Wow, I'm seriously considering adapting this for my shell scripts (with code recovery via mercurial, since I'm weak of will...). Actually, I bet there are already others doing the same, because code deletion in personal shell scripts probably turns out to be an unalloyed good.

Consider this: you've got some script that does a sequence of operations using the standard tools. Somewhere you change between imagemagick and graphicsmagick and some image doesn't get made thanks to syntax differences; after this you've used some clever shell filename expansion expression or regex to move/delete files, but the missing image changed your working context enough that suddenly you're in $HOME doing an rm -rf .! The environment is just too fragile and powerful to completely automate everything you might need without setting up enough safety mechanisms, confirmations, and sanity checks to largely nullify the value of scripting as a nearly zero development programming toolchain.

But if shell code were trivially spec'd for pre-/post- conditions and misbehaving code gets noisily deleted (noisily so everything isn't packed away into code versioning purgatory by cascading failures when a tool like rename is accidentally uninstalled)---especially if the shell of pre-and post conditions were left around stub code... Imagine the beauty of your scripts directory!

Replacing some slain block of code is trivial since the tools you need are already mostly written, and you've done something close to what you need before---plus the whole point of shell scripting is that it should be effortless and fast to produce.

If you've built a massive, multi-purpose utility, it deserves to live only as long as it runs flawlessly---after which, you should slice it down or replace it with an inevitably more reliable equivalent that was written for the same purpose years (or decades) ago.

Best of all the conditions that deleted your broken cruft even remind you exactly what you needed to do when you're re-implementing something, but often without pre-studying the entire system to ascertain what world state you are getting and what you need to produce. Brilliant!

This may have started out somewhat tongue-in-cheek (since most programming environments are at least somewhat stable and feature significant error detection and recovery facilities), but I think there's some dead serious application in the quick-and-dirty, often unchecked and fluid environment of traditional shell scripting. The more I think about it, the more I'm amazed my quarter million keystrokes of live scripts woven into my every task on my Linux desktop haven't produced more catastrophes (or any meaningful accidental data loss) or left a trail of silent failures for me to find only long after the causal bugs had manifested.

I cant see this being a good thing for the internet industry. A lot of websites rely on advertising to keep their websites running.

Sure users can already do this, but that has been limited to a very small subset of users, and was always user choice. Automatically doing it for everyone through that isp is crazy.

I wonder how this could relate to censorship, first ads, what next? Just a thought...

If by "not an investment", you mean that he doesn't believe that it will throw off more net-present value cash than a similar investment in the S&P, then I strongly disagree.

He may think that it would not have done that without his investment -- so it could be both, but Buffet promises investors that cash will be deployed more efficiently than you could by just buying an S&P index fund.
What evidence have you got for this? He runs a public company, and demanding stuff is not really what he does, he is out to make money.

Is this a metaphor?

It seems to me it isn't saying that casinos are like software development, but pointing out human psycology using the casino as an example.

The same reward system is there because the psycology (human) is the same.

TLDR; If I compared the performance of the same car on a road to a dirt track, I'm making a comparison, but not a metaphorical one.
Correct. Equation (8) can be used as definition for thermodynamical Temperature whereas equation (7) tells us about the direction of heat flow.

I'm not sure what's best to be honest.
I don't really like the misleading headline, although it seems as though the actual paper does it as well (http://arxiv.org/abs/1211.0545). Temperature is conventionally defined as the average kinetic energy of a collection of particles.

However, in statistical mechanics, you derive thermodynamic relations from the principles of quantum mechanics. It turns out there is a term β which for most purposes seems to match up with 1/kT, where k is the Boltzmann constant and T is classical temperature. According to this article, there are some occasions where "conventional" T and quantum mechanical T do not match up.

The most famous relationship in statistical mechanics is:

S = k ln Ω

S is entropy. Ω is the partition function for the microcanonical ensemble, and it corresponds to the number of quantum states available to a system. (In English: Ω is the number of different configurations that a system of particles can possible have.)

Another relation that can be derived is:

1/kT = ∂ln(Ω)/ ∂E

Substituting the first equation into the second, we get

1/T = ∂S/∂E

So what would a negative temperature imply? That increasing energy leads to decreasing entropy. My guess is that these researchers have created some system that does exactly that.
I think what was meant was that the AMD driver supports almost any ATI/AMD GPU and the Intel driver supports almost any Intel GPU. For Mali you can try the lima driver.
Solar energy investments are financed through tax incentives. Buffet is doing this to reduce his tax bill.
Not too bad, but here are a few observations:

1) It feels too dark. Dark is fine, but there doesn't seem to be enough contrast to even it out.

