SeppoErviala··on 1.85% of Steam users run Linux
I didn't use Steam since switching to Linux in 2008 until now that it is officially available. Some of that 1.85% are new (or returning) customers.
SeppoErviala··on A Programmer's Guide to Data Mining
Check out gensim if you want to do topic modeling or similarity comparisons in Python.

http://radimrehurek.com/gensim/

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 is the new beginning after the burning platform company has finally been sold to Microsoft. Alternatively the new beginning for maemo/moblin/meego/whatever.
SeppoErviala··on Making a Living Collecting Cans
Our families and countries work differently.

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.

SeppoErviala··on Making a Living Collecting Cans
If you show initiative and return the cans you can obtain money that would not be available otherwise. Pretty straightforward in my mind.
SeppoErviala··on Making a Living Collecting Cans
I think one of the reasons for returnable cans and bottles is to teach children about money and work. Many people I know once ran the can business in their household as children.

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.

SeppoErviala··on Making a Living Collecting Cans
In Finland, one gets 0.15€ per can returned and slightly less/more for different kinds of bottles. It is very easy to return these since every grocery store has a return machine and one can just take the money without buying anything.

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.

SeppoErviala··on What I've been up to for the past year
There are multiple music store providers and a musician should have presence in all of them.

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.

SeppoErviala··on French Gendarmerie: "Open source desktop lowers TCO by 40%"
"About 3 million computers get sold every year in China, but people don't pay for the software. Someday they will, though. As long as they are going to steal it, we want them to steal ours. They'll get sort of addicted, and then we'll somehow figure out how to collect sometime in the next decade." - Bill Gates @ 1998
SeppoErviala··on Lossy PNG
Only reason GIF is still alive is its animation support. APNG and WEBP+animation are not there yet.

8-bit palette and crappy compression do not matter when you offer exclusive features.

SeppoErviala··on Google Reader shutting down
Thanks! This should really be listed in the HN/rss page.
SeppoErviala··on Seamless Transitioning from Google Reader to feedly
I want a google reader replacement but this requires me to install something instead of just working.
SeppoErviala··on Google Reader shutting down
I would like more powerful filtering options and better recommendations. For example, Hacker News feed is impossible to follow as RSS on reader as it has too high volume (for me at least). I would be content with ~40 daily recommendations.

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.

SeppoErviala··on Google Reader shutting down
No localization, I'm not too interested in USA news.
SeppoErviala··on Google Reader shutting down
The petition will not help.

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.

SeppoErviala··on Google Reader shutting down
I have plenty of feeds that include ads. Reader shows all images and links that are part of the feed body so not going to the site should not be a problem.

If an ad supported feed provider fails to add ads to their feed they just do not understand the medium. One of the core ideas in RSS is to avoid visiting all the subscribed sites!

SeppoErviala··on Google Reader shutting down
I for one welcome this change as an opportunity for growth. Google has not put any effort into reader for some time now. Maybe some innovative company will get the google reader user base and build something great.

OTOH I do feel sad that reader is gone as it has been a part of my daily life for many years now. Some say that RSS is dead but I cannot find any alternative to feeds I've collected.

SeppoErviala··on Why Watching DVDs on Linux is Illegal in the USA
This is not limited to Linux but affects all players that use libdvdcss. For example, Windows and OSX versions of VLC come bundled with the library.

SeppoErviala··on Inherit the Cloud: Who gets your Google Docs when you die?
You could just put all your passwords into a place where they are accessible after your death and your relatives can access your accounts regardless of any TOS you've clicked through.
SeppoErviala··on Self-Host Everything
The English language has a lot of quirks where the pronunciation doesn't match the spelling or two words are pronounced the same but are spelled differently. This disparity has been enforced by the school system and media publishing gatekeepers for a long time but now that anybody can publish anything on the net a more loose way of spelling is proliferating. It will probably just get worse over the next few decades.

My favourite is guessing whether there is an s or c in some words, sometimes it feels completely arbitrary. I cannot count how many times I've misspelled 'choice' (actually misspelled it just now but the spell checker caught it).

SeppoErviala··on Amazon vs. Netflix: Streaming Battle Heats Up
I guess Netflix is phasing out their disc service because it seems to be a US-only thing while they are aiming to be an international video streaming provider.

Amazon streaming service seems to be only available in the US while Netflix is aggressively expanding internationally. Netflix also makes it really easy to circumvent their region coding system to get an access to their full catalogue.

While online streaming services have been available for ten years they all have been either too expensive or had too small catalogue or both. From my point of view Netflix is the first real alternative to pirating in my region. I expect them to capture the same kind of popularity as Spotify did. They still suffer from having very few finnish titles but they are shaking up the status quo here.

Amazon has yet to offer their alternative internationally. And if Netflix can capture people as well as Spotify did, Amazon will have very hard time convincing people to switch

SeppoErviala··on The joys of having a Forever Project
It's an useless effort to build a new free operating system kernel now that GNU Hurd is just around the corner. What chance you have to compete with those MIT hackers? Besides, monolithic kernels are so 80s.

Even if you're building something that someone famous is building they may still lack commitment or vision to get it finished properly. Anyway, if you build it you will at least get it off your mind and get the feeling of accomplishment.

SeppoErviala··on Tron Legacy (2010)
Maybe she hadn't used fsn ever but could tell from the file system structure that it was in fact a UNIX system. Then she concluded that she need to find the correct file - which is how UNIX does things.

I did find the scene ridiculous at the time but it was because I didn't know UNIX or fsn. Now I find it very plausible.

SeppoErviala··on Stuff (2007)
Attitudes toward stuff change slowly because you learn them from your parents.

My grandmother used to save everything starting from plastic bags, strings, plastic food containers, used nails and screws to electricity, water, heat and money. I suspect it is because when she was young there was a serious lack for everything from food to building materials.

I can see the same attitude in my parents except that they hoard a bit more expensive stuff like books, tools, electronics, music containers and furniture.

I used to collect electronics, music, comic books and MTG-cards but at some point I just stopped. The need to collect more stuff that I had learned from my elders wasn't useful anymore. It is also apparent that some companies are trying to market and exploit this behaviour for their own gain.

I still own too much stuff to fit in my apartment. I find it extremely hard to throw away 'perfectly good' stuff if I feel that it could be useful to someone. Yet it is quite laborious to sell it or to find someone who needs it.

SeppoErviala··on PHash - open source perceptual hash library. image/video fingerprints
I recently tried out pHash and it seemed to be a good tool for detecting nearly duplicate images. Certainly superior to calculating md5 for images and comparing those.

However, if the images have different cropping, slight rotation or different brightness/contrast setting pHash didn't seem to work well enough. I got better results with http://www.imgseek.net/ for my image set.

SeppoErviala··on Amazon's top selling laptop doesn't run Windows or Mac OS, it runs Linux
Why would it matter to users what kernel is being run?

The great thing about Chromebook running Linux is that more work is put into Linux kernel, Linux harware supporting and Linux software support.

Linux is not GNU. Locked down devices were explicitly allowed when kernel devs opted to keep GPLv2 instead of moving to v3. They don't care about openness of devices but about the source code.
