I am not sure I understand. Let me rephrase your question to me as I understand it now:

On one hand, there is a regular farm with farm labour and natural sun light. A traditional calendar picture farm. A tractor, some workers, rows of crops, red barn etc.

On the other hand, there is an automated indoor farm with artificial lights.

Are these the two scenarios that are being compared?

I agree that indoor farming will likely seem more profitable even though lighting costs money.

But it doesn’t happen that way because of

1. economies of scale.

2. While indoor farming is being tinkered around with..someone still has to keep supplying lettuce to the Walmarts and Whole Foods and Safeway’s and Kroger’s and restaurants and consumers.

3. Right now, the advantage of outdoor lettuce farming is legacy. California lettuce companies have been doing it for so long that they have perfected it to an art form.

But regulations are strangling and water is disappearing. Soon labour too. And it’s getging expensive.

They do the best they can. They give medical, 15-27/hour including benefits, breaks, overtime and some even provide housing. But it’s not going to be sustainable because the public still wants cheap food.

Even if indoor systems are automated, the jury is still out there if it would be profitable. Also..indoor plant specialists would want 60-120k. The Joses and Eduardos and Marias employed in the field demand much less.

Make of this what you may...I am just throwing light on current ground reality. I have NO solutions or recommendations. These are bigger problems.

I do know that food security is important. Local food supply is crucial for this. Food should be reasonably priced for everyone. Farming should be financially viable and sustainable for young farmers to keep doing what they do best.

My solution is small farm robotics. Outdoors. Because I am not an indoor farmer. I only read about it. Perhaps there are other ways to deal with it but I am not equipped to comment more. I understand large scale production but I haven’t worked in it. Everyone is an employee in a corporate farm. I am a farm owner and a farm worker in my farm. So it’s worlds apart.

> the ones you've listed are infamous and hardly overlooked

You think? Here's my experience (I went to school in Germany).

> Annihilation of local tribes by colonisers

Saw some TV documentaries on it. Not mentioned in history class.

> forced opium enslavement of China

Heard about it on a history podcast. Not mentioned in any sort of mainstream media or curriculums.

> dividing up China between France/Britain/Japan

Hearing about this for the first time now.

> pestilence from European cattle annihilating 2/3 of inland african people via starvation

Hearing about this for the first time now.

> the policy of the Holy Roman Emperor and The Pope to keep german states at war with italian states

This rings a bell, but only very distantly. So maybe I've heard about that somewhere, but no idea where.

> emperor Chin executing the whole village where any crime at all occurred

Who's emperor Chin?

> The Spanish Inquisition

Saw some TV documentaries on it. Not mentioned in history class.

> [the last three bulletpoints about communist dictatorships]

The gulags were mentioned in history class. Nothing about Mao or the Khmer Rouge. I saw some documentaries about Mao on TV, though.

In general, history education in school was infuriatingly superficial wrt the 20th century. The curriculum was basically chronological, starting with the antique Egyptian empire in 5th grade and ending with contemporary history in the 10th grade. (Then in 11th through 13th grade, the same structure, but condensed into three years.)

The obvious issue with this structure is that you always run out of time at the end of the curriculum, so you have to rush through the most recent parts of history, which IMO ought to be given the strongest emphasis of all periods.

This is one of the things that convinced me as a teenager that our entire healthcare system is fucked. My mom died of an aggressive form of cancer after ONLY 15 months of treatment.

My dad, making an upper middle class wage in a low cost of living area with good insurance, was almost bankrupt by the end of it. He had to borrow money from his siblings to bury my mother. On top of that, he is the kind of guy that makes /r/personalfinance proud. If someone like him that shuns most luxuries and makes a top 10% salary in the US can have his bank account decimated in under 2 years, I shudder to think about the 90% of people that make less than him and have less self-control.

As a society (US) we HAVE to solve this problem. Our healthcare system is a disaster from top to bottom.
On the other hand, those came out in the US when I was around 20 years old and I remembered visiting my folks during the summer and hanging out with my younger half-brother. He was maybe preschool age and watched plenty of cartoons and other kids shows.

Compared to most of them, Pokemon was actually pretty decent. It had a (very basic, but still...) storyline about kids going off on kid adventures and meeting lots of weird cartoon animals. I mean, sure there was the whole "catch wild animals and train them to fight each other" thing but it wasn't really any more violent than the GI Joe or He-Man or Voltron shows I watched as a kid.

