Quite the opposite, it's extremely hot. They got a paper published in Physics of Plasmas saying they'd reached temperatures of 1.8 billion degrees C.

That's hot enough to fuse boron-11 with hydrogen. You end up with three helium nuclei and some x-rays.

There are several attempts underway, though the one I linked above is the cheapest and apparently the furthest along. I wrote up some descriptions with references here: http://www.climatecolab.org/web/guest/plans/-/plans/contestI...
This is really cool! My 5yo loves to draw games on paper. I let him play on the iPad almost as much as he wants, but often he prefers to draw the games, expand on them, and create his own. We make mazes for each other, and he creates levels for me to figure out.

I go down to our local newspaper, and buy newspaper end rolls for $1 each. These are the rolls of paper left over after printing. They are about two feet wide and probably 100 feet long.

Just today, I found a game for the iPad that lets him create his own platformers. He's excited to try it out tomorrow. It's called "My Doodle Game" https://itunes.apple.com/us/app/my-doodle-game!/id572842495?...

PixelPress also looks promising: http://pixelpressgame.com/

If anyone knows of other easy game dev tools for kids, I'd love to hear about them. I think it's good to keep the momentum going when he's having fun with something.
Yep, it gets a bit tough, but that 460-645lbs range seems like a decent stab at it. I don't get the impression that the Model S's motors are all that heavy compared to the rest of this stuff, but I could be wrong. I'd also wager that the Model S needs a full set of mechanical brakes for emergency purposes, since it still needs to be able to stop safely even if all the electronics suddenly quit while going down the highway at 70MPH. And then there's the question of whether you compare against a 416hp motor, or a less powerful gas motor that would be more typical for a car that size....
Kind of beside the point, really - this kind of micro-optimization doesn't actually improve performance to the extent you want, especially when you consider the downsides.

You can improve HTTP throughput far more dramatically with higher-level optimizations, like moving request parsing into the kernel or otherwise doing things that address larger bottlenecks involved in getting HTTP requests from the network card. The Windows version of Node performs a lot better if you have it use Microsoft's kernel mode HTTP interfaces than if you use the crazy micro-optimized HTTP support in Node that is responsible for this bug.

Ultimately, the prologue in a HTTP request - 'HTTP/1.1 GET' or whatever - is a tiny string of bytes and parsing it, even using the most slow language on the planet, really isn't that expensive. Optimizing that tiny bit of work isn't going to produce enormous gains. Mostly just an ill-advised attempt at being clever.

Well then, you can continue to be controlled economically by your employers, because nobody in the market --- nobody --- is putting your own individual interests before those of the company, except for you.

Personally, I wouldn't want an employer going through lots of effort to figure out what's best for me. I think they'd do a crappy job of it.

I'm thrilled that AMPLab and CSAIL are building this.

For the vast majority of analytics problems and projects I've worked on, approximate numbers are just as good as exact results. One of the biggest productivity blockers can be queries and analytics that take hours instead days to run, instead of seconds to minutes, as these dramatically decrease the number of iterations you can execute and ideas you can test.

We commonly work on sub-sampled versions of datasets to enable interactive queries and analytics - it's really great to see someone formalizing this process and handling the details in a simple and principled manner.
Clearly a case of premature optimization. What is the overhead of testing equality on one char vs the entire string?

How to Rip Blu-ray to ISO on Mac OS X
Although Apple does not give its Mac computer the capacity to play Blu-ray movies, it does not fail people from enjoying high definition Blu-rays on Mac. You can hook up an external Blu-ray drive to your Mac and then watch any Blu-ray movies from a hard Blu-ray disc, or copy the Blu-rays onto your Mac local hard disk drive as ISO image file, so that you can watch it at any given time.

When this becomes necessary, then a Mac Blu-ray copy software also becomes necessary, as it can perform the task of ripping Blu-rays to ISO file on your Mac computer. You may want to check out how DVDFab Blu-ray Copy for Mac will do that, quickly and efficiently.

