For the sixth time in a row, I was a problem setter and judge for an ACM ICPC programming contest held in Ateneo de Naga University. Last October 7, 2018, twelve teams participated and their performances are shown below. I guess the low number of participants is due to the two-year absence of new undergraduate students (from 2016 to 2017) due to the addition of two years of senior high school in the Philippine educational system.
I contributed two problems: Problem C: “Symbolic System” (based on the symbolic system described on page 102 of Wolfram’s “A New Kind of Science”) and Problem E: “Fibonacci Ones digit” (based on Rossi D’Souza’s “Where did/do mathematical concepts come from?” in For the Learning of Mathematics, vol. 36, no. 1, pp. 25-27). Only two teams attempted problem C; only one team attempted problem E; all three failed to solve the problems.
Stack Exchange Winter Bash 2018 ends tomorrow. I was able to get 11 hats.
I have a few Hot Wheels Treasure Hunts that I’m not so excited about. If they weren’t Treasure Hunts, I probably wouldn’t have bought them.
This Speedbox is from 2014.
This Tread Air is from 2015.
This Street Stealth is from 2018.
This Zombot is from 2018.
The circle-flame logo is on the robot’s knee.
I was only able to get 13 hats for Stack Exchange Winter Bash 2017. Unfortunately, I had forgotten that it would end today, so I was not able to get images of me wearing the hats. You’ll just have to trust me that I really got the hats below.
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: “C” (Sharkovski Successor) and “D” (String Substitution). I was also a problem setter and judge in 2016, 2015, 2014, and 2013.
I had been planning to buy a digital watch for some time, something metal like the A158WA-1 or the A159WGEA-1EF. I really wanted to get an A159WGEA-4AEF but all I kept seeing in the stores were A159WGEA-9AEF.
But when I saw this Casio F-91W Gold, I bought it immediately. The black resin strap is quite thin, and with regular use, I expect it to last only a few years. From the back you can see that the body is made of metallic beige plastic and it seems that the front has a thin piece of gold-colored metal covering it. It seems that this model is also available with the metal colored silver.
Some time ago, Seiko had an advertising campaign that stated “You can tell more about a person by the watch they wear than anything else” and “It’s your watch that tells most about who you are.” This F-91W gold is simple and special, just like me.
I was able to get only 10 hats for Stack Exchange Winter Bash 2016. (The storm that hit Naga City last December 25, 2016 resulted in the city having no electric power for most of the holidays. My residence still does not have electric power as I write this post.)
