Open-source app releases first complete copy of English Wikipedia with images
- voltagex_ 13y ago> Space required during initial import: multiply the dump file by 8. For example, for English Wikipedia, the dump size is 10 GB. You should at least have 80 GB space free for the import process > Space required when completed: multiply the dump file by 2.5. For example, for English Wikipedia, the dump size is 10 GB. When done, your English Wikipedia will be 25 GB. Ouch, looks like I won't be trying this here any time soon.
- gnosygnu 13y agoYou can try the low-space import. There are instructions in XOWA at home/wiki/Help:Options/Import. It takes longer (8-10 hours) but only needs 35 - 40 GB. (which is still a lot). In the end, you're still going to need about 25 GB for English Wikipedia. If you want something smaller, you can try one of the other wikis (for example, Wiktionary, Wikiquote, Wikisource, etc.) Each of these are generally about 5 GB. Hope this helps.
- jmillikin 13y agoIt's only ~3 GiB once you leave out the articles about individual Pokemon.
- runn1ng 13y agoWikipedia doesn't have that. For most Pokémon, they have summary pages like this http://en.wikipedia.org/wiki/List_of_Pok%C3%A9mon_(252%E2%80%93319) http://en.wikipedia.org/wiki/List_of_Pok%C3%A9mon_(252%E2%80...
- ce4 13y agoIf you don't need the "with images" option, have a look at Aard Dictionary [1], the precompiled english Wikipedia has around 8GB at the moment. It has an app for android also. [1]: http://aarddict.org http://aarddict.org
- 72deluxe 13y agoYou could try the version without images from Kiwix. I keep it on my MacBook (and also at work) to save Internet trips and for when out and about with no access. EDIT: Just read further down the comments and noticed the mention of Kiwix, apologies for the duplication.
- splatzone 13y agoWhat's the main target market for this kind of thing?
- mdda 13y agoMachine Learning
- arthurcolle 13y agoCollectors.
- ics 13y agoOne interesting case I can think of is for institutions which for some reason or another want complete control over article creation/deletion/modification but without the need for recreating the entire knowledge database from scratch.
- gnosygnu 13y agoI personally use it for traveling. There are a few other applications as well: - low-bandwidth availability, particularly in less-developed regions of the world - censorship evasion - security concerns. some users want to access Wikipedia without exposing their machine to the internet There are probably a few others I'm missing....
- greenyoda 13y ago"censorship evasion..." Unfortunately, having your own copy of Wikipedia could also be used to enable censorship. For example, a fundamentalist school could have their own version of Wikipedia from which they've purged all articles about evolution, etc. Then they could configure their firewall to block the real Wikipedia.
- gnosygnu 13y agoAgreed. However, I think it would be less work for them to block access through firewall policy, than to remove them from XOWA. By and large, for most private individuals, an offline app would allow them to evade censorship. I'd hope that this benefit outweighs the risk of the other's abuse.
- EvanDotPro 13y agoI wouldn't mind having something like this for long flights without wifi. Edit: Kiwix looks nice too, thanks!
- sirsar 13y agoSee also: Kiwix For one thing, it has an Android app, and it's easy to put the whole thing on your external SD card. It also provides an index for full-text search. http://www.kiwix.org/wiki/Main_Page http://www.kiwix.org/wiki/Main_Page
- gnosygnu 13y agoKiwix's Android app and the full-text search are both great features. However, I'll point out that Kiwix has not updated English Wikipedia since January 2012. Also, XOWA works directly with the Wikimedia dumps (http://dumps.wikimedia.org/backup-index.html http://dumps.wikimedia.org/backup-index.html) so it's (a) always up to date and (b) can work on any wiki (Kiwix needs to release the zim file first) Also, XOWA can run from an external SD card (including FAT32 formatted ones)
- ddeck 13y agoAnother Android option is Fastwiki [1]. No images, but provides a conversion tool to convert native Wikimedia dumps. Also works with older Android versions. [1] http://fastwiki.qwrite.info/en/index.html http://fastwiki.qwrite.info/en/index.html
- ddeck 13y agoThe Kiwix Android app is great. Unfortunately (for me), it requires Android 3.0+. I spent some time trying to port it to 2.1 for an old large format device I have, but could only get it working on 2.2.
