OLPC:Wiki

This is a wiki page about this editable site. We are currently running MediaWiki Version 1.15.2. If you are new to wikis, please read the Wiki getting started page for tips, tutorials, and people who can help you get going. Experienced wiki users, see our Style guide for how you can make your edits more helpful and efficient.

For cross-population of the wiki with updates from RT, trac and the like, see OLPC:Wiki integration.

Please leave notes about your wiki experiences, and comments or suggestions about this wiki, here. For more on children using wikis, see wikis for children. For more about wikis, see Ward Cunningham's lovely rundown of the principles he followed when developing the first wiki.

skins

The default skin has been changed to Shikiwiki. Common skins available are listed below:

Shikiwiki

This is a monobook clone developed by Simon Dorner, Helga Schmidt, daja77, and Sj.

bugs and requests

• A better-colored XO-icon for the user-login, along the top-right nav. The colors of the current one are a little bit off.
• IE issues
  • The current layout breaks on certain pages in IE. For instance, when inside a pop-up window... (noticed when testing the new contributors-program database; see user:aaronk for details). Bug reporting and IE testing are appreciated.
  • The top tabs are transparent in IE; not intended.
• The "translate" form dropdown is rounded in Safari, and looks out of place.
• There is little in the way of hovertext, and a number of images lack alt tags.
• Alignment of the namespace tab ('article', 'project' et al) is slightly imperfect; at some text-sizes it doesn't align with the body border.

Monobook

Monobook remains the default mediawiki skin, is close to shikiwiki, and the most robust of the other available skins.

Next up: adding a patch to the extension so that it knows how to find the revision # of the document it's transcluding. Sj talk

The CSS for this extension is inappropriate; we should tuck the 'Welcome to gitembed' header beneath the main display rather than to the left of it. --Michael Stone 18:24, 4 June 2008 (EDT)

Suggestions and comments

Losing summaries

I find that when I edit pages and add links, the process of asking me an arithmetic question frequently discards the summary that I entered, so I have to scroll down and enter it again. I haven't been able to determine a pattern to when this happens.--Mokurai

Does it ask you an arithmetic question when you are logged in? It is only supposed to ask when the edits are anonymous (part of the Mediawiki anti-spam measures). --Walter 08:25, 22 October 2006 (EDT)

I get the arithmetic question when I add external links, even when I am logged in.--Mokurai 19:56, 4 November 2006 (EST)

I get that too even if i'm logged in --EdX 13:45, 16 March 2007 (EDT)

I get it too when logged in, but only if I add a link to the page. --ixo 07:54, 29 December 2007 (EST)

Better CAPTCHA

As everyone knows, a text based captcha is insecure. In the case of this wiki, it is also annoying. Thus the solution: reCAPTCHA. Not only does it have an audio alternative, but it also helps digitize books. ffm 12:50, 1 January 2008 (EST)

Searching for "FORTH"

The Wiki Search function does not find the word "forth" on any page or page title. The Go function correctly goes to the page entitled "FORTH". My problem is that I have to use Google to search for references to the FORTH programming language in order to make them into links, now that I have created a FORTH page.

forth site:wiki.laptop.org

--Mokurai 01:55, 22 October 2006 (EDT)

The wiki is currently using a mysql hack, rather than a real text search eingine. No stemming, etc. See #2162. Volunteer needed. In the meantime, the best bet is to use google, as linked from wiki's search results page. MitchellNCharity 21:39, 28 August 2007 (EDT)

Make wiki Search CasE INsensitive

We will all be better served if both Go and Search are not sensitive to case. Google works that way, so practically every participant here will be LESS surprised if case is ignored. How can this objective be pursued? Nitpicker 19:06, 9 December 2006 (EST)
