Pixel 2 Beats iPhone X, Galaxy Note 8, and LG V30 in LTE Speed Test Battle

pixel 2 xl vs iphone x vs note 8

Ever since the first 4G LTE markets lit up in the US, we’ve talked about speeds. We talk about speeds because we’re technology nerds who are always in a constant competition with one another. We like to brag about the products we’ve invested in. We like to know that we’ve got the best of the best. We also want you to know it. And again, one way we do that is by showing off speed test results on the regular.

Today, test results provided by Cellular Insights to PCMag should give Pixel 2 owners some new bragging rights, but also Android owners in general over the fancy new, future phone, the iPhone X.

The folks at Cellular Insights setup tests on LTE Band 4 in 2×2 MIMO mode, since Band 4 is pretty common here in the US on carriers like AT&T, T-Mobile, and Verizon. They ran the tests starting with a -85dBm and went until they lost connection or could no longer perform. The tests included the Pixel 2, Galaxy Note 8, LG V30, and the iPhone X in two models. For those not familiar, there are two iPhone X models, one with a Qualcomm modem and another with an Intel modem. All of the Qualcomm phones tested used the company’s X16 modem.

lte speeds pixel 2 vs iphone x

According to the results, when using the same band, channel size, and number of antennas, the Pixel 2 pushed 36% better download speeds than the iPhone X. And that would be the Qualcomm version of the iPhone X, since the Intel model version really can’t compete with any of the phones tested. The Galaxy Note 8 and LG V30 were right there with the Pixel 2, though. Even as the Pixel 2 excelled with a strong connection over everyone, the Note 8 and V30 held a better connection longer.

In addition to showing Android phones wipe the floor with the iPhone X, Cellular Insights also tested the three Android devices on LTE Band 4 in 4×4 MIMO mode. They didn’t include the iPhone X in this test because, well, the Intel version can’t do 4×4 MIMO (lolz). The three Android devices all provided similar results with a good connection in this scenario, but the Pixel 2 did show better with a poor signal.

Why is it that these Android phones, the Pixel 2 in particular, crushed the iPhone X so substantially? It could be that because there is an iPhone X model with an Intel modem that can’t compete with Qualcomm’s modem, that Apple slowed the Qualcomm model. That’s unconfirmed, but PCMag notes in their write-up that “industry sources” assume that to be the case. If true, you’ve got to give it up to Apple – they love slowing sh*t.

Brag it up, boys and girls.

Artificial Intelligence Is Fueling Smarter Prosthetics Than Ever Before

The distance between prosthetic and real is shrinking. Thanks to advances in batteries, brain-controlled robotics, and AI, today’s mechanical limbs can do everything from twist and point to grab and lift. And this isn’t just good news for amputees. “For something like bomb disposal, why not use a robotic arm?” says Justin Sanchez, manager of Darpa’s Revolutionizing Prosthetics program. Well, that would certainly be handy.

Brain-Operated Arm

Capable of: Touching hands, reaching out
Mind-controlled limbs aren’t new, but University of Pittsburgh scientists are working on an arm that can feel. Wires link the arm and brain, so when pressure is applied, a signal alerts the sensory cortex.

Hand That Sees

Capable of: Looking for an opportunity
Researchers at Newcastle University have designed a hand with a tiny camera that snaps pics of objects in its view. Then an AI determines an action. Like, grasp that beer and raise it to my mouth.

The Linx

Capable of: Climbing every mountain
Unlike older lower-limb prosthetics, the Linx can tell when it’s sitting in a chair. At just under 6 pounds, it relies on seven sensors that collect data on activity and terrain, helping the leg adapt to new situations.

Bebionic

Capable of: Making rude gestures
It’s the only prosthetic hand with air-bubbled fingertips—great for typing and handling delicate objects (like eggs). And because individual motors power natural movements, wearers can flip the bird in an instant.

The Michelangelo

Capable of: Painting masterpieces
Whereas many prosthetics have a stiff thumb, Ottobock designed this model with a secondary drive unit in the fattest finger—making it opposable. So it’s easier to hold, say, a paintbrush. Big thumbs up!