Another PL theory person checking in...

- The word 'contract' has different meanings depending on which subcommunity you are talking to. For example, the Penn crowd often uses the word 'contract' in relation to refinement typing. The Scheme folks tend to think of the problem in different terms, but I am not convinced there is any substantial or insightful difference between the various definitions. As you seem to be an expert in the subject, I am sure you have read the manifest contracts paper, but I will leave this link here for the others: http://www.cis.upenn.edu/~mgree/papers/popl2010_contracts.pd....

- I have never heard anyone say that types cannot feature blame. I would argue that, for example, Haskell's type checker is quite good at blaming the correct party for a type violation. To argue the opposite you would need a precise definition of blame, and I am aware there are several papers written on this subject. I am sure you could find a definition of blame that excludes static type systems, but I am not sure that definition would be useful.

- Types are not proofs, but typing derivations are. Even if you consider types and contracts to be different, the execution trace serves as a proof of a dynamically checked 'contract' (which is really just a derivation in an operational semantics).
I get the argument that data I store on the Cloud is open to interpretation given the 3rd party (if I give Google the right to look at my data, then it is unreasonable for me to expect privacy on par with a physical drive in my possession), but data stored on my cell (a physical piece of equipment in my possession)?

>I wasted a handful of weeks digging around in debug builds looking at bailout log entries and trying to decipher their IR using the broken log viewer they recommend, and the net result was that my code ended up faster for a few weeks until V8 changed again.

You have the same problem with any other modern JavaScript VM. There is always lots of magic and some heuristics which can easily break. As a result, performance is hard to predict.

For what it's worth, Dart fixed that. Predictable performance was one of its main goals/constrains.

Types themselves are not proofs. In particular, the proposition associated to a type might be a blatant lie - you simply should be unable to find a term for that type. Also, the notion of blame in a contract maps directly to the type checker telling you which term does not type check.
I've traveled all over the world, from South America, India, to China. In all those places, the locals stare and take photos. They stare at me, also a redhead; they stare at my girlfriend, who is from LA and dresses like it. Unlike this sheltered author, when the kids take photos of us, the white ghosts, faragn, or gringos, we don't assume they're going to use it for porn.
We're often the only white couple in the town. Sometimes they've never seen white people. It's what they do.

When my gf was alone in India, she had guys come on to her a few times, but she said it was nothing compared to the aggressive behavior we encountered in Columbia and Cambodia.

People like Rose Chasm, should stay in their small American towns. Someone with such vivid imagination and fragile psyche has no business traveling in 3rd world countries.

I tend to write my own stats code with python, though I've toyed with R for a few papers. The integration via Rpy is excellent.

It's an interesting question. I think the specific circumstances described in the article, where the police looked in the suspect's phone to find his home address is arguably not a bad search. But as they point out in the article, how far can you take it? Can you look up a person's recent contacts? His browser history? His "downloads" folder? His emails?

It seems like a very small step from looking up the last few people he called to going through all his emails...
It is interesting to consider what the implications of this would be. Does this mean the police would be able to open the Facebook app on my iPhone, and browse my profile as well as all my friends'? Including all wall posts, messages, photos, etc? Technically, none of this is stored on the phone itself.

"Heavier vehicles always do better"

You are wrong. At least in the perspective of crash tests.

In a crash test against a wall (equal amount of kinetic energy transferred to the wall and to the vehicle), a lightweight vehicle does better than an otherwise identical but heavier vehicle. This is because its mass is less, therefore there is less kinetic energy to dissipate.

However in road crashes, heavy vehicles fare better because the heavy vehicle transfers more kinetic energy to the more lightweight vehicle.

NHTSA crash ratings are well known to not reflect this difference. But the point remain that heavy vehicles are disadvantaged compared to lightweight vehicle, and the fact the Model S does so well despite its weight is a testament to its good crash resistance.
But all things being equal

Rater irrational requirement, given that we're talking about engineering. It short circuits the entire conversation.

