AICTE Locks In Indian Colleges

“Microsoft provided enterprise-grade services and support whereas other vendors did not,” says Dr. SS Mantha, Chairman of AICTE. “Data security and privacy were of paramount importance to us, and we felt that Office 365 offered the compliance features that we required.”

Enterprise-grade?

M$ used to ship operating systems with no security whatsover out of the box. They may be a little better now but they still ship terribly vulnerable software. Every month M$ fixes another bunch of vulnerabilities in their software with no end in sight. The latest had multiple privilege escalations, denials of service and disclosures of data… and that’s both in their client operating system and office suite.

enterprise-grade services and support whereas other vendors did not?

I’ll bet there are a dozen vendors of better software for their purposes. Even Debian does better than M$ in supporting end-users. Where was M$ when my machines wouldn’t run without crashing and malware was eating them up and users were complaining they were slow? M$ ships stuff with no guarantees at all, same as Debian. How is M$ any better than that? How is M$ better than RedHat, Suse, IBM, etc. ?

I would bet the folks who made this decision are either on the take or not thinking of the cost of locking in colleges, students and staff to the Wintel treadmill for years to come. Yes, the cloud is a logical solution to some problems of IT in education but M$’s client OS negates most of that. Then there is the vendor lock-in, file-format lock-in and cost. Did they consider the cost of M$’s licensing fees or was money no object?

PS: When I wrote this, I tried to read the guy’s CV. The page would not load…
“Oops! Google Chrome could not connect to www.aicte-india.org
Try reloading: www.­aicte-­india.­org/­downloads/­cv/­Mantha.­pdf”

That inspires confidence. In 2009, the government of India threatened to close down this organization. After some reforms they were allowed to continue. Perhaps this move will prompt further reform, like getting rid of the folks who made this decision.

Malaysia To Revamp IT in Education, Slowly

“The Ministry will focus on delivering more ICT devices that are not necessarily computers (such as tablets or smartphones as digital devices continue to converge) to students and teachers. In order to remain cost-efficient, the Ministry will innovate along several dimensions. Firstly, it will investigate acquiring fit-for-purpose devices. The Ministry has already made good progress in this area, for instance, through its use of thin-client computers (low-end computer terminals with limited functionality while relying on servers to provide computing power in order to reduce costs). It will also experiment with utilising new, less resource-intensive alternatives for ICT facilities compared to current computer labs, such as a lending library for notebooks and computers-on-wheels. This will become increasingly important as ICT becomes more mobile and the entire school becomes the computer lab.

In addition to assets and physical infrastructure, the Ministry will review the current procurement process to address existing concerns regarding the maintenance and the lifecycle cost of ICT devices, as well as the replacement policy of existing inventory of ICT devices. It will also consider new innovations in procurement such as direct-sourcing from manufacturers, rental agreements and private partnerships to drive down costs.

The target is to achieve a minimum ratio of one computer for every ten students. This will provide students with sufficient computers to be able to learn how to use ICT as well as take advantage of innovations to support broader learning.”

see Preliminary Report – MALAYSIA EDUCATION BLUEPRINT 2013-2025

They have a long way to go with the target for 2020 being at most 10 students per computer but they see 1:1 as an eventual possibility. Of course, Moore’s Law and FLOSS are working for them to reduce costs and they already value thin clients. I have long held that computers are the best/fastest/cheapest means of creating, finding, modifying and presenting information and that they should be widely used in education. In Malaysia, IT is so scarce that only ~75% of schools have computer labs these days but the nation has a plan to promote FLOSS so their cost of acquiring IT should be about half what it would cost if they used that other OS.

Basic infrastructure like electricity and networks are also scarce. Combined with educating teachers in how to use IT these are a broad barrier to progress but one which can be overcome with the determination exhibited. They’ve identified that they are spending far too much on head-office rather than on the front lines, so there is hope that this is not just window-dressing. Malaysia is deploying Chromebooks and Google Apps.

Small Cheap Legacy PCs Eat Big Expensive Legacy PCs’ Lunch

According to IDC, “The volume of thin client shipments in Europe, the Middle East, and Africa (EMEA) in 2012 increased by 9.2% year on year to more than 1.7 million units, according to results published by market research and advisory company IDC. In the coming year, IDC expects thin client shipments to maintain stable 6.2% growth over 2013.”see EMEA Thin Client Market to Grow by 6.2% in 2013, IDC Predicts – prCZ24027913

While the usual desktop/notebook fare is declining or barely holding share, thin clients as another form of small cheap computer are growing steadily. That’s smart. In schools where I worked the thin clients did most tasks better than legacy thick clients because of file-caching in RAM on the servers and were absolutely trouble-free. Compare that with needing so much manpower to manage just a few PCs running that other OS as usual. While thin clients are still a minority of PCs, their long lifetime effectively displaces a significant number of units of legacy PC production. They can run GNU/Linux, too, with no effect on performance, no matter what OS or application is run, except stuff like full-screen video. That covers a large swath of personal computing.

