Yes, every terrorist in the history of mankind consumed DHMO! Ban this stuff immediately! _/s

Totally agree! Also ppl like to bash on elderly persons. Statistically speaking you are most likely to be hit by a young or middle aged man.

Yep, was thinking the same. And all the other brands of fitness devices…

Glad you are doing better then!

I never wish bad for someone. However, I would wish for you, that you experience for some time, what a depression feels like.

You then would never write stuff like this.

And then they threw out windows 11 in what felt like 2 months from announcement to shipping

Do bipolar bears also exist?

That’s true.

APP = short for application, little programms you can install on your smartphone

FOSS = abbreviation for ‘free open source software’

Hope i could help! If you have further questions, don’t hesitate to ask! Cheers!

Bubble sort. It’s the only one I really understand and know how to implement.

/s to be sure

Wow, did you just really confess as an child porn distributor/consumer? Who else would need such an communication alternative?

Jup, so many accounts I’ve already blocked in my app…

I see so many ad posts on lemmy now… They have to do something about it. This one is particular bad tho…

Not only if some one complains… Just mentioning the OS which must not be named summons all this guys.

I use arch btw.

To add further more: often also 810 or 820 numbers exist, where a phone call might have a toll up to 10 or 20 cents per minute respectively. With 900 numbers you usually dont know, how expensive they are, when only looking at the number.

It’s “ich_iel” on feddit.de

They get eliminated at first sight!

Are you sure about that? From m/s to km/h you multiply by 3600 (for the time) and divide by 1000 (for the distance) which leads to a factor of 3.6.

Personally i always remember 25 m/s = 90 km/h = 56 mph because of the somewhat round numbers.

Sooooo, wavelengths (λ) become longer when something moves away (redshift) and become shorter when something moves towards you (blueshift).

For a red flag (λ0=610nm) to become a green flag (λ1=549nm), it has to move towards you quite fast. But how fast is ‘quite fast’?

Using the formula

flag_velocity / speed of light © = difference in wavelengths / starting wavelength

we get

flag_velocity = (610-549) / 610 * c = 61 / 610 * c = 1/10 * c

This means: the flag has to move with about c/10 = 30 000 000 m/s = 108 000 000 km/h = 67 108 100 mph. Yeah, that’s quite fast.

(Disclaimer:

1. use info on own risk

2. values for λ were chosen in a way to make calculations easy. There is no info on what shade of red or green the flag is. The final result will be about the same.

3. With speeds at around 10% of c, I should use the formula considering the relativistic doppler effect… However, i wont. Thanks.)
