Secure and Stable Private Cloud Service …and It’s Open Source

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.

ownocean.com,ownocean,owncloud,energize education,energize education through open source,open source cloud service

OwnOcean.com’s Main Page

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’ll be guided through the sign up process, which begins here.

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.com,ownocean,owncloud,energize education,energize educaton through open source,open source cloud service

Don’t worry. It’s secure and could well be one of the best investments you’ll ever make.

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.

ownocean.com,ownocean,owncloud,energize education,energize education through open source,open source cloud clients

The OwnOcean Team sets up your account

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.

ownocean.org,ownocean,ownloud,energize education,energize education through open source,open source cloud clients

Just log in to use your new ownCloud account.

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.

ownocean.com,ownocean,owncloud,energize education,energize education through open source,open source cloud services

Your new ownCloud account is ready!

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?

New Cloud Service Under Review

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.

gbrainy -Lumosity without the cost and hype

We’ve all seen the ads for Lumosity, the Web-based service that boasts games that “train your bran”. You also have to pay to use Lumosity, something the ads don’t tell you. Well, I want to introduce you to a free and open source application that does the same thing and touches on exactly the same areas that Lumosity claims to address, but without the cost and fanfare. The application is gbrainy and we’re going to examine its components so you can see how it can help you train your brain.

gbrainy’s main menu

First of all, you may wonder what are the components of gbrainy? gbrainy consists of four components: Logic puzzles which are designed to challenge your reasoning and thinking skills; Mental calculations, which measure your ability to mentally solve arithmetical calculations; Memory trainers are designed to test and improve your short-term memory; Verbal analogies assess your verbal aptitude.

A sample logic puzzle

Logic puzzles presents the user with a scenario and a question. Answers to questions can be both selected response and constructed response. The user can respond either by using the mouse, the keyboard or either one, depending upon the type of question. The puzzles measure users’ attention to detail as well as reasoning skills. So how do gbrainy’s Logic puzzles compare with Lumosity? Among the skills that Lumosity claims to promote are attention, speed of processing and flexibility. These games certainly help to cultivate these skills.

The author tries to solve a Mental calculation problem.

Mental calculations displays a mathematical equation to be solved by the user. The operations include common arithmetic operations, algebraic expressions, finding averages and working with decimals and fractions. The goal here is to determine the user’s ability to perform mental equations. gbrainy provides all of the data necessary to solve the problems. You need to provide the answers via keyboard or mouse. How does Mental calculations compare with Lumosty? They help to hone your speed of processing and problem-solving skills, just as Lumosity claims to do.

Improve your concentration and short-term memory with Memory trainers.

Memory trainers provides the user with objects to observe for a set period of time, then asks a question pertaining to what has been observed. These objects can be words, numbers or shapes and the amount of time to observe them is fixed. Input is given solely through the keyboard. For example,take a look at the Memory trainers screenshot to the right. After observing the numbers provided for the time allowed, gbrainy switched to a screen asking me how many odd numbers were listed on the previous screen. I actually found Memory trainers to be the most challenging of gbrainy’s puzzles due to the time factor. In comparison with Lumosity, Memory trainers matches it readily in terms of improving users’ short-term memory and their capacity to pay attention to details.

Verbal analogies: Do you think the author selection is correct?

Verbal analogies assess and improve your vocabulary. The puzzles are all selected response. The user may be asked to choose the best definition for the word given from a list. Alternatively, the user may be asked to select a word that will best complete a given analogy. Additionally, gbrainy provides alternate answers that would have also been acceptable in addition to the answer provided by the user. This is a great opportunity to build your repertoire of synonyms. In terms of Lunosity’s goals, Verbal analogies strengthens both your long-term memory and your processing speed. The Verbal analogies screen is shown at left.

In closing, I just want to add that I did not write this to condemn Lumosity. I wrote this article to simply inform people that a free alternative is available. For more information, visit gbrainy’s Web site. gbrainy can also be played on the Web here.

Scratch: The Launchpad for Students’ STEM Careers

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

direction, but still remains very user-friendly. In lieu of the traditional text editor/display pane layout, Scratch utilizes four panes, each with a specific purpose and interface. Operation and manipulation of objects is almost entirely point-and-click. This is arguably from where much of its ease-of-use comes.

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 be

The author’s Scratch session

added 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.

Energize Education Tip of the Day!

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.

Energize Education Tip of the Day- The KDE Education Project

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. ktouch,kde-edu,kde edu,kde education project

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.

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.