In any case, I find it odd that you find my reference of the Smart "humorous". While the IIHS held their results as demonstrating bigger versus smaller, in actual reality it primarily demonstrated more expensive versus less expensive -- there is no great confusion that less expensive cars often sacrificed safety, and this was true at all vehicle sizes (e.g. some early budget Kia minivans and SUVs were deathtraps). It seems to have mostly passed now that even economical cars like the Cruze are posting stellar results.

But let's assume that a greater weight, by itself, equals better safety. So would that Volvo do better than the Tesla if they filled the trunk full of concrete blocks?

Note that I didn't say that weight doesn't correlate with safety, but that it doesn't correlate nearly as strongly as you seem to imply -- e.g. saying that a large sedan is 1000lbs heavier than another large sedan in no way, I would guess, leads to a conclusion that it will also do better in safety tests.
You seem to have provided no way to get more info, other than posting comments here
Careful about the "warrantless" here. It's true, it's a warrantless search, and don't think I'm saying that's an illegitimate concern. However:

The police already have broad authority to search you and your immediate person incident to an arrest. If this is news to you, you really want to read up on it. This is one of the big things that makes a formal arrest different from mere detention, and one of the reasons the ACLU guides and things like that instruct you to clearly ask if you're "under arrest".

All the DoJ is saying here is that a cellphone is, like your pockets and your bags, a legitimate target of a search incident to arrest. There's apparently a circuit split on the issue. There are other things that aren't legit incident to arrest; for instance, certain kinds of car searches aren't lawful solely because of arrest (trunks can be searched if cars are impounded, but only for "inventory", and can't be searched IIRC if the car isn't impounded; similarly, being arrested outside won't give the police the automatic authority to search your house).
Love it when the goal is to be better than the best, nothing less is tolerated, and the engineering makes it so.
I have to assume that even with the special privileges mentioned in tingletech's Wikipedia find, they are still required to actively use and protect the trademark, or otherwise be vulnerable to dilution. If they don't defend the trademark from everyone (regardless of whether the everyone has good intentions), they lose it. They don't really have much choice in the matter outside of documented legal action.

I prefer that police have less power than more power. That being said, this is how a system of checks and balances should work.

I'm hoping the supreme court says no but if they say yes, I am at least happy that the correct process was used rather than police continue to search phones while waiting for a supreme court decision.
It is interesting! If you get arrested driving your car, the police can't then go to your house and copy all your private papers; they need to get a warrant to do that. But in 2013, you're as likely to be carrying around all your private papers as you are to keep them in your house. So it can't reasonably be the case that an arrest gives the police access to your accounts online!

I (hopefully) learned from mistakes of others. My friend got burned. He was promised a "share of the profits" if company gets sold, he was young, after college, his boss knew how to take advantage of him. Sure enough company gets sold. Most good people had left (except as it turns out the others who also got promised privately large exclusive! windfalls). In the end it was, of course, blame on some technicality. "Sure I would have given you those millions, if it wasn't for the lawyers, those pesky lawyers, wouldn't you just want to drown them, sheesh...", stuff like that. Oh well, he runs his own company now, but it was a valuable lesson.
That only applies to the members (the kids), and not to the scout leaders.
I carry around a Tom Bihn bag. I do not generally let people look inside of it. When stores ask, I leave. However, if I'm arrested, the police will be allowed to search that bag, despite it being a physical pice of equipment in my possession. That's because the police do get to search you, rather thoroughly, if you're arrested.
Isn't the question what rights to privacy do you have after you've been arrested? I assume a cop could look through your wallet and pockets, so I can see why there is an argument they can look through your phone.
Okay. Who should Americans vote for then? Here's what the Conservative party had to say during the 2008 election cycle:

"Although our country has thwarted new terrorist attacks since 2001, those threats do persist. That is why our reform of the Foreign Intelligence Surveillance Act was so vital, and why the Democrats' opposition to it was so wrong."

