It has good implementations of various algorithms, some of which support streaming or dirstribution, and it allows loading and dumping data in various formats.
I've used it for building content based recommender using tf-idf, lsi and similarity index. After the index is built, queries to it are really fast. It can handle quite large corpuses with little memory.
This scenario doesn't work if the only place to return cans is a recycling center that has no other function and is located at a far away place or if the monetary amount received from cans is trivial. It doesn't work too well either if a child can just pester for money instead of having a fixed allowance + bonuses for work.
In Finland the return amount is currently 0.1-0.4€ per can/bottle and one can return them to the nearest grocery store. For me that was some serious pocket money - even a few bottles could buy some candy.
And it wasn't about pestering my parents to go to the store, more like tagging along when they went. I still had to carry the cans (or at least carry as much as I could if there were a lot) and return them to the machine myself - very different from just getting money handed over.
Anyway, my personal experience from my country of residence is that returning bottles is a good way to make pocket money especially if you can monopolize bottles from your own household and you have poor income.
EDIT: This requires grocery stores to take return bottles, I'm not sure if I would let my children to a hobo-filled recycling center.
The consequence of this is that some people patrol the streets and collect every returnable can they can find just like in this article. However, during summers it seems to be very lucrative business as many people go to city parks to enjoy the sun and some beer. Very few people bother to collect their own cans since one can just toss the can and be sure that someone will collect it within minutes.
I've noticed that the can collecting business is somewhat organized during the prime season. Major parks seem to have groups of people (sometimes quite young, children even) who try to monopolize the can collecting in each park. Periodically there is a car that takes all their cans presumably to a bulk return center. None of these people are ethnic finns.
I'm not sure how I feel about this. It seems horrible that some people venture off from one country to pick up the thrash of others in another country. OTOH the trash problem is reduced and we cannot interfere with the free movement of people within EU.
It seems that DistroKid solves this problem by uploading the music to all the music stores (not really all atm but maybe they will get there). This way musicians doesn't need to study what kinds of hoops they need to hop through to get included in any of the stores.
8-bit palette and crappy compression do not matter when you offer exclusive features.
Google reader had decent random recommendations before the G+ update. I believe that a good recommendation system can guess relevant items for given user, but that was not what google reader has been doing for some time now.
Google already killed reader in their hearths when they made the g+ update. Instead of neglecting it for years to come they did the right thing and let it go for good.
