From South Korea with love (for Moodle) - OKMindMap

OKmindmap (OKMM) is a South Korean web-based mindmap service. This service is touted by its developers as the world's first pure Scalar Vector Graphics-based, no-Flash-plugin-required web technology.
 It is Freemind compatible, is Web 2.0 feature-rich and the good news is that it can be integrated with Moodle.

It's developers/researchers are Professor Ho Won (Division of Electrical Electronic, and Information Engineering,Kongu National University, Cheonan, Chungnam), Jinhoon Jang, Kiwon Park and Myungsun Hahm (JinoTech, Dyryongdong, Yusungku, Daejunsi, Republic of Korea).

They have co-written a research paper entitled "Development of Universal Purpose e-Portfolio Mindmap
System on Open Platform". For those of you who are academically inclined, you can download it here. The paper's principal development tool is OKMM. More papers can be found here. Professor Ho's Moodle module page compilations are found here.


I. FEATURES

Here are some of OKMM's impressive features:

• uses pure Javascript technology - no need for Flash 
• cloud technology - can run on most web browsers without any plugin installation. 
• plays YouTube videos within a node itself (note: as of July 2011, only works with Google chrome and Apple Safari web browsers)
• fetch data from Delicious, Twitter, and Face book (Social Networking integration)
• can be used as a ePortfolio
• has been tested with up to 40 concurrent users who collaboratively built a mindmap
• can be Google Search enabled so that the user can do Web searches within the application while building the mindmap(!)
• export to Freemind, HTML, TWiki, PPT, SVG, PNG
• import from Freemind and bookmarks
• conversion from a mindmap to a structure chart (and vice-versa)
• MOODLE PLUGIN (MOD)! More on this later in this post.
• export to HTML code - hence a mindmap can be embeded in a Moodle webpage or label!
• best of all, it is FREE and UNLIMITED as far as I know. In contrast, a Web 2.0 mindmapping service like http://bubbl.us allows a limited number of mindmaps to be created for every free account.

Marginalia and Nanogong co-existing in your Moodle 1.9 forums - a match made in heaven

In this post, I will explain how YOU can fortify your  Moodle forum by getting  the non-standard mods Marginalia and Nangong to co-exist in harmony. As Hannah Montana would sing, "it's the best of both worlds!". At least on a Moodle 1.9 site.


Nanogong

The Nanogong voice recorder by Dr. David Rossiter and Gibson Lam of Department of Computer Science and Engineering, Hong Kong University of Science and Technology, is an excellent audio recorder for Moodle. As mentioned on the Nanogong website, "it provides a very simple and transparent voice support for Moodle".



Marginalia

Marginalia is, as Geof Glass, the author puts it, "is an open source Javascript web annotation system that allows users of web applications to highlight text and write margin notes."

Red text indicates grammar mistakes by the student. Green indicates the correct sentence or text.

How to use the humble comma delimited (CSV) file to display private coursework marks right on your Moodle coursepage

Today's post is about a crude but effective method to display confidential user coursework data on any Moodle 1.9.x course page. All you need is the Display Data mod (created by Serafim Panov) and an Excel spreadsheet saved as a CSV (comma delimited) file. You can even dispense with Excel and just use good old Notepad to create the CSV file!

Do you like to use Excel to store your students' coursework marks? Like this?

Would you like to feedback the detailed marks to your online-Moodle students, but are concerned about privacy issues?

If replied "yes!" to both questions, then boy oh boy, do I have a treat for you. It's a Moodle treat from 2007 and it's really very simple to use.

How I speeded up my Moodle site (two essential tips)

Preface
If you are a Moodle 2.x user (Moodle 2.4.1 is the latest as of now - January 2013) looking to speed up your Moodle production site, you might want to check out Cloudways.com's article entitled "Boosting Moodle Performance - Tips To Speed Up Your Moodle Install", Jonathan Moore's excellent "Why Your Moodle Site is Slow: Five Simple Settings",  Frederic Never's equally magnificent "Make your Moodle courses load faster without fiddling with the server" and Jonathan Moore's "Why your Moodle site is slow: five simple settings".

My article below is still useful, but dated since I was using Moodle 1.9.15 during the time of writing. Anyway, I suppose you reading this because you're desperate for ideas to speed up your slow  Moodle site, right? If that is the case, Random Net Surfer, then you've come to the right place!

This article was first posted on Moodle.org here on 15th January 2011. At the end of this post, you will know how to speed up your site with mod_deflate. You will also know how to enable PHP caching for your website by installing eaccelerator. Lastly you will know how to monitor your website's resources with munin graphs.

45 days ago, I started by journey of hosting my own Moodle site on a Web Host company. I started off with shared hosting, got turned off by the slow speeds, then upgraded to Virtual Private Server. The site just chugged along but my students complained that the site would load ever so slowly. Now, 1.5 months later, it's a different story.


I have spent countless hours and days, while others are asleep, surfing the Net feverishly for ways to optimize and to speed up my Moodle site. I've surfed to moodle.org, googled my way through, gingerly typed detailed Linux commands along the way. BTW, I love Linux now.

I've experienced hundreds of emails to and from my Web Host company, had a major server outage, times when my domain didn't load, recovered from a full harddisk due to automated & unmonitored backup files (I can't forget that one!), blank Moodle pages, loss of data, recovery and backups along the way. I survived. But TODAY, I think I've finally got it. Henry Higgens of "My Fair Lady" would say, "By George! I think (s)he's got it!!!". Anyway....here are two reasons why I am SO HAPPY TODAY.

Reason1: My Moodle site FINALLY runs with mod_deflate page compression.
So my moodle http requested pages are compressed before they are sent to the users' web browsers. Benefit: faster loading of pages, less waiting by users for their Moodle pages to load. http://moodle.org/mod/forum/discuss.php?d=165904
