Not 0%, but a drone center can have a few people operating many drones, so the labor cost is distributed there too.
Is that more Orwellian than say anti-theft camera systems or red light cameras at stoplights?
I don't always use channels in the code I write.

For example, let's say I have []foo as input and I'm going to call a service on every element of the slice.

You could do it with channels, but oftentimes I'll reach for creating a slice of results and passing each goroutine an index into the slice. That way I can avoid any overhead that comes from having what is effectively a queue with a lock.

It depends on what I'm doing, how I want to treat failures of a single goroutine, etc. of course.

I default to never returning channels unless it's a requirement for the use case (e.g. context.Done() returns a channel so callers can listen for when the context is closed).

Callers can always create goroutines to make your code run concurrently. It's more annoying to erase channels when they aren't useful to the caller (e.g. if you made all functions that make HTTP calls return a channel because you assume callers want a new goroutine, but I already have my own goroutine per request)

Beyond that, some specific examples would be helpful so I can tailor my advice
If you are going to bring numbers into it, then bring numbers into it. What are the cancer risks of alcohol? How does it correlate with the number of drinks per day or week? How does cancer risk correlate with aspartame? What is the ratio of risk from daily chewing of aspartame gum vs a glass of wine? If you don't know, then your argument means nothing.

And even then I'm only speaking of overall risk. They are additive, not zero sum. If you eat aspartame and drink alcohol your risk is higher than doing either one by itself, no matter what the numbers are.

It's a video game so if you're going to learn that lesson from that one, then hopefully you don't play its companion game, Mini Metro, because otherwise you'll conclude that train-centric management is also futile.
Along similar lines, there was a security vulnerability in Netscape Navigator because its HTML parser treated Single Left-Pointing Angle Quotation Mark as if it were Less-Than Sign and Single Right-Pointing Angle Quotation Mark as if it were Greater-Than Sign, presumably because they looked the same and the developers somehow thought that it would be helpful. Of course no markup sanitiser behaved the same and it became a really easy XSS vector because an attacker could use those to give markup to Netscape that would pass through any sanitiser unmodified. There’s loads of examples of Postel’s Law causing security vulnerabilities like this.
Except it wouldn't be 10% slower for 60% cheaper of their item, it's 60% cheaper for the delivery cost which is a small fraction of the overall cost.
I think this is because some jobs translate better to remote than others. We have the trope in popular culture of a bunch of people at work, sitting in a meeting; where being face-to-face is the norm for most of the day.

This translates really poorly to full-time remote.

But there's a more sinister aspect: I've gotten a vibe from some "bosses" that they like big meetings because it makes them feel important. The "perpetual Zoom" helps feed that ego.
My mate Alex was getting email for a guy who should have been at work at Heathrow.

After years of trying to make them stop, he just started replying. “I’m not coming in tomorrow”, that sort of thing.

He never lied. He was not going to be at work at Heathrow tomorrow.

I think that finally made it stop.
Transport adds value by allowing people and goods to move around with less friction. That value is realized by second/third/fourth order effects (bigger labour force available to businesses, money travelling around a wider network causing more price efficiency, improvements in production of goods in one area more effectively being utilized in other areas, all of these things resulting in more tax dollars as well etc etc etc).

These benefits are incredibly hard to quantify and likely don't even really directly/immediately affect the people using the transport. If the airport increased prices to try to capture that value in profit they would just be adding that friction back into the system and the benefits would disappear again.
One thing that is mentioned by ~everyone who tries to reuse cheap phones as computing devices is that the phones are basically not meant to run all the time and fail very quickly when you try to do thing with the screen on for hours and hours at a time or otherwise hold it to high load.

I am sure there are ways to get around this with some cases but it does feel like there are practical issues with the cheapo/used phones. And that's not even getting into having to wrangle the OS.

Maybe someone can make an Android fork that is basically "make this phone a computing device that should last a long time" that you can easily throw onto phones.
Your objection is specifically a cultural objection rather than one based on any physical real world issue.

Japan, many european cities, etc are all comfortable with the provision and use of widespread public transport.

