It doesn't tend to be what happens any more because pretty much every developed country in the world, and many underdeveloped countries, have planning and zoning frameworks that creates severe obstacles to it.

The idea that cost prevents it is a fantasy. It may prevent it in your neighbourhood, and it may prevent some of the most extreme situations, but there are plenty of areas where I live (London suburb) where factories etc. and residential neighbourhood are right next door to each other, and where the land costs are equivalent and it would not at all be a cost problem for many "objectionable" businesses to set up shop right next door to your house if zoning allowed it.

True, factories generally get quickly squeezed out of the inner cores of large cities, but residential and industrial areas often collide in the poorer parts of towns.

The example of Houston is interesting, but not that relevant in the overall scheme of things, given that Houston is very low density for a city, and low density and according reduced competition for space certainly makes it less attractive for people to fight battles over land use.

Despite that, let me quote the addendum:

>Right after I posted the above item I got an email from Nancy Sarnoff, a reporter for the Houston Chronicle, pointing out that land use remains a very live issue in Houston. Mayor Bill White, for one, is trying to stop construction of a 23-story high-rise in a neighborhood of single-family houses.

Indeed. So much so that I found it was easier just writing my own HTTP classes on top of Winsock.

But to be fair, we are talking the 90s and HTTP wasn't as ingrained into technologies as it is today. Heck, back then parameterised SQL hadn't been invented; Internet Explorer was basically the only browser (Netscape had largely been crushed and Opera was non-free); most computers still shipped DOS (if just as a bootloader); and classic ASP was a popular server side framework. So it's easy to be critical with hindsight but the whole ecosystem was still maturing.
A lot of the work is documenting and coordinating, in English like we're doing right here. (I wonder how much missing/outdated/lousy documentation we can blame on the programmers not wanting to type.)

If you type at 60wpm instead of 110, over the course of a career I'll bet that makes plenty enough difference to be worth addressing. (I recently started going over to typeracer.com and keybr.com on breaks, on that theory. We'll see.)
It makes me a little sad to hear an honest question like this because it means that people have a horribly slanted impression of the US, which is a fantastic place to visit and is generally very welcoming of visitors from other countries.

Almost 70 million people enter the USA every year - that's over 190,000 per day. We hear about 2 or 3 horrible stories and it seems like every tourist who enters the country is harassed by immigration. I totally understand the concern when one hears these stories though, it's important to keep in mind how incredibly rarely they have occurred.

I would say your chances of immigration even looking twice at your laptop are extremely small. When they want to look at any electronic device, generally the only thing they want to see is for you to turn on the power to prove that it is an actual working device and not just an empty case with explosive materials inside it. They have no interest in whatever data you have on the device.

Exceptions might be if you are involved in high profile, anti-US politics or you suspect there is some reason you would be a person of interest to the US homeland security. Or if you are entering illegally, planning to overstay your visa or doing anything which you feel you will have to lie to immigration as you enter the country. In those cases I would be concerned entering any country, not just the US.

In the rare case, they decide to see your laptop, i dont think they care if it is encrypted if you login or tell them the password.

IMO, the problem in this case is not the encryption itself, but the act of hiding something, if you try to hide somenthing, then you could be in problems.

If you login to your pc, they are not going to know if it is encrypted ;-)

> So, any improvements made to man are very much welcomed! I do feel, however, that a new format might be the best way to go

This is actually already the case. The original man(7) language (actually a set of macros for troff) has been around since the early 70s and was part of Unix since the beginning. It’s a simple language but entirely presentation‐focused, so it’s not helpful for semantic manipulation.

Modern manpages should be written in mdoc(7), another troff macro set that’s both more semantic and more expressive than man(7). mdoc(7) was first developed in 1989 for BSD and has been the standard documentation format there ever since, and is fairly common in Linux software as well (although there’s still a large contingent using the old, non‐semantic man(7) macros).

