I still don't follow. As market rent goes up you will be renting to yourself below market rate. Suppose market rent is $2000/month and my mortgage is $2000/month. In 10 years market rate rent has gone up, but my mortgage is s

I'm not forgetting. I have to live somewhere. If I pay rent somewhere else I'm paying market rent. That is the gp's point.

You miss something important: If you finance a house on a fixed rate mortgage you lock in your monthly cost. Market rents will continue to rise, the value of your property will continue rise, but your cost will not change (modulo increases

A timestamp is sensible if reproducibility isn't your goal, and exact reproducibility of build artifacts was never a goal on any of my projects. It was simply never a priority.

Every significant project I've worked on embedded the build host and build time in the resulting executable or firmware image. This was along with other static build information, like version number, compiler version and build flags. O

I didn't spell everything out. I never suggested you store the electricity in batteries. The electric heater would be used to heat some mass, like a tank of water or bricks. I look at this impeller and I see a custom mechanical design,

This impeller design is clever, but it seems that a DC generator and a resistive load would be an easier way to brake the windmill and generate heat. The first advantage is off-the-shelf parts. Electric generators and resistive loading are

Yes, and then the model will give you some result, but you will never know if you are accurately accounting for reality in all its complexity. The more complex your model, the less likely you are to match reality precisely. To quote a clich

Looking at this reminds me of reading Scientific American when I was a child. The articles were in-depth, scholarly, and often difficult, even when simplified for general consumption. I know Scientific American changed its format to survive

When I joined a particular startup 4 years ago I was surprised that they owned their own servers mounted in racks in a rented colo. I was all, how retro! But then the head of IT showed me the cost savings over AWS and how he orchestrated it

Customs in the US is a two-tier experience: with Global Entry (which isn't that expensive or hard to get) you just glide through, even at SFO.

My doctor did leave the PD off the prescription, but I just called the office and asked for it. To their credit, they looked it up for me in their records.

TLDR: Old Thinkpads are powerful and rugged, but the screens are terrible. A wistful story: I used a Thinkpad X201 (2010 model) as my primary laptop for 6 years. I called it "lappy" (yes, a homestar runner reference). That thing t

All you're talking about is metabolism and respiration. All metabolism oxidizes fuel (broadly speaking, fats and sugars) and generates C02. Excluding anaerobic metabolism, which only happens in times of heavy exercise or hypoxia, all m

Exactly! I made the same calculation 8 years ago, though now the cost Apple hardware has me reconsidering a PC with Linux for my next personal laptop.

That's not why companies don't develop Easter eggs. It's because: 1) Easter eggs are features. 2) Features cost time and money. 3) Features almost always also add bugs. 4) Easter eggs usually aren't in the test plan. Wha

You're mixing up NAT and ingress blocking. A stateful firewall doesn't depend on NAT, we're just used to ingress blocking as a side effect of NAT.

I am also suspicious of public usb charging ports. That's why I prefer to use my AC power adapter. Not only do I make sure to get full USB-C power capacity, I know nobody can hack my phone because the AC port has no data channel.

Simply compiling with gcc on a single architecture (no cross compile) requires more than one binary. In my experience (20 years of embedded work), cross compiling is hard not because of the compiling, but because of the linking. The linker
