Developers Get Qt | LINUX Unplugged 40

We chat with two of the LXQt developers, and find out what’s behind this major undertaking. Then we discuss our favorite packages for a Linux home server, and the brand new Ubuntu Orange cluster box.

Plus your feedback, our follow up, and much more!

What makes the perfect home server?

Round Table:

Anti-virus pioneer Alan Solomon thinks anti-virus is dead. He uses Linux instead

“I stopped using an antivirus a long time ago, because I couldn\’t see how it could work in a world where you would need daily updates, which means that each update is tested for … how long? Not very long, obviously.

Ubuntu Cluster Orange Box

The Orange Box is an innovative, custom designed micro cluster chassis, envisioned by Canonical, and contract manufactured by TranquilPC Limited. The chassis includes a small cluster of Intel NUC (Next Unit of Computing) boards, and is particularly well suited for portable demonstration and local prototyping of cloud workloads. The Orange Box, manufactured in the UK to exacting standards is available to order and ships internationally (free of charge).

Each Orange Box chassis contains:

  • 10x Intel NUCs
  • Specifically, the Ivy Bridge D53427RKE model

Each Intel NUC contains

  • i5-3427U CPU
  • Intel HD Graphics 4000
  • 16GB of DDR3 RAM
  • 120GB SSD root disk
  • Intel Gigabit ethernet
  • D-Link DGS-1100-16 managed gigabit switch with 802.1q VLAN support

All 10 nodes are internally connected to this gigabit switch

In aggregate, this micro cluster effectively fields 40 cores, 160GB of RAM, 1.2TB of solid state storage, and is connected over an internal gigabit network fabric. A single fan quietly cools the power supply, while all of the nodes are passively cooled by aluminum heat sinks spanning each side of the chassis.

The first node, node0, additionally contains:

  • An Intel Centrino Advanced-N 6235 WiFi adapter
  • A 2TB HDD (spinning)
  • USB and HDMI ports are wired and accessible from the rear of the box
  • Access to the USB/HDMI of nodes1-9 is accessible from the underside of the unit

  • Six GBE LAN ports (all connected to the internal switch) are exposed to the rear panel, for external access, or even clustering of multiple Orange Boxes together.
