We are pleased to announce that ubermix 4 is finally here! Based on Ubuntu 18.04 (Bionic Beaver), ubermix 4 is the culmination of years of work and experience, with the feedback and support of thousands of users all over the world!

As with prior ubermix releases, ubermix 4 is based on a Long Term Support (LTS) release of Ubuntu, which means that it will receive support and updates from for a full 5 years, through April 2023. LTS releases are the most reliable and stable versions, making them an ideal base to build from. That said, it is time to say goodbye to ubermix 2, as it has just passed its support window. Images will remain available on the ubermix site, however they will no longer be supported or updated.

ubermix 3.23 released!

Posted by Jim Klein On Tuesday, July 4, 2017 1 comments
ubermix 3.23 is out and available for your consideration. With nearly 9 years of active development behind it, ubermix is ready to take on your next generation devices, with strong touch support and updates that make it an excellent choice for both personal and school use.
Here are just a few of the new features of ubermix 3.23:

Touch Support

ubermix now includes hardware support, tools and theming that are designed specifically for touch devices, like the excellent Acer Travelmate Spin B1.

One of the challenges for most operating systems designed for laptops - even Windows - is that they typically run in one of two User Interface (UI) modes: Standard or HiDPI. Standard UI mode is most common for displays with High Definition (HD) resolutions, which typically run 1920×1080 to 2560×1440 on modern hardware. For ultra-high resolution displays, like Apple's Retina and Dell/HP's Quad HD displays running at 3200×1800 or more, the operating system will switch to HiDPI mode, which essentially doubles the size of everything on the screen.

App Spotlight - FeedReader

Welcome to the first in a series of posts about awesome apps you can install on ubermix to make it your own!

If you are like me, you try to keep tabs on a number of news feeds from a variety of sources, using Feedly or some other RSS feed aggregator. And while Feedly's web reader is fine, it's far from spectacular, especially when used on a touchscreen device, like the excellent Acer Switch Alpha 12 or Spin 7 (both great choices for ubermix).

Enter FeedReader.

FeedReader is a standalone RSS reader app for Linux desktops that does a nice job of fetching and organizing feed content. It performs all of the functions you would expect, including marking items as read, starred, tagging, and the like, and will even share articles to your Instapaper or Pocket account. And best of all, it caches content, so you can read offline, should you find yourself without an internet connection.

To check it out, open a terminal (ctrl-alt-t is the fastest way to get to one) and copy and paste the following commands:

sudo add-apt-repository ppa:eviltwin1/feedreader-stable sudo apt-get update && sudo apt-get install feedreader


ubermix 3 now avalable!

Posted by Jim Klein On Friday, June 10, 2016 10 comments
After months of testing, ubermix 3, the latest and greatest version of the popular operating system, has been released into the wild! Based on Ubuntu 16.04 (Xenial Xerus), ubermix 3 brings with it a wealth of improvements and interface refinements, based on feedback from thousands of students and educators from all over the world. User experience and flexibility have been a big focus for this release, as has been support for the latest hardware and a host of new, default applications.

At first glance, the thing that jumps out is the new dock along the bottom of the screen, which offers a familiar, icon-based experience that people have become accustomed to in the UIs of modern devices. The dock offers an immediate "something to do" and a familiar location to find and switch between running applications.

At the top right is a new Power & Settings menu, that offers quick, easier access to system settings and functions.

Other things experienced users will immediately notice are that the "Activities" menu has been changed to "Applications" (now that the actions that were there have been moved to the Power/Settings menu), an attractive dark theme throughout, and smoother, more fluid transitions when interacting with the interface.

The default application list has also been updated, with the latest and greatest versions of old favorites and many new ones. New additions include:

Clementine - A new music player with support for listening to internet radio from Spotify, Jamendo, Last.fm, Magnatune, SKY.fm, SomaFM, Icecast, Digitally Imported, Soundcloud and Google Drive and possibly Google Music in the future.
Gazebo - A well-designed robot simulator makes it possible to rapidly test algorithms, design robots, and perform regression testing using realistic scenarios.
Nitroshare - A cross-platform, peer-to-peer application designed to make transferring files from one device to another extremely simple.
TypeCatcher - Google Fonts provides web developers and designers with hundreds of open-source web fonts that can be used for free. This app makes it easy to download and install them.

