After watching a video on Khan Academy on Lattice Multiplication, I assumed that it was the "new way" of doing multiplication by hand.

I certainly would use lattice multiplication in preference to traditional long multiplication methods if I ever had to multiply large numbers by hand. I wouldn't be able to say which method is better for a 7 year old learning the concepts though.

I'm pretty math-challenged these days without a calculator (gone are the days I could run the numbers in my head faster than you could punch them into your calculator), but I tend to do weird things like break stuff down into primes and then multiply it out from there.
Fukushima Daiichi #1 is a couple weeks shy of 40 years old (from first criticality, 26 March 1971) at this point. There are a number of prototype, and production, reactor designs that are in principle "meltdown"-proof. That a reactor that old didn't survive one of the most massive earthquakes ever recorded is no basis for abandoning nuclear power.

Unfortunately, that's all we're going to hear from some corners of the nuclear debate, regardless of the facts.
Sorry, they did no wrong. They live in the USA and they have the right to manage their trading/strategies/prices the way they like.

I don't think I agree. Let's think about the situation (assuming the posted article is correct): the price of wheat was relatively stable, on the order of $3-$6 per bushel. This system was fine, and stable, for years and years.

Then some financial analysts come into the picture and decide that this is an untapped market where they can make some money. So they do their magic, and -- again let's assume the article is correct and this was actually the cause -- wheat prices jump like crazy.

The result, in real terms, is that a larger portion of the world had to be considered "food insecure," and I'd imagine that some people actually went without food that wouldn't have otherwise.

Is a financial firm's ability to make money (legally, even) more important than people's ability to eat? Or even just more important than people's ability to feel safe and secure in knowing where their next meal is coming from?

From my perspective, that's a resounding no. The ethical and moral obligations easily outstrip the financial benefits.

As you say, maybe it had positive aftereffects, that the Tunisian government stepped back and decided it needed to take local action to make the country self-sufficient. And that's great, but I don't know that that would work everywhere in the world.
I can't downvote your comment, nor did I want to. I'm only posting this here because the English language media has been slow with their coverage and this is an exceptional situation.
This is kind of like saying, "I really believe that commercial airlines are the safest way to travel, but if they can't keep them from crashing sometimes I won't ever fly again."

I know, its not an exact paraphrasing but the intent it still there. For one thing, the Japanese are not the super awesome technology supergiants that the common wisdom from the 1980's in the US makes them out to be. Europe, Japan, South Korea, and the U.S. are all technologically equivalent. Its more of a matter of how much certain tech is spread out. When it comes to stuff like nuclear plants, we're all basically the same.

Gotta give 'em a break. Japan, as far as I know, has not had many accidents. We've had a number of them including Three Mile. When something the size of a continental plate snaps with enough power to shift the speed of the planet and a country's position on the globe by over 10 feet, there's not a lot of blame that can be put if it happens near a nuclear reactor.
I wasn't suggesting otherwise, merely that I am oblivious to what the current price of a gallon of gas is and have been for some time. Since giving up my car, I have been in a gas station twice. I pay zero conscious attention to such things and rarely have the opportunity to just happen to notice it. So, in this longer view, I attribute the general rise in gas prices mostly to peak oil -- which in no way negates the fact that in the shorter run there are many factors which influence the price of any given commodity.

Furthermore, I imagine that even if I did get everything locally grown/made, the price of gas would still have an impact -- unless the farmers were all Amish or something and didn't use gasoline-powered farm equipment.
This is actually a proof that nuclear energy is not green, not safe, and should not be used any more. Nuclear plants can't resist direct airliner impact or big earthquakes or anything that the engineer didn't think about.

System calls are expensive for a variety of reasons (including, but not limited to, the cost of extra data copies and the cost of switching security "rings"). For system-call heavy applications (in particular, networked services), moving things into the kernel provide huge speed benefits. [0] [1]

You are right that it's generally a stupid choice to make, but you're dead wrong in assuming that it's got no benefit at all.

The official line from the press conference being given by the Secretary General of Japan is "We don't know and we are investigating further, however radiation is still within acceptable levels." This means the only real update from this press conference is that the evacuation perimeter for Fukushima 2 (the second power plant) has been increased to 10km (from 3km).

To the contrary, however, somebody was quoted that the explosion was the containment building for reactor vessel 1. If that is the case it would pretty much be the worst case scenario for both Japan and the future of nuclear power.

