They disapprove of a Monarchy in principle, but given the monarch doesn't actualy have any influence in politics they don't believe it's worth starting a civil war over it. I think that's fair enough.

edit: This is a classic example of the pragmatism TE is famous for. Sometimes they have to hold their noses when advocating a policy or choosing a politician to back, but that's because sometimes the ideal policy is simply unrealistic to implement, or the alternative politicians are even worse. Occasionaly they get it wrong, and you can fairly disagree with some of their choices, but they always give a clear and honest appraisal of their reasons.

Thanks for that post - helium scarcity is a load of FUD IMO, since if it becomes scarce and thus more expensive, companies will jump into the market and start producing it. Similar to the production of hydrogen for the car market. Rare earth materials are a much bigger issue, since those are much harder to chemically manufacture and aren't a by-product of anything (except recycling)

Not completely in this case.

But, take Lockheed, for instance. They are notorious for running supply chains that stretch across as many states/districts as possible so that whenever there are any possible budget cuts, their lobbyists call up several congressmen and talk about how many jobs in their district will be lost if a particular program gets cut.

There are no evil people in this system. Lockheed is doing everything it can to insure that it gets the maximum possible amount of federal funding. Each congressman is doing whatever they can to keep well paying jobs in their district. People vote for congressmen who can bring high status projects into their district.

The problem is that the interplay between the narrow interests of each individual player results in a system that's constantly stuck in shitty local minima.

Creating a dangling const pointer is pretty trivial. Hell, make it a const reference.

#include <iostream>

struct Foo {
const int &dangling;

Foo(const int &dangling): dangling(dangling) { }
};

Foo foo() {
int dangling = 0;
Foo foo(dangling);
return foo;
}

int main() {
std::cout << foo().dangling << std::endl;
return 0;
}

Neither g++ nor clang warn on this, either. I am not sure why you think const pointers are safe. They aren't. Flat out.

In the sense that you, reader, can write ffmpeg, that's not really true.

Of course you can write ffmpeg. What's so special about ffmpeg? Research how it works, then write it yourself.

Maybe it seems pointless to do that since ffmpeg is already written, but it's not. You'll learn an amazing amount from the experience.

Imagine then the following (stretchy) scenario: an isolated village on an island.

Now the villagers start digging the hole in the ground. Mind you, digging holes is tough business: they have to eat and someone must pay for the food. If all of them work on the hole, who makes the food? But they are smart and the project manager arranges for some of them to cook the food while the rest of the village digs.

After a week the hole is done and after another few days the hole is filled back.

Now they sit at the campfire and think by themselves what great two weeks those were: they were employed.
Even the rare earths (which, ironically, are relatively plentiful in the earth's crust [1], enjoy the same market-response behavior.

1. Can Oprah, or any famous person, support/campaign for a candidate? How is her cashing on her celebrity any different than a person funding an advertisement? And the current laws to a large extent support the idea money=speech. Lessig's group couldn't even follow the campaign laws that already exist (http://www.campaignfreedom.org/2014/11/20/fec-complaint-mayd...)

2. The problem I've identified is that the federal government has grown too large and does too many things. This is the problem, powerful people will be powerful and have an influence on society - through fame, money, etc.

3. Reducing the scope of the government could easily be accomplished if the commerce clause was read in a different way. If granting new power to the federal government required constitutional amendments then it would be better -- prohibition required an amendment, why don't modern drug laws? Additionally, returning the selection of senators to the state government instead of a popular vote would also be be an improvement.

I'd actually recommend the Economist - the writing is generally pretty good (in my opinion), but more importantly, as a weekly publication rather than daily, it's less knee-jerk about getting out the story quickly, and more focused on actually understanding the news and the implications of it.

Ask HN: Why use MongoDB over a denormalized structure in a relational DB?
I'm trying to understand why anyone would use MongoDB. MongoDB sells itself as being faster than the competition by virtue of the denormalized data structures it encourages (no joins!).

Does an RDBMS not also provide this functionality? Why not just create a table in PostgreSQL with a single JSON field? This is essentially the same as MongoDB but with myriad additional benefits. You now have a "get out of jail free card" when you realize you actually needed relationships and ACID. With a "one field to rule them all" RDBMS structure you can start pulling out fields from your JSON goop into meaningful structured relations when you outgrow the document-oriented nature of MongoDB.

What is the appeal of MongoDB when an RDBMS can do everything better and more reliably?

+1.

Most text editors operate text substitutions (like "<-" turning to "←" automatically), so ASCII doesn't seem inevitable anymore (and I believe it's even truthier with virtual keyboards).

I worked in a company where APL used to be very strong (large french truck manufacturer) and they even had lots of programs written in Scheme for assembly-line optimisations in the late 90s. Most of those have been rewritten (should I say... painfully rewritten, and now buggy) in Java in 2005.

I feel like APL/CLisps/etc. were the right solutions but developers/managers were/are scared when they saw some of the mathematical/proof concepts they had to use, and were afraid of when they learned about them at the university.
Yep, I stopped reading there.
This is absurd.

Saying 100x assumes an expected production. All those people didn't do what was expected of them, they did what they loved.
Yes. Part of the idea seems to mostly be that if you have HVEC support via the OS or licensing, you get BGP support without any additional legal hassles.

The evil in the system in Congress whose members use their power to reward and punish, through tax law, funding, and directing other agencies in the government to take actions not in their own best interest; namely the military though they still seem to want to run the Post Office.

You could say this evil is a behavior politicians at all levels exhibit, the focus on bettering their position than good law or exercise thereof. It isn't just Lockheed playing the system, unions get involved too, as do the political parties. Look at all big government boondoggles, Big Dig, the bid for high speed rail in California, and such.

Not sure I understand your point. These are all state tier achievements. If anything it's where the state is either disorganized, broke, utterly corrupt, or all that make it difficult to achieve those goals in the first place.

Phrased another way: Congress elected to raise the costs on all Americans who drive cars or use electricity in favor of reallocating industrial inputs required to satisfy their desires to a project which doesn't support a space exploration program we don't have.

I lose geek cred every time I say it, but NASA is not a science agency which occasionally funnels objectionably high amounts of money to politically favored firms. NASA is a funding mechanism for politically favored firms which occasionally produces industrial biproducts which bear some loose relation to research. If space exploration wasn't an applause light among geeks because of science fiction, we'd have a strong consensus to defund the entire agency.

I thought you were exaggerating (we have a very large stock here in Uruguay, thought we had them beat handily), but you're not:

"Figures just released from the June 2012 Survey of Agriculture and Horticulture in Wales, show the total number of sheep and lambs in Wales in June was nearly 8.9 million, with lamb numbers rising by nearly 5% to 4.6 million and ewe numbers rising slightly by 1.2 % to 4.2 million."

By comparison we have about 12 million sheep here in Uruguay, Argentina has 10 or 11 million, and New Zealand has about 40 million sheep.

"The country has the highest density of sheep per unit area in the world. For 130 years, sheep farming was the country's most important agricultural industry, but it was overtaken by dairy farming in 1987. Sheep numbers peaked in New Zealand in 1982 to 70 million and then dropped to about 40 million."

Area of Wales: 8,016 sq miles (20,761 km²)
Area of Uruguay: 68,037 sq miles (176,215 km²)
Area of New Zealand: 103,483 sq miles (268,021 km²)
Area of Argentina: 1.074 million sq miles (2.78 million km²)

Uruguay usually looks up to New Zealand as a model to follow (similar population and economy).

I did otherwise when interested in the APL/J/K world: the ASCII use of J scared me and I decided to learn some APL first and then, go through J's ASCIIness (I'm still early in the APL part, though.) I find APLs symbols nice and terse, for some of the basic things it's like learning a good editor's shortcuts (be it emacs or vi[m].) You no longer think about how to do X, but what you want to achieve and your hands do it. Of course, I guess with J it's exactly the same once you know enough of it, I just took the other route.
That would take another few articles.
This is such a neat idea, but I wonder if it suffers from vibration problems. Because the blades are mounted on pivots, whenever you've commanding differential pitch, the high angle-of-attack blade will incur more drag and so lag slightly more than the low angle-of-attack blade. Thus the blades won't be exactly opposite each other anymore, creating vibration. Perhaps the blades are spinning so fast this is not a big deal? Probably would be if you scaled up though.
This is a really interesting perspective on cognition, and it all kind of makes sense if you consider the brain to be a black box pattern recognition machine with various built-in biases.

New data is always added to the model, but not in an entirely rational fashion. The updated model is likely to slightly overfit new data ("compiled at the time they happen"), and particularly salient bits and pieces of old data (see https://en.wikipedia.org/wiki/List_of_cognitive_biases) are disproportionately weighted.

There's GNU APL as a free APL implementation. As for learning APL... It's essentially learning what all its symbols do (there are some references for free online from the vendors of paid APLs, just avoid reading about their extensions,) even Wikipedia's page about APL works as a fast reference. I just use it to play around with numbers (yes, I also wrote a Mandelbrot set with it, a one liner that fits in a tweet,) and I'm trying to enhance a little its usability with a iPython-like in-browser "REPL" specially suited for my uses.

N-grams are also regularly used in bioinformatics. For example you can split a
genome sequence into words of length k, where we use the term 'k-mers'. You can
use a k-mer frequency table as a heuristic where ever performing a full sequence
analysis is too computationally expensive. For example if two genomes A <-> B
have a smaller euclidean distance in their respective kmer tables than A <-> C
you might assume that A and B are more closely related in evolutionary
distance. This is just one example and kmers are widely used through out the
bioinformatics field. For instance, the wikipedia entry for velvet has a
description on how they can be used for genome assembly:

"This exceeds the record solar photovoltaic module efficiency of 36.7% reported in July by Fraunhofer Institute for Solar Energy Systems ISE of Freiburg, Germany, using four-junction solar cells of concentrated photovoltaic (CPV) solar system maker Soitec of Bernin, France. The 40% efficiency is the latest achievement by UNSW solar researchers spanning four decades, including the first photovoltaic system with over 20% efficiency in 1989."

"The new results are based on the use of focused sunlight, and are particularly relevant to photovoltaic power towers being developed in Australia" (note the comment from adwn here about that!)
