When I worked on the USS Carl Vinson we used to discuss what it would be like in some post apocalyptic scenario where we were left on the ship. We didn't like the idea. Of course, while the ship could have power and fresh water for years, the aircraft couldn't operate long without more fuel and the people on board would run out of food pretty quickly.
Too much legal liability, someone is going to park it inside an attached garage to run house power and wind up dying to carbon monoxide poisoning.
Most people who believe the “the government sucks at everything and should be as small as possible” probably still worship the Constitution and “the forefathers” and believe it’s completely compatible.
My reply: "Government is trying to spy on every aspect of your life. There are more government employees that can spy on your children than there are child molestors in the country."

Do you want creepy gov't contractors spying on your kids?
It is insane to set market cap goals instead of share price goals. The market cap of Tesla can go up without ever benefitting shareholders.
I wish there was a way for tech to handle the underlying problem. Facebook is the big massive cherry on top of everything, but we’ve been optimizing and hacking society ever since the 24 hour news channel became a thing.

Once we crossed a few critical milestones - 24 hour news, concentration of news agencies, buyouts by large firms - the templates for the current predicament was writ.

Human minds are hackable.

Violence, sex, and bias sells. “News”, “truth” are too slippery and malleable as concepts to hold corporations to.

This will always create a race to the bottom, of the same nature as willful pollution of the environment.

Facebook is the obvious target, but so is YouTube, Twitter, Reddit. What’s horrifically worse is that this is America talking about excesses with social media it identifies.

There’s no space in most of the discussions on HN which consider the global scope of this problem - and it is a global issue.

The model of captive news channel spraying crazy fodder to build up stories and tilted facts so that crops of confused and opinionated voters can be harvested is a global phenomenon.

This isn’t a problem as easy to solve as techno utopists thought. The internet doesn’t route around censorship (as well as it did).

But it’s still a problem to solve. There has to be a way to break the attention economy while also doing justice to newsworthy content - not simply censoring Mexican gang violence news because American/UK friends of Facebook Employees come online and tell them to remove it (Custodians of the internet.)

Edit: Sure - the internet is a (Many) step changes away from the cable news era. It’s a whole different beast.

But the more I spend time looking at the problem, the more it seems to be a function of tools/ecosystems with a faster rate of revolution than our native ability to process. It’s still the Fight for attention span and ad dollars driving the race to the bottom.

Anyway, this is one of those useless rants that describes a problem (hopefully fairly) without any solution. I guess getting the problem definition right (or separated) would be a good enough start.
Same at Webex. And yes, coming up with meaningful indicators and objectives is the tricky part. But it's a work of refinement, and over time (with enough persistence), the measurements can converge to cover what really represents the experience of users.
Excuse me for not being clear.

I had a blog I ran for a while showcasing my tech projects. The main page was titled 'Failures' and it held all the attempted projects I had. Some reaching a successful deployment and the final version being posted in 'Successes'. The idea started entirely from seeing so many other blogs and social media posts with these beautifully presented codebases or finely crafted hardware. They showed the picture perfect view of those projects, but not how they got there. I wanted to do the opposite so people could actually see the faults I ran into and hopefully learn from them.

I had a lot of fun with it and learned a lot as well. There were several older projects I posted the failures of that people contacted me about to help or point out what I did wrong. Some became successes! Eventually though, I had a kid and stopped posting. The final Failure ended up being a post about the blog and a loop back to the failures section before the domain expired. I'll rebuild it someday, but I wish that kind of thing was more prominent.
Completely agree. A good IPA can be great, but I feel like they've become almost synonymous with craft beer in general. I've heard people order "the hoppiest beer you've got" because it's gotten to the point where hops == good_beer and it just rubs me the wrong way.
There are only a couple million farmers in the United States, and yet the top 5 manufacturers of pickups sell a couple million trucks every year, and the F-Series is nearly a million of those sales. I guarantee farmers are not buying a new pickup every year! (And yes, in my part of Texas a lot of people just say "pickup" instead of "pickup truck"). I'm a city dweller and there are plenty of pickups around, but I can tell you know tons of Texans in both cities and smaller towns who wouldn't even consider buying anything other than a pickup for their daily driver (and no, they're not farmers).

A lot of people around the country don't realize that lots of commercials are tailored for Texas. A big part of those are pickup commercials, saying they're built "Texas tough" or whatever.
They don't even have to be corruptible. People are fallible. Someone could just make a mistake. No bad actors needed. (Bad actors exist, and make the problem worse. But the problem exists even without bad actors.)
> China might be using AI not to "round up" Uighurs, but as an intelligence measure to prevent more terror attacks.

That is exactly what I claimed they were potentially using it for.

I acknowledge that I am very much biased against China as I live in a country within it's sphere of influence and have friends in HK.

But in any discussion of using AI for unethical purposes, China is the ur-example, as Nazi Germany is to facism: an authoritarian government with a history of tech surveillance, censorship and media control, and minority oppression, and the tech to back it up.

