Before buying something like this for my home, I'd need to know:

* Is it safe for babies and small children (whose thin skin and developing eyes might well be much more vulnerable to UVC)

* Is it actually safe for all adults regardless of skin type, colors, dermatologic conditions, or was it only tested on a few healthy college students of one particular ethnicity;

* Does it accelerate degradation of household items, plastics, fabrics, books, and paint; and if so, by how much


> It doesn't make any sense.

It makes perfect sense to me. I rely on that feature. My monitor is big and it's much easier to use the big screen to sort vacation photos and delete the 90% which are garbage and not worth preserving. When I delete the garbage ones, of course I want to delete them everywhere. (And if I accidentally deleted the wrong photo, I can undelete within 30 days.)


What doesn't make sense is that it is not explicit, and it is not easily and clearly configurable!


> This seems incredibly inefficient.

Very inefficient but good for safety: if an engine is failing, you hopefully might discover that while taxiing rather than when you are in the death zone 25 meters up in the air.


Not an expert, but intuition suggests this probably isn’t true.

If an engine is going to fail spontaneously it’s almost certainly going to happen at high thrust, not while at idle or very low thrust values during taxi.


Your intuition is wrong.

Engines experience issues when changing speeds (especially start-up) not when at steady thrust output.


Fair enough. But delaying engine start-up until the aircraft has nearly finished taxiing wouldn’t have any effect on the way the engine operates during start-up. It just means it would spend less time at idle or near-idle speeds during taxi.


In the original Russian, Dostoyevsky requires the slow treatment. He loves the sort of 1/3 page long sentences that perplex the fast-path parser and force the reader's brain to swap; as if he wants to drive you mad so that you can better understand the madmen whom he writes about.


Interesting point of view. But it's common for a man to get a work tool as present (e.g. a drill or a set of wrenches), with the obvious implication that the man will usually be the one who will have to use that tool to fix things around the house - and I have never seen anyone find that offensive. So what makes the vacuum cleaner different?


For anyone that like to do DIY, that's not a work tool, that's a play tool that is coincidentally a work tool to do work.


Same thing back at you. The vacuum is a play tool to anyone who finds cleaning to be “fun”.

There’s whole genres of cleanup games on steam which are extremely popular, profitable, and well reviewed.

One of my favorite vectrex games is a Pac-Man clone where you play as a vacuum.


Powerwash simulator is occasionally fun. There's shiny rewards, I don't have to deal with potential bad weather, and there's no random patches that take 20 times to get rid of. If I don't feel like powerwashing simulator, it will wait for me, forever, with no ill consequences or social judgement.

If I never wash my actual driveway, the same is not true. Therefore I will need to wash it at times when it's unpleasant or I don't want to, and it will take longer than powerwashing a driveway in Powerwash simulator.


In this scenario (again, everyone’s situation is different) DIY is more often a hobby for the husband. Repairs are infrequent enough that you could just hire someone as needed, but the husband chooses to do it.

Perhaps more importantly, it’s not his full time job.


Without context, the reaction is bizarre. There must be some back story that you omitted; maybe something about the mother previously asking other people in the family to vacuum, and being ignored?

My wife and I, by the way, are giving each other a joint New Year gift of a fancy robot vacuum cleaner: it's the best sort of gift, useful, elegant, and something that one would be reluctant to spend the money on otherwise.


A joint gift is very different, and a joint gift of a household appliance that reduces the work doubly so.

The reaction is a result of the gift implying that the work is the responsibility of the individual recipient.

It's not a universal reaction, but common enough that it is a frequent trope in movies and TV.


> I’d appreciate hearing what others would do differently

Very naive answer: before doing anything I would start by playing around in the GCP pricing calculator [1] to figure out how much it was going to cost during development and in production. Did you use the calculator tool? If so, were its estimates accurate?

In much the same way as you differentiate between "O0" and "00", or between "I1" and "11". (For example, to avoid ambiguity, a standard may prohibit the use of З in a position where 3 is allowed.)


There was also a wealthy suburb with an actual gang whose existence was swept under the rug for years until they murdered a random 16 year old: https://www.newyorker.com/magazine/2024/07/01/how-a-homegrow...

The cops' reluctance to investigate probably had something to do with the fact that some of the gang members were white student athletes with very wealthy families.


That's a real thing that actually happened, my school administration was worried about "ethnic" gangs and rappers they saw on MTV turning 11 year old white kids into, using their words, "gangstas". Same people were running around like headless chickens about "rainbow parties" and FPS games a couple of years before.


If the author is disturbed by criticism and nitpicking, they are completely right to make their words private. (The old saying "if you can't take the heat, stay out of the kitchen" is usually said in mockery. But I suggest that it can be read straight, not as mockery but as practical life advice.)

All that said: the author's words

> But, it's no longer worth it to me to offer my knowledge and wisdom.

seriously annoy me. What kind of pompous sense self-importance does one need to have to unironically claim to possess wisdom?
