Liquid Cooling On the Rise As Data Centers Crunch Bigger Data 25

1sockchuck writes The use of liquid cooling will accelerate in the next five years, according to experts in high performance computing, who cite the data-crunching requirements of scientific research, cloud computing, bitcoin and "big data" analytics. "In the HPC world, everything will move to liquid cooling," said Paul Arts, technical director of Eurotech. But there's still plenty of resistance from data center operators wary of bringing liquid near servers, and cost is also an issue. Liquid cooling can offer significant savings over the life of a project, but the up-front installation cost can be higher than those for air-cooled systems. Immersion cooling has gotten a surprise boost from the rise of bitcoin, including a large bitcoin mine inside a Hong Kong high-rise.

You know that you don't have to just add useless and uninteresting words to something that already had substance, right? At least borrow some quotes from Socrates' Dialogues to spice things up: There is admirable truth in that. That is not to be denied. That appears to be true. All this seems to flow necessarily out of our previous admissions. I think that what you say is entirely true. That, replied Cebes, is quite my notion. To that we are quite agreed. By all means. I entirely agree and go along with you in that. I quite understand you. I shall still say that you are the Daedalus who sets arguments in motion; not I, certainly, but you make them move or go round, for they would never have stirred, as far as I am concerned. If you're going to say _nothing_, at least be interesting about it, post anonymously, or risk looking more clueless / foolish. This is why the moderation system is in place, and mods typically don't listen to inanities like "Well said" when deciding on what to spend their points.

1. I'm too busy to sit around thinking up additional words to throw in so I can score "mod" points

2. The people I like on Slashdot are too busy to read a bunch of additional words I only threw in so I can score "mod" points

3. It's not in my nature to waste words, or to waste time

If other posts here on Slashdot are any indication, "Mr. Councilman" is just as likely to lose political points by supporting the poor.

Actually this particular councilman represents an extremely high-rent district--Manhattan's upper east side. I doubt there are many wealthier neighborhoods in the world. He's not doing this to 'score points', he's doing it to do the right thing.

It is my opinion that poverty is partially systemic. Our economic system depends on there being a pool of available workers (unemployed and underemployed). So as long as there is capitalism and a functioning free market, there will always be poor people. That being the case, we have a responsibility to make sure the basic needs of everyone are met. Increasingly in order to succeed in school and in life, Internet access isn't really a luxury.

Well said

shutup. just shut the fuck up. you neither know you are talking about, nor have any valid point to make. its not about solving the digital divide any more than the housing thing is about solving poverty. its been widely and clearly shown that there is an increase in opportunity and outcomes between homes with and home without internet access. you're essentially complaining about improving someones potential opportunities to enrich themselves and make their life better and maybe even get out of that housing you mock. but again, you have no valid point, so therefore theres little sense in talking sense, like pointing out to you that without subsidized housing many of these people would be on street, homeless, increasing both crime rates and homeless and deaths among the impoverished. Theoretically we are a civilized nation. But a civilized nation doesnt advocate intentionally making it harder if not impossible for those most disadvantaged to improve themselves, nor advocate for them to die quickly and get out of the way.

Well spoken, bro

The "digital divide" is a real thing. It's the difference between spoiled people like yourself growing up with a computer in your home, and inner city kids who have no computer access at home and have to wait on line at the public library to get a 15 minute time slot.

If you don't recognize that in this society those without computer access are at a disadvantage, you are as stupid as you are uncaring.

Submission + - Power -- And by that I mean Free Broadband -- To the People

NewYorkCountryLawyer writes: Slashdot member and open source developer Ben Kallos @KallosEsq — who is now a NYC Councilman — is pushing to make it a precondition to Comcast's merging with Time Warner that it agree to provide free broadband to all public housing residents in the City (and by free I mean free as in beer).

Comment As an actual, full-time chess coach... (Score 5, Insightful) 128

I am a full-time chess coach for K-5 kids. I have over 200 students that I see every week. At first I though this article was going to address the very real demand for more skilled coaches in K-5 schools. Instead, the article is trying to push a software/hardware solution that would make it "easier" to adjudicate games and tournaments. This solution is addressing a problem that doesn't actually exist.

Here is the problem they present as an example: an 'argument' between two students about whether a position is checkmate. The presented solution: a variety of software/hardware that will make it easier to 'referee' the position. This is ridiculous. When two students are having an argument, figuring out whether there is checkmate on the board is usually the easiest problem to solve. Getting the students to calm down and be good sports is the hard part.

In addition, there is no shortage of adjudication at tournaments. One or two coaches can easily handle the problems of 300+ students in a tournament. We don't need legions of people equipped with apps to go watch children's games. To make the article even more irrelevant, most tournaments across the world are run with a "non-interference" rule. This means that the tournament staff cannot actually comment on whether a position is checkmate. It is up to the students to come to a decision on their own, agree and report. The coaches with let them report an incorrect result if that is what they agree on. It is part of the game. So the coach doesn't actually need to know whether the position is really checkmate.

The only time an actual ruling needs to be passed is if the students can't come to an agreement. This is very rare and will usually only happen 1 in 2000 games or so. We don't need to RDIF tag all of our 16000+ tournament pieces just so that 1 in 2000 games someone who knows nothing about chess can make an accurate ruling. We'll just bring over an expert in those cases.

A quick aside to those questioning the benefits of K-5 chess, it is hugely beneficial to students. Sure, it would be great if they spent the time they did on chess on other things, like algorithms or biology. However, most students don't get super worked up about algorithms. They aren't going to willingly spend 15 hours a week on algorithms. They will happily spend that time on chess however, and chess is teaching them a lot of the same skills. Critical thinking, carefulness, perseverance, recovering from mistakes, cause and effect, and on, and on.

The most important skill that students learn is how much effort you have to put into something in order to really become an expert. Nothing else a child does in their K-12 years really teaches them that in order to be an expert, you need to spend years and years working on it. Chess is very good at driving this point home.

Anyone saying things like "every minute playing chess would be better spent learning about algorithms, computer programming, or biology." has clearly never sat a kindergartener down and try to teach them algorithms. Every day. For a year. Teach them chess. They will grasp it. They will want to learn. It is fun. They will gain skills that you wouldn't be able to impart in other ways.

But you don't need to take my word on it. The benefits of chess have been have been well studied. Scholastic chess is one of the few things that has been proven to consistently increase academic performance, collage success and future income.

Comment Re:Key Point Missing (Score 2) 34

The summary misses a key point. Yes they scan and store the entire book, but they are _NOT_ making the entire book available to everyone. For the most part they are just making it searchable.

Agreed that it's not in the summary, but as you correctly note, it's just a "summary". Anyone who reads the underlying blog post will read this among the facts on which the court based its opinion: "The public was allowed to search by keyword. The search results showed only the page numbers for the search term and the number of times it appeared; none of the text was visible."

So those readers who RTFA will be in the know.

Submission + - Appeals Court finds scanning to be fair use in Authors Guild v Hathitrust

NewYorkCountryLawyer writes: In Authors Guild v Hathitrust, the US Court of Appeals for the Second Circuit has found that scanning whole books and making them searchable for research use is a fair use. In reaching its conclusion, the 3-judge panel reasoned, in its 34-page opinion (PDF), that the creation of a searchable, full text database is a "quintessentially transformative use", that it was "reasonably necessary" to make use of the entire works, that maintaining maintain 4 copies of the database was reasonably necessary as well, and that the research library did not impair the market for the originals. Needless to say, this ruling augurs well for Google in Authors Guild v. Google, which likewise involves full text scanning of whole books for research.
