> To me that's weird because calling the elevator is long running IO in a separate thread - might as well start it asap.

Oh, man. I've felt exactly the same way wrt. a lot of IRL scenarios, implicitly optimizing the number of "threads" I can do tasks in, for instance:

- starting an automated but lengthy task (e.g. choosing Nixpkgs PRs to automatically review) before going out for a period of time

- starting the microwave heating food before going to the toilet

- pressing the elevator button before tying my shoes (in a private elevator scenario)

Distinct from multitasking, which splits your attention, here, you can still dedicate attention to a task at hand while knowing in the background that a thread is running. These types of behaviors may not really do all that much long term, but it sure feels nice you optimize IRL scenarios.

I think about historical, 2-phase sleep a lot.

One reason it will be difficult to restore natural sleep cycles is that life has become increasingly complex; we have exponentially more responsibilities than our ancestors had.

In short, we are unlikely have a couple more hours to add to our sleep periods.
Or mabye he used the Wi-Fi and they detected that his phone was loggedin with the same ip. I don’t buy that people are being corrected on physical location. Some services probably do, but the normal ad network’s? Nah. where would they get my actual location data from.
This is absolutely wrong. Especially when the formulation of the idea depends on extremely advanced knowledge of the topic.
> Literally anything from iPhones to a single duct tape.

I think this explains it. Cheapest ducktape on Amazon is like $3.48 with free shipping for Prime users. Ordering one such tape every other day only costs $52.20. At some point you stop caring how much externalities it might be causing by clicking "Order Now" in Tuesday 3:40 AM just for a single M4x20 screw you forgot to add earlier in the day.

> They will literally spend $500 on something that is $50, because they like Amazon's reliability around delivery, the purchasing is very smooth, returns are smooth etc.

I tried to avoid Amazon a couple times, to give other stores a change and all. Wasn't that great, and it was more expensive.

Bought something on Best Buy, thought about returning it. On the product page and invoice, didn't say the date I could return. It only said the return periods where on a FAQ. FAQ didn't have a specific category for that product. I thought it was something (with 30 day), but when tried to return it, got a 'no' because it was 14 days. Why not add how many days in the product page? Why not show me the exact date on my order details?

Also tried the same with books, buying on Indigo. Bought an extra book to get free shipping. The price of the books where already a dollar or 2 higher than Amazon. 10 days delivery, and one of the books has some marks like someone put a paper over the book and scribbled on it. Never had a problem with Amazon, and it's cheaper and delivery is like 2 days.

Ah nice, it's refreshing to see that level of documentation for an OSS project, even if it started as a commercial project.

Totally agree about not having too much documentation - sometimes outdated documentations is worse than no documentation at all.

I've got that in our attic with a nice little light switch in our bedroom to turn it on. Crack open the window, turn on the attic fan and the whole house cools down nicely.

The only problem is that I forget to turn it off in the morning. Out if sight out of mind. Switching it to a timer is on my list.
McMaster is pretty good as a consumer for fastener hardware, a good assortment of various geometries of various metals, and mixing supplies in sense of both availability, exotics (such as aluminum flake 12.9 screws), and absolute zero bullshit with regards to knowing what you're actually getting, the fact it's always there, and that it's same day-next morning delivery in most parts of the US.

I've had my fair share of actual 12.9 steel screws from Amazon that are actually 12.9 steel, and my fair share of 12.9 steel screws that were actually made of cheese.

Plus... this is something maybe only a CAD user can understand - McMaster Carr provides an outright sex bible of importable 3D CAD objects.

Like, I really thought my CAD instructor in University was joking when they said McMaster would be your Bible if you're ever designing in CAD for hobby/industry. Then I got a job, and holy shit were they right. So I like to think whenever I pay slightly more on McMaster for what I could get on Amazon or eBay, I'm supporting the bible for all of the goodness it's given me for my hobby designing and in making actual work less stressful as well.

I agree. Looks to be just a pet project. It's missing the "why"
Ah, I see the confusion. By "individual researcher" I do not mean "independent researcher" - I mean the researcher, considering their motivations as an individual person. They can be part of a group of researchers, and they're generally working for some employer. After all, the "individual researcher" in academia is generally working with a group - e.g., the example given about the grad student who is "every professor's dream" only makes sense in the context of that relationship - and that produces the negative pressures described.

