Finland is Winland
… and official stats on last.fm (or lack of them) are lame. But I like stats, because stats are fun.
20 min. of mono coding and 6 hours of profiles indexing later results came. So what’s interesting in last.fm profiles? Mostly country and sex profiles. Every country has similar number of users hiding sex, but m/f ratios are very different. Mainly:
- Finland is Winland: 29.4118% M <-> 70.5882% F
- Switzerland is a don’t-go-there-man country: 92.8571% M <-> 7.14286% F
- General proportion is about 60% M <-> 40% F
Per age: (% of M) minus (% od F):
- unknown = 20.9581
- 13: -5.26316
- 14: -13.3333
- 15: -11.5385
- 16: -4.89914
- 17: -1.96937
- 18yo: 7.89981 (google spam ;)
- 19yo: 22.7621
- 20: 17.5758
- 21: 23.8994
- 22: 32.0197
- and grows… 30: ~70
Young girls like last.fm? Per number of friends:
- 00-05: 25.2016
- 05-10: 22.0175
- 10-15: 8.92857
- 15-20: 15.5963
- 20-25: 8.49673
- 25-30: -10.1449
- 30-35: 7.54717
- 35-40: 6.52174
- 40-45: 5.61798
- 45-50: 9.52381
- >50: -23.0769
Girls have more friends. Splitting friends by country gives nothing and is more useless than this whole post. More stats will follow, if there’s more stuff found.
C# library for interacting with last.fm will be published as soon, as I change separator to something other than “,” (thanks “Taiwan, Republic of China”). Currently it can poll profile details, friends lists, feeds, shouts and aggregate that in db4o.
Are you using the db4o object database for this? What was your experience with db4o?
Best regards.
Really good :)
It was the second time, I used db4o and it was nice and easy. It integrates nicely with C# (at least the latest versions - previous were java-oriented only).
Queries are easy to create and use. Even though I didn’t use it for any public available stuff, it seems, that you can’t hit any typical string escaping problems when constructing them - that’s a plus.
Lazy object activation is also nice.
I just recommend playing around with examples - they show most basic stuff you can do.
Also once you ask about commercial licences, support / sales dept. gets VERY nice :)