2) The news grid is too hard to follow. Not sure where a new story begins and ends.

3) You forgot about advertisements in these mockups. Ads can't be an afterthought. Especially for a public company.

Are any laws of thermodynamics violated here[1]? If not, why is this experiment interesting? As a physics student, let me check: 0. Probably not. 1. Not directly applicable 2. Nope. 3. Nope.

Sorry, I should clarify :]

I don't think this isn't an investment, but I think there were motivations beyond purely investment; and having heard him speak and read what he has written, I am taking a guess that he was motivated out of an idea to influence good (while still making a sound investment).
Ok, mind officially blown.

Still wrapping my head around the notion that you can flip the energy signature on atoms at near absolute zero and have that result in mirroring to the other side of the temperature number line.

Also intrigued by the notion that 'dark matter' is just 'regular matter' but flipped into the negative temperature side of the scale. Which really makes one wonder about the nature of heat.
Tanks for pointing out Joda Money, didn?t know that one yet.
"hopefully"

Oh. Not rules then? Well, what rules. How about giving it a rule "children must not die". Apparently we're big on that one. Except, wait, we mean "US children must not die", so we can still bomb foreign suburbs where children are known to exist. But then we'll need "children must not die on US soil" because it is still possible that the union of (isa US minor citizen ?x) and (isa-resident baghdad ?x) is non empty and the AI would be unable to act. Of course then we need, "US children must not die except in a car", because otherwise the AI would have to destroy cars.

Ok, so lets abandon rule based AI altogether and model our AI on biological processes like humans. Well humans would never cause mass suffering of other humans. We have laws against it. Oh.

As others pointed out, there are two definitions of temprature, usually it is related to average energy per particle and formally it is T=dS/dE (S is the entropy, E the total emergy of the system).
What I do not understand, is why is this news? A negative emergy is not very uncommen, for example lasers have negative temperature.
This does not sound like Buffett's style at all, from what I have read in his collective essays:

http://www.amazon.com/The-Essays-Warren-Buffett-Corporate/dp...

He is incredibly passionate about capitalism. Especially smart capitalists responding to pricing signals intelligently. And the symbiosis of good management and good investors to keep companies efficient, take smart risks, and earn consistent, healthy returns.

Making huge, counter-intuitive investments is nothing new for Buffett. (Railroads anyone?) I imagine he is doing this for the reason he usually does: he thinks he is getting a huge amount of value for a low price.
Or clone to start your own based on a current one.
Yes, I think it has potential.

It could also be nice to be able to directly embed the image in forums, so have a direct link to the image (might also be useful for reddit ?).

I know that then, it makes it a bit harder to exatract money, but adding a "created with phrase.it" at the bottom should help with that.
So Facebook for Windows 8?
The SunPower facility has already sold its power under long-term contracts to SoCal Edison: http://www.elp.com/articles/2013/01/antelope-valley-solar-pr...

So from Buffett's perspective this just looks like a bond. I don't think it's a bet for or against solar, but rather a bet on deferred cash vs present cash (so on interest rates).

Gambling is generally waging money on an outcome determined by (a) chance or (b) the actions of others.

Chess, bowling, pool, and darts are games of skill; all events in the games proceed directly from the player's actions. Players can play these games for money themselves but generally cross into gambling if they place wagers on games in which they are not participating.

Boggle, Yahtzee, and Candyland (among other board games) are largely or entirely based on chance (i.e,. the dice rolls). Similarly, the card games enumerated are also games of chance (because skill is not a meaningful determinant until you reach the upper echelons of players).

NY appears to have gone pretty far overboard with their enforcement of the gambling laws, but the actual laws themselves (i.e., the distinction between gambling and non-gambling) is pretty uniform across the states (excepting NJ and NV).

This actually fits Buffet's investment model. He tends to purchase only when a company is down or undervalued and then plays the long angle. He's not a trend investor, he invests based on assets and P/E, etc. AKA "Traditional" value investing methods pioneered by his mentor Benjamin Graham.
>"Normally, most particles have average or near-average energies, with only a few particles zipping around at higher energies. In theory, if the situation is reversed, with more particles having higher, rather than lower, energies, the plot would flip over and the sign of the temperature would change from a positive to a negative absolute temperature."