Shotcut -  A free, open source, cross-platform video editor. Super fast, with a sleek, intuitive design. Supports HD, wide-formats, and a variety of device and transport options.

ArduinoIDE - The Arduino Integrated Development Environment connects to popular, inexpensive Arduino and Genuino open-source hardware to upload programs and communicate with them. Includes Hummingbird robotics support and Ardublock for younger students.

Atom - Atom is a text editor that's modern, approachable, yet hackable to the core. It's extremely flexible and customizable, with a built in package manager, smart autocompletion, and multi-pane views. Ideal for scripts and code.

Darktable - Open source photography workflow application and RAW developer. A virtual light table and darkroom for photographers. It manages your digital negatives in a database, lets you view them through a zoomable light table and enables you to develop raw images and enhance them.

LibreCAD - A fully comprehensive 2D CAD application. LibreCAD can read DXF and DWG files (and others). It writes DXF files, but can also export SVG, JPG, PNG, PDF and other files. It has layers, blocks, splines, polylines, ellipse tools, advanced tangent line & circle tools, transformation tools, an advanced snapping system and more.

Synfig Studio - 2D animation software, designed as powerful industrial-strength solution for creating film-quality animation using a vector and bitmap artwork. It eliminates the need to create animation frame-by frame, allowing you to produce 2D animation of a higher quality with fewer people and resources.

QT QR Code Generator - Software that let's you generate QR codes easily, scan an image file for QR codes and decode them or use your webcam to scan a printed one.

Geary - An email application that allows you to read and send email with a simple, modern interface. Supports Gmail (including labels and archive), Yahoo! Mail, Outlook.com, and popular IMAP servers (Dovecot, Cyrus, Zimbra, etc.)

Getting Things Gnome - Getting Things GNOME! (GTG) is a personal tasks and TODO-list items organizer, inspired by the Getting Things Done (GTD) methodology.

Features Definition of tasks and subtasks, resources and resource groups, dependencies between tasks, display of the critical path, calendars with working/non-working time, gantt chart and resource usage overview, HTML export of project plans, translated to over 50 languages.

BlueJ - An integrated, interactive Java development environment, featuring class structure diagrams, interactive invocation and an easy-to-use interface.

Python IDLE -IDLE (Integrated DeveLopment Environment or Integrated Development and Learning Environment) is an integrated development environment for Python, which has been bundled with the default implementation of the language.

PiTiVi - An intuitive and flexible video editor that integrates well with ubermix and can appeal to newbies and professionals alike. Pitivi has a beautiful and intuitive user interface, a clean codebase and a fantastic community.

Backups (Deja-dup) - A simple backup tool. Features support for local, remote, or cloud backup locations, such as Amazon S3 and Rackspace Cloud Files, securely encrypts and compresses your data, incrementally backs up, letting you restore from any particular backup, schedules regular backups.

There are a number of changes under the hood as well. Now that storage is less of an issue and devices typically include at least 32Gb of space, the default size of the user changes space has been increased to 8Gb and automatic update prompts have been turned on. What this means, however, is that system updates will begin to take up the user space as they are applied. While the default settings will be fine for most users, advanced installers should consider this when selecting a size for the user changes partition while doing an advanced install.

This release will carry ubermixers well into the future, with updates through May 2019. To download, click Download and Install above.

Latest Smarter Balanced Secure Browsers

Posted by Jim Klein On Friday, January 15, 2016 0 comments
For those of you in CA looking for the latest CAASPP Secure Browser version 8.1 for State testing in California, it available for easy installation from the ubermix repository. The repositories for both ubermix 1.x and ubermix 2.x are both up-to-date as of last fall.

The secure browser is used to administer the Smarter Balanced formative and summative assessments to all students in grades 3-8 and 11 throughout the State of California, and is quite a pain to install according to the "official" instructions, so having it as part of the ubermix ecosystem makes it significantly easier for schools and districts in CA to deploy.

Installation Instructions

The CAASPP Secure Browser and its dependencies are well over 50 megabytes, so if your school is starved for bandwidth, you may want to plan accordingly.

