Comment Obligatory car analogy (Score 1) 150

You have asked "What is the best car I could buy? Also, should I build it myself or get one from the showroom?"

As many other posts here suggest, the first question is kind of meaningless without knowing what you want to do with said car. Is it for trips around town? To carry 7 kids? A lean mean street-fightin' machine?

As for the second question, if your budget is $50k, then I suggest neither. You cannot (should not try to) build a general-purpose HPC solution and its infrastructure for that kind of money. If your use-case is not heavily dependent on high-bandwidth data transfer then definitely consider AWS/Google compute/Azure. If you have a very specialized use-case, perhaps a single compute job that was trivially parallelizable with little or no I/O, you could probably put something together for $50k and run it under a desk. But general-purpose HPC is not just a bunch of server units. A high-speed switch between your compute nodes alone could cost that much. A very basic chassis from Dell suitable as a compute node costs around $5k. Stuff it full of memory, 2 or 4 xeons, GPUs if you need them, fast local scratch disk, redundant 10GB network connects... again, you're looking well north of $25k per unit. Not to mention, as others have, you need a climate-controlled room with abundant, reliable and redundant power to put the thing in.

Comment Dell Latitude (Score 1) 385

Lots of comments about Linux on XPS series; I've had up-and-down experiences with hardware build quality with those but what I can solidly recommend is the Dell Latitude series - currently E6540 or the 7000. They're a bit pricey but like the Thinkpad and HP ProBook these are business-oriented machines with great warranty support, and upgradeable parts. And Linux runs just great on them - I write this on a slightly older 6440 with Fedora 21 on it; never had any issues even though Fedora is a relatively "pure" distro that doesn't come with proprietary drivers. I would also recommend Fedora as good mainstream distro for work in the sciences - all the packages you would want to run on a laptop (R/scipy etc) are available as rpms: http://fedoraproject.org/wiki/....

Comment Re:Java (Score 1) 407

Java 7 introduced the Closeable interface and try-with-resources statement to give the programmer every incentive to Do The Right Thing in cases like these, and every good Java programmer I know uses them (see http://mina.apache.org/sshd-pr... for topical example of an SSH client implementing Closeable). True, anyone can code badly but that's not the language's fault and in this case I would hardly say that sloppy mentality is encouraged. A poster above noted that C++98 != C++14. By the same token, Java 1.8 != Java 1.2

Comment Misleading headline (Score 5, Insightful) 402

That's not an article about the high tech warfare behind the Israel-Hamas conflict. It's an article about the alleged use of some pretty run-of-the-mill technology by one side (Hamas) with no reference to the actual sophisticated technology used by the other side (Israel). If the article in itself isn't necessarily so, the phrasing of the headline and the summary here is an attempt to portray this conflict as something other than the massively one-sided affair that it actually is. It's a whitewash pure and simple. I wish both sides would just stop killing each other but seriously, "cloud-based launching software"? So Hamas can launch unguided rockets without having to stand next to them. Sounds pretty nasty compared to sophisticated air defence, MBTs, total air superiority and massed artillery.

Submission Imparting malware resistance with a randomizing compiler

wheelbarrio writes: From an Economist article — inspired by the natural resistance offered to pathogens by genetically diverse host populations, Dr Michael Franz at UCI suggests that common software be similarly hardened against attack by generating a unique executable for each install. It sounds like a cute idea, although the article doesn't provide examples of what kinds of diversity are possible whilst maintaining the program logic, nor what kind of attacks would be prevented with this approach.

Submission The Most Feasible Way to Colonize Space May Be to Print Humans on Other Planets

Jason Koebler writes: Adam Steltzner, the lead engineer on the NASA JPL's Curiosity rover mission, believes that to send humans to distant planets, we may need to do one of two things: look for ways to game space-time—traveling through wormholes and whatnot—or rethink the fundamental idea of "ourselves."
"Our best bet for space exploration could be printing humans, organically, on another planet," said Steltzner.

Submission Google discriminates in favour of Asian employees - or what? 2

Bruce66423 writes: http://www.theguardian.com/tec...
The Guardian — a left wing newspaper — has a headline to this article that focuses on the absence of women and especially blacks. But given the 30% Asian headcount, it's dubious this is a function of discrimination against blacks, but that's how the left likes to portray it.

It's easy when you know how to spot the biases...

Submission Conformal Systems' Bitcoin Implementation Goes Beta

An anonymous reader writes: After a year of developement, Conformal Systems has announced that btcd, an alternative full-node bitcoin implementation written in Go, has entered the beta stage. Two great features that I personally love is the ability to use websockets to receive instant notifications of certain events and their client API which works against both btcd and bitcoind. Are mulitple implementations a good thing for the bitcoin community?

Submission Iranian Hacker Group Created Fake News Organization for Social Engineering->

itwbennett writes: A suspected Iranian hacker group seeded Facebook and LinkedIn with bogus profiles of attractive women and even created a fake online news organization to get digitally closer to more than 2,000 U.S. military members, defense contractors and lobbyists it wanted to spy on, according to a report by security consultancy iSight Partners. The group is suspected to be in Iran, based on their working patterns and the location of their command-and-control infrastructure, said Patrick McBride, vice president of iSight's marketing and communications. Their activity is consistent with government-sponsored espionage campaigns, but 'we don't have anything specific tying them back to the government,' he added.

Did you actually what I wrote? Do you know what moral equivalence is? Hint: it's what you're peddling. At what point do I suggest there is any high ground to be had here, by anyone? The reason I can judge Russia's actions critically is the same reason I judged America's actions critically when they invaded Iraq in 2003. It's called intelligence, and partisanship doesn't play any part in it. I'm not even American.