Hmm, sounds like they were promising more of the same.

If your suggestion is voting for an independent, is there a realistic scenario where an independent candidate could get elected in the United States?
Really? You don't think that might have been relevant to the story? And since you have just said that you weren't doing your Full Disclosure stuff at the time I assume that you went on someone else's podcast and talked about this stuff. That associates the company with what many consider unacceptable behavior because you are their representative. Now I wonder if the conversation wasn't more on the order of, "The CEO thinks we have an appearance problem, so we are going to have to let you go"
I've been looking for examples of applications built with scala and akka that I can learn from. I've built small, toy-ish stuff but I feel I learn a lot by looking at examples. Any have any recommendations?
Maybe that's like the car/house analogy: the stuff on your actual phone is like what's in plain view in the passenger compartment of your car, but the stuff in your Facebook account is like what's back at your house.

But then, that only buys us a couple more years of reasonable delineation; eventually technology will get us to a place where all the data we want to protect is always resident with us.
And what the article and several commenters are saying is that it absolutely is your responsibility. Why? Because you can control your own actions, you can't control management's. Management isn't obligated to pay you anything, and you aren't obligated to work for them. They choose to pay you something and you choose to work for them; you also choose how much to work for them, and your choice might relate to how much they choose to pay you (and if they continue to choose to pay you).

Leaving is absolutely the right choice if the amount they're willing to pay you is wildly out of whack with the effort you're putting in and value you're creating, because it frees your time up to work for somebody else who will value you (and pay you) more. Everybody wins.

I can certainly see that. Do you count "main body text" as 'content' in your designs?

I can imagine myself working with a web design until I was sick of seeing lorem ipsum. This might lead me to under-value 'content' from the perspective of the reader. You think such a phenomenon happens with web designers?

Or could it be that Apple did some kind of brainwave analysis on rats (or users :-) and determined that low-contrast was better for some purpose, then the design community just cargoculted it?

> In 2007, the police arrested a Massachusetts man who appeared to be selling vodka from his car. The cops seized his cellphone and noticed that it was receiving calls from “My House.” They opened the phone to determine the number for “My House.” That led them to the man’s home, where the police found vodka, cash and guns.

You do realize the ironic of your claim that English is currently the most prevalent language is also the status quo, right? If the Earth is to used a single language, why would that be English (besides the status quo, which you obviously dislike)?
So much truth in that post, though I found it a bit histrionic. but I can't stress this enough, (especially for young developers) work hard but keep your eyes open.

Remember to ask yourself, "if this startup/firm/company went to shit tomorrow, what would happen to me?" ... if you think that people at that firm are going to take care of you when things get bad ... slap yourself. Just like in the OP, you might luck out and have someone care enough to give you a soft landing, but that is the exception and not the rule. Always make sure you don't get caught out there,

- passively scan the market every 18 months and go on an interview or two. At worst you'll realize how much you're being taken advantage of, at best you'll realize how lucky you are to have your job.

- Stay in touch with direct contacts at companies that sound interesting who reach out to you, especially on linkedin (I ignore 3rd party developers). If they took the time to reach out to you, just respond with a "Hey I'm not really looking to leave right now but lets stay in touch". Grab coffee with them, and find out what they're up to. This way if everything goes to crap you have a warm lead for gigs, instead of competing with your teammates to get your resume in front of hiring managers in your city

- Keep developing your skills, get on mainstream technologies right after they go mainstream/hit critical, that will make it easier to not chase every shiny new fad. That will increase your marketability and make it easier for you to find opportunities that your peers will not

Above all, don't let being an engineer blind you to company politics. Pay attention to whats happening, read the tea leaves so you can be ahead of bad news ESPECIALLY if you are an immigrant. This has served me well over the years. Once I quit a job because I got a bad feeling that new management cared more about head count than quality ... lo and behold, my replacement was laid off just 6 months after being hired.