Unless I'm missing something that is complete nonsense. If more particles have higher rather than lower energies the average shifts up and the most particles have average energy with just a few with much more energy. There is nothing to limit the maximum energy of particles like absolute zero on the high end.

I didn't read the actual research article, but this fragment reads as the usual disfigurement of actual information commited by a journalist attempting to explain a concept he/she doesn't understand at all.
Products fall into multiple categories based on patterns of usage and intended audience.

Some products are daily/heavy use products which should optimize for the expert user. These products need to be designed such that, once the user has an understanding of how to navigate and understand the product's functionality, they can perform regular actions with ease.

Examples: A Todo list, a weather app, or an app for sports scores and the news on a mobile phone. A POS (Point of Sale) system where the operator has some sufficient time for training [Keep in mind that POS systems are designed for fast transactions to keep lines short and moving smoothly].

--

Other products are used many times by different users, infrequently. These interfaces need to be designed such that they're intuitive, require as little handholding as possible, and should offer 80% of the benefit for 20% of the effort. Additionally, that 20% of the effort should be possible by almost all of the people who enter into the experience.

Examples: a photo kiosk at the local drugstore, a fast food ordering counter with an iPad or self-checkout system at a grocery store.

What does this have to do with UI walkthroughs? Because the first class of products are not designed to be intuitive on first usage, they need scaffolds (extreme way of conveying this is a "crutch") for the user to understand their operating protocol. Once the user understands how the system works, then they will be able to use the product quickly and effectively on a repeated basis.

help. what do you people think of the idea.
God this is such interesting stuff. How do we still not have a fully featured open source NFL stats-rosters-game charting API? Who wouldn't want to contribute to that project?

Other than cool data visualization stuff, the obvious implication is the potential to devise a profitable system to pick games against the spread. The guys at Football Outsiders have done a decent job at it and made a proprietary algorithm that picked games at 58% this year ( which is over the threshold you need to be profitable in Vegas ). But even those guys are still having some trouble getting access to and aggregating the data in a usable format.

I really want to sit down and start playing around with some of this data so I appreciate you putting this together for everyone. The NFL needs an open source API and this is definitely a step in the right direction.

True that. It's information architecture fail!
Yeah, I will admit that information does end up being the main problem. I've been doing this long enough that it's pretty much second nature these days, and I just find myself going "but what is there to teach?".

I've taught workshops on other subjects before, and usually once I get going to writing cirriculum that question answers itself in spades, though. Just need the motivation.

I'm finishing up another personal project right now, then I may start on this. I suppose I don't really have much room to complain when I've already set out a solution that just needs to be done. :)

Or better yet the other other way. Assign the public defense a budget in line with the prosecution's budget.

I was a juror on a murder trial and the thing that was most striking was the huge disparity between the prosecution's team size and resources and the defense's complete lack of any meaningful resource whatsoever. It was a very sad week of my life.

Show HN: I think I re-imagined IRC on mobile devices
I have hosted my own IRC server, for a small community of coders and friends, since 1999. I never really strayed from using mirc or irssi, when I'm on a desktop or have a keyboard. On my iphone, the options were pretty lacking, though. The best true IRC client for iphone is one called IRC999, in my opinion. These clients all bugged me though because when the phone would go idle or shut off the wifi, the client disconnects.

Sometime in early December, an idea hit me about an IRC client that would function sort of like Twitter's mobile client. It'd defer the task of maintaining the IRC connection off to a server and it'd expose an HTTP-based API for the mobile app to use.

Anyway, so that's what I've done. I wrote a web server / IRC client that logs chat data to a database. Specifically formatted data is exposed via HTTP so that it can be easily consumed by a mobile client. I used node.js and couchdb for these two components. I also have the basics of a iphone app. The app can be configured to point to any URL / port to use as an API.

These components are all open source because I think that's important. Since the server component is just an IRC client, it could be connected to BNCs like ZNC, and should continue to function just the same. Might need some BNC-specific commands, though.

I just wanted to show this and see if others thought it was a neat idea. The project is still hacky but I'm actively building it.

Aside from the photo gallery, which actually feels improved, I think everything else about this redesign went in totally the wrong direction. A massive sect of users is stuck in the "give me simple, stupid" mindset, and the platform popularity is really to blame. While it's a decent attempt at "beautifying" the interface, I think it's somehow more confusing.

Also, the design seems to be missing a way to shove hundreds of ad impressions into my eyeballs with each click -- a definite thumbs down in the facebook world.
