0x53··on Homemade Heat Pump Manifesto (2009)
I have been doing a ton of research on building my own GSHP lately and so this is a great resource!

However, what I have found in the process is that for well insulated homes GSHP probably doesn’t make sense.

Originally I was considering buying a kit from this site: https://www.123zeroenergy.com/pricing/geo-thermal.html

But like it says on the page, because air source heat pumps have been getting a lot better they no longer sell the kits. There are a couple of individuals on YouTube who have used similar GSHP kits and had good success. The main challenge is that you need to dig 100ft of deep trenches per ton of cooling. Edit: should be 300ft not 100

I do this too. My banks mobile app takes just seconds to unlock the card.

Look into the sondors meta cycle. Around $6500.
0x53··on Solar canopies on parking lots
Been thinking about this a lot recently, I guess the hurdle to clear is probably convincing Walmart to let you put solar panels over their parking lot. I wonder what the economics of it would be if Walmart did it themselves?

Tangential, the reason that we have so much parking space (as the article mentions) is that it is dictated by law in most places how many spots are required based on the building size. https://www.strongtowns.org/parking

0x53··on Librarian's Letter to Google Security
Obviously, it would be better if Google would do something, but they won’t. A temporary solution could be something like a sign that encourages people to print out backup codes and the librarian could help them with it. Maybe the librarians could even store them in a folder and retrieve with ID. Not saying these are good solutions, but they could maybe help a bit.
0x53··on Efficient dehumidifier makes air conditioning a breeze (2014)
There is a great podcast by a company called positive energy that covers a lot of topics relating to this. Here is the one on how important dehumidification is to cooling: https://positiveenergy.pro/building-science-podcast/2021/11/...
0x53··on Half of Americans anticipate a U.S. civil war soon
It’s hard for me to gauge the difference in attitudes now and in the past. Things seem worse now, but maybe that is just because I’m more aware.

0x53··on Thoughts on the potato diet
In regards to the first point. For the year of 2021 I did not eat any added sugar. If the label said any grams of added sugar I just didn’t eat it. Super easy diet and it worked really well for me.
0x53··on Abolish Zoning
There will always be suburbs because a lot of Americans want suburbs (see this thread). America has plenty of land and so if people want suburbs and there is plenty of land to build them I don’t see them going extinct. In other places in this thread people point to places like Japan lacking suburbs, but the difference is that America is huge. If we allow denser zoning there will come a point at which enough dense housing has been built for the people that want it, right now that isn’t possible because it isn’t allowed.

You said “if you don’t like it don’t live there”, I’m saying that I would love to live somewhere besides the suburbs, but as others have identified most nice areas that are dense walkable are very expensive because they are no longer legal to build

0x53··on Abolish Zoning
So, if we allow people to live closer together there will somehow be less space?

There will always be suburbs in America. If people want to live in the suburbs it will always be possible here. Zoning actually prevents people from living where they want to because only single family homes are allowed to be built.

$25k / 12months / 9 years = $230. Which seems reasonable.

Visited last year and tried to stop, the line was so long that we gave up and just bought it at the grocery store. Still very good.
0x53··on A Note to the Celsius Community
I bought a lot of bitcoins that were locked up in mt gox. The lawsuit has been ongoing in Japan for many years now. Every 6 months or so they say they are just about to pay out the claims.
0x53··on DOE announces breakthrough in residential cold climate heat pump technology
They way it works in practice is that the air handler that comes with the heat pump will contain a backup emergency heat element in case it gets too cold or there is a problem with the heat pump. The cost to run it is much higher, but it should only run in the most extreme cold temperatures.
0x53··on I've locked myself out of my digital life
I use a variation of the USB to a friend method that I call horcruxing. Several USBs distributed to different friends that contain enough info for me to get back into my cloud synced password manage (plus a copy of all the passwords I have at that time). The USB is encrypted with a password I have memorized.

0x53··on Luna Cryptocurrency Collapse: How UST Broke
People have been concerned about this for quite some time. It seems the answer that question is definitely not. Here is a somewhat dramatic write up: https://www.singlelunch.com/2021/05/19/the-tether-ponzi-sche...
0x53··on Luna Founder Requests Police Protection as Investors Are Visiting His House
Yep that’s essentially how it works. However, it can be risky either way. For instance, what if the price of Luna had gone up massively? Well then you would have had to repurchase Luna for a lot more than you sold it for. Basically, it reduces down to the exact same scenario as shorting a stock.
0x53··on Luna Founder Requests Police Protection as Investors Are Visiting His House
Certain application in the decentralized finance space will allow you to borrow a cryptocurrency based on collateral in another currency. So in this case you deposit bitcoin and get Luna out. Then you sell the Luna. Then after the price crashes you buy Luna to repay your debt. Basically shorting Luna
0x53··on Some interesting malware I found
I had a similar experience with my significant other. Instead of typing "selectmedical.com" she didn't type the "c" and got "selectmedial.com". It prompted her to install a browser extension "necessary for the site to work". I imagine that the authors partner did something similar.

Wow. Didn't watch the super bowl this year, so this is my first time seeing that ad. That is incredibly depressing.

I like this. I have really terrible willpower, to be able to set rules for what I want to do without having to consciously make the decision each time sounds great
0x53··on Malware Could Use SSD Over-Provisioning to Bypass Security Measures
The title is a little misleading. This is not a discovery of malware, but rather a theorized capability that malware could use.

Link to the paper on which this is based: https://arxiv.org/ftp/arxiv/papers/2112/2112.13923.pdf

It appears as though the attack is based on the assumption that you have admin level access to the computer.

0x53··on Census Bureau’s Survey Shows Significant Increase in Homeschooling Rates
I was homeschooled. I played soccer throughout highschool for the homeschool soccer team, played in a youth orchestra, took classes at a homeschool co-op and then local community college. My family also did a lot with our local church. Once I graduated and went to a 4 year university I definitely liked the increased social interaction, but I had plenty in high school.
