(Edit this sect.0)

See Things to do on the OEIS for suggestions on how you can contribute right now to improve the main http://OEIS.org.

This page is about suggested improvements on the OEIS wiki, mainly for server admins/sysops. As such there is much overlap with the Suggested Projects page cited below.

See also: Future Projects and Suggested Projects. [TO DO: clarify what should go where, and (re)organize the "TO DO"s.]

(An attempt to do so has been made through the page To do featuring a list of to-do lists, and the new Category:To-do lists.)

Known problems

  • When hovering over the link to a sequence, the pop-up text should show the sequence definition (the %N line).
    this would have required significant changes in the mediawiki software. It's one of may reasons we eventually abandoned mediawiki for sequence data. David Applegate 01:04, 18 November 2010 (UTC)
    I don't understand, since it is available on mediawiki, e.g. as Navigation popups. Without this, the index in its current form is sometimes totally useless, look e.g. at http://oeis.org/wiki/Index_to_OEIS:_Section_De:
decimal expansion , sequences related to :
   decimal expansion contains no 0's: A007377, A007496 
   decimal expansion of square roots: see under: square root(s) 
   decimal expansions (1):: A002117, A007493, A002163, A002392, A007377, A007496, A005532, A006891,(...)
   decimal expansions (2):: A005533, A005600, A005596, A006834, A005534, A002193, A002285, A002581,(...)
   decimal expansions (3):: A001620, A005480, A007450, A001622, A005597, A003676, A002162, A005481,(...)
   decimal expansions (4):: A006833, A003675, A005482, A006752, A002391, A002388
   decimal expansions - see also under individual constants (e, A001113; Pi, A000796; etc.) 
Can you see what I mean? The list of sequences (although not even 0.1% of the "cons" sequences) does not give any hint on what you find when you click - a link like http://oeis.org/search?q=keyword:cons&fmt=short would be at least as helpful. — M. F. Hasler 03:35, 26 October 2011 (UTC)
  • Doing this client-side would put serious load on the servers, if it means that each view of the index will generate hundreds of HTTP requests for the individual sequences. At least this could be cached if done server-side. I agree that this would be nice, and is probably worthwhile despite the difficulty. Charles R Greathouse IV 21:46, 26 October 2011 (UTC)
    Could be done manually (although not practical) like this: A000040 (manually done with the {{abbr}} template, e.g. {{abbr|The prime numbers.|A000040}}) — Daniel Forgues 18:16, 28 October 2011 (UTC)
    Concerning server load: On wikipedia with millions of users this works fine, although that "popup" even loads pictures. I think a direct access to the internal format, e.g. http://oeis.org/A006882/internal or http://oeis.org/search?q=id:A006882&fmt=text it would not create so much load. Implementing another access to that info (e.g. http://oeis.org/A006882/name which would just send back the name, taken from a dedicated & optimized database) could be another solution to this. But a bot implementing Daniel's solution above would just be fine. — M. F. Hasler 00:36, 18 January 2012 (UTC)
  • File and image uploading often fails.
  • The page http://oeis.org/A000045/a000045.html is linked with the diagram a000045h.gif which does not show up. Peter Luschny 10:46, 5 January 2012 (UTC)

Future changes

  • fix other html->wiki pages
  • post-edit syntax checks
  • new sequence page template
  • updates from wiki -> cat25
  • updates from wiki -> ADATA
  • perhaps: adjust review label (Readability -> Quality?)
  • check reviewed/unreviewed look for non-editors
  • tune reviewing process
  • pdf, pdfbook
  • a new-user guide. Among other things, point out that user preferences allow selection of the local timezone. The server time and wiki default are GMT.
  • perhaps: handle classic/listen/plot/table links in skin instead of template
  • system backups. (Assuming that this is certainly ("automatically") implemented (at least by the web hosting company), some information would be welcome.)

known missing pages

Completed

  • users are not allowed to edit or create pages, including their own user pages. This needs to be changed to allow editing of pages other than those derived from the classic OEIS
    • 19:58, 30 October 2009 (UTC) fixed
  • categories whose name includes |{}[]<> are broken
    • 19:58, 30 October 2009 (UTC) worked around, by converting {}[] to ()() and |<> into unicode characters which are visually similar. The restriction that page names cannot contain |{}[]<> is quite fundamental to the mediawiki software.
  • the search engine needs significant tuning - A005132 works, but A5132 doesn't. Also, searching for sequences (for example, "2, 3, 5, 7, 11") doesn't work.
  • Some lines which begin with a sequence number don't become links. See A139827 for an example.
  • perhaps: make show preview mandatory
  • lucene search data updates
    • David Applegate 19:01, 8 November 2009 (UTC) implemented; generated updated index snapshots in lucene is fairly cpu-intensive, so need to think about how often to run.