German politicians voted runtime extensions for many nuclear plants. Many plants in the world are just old, because regularly rebuilding plants would make real green energies much more interesting. I think such a disaster on the environment justifies stopping using nuclear energy, even if it means more constraints on energy price and availability. If I look at the German nuclear energy discussion, there is a lot of greed involved. That is not something we can afford.
I'm sure they are large; I was thinking mostly that as 20% of Japan's energy and a nuclear reactor are on the line, they'd be able to move many tons of batteries. Also remember, modern cars weight 1.5-2 tons, and are carried in sets of 8-10 cross-country by truck.
I'm not criticizing Japan.

I thought the new designs were classified as ALWRs - advanced light water reactors (light water meaning they use regular water).
I think he's wrong here too. I can remember using nmap back in the really late 90s. Which wipes out a lot of languages that aren't C.

C was and is a good choice. I'd be a lot more surprised if it was written in Java or Perl.
There are degrees of affectedness, though. I live 2 miles from work, bike in during spring/summer/fall, and my employer provides food on weekdays (technically on weekends as well, if I wanted to go into work then). I tank up on gas about once every 6 weeks, it costs me about $30, and I spend maybe $25-30/week on food. It's well within my budget, and would continue to remain so even if gas went to $10/gallon.

That's a far cry from someone who commutes 20 miles to work in an SUV and spends $60/week just on gas. These people are hurting now. If you have the opportunity to re-arrange your lifestyle so that it's a bit less sensitive to oil prices, it may be a good idea to do so.
NISA press conference:
3:36 pm (2.5 hours ago) explosion was reported to them as containment breach, exact situation unknown at present. Further evacuations will be necessary, people should not travel alone. Official says radiation level data 'unavailable at present'. 'We are not sure if the station is devastated or not.'

Not a panic situation yet, according to NISA.

This was a zero-information press conference.

Authorities still investigating, stay calm, 'it depends on the circumstances', etc.

Several reporters asked if a 10km evacuation radius was sufficient, and the reply was '10km is what we decided'.

This looks like an unmitigated disaster in the making.

Haha, but that's not exactly the point. I hesitated about posting the earthquake news much like I'd hesitate posting about, say, the discovery of a new planet. It would likely be of interest to hackers but it's not really in the gamut of Hacker News submissions.

Is it exploding, or are they doing a pressure release?
Let's take the quote:

"Can't we just read the book and know all we need to know?
It turns out the answer to that question is very interesting, because mostly no, you probably can't. At least not in the way you think. There is factual information and then there is mastery of a complex skill. I look at it this way: I can show you a movie of a great piano player, you can meet him and get his autograph, we can even read books on how to play the piano.
Will any of that make you a piano player? No, it will not."

Isn't that comparing learning from a book to watching a movie of a great piano player? This "we can even read books on how to play the piano" is just a minor addition. It should be the main point, but it is not because the other example is more ridiculous and scores more points. He puts forward an obviously stupid example of learning on your own and insists that it explains why learning on your own in general is stupid.

The article is meaningless because skips over two big points:

First, for all those long only positions, for each of them, there needs to be a corresponding short position. The article never explained where all those short positions will come from.

Second, the article said that when the futures contracts expired and there was settlement, the funds would just "roll over" their positions, that is, by selling their long positions in the expiring contracts and buying long positions in the next contract.

The problem is, just why can the funds be sure not to lose money during this roll over process?

Or, if wheat should sell for $5 a bushel and some fund bought wheat at $100 a bushel and doesn't want to take delivery, then the fund needs to sell the wheat they bought (and would take delivery on), and who's going to pay them $100 a bushel for their wheat (position)?

But prices have gone up. I just suspect that there's more to the system than in the article.
That doesn't look like a very controlled pressure release.

If I understood correctly, there has been an explosion in Fukushiman Dai-ichi's nuclear plant. And this is it.

Yeah, whenever there's a quake sizeable enough to feel it, just turn on the TV---they're on it before you even have time to tune it.

There is almost guaranteed significant radiation release.

quote from slashdot:

The outer walls of the Reactor 1 building have partially
blown off, leaving only what looks like a steel frame.

NHK is saying that a sensor within 5km of the plant is detecting
radiation levels approaching 1015 microsieverts
- that is apparently a year's worth of radiation exposure
EACH HOUR

People in the danger zones are being told to cover faces
with wet towels, avoid eating vegetables and other fresh foods,
and refrain from drinking tap water.
Kyodo News agency said radioactive caesium had been detected near the site, quoting the Japanese nuclear safety commission. Radioactivity rose 20-fold outside, reports said. (EDIT: this was before the explosion)

The plant "may be experiencing nuclear meltdown", Kyodo and Jiji reported before the explosion, while public broadcaster NHK quoted the safety agency as saying metal tubes that contain uranium fuel may have melted.(AFP)
it looks to me like a still-standing structure completely disappeared. watch the replay a couple times. there's a white building not unlike 2 other to the right, is partially covering a lightning rod. when you see the shockwave, it's no longer there, at all.
I don't know the credentials of this 'Greg' in any field, but he comes across as an inexperienced blowhard, that makes me doubt he could possibly have any expertise in any area.

