Isn't that a type of homogeneity?

Surely it helps a great deal though.
The opposite is more likely.

Updating baseband firmware is like updating your network router; it's likely to briefly interrupt the connection.

They're applied by the operating system, so the OS is going to choose to automatically do them when the phone is locked with idle network traffic. It's probably more of a sign the phone is not in use.
Under normal conditions: no. But a hacked phone may fake going offline and still be connected.

The only way to turn off a phone for sure is to remove the battery.

My hunch – both the Red Tribe and the Blue Tribe, for whatever reason, identify “America” with the Red Tribe. Ask people for typically “American” things, and you end up with a very Red list of characteristics – guns, religion, barbecues, American football, NASCAR, cowboys, SUVs, unrestrained capitalism.

That means the Red Tribe feels intensely patriotic about “their” country, and the Blue Tribe feels like they’re living in fortified enclaves deep in hostile territory.

Here is a popular piece published on a major media site called :America: A Big, Fat, Stupid Nation". Another: "America: A Bunch Of Spoiled, Whiny Brats". "Americans are ignorant, scientifically illiterate religious fanatics whose “patriotism” is actually just narcissism." "You Will Be Shocked At How Ignorant Americans Are, and we should Blame The Childish, Ignorant American People."

Needless to say, every single one of these articles was written by an American and read almost entirely by Americans. Those Americans very likely enjoyed the articles very much and did not feel the least bit insulted.

And look at the sources. HuffPo, Salon, Slate. Might those have anything in common?

On both sides, “American” can be either a normal demonym, or a code word for a member of the Red Tribe.

END QUOTE

In my experience left leaning (or really blue tribe, read the article for the difference) American travelers do the same thing to try to prove to foreigners that they "aren't the bad type of Americans" (ie, the right/red tribe) that they perceive that foreigners dislike (whereas most foreigners I encounter take for granted that all kinds of people come from all places and don't judge that much by nationality), the irony being that the foreigners don't usually ever say all that much negative about the US and it's the American's who are trying to distance themselves who end up being the ones who vocally dislike America (but really just the people they think are ignorant)
I had a look at the linked spread sheet¹ containing all the framework questions.

It's actually great advice for solving any programming problem — not only in case of a whiteboard interview.

Not that you need to write down everything explicitly for any problem. But you should in any case think through all of the mentioned things at least.

The other thing I've noticed is that a strong type-system will from the get go force you to describe exactly—down to the details—at least 80% of that stuff. Refinement types for example let you constrain further types with a lot of inhabitants. But even the usual things like optional or, for the contrast, non-empty types can help greatly. With some formal verification capabilities on top you could likely even codify more than 90% of the things mentioned in that spread sheet. Add some meaningfull comments with the reminder of the answers and you'll get almost perfect code in my opinion.

I would bet bug count in software overall would go down by more than 90% — if only all code would look like that in reality…

Can we bring back webrings and stumble-y things while we are at it?
That's just nonsense and completely misses the point of accounting. If businesses are imposing unacceptable externalities on society then those need to be priced in using taxes.
No, they're not. You can try to split hairs and talk about how the rates are just lower, sure, but vaccinated people are not taking up beds (like the unvaccinated are).

Please take a look at the rest of the thread for sources that vaccinated individuals spread covid at lower rates than the unvaccinated.

Please stop spreading antivax FUD.
It's definitely in a weird place. People used to do fast food, expecting not much, for not much money. But plenty of premium options exist. A burger from a steakhouse is like 7 bucks. My local food truck, 6 bucks. And that dude makes it fresh in front of you, and puts tiny fries on it(Venezuelan style, apparently).

That Wendy's charges 5.19 for a single is almost an insult, when 80 cents gets you something worlds better.

So does fast food just disappear? It simply doesn't compete with more premium offerings today. Or do they compete with the steakhouse/foodtruck, and eliminate the fast/cheap aspects?
Look up "device attestation". It basically let's software verify its talking to a hardware TPM made by a whitelisted manufacturer rather than an emulated TPM.

All kinds of DRM schemes want to do that to be sure they can't be run in an emulator.
This article is much better than I expected it to be.

