All very cute when you have 2 acres of organic potatoes to manage. Throw in 20,000 acres of variable corn seed and 150 microclimates (waterways, wood boundaries, roadsides etc).
Go ahead and write that app (to manage pests manually) but until then its more efficient (profitable at all) to do a single-pass application of chemicals.

Reading that article, it has little or nothing practical to offer the farmer of over a acre or two (lets call them 'gardeners'). 'hand-picking, erecting insect barriers, using traps, vacuuming'. Try any of that over 10,000 acres. Its ludicrous.

Farm application rates for herbicides (any chemicals actually) are regulated by federal law. Also, chemicals cost money so only a fool over-applies.

The problems with chemicals getting into the water etc are because of city-dwellers who are exempt from the law; you can put any amount of chemical on your home lawn you like and flush it down the storm drain. So that's a problem, sure.

Java has had good stream parsing of JSON for a while now too. Last time I had to do it, I was surprised to find GSON, the library we were already using, had support for it. XML stream parsing vs. model parsing was a much bigger change.
From what I've read in the Play documentation, this is intentional. [0] They say:

I have no real opinion on the matter, as someone who doesn't like working with databases very much, I appreciate the comfort a ORM mapper gives me, but so far, all my web apps have been very small and basically trivial, so I don't know how they work with bigger projects.

It's the same sort of situation in Malaysia. There was a stark contrast in terms of educational methods after I moved to Canada. I was used to memorizing a lot of facts so thinking critically and asking questions was a big leap for me. I did well in high school tests because I was used to all the standardized exams back in Malaysia but I had to really pluck up my courage to raise my hands, be more outspoken and develop my own viewpoints.
Since moving to OS X, I've left Visual Studio behind. At first, I had a boot camp partition running windows so I could still develop our C#-based web product. Then eventually we changed the product significantly enough that moving to an OSS tech stack made sense.

I'd probably still be using some MSFT technologies if I could use a VSS-style IDE on OS X without virtualization (I tired MonoDevelop, but it just wan't the same). I didn't have issues with the speed of Visual Studio running on my beefed up MBPro, but the keybinding stuff was just too much to deal with.

Not to mention, having a ton of different runtime/hosting options is a pretty nice bonus for the OSS stack.

Also, for mostly web apps, I think Visual Studio is massive overkill (but I'll still watch their videos on features).

For now, I've settled happily using on cross-platform tools (PyCharm/WebStorm for a feature rich IDE and Sublime Text 2 for code editing, and VIm when tweaking stuff on the server). Should I ever go back to Windows (likely, because I want a Surface Pro 2), my tooling should carry over (though I'll have to go through some keybinding issues again).

Never again will I use products that are locked down to a single OS. Even the tools on my Mac (with the exception of Keynote) run on Windows and vice-versa.

Yeah! There are more understandable examples further down. suggestion @joombar: since the first example is the first thing people see and it doesn't actually reflect the core usecase, perhaps add a note explaining that the example is contrived for simplicity's sake ~or~ make the primary example represent the core usecase more closely. Cool project!

That would be worse for China because the value of CNY would skyrocket stopping their exports. Value of USD would plummet helping US exports.

Besides, China and foreigners are not anywhere near the biggest buyers of US debt. Fed is. Chinese and Japanese had actually five month net selling period earlier this year.

CME, ICE & CBOE (the major US futures exchanges) all enforce fill ratios as well and have for some time.

Fill ratios are not designed to prevent either high frequency or low latency trading, it is there to prevent a particular form of exchange gaming (quote stuffing).

You are not being clear (and you are being condescending) on what you mean by HFT players & what you find objectionable. Is a market maker that trades 40K contracts a day but doesn't quote stuff objectionable? What about a cross exchange latency arbitrage trade that is not spamming exchanges? If so why?

Also, I've traded Eurex. They have very specific interfaces for low latency/high frequency traders. You can order different classes of connectivity from them that are specifically designed for these use cases. They also have predatory algorithms, so I'm not sure what they have solved.

