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.)
I was a problem setter and judge for the 2016 ACM-ICPC Philippines Southern Luzon Invitational Contest held last October 1, 2016 at the Ateneo de Naga University.
The winning team was from the University of the Philippines, Los Baños. It solved 7 of the 12 problems. (The teams were given 5 hours.) The results are shown below. (The image has been slightly edited.)
If I’m not mistaken, the warm-up problems were the same as last year’s. The contest problems are here. I provided two contest problems: “C” (Billiard Paths 1) and “H” (Billiard Paths 2). (My slides explaining my solutions are here and here.) As you can see from the scoreboard below, two teams attempted problem “C” (and both succeeded), and no team attempted problem “H.”
I was also a problem setter and judge in 2015, 2014, and 2013.

The warm-up problems are here and the contest problems are here. I provided two contest problems: “D” (Freeway Traffic) and “I” (Forest Fire Spread). They are both about cellular automaton models.

I just discovered this speedometer and this chronograph made by Rolex. (Click on the image to see where I got it from.) Do you notice anything unusual? (Hint: The text between the 7 and the 8 on the speedometer reads “MACH 1.”) Continue reading “Rolex speedometer and chronograph”
Stack Exchange Winter Bash 2014 ends tomorrow. I got more hats this time than last year. I like the fact that you can rotate, translate, and resize the hats.