It communicates the changes that are happening with low-wage workers more vividly than the many articles on the statistics. It's hard not to feel moved by the stories of the people in the article and hard not to cheer for them. Remarkable reporting.
Wolfram himself is working on physics and fulfilling a life long dream. (He was just on Lex’s podcast.) Say what you will about his contributions but it is hard to argue he hasn’t been enormously successful at achieving his goals of developing an entire cathedral of work he can use for his own intellectual persuits.
It's complicated. For people you have an obligation to, like relatives, superiors or customers at work, you have to go out of your way to be polite and helpful. But if you don't have that obligation, you don't need to do anything.

Foreigners occupy a weird spot in this hierarchy as "guests" to all Japan in a sense, so people often feel an obligation to help them, much more so than they would to a random Japanese person in the same situation.

Monetary value reflects demand, but demand does not always reflect utility or goodness. There is a demand for atrocity.

The construction “NFTs are highly priced, thus they are desired, thus they are good” is full of holes. If I have a phobia of spiders, and a corresponding desire to eradicate them, does it follow that eradicating spiders is good? If I got my wish, I and the rest of the world would be worse off for it, but my desire exists none the less.
I've had the log out problem, but it eventually went away.
"good intentions are a road to hell" is false with some very basic thought experiments. For example, read the U.S. consitution, specifically on its ammendments. Freedom of speech is a good intention. Individual autonomy at all is a "good intention" just as much as fascism is. Everyone can have conflicting good intentions, therefore it's a poor argument that doesn't address the merits.

You could apply that argument to other unhealth habits. Heart Disease is one of the most deadly and debilitating problems in the U.S., which should be met with significant tax on sugary products. The health costs are astronomical and deadly. However you're strawmanning my argument, there is a weight to when someone deserves regulation and does not. Many "unhealthy habits" do not rise to a great enough problem or have other benefits. For example, sitting at the computer is an "unhealthy habit", and it can be quite lucrative in certain work.

Dystopia is when a private company advertises to children that they should take a substance that company designed to be heavily addictive and harmful to themselves and everyone around them.

Social control is an natural part of humans and has always existed. Government regulations, when done in certain methods, demonstrably work. Other times, they do not.
No-code NFT storefront Builder
Hey HN

My friend and I are building a no-code NFT storefront builder for communities.

We saw how technically challenging it can be for a lot of people to mint out an NFT.

The only alternative is getting through OpenSea, which is non-customizable and takes enormous platform fees.

Attached is a quick demo and here's the landing page: https://typedream.site/nftcommunity

What do you think?
There is nothing technically stop the carrier putting more memory on the SIM card.

> Wind turbines generate 690v three phase. It isn't stepped down until it gets to a substation near the consumer.

Large utility-scale wind turbines do not have power leaving them at 690V. It's many kilovolts. If they put out 690V, just for the sake of example a 2MW turbine would be generating ~3,000A.

> The power needed onsite (lights, control systems, energy to start the blades spinning, etc)

Self-motoring is only necessary on stall-regulated turbines. Most large utility-scale turbines are pitch-regulated.

Here's video of a turbine starting up, showing its control panel with power in/out indicated:

https://www.youtube.com/watch?v=3bYZ14eebFw

> usually comes from a natural gas generator or a direct feed from a fossil fuel plant if one is nearby

That is not how electrical grids work.

If a wind generator is not generating power and goes online, the power for its control systems comes from the grid, which encompasses all the electrical generation devices attached to said grid. Power for control systems could be coming from other wind turbines, solar, hydro, stored energy, nuclear, whatever.

> Due to circular dependencies, you can't power them off the energy they generate.

If the generators are connected to the grid and generating power, all the control systems, lighting, whatever - is connected to the same grid. If it's not generating power, all those systems are still connected to the grid.
It constantly fails on everything.

I even thought it would an interesting project to write a overlay to get it working.

Even Google can do this -

How much simpler can you get?

Anything useful to an adult doing napkin math (or a child) it fails at.

I'm sure it can do integrals and complex math but since it can't even get you started, you'll already using something else.
Unfortunately, that economic trick can't be repeated forever. We've simply run out of land that is within commutable distance, and our governments are collapsing under the lifecycle cost of infrastructure for ever lower densities.

I read an interesting article that framed the new laws around loosening single family zoning in California as allowing a new type of homesteading. Basically, the zoning regulations have forced homeowners to more or less get value only out of the house they actually live in. Actually homesteading with a garden in your backyard in 2021, the way American homesteads used to be small farms, would not really make any sort of significant income.