Caltrain seems to operate on the principle "users are the enemy".

I wanted to travel between San Francisco and Santa Cruz, where my family is. Driving, that takes about 2.5 hours depending on traffic. In theory, the mass transit way of doing things is to take Caltrain from SF to San Jose and then a bus over highway 17.

Here are some of the problems I encountered.

- Caltrain leaves once an hour. This is forgivable, but incredibly inconvenient, and the express train (same distance, half the time) leaves much less often. It would matter less than it does, except...

- I once arrived at the station on time, saw people being let through the gate, bought a ticket, and was turned away from the gate by the guard. The people I had just seen were clearly visible on the platform, walking to the train. But hey, why not make me sit in the station for another hour.

- Multiple times I experienced indefinite delays as the train just sat on the track in the middle of nowhere, unmoving. No explanation was given.

- Caltrain arrives at (and leaves from) Diridon roughly once per hour. The highway 17 bus leaves from (and arrives at) Diridon roughly once per hour. They've been anti-synced: the bus leaves about ten minutes before the train arrives, and the train leaves about ten minutes before the bus arrives. The only explanation I can even imagine for this is that whoever set the schedule specifically hated the passengers.

The upshot is that you spend the better part of your day on what would have been a 2-2.5 hour drive. It's not even feasible to make the trip both ways in a single day.

> Apparently the kids are given the formulas in exams now.

I don't see a problem with that. Memorizing formula is as useful as memorizing anything else, it's not very useful and not a measure of knowledge. Knowing how to use the formula, how to manipulate them, are what they are supposed to be being taught.
Here's my simplified way of thinking about it:

The Chinese government wants its citizens to be relatively poor. Why? because then it can use them as cheap labor that is a valuable tool to leverage on the world stage. Plus, poverty stifles political activism.

How does it keep its people poor? Well, by making sure a USD spent in China can buy 4x as much rice/milk/chicken/etc in China as it can in the US. This will mean income of Chinese workers and merchants will also remain low. How does it do this? By keeping the value of the yuan low, by direct manipulation of the currency, which it pays for by a high import tariff. (Which, again, makes Chinese people poorer by making things coming from outside the country very expensive.)

By using this strategy, the Chinese government uses its people as underpriced laborers that give it a huge export surplus and which it can use to influence world events, as well as to generate vast government capital (essentially capital it is withholding from its citizens) it can use to invest in foreign companies/governments.

(Of course now the picture is muddying somewhat because the extreme GDP growth is making many Chinese wealthy anyway, despite all these obstacles.)
Its probably not worth changing it if it is eg in a file already, but if the process to generate it is a slow one it might be.
"In fact, Wal-Mart’s unwillingness to pay most of their workers a livable wage"

> But that's all it is. It's not an investment.

Ridiculous, simply untrue.

Currency manipulation explains the conversion from yuan to dollars, but not from dollars to t-bills.

Why would China convert dollars to t-bills if they didn't see t-bills as a better investment than dollars?
They did this because they're obsessed with avoiding queues and doing everything efficiently, but have a culture where everyone will queue up for 10+ minutes waiting to avoid paying a couple dollars more? Seems silly the way the author explains the motivations.

The one remarkable thing about their cafeteria that stuck with me was the cutlery. All disposable utensils outside of chopsticks were made out of biodegradable corn and they were the best disposable utensils I have ever used. The utensils were full sized and the right stiffness. There were no sharp edges and the texture was slightly rough, much nicer than plastic.

Since leaving GS, the only thoughts I had about their cafeteria was why haven't I encountered as nice disposable utensils as I had there.

As an identity, the capital account between two countries -- payments made for capital: land, buildings, financial assets, etc. must equal the current account payments made for goods and services.

When we buy stuff from China, they get dollars. If you have a surplus of dollars you want to invest them in something, and that something has to be dollar denominated. Treasury bonds are safe, liquid and politically palatable for all sides.

