AbiWord Online Collaborative Documents

Abiword, a lightweight open source word processor is now capable of online collaboration. In the previous post we were discussing how it would be nice if Google Docs had a client, and this may be that solution, but approached from the other direction.

I’ve created a collaborative document (tagged as ETEC522) which should be available to anyone who creates an account on AbiCollab, if you want to try it out.

Improving the Ratio

First off, thank you Module 7 for this presentation, it’s got me thinking in some new directions.

I was thinking through some of the issues with moving towards a 1:1 ratio, many of which are being discussed in the forums and comments, and looking for inexpensive ways of deploying more computers for students to use. I have better than a 1:1 ratio in my class, but my school at large is nowhere near. Here are two technologies that I’ve found, and I’m hoping that together we can find more.

Linux Terminal Server Project (http://www.ltsp.org/)

Linux Terminal Server Project (LTSP) is designed to connect multiple low-cost terminals to a powerful server which does all of the processing and storage for all users. The terminals can be old computers or newer thin clients, as long as they have a basic processor, video card, network card, and keyboard and mouse support. They don’t need any drives, as storage is handled by the server. Input by users is sent over the network, the server does the processing, and the results are resent over the network for the terminal to display. Practically, it’s like having your own machine.

The advantage to this is in costs and maintenance. The server is the only machine that needs to be setup and maintained. All of the terminals are interchangeable, and with the drives removed, the most common failures are gone as well. A single quad-core machine acting as a server (about $700) should run about 30 clients at reasonable speed. If the terminals are powerful enough, some processing can be done on them to reduce the load on the server too. Just about any old computer can be a terminal, so the clients can be old inventory or donated machines. Ubuntu includes a LTSP configuration in the install disk, so setting up a basic lab can be done in just a few hours.

The issue with this setup is that it uses Linux. While the OS and applications are free, it may be difficult getting IT to manage the system. If the IT already supports Linux, it should be an easy implementation.

Userful (http://www2.userful.com/)

From what I can tell, Userful behaves similarly to an LTSP environment, but instead of dummy boxes connected by network to the server, a keyboard, mouse, and monitor is connected directly  to the server. It also uses Linux as the OS, so the same implications with software as the LTSP apply.

There are some performance advantages to this setup. Since each monitor/desktop has direct access to a video card, video performance is improved. Also, since a server is limited to about 10 user desktops, each user could have a larger slice of the processing power.  The company claims that it costs about $70 per user in hardware costs in addition to the server. Here’s my own cost estimate for a brand new lab of 30 machines. You would need 30 modules ($2100), 3 servers ($2100), 15 video cards ($900), 30 keyboards, mice, and monitors ($6000), which comes to $11100. I imagine that many schools would be able to scrounge the keyboards, mice and monitors, and that would reduce the cost significantly, to just over $5000.

If you know of other options, I’d love to see more solutions for schools looking to expand their computer offerings.

OSS in Indonesia

Sorry for my delayed post, I was in Bali, Indonesia for the last week and although I brought my laptop, I had very few opportunities for internet access, connecting (and a slow connection at that) when I was in the main city of Kuta.

First of all, great work Group 6! I really enjoyed learning about OSS. Since I was in Indonesia, I decided to focus on this country’s use of OSS.

 OSS is starting to becoming popular in Indonesia with more Indonesian people using this free software. The government is looking towards the development of OSS as a way to reduce the billions of dollars being spent on software from foreign vendors and as a major prevention against piracy. The biggest difficulties are that Internet access is limited (only the big cities, some universities don’t have internet), the high cost of computers and the language used in the software.

 The Open Source Contributors Group (OSCG) was founded is maintained by people at the Informatics Engineering Department, Institut Teknologi Bandung, Indonesia http://www.itb.ac.id/en/. Anyone can contribute in this open source software development and technology enhancement group by contributing his/her works, ideas, opinions, and/or suggestions.

 The following are some of the institutes’ students early projects: (see this report for more information)  

gx-admin

This is a generic web-based interface for UNIX system administration using any browser that supports tables and forms. gx-admin was designed to be generic and able to configure any kinds of UNIX text-based system files. The configuration for this application itself is on a text file that enables users to add as many configurations as possible. gx-admin consists of a simple web server and a number of CGI programs which directly update system files. The web server and all CGI programs are written in Perl version 5, and only use the standard perl modules.

