Earlier quoted context omitted.

Your ground speed plot hovering around 500 mph would be ~800 km/h which is oddly slow for an airliner, unless you were facing strong headwinds the entire way. The nautical mile is historically the common unit for marine and air navigation.

Clarification: a knot is one nautical mile per hour.

Isn't it 1.15mph?

I'm an Alaska (relatively) frequent flyer. That airline offers a free "messaging" plan, that lets you send and receive messages on apps like iMessage, Facebook Messenger and Whatsapp. Though, it somehow prevents images/attachments from coming through on those platforms. I've always wondered how this is implemented technically, and if it might be possible to setup some kind of protocol/wrapper to send data that looks…

I used to work at WhatsApp (until the end of 2019) on many things, including special pricing (aka zero rating); we did not work with airlines, and would not have participated in a project where messages and attachments where treated differently.

That said, technically there's two pretty easy ways to do it for WhatsApp traffic, and then there's the way I suspect they're doing it...

a) chat runs on different ips than attachments; always has, most likely always will (other than some transitional HAProxy at the old hosting when nearly everything had been moved to the new hosting).

b) WA chat is not HTTPS (or even TLS) and attachments are. Chat also cycles between different ports, so you could just block port 443 and be good.

c) I actually suspect, based on poking around a little that it's mostly just killing connections that use a lot of data. Maybe in combination with some other things. Being on a plane doesn't really put me in a debug the network kind of mood, so I never got to the bottom of it, but I'd regularly be able to make short connections to my home network while on the messaging plan, at least when this stuff was new. OTOH, I think I recall being able to connect through the WA VPN while on a plane on the messaging plan, but that was when we had a publicly available, but not publicly linked list of IP addresses on our website; I have no doubt that DPI vendors had that list.

Hi fellow Alaska frequent flier. So about that! There's this iOS app called Flightly that does a brilliant little hack where the app updates itself in (almost) real time on the "free messaging" plan. The way it works (according to a friend) is that their servers send your phone a push notification every couple of minutes from take-off until landing, containing some serialized info such as lat,long,alt,eta,etc. And th…

Really hoping someone implements this, it’s the funniest project idea I’ve seen in a while :)

Fun story =) Anyone else freaked out by that "time" format though? Seems like a strange choice, would have expected something more standard like ISO 8601 with timezone offset. "time": "Sun Sep 24 22:02:19 2023"

It looks like the default formatting used by `ctime`. Could be a clue about the underlying backend.

If you travel lite with clothes in a book bag(wash clothes if extended stay)… I don't see why anyone would fly United, Southwest, American Airlines, etc VS.the budget Airlines like Spirit.

Maybe if you have points with those airlines… Otherwise, save hundreds of dollars using budget airlines which the planes are newer in my experience, and never had a bad experience versus my recent bad experiences with Delta and the others in which I paid a lot more for. Almost all airlines I've had to pay for Internet access, including Spirit so for me, I don't understand why I would fly all the more expensive airlines versus using Spirit.

There's a lot of negative marketing out there about Spirit… After my 10 positive flights experiences in the last six months with them I don't believe the hype.

How does that fly (pun intended) with regards to net neutrality? Where I live, some mobile operators gave you "unlimited streaming" in their data plan, but only for certain popular services (spotify, youtube, netflix basically). Since this would make it harder for others to disrupt the big ones, it was quickly forbidden.

Is net neutrality even law anymore? T-Mobile has had Binge on for a long time, which zero-rates certain video streaming services. And part of that was even under the old net neutrality laws.

No, but the now Democratic majority at the FCC is currently actively trying to bring it back.

You could try iodine, which is an IP-over-DNS tunnel. This should work unless the gateway has very restrictive rules on where DNS traffic can go.

Reminds me of the time I dumped CANbus data off a Yamaha R1 bike, made sense of the data, and displayed it on a bunch of charts. Interesting data like Accelerator Handle position, you can figure out how much a rider is really cranking it, and how aggressive they are riding.

... Which is precisely the data those data loggers you plug in from insurance companies track to adjust/refine your rates .....

Honestly, it seems pretty fair to me. If I'm a careful, occasional driver, and the insurance company otherwise has no way of knowing that, then they have to bill me like I'm commuting every day in stop and go traffic, distracted by podcasts and who knows what else.

There will probably always be a "premium" market for no-questions-asked insurance, but if the company can give me a break on my rate based on my driving behaviours correlating to a lower incident likelihood, I'll happily take that break. Even better if such measures correspond to drivers across the board adjusting their habits now that it hits them directly in the wallet.

Binge On doesn't fall under strict net neutrality, but they are at least publicly open to all lawful and licensed content audio/video providers, and the technical requirements are not very high. I don't know what the actual onboarding process is like, but they've got a lot of providers signed up...
