MicroSD Card Quality Makes a Massive Difference in Raspberry Pi Performance

When you’re putting together your Raspberry Pi projects, you likely just grab whatever microSD card is on sale without thinking much about it. However, over on Midwestern Mac, they did speed comparison between cards, and found a big difference in performance.

Testing over a dozen cards, they found that the card’s speed drastically affected performance, with cheaper cards performing significantly slower than name brand ones. The winner, when cost is factored in, was the Samsung EVO+ Class 10 card, which typically comes in around $10. If you’re interested in the testing methods and some more details, head over to Midwestern Mac. Obviously this isn’t entirely comprehensive, but it covers the bases well enough considering how cheap microSD cards are these days. It sounds like the Samsung EVO and EVO+ cards are you best bet when you’re out shopping for a card for your Pi.

Scientists show that gene editing can 'turn off' human diseases

Gene editing has already been used to fight diseases, but there's now hope that it might eliminate the diseases altgether. Researchers have shown that it's possible to eliminate facial muscular dystrophy using a newer editing technique, CRISPR (Clusters of Regularly Interspaced Short Palindromic Repeats) to replace the offending gene and 'turn off' the condition. The approach sends a mix of protein and RNA to bind to a gene and give it an overhaul.

Raspberry Pi's latest computer costs just $5

Source: http://www.engadget.com/2015/11/26/raspberry-pi-zero/

Over the years, the Raspberry Pi Foundation has enabled universities and hobbyists to create their own DIY computing projects with its affordable boards. But that doesn't mean it's stopping there. Today, the company unveiled its latest programmable computing board, the Raspberry Pi Zero, and it costs just $5 (£4). With its Broadcom BCM2835 application processor (1GHz ARM11 core), 512MB of RAM, a microSD card slot, a mini-HDMI socket supporting 1080p (at 60 frames per second), micro-USB sockets and an identical pin layout to its larger Pi siblings, the Zero can do plenty of heavy lifting, despite its tiny size. For context: at 65mm x 30mm, it's smaller than a credit card and has 40-percent faster chip than the first ever Pi.

Dell is the latest PC maker with a gaping security flaw (update: solution)

Source: http://www.engadget.com/2015/11/23/dell-security-key-flaw/

Dell XPS 15

Lenovo and Samsung might not be the only big Windows PC makers pre-installing software that compromises your security. Computer buyers have discovered that Dell is shipping at least some PCs (such as the new XPS 15) with a self-signed security certificate that's the same on every system. If intruders get a raw copy of the certificate's private key, which isn't hard, they have an easy way to attack every PC shipping with this code. The kicker? This is much like Lenovo's Superfish exploit, only written by the hardware vendor itself -- Dell had plenty of time to learn from its rival's mistake.

Apple and Microsoft's advocacy group is against encryption backdoors

Source: http://www.engadget.com/2015/11/23/itic-encryption-backdoor/

Following Tim Cook's lead, the advocacy group behind Apple, Google, Microsoft and plenty of other big tech firms has come out against calls to weaken encryption, which authorities argue would make it easier to track criminals. "Weakening encryption or creating backdoors to encrypted devices and data for use by the good guys would actually create vulnerabilities to be exploited by the bad guys," said Dean Garfield, the CEO of the Information Technology Industry Counsel (ITIC), who also represents Facebook, Twitter and AOL. It "would almost certainly cause serious physical and financial harm across our society and our economy," he added. The backlash against strong encryption is particularly heated today, following the recent Paris attacks. While secure communications are generally a good thing for consumers, governments (including the US and UK) have argued for backdoors that would allow them to intercept encrypted data. Naturally, that would make life easier for intelligence agencies, but it defeats the point of having encryption at all.

Google buys Fly Labs, Photos to get in-app video editing

Source: http://www.engadget.com/2015/11/06/google-gets-fly-labs-photos-gets-in-app-video-editing/

The team at Fly Labs announced on Friday that Google had acquired their company and will be rolling their image-editing technology into Google Photos. "We'll be pouring the same passion into Google Photos that we poured into Clips, Fly, Tempo and Crop on the Fly," the company wrote in a blog post. Existing users should note that while Fly Lab's existing suite of tools will remain free and available in the App Store for the next three months or so, there will be no more updates. Furthermore, if you've already downloaded the apps, they'll continue to work even after this three-month grace period. You won't, however, be able to re-download them once they've been removed from the App Store so make sure you don't go accidentally uninstalling them.

Explore New Zealand's 'Great Walks' with Google Street View

Source: http://www.engadget.com/2015/11/05/google-street-view-new-zealand-great-walks/

If you want to take a trip to Middle Earth tonight but don't have a passport, Google's got you covered with a new addition to Street View. The internet juggernaut's partnered with New Zealand's Department of Conservation to use Google Trekker to create some pretty rad 360 degree panoramas of the country's most stunning vistas, the "Great Walks." It isn't the first time Mountain View's gone someplace that inspired a movie before, and hopefully it won't be the last. The real question here is if that's an ent moot off in the distance or just your eyes playing tricks on you.