Pegasus

An indexing web robot that can be used to index some defined urls, a range of IP addresses, or even the whole web. Pegasus can be executed with a web browser (for an interactive interface) or straightly from the shell with valid arguments. It will send a request for a HTML page, parse the HTML page, save some significant information and then follow all the links in that page and repeat the process ‘recursively’. Pegasus will store the information on a database with PostgreSQL as its Database Management System. The database can be used for various purposes, such as search engine’s database for a website, or a private database which can be used to search information offline. Pegasus was written in Perl version 5.

 RTSimula

This is a suite of programs that simulate the behavior of railroad hardware model. The simulator is truly real-time and intended to be used for the course of Real-time Programming. RTSimula currently consists of three different programs: the simulator – runs on Real-time Linux – doing the simulation by calculating some parameters provided by users, a monitor – runs on X-Window – drawing crude visualization of the trains and railways, and a simple controller program. The whole suite of programs (and the documentations) were written using OSS: Linux, Real-time Linux, and GTK+. All programs were written using C language.

 Unicorn

This is a subject guide that has a search engine for its main facility. The search engine was developed to search information on a database as a result from Pegasus’ indexing process. Unicorn uses various techniques to search through the database, such as simple search, exact phrase search, and a wildcard search. Users can also define the options for the search process, including the search sequence and a time range of the last-modified date from a page in the database. Unicorn was written in Perl version 5.

 

Finally, here is a short video (not in english) that is used to campaign for Indonesia to go open source.  YouTube Preview Image

OSS Reflections from Egypt :)

Group 6, congratulations for the great work. Content was very much informative and engaging.

In this post, I’ll briefly try to reflect to one or more of the blog discussion topics you raised. From my own experience working for commercial IT companies, the OSS do exists in Egypt but with lower market share if compared to commercial software. There could be many reasons but the most obvious is the political power that international/global IT companies have established so far. For Example, company like IBM has established a research and commercial branch in Egypt since 1954, with this very early presence you can expect the type of relations IBM has with local government. Companies like Microsoft and Oracle had also established very strong connection with the government here. The driver for this type of partnership is a Win-Win situation, where commercial companies would offer very special prices and discounts as part of national-wide agreements, I recall few years ago there was an offer for college students to have Microsoft Office for less than $10. Of course with the economy of scale and future expansion would make such a deal justifiable. Initiatives to train K-12 teachers for almost zero cost encourages the ministry of education here to participate in Intel Future Teacher program, which mainly adopt the WinTel (Windows running over Intel processor) setup.

Another point I like to reflect on, is Moodle as open source. As M6 content showed, there are many ways to compare OSS with Commercial in terms of maintenance. Where I work now, we do offer Moodle services for our customers (Universities in the Middle East region). I’m always very careful when I promote Moodle to any prospect and make sure to set the right expectation. Many would be deceived that because it’s OSS there would be no hidden costs. On the contrary, you have to be prepared to host Moodle as if it’s a commercial software. You either need to have your own pool of resources who are very much capable of supporting Moodle and able to integrate it with other campus applications (like the Student Information System), or you should have a commercial agreement for support and maintenance with commercial company. That’s why beside Moodle.org , there’s Moodle.COM (the commercial arm of Moodle). But Moodle as OSS saves the customer the up front investment of purchasing users license, an excellent option to redirect part of the technology budget to other resources (hardware or other commercial applications). Nevertheless, I’ve ran into customers who don’t want to hear the word OSS !!, they want commercial and commercial only solutions, simply they want to deal with “real” single owner (a mortar and brick company) rather than virtual multiple owners – that is in thousands or even in millions -.

Still the OSS is attracting many developers here in Egypt and this is only one example http://www.eglug.org/  it’s the GNU Linux chapter in Egypt. Also I know of many other small companies who built their solution on top of OSS, biggest example I can think of web portals and content management solutions on top of Drupal and Joomla.

