      Finally? Not finally.

      You've been able to take wikipedia with you for years. Lots of people do it with Tomeraider, but I get the impression there's a number of options. I first did it 2003ish and I got the impression it had been around a while then.

    I would imagine it would be compressed, and since much of the wiki is text it would shrink a lot.
    I'm thinking at 2 GB would do it, which would easily fit on today's flash memory. And for multimedia content such a pics, they cold convert to smaller and lower quality jpeg's saving at least that much.

      Sorry, but I actually know something about this... My job this summer revolved around this issue, and seeing how much of Wikipedia we could cram into about 10 MB. (Hint: OLPC [laptop.org] is using a subset of Wikipedia as its primary out-of-the-box reference material.)

      The images on Wikipedia as of this January are about 76 GB in size. Now, assume we can switch to low-quality JPEGs and cut the size down to 5% of its current - about the size you'd get from switching all the images to black-and-white, in fact. Making that jump is a big assumption, but even that only gets you down to about 4 GB.

      Text-wise, the Wikipedia database containing all current article info (no discussion pages, no history, etc.) is 1.7 GB - compressed. It's significantly larger when uncompressed.

      There - 6 GB total. And that's an achievement...

      • _Very_ interesting. Is the sub-set available somewhere?

          I presume it will be available once the selection/cleanup process is finished - after all, all software on the laptop is open-source.

          The other offline versions of Wikipedia have a lot going for them, too - if you're interested, take a look at Wikipedia 1.0 [wikipedia.org], and lend a hand if you care to. They're a very worthwhile effort, fully backed by Wikimedia and Jimmy Wales, and they're more specifically targeting CD- and DVD-sized versions.

        I think for most PDA apps, you could drop the images entirely. Not necessarily what you want to do for OLPC (I'm presuming y'all are still considering a community server to host it?).

        Are you filtering for only images which the pages you have include, or is that 76G all the images total in wikipedia?

          The figures I gave are for the entirety of the English Wikipedia.

          Community server - I'm not sure what you mean, but since we can't always count on the laptops' having network connectivity, we're packaging a small (10-50 MB), static subset of Wikipedia directly on the laptops' storage, updateable on connection to the network (meaning Internet and/or local school server).

            There's been off and on talk about a "server" / central node in some places that would provide a more reliable gateway to the Internet, storage space, and so on, see http://wiki.laptop.org/go/System_Software#Distribu ted_Filesystem.3F [laptop.org] , for example. I'm out of the loop, so this may've been a pipe dream that wandered off.
            • by EPAstor ( 933084 )
              No pipe dream - unless I'm mistaken, the current OLPC ideal is to have a server in every school. However, the server won't act as a Wikipedia repository any more than each laptop will - except in that it may store additional Wikipedia "bundles" (groups of articles packaged as e-books) locally.

        You didn't compress well enough. The Wikipedia-on-TomeRaider project gets the English Wikipedia (January 2006) down to 2GB with "many images" and to 4GB with "all images". See here [infodisiac.com]. Maybe you should look into producing an open source TomeRaider viewer that would work on your Linux OLPC; TomeRaider is by far the best e-book format around, so this would benefit the OLPC project in many ways.

    While one of the basic strengths of Wikipedia is its updatability, I would question the point of storing all the articles offline. Admittedly, TFA does say it'll sync up the data the next time you go online, but it'll practically eat up all your disk space eventually.

    • "While one of the basic strengths of Wikipedia is its updatability, I would question the point of storing all the articles offline."

      To be fair, there's a plethora of historical data on Wikipedia that probably won't be touched much over the next year or so. Personally, one of the reasons I want a Treo is so I can hit Wikipedia from time to time. But if I could download a version of it today and update it once a year or so, I'm confident it'd be worthwhile even though it's not up to date.

    Wikipedia regularly dumps the entire database, which is available to download [wikimedia.org]. However, It looks like they're having trouble getting them out lately (link is to a September 25 English dump, which hasn't yet successfully completed).

    The compressed dump files are huge, and I wouldn't want to even attempt downloading them without wget or unless a torrent were provided directly by Wikipedia (why is this not being done yet?)

    In 2009 slinging 100 GB data files across the net or between devices should be trivial, but not yet.

    However, I have a truly marvelous demonstration of how to compress Wikipedia, which the margin of this comment is just barely large enough to contain:
