Quick crash course: there's two major kinds of radiation, actual particles (alpha and beta radiation, which are helium nuclei and electrons, respectively) and high-energy electromagnetic waves (gamma radiation: like x-rays on steroids). Radioactive isotopes (such as those coming from Fukushima) tend to emit both, as they decay into non-radioactive elements. So once an atom emits radiation, it's done radiating (unless it's decayed into another radioactive particle, but eventually it'll hit something stable and never radiate ever again).

So the isotopes arrive at some rate, and they decay into non-radioactive elements over time. (That's what the "8-day half-life" in the article means: after 8 days, only half of it will be left.) At some point, the Japanese engineers will get everything cleaned up, no more isotopes will arrive, and all isotopes will eventually decay.

Even if the Japanese take their sweet time getting things cleaned up, the isotopes are still decaying over time, so they won't accumulate unless the Japanese truly screw up and start releasing increasing amounts of isotopes.
Much faster! They should really switch to this.
Ah, many thanks :) It was being thrown around all over, but no explanation.

>Threat – means that there is a level of coordinated human involvement in the attack, rather than a mindless and automated piece of code. The operators have a specific objective and are skilled, motivated, organized and well funded.

Seems odd to specify "mindless and automated piece of code". Does this mean Stuxnet wasn't a "Threat"? I'd say it fit all those requirements - specific goal, wide-ranging tech use, and everyone saw it coming but nobody managed to stop it.
Every time he uses "APT", take a drink.
This is one of the biggest problems: no feedback system for accounts. Since there is almost no barrier to entry, it's really easy for scammers.

Having grown up around guns and hunting, I can tell you this guy's story just sounds worse and worse. Laws and hunting ethics generally precludes use of artificial illumination to hunt by, cf:

http://www.africahunting.com/hunting-africa/1321-namibian-ph...

http://www.michigan.gov/dnr/0,1607,7-153-10366_37141_37704-3...

No "fair chase" here. Somebody quoted Parson's as claiming it was completely dark as he lay in wait for a hungry elephant to walk right into a field of, well, elephant food. If that's the case, he either used artificial illumination to shoot, or there was no very good way for him to tell whether he was shooting a cow with calf, a calf, or even one of the villagers he now so adamantly (after he gets called on it) and frankly unbelievably insists was the true mission of this hunt...a mission that just happened to come complete with film crew and GoDaddy logo for everyone.

Sounds fishy. I don't fish (or hunt) anymore.
Bravo on scoring two jobs, but a little bit boastful all the same. What a show off :P

Show HN: iWagerr | A Twitter app to track and share personal bets
Link: www.iwagerr.com

I made iWagerr after realizing that I had no easy way to track trivial "bets" or challenges that I'd wager with friends on random stuff (say, Manchester United defeating Arsenal, or Butler beating VCU, or Obama winning the re-election etc). I had also come across a post on Quora in which a user mentioned that there was no way to easily keep track of non-financial, trivial bets, so I realized I wasn't the only one with this problem and decided to work on iWagerr over some weekends.

So with iWagerr, you can now easily challenge your friends to a bet over anything, and keep a track of your win-loss record (and earn bragging rights!). :)

Do have a look and let me know your comments on anything (concept, design, problems etc).

I laughed so hard at this:
When asked for a comment on competing with Calacanis’ new incubator, Y-Combinator founder Paul Graham replied: “What’s a Calacanis?”

Definitely the funniest AFD joke i've seen today. Not quite as funny as the comments from people looking for news.calacaniscombinator.com but still great.
Perhaps the same way one might solve a 'real world' (ie physical store) issue. You create the network equivalent of the 'Good Housekeeping Seal of Approval'.

Typically the way that works is that someone diligently looks at every app and provides a rating based clear and transparent metrics. They do this in a largely unsung fashion as early adopters or randomly curious people begin to validate that their ratings correlate strongly with actual quality.

Then, once they reach critical mass, the app vendors will attempt to corrupt them (or at least influence them) by sending them 'free' apps or 'previews' which don't exactly match what they actually ship. Depending on whether or not this new effort has been around the block before they will either lose all credibility once they highly rate and app where the 'review copy' was significantly different than the 'store copy.' Or they have some other fail mechanism (like not actually reviewing the app instead trusting some third party's opinion)

If they dodge that bullet they will begin to grow in influence as more and more people will start using their ratings but that will also increase the demand rate ("Why haven't you rated app Donglefritz yet?") now it will switch from being something they were doing because they and their friends were tired of all the crappy apps and gaming the app store ratings, and it will start feeling like work because they are feeling pressure to get more and more apps rated. Also apps they rate poorly will start complaining, and some of them might try to intimidate them with legal proceedings (justified or not).

