Razer have made some interesting choices with their Hyperflux wireless mouse and charging mat.  The Mamba Hyperflux does not contain a battery, instead depending on a constant flow of energy from the FireFly Hyperflux powered mouse mat or via the provided USB cable if you want to forgoe the wireless capabilities altogether.  It seems this choice came with a price, Kitguru has seen it for sale at £249.95, the US price at Amazon is a similar number, which makes this quite expensive comparatively.  Is it worth the cost or are you just paying extra for a unique feature?  Check out the video review for Kitguru's thoughts.

"Creating a light gaming mouse has always been a challenge for one simple reason – it needs a battery. That’s what we thought, at least, until Razer introduced its Mamba Hyperflux gaming mouse. It weighs just 96g and simply does not have a battery – instead, it uses magnetic induction to receive power directly, thanks to the use of a supercapacitor."

Microsoft's hot new idea for the server room; IR lasers

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."