In particular, I mean that a researcher in academia, as a person (an "individual researcher"), is motivated by the demands of academia to get grants and fill their CV and is therefore incentivized to conduct dishonest science to make that happen, and a researcher in industry, as a person (an "individual researcher"), is not directly incentivized to conduct dishonest science - perhaps there's dishonesty in how their employer gained funding or what they do with the research, but that doesn't compromise the accuracy of their research, motivate them to game the peer review system, etc. The researcher as an individual has the choice about whether to be in academia or industry.

So, I don't think I follow how similar situations will arise in industrial research groups. (Though, as mentioned in my original comment, I'm probably missing something, because there were researchers from industry who coauthored these papers.) Even among a group of researchers in industry, the incentives should be to produce things of value to the employer, not to play the part of productive-looking researchers.

I'm specifically not claiming that independence will solve anything; the fundamental problem is funding, and (as you say) nobody is going to want to live out of their car to do good research. And you need access to facilities/tools of some sort to do your research; my claim is that industry can provide those at least as well as academia can, not that they are unneeded. Admit that you're constrained to work at a place that can fund your research and that no place exists that will pay you well and leave you to your own devices, and then find the place whose incentives to fund you are least likely to compromise your research integrity and most likely to reward you for actual good work. At the moment, at least in the society where I live, that happens to be industry.
> Nothing prevents showing both the item price and the shipping-included price next to each item.

Nothing prevents the sites from doing that, but most sites don't do give you an option to see total price on the product page.
Is a sports team unethical when they talk about being the best? Seems pretty unethical to think your better than the other team, right?

No, it's just a thing they tell themselves to hype themselves up and avoid the depressing truth most teams face, "we're far from the best and probably never will be the best, and there's a good chance we're going to lose this game".

Well, in work the depressing truth is "my boss is my boss, I have to do what they says so I can eat". A little chant to remind yourself that work should, ideally, be mutually beneficial and based on mutual respect, and that you're not a slave to the company and its politics is all this is.
Absolutely. I'd pay more if I could look at Amazon without any of the third party garbage.
Great industrial shelving for the garage, that hard-to-find bolt with the specific threads, or rock salt for icy driveways. The second time you call them they greet you by name. You can say a part number, a quantity, thanks, and hang up, and you're getting a box of awesome really soon. McMaster-Carr is an amazing company for people who do things.
> Ive def noticed Amazon becoming more and more of rip off.

Yes, and more and more counterfeit goods.

They must feel really confident with their market position (ie, monopoly), because they just don't seem concerned about counterfeit products.
You’re a CTO so I imagine you’re hiring mostly directors and VPs and it comes down to whether you like the candidate or not. At a lot of companies you just have to be noticeably better than everyone else because after 5+ employees interviewing 5+ candidates, most managers have had enough with the time the team has sunk into that process. As a candidate, if you can find out how long the role has been open, you can really play ball.
Have been an Amazon customer since 1996. Have signed up for Prime dozens of times -- for the free trials. I have never paid for it. I would never pay for it. Seems like a ripoff. In the early days they would warn you: if you end the trial you will never be allowed back into Prime. Heh. Then they would send you emails begging you to try it out again. So I would. Used it for "free" shipping. Over the years they added lots of other stuff like the movies/tv shows but the picture quality was lousy and they rarely if ever offered multichannel 5.1 audio. Another reason I have never paid for it.
That said, keep in mind that in a negotiation, you always have leverage. Some of the best negotiation advice I ever got was "the very fact that they're still talking to you means you have something they want."

That sentence helps both with confidence and understanding the dynamics at play.

(The trick to negotiating well, then, is being good at finding an agreement that leaves you both happy while still talking to each other. But keeping the talk alive is the most important bit.)
Using a phrase like "fumbles around" still sounds like you're placing it on a lower rung, whereas I would say that basically everything I've ever done has been an iterative, collaborative process, including in situations where I'm highly confident of both the problem domain and technology choices. There are always going to be new discoveries made during implementation, and you can't have a written-in-stone design doc that prevents anyone on the team suggesting a refinement.

