The radar you're talking about is a pulse-doppler radar. It doesn't see things the same way your eyes (or a synthetic-aperture radar for example) do and it's not down to filters. A P-D radar observes and measures the Doppler effect which only occurs when the object is moving and determines the contact's velocity, heading and altitude based on that. A jet flying vertically at 0 GS would probably be detectable, although this would be difficult since, as you said, it's not moving directly towards or away from the radar.

Re-rendering 4k videos (or of any other quality fwiw) with ads included would probably incur more electricity costs than they could ever make through the ads. TV could afford to do this since they transmit the same program and the same ads to everyone. Youtube targets them per user, so they'd need to render the same video, in high quality, every time any user clicks on it.

when are they gonna learn that any client-side restriction or hindrance can and will be defeated? sleep(5000) is kinda like them throwing a fit, not actually trying to punish anyone. obviously we'll find a way to avoid waiting the 5s, do they think we'll just give up?

what is it with chinese-made games and extremely invasive anticheats

hijacking update channels is a possibility but as the other guy said very unlikely

I don't think it's paranoid to not want any intermediary to know what you're talking about, even if all you're talking about is innocuous things like groceries.

Besides, they don't have to "waste time" on anything. They've got computers to collect it all.

Of course, like you said, Signal or Matrix are potential solutions for that, but you still need to get both sides to agree on using them. SMS have the advantage that everyone has a phone number and can thus use them. Upgrading to RCS will secure this insecure-yet-very-popular medium.

Is there zero risk or do you think there is zero risk? Text messages can absolutely be intercepted by your service provider

Yeah, he learned it from the Russians

[–] [email protected] 3 points 10 months ago

Because as we all know Chinese companies never collect people's data

Why not both? Digital is obviously better but analog is painfully simple hence it'll probably be the medium used for transmitting emergency alerts

Stop trusting your messaging platform and use this other messaging platform! Matrix can be less secure than Signal if used improperly

yeah like hell i will. remember to protect yourself with something like fawkes when posting pictures of your face online, fellas.

 

We all know the marshaller signals. Go left, go right, stop, death threat, etc.

There is, however, one that appears in official docs, but never in discussions or at the airport (at least I've never had a marshaller show this to me) – the "dispatch aircraft" symbol:

Marshaller saluting with his right hand, holding wands in his lowered left hand

Does anyone know when this is used, if at all? The definition ("Perform a standard salute with right hand and/or wand to dispatch the aircraft. Maintain eye contact with flight crew until aircraft has begun to taxi.") suggests that it's supposed to be used after you obtain taxi clearance but before you start to move.

That said, the marshaller has never been present when I was getting ready to taxi. I always just called tower or delivery to get startup and taxi clearances, switched on the taxi lights and went on my merry way. So, what's the reason for this hand signal's existence? And how would the marshaller know when to dispatch the aircraft since (I assume) they aren't listening in on radio? Is it only used in commercial or military aviation? I know it's a standard thing on aircraft carriers to confirm the pilot is ready for takeoff, but this signal is featured in ICAO docs, not US Navy procedures. Has anyone here been saluted by a marshaller? Would love to hear your answers.

Install

Hi,

This is just a little helper script which adds buttons to posts and comments on any Lemmy instance except your own which lead to a search page in your home instance allowing you to quickly interact with content.

For now this is just a bunch of buttons, but ideally it'd be a fully-featured script that presents you with a proper text field for commenting/replying and buttons for voting. This is just the initial release and I'll be working to make the script better and save even more time while slacking off on Lemmy :P

Usage

Click the big 'Install' button above, then approve the script on the page displayed by your userscript manager. I've tested it on Violentmonkey and Tampermonkey with Firefox.

After installing, go to any Lemmy instance and enter your home instance's domain into the prompt (just the domain, like lemmy.world or sh.itjust.works and nothing else). You can change this domain later by clicking on your manager's icon, then on "Change home instance" below the script's name.

From now on you'll see blue buttons ("[ comment on own instance instead ]" on posts and "[ C ]" on comments) outside your specified home instance. Click on any to go to a search page on your own instance, then click the link icon if you're interacting with a comment or post title if with a post, then reply or vote on content as you desire.

This is the first release, so might be prone to breaking and isn't very beautiful yet. Please report any issues and send suggestions via DM or in the comments below.

Thanks and happy using.

 

On Reddit I frequently heard stories from either newly-passed or newly-failed private pilots outlining the entire process and seeking advice. So I started wondering - how difficult is it to pass the PPL check in the US? I heard that there is a long oral questions part where the examiner quizzes you on the theoretical parts before you even start to brief the flight, much less get in the cockpit. Are there no written exams there, just these questions? Or is it both? If both, why is this part so long (heard it can go on for over an hour)? Do you need to know what every FAR regulates? I frequently see Americans referencing FARs alongside their numbers as if they had an index in their head lol

Here in EASA land one of my friends told me that the check is "hard to fail if you paid attention" and, while stressful, yeah, the examiner did not try to trip me up with questions nor did he ask me to perform maneuvers I haven't practiced well. It felt like just another solo XC flight, a couple touch-and-gos at the destination airport including without flaps and without engine power, then on the way back a few stalls, deep turns, some rudimentary instrument flying and that was it. Haven't heard of anyone who failed the thing so far.

So, how's the situation where you guys are? What's the pass rate? Do you know someone who failed (or maybe even you yourself had failed)? Would love to hear from you all!

Hi everyone, I just joined here and wanted to subscribe to a few communities off-lemmyfly like [email protected] but can't find a way to do it. When I search for [email protected] I get no results and even when going directly to https://lemmyfly.org/c/[email protected] I get hit with a 404. Am I doing something wrong or is it just not possible to do it?
