Spectacular ideas and scenery coming together at Sketching in Hardware, IoT imaginarium hosted at Biosphere2. Always wanted to visit this science site, delighted to be doing it with so many insightful thinkers on hardware, innovation, design and entrepreneurship.

I was very impressed with Biosphere when I toured it. We are going to need that technology for living on Mars and other planets.

This team has started to capture benchmarks in the charms of all the major pieces of software you might want to run in the cloud.

That means you can now spin up a complex web of apps at scale on your candidate cloud, and benchmark the whole system. You can see in a few minutes how your set of apps will perform on that particular cloud.

Juju gives us an incredibly efficient way to deploy and scale and connect software in all the major clouds. It also gives us the ability to encode standardised actions and operations for each piece of software that is charmed. Adding a benchmark to a charm means anyone can verify performance of that software at scale on any cloud, easily.
 
Repeatable, reliable benchmarks are now available with #Juju!
Benchmarking and performance are interesting problems, especially in today's growing cloud-based microservice scene. It used to be a question of “how does this hardware compare to that hardware,” but as computing and service-oriented architectures grow the question has evolved.

This a slightly amazing piece of technology from the Joyent crew, many of whom are the original architects of containers in Solaris. They have a great container system in SmartOS, which of course runs SmartOS really well.

Normally, an OS container has to be the same OS as its host unless you accept the high price of hardware virtualisation. But the Joyent guys managed to add some magic which allows a full Ubuntu system to run in their SmartOS containers, with no virt overhead.

So that's Ubuntu, with no modifications, running on a system without any Linux kernel. Interesting. Fans of dtrace and zfs now get all those goodies and a perfect Ubuntu file system supporting all your favourite packages, tools and apps. And we're happy to support this evil genius in enterprise environments.

Nothing magic. In /boot/ you find System.map for various kernel versions.

This file contains the absolute adresses of kernel functions, like fopen() ...

If you, at startup of a UBUNTU binary, replace these addresses by Solaris adresses, any UBUNTU binary runs, as if it was originally compiled for Solaris.

c041bc90 b packet_sklist
c041bc94 b packet_sklist_lock
c041bc94 b packet_socks_nr
c041bc98 A __bss_stop
c041bc98 A _end
c041c000 A pg0
ffffe400 A __kernel_vsyscall
ffffe410 A SYSENTER_RETURN
ffffe420 A __kernel_sigreturn
ffffe440 A __kernel_rt_sigreturn

WINE is working in the same way. But, of course, has added some extra functions to make Windows .EXE run.

Very simple, all that.

Hackers typically use that to "hook" keyboard sniffers into the system. Byebye passwords!

Have fun!

The official position of the British government, as reported by the Sunday Times in an entirely unattributed fashion, is pure propaganda aimed at distracting attention from its own failings of security and oversight.

Socket activation means LXD can be available without consuming resources, on every system by default. Containers for the people :)
 
LXD 0.11 is now out!

This release brings file templating, systemd socket activation, support for container restart on host reboot and much more!

Real, reproducible benchmarks of real workloads on public clouds... check.

With public infrastructure services now mainstream, the real question isn't if you should be using the cloud, it's which cloud, and for which workloads. A lot of that is policy - contracts, security, jurisdictions. But a lot of it is pure engineering economics - how much bang are you going to get for your buck on each cloud.

cloud-benchmarking.org is a public repository of reproducible benchmarks for popular workloads. It's unusual in that the workloads are defined as usable juju charms; that means you can spin them up from scratch at scale yourself, you can trust that the results will reflect your actual usage, and there are no little gotchas encoded in special images that are hand-tuned and unrealistic. You genuinely can spin up the same topology of services at scale on any cloud you might care about, and verify the results yourself. Then you can share your results and add to the pool of public knowledge about real workload performance across the public infrastructure services.

Awesome, useful work.

Today we launched a much better way to do fast, easy overlay networks for containers. It's called the "fan" and gives you hundreds of free IP addresses for each actual IP address on your cloud VM. The fan is now enabled for testing on Ubuntu on AWS and other clouds... enjoy!

Open switches need open platforms! The exciting thing about opening up a switch with Ubuntu Core is that you get a consistent management experience with an open choice of different network management capabilities from different vendors. Congrats to the Mellanox team on this milestone!
Canonical is delighted to support the launch of the world’s first 25/100 Gigabit open Ethernet-based switch, being introduced to the market today by Mellanox® Technologies, Ltd. (NASDAQ: MLNX). The new switch runs on ‘Snappy’ Ubuntu Core and will offer a new level of flexibility for network environments.   Mellanox is the leading supplier of high-performance, [...]

That looks suspiciously like a Trident II spec sheet... I'll be interested to see what the "Mellanox" chip does.

Security and developer friendliness are the two primary drivers of IOT Magic, and both are central to snappy Ubuntu Core. Delighted to be rocking the new Intel IOT platforms!

MAAS 1.7 is soon to be published into Trusty! This release added a lot of useful functionality, and it is highly recommended that people running large MAAS deployments test the update before it hits the archives. It's recommended to backup your MAAS 1.5 database and configuration, and test MAAS 1.7 on a pilot network environment. While this has been widely tested, additional feedback would be great. Please send any adverse feedback to the maas-devel list before the stable release update is finalised!

This is 'Hana Fusa', and a favourite stop for Claire and me when we're visiting Kyoto. Have to recommend the bacon sandwich. Enjoy the coffee so much that I felt inspired to take a siphon home!
