I flit between the UK and Turkey, and the two are both somewhere close to opposite ends on the social scale.

In the UK, you can walk into a pub and talk to people, providing you're not interrupting a discussion, or forcing yourself on the people in the group. It's easier if you're on your own or with one other person to join an existing group, or talk to an individual, but it's not common. You don't make eye contact on the tube in London, but you can talk to people in general outside of London, and especially up north people are more approachable. Do not touch (beyond a handshake at most), unless you're very familiar and there's a high volume of foreigners in the group.

In Turkey (and these are observations as an Englishman so I might be interpreting this wrong), people are extremely friendly and nosy by comparison. Turks are incredibly physical in social groups and don't really have a concept of personal space. In Istanbul women and men intermingle in some social classes and circumstances but not others. A kiss on each side of the cheek is expected when the opposite sex is involved provided you've met before. Don't be surprised if women put their arms around you, tell them their cold and want you to hug them etc. if you're in a social secular group. In more religious or formal groups, things are more separate - men will still hug each other all the time and put arms round each other but women are never touched (unless they're related or married, and not generally in public). When you go out to the country it really varies from community to community and the local culture. The further east the less intermingling with the sexes, but guys are still generally friendly with each other.

The biggest differences between the UK and Turkey are in going out. Turks... good god, Istanbul Turks... You go out around 8-10pm and don't come in till 5am. Getting drunk is a bit socially inappropriate (in most groups) but the party goes on all night.

In the UK, the party normally goes on till about midnight/2am outside, then occasionally continues back at someone's house, but will start between 5 and 8pm. In the UK, getting drunk is not only socially acceptable but expected. Unsurprisingly as the drinking continues, social rules about touching start to unravel.

TL:DR - It's bloody complicated in England, and changes from group to group in Turkey. Grrrrrrr!!!!
Immigration, taxes, landlord issues (the tpoic was "compelling reasons why, despite being a foreigner, I would be a poor option to steal from"), resumes (+), etc.

The earthquake and tsunami weren't the coupled failures they were talking about. It was the loss of external power and backup generators. This is what they didn't expect, because it is hard to predict the probability of an event big enough to trigger these two things failing at the same time.
This site, and Crockford's book both read to me like "numerous reasons not to use Javascript"

It's like JS is trying to rival C++ for having the most cases where sensible looking syntax will do something completely batshit insane.

I don't care if it's the lingua franca of the net, I hate it. And I code in JS all the time.
Once people realize that an online community is a good place to learn and to teach, they are tempted to use it to learn and to teach things that are outside the original or explicit purpose of the site.

That is what happened 20 or more years ago on comp.arch for example and to a lesser extent on other newsgroups about a narrow technical subject like comp.lang.lisp.

In other words, one of the reasons why off-topic things are discussed on HN is that the human desire to learn and to teach is very strong -- especially among people who have come to know and admire one another.
That's one of the reasons I built http://hackerstream.com (http://news.ycombinator.com/item?id=2301871) - it reminds me to vote on the new queue. Hopefully it helps others engage with that forgotten page as well.
The best life hack advice I ever got was from my first internship. It was at an engineering firm and as I was sneaking out the back stairwell for a cigarette (yes, I was a smoker for a brief period, shame on me) I ran into an engineer and he asked what I was doing, so I made something up and said I was running an errand. I returned his question, "what are you up to?"

Engineer: "I'm carrying a clipboard"
Me looking confused.
Engineer: "if you ever want to look busy, just carry a clipboard...."

Worked every time!

I don't buy your last paragraph. Britain has some seriously large open discussion forums such as Mumsnet and Money Saving Expert. Those are well known by the average person in the street and have some serious political weight.

Also: don't confuse London's relative hostility with the rest of the UK. The north is especially friendly and welcoming. Much more so, than say, New York.
The technical aspects are all about shipping massive quantities of data cheaply and reliably.

A very very good book, I can recommend it. The way the book was written is also very inspirational.
Have you experimented with the fps on Android or iOS? Just wondering if it's playable at all.
That's a terrible trifecta.

* Disable root login

If you have root login enabled by default, you're using the wrong distribution. This is 2011, not 1996.

* Change the SSH port

Why are you doing this? What will you achieve by it? In what way does this reduce your overall risk of compromise, and by whom?

* Install fail2ban or denyhosts

That's the only thing out of your trifecta that should be in there. Aside from that, here's why your trifecta isn't a good move:

You're still using password authentication for SSH. Switch to public key authentication. This, combined with fail2ban or denyhosts means bots are not getting in. Period.

