What he probably meant is: You don't want your mobile to be notified about presence unless you open the client and look at your roster. Or if you set a trigger to be notified if someones presence reaches a certain state. When you control the server side both is possible with XMPP. You could use privacy lists XEP-0016 for that. You'd just have to make sure that the server sends the last presence when you enable presence notification after you disabled it while the client was not in the foreground.
ALMS does not allow broadcast telemetry. They can only pick up data once it's pulled into the pit.
We had a system exactly like this in Norway. It was run by the Norwegian postal service. It was shut down after just a year or two of operation due to lack of use, although it's evident that the main cause was mismanagement. Very few people were actually aware that the system existed.
In most countries milk production is heavily subsidised or price controlled as it produces measurable health benefits to children.

In New Zealand this is not the case - farmers don't get direct subsidies, though they do have a novel tax system around stock management. Even with this they can produce milk significantly cheaper than we pay, but Fonterra's essentially a monopoly and isn't strongly regulated, so we end up paying a lot more than other countries.
It's a seamless experience. Apple doesn't typically innovate on the actual technical software implementation. iMessage at a basic level is very simple. It's the integration in the platform. It's the fact that I do not need to know someone's email address to talk to them on gtalk. Also, what if you don't have a gmail address? Many people do not.

I type a phone number in, begin sending a message, and that seamless/transparent handshake occurs in the background where the device I am about to message tells me it's an iOS device supporting iMessage. I don't need to change the way I use my device.
A note on null pointers
The video is part of an ongoing story: the wide-ranging political and diplomatic implications of decentralized leaks that can't be kept from the public once they're out. This story is certainly evidence of an entirely new, technology-centric phenomenon that I personally find highly interesting.
Isn't it ironic that anyone discusses it on Scott's blog and not on their own blog?
Could you elaborate on this? As massive "Bitcoin deposits" cannot be discovered and Bitcoins cannot be consumed for any useful purpose, most of the causes of rapid price changes to commodities do not apply. What prevents Bitcoin from having a stable price while permitting the U.S. Dollar to have a stable price?
I am not super familiar with this, but I don't think you can use GTalk to send SMS to a regular phone number can you? With iMessage it's the same app as regular SMS on the iPhone, and it uses iMessage instead of SMS if both sides have it, otherwise it falls back to regular SMS, it's a seamless integration that many people aren't even aware of.
Ugh, sign in to view more, no I don't think so.

I will consider your feedback. I agree that libc dependencies should be minimized or even cut off completely but as I told you before the project just began and as such still has to have some minor dependencies. As with anything else free time is all that's needed for things to get implemented.

Thanks.
I think the only practical way to do something like that would be a couple of 12" diameter copper cylinders embedded in the floor connected to either a flywheel bank or a capacitor bank. Then your car would have a very large connector contact at the front and back. (and if it had a plastic pin that went into a groove in the road you would have a life sized slot car :-))

There is actually a lot of research on going in high current, short duration, energy systems. The one I am the most familiar with (which is to say read some of the papers) is EMALS the electro-magnetic aircraft launching system that is part of the 21st century X-carrier effort. That system is looking to replace the steam catapult on todays launchers with what is essentially a rail gun type device. Lots of advantages if you can make it work (like programmed acceleration profiles) but hard to make work. They were using flywheels spun up to 10,000 rpm to store energy as angular momentum and then dumping it into the rails with a genset attached to the flywheel.

nice job! I like how clean the source is, it would be really easy to extend or use as a base for writing ones own interpreter.
How do you find this kind of routine meshes with the sleeping patterns of your social circle? I've always been interested in trying something like this, just to see what it's like.
Surely happiness is relative? I'm sure that many people who we think of as having shitty lives often feel "happy". If you're "consistently happy", then doesn't that just become the norm? To me, happiness is the peaks from the "norm" - if I was consistently happy, then I'd have to re-define what happy meant to me.
The protocol and several implementations (at least in C and in Java) are already there. It's called OTR (Off The Record) http://www.cypherpunks.ca/otr/ Not to confuse with a GTalk feature that has the same name.
The business owner could have been upset because the promotion ended up rewarding an established regular customer instead of converting a new client to a regular. regardless of the reason you were treated unfairly be the account presented.

I have had enough promotions and warrantys turn out to be more work than they are worth (usually some escape clause or fine print) that I tend to either let my wife deal with them (I know... let the flaming begin) or just avoid them all together.
It really depends on where you are. There is a lot of gang activity in the more impoverished areas - even though NZ is a welfare state the benefits are set at a starvation level, which leads to the associated crime.

