You do not see trackballs every often anymore; new product launches even less. There are a group of users who will be very interested in this updated trackball from Logitech, either due to personal preference or a run in with carpal tunnel they never wish to repeat. The trackball sits on a magnetic base plate with a pivot point that allows you to tilt the body up to 20o for greater comfort. Logitech added basic Bluetooth connectivity in addition to their proprietary driver and dongle for those who do not wish yet another USB port occupied as well as switching to a rechargeable battery. If you want to know more about what has been added, you can read The Tech Report's full review here.
"It's been seven years since Logitech released a new trackball into the world. Join us to find out what Logitech has learned with time and whether it's kept up with some new blood."

Rivet Networks has a new Killer Networking product, but it isn't a line of NICs or Wireless adapters; it's actually a combination of both interfaces (including a minimum of three Gigabit Ethernet ports) that combine to turn your PC into switch and a Wi-Fi extender. They call the new product Killer xTend, and Rivet Networks has partnered with MSI and GIGABYTE to bring the new technology to market.
"Killer xTend delivers powerful network extension capabilities to your computer by integrating a network switch that includes at least three Killer Ethernet ports and using a Killer Wireless-AC module as a Wi-Fi extender. This allows your computer to share its network access with other nearby wired and wireless devices with a strong, powerful network connection.
Consumers no longer need to mess with switches and network extenders that are expensive and difficult to configure. Instead, they can use Killer’s innovative new xTend Technology to connect devices such as gaming consoles, smart phones and tablets directly to their gaming PCs. Killer xTend keeps your games, voice, and video fast and smooth because high priority traffic on the Killer PC is prioritized above the traffic from connected devices. Killer xTend also delivers amazing speeds – with potential throughput up to 1 Gbps for each Killer E2500 plus another 867 Mbps for the Killer Wi-Fi module."
The first motherboard launching with Killer xTend is the MSI Z270 GODLIKE GAMING, with three Killer E2500 NICs and a Killer Wireless-AC 1535 module onboard.
"...the new GODLIKE adapts the Killer™ xTend technology as well and delivers powerful network extension capabilities by integrating a network switch that includes 3 Killer Ethernet ports and a Killer Wireless-AC module as a Wi-Fi extender. This allows the GODLIKE GAMING to provide the network access to other nearby wired and wireless devices with a strong, powerful network connection. Gamers no longer need to mess with switches and network extenders that are expensive and difficult to configure – instead they can use Killer’s innovative new xTend Technology to connect devices such as gaming consoles, smart phones, and tablets directly to your gaming PC. The Killer xTend keeps your games, voice, and video fast and smooth because high priority traffic on the Killer PC is prioritized above the traffic from connected devices. Killer xTend also delivers amazing throughput to your home – with potential throughput up to 1 Gbps for each Killer E2500 plus another 867 Mbps for the Killer Wi-Fi module."
GIGABYTE's AORUS Gaming Series will include Killer xTend, though no specific models were mentioned in the press release from Rivet Networks.

Introduction and Specifications
The G533 Wireless headset is the latest offering from Logitech, combining the company’s premium Pro-G drivers, 15-hour battery life, and a new, more functional style. Obvious comparisons can be made to last year’s G933 Artemis Spectrum, since both are wireless headsets using Logitech’s Pro-G drivers; but this new model comes in at a lower price while offering much of the same functionality (while dropping the lighting effects). So does the new headset sound any different? What about the construction? Read on to find out!
The G533 exists alongside the G933 Artemis Spectrum in Logitech’s current lineup, but it takes most of the features from that high-end wireless model, while paring it down to create a lean, mean option for gamers who don’t need (or want) RGB lighting effects. The 40 mm Pro-G drivers are still here, and the new G533 offers a longer battery life (15 hours) than the G933 could manage, even with its lighting effects disabled (12 hours). 7.1-channel surround effects and full EQ and soundfield customization remain, though only DTS effects are present (no Dolby this time).
What do these changes translate to? First of all, the G533 headset is being introduced with a $149 MSRP, which is $50 lower than the G933 Artemis Spectrum at $199. I think many of our readers would trade RGB effects for lower cost, making this a welcome change (especially considering lighting effects don’t really mean much when you are wearing the headphones).Another difference is the overall weight of the headset at 12.5 oz, which is 0.5 oz lighter than the G933 at 13 oz.

Forget LiFi, Firefly uses infrared lasers to transmit data and torture acronyms. Researchers out of Penn State, backed by Microsoft, are working on a way to get rid of the wiring in your server room and replace it with IR lasers and mirrors; hold the smoke. By using multiplexed beams, they have created a proof of concept test which allows bi-directional data streams at 10 gigabits per second though there is some work to be done before it is ready for a full test.
The mirrors would be MEMs controlled, ensuring that the signal should theoretically be able to reach any receiver, even ones obscured by other equipment. Anyone sick of cable management or looking for new ways to keep people out of the server room can take a peek at the link to the research that The Register posted. On the other hand, the simple act of walking into your server room, setting down a box or even a leaf on the wind would be likely to cause downtime. Could protective goggles might be the newest sysadmin fashion faux pas?
"Shown off at Photonics West 2017 in San Francisco, Firefly (acronymically tortured out of Free-space optical Inter-Rack nEtwork with high FLexibilitY, we kid you not) proposes FSO to provide multiple 10 Gbps inter-rack links."

