Sugar is a free and open source computer desktop environment designed for interactive learning by children. Copyright by SugarLabs.[1][3] Developed as part of the One Laptop per Child (OLPC) project, Sugar was the default interface on OLPC XO-1 laptop computers. The OLPC XO-1.5 and later provided the option of either the Gnome or Sugar interfaces.[4]

Sugar is available as a Live CD, as Live USB, a package installable through several Linux distributions[5]

Unlike most other desktop environments, Sugar does not use the "desktop", "folder" and "window" metaphors. Instead, Sugar's default full-screen activities require users to focus on only one program at a time. Sugar implements a journal which automatically saves the user's running program session and allows them to later use an interface to pull up their past works by date, activity used, or file type.

About[edit]

Sugar is an operating system which reinvents the use of computers for education in our society. Collaboration, reflection and discovery are incorporated straightforwardly into the user interface. Sugar encourages “studio thinking” and “reflective practice”. Through Sugar’s clarity of environment, young learners and educators have the choice to utilize PCs in all alone terms. Students can reshape, reinvent, and reapply both software and content into intense learning exercises. Sugar’s concentration on sharing, criticism, and investigation is grounded in the culture of free software.

Information is about nouns; learning is about verbs. The Sugar interface is the first serious endeavor to make a desktop environment that is based on both cognitive and social constructivism which is designed for children. Sugar is based on three basic principles:

1. Everybody is an instructor and a learner;

2. Humans by nature are social beings and;

3. Expressive by nature. These are the pillars of a user experience for learning.

Sugar also considers two more truisms:

1. One learns through doing. If you want to learn more and more, then for that You have to do more and more.

2. Love is far more significant than duty-you want people to participate in things that are authentic to them, things that they love.

The Sugar platform is characterized by three qualities: -

1. The presence of other individuals is always present in the Sugar interface; collaboration is a first-order experience: instructors and learners interact with each other, bolster each other, critique each other and share their thoughts with each other;

2. Sugar Maintains a “Journal” for each user so that his/her task is reflected on it;

3. Through its excellent design, Sugar is discoverable: it can suit a wide assortment of learners with various levels of aptitude. It is easy to approach and yet it doesn’t put an upper bound on personal expression; one can peel away layers and go deeper and deeper with no restrictions.

Design principles[edit]

Sugar has the objective of being suitable for even inexperienced users, but provides more advanced facilities for the more experienced. The project's stated goal is to "avoid bloated interfaces", and "limit the controls to those immediately relevant to the task at hand.".[6] Applications run full screen, double-clicking is not used, and menus show icons.

Sugar is written in Python,[1] an interpreted language, and can be modified by users with programming experience. Desktop environments used by many operating systems are written in compiled languages such as C.

Software components[edit]

Sugar has forked a couple of the GNOME Core Applications and written most from scratch. Most applications developed by the Sugar team are forks of existing GNOME applications and based on GTK+. Applications developed by Sugar are very pragmatic which offers number of opportunity to avail which enhances the skills and make them dexterous in their field.Sugar Activities include Turle Blocks 3D, Ruler, Recall and many more.

This is the example which provides different activities in Sugar.

Hundreds of learning activities for Sugar can be downloaded from the Sugar Activity Library. Additional activities are available from third parties, such as the Project Ceibal portal in Uruguay.

History[edit]

In May 2006 Sugar's developers described it as primarily a "tool for expression," and plans were in place to include multimedia and social networking features.[7]

Since May 2008 Sugar has been developed under the umbrella of Sugar Labs, a member project of the Software Freedom Conservancy.[3] Some contributors are employed by One Laptop per Child and other related organizations, others are volunteers, in many cases associated with the free software community.[8] Contributors to the original Sugar platform included Marco Pesenti Gritti, Walter Bender, Christopher Blizzard, Eben Eliason, Simon Schampijer, Christian Schmidt, Lisa Strausfeld, Takaaki Okada, Tomeu Vizoso, and Dan Williams.[9]

Cross-platform[edit]

By early 2007 Sugar could be installed, with some difficulty, on several Linux distributions, and in virtual machines on other operating systems.[10] By mid-2008 Sugar was available on the Debian, Ubuntu, and Fedora distributions of Linux; e.g., as of Ubuntu 8.04 (Hardy Heron), Sugar could be installed from the official Ubuntu universe repositories.[11] By mid-2009 Sugar was also available on openSUSE[12] and other Linux distributions.[10] Sugar 0.82.1 was included in the OLPC system software release 8.2.0 for XO-1 laptops.[13] Sugar 0.86 was released on September 30, 2009.[14] Sugar 0.88 was released on March 31, 2010.[15] Sugar 0.90.0 was released in October, 2010.[16] There were three releases in 2011 and one in June 2012, which included support for the ARM architecture on the XO 1.75. Builds for OLPC XO laptops and the release schedule are available at OS releases. Sugar has unofficially been ported to run on Android, Firefox OS and iOS using HTML5 and JavaScript under the project name "Sugarizer"; with additional clients written for Web browsers supporting HTML5.[17]

Sugar on a Stick[edit]

The Sugar learning platform for Linux is available as a USB-bootable Linux distribution ("Sugar on a Stick"[18]) and as software components forming an installable additional desktop environment for most Linux distributions.[3] It can be installed using the Fedora Live USB Creator, and can be installed onto a computer hard disk using the liveinst command from a Sugar Terminal or console.

