I have recently come across a cloud hosting company that sets itself apart from others. OwnOcean.com utilizes an open source technology called ownCloud and offers stable and secure private cloud storage to the consumer. In fact, the stability and security, and speed of ownCloud server hosting service are points of pride with the people at OwnOcean.com. How they do this and what they can do for you is what I’d like to address here.
First of all, setup is fast and easy. Simply click on the green Sign Up button in the upper right corner. A window will open asking you to provide an email address and your desired password. It’s that easy. The OwnOcean team will send you an email message confirming your username and providing you with a link to your ownCloud server login page. They also provide you with a link to a blog that will provide you with step-by-step tips and an integration guide. Their tech support team is always available if you need them. Few things in life, and especially in technology, are this easy.
Now that your ownCloud server has been set up by OwnOcean.com, let’s talk about security. When you set up an account with OwnOcean, you’ll be provided with 15 gigabytes of storage space on your own personal server. Most cloud hosting sites will have multiple users on the same server. The real danger with this practice is that if one account is then compromised it’s possible that the other accounts could be compromised as well, whether the threat is a software bug, a hacker or malicious software. With OwnOcean, you own your own server.You have complete control over it and over your data. If you’re a professional and want to protect clients’ confidential information, the people at OwnOcean make it extremely easy, via one of their many integrated plugins, to encrypt your data. This means that in the event that an unauthorized individual does access your data, it will be indecipherable to them. Furthermore, OwnOcean employs layers of protection to secure your data and privacy. How’s that for security? OwnOcean boasts “rock solid stability”. Crashes on such stable systems are almost unheard of. This stability comes from the fact that ownCloud operating systems are able to identify potential threats to stability and neutralize them before they become problematic. What all of this means is that your cloud will always be available to you. With such stability and high levels of security, having a cloud with OwnOcean is very similar to having a virtual Web-based vault for your data.
One of my favorite features of ownCloud is the capacity to create users and groups. As the administrator of your ownCloud server, you can create accounts for others to use to access specific pieces of data. You simply create a user account and then assign groups to which the user will belong (by default admin is the only initial group) and to which group, if any, that they will have administrative privileges.You can also assign storage space to this user. Groups can be just as readily created. The real value here is that it makes project collaboration easy. First of all, you would create a group for the project. Then you would either add desired users to the group or create new users and add them to the group. Then upload the file you wish to share, or create it in ownCloud. Anything created in ownCloud can be shared. As this file is on a cloud drive, members of the group can make changes to it from anywhere at their own convenience, so long as they can access the Internet. OwnOcean will keep track of the changes made and who made them. In short, this means that you could literally have a project to which collaborators around the world could contribute. ownCloud offers many plugins (called Apps), some of which are already installed, to enhance its functionality out of the box. There are many pages of Apps available on ownCloud’s Web site, so you’re more than likely to find something to meet your needs. In short, your ownCloud server can become anything that you need it to be. To help you find the right plugin, ownCloud’s plugin page has an integrated search tool. In addition to this, users can rate Apps, so that you have others’ experiences and impressions to help you make a choice. The icing on the cake with ownCloud is its Web Interface, which is very approachable and intuitive. Everything can be managed through either the Navigation Bar on the left-hand side or through Search/Settings at the top of the Web Interface window. ownCloud also provides a desktop syncing application that can be downloaded for Microsoft Windows, Mac OSX and Linux, which makes syncing files on your computer with files on your cloud simple. All of these terrific features have made an ownCloud believer out of me. I know my data is secure. Is yours?

I have been asked to review and write a blog for a new open source Cloud hosting service. This service offers stability and security at the highest levels. It also offers a great deal of functionality and flexibility. I’m very excited about this opportunity and have been very impressed with what I’ve seen so far. When the blog is published, I’ll post it here. I’m also very excited to be a part of such a project. More to come.
If you haven’t heard of Scratch, then you’ve been missing out and so have your students. Scratch is an open source programming environment, with an integrated programming language also called Scratch, created by MIT with the goal of introducing users, especially young people, to computer programming. Users can create interactive stories, games and graphics. Furthermore, these creations can be shared with others via Scratch’s Web site. This is an excellent way to introduce your students to STEM.
What makes Scratch so special? To begin with, the interface is unlike that of any application of this type that I have seen. A menu bar/toolbar is provided for frequently used tasks, such as opening saved projects and sharing completed projects. From there, the interface goes in its own unique
One of the biggest differences between Scratch and other applications of this type is how the programs are written. Rather than typing code into a text editor, users are provided with a switchboard at the top of the leftmost pane. The buttons on the switchboard represent eight categories of commands that can be employed. The commands appear below the switchboard and can beadded simply by clicking on them and dragging them to the pane on the right. Here the commands can be connected in a fashion that combines a flowchart with puzzle pieces. Programs, called scripts, can be created for any object (sprite) that the user creates. These scripts integrate variables as well, such as waiting times for events or results of interaction with other objects.