GUI Method:
  1. Click on Activities, then select Synaptic Package Manager under Administration.
  2. When the Synaptic Package Manager window appears, click on the Reload button to update the package list for all of the online software repositories.
  3. Once the reload is complete, use the Quick filter box to search for "secure-browser-ca" for standard ubermix 2.x or "secure-browser-ca-32" for 2.xL(ite) and 1.x. Once it appears on the list, click on the checkbox next to it and choose Mark for Installation.
  4. Click on the Apply button, and Synaptic will download and install everything you need.
  5. The CASecureBrowser icon should appear under Internet in the Activities menu. If it doesn't appear immediately, don't panic - it will after a restart.
Terminal Method:
  1. Press ctrl-alt-t to open a terminal
  2. Type  sudo apt-get update to update the package list for all of the online software repositories.
  3. Type sudo apt-get install secure-browser-ca on standard ubermix 2.x or sudo apt-get install secure-browser-ca-32 on ubermix 2.xL(ite) or 1.x to install the browser.
  4. The CASecureBrowser icon should appear under Internet in the Activities menu. If it doesn't appear immediately, don't panic - it will after a restart.

The antifragility of ubermix

Posted by Stephen Johnson On Saturday, September 19, 2015 0 comments
"Antifragility" was coined by Nassim Nicholas Taleb in his book Antifragile. To best explain the idea, we need to discuss fragility and robustness. 
Think of an egg. You drop it on the ground, and it looks like this: 

That’s fragility. Introduce a little force or instability, and destruction soon follows. Fragility should be avoided at all costs: fragile governments, fragile investments, fragile jobs… the list goes on.

What does fragility look like in education? Intervention just for the sake of intervention. Unsustainable 1:1 deployments. Rigid adherence to curriculum. Lack of training. Implementation of (big) ‘Systems’. Teachers isolated in classrooms. Spending money on programs, training, and technology that isn’t helpful. Unneeded hierarchy and bureaucracy. A narrow understanding of how to increase student learning.

Think of a bowling ball. You drop it on a tile kitchen floor, and it looks like this:

That’s robustness. Introduce a little force or instability, and the object, person, organization, isn’t affected. Obviously, this is more ideal than fragility; it’s where the bumper sticker "Tough times go away; tough people don’t" comes into play.
What does robustness look like in education? A program that can keep functioning with a lack of funds. Lesson plans that are effective year to year. A 1:1 deployment the district can maintain. A well-rounded understanding of how students learn. A district that is financially stable. Quick reaction to unforeseen events.


Do you remember Hydra? When you cut off one of its heads, two more sprout back in its place, like this:

That’s antifragility. Introduce a little force or instability, and the object, person, organization, etc. becomes stronger
What does antifragility look like in education? It’s a 1:1 deployment where the devices are used in new and interesting ways when the WiFi isn't working. It involves teachers who think quickly on their feet and provide engaging lesson plans, even in the midst of all the challenges schools face on a daily basis. It’s principals who implement amazing programs, activities, and training sessions on shoestring budgets. It’s districts who thrive in times of financial hardship. It’s students who enjoy fixing technology in their classrooms and view broken devices as exciting learning challenges. It’s a district or school who, like Hydra, becomes stronger, smarter, and more experienced during times when other districts and schools crumble.

Enter ubermix, which provides over 60 free applications pre-installed. This means students can continue working even if WiFi connectivity is lost. Ubermix allows for greater customization than Windows computers, Chromebooks, and iPads. There's no spyware or malware. Students and parents can download ubermix and use it on devices at home. It provides the ability to quickly recover from problems and restore the system to a default state. Updates are easy and not intrusive; in other words, students won't be forced to restart computers in the middle of a project because of an update. Oh yes--and ubermix is free. So there's no fee for licenses or management. All you need to pay for is the device. 

All school and district leaders want their organizations to be antifragile or robust. Choosing a fragile device and operating system for students is a surefire way to create frustration and negatively affect student learning. With the antifragile paradigm in mind, ubermix is a wise choice for every school and district. Even in the midst of instability--be it WiFi issues, lack of funds, or teachers who are inexperienced with technology--ubermix thrives.
