<h2>Abstract</h2>
Blogs are an excellent educational tool as demonstrated by the use of Google Blogger in [http://www.blogger.com/profile/06134894806578234196 Villa Cardal, Uruguay]. The kids using blogs had some issues and requested changes to make the system easier to use. Also, setting up the system on the XO was the difficult due to Blogger's many features and bandwidth intensive resources. Very few (if any) current blogging systems are developed for the purpose of education and easy enough for use by young children in the low bandwidth environment they have in third world countries. The Educational Blogger Project will address this problems. Essentially, it stores posts locally using Moodle or similar service and allows for kids to collaborate, gives teachers the control they need and will be optimized for the XO and low bandwidth. The Educational Blogger Project significantly facilitates the use of blogs on the XO environment and makes it available for more widespread use by allowing teachers and students to create and share content easily and efficiently on the XO laptop. The ultimate goal is to create an system that can be set up easily on any XS and used by kids around the world.

Blogs are an excellent educational tool as demonstrated by the use of Google Blogger in [http://olpc-ceibal.blogspot.com/2007/09/get-photos.html Villa Cardal, Uruguay]. The kids had some issues and requested changes to make the system easier to use. Setting up the system on the XO was difficult due to Blogger's many features and bandwidth intensive resources. Technicians needed to assist in actually posting the blog entries to the internet. Very few (if any) current blogging systems are easy enough for use by young children in the low bandwidth environment they have in third world countries. The Educational Blogger Project will address these problems. Essentially, it stores posts locally using Moodle (or similar service) and allows for kids to collaborate, gives teachers the control they need and optimizes the process for the XO environment. It also allows teachers to release posts to Google Blogger, WordPress or other blogging system. The Educational Blogger Project significantly facilitates the use of blogs on the XO environment and makes it available for more widespread use. The ultimate goal is to create an system that can be set up easily on any XS and used by kids around the world.

The design of this project addresses the concerns in the [http://wiki.laptop.org/go/Requerimientos_Para_XO requirements specifications]. The basic issues making it difficult to use current systems are the need for good connectivity, children getting confused with some options, the number of steps involved in creating a post, difficulty in collaborating on a post and difficulty with monitoring and viewing posts before being published.
The design of this project addresses the concerns in the [[Blogs Knight Challenge|requirements specifications]] (Please note there will be mismatch since many areas were changed during discussion with my mentor, but not updated on the requirements page).

;<b>EduBlog Client</b>
:This is a modification/plug-in to the Write Activity and serves as the interface between Write and the EduBlog server. This consists of a slight GUI modification to Write so that a "Publish" option is shown in the menu. Clicking on that option will bring up a GUI allowing the child to select what class the post is for. Finally, the child can click "Submit" and send the data to the EduBlog Server using HTTP. All accessory files, such as images, will be sent to the server as well. XHTML generation is done by the Write Activity (already supported). Also, clicking on edit in the Browse Activity will open up Write and preload the page for editing and allow for easy updating through the EduBlog Client. The client is also partly responsible for authentication; initial implementation will store a password in the XO and submit that securely (md5) to the server with the post.
;<b>EduBlog WebClient</b>
:This is a browser based editor that can serve the same functionality as EduBlog Client. This can be a stripped down version of the WordPress client interface.
;<b>EduBlog Server</b>
:The EduBlog Server handles most of the communication between subsystems. When a post is or edited, the EduBlog server will alter Moodle (with blog plug-in) tables appropriately (either directly or through the Moodle API). It will also deal with concurrent editing issues by locking the post or merging changes. The EduBlog server also augments the Moodle database to support the specific user types needed and handles a post's view and edit permissions. It also allows teachers to make certain posts public by publishing them to blog sites on the internet. This will be done with plug-ins that allow it to interface with various blog systems such as Google Blogger and WordPress using XML-RPC (supported by both Blogger and WordPress as well as popular blog exchange API's such as GData, MetaWeblog and MovableType). In addition, EduBlog Servers running on different XS's will replicate posts as necessary through daemon processes to optimize local and national bandwidth.
;<b>EduBlog Admin</b>
:This is a web interface to administer the EduBlog Server (through PHP and XHTML forms). Teachers can use this interface to view and control the posts made by kids in their class, create/delete users, edit posts made by their class, create groups that can collaborate on a post and release posts to the internet. Admins can use this interface to configure the system such as settings for releasing to blog sites on the internet and what data is to be exchanged with partner servers.

<h3>Beta Server Hardware and Software Details</h3>

Tarun has a basic FTP host with Apache and PHP which we can use for
mocking up the GUI. and doing some developing. Greg really wants to have a
full blown School Server just like they have in schools in Uruguay.

We need
# A box and someone to image it with XS code (Tony)
# A primary sys admin and support for them (Marcel)
# An IP address, BW and a hosting location (Glen)

Must haves:
* Ethernet configured for connection to Internet
** Accessible from XO laptops in Uruguay via HTTP
** Remote administration through SSH/FTP
* XS Software stack with web server, database, and utilities
* Recover CDs or DVDs

Nice to haves:
* Alternative OS such as Debian 4.0-r3 Etch with Dual-boot option and Grub loader
* Alternative databases (MySQL versus PostgreSQL)
* Logical Volume Manager (LVM2)
* RAID-1 configuration between the two SATA disks
* Backup through Mondo Rescue, SysRescueCD, Partimage, or similar
* KVM virtualization that would allow other images to run as Linux guests
* Ability to hot-add USB keys or USB external drives
* Install "git" source code revision management software (yum install git-core)

