Dayton Audio MK402 review: Great stereo speakers for the price of sneakers

The Dayton Audio MK402s offer much more than the sticker price would have you believe: a revealing sound, tight bass and they don't look half-bad sitting on a shelf. The addition of proper binding posts helps make connecting to a stereo even easier. Nothing anywhere near this price offers a package so compelling.

Trump-linked firm Cambridge Analytica harvested data on 50 million Facebook profiles

Grewal said that the social networking giant learned earlier in the week that London-based Cambridge Analytica, used by campaigns to strategically target personalized political messages, and its parent company Strategic Communication Laboratories (SCL), had misused data collected on 270,000 Facebook users. That data, including Facebook profile names, locations, and information on their friends and the content they liked, was collected by a benign-looking personality prediction "research" app, developed by Aleksandr Kogan, a Russian-American researcher and lecturer at the University of Cambridge.

I finally tried a mechanical keyboard. I'm not going back

But a close second reaction was the tactile sensation -- and satisfaction -- of slamming down on the keys. Having spent years on traditional shallow keyboards, it felt like extra work to push mechanical keys all the way down (a term known as actuation force). But after just a few minutes, my fingers were flying and the keys were singing.

Twitter is reportedly planning to ban cryptocurrency ads

In January, Facebook prohibited ads for currencies such as Bitcoin in an effort to combat deceptive marketers, while Google followed suit last week . Sky News says (via Engadget ) that the new advertising policies would ban worldwide ads for ICOs, token sales, and cryptocurrency wallets. The site might also ban ads for cryptocurrency exchanges, but with some possible exceptions. The ban could begin in as soon as two weeks. We’ve reached out to Twitter for comment, and will update this post if we hear back.

Microsoft Windows joins iOS and Android in embracing HEIC, which halves JPEG's photo sizes

HEIF is a big deal since it can free up storage space and help you avoid running into your monthly network data cap. But there's more, too: It's actually a flexible data container that can accommodate live photos, bursts of photos, 3D scene data useful for special effects, audio, and more. In other words, it helps photo formats keep pace with today's changing definition of digital photography.

Shure's $3,000 KSE1500 headphones make for an ear-opening experience

The Shure amp-digital converter build quality feels robust. The headphone's Kevlar-reinforced cable is thicker, stiffer and heavier than most in-ear headphone cables, and it's definitely not user-replaceable. Maximum playtime for the KSE1500's Lithium-Ion battery is 10 hours. The converter's maximum resolution is limited to 96-kHz (24-bit) PCM files -- nowhere as high-resolution as what's available from Astell & Kern or FiiO music players. Shure includes a handsome leather case for the amp-converter.

LeVar Burton wants to read you his favorite short stories

Burton says that podcasting is an ideal medium for encouraging reading and literacy, in part because of its accessibility and convenience — allowing people to listen when it’s best for them. “We all want to customize our content experience, in a way that works for us, and podcasting fits right into that.” Burton also notes that podcasting helps enhance the stories he selects: “What audio storytelling does is it engages the listener in a way that visual storytelling does not. You are creating the visuals for yourself, and because of that additional level of personal investment, it’s enjoyable on a different level.”

9 reasons to be cautious with blockchain | ZDNet

Blockchain efficiency: For starters, he efficiency of blockchains themselves may become overloaded with complex consensus mechanisms and invalid data. Li and his co-authors note that the consensus mechanisms employed across the Internet are computing resource hogs. For instance, most popular consensus mechanism used in blockchain is Proof of Work, which the researchers call a "waste of computing resources." They say there are efforts to develop more efficient and hybrid consensus mechanisms that combine PoW and Proof of Stake (PoS). In addition, blockchains will produce a lot of data -- block information, transaction data, contract bytecode -- that may be outdated and useless. "There are a lot of smart contracts containing no code or totally the same code in Ethereum, and many smart contracts are never be executed after its deployment. An efficient data cleanup and detection mechanism is desired to improve the execution efficiency of blockchain systems."

DroneMax 360 hands-on: A portable power station that does it all | ZDNet

Perhaps more importantly, however, is the peace of mind I have in knowing that if we were to lose power, I have a power station that can charge phones and run a lamp or a small household appliance if needed.

