Conferences, in Sri Lanka, Malaysia or Singapore September/October?

I am scheduled to speak at the National IT Conference in Sri Lanka (NITC 2018), 2 to 4 October 2018, organized by the Computer Society of Sri Lanka (CSSL). Are there any other computer, education or environmental events I could attend in in Sri Lanka, or in the week before, or after on the way through Malaysia or Singapore?

On a previous visit to Colombo I talked about "Mobiles and e-learning for PandemicFlu Response" to members of the Sahana Software Foundation, at Virtusa's Colombo Office. In 2015 I stopped off for the Second International Conference on Open and Flexible Education (ICOFE 2015) in Hong Kong on my way to the 10th International Conference on Computer Science & Education (ICCSE 2015) in Cambridge.
