Problem is, the way economic activity is organised in general, there is no transition path from complex bloated systems to well designed completely human auditable systems. For example given the inherent (and proven) security risks of the Wordpress ecosystem, nobody should run WP anymore.

Thanks for researching. Maybe I failed to give microphone access to phyphox which in my understanding of the source you pointed to limits sensor update rate. Sounds like me because I never grant access for anything I don’t plan to use.

If your sample rate is 100 Hz you would usually apply analog lowpass filtering at around 40 Hz, well below Nyquist. But with enough load on the line, since no filter has perfect attenuation in the stop band…

That is a possibility, didn’t check

It is a Samsung a16 and it is just an observation I made, not a problem at all. If it was, I would try another installation source or even switch to a degoogled OS first to get more control over the hardware. Only thing I tried to get more samples was fiddling with the App restrictions. But it really doesn’t matter at all.

I get 100/s on an iPhone SE2. 50/s on a Samsung Galaxy A16 which was released in 2024 or 2025, but that is due to an API restriction. You can export from phyphox (.xslx or .cvs). You get timestamps in the first column. Phyphox refers to the raw data rate, not Nyquist freq.

The sensors have analog lowpass filters that can be adjusted in order to avoid aliasing.

In general, with more bandwidth you can do more intrusive things. But if you want to tell wether two people ride in the same car, 50 Hz should be sufficient anyways.

Phyphox has a smartphone sensor database:

There is a paper you can cite if you use phyphox professionally.[1]

In Germany phyphox is quite popular in physics education.

However on android the sampling rate of the acceleration sensor is limited to 50/s. At least if you install through the official app store.

You need a lot more impulse and more fuel to go twice as far. Probably more correction burns. A longer final burn before entering the atmosphere. So the risk of loosing the engine is much higher and probably increasing more than linear with burn time/change of impulse.

Wouldn’t the soviets or any other adversary prepare against letting NASA capture their satellites? You need a very small amount of C4 in the satellite to destroy the shuttle in the event of capture. Tampering with other entity‘s satellites can best be done with satellites. That also frees resources needed for bringing life support systems to orbit.

Yeah well the standard degrowth argument against the efficiency camp is that more efficiency has always led to more resource consumption, not less (rebound effect). At least in capitalist markets. The current 'AI' boom, which is very relevant to resource usage, was only possible because integration and energy efficiency of graphics cards became efficient to a degree that was enough for neural networks to do anything meaningful with text.

There is a range header in the http specification for resuming downloads at a certain part of the file. Since http is stateless, you can download precisely what you need right away.

Pretty expensive though. Lab costs in Germany are <20 € for a quantitative test and the cost of the physician for taking the sample is usually covered by insurance.

Très cool.

A grid of capacitive touch sensors could be printed directly on the pcb, bringing down costs by a degree of magnitude. Real switches are much more satisfying though.

I can’t obviously. But if they don’t have enough, despite massive overdosing for years, that would be very surprising. (The test only shows one of three possible outcomes. It is not a quantitative procedure.)
