Ubuntu Linux 17.04 ‘Zesty Zapus’ Final Beta Now Available For Download

BrianFagioli writes: The final beta of Ubuntu 17.04 ‘Zesty Zapus’ became available for download Thursday. While it is never a good idea to run pre-release software on production machines, Canonical is claiming that it should be largely bug free at this point. In other words, if you understand the risks, it should be a fairly safe. Home users aside, this is a good opportunity for administrators to conduct testing prior to the official release next month. “The Ubuntu team is pleased to announce the final beta release of the Ubuntu 17.04 Desktop, Server, and Cloud products. Codenamed ‘Zesty Zapus’, 17.04 continues Ubuntu’s proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution, ” says Adam Conrad, Canonical. “The team has been hard at work through this cycle, introducing new features and fixing bugs.” Read more of this story at Slashdot.

Rediscovered 1920s Home Movies Are the First to Show the White House in Color

An archivist working at the Herbert Hoover Presidential Library has stumbled upon color home movies taken in the late 1920s by former First Lady Lou Hoover. Incredibly, this is very likely the first color film to show a US President, the First Lady, and the White House. Read more…

Researchers break efficiency record for consumer-friendly solar panels

Turning sunlight into power is a surprisingly tricky thing. Experiments in academia have created solar arrays that can capture up to 40-percent of the sun’s energy and convert it to electricity, but consumer cells are notably less efficient. At best, silicon-based technology has a theoretical 29-percent efficiency ceiling — meaning any consumer panel in the low 20s is doing pretty well. Still, we’re inching ever closer to the technology’s limit. Researchers at Kaneko corp recently announced that they’ve developed a silicon solar cell with a record-breaking 26.3 percent efficiency rating. The score is only just barely higher than the previous record of 25.6, but that 0.7 percent gain is no easy feat. Researchers had to analyze what factors in current cell design was keeping the technology from reaching its theoretical limits. The group decided that reducing optical loss was the best path forward, and moved low-resistance electrodes to the rear of the cell to increase the amount of photons that could be captured. That’s a lot of technical jargon, sure — but the big win here isn’t just that the cell is more efficient, it’s that the more productive silicon cell was produced using the same kind of production process used for consumer sells. In other words, this isn’t just an experiment, it’s something we might actually see on the market soon. Via: Ars Technica Source: Nature Energy

The US Army Finally Gets The World’s Largest Laser Weapon System

It’s been successfully tested on trucks, as well as UAVs and small rockets, according to a video from Lockheed Martin, which is now shipping the first 60kW-class “beam combined” fiber laser for use by the U.S. Army. An anonymous reader quotes the Puget Sound Business Journal: Lockheed successfully developed and tested the 58 kW laser beam earlier this year, setting a world record for this type of laser. The company is now preparing to ship the laser system to the U.S. Army Space and Missile Defense Command/Army Forces Strategic Command in Huntsville, Alabama [according to Robert Afzal, senior fellow for Lockheed’s Laser and Sensor Systems in Bothell]. “We have shown that a powerful directed energy laser is now sufficiently light-weight, low volume and reliable enough to be deployed on tactical vehicles for defensive applications on land, at sea and in the air…” Laser weapons, which complement traditional kinetic weapons in the battlefield, will one day protect against threats such as “swarms of drones” or a flurry of rockets and mortars, Lockheed said.

Microsoft’s Project Scorpio Will Pack Internal PSU, 4K Game DVR Capture

According to an exclusive report from Windows Central, Microsoft’s upcoming “Project Scorpio” gaming console will feature an internal power supply unit (PSU), similar to the Xbox One S, and 4K game DVR and streaming at 60 frames-per-second (FPS). From the report: In Microsoft’s efforts to make Project Scorpio a true 4K system, it will also feature HEVC and VP9 codecs for decoding 4K streams for things such Netflix, just like the Xbox One S. It will also leverage HEVC for encoding 2160p, 60 frame-per-second (FPS) video for Game DVR and streaming. Microsoft’s Beam streaming service has been running public 4K stream tests for some time, and it’s now fair to assume it will not only be PC streamers who will benefit. Project Scorpio’s Game DVR will allow you to stream and record clips in 4K resolution with 60FPS, according to our sources, which is a massive, massive step up from the 720p, 30FPS you get on the current Xbox One. With every bit of information we receive about Project Scorpio, the theme of native 4K keeps appearing — not only for games, but also console features. We now believe Scorpio will sport 4K Game DVR, 4K Blu-ray playback, and 4K streaming apps, but the real showstopper will be the 4K games Microsoft will likely flaunt at E3 2017.

