I know this sounds trite and stupid, but I have a recurring fantasy of travelling back in time and using my modern knowledge to change history. My greatest [imagined] downfall has always been a lack of access to Wikipedia, and how to get around it. This solves my hypothetical problem perfectly.
It's much more interesting to try to actually learn enough about how things work that you could, theoretically, reconstruct some of them. Take gasoline, for example: could you work out how to refine oil by partial distillation? If you needed to measure the temperature, could you make a basic thermometer and calibrate it? Do you know how to make metals from ore? If you go back to before the bronze age, being able to mix copper and tin could be a big deal.
This is really fun stuff to learn about. Plus, this way you won't have to worry about battery life.
Time travel could be impossible, but the end of the world could be right around the corner. I’m not a doomsdayer, but I do think it’d be fun to contribute my brains to a survival group. Better than contributing them to a zombie’s maw, wouldn’t you say?
How far down the rabbit hole do we go, and how much of my irredeemable nerdiness am I willing to admit to?
If we're talking Z-Day, then the most economical solution seems to be either to buy and convert an old mine, or to grab an old nuclear silo. Either way, one could reasonably assume that a full, automated backup of Wikipedia and other helpful sites would be stored on local servers.
If you're not a member of the "I can buy Minuteman silos, whatever bro" club, then your currency is best spent on ammunition and the pre-determination of likely gathering points.
If, in the unlikely event that you're just a nerd putzing around on the Internet when you should be doing Real Work, you have access to none of these, then I suggest you move quickly towards a zombie-proof survival plan.
Learning to make charcoal in bulk or blow glass are valuable purely for entertainment: it's not likely to be useful to you, but you'll have fun doing it. On the other hand, this was also my motive for learning about things that later turned out to have really high expected utility, like the concept of "expected utility".
I've seen the TED presentation about this and there is one thing I particularly disliked: all the energy and effort spent molding the plastic enclosure. I think it wasn't faithful to the concept of "recreating civilization from basic premises" that appeals more to me.
Then I recommend Lester del Rey's novel Lest Darkness Should Fall. It's about someone from the 20th century who suddenly and inexplicably gets transported to ancient Rome, after a while he accepts he can't get back to his time and decides to do something worthwhile where he is: keep the middle ages from occurring.
me too! I've thought a lot about when would be good times to do great things and which paths would be easy and which would be hard. Unfortunately it usually ends up with me realizing that going back to 2004 and starting youtube would be the greatest reward per time and difficulty. :(
I'd prefer going back to '97 with $10MM and buying Apple stocks, then sitting on my ass. My reverie could possibly be interrupted by getting in on Google's IPO. I'd also offer to buy each viral video from the last decade before it went big for $1k, then pop ads on it and let the money roll in.
I'm almost inclined to get one to replace mine, whose screen went permanently dim at some point.
The code is open source, so you could theoretically use it with custom content that you adapt to their build formats. They also provide downloads for a bunch of other-language Wikipedias, as well as Wiktionary, Wikitravel, and Project Gutenberg. You can swap out the built-in microSD card (8GB?) for a much larger one and just put everything on it.
I've got one of these too, and really like it. We take it when traveling, so if we find ourselves at, say, a Civil War battlefield, we can look up the story behind it.
One might think that you'd just use the browser on your phone. But very frequently, places of interest are also places with no cellular coverage. Having this data offline is great.

I tried to do this. Bought a card just for the purpose, downloaded the GBs of torrents, and set up the card as they suggest (as best I could decipher). I was never able to get it to boot up with my substitute data card.
Again and again, this topic keeps coming up and the surprising truth is: paper is the answer. Don't discount it.
There was entire writeup about this (I think it was posted to HN) that I can no longer find and would be grateful if someone could point me at (my Google-Fu is failing me on this one) that of all the data storage mechanisms we have, paper is the one that we best know how to maintain and preserve. It's nowhere near as "bulky" as people make it out to be, and when done right and taken care of properly, can last centuries.
The other article I was referring to earlier pointed out the pitfalls with all the modern "wonders" of storage and how woefully inadequate they would be for attempting to preserve knowledge/data in the big picture. Namely interfaces, specs, requirements, readers, electricity, and all the other goodies that silently play their role in powering your USB stick or bluray disc.
Paper is a good answer. Unless civilization has collapsed, and libraries are burning. (They are burning - or rather, being closed down permanently, one after another, right now in the USA.) Paper is the answer, unless you are a refugee living in your car (should you still have gas) or running with what you can carry.
Paper is not the answer for a pauper with no room to call his own, nor for a factory hand living in a dormitory. There are many people alive right now for whom paper is already not the answer. But some of them could benefit from a Wikipedia "gameboy."