You aren't addressing your attack surface area - look at what information assets are exposed to the wider world and how. Once you know what your information assets are and how they can be accessed (either legitimately or unscrupulously) from the outside world you know what you have to protect and how people can get to it. That way you can focus on real countermeasures.

What about your applications? Have you checked your code to make sure you're validating input correctly? How are you protecting against SQL injection or Cross-Site Scripting? How are you handling state?

I put to you an alternative trifecta:

* Know your assets

* Know your threats

* Use appropriate measures to protect your assets from your threats.
In other words, it's a magnificent example of Black Swan.

I'm pro-nuclear because I care about the environment. Greens are no more monolithic than proponents of nuclear power. Maybe if you stereotyped a little less, you'd find you have more allies than you think.
Old nuclear power plants are profitable as hell for operators. That's why they want to keep running them.
I'm having trouble understanding what you mean by that.

Do you mean that you are opposed to the use of technology if it's safety systems are ever fully put to the test, or are you saying that having the reactor core melt and puddle at the bottom of the room where it will eventually cool off and harden is just too catastrophically dangerous?

Either way, it's absurd. Shit happens. In this case, a big earthquake and tsunami. The fact that a safety system has to be used does not reflect poorly on the safety system. The earthquake has already killed far more people and caused more damage than even Chernobyl, and the tsunami has certainly caused more dangerous chemical contamination than whatever radiation may be released from Fukushima.

"do your time" working for the man in a developed country for 5-10 years, saving as much as you can as you go. Then move to a developing country to freely work on projects for pretty much as long as you like. In terms of lifestyle, there are pros and cons, but so far the pros are far outweighing the cons.

I can't really agree with this article. I moved from the Netherlands to the UK, and I was surprised to notice that any Brit who you've met before at least once will give you a hug the next time they meet you. In the Netherlands hugs are reserved for very close friends and family.

Also, I've had people talk to me on the bus, in the queue in Tesco, etc. Quite unusual to me as well.
His heart is in the right place. I think it's more like "not afraid that I will get shot or robbed while walking to the store means more economic activity". "This contract will be honoured" means more economic activity. Just stuff like that.

I'm a bit conflicted by this.

On the one hand, the hex password in the screenshot while quite long has only 16 possible characters. The Base64 password has only 60 possible characters to choose from (for each position) and must end with an equals sign.

The number of possible characters for each position in the original sentence is quite high (94) but in a sentence the actual likelihood of a wide range of combinations being used is quite low (unless deliberately using obsfucation).

It's a very interesting piece of software and presents a very interesting question, which I guess is this:

For a given sentence, which out of Base64 encoding, Base 32, Hex and the sentence make for the most permutations required to crack? If the answer is Base64, 32 or Hex then your tool is helping. If the answer is the sentence then your tool is impeding. I suspect (but haven't done the maths) that for purely single case alphanumeric passwords it'll be base 64, but for mixed-case alphanumeric with punctuation it'll be the sentence. Anyone care to do the sums to lock this down?

Building a nuclear power plant on the coastline of a subduction zone in a country with a long history of earthquakes and tsunamis does seem like a questionable idea.
What is it that is difficult about decommissioning the plants? The leftover fuel/waste? Or is it that the equipment itself has been contaminated. If it's just the fuel/waste, then why can't it be used in one of those whizz-bang reactors that people keep talking about whenever a discussion about nuclear shows up here (or reddit, slashdot, etc)?
The worst case scenario of driving a car is meeting a drunken or sleepy driver and dying in the resulting crash. This happens thousands of times every year and seems to be an acceptable risk. I don't understand why a technology with large economic damage as the worst case scenario would be less acceptable.
Here is a hack for you: Doors that are hung slightly off center or with self closing hinges close mostly for convenience. Hydraulic or electrical closers like you encountered are more expensive, and only installed when they are required for some reason (security, child safety, fire doors, etc).

You mentioned four sets of double doors, which also indicates the designer knew the requirement for positive closure would be a flow issue and added extra doors. Had there not been a really good reason for having the doors be closed they probably wouldn't have planned for the extra doors.

I know you believe your "hack" was innocent enough, but essentially you vandalized a system someone carefully thought out to save yourself 24 minutes over 4 years.

I don't know the architecture of your high school or the reasoning behind the positive closure doors, but I hope to god they were not part of a firewall (walls and closed doors designed to prevent fire from spreading through a building faster than it can be safely evacuated).

Anecdotal evidence suggests that angels are now investing as much as $50 billion

Naval Ravikant, who runs angel list states that there's been an additional $500M that has been invested in early stage startups last year.[1] Which is essentially a smallish VC fund.

Naval has also stated that 240 companies have received angel funding via Angel list this past year. If every company received $1M, that would still only be $240M invested in early stage startups.

