animatedb··on A room-temperature superconductor? New developments
Superconductor means low resistance. Low resistance means less loss due to heat on a wire. Room temperature superconductor also means more efficient magnets for motors, coils, ending up in cars, MRI machines, etc.
animatedb··on So long and thanks for all the bits
I want the hardware to protect me perhaps with a key or handle or something. Talking to the hardware: Give me a block of memory that I can append to the end of. Another piece of code: Allow me to access that other block for read only. Each piece of software has some sort of identification. Then the hardware throws an interrupt if a piece of software uses some memory incorrectly.
animatedb··on Nuclear-Powered Cardiac Pacemakers
There are now leadless devices that communicate with each other using RF.
animatedb··on 134.5 kg Concrete Bike [video]
You are thinking much too small, friend. Spin the earth faster and we can finally get rid of leap seconds.
animatedb··on “Atari Was Very, Very Hard” – Nolan Bushnell on Atari, 50 Years Later
I actually fixed one of those games once. It was really easy since both tanks had duplicate hardware, so signals could be compared between both tanks.
animatedb··on Modern Python Performance Considerations
If you are talking about large sets of numbers, then the speed up will be far below 1%.
animatedb··on PC DOS 1.1 from Scratch
I imagine you may know a lot about this, but what OS/machine were they using to develop it? PDP-11?, CPM? What editors did they use? Line editors? Which machines did they use to test on? Most drives and even RAM was unreliable back then and everything was small. I imagine there were plenty of obstacles back then. I remember using CPM where floppy disks had to be swapped between the editor and compiler, and your program may fit on another floppy disk.
animatedb··on Phones containing magnets inhibit implantable cardioverter defibrillators
The magnet is usually used as a mitigator to turn off the device in case the device is doing something wrong like producing pulses too fast. There is typically RF communication that can communicate to the device and can often be used to turn the magnet detection off, which means that the device will not quit working when a magnet is detected. This was used in the past for electric trains or other large magnets such as in factories.

animatedb··on SQLite is 35% Faster Than The Filesystem (2017)
I know that the open function on files is very slow. This makes opening many small files very slow.
animatedb··on Global rich must cut their carbon footprint 97% to stave off climate change
Typically it is not ok considering cradle to grave of all materials, labor, transportation, etc.
animatedb··on Let there be more biographies of failures
Or a bit of the ego of the writer is getting in and becoming the story.
animatedb··on Beyond Meat signs global supply deals with McDonald’s, KFC and Pizza Hut
To be honest if it wasn't so good, we wouldn't have evolved to consume so much of it.
animatedb··on Ask HN: What are you working on?
Allow people to vote and follow different bellwether classifications.
animatedb··on Python overtakes Java to become the second-most popular programming language
I like it a lot. Use it with --disallow-untyped-defs to make sure more is caught.
animatedb··on YouTubers are upscaling the past to 4K, but historians want them to stop
You may have missed one more part. When you see a black and white picture, you assume that the black, gray and white are not real. When you see color, it biases your brain to think the color may be close to correct.
animatedb··on Answers to a reader's questions about bits of tech
There is the mypy static type checker that works very well with Python. It works with the typing module that allows unions of types, and other methods. Using the --disallow-untyped-defs command line argument provides more checking. A function prototype could look like the following where the str and int are the types.

def strlen(check_str:str) -> int:

animatedb··on One Man’s Quest to Outrace Wind (2011)
When I was a kid I used an erector set to make a car that moved directly into the wind using a similar technique. Many people don't think that is possible either, but with proper gearing, it works fine.
animatedb··on FBI: Companies should help us ‘prevent encryption above all else’
How much money do you have in the bank, and what is your bank account number? If anything can be hidden in the internet, then who decides which things can be hidden?