It would pay to ask locals what they think of an area before moving there. In general it's fairly safe though, the big gangs are more interested in selling pot than getting locked up. The youth gangs are full of angry teenagers as usual, but they're not a big issue. You can walk down the nightlife areas at 3am and not get mugged unless you go down a dark alley.

You could use a superconducting wire. (Yes, I know what you're about to say).
If you're already bringing a nuclear reactor into space, you could use it to heat up the hydrogen and use it as propellant directly, for more efficient travel. (In situations where you need bursts of high thrust and are willing to sacrifice efficiency, you can also go with a hybrid system that uses both nuclear heat and combustion.)

Oh, and fun safety fact: a nuclear reactor isn't actually particularly radioactive until it's turned on. If you launch it out of Earth's orbit before turning it on, you're sitting pretty.
The visa waiver allows for business purposes but it gets complicated. Many go for three months, return for a while and then go back or sort out their full visa. The YC program is only 3 months long so it's not a huge problem for many.

You do have to be in California for most of your time, just because you wouldn't get much of the value otherwise.
Funny joke
This funny joke is just great. It is amazing and I really enjoyed reading it, so I chose to share it with you.
I have thought about this same thing and I think the source code of gnu.org should be available. In my mind websites are non-free as long as they do not give the back end code.
Yep, this is still very much a work in progress. Metacircular eval and macros are up next.
No. (That was easy.)

I'll happily take that back if someone can point to mainstream peer-reviewed publications by at least two independent research groups claiming success with the same approach (or even just closely related approaches). But this article just claims there have been "recent LENR demonstrations at reputable institutions such as MIT, the University of Missouri, and the University of Bologna", without any details and without comment on how those supposed demonstrations were received.

What in this article merits any attention at all?
Again, I'm not saying Dustin Curtis is the only one allowed to use Helvetica and a fixed sidebar. But this blog has copied fonts, spacing, kudos, and generally the layout is exact. Not similar, exact. There's a line that needs to be drawn, and I feel this crosses it.
I have a theory. I think that self-help books and articles actually make people miserable. I'm quite happy, and I manage to be happy without having a list of the 6 essential things I must do every day to stay happy.

In my personal life, the people most into self-help books and the like are the least happy. Correlation doesn't prove causation, so I can't blame the books and blogs -- but they certainly don't seem to be helpful either.

edit: I meant this as a light-hearted observation, not as a put-down to anyone who finds self-help helpful. :) I do think however that it's possible to become less happy by trying to over-optimize every moment of your life.
While I never use the button, the underlying functionality is incredibly useful for special-purpose search shortcuts to things like reference documentation where the top result for a specific key word or phrase is very likely to be the one you're looking for. The example I use dozens of times a day is "universal context-sensitive help": for instance, I have Alfred.app set up with a shortcut mapping "msl SOMETHING" to the the "I'm feeling lucky" result for "site:msdn.microsoft.com SOMETHING", so, e.g., "msl CreateFile" will, with very high probability, take me to the reference page for the Win32 CreateFile function, and — here's the important bit — I can set up similar shortcuts for any documentation site in about a minute.
That's a good point, for instance, Google's car has both on-board sensors and annotated route information. I wasn't suggesting that offline simulations be replayed, but simply that the problem space is to some extent a more perfect knowledge environment than the open road will ever be. Cheers.
Only if you're using cables. No one would do that. You'd have a solid docking station with fixed, solid contacts, as I (and the person with the post immediately above yours) said.

You can use solid, fixed contacts at any temperature that won't melt the copper (assuming that they're well away from anything flammable).
It was from the Leigh book which accidentally leaked the password. Purportedly, it was said in a meeting with people who were largely friendly towards him at the time.

Further, additional dumps were made unredacted after the fact, and some wikileaker's claimed that it was at Assange's sole bidding. [1] Furthermore, they also intimated that it was unlikely the original leak was anything but intentional, given the password which was used, hints that were given, and the fact that they had never done that sort of thing before. Remember 100,000 cables had accidentally released by the Guardian in Feb. '11, but another 250k were released unredacted in Sept. '11.

I'm not sure to trust anyone, but I'm not putting Assange on a pedestal in this case, and certainly I don't think such a statement would be outside of his character based on the many other interviews and writings of his. Of course, he does deny saying it[2], so take everything with a grain of salt.

[2] http://www.itproportal.com/2011/05/25/assange-denies-informa...

EDIT: Just to make a point, and not be revisionist, my statement is largely incorrect about timing and numbers. My brain was temporarily jumbled digging through the articles. Guardian leaked the password, Der Spiegel added info on the file locations (purported to be planted by wikileaks in the linked article), and then wikileaks dumped it all in the open.
I think most of us use idiom in programming to mean 'a form of expression natural to a language, person, or group of people: he had a feeling for phrase and idiom.'