Of course, I recommend Debian GNU/Linux on the terminal servers because it does not require a licence per seat. Debian is about to release version 7.0 and it works really well with a tiny bug-count. There’s no time like the present to switch to thin clients and GNU/Linux to give a new lease on life to a fleet of PCs.

Surprise! The World Can Make Its Own Software

Part of the problem with the Wintel monopoly is the false assumption that large US companies have the best solutions for everything. It’s not so.
‘Wandering into an 11th grade high school class he found kids were studying the following problem: “Given a data file describing a maze with diagonal walls, count the number of enclosed areas, and measure the size of the largest one.”’
see Vietnamese high school kids can pass Google interview.

I have seen this in many of the schools in which I taught. I would go in and be told by the principal that “the students are weak” or “that will be too hard for them” and it’s just not so. IT/computer science is basically very simple: break a problem up into pieces small enough to be described in a programming language and turn the beasts loose on it. That’s exactly what kids have been doing since the age of 3 or so.

I remember one school where a principal sat in on one of my classes and solemnly told me that the lesson was way over the heads of students. Those students solved Naughts and Crosses in three days by two different methods working in a FLOSS manner sharing code and ideas back and forth. By the end of six weeks they had accomplished most of the high-school curriculum for computer science in that jurisdiction and they weren’t computer science students. They were technology students. Using Pascal, a language designed for teaching such things and almost trivial to learn, students practised problem-solving with IT rather than spending the six weeks learning to use some application.

I investigated what other teachers were doing with the given curriculum. They spent several weeks teaching how to use Visual Basic… rather than teaching IT. News Alert! Teachers are not supposed to be salesmen for big corporations! I had students master the basics of Pascal the first week and they never slowed down. I gave them three problems to solve, each of increasing complexity and they were able to solve them by the end of six weeks using all the techniques of the whole high-school computer science curriculum. Their computer science curriculum was three years of deadly boring stuff where they waited for years to introduce the complicated subject of “functions”. In the technology courses, teachers were encouraged to teach multiple modules in parallel, something few did because it was easier for the teacher…

One of my standard lessons to students was to demonstrate the tremendous power of computers that were “old and slow”. They immediately see that M$ has been burdening PCs with bloat for decades trying to slow them down to sell more licences… That’s not a recipe for good IT. Even an ancient PIII is a powerful tool when unleashed with GNU/Linux.

Many teachers in North America have been taught and use methods that just don’t work for IT. The last thing they want to teach are “brute force” methods because they are “not elegant” etc. Guess what? A maze with diagonal sides is just a series of triangles and students in Grade 8 or so are quite familiar with triangles… so the problem that amazed Google’s guy is really quite trivial given the computer’s innate ability to process lists of things. In some ways, mathematics curriculums have overtaken computer science curriculums in respecting brute force. Computers are rather poor at dealing with grand ideas. Limiting IT in approach is foolish. Let computers keep things simple and they fly.

Given a school where M$’s stuff is the only way to do IT and one that embraces FLOSS, guess which students learn more and faster? The students using FLOSS. The world can make its own software quite easily using FLOSS techniques. There is absolutely nothing big corporations have to contribute to that. Just look at M$’s issues with H1B visas. M$ is importing talent because it can’t find enough in the education IT system that it spread through the USA. There are many more clever people around the world than are found in big US corporations.

I recommend using FLOSS for everything: education, business, personal applications, servery, databasery,… It all works. Try Debian GNU/Linux. If there’s something missing from their repository you can likely find FLOSS on the web that does what you want or you can make it yourself or with help. I only have a few pieces from outside Debian and they are all FLOSS. I do far more with IT than the typical old fat guy. I don’t let Wintel hold me back. Why should you?

India’s Aakash 2 In Production and It Looks Good

“A new government tender is expected by January 2013 for five million units, with "up to a million" units targeted by March, according to Datawind chief executive Suneet Tuli. Ministers may appoint multiple suppliers for this next order.”

see BBC News – Tablet computer: Aakash upgrade in India 'well received'.

It took a little time but the small and really cheap tablet PC intended for 220 million students finally seems ready. The specs are competitive and the price is right at $21 after subsidies. Five million units next year will make a dent in the Digital Divide in India. It should do wonders for Indian education, government and economy as well. Within a few years some of these users will be in a position to choose and this may well plant a seed for FLOSS generally.

Debian Edu – Interview: Angela Fuß

“Which strategy do you believe is the right one to use to get schools to use free software?