The LUKE Arm

Capable of: Wielding lightsabers
Yep, LUKE as in Skywalker. The Life Under Kinetic Evolution arm is the first muscle-­controlled prosthetic to be cleared by the FDA. With up to 10 motors in the arm, the Force is definitely with this one.

The best coffee grinder

By Liz Clayton

This post was done in partnership with Wirecutter, reviews for the real world. When readers choose to buy Wirecutter’s independently chosen editorial picks, it may earn affiliate commissions that support its work. Read the full article here.

After more than 65 hours of research and hands-on grinding over the past two years, we think the über-consistent, no-frills Baratza Encore is the best grinder for most people. It reliably delivers the high-quality grind needed to make a great cup of coffee at a practical price for this kind of appliance.

Who this is for

A good grinder makes all the difference in brewing a balanced, flavorful pot of coffee. Photo: Michael Hession

If you consider your morning (or afternoon, or anytime) coffee a serious matter, you’ve likely already heard that the most important item in your brewing setup is a quality burr grinder. Unevenly ground coffee will brew unevenly, yielding a muddied or overly bitter cup. So a good grinder is integral to keeping the most essential part of your brewing technique—the coffee itself—at its most flavorful, and it will ensure the consistency required to produce, and reproduce, that flavor.

How we picked and tested

From left to right: Baratza Encore, Baratza Virtuoso, Porlex Mini Hand Grinder, and Capresso Infinity. Photo: Michael Hession

A quality burr grinder will cost at least $100, which is one reason so many coffee lovers linger in the purgatory of affordable, substandard blade-grinder land. But a good grinder should justify the price: It will last for years with proper maintenance and be easy to clean. It will grind more consistently than a blade grinder, which is the most important aspect of brewing an even, balanced cup of coffee. It should have high-quality, conical burrs made from a hard material like steel or ceramic, and adjusting the grind settings should be straightforward. We also like to see features for controlling dosage, like a timer or a built-in scale, but we don’t think these features are 100 percent necessary.

For this year’s tests, we looked at eight electric models. And because someone will always chime in with the question, "Can’t I just buy a much more affordable hand-grinder?" we also tested a couple of those.

We brought the grinders to the Counter Culture Coffee lab in Manhattan, where Matt Banbury and Ryan Ludwig helped us grind, brew, and taste one of their staple coffees, the Fast Forward blend. They also helped us measure how well the coffee extracted from the grounds, using professional tools such as a refractometer.

Later, we tested our favorite machines in a home setting, to learn about real-world conditions like footprint, noise, ease of use, and speed. Please see our full guide for details about our testing process.

Our pick

The slim and trim Baratza Encore is lower priced than most of the competition—currently at about $140 versus about $200 for anything else in its echelon—and it performs as well as or better than any home grinder we tried. Baratza offers a range of similar grinders with different features and prices, but we found the entry-level Encore to be the best grinder with the best features for most people. It grinds beans quickly and evenly, it’s simple to use, and adjusting the settings is a breeze. It’s also easy enough to clean and maintain that you’ll use it for years to come. Baratza has a great reputation for durability and customer service.

Absent the bells and whistles of nearly all the competitors we tested, the Encore boasts only a modest on/off toggle dial on the side and push-down pulse button on the front of the machine. We don’t see its simplicity as a real drawback, but the inclusion of a timer would have been nice.

Upgrade pick: Baratza Virtuoso

Photo: Michael Hession

If you’re willing to pay more, the Baratza Virtuoso is a nearly identical grinder to the Encore, but it has a slightly speedier burr set, a timer switch on the side, and a heavier base that helps the grinder stay in calibration. We also think it’s a little better-looking than the Encore. In previous years, the Virtuoso was our top pick, but in our recent tests, we found the grind consistency comparable with that of the Encore. So, because you’re paying more for the features rather than the performance, we think it’s only worth the investment for serious coffee lovers.

