Software Freedom Day 2018 Chennai – Minutes

Our friends in Free Software Foundation TamilNadu organized Softwre Freedom day 2018 in Chennai. I participated and put a stall for Kaniyam Foundation and its activities. I explained on,, Tamil TTS, Ezhil Language, Open-Tamil library etc.

There were around 20 stalls. From Free Software Philosophies, Wikisource, Wikipedia, Privacy, Machine learning, Self hosting, Libreoffice, Olipedia, Libre Library, Games, GIMP, Inkscape, Stelleriam, RISC V, Blue DOT movement, Tamil Computing, OpenStreetMap etc


The stalls are so much informative. The volunteers explained the concepts well. We got around 70 visitors from various backgrounds. They asked many questions and got more information.

We had a QA session before lunch with the volunteers and participants. I answered few questions on Opportunities of contribution for non-programmers. explained about Creative Commons license and how any creator/artist/photographer/musician can contribute to the open world.

Had deep conversations on few new friends on Job opportunities, On creating a social movement on leaving space for ambulances on roads, with a blue light and alert from a traffic police, on contributing to various tamil computing projects etc.

In the evening, got an opportunity to give a talk to the team on the stage. Shared few experiences on mailings lists, how the tamil computing efforts are started and running etc.

It was so enthusing to see the youngsters are working hard to promote the Free Software in all the ways they can. tons of thanks for the Volunteers, Organizing Team, and participants for making the event fruitful to all.

PySangamam – Tons of learnings, Happy moments


PySangamam, is the first Python Conference of TamilNadu.
ChennaiPy team arranged for this two days conference.

Conducting a conference is like arranging for a marriage.
It will take all our time and energy, for few months.

I dont know how to thank the ChennaiPy team, organizers and volunteers for this great event. My apologies for not contributing.

I was following up from their initial discussions about the conference. The hard work they put was so fruitful. We had a memorable days at the event.

I liked the below things.

1. Single Track.
2. Poster Presentation after a lunch time.
3. Neat venue
4. Nice Food
5. Enough amount of participants
6. Wonderful Speakers
7. Awesome topics
8. Video Recording
9. Handson Workshops
10. Event on Friday/Saturday – So that we can enjoy the sunday with family.
11. Nice followups on from Call for speakers, Call for booking etc
12. Great updates on mail on the flow
13. Good followups and retweets on @PySangamam twiter handle
14. Nice goodies – IDcards, food coupons, Bag, notebook, pen
15. Neat Simple website

I did a poster presentation on “How Python is helping for Tamil Computing?”


Explained on Ezhil Language, Open Tamil Library, OCR4WikiSource, FreeTamilEbooks automation, Tamil TTS Automation, NLP Tools for Tamil
Many of them wondered to see such things happening in Tamil. Few agreed to check these tools and contribute.

It was a happy moment to see 4 of the open-tamil contributors met on the poster.  ArunRam, Shrinivasan, Nithya and KraceKumar.

Wondered to see a 7th standard kid explaining on how he learnt Python. Will say about him on all my future python sessions and to all who ask for learning python.

Met my old friends Kamesh, Stylesen, Yogesh. Had nice time with them. Arvind from Elastic got introduced. He shared more new things about the Elasticsearch and

For my surprise, My master, Mr.Chandrashekar Babu was handling a workshop on concurrent programming. I always feel blessed to be in his classroom.
He is one of the main causes for me for being myself. He is always inspiring me with his continuous learning and sharing nature.

Learnt tons of new things in this two days. gevents, generators, yield, opencv, class, meta, async, queue, datastructure, xrange, stack and more. Have to digest them by reading about them and use int he projects I am working on.

As on the PySangamam logo, From Thirukkural – 394
குறள் 394:

உவப்பத் தலைக்கூடி உள்ளப் பிரிதல்
அனைத்தே புலவர் தொழில்.
மற்றவர்கள் கூடி வரும்போது, மனம் மகிழ அவர்களுடன் கலந்து பேசி, இனி இவரை எப்போது, எவ்வாறு சந்திக்கப் போகிறோம் என்று அவர்கள் எண்ணுமாறு பிரிவது கற்று அறிந்தவரின் செயல்.

It is the part of the learned to give joy to those whom they meet, and on leaving, to make them think (Oh! when shall we meet them again).
Realized and experienced this with PySangamam.

I dont have words to express my Thanks.

Waiting to see you all again.

My few clicks are here.  No much clicks this time.



One request for PySangaman team and other conference organizers –

Please arrange a play area for kids, so that parents can come as family and attend the events. Our kid Viyan came along with us. We had to keep on entertaining him with goodies, stickers, notebook, drawing etc. It may be tough things to arrange for a kids area. But it will help to being more women speakers and participants .

Fix wireless on HP 2000 laptop for LiuxMint 19

Today, I installed LiuxMint 19 Tara on a HP 2000 Laptop.

Everything went fine. Bios was plain old. No issues with UFEI. Mint is supoer cool for newbies. But found Wifi was not working.

running “rfkill list all” showed that there were soft and hard blocks for wifi. running “sudo rfkill unblock all” removed the soft blocks.

Pressing the wifi button on F12 was not working.

Here is how fixed with some searching various forums.

  1. Ran this command.
sudo tee /etc/modprobe.d/blacklist-hp.conf <<< "blacklist hp_wmi"

2. Reset bios with default values

Then, WIFI started to work.

Thanks for the awesome opensource community for all the software ans ansers.

30 Project Ideas for contributing to Indic Wikipedia Projects

Last week, I had an interesting meeting with Panjabi Wikimedian community and CIS-A2K team.

Panjabi wikimedia community is small in count. But each of them are contributing with their best. Many of them doing 100-days-of-wiki, personal wiki edithathon for 100 days. Few of them do in in multiple sites and many times a year.

Their interest on contribution and passion on their language is awesome.

Interacted on wikisource, wiktionary and wikipedia. Shared many ideas to improve their workflow. They are looking for many tools to automate their tasks. Those tools will be useful for all wiki communities.

Then, had some great discussions with CIS-A2K team. We spoke about many interesting project ideas.
Listing them all the ideas here.

1. List down the Top 10 tricks/hacks/must know on any wikisource project

2. Make simple tutorials on how to start contributing to wiki, in all possible languages. Still we dont have an ebook or easy starter guide in Tamil. There may be video tutorials. curate them and show them in better way to find them easily.

3. Telegram bot to proofread wikisource contents. Get a page from wikisource. split it into lines, then words. Show a word and OCRed content in a telegrambot. User should verify or type the correct spelling in telegram itself. Submit the changes to wikisource. Thus, we can make the collaborated proofreading easily.

4. Explore how to use flickr for helping photographers to donate their photos for commons. Flickr is easy for them to upload and showcase. From there, we should move the photos to commons. Few tools are already available. Explore them and train them for photographers.

5. We should celebrate the volunteers who contribute to wiki. By events, news announcements, interviews etc. CIS may explore this.

6. Web application for OCR4WikiSource

7. Make a web application to record audio and upload to commons and add in wiktionary words. explore Lingua-Libre for web app.

8. Make a mobile application to record audio and upload to commons and add in wiktionary words.

9. CIS may ask the language based organizations to give their works/tools on public licenses.

10. A one/two day meeting/conference to connect various language technologies. Each team can demonstrate the tools they are working on. others can learn and use them for their languages. CIS may organize this soon.

11. Building spell checkers for Tamil. Learn how other other languages are doing. Odia seems to have good spell checker. Explore that.

12. For iOS, there is no commons app to upload photos. It was there sometime ago. Fix the iOS commons app and rerelease it again.

13. Build Maps with local languages with OSM.

14. One/Two day training on wiki tech. like gadgets, tools, toolserver, API, etc

15. Tweet marketing to promote the ebooks released in wikisource projects. Measure the downloads.

16. CIS may talk with amazon to release the ebooks from wikisource for free always at amazon.

17. Explore Valmigi project of malayalam, chikubuku of kannada – for their ebooks.

18. Download ebooks from dspace, bengali books – West Bengal Public Library Network – url –

19. Explore paid works for wikisource proofreading.

20. Blog on how ta wikisource for 2000 ebooks from TN government in public domain license. Send to CIS. They may try to do the same for other languages.

21. ASI website has info about all monuments. Scrap them all and add in wiki.

22. Scrap details from tourism sites and add in wiki.

23. Kannada archeology site has tons of images but with 3 seals added in all images. scrap them, remove seal and add to commons.

24. Tool to audit wiki sites. like new users, edits, measurements, KPIs, reports etc.

25. Discuss with wiki writers and help them to automate their tasks. Build new tools to help them. train existing tools.

26. Get existing photos from many photographers. Get license doc. Add in OTRS. Have a team to upload the photos to commons.

27. Find the pages that don’t have images. Search in commons and add 1 image automatically.

28. Infobox in wiki pages may have 1 image. Check for the same page in other languages.. get the image from infobox and use it in missing pages.

29. Tito showed a broken JS script. Explore it and fix it.

30. Discuss with victor and google team to improve the OCR feature and integrating with wikisource. Explore existing tools like and


Thanks to Ravi, Tito, Tanveer, Dan, Charan Singh, Manavpreet, Rupika,Gurlaal, Stain for the interesting meeting and great ideas.

We can work on these ideas and implement them soon.

Project Idea – Need a web interface for Tamil TTS

Hello all,


The Tamil TTS system provided by IITM and SSN College of Engineering had one issue. It can convert one tamil string to audio at one time.

Because of this, we can not do parallel conversion. Few full text books took 4-5 hours for conversion. Because of this, we could not make it as a web application for public use.


Mohan helped to make the Tamil TTS Script simpler to process multiple
conversion simultaneously.

Here is the super script that does magics.

Thanks Mohan for your great works.

now, we need to convert this as a web application, so that anyone can
use it easily.

The requirements are below.
1. user registration with gmail
2. user should upload a tamil text file
3. once it is converted, user should receive an email with the link to
the audio file
4. we can keep the audio files for 1 week
5. REPT API support with authentication
6. A queue system

All these will be released in GPL.

If you are interested in doing this, reply here or write to me.
