Falaí mermão! I taught English in Brazil for a few years, what I'm talking about is the fact that, for students in outside courses (like Ibeu, Cultura Inglesa, Fisk, Brasas, Wizard, etc.) course levels are defined in a generally consistent manner (basic, intermediate, advanced) -- and many of the courses are nationwide franchises.

And I'm specifically not publishing country-specific data because the per-country numbers are not that big yet, and it says much more about who happened to stumble upon this site, as opposed to actual national differences.

Abraços!
the theoretical market for chromebooks is people who only want a computer for facebook and email and want to buy something simple and cheap.

in practice, i think the market is just nerds who want to play with a chromebook because it's new and cool. i appreciate what google is trying to do with chromeOS, and i think it's a good idea, but they have failed miserably at marketing it to non-techies.
Wow, that seems a little pricey for what is offered. I would think they would be able to use an "off the shelf" netbook that already costs ~300 dollars, without Windows, and sell it for ~200. Windows accounts for a nice chunk of the price of a netbook, does it not? I know they don't pay store prices for Windows, but I'm sure they are still paying a decent amount. Does anyone have an insight in to how much Windows adds to the price of netbook hardware?

Facebook Wall Script 3.0 with PHP and Jquery
I clicked on one, and it was discouragingly bad. It pivots on the phrase "as the picture shows…" — which is a hallmark of crackpot claims, from Bigfoot to canals on Mars. The fact that two galaxies appear to be connected by "light" in a photograph is no more evidence that they are actually connected than a photo where the sun blows out a tree's leaves is proof that the sun is a small orb floating a few feet above the earth.

It's one thing to carry out experiments that might one day be used on a battlefield. Such pie in the sky thinking is pretty constant.

It's completely another to adapt a working prototype into a viable device, and as far as I know nothing to date has come as close as that video I just witnessed.

In addition, secure two-way data feeds in real time is pretty much a solved problem, and is currently being used on pretty much every UAV in existence today.

The car has certainly done far far far more good than bad. That's why we put up with the downside (a few deaths a day).

The issue is that there's a small minority of bad drivers who cause accidents. Removing everyones freedom to drive because of those few isn't very fair, and would result in a boring 'locked down' society.

I realize you use the word "somewhat", but I still stand by sipior. Autos are, for many, a necessary mode of transportation that have the unfortunate potential to be abused or misused. Knives can be used to prepare food or kill/maim others, as well. I hope no one thinks we should build robots to do all of our cooking for us on the chance we might slice a finger.
Really? That's too bad. The analogies used to be a significant factor in the tests, and I thought they were an important measure of a test taker's ability to reason. A few years ago I read that most U.S. high schools don't teach proofs any more in math. It seems like we're dumbing down the critical thinking requirements for "kids these days".
speaking about more realistic scenario. We already have air bags inside the car. Honda started to make external airbags targeted at car-to-human cases. There is no technical problem to implement external airbags for car-to-car cases. Start with mandatory front-side external airbags on heavy cars like full-size SUVs and work the way down and sideways.
Goodness this is horrible.

That man, Jerry Guy, admitted he had been drinking and taking prescribed painkillers the night of the accident, and had been convicted in two earlier hit-and-runs. He served six months in jail for the crime.

Additionally, as someone noted in the linked story, the bus stop was nearly a mile away from the crosswalk.

They ask people to use public transportation, but make it as inconvenient as possible to do so.
>They only have to do better than the current, abysmal ~3,000 fatalities per day.

It's not 3000 fatalities per day, it's more like 150.

Furthermore, this needs to be balanced against the potential for some seriously ugly 1984-style stuff when you give an external authority control of millions of cars. I don't understand how someone can complain about TSA regulations one day and turn around and ask for mandatory automated cars the next.
I'm getting a lot of down-votes, which is cool but maybe I haven't explained my reasons for thinking like this:

I love email mostly because it is not controlled by a single provider; I can always run my own email servers (and I do). I also love email because you can be anonymous - you can use a pseudonym - heck, you can fake the headers to make it look like you're bill-gates@microsoft.com, although smart email clients will figure it out. I also love email because it doesn't have a single point of failure -- if one email provider goes down, that won't block the Internet. I also love email because if you have your own domain, no email provider can freeze you from sending or receiving emails, although they can try to do that.

