Curate, Organize and Visualize Large Data Collections with TreeMap

Curate, Organize and Visualize Large Data Collections with TreeMap | Education Tech & Tools | Scoop.it

"TreeMap provides an easy, yet extremely powerful means of creating beautiful treemaps for analytical and presentation purpose. Importing data from a wide variety of file formats (including of course Excel), as well as connecting to databases (such as MySQL and SQL Server) is a breeze... and it scales to big data." from source: http://www.treemap.com/

If you are looking for additional visualization tools for displaying data, TreeMap v. 3.0 offers a classic tree map layout as well as others, like squarified variant, circular, tag cloud and voronoi.

Store, Share and Connect with Your Own Private Cloud: ownCloud | Education Tech & Tools | Scoop.it

"ownCloud helps enterprises concerned about sensitive data leakage via Dropbox deliver a secure file sync and share solution on site, on their storage, integrated with their infrastructure and security systems, managed to their policies. The result is an easy-to-use solution that provides complete control over sensitive corporate data." from source: https://owncloud.com

If you are looking for a good and safe alternative to Drobox or Box.net here is one: Owncloud is an open source software which you can install on your own web server and which provides you not only with full file storage and sharing capabilties, but also with the ability to connect directly to other file storage services and to run HTML5 apps.


Excerpted from the Techcrunch review: "OwnCloud is a free software suite, written in PHP, that provides file storage, synchronization, and sharing. It provides the same basic features of Dropbox or Box.net."


"The core ownCloud offering is file storage and synchronization. You also get optional contacts and calendar synchronization, if you want to use it. As an open source application, you can install it on any computer you control. This means you know how and where your data is stored, something which existing hosted solutions abstract away from you. Individuals and enterprises can install ownCloud on their own hardware, and define access policies according to their own needs."


"...the ownCloud mobile client can automatically upload pictures taken from your phone."


"...ownCloud can be connected to third-party storage like Dropbox or Google Drive or even an FTP server. These are read-write connections, allowing you to use third-party storage in whatever ways make sense for you..."


"...ownCloud supports HTML5 applications, allowing you to add all sorts of additional functionality. The ownCloud app catalog has dozens of apps."

Want your own private cloud drive?

ghbrett's curator insight, February 28, 2013 4:14 PM

This is a solution that makes a lot of sense to me. Keeping the curation and management of content locally will allow personal and enterprise installations to share content among their community. 

 

Be sure to read @RobinGoods' comments below that are much more detailed than mine.

Why Curation Will Transform Education and Learning: 10 Key Reasons

Why Curation Will Transform Education and Learning: 10 Key Reasons | Education Tech & Tools | Scoop.it
"This article, builds up over my recent presentation on Content Curation for Education that I delivered at Emerge2012 virtual conference.

In that presentation I claimed that the adoption of "curation approaches" will directly affect the way competences are taught, how textbooks are put together, how students are going to learn about a subject, and more than anything, the value that can be generated for "others" through a personal learning path.

If we learn not by memorizing facts, but by collaborating with others in the creation of a meaningful collection-explanations of specific topics/issues/events then, for the first time in history, we can enrich planetary knowledge each time we take on a new learning task." -- from source: http://www.masternewmedia.org/
ghbrett's insight:

As we produce more content and multimedia, who is going to clean up after us? Since we have endless storage on site and in many "clouds," there is less need to prune or delete data than ever before. This reviewer remembers having a disk with 26KB storage which needed to be used attentively. This article is one of the better of the emerging topic and related processes of Curating our stuff. Often the metaphor of one's Digital Footprints is raised as a way of describing all the different services, systems, machines, archives, etc., etc. that our stuff is. Oh, and then there are the other pack rats who have copied our stuff and put it into their stashes. Folks, it's time to take a moment to reflect on what we are doing with content, media, and stuff. Then curate by pruning, updating, aggregating, and other such digital stewardship. Finally, as my Father always said, "Don't do as I do, please do what I say." (grin)