Going back to those, the only real common negative thread is how they were basically ads for toys and games. Taken outside of that, I saw Pokemon as a halfway decent "starter anime" that was loads better than some of the live-action cartoons of the time (Power Rangers and its knockoffs were just awful).
It's great when it works though; I thought I was running into a race condition once but wasn't sure (new to the language), and having something verify it was indeed a race condition was really awesome.
I think if you’ve taken 1 or 2 economy flights, you should know what it’s like. They’re all the same, and for most people, they just don’t have the disposable income to spend more on a better flight experience, or they would rather spend it on something else.

>I had a Datasette. It was expensive at the time, and it was amazing that it worked at all.

It was expensive in the beginning, but later on it was cheap, at least in comparison to the 1541 floppy disk drive which was in the same price region as the C64 itself.

If you look at the hardware this is not surprising. The Datasette was basically a slightly modified cassette player. The Atari "Datasette" (410 Program Recorder) even looked like the typical portable cassette player of the time and could be used like one. It could play audio cassettes through an internal speaker. The 1541 and the 1541 II on the other hand were little 8-bit computers in their own right. They contained a 6502 (almost the same CPU as the C64) and there was software to use the floppy CPU as a co-processor.

>You could put one of the C64 tapes into your boom box and play them, and hear a series of unpleasant screeches and whoops.

You could not only play them, you could conveniently copy them with your boom box. This was the way software was pirated back then. A dual deck boom box with high speed dubbing - much faster than copying with the computer.

In the Netherlands there were also experiments where software was sent on FM radio. You recorded it on a audio cassette which you could then use in your Datasette.

While most people used regular 60 minutes audio cassettes for software there existed special 7 minute cassettes for some time. This saved you from a lot of winding and rewinding when you missed the program start.

Good times, good times...
The US foreign policy for the Americas in the early 20th century is something that tends to be thoroughly ignored.

Treatment of indigenous peoples around the world is also another big blinders, although the US has done one of the better jobs of being forthright about poor treatment (compared to Canada, say).
There would be no blow.

China (or the NSA) hacking into something is non-news. Everybody expects that, especially since Snowden. It's their job, and the news would be them failing to do it.
Champagne is literally the name of the area where the product comes from. It makes perfect sense that anything that doesn't come from the region Champagne, isn't champagne... Call it sparkling wine, it's fine, but not champagne. And it applies to most local products. Camembert? Comes from a specific town, which is called Camembert. Beaujolais? The name of the province. And the list goes on. It doesn't sound "absolutely ridiculous" to me.
The US has placed camera in Xerox copy machines that were used in the USSR embassy before, so it's not surprising at all for hardware hacks. w

The difference in this case is definitely scale.
Remarks by Vice President Pence on the Administration’s Policy Toward China
I'm trying to understand what blattimwind is saying here, but this might be a case where deep understanding has suffered from a badly worded post.

Just guessing here, by pulling apart what little is in there:

* Total power usage has a big fixed parts, e.g. screen power usage going up linear with brightness and screen size. Or RAM power usage goes up linearly per bit just to keep the memory intact. So Let's assume OP talks about only the 'clocked' components, like CPUs and busses.

* I did hear for single core CPUs how the power usage arose with the square of the CPU speed, unless offset by die shrinking or technological advances. This was one of nature's walls hit by the Pentium IV. Can't find a good reference atm, but here http://www.tomshardware.co.uk/answers/id-3025075/higher-cloc... is a page with the first graph looking square-ish being what happens with power usage when clock goes up on the same machine.

* And throughput is linear with clock speed, if nothing else changes. If you double your clock, you double your throughput just by moving more data over the same bus. So the third line of OP is consistent with this: 1/5 of the throughput is reachable with 1/5th of the clock, thus 1/25 of the power.

* First line might compare 2 ways to raise the throughput: Either rise the speed of 1 core or add more cores. When you rise the speed of 1 core, power goes with the square of this rise. When you add more cores, power goes linear with these cores, assuming your interconnect is free.

* Second line 'between square and m^n' needs some interpreting. It might make sense when for a square n=2, and m measures frequency/throughput/core count/... . I assume he says the real relation might be power usage = throughput^2.3 for example

* When you have m cores, and each is interconnected to its m-1 brothers, you have m*(m-1) interconnect elements using power. This is again a square law. You can get around this by not connecting everything to everything, but this will cost you in data throughput - There will be bottlenecks.

Thats what i can make from it.
Would you drive a Chinese car that looked like a German car?

