So, working with 4Km2... There are 13 million square kilometers of arible land on earth: https://en.wikipedia.org/wiki/Agricultural_land . If the virtical farm is strung up with 400 meters of 10cm layers, that makes 4000 layers. That would be 16 000 square kilometers of farming area, or a bit over 0.1% of all arible land. I think that with modern vertical farming, using a 24 hour year around light source, the farming surface can produce several times the avarage arible land production. Lets say 4 times... That would make almost 0.5% of the world farm production in just one tiny area. So it would take just 200 such constructions to replace tradtional farming entirely...
Agree. OTOH there are elements on OSX that play better with Fitt's Law than on other OSs, like the menu bar on top or the customisable hot corners (which I don't think are as common on Windows). So I guess it's difficult to come up with the perfect UI.

"Vanguard of postcapitalism" because they publish a recipe?

I'd say it was a publicity stunt from very effective brand marketers; they might as well have treated "No Logo" as an instruction manual. The Brewdog logo on the bottle matters more than the recipes to its target market, and the counterculture stance is all part of that. Brewdog's advantage over other craft brewers is branding rather than brewing.

And yes, it's also good for publicity when trying to crowdfund from "the misfits, the independents, the libertines”, perhaps because "the financial institutions of the City [which] gave rise to the bastardisation and commoditisation of beer" weren't too keen on their 115x revenue valuation. Nice of the Guardian to take those claims at face value (linked article) too.

But seriously, I'm struggling to think of anyone in the beer industry that tries to "make money out of keeping beer recipes secret", especially with most of the best-selling beers relying rather less on taste than Brewdog. Coca-cola, of course, famously emphasises their closely guarded recipe, but as with Brewdog's "open source", that's more about the corporate mythology behind the brand than any serious fear that someone might even slightly dent their brand and distribution network by making something that tastes the same rather than merely similar.

I just don't understand why you assume that the risks were not disclosed to the government. In my eyes, it's way more likely that the government decided to go ahead anyway. This was one of Saddam Hussein's prestige projects - telling him that it couldn't be done could've been fatal.

It could theoretically land anywhere on the planet in an accident situation, some freaked out country could fire up the radar jammers, would be terrible bad luck to land next to a weather radar, even if nothing bad happens it'll have Russian military aircraft loitering around the LZ and now you have the technical problem of proving every Russian aircraft radar ever made won't interfere with the landing system. I would guess if the rockets fire early the astronauts will be severely hurt (killed?) on landing so not firing early would be a priority. They didn't make it triple redundant for fun...

Also without any information its very hard to tell if this is just good old fashioned ALARA at work, or if its a real threat. On one hand a powerful source would require a smaller detector and size and mass are expensive in spacecraft. Then again the crew needs shielding from the source and they're using gammas so source intensity is also not cheap. My guess is its a combination of ALARA principle at work combined with some first responders might have radiological monitoring and that will detect it, causing a freak out unless previously warned.

The ad-blocker-blockers are annoying, and my usual response is to just go elsewhere. I'm not turning on advertising for anyone.

That being said, I'd happily pay a small ($5-10/mo) subscription if it enabled all (or a large number of) these sites again. Alledgedly my eyeballs are work millicents to advertisers: I'd like to buy all the advertising space I'm being shown at that price.

I don't think an adblock company could do it, as it would be too much like a protection racket, but surely someone could set up a subscription-based service for "ad-free content", where sites that took part got a slice of your flat subscription fee. A bit like microtransactions, except not microtransactions.
That is not how aquaponics and vertical farming work. They use solulable nutrients which are either gained through a nutrient cycle (the water flows down to a pool which has fish in it), or via mining of otherwise hard to get nutrients. Soil is not used. While the source of all these nutrients is a problem, it is comparible to the huge quantities of petrolium based fertilizers that we use today. It is bad, but what we have now is bad too...

I do like Brewdog's "Dead Pony" light IPA. Hoppy with a good bite, and light enough (3.6% abv) for an easy session with some movies. Excellent 3 to 4 % abv ales are a hallmark of English brewing.

A superior light IPA though is Tuatara's "Iti". 3.3% with a good hop bloom, plenty of bite, and not a hint of an off flavour. I suspect they increase the mineral content of the water to give it more bite. I'm drinking one right now. :)

Now a good sub 4% pilsner - that I may never find.

Ask HN: Recent censorship on HN?
I've noticed that a lot of stories regarding a certain US political figure (who I won't mention here) have been silently killed recently.

Is this HN mods enforcing policy, a rogue agent abusing their power, an organized attempt to limit discourse (as happens in Russia) or something else entirely?

