Ok, I'm going to assume that this article draws from the work of Christakis and Fowler on social networks and happiness, obesity and depression. http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.165...

This is really interesting work (and i would love it if it were true) but there are some concerns about the statistical methods used in these claims. See Lyons - the spread of evidence poor medicine: http://arxiv.org/pdf/1007.2876

To sum up, this idea that you can affect behaviour and outcomes based on your friend group is very controversial.

There are two possible explanations: homophily - you surround yourself with people similar to you, and contagion - your opinions affect your peer group. The biggest problem is that these explanations cannot be distinguished on the basis of the kind of studies (retrospective observational) reported by Christakis and Fowler. To do this, you would need a prospective controlled experiment tracking friendships and outcomes over a number of years.

That being said, I would like to believe it, but the evidence is not strong enough for this to be accepted uncritically.
Strictly speaking, Adobe has: it's called Dreamweaver.
Using TDD everywhere is stupid. I think, tests are most useful between layers of abstraction, especially if you are the provider of abstraction. If you are merely a user of abstraction, it is stupid to unit test that code.

If you have an interface to the outside, then that should be unit tested.
Just curious -- why is PAN a problem? Is it hard to get a PAN for your business?
Right, it doesn't work when you're testing whether foo is a bound name at all. In that case you need to use "window.foo" (or this.foo in Node).

And yeah, it's double equals. The coercion is exactly what allows "== null" to do the right thing in the presence of undefined. Contrary to popular belief, "0 == null", "'' == null", and "[] == null" are all false in JavaScript. "foo == null" doesn't test for falsiness, it just checks whether foo is null or undefined.
What a stupid asshole. How else would you expect an event-driven server to behave when you throw Fib(40) at it? The only legitimate complaint entangled in that strewn-out plesh of vitriol is that Node's http server doesn't have some features that one might like in a web server. Putting a proxy in front of Node is not a problem, because Node's strengths (handling zillions of connections with little memory overhead on top of application state, without having to write your own event system) are not abated.
While it's probably not exactly what you're looking for, Safari's Snippet Editor is great for whipping up some quick HTML with auto preview. Accessible via the menu, Develop > Show Snippet Editor.

No syntax highlighting which is kind of a bummer.

You can still get the large 5pin din connecting keyboards on ebay. Search for "G83-6414" for example.

But I think the 5pin to ps/2 connector may just be a straight wire through to the smaller connector, so you can reverse that?

Threw out turbo-xt motherboards well over a decade ago.

Still have a couple 16mhz 386sx motherboards somewhere that I cannot seem to make myself throw out because they worked fine, just (very, very) outdated. They are so tiny (1/3 board size) that they don't take any space to keep around.

Also have some isa vga cards somewhere - could send you one if you really needed. But the original XT also had an optional color card with composite out that could still be easily used today.

I love to see this level of investigation. It's a great shame that there's not really any programme of funding or support to encourage hacking like this. Hopefully people will dig around in cupboards / attics / basements to find more hardware.
GNU is Not Unix
Saw this film in singapore recently. I don't think it'll tell you anything you don't already know. If it had come out like even 10 years ago, then you might've called it prescient or atleast credit it with identifying a trend. Not today though. Waste neither bandwidth nor money on it. (just my opinion)
Pure utter malarky. My urban high school in Miami was 40% white/non-hispanic, 40% hispanic, and 20% black (minus a smidgeon for the few percent Asian). It was also one of the best high schools in the county - public or private - and many of my friends' parents could not afford private school tuition. Mine sure couldn't.
Original suburbs are generally now just called "the city". They are built on the city grid and generally have relatively high densities. The prototypical "street car suburbs" that surround the urban core of most cities where the first true suburbs.

Most of what we're building today are really "exurbs".
It's going to be distributed -- from the article:

"... will be packaged for full distribution in the coming months in quantities depending on how people like it..."

I assume they'll update this: http://www.dogfish.com/brews-spirits/fish-finder.htm to include where you can find it once it's shipped, but if not you can at least know who to contact in your area if you want to check availability / try to reserve some.
I am not aware of any work of JITs on JITs. But I agree there is a lot of potential there.

One thing I would like to see done is to take PyPy or LuaJIT, and get their tracing JITs to generate JS, either directly or more likely indirectly by emitting LLVM which Emscripten then compiles to JS. In theory that could let PyPy and LuaJIT run on the web with speed similar to what they have natively.

