Astronomers Find an Old-Looking Galaxy In the Early Universe 157

schwit1 tips news that a team of astronomers has studied one of the most distant galaxies ever observed and found puzzling results. The light we're seeing from this galaxy comes from roughly 700 million years after the Big Bang, so on the cosmic scale, it's quite young. But the galaxy appears much older than astronomers expected. Their paper was published today in Nature. At this age it would be expected to display a lack of heavier chemical elements — anything heavier than hydrogen and helium, defined in astronomy as metals. These are produced in the bellies of stars and scattered far and wide once the stars explode or otherwise perish. This process needs to be repeated for many stellar generations to produce a significant abundance of the heavier elements such as carbon, oxygen and nitrogen. Surprisingly, the galaxy A1689-zD1 seemed to be emitting a lot of radiation in the far infrared, indicating that it had already produced many of its stars and significant quantities of metals, and revealed that it not only contained dust, but had a dust-to-gas ratio that was similar to that of much more mature galaxies.

Submission + - How Kickstarter project can massively exceed its funding goals and still fail (medium.com)

An anonymous reader writes: In November, 2013, a Kickstarter project for a software-defined camera trigger scored £290,386 (~$450,000) in funding after asking for a mere £50,000. After almost a year of delays, they've now announced the project is dead. Their CEO has published a lengthy article about how such a successful funding round can still turn into a failed product. In short: budgeting. To get their software into a workable state, they ended up spending 940% of the amount they'd originally allocated to software development. Their protoyping went over budget, too, and they had to spend a fair bit in legal fees to fend off a major lens manufacturer complaining about their product's name. Still, they had more funding than they expected, and would have been able to deal with these costs. Unfortunately, the bill of materials for their final product clocked in way higher than they expected. They would have had to sell the device at about $350 each, when they were originally targeting a $99 price point. (And that figure assumes good sales — with a smaller production run, price per unit goes even higher. The company is now going to refund the remaining money left over from its Kickstarter campaign — about 20% of the total. They're also open sourcing the software and sharing the PCB designs and schematics.

thanks for that information. but other than the mail, none of that is anything they did. they bought out other companies. I mean thats great for them, flickr is a good platform, im sure tumblr as well. but buying a company and innovating are 2 different things.

Most big companies are like this.

Look at Microsoft, their history is full of purchases: Powerpoint, Hotmail, Visio, Dynamics, Skype, Nokia, Bungie,

Police Could Charge Data Center Operators In the Largest Child Porn Bust Ever 199

sarahnaomi sends this report from Motherboard: Canadian police say they've uncovered a massive online file sharing network for exploitative material that could involve up to 7,500 users in nearly 100 countries worldwide. But unlike past investigations into the distribution of child porn, which typically involve targeting suspects individually, police have instead seized over 1.2 petabytes of data ... from a data center responsible for storing the material, and may even attempt to lay criminal charges against its operators, too.

"What we are alleging is occurring is that there are individuals and organizations that are profiting from the storage and the exchange of child sexual exploitation material," Scott Tod, Deputy Commissioner of the Ontario Provincial Police (OPP), told Motherboard at a conference late last month, after speaking to a crowd of defense specialists. "They store it and they provide a secure website that you can log into, much like people do with illegal online gaming sites."

Ask Slashdot: Which Classic OOP Compiled Language: Objective-C Or C++? 407

Qbertino writes: I've been trying to pick up a classic, object-oriented, compiled language since the early 90s, but have never gotten around to it. C++ was always on my radar, but I'm a little torn to-and-fro with Objective-C. Objective-C is the obvious choice if you also want to make money developing for Mac OS X, but for the stuff I want to do, both languages would suffice on all platforms. I do want to start out on x86 Linux, though, and also use it as my main development platform. Yes, I know quite a few other languages, but I want to get into a widespread compiled language that has good ties into FOSS. Both Objective-C and C++ fit that bill. What do you recommend? How do these two programming languages compare with each other, and how easy is cross-platform development in either? (Primarily GUI-free, "headless" applications.)

Submission + - Google Quietly Backs Away From Encrypting New Lollilop Devices by Default

An anonymous reader writes: Although Google announced in September 2014 that Android 5.0 Lollipop would require full-disk encryption by default in new cell phones, Ars Technica has found otherwise in recently-released 2nd-gen Moto E and Galaxy S6. It turns out, according to the latest version of the Android Compatibility Definition document (PDF), full-disk encryption is currently only "very strongly recommended" in anticipation of mandatory encryption requirements in the future. The moral of the story is don't be lazy; check that your full-disk encryption is actually enabled.

New Seagate Shingled Hard Drive Teardown 93

New submitter Peter Desnoyers writes: Shingled Magnetic Recording (SMR) drives are starting to hit the market, promising larger drives without heroic (and expensive) measures such as helium fill, but at a cost — data can no longer be over-written in place, requiring SSD-like algorithms to handle random writes.

At the USENIX File and Storage Technologies conference in February, researchers from Northeastern University (disclaimer — I'm one of them) dissected shingled drive performance both figuratively and literally, using both micro-benchmarks and a window cut in the drive to uncover the secrets of Seagate's first line of publicly-available SMR drives.

