This is a pretty narrow take on aviation safety. A heavier airplane has a higher stall speed, more energy for the brakes to dissipate, longer takeoff/landing distances, a worse climb rate… I’ll happily sacrifice maneuvering speed for better takeoff/landing/climb performance.

Again, just nitpicking, but if you have the right approach speed, and not doing a super short field landing, you need very little wheel brake if any. ;)

Maneuvering speed is Va which is about max deflection on a single control surface, I think you're thinking of Vno if you're referring to turbulence

Indeed I was thinking of Vno. I just had a brain fart when I said manoeuvering speed. I meant to say maximum structural cruising speed.

> the safe manoeuverable speed increases with weight

The reason this is true is because at a higher weight, you'll stall at max deflection before you can put enough stress on the airframe to be a problem. That is to say, at a given speed a heavier airplane will fall out of the air [hyperbole, it will merely stall - significantly reduced lift] before it can rip the wings/elevator off [hyperbole - damage the airframe]. That makes it questionable whether heavier is safer - just changes the failure mode.

Turbulence, especially generated by thunderstorms, or close to it.

Time to apply the best analogy I've ever heard.

> "Measuring software productivity by lines of code is like measuring progress on an airplane by how much it weighs." -- Bill Gates

Do we reward the employee who has added the most weight? Do we celebrate when the AI has added a lot of weight?

At first, it seems like, no, we shouldn't, but actually, it depends. If a person or AI is adding a lot of weight, but it is really important weight, like the engines or the main structure of the plane, then yeah, even though it adds a lot of weight, it's still doing genuinely impressive work. A heavy airplane is more impressive than a light weight one (usually).

I just can’t resist myself when airplanes come up in discussion.

I completely understand your analogy and you are right. However just to nitpick, it is actually super important to have a weight on the airplane at the right place. You have to make sure that your aeroplane does not become tail heavy or it is not recoverable from a stall. Also a heavier aeroplane, within its gross weight, is actually safer as the safe manoeuverable speed increases with weight.

The hard reality is that there is no PAYING market for such a device, because when it comes to the point-of-sale, most people still choose the normal-size device with better screen/battery/camera.

This is equivalent to something I called the "QWERTY paradox" more than a decade ago:

Back when the Smartphone market exploded, people disliked typing on a touchscreen and repeatedly stated that they want a device with a physical keyboard.

There was plenty of evidence, surveys, market studies, trend predictions, devices for these "Messaging-centric" use-cases were always part of this market-demand roster.

But whenever someone answered the call and built a Smartphone with QWERTY keyboard, the product failed commercially, simply because also to people claiming they want such a phone, at the point of sale they were less attractive than their slimmer, lighter, all-screen counterparts.

Every major vendor went through this cycle of learning that lesson, usually with an iteration like "it needs to be a premium high-spec device" --> (didn't sell) --> "ah, it should be mass-market" --> (also didn't sell).

You can find this journey for every vendor. Samsung, LG, HTC, Motorola, Sony.

The same lessons were already learnt for small-screen devices: There was a "Mini" series of Samsung Galaxy, LG G-series, HTC One, Sony Xperia. It didn't sell, the numbers showed that it didn't attract additional customers, at best it only fragmented the existing customer-base.

Blackberries? Granted, they failed but for a completely different reason.

Whoa, love this. Do you have any recommended resources if I wanted to try this out? Any comments about FreeSWITCH vs Asterisk, or BulkVS vs Signalwire for a simple setup like this?
subhro · 7 months ago
Freeswitch is more complicated and has a steeper learning curve, but you can pair it with FusionPBX and it will make things a lot more palatable. Asterix is the grand daddy of this stuff. The community is stronger for Asterix. Freeswitch is pretty much infinitely customizable.

SignalWire is the primary sponsor of Freeswitch but is mainly geared towards HUGE installations. BulkVS is cheaper and better in my opinion. You can also look at AnveoDirect, which is more raw than BulkVS, but you can become really really fancy with it. Like, call center fancy.

Keep in mind, the main use case is allowing kids to call their friends and family and no one else.

VoIP nerds out there, is there any simple PFSense equivalent for VoIP that would allow you to DIY this? Basically restrict inbound and outbound calls to a whitelist?

subhro · 7 months ago
Yes, get a trunk from someone like BulkVS, SignalWire and run your own freeswitch or asterix. You can set up arbitrary “allowed” lists. Hell you can even get fancy with lookups and decide on the fly to allow a call or not.

There are other comments about providers, but my way is way cheaper and you can run you EPBAX on a pi or even get a pre made VM from Azure, Amazon, etc.

Damn I hate paying rent.