If anyone familiar with PyPy or LuaJIT wants to work on this with me (I wrote Emscripten), let me know! :)
The sad recipe of the 1900's:

- have nice walkable cities for everyone

- start building and selling cars

- cars begin to take space in the city, cause local pollution, and also kill people walking or biking

- don't blame the cars but blame the dangers of city, and thus proceed to build suburbs which are perceived safe, and move there

- build miles and miles of wide and car-friendly culs-de-sac because everybody knows if cars stay on their runway and people stay inside their yards or homes, they can't hit each other

- automobile accidents soar because everybody needs to drive around

- thus, build and sell more cars because suburbanites require a couple in each house, continue blaming cities and leave it to poor people who can't buy a house and maintain a couple of vehicles

- build malls and office parks to avoid going to the downtown at all, but only if you can afford to drive there because there's no other way there

- suburbia is becomes dead during the daytime and conversely office parks die off after the workday, and malls get their share of visits before people go to sleep and this is all glued together by huge traffic congestion during commute hours

- to battle congestion, build more roads and make them even wider: there's more congestion that spreads even wider

- oil prices soar and living gets really expensive in the suburbs: continue to build new suburbs while leaving older suburbs to become McGhettos

There are even different track widths, with the russian system being wider than the most common standard.
Yep, but just FYI, the common counter-argument on HN is that the survival of the species doesn't matter to the individual, so they still don't think it's worth spending money on.
Thanks for your suggestion! I'll see if I can find a good method to implement it.
You referenced that article to claim that Linus does what you did. But that article is quite clear that Linus does not do what you do: He either reverts, commits or stashes first. Had you done that you would not have had your problem.

Its one thing to fuck up and get panned on HN. Its another to go looking for justification that you are right. Its yet another to select a single quote from an article to justify your position when the entirety of the article refutes your claim.

You did a great public service by calling attention to this problem (the problem being not using git properly - nobody is going to hold that against you). Don't ruin it now by getting all defensive.
Aren't roads similarly a net-loss and are 100% subsidized by taxes?

Sure, public transportation is great for young single people. Try going to the grocery store with young kids on the bus. It's virtually impossible.

I see it literally every day:) It hardly seems impossible.

What you need is not less cul-de-sacs, it is more pedestrian ways meshing your neighbourhood and small parks to connect people together. Do not focus on the roads, focus on the people.
This is already awesome, great work. However, if you integrated this with Simplenote, or a similar service, it would be even better.

Jason Calacanis follows me on twitter, I presume it's through here. I find this absolutely hilarious because I basically only ever use twitter to claim special offers and send shoutouts to pirate radio stations.

I presume he's using some sort of automated marketing tool to follow lots of people who will then follow him back, the sly dog.

Thinking about it it probably means that those social media influence ranking tools give me quite a lot of points. I love how ePenis is now a real, measurable value.
> The problem with the space program is that it's gotten about as far as it can go without propulsion and energy-generation systems an order of magnitude or two more efficient.

Exactly! And, materials science. There's this huge problem of radiation in space that hasn't been solved yet without the use of a lot of thick, heavy ("costly") materials. From the little bit that I follow the field, this seems to be an even more challenging problem than propulsion.

My money for the next great advancement in science is on biotechnology. All the signs are there -- the computing power has recently become available to crack some very difficult problems, imaging systems are better than ever, and we are rapidly developing new understandings of biology, including human biology. Scientists can print organs now! If I can survive long enough to become an old man, I think there's a good chance -- if I have enough money, sadly -- that I'll live to be a very very old man.
I'm just wondering why Creole wiki syntax failed on this particular point: for me, the syntax is much more consistent and easier to parse.

And doing a pull, which is meant to safely pull in unrelated changes, to test some things before committing, especially when it was a very simple change on head, is completely reasonable.

I don't think its reasonable. 100% of posters here don't think its reasonable. You just demonstrated why its not reasonable. Yet you say its reasonable.

Here's my rule for version control: if an operation can go wrong, it will go wrong.

Pair programming. I'm half-joking, but sometimes it is used like that.
No point using separate IDs for different services. Google will still tie them together. Here's a little story (that might scare you).

A few months ago, my brother bought an android phone. He synced contacts with his gmail account. And when I looked at my info on his contact list, I saw that gmail had associated my name with a couple of accounts I had made as a kid and haven't used in half a decade. How they did that, I don't know.

In any case, that aside, I really don't mind that they are profiling me as long as the intent remains good. I like it that the ads are tailored for me. I like that youtube suggests videos that I might be interested in. I like it that I don't have to sign in over and over again to login to different services. These are all features to me and a majority of the internet using public.

If you don't want to be profiled you should consider pooling money and creating your own email service with like-minded people, use diaspora/anonymous boards for networking etc. Avoiding google is do-able. It just requires more resources.

I find that most people who are complaining are neither willing to give up a bit of privacy nor are they willing to pay more or work harder to protect their privacy. You can't eat your cake and have it too!