The key is 'natural to a language'. Some writers assume they're helping teach a programming language by teaching what the community regards as the most 'natural' solution to a given problem in order to avoid bad habits. In this sense, 'idiomatic' meaning 'using, containing, or denoting expressions that are natural to a native speaker' is an extremely useful phrase because it implies that a native speaker is an experienced programmer who understands both how to use the language effectively and how the wider community uses it.

'Mores' implies the use of a custom by a social group that may or may not be useful. However, in this case, 'each' is an idiomatic use of the Ruby language. The fact it's awkward to teach what makes 'each' work doesn't detract from the fact that it's widely regarded as a better way to iterate over enumerable collections. To me, the fact it draws on such a large portion of the language may indicate that those parts are actually incredibly useful, and in combination can result in succinct and expressive forms that become easy to work with after a certain amount of education.

The distinction between what's difficult to teach and what becomes natural after a certain amount of education is extremely interesting. I suspect accomplished Ruby programmers originally took a leap of faith and just adopted 'each' because they were told to, then later on fully appreciated the underlying implementation. That doesn't make it less idiomatic, it just makes it more difficult to teach.
"Correlation doesn't prove causation"

Exactly.

In the case of these unhappy people you know, perhaps the very fact that they're unhappy leads them to seek knowledge and solace in these self-help books and articles.
To me, 'being happy' is a vague, categorical, unfocused term like 'good', 'positive', 'introvert', or 'extrovert'. You can go into specific behaviors and feelings and then it makes a lot more sense.

For example, the author could be 'happy' in most areas of his life, but the choices he made in his life could make his dating life harder (if he's single) and he finds he's less 'happy' in that area.
While I might not necessarily follow these (I'm a firm believer that its your personal duty to find what works for you, and someone else's advice won't help) but it was very refreshing to read this, especially how you laid it all out.
In Firefox I can create a bookmark to https://www.google.com/search?btnI=lucky&q=java+6+%s with the keyword set to jd then by typing (say) "jd Collections" in the address bar I get directed to the first Google result for "java 6 collections"

I gather you can emulate a similar behavior in Chrome using its 'edit search engines' function.
The next article mentions aerodynamics - shear force drag, pressure drag - as well as something called vactrains which may get us going really fast.

Happiness is some state of brain chemistry that humans find desirable and, having experienced it once, attempt to achieve that state again.

Contrast this to pain, which most people attempt to avoid experiencing again.
I think its solid advice on a bunch of things you can do to feel energetic and alert every day. I'm not sure I would have used the word "happy" but the advice is good. I follow similar routines and I found myself feeling fantastic.

Occasionally I'll pig out with food, stop going to the gym etc and I notice a huge difference in my energy levels and my motivation towards work and life in general.
You'd have to be pretty dumb to bring copper back the surface. It would be far more valuable in orbit around Earth.

Also NASA isn't, ah, the best example of a cost conscious and frugal organization. They probably don't make a good baseline for the expense of these trips.

Planetary Resources still may never come close to turning a profit, but it's possible you're dismissing them a little too quickly.
Who fact checks these articles?

A quote: "Back in 1989 two of the greatest electrochemists in the world, Stanley Pons and Martin Fleischmann, made a remarkable announcement". Pons and Fleischmann never had that reputation before the cold fusion brouhaha, and certainly not afterward, to some extent because of how they mishandled the issue (failing to publish their methods in detail and other problems).

" ... no reputable scientists were willing to risk their reputations by pursuing a science that many considered equal to alchemy." This isn't true -- many qualified people performed experiments sufficient to show that there was no there there. Cold Fusion is a dormant field for an excellent reason, and the tendentious tone of the article -- that it's all a conspiracy against a legitimate field -- contradicts the facts.

"However, following recent LENR [low energy nuclear reactions] demonstrations at reputable institutions such as MIT, the University of Missouri, and the University of Bologna, ..." Demonstrations? No. Heat generation? Yes. Measured neutron flux (an essential component of evidence for cold fusion)? Zero.

How did this article get out of the tinfoil-hat press and into the mainstream press (assuming CNBC has that reputation)?
For me it's more about perspective and locus of control. Everyone always says that success is a mix of effort and luck. I agree, and I think I've already gotten more than my fair share of luck. So I can't complain about bad luck, bad economy, etc. If I succeed or fail, it's 100% because of my decisions and actions.
I think the only thing I would add to this very sensible list is to have multiple, different classes of tasks that engage different skills. This way you can often work very long but not feel tired or bored.
> You could also benefit from separate `let' construct, because simulating them with lambdas is a bit painful.

