NVIDIA Fixes Old Compiz Bug 43

Posted by timothy
from the mayan-long-count dept.
jones_supa writes NVIDIA has fixed a long-standing issue in the Ubuntu Unity desktop by patching Compiz. When opening the window of a new application, it would go black or become transparent on NVIDIA hardware. There have been bug reports dating back to Ubuntu 12.10 times. The problem was caused by Compiz, which had some leftover code from a port. An NVIDIA developer posted on Launchpad and said the NVIDIA team has been looking at this issue, and they also proposed a patch. "Our interpretation of the specification is that creating two GLX pixmaps pointing at the same drawable is not allowed, because it can lead to poorly defined behavior if the properties of both GLX drawables don't match. Our driver prevents this, but Compiz appears to try to do this," wrote NVIDIA's Arthur Huillet. The Compiz patch has been accepted upstream.

Hillary Clinton Used Personal Email At State Dept., Possibly Breaking Rules 285

HughPickens.com writes: The NY Times reports that Hillary Rodham Clinton exclusively used a personal email account to conduct government business as secretary of state, according to State Department officials. She may have violated federal requirements that officials' correspondence be retained as part of the agency's record. Clinton did not have a government email address during her four-year tenure at the State Department. Her aides took no actions to have her personal emails preserved on department servers at the time, as required by the Federal Records Act. "It is very difficult to conceive of a scenario — short of nuclear winter — where an agency would be justified in allowing its cabinet-level head officer to solely use a private email communications channel for the conduct of government business," said attorney Jason R. Baron. A spokesman for Clinton defended her use of the personal email account and said she has been complying with the "letter and spirit of the rules."

Google Backs Off Default Encryption on New Android Lollilop Devices 90

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.

How a Kickstarter Project Can Massively Exceed Its Funding Goals and Still Fail 157

Posted by Soulskill
from the optimism-to-a-fault dept.
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 camera 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.

Games Workshop At 40: How They Brought D&D To Britain 50

Posted by Soulskill
from the still-not-over-the-hill dept.
An anonymous reader writes: Following on the fortieth anniversary of Dungeons & Dragons last year, another formative influence on modern gaming is celebrating its fortieth birthday: Games Workshop. Playing at the World covers the story of how the founders, Ian Livingstone and Steve Jackson (not the other Steve Jackson), started out as subscribers to the 1960s British gaming zine Albion playing Diplomacy by mail and (in Ian's case) publishing silly cartoons. When Albion folded at the beginning of 1975, Livingstone and Jackson formed Games Workshop with its own zine Owl & Weasel as a way to bring "progressive games" (as in "progressive rock") to the UK. Shortly thereafter, when they discovered Dungeons & Dragons, fantasy and role-playing games became their focus. After Owl & Weasel grew up into White Dwarf in 1977, its famous "Fiend Factory" column ended up populating the D&D Fiend Folio. And in the 1980s, of course, they brought us Warhammer and their retail stories brought stylish miniatures to many a needful gamer. Happy birthday to Games Workshop!

Astronomers Find an Old-Looking Galaxy In the Early Universe 114

Posted by Soulskill
from the diamond-in-the-old dept.
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.

schwit1 (797399) 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.""

Police Could Charge Data Center Operators In the Largest Child Porn Bust Ever 184

Posted by Soulskill
from the enforcing-due-diligence dept.
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++? 304

Posted by Soulskill
from the not-as-classic-as-COBOL dept.
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.)

New Seagate Shingled Hard Drive Teardown 76

Posted by Soulskill
from the made-out-of-actual-shingles dept.
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.
