grn··on C/C++ Pointer Declaration Syntax – It makes sense
This is a part of philosophy that declaration should look like use. The way of declaring arrays follows from it too.
grn··on Vim is hard, I just want to click around
I'm using xterm with Solarized and it works pretty well. gvim is indistinguishable from vim in a terminal. I haven't observed any broken apps.
grn··on Show HN: ProTracker Web Edition
This is great! It brings wonderful memories of my Amiga 600. I recommend taking look at other projects at http://stagas.com/.
grn··on The 50 Best Websites of 2011
I do. What I like about it is the ability to use j, k (just like in Vim!) to navigate and that results are displayed on a single page. English searches are good enough to replace Google (at least for me), but I still use Google for other languages.
grn··on The man who screwed an entire country
I think that non-wage labour costs can be an important factor. I think they are quite high across Europe. Could anyone tell the numbers for Italy? (for example: in Poland a net wage of 2700 PLN (~ $1000) is a gross wage of 4500 PLN (~ $1650)).
grn··on Europe Plans To Ban Petrol Cars From Cities By 2050
Your reaction to the risks you've mentioned looks like panic. Maximal possible damage doesn't matter. A meteorite hitting the Earth would definitely cause enormous damage but is very unlikely to happen. What matters is the expected value of the damage. What are the numbers in the case of climate change?

I really don't think that trying to preserve as many species as possible is a rational goal. It causes economical harm for example. What's wrong with extinctions?

I often hear about the costs of climate change. What I don't hear about is:

1. possible benefits; what we should assess is benefits - costs, not costs alone,

2. possible benefits and costs of so called solutions. For example introducing electric cars will increase demand for batteries and electricity. That means increased demand for coal, gas or nuclear power. What will be the effects of these?

I'm just very skeptical about models of so complex systems. My skepticism is increased by the involvement of politics and the hype around the topic.

Libertarianism is about liberty, not about optimising statistics like "the cost of climate change" (whatever that's supposed to mean).

The climate will change. That's completely natural and I can't see a reason to stop it (honestly I think it's impossible). Humans and other animals will just adapt and the evolution will continue.

grn··on Ask HN: Use Vim? What Feature "sold"you?
After some practice with Vim I started to think about editing in terms of Vim's commands. That made me very effective. And it's not only about h j k l. It gives you many small tools that you can combine. The basics are actions and movements. Let me give you a few basic examples.

Some movements are:

- h, j, k, l,

- f <char> - the given character,

- w / b - beginning of the next / previous word,

- 0 / $ - beginning / end of the line.

Some actions:

- d - delete

- dd - delete whole line

- y - yank (copy to the Vim's clipboard)

- p - paste

- c - change

- <n> G - go to the n-th line.

Their combinations could be:

- d f . - delete from the cursor to the first period

- d w - delete the current word

- c w - change the current word

- d 0 - delete to the beginning of the current line

- dd 10 G p - delete the current line (that also puts it in the Vim's clipboard), move to the 10th line and paste the deleted one there.

Of course it gives you much more: searching, replacing, scripting, plug-ins, syntax highlight, auto-completion, browsing etc.

grn··on Science PhDs Have Very Low Jobless Rates
Bayes' theorem states that P(A|B) = P(B|A) * P(A) / P(B), so in this case it says P(PhD|jobless) = P(jobless|PhD) * P(PhD) / P(jobless). It seems that you stated it incorrectly but used the correct version in the computation (the incorrect gives 0.2244).
grn··on Great Math Books as Recommended by Our Readers
My favourites would be:

- anything written by Serre,

- Shafarevich's Basic Algebraic Geometry,

- Silverman's The Artihmetic of Elliptic Curves,

- Milne's notes (available at http://jmilne.org).

grn··on Aerial footage of uncontacted Amazon tribe
I find it extremely disgusting. There's nothing wrong with contacting others. Everyday I'm contacted by lots of people: colleagues, marketers, head hunters etc. They give me choice. Let members of the tribe enjoy the same freedoms. Stop treating them like animals in a ZOO.
grn··on Governments shouldn’t have a monopoly on Internet governance
Government accountability is a myth. Governments run into enormous debt, change pension systems, wage wars ... Where's the responsibility? Loosing elections isn't a serious consequence.
grn··on Governments shouldn’t have a monopoly on Internet governance
I still can't see a problem here. A business with a single customer exists in an almost complete vacuum and doesn't influence the market. What's more it's very risky as its revenues aren't diversified. It's completely dependent on its only customer.