Suddenly the value equation will be all pear shaped, they will want to stop but too many people are counting on them. They will want to find some way to 'monetize' all this work since they are getting poor reviews at their day job (or no sleep) because of all the time they are spending rating iPhone/pad apps. They start taking advertisements and have to deal with how an app they rate poorly actually gets lots of downloads because the same app is advertised in their tool or on their site. The ad isn't an endorsement but they need to figure out how to explain that to their customers who previously only had messages coming from them that were not paid for.

Typically it is at this point where they 'sell' their brand, apologize and move on with their new found wealth swearing that 'next time' they won't cave in like that. Their new owners will milk the brand by turning it into a pay for play mouth piece for app vendors which will easily double their investment (since the brands legitimacy will die more slowly than the value of the rankings).

Once the brand is completely discredited and usage has dropped it will quietly fold and disappear never to be heard from again.

Oh, I'm sorry you wanted a solution? :-)
The sad thing is that it would be quite easy to drastically improve Craigslist. First, a simple CSS and design cleanup like this one:
http://www.wired.com/images/article/magazine/1709/ff_craigsl...

No drastic changes, just a cleanup. Then you add an advanced search tool with maps and filtering based on some criterias like distance and price.

Then there's issue of spam. Solve these three issues, and CL is basically "fixed".
The best thing about this site was this link in the comments: http://www.techcofounder.com/

In the developer job market, I think this is OK - because they are in such high demand. If this compared jobs as entry-level marketing associates, I would've felt more dissonance towards what you mention - but in this situation, I think it was OK and not too ego-driven.

It would be for me as well, but there are many people who swear by Visual Studio, and Microsoft is generally very developer-friendly. I'm sure there's reasons beyond corporate dictate that many companies choose to develop in Windows.
Too bad it doesn't work.
Why would an applicant care whether other employers score good developers over sating their own desire for an ego boost?

I don't buy it.
I agree with both of you. It's not impossible to be both in awe of our insignificance, and the capabilities of something so puny in the scheme of things.

It may seem arbitrary, but the platform an organization uses is indicative to me of a whole lot.

Was anyone else a bit annoyed by this statement? It's a good, wholesome, and healthy thing to say "You guys use Windows and I like using Unix", but it's wrong to say "You guys use Windows, and that says something about your organization."

Why do techies have such a tendency to phrase "I don't like x" as "It is wrong to use x".

news stories about Ricky McCormick printed at time of discovery
The majority of this post is RSA tooting its own horn for catching the attackers so quickly (along with other PR shenanigans). It'd be a nice if we could see a more detailed, straight-up technical version without all the pandering.

That said, the "new defense doctrine" against phishing and other impersonation scams should be, dun dun DUN, public key cryptography. It's not that complicated, and it would save so many people so much trouble if they actually used it. HBGary comes to mind, and now RSA; if RSA had even just signed its emails, not encrypted, this attack would not have happened. Kind of funny that a big firm whose whole business is based on this kind of cryptography wouldn't use it extensively itself.
Stuxnet definitely fits the definition (with a bullet).

It's wikipedia with all the associated baggage. I'd guess what they meant to draw a distinction from was the automated bots/worms out there that just rattle the windows of hundreds of thousands of sites with for known vulnerabilities. Then they install something relatively innocuous like an ad for scareware AV similar to the current huge SQLi attack.
Thank you - that's actually more or less what I mean, though I phrased it poorly. I'm not so much depressed at our insignificance as quite in awe to be able to KIND OF understand something so awesome (and so awesomely small). Or at least have a meta-understanding of parts of it. =)
A nit to pick, since elai has already provided some good examples.

> Most "apartment search" sites that look prettier...

None of these gripes are about appearance except inasmuch as appearance reflects functionality. craigslist is ugly, but that's not the problem. craigslist doesn't work well. I don't want it to look different. I want it to work differently.

A competing site could look much prettier than craigslist and still work no better.

I never said using Windows is wrong or implied anything negative about its use; I said that I don't prefer to develop on Windows and that I like the principles behind Unix.
Right or wrong, there is a sense that some people have that any place that mandates Windows usage to developers is the equivalent of "Initech" from the movie Office Space. At least, that's the feeling I get from similar discussions with my undergrad friends.

I can't tell if this is meant as an April Fool's joke.
Again: he is referring to intra-country variation, you are referring to inter-country variation.

From his post: "Denying the link between productivity and earnings is very important for the modern left, as their entire source of outrage is based on the view that the capitalist system "exploits" the poor. More likely, because of the modern welfare state and because of the growing importance of human capital, more resources are transferred from the productive rich to the poor than vice-versa."

If he were making international comparisons, these two sentences would make absolutely no sense. The modern welfare state does not redistributed from richer Americans to poorer Swedish. He is clearly describing only intra-country variation.

I don't know. The author states that CL is a bad site as if it is an accepted fact. He doesn't make a case for it he just starts with it as an axiom. Why does he assume this? Maybe it doesn't have enough flash, or css shadows or what?