I am really convinced that in our school project "IT-Zukunft Schule" we have developed (and keep developing) a great way to get schools to use Free Software. We have written a detailed concept for that so I cannot explain the whole thing here. But in a nutshell the strategy has three crucial pillars:

  • We really take time to get what sort of stories, questions and concerns the schools head and the teachers have about using different kinds of IT and we take time to enrol them into Free Software.
  • Our solution for schools is never just technical. In the centre are always the people who are going to use the software. From the very beginning of the planning for a school, we tell the schools head that they are paying us not only for a technical solution for their school, they also pay us for leading all the communication processes needed. If they do not want that, we are not working with them because we cannot give a guarantee for the quality of our work then.
  • Another focus lies in the training of teachers and students in co-administrating the IT-System at their school. They start getting in contact with the Skolelinux / Debian Edu community and they get the offer to become more and more independent from us.

see Petter Reinholdtsen: Debian Edu interview: Angela Fuß.

There, you have it, a recipe for successfully migrating a school to GNU/Linux. It is vitally important to have all users sharing information about motivations and resources available. In my experience younger teachers are most accepting of the wonderful resources of FLOSS available with GNU/Linux. Some older teachers I have known did not even want to use any PC… Many more want nothing to do with IT except routine stuff like writing memos and e-mail. A school thrives when teachers and students all want to make the best use of IT to get education done. In most schools students are the greatest resource in IT but the least used. Putting that youthful energy to work is key. Teachers can lead, follow, or get out of the way…

OLPC Comes to Canada

Belinda Stronach is promoting use of OLPC (One Laptop Per Child) in aboriginal schools in Canada. I can relate to that. In many aboriginal communities, the ratio of students per PC is ~10 when most educators seek a range from 1 to 3. OLPC Canada is getting started with a first goal of 5000 OLPCs. It’s just a start. The need is at least 100K. OLPC has the advantage over using recycled desktop PCs, the solution I used, because they are a better size for small children and their classrooms.

“One Laptop per Child (OLPC) Canada
A core program of The Belinda Stronach Foundation (TBSF), OLPC Canada strives to empower Aboriginal youth to play an active role in their own education through access to learning centered technology. Canada’s first National OLPC program, TBSF has provided approximately 3600 laptops to children 6-12 years of age in rural, remote and urban communities. For more information about the international OLPC movement, please visit one.laptop.org
OLPC Canada is a testament to the strength of partnerships and the important role the private sector, government and NGOs can play in strengthening communities and strategically investing in Canadian children. The program has been generously supported by Vale, BMO and the Government of Ontario.”

The Digital Advantage

Gartner has a new book out that you can read for $0 and no registration required. It’s about the advantages businesses can have over their competition and for their customers by improving efficiency, allowing for growth, and improving performance by doing what was done by paper and face to face communication by digital means. The book contains examples of some remarkable successes that leave competitors in the dust.

The basic idea is that the more an organization can get computers to do things the faster and more efficient will be every operation. I have done this in my own way in education.

  • I used digital books from Gutenberg.org, and made my own documents and the software we used available to students when and where they needed them.
  • I used digital lessons so my students could learn at their own pace and I could teach more subjects/classes/lesson simultaneously. My record was 14.
  • I used digital data in pictures, databases and files so that year to year students, teachers, the school and the community could accumulate information to improve relevance, preserve vital information despite turnover of staff, students and elders, and to allow students and teachers to define their environment individually. It was also searchable saving countless hours of wasted time flipping pages and referring to inadequate indices on paper.
  • I used several times the average classroom’s contingent of PCs to make IT useful rather than just present and to make IT available when students needed it, not according to a schedule.
  • I used software as most teachers used books by having a local library that could be invoked in seconds by the teacher or student thanks to the huge repository of Free Software provided by Debian. Besides the dramatic effect seen by students and teachers, I who maintained the system had most of the work done upstream by the Debian developers and package maintainers. All we had to do locally was choose a few packages and the rest happened like magic.
  • Even our PCs were digital, not just in the way they operated locally but on the network. Data could be anywhere, computing power could be anywhere, display could be anywhere and storage could be anywhere.

Were the results of using digital everything in schools positive? Certainly. Just the savings in paper justified the small effort required. Further benefits included being able to deliver a customized programme of study to students even in remote/small/impoverished schools. Not having to schedule trips to the lab or library were a bonus, saving many hours every year. Typically schools where I taught would have students visit the lab at least once per day for about 1h. That’s beneficial but skipping the transit time, opportunities for mischief, and making IT available at the moment students needed it, “catching the wave”, really made teaching and learning much easier.