> without macros, you can hardly say it's a Lisp, it's a language with Lispy syntax.

These two things go together: many lisps have let as a macro that uses lambda internally.

> I was positively surprised you went for lexical scoping

Indeed; that makes for a much more usable language.
Well, it seems that no one likes a monopoly. It would be a pretty compelling mission for anyone who attempts it. :-)

"There are only two types of people in this world..."

This is always a great indication that the author engages in reductionist simpletonia. There are many types of people in this world, all of which can be plotted along a spectrum between two poles.
I'm in the US but I recently bought tickets via Ticketmaster to a show in Canada. I was going to order parking too, but they wanted to charge $30 to ship the parking passes. One sheet of paper to ship 200 miles, cost $30? And no option to print it out. Feels like it should be illegal.
As per Betteridge's Law of Headlines[1], "No" is indeed the correct tl;dr for this article.

Even beyond correlation not proving causation, it doesn't sound surprising to me that unhappy people are looking for ways to become happy, but happy people aren't. You might equally conclude that restaurants make people hungry.
David Goodstein (physics professor at Caltech) wrote this fascinating article in 1994: http://www.its.caltech.edu/~dg/fusion_art.html. I'm not sure the status of cold fusion research hasn't changed much since then.

The major problem of "cold fusion" seems not to be that it the findings aren't reproducible (at this point, they have been reported by several labs), but that they aren't consistently reproducible even with the same apparatus. Without knowing which factors determine whether or not excess heat or neutrons are observed in a cold fusion cell, it's impossible to know whether the observed positive results represent mistakes, methodological errors, or bonafide (albeit intermittent) nuclear fusion.
I'm fairly sure the visa waiver program allows business, otherwise people in other countries would have to apply for a new visa every time they came here for a business trip.
for is defined in terms of each, so you can still use for on a 'custom object'
Also, assuming a lot of electricity, some form of ion engines would likely be (much) more efficient than heating.

Also, nuclear reactors aren't the ideal way to make electricity in space. Proper nuclear reactors work as heaters for a heat engine, and heat sinks are proportionally much more expensive in space than on earth.

However, solar power is much more efficient. You get 100% efficiency all the time, and it's 30% better in space (near Earth) than it is down here at best. Also, since no structure has to carry any significant weight, you can build things like a flexible paper-thin sheet of solar cells printed on plastic that is spun about it's axis to keep it deployed and spread out.

It's quite a bizarre situation really, a lot of websites are built on or leverage open source software and even give shout outs to what they leverage, but really what we do is more closed source / black box than any desktop software ever was.

Reddit's the only actual open source website I know of (aside from forum/blog/etc kind of stuff).
I wonder about this. I'd like to see more posts about love and how to deal with it in the face of software engineering/startup stuff.

Actually, nevermind.
Didn't mean to be.

I've observed with clients while systemizing their businesses: In the long run in those who don't keep it a priority to document, improve and transfer their knowledge capital regularly, peak out, stall and fade.

By failing to bake into the bread of their culture that understanding and sharing the why to do things a certain way.. maintaining their competitive advantage, they inevitably are exposed to becoming less effective, productive, efficient, ultimately welcoming a culture of accepting less and less.

It's also probably worth noting that I'm not talking about creating a mistake manual, but rather a why manual that helps teach the mindset that creates the types of mindset required to make decisions to grow the business

Businesses that become institutions do so with cultivating a a 50 to 100 year mindset, but few have a 10 year mindset to take what we do today and make sure it's happening while we find the next way to grow.
iMessage fails on the security front. I have received more than one message (via wifi) after I removed the SIM card from an iPhone. This would not have happened with SMS.
i think this is just shu-ha-ri - http://alistair.cockburn.us/Shu+Ha+Ri - in short there are three stages to learning something:

* first, it makes little sense and you follow by rote

* second, you understand and explore

* third you have absorbed and use what is appropriate, naturally

and this is "ri-testing". it's going to confuse shu and annoy ha, hence the defensiveness...

(more generally, i think this is a very useful way of looking at progress. one danger, though, is that it's tempting to think you are ri when you're actually just a ha that's screwing up.) (and apologies for using what i suspect are very carefully defined terms in some marshal art out of context and in grammatically odd ways.)
Microsoft invented XmlHttpRequest during the time that they had the dominant browser.

Ability to make HTTP requests from JavaScript can hardly be described as innovation -- all the other languages had this far earlier. The innovation, though, was using XHR to create highly dynamic web applications without refreshing page, and it wasn't Microsoft that started doing it at large scale.