CL is a great site that does exactly what people expect of it. You post classified ads in your local market and people get in touch with you. It is a web based classified ad and it works. When I want to buy something used locally and am not in a hurry I look through CL. Right now there is no other site organized to do this that works and is available in every market. Why should there be? CL works fine.

Because it's free it killed off newspaper classifieds but so what. Their bitter and angry competitors have to resort to dirty tricks like trying to get the police and FBI to investigate CL, which shows how desperate and out of ideas the competition is.
It seems like your problem with Facebook is your friends rather than the platform. While I think letting friends add friends to groups is slightly strange behavior, none of my friends have abused this. I think Facebook sees it similar to being tagged in a photo by a friend which can make sense. Photo tagging can be abused too - but only by people you allow.

The BBC has some of the best camerawork I've ever seen. Other European productions aren't bad either (RTL comes to my mind)

Disclaimer: I'm a layman, but that's my opinion as a South American that has watched both North American and European TV (with long stays in Canada and Austria).
Yeah, it seems like a simple reset isn't valuable.. makes more sense to weight the ratings over history.. so that ratings on the new version matter (much) more than ratings on the old versions.. but old ratings still count at a lower weight.. that way in your case you'd still be fine releasing a v2, but for apps that are consistently awful their rating wouldn't be so easy to pull up.

Serious HFT players are either relying solely on news feeds that won't include April Fools stories or are factor in the date for sources that might report them (like CNN). All of the April Fools stories from legitimate news providers have also clearly explained these were jokes and didn't focus a piece primarily on one company.

You're very diplomatic.

Unless a company is specifically geared around a toolset that doesn't exist in OS X or *nix (game developers come to mind), institutional, mandatory Windows use seems like a great signal for "shitty company right here!".
I'm pretty sure large budget animations are already rendered with higher frame rate for proper motion blur. You can't add proper motion blur with post-effects, like in video games.
Everyday Apple approves around 900 NEW iOS and 50 new Mac Apps in the App Store[1]. In such a huge market, it is quite likely that some would try to game it.

The human curation approach falls flat on such a scale. Machine learning and natural language processing can help us in mining the App Store to detect anomalous behavior and improve the search and discovery of apps.

The statistical models of temporal distributions of ratings and rankings are still emerging and such hightlighting provide a useful resource to train the models. So if you see something, say something.

I picked my first career essentially on the basis of interviewers.

My undergrad (at U.Cincinnati) required all engineering students to take a co-operative education job for 6 months a year. You pick your first job after the freshman year. At that stage in the game, I had no idea what I would find most rewarding (I was in an electrical and computer science program, which left a lot of room to choose).

Most companies sent engineers to the campus recruiting center. They tended to ask dry questions about classes and training. The guy from RCA Semiconductor was personable, warm, and knew how to sell his company. He also "got" that frosh aren't really at the stage where grilling them on technical knowledge makes much sense when deciding who to take a chance on, so he steered the conversation more toward life experiences, interests, and working style.

I went with RCA, with no reservations. Happily for me, it turned out that Tom reflected the company culture in the factory that sent him. Was it the "best" decision? I can't say, but I do know that a truly professional interviewer had a profound impact on the path I followed for many years of my professional career.

Hiring qualified people is hard. Just because you're the applicant today doesn't mean you won't be an interviewer tomorrow. It's better for all of us if there's more communication about these things.
Well he did say that they develop in Windows and deploy to Linux, which in my opinion is just weird even if you are working on things like virtual machines and such why are you using windows for that?

I can't see an advantage that favors Windows for linux deployment but I can definitely see an advantage over Windows by using something that behaves more like a linux system (in this case OSX).
Hi!

I had to leave earlier ParisJS, so I haven't seen your presentation, but people have given me some nice feedbacks! I like the way you take care of performance, it's cool!

But... I'm not sure that caching your result is a good idea. Almost by definition, Javascript is changing the DOM, so are the results eventually. A good practice is to cache-it, but manually is good enough, and at least you keep the power on the lists. I mention this because this is the feature you've highlighted with your benchmark.

Here an explanation of my words :

scope.ready(function(my, $) {

$("h2").addClass("mytest");

$("div").appendHtml("<h2>Test</h2>");

$("h2").addClass("mytest2");

});

>>> My new h2 doesn't have any class.

I'm looking forward to see how this will evolve! Keep going!

I think what you mean to say is you didn't intend to say that. Whether or not you actually did say that is another matter entirely. In this case, the majority of your post seems good. But the big bolded sentence that grabs your eye first seems to be implying that there's something wrong with an organization that uses Windows.

I mean, imagine telling someone you don't like their cooking and then saying "The fact that you use margarine instead of butter says a lot." You're not directly saying anything bad about them personally, but most likely they're going to take it as a roundabout way of saying "Real cooks use butter, but you use margarine. Therefore, you're not a real cook."