For myself as an opinionated person in a devops role, the vision that I try to communicate to my colleagues is mostly broad principles like configuration as code, helping people help themselves, consolidation of systems, and then some more pointed specifics like don't touch prod, don't make changes without a consensus, start by understanding why it's the way it is before changing it, etc.
It's usually largely under "regular" market value. ( but that's still a bet over the life expectancy of the person ). Also you basically don't pay interests. And in some times you can use the property : the seller use the money to pay for a nursing home for example.
According to this:

https://plato.stanford.edu/entries/church-turing/

"In his review of Turing’s work, Church himself acknowledged the superiority of Turing’s analysis of effectiveness, saying:

computability by a Turing machine … has the advantage of making the identification with effectiveness in the ordinary (not explicitly defined) sense evident immediately. (Church 1937a: 43)"

Moreover, Gödel himself (as well as other mathematicians) found Turing machines and Turing's thesis to be more persuasive:

Gödel also found Turing’s analysis superior. Kleene related that Gödel was unpersuaded by Church’s thesis until he saw Turing’s formulation:

According to a November 29, 1935, letter from Church to me, Gödel “regarded as thoroughly unsatisfactory” Church’s proposal to use λ-definability as a definition of effective calculability. … It seems that only after Turing’s formulation appeared did Gödel accept Church’s thesis. (Kleene 1981: 59, 61)

Gödel described Turing’s analysis of computability as “most satisfactory” and “correct … beyond any doubt” (Gödel 1951: 304 and *193?: 168)."

For what it's worth, I do think you've started an interesting discussion!

You're allowed to have an opinion that you prefer lambda calculus over LCMs (logical computing machines -- a better term for Turing machine's that Turing favoured) for conceptualizing and reasoning about computation mathematically.

Myself, I find Conway's game of life to be the superior framework over both lambda calculus and Turing's Logical Computing Machine :-P
A putting a clause into a contract they enter into with B that B may not sell to C (competitor to A) is obviously anti-competitive. Think of the whole Intel "you can't buy AMD" clauses with OEMs.
> Also have to factor that Amazon's customer service is fantastic.

I only need their great customer service because of the poor quality products they are shipping. With other retailers, I don't know how good their customer service is because I almost never need to utilize them.
Yeah, Amazon loves those bubble bags and even just the mylar ones. They aren't careful enough about what sort of items go in them. Many items are fine that way but more than once I've gotten completely destroyed packaging around an intact item. Fine if I was simply going to use the item anyway, not so good if I was ordering it for someone else. I've also had a couple of cases where I was surprised it survived.

I suspect they are playing the odds, accepting that they will have to refund a few items that got smashed from inadequate protection.

A bare minimum level of diligence is required before denying a claim. Else you -should- run into bad faith, punitive damages, action from regulators, etc. It's not some super magical extensive investigation to realize that you shipped a box that weighs much less than the item and that there's likely a big problem.

There may be very valid reason to shortcut claims and to grant dubious claims of high value customers. But you really shouldn't just ship an empty box and say "sorry, you're not getting your money back unless you sue us". (And worse, break the customer's existing digital content if they do, because you can hold it hostage).

I mean, I get that it's financially appealing to externalize the costs of in-warehouse and in-transit shrinkage to random low-value customers, but brah-- that's just not right.
You may also want to check your neck posture. I've found that, in my case, using laptops invariably leads to bruxism due to poor ergonomics.

Quitting laptops and using a proper desktop, or a laptop stand plus an external keyboard, was like toggling off the bruxism switch. It went off in a week. Plus, I stopped suffering from horrible migraines.

In order to repair your enamel a bit and keep what you have you may want to try toothpastes and creams that contain enamel-like ceramics. I've had spectacular results with a combination of calcium salts, fluoride and hydroxyapatite and ceramics (Novamin). There are better things to add up into the mix right now, such as self-assembling peptide scaffolds.

"I've been working on this company for 2 years and am finally starting to look for funding."

Do you have any paying customers yet ? It seems like you are saying that you worked for 2 years before getting customers (I am assuming based on your tone) and now you are dependent on funding to move forward otherwise you are feeling burnt out ? I admire your courage so far but please tell me you have at least a few paying customers ?

Nothing makes you happier than knowing that product/idea is validated with at least few (even if handful) paying customers. If that is not the case, no wonder you are feeling what you are feeling because you are in that mode where one fine day with funding, everything will be great.

