Excuse me, that was Finn’s right arm.

I’ve noticed that, if an equation calls for a number squared, they usually really mean a number multiplied by its complex conjugate.

It sure feels like we’re at the peak of the Gartner hype cycle. If so, the bubble will pop, and we’ll end up with AI used where it actually works, not shoved into everything. In the long run, that pop could be a small blip in overall development, like the dot-com bust was to the growth of the internet, but it’s difficult to predict that while still in the middle of the hype cycle.

Relevant XKCD. Humans have always been able to lie. Having a single form of irrefutable proof is the historical exception, not the rule.

You’re correct. You’ll notice every president in recent history has multiple assassination attempts listed. The bulk of them don’t go very far.

Technologically, I2P handles large data transfers much more efficiently than TOR. That makes I2P useful for torrenting large files like Linux ISOs.

And yeah, it did used to be a lot more common. And before that, it was a medical term.

It’s the euphemism treadmill in action.

K-9 mail… isn’t supported or being developed any more.

That’s not true. They make frequent-enough releases, they post monthly progress reports, and they are actually going to become Thunderbird’s Android version.

Having said that, I almost switched to FairEmail because K-9 lacked support for some sort of authentication measure (which I no longer need), but that wasn’t because K-9 stopped development.

Calling workers “heroes” leads to them getting paid less.

If you want a preview of an uncaring and anti-consumer Valve, look no further than the company’s efforts on Mac.

Valve never updated any of its earlier games to run in 64-bit mode… Apple dropped support for 32-bit applications in 2019

Funny enough, the only platform with a 64-bit Steam client is Mac.

I don’t disagree with concerns about monopoly, but the author’s key example is Macs. And from the example, it sounds to me like Apple disregards backwards compatibility (dropping 32-bit support, moving to ARM chips) and Valve isn’t investing to keep up. Meanwhile, Windows has a heavy backwards-compatibility focus, and Linux isn’t too bad either, so no wonder they still get Valve’s attention. So who is being “anti-consumer” in this example, Valve or Apple?

You know, you have a point. But I’ll note both instances had the UN request NATO intervention. Russia could have blocked either with their veto in the UN Security Council, but they didn’t.

That’s how Putin claims to perceive it, but that’s also what he would claim if his actual goal was to control his neighbours by force. And don’t forget Finland and Sweden responded to the invasion of Ukraine by joining NATO. If Russia perceived NATO as a threat, then Finland joining would make them more likely to be attacked. Clearly Finland feels NATO is making them safer or they wouldn’t have joined. And since then, Russia has moved tons of their military away from NATO borders and into Ukraine.

In other words, I trust the actions of Finland and Russia more than I trust the words of Russia.

Basically they don’t want NATO right on their doorstep.

NATO is not the anti-Russia club. They’re a defensive pact. Why would you be concerned about your neighbours agreeing to defend each other? Like a neighbourhood watch, perhaps. Maybe you’d be upset if you’re planning to do the thing they’re defending against. Which is all the more reason for those neighbours to band together.

Forcing people to give up their language and culture can be considered cultural genocide. Cultural genocide is not included in the UN Genocide Convention, so the definition of cultural genocide is not universally agreed upon. But the UN Genocide Convention does include “Forcibly transferring children of the group to another group” in its definition of genocide, and Russia is not shy about their relocation and adoption programs, so we can pretty definitively say that Russia is committing genocide in Ukraine.

Thanks for the update and graphs. That is an amazing improvement. In the “after” plot, it looks like any acceleration from the train is well below the noise level of your accelerometer. So, within the limits of your measuring equipment, you’ve effectively eliminated all train vibration. If I were in your place, I would declare success and move on with life! Don’t even bother with foam and rubber feet, because this configuration is working great.

But you could analyze further if you really want; there could be some train signal hiding in all that noise. Since there’s periodic noise in the Z axis, you could take a reading during a still time (computer off, no trains) and see where your spikes are in the frequency domain. Then you could apply a filter (or filters) to cut out that periodic noise.

But unless you’re really into learning about signal analysis, I’d say you could skip it.

None of the included experiments look to be exactly what you need. For characterizing your isolator, the included Acceleration Spectrum is close, though it records continuously, making it difficult to use to record impact response. For evaluating actual train vibrations, the user-defined Integrated Acceleration might be a start, but it doesn’t include the filtering needed to get good information. You could define your own experiments, but that’s probably even harder than analyzing the CSV data on your computer. At least on your computer you can change your analysis freely and immediately see results, rather than re-running the experiment every time.