The argument was that people can now choose to use what was previously more or less legally mandated unproductive[1] land, your backyard and front yard, to be converted into more housing, which could be rented out as a source of income.
For what it's worth, in Japan itself, Kyoto people have a reputation for being snobbish, standoffish and unhelpful, and if anything that has gotten worse recently with the sheer amount of tourists inundating the city (until COVID, anyway).

But yes, foreigners are a dime a dozen in Tokyo so nobody really cares. If you go out to inaka (countryside), you get a lot more attention.

I see. That also explains why lots of software companies cannot define 'Linux support' and cannot support the latest version of 'every' Linux distro, 100% of the time.

A fundamental issue in the Linux desktop ecosystem and a line has to be drawn which guarantees a complaining user on an exotic distro or a fork of another one.

As for Windows, and Mac they are supported on the latest versions 100% of the time.
If it's only AAA games, you should be able to get by on Linux _quite_ well these days, if that strikes your fancy better than Windows.

I actually can't remember the last game I tried that didn't work. You may want to look up the compatability of the last few you played though just to make sure your genre(s) won't get a lot worse milage than what I play.
Exhibit A, your honor.
You cannot buy the battery from Apple or an authorized reseller. You can pay for them to replace it themselves, but they won't sell you the part.
Comparing any rail service with France or Japan is futile. Nobody compares with them, least of all the US. For Tokyo to Hiroshima you have multiple departure times every day, and your choices of speed at each time include slow, reasonable, fast, really fast, and really, really fast. It's rather breathtaking, even if you're from a country with good train service.
It’s probably a lot more than 3.

As an EE, plenty of chips you can get are built-in computers. You’re not going to write code that you make your users run (what a support nightmare!). You build your chip and provide an API.

And as a user, do you really want to figure how to run someone else’s code? Or do you just want a self contained unit that you slap onto your board that you just control via API?

Think of chips as microservices.
If I'm Goldin, there is absolutely no way I'd be openly promoting the fact that Deshaun Watson invested in us.
Fact check needed, but doesn't 'corn' mean '[primary]staple', officially? So what Americans call 'corn' is technically Maize, according to that view. Somewhere else the 'corn' could be rice -- again on that view.

That's correct. "Co" + "didact", learning together. (I am one of the founders, though not the person who suggested this name.)
That's not irrational in the sense of there lacking inherent reasoning or rationalization, it's just a poor deduction. If you mean that rational agents are incapable of flawed reasoning, then I agree that humans are somewhat irrational (and further that no human could ever be rational).

I suppose my biggest gripe is this: how do you construct a notion of rationality which allows for some people to be perfectly rational sometimes, imperfectly rational at other times, and others to be rational never, while allowing for real flaws in reasoning and the absence of perfect information? (this is, to me, a rough sketch of some necessary/sufficient conditions)
Both neoliberalism and neoconservatism have interest in spreading "liberal democracy". Neolibs alone probably wouldn't invade for it, but they certainly won't resist the neocons doing so.
Also, if you use the Firefox search bar only the first 20 chars are sent to google, so longer calculations are truncated before they're calculated and wrong answers come back with no warning. Not a Google problem per se but a risk of using Google to calculate still.
I once had a coworker message me out of the blue asking if I'd be available to chat later that day. I said sure, thinking he'd follow up with the topic of the chat, but he just sent me a non-descriptive calendar invite. I didn't want to sound paranoid so I didn't ask (I should have), but in my head I was racking my brain for any possible reason he could want to talk to me one-on-one. I was pretty new to the company at the time so I was worried I'd done something wrong, but I couldn't think of anything so serious that he would need to schedule a chat about it and also he wasn't really my superior so that would have been really strange. I decided to just try not to worry about it.

In the end, it turned out he was leaving the company and wanted to tell his fellow engineers one by one. It was sweet and the secretiveness made sense in that context, but it did leave me a bit spooked.