Where it's a problem is those locations where people such as the Koch brothers [1] invested 50 years (1970 - present) and tens of millions of dollars to bend both public opinion and state and city representatives against public transport.

It didn't take much to have the land of the free muttering in lock step about freedumb's, liberty, and their right to roll coal.

From a distance it was like watching lemmings march over a cliff [2].

That’s not true of all marriage vows. It’s not uncommon for self written vows to essentially be a long-winded way of saying “I promise to be a good partner as long as we’re married”.

Personally I use the + feature on email addresses to achieve this.

me+folder@example.com

Maps to the account me and will (if configured correctly) put the mail in a folder called folder if such exists.

The reason you might want many accounts with the same email seem many to me if you don't realise that you can create arbitrary distinct emails this easily.
So I have an amazon.com and amazon.in account. The latter one is my main account but the former one I created to redeem a gift card I got from a survey.
I don’t quite know why, but my combination of first and last name on gmail is such that I get email directed at other people with the same name as me, including financial documents. Wild stuff. I would reply with “um you probably should check before sending” but after a while I just started ignoring it.
That’s true, and it’s the point.

The reality is that there American system sucks by some metrics, and yet by others which are real and not BS, the US economy crushes.

In the end human flourishing, and life satisfaction are more important than GDP, but at the same time GDP is real and it does matter.
Nah, I don't use Chrome so I don't have it installed. I'm not a web developer, so testing across different platforms isn't useful to me. I've used StableDiffusion before, so hacking around to make this demo work in my browser isn't particularly interesting either.

Why rose water specifically? I can definitely differentiate sugary water vs pure water.
I've only seen correlation, not causation. Which makes sense; you likely don't start off drinking Diet Coke - you switch to it once you have some sort of health concern.

FWIW, there are studies that a low calorie, low carbohydrate diet can reverse type ii diabetes (or rather, put it in remission)[0]. The underlying hypothesis came about I believe to explain why people who had a gastric reduction surgery would also sometimes see a remission in their diabetes.

I use a telemedicine[1] which was involved in one of these studies, and which I believe has started to see some insurance coverage because of the savings related to reduction in insulin used by patients. I'm personally maintaining pre-diabetic levels (but have never used insulin).

The American constitution has been highly influential on many countries, and many countries have had experiences that contradict the ideas in it quite successfully.
Possibly, but today EVERY nontrivial piece of software is "AI". It's the new "synergy" for dipshits spouting nonsense.

FYI: in MBA speak, "AI" is now anything that can't be hacked together on top of airtable, outsourced, or done by someone with a GED and six months of bootcamping. If you need someone who isn't perceived as interchangeable cog labor to help build the thing then it's now called AI. Was just in a meeting where a major component for an optimizing compiler was called "the AI".
None of these studies are produced via the scientific method. They are looking at statistical correlation and plucking them out of thousands of complex, confounding, dynamic variables in a very chaotic environment.
That's not a citation, that's even more claims that need backing.

A friend of mine also lost his sense of smell for weeks, he also found that he absolutely hated the taste of hot coffee for months (cold brew didn't bother him)

My original one was simply that anecdotal accounts of loss of smell didn't seem to pan out to a significant difference in frequency compared to other common cold and flu's.

Why not have the API take an allocator as a parameter? Pass in pointers to malloc, realloc, and free. Then the library can use your static allocator (or some 3rd party malloc such as jemalloc, or your own arena allocator for that matter) or it can default to the system one if you pass null pointers instead.

Nah, you can’t hurt pure evil. It just sits there, awaiting its next victim.

I hate that beast, but it’s my beast to hate.

You can’t just talk shit about it from your comfy chair, or sitting on the toilet with no circulation to your feet, or whatever — that’s something you earn.

You earn it with mild first degree burns on your right leg and tinnitus like the rest of us.

If I seem abrasive and unnecessarily combative, it’s probably just the incessant itching of my leg and the trauma from driving that thing.

No, we just hate google maps. You can only shove people so hard before they leave.
It doesn't in terms of agreement on purchases. But it makes the actual logistics of balancing the checkbook easier. You definitely know that you are or are not overdrawing.