When you straight copy a design, it signals that you don't give a shit about what you're doing. Safety? Security? Quality? Fuck it.
In another part of this thread[0], Bartweiss says that Raven's Advanced Matrices is valid up until about 150 IQ. So I was close. And my bigger point is that, though the measurement lacks precision at that level, if you lined up a bunch of 150 IQ people and a bunch of 160 IQ people, there are probably some aggregate group differences. Anecdotally, I've spent a lot of time around really smart people. There are gradations even at the top (just as there are in all other areas of talent; there's only one Lebron James, after all)

Quant Investor Cliff Asness Hasn’t Smashed His Screen This Year Yet
Was that a highly detailed front page investigative story? Because I’m specifically talking about those. For other cases, they are wrong quite frequently, some of the nonopinion articles on Bloomberg are often a few rungs above college journalism reporting. All elite papers are the same in that regard. The Nytimes just a few weeks ago they had a story that Nikki Haley spent tens of thousands of dollars on curtains and a possible corruption scandal which was easily disproven hours later. Those are usually junior journalists working on it alone, sometimes creating a story rather than reporting on one and fitting all the facts to match a singular narrative. These ones I’m talking about are different. They have a much higher level of checks and due dillegence.

Edit: I absolutely could be wrong and things could be disproven in this, but just in my experience highly detailed articles like this are usually right on the money or close but just like everything in the world, can’t say anything with certainty.
You're never going to get a perfect guarantee. The airlines have to have the ability to swap aircraft at the last minute and that may mean delivering different pitch than originally shown.

Do passengers want the extra inch or do they want to arrive on time? I'm betting it's the latter.

Sure. My food cost per day varies between 6 and 12 dollars, on average ending up at 8. I take advantage of end-of-day sales, packaged food discounts, etc. In short, I'm able to time my food purchases so that I eat one to two meals a day in a 4 hour window between 4 and 8pm, which gives me the benefits of intermittent fasting and also provides me with caloric restriction on the basis of availability. During the week, my two meal cost is just under $10. On the weekend, most of the overstock opportunities are gone, so instead I visit a local ethnic grill which has full platters for under $10. If I get fancy and want more exotic meat, the cost goes up to $12.

Most of the foodstuffs offered on discount end up being fresh prepared salads w/ salmon, whole chicken, roasted vegetables, etc. The time cost for preparing all of these properly at home is substantial.

Given that I don't buy groceries anymore, I don't have food available at home to snack on. If I want food I need to prepare rice or some other primary grain. These dishes have a significant lag-time between the impulse to eat and the dish's completion, so this prompts me to ask "am I really hungry or just bored with what I'm doing?". Often, I'm bored. I'll pop open a new book or change up what I'm doing instead of downing 400cals. Even if I do give in and prepare a bit extra, I'm still under my daily limit by a substantial amount.

The alternative, grocerywise, costs me approximately the same amount when accounting for spoilage and time. I love cooking, but the time cost associated with shopping alone (let alone preparation) puts the expected monthly cost of preparing food at home over 11$/day for me.

Accordingly, it doesn't make sense for me to shop for groceries. I'll keep a few vegetables (cucumbers, cabbage, etc.) or soups available for moments when I'm in a pinch (sick/extra hungry/very active days etc), but otherwise I just wait.

I'll likely look at adding pure-protein home-cooked options when I start hitting the gym hard in a few months, but I've bulk purchased fish and steaks from importers and local meat packers respectively at 1/3rd of their normal retail price anyways, so I'm good to go on that front.
Just imagine for a second if someone was advocating on HN for the use of a web framework that has knowingly allowed itself to be compromised to steal passwords because it was cheaper to use.

How about a compromise? If any of your customers are a victim of a crime because you continued to use a shady but cheap vendor after seeing them trying to slip past tampered hardware, your company is held fiscally and criminally responsible.
They’re all the same

Right, and if any of them are different/better, people mostly aren't aware of it. So why would you shell out? If I knew a particular carrier consistently offered an extra four inches of legroom and consistently cost five percent more or whatever, I'd fly that carrier every time. But it's not even consistent within a carrier.

Business/first class of course has great leg room on every carrier, but costs like five hundred percent more.
I've been thinking about computer energy use for a while now, although I'm no expert in the area. Here's a comparison of nJ per instruction from my notes:

| | nJ/insn |
| MSP430 | 0.9 |
| PIC24 | 2? |
| 1990s StrongARM | 1 |
| LPC1110 | 0.3 |
| Pentium | 10 |
| STM32L0 | 0.23 |
| Ickes DSP 2008 | 0.01 |
| Subliminal 2006 | 0.0026 |

MSP430, PIC24: http://www.ti.com/general/docs/lit/getliterature.tsp?baseLit...