I don't understand where the anecdotal $50B comes from.

Also..

Estimates are that there are now 10,000 angel financings per year, and as much as 70% of these deals are now convertible debt.

Naval Ravikant runs the angel list, and he's saying there are only 240 investments that got money via angel list last year. That's a big discrepancy.

I don't have a comment on whether the structure of convertible notes is good or not. I was just very surprised at the numbers Adeo brought up in the article, because they are several orders of magnitude larger than what I'm reading in other areas.

If he has other data sources, I'd love to read them. My instinct has been that Angel List has been at the epicenter of getting all these startups funded, and so I've been inclined to use Naval's numbers in my thinking.

- Persuasion: Mention an idea in passing then wait a week or two. Mention it again in terms of "you know that idea you had ...". This is a surprisingly effective hack on stubborn managers. If they think they'll get the credit for an idea, then they are much more likely to go along with it.

- Drink a glass of water when you first wake up. It will curb the temptation for high carb breakfast foods and reduce coffee intake.

- If you have annual reviews, write a list of your accomplishments for the past year and send it to your boss about a month before reviews are done.

- 10% rule: Allocate 10% of your work time to pet projects that make you happy. The projects should be for the company, and if you have to put in extra hours to find the time, do it. Don't tell anyone about them until they are completed/successful. Bury the failures. This tactic puts a little control and satisfaction back into your life if you have a job that sucks.

New Startup Now Pulling In Over $100k in Monthly Revenues
I write this not to boast, but for two simple reasons:

1) To inspire other YC-rejects, especially single founders.

2) To recruit hackers to help me bring this company to the next level. By which I mean, of course: total world domination.

I came up with a simple idea for a iPhone app to recommend iPhone apps at the end of the summer, began working on it the fall, and applied to YC shortly thereafter. As a single founder, I expected to be rejected, but thought it couldn't hurt to apply. The rejection email came on November 2nd, and I got the app into the store a week later.

At that point, it was pretty clear the app wasn't ready for prime time, so I worked on it and racked my brain for a viable near-term business model and marketing strategy.

This was sorted out and tested in microcosm by the end of the year. I actually pinged pg on New Years' Eve with my modest but promising stats, requesting late acceptance to YC. Unfortunately he replied that it was just too late, and so I soldiered on. I began marketing internationally, in English speaking countries, rolling the eventual profits from one successful country-targeted campaign to go after the next larger country in my list. Ireland. Success. Australia. Success... Canada.. The U.K...

Finally, on the night of February 15, I went after the U.S. That was a pretty intense night. But all worked as predicted. And one month later, it continues to work.

Over 800,000 downloads to date, 4.5 star rating in the store and a nice constant revenue stream of over $100k per month. Check it out: http://itunes.apple.com/us/app/id399128529?mt=8

That's as a single-founder, with no investors, and only the advice I could squeeze out of my friends.

But this is just the beginning.

Of course there will be: An iPad app. Android. Internationalization. Vast improvement of the recommendation algorithm. An in-house advertising system. Marketing pushes to get the app to at least 10x users by the end of the year.

We're also going to expand this from just apps to books, movies, music, and so on. Cars? Fashion? Let's see what works.

So there's our basic business plan for all the world to see. And we're not afraid. Go ahead, try and steal it. You know it's all about execution and position at this point. And we've got an excellent position and fantastic execution.

But who's this "we"? Right now it's just me---the founder---and the business assistant I just hired. An excellent developer friend will be hopping on board soon.

But really: I want YOU! Quit your Google! Quit your Facebook! Quit your Apple! Let's forget about getting acquired and build something with which to acquire! Come with me, fellow hackers, and let's conquer the world!

Anecdotes of how things happened long ago are less relevant than this incident. With the methodology you're proposing, we'd have to conclude that modern medicine doesn't work because medicine had such a horrible track record in the Middle Ages.

Also, "safe" is relative. Walking down the sidewalk in a good neighborhood is generally considered safe, but it is dangerous relative to sitting in a fortified bunker. If the impact is several orders of magnitude less than we'd expect from, say, coal, then we can say this was very safe indeed.
Using "biggest in recorded history" as an approximation for "biggest possible" seems weak to me. Proper engineering will look at the numbers and account for events outside of the historically observed range, but within the probability distribution. The "biggest event we see in 1,000,000 simulations of the lifetime of the plant" is likely much larger than the "biggest we've seen in history."

Which isn't to say that it was bad engineering. Just that this being the biggest quake in history is not an excuse.
So what was the treatment that enable you to increase your concentration? Not medication I hope. I'm bad at focusing on one thing for more that 30 mins at a time, and just accept it as one of those things in life.
