Does annybody worry about sabotage if you don’t tip? Eg the cashier does something to your food? “Nice muffin you got there, I’d hate for it to get accidentally sneezed on.”
I recently bought my mom flowers for her birthday. Despite the price showing no delivery fee, the final price included $15 delivery charge, $8 service charge, taxes, and then asked me for a tip.
I chose no tip, expecting the delivery and service charge should cover everything.
The flowers were left on her front porch in below-freezing weather, they didn’t even knock or ring the doorbell. Luckily my mom happened to open the door and saw them before they completely froze.
So was the delivery person incompetent, or acting out because I didn’t add additional tip?
Two thoughts on situations where the 555 may be preferable, if anyone has experience how these compare :
1. Low-noise applications. I’d naively expect the 555 to be less noisy than a clocked digital microcontroller, though it’s been awhile since I’ve worked in this space.
2. Low power applications. How does latent power draw compare between a 555 and a typical low power microcontroller?

The 555 is very power hungry compared to a typical cheap low-power microcontroller. IIRC there are lower power variants but the 555 still fundamentally does timing by draining current through a resistor, which is going to result in losses.

TTL ones were exceptionally noisy because the output transistors "shot through" - both output transistors would conduct for a moment shorting the supply rail to ground and crowbarring ridiculous interference onto other parts of the circuit.
And there's another reason not to recommend them - no one sane has used the bipolar version since the Carter administration but they're still out there and it's another pitfall for beginners.
"Home & Garden Television". Lots of shows about flipping houses, etc.
It used to be far more instructional (Julia Child-esque) before it and Food Network got swept up in the reality TV craze. It still has the "bones" of its former self though.
Even in your own car dropping off your friends or family at a UK airport (at least the London ones) requires paying a £6 fee now. Just to get to the dropoff area, even for 30 seconds as you say.
At Edinburgh airport, you can park at the Park and Ride nearby but it costs a tenner to get from there to the airport - a distance you could walk in about 20 minutes.
Right, but what do you think the alternative is? There is limited space close to the entrance of the terminal, it has to be rationed somehow. Also what happens in practice is people take advantage. A trust-based 30s wouldn't work. Even with the current fees you can hang around Heathrow drop off and see the police having to move people along, check unatended cars, etc.
There's limited space everywhere. It is rationed by people not wanting to be there. There's limited space at the baggage claim but nobody is charging you to be at the baggage claim.
You think people don't want to drop off at the airport? There's literally a multi storey full of short term parking at every Heathrow terminal. They wouldn't fit in the drop off area at all.
You are charged to be at the baggage claim. The airline pays it on your behalf, from your fare.
And what's your experience of other world airports? Have you been to Heathrow? What about somewhere like Changi? It's not just the dropoff that sucks at JFK.
Public realm is almost universally terrible in America because Americans rarely leave and don't experience anything better. It's bad, actually, to wait in traffic for a large portion of your life.
See also: the revolt over NYC congestion pricing. The congestion fee in Manhattan should be $50 or more.
I've only transited through Heathrow, I haven't tried the driving experience there. I have tried it in various other airports in Europe and China. None of them charged money to drive up to the terminal either and they were all fine too.
Sometimes the American experience isn't different from the rest of the world and it's your experience that's unusual, you know.
You understand that e.g. in Chinese cities they restrict car ownership and you have to enter a lottery/bidding system to get valid plates. Cars are a luxury. European cities have their own restrictions and discouragements. Rationing happens in many ways.
I have still never experienced an airport with pick-up/drop-off traffic as bad as JFK, and I've travelled to almost every country in Europe, plenty of countries in Asia, and Canada. Maybe South America can beat it though, TBD.
That's probably a "JFK is unusually bad" thing, not an "everything is terrible in America and those idiot Americans don't know any better because they never travel" thing. I haven't been driven to JFK since 2001 and I don't remember what it was like then, but driving anywhere around NYC requires great patience.
London is worse _overall_ for traffic than NYC, so I don't think it's that. I like America and Americans, but it's a fact that they don't travel much. JFK is not just bad for drop-off, it's chaos and run-down in general.
In my experience, it's a superior approach for code you wrote yourself in a repeatable crash. You have the whole programming language at your disposal for building a condition corresponding to your bug, and any kind of data dumping.
I fall back on debuggers when the environment is hostile: Half understood code from someone else, unreliable hardware (like embedded), or debugging memory dumps.
But before both, the initial approach is thinking deep and hard, and reviewing all available evidence like logs. If this is not enough, I try to add better troubleshooting abilities for the future.
My daughter is deaf and goes to a specialist deaf secondary school in the UK.
Five years ago ARISS-UK pre-arranged a connection between the school and astronaut Mark Vande Hei on one of the ISS flyovers. Various students got to ask questions directly to Mark in orbit. It was the first contact between ISS and a deaf school.
An “aural” deaf school? This seems like a fairly harmful approach. I know that approaches to deaf education are quite fraught, but pushing students to communicate orally and not allowing sign language in the classroom seems like it’ll set a lot of students back educationally. It essentially turns deafness into a learning disability, which it doesn’t need to be if you just allow sign language. (It also shuts the students out of mainstream Deaf culture, which I imagine a lot of them will resent later in life.) I am surprised that a school with this philosophy still exists, frankly.
They’ve been doing this for over a century, it’s probably the top deaf school in the UK, and has the support of nearly the entire deaf community.
Most of the students have either some degree of hearing or use cochlear implants. I think nearly all, if not all, students use either hearing aids or cochlear implants.
The classes are very small (eg 5-6 max usually), students are arranged in a U-shape around the teacher so they can read lips. And there’s a special wireless broadcast system so the teacher wears a microphone and sends the audio directly to hearing aids or cochlear implants.
Regarding deaf culture, most of the students use BSL on their own outside class, and my daughter learned BSL from her friends there that grew up with it. Coming from a mainstream primary, she found “her people” here, discovered deaf culture and a community that shares the same struggles she faces.
The idea is that by teaching in BSL the students are further restricted in their ability to function in a hearing society.
I’m curious if you are deaf yourself, or work with the deaf. All the teachers at the school are trained teachers of the deaf, some are even deaf themselves. And I haven’t heard any complaints about the aural nature of the learning (except from the reservations of a few parents before sending their kids there, and I don’t think any of these parents regrets this after their children started there.)
