> How is it that it can be significantly cheaper to rent the physical disk than to stream the movie once?

Price discrimination or price segmentation is the technical name.

If you are selling an identical good which has near zero marginal cost to reproduce, then the way to maximize your profit is to sell it to each person for the maximum they are willing to pay.

Ideally, you want to sell (or rent) the same movie or tv show or song to someone willing to pay $5 for $5, $10 for $10, and $1 for $1.

In practice, it is logistically infeasible to target each and every person’s maximum price, but you can try to target populations as a whole. For example, grocery stores with no discount to people who are willing to pay more, versus giving out paper coupons or online coupons to those willing to spend time to save money.

In media’s case, I am assuming that the media sellers are betting the people willing to buy online are willing to pay more, on average, than people willing to go through all the trouble of renting a physical disk.

At least in my case, it would ring true. If I really wanted to see something, I would not care about paying $5 in the moment on my TV and start watching in seconds, rather than remembering to get and dealing with a disc from a Redbox kiosk for $1. But there are people who would want to save the $4, and so the content sellers are able to get $5 from me and $1 from the person using Redbox (although they are also losing sales from people not willing to buy at $5 online, and not willing to pay $1 at a Redbox, but the bet is that population is smaller than the total of the other populations).
I like the lispiness and features of ITERATE but it breaks source location for debugging errors in SBCL with SLIME. Instead the ITER form is indicated, which dampens my enthusiasm for it somewhat.

(defpackage :test
(:use :cl :iterate))

(in-package :test)

(defun test-iter ()
(declare (optimize (debug 3) (safety 3) (speed 0)))
(iter:iter ;;; <-- highlights whole ITER form
(sleep 2)
(error "test")))

(defun test-loop ()
(declare (optimize (debug 3) (safety 3) (speed 0)))
(loop
:do (sleep 2)
:do (error "test"))) ;;; <-- highlights ERROR form
Thank you!

In case one day you'll want to increase its use, I suggest to put it at least in the homepage source (where we go check if we find there a literal 'rss', or 'feed', or maybe 'xml').
I do think carousels have an important place in design: collapsing repetitive but possibly relevant content.

Example:

You are a contractor who makes their living off of their reputation. You have a set of testimonials (maybe 5-8).

A user visiting your website may be browsing for several reasons - and may or may not be interested in what others have to say about you. Collapsing all of the testimonials down into a single carousel shows you have testimonials and allows the user to browse through them if they’d like without forcing them to scroll through each one.

This content is repetitive - if you’ve seen one that conveys enough information - but each one potentially provides incremental reassurance for a user if they need that.
They are aircraft that is cheaper than anti-aircraft rockets normally used. One shot from anti-aircraft system cost 50-200k depending. This is great when the target costs 50 million, but drones costs start from 1k.
I hit on some of those where I live.

2 or more acres: Yes
can't see your neighbor: No
Less than 500 people: No, just about double that at 1k

I consider where I live pretty rural. In my town there isn't a lot of "tech" people that I know of but 15 min away there is a small "city" with about 15k population that has an active co-working space that is all tech people (its like 20ish person group).

Even in the "city" that is 15 min away, there is never any real traffic, not like what you get in a major city. I never worry about hitting traffic, I can come and go to the co-working space at will without ever a thought of "I better leave before rush hour hits".
In >my< opinion, it sounds kinda like you didn't read the Letter from the Carnation Company, or at least didn't quite grasp the point prior to rushing out your simplistic take and weird analogy about horses.

Apple has surely never engaged in change-for-change's-sake as you are asserting. If you step back and consider all the factors in the changes they make - developing high quality materials, reducing size and weight, optimizing yields, durability, integration of technical advances like bus speeds, resolution and energy density, thermal characteristics... on and on, there are probably a thousands more factors that inform the changes they make to any given product.

