NetHack: Still One of the Greatest Games Ever Written

M-Saunders writes: While everyone obsesses about frame rates and polygon counts, there’s one game that hasn’t changed visually for decades. NetHack may look incredibly primitive today, but it’s still arguably the best game of all time, with an unmatched level of depth, creativity and replayability. Linux Voice looks at this fascinating dungeon romp, explaining what makes it great, how to get started with it, and how to discover some of its secrets. Read more of this story at Slashdot.

The Fastest Camera Ever Made Captures 100 Billion Frames Per Second

Jason Koebler writes A new imaging technique is able to capture images at 100 billion frames per second—fast enough to watch light interact with objects, which could eventually lead to new cloaking technologies. The camera was developed by a team at Washington University in St. Louis—for the team’s first tests, it was able to visualize laser pulse reflections, photons racing through air and through resin, and “faster-than-light propagation of non-information.” It can also be used in conjunction with telescopes and to image optical and quantum communications, according to lead researcher Liang Gao.

How High-Tech Temporary Tattoos Will Hack Your Skin

Molly McHugh writes with this story about sensors that can be attached to temporary tattoos to monitor various medical information. “The Center for Wearable Sensors at the University of California San Diego has been experimenting with attaching sensors to temporary tattoos in order to extract data from the body. The tattoos are worn exactly as a regular temporary tattoo would be worn. The sensors simply sit atop the skin without penetrating it and interact with Bluetooth or other wireless devices with a signal in order to send the data….A biofuel battery applied as a temporary tattoo converts sweat into energy, and a startup within the center has developed a strip that extracts data from sweat to explain how your body is reacting to certain types of exercise. Amay Bandodkar, a fourth year PhD student at UCSD, explains that the sensors are programmed to react to the amount of lactate the body produces.” Read more of this story at Slashdot.

Windows 10 Adds Battery Saver Feature

jones_supa writes In past builds of Windows 10 Technical Preview there has been an interesting feature called Battery Saver, but for the time being it has been just a mockup. In a leaked build 9888, the code is now in place. Battery Saver, as the name implies, will help your mobile device make the most out of your battery. This feature works by limiting the background activity on your device when the mode is activated. You can turn the feature on any time but there is also a setting to have it automatically turn on when the battery capacity goes below a user-defined percentage. Considering that this build was not supposed to make its way out of Redmond and that the company is not releasing any new builds this year, this may be the best look we get until the Consumer Preview arrives.

IoT Is the Third Big Technology ‘Wave’ In the Last 50 Years, Says Harvard

dcblogs writes: The Internet of Things (IoT) may be more significant in reshaping the competitive landscape than the arrival of the Internet. Its productivity potential is so powerful it will deliver a new era of prosperity. That’s the argument put forth by Michael Porter, an economist at the Harvard Business School and James Heppelmann, president and CEO of PTC, in a recent Harvard Business Review essay. PTC is a product design software firm that recently acquired machine-to-machine firm Axeda Corp. In the past 50 years, IT has delivered two major transformations or “waves, ” as the authors describe it. The first came in the 1960s and 1970s, with IT-enabled process automation, computer-aided design and manufacturing resource planning. The second was the Internet and everything it delivered. The third is IoT. That’s a strikingly sweeping claim and there will no doubt be contrarians to Porter and Heppelmann’s view. But what analysts are clear about is that IoT development today is at an early stage, perhaps at a point similar to 1995, the same year Amazon and eBay went online, followed by Netflix in 1997 and Google in 1998. People understood the trend at the time, but the big picture was still out of focus. Read more of this story at Slashdot.

You’re Doing It All Wrong: Solar Panels Should Face West, Not South

HughPickens.com writes In the U.S., a new solar project is installed every 3.2 minutes and the number of cumulative installations now stands at more than 500, 000. For years, homeowners who bought solar panels were advised to mount them on the roof facing south to capture the most solar energy over the course of the day. Now Matthew L. Wald writes in the NYT that panels should be pointed west so that peak power comes in the afternoon when the electricity is more valuable. In late afternoon, homeowners are more likely to watch TV, turn on the lights or run the dishwasher. Electricity prices are also higher at that period of peak demand. “The predominance of south-facing panels may reflect a severe misalignment in energy supply and demand, ” say the authors of the study, Barry Fischer and Ben Harack. Pointing panels to the west means that in the hour beginning at 5 p.m., they produce 55 percent of their peak output. But point them to the south to maximize total output, and when the electric grid needs it most, they are producing only 15 percent of peak. Read more of this story at Slashdot.

The Cashless Society? It’s Already Coming

HughPickens.com writes Damon Darlin writes in the NYT that Apple pay is revolutionary but not for the reason you think. It isn’t going to replace the credit card but it’s going to replace the wallet — the actual physical thing crammed with cards, cash, photos and receipts. According to Darlin, when you are out shopping, it’s the wallet, not the credit card, that is the annoyance. It’s bulky. It can be forgotten, or lost. “I’ve learned while traipsing about buying stuff with my ApplePay that I can whittle down wallet items that I need to carry to three”: A single credit card, for places that have not embraced, but soon will, some form of smartphone payment; a driver’s license; and about $20 in cash. Analysts at Forrester Research estimate that over the next five years, US mobile payments will grow to $142 billion, from $3.7 billion this year. “If I were to make a bet, I’d say that 10 years from now the most popular answer from young shoppers about how they make small payments would be: thumbprint. And you’ll get a dull shrug when you ask what a wallet is.” Read more of this story at Slashdot.