<h4>Hardware Requirements:</h4>

The requirements are loosely based on [[ XS_Server_Specification#XSX_Specifications ]]:

* 1.6 - 1.8 GHz AMD processor
* 2 GB RAM
* 160 GB disk (two drives, in RAID 1)
* three NICs (one WAN, and two LAN) the intent was to have a WiFi network inside the school and another for outside the school, but they are currently only using a single WiFi network.
* Six USB slots
* CD-RW/DVD-RAM for backup

Actual hardware implemented:
[[ User:Az990tony/edublog-beta-hw | EduBlog Beta Server Hardware ]]

<h4>Software Requirements:</h4>
* XS-160 or higher software build (based on Fedora 7)
* Apache 2
* PHP 5
* PostgreSQL 8
* Moodle
* FTP
* SSH

Actual software implemented:
[[ User:Az990tony/edublog-beta-sw | EduBlog Beta Server Software ]]

<h4>Backup / Recovery Method:</h4>

Tony has successfully backed up using "partimage" from the
[[http://www.sysresccd.org/Main_Page SystemRescueCD 1.0.3 ]]. In
this test, the system was booted from CD, partimage was run interactively
and the image files were written in 690M pieces to another disk partition.
Then, using
[[http://www.sysresccd.org/Sysresccd-manual-en_How_to_burn_a_DVD_with_SystemRescue_and_4_GB_more_files growisofs procedure ]] was able to create a bootable DVD that contained this backup copies.
It is not fully automated as Mondo Rescue, but close enough to move forward.

Tony has not been able to get "Mondo Rescue" to complete successfully (See
[[ XS_Backup_and_Disaster_Recovery ]] for details). More investigation is required.

<h2>About Me</h2>
[[Category:Educational Blogger Project]]
<p>
I am a 19 year old self taught programmer. When I was in 6th grade I began to teach myself programming by reversing engineering the code generated from Excel Macros, and then went on to learn Java and other languages. In 10th grade, I wrote an editor for Intel Hex that is now installed on all the computers in my high school and has been downloaded by over 2000 users. In late high school I started distributing my older software online (http://www.betarun.com) (still working on making the newer pages). I'm currently interested in web applications, graphical compilers and scientific graphics.
</p>
<p>
I realize now that my interest in programming has been a huge motivation for me to learn math and science so I feel that if children are introduced to programming at a young age they will also be instilled with a passion to learn. My ultimate goal is to create a powerful, yet simple, graphical programming tool that would allow people to create software with no code at all in an intuitive way that closely models the way we think that anyone can use.

Abstract

Blogs are an excellent educational tool as demonstrated by the use of Google Blogger in Villa Cardal, Uruguay. The kids had some issues and requested changes to make the system easier to use. Setting up the system on the XO was difficult due to Blogger's many features and bandwidth intensive resources. Technicians needed to assist in actually posting the blog entries to the internet. Very few (if any) current blogging systems are easy enough for use by young children in the low bandwidth environment they have in third world countries. The Educational Blogger Project will address these problems. Essentially, it stores posts locally using Moodle (or similar service) and allows for kids to collaborate, gives teachers the control they need and optimizes the process for the XO environment. It also allows teachers to release posts to Google Blogger, WordPress or other blogging system. The Educational Blogger Project significantly facilitates the use of blogs on the XO environment and makes it available for more widespread use. The ultimate goal is to create an system that can be set up easily on any XS and used by kids around the world.

Benefits of Educational Blogging System

  • Allows teachers to use blogging as an effective educational tool by adding teamwork capabilities, creating a collaborative environment for students and simplifying the process
  • Optimized for the XO and bandwidth, so users will have a great experience
  • Gives OLPC a source of feedback and a way to see what is important to kids
  • Makes kids happy! Kids requested blogging!

Problems with Current Blogging Systems

  • The need for good connectivity
  • Children getting confused with some options
  • The number of steps involved in creating a post
  • Difficulty in collaborating on a post
  • Difficulty with monitoring and viewing posts before being published

Details (Revised See EduBlog Implementation)

The design of this project addresses the concerns in the requirements specifications (Please note there will be mismatch since many areas were changed during discussion with my mentor, but not updated on the requirements page).

Use Case / Workflow

Tarun2000 workflow.png Original

1) Kid Creates Post
Children can use the Write Activity (AbiWord based) to create a post. A slight modification/plug-in to the Write activity would display a "post to blog" option for the child. When clicked, the post (taking advantage of Write's XHTML generation) and meta information (class its for, group, etc.) will be sent to the Educational Blogger Web Application on the XS. The XS will store the post locally using Moodle, WordPress or other similar web application (modified to incorporate needed user permissions, bandwidth optimized).
2) Kids Collaborate
Children in the same group can collaborate on a post. To edit a post, a child can click on an edit link (which will appear if they have permission to edit that post) in the browser. The link will open Write and load the file for editing (file extension association). Uploading the edited post will be similar to creating a post, except that the user will not be prompted for extra information when saving.
3) Teacher Controls Post
At all times, the teacher can view posts of all students in the class and edit/delete them. The teacher can also create users/groups, give students editing rights and perform other everyday administration tasks. The teacher also sets access rights for the post (internet, local, class only, group only).
4) Post Released
The teacher also has the power to release the post (publish Generic WordPress server or other blogging site). This would essentially transfer all the post data using XML-RPC. The post will also be available for replication on partner servers.
5) Post Exchange
A daemons system will replicate posts across partner servers. For example, a regional server could store all the posts in the region. Post Exchange serves to optimize a country's bandwidth as well as a school's bandwidth.


More detailed use cases with screenshots have been posted for the first beta test.
