A Decade Of Service At Groklaw. Thank you, PJ

“FUD withers in sunlight. It only works when people lack accurate information.”
see Groklaw – Happy 10th Anniversary, Dear Groklaw! Happy 10th Anniversary to Us! ~pj

How much FUD GROKLAW deflated:

  • GPL is evil/unconstitutional,
  • Linux was copied from UNIX operating systems,
  • The world owes SCOG, M$, and lots of other parasites per user/user/machine, etc., and
  • Software Patents are good for us…

I must say I felt terribly bad when SCO claimed Linux was theirs to tax. I didn’t fully understand the world of FLOSS in those days. PJ educated all of us with thorough research and detailed legal investigations. Fortunately for the world, the courts finally saw through the smoke and mirrors to the truth. Too bad they still haven’t seen through M$’s smoke, but that gives us something for which to live.

Thanks, PJ. You have done a lot of good work and documented everything so that the search engines can pierce FUD in seconds. Thanks.

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.”
see AICTE favours vendor lock-in, makes Microsoft Office 365 mandatory in Indian colleges | Muktware

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.

edX to be completely open source by June

FLOSS and education certainly go together. FLOSS software is being developed for on-line education by major educational institutions. It seems to be making waves:
“edX, the online education initiative to provide MOOCs (Massively Open Online Courses), which was founded by Massachusetts Institute of Technology and Harvard University, is being reinforced by teaming up with Stanford University. Stanford has been developing its own open source Class2Go platform for online education which it released earlier this year.”

M$ Is The Cancer

When Samsung packaged a solar-powered classroom for Africa’s remote communities, it shipped a GNU/Linux solution but M$ intervened…
“However, this solution with little education relevance (all 20 student laptops as well as the teacher one) was a complete Linex solution at the time of launch.  Working together with Reza Bardien, our Education Lead, we managed to turn this into an end to end Windows solution by the end of the week, including the PIL Learning Suite and the Windows-based NETOP Classroom Management solution.
see Microsoft Citizenship | Solar Powered Schools – Linux Win

This is a failure for Samsung as far as I can see. They missed an opportunity to free an emerging continent from the clutches of monopoly. I have used GNU/Linux in education and it is wonderfully suitable whereas schools should not be tied to a money-making machine like M$.

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?

Computers For Schools Speaks

I received a reply to my e-mail responding to Industry Canada’s evaluation of CFS. Included is this gem:
“Over the years there has been very little requirements for the Linux operating system to be installed on CFS computers. All request we currently receive require that we install Windows 7 as the operating system, we stopped using Windows XP last year. We only install the software our clients request and to date it has only been Microsoft products.”

Well. When I was teaching at my last school we had already converted to GNU/Linux when we made the first of two requests for batches of 20 CFS PCs. I asked them for GNU/Linux and they said they don’t do that. I had to re-image the machines, not a huge chore but wasted effort by CFS and myself. Can education afford to waste manpower on supporting that other OS? I don’t think so. Again, if CFS doesn’t offer GNU/Linux how do they know there is no demand? It’s just like retail shelves stocked with nothing but M$’s OS. How is the retailer to know they have choice? I took the trouble to contact CFS Manitoba to request GNU/Linux. How many computer teachers would do that?

Here‘s the current application form for CFS Manitoba. Nothing at all about choice of OS…

Challenges remain, even in retirement, more windows to close.

The Right Way To Do IT

Quite a few don’t see how FLOSS can be the right way to do IT but it is. FLOSS lowers the cost of IT and the barriers to entry for small businesses and start-ups. That’s good for everyone.

“The digital revolution, also called the third revolution, has changed the entire landscape of the business world. After the industrial revolution, no other revolution has changed the fabric of the society as the Internet revolution has changed it. It has given rise to organizations that thrive on volunteers, peer production, and collaboration. Wikipedia, the Mozilla Foundation, WordPress, Red Hat, and many more are competing today with some of the best financed and resourceful enterprises across the globe.”
see Open source boosts entrepreneurship and social good through collaboration | opensource.com.

