The Google-Docs typeset version of the book “Practical Data Structures and Algorithms,” in English is released here; this book is still under preparation – so once the proofs are completed a PDF will be released. People interested to collaborate can drop me a email at email@example.com
Over the course of this year, since translating Ruby Kin, and preparing a summary of 3 years work on spell-checker for Tamil Internet Conference – 2019, I’ve been thinking of next level of interesting projects.
The following have come to mind, expressed in Twitter @ezhillang in various forms. Here they are in simply chronological order,
Translating “Data Structures and Algorithms” book in Tamil
Problem Solving with Algorithms and Data Structures Using Python, Creative Commons licensed by its authors Brad Miller and David Ranum; same book (from above) adapted at Bradfield CS https://bradfieldcs.com/algos/
Translating/Writing a “Debugging Techniques” book in Tamil: ‘கணினி செயல்முறை நிரகளில் வழுநீக்கம்‘ – பயிற்சி, நூல்
Debugging techniques are important learning milestone for any professional software/hardware developer which are usually learnt on the job and essentially skipped in academia (perhaps for practical purposes).
(Research/Proof-of-concept) Viterbi algorithm based spelling correction algorithm for Tamil
(Research/Proof-of-concept) Concordance based context ambiguity resolution for Tamil spelling correction.
Contingent on our levels and degrees of success we can share our work in forums like Tamil Internet Conference, ACL or ACM, etc.
As always collaborators are welcome: email: ezhillang -AT- gmail -DOT- com

Java and Open-Tamil : Write Tamil Applications using Java
I’m sharing a small example; you can download (from Github) the whole Java package and include it in your desktop, mobile or web app. For Free! Example gist follows.

Concluding my recent trip to Chennai, I am happy to report my two speaking engagements
were well received at SKP (Thiruvannamalai), and SRM (Kattankulathur). I’m always indebted to the wonderful reception of the hosts and Tamil hospitality they extended to me.
At SRM, Dr. Ila. Sundaram received me and signed a gift copy of his recent book, “தமிழ் கணிமை“. We spoke about documenting the history of Tamil computing; Dr. Sundaram emphasized need for developers and language experts to work hand-in-hand. Later, I spoke with Computer Science professor Dr. Poovammal, and other faculty who were very enthusiastic about adopting computational linguistics as project topics for their final year (senior) students.
The virtual-hosts (no pun intended 🙂 ) Mr. Nagarajan, and Mr. Ravishankar, organized the travel and speaking engagement at SKP college in Thiruvannamalai; it was an eventful trip as I met Mr. SKP Karuna, and various faculty at his institution. Mr. Karuna gifted me a signed copy of his book, “கவர்னரின் ஹெலிகாப்டர்“, among other niceties of the invitation; we spoke briefly about my meeting with writer Appadurai Muttulingam, who has also written the foreword for his book. On the long ride from Thiruvannamalai, I found his story, “கலர் மானிட்டர் (color monitor),” to be entertaining and funny; area of a triangle with a perimeter s needed some typographical fixes & -> ‘-‘. I enjoyed a few other short stories in the collection.
My primary messages to the first- to final year (4 year program) engineers were,
You are a creator; think of every application you use from role of a developer
Engineering allows you to create with social responsibility
Language software needs to be developed with Tamil (or your-native-language) as primary focus instead of only localizing other software
Use open-source tools like open-tamil as a foundation for your Tamil software; this library is supported for Python and Java languages with free licensing model
I spoke about github, 2 years of open-source development, and our collaborators – Arulalan, Shrinivasan, Sathia, and others.
Tamil language and Tamil computing have a long history, and lot of unsolved hard computer-science problems; you have a good chance of putting your mark on these problems, and having a great impact.
Due to time constraints I was only able to make a Skype interview with SRM Computer Science engineering folks, whereas I traveled to SKP College for my presentations. At SRM I was impressed by some thoughtful questions and answers on Tamil software adoption/usage. At SKP the speaking engagements was in 2-parts; the focus group engagement with Center-of-Excellence students was admirable for their knowledge and skill in developing Android applications in various education/geo-location based applications.
Consider Sharing your Expertise
My note to professional engineers and senior engineers in the community seeking to have impact on next generation of Tamil software developers is the following,
Definitely reach out to the staff/faculty/administration of the various engineering institutions in Tamilnadu; you are fulfilling a social responsibility role. Reach out to various administrators on Twitter/Facebook or via email etc.
I recommend you to freely mix your language between Tamil/English to convey the message; written/spoken forms of Tamil have that dichotomy, and besides your audience will follow both forms easily.
Talk more about engineering challenges of Tamil computing; how doing this work is creatively challenging
Motivate the students about their potential, capability, and limitations
Motivate students on multiplicity of several roles in software development:
Requirements specification Analyst
Liason/Analyst – Customer focus
Use a slide-show to aid your talk/presentation
Show concrete examples of software with demos/audio/video
I’m very hopeful that young students, men and women, who are future India, future Tamil speaking developers and users will participate in a software market in buying/creating and using native Tamil software primarily developed for Tamil, not just localized for it.
Unfortunately on the return flight, I misplaced my phone and lost it; unless I receive the device from lost-and-found I maynot be able to share some useful audio content from both presentations. Please hope I do get the phone. More later.