Sony's A7 II camera gets a faster and more accurate autofocus

Source: http://www.engadget.com/2015/11/04/sony-a7-ii-firmware-update/

The Sony A7 II is one of the best mirrorless cameras available right now, although it isn't perfect. After trying it out earlier this year, one of our main issues with the full-frame shooter was its autofocus performance, which was at times slow and unreliable. But Sony has an update coming soon that, along with bringing a new feature, promises to fix some of these woes. In addition to activating the phase detection AF on the A7 II, the company's also turning on support for uncompressed 14-bit RAW image capture -- something that already exists in models such as the A7S II, A7R II and RX1R II. You can grab the refreshed firmware, version 2.0, on November 18th from Sony's support website.

LG Watch Urbane 2nd Edition LTE

If you've wanted a smartwatch that could take its own calls without having to use a separate phone number, relief is in sight... as long as you're willing to subscribe to AT&T, anyway. The carrier has revealed that it will start taking orders for its first two NumberSync-capable smartwatches, the LG Watch Urbane 2nd Edition (above) and Samsung Gear S2, on November 6th. The LTE-equipped LG watch will ship first, arriving in stores on November 13th for either $15 per month (on a 20-month plan) or $200 on a contract. The 3G-based Gear S2 will cost you the same amount when it arrives a week later, on November 20th. You'll still have to tack on $10 per month to your shared data plan to get either watch online, but that could be worth it if you no longer have to worry about missing conversations when you leave your phone at home.

FreedomPop is building a 'WiFi-first' smartphone with Intel

Source: http://www.engadget.com/2015/11/03/freedompop-intel-smartphone-2016/

Budget carrier FeedomPop has signed a deal with Intel that will see it introduce a "WiFi-first" smartphone next year. The phone will use Intel's low-cost "SoFIA" Atom x3 processors and leverage WiFi hotspots wherever possible instead of mobile data, even for things like texting and calling. The phone will "seamlessly" switch between WiFi and cellular networks with no discernible difference to the user, and when it does connect to cellular it'll apparently be free. FreedomPop already offers a similar service -- its big selling point is that calls and texts are sent via mobile data or WiFi rather than traditional means -- but this will be the first phone purpose-built for its virtual network.

This Dramatic High-Speed Drone Chase Is Actually a Demo of MIT's Self-Flying UAV

UAVs are great, but most of them are also dumb as a sack of batteries and plastic. So dumb, in fact, that they have a whole chapter of YouTube devoted to their crashes. But a PhD student at MIT thinks he’s figured out a way to give them brains–or the next best thing.

A Simple Filter Change Could Make Low-Light Photography Much Better

Good low-light photography is one of the toughest nuts to crack: to get good pictures in the dark normally requires some combination of fast lenses and big, expensive sensors. But tweaking one filter that lives inside the camera could help big time.

Tor Messenger makes chatting off the record easier

Source: http://www.engadget.com/2015/10/30/tor-messenger-beta/

Security concept, encrypted binary code with encrypt word inside

Tor has finally released a beta version of the cross-platform chat program it's been working on for quite a while. The client works with several chat services/protocols such as Jabber, IRC, Google Talk, Facebook Chat, Twitter and Yahoo, but its main draw is definitely the privacy features Tor is famous for. It uses Off-the-Record (OTR) protocol to encrypt your IMs, which pass through Tor's network of volunteer computers for security and anonymity. According to Wired, it even has chat logging disabled as a default setting. "With Tor Messenger, your chat is encrypted and anonymous... so it is hidden from snoops, whether they are the government of a foreign country or a company trying to sell you boots," Kate Krauss, the company's public policy director, told the publication.

Picobrew takes a stab at automated counter-top homebrew beer

Source: http://www.engadget.com/2015/10/26/picobrew-takes-a-stab-at-automated-counter-top-homebrew-beer/

PicoBrew is hoping to do for homebrewed beer what Keurig has done for coffee. It tried previously with the Zymatic, but the $2,000 price tag, intimidating size and complexity limited its appeal. Really the Zymatic ended up being for professional brewers to experiment on and for people with deep pockets looking to dip their toe into homebrewing with the least amount of effort possible. The company's new machine, the Pico attempts to address some of those hurdles. First, off, it's dropped the price dramatically. If you move quickly to pick it up through the Kickstarter campaign launching today it will only cost you $500, though it will climb to $1,000 at retail. Second the Pico is roughly half the size of the Zymatic, and can actually fit on an average counter-top. Though, does still take up a significant amount of space and probably wouldn't find a permanent home next to your coffee machine.
