Given how political punk was right from the start, I wouldn't call it "just a music movement".

That's actually close to a regular working day. 4-5h of core work, 2h of correspondence (e. g. Zoom meetings, bullshit emails), 1h of various breaks, e. g. lunch. Sounds perfectly reasonable to me.

Circular selection, fill?

Or, for an annulus: circular selection, border, enter border width, fill.

Or, for any selection in general: edit, stroke selection.

The moon landing was 1969, less than four years before Picasso would die at the age of 91.

I'm absolutely not surprised that he didn't care, I don't think the actual consequences / effects of the moon landing would have been readily available for Picasso to grasp (or many other people at the time).

Plus, at that age, nobody gives a fuck about anything anyway.

The tag does not say the glove is made of leather, that's simply the Franklin "leather series", a meaningless marketing term meant to trick people.

The Franklin page clearly states those gloves are made of "synthetic leather", e. g. Polyurethane, Vinyl etc.:

https://franklinsports.com/field-masterr-tan-series-baseball-fielding-glove#

Plus, the synthetic leather comes with a pre-formed pocket which is designed to break in exactly to your liking quickly and easily.

EASY BREAK IN: The soft synthetic leather material is lightweight and responsive [...]

You put a plastic glove in your oven at 350. By the way, depending on the material, in particular when talking about Vinyl, burning it may release incredibly toxic fumes, although that mostly applies to PVC. Depending on the details, I'd still considered that oven ruined though, at least for food.

I get that this sucks in more ways than one, but how the heck did you not actually check the complete material composition... almost all modern items are a mix of different materials anyway.

It's not as simple as that, which is why e. g. laws to control monopolies exist. Just look at the recent changes in rulings regarding essential services, right to repair etc.

This is really an outdated, "the market will regulate itself" perspective that has been shown time and again to not work - people just get fucked by corporations.

Even if they paid the kid only, I dunno, $100 million, how many community mods could have been paid with the remaining $93 million?

How anyone can believe that it is possible for any single person to do something so meaningful in the same 24 hours we each share every day that they deserve payment so drastically disproportionate, so...disgustingly obscene, really, is beyond me.

I'll answer this one in German since this is my time to shine. Let me just say, the wall is perfectly fine, what we see is just another layer of OSB board for ease of installation on top of the actual wall behind it (which is well framed and insulated).

Dies ist ein sehr unterhaltsamer thread fuer mich, da ich beide Seiten verstehen kann.

Auf der Webseite von Wolf Haus ist die Installationsebene aus OSB zu sehen, die angegebene Punktlast ist 70kg pro Schraube. Wenn du sicherstellst, das deine Schrauben durch die Kanthoelzer in die OSB-Platte gehen, solltest du dich auf diese Angaben verlassen koennen, also eine Schraube haelt dann 70kg.

Deutschland hat selbstverstaendlich auch eine Norm fuer Kuechenmoebel, DIN 68930. Da bekommst du ein Gefuehl dafuer, wie schwer Kuechenschraenke werden koennen. Die Nachbarn in der Schweiz verwenden die Norm SN EN 14749, zum Vergleich. Es ist nicht ungewoehnlich, einen Schrank (wall cabinet) mit 120kg Belastung zu testen.

Beachte bitte auch die Distanz der Schrauben, man darf nicht zu nah oder zu weit setzen. Ich habe das hier auf Deutsch gefunden:

https://www.huettemann.de/lagerkatalog/download/osb4_belastung.pdf

Ich wuerde immer mit einem margin zur Sicherheit rechnen, vielleicht 20%. Eine Schraube haelt dann also 0.8x70kg = 56kg. Wenn du die Distanzen beachtest und dir das Gewicht deines Schrankes ausrechnest und auf entsprechend viele Schrauben verteilst, solltest du safe sein.

Ich gehe natuerlich davon aus, das die Installationsebene von Wolf Haus fachgerecht konstruiert wurde.

You know what, I'm gonna say it:that was a pretty good use of that template.

Let's not forget that Ubuntu 18.04 has reached its end of life stage in what, April 2023? Pretty much everyone has been dropping support for Ubuntu 18.04 by now, even more impactful dev packages like CMake.

I believe it doesn't really matter much whether you want to protect the environment from vibrations of the machine vs. protecting the machine from vibrations of the environment - in both cases, decoupling the systems is what you want to achieve.

Eventually, you want to build a TMD: https://en.m.wikipedia.org/wiki/Tuned_mass_damper

I personally had to deal with the case of a large format CNC machine transferring stepper motor vibrations into an adjacent office via the wall-mounted brackets it was sitting on. People started to complain shortly after installation since the noise was very audible in the otherwise quiet working environment.

The solution involved placing the machine on a plate mounted via rubber decouplers (see https://www.dayco.com/en/product/decouplers) which in turn was mounted to a shop-built TMD using a rubber core sandwiched between two foam plates. The rubber core works as both mass and absorbs additional vibrations. It was built following a paper, but unfortunately, that was around 7 years ago and I'm not sure I'll be able to dig the publication out again.

You can in fact simulate the TMD and do the tuning (see for example https://www.mathworks.com/help/simscape/ug/mass-spring-damper-in-simulink-and-simscape.html , though dedicated software packages also exist) but in all honesty, that will probably be overkill for your case.

Having your NAS sit on a 1/2" board of baltic birch plywood resting on a foam sandwich is probably going to do the trick in your case. You can easily create such a sandwich using foam, a rubber mat and some spray glue. Different foam densities will give different results and yield different "tunings" - you may have to play around with this a bit. I could imagine you'll most likely even be able to skip the second decoupling step (rubber feet/decouplers), in the aforementioned case the second decoupling allowed for another set of frequencies to be dampened (via a different overall rubber hardness) but also brought overall amplitude down.

Don't use super soft foam, as this will yield a wobbly base, something you probably want to avoid for your NAS. Also, make sure not to attach the base board to anything else apart from the foam, or you'll transmit vibrations again. If you don't like the appearance of the foam, you can build a small fence around it that goes up to the top of the base plate.

All that being said, there are also ready-made solutions like speaker dampening feet available: https://www.amazon.com/Tertullus-Speaker-Isolation-Feet-Anti-Vibration/dp/B09QC2L7N3

Most of them are made to decouple subwoofers, so they might fit into the frequency spectrum you specified. Those couls certainly be an affordable and rather quick way to solve the problem.