Google+ does fix some of the annoyances of Facebook, but it fixes none of the more hard-pressing problems and still has many problems that Facebook has.

Google+ / Facebook are nothing like email.
Yeah, the jury seems to still be out on this one. If you are using SQL then plural sounds better. But if you are using some sort of ORM or data access layer, singular frequently works better (ie "rows = db(db.item.id>0).select()").

#10 also seems to be routinely violated, again, especially when ORM is used.

Could you comment more expansively on why you find this situation unethical? If so, can refrain from leaning on the legality of the situation. I haven't heard a good explanation that didn't use the legal ramifications as a central support.
>Is it even legally okay to publicly make an example of someone like that?

Yes, it's entirely up to the prosecuting attorney to prosecute with vigor. Again, if you up-jump the charges you often lower the odds of conviction because the burden of proof is raised, but so is the penalty. This also gives the prosecuting attorney grounds for a settlement (plea to lesser, civil charges, but with stiffer terms).

So it could all be posturing that a judge will throw out... what is good to know is that Schwartz can likely attract the best defense attorneys to fight this.
At least from this example it doesn't seem broken.

Very very sad to lose someone to such a stupid accident.

As far as computer controlled cars, my instinct is to disagree with you, but living in Houston, and considering that 10%-20% of Americans are taking prescription drugs including hypnotics/sedatives (Ambien etc.), and anti-psychotics/anti-depressants (Prozac, Wellbutrin, Cymbalta etc.), it's easy to agree that perhaps, many many people just should not be driving.

Or in some cases, leaving the house at all.

Besides, we have computer controlled cars, just not widely available.

How the New York 'Times' Came Back From the Brink
Agreed. There was a nice post on HN recently (http://news.ycombinator.com/item?id=2714149) about combining fabric + vagrant to manage django deploys. The vagrant part handles the "use puppet or chef" part of provisioning, while the fabric includes the "run quick commands on the VM" part after the VM is already provisioned. I learned a lot from that!
I would say: come up with a better idea. I know it's in vogue to claim that "ideas are worthless' and "it's already been done before", but quite honestly, I think that's crap.

Personally (me, one individual) have 4-5+ solid "ideas" with significant market research behind them. None of them have competitors, whatsoever, and all of them solve huge problems in the marketplace. The only thing holding me back is a lack of technical skill, which I am solving by learning how to program.

So, that being said, I would think a little harder. Rome wasn't built in a day, and an original idea isn't likely to come in a weekend.

Notably, the locator [1] for post offices (or collection boxes, etc.) is still unchanged.

My main use-case for this part of the site is to answer the question “where can I deposit mail and still have it collected today, without driving all the way to the main office?". The top-level results page only shows business hours, which do not exist for the collection boxes on the side of the road, and may even differ from collection times at the official locations. This is in addition to the lack of any Sort function to use this information.

In general, there could be more information presented, and better organized, to really take advantage of the space.

How detailed the requirements should be?
If you ask developers how detailed the requirements should be, they will tell you that they want to know exactly what clients want to get. And this is good! Vague, high level, general requirements are not going to work for them. However clients have slightly different approach to this matter ...

Alternative Solution, with iptables and perl below.

You send the magic string to any tcp port and it'll instantly kill all SSH logins and disable the root shell. Send the string again and the process is reversed. Caveat: if your syslog contains trigger entries more than a year old this will blow up.

I also recommend you disable root logins and password authentication, but if you insist on enabling them, this may work for you. Modify as necessary.

Fair enough. I'm just trying to advocate for more music and fewer strings attached. I know that some exists, but, as you point out, things are still far from simple.
When I took this test I scored slightly under the median for my age group. Determined to improve, I looked around for a vocabulary-words app for Android. I didn't see anything quite as simple as I was looking for, so I threw this together:

The cheapest MacBook Air is indeed $999:

http://store.apple.com/us/browse/home/shop_mac/family/macboo...

