Yes, but not all clients expose dependent tasks (which is sadly a common issue with open standards: they aren't always properly implemented). I'm using Tasks.org on my phone (which supports dependent tasks), synchronizing to a Nextcloud server with the Tasks app (which supports dependent tasks now, ~~but didn't for a long time~~), which also syncs to Thunderbird (which does not appear to show dependent tasks as dependents).

Edit: remembered that the Nextcloud Tasks app has long supported dependent tasks. I was thinking of recurring tasks, which it does not support. Again, open standards aren't always fully implemented.

I think CalDAV (which uses the iCalendar format) may be the closest thing. It covers calendar items, obviously, but also task and journal items.

The original blog post (linked in the article) refers to this as a DynaRec, i.e. a dynamic recompiler. So it's not exactly emulating, but nor is it the ahead-of-time recompilation that Rosetta 2 can do.

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

The Atlantic had a good article on this a couple weeks ago (no paywall). It sure feels like a move in the wrong direction, but the authors note Oregon's overdose deaths grew way faster than the rest of the country after decriminalization. Their take is that Oregon already had pretty good laws place, and that a little bit of a legal threat can help to encourage addicts to seek treatment (and that the treatment system needs to be better funded).

Aaron Wherry, the author of the article, does that a lot. In my opinion, he regularly does a good job of covering all the facets of difficult issues.

I work in railway noise and vibration mitigation, and @scrion@lemmy.world has given you a great starting point. When we build rails and want to mitigate ground-borne noise and vibration (typically up to ~200 Hz), we generally mount the rails on soft pads and add extra mass to isolate the rails from the surroundings. The exact same approach will work at your computer. We don't typically use tuned mass dampers for ground-borne vibration, so I think that will be overkill for you, but you can try if you like.

I wanted to suggest that, in addition to the feet/foam/plywood, you can also add a big chunk of something heavy to help with isolation. Like put a heavy rock on top of the foam, and your computer on the rock. The trick is this: if k is the stiffness of your foam, and m is the mass of everything on top of the foam, then your isolating frequency is at √(2k/m). All frequencies above the isolating frequency will by mitigated (the further above, the more they're mitigated), while all frequencies below will be amplified.

(Quick aside if you actually want to calculate frequency with √(2k/m): check that your units for k and m are compatible, you should end up with a result in units of 1/s, which is actually radians per second, then multiply by 2π radians per cycle to convert to Hertz).

When it comes to measuring results, since your problem is in low frequencies, you can probably use your phone's accelerometer assuming it reads fast enough (the sample rate must be at least double the highest frequency you care about). Mount it as rigidly as you can to your computer, since if the connection is soft, the phone will be in its own isolating system. The quickest way to test your isolator would be to hit close to the base with a hammer; impacts excite a wide range of frequencies equally, so in the frequency domain you should see vibration amplitudes following a shape something like these.

But as @scrion@lemmy.world notes below, you don't really care about your isolator's response, you care about what trains are doing to your computer. However, he said one thing I disagree with: it's not the amplitude of the acceleration that you care about, it's the amplitude of energy, and therefore velocity. This article gives a good introduction to ways you could analyze that. But now we're getting way in to the weeds on what should be a simple project!

One last aside: if the vibrations in your building are bad enough, you could raise it as an issue with the metro operator. The US Federal Transit Administration sets standards that are commonly followed even outside of the US (see Table 8-1 in their Noise and Vibration Manual); if your measurements show vibration exceeding those limits then they might pay me to fix it :D.

I really wish that list would include some explanations about why each line is a falsehood, and what's actually true. Particularly the line:

The software will never run on a space ship that is orbiting a black hole.

If the author has proof that some software will run on a space ship that is orbiting a black hole, I'd be really interested in seeing it.

On openrailwaymap, you have to zoom in pretty far before smaller branch lines are shown. That might be why this map looks to have extra lines.

You must be thinking of a different grant, or you're in a province where the carbon price is not federally run. The federal Climate Action Incentive payment is disbursed to everyone.
