My feet are certainly not a feet long. More like 25 cm or so. But as another commenter already said, I can measure ~175 cm using my arm's reach easily, matchboxes are standardised as 5 cm long, the width of my palm is about 8 cm, distance from my fingertips to my elbow is around 50 cm and the distance from ground to approx. my navel is 1 meter.

Plenty of ways to get an approximate metric measurements without a ruler or measuring tape.

And it's much easier to convert from cm or mm to m (or vice versa) than to convert between ft and inch or ft and 1/8 of an inch or whatever weird measuring standards the US-ians use.

Our hearing has no hard limit in low frequencies--sensitivity falls off at the extreme, but it doesn't mean you can't hear sounds below 20Hz. That 20 Hz limit is often quoted simply because the tests that were done in the past didn't measure lower. In reality, most people can hear 15 Hz and lower, just the threshold of hearing goes up. That's ignoring tactile effects of these frequencies, which adds a whole new dimension of sensing ULF.

Many movies have a crapton of LFE below 20Hz (for example Blackhawk Down has a scene with single-digit ULF effects), though you generally get it only on blu-ray or DVD releases, streaming services tend to have a neutered sound mix. Today's subwoofer tech has advanced to a point that even commercially available subwoofers can do 20 Hz and lower; bespoke sealed cab systems with 8 or more 18" or 21" drivers and a dozen kW of amplification can do single digits at 120+ dB in-room. Head over to avsforum.com for discussion and home cinema system show-offs :)

Why would anyone put these frequencies on a record? Well, sound designers and mixers tend to have very good sound systems, both at work and at home, and are generally very passionate about their work. Same thing as guitarists are very picky about their instruments and pedals, while the average concertgoer or radio listener couldn't make out any difference between a 500€ and a 10000€ guitar, never mind different pickups and overdrive pedals.

The JP movie (and book, too) took a lot of artistic license. Which is understandable; if the T. rex was depicted as having realistic senses, it would have been a quite short movie with a grizzly ending. And realistic velociraptors wouldn't have been as intimidating—they's been small and quite dumb.

What I really wish is that they'd done the vocalisations of T. rex more realistic—the high pitched screaming was not right. Imagine if the first sign of the rex wasn't ripples in the water glass but the barely perceptible sub-20 Hz vocalisations from the distance that grow loud and nauseating as it gets close. Granted, not many sound systems could reproduce it—mine can and it's glorious.

It's amazing how much you can infer from the shape and size of the various features of a bone.

For eyesight, simple physics: bigger is better. That's why we build huge telescopes, they collect more light and have better angular resolution than small ones, and the same goes for eyes. In addition, birds in general have very good eyesight and dinos are very closely related to birds. For T. rex, they also have narrow snouts allowing for excellent binocular vision.

Smell is similar—big nasal cavities allow for big olfactory organs, meaning a lot of receptors that can bind with airborne molecules.

Don't try to convince me that a 12 meters long, 8 tons heavy cassowary with mouth full of >20 cm long teeth and eyes that have better visual acuity than hawks or eagles, being able to see you from 6 km away, while also having excellent sense of smell, is not scary.

Fluffy or not, I wouldn't want to be closer than about 10 km to a hungry Tyrannosaurus.

Who's Amy Winehouse*? I've probably never heard a song from her. I have heard most of Nirvana's songs, even the more obscure ones (how many casual music listeners know Beans?). And it has nothing to do with the artist's gender, or how famous they are. Along Cobain, another very impactful artist for me is Leslie Fish—I bet most people have no idea who she is, but everyone should give a listen to Firestorm🙃

*A rhetoric question.

Hasn't this been the case always? One excavator operator can dig a hole for house foundation way faster than 10 guys with shovels; one truck driver can deliver more cargo than a caravan of horse-drawn carriages; one electronic computer can solve math problems way faster than a room full of humans doing paper-and-pencil calculations; e-mails are faster and can carry way more data than telegraph. AI is just the next step on this path. AI is not the problem, our neoliberal capitalist economic system that seeks unlimited growth of profit is.

Having faced the same situation, here's my 2 cents:

• OMV is the best solution for reusing/upcycling old consumer grade PC hardware. Your storage pool is easily expandable using MergerFS, you don't need 16+ GB of RAM, and you certainly don't need server-grade hardware. But you won't have the bells and whistles the ZFS offers (yes, there is ZFS plugin, but at this point, why not just use TrueNAS?).
• TrueNAS if you intend to build a "serious" storage server with many GB-s of ECC RAM, multi-Gbit networking and all that jazz. And if you have the budget to buy 5 or 6 large HDD-s at once to start out your storage pool with a single vdev using RAIDz1 or RAIDz2 (or buy 2 HDDs for a single mirrored vdev with a whopping 50% of all your current and future storage going to redundancy). As I understand it, ZFS expandability is in the works, but not production-ready yet—which makes ZFS less suitable for ad hoc grow-it-as-you-go storage solution.

In the end, OMV won it out for me, the 10TB motley crew of various HDD-s has served me well and I can expand cheaply when my needs grow.

Plastic recycling was megacorps gaslighting consumers (hate that word) and pushing the blame to us from the very beginning. They don't want to fix the issue.

PNG compresses like nothing else when it comes to graphs, text, UI elements, digital drawings, comics, screenshots from apps etc. And doesn't suffer from "mosquito" artifacts and other .jpg nonsense. It was never meant to be used for photographs and other statistically "noisy" images for which .jpg works much better.

I have an older version of Office (and more importantly, Access) at work which doesn't want to hear anything about .webp. When I need to make a document containing product pictures for a customer, .webp is a huge annoyance and time waste. Luckily the Firefox extension that bans .webp and forces .png or .jpg saves the day.

Transcoding and serving images as .webp as default is fine for saving BW and all that jazz, but when I click "Save image as" I should automagically end up on my disk with the original image format whatever that might be. But since that doesn't seem to be a thing, I'll happily find a way to force the server to serve the original all the time since for me BW is not a problem, but I don't want to waste time converting every image before I can actually use it.

Something-something die as a hero or become the villain.