Budget pick: Capresso Infinity

Photo: Michael Hession

If you really don’t want to spend more than $100 on a coffee grinder, the Capresso Infinity is a great choice. The Infinity did well in our tests, though it’s better at grinding coffee into very fine particles than into coarse ones, and we found the usability a bit arbitrary, with the numbers on its timer switch indicating some duration of time that isn’t seconds. But we liked it for consistency—not as good as our top picks, but better than all the rest—and for the ease of cleaning and maintenance. We also thought it felt sturdier and significantly more durable than any other machine in that price range.

Also great

For those in the market for a truly portable hand-grinder—or a nice forearm workout—we recommend the Porlex Mini. Compared with the other hand-grinder we tested, the Porlex was easier to hold, with smoother and faster hand-cranking action. It’s also made of durable stainless, and fits perfectly inside the chamber of an AeroPress brewer for compact packing. It’s great for travelers or people living off-grid, but because the grind speeds feel glacial, don’t expect to use it as an affordable alternative to an electric grinder, especially if you want to brew more than one cup of coffee at a time.

ZOTAC Unveils AMP Box and AMP Box Mini eGFX TB3 Chassis

ZOTAC has been working on its external chassis for graphics cards with a Thunderbolt 3 interconnection for well over a year now. Apparently, according to ZOTAC, the time it spent was worth it. On Thursday, the company announced not one, but two eGFX TB3 enclosures targeting different audiences and offering different features. The AMP Box is designed for those demanding maximum performance, whereas the AMB Box Mini is aimed at people seeking a quiet and portable solution.


About 1.5 years after the first external chassis for graphics cards with TB3 emerged, the market for such solutions seems to be doing quite well and so it begins to segment into niches. Initially, companies like ASUS, AKiTiO, PowerColor, Razer, and others only offered eGFX boxes for large desktop graphics cards offering maximum performance and consuming a huge amount of power. Then we saw GIGABYTE and GALAX/KFA2 launch rather compact eGFX chassis with pre-installed graphics cards targeting casual users who do not want to assemble anything themselves and do not want and an add-on component that is larger than an SFF PC. Now ZOTAC is releasing two separate solutions (another signal that the market is well established): the AMP Box for DIY enthusiasts that is compatible with high-end graphics cards, and the AMP Box Mini for owners of ZOTAC’s tiny ZBOX computers with a TB3 port as well as everyone who wants a compact eGFX enclosure.



The large ZOTAC’s AMP Box uses aluminum chassis that can accommodate a dual-slot graphics adapter that is up to 228.6 mm (9”) long and with two 8-pin PCIe auxiliary power connectors. It should be noted that most high-end reference graphics cards from AMD and NVIDIA are around 31.2 cm (10.5″) and they are not going to fit into the AMP Box. Therefore, those who plan to use it will have to get “mini” versions of the GPUs from ZOTAC or other manufacturers. To ZOTAC’s credit, it should be noted that the AMP Box is a bit smaller than its competitors from ASUS, AKiTiO or PowerColor. The eGFX TB3 enclosure is equipped with a quad-port USB 3.0 hub (two ports on the front, two on the back, one supports Quick Charging) as well as a 450 W PSU (it is unclear whether we are dealing with a standard, or a custom unit here) to guarantee compatibility with ultra-high-end video cards that need more than “standard” 250 W. Given the wattage of the power supply, it is likely that the AMP Box can also charge a laptop when in use, but the maker has yet to confirm it.



Since the AMP Box was designed for demanding gamers, it is also equipped with ZOTAC’s Spectra programmable RGB lighting so to add some shine to its grey aluminum outfit.



The smaller ZOTAC AMP Box Mini that comes in black metallic chassis only fits in dual-slot add-in-cards that are up to 200 mm (7.87”) long and need a single 6-pin PCIe power connector. The manufacturer proposes to use this enclosure for entry-level graphics cards or even high-capacity SSDs. Considering that ultra-compact form-factor desktops, as well as many notebooks, come with rather mediocre CPUs that are barely designed to run demanding games, mainstream graphics cards will be optimal for such systems. Moreover, those who need to attach a laptop or a tiny desktop to three or four monitors do not need maximum performance in games, so this AMP Box Mini may end up quite popular among such users.



The design of the enclosure is similar to the design of ZOTAC’s MI553 SFF PC, but the box itself is compatible with all of the company’s UCFF systems with a TB3 port, including the CI549 nano, MI549 nano, MI552, and MI572.