StrongARM: http://www.researchgate.net/profile/Kristofer_Pister/publica...

LPC1110: http://www.nxp.com/documents/data_sheet/LPC111X.pdf

Pentium: http://www.newscientist.com/blog/technology/2006/08/explodin...

Ickes DSP 2008: http://www-mtl.mit.edu/researchgroups/icsystems/pubs/confere...

Subliminal 2006: http://web.eecs.umich.edu/~taustin/papers/VLSI06-sublim.pdf 2009: https://web.eecs.umich.edu/~taustin/papers/TVLSI09-sublimina...

This is sort of comparing apples to oranges. The Pentium (all of them) uses wildly varying amounts of power for different instructions, and has 32-bit or 64-bit instructions, with hardware floating point. The STM32L0, LPC1110, and StrongARM are 32-bit processors with no hardware floating point. The MSP430 is a 16-bit CPU, while the PIC24 is an 8-bit CPU. The Ickes et al. device includes a 16-bit FFT accelerator and only runs at 4MHz, but it was only fabricated as a prototype; you can't buy it. The Zhai et al. Subliminal device, also only fabricated as a prototype, only runs at 833kHz, and it doesn't even include an integer multiply instruction, but its somewhat limited ALU is 32 bits.

However, _all_ of these numbers are far from the Landauer bound (kT ln 2). Suppose that we don't make any concessions to reversibility in our CPU design, like Metronome and its successors. A 32-bit instruction, then, erases the 32-bit register where its result is stored, costing 32 kT ln 2, or in some situations, an average of 16
kT ln 2. Supposing T = 300 K, 32 kT ln(2) ≈ 0.092 attojoules. That's _over seven orders of magnitude_ better than the prototype Subliminal processor mentioned above, and nine orders of magnitude better than the Cortex-M0-based commercial processors mentioned above.

Wolpert has published https://arxiv.org/pdf/1806.04103.pdf (mentioned in the article, but not linked AFAICT) which gives better expressions for the cost of computation than the Landauer bound. I haven't finished reading it, but it looks really interesting.
Even though this could be the case (that the security team is under a gag order and the marketing/PR team don't know about it), I'm pretty sure a "no comment" response from security would signal the PR team to maybe downplay the whole thing.

Wow, what a blast from the past. My introduction to programming was on an old Apple II with BASIC and LOGO. I was in the 6th grade at the time, and never did anything as complex as looping to draw spirals - I basically used LOGO like an etch-a-sketch.
They mention it's used for 3rd party software, so I can take an educated guess.

It might be, for example, that some 3rd party app doesn't retry database connections. So, you have to start the database server first, and wait until it's accepting connections before you start the 3rd party app.

Just a guess though. You're right...it should have been less vague.
Just the opinion of an internet stranger here, but I think the medicinal benefits are touted because they're a way to get a foot in the door and start the conversation about the utility of these substances. Society still has PTSD (pun intended) from the out-of-control utopianism and concomitant criminalization / smear campaign of the 60s and 70s. Therefore using the substances to help those in desperate need is much more palatable for most people than the less urgent "betterment of well persons." But the latter is (or at least should be) a goal of the psychedelic community, for sure. I for one have been helped hugely, _tremendously_, by psychedelics...and never would have been diagnosed as mentally unwell beforehand.
Maybe, but a lot of airlines start up each year.

It looks like this is aimed primarily at safety considerations, and not at comfort. So I don't see this dramatically making airlines more pleasant to fly on.

What I found most astonishing in the article was the baseline for evacuation:

> Current FAA rules require airlines to evacuate in 90 seconds or less.

Is this even vaguely realistic? Aside from blowing a hole in the side of the plane at every row, this seems completely infeasible.
If you scroll all the way to the bottom of the article you will find the disclaimer

Bloomberg LP has been a Supermicro customer. According to a Bloomberg LP spokesperson, the company has found no evidence to suggest that it has been affected by the hardware issues raised in the article.

Why did Bloomberg not buy a bunch of SuperMicros (new and used) and find the chip? That would be difficult but would turn this into a HUGE story. Even if they didn't have the technology to do so in-house, there are many companies they could hire to do a forensic investigation. The weakness of all bugging is that it has to communicate to the "outside world" at some point to be useful and that communications is discoverable. Even Stuxnet, which was much more narrowly targeted than this, was eventually discovered.