If they don't like that, maybe they should stop using technology to oppress their own citizens.
that's true that the calculations can get complicated pretty quickly in ecommerce, but google probably has all the data it needs (origin zip, destination zip, likely carrier(s), possibly even the weight/size of each item) to provide a pretty good estimate in most cases. they could even calculate a range for [1 item per box, all items in 1 box].

the important bit is to present it as a separate line item (with grand total) so that consumers can decide how much to trust the estimate.

that would be an even clearer shot across the bow of amazon, walmart, and the like, who provide comparison across their own platform merchants, but not across all merchants everywhere.

Typical US state laws are 15 minute paid break for every 4 hours and an unpaid 30 minute meal break for every 8 hours. The assumption is that these breaks must be scheduled for hourly workers but that “white collar, non-overtime” workers have enough flexibility to self schedule.

A good description I read of Wikipedia maths articles was that they're like the blackboard of a graduate-level class after everyone has left. All the information is there, but if you're not already familiar with the subject there's no way you'll grasp anything.
Or you know, to do the regular and never ending series of tasks result from owning a home, and which can only be completed (or far more conveniently so) by use of a truck.

In 2019 I spent 1400$ on deliveries and truck rentals. If you own a property, not having to set a 60$ delivery on a 30$ load of bark becomes a major convenience.
Just mentioning that Pinterest used to boast on their engineering blog how they designed the non-dismissable nag-screen [1] and how they increased engagement by making their landing pages more confusing [2].

Not surprised they hack their way through search.

More careful is actually a stupid advice. People make mistakes, it's unavoidable. GH makes mistakes easy to correct, which is how it should be.

> AFAIK the theory says littering does have an effect on bank robbery: If people see litter, you instill a mentality where caring for the neighbourhood is worthless. From that 'each for his' , 'dog eat dog' world view, the step to big crimes is smaller.

> Now I have no idea if the theory is correct.

The theory is correct, but the effect is smaller than proponents supposed (and seems to affect minor property crime more than violence). The poster child for the theory is the reduction in crime in NYC, but more recent analysis has shown that a larger driver was the elimination of lead from gasoline and paint.

I was a beer snob but find myself mostly drinking mexican lagers these days. It's summer and I don't want an 8% imperial stout or a brewery's mediocre first attempt at a hazy IPA
But here situation is more like:

You downloaded CBS All Access, they made you free trial member, you have no idea how much it costs. You may even don't know it costs

You started watching Picard etc, 1 week later, when new episode came, you logged in, you saw your trial has ended, subscribe to continue, lets say 20$ / month.

Apple is trying to prevent this behaviour, actually in comments one developer explaining they made similar flow.

How can it become a perfectly flat homogeneous layer, from a heating element which looks like this[1]?

It's your claim "the water at the level of the heating elements gets hotter and hotter and the water away from it gets cold" which is surprising me; water being quite a good conductor of heat, and "efficient boiler" suggesting that the tank will be insulated so not much heat is lost to the outside world, so the water away from the element should warm up by conduction from the other water faster than it gets cold from losing heat through the insulation (in my head). OK maybe I can imagine that in a fixed pressure with no room for expansion, the warm water cannot be less dense, so there can't be much convection - but then won't the heat radiate and conduct outwards in a "sphere" from the heating element including up and down, and not make any layers?

And here[2] is a video of Thunderf00t putting an infra-red thermal camera on a closed water bottle with a peltier cooler attatched to the side of it, and showing that the cold water does sink, there is some convection happening with a cold "heating element" halfway up the "tank" on one side. (But there is compressible air in the top).

Maybe it's that you don't want to run a boiler long enough for all the water to get to a uniform temperature before you can get warm water out of it, and if you don't then you risk getting super hot and cold water unmixed from "impatience" more than anything else?

It's probably because if you're low income, you likely can't afford the lower MPG or expensive things like tire replacements, and if you're upper income, you just hire people to do work that requires a pickup. I think middle-income people are in the sweet spot for trucks and SUVs where they can afford the extra costs, but can't afford someone to do manual labor for them, so they actually use the truck to haul things so they can do the work themselves.
I don't think many companies will be able to come to terms with not being able to hire FAANG-level engineers if they can't offer FAANG-level compensation. I can't remember where I once read the quip, "we only hire the best, and so does everybody else".
Good enough is just fine
They could at least include the tax in the price. That's normally fixed depending on the item category e.g. low or high tax rate. Only the US is being weird with its taxes.
On many websites it still is. But recently many smaller independent stores use the Shopify platform where shipping is the penultimate step, before billing. You have to give address, email(!), phone number(!, mandatory), etc. before getting the price. I normally just use a fake email and number to get shipping price, and then do the actual checkout in incognito. Pretty sure if you do enter your real info and don't continue with the purchase then you'll get email spam telling you to buy stuff.
I like that idea too. I just wish it didn’t involve belching fossil fuel emissions. More and more, the exhaust smells really ruin any fun or use of vehicles for me. The shelter in place period that dropped the number of cars driving by my house and thus improved air quality really underscored how much pollution there is around me.
So if my friend has one of these I can charge my Tesla on the L14-30R 240V 30A while sitting in a campsite or far off grid. Amazing if it is actually capable of that.
I would agree with this for 'new' trucks but going into my 4th year of home ownership, I bought a 3k light duty pickup. If I own it for ~2 years, it will have paid for its self in dump runs and material deliveries alone (not to mention the convenience of being able to do so on my own time).
I'm 20 years out of school, so unfortunately not very qualified to answer that question. I took a look at the 3Blue1Brown videos but it seems he focuses on subjects other than algebra.