Snowden-Backed App ‘Haven’ Turns Your Phone Into a Home Security System

Your digital security, any sufficiently paranoid person will remind you, is only as good as your physical security. The world’s most sensitive users of technology, like dissidents, activists, or journalists in repressive regimes, have to fear not just hacking and online surveillance, but the reality that police, intelligence agents, or other intruders can simply break into your home, office, or hotel room. They can tamper with your computers, steal them, or bodily detain you until you cough up passwords or other secrets.

To help combat that threat, one of the world’s most well-known activists against digital surveillance has released what’s intended to be a cheap, mobile, and flexible version of a physical security system. On Friday, the Freedom of the Press Foundation and its president, famed NSA leaker Edward Snowden, launched Haven, an app designed to transform any Android phone into a kind of all-purpose sensor for detecting intrusions.

Haven uses your phone’s sensors to monitor for changes in sound, light, and movement.

Guardian Project

Safe Haven

Designed to be installed on a cheap Android burner, Haven uses the phone’s cameras, microphones and even accelerometers to monitor for any motion, sound or disturbance of the phone. Leave the app running in your hotel room, for instance, and it can capture photos and audio of anyone entering the room while you’re out, whether an innocent housekeeper or an intelligence agent trying to use his alone time with your laptop to install spyware on it. It can then instantly send pictures and sound clips of those visitors to your primary phone, alerting you to the disturbance. The app even uses the phone’s light sensor trigger an alert if the room goes dark, or an unexpected flashlight flickers.

“Imagine if you had a guard dog you could take with you to any hotel room and leave it in your room when you’re not there. And it’s actually smart, and it witnesses everything that happens and creates a record of it,” Snowden said in an encrypted phone call with WIRED from Moscow, where he has lived in exile since 2013. “The real idea is to establish that the physical spaces around you can be trusted.”

Since he became the director of the Freedom of the Press Foundation in early 2016, Snowden has led a small team of programmers and technologists working on security tools. The results so far range from software that only allows secrets to be decrypted if a group of collaborators combine their secret keys, to a hardware modification for the iPhone that’s designed to detect if malware on the device is secretly transmitting a user’s data.

The ‘Evil Maid’ Problem

The notion of a smartphone-based alarm system arose when Micah Lee, a technologist at the news outlet The Intercept and board member of the Freedom of the Press Foundation, suggested it to Snowden in early 2017. Lee hoped for a new approach to the perennial problem that the cybersecurity community calls the “evil maid” attack: It’s very difficult to prevent someone with physical access to your computer from hacking it.

Eventually, Lee and Snowden’s group of developers at the Freedom of the Press Foundation partnered with the security-focused nonprofit Guardian Project to build and test a software solution to that problem. “We thought, is there a way we can use a smartphone as a security device,” says Nathan Freitas, the director of the Guardian Project. “Take all the surveillance technologies in smartphones and flip them on their head, to keep watch on all the things you care about when you’re not there?”

‘Imagine if you had a guard dog you could take with you to any hotel room and leave it in your room when you’re not there.’

Edward Snowden

In practice, Haven could protect its users from more than just hands-on computer hackers; it could guard against everyone from abusive spouses to authoritarian police. In November, the groups teamed up with the Colombian activism group Movilizatorio to conduct a trial with social justice activists—a group that’s been the target of dozens of assassinations over the last year, in the fallout of tense negotiations between guerrilla groups and the country’s government. Movilizatorio founder Juliana Uribe Villegas says the app provided a key reassurance that month, for a group of 60 testers, that government or criminals agents weren’t breaking into their homes to plant surveillance equipment or, far worse, to kidnap or physically harm them.

“It’s very significant for them to know that they have tools they can use themselves when the government isn’t protecting them,” Uribe Villegas says. “It’s great to think about cybersecurity, but in countries like ours, personal security is still at the top of our list.”

Privacy First

Of course, any device that takes pictures and records audio clips in your home or office and sends them over the internet might sound more like an intolerable privacy violation than a security measure, especially for someone as privacy-sensitive as Snowden, who hasn’t even carried a mobile phone since he first became a fugitive from the US government in 2013.