Yours or my paper library will carry knowledge into the ages quite well - until some vagrant burns it to warm himself in the wintertime. A piece of electronics, on the other hand - assuming we could make one that really lasts - could be passed down as an heirloom. And, should it begin to flicker out, the words could always be read off and set to paper.
The real technical challenge would be figuring out how to store 16GB of data reliably for that long, I would wager. You'd probably need to use some sort of optical storage that would be chemically stable over the time you expect it to keep.
I'm no expert in this domain, so I'm not sure what this would look like, or if there's already a way to do this in a small enough form factor to be feasible and relatively inexpensive.
Here is an idea for vandalism. Find the last non-bot, non-ip edit. Verify that this user has been on Wikipedia for a while, has a talk page with no vandalism warnings (again you'd have to check the history for the last edit made by someone other than the user), and/or has made more than 100 contributions. Won't get everything but should be effective.
Exactly. Whenever I read about one of these projects that are distributing Wikipedia content offline, my first thought is - How do they check all the content for vandalism? They most probably neither have the time nor the expertise. On the WP site, such things get detected and rolled back quickly and that is one of the reasons the whole thing works. Once you take that out, it is shaky territory.
They don't curate it at all, they just load snapshots.
In practice, it's no shakier than before. Whenever you load a Wikipedia page, there is a certain probability it's vandalized. I'd be surprised if the probability were going down, since as it is more widely used it attracts more trolls. If the probability is staying relatively constant, it doesn't matter if you are looking at the current data or a snapshot from six months ago, the probability of a random page being in a vandalized state is about the same. And of course, if the vandalized page rate is going up, a snapshot would be better than the live site.
You could argue that, if you discover a vandalized page, you can't do anything about it on the Wikireader. You could argue that once you find a vandalized page, it's going to stay vandalized until you load another snapshot. But those are consequences of the tradeoff for the size and network independence of the device.
You are right when considering an individual. When you consider a group of people, the probability that all of them saw the vandalized version on Wikipedia site goes down as the number of people increase. With the offline version, it stays the same.
If you consider the case of disadvantaged children whom some of these projects aim to reach, the whole peer group now has the same vandalized information and there may not be a secondary source of information.
Gameboy pockets seem to run around $20. They seem almost perfect for this sort of thing. They can run on two tripple-A batteries continuously for 10 hours. And since they boot instantly and actually turn off when you tell them to, under normal usage that will last you weeks. The screen resolution could be better but for reading short articles it's good enough.
And when you take the wikipedia cartridge out, you have a gameboy.
I wonder how much it would cost to make a Wikipedia gameboy cartridge?
The cartridge interface is general-purpose, so you can stick whatever electronics you like in the cartridge. If I was producing these at scale I'd burn into an asic the compressed data, the decompression logic, and some paging/addressing logic. So you say "give me article 1234" to the cart and it streams you the decompressed article. You could do that with an fpga if you were making them in low volume.
For an example of the crazy things you can do with gameboy cartridges look at Gameboy Camera.
Based on this (see: 1saleaday), this item got excessed/liquidated by a distributor last... fall probably. Judging by the low ratings/views on Slickdeals most people just aren't interested in such a device, even at $20/pc. Several players (maker/distributor/liquidator) probably took losses unless they were on consignment.
Judging from the initial response on HN, this item totally could've been remarketed better. :)
Just trying to share some experience here since I used to do retail pricing analytics. The $15 prices will come back, if not lower (though perhaps through alternate offline discount-store channels).
If you look at how the price continues to fall after October through Christmas shopping season by one inventory holder (1saleaday, probably has 10k+ pieces to liquidate) and how poorly the deal has been moving even with guerilla marketing (see: views on each thread, as well as thumbs-up)... all I'm saying is that this deal's been a dog in retail.
While Kindle touch won't run a year on AAA batteries, it's not that far away of it. Based on my calculations I'd guesstimate that Kindle should run at least a month with 2xAAA batteries (assuming same "multiplier" that WikiReader uses, 90 hours = 1 year => 10 hours = 1 month). I'd argue that it's good enough.
I think they were posting from the opposite side of things, more "Given a $100 device that runs for a year on one set of AAA batteries; why not put Wikipedia and Project Gutenberg books and OpenCourseware and everything else possible on it."
this looks awesome and what not, but i feel the screen itself is my biggest gripe. i'm only judging this based on the pictures on amazon, so it could look better in person. the screen makes it look like a device you would have found in the 90's :\
What it really looks like is one of the shitty "handheld videogames" your dick uncle gave you for Christmas instead of a GameBoy game. You know the ones, with predefined sprites in predefined positions that would sort of move around with the eventual refresh? The kind your Casio calculator outperformed? The kind you could find in the dollar stor for $6?
I love the idea, but I'm with you on the screen. I'd be willing to shell out more for something Kindle-like.
