I got spurs that jingle

unlike the courier transform, the fourier transform is reversible

Did you accidentally remove the default upvote from your own comment?

rain_worl@lemmy.world on 21 Feb 20:54 collapse

no. purposeful. but yes to your name

I’ve seen other people do this habitually. What’s the reasoning to go out of your way to do this? Just curious.

rain_worl@lemmy.world on 21 Feb 23:39 collapse

dunno, really. here’s my theory:
reddit allows you to “do” that, but it has no effect, other than showing that status. you can see it if you reload the page. lemmy actually lets you do that, thus i feel like i’m “spiting” reddit. more recently, it’s more of a habit.

Fair enough. Small acts of rebellion etc.

To a certain degree a damaged package is the delivery people’s fault, I agree.

But there’s also the people who don’t pack the orders correctly so the packages don’t even withstand standard handling just so they can save packaging material…

I once ordered two mugs from Etsy. It was literally two mugs in a cardboard box. No bubble wrap, no nothing. Arrived in about 8 pieces.

Maybe you just missed the part in the description of the mugs that says “some assembly required.” 🤷🏻‍♂️

ifItWasUpToMe@lemmy.ca on 21 Feb 23:26 collapse

Damn fine print!

I’m a carrier for USPS, I have a guy on my route who often orders Volkswagen parts from all over Europe. One day he got a replacement subframe for one of his VW’s from Estonia and it arrived at our office pretty beat up. When he needed to sign for it he saw the condition and I told him that’s how we received it. The shipper sent it by just sticking the subframe in a box, no padding, no supports, just a cardboard box for a trip around the world. He obviously was upset and had another one sent as a replacement after filing a claim.

The replacement was packaged exactly the same, and luckily only slightly bent on arrival. The old one is still sitting in our office in limbo.

If you’re gonna ship something overseas or across town package that shit properly

Still the best graphical explanation of the Fourier transform. Still wish they just showed this in signals and systems and saved the remaining 3 months of the quarter.

i_love_FFT@jlai.lu on 22 Feb 11:57 collapse

You can also use wavelets to get the middle graph and access the benefit of both spatial and fréquential localization, up to the uncertainty limit!

Yppm@lemy.lol on 21 Feb 23:26 next collapse

Is this how a Fourier transform actually works?

Speculater@lemmy.world on 21 Feb 23:41 collapse

Yep. It translates time spaced frequencies to wavelength based space. So a 1Hz frequency would just have a single peak at 1s.

vaionko@sopuli.xyz on 22 Feb 15:46 collapse

Not necessarily wavelength based, it can be frequency too.

i_love_FFT@jlai.lu on 22 Feb 11:58 next collapse

I love Fourier transforms.

I don’t love courier transforms.

Croquette@sh.itjust.works on 22 Feb 14:59 next collapse

I wish they would have shown me the top picture 15 years ago, it makes so much sense.

DogWater@lemmy.world on 22 Feb 16:05 collapse

But why did I pronounce it courier instead of courier
