In this thread. A bunch of people who've never had to use the prior remote internet solutions that existed prior to Starlink. For a good chunk of the world, Starlink is actually game changing.

I spent the better part of the last decade working in remote locations, including the high arctic and and rural indigenous communities. Starlink is both fast and affordable compared to the prior solutions. Hell, I even personally worked on hundred million dollar fibre optic line projects, that were hundreds of millions over budget, trying to get these communities connected. Starlink is hands down the better choice, unless you really wanted to put your data centre in Fort Good Hope for some unknown reason.

If Elon wasn't attached to this project, I'd bet the ratio of negative comments would be lower.

It's okay. Lemmy isn't a wiki. Content is organized temporally. Imagine these conversations as bar conversations (just because one group had a conversation one night, doesn't mean another group can't repeat it the next). If you are annoyed that the algo keeps giving you the same stuff, sort by All and New Comments and you'll find niche communities to subscribe to.

Just wanted to say: I hope you're enjoying the project. Implementing something like you've done has always been a dream down-time programming project for me, but I've never had the time. I grew up with Impulse Tracker and similar in the MSDOS era, and later took a geophysics degree (which is much about waveforms and signal analysis when you get down to it -- what is a seismic wave if not audio...). And I've always just wanted to play with programmable audio and effects. So you're living my alter-ego's life :)

I'm not going to make any feature requests. I'm too busy with work to even poke your software. I just wanted to throw some kudos towards you for doing something cool :)

Utility corridor. Sometimes a "Right of Way".

Depending on where you live, "hydro lines" or "transmission lines" or similar.

It'll also largely depend on jurisdiction.

Really, I'd ask for a lawyer and have the lawyer advise you here. A misinterpretation and suddenly you're violently resisting arrest or something.

Making amateur rockets and pipe bombs are basically identical -- for a rocket, one end of the pipe is open. There's a vibrant amateur rockets community nevertheless.

This would be really dependant on circumstances, no?

I have that as my cell phone notification. It's amazing.

You have python. You import antigravity. The princess flies off into space. You monkey patch the princess so she has wings.

Ah, you're probably right.

There's physics reasons that 5g is theoretically faster, while also having lower range. It's related to the frequency used. All other things being equal, higher frequency radio waves attenuate faster in any given medium than lower frequency waves. (Their range would effectively be identical in a vacuum.) But, the total number of waves you can transmit in any given period is inversely proportional to attenuation.

As you approach a bitrate that is equal to the frequency, you start to run up against the limits of physics in terms of how much information you can transmit. Choosing a frequency arbitrary to illustrate: 900 MHz. At 900MHz, there are 900 million waves going out per second. In some perfect universe, you could turn the signal on/off up to 900 million times per second, giving you a theoretical bitrate of 900Mbit, or 112MB/s. In reality, you never approach this limit, due to error correction and a bunch of other things, so you might get a tenth of that speed as your practical maximum from an engineering perspective. So maybe 10MB/s. There are other tricks you can do, like MIMO on multiple adjacent frequencies, but that is a digression.

But if you go from 900 MHz to 2.4GHz, you automatically gain a reprieve from the physics, allowing you to potentially gain 2.7x the speed. Amazing! Only, now the signal is absorbed by materials 2.7x faster, and has trouble penetrating through walls as well and such. Yikes!

So you have a tradeoff. 4G is a lower frequency than 5G. 5G makes more sense in very dense open environments: stadiums, concerts, busy outdoor markets, etc. where you need a lot of bandwidth in a small area without a lot of obstacles. 4G will penetrate the walls of your house better, at lower theoretical top speeds. Phones can and should switch to whatever is optimal for the environment you're in.

We're near the limit of physics on these things and I don't expect things will evolve a lot more from here.