In any case it's not very transparent what's occurring. What are people's thoughts?

So they were working on fixing this but the west imposed sanctions in the 90s and stopped work.

"a sky filled with orbiting trademarks or political symbols. These billboards, perpetually overhead, from which there would be no escape on earth."
I had hoped the article would talk about how code being used in the real world has political ramifications (e.g. software used to spy on people). Instead I get a potpourri from the interesting to the stupid:

- قلب: The English language bias in computing is huge, and even though e.g. Java allows for Unicode identifiers, its keywords are still in English.

Microsoft's Excel on the other hand has localized function names. Perhaps because it's meant to be used by end users who would simply not accept English names, whereas programmers are (for one reason or another) expected to know English.

I really started to notice this when reading a review of the C++ library boost.locale, where the reviewer criticized the library because it assumed software would be either written in English and then translated into other languages or translated into English and from there into other languages[1][2].

Incidentally there seems to be a really active C++ community in Japan, with a Japanese translation of Boost's documentation[3] to hardcore metaprogramming libraries such as Sprout[4].

- transCoder: Somewhat interesting as an art project. However conflating binary-based computers and gender seems far-fetched. Furthermore, there are or at least were analogue computers.

- Feminist programming language: The linked blog post is very light on content. And of course "Software engineering consists of one agent (the programmer) giving commands, and another (the computer) ... obeying them"; after all it's about telling a machine what to do so I don't have to do it myself.

- 4chan: The less said about the misogynist, racist denizens of /g/, the better.

Pumped hydro is much cheaper than batteries per KW (max storage rate) and KWh (storage capacity) is limited only by reservoir size. The roundtrip efficiency is about 80% and it's able to store for months at a time.

Heindl Energy in Germany is developing hydraulic storage, which can work even on flat ground (basically, raising a rock formation with pumped water). They've designed capacities up to 120GWh:

Spellchecking? What about innumeracy?

As you can see if you only drain your battery to 75% (meaning you only use 20% of your capacity) you get tremendously more cycle’s (more than double!) then say using 50%. So when systems are designed for energy storage you generally want your batteries to last a long time (since they’re expensive) so you want the maximum amount of cycles for them, which means that you should only discharge them 80%. As you can see this is getting quite frustrating, as now simply to power you’re off-grid system at night you need to purchase 80% more battery capacity than you actually need.

75 + 20 = 95. Okay, close enough to 100. But discharging to only 20% means you need to buy 500% the capacity, not 180%!
35% seems awfully high. From what I've read it's more like 15-20%, and a large portion of that is younger people, so the demographic for advertising on websites will probably start to shift towards older people if it hasn't already.

This is one of those "Wow that certainly feels like an exotic way to die; clearly, cranes must be more dangerous than cars in St. Louis." sort of situations.

Spoiler alert: they're not. Cranes are industrial equipment. They're getting progressively safer over time, due primarily to the general progress of technology and decreasing reliance on the most error prone component in the crane.

The most common crane-related fatality is not "crane falls over, killing operator and/or people on the ground." It is electrocution when the crane hits a power line. (c.f. OSHA or the Bureau of Labor Statistics.) This is almost invariably a consequence of human error and failure to follow well-understood safety procedures rather than "oh noes the software is so complicated these days."
It could also be people flagging.

I used to be a heavy NoScript user. I dumped it some time ago when they started doing a ton of weird stuff in the name of "security". Take a look at their list of features:

NoScript is way beyond just blocking scripts by domain at this point. They attempt to prevent things like clickjacking by subtle Javascript trickery. This broke too many web sites for me (often in infuriating and unpredictable ways) to be usable.

Pumped hydro is absolutely great, but it's an option for tremendous (grid-level) scales, and requires convenient locations (e.g. a hilltop you can "blow up" with a large stream nearby, or a standard dam with a lake or lake-able location close to its foot). It's way, way beyond the scales the article is talking about (note the picture from a health clinic in Rwanda).

Of course. Despite the title the article is only about off-grid storage, basically batteries. Though even off-grid storage can be on-grid if it's sometimes connected, as some plans for the future of plug-in hybrids call foresee.

"Vanguard of postcapitalism" because they publish a recipe?

One of the obnoxious things I've noticed about capitalism, is that its current incarnation seems to incentivize bait and switch. You develop warm fuzzy feelings about a brand, but then they start to outsource production, or sell their brand to a national brewer. This seems to happen a lot to beer, often with a change of taste and a degradation of product quality. With "open source," at least the customer can homebrew their own and do an AB test.

(Same sort of thing happens with startups, I've also noticed.)
