a quote for $18k to do the project management myself - I found a solar reseller (solarwholesale, no idea if they are still around) that quoted me $12k for the panels and installation hardware, plus they'd provide the architecture documents I'd need for permitting, the company that most recently installed my new roof quoted be <$2k to install the solar panels (just the hardware, no electrical connections), I spoke to a local electrician who quoted me ~$2k to do the electrical connections on the panels, the fuse box connections, and connection to the grid, and the remaining $2k was for miscellaneous things like permitting and other things I don't recall exactly.

It was work, but it was work well worth saving $27k compared to what the one-stop-shop solar installers want.
