Almost certainly not. The usual challenges here are: 1. The codec is computationally expensive (at least by embedded-device standards). Often this is handled by a dedicated ASIC. 2. The waveform needed for DMR (TDMA 4-FSK) or D-STAR (narrow

You absolutely can buy AEDs for home use, and if you're high-risk it might even be a good idea. The only reason it's not recommended more widely is cost (they also need regular maintenance) and likelihood of actually needing it

How does seat-miles matter here at all? That's not a normal metric used in this field. Using seat-miles leads to some very strange conclusions. Consider cargo aircraft with zero seats, or a helicopter that mostly hovers in place all da

Aircraft fly higher, which means they pick up ground radio signals from much further away - both good (ATC communication, ground-based navigation beacons) and bad (intentional jamming). On the ground, the radio horizon is about 20-40 miles.

Cellular compression will not play nicely with analog modems. (Or any lossy compression, really - this is why you have to use lossless G.711 to have any hope of this working on VoIP.) Back in the days of 2G cellular, GSM had an option to ha

On older systems, scrolling on the trackpad would emulate mouse scroll wheel events - scrolling my one (or more) lines per increment. This made sense with scroll wheels, because they moved in discrete (large) clicks. The problem isn&#x2

Not if the power goes out. Unlike landlines (which are required to have generators at the central office), cell towers are only required to have a battery backup that lasts a couple hours. When we had the rolling blackouts in the bay area a

I don't think many people will argue that running from the police is something we want to legitimize. It is also is never going to end well. The police have orders of magnitude more resources and will eventually catch you. (And meanw

Also, safety. Being able to floor it during an emergency can sometimes get you out of an impending crash - if the situation is right, and your reaction time is quick enough.

No, it's definitely illegal, at least by the letter of the law. But as long as you're only going a few miles over the speed limit for a few moments, nobody's going to write you a ticket for it. One of many situations where th

Every aircraft has some missing screws. Literally every aircraft. That's why there's so many of them. Some of them matter, and the pilots keep a close eye on those during the preflight checks. Others, matter less so. (A single

No aircraft would ever fly then. You'd be surprised how much equipment on every single flight is inoperative or scheduled for deferred maintenance. There's an engineered threshold at which an aircraft is deemed not airworthy. On a

This is not a 737 Max 9, it's an older 737 - technically a Boeing C40, which is a military variant derived from the older 737NG line. These have historically been extremely reliable. Aircraft frequently have to be grounded for maintena

At least in the ham radio community, experience is that digital radio sounds better further, but at the extreme ends of signal reception the digital signal becomes completely unusable before an analog signal becomes unintelligible. See: ht

You don't really need more security, because if a pilot gets an ATC instruction that doesn't make sense, they're going to question it. Pilots aren't following instructions blindly, everything is mentally cross-checked ag

Look at it this way: Your body secrets a certain amount of hunger hormones. The GLP-1 drugs act in a way that blocks those hormones. (I'm greatly simplifying here.) In response, your body secretes more hormones, so you take more GLP-1

The thing to keep in mind with Ozempic (and other GLP-1 agonists) is that it's essentially a forever drug. The data is clear that when you stop taking it, you will gain the weight back, rapidly, with almost near certainty. For folks