If we stopped buying their stuff, they would stop buying our bonds. If they stopped buying our bonds, they would have to find somewhere else to invest dollars.

(Interesting side note -- this dilemma is what led to the creation of the Eurodollar market -- in the early 1970's the Soviet Union had dollars from oil sales (the international crude oil market is dollar denominated) and they did not want to put the money into US domiciled banks -- so the London banks said we will accept dollar deposits, but are not accountable to the Fed or other US authorities in these accounts (nor can we borrow at the Fed window) and thus was born the eurodollar.)
In the book he comes off as an overly confident showman. Carmack was everything behind ID software (and to Romero's credit he pretty much admits that).

That said Romero's wild-side/recklessness provided the spark that ignited ID software, almost literally if I recall correctly. Basically Carmack had developed a new technology that allowed PC's at the time to handle scrolling. When he showed Romero it at work, Romero basically said "Fuck this company (softdisk), we're starting our own company right now." So starting that weekend they "borrowed" (pretty much stole, but would bring them back each Sunday night) all their workstations and began making a remake of the original Mario game for PC.

So basically, ID software = John Carmack's genius/technology + Romero's recklessness = DOOM.

Highly recommend this book, I don't read as many books as I like but I just couldn't put this one down.
> China slowly increases their currency peg to be closer to the value of the dollar -- The exporters slowly have a higher profit, and thus the people a higher standard of living

Exporters can't export if the price of their goods increase. It's not that easy to unroll their current scheme.

> They could just buy 1T in oil, copper, or other dollar based commodities. There are plenty of options besides treasuries.

How does one transport and store trillions of dollars of commodities (someone has to store them even if they are ETFs)? Besides, these commodities have a lot more risk compared to t-bonds. If the were able to get the same security as t-bonds in something else, you know they'd be buying those as well.

So do you think that the US higher-ed system is inherently flawed also, with competition between high achievers (i.e. Harvard) and schools that anyone can get into? It's true that there are more resources associated with success, but doesn't that also incentivize people to work harder to end up in the higher bracket? I don't see the "Class-C" problem as necessarily a problem, so long as the person in "Class-C" has the opportunity to get back to Class-A by putting in the appropriate work.

My own feeling (having also observed higher ed in Europe and Asia and other places) is that the US system works better for cultivating high achievement, but less well at making sure that lower achievers maintain a certain level of quality. This means that there is more spread over the bell curve and less in the center. Europeans, on the other hand, seem to prefer more clustering in the center of the bell curve.

This is equally true for wealth acquisition, btw, with Europeans generally preferring not to have extremes (i.e. extremely high wage earners or extremely low wage earners).
As long as your truthful that these are problems your company's facing and are actually hiring it should be fine. Please do hire the person who's solution your going with and put them on that project though.

When I was in Argentina in 2003, there were giant internet cafés (up to 250 computers I believe) were the price of the minute of internet was floating depending on how many people were online: you had a max price, a min price and the current price was just the proportion of used computers (so it was not a bidding market). You had a few screens on the wall telling you the current price (I think they billed at the beginning of each minute).
In the middle of the night the price could get quite low.

FWIW, we've already, extensively tried the idea of not having a State with a monopoly on force and instead managing the world through private property rights and contractual relationships without the State imposing limits on such relationships to address power imbalances, etc., it's called feudalism.

If you already know computer graphics it might be worth a skim just to hear this guy talk - otherwise this seems like a pretty good introduction to the topic (at a conceptual level).
It's rather tricky to predict how a Chinese decision to appreciate the rmb would play out in practice. Many export powerhouses have had very strong currencies for long periods. It's not as simple as saying US exports would go up and the Chinese economy would suffer. You have to consider that the Chinese have savings and would find themselves far richer in global commodities. You also have to consider the US economy's heavy dependence on freakishly low interest rates.