On June 23, 2009, Sugar Labs announced the availability for download of Sugar on a Stick v1 Strawberry, which can run from a bootable 1GB USB flash drive.[3][19] On July 23, 2009, Recycle USB.com went live with a program to reflash used USB keys with the Sugar software and donate them to schools.[20] On December 8, 2009, Sugar Labs announced the availability of Sugar on a Stick v2 Blueberry, which incorporates Sugar Release 0.86 and Fedora 11.[21] Sugar Labs announced the availability of Sugar on a Stick v3 Mirabelle, which incorporates Sugar Release 0.88 and Fedora 13.[22] Since Mirabelle, Sugar on a Stick has been a regular, semi-annual, Fedora Spin (official special-purpose version of Fedora);[23] the a Spin using Fedora v22 was released on 26 May 2015.[24]

XO-1 Usage[edit]

The OLPC XO-1 has a 1 GB NAND flash drive and 256 MB of memory. Because the flash-based hard drive is small, swap can only be added by using an SD card or a network block device.[25]

If too many activities are loaded at the same time there may be performance problems due to low memory or processor load.[26]

Blueberry[edit]

Sugar on a Stick v2 Blueberry was released on 8 December 2009. It is based on F12 version of the Fedora operating system. It contains a number of features that improve the overall user and learning experience. Here is an overview of the most notable ones:

  • Sugar on a stick v2 Blueberry ships Sugar release, 0.86.3. Its features are:
    1. Redesigned toolbars
    2. Better Gnash support for Adobe flash content
    3. Improved wireless networking
    4. Support for tabbed browsing
    5. EPUB file support for e-books
    6. Easier keyboard configuration
    7. Easy way to update to the latest activities
  • ZyX-LiveInstaller:
  1. In high demand was a software to install Sugar to a hard disk. Hence Sugar teamed up the zyx-liveinstaller developer in order to provide:
    • Seamless installation of personalized environment into your computer’s hard disk;
    • It saves changes made to Sugar;
    • It does not require boot again and again.
  • Activities
  1. It includes updates to the standard collection of Activities for children and many new ones. An example is TamTam activity suite, which takes the user on a journey through Sound and Music.

Mirabelle[edit]

Mirabelle was the 3rd release of the Sugar on a Stick project. It was released on 25 May 2010.

  • Sugar version 0.88 features:
  1. Support for 3G connections
  2. Increased accessibility
  3. Better integration with activity portal
  • Sugar on a Stick is now a Fedora spin. After two prior releases of being based on Fedora Distribution, Sugar on a Stick has been recognized by Fedora Project as an official Spin. This ties us more closely to Fedora's release cycle and gives us resources from their engineering and marketing teams, which extends the reach of Sugar on a Stick and makes the project itself more sustainable. In exchange, users of Fedora have access to an easily deployable implementation of the Sugar Platform; it's a great example of a mutually beneficial upstream–downstream relationship.
  • Contributing to Sugar on a Stick – The biggest difference in v3 has been in its release processes and engineering sustainability;

Sugarizer[edit]

Sugarizer is a way to use Sugar on any device using web technologies (HTML5/JavaScript). Sugarizer is not a port of Sugar. It is based on Sugar web library, which resembles the Sugar User Interface using HTML5 and CSS3 and reproduces Sugar views. Sugarizer reimplements features of Sugar Core (datastore and journal) in JavaScript and integrates a bunch of activities written for Sugar in Sugar Web. So basically, Sugarizer is "just" a launcher of Sugar Web activities. A Sugarizer server component allows collaboration and presence.

Sugarizer could run any Sugar activities written in HTML5/JavaScript and include a bunch of Sugar activities written initially in Python and ported in HTML5/JavaScript (Physics, Paint, ...).

Sugarizer has a lots of features. Some of them include:

  • No installation required
  • Sugar Home View
  • Sugar Journal
  • Sugar Presence
  • Sugar Collaboration
  • Sugar Home view (Radial and List)
  • Runs any Sugar Web Activity from a Sugarizer Server