Yes, that's pretty much it. It's not as bad as perhaps it sounds. The age of the solar system means that the asteroid belt is mostly stable, which means the distribution can be inferred.

The Kuiper belt and Oort cloud may throw some outliers in occasionally, though. We don't know enough about them yet.

Thanks! That's a great link.

I will take that idea regarding a landing page heart. Especially considering it's something I can manage to put together myself. Perhaps even throw a "comments" field for suggestions on what features customers would want? I could even respond to said customers personally in regards to their comments/suggestions. Let me know if you think going that far would be beneficial or bothersome to potential customers (I personally would like that type of attention as a customer).

Anyway, sounds good about not outsourcing. I won't bother with that, especially since my website cannot be implemented properly without a significant amount of time and effort... and therefore, money. I feel as if just a landing page with email and suggestion form would be 100 times more useful than some minimally featured, half-assed version of a website I paid for. Since that website might actually end up turning people away.

Any advice in regards to startup events? For instance, there is one in NYC on October 11. I will go, but I won't know anyone. Now, I'm decently outgoing, so I'll try to introduce myself, but should I try to contact people before attending? Then at least I'll have someone to meet and it won't be as difficult. I don't know.

I understand it's a long road. But it's exciting.

Thanks for the luck. I'll be trying my hardest to ensure success. We'll see what happens.

I think it's not only a issue for big companies. I do believe that all entrepreneurs should think about it for their initial step and growth. We live in a post nationalism era.
The issue is how. It's the old 80/20 rule, although perhaps in this case it is more like the 93/07 rule.

We've got the "easy" ones, but we infer there are others we haven't detected. How do we detect them? Space is really really big.

In my eyes, the only viable replacement for del.icio.us is Pinboard http://www.pinboard.in/. I was an active user of del.icio.us and I moved everything to pinboard http://www.pinboard.in/u:adulau (especially when del.icio.us killed the simple (and surprisingly useful) network feature).

Pinboard understood from the early beginning that regular users of bookmarking tend to prefer text-based and useful feature compared to "stack" of meaningless data. By the way, I don't get why the new delicious introduced stack of info when you can use a tag for it...

Maybe pinboard is for the power users who like tagging and the objective of the new delicious is to attract people doing "stacks" of meaningless images.
"Too many founders let emotions and egos cloud a decision that is really a number crunch. Once you accept that there will always be richer and wiser people out there, you'll find that they didn't get that way by taking dumb bets."

Maybe I'll always live in a crummy apartment and have Ramen for Thanksgiving but I completely disagree with this. How I choose to spend the next 3 years of my life is hardly just a number crunch. How I spend time doesn't just have a numeric value attached to it. I respect the author's analysis and to each his own. But, for me it's much more about learning, growing and building than a straight math problem. If at the end I don't die with the most toys I'm really OK with that.
There is a "software crisis". There is no "hardware crisis" and, in fact, has the opposite of "Moore's Law". Both are difficult, right? But we have conquered the latter and we have made few inroads into the latter.

Large systems are almost impossible to create and maintain. Imagine that we could build dog houses and, if we're careful, houses, but nothing bigger that wasn't under constant threat of falling apart? Imagine news headlines of "Chartres Cathedral collapsed again today." And then imagine a response of, "Well, that's because it's hard to build."

What Dr. Kay said, and I'm sure he only backed off of it because it's tiring making these arguments over and over again to people who look on with open mouths, is that there is the equivalent of the arch waiting for us. You, Dave, may not believe it. You may say anyone who complains about houses falling in on themselves just doesn't know it's hard work. I'm saying it's hard work to make them out of toothpicks and dental floss.

The reason I get annoyed in my comments (and had to apologize) is that I've spent 15 years working on a solution and have had nothing but resistance from those who can't see past the state of the art.

You have no sympathy for people who aren't constantly improving themselves. I have no sympathy for an industry that isn't.

IMHO, good testing is hard. I think that something that's probably as hard as writing programs in the first place shouldn't be commoditized into a methodology. I don't particularly dislike TDD, but I certainly don't like it either.

Completely agree.

The best phase to write tests is when you've locked down a part of your program.

Completely disagree.
I realize the situation may have been different when the Applications chapter was written, but I would be careful of the subtle jQuery.tmpl "endorsement" in the "JavaScript templates" section.

jQuery.tmpl is unmaintained, slow, and very broken. It may be worth changing the example.
That's ridiculous. There's a screenshot at the top of the page; it's clearly on Mac OS X, and it isn't as if it claims to be a universal app for the whole planet. Personally I think if the page began with a giant "ONLY ON MAC OS X" disclaimer that would look more like he only cared about that.

It was just an oversight in the Hacker News post title which has now been corrected.