Learning OSS vs PS Software in Schools

After taking a quick look at open office.org it seems to me that there are many similarities with Microsoft office.  Now, I believe in students learning how to use computer technologies in schools.  Most businesses require employees to use their software for communication and development of presentations.  If I owned a business I would not be interested in training workers on how to use a simple word processor.  I would expect that they would have been exposed to that during their education, especially in these times which we are relying more and more on technology in the working world.  

Having said that why is it that students need to use Microsoft Word?  After quickly looking at open office it seems to me that the interface is very similar to Word.  Why is it necessary to have students or schools pay for expensive proprietary products when they can just use the free OSS offered on the internet?  Open Office also states that their program is fully compatible with most other types of software so there shouldn’t be a problem transferring documents to Open Office from other programs.   There are most likely subtle differences between Open Office and Microsoft Word as well and between other applications from Open Office and the Microsoft suite.  In my opinion it is probably not going to be so great that it would cause a new hire to undergo intense training in Word in order to be able to use its basic functions. 

Besides this brings to mind a couple of years ago when I was working as a teacher and the entire school upgraded to the new Microsoft Office 2007 product.  The differences between the older version and the newer version were huge.  Myself as well as many co-workers were very distraught with the fact that our work production was slowed because we had to learn how to use a new program.  Things as simple as finding the line spacing format tab and the print preview button became frustrating examples of changes to the program that slowed us down as workers.  Not to mention there were problems with viewing older works from other word processors that made reading some students work impossible, I’m not even going to get into the frustrations with Power Point!  So even with new versions of PS coming out every few years workers are going to have to undergo some changes to what they are used to using anyway.  If employees are going to have to make changes anyway why not just encourage schools to use the free software for their students so they can cut down on their costs?  Better yet why don’t we have businesses using OSS technology and saving themselves money?

Open-Source as a Classroom Alternative

Blog Question: Would you support implementing FOSS/OSS in your work environment?

As a secondary teacher I support the use of FOSS and OSS in schools.  I think they are a cost-effective and useful way to bring great software to students.  Not only does most of the software “just work” it is often frequently updated based on user comments and could even provide an opportunity for students to help out with the software.

Although OSS software may not always be the best option, I still prefer Word and Powerpoint for instance, but they often they can bring software to the classroom that might not otherwise be there.  For instance open-source CAD software (Cademia and avoCADo, video editing software (Virtual Dub and ZW-4) or audio-editing software (Audacity).

To give an example of OSS in the classroom I thought I would share an experience I had with OSS in my classroom.   A few years ago I was asked by my principal at the time to develop a new computers/information processing class for the grade 9’s.  After weighing out the various options and considering that I had zero budget I decided to develop an image and photo editing class built around the amazing FOSS photo editor Paint.net.  The software is nearly as  advanced as high-end, and extremely expensive, editors like Photoshop and also has a similar interface and shortcuts.  This is great for students who might pursue photo editing further and makes the transfer of skills easy.  The software also had numerous online tutorials, guides and help pages that were easy to use and navigate.   All of this made it extremely easy to develop a course around the software and give my students some valuable technical skills.

In the end the class was a huge success and I they are still using my materials and Paint.net to teach the class.  Although Paint.net has undergone over 2 years of revisions most have been additions, not major changes and most of the material required little or no change to support the new software.

Anyways, it is this and other positive experiences with OSS that have led me to use it more personally and professionally and I encourage other people to think twice about buying new software before exploring what OSS has to offer.  A handy site is Open-Source as Alternatives which lists alternatives for many types of software we normally pay for.  The site allows you to list commercial and alternative software by OS and by use.

Students Learning OSS vs PS

Module 6 Blog Question: There is an argument that students should use proprietary software (like Microsoft Office) in schools as they will most likley have to use it in the work environment. Opponents of OSS in schools feel that using applications like OpenOffice.org to teach students office productivity applications would put them at a disadvantage in the workplace. Do you feel that the skills students would learn on OSS applications can transfer to proprietary applications? Take a look at OpenOffice.org, or other applications that could be used in schoools, and then post your ideas to the course blog.