‘We Didn’t Lose Control Of Our Personal Data — It Was Stolen From Us By People Farmers’

Sir Tim Berners-Lee, the inventor of the worldwide web, wrote an open-letter over the weekend to mark the 28th anniversary of his invention. In his letter, he shared three worrisome things that happened over the last twelve months. In his letter, Berners-Lee pointed out three things that occurred over the past 12 months that has him worried: we do not assume control of our personal data anymore; how easy it is for misinformation to spread on the web; and lack of transparency on political advertising on the web. Cyborg rights activist Aral Balkan wrote a piece yesterday arguing that perhaps Berners-Lee is being modest about the things that concern him. From the article: It’s important to note that these (those three worrisome things) are not trends and that they’ve been in the making for far longer than twelve months. They are symptoms that are inextricably linked to the core nature of the Web as it exists within the greater socio-technological system we live under today that we call Surveillance Capitalism. Tim says we’ve “lost control of our personal data.” This is not entirely accurate. We didn’t lose control; it was stolen from us by Silicon Valley. It is stolen from you every day by people farmers; the Googles and the Facebooks of the world. It is stolen from you by an industry of data brokers, the publishing behavioural advertising industry (“adtech”), and a long tail of Silicon Valley startups hungry for an exit to one of the more established players or looking to compete with them to own a share of you. The elephants in the room — Google and Facebook — stand silently in the wings, unmentioned except as allies later on in the letter where they’re portrayed trying to “combat the problem” of misinformation. Is it perhaps foolish to expect anything more when Google is one of the biggest contributors to recent web standards at the W3C and when Google and Facebook both help fund the Web Foundation? Let me state it plainly: Google and Facebook are not allies in our fight for an equitable future — they are the enemy. These platform monopolies are factory farms for human beings; farming us for every gram of insight they can extract. If, as Tim states, the core challenge for the Web today is combating people farming, and if we know who the people farmers are, shouldn’t we be strongly regulating them to curb their abuses?

Proof Daylight Saving Time Is Dumb, Dangerous, and Costly

From a report on Bloomberg: The case for daylight saving time has been shaky for a while. The biannual time change was originally implemented to save energy. Yet dozens of studies around the world have found that changing the clocks has either minuscule or non-existent effects on energy use. The latest research suggests the time change can be harmful to our health and cost us money. The suffering of the spring time change begins with the loss of an hour of sleep. That might not seem like a big deal, but researchers have found it can be dangerous to mess with sleep schedules. Car accidents, strokes, and heart attacks spike in the days after the March time change. It turns out that judges, sleep deprived by daylight saving, impose harsher sentences. Some of the last defenders of daylight saving time have been a cluster of business groups who assume the change helps stimulate consumer spending. That’s not true either, according to recent analysis of 380 million bank and credit-card transactions by the JPMorgan Chase Institute. Read more of this story at Slashdot.

Chrome 57 Arrives With CSS Grid Layout and API Improvements

Google has launched Chrome 57 for Windows, Mac, and Linux. From a report on VentureBeat: Among the additions is CSS Grid Layout, API improvements, and other new features for developers. You can update to the latest version now using the browser’s built-in silent updater, or download it directly from google.com/chrome. Chrome is arguably more than a browser: With over 1 billion users, it’s a major platform that web developers have to consider. In fact, with Chrome’s regular additions and changes, developers have to keep up to ensure they are taking advantage of everything available. Chrome 57 implements CSS Grid Layout, a two-dimensional grid-based layout system for responsive user interface design. Elements within the grid can be specified to span multiple columns or rows, plus they can also be named so that layout code is easier to understand. The goal is to give developers more granular control, especially as websites are increasingly accessed on various screen sizes, so they can slowly move away from complex code that is difficult to maintain.

IBM built an atomic hard drive

While the rush to keep pace with Moore’s Law is getting rather “chaotic” , researchers at IBM announced on Wednesday that they have drastically reduced the space required to store a bit of information down to that of a single atom. This tiny advancement in storage technology, is a big deal. Given that modern hard drives need about 100, 000 atoms to store a single bit, this development could shrink the size of future storage mediums by an order of magnitude. IBM figures that it can store the entire iTunes catalog (all 35 million tracks) onto a disk the size of a credit card by using this technique. A single atom of holmium credit: IBM Research – Almaden The system uses atoms of holmium seated atop a magnesium oxide surface, which keeps the atom’s magnetic poles stable — even in the presence of other magnets. The orientation of these poles determines whether the atom constitutes a 1 or a 0. To write to this storage system, a microscopic needle induces a current to flip the atom’s orientation. Reading the information, conversely, is simply a matter of measuring the magnetic current passing through each atom, which varies depending on which pole is facing up. But don’t expect this technology to show up in the next iPhone, mind you. It currently requires a liquid nitrogen-cooled tunnelling electron microscope operating in a vacuum to work. The study was published today in the journal Nature .