I will say that high school math is very different than abstract algebra, and in some ways abstract algebra is simpler.

I heard a long time ago that in France they teach some abstract algebra to 10 year olds??? They are simple concepts that don't require much background knowledge.

I actually got a little bit of it in 6th grade. I remember doing some optional assignment that introduced the idea of functions as things you can operate on, rather than things you just apply to concrete data. In other words, higher order functions.

So everybody knows you have numbers and operators:

1 + 2*3 = 7

Well functions are also algebraic objects, with operators, e.g. 'o' is the function composition operator, so if you have functions f and g, f o g is also a function.

I think 20 years ago, programmers didn't think like this. These days, many programmers do, whether formally or not. JS/Python are more flexible than C or BASIC in this regard (and Haskell, Lisp, etc. even more so). So this is directly applicable to programming and it's worth a little bit of study. You probably know it, but seeing the mathematical view will make the reasoning more fluid.

It's not just functional programming either -- I don't use functional languages currently, but I use the ideas. I think that most people use inheritance poorly and I suspect that knowing algebra helps you "factor" code correctly.
How to find a startup that wants to buy a ready-made application
I sell a Macintosh app for college students who want to improve their academic success. Epiphany Workflow is about easily collect ideas, organizing ideas, and referring to ideas while writing. I'm a lousy marketeer. I'd love to sell it to a startup that would compensate me well for the 5 years it took to write it. I have no contacts in Silicon Valley. Who should I talk to?
I find it ludicrous that people use an aircraft carrier to do their daily commute. The freeway is packed to the gills with massive trucks, most of them taking a single white-collar worker to their comfy office job.

Michael Shellenberger's apology for "climate scare" [pdf]
This was originally carried by Forbes, and subsequently removed as it did not fit their editorial standards [1]. I have linked the "archived" copy.

[1] https://nationalpost.com/opinion/john-robson-forbes-falls-to...
As I just alluded to in another comment, a lot of it is marketing of a macho image, e.g. commercials in Texas are customized to tell guys how the pickup being marketed is tough enough for Texans. So plenty of people I've known buy them because they associate them as being the most appropriate thing for a man to drive, whether they ever use the truck bed or not.
Not all governments are states. Cities may also have governments, for instance, as might informal associations. In this case where it is less important that the actor is a state; it is more important that they are exercising authority and power, setting and enforcing policy.

Therefore, in this case, the term "government" is a better fit than "state".
> However, V8 creates an environment of a single thread for each of JavaScript’s execution context. The rest is kept under its control.

Maybe it's because I'm not a native speaker, but to me this sounds like they're saying the V8 creates one thread per execution context. I've been working with V8 for months now and this doesn't make any sense to me.

Can someone clarify whether I simply misunderstood the phrasing?
They are linked, but not inextricably, and the relationship is more complex than something like “the state is defined by a monopoly on power” may lead us to believe. After all, the modern state (ie one that has a monopoly on violence) is a fairly recent development: in the west, somewhere around the 1600s. And yet governments existed before then, so there has to be something more going on.

We hear something like “the state is a monopoly on violence” very frequently, but without the idea’s original limited context as part of the definition of the modern state. It helps it go unexamined that our personal experience is only with modern states, so it seems intuitively fundamental. We take it to mean that the legitimacy of the state derives from the power of the army (and police, etc). It feels like hard-eyed realism, seeing through the masks to the coercion beneath. But the real situation is reversed, and historically governments without a strong enough story of legitimacy are unable to create or sustain a monopoly on violence. (Note that violence may be an important part of that story, as with the American revolution).

To go back to Rome as an example of how this kind of “realism” can fail us, power in the republic being reduced to who could muster the most swords or the biggest mob wasn’t the true nature of government revealed, it was the end of the republic.

I’ve written way more than I intended, but I really enjoy talking about this stuff. I’m not saying that the monopoly on violence line is wrong exactly, but that taken too simply it can be misleading.

(I’m aware that the Rome example is fraught—after all it isn’t a modern state so we shouldn’t apply Weber’s terms. But for this purpose I think it works: it’s arguably the closest thing to a modern state in the pre-modern western world, and goes to my point about how power and authority are more complex than a “realistic” view that reduces it to violence.

As a consumer what you want is not important to me.

What's important to me above all is a consistent billing experience.

And no you don't understand consumers better than Apple since I spent thousands on the phone and a few dollars on your app.