Perhaps you saw an older model that's on clearance.
To be fair as far as I can tell, there is no directly comparable Windows Acer Aspire One. All the 11.6" Acers I see run on a different chipset, and they're all only $20 cheaper than the Acer Chromebook.

When I first tried out the Chromebook, I thought the same thing about price. But I'm pretty sure Microsoft licenses Windows for these netbooks VERY cheaply, so there's not much price to be shaved by swapping out the OS.

To hit a significant price difference Chromebooks would have to skimp on the hardware compared to their Windows/Linux counterparts. The Chromebook I have already struggles with flash, so without dropping support for that completely I don't think there's much to trim off the CPU end of things. There's a little room to skimp on the HD compared to Windows, but not a ton. So basically I don't see any route other than being ad supported, rentals or some other type of Google subsidy for Chromebooks to actually become cheaper than the low end of the netbook segment.
The Macbook Air starts at $999 according to http://www.apple.com/macbookair/. Looking at the cheapest Chromebook vs. cheapest Macbook Air it is $650. I'm not considering educational pricing here.

Slicing a finger and losing an entire family in a horrible car crash are hardly comparable. Your comparison is absurd.

If 80 people died every day (source: http://www-fars.nhtsa.dot.gov/Main/index.aspx ) in the US from chopping up their vegetables, sometimes entire families slaughtered by a wayward broccoli stem, building robots to do our vegetable-chopping for us should definitely be a high priority.

Bear in mind I'm not advocating the removal of cars - merely that great efforts should be made to introduce self-driving cars over the next generation or two.

People found ways to not be bored in the millions of years before the invention of the automobile. The thrill of riding a horse. The thrill of running when you're fit.

Personally, I find driving to be the definition of boring. The distant, halcyon past is the brief decades (out of the entirety of human history) where we were able to live under the illusion that we could build a road system that would handle the burgeoning amount of traffic without gridlock.
I've been using a Samsung Series 5 for a couple weeks (I have the 3G model which is priced at $499).

After having tried this out, there's no way I would call it worth $499. Maybe I'm just spoiled from my MacBook Air but the Series 5 is heavy and has a cheap/plasticky feel to it. The trackpad has responsiveness problems and in general just feels funny to use. All in all it gives off kind of a "toy computer" impression which is unfortunate.

Ask HN: Are there any examples of big node.js installs?
I am investigating using node.js for some large upcoming projects. It is obviously vertically scalable. And I know you can use multi-node for single machine muti-core utilization and of course we have our load balancers for the front end. At a proof of concept level, it has proven itself. However, I need a case study or two to show the upper management that it is in fact all-around capable of being a rock solid production environment that can service millions of users. Does anyone know of any such proof that is publicly available?
The number of deaths is around 90 a day in the US. That's down from like 115 a day 10 years ago. Still more to be done, but I don't think it's as high as some think.

this guy really opened my eyes. I think he knows very well what says.Shortly and to the point
I see this new notion of interviewing people before working on an idea is becoming quite popular. I know it's useful to know if people would find something useful, but I think there's the danger of never trying out really innovative ideas. Much like writing, building things is an exploratory process. Typically my own ideas evolve and improve only once I actually start building them. This is especially true for things that are useful to myself and not just other people.

There is the risk that you will waste your time. But doing something new and useful often involves risks. And seemingly silly or bad ideas are often the best - http://paulbuchheit.blogspot.com/2007/06/three-types-of-idea...
I don't know about the latest revisions, but the CR-48 had a terminal that was basically only useful for SSH. So if you have a dev box setup somewhere that you can SSH to, it makes an okay dev environment (for someone who uses emacs or vi).
Perhaps not, but if the DoJ's perspective is that mirroring JSTOR without permission ultimately constitutes wire fraud, then the series of tactics he took, legal or not, establish mens rea: they constitute evidence that Swartz' actions were knowing and purposeful.

I like the article you cited, but it seems predicated on a lot of assumptions about the evidence the DoJ has. Like I've said elsewhere: if the only thing Swartz was doing was taking a shortcut to getting bulk documents to analyze, then this is clearly a misstep on the DoJ's part; an extreme overreaction. But if they have evidence that his plan was to dump them onto BitTorrent, they have a case. I hope they lose the case!
