eric-hu··on How to drill your own water well
Right, I could have stated more explicitly. Watering possibly edible plants with pathogen polluted water seems okay. Watering them with chemically polluted water seems like maybe a way to ingest toxic stuff. Washing dishes seems dicey too.

A Gaiwan is one traditional Chinese way of making tea, but those words are literally “covered bowl”. If you don’t want to buy one, you could makeshift your own: brew loose leaf tea in a cup or bowl and pour it into your drinking cup using a small plate.

I’m curious: if the water isn’t considered potable, would you want to be watering plants with it? Is the contamination more often bacterial than chemical?

eric-hu··on SUSE to go private
You just educated me on Michael Dell taking Dell private again. I didn’t realize he did so with the backing of PE.

eric-hu··on Water Cooled Rooftop Solar Panels
In addition to this, tank water heater systems include a sacrificial anode rod.

Water heater tanks include different metals in contact with the water, which creates a galvanic cell. Over time this corrodes the least noble metal. The rod is added in the design to corrode before pipes do. The rod is usually magnesium, aluminum or aluminum-zinc. It slowly but steadily leeches out the rod metal into the hot water supply.

I appreciate clean emissions, but I’m skeptical this will happen in 13 years time. Are there similarly ambitious programs that have worked in CA’s past?

eric-hu··on TSMC faces $70M ransom demand following lockbit cyberattack
Apparently there was someone who claimed Taken was based on him. It was a case of fraud though.

https://en.wikipedia.org/wiki/Taken_(film)#Controversy

> In 2011, a self-proclaimed counter-terrorism expert was convicted of wire fraud after claiming the film was based on a real-life incident in which his daughter was killed. William G. Hillar, who pretended to be a retired Green Beret colonel, claimed to have spent more than 12 years lecturing US government agencies such as the Federal Bureau of Investigation on security issues. However, records revealed he had actually been a radar operator in the Coast Guard Reserve between 1962 and 1970, and had never been in the US Army. Nevertheless, his website claimed Taken was based on events involving him and his family. Hillar, who admitted the charges, was sentenced to 500 hours of community service at Maryland State Veteran Cemeteries. He also agreed to repay $171,000 in speaking fees that he had received from various organizations to which he had presented himself as an expert in terrorism and human trafficking.[29]

eric-hu··on Debris found came from missing Titan sub, says friend of passengers
There’s a series of episodes of Smarter Everyday where the host goes on a US nuclear submarine and interviews the crew and shows some of the equipment. In one of the episodes, they talk to navigators, who explain that submarines can be invisible to sensors in certain locations because the ocean water is not uniform. Temperature, currents and salinity vary, so a sound could be attenuated in some directions.

eric-hu··on Everything must be paid for twice (2022)
It really depends on where you live. I lived in Taipei and cycled around everywhere in that city. There were sometimes bike lanes on the street, and sometimes wide sidewalks with bike lanes, and sometimes neither. Drivers were pretty reasonable most of the time. I felt I could manage the risks by cycling conservatively and assuming drivers didn't see me.

I'm in Los Angeles now. While I miss biking dearly, I look at drivers around here and just think it's a matter of when, not if, I'd get into a cycling accident if I tried to ride within a few miles of my home.

AAA will change a tire for you, and I've driven past plenty of service calls where I saw exactly this happening. Also, run-flat tires are a thing.

I get where you're coming from. People in the US mostly don't put in time to learn the ins and outs of vehicle maintenance. They want turnkey personalized transit and turnkey maintenance. I've just accepted that as the state of how things are.

One thing to add is that if you value the learning from trying a repair job, doing it on a problem in front of you is close to free. Taking a class would cost money.

I would be pretty surprised if that happens. Digg sold for $500k. I'm expecting something similar.

eric-hu··on Reddit stripping moderators of rights and forcing subreddits to go public
But to your point, why would anyone put their own content on a site they don’t own?

> "if you don't own the content, it can be taken from you at any point, for any reason, and you have no recourse"

Fully embracing this idea means one shouldn’t participate in any community where one isn’t an admin.

eric-hu··on Apollo’s Christian Selig explains his fight with Reddit – and why users revolted
Apollo sold subscriptions for up to a year, and they would’ve had to burn money to honor those subscriptions. The cost was in the millions.

They did ask for more time for the changes than the given 30 days, and Reddit refused.

eric-hu··on Apple Introduces M2 Ultra
> As for the haptic feedback, it felt a bit off. Earlier MacBooks had a satisfying clickiness and responsiveness, but that didn't seem to be the case with the current model I tested. I suppose this could be subjective, and perhaps some may prefer the current haptic approach.

I think there was a change in Apple's trackpads around 2015-2017. I'm going off memory, but prior to that, the haptic feedback was more like a motor, and after it was something more like a speaker. I noticed it because I had a 2012 Macbook and bought a Magic Trackpad, and the click had a noticeable difference.

> The two-day blackout isn't the goal, and it isn't the end. Should things reach the 14th with no sign of Reddit choosing to fix what they've broken, we'll use the community and buzz we've built between then and now as a tool for further action.