Syrian Internet Connections Cut for Second Day

Syrian Internet Connections Cut for Second Day | Education Tech & Tools | Scoop.it
"BEIRUT, Lebanon — Activists in Syria reported on Friday that Internet connections were cut for a second successive day, fanning speculation among opponents of President Bashar al-Assad about the government’s intentions in coming days." from the source: http://www.nytimes.com/

 

NOTE: This is another example of recent national internet shutdowns. A reason I worry about Cloud Services like Google, SAAP, MOOCs, Amazons3, Apple iCloud, DropBox, etc., etc. Whether malicious intent, government intervention, or acts of technology or God.

Data Driven Journalism

Data Driven Journalism | Education Tech & Tools | Scoop.it

"This website is dedicated to providing anyone interested in getting started with data driven journalism with a collection of learning resources, including relevant events, tools, tutorials, interviews and case studies. The data journalism community and mailing list are dedicated to strengthening the community of journalists, designers, data providers and others, and encouraging collaboration and exchange of expertise.

 

 About our data driven journalism initiative

  The initiative is aimed at enabling more journalists to use data-sets as a source for reporting by providing them with the necessary skills, techniques and tools according to their level of expertise. In order to do so the EJC and its partners will:

  > Provide a series of hands on workshops across Europe and online training sessions with leading data journalists and open data experts to demonstrate how to find, analyse, and create new stories using data-sets.
  > Expand and strengthen an international network of data journalists, designers, developers, and others to encourage collaboration and to exchange knowledge of expertise and best practices with each other.
  > Create a collection of online resources - including interviews, case studies, and tutorials about how data can be used in the newsroom.

 

  If you are interested in partnering with us so as to help achieve these goals or if you have any other inquiries please contact the website editor Liliana Bounegru (bounegru@ejc.net).

 

  This initiative receives partial funding from the Dutch Ministry of Education, Culture and Science." -- from the Source

 

NOTE: This site is one of the first I have seen that is devoted to the interpretation and re-use of raw data in articles and reports. As we have more and more information produced as statistics, analytics, and raw data, it will become more important to be able to interpret and communicate the content in a meaningfull way for the audience(s).

The top 20 data visualisation tools | Feature | .net magazine

The top 20 data visualisation tools | Feature | .net magazine | Education Tech & Tools | Scoop.it

c/o Brian Suda: 

"One of the most common questions I get asked is how to get started with data visualisations. Beyond following blogs, you need to practise – and to practise, you need to understand the tools available. In this article, I want to introduce you to 20 different tools for creating visualisations: from simple charts to complex graphs, maps and infographics. Almost everything here is available for free, and some you have probably installed already"
from source: http://www.netmagazine.com/

ghbrett's insight:

This is a great article does indeed go from viz tools that are more simple to much more complex tools and data manipulation. They are all worth having a look see. This is especially true with the increase of people producing InfoGraphics that most always include charts or some sort of data visualization.

Interview with Francois Ferracci – the director of Lost Memories : One Small Window

Interview with Francois Ferracci – the director of Lost Memories : One Small Window | Education Tech & Tools | Scoop.it

"Lost Memories" c/o vimeo:  http://vimeo.com/49425975

 

"With a running time of less than three minutes the film Lost Memories makes a powerful comment on digital versus analog living as well as the nature of memories—especially when they are all tweeted, blogged or committed to a digital archive somewhere." - from the source

 

NOTE: This should be mandatory reading and viewing for Digital Literacy and for any Digital Media event or course. How fragile is our digital trail of files, images, musice, etc., etc.?

 

Often I wonder what might happen the the terabyte or so of digital images I have as well as the 10+ years of family genealogy (6 Gb) now on 2 hard disks (one as backup). Then I shrug my shoulders thinking it's too much. I do not have a good answer, but I note a revival among some photographers of analog film fotos. I note that genealogy books recommend acid free paper copies and prints of your historical and anecdotal information.

 

What are your thoughts?
