The Philippines in Top Coders
A visitor posted something on the shoutbox that caught my attention. It’s a statistics on country rankings for developers by TopCoders. In that list, the Philippines was ranked last at number 35 with a rating of only 880 for 12 developers. A lot of other 3rd-world Asian countries are ahead of us — Veitnam (Rank: 19, Developers: 29, Rating: 1600), Bangladesh (Rank: 25, Developers: 23, Rating: 1,422), Pakistan (Rank: 34 Developers: 19, Rating: 941) and Indonesia (Rank: 20, Developers: 33, Rating: 1,587).
I check their formula to see how they were able to come up with the ratings system:
The formula below has the property that if all the coders from a particular country have the same rating, then that country’s rating would be the same as the individual ratings. When coder ratings differ, the country rating is based mostly on the top rated coders. The intent is to provide a better way to rank countries than a simple average.
When generating the country rankings we take the individual ratings for active coders from a particular country, sorted in decreasing order. These ratings are given by rating1 … ratingM, where M is the total number of active coders from a country.
R = .87, this means that the top 10 coders contribute about 75% of a country’s rating.
Although the sample size of Top Coders isn’t really representative of the population size of the respective countries, we cannot infer that the ratings/ranking is conclusive.
However, assuming all other factors are equal, it’s not a good sign for us Filipino developers to be at the last of the line.
