I'd be much more likely to buy this if it were a local application. At large companies, it's not uncommon to have a security policy that forbids using 3rd party SaaS apps that haven't been formally blessed by IT. Getting that

Preview.app is very underrated. It feels like a huge omission that other platforms don't have something similar built in. And if you need more editing features than Preview.app (which is already very powerful), PDF Expert [1] is my go-

The person in that article was using SPOT, not a PLB. Actual PLBs ( not SPOT) have a backup strategy in the event the GPS signal is obscured by mountains. If the device can't get a reliable GPS fix, the satellites will resort to measu

Keep in mind $100 is the retail price, not the wholesale price (which is what's plotted on the above graph). I do not know what the current wholesale price is for a generic epi-pen. My point is merely that the price is trending back do

There are generic epi-pens available now. With GoodRx (no insurance), retail price is now about $100 - and with insurance, it's sometimes closer to $0.

I use the Pomodoro Technique. Given that it divides the day into 15 minute work blocks, it might work well for you too. https://en.wikipedia.org/wiki/Pomodoro_Technique It's worth reading through the original Pomo

If by "radio comms", you mean playing a pre-recorded emergency message on a loop telling everyone to get out of the way. It can't visually identify non-ADS-B traffic (and I'm not even sure yet if it will avoid ADS-B equi

On the other hand, if you're going to actually do DIY work on your house's wiring, it would be prudent to at least have some familiarity with the NEC. Since we're in a democracy, every election involves everyday citizens adju

The medical intercom jack is often in the middle of the cabin (on equipped aircraft). Flight attendants can plug in an aviation headset with a very, very long cord, and the pilots patch it into one of the radios in the cockpit. This allow

Indeed. One of the more useful perks from an ACM membership. I was sad to see it go. Thankfully there's a good chance you can still get access to O'Reilly through your local library's digital collection.

No, as you mentioned, 406link is a commercial hack that detects a PLB's "test" message and uses that to trigger a pre-programmed "I'm ok" message. But that's not what I'm referring to. By one-way comm

Depends on where in the world you are. For the US, it's on a state-by-state basis but rescue is usually free as long as it's a true emergency and you weren't blatantly reckless to begin with. For other parts of the world, you

Having used these types of satellite messenger devices, it can take 1-2 minutes just to send an SMS. Loading graphical maps is out of the question, unless you use a different satellite network.

by tjohns 4y ago
It's worth noting that you can use a PLB (which runs on the COSPAS-SARSAT network) to summon help for free. No subscription required. On the other hand, the devices themselves cost $300 and aren't usable for anything else outside

Even in a national park, it will take time to respond to a satellite call. Contrary to popular belief, search and rescue doesn't always send a helicopter. It's still common to send a ranger on foot and help walk somebody out on th

InReach offers it as a optional paid add-on ($30) when you sign up for an account. While not always true internationally, at least in the US most jurisdictions won't charge for rescue as long unless you weren't careless and reck

The challenge here is that these satellite networks get a significant amount of their operating revenue from charging for emergency-only communication. Unlike 911, the satellite company itself is also responsible for hiring the dispatchers

The numbers I gave were national averages for the US. Of course those numbers will vary by location. That said... you'd be surprised how many flights out of the small GA airports in big cities aren't personal flights. Air ambulanc

Quick napkin math here... The estimate is that about 65% of general aviation traffic is related to "business and public services". [1][2] The other 35% is personal in nature. From that, about 22% is flight instruction for new pilo

And to be clear, "knocking" means engine detonation, which very quickly leads to catastrophic engine failure. Which is something that you don't want while in flight. Until now, the only alternative was to fly a turbine-powe
