Judging by the paraphernalia, this is what happens after a Finnish amateur radio operator retires and suddenly has way too much free time.

There are a few members in my amateur radio club that have a (~200) collection of CW keys. Bugs, paddles, straight keys, etc. Some very obscure ones (only one or two made), some old ones, strange designs, etc. They'll occasionally bring one to a club meeting and pass it around for people to examine and try.

Last commit to master was over two years ago, has mosh been replaced by something else or is the project just "complete"?

>This is a fairly common fear for people considering a new EV: “Won’t the battery need to be replaced after a few years?”. And I think it’s even more prominent in the second-hand market: “Oh, I’d never buy a second-hand battery!”.

I will admit that both of these are nagging on me. I fully intend for my next car to be an EV, but if I was buying today, this would be a factor. I drive a 2013 Camry (that I got used) that shows no signs of slowing down. I hope to drive it for at least a few more years. If the car is still reliable when it's time to send a kid in it to college, that's probably when I'll start looking for something new. And you can show me studies all day long, but my irrational brain is just worried that I won't be able to get 15+ years out of an EV because there just aren't that many 15 year old EVs driving around today.

Don't forget that internal combustions engines lose power and efficiency over their lifetimes. Bearings, piston rings and other components wear, injectors and valves get dirty, surfaces develop varnish, etc. My last ICE car started needing a quart of oil every few months and that was with very good maintenance and not being driven hard.

I've been curious about how the degradation compares to EVs. I'm aware it's different kind of wear and that there's different ways to mitigate and repair EVs vs ICE, but they both have their own lifetimes and loss of performance.

Have you heard of Heavens Gate? [https://en.m.wikipedia.org/wiki/Heaven%27s_Gate_(religious_g...].

There are at least a dozen I can think of, including the ‘drink the koolaid’ Jonestown massacre.

People be crazy, yo.

Just a note that the Heaven's Gate website is still up. It's a wonderful snapshot of 90s web design. https://www.heavensgate.com/

The refusal to support IPv6 is embarrassing at this point
geoffeg · 20 days ago
I thought a recent downtime was contributed to rolling out the initial prep for IPv6 support.

Got to love it when a Citation whose pilot is to arrogant to radio and a crop duster that doesn’t have any instruments to speak of are both in the pattern.

There have been many times I just decided to come back to the airport a bit later. Or circle well above the airport and watch the chaos below.

Fascinating. Are there instruments that show you in realtime 3d airspaces you can enter and not?
geoffeg · 24 days ago
Most aircraft have a GPS on the panel that can show you the airspace around you and along your flight path, but it's not a required instrument. It's more of a 2D depiction of the airspaces, but there are three dimensional depictions on them. There's also apps like ForeFlight and Garmin Pilot that you can run on a tablet or phone.

Before those electronic methods became ubiquitous pilots used paper charts and references and used ground references, pilotage and navigation aids to determine their position on that paper map. For instance, here's the complex airspace around the aircraft owner's home airport. https://skyvector.com/?ll=33.897663018511054,-117.6024627647...

I'm leaning towards it being some extremely cheeky DCS/flightsim nerd because of the shortness and randomness of the flights.

It's not so easy to land a plane in real life, even if you have a lot of flightsim experience. It is definitely possible and there are people who have done it, but I don't think it's the norm. A lot of flying, especially landing, involves sensory inputs. Additionally, replacing the battery in that Cessna probably requires taking the cowling off. Not properly securing the battery or cowling may result in a bad time if something comes loose. Once again, doable, but you can do as quickly as you can with a car.

> I know literally nothing about flying. How does this work? Wouldn't the air traffic controllers see it on radar and try to radio it then call in the military (I've probably watched too many movies.)? Always blows my mind when I hear this kind of stuff in this day and age.

If you takeoff from an uncontrolled airport and stay clear of controlled and restricted airspace you don't have to say a single thing on any radio and no one will care about you. The controllers would see the blip on their radars but there's no requirements to check in with them (although it's generally a good idea) so they'll mostly keep other aircraft who they are talking to away from you.

Now, if you do fly into controlled airspace near an airport with a tower without talking to anyone, things will change. A slight excursion into the controlled airspace for a short time may go unnoticed, but the more blatant and prolonged the deviation, the larger the response will be. Fly into LAX's airspace and get in the way of their flights and you'll eventually get a visit from some friendly fighter jets. (There are some exceptions. For instance, there's a few narrow corridors through LAX's airspace that don't require talking to ATC. One of those corridors even goes directly over LAX's runways at a few thousand feet.)

It depends on the airport! Some smaller airports (like Corona Municipal Airport where the story is based) - are untowered, meaning that there's no central ATC to chat with when taking off/landing - everyone announces what they're doing as they're doing it and there's a traffic pattern/flow that everyone follows to ensure there's no conflicts - it works surprisingly well.

In the US, you can get shockingly very far without having to chat with ATC.

> everyone announces what they're doing

Well, most people. :)

There's no "requirement" that pilots announce their intentions on the common frequency at uncontrolled airports, some aircraft may not even have radios.