Finally, one of the really cool things about Scratch is the integrated graphics system. This includes a versatile drawing tool as well as graphical images included with Scratch. The drawing tool runs in its own window and provides users with everything they need to create colorful, detailed sprites. These sprites can in turn be modified under the Costumes tab in the same pane into which programming commands are placed. Using this feature, animations can be easily created using two or more costumes for a sprite. Users can also create backgrounds or select backgrounds from Scratch’s media library. The author used just such a background for his outer space scene shown in the screenshot above.
I cannot even begin to do this application justice here. Check out the Scratch creations submitted to the Scratch Web site. Try it for yourself. Then introduce your students to Scratch and watch worlds unfold.

I’m currently working on an article about a brilliant piece of open source software called Scratch. It’s created and maintained by MIT and designed to teach beginning computer programming to young people, but gives them the opportnity to create interactive stories and games. These can then be shared with others online. I’m really excited about this fun and versatile application. The screenshot below provides a preview of Scratch.
Today I want to focus on the KDE Education Project or KDE-Edu. As you may know, KDE (K Desktop Environment) is an open source graphical interface for UNIX-based operating systems like Linux. KDE-Edu is a project started by the people at KDE with the intention of developing educational open source software for all ages, both learners and teachers.
The software that they produce addresses language arts, mathematics, science and social studies as well as other areas of learning, such as computer programming and occupational therapy. Language arts appplications range from KHangman, a variation of the popular word game to KWordQuiz, a vovabulary builder, to Parley, a powerful vocabulary assessment tool. Mathematics applications range from KBruch, a tool for quizzing users about fractions and facotrizations to applications addressing more advanced topics, such as KAlgebra for graphing algebraic expressions and Kig, an interactive geometry tool.
In terms of science software, KDE Edu has some interesting offerings. These include, but are not limited to, an interactive periodic table of the elements, Kalzium, a virtual planetarium for your computer desktop, KStars and Step, an application that allows users to create virtual two-dinmensional physical science experiments. If you’re looking for social studies applications, check out Marble, a virtual globe that allows users to view Earth from various perspectives including geographical, historical and climate or KGeography, an application that quizzes users on their geographical knowledge including locations, capitol cities and flags.
Other applications include KTurtle, a program teaching beginning computer programming, KTouch, a typing/keyboarding tutor and KLettres, a tool for teaching younger students how to write their letters.
I cannot do KDE-Edu justice in this short space. There are more applications available than I have discuessed here. I urge you to check them out. They’re open source, free and will soon (as of this writing) be available for Microsoft Windows.
Marble is an open source virtual globe for your computer. I’ve written about Marble before, but it’s been awhile so I thought I’d revisit this application and share some of the features that have been introduced. Marble offers a variety of ways in which to view the Earth, including, but not limited to a geoographical map, precipitation, a street map and satelite view. There are many other maps that are availiable as add-ons, including globes of the planets and moons, historical globes from a variety of eras, a hike and bike map, public transportation maps and several maps created by MapQuest. In addition to all of this, Marble can be readily customized via its menus. Marble is part of the KDE Education Project and runs on Linux, Microsoft Windows and Apple MacOS.
GIMP is a very powerful, feature-rich and versatile image creation and editing tool. Better still, it’s open source. Users can do everything from simple photo enhancement to creating lively, eye-catching graphics. Among the tools built into GIMP are a wide variety of brushes, special effects for customization and support for layers. Web masters can even use GIMP to create image maps. In short, GIMP has every feature you would expect to find in a modern image editing application.
If you’re looking for a full-featured spreadsheet application that is light on system resources, you should take a look at Gnumeric. Gnumeric is an open source electronic spreadsheet program that is free, fast, light and stable. Users will find all of the tools one would expect to find in a spreadsheet -a sum tool, statistical analysis, cell formatting and graph/chart generation and insertion. These are just a few of the useful tools available. So check out Gnumeric and find your next spreadsheet application.
It’s summertime again (at least in the northern hemisphere). You’ll no doubt be taking lots of photos to cpature some memories. If you want a cutting-edge application to edit your photos, you need look no further than GIMP (GNU Image Manipulation Program). GIMP is a powerful and versatile open source application for creating and editing images. GIMP is every bit as feature-rich as Adobe PhotoShop, but at none of the financial expense. So why pay big bucks to modify your summer photos, when a viable alternative is so readily available?