Most amazing of all the results was that multiple improvements in performance could be achieved with little or no effort and $0. Older PCs are perfectly suitable as long as there are a few newer machines to do the work and storage (via LTSP). Older PCs are discarded by government and business on schedules so they can be obtained by schools for $0 and freight. The software from Debian is a free download. Chief obstacles lie in teachers not knowing about this possibility or knowing how to do it. All the information is available if you know where to look. Another obstacle is that some teachers feel that using computers takes jobs from teachers. There’s no evidence of that. Class sizes are fairly constant. There’s still a lot teachers cannot do. The important point is that IT allows teachers to do a better job, applying their skill/knowledge when/where it can do the most good. My classrooms functioned best when students were doing most of the work and I could give them instant feedback on what they were doing. The only effort on my part was a few hours to set up equipment usually before school started and the usual planning for education which increased only because I was offering more courses. That did not greatly increase my load because I often taught some courses in one semester and not in another. By being digital, I could plan at the beginning of the year and have both semesters covered so I just advanced the pace of planning, not doing more planning.

Gartner even touches on the subject of businesses that hate or cannot give away anything “for free”:
“So what is the digital strategy for those enterprises?
It is a strategy based on defining a new path — one based on building a digital edge by combining the digital and physical worlds rather than substituting one for the other. Those combinations increase the accessibility of new sources of customer value to expand the potential of digital business. Defining value at this digital edge also helps to create addressable revenue that reflects the best of the digital and physical worlds. The process begins with expanding the definition of value in a digital world.”

That works for schools too. IT is not a substitute for any part of education as it is a better way to do much of what education attempts to do without IT. The bottom line is that education is more valuable to students, teachers and society when it’s flexible enough to meet needs and as efficient as it can be. There’s nothing more efficient than having electrons doing much of the work of creating, finding, storing and presenting information. That leaves people to do the really important things like imparting values, helping, sharing and generally making the world a better place. With GNU/Linux that’s all so much easier.

B.C. to offer free textbooks online

“The B.C. government is offering free online textbooks for post-secondary students who are taking the 40 most popular courses.

Advanced Education Minister John Yap says up to 200,000 students could save money next year”.

see B.C. to offer free textbooks online – British Columbia – CBC News.

That’s a lot like the FLOSS (Free/Libre Open Source Software) ecosystem for software. Invest ~$1million per annum in generating on-line textbooks and save students ~$200 million per annum in expense. It lowers the cost of education. So does FLOSS. Invest a little in installing FLOSS and get all the benefits for very little. Organizations as large as governments could invest in generating FLOSS as well as free textbooks.

Giorgio Pioda: “Every Monday we had 20 machine to fix for viral infections”

Different organization. Different country. Different language. Same problem. That other OS makes itself useless to schools by giving a home to malware. That was the last straw where I last paved over a school full of XP machines.

We decided to move to Linux because students at our school have own laptop and we have the responsibility to keep the laptop ready to use; we were really unsatisfied with Microsoft since every Monday we had 20 machine to fix for viral infections… With Linux this has been reduced to zero, since people installs almost only from official repositories.

Celebrating GNU/Linux

I am an unabashed proponent of GNU/Linux. The reasons are many:

  • Switching to the OS saved my sanity at a point in my teaching career when I was dealing with 20 students from grades 9 to 11 and with a wide variety of levels of ability in Canada’s Arctic. I needed PCs to work in my classroom and hardly a class went by without Lose ’95 crashing. I used the divide and conquer approach to managing that classroom with several activity centres running simultaneously. I was spread too thin to have to help students with problems with IT.

    I switched to GNU/Linux and had no problems of that kind for six months. It was a heavenly experience. Despite having never used GNU/Linux before, the biggest problem for me was downloading and burning an .iso to CD on a Mac. Continue reading ‘Celebrating GNU/Linux’

Evolution of IT in Estonian Schools

In 2004, it was reported that 47% of servers in schools were GNU/Linux but only 3% of PCs were running GNU/Linux. In the face of that Tiger Leap resolved:
“Tiger Leap Foundation has decided that all future software projects supported by them must be released under the terms of GPL (for source code) and Creative Commons (for learning content)”

see Open source software in Estonian schools – Hans Põldoja (2005)

Now, Tiger Leap will implement a Grades 1 to 12 computer programming strand in schools starting with a pilot. While the emphasis is on FLOSS they seem to be ecumenical on OS by using web applications heavily.

My Mission

My observations and opinions about IT are based on 40 years of use in science and technology and lately, in education. I like IT that is fast, cost-effective and reliable. I do not care whether my solution is the same as yours. I like to think for myself.

My first use of GNU/Linux in 2001 was so remarkably better than what I had been using, I feel it is important work to share GNU/Linux with the world. I have been blessed by working in schools where students and school systems have benefited by good, modular software easily installed in most systems.

I have shown GNU/Linux to thousands of students and hundreds of teachers over the years and will continue in some way doing that until I die in spite of the opposition.
