Hey, did you know we have a Wikipedia page? We didn’t either. Until today you could search for “Hackaday” and nothing would come up. That’s because it’s listed as “Hack a Day” and it hadn’t seen any TLC in at least a couple of years.
Here’s the great thing about Wikipedia, they want factual information so they discourage people with Conflicts of Interest from editing the pages. That means that having the Hackaday Staff edit the page is a sticky issue. I did indeed edit the page in order to add more sections (History, Hackaday Projects, Accolades) to make it easier for the community to work on the article. I disclosed this in the “Talk” section, requested the logo be uploaded, and began a discussion suggesting the page be moved.
Ethically this is about all I think we should do. It’s up to you now. We’d love to see a well-written, immaculately cited Wikipedia article for this great thing we’re all involved in.
It is my pleasure to welcome two new members of the Hackaday team. [Kevin Darrah] and [Kristina Panos] both have electronics backgrounds, and following in the tradition of the entire team they are long-time readers of Hackaday. Both are already hard at work. You can learn a bit more about them on the Staff Page.
While I have your attention the writers, editors and I would like to thank our parent company. We frequently refer to them as the “Evil Overlords” (actually, they started it!) but it’s turning out to be a really great relationship. I asked them to make a donation to Wikipedia in Hackaday’s name and they were happy to do so. Not only do we often link to Wikipedia in our articles, our writers use it constantly when researching for posts. Thanks SupplyFrame!
One part inexpensive uC, one part touch-screen, one part Internet knowledge-base all come together to make up this Wikipedia reader. It functions in a very similar way to commercial versions by parsing XML dumps from the popular website to an SD card for use on the device. This is not limited to Wikipedia, but could just as easily be an e-reader. [Rossum] developed the package using an NXP ARM Cortex M0 model LCP1114 microcontroller. They cost just a couple of bucks but pack a 50 MHz punch with 32 KB of program memory and 8 KB of SRAM. If the nanotouch and the AVR iPhone concept didn’t convince you that [Rossum] knows what he’s doing, the video after the break of this newest creation will seal the deal.

OpenMoko, the company behind the FreeRunner open-source phone, released their latest product today: WikiReader. It’s a small mobile device for browsing Wikipedia. Rather than use a wireless network to pull data off of the web, it has local copy of the database on a 8GB microSD card. This approach has been used before, and it lets the WikiReader be compact and really cheap. It uses a Kindle-esque touch-screen display that allows it to run on 3 AAA’s for about a year. The device itself costs just $99, but you can choose to receive updates by snail mail for just $29/year. Alternatively, you can just download the +4GB file and dump it on the card.
Like the FreeRunner, this project is also open-source. The code isn’t available yet, but they say it will be released soon. With luck, the device will be really easy to hack.
This project is particularly amusing. It doesn’t have a whole lot of practical use, but it makes up for it in style. They have an SD card with Wikipedia from 2003 downloaded to it. This is accessed with a Parallax propeller microcontroller based system and displayed on a small retro looking screen. We like it. We don’t think we would ever actually use it, but we would definitely keep it around.
Wikiwatcher has just officially released their new tools. We covered their announcement at The Last HOPE just last month. The 2.0 version of Wikiscanner is not ready just yet.
Poor Man’s Checkuser exposes the IPs of quite a few user accounts. There is a wealth of data here which can be used as a base for your own tools. Potential Sockpuppetry is a good example of using this data; it shows what IPs are associated with multiple accounts and could be run by the same person. It takes data from the Poor Man’s Checkuser and arranges it by organization and IP range. Beaver Scope keeps an eye on edits coming out of all specific locations on MIT campus. The author used this list of MIT IPs to monitor MIT’s activity during the Caltech-MIT pranking season. It is able to pinpoint exactly which building an article is being edited from. The team hopes to see people develop new tools from the Poor Man’s Checkuser data.
[Virgil] presented the next version of Wikiscanner at The Last HOPE today. To build the original Wikiscanner, he scanned the monthly database dump of anonymous edits and compared that against a purchased list of known company IP addresses. The 34.5 million edits account for nearly 21% of all edits. The idea was to unearth businesses and groups white washing critical pages. This only handles anonymous edits though. Users could log in to avoid having their IP reversed.
In the new version, [Virgil]’s team developed a Poor Man’s CheckUser. If you spend too much time editing a talk page, your session could end and when you hit save it attaches your IP. Most regular users will then log in and remove their IP. They found 13,000 username/IP address pairs by searching for IPs being removed and replaced with usernames. These are some of the most active users. Using this list, they could potentially uncover sockpuppets or potential collusion by top editors.
