speedbird··on Why are banks still getting authentication so wrong?
Very few organisations get international use cases right. Want to load that public transport app for the city you’re spending three months in? Sorry, only available if your phone is tied to the local App Store. Use an international number as your primary contact number? No chance. &etc &etc
speedbird··on Airbnb is in midlife crisis mode
Half the airbnbs I try to book these days turn out to be resellers of un booked hotel rooms. Try to book, get a message from “host” just checking availability… silence for three days then sorry, not free … it’s a deeply flawed experience and Airbnb need to get a lot better at policing their platform
speedbird··on The great displacement is already well underway?
OP, you’re setting yourself up to fail.

Stop being so different and try to match what companies are looking for.

Remote only.

Single letter surname.

This constraint, that constraint, you’re getting the answer you are telling the market to give you.

Yes there are now significant barriers you face: x months not in a relevant role, laid off, 20 years in the industry without a management role.

If you’re pitching yourself against people who have 3-5 years experience, will work 50-60 hour weeks coz early in career and lifestyle unencumbered, it’s not going to go your way.

That means you have to go the extra mile to fit what is wanted.

And yes, that likely means significant drop in salary / attractiveness of role / commute etc.

Maybe there just isn’t the work where you are and you will need to move, maybe your mother too.

Talk to people in the industry you know and trust about this, not HN.

I’ve been in similar situations, currently in a very tech role at 62, but that’s not usual.

Wish you the best

That’s pretty startling to hear. As a child growing up in a london suburb we would disappear for hours to the local park and environs. Playing cricket, other games, or just roaming around. About the only supervision was if the dog came too.

speedbird··on Launch HN: Airhart Aeronautics (YC S22) – A modern personal airplane
On no. 4, it's when things hit the fan and people get overloaded that they revert to basics and don't take in complex information well. Particularly if they don't have regular relevant training/experience. Having the controls move as per system / AP input with the ability to override manually is good, but then how does the envelope control work, does it start ignoring input, or lock up the ability to override the controls, ... ?

What about the scenario where you are in climb out, 50' AGL, and wind rotor off some trees gives you an immediate 90 degree roll (happened to me in a PA38), does the system auto recover that, does the pilot, what happens if the panicking pilot attempts incorrect controls, ...

Not saying all this isn't solvable, but it's complicated and I'm struggling to see how you are going to get a large enough market to deliver all this tech at an affordable price. Force feedback controllers, flying and engine controls all with redundant sensors and actuators, mechanically robust ...

speedbird··on Launch HN: Airhart Aeronautics (YC S22) – A modern personal airplane
I think you’re trying to solve the wrong problem, though with a lot of the right tech.

Basic stick and rudder skills aren’t that hard, save perhaps for crosswind landing/takeoff.

Envelope protection and emergency auto land are good, but I think already done by other companies.

Taking existing controls (stick and throttle) but giving them different names and making them command inputs rather than controls, but ones that vary what that command is subject to the IMPLICIT mode the aircraft believes it’s in (TOGA, land, cruise, taxi etc) are sowing the ground for confusion - look at all the analyses of Airbus incidents due to pilots not understanding what modes the aircraft thinks it’s in due to combination of control and sensors and control law fallbacks due to failures. The idea is sound but pilots lulled into complacency with normally simplified handling get into wild and sometimes fatal rides when things go amiss. Spend time on Mentor Pilot’s excellent channel.

Personally I think one of the biggest improvements to safety would be a decent AoA display and warning system for all aircraft.

Next up a solution to VFR into IMC, with subsequent loss of control or terrain / obstacle impact, which is effectively a use case of envelope protection and emergency autoland.

This tech exists, it’s just not in most of the fleet and not triple redundant.

Finally, rather than trying to make an aircraft more like a car, or only being confident flying your aircraft within a narrow regime, go do some aerobatics and unusual attitude training so you get a feel for how the wing really flies.

speedbird··on Is the move to electric cars running out of power?
Not possible if you like in the sticks and want to live a normal life.

Major metropolis with lots of public transport infrastructure and an Uber only 5 minutes away at 3am, sure.

Personal experience both.

Back in the day, when you could also blag a jump seat ride in the cockpit, nuclear plants used to do tours. Had a fascinating afternoon once in the Wylfa plant in Anglesey that included walking over the top and seeing the refuelling gear.
speedbird··on The unstallable plane that stalled
This +++. Most important parameter is AoA and we only have poor proxy for it in most GA. Nuts
speedbird··on The unstallable plane that stalled
STOL kit and possibly trim setting causes tip stall rather than root.
speedbird··on The unstallable plane that stalled
I’ve got a few hundred hours in the usual pipers and light twin, but I’d say I never really learned about flying, and particularly “flying the wing” until I got into aerobatics and deliberately upsetting the aircraft. It’s priceless learning to go beyond the normal and being comfortable with it.

speedbird··on DIY Wi-Fi thermostat from scratch with ESPHome and Home Assistant
Have to say with my background individual room control and measurement always seemed the nirvana, but it seems like a lot of heating design is moving away from this to more constant input / constant loss with outside temperature curve adjustment. Take a look at heat geeks.

You’ve got quite a complicated system there. Some of the key design parameters are about getting balanced flow (proportional) rather than bang bang controllers so that you optimise the delta flow return and operate the heat source at lowest realistic flow return values for efficiency.

Not convinced. The second reference has a slight Indian accent that isn’t carried over into the generated samples.

Training data bias?

speedbird··on Pulsejet Drone Flies, Could Have Big Impact on Cost of Future Weapons
Forgive my skepticism, but I seem to recall pulse jets have almost no throttle ability (hence the dead stick landing) and pretty poor fuel efficiency (v low compression / pressure ratio).

Then there's the sound and IR signature.

So maybe for a garage workshop cruise missile, not so much for mainstream use ...

speedbird··on Not setting up Find My bricked my MacBook
Similar - 2021 MBP 16". splash of red wine on the keyboard and despite all the usual solutions a few keys don't work. Works fine with external keyboard. Apple Store: we can send it away to be fixed but you must agree to a charge of up to $1600 because we don't know how far the damage has gone. Me: It all works except a few keys. Apple: That's the deal, and actually we'd recommend its not worth repairing and you should buy a new one.
