Increase Your Battery Life with the Latest Laptop Mode Tools

Laptop Mode Tools is a power-saving package for Linux systems, which lets users increase the life expectancy of a laptop’s battery. A new version has been released and is now available for download.

Laptop Mode Tools doesn’t get too many updates, but from the looks of it, there is no need. The application still works even after numerous kernel updates, and the developers only implement small stuff with each new update. It’s quite possible that we’ll see a resurgence in the … (read more)

Ubuntu Developers Working on Feature Parity for Unity 8 – Video

A large part of the work that’s been done for Unity 8 is focused on making it looks and feel like Unity 7. Canonical is not trying to reinvent Unity; it’s rewriting it for the future.

One of the biggest fears expressed by the community is that Unity 8 will look and feel like a mobile experience on the desktop, but that’s not the case. It might seem so right now, but they haven’t got to one of the most important parts, feature parity. Everything that you are seeing and using… (read more)

GPS Navigation for Ubuntu Touch Gets More Features

GPS Navigation is a free app for Ubuntu Touch, and it’s been getting constant updates for the past few weeks. It’s still in the development stages, but it looks like it’s coming together just nicely.

GPS Navigation fills a very important niche in the apps ecosystem for this new platform. Having a working GPS app is really useful, and in this case, it’s with the added bonus of being completely free and based on an open project. You can hardly ask for more.

The developer h… (read more)

Free and Open-Source Video Editor Shotcut Gets Better 4K Support

Powerful video editor Shotcut has been updated again by its developers, and they’ve made some huge improvements to the application. To be fair, pretty much any update for Shotcut is impressive, but this one is an important one.

Users might not know too many things about Shotcut because it is a relatively new application, and only a handful of releases have been made until now. This is also the reason all of the updates released until now have brought so much new stuff; ther… (read more)

Solus OS Gets UEFI Fixes and Better Power Consumption for Laptops

The Solus project is moving very fast, and its developers have managed to push another release out the door, this time with a lot of fixes that have been spotted and repaired in a very short amount of time.

Solus is following a relatively strict schedule, and a stable edition should be landing in a couple of months if nothing out of the ordinary happens. It’s interesting to notice that the devs are still making huge changes to the operating system, like an entirely new Linu… (read more)

4MLinux 13.0 Operating System Has a Highly Customized JWM Experience

DockerCon Europe 2014 - Amsterdam | Friday

Canonical sent three Juju Ecosystem developers and one Juju core developer to Dockercon 2015 in San Francisco during which we participated in a multi-company hackathon team; threw a marketing event featuring industry luminaries; and made connections with many potential charm authors and partners.

We learned loads, preached a lot of good Juju, were impressed what individuals and companies were doing and the collaborative spirit of the event in general. Here’s a bit more detail on what we got up too….

Hackathon

Rancher sponsored a 24 hour hackathon before the conference got underway. This was a really good experience and the grand prize was ticket to the Dockercon 2015 conference (which most of us had already).

Canonical’s Matt Bruzek, Wayne Witzell III and Whit Morriss participated in a pick-up team that included folks from Seed Digital, Capital One, Monsanto, and Michigan.

The idea

The morning of we all ended up sitting at the same table discussing what we were going to work on separately. Whit was blabbing about a talk by Roy Rapoport from Netflix at Monitorama and canaries, OODA loops, and basic metrics for implementing automated canary systems. The group decide to build a dj mixer for doing blue-green releases based on Rapoport’s suggested metrics.

What we built

All the code is hosted under the system-zoo group on GitHub. We created an ec2 environment using Juju, used it to set up some base architecture and provide our team with ssh access to all the machines involved. From the Juju world we used the following charms:

  • Consul
  • Registrator
  • Docker
  • Elasticsearch
  • Heka-hub, Heka-sub

Outside Juju-land, we used Docker to deploy the bits we were hacking up at the moment:

  • cross-fading service aware scala loadbalancer
  • nginx to serve the static content as well as provide the API proxying and service load balancing for Consul, Heka, and ElasticSearch.
  • the test app which had configurable latency and random failure

data-ad-client="ca-pub-1757319933782743"
data-ad-slot="3653493261">

We used Git and GitHub for preserving ad hoc config and used Docker hub for delivering the test app and the load balancer.

What we learned about Juju in this situation

While this an extremely ambitious project, we learned that by standing on the shoulders of giants, we could actually do something that surprised ourselves with almost no prior planning and little prior experience working together. Juju’s ability to rapidly create a secure shared environment populated with mostly working basic required services made a big difference here. Granted, we did not try to set up the same infra using Docker only tools, but under the circumstance, having full machine access made debugging much faster when there were hiccups. We’d recommend folks participating in high time pressure events using Juju, it’s a great way to expose usability warts and other issues.

What we learned in general

Hackathon’s are a great place to meet people, talk shop, and learn what’s happening outside Canonical. The vibe was collaborative, super friendly and it was all around a positive experience both as individuals and Canonical representatives.

Evening of Orchestration

Canonical organized an event the night before Dockercon, it was held at Yelp headquarters. Organizers were Whit Morriss, Randall Ross, Jorge Castro, and Julie Nguyen (from Yelp).

The event was well attended despite not being on the official Dockercon roster and being several blocks away from the official hotel. The venue was great and Yelp was an awesome host. Sam Eaton from Yelp MC’ed the lightning talks which include talks from Yelp, Crate.io, Metaswitch, Clusterhq, Glider Labs, Chuck Butler, and Weave.

We presented a panel of leaders in the orchestration industry including:

  • John Willis (Moderator) from Docker Inc previously Socketplane
  • Adrian Cockcroft from Battery Ventures
  • Ben Saller from Canonical
  • Bill Farner from Twitter
  • Brian Grant from Google who worked on Borg and Omega, now k8s
  • Jeff Lindsay from Glider Labs

Ben did a great job of talking about the principles of Juju and the need for a language for modelling infrastructure to a very positive response from the other panelists and the crowd.

Many people who were taking different approaches to orchestration at a high level, the model that Juju is working to achieve was well received.

Summary

The attitude, the content, the crowd, the production were all impressive. For such a big conference, people were all super friendly and inclusive (from community celebs like Hykes on down). There was a really good overall collaborative community vibe and we were definitely recognized and welcomed coming from Canonical.

Linux Kernel 4.2 RC1 Is One of Biggest Ever Because of New AMD GPU Drivers

Linus Torvalds has revealed that the first Release Candidate for Linux kernel 4.2 has arrived and that it’s one of the biggest ever to land. It’s big because it comes with AMD GPU register description headers, among other things.

The merge window for Linux kernel 4.2 has been opened for a while now. Thus, it was about time to get the first RC, and it looks like it’s going to be a memorable release. Sure, it’s big, and that might stand out, but it also comes with some pretty… (read more)
