2017 ACM-ICPC Philippines Southern Luzon

I was a problem setter and judge for the 2017 ACM-ICPC Philippines Southern Luzon Invitational Programming Contest held last October 1, 2017 at the Ateneo de Naga University. Seven teams from five schools joined, which is much less than the numbers in the previous years (15 teams from 9 schools in 2016, 13 from 6 in 2015, 31 from 13 in 2014, 32 from 15 in 2013). The contest problems and solutions are here. I provided two contest problems: ā€œCā€ (Sharkovski Successor) and ā€œDā€ (String Substitution). I was also a problem setter and judge in 2016, 2015, 2014, and 2013.

Translating Filipino to Filipino?

This semester, I am teaching an undergraduate class in Filipino. (The course is called “Matematika sa Makabagong Daigdig” or “Mathematics in the Modern World.”) I was trying to say “When was the concept of zero invented and accepted as denoting a number?” in Filipino and I came up with “Kailan inimbento at tinanggap na nagtutukoy ng isang numero ang konsepto ng sero?” I entered it in Google Translate to see how it would translate it. But instead of translating Filipino to English, it seems that it was set up to translate English to Filipino. I was surprised with the sentence that Google Translate came up with (“Anu-ano ang mga halimbawa ng mga tula tungkol sa wika?” means “What are the examples of poems about language?”).

I made a small change to my sentence (using “naimbento instead of “inimbento“) and Google Translate came up with “Sinu-sino ang mga pilipinong nagtaguyod ng pangatnig?” which I would translate as “Who are the Filipinos who established conjunctions?” However, it seems that Google Translate has a different translation.

Tuk-tuk 2

In my hurry to buy the Majorette Tuk-tuks I saw last October 22, 2017, I didn’t realize that there were four color variants for that series. I went to the store a week later and was able to buy the fourth one.

Note that the blue one I blogged about earlier has silver wheels and a red windshield frame; the one above has yellow wheels and a yellow windshield frame.

I was also able to buy the two color variants of the Majorette Auto Rickshaw. According to the Majorette Diecast Database, it seems that the four Tuk-tuks are intended for sale only in Thailand, while the two Auto Rickshaws are intended for sale only in India.