It's a nontrivial piece of software and this email comes across as "I can build Reddit in a weekend".
Like it or not there are content-oriented (aka "pages") vs behavior-oriented (aka "applications") sites nowadays. That is not a "vague buzzword", that is reality. The web has evolved from a content publishing platform to also include application publishing, deal with it.

Of course its not a clear cut line and there are huge grey areas. But there are extremes of these that can be clearly labeled as one or the other.

A blog is not the same as an in-browser ide (e.g. cloud9).

These are drastically different use cases and requirements.

jQuery is awesome for content-oriented sites, as is progressive enhancement. I use both myself when appropriate.

jQuery has no structure for more complex business logic - where is the MVC or the PAC architecture? Awesome projects like Sammy.js and Backbone.js are making this situation a lot better - but are still not a full solution like Ext.js.

Frameworks like Dojo, Ext.js, qooxdoo etc are awesome for behavior-oriented applications aka "RIAs". Progressive enhancement doesn't make as much sense here because there is no where near as much textual/semantic content to "enhance" in the first place. Needlessly applying a concept based around publishing content when there is no significant content will cripple an applications usability.

It was not a lie that Ext.js, esp 4, is accessible and supports standards such as ARIA. Here is an example of an Ext.js treeview with ARIA support that is usable with a screen-reader: http://dev.sencha.com/deploy/dev/examples/tree/aria-tree.htm...

I do apologize for calling people "haters", questioning their experience and using the word "fool". Admittedly it does not help to have a useful conversation. Nevertheless I stand by my points and if the earlier FUD on Ext.js is to be taken seriously those commenters would provide some pragmatic and truthful points.

Notahacker, i just realised you made an very good observation of Singapore: her being an excellent implementor but not an innovator.

I really do hope that the Singapore government's efforts to revive its education curriculum works out well. Previously (and rampant in the age group of today's 14-22 years old), students take pride in their ability to organise large conferences and overseas trips. All these demonstrate and place glory on the ability to implement projects. However, it forgoes the emphasis on the ability to create.

Creation is probably what Singapore is in desperate need to sustain its crazy economic growth it still experiences till this day.

Thanks for your reply!
The point that he's trying to make all throughout the piece is that, yes, the speculation is partly based on the civil unrest in the Arab world but that the influx in speculatory money is inflating the issue beyond the simple idea of supply/demand.

In essence, the presence of speculators exacerbates the price hikes that normally come of a volatile market. This turns the whole market into one giant feedback loop.

(this is all assuming that I understand correctly, of course)
Merde, HN needs a redesign. I didn't mean to upvote this comment, sorry.

Nuclear energy is like commercial airlines. Its a very safe kind of power, but sometimes there are accidents. Its unavoidable.

More to your point, saying that a 747 hitting a cooling tower is a reason to abandon nuclear power is asinine. I the entire 100+ years of human flight, there have been exactly TWO instances of commercial planes hitting large human structures, and they both happened within a few minutes of each other in New York.

To your other point, OF COURSE ENGINEERS THOUGHT ABOUT EARTHQUAKES. They're freaking NUCLEAR PLANTS. They don't build these things on fucking fault lines and then say "oops". They aren't franchise McDonald's that take 3 weeks to build and then ask if you want fries with your uranium.

Any plant takes years, if not a decade in some cases, of zoning and study before they move a bull dozer onto a site. This earthquake SHIFTED THE ENTIRE PLANET. Its quite within the realm of being ok that a 40+ year old nuclear plant isn't handling being shaken by that kind of force very well.
I find so annoying to hear all those people screaming Google is evil, Facebook is evil, Apple is evil... just bunch of nonsense. These companies are having their ups and downs, learning things on the way, but their primary goal is to help humanity to communicate and grow. Our obligation as users is to give them feedback and they have to adjust themselves to that, which they always do, even if its sometimes against their own financial interest.
"Chief cabinet secretary Yukio Edano has told a press conference that he cannot confirm that the explosion at the nuclear power plant was the reactor, saying details of the incident remained unclear. He said authorities were prepared for the worst emergency but urged people to remain calm and not to listen to rumours. He also asked them to conserve electricity."

This picture just appeared on Wikipedia, of which I am guessing is the building that may or may not be the one that possibly exploded.