A lot of mandoc’s power comes from the semantic ability of mdoc(7) manpages, including the ability to search by flags/options/environment variables/whatever, and the ability to convert to semantic HTML5. Ingo didn’t cover so much of that in this talk, but he has in some other talks:

The author makes an error here: "But it’s problematic to price breakeven rates off of market-rate rents, because only 10 percent of the city’s housing stock is market-rate."

At the time the landlord has the decision of whether to rent out their unit or put it on Airbnb they will get market rate for it. Rent control limits future increases in rent. Illegally evicting a tenant has a similar financial pressure for market rate.

'We know almost nothing about the person who owned this ingenious knife, but perhaps he was one of those who profited from the vast expansion of Rome - he would have been wealthy to have such a real luxury item.

'Perhaps he was a traveller, who required a practical compound utensil like this on his journeys.'

Or perhaps he was a desperate knife seller, traveling from city to city trying to offload this ungodly expensive silver behemoth, where at every city he tried to explain the benefits the crowd would shout 'but I can buy a wooden toothpick for a 1/100 of a copper!', 'I already have a spatula made with olive wood!', 'I already have a bone pick to pull snails out of their shell!'.

The knife seller eventually took his own life by iron blade to the eye.
I'm pretty sure tests like these were used to exclude black voters in the US for a long time. I seem to remember them being literacy tests.

There's a good reason we should not have tests. A democratic system as we now understand it broadly means that every citizen is enfranchised. As soon as you start implementing tests, you being to interfere with the right of an individual to vote on arbitrary grounds.

While you could try to use this argument to argue for children's suffrage, I'm not sure it holds. Tests like the above have no cutoff, they can apply to someone their entire life. There are many things we don't allow children to do, but once they come of age they are (largely) free to do so. I don't know why I'm arguing against an argument I just came up with that might, hypothetically, be used as a counterargument to my original argument, but that's the internet for you.

I watched the video twice and I can't figure out what the purpose of this is.

The copy on the website suggests it's a mine clearing device but it doesn't seem you can use these to methodically clear a tract of land in order to 'reclaim' it - the paths that these things take are subject to winds and the terrain. Also there's the issue of retrieving the device to repair it and then if you can't retrieve it, there's the issue of these things littering their debris everywhere.

Then at the end of the video he says that it's a tool for local peoples to "cheaply survey the danger in their own environment". This makes more sense. If rolling this thing over a piece of land causes a detonation then you know the area around the detonation is likely to contain more mines so you can avoid that area.

Maybe someone with more insight or a better understanding can chime in.

Dude, you're going no true scotsman with bringing consumption in. Where did anyone in this thread bring in that as part of the argument other than you?

What was asked was is an approach to zero unemployment ok, and could you imagine any vectors of approach to that condition being bad, and do we have any negative societal examples at or about that state of affairs? The answer is obvious, meaning we have more data points about that situation than your proposed robo-utopia as the only convergent solution, and since we have data on that condition, states resembling it are far more probable than your proposed unitary ideal.

Idealism should always be suspect in things involving humans: economics, philosophy, ideals, political parties...anything involving large sums of humans that proposes the exact solution should always be looked at as extremely suspect. Political romanticism and One True Answers are the historical places where the body bags are. I distrust pure libertarianism, pure socialism, pure democracy, and any political philosophy that promises me A Perfect World.

I simply responded by demonstrating that opposition to rent control is taught in economics textbooks as a basic illustration of the power of the law of supply and demand.

That's probably about right. I mean, it depends how you count. I spend a lot of time at my computer, but if you only count the time spent actually physically pressing buttons that result in code then I guess that could be down to 5 minutes. The rest is spent looking at existing code, wondering how this particular thing should be wrangled together etc. I mean, I've spent a semester writing about 2k lines of code so things go slow. Then again it's a compiler for my own language, which together with me not being a great student probably means this is abnormally slow.

Even much of the domestic food you eat in the US is quite old.