Not whatever hand-wavey dismissal you are asserting here. Sometimes their industrial design misses the mark, such as with the hockey puck mouse, or the charge port on the current mouse, but these are fairly rare when contrasted against the full spectrum of their ever evolving products.

And that's the whole point of that letter from Carnation. There is a lot more going on behind the scenes that drive these engineering decisions. Simply writing them off with a simple take totally misses the mark.
> - We use cash to rent a building, order pallets of inventory, and sell that inventory locally to walk-in customers.

> - We use cash to buy shares, hold onto them for a bit, and sell those same shares and make money off the spread.

Those two sound like pretty much the same thing.
Thank you, I've always wondered about these but was too lazy to check.
Imagine the life of someone who thinks that this is a good and important change. It's probably miserable-- a slight around every corner and no higher purpose than bulling people over terminology. Instead of anger, try gratitude that you're not in their shoes.
Can't Tesla having satellite maps, the position of the owner and the car make sure a line of sight is even possible?
What about reader mode?
The Raleigh NC area has quite a bit of tech, and if you stay about 20-25 minutes outside of downtown you can get that rural lifestyle while still being close to the city and tech companies. Specifically if you stay south of the city. I have 2 acres and regularly see cows across the field in my backyard but I also have a good selection of local tech conferences and reliable fiber internet.
Still, I am eagerly awaiting the day when someone conclusively nails the obesity epidemic down to something as simple as gut dysbiosis.

That's unlikely to happen. Nutritional content of produce has gone down, people eat fewer home-cooked meals and we drive more and walk less, among other things. So it's not likely to boil down to "This one simple trick!" that can be solved with a simple product one can buy for cheap.
I think the best way to learn this stuff is from the people who did it, speaking in their own words. But watching videos takes forever, so the best way to do this is to read oral histories. The Computer History Museum has really great content-- I've read dozens of these. You can easily find them, ranking in approximate order of popularity, with the following google search:

https://www.google.com/search?q=oral+history+computer+museum...

To find more (and there are many great ones outside of the Museum), you can try a broader search:

https://www.google.com/search?q=oral+history+arpa+filetype%3...

I have found that I can read around 3-5x faster than listening to people talk, depending on the speed of the speaker (most of the people interviewed in these oral histories are quite old and can speak a bit slower), and I also retain the information much better. There is something about reading an actual conversation by someone who was there when this stuff was being invented (or literally invented it themselves) that you don't get from reading a retrospective historical account, and it makes the information stick with you more, since it's all framed in stories and personal accounts.

There's liberal and illiberal democracy, and I think for the majority of people here when democracy is mentioned, the former is the one that comes to mind not the latter.

Absolutely not. You’ll find plenty of communities in rural areas: churches, American Legion, quilting groups, hunting buddies, continuing education classes at the county extension, etc.
I don't think screen space is necessarily the right thing to optimize for. It's not the only consideration in terms of ergonomics.
> You can mark modules with "type:ignore" to make mypy ignore them.

If I added MyPy to the CI/CD checks, some coworkers would flood the code with these to not have to think about their typing. Too bad that some libraries like SQLAlchemy make this mandatory sometimes. I'd like the option to ignore these "type:ignore", but the type system is too immature and has to be overridden sometimes.
Hi. You are 1000 times smarter than the idiot author of the article. The linked article mentions none of these.
More Kremlin talking points from the account created when the war began. No surprise.

Russians invaded Ukraine, and are raping and murdering civilians - not one or two, countless. Rapes. Executions. Beatings. Murder. Theft. Destruction. Deciding which country is to blame for these barbaric atrocities is very easy for most people.

Russian people will be paying for this for a very, very, long time.

Wow. So introverts are emotional weaklings who need exercise. Wow.

Take a hike with this sanctimonious judgement.

I see extroverts as people who are so needy they need constant socialization to counteract their feelings of inadequacy and hide this by performing social dominance rituals (see BMW owners).

