I removed it to see what happens :) The reason I added it in the first place is because I've seen failures from uneven PCB heating. It's not the components themselves fail, but radiators get unglued and PCBs can get damaged.

In-person tests and workshops, including oral exams. Like we'd been doing for literally hundreds of years.

I'm worried about long-term thermal wear from uneven heating, so I switch the current direction once a day. Simply because that's the maximum time I can set on a time delay relay that controls it.

I read "Triumph of the City" about 15 years ago. It's a well-researched book, and it literally makes the same points as I do. In particular, it describes the density death spiral much better than I can. It's a bit outdat

I have thrown out my Tripplite UPS because its battery has degraded to the unusable levels. I replaced it with a 5kWh LiFePo4 rack-mounted battery and an AIMS rack-mounted inverter. I'm really surprised that there are no off-the-shelf

You actually can run most ATX power adapters directly from 96V DC! You can get that by connecting two 48V batteries in series. They do rectification as the first step anyway, and then they use high-frequency switching that works just fine w

The thing is, I don't actually know good sources that aggregate all this data. I'm collecting all the references and I'm planning to write a book.

Care to explain the cherry-picking? The average square footage was growing steadily (except for the 2008 crisis) and the inflection point happened around 2012 when the death spiral started in earnest. It has been on the downward trend since

Try rosin flux, it smells actually pleasant! A lot of initial soldering mistakes are from using incorrect temperature, not cleaning the surfaces with flux, or from using wrong tips. You do get better rather quickly, especially if you ask fo

Yup. They specify 3 seconds, but that's for 350C. In my experience, it's always at the right temperature by the time I finish picking it up. It has a 240W power supply, so it's not just marketing.

This is not "economy of scale", this is more of a "pollution death spiral" and "unpriced externalities". A factory that dumps raw waste into rivers is more efficient and can produce widgets more cheaply than a

There is not a lot of good literature, actually. I'm not saying anything even remotely factually controversial. Housing units per household: https://fred.stlouisfed.org/graph/?g=15tRv It's also not controvers

It creates for companies more incentives to move to these areas, as they have easier access to a larger talent pool. Which in turn makes housing there even more expensive.

No, it's not. Austin's population growth has been at _best_ stagnant. And I made a prediction that it had actually decreased. We'll see once 2025 ACS data is released.

The answer is "no". That's because WE DO NOT HAVE a housing crisis. And yes, I'm not crazy. We have 1.1 housing units per family right _now_. We likely will have the record number of housing units per capita within about

Well, the US auto execs visited China and realized that their days are numbered. So why not extract as much profit as possible? Firing people with institutional knowledge? So what? It's going to improve profits short-term.

The problem with erasure coding is that if a disk fails, you suddenly need to read 3-5x more data to reconstruct the missing data from parity blocks. This is especially problematic if your replicas are split across zones. The inter-zonal ba

Yes, and S3 is multiply redundant and is designed to survive a total AZ failure. So your data is physically replicated into at least 2 different AZs and might be multiply-redundant within them. They also provide a crazy SLA for data integri

Looks like there are none, which is the typical result. If you worked in a drug-discovery-adjacent field, this is an utterly normal scenario: 1. University/startup company finds a promising drug candidate that works in-vitro. They make

S3 is pretty competitive if you want similarly-performing storage with consistent millisecond-level latency, high scalability, and at least 3x redundancy. Try looking at how much it's going to cost you in enterprise SSDs :)