Conversely, during a one-on-one my supervisor ended our small talk with, "So I have something a bit more serious that I want to talk about..." immediately followed by, "--it's nothing bad!" So luckily he was a bit better about not being spooky. Turned out they were promoting me.
I worked there first job as well. 1995/1996. Tough job, but not too bad. I worked up front running registers and helped in the kitchen as well. I was 6’1/6’2” back then and climbed in the play place tunnels to clean up kid shit and vomit, often smeared everywhere in there. Worked on an Interstate. One night 30 minutes before closing the Tampa Bay Buccaneers rolled in and ordered an insane amount of food. No one was even annoyed. It was impressive how much food they ordered. Honestly, I don’t remember too many issues or “Karen” types back then. The occasional upset customer over an order mistake or something. I always went home smelling like McGrease. It was not an easy job, but I suppose I was treated alright. I’ll take my desk job any day.
I must say it's worth mentioning that as you build up a library of knowledge and experience in your mind, learning new things become more transitional than exploratory. Picture spoken languages for example. At first it's daunting and most languages have their quirks but overall after a few you find your marks easily.

The effort becomes a memory concern where cheat sheets are how you transition or learn quickly into a new space.

I'm a polyglot in software development. I can work with most tech stack within 2-3 weeks and be efficient within 3-6 months, idiomatic within a year maximum. A big part of that is due to relatability between spaces. Every toilet has a flushing button and every kitchen has a sink and every language had a form of exposing positive or negative response.

My advice is always throw yourself in and swim. Find whatever swimlane or swimming aid available and move forward.

One caveat is learning spaces that are constantly shifting. For example, Swift. What a mess. Look up anything in that language and find 5 ways to do something, 3 expired, 1 manageable and 1 undocumented that works. It's sad but know that that's the outlier, not the average!
Good point! I'm going to include a sample review so the deliverables will feel more tangible.

And thanks for your assessment! It's certainly nice to hear that some things I aimed for landed.
There is also the option to bypass the lock screen and only go to the Notification Center. On iOS this is called "deliver quietly".
While APL dialects are very nice for this sort of thing, they generally don't understand units of measure or know about physical constants; you have to put those into them yourself. Here are some of my recent units(1) queries:

I agree, when you study the classics like Greek philosophy, you se the same problems we have today, because socially we have not evolved even though materially there has been significant advances.

I think even having a working knowledge of common algorithms and data-structures is insufficient preparation for these. They often call for incredibly esoteric algos/datastructures or test for patterns incredibly uncommon in industry, i.e dynamic programming.

I would say even if you had a good background in how to implement a proper production ready database, i.e b+trees, bloom filters, journaling, etc. This while certainly enough to do the job of building a database would be insufficient to pass the interview to build a database.

Which to me seems like the system is broken.
> The net protein utilization is profoundly affected by the limiting amino acid content—the essential amino acid found in the smallest quantity in the foodstuff. It is therefore a good idea to mix foodstuffs that have different weaknesses in their essential amino acid distributions.

> The limiting amino acid for wheat is lysine.

From what I gather, you still can process all of the protein from wheat if you get lysine from somewhere else:

> A vegetarian or low animal protein diet can be adequate for protein, including lysine, if it includes both cereal grains and legumes.

This also means that any statements about protein utilization from compound meals are more-or-less bogus if done without calculating the different amino acids.

> People aren't going to pay 8 dollars for a big mac

I think people used to say this about Starbucks, where you might pay close to $8 for just the drink.

Fast food can probably save itself by going premium (as Starbucks did, although I don’t know if they are still considered premium) and raising prices and quality. McDonald’s has made that play in the past with the pivot to McCafé and the nicer restaurant design that is now predominant.

What may have to go away is the idea of fast food as something that is attainable for just about everyone. I remember when I was much younger and McDonald’s was a treat - we didn’t have much spare money but my parents could make McDonald’s happen occasionally.

Nowadays I’m totally price insensitive and happy to pay for DoorDash to deliver McDonald’s and tip handsomely. The people who don’t have software jobs or a similar tier probably can’t. Big business will be fine regardless, and if they can’t make it work, the leadership is not worthy of their overpriced MBAs.

I worry about the lower classes though. An under appreciated (for the wealthy HN reader) aspect of the relative success of American development is the broad accessibility of luxuries to the masses. Even the poor masses. If you (dear reader) don’t recognize a fast food meal as a luxury, you are blind to the real consequences of what is unfolding. I understand the desire to cater to labor, but ultimately there are far more consumers than laborers (by definition - all human laborers are also consumers). The grand economic experiment of yanking away the _one_ aspect of the American project (abundance) that has until now been continuing to succeed will have consequences. Not for me, but for the people you think of when you think of labor.