 I’m not sure that it would put them at a disadvantage. Skills learned using OSS applications such as OpenOffice can be transferable should the student get a job in an organization using Microsoft Office. For example, in OpenOffice Writer, there is a toolbar with similar functions to MS Word and drop down menus. What I think is more critical is that in school the student learn to write effectively (grammar, sentence structure, expression of an opinion/thought, analytical writing). The application used to write with would be a secondary concern, with the thought that if you can use OpenOffice Writer than you possess computer skills and that the individual would likely be able to make the transition/leap to MS Word with a bit of assistance from the Help Function or tutorial.

FOSS/OSS in Public Schools

Blog Question: Would you support implementing FOSS/OSS in your work environment?

At my small secondary school, we already support FOSS/OSS use.  Our server is run with Apache software and is hosting Moodle for some of our classes.

On another note, the Vancouver Board of Education has now installed OSS software such as Open Office and Gimp onto board-issued computers.  I know there are some teachers, including myself, that aren’t too keen on the Open Office at this point because most of our computer files are MS Word-based.  Even though Word files can be opened with Open Office, often, some of the formatting is lost.  I think it will definitely take some time before people get used to it and start transferring files over to using these OSS software programs.  It sort of reminds me of way back in the day when there was the battle of web browsers…Netscape vs. IE.  I can’t remember how many times (lots!) that I switched between the two browsers as my default.  One would come up with new features and I would then switch to that one.  This went on for years until, of course, IE won out.  Now, I’m using Firefox. =)

In general, I would support FOSS/OSS in public schools; however, only if we were given more tech-support from our school board.  Last thing I want is to become the tech-support guy every time one of my colleagues has a problem with the OSS.  If that’s the model (i.e. teachers becoming their own tech-support) that the school boards are going to then I would not support it.

OSS in Schools

I would be all for adding OSS to my work environment. Working in a high school the possibilities of many of these free software programs are endless.  Take a program like Odijoo which allows you to create publish and store online courses.  Teachers could augment the courses they teach with online modules….. something like a webquest?  It would cost the school nothing and would develop a whole new world for students to learn in.  Students could log on from any computer connected to the internet at any time.  It would be a great way to fit in that unit that there just isn’t time for.  It could  be an interactive independent study opportunity, all for no cost.

Thoughts on creating M6 with OSS.

I thought that I would share some of my experiences using open source software (OSS) to create this presentation. I’m not an OSS guru, although I’ve been using it much more since last term when I created a project about the implications of using it in education. This presentation was a chance to look a little deeper at some of the other aspects.

There are many free solutions for hosting a website. Ning, for instance, helped the previous two groups create great presentations, complete with comments, RSS feeds, e-mail notifications, and common logins. Google Sites is another option. It also includes the ability for all group members to contribute. We settled on Joomla because I knew it was open source, I had used it once before, and I have access to a Web server and necessary databases to install it on. Another option for us, would have been to use WordPress like the blog used in this course.

I won’t lie, there were a lot of frustrations with using Joomla. I can let my group members speak for themselves, but even up to Sunday night, there were lots of little things going wrong. For instance, if you embed a YouTube video, then edit the page after, the video is gone. I’ve since learned that using a different editor would have avoided that problem. Nevertheless, there were a lot of little issues, and under a deadline is not the best time to find them. Several people have already commented about this, and having a little more time to experiment before diving in would’ve been nice.

There were a lot of things that went well. First of all, it seemed really fitting to present this module on an open-source platform.  When we had decided upon the basic layout of the presentation, it was easy to add, remove, edit, and hide pages as needed. It was relatively easy to implement additional functions like the comments and forums, and there were a multitude of options for each choice. There were close to 10 comment systems to choose from. As it turns out, Joomla is designed to be able to handle huge and complex websites with multitudes of authors, including both backend administrative authors and front-end users. It has a lot of features in common with WordPress, likely because of their open source heritage.

I also used OpenOfficeSeaMonkey, and Gimp to create/edit content. All three of these applications work perfectly for me. There was no experimentation, I found no glitches, and they worked exactly as advertised. I would’ve been satisfied paying customer. All three of these should be beacons in the OSS community.

The big question, was it worth it? I think it was. Although Joomla is designed for more that we used, and I would like to try other content management systems too, it did the job well, giving us a clean layout, easy organization, and the ability for everyone to contribute. Like I said before, there are lots of free solutions, but I don’t regret giving OSS a chance.