See how stupid that sounds? Maybe look in the mirror and think about how judgmental you're being.
This might be great! Or it might be meaningless. The only quantifying passage I see is this one:

> “Plasma donation was the most effective intervention, reducing mean serum perfluorooctane sulfonate levels by 2.9 ng/mL compared with a 1.1-ng/mL reduction with blood donation, a significant difference

But how much perfluorooctane sulfonate did the study's subjects start with? I don't care if one treatment accomplished more than another until I know that at least one of them made a difference worth making.
I enjoyed the first Saw, but to me it played out as more of a murder mystery than “torture porn” ala Hostel. It was dark in the same vein as Seven, but what made it interesting was the “whodunnit” aspect, not the horror.

Don't worry- it's ok if you look away from the road to navigate the air conditioning menu because the automatic pedestrian and obstruction sensing camera will stop the car for you!
I know some people are jumping on the idea that these "forever chemicals" just get passed onto the blood recipient, but that misses the "Regular" part. Sure, the first few donations have the higher concentrations of those chemicals, but subsequent donations have fewer forever chemicals. The more you do it, the better quality it becomes.
Recent similar-ish sort of article that I quite enjoyed, "How to Freaking Find Great Developers By Having Them Read Code"[1].

I really really appreciate having resourceful people about. People who can go hunt for answers, who can explore questions: they are the ones that make excellent fantastic programmers, and people who are fun to engage with & watch go at it. I very much agree there's a huge weakness in drilling people to see if they can come up with answers, and that this idea of seeing how they navigate & explore things is probably >50% of the real battle in sw dev life.

I’ve seen what you are describing happen several times pre covid.

I’ve been in 100% remote team since but I would be really careful with being one of the few remote resources. It’s a recipe to grind your gears alone while the team is moving on.

My only personal experience with that was being remote for a few week at a time. I always felt a disconnect settling in.
What other languages do that though? C doesn't, Java doesn't outside of particular cases. If you can trick or mislead the compiler, the runtime often has no type information at all, so you'll get, at best, a ClassCastException, and more often than not get a segfault.
> A democracy that has chosen to engage in censorship of type 2 is on its way to becoming an authoritarian regime, even if that censorship has public support in the short term.

Depends on who the political opponents are. There's a vast gulf between single-party rule, and a oligopoly of parties that censor their opponents, but not eachother. The former is seen in a place like Russia, the latter is what we have seen for decades in many Western countries. (See: The Red Scare as a great example of this.)

> I would argue that it is very difficult to prevent type 1 censorship from turning into type 2 censorship, because the party in power is always incentivized to use any tools they have to stay in power.

It's actually easy, what you need is a strong bureaucracy that maintains social norms, due to its inertia. As long as we can all shake hands and agree to treat, say, commies as a common enemy, but treat eachother as gentlemen, that sort of status quo can be maintained indefinitely.

That bureaucratic inertia is what will protect you from despotism, not the letter of the law.
> I am fine with "blocklist" instead of "blacklist"

Better hope you're not dealing with a block device or other data structure that involves units of data called blocks.
I suppose it's easy to forget to mention, when doing open source development, and the target platform is also open source. Especially if it's Linux, which is the default.

The non-LTS releases are called 'interim releases'[1]. I snagged the torrents of 22.04 yesterday, upgraded a VM from 21.10 to see how that would go, not terrible, tried a laptop, slightly bumpier, but not too bad. I have a couple of other machines to try (with nvidia GPUs...) so I may wait a bit...

The problem with radar is it can’t see up high right? Just low to the ground where the unit is?

Based on this video I’m not sure the radar would’ve had anything to catch. It seems like the plane hit the top of the car, not that the car hit the landing gear.
No, it was implying that Disney's pro LGBT stance and opposition to Florida's "Don't Say Gay" bill was tantamount to support for pedophilia. This is part of the Republican Party's general strategy to gain support for anti-LGBT legislation by fabricating a moral panic about pedophile "groomers" with the Democratic Party and LGBT community, in particular where support for trans rights is concerned.