- AjithAntony 13y agoMy use case is exporting a private mediawiki for use at a prison. Kiwix is a lot more polished than this, especially the user experience. This looks interesting becuase reproduces mediawikis very well. The text-only dump imported pretty well once I figured it out. The kiwix ZIM files are a pain to prepare, and use the public facing API that can be pretty unreliable, especially if your mediawiki hosting is of poor quality. It also forces you to hand curate what you export. Using the direct XML dumps prepared server side is much cheaper, but then you lose the curation. The image situation is unclear here. There are some really confusing instructions about it, but I wasn't able to figure it out. I'll keep using and recommending kiwix for now, but this could be promising.
- laxatives 13y agoSince Wikipedia doesn't have ads (and I'm guessing gets no real benefit from number of clicks), maybe this could be a nice way of lightening their server load and reducing some of their costs.
- _nb 13y agoProbably not. In your ordinary browsing, you're not likely to download anywhere near the entirety of wikipedia. Plus, spreading out your requests over time rather than downloading it all at once is more gentle.
- gnosygnu 13y agoGood observation, but I just want to point out that the full dumps are downloaded from different servers. They are even mirrored by other institutions. See https://meta.wikimedia.org/wiki/Mirroring_Wikimedia_project_XML_dumps https://meta.wikimedia.org/wiki/Mirroring_Wikimedia_project_...
- cdash 13y agoThey could set up a torrent as well and almost assuredly people will seed it full time on servers.
- rakoo 13y agoThere is a torrent distribution channel: see https://meta.wikimedia.org/wiki/Data_dump_torrents https://meta.wikimedia.org/wiki/Data_dump_torrents However it suffers the number one torrent issue: they do not tolerate change. This means that - When an article changes, you need to generate a new torrent - When a new torrent describes the archive, it needs to be downloaded from scratch by all peers, so that the maximum number of peers are available for a newcomer. I hope you'll understand that this is not the official way to distribute archives...

- nowarninglabel 13y agoSome people wonder what this is good for. For me, it would have been great, when I worked on a training ship as the IT support. Students were not allowed access to the internet (nor could our meager satellite uplink have supported it), but for my second stint on the ship, I wanted to see if I could provide them with Wikipedia. So, I grabbed the dump, set up MediaWiki, and imported it...and waited...for days and days and eventually the thing loaded, and it was great. But, it would have been super nice to have an easy installer to handle all that. So, yes there are use cases out there.
- evolve2k 13y agoI read the next comment after this and it started with '> Space required during initial..' And I thought ah yes 'Outer Space' that could be another location an offline version could help.
- gnosygnu 13y agoThat's pretty impressive. I never had the patience to sit through a full MediaWiki import for en.wikipedia.org. Just to be clear, XOWA isn't an installer for MediaWiki, but it's own app. This allows it to avoid the dependency on the entire MediaWiki tool-chain (apache, php, mysql, MediaWiki). Unfortunately, this means that XOWA has to reproduce the same logic, which is quite a challenge...
- adrianb 13y agoWouldn't it be easier to include all the original tools in a packaged form instead of reproducing their logic?
- gnosygnu 13y agoYes, this would be the ideal approach, but it can become quite complicated (b/c the tool-chain needs to be installed for different machines). In addition, the official.xml importer (importDump.php) is not really up to the task (slow / sometimes buggy). If you're interested in going this route, you can look at http://www.nongnu.org/wp-mirror/ http://www.nongnu.org/wp-mirror/. This should build a local MediaWiki instance with one click. Keep in mind that it's a bit slow: it takes two days to build simple.wikipedia.org with images. In contrast, XOWA sets this up in about 30 min
- espresso77 13y agoAs a thought experiment, assume you were downloading and printing on low acidic paper (or otherwise storing for the long term) the entire contents of Wikipedia for insurance against some near extinction event. Is there a way to allow future generations to correctly interpret the arbitrary text on a page into meaningful information with only using "the page" as a medium? (I tried googling the topic, but I'm very lost as to even where I should start. The main question that I'm interested in could be summarized as, "How do we ensure our knowledge as a species/society is not lost in an unintelligible format?")
- gnosygnu 13y agoIf you're interested, they update the calculation for printed pages here: https://en.wikipedia.org/wiki/Wikipedia:Size_in_volumes https://en.wikipedia.org/wiki/Wikipedia:Size_in_volumes. I think the estimate is for 1.9 million pages Also, there was another page along the lines of what you're thinking: https://en.wikipedia.org/wiki/Wikipedia:Terminal_Event_Management_Policy https://en.wikipedia.org/wiki/Wikipedia:Terminal_Event_Manag.... Although it was an April Fool's day joke, it does give some idea of what's involved.