The average supermarket apple in the US is over a year old.[1] According to Martin Lindstrom in "Brandwashed" it's an average of 14 months old.

Food preservation is great and allows us to eat domestic apples year-round, but taste and texture suffers immensely.

I said that his assertion that rent control is "widely considered a failure everywhere it has been implemented" is wrong. It's "widely considered" a failure by rich people who seek more rent (duh), and by economists of certain ideologies. People who rent in rent-controlled cities are largely happy with the outcome, or rent control wouldn't exist.

You posted a link that says that a whole bunch of polled economists don't like rent caps. That's unsurprising, but rent caps != rent control. I'm not aware of any city that has capped rents, because that would be stupid. San Francisco does not cap rents.

The worst case is rather nasty though: the rendering of a large area uninhabitable and unusable for agriculture.

There is no "away", as people like to say about rubbish.
By most accounts, the majority of mathematics papers and textbooks feature "informal" proofs, as opposed to "formal" proofs. Rather than work in a clearly-defined formal system where every inference step is justified by some axiom, the goal of most mathematical work is to produce human-readable arguments aimed at other mathematicians, arguments that could "in theory" be turned into formal proofs, but are not ultimately formal proofs themselves. Granted, even these "informal" proofs are more rigorous and detailed than virtually any argument seen outside of mathematics.

Furthermore, these informal proofs are written in standard, linear prose (interspersed with copious mathematical terms and symbols of course) because again the focus is on communicating the ideas, not on justifying every individual step.
South Africa's electricity supply crisis has nothing whatsoever to do with the West or colonialism, it's entirely about bad governance and a lack of long-term planning.

The country has around 40GW of installed capacity, dating from over-investment before 1994, but the state opted to both not build new stations and not carry out any maintenance on the existing stations for years so about 10GW is now offline and unusable. Hence the frequent power outages.

That reminds me of this quote from a fantasy novel:

> "At Teidez's interment, he never missed a chance to pass some little comment on Iselle to any lord or provincar in earshot. If she wept, wasn't it too extravagant; if she laughed, how odd that she should do so at her brother's funeral; if she spoke, he whispered that she was frenetic; if she fell silent, wasn't she grown strangely gloomy? And you could just watch men begin to see what he told them they were seeing, whether it was there or not. Toward the end of his visit there, he even said such things in her hearing, to see if he could frighten and enrage her, and then accuse her of becoming an unbalanced virago."

Ask HN: Audio stream loyalties payment services besides StreamLicensing?
Hi,

At one point, I had set up an icecast server & was streaming my privately-owned CD collection via my Wordpress site. I chose StreamLicensing.com to pay my loyalties, for a monthly payment, but had to cancel my subscription & delete my stream b/c I couldn't afford the monthly fee.

My music is primarily techno mixes, and I'm under the impression that if my stream's content were fingerprinted such that I'd only owe loyalties on content which demanded they be paid, that I'd end up owing fees far less than the amount I was paying StreamLicensing per month.

What services are available other than StreamLicensing, that might be able to lower my costs?

Thanks,

All of California is exploiting cheap water - normally this isn't a problem, there's more than enough to go around - now, not so much. (it's not subsidized, the costs to bring it to the users are pretty evenly passed along to the users of the water)

Los Angeles relies on water brought from the Owens valley, the California water project, and the Colorado river, San Francisco from water brought from Hetch Hetchy, and so on, really, the entire west, and the settlement of the American West is frequently a story of water.

Most large cities across the world import water, NYC, Rome, London, etc - agriculture is no exception to this trend.
Why "comparable to rebar"? Are you talking about surface finish, or material properties (which I, at least, am more interested in)?

I'm glad to see someone talking about using the lower-level web libraries in Racket. The high-level continuation-based ones are ridiculously unsuitable for actual web programming (they store full state on the server at all times, and the URL gives you full access to the session, among other issues), but the lower-level ones actually look pretty clean and modern. And yet all the documentation keeps talking about the continuation stuff, bizarrely.