Bluetooth has come a long way since the technology was introduced in 1998. The addition of the Advanced Audio Distribution Profile (A2DP) in 2003 brought support for high-quality audio streaming, but Bluetooth still didn’t offer anywhere near the quality of a wired connection. This unfortunate fact is often overlooked in favor of the technology's convenience factor, but what if we could have the best of both worlds? This is where Qualcomm's aptX comes in, and it is a departure from the methods in place since the introduction of Bluetooth audio.
What is aptX audio? It's actually a codec that compresses audio in a very different manner than that of the standard Bluetooth codec, and the result is as close to uncompressed audio as the bandwidth-constrained Bluetooth technology can possibly allow. Qualcomm describes aptX audio as "a bit-rate efficiency technology that ensures you receive the highest possible sound quality from your Bluetooth audio device," and there is actual science to back up this claim. After doing quite a bit of reading on the subject as I prepared for this review, I found that the technology behind aptX audio, and its history, is very interesting.
A Brief History of aptX Audio
The aptX codec has actually been around since long before Bluetooth, with its invention in the 1980s and first commercial applications beginning in the 1990s. The version now found in compatible Bluetooth devices is 4th-generation aptX, and in the very beginning it was actually a hardware product (the APTX100ED chip). The technology has had a continued presence in pro audio for three decades now, with a wider reach than I had ever imagined when I started researching the topic. For example, aptX is used for ISDN line connections for remote voice work (voice over, ADR, foreign language dubs, etc.) in movie production, and even for mix approvals on film soundtracks. In fact, aptX was also the compression technology behind DTS theater sound, which had its introduction in 1993 with Jurassic Park. It is in use in over 30,000 radio stations around the world, where it has long been used for digital music playback.
So, while it is clear that aptX is a respected technology with a long history in the audio industry, how exactly does this translate into improvements for someone who just wants to listen to music over a bandwidth-constrained Bluetooth connection? The nature of the codec and its differences/advantages vs. A2DP is a complex topic, but I will attempt to explain in plain language how it actually can make Bluetooth audio sound better. Having science behind the claim of better sound goes a long way in legitimizing perceptual improvements in audio quality, particularly as the high-end audio industry is full of dubious - and often ridiculous - claims. There is no snake-oil to be sold here, as we are simply talking about a different way to compress and uncompress an audio signal - which is the purpose of a codec (code, decode) to begin with.

On the high-end audio side of things Audio-Technica has added to its wireless headphone lineup with both on-ear and in-ear models featuring aptX technology for high quality Bluetooth audio.
ATH-DSR9BT and ATH-DSR7BT headphones
The high-end ATH-DSR9BT and ATH-DSR7BT are Audio-Technica's first wireless headphones with their new Pure Digital Drive system:
This new technology keeps the audio signal completely digital from the audio source to the headphones’ drivers, without the need for D/A conversion stages that typically degrade the sound quality. Traditionally, the digital signal goes through a series of steps that process and transform the wireless signal. This presents several opportunities for distortion in audio quality. Our Pure Digital Drive technology eliminates the opportunities for disruption and distortion that occur in the conversion stages, providing users with a high-quality listening experience.
SonicFuel ATH-AR3BT headphones
Other new models include a "high-performance/high-value" offering in the SonicFuel ATH-AR3BT on-ear headphones, a compact folding design with a new dynamic driver "to deliver richly detailed sound" that the company says "sets a new value standard for high-performance on-ear wireless headphones" at its $119 MSRP.
ATH-CKS990BT and ATH-CKS550BT in-ear monitors
In-ear options ATH-CKS990BT ($199) and ATH-CKS550BT ($119) in the Solid Bass series feature "Dual Magnetic Field drivers with Multiple-Transition diaphragms for improved sound", and will provide better wireless functionality and better controls than previous models.
All of these new wireless headphones and in-ear monitors will be available this spring.

While attending GDC last week and catching up on the world of VR that will be in our laps this spring and summer, I spent some time with Logitech to learn about the company's latest in gaming hardware. We already told you about the G610 keyboards using Cherry keyswitches but today Logitech is revealing a brand new wireless gaming mouse.
First, I know that a lot of gamers, both those in the professional spaces and those that strive to that level of competition, are going to have concerns about this being a wireless mouse. Logitech believes and has convincing evidence that they have built the best and fastest wireless implementation of any option on the market today. I'll go over some of their testing below, but first let's dive into the mouse itself.
Much to the delight of left handed users and anyone looking for a ambidextrous mouse, the G900 Chaos Spectrum is built for you! The design is balanced on both sides and even has a unique button configuration to permit thumb use for both lefties and righties. I have been mousing with it for the last three days, and as a right handed user, am completely comfortable with the design. As the name implies, the G logo on the mouse is completely controllable with RGB LEDs through the Logitech Gaming Software suite.
On the bottom of the G900 you'll find the on/off switch and sync button. Logitech tells us that you will be able to get at least 24 hours of continuous use out of a single charge of the mouse, 32 hours if you turn off lighting, and charge time is going to be around 2 hours. That's actually very good battery life for a high performance sensor like the PMW3366!
On the front is a micro USB port used for charging, which I'll touch on in a minute. The buttons on the G900 are unique as well, using a new mechanical pivot button design. Logitech claims they were built for "crisp, clean clicks". With the pivot point moved back towards the center of the mouse, engineers were able to reduce the travel distances between the buttons and switches and keep the amount of force required for the click to a minimum.