TL;DR: It's a pretty good desktop drive — with write cache enabled (the default for non-server setups) and an intermittent workload it performs quite well, handling bursts of random writes (up to a few tens of GB total) far faster than a conventional drive — but only if it has long powered-on idle periods for garbage collection. Reads and large writes run at about the same speed as on a conventional drive, and at $280 it costs less than a pair of decent 4TB drives. For heavily-loaded server applications, though, you might want to wait for the next generation. Here are a couple videos (in 16x slow motion) showing the drive in action — sequential read after deliberately fragmenting the drive, and a few thousand random writes.

Google Prepares To Enter Wireless Market As an MVNO 43

jfruh writes Google is getting into the wireless connectivity business, but that doesn't mean you'll be able to use them as your wireless connectivity provider any time soon. The company isn't building its own cell network, but will rather be a "mobile virtual network operator" offering services over existing networks. Google says it won't be a full-service mobile network in competition with existing carriers; instead, the MVNO will offer a platform through which it can experiment with new services for Android smartphones.

The 1st season of TNG was a mess; it got better afterwards when Gene became less involved and Rick Berman took over. He's really the guy we can thank for TNG being the classic it was. He took Gene's great vision, and made a great show out of it. It also helped when Gene's drinking buddy Maurice Hurley left the show, as he was a writer and had a lot of sway over the scripts. He's the reason Gates McFadden left during the 2nd season.

As for the Federation not being superior, how do you figure? They weren't militaristic, so of course they weren't easily able to easily overcome the Romulans and Klingons who devoted all their resources to empire-building and the military. It's just like Russia today. Their economy sucks but they're still holding onto lots of territory and have lots of power because that territory holds valuable natural resources, and they have a huge and powerful military to guard it and push their agenda, including seizing land from neighboring nations.

Submission + - Astronomers Find a Dusty Galaxy That Shouldn't Exist (nationalgeographic.com)

schwit1 writes: Peering back in time to find the very earliest objects in the universe, an international team of astronomers has discovered a galaxy that shouldn't be there at all.

The problem, the scientists report Monday in Nature , is that while the tiny galaxy dates from just 700 million years or so after the big bang, it's far more dusty than something this young and small has any right to be.

The dusty galaxy is just one of the recent surprises astronomers have found. "Last week," says Marrone, "we learned of an incredibly massive black hole in the early universe. Now we have this average galaxy with significant amounts of dust. We've had this cartoon picture of the early universe, but it's clear that we really don't know what's going on."

BS, TNG was a great series. However, it was really rough and kinda bad during the first season, and into the 2nd.

What worked was when Gene was the figurehead and kinda oversaw things, so that people were working according to his vision, but Gene was not involved in any nitty-gritty details. He was a lot like George Lucas: he came up with some cool ideas and visions for things, but when they were executed by other people is when the final product was really fantastic.

Gene became much less involved in the show after the 2nd season, and that's when it really shined, at least until it just got too old and stale. The 3rd-5th seasons were amazing, and some of the best TV ever made.

The same thing happened in TOS too. All the best episodes were when Gene wasn't so hands-on.

Now with Gene gone, it's gone to crap because they aren't using his vision at all, they're just recycling and trying to make money off of things from the prior series, but without the vision that really made it ST.

I actually like the guy they have playing Bones on the competing fan-made Star Trek Phase II series. The other actors, not so much, but the McCoy guy is great. They should swap him with the Bones guy from ST: Continues, because all their actors are great except for the McCoy guy. My office desk is less wooden.

Great post. I feel mostly the same way, except I never bothered with JJ's 2nd movie because I was too disappointed by the 1st one.

The real problem with Star Trek, however, was that it was unrealistic in its optimism and with everyone having such excellent values. They said many times in the series that genetic engineering was bad, was banned, etc. (except for that 2nd-series Pulaski episode in TNG, for some odd reason), but the only way humanity is going to be that moral is if it's engineered into them, or we do something to engineer sociopathy out of our species. Right now, sociopaths are in charge, and are exceedingly common, and their values permeate our society. Just look at the replies to your post: these days, the only thing that matters is money and profit, that's what makes a person "good". Even the Christians will tell you this these days: God favors people who make more money, and loves rich people more, and poor people are poor because God has abandoned them. Popular TV preachers like Joel Osteen will happily tell you this, and countless Christian churches preach this theology.

Of course, even Star Trek had its dark side, but it was in the past: we were supposed to have the Eugenics Wars back in the 1990s, and we're supposed to have WWIII sometime soon. Only after all that calamity is Zephram Cochrane supposed to invent the warp engine, meet the Vulcans, and quickly propel us into the galactic neighborhood as seen in STE, with humanity going from a war-torn society to eradicating poverty inside a century. So according to ST, we're supposed to be living in a pretty shitty time right now. That seems ridiculously optimistic however (that going through WWIII and meeting the Vulcans will suddenly turn us into a wonderful race of moralistic do-gooders without a bunch of sociopaths running our society like we have now).

What I like to tell people in discussions like this is that Star Trek does show our society, but not in the normal episodes; they're in the "mirror" episodes! That's us: the evil humans who run around murdering and conquering anyone and anything we can. If we ever invent warp drive and phasers, the galaxy is going to wish they only had the Klingons to deal with.