Here are some of the juiciest details from the Theranos suit

The startup also sent investors a binder of background materials including incorporation documents, shareholder agreements, financial projections and news articles about Theranos. One section included reports of clinical trial work Theranos had supposedly done with pharmaceutical companies. These reports prominently displayed these companies' logos, suggesting they were drafted by them. But only one of the reports was co-written by a pharmaceutical client, the suit states. The other two were drafted by Theranos employees, who simply added the pharmaceutical companies' logos to them. These reports led investors to believe the companies had written endorsements of Theranos' technology, the SEC says.

Tinder’s parent company is suing Bumble for patent infringement

On Friday, Match filed a lawsuit that accuses Bumble of infringing on a pair of patents held by Tinder : one called “Matching Process System and Method,” in which users swipe cards and mutually select one another, as well as “Display Screen or Portion Thereof With a Graphical User Interface of a Mobile Device,” which it describes as an “ornamental aspect” of Tinder’s App. The lawsuit also points to similarities between each companies’ apps, and Bumble’s descriptions of “swiping” run afoul of Tinder’s registered trademarks.

'Wrinkle in Time' production designer has feelings about CG

Sometimes visual effects comes in a little bit later in pre-production. In the case of "Wrinkle in Time", [the] visual effects [team] was there at the same time as I was. I try to lay out everything about the look of the movie and illustrate it so that by the time my job is finished at the end of principal photography, visual effects has a really good map of what they're about to do. These things have all been decided and hashed out in pre-production and production while I'm still there, and when it's handed over to visual effects they are carrying it out. That said, in the process of editing the film, some things change -- they might decide to lose a scene, add a scene, abridge a scene, and visual effects may need to step in along the lines of the design that we've already established and add a few things I may not know about.

The Population Bomb Has Been Defused

So far, the prophets of overpopulation have been defeated by technology. But human ingenuity alone can never deliver a final victory in the battle to feed the world -- eventually, population growth will overwhelm the Earth’s ability to provide calories. That’s why in order to put Malthus and Ehrlich finally to rest, a second component is needed -- lower fertility rates. To save both the environment and themselves, humans must have fewer kids.

Cambridge Analytica’s use of Facebook data was a ‘grossly unethical experiment’

The revelations come after a rocky year for the social media company, which confirmed that political ads from companies backed by the Russian government ran on the site, which were seen by more than 10 million people . Facebook says that the information obtained by Kogan was accessed “in a legitimate way and through the proper channels that governed all developers on Facebook at that time,” and that it has “made significant improvements in our ability to detect and prevent violations by app developers,” in the last five years, requiring developers to justify the use of the data that they collect. But this incident highlights a key feature of Facebook, to utilize personal information to deliver specific advertising to individuals, and only goes to underscore a critical weakness in the American electorate: that this information can not only be used to manipulate an election, but it can be obtained relatively easily, with few checks.

Report: 84% of tech CFOs expect business revenues to increase in 2018

The recently passed tax law (formerly known as the Tax Cuts and Jobs Act) will also be a major CFO focus, as 65% of those surveyed said fully understanding its implications was their top tax reform challenge in 2018. And even though the corporate tax rate is being reduced from 35% to 21%, that doesn't mean that all tech companies will come out ahead, David Yasukochi, tax office managing partner and co-leader of BDO's Technology practice, said in the release.

6 tips and tricks to improve battery life of the Galaxy S9, S9 Plus

The Mid setting still provides access to all of your apps, but slows down the processor and adjusts screen resolution and brightness (to name a few). The Max setting is the nuclear option for power saving mode. When enabled, nearly all apps are inaccessible, the fingerprint sensor no longer works, and the processor is slowed down even more. That said, my Galaxy S9 went from an estimated 10 hours and some odd minutes of battery life in regular mode to over 36 hours when Max mode was enabled.

All you will need is a toilet paper or paper towel roll and a pair of plastic or paper cups. And scissors. All you need to do is cut a slot in the toilet paper roll just large enough to fit your iPhone and then cut a hole into the side of each cup just large enough so they fit on each end of the toilet paper roll. Then you can sit back and enjoy the sounds of your crafting skills.