- Houshalter 13y agoWell practically speaking you could just use images and then have the first book as a sort of pictionary with words and pictures that demonstrate them. Once they figure out enough words they can start to figure out other words that can't easily be explained by a single picture, and grammar can be worked out from there. Sort of like the Rosetta stone. But this is useless to the post-apocalyptic hunter gatherer, civilization would have to be reestablished by then. And hopefully they at least understand the idea of writing words on paper and don't just worship it as a religious thing. There has actually been work on doing that, attempting to mark radioactive waste dumps in a way even someone in a completely different culture from a distant future could understand. It's really interesting and there is pdf on it here: http://prod.sandia.gov/techlib/access-control.cgi/1992/921382.pdf http://prod.sandia.gov/techlib/access-control.cgi/1992/92138... If you are going to communicate with a completely alien civilization, that is one that can't even understand images, expressing information is even more difficult. My best guess is that you send a message with a really obvious pattern to it, then use that pattern as a basis for sending more information. For example, send a ton of examples of simple code in a simple programming language, and their output. They can figure out what it means. Then encode your messages in the programming language somehow. Send a simulation of 3 dimensional space and little objects in it interacting, for example.

- wrongc0ntinent 13y agoText-only versions, even straight from dumps, have had some bad formatting and truncation problems over the years, can't wait to try this. And here's a use case: https://news.ycombinator.com/item?id=6676661 https://news.ycombinator.com/item?id=6676661
- eksith 13y agoIt would be interesting if it keeps a version history between each dump file. WP often deletes articles that it finds not notable (these are excluded in dumps) and it would be nice to still retain the last version. In an odd way, we're going back to days where encyclopedias came in CDs. There was Encarta on a single disc, now we can have a lot more for around 80Gb ( http://xowa.sourceforge.net/requirements.html http://xowa.sourceforge.net/requirements.html )
- gnosygnu 13y agoThis is an interesting idea. When Wikimedia finalizes an incremental backup solution, it may be possible. They'll release a dump with incremental additions / updates / deletions. You would then have XOWA accept the additions / updates, but ignore all the deletions. It would place more responsibility on the user to maintain their copy of the dump though.
- eksith 13y agoThat's true. The burden then shifts to the user. But in a way, that's also good because then you can choose which snapshot to follow. It's a bit like maintaining your copy of an OS. You can stick to the "stable" branch or, if you're feeling adventurous, you can switch to "release". If you're really into the bleeding edge, you can go with the "nightly" build. All-in-all, I really like this. One concern I have is the possible increased bandwidth load for WP. Maybe you can include a small icon or notification to support it by donations. Couldn't hurt to have one there for yourself as well.
- gnosygnu 13y agoSource control is an interesting analogy. In the same vein, when a user syncs their version with the main branch, there will be hundreds of thousands of changes to review. It'll be pretty harrowing for anyone to figure out what to keep / reject. Just something to consider. Anyway, thanks for the food for thought as well as your suggestion. I added donation links for archive.org and wikipedia tonight.
- csmuk 13y agoThis makes me wonder why we couldn't have a DVCS with encyclopaedia content in it. That would be easy to "pull" offline and update regularly and "push" back up with changes. It'd be easier to distribute content and version it as well. Oh and patch queues could be used to review and edit content. A local HTTP service or desktop app, DVCS and indexer would do a fine job of this.
- arthulia 13y agoI think it's just not feasible/useful for most people. The latest copy of Wikipedia is 42GB, and that's not including images or earlier revisions.
- csmuk 13y agoTo be honest, a lot of wikipedia is crap. An abridged version would be a couple of gigabytes perhaps which isn't beyond the realm of possibility. That'd fit nicely on a smart phone/tablet and could be taken somewhere with less than adequate data connections (read most places on this planet).
- adrianN 13y agoGood luck with getting the editors to agree which parts are crap.
- qznc 13y agoYou can get the page view logs. You can filter out most of the garbage that way. http://dumps.wikimedia.org/other/pagecounts-raw/ http://dumps.wikimedia.org/other/pagecounts-raw/
- tommorris 13y agoJustin Bieber: 594,757 views in the last month. Origin of birds: 8,506 in the last month. Ogden L. Mills (secretary of the US Treasury under Herbert Hoover): 399 views in the last month. What is in the public interest is not the same as what the public show an interest in. Page views won't necessarily help you filter Wikipedia...