Haven sends encrypted alerts when activity triggers your phone’s sensors.

Guardian Project

But Haven takes some serious measures to prevent its surveillance mechanisms from being turned against a phone’s owner. It integrates the encrypted messaging app Signal, so that every alert, photo, and audio clip it sends to the user is end-to-end encrypted. As another safeguard, users can also configure Haven to work with the Android app Orbot, which has an option to turn your phone into a so-called Tor Onion Service—essentially, a server on the darknet. That means the Haven phone’s event log can be accessed remotely from your desktop or another phone, but only over Tor’s near-untraceable connection. In theory, that means no eavesdropper can break in to access those audio and photo snapshots of your sensitive spaces.

“Now you can take this huge aggregation of sensors available on any phone today—accelerometers, light sensors, cameras, microphones—and make it work for you and only you,” Snowden says. He notes that despite his personal avoidance of carrying a smartphone, even he has used Haven in hotel rooms while traveling and even at home, albeit only with some additional precautions that he declined to fully detail.

In WIRED’s initial tests of Haven’s beta version, the app successfully detected and alerted us to any attempts to approach a laptop on an office desk, reliably sending photos of would-be evil maids over Signal. If anything, the app was too sensitive to saboteurs; it picked up and alerted us to every stray office noise. The app’s accelerometer detection was so hair-triggered that even leaving the phone on top of a computer with a moving fan inside created hundreds of alerts. You can set thresholds for the audio, but it was tricky choosing a level that wouldn’t trigger false positives. Freitas says the developers are still working on fine-tuning those controls, but that users may have to experiment.

Snowden acknowledges that Haven can’t stop an intruder bent on physically harming someone. But by simply detecting and recording their presence, it might just make them think about the consequences of that intrusion’s documentation, and give victims a significant tool they haven’t had before. “If you’re the secret police making people disappear, Haven changes the calculus of risk you have to go through,” Snowden says. “You have to worry that every possible cell phone might be a witness.”

South Korea fittingly equips high-speed train with high-speed LTE

The Winter Olympics are in South Korea in 2018, which is the perfect excuse to refine old technologies and show off new ones in advance of the huge crowds that will descend on the country early next year. Today, Samsung announced that, in partnership with the Korean telecom company KT, the world’s first LTE-R network on a high-speed train is live.

The new Wonju-Gangneung high-speed train can travel up to 155 miles per hour and is 75 miles long. It was clearly built with the crowds of the Winter Olympics in mind, as the press release states that the train "will provide the public faster, easier access to the largest winter sports facilities in Korea, including PyeongChang." LTE-R will operate across the line’s seven stations, and works with older technologies, such as the Trunked Radio System, VHF systems, and the public safety network (PS-LTE).

LTE-R, or LTE-Railway, is a wireless communication system to connect those operating and working on trains with those on the ground. It allows for fast, reliable communication and signaling, overcoming the challenges of using an LTE network at high speeds. It includes features such as Mission-Critical Push-to-talk, or MCPTT, and a dedicated core network to operate the service.

Samsung is the supplier for five different LTE-R projects in South Korea. The technology is already in place on the Busan Metro line, which was launched in April 2017. This is the first application of the technology to a high-speed train line.

Manchester City signs second FIFA pro as ‘dedicated PS4 player’

Sports teams the world over are adding gamers to their rosters, but it’s particularly common in football. Manchester City FC signed its first eSports pro, Kieran "Kez" Brown, last summer, and today the club’s announced Marcus "ExpectSporting" Jorgensen (aka Marcuzo) has become the second pad warrior to join the squad. Jorgensen previously competed for Danish football club Brøndby IF, with his biggest win to date being the FIFA Interactive Club World Cup held this past August.

Jorgensen’s first start for Man City will be in late January for the FUT Champions Cup in Barcelona. Interestingly, he’s joined the club as its "dedicated PS4 player," which means by default, Kieran Brown will only be seen with an Xbox controller in hand from now on. We didn’t realise the scene has matured to the extent that FIFA players are now platform exclusives, too.