In education, the business with which I am most familiar, there is no huge lock-in because ODF, PDF, HTML and such are all widely used standards for documentation and the ubiquitous projector brings everything to light in a classroom or small group project. LANs empower every school using FLOSS to share resources school-wide. Properly exploiting FLOSS is as easy as installing Debian GNU/Linux and searching the repositories for useful software and data.

apt-cache search database
finds such gems as

  • anymeal – A cookbook database for storing recipes
  • piwigo – photo gallery software for the web
  • wordnet – electronic lexical database of English language
  • tracker – metadata database, indexer and search tool
  • tora – graphical toolkit for database developers and administrators
  • redmine – flexible project management web application
  • postgresql-9.1 – object-relational SQL database, version 9.1 server
  • phppgadmin – web-based administration tool for PostgreSQL
  • phpmyadmin – MySQL web administration tool
  • mysql-server-5.5 – MySQL database server binaries and system database setup
  • mongodb-server – object/document-oriented database (server package)
  • libreoffice – office productivity suite
  • dictd – dictionary server
  • apache2 – Apache HTTP Server metapackage
  • …and many more

Only someone brain-dead could not see the possibilities. apt-cache search search finds over 1000 items. No need for budget planning or purchase-order requisition, just a little reading and installation in minutes to try stuff out. Using FLOSS cuts the time needed to set up a great IT system in a school from years to days.

Chromebooks in Schools

It’s 2013 folks, a whole new ball-game. No longer do schools see they have no choice of OS in school other than the most expensive to buy (MacOS) or the most expensive to operate (that other OS). The world has seen Android/Linux on smart thingies and GNU/Linux on netbooks. Now everyone knows they have a choice. OEMs and retailers are getting that.

“We want Google in Education to help open more doors and we’re pleased to announce there are now 2,000 schools using Chromebooks for Education–twice as many as 3 months ago.”

see Official Google Enterprise Blog: A Look Back at 2012: The Expansion of Learning on the Web.

It’s a good start for Chromebooks but with 400% per annum growth expect to see global impact in nearly every use of IT very soon. The key to success of Chromebooks is that Google manages the software so schools don’t need to do that and Google, unlike M$ is not out to enslave schools making them indoctrinate students. It’s all about escaping slavery of Wintel to freedom of FLOSS.

FLOSS In Education Has Grown

Once again, a list has been created of useful FLOSS applications for education. Looking over it, I noticed many of the old standards such as OpenOffice.org/LibreOffice and KOHA integrated library suite and GIMP image processor but was amazed at the depth of more specialized applications like classroom managment and school management. In line with my experience there truly is no reason to stick with Wintel in education.

“To compile the list, the Oxford-based organisation worked with the educational community and with the open source communities around many of the featured projects. The list contains several generic packages, Johnson writes, "but we’ve looked at them specifically in the context of their application to an educational situation, such as using an office package to author e-books."

see List of open source options for education published by OSS Watch | Joinup.

In small schools where I usually worked, FLOSS including GNU/Linux operating systems permit reliable and economical IT limited in function only by imagination of which there is no lack in the younger generation. In larger schools, FLOSS truly flies as FLOSS greatly increases productivity and lowers costs in bulk because there are no restrictive licensing/authentication schemes. Many systems don’t even require a full time IT person because the users can manage the software and only annual cleaning/inspection may require professional IT. In FLOSS, everything can be automated and remotely administered.

Computer-literacy In India

India, with over a billion people and a rapidly growing middle-class is ripe for a rapid uptake in IT yet poverty is still a huge factor in adoption. GNU/Linux and FLOSS is part of the answer to this problem. Another major part are small cheap computers now coming on the market. India is ready to catch the wave. The “Spoken Tutorial” project is the on-ramp to modern IT for people of all backgrounds in India. It is multi-lingual and reflective of many needs and abilities.

“The main purpose of this project is to make India computer literate,” reasons Moudgalya, adding that it is not possible if one relies only on commercial software. “We have to make the most use of open source software like LibreOffice and Latex and OS like Linux. It’s our only solution,”
see Found: Blueprint for a computer-literate India.

While uptake of FLOSS has been weak in some regions, India has many millions of users of IT coming on-line who are not locked in to Wintel. India alone could multiply the users of FLOSS within the next few years. I recommend Debian GNU/Linux to newbies everywhere. It takes a bit of learning to install but it has the flexibility people need to get things done.

Petition US Government to Use FLOSS

There is a petition to USA/Whitehouse to promote Free Software. “SIGNATURES NEEDED BY JANUARY 16, 2013 TO REACH GOAL OF 25,000 23,437

see promote the use of free software in our schools. Libre Office, Gimp, GNU Cash and other GPL software which is cost free | We the People: Your Voice in Our Government.

This is good for education but it should include all levels/departments of government.

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.