I wonder if that 15 years away has anything to do with perception of time by people of a certain age range.

Wrt people changing what they do- yup. Given the way we soil the environment, I won’t be surprised that a few things will catch us, and also something that wasn’t foreseen in 1970. People who are frothing about lower testosterone levels and sperm counts are not frothing about chemistry that performs these lowerings, for example.
Using this on Firefox for Android causes the application icon and header bar notifications to blink as long as it's enabled. I don't think there's anything the developers could do about that though
> It's understandable why it may not be designed to check that situation, as it is not one you'd normally find in a parking lot (unless maybe a parking lot full of semi trailers).

Sounds pretty similar to the accidents involving trailers, where the top of the cars were sheared off because it didn't detect anything there.

> Neither Brown nor the car braked for a tractor-trailer, which had turned left in front of the Tesla and was crossing its path. Brown’s Tesla also went beneath the trailer and its roof was sheared off. After that crash Tesla CEO Elon Musk said the company made changes in its system so radar would play more of a role in detecting objects.

They got rid of radar, so I wonder if that's made it again more difficult to detect these scenarios.

https://www.dsm.com/corporate/sustainability/our-purpose/min... seems to be more than scientists think it could help.

They claim:

“Just a quarter teaspoon of Bovaer® per cow per day suppresses the enzyme that triggers methane production in a cow’s rumen and consistently reduces enteric methane emission by approximately 30% for dairy cows and even higher percentages (up to 90%) for beef cows. It takes effect immediately and it’s safely broken down in the cow’s normal digestive system into compounds already naturally present in the cow's stomach. As soon as the additive is not fed anymore, full methane production resumes and there are no lasting effects in the cow“

If that is correct, it also may end up being a highly profitable product for that company.

DDIO operates mostly transparently to software, with the I/O controller feeding DMAs into a slice of L3. Hardware can opt out by setting PCIe TLP header hints, and you have some system-wide configurability via MSRs, but it's not something a userspace application can take into its own hands.
nosleep.js brings firefox from ~3% cpu usage to ~25-30% cpu usage. (it's playing an invisible video)

that's a pretty steep cost to pay to simply keep a computer awake because the browser it's using doesn't support a 'stay-awake api'.
To put it another way, you're literally paying for convenience.
Agree Raleigh and the general Triangle area is a good one. Maybe surprising for most here but Maryland and Virginia is like this as well. We're more expensive but you can get 1-3 acres within an hour commute of DC and/or Baltimore with a relatively robust tech scene, especially if you're willing to work for the government. Areas like Frederick, MD even have reasonable rail commutes into DC!
Haha. Comparing business leaders to Cincinnatus and Washington is perfect manager porn. I bet someone has written a book on the parallels.

Can you name one business leader, just one, who has demonstrated no desire for power (in all its forms) and who didn't even want the position. Just one of "The best leaders" you're talking about.

It's OK although the back catalog has rotted a lot. I suspect that they repurchase a lot fewer disks that have been reported as defective for older films. I agree in general that most people dismiss this as an option--or even consider it weird--but many people I know who are much more into films than TV find this a good option. I do off-and-on myself.

Some local productions yes. They do that in every EU country too because it's in fact an EU requirement to do so. But the UK is culturally much more similar to America than the rest of Europe.

No, Urbit doesn't require an always-on connection. It does work better with an always-on connection, since its peers will send it a lot of events to process as soon it reappears after a long absence.

> This also means that all apps have full access to all your money, private info, bank accounts etc.?

If you wanted to write or install an app that had access to a hot wallet stored on your Urbit ship, for example, you could. It doesn't have access to secrets you haven't intentionally stored on your Urbit. When you say "all apps have full access" - what do you mean? For example you could write an app that is both a display case for POAPs and also spies on your private messages, but the actual app that is a display case for POAPs is written to have no way to access your messages: is this the question you were asking?
