Specs for first Intel 3D XPoint SSD: so-so transfer speed, awesome random I/O | Ars Technica
UPDATE 3/25/17 JJW:
The M.2 Optane won’t be readily available until later this year or likely 2018 – but it’s a good space to watch, as in our experience the internal interconnect technology and architecture will surely improve, to catch up with the underlying 3D X-Point silicon technology.

Docker says: “Available for both Windows and Mac” – WTF?
Docker, Please – “Available for both Windows and Mac” Are you kidding?
This reminds me of the legendary line from the Blues Brothers movie:
“We got BOTH kinds of music – Country AND Western!”
Sheesh.
Lame – it’s all based on Linux! And Open Source!
Docker runs natively on Linux – the only way to get it to run on Windows and/or Mac, is to run it inside a VM (Virtual Machine), running Linux. Ahem.
So apparently that’s what this does, although you couldn’t tell by the name, the marketing blurb, nor the description.
DOCKER TOOLBOX
The Docker Toolbox is an installer to quickly and easily install and setup a Docker environment on your computer.
Available for both Windows and Mac, the Toolbox installs Docker Client, Machine, Compose and Kitematic.

Sigh.

Step 1 – back up Vista partitions
[joe@sony ~]$ sudo su

The number of cylinders for this disk is set to 14593.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
