Anti-tremor engineering
https://youtu.be/SiWKmoLqlRg?si=wiAMEY1X98So36CP
Desperately trying all kinds of engineering to offset a hand tremor. Very challenging to make it lightweight, portable, durable, and waterproof.

Water-jet loom

A modern loom is a jet of water to send the yarn across the fabric. Cool! And probably a lot now efficient.

Murder confession
https://youtu.be/jJZv3z7FOt0?si=1Y5kEdybcOdfCiR-
I find it morbidly fascinating how well this man disguises his guilt during the questioning, into he's confirming with incontrovertible evidence.

Pet peeves with Tesla
There used to be an on-screen "gear-icon" button to ignore navigation directions but continue FSD; navigation often insists on a route that saves only a few minutes but has more intersections and side-roads, or insists on a lane change for no apparent reason consistently at the same location. Being able to negate these consistent nuisance navigation deviations without stopping FSD would be a huge relief and benefit.
Also, a small thing: Somewhere to place a grocery bag so it doesn't fall over.
During FSD, the necessity of turning the steering wheel every 30 sec or so is tiresome; I've decided pulling on the FSD control lever is easier. I just wish that pressing the accelerator briefly, or some other easier method of acknowledging you are actively supervising driving would be much more pleasant.
Also, better functioning of FSD during heavy rain (common in the Pacific NW) would be welcome. If some means of automated cleaning of the side cameras could be engineered, like a spinning glass cover that ship's bridges have, would be a huge improvement.
Can solar power the Tesla for a 30-mile commute?
This calculation assumes a lot of things about how much sunshine you get each day, and how efficiently you drive, but they calculate 11 panels of solar.
"If the Tesla's mileage is around 30 miles per day, it would consume 7.8 kWh every day according to the 0.26 kWh per mile range. The optimal DIY charger for this Tesla model would be a Level 2 AC charger (240V).
To achieve the 7.8 kWh or 10 kWh each day, 16.67 kWh is required in solar energy every day. In addition, +50% power requirements apply as well as 90% battery and inverter efficiency.
This goal requires 11 solar panels"
Low Cost Rainwater Harvesting: An Alternate Solution to Salinity-Affected Coastal Region of Bangladesh
"Bangladesh located in the same zone. The Satkhira district averages nearly 1,710 mm rainfall per year...minimum catchment area was assumed to be 6 m2 and storage tank of 2000 liter capacity...approximate cost was assumed to be $171 for building and operation of the whole system."
"a family consisting of five members having water demand of 5 l/capita/day for 3 months (for only drinking and cooking purpose) was considered...dry spell period in the region is around 45 days...So, sixty days demand is 2000 liter...storage tank is the most expensive component of rainwater harvesting system...plastic tanks are cheap...To reduce total coliform from the stored rainwater, locally made sand filter can be used." https://pubs.sciepub.com/ajwr/2/6/2/index.html
Efficient floating fish farm
Singapore floats high-tech fish farm up meet food demands.
Using 0:30 a closed-containment system that filters seawater, thus obviating the need for antibiotics in its tanks, this floating fish farm 1:36 produces 66,000 lb of fish a month, which is 20 x more per hectare than traditional open-net cage farms.
Similarly, automation has increased yield at shrimp farms, using 6:55 mangrove trees to recycle their waste water.
Advance Estate Planning for a Surviving Spouse - Schwab
in a community property state...all assets acquired during the marriage will transfer to the surviving spouse regardless of whether a will is in effect. However, for property acquired outside the marriage that isn't jointly owned—such as a home purchased by one spouse before being wed...spouse is entitled to only one-third to one-half of the property
To avoid the expense and delays of probate,
- Titled with rights of survivorship, meaning both spouses have equal ownership and the surviving spouse will inherit the deceased spouse's interest.
- Placed in a revocable trust—which isn't subject to probate—with your spouse as its beneficiary
- For bank accounts in one spouse's name, you can file a payable on death (POD) form to ensure the surviving spouse can access the account without going through probate.
In addition to your will and any trust documents, you might include a letter of intent in which you detail the recipients of particularly meaningful or valuable property.

The first stronghold of movie production was NYC under Thomas Edison, but it moved to Hollywood because of better weather, more land to develop, and no antagonistic political backlash.

Rabies on radiolab
Incredible that there's no cure.
"In terms of the percentage of people who come down with the symptoms of rabies, who die, it is the deadliest disease in the world."
"People just screaming and writhing with convulsions...from the virus's perspective, it's trying to drive its host to be more aggressive so that it bites somebody else and spreads more virus."
"they will get this fear of water, a really powerful fear of water...from the virus's perspective, why that would be advantageous. You are trying to transmit virus through biting. So, an animal who can't swallow his virus-filled saliva is gonna be like a loaded gun."
Induced coma (Milwaukee protocol) was thought to be a cure in 2004, but it turns out that particular survivor probably had previously developed antibodies enabling her survival, and "There have been at least 64 cases with failure of the protocol."