(fwiw I use joint accounts, but I can see the benefit of separate accounts if both people are working or otherwise busy and there isn't time each night to balance the checkbook.)
Apple has documentation about using icloud passwords from Windows[1]. I tried setting it up a while back but it doesn't support Firefox. If I recall correctly, you get links to the extensions from within the icloud app on windows.

I'm not sure it's all that easy though. We don't entirely know how LLMs do some of the things they do, and we can't interpret what's in them. They don't internally look up particular sources, it's just a big mess of connection weights.

Maybe my simple scheme would be all it needs. Or maybe it needs some new breakthrough and right now nobody knows how to do it. I was hoping some resident expert could let me know.

Traveling Salesman is NP-Hard. Don't think it is solvable with current technology.
Public transport is not run at a loss as a form of wealth distribution, it's run at a loss because the impact on the economy/society via enabling people to move around more freely is not captured via ticket prices.

It's no different from building roads or sewage systems - you don't try to directly capture the building cost from the people using them because the higher order benefits from having a healthy, growing, functional society (both in the general wellbeing of the population, and in tax revenue) outweigh that.
The strict aliasing optimization in gcc in theory can cause problems (which is why many, including the Linux kernel, disable that)

This study is saying couples randomly chosen to merge finances had better relationships, which doesn’t really align with your advice.
The states over time, have been designed so much that issues cannot get much more than 50% agreement on topics though.

A quarter of states is meaningless when states exist specifically to vote a certain way, rather than to represent groups of people
PPP is usually meant to compare economies and control for differences in cost of living, not comparing time periods. Inflation is when you compare the same economy in two time periods.

Furthermore, economic growth is measured in "real" dollars, aka, excludig inflation. If US prices doubled as you say, then their economy is therefore now four times as large in the new, inflated dollars.

None of this has anything to do with fiat currency. The same would be true if you measured in kg's of gold, but you'd have to account for the gold-cost of living ratio instead of fiat dollar inflation.
Well no, they stopped him to investigate after the pattern recognition. They used a K9 who alerted. Turns out the system was right on the money because there was criminal activity.

>Yeah, the memory is overpriced. So are eyeglass frames (rimless are especially overpriced)

That's not a very good comparison. Glasses are important for helping the visually impaired, while Apple memory is just an add-on for a luxury computer.

>But as long as you can afford it, a few hundred dollars isn't that much spread over a few years.

It is that few hundred dollars is a 10x markup over market rate (I've checked, and Apple's markups are actually that bad).

>You can get a not-MBP and have a clunky experience [1] but save some money, or spend a the extra few hundred for a MBP with enough memory to be a great experience.

I don't think my experience with my current PC is clunky, and if I get an M1 macbook, I'll be using Asahi Linux instead of MacOS.

If you bought a product and the vendor said it will be supported for X years with updates — that’s all you get — X years. If you want to keep using a product for X+1 years, that’s fine, but that’s on you. I agree with your sentiment that hardware shouldn’t be disabled, but I don’t expect security updates past EOL. You can’t expect a business to keep supporting a product longer than they originally said they would (without compensation).

But these are enterprise products… support contracts last a long time. More than enough time to migrate (or past the time when you should be migrating). That’s part of why the long term support exists in the first place.
> the idea that minimum wage is supposed to be "livable" is a modern notion.

A notion that dates back centuries and one specifically enshrined in law in Australia, a G20 country, since 1902 (ish).

I dare say other G20 countries also support this notion (aside from any antiquated holdouts still clinging to non SI units).
Travelling salesman is a largely solved problem, but I'd say this problem is larger.

As soon as humans and the real world are involved, seemingly contradictory criteria need to be met.

Algorithms like A* search may not be able to capture these criteria robustly enough.

Example: a driver may be assigned the optimal route, but because they are human will not want to sit and wait for 15 minutes between several of their rides

A* is great for path finding but it's not a global panacea for all subproblems related to ridesharing
Also our physiological sensory and processing equipment (ie, eyes, ears, brain...) translates analog / continuous input into discrete electrical signals; a given neuron fires or doesn't.

