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…
3 years of security updates is unfortunately very little…
Statistically speaking: no.
Not only if some one complains… Just mentioning the OS which must not be named summons all this guys.
I use arch btw.
The planet itself will survive this easily, the inhabitants on the other hand…
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.
Ctrl-A + Enter once got me an extra work at school, because the shitty PC froze for 20 mins…
Yeah, aluminium foil as cover does sparking wonders in that regard!
Although in this case, it was the EU who wanted to put a backdoor in every encrypted messenger… Thank god it looks like as if it won’t happen!
It’s “ich_iel” on feddit.de
That’s exactly why testing is needed. You can calculate a ton of things but you only know through testing, when and where things fail. Then you iterate and test again.
They get eliminated at first sight!
$ 50
Do you call this fifty dollars, or dollar fifty?
Lots of stuff is written differently, than it is spoken. In case of the date it is weird, not to go from biggest to smallest or vice versa. I guess you are used to it now, but for me it would be the same as putting seconds before minutes or inches before feet.
Am i stupid or is there an example of an ascii image somewhere?
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:
use info on own risk
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.
With speeds at around 10% of c, I should use the formula considering the relativistic doppler effect… However, i wont. Thanks.)

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