All the best. I just wanted to give it to you straight as another fellow founder. Whenever I feel down or stressed, I look at the paying customers we have and the validated product which makes me keep going even though growth sucks at times.

The point is that one of the basic properties of messaging encryption is forward secrecy. It's an argument about how messaging is different from backup, package signing, file encryption, distributed logs, file transfer, and secure transports (though some of these really want forward secrecy too), and how PGP advocates back-rationalize not needing forward secrecy so they can defend their weird archaic tool.
Many well-run ecommerce sites do let you enter a zip code and see shipping quotes. Some don't until later in the checkout process, and I'm more likely to abandon the checkout on those sites. I won't hesitate to bail at the last moment either if I don't like the final price on the deal.

We're talking about a difference of seconds in the checkout experience. It adds to the perception of convenience, but but I don't see the miniscule time savings of the Amazon experience as being worth a higher price on the same item I could get for less elsewhere.

I've wasted far more time with Amazon trying to decide if an item is legitimate, and dealing with returns of broken, counterfeit, or misrepresented goods, than I have saved in their checkout experience.
I was debating that. I always considered a loss leader as something to get you into a store to buy more expensive things. This is similar I guess...but I don't think it's identical because it isn't about getting you to buy more things(at that moment). More about getting you to not check out competitors. Perhaps it still applies.
I wonder how long the momentum will run on this working. There’s still a lot of earned assumption that Amazon is a competitive price.

I’ll usually let a slight increase in price slide for the convenience, but I’m always looking for a reason not to use Amazon if I can - and a rip off price is a good trigger for me to be patient and get the product next week with a smaller shop.

What this person mentions is really just the tip of the iceberg. They link credit cards to phones because GPS coordinates and WiFi networks nail down your address, which they cross-reference with the billing address of credit cards.

They know who are you sleeping with, or if you aren't sleeping with anyone. They know your age and all the insecurities you have about your body, not to mention your health problems and every embarrassing fact about you. They know where you've been, where you're planning on going, and your political preferences. They know if you've donated to political parties, attended political rallies, if you voted, where, and when. And they know all your friends.

And we just let them do this. As tech people, we built this. And all the along the way we told ourselves it was fine, because it was very lucrative for the entire ad tech/fintech/startup ecosystem, and us personally.

(1) You need a much better telescope to see evidence of alien life. Something like

https://en.wikipedia.org/wiki/FOCAL_(spacecraft)

could plausibly pick up accidental EM emissions from civilizations on Earth.

(2) Most of the habitable places in the universe with liquid water by far are smaller bodies that are heated by tidal or geothermal energy. The average "gas giant" seems to have tide locked moons producing situations like

https://en.wikipedia.org/wiki/Io_(moon)

https://en.wikipedia.org/wiki/Europa_(moon)

geothermal heat and pressure probably cause liquid water in Pluto. In fact, an asteroid in a circular orbit around Earth will have an equilibrium temperature not far from the freezing point. We know some asteroids have a skin of some kind that traps gas, plus probably also mechanisms that keep votatiles stuck the way gas gets trapped inside bread. I am certain that some asteroids somewhere in the universe hold enough pressure to have liquid water.

If humans are going to become starfaring they will go through the following steps:

The Photographer Who Fought Nazis with Her Camera
I don't know what this is supposed to prove. Poe was a failure whose writing was never popular during his lifetime. The fact that he is better known since his death is entirely due to the activist efforts by Ivory Tower academics and English teachers to make the rambling writings of an ancient hack into mandatory reading for students.
The magic of having 12 equally spaced notes in the chromatic scale is that specific important intervals are closely approximated by ratios of small integers, and you can transpose a piece to any key (this doesn't work if you tune to exact ratios). Small, integer ratios supposedly mean the frequencies will sound similar or related because the peaks and troughs sync up every 2-5 cycles.

I say supposedly because studies have found remote tribes, played the, the same note, but in different octaves, and asked if they're the same of different. A lot of people couldn't associate that they're the same, which would imply these ratios aren't actually important. I have serious doubts about these studies, though; from a signal processing perspective, 440 Hz and 880 Hz are related at a physical level, so it's surprising that recognizing this similarity isn't almost innate.