I really like this idea, but. I've been thinking about this, and also the fact that Pingdom, etc. seem to consolidate. Is there really a big market for "simple monitors"? If you are small, you probably don't care much/do it yourself/don't want to pay. The moment you grow bigger, you have many more comprehensive options available to you like Sentry, Datadog, PD, etc. that offer not only uptime alerts but all kinds of other stuff for a range of budgets.
It's "The Wind Rises" - from Paul Valery's famous closing stanza of "Le cimetiere marin" (The Cemetery by the Sea)

"Le vent se lève !… Il faut tenter de vivre !"

"The wind rises... we must try to live"

To me it denotes a sad, stoic acceptance that things are about to go down badly, but we must somehow survive.

My mother went her entire 59-year life without a sense of smell. She heavily leaned on my dad to check if the meat was off, if the house smelt before guests arrived, etc. But overall, I felt it was somewhat of a superpower. Who wouldn't love to say they have never experienced the smell of a poorly maintained public toilet or someone else's fart?

She spent about a decade of her life trying to find solutions before giving up and just living with it.

You are lucky, now is relatively calmly period of war in Ukraine, (formally geography center of Europe here), so you could visit country, look, sense smell of war, and flee on first signs of danger.

I guarantee, you will not have comparable opportunity in nearest 10 years.

To be strict, looks like China planning to occupy Taiwan in nearest 12-18months, but I think, their war will be very different.
Because I do want a home base. I want a large workshop for woodworking, painting, and maybe ceramics. I want a place to have musical instruments. I want a great home theater, gym, sauna, and an amazing kitchen. I want space to work on my motorcycle.

Land is important. I want a big garden and lots of space between me and my neighbors. I want quiet nights and a dark sky.

I could never afford this near a city, but once you drive thirty to sixty minutes, there are a lot of options.
Midlife crisis is about recognizing your mortality and limited time left, and looking at what you have done and finding it comes up short to what you hoped for your life.

The reality of how little time you have left is a key component, that death is stalking every decision and will likely curtail some plans.
Things can definitely improve. I'm thinking of Copenhagen, which is probably the most bicycle friendly city in the world; it's taken about 50-70 years of bicycle-friendly policy and it's only now reached a point where number of car trips per day and bicycle trips per day in the city are equal.
Hallucinations in AI: A Comprehensive Guide
Every time I've heard about drone delivery; it was either implied or directly stated that it would take a long time to be generally available. It's easy to forget that, historically, "tech" would often take decades to develop. (The rapid changes we saw in the 1990s and early 2000s is unusual.)

One thing that I think would be interesting is "hybrid" drone delivery: A delivery truck could drive to a central location, and then a "swarm" of drones could drop off packages at homes within a small radius.

oh god, I just realized this study is based off self reporting isn't it? In other words couples are happier when they perceive they have a joint checking account with no separate accounts.
Yes, that's exactly what plus addresses exist for!

It seems to me like all benefits of the "exact same email, multiple accounts" feature are vastly outweighed by the inconvenience for users simply forgetting that they already have an account, and creating a second one by accident that way.

I mean, even I end up almost creating an account by accident every now and then (mostly on sites using the horrible "signup is the default, login needs one additional click" pattern), and I do so using autofill from a password manager!

Anything natural is most likely OK? So by your estimation if you were lost in the woods, at least 50% of everything you'd see would not just be edible but actually good for you? I mean, just to cite an example, if you chew the seeds of apples and swallow them you're eating amygdalin, which is a chemical that reacts into cyanide in the stomach. Asbestos is a naturally-occurring mineral.

If anything, entirely the opposite is true. Most things in the world are either inedible (in the sense that they're immediately mechanically harmful to eat) or toxic in some way or another, at least without some "artificial" processing.
Sure, feel free to compare American poverty-level people to poverty-level people in countries with stronger safety nets.
This is true, however these known criteria can be added in, thats the whole point of the heuristic in A*.

Likely one of Uber/Lyfts greatest strengths in their algos is discovering the E[X] of those heuristics. This could probably be captured from the human dispatchers as well.

Surprisingly you can solve massive TSPs using heuristics. The solutions are not guaranteed to be optimal, but they can get very close to optimal without a crazy amount of computing power.

The Concorde TSP solver can apparently solve instances with 85.6k cities to optimality. Pretty amazing!
