In 2011 editing existing sequences was far simpler than it used to be in 2001 based on the tricky internal format: Find the sequence, log in with your OeisWiki account, click edit, update say a broken link, optionally add an edit comment, click submit, and some minutes later I got an e-mail that the proposed modification was approved by an associate editor. Actually I found the how to after the fact.

Fun stuff

Three punched cards (3*80 columns) minus a space in column 72 (3*1), the vital card serial numbers in columns 73..80 (3*8) for a re-sort if you ever drop the deck, minus the internal format columns %S, %T, %U followed by a space (3*3) yields 204, or roughly 200 columns for comma separated terms if they happen to fit nicely in the remaining 3*68 columns.

In 2012 an editor changed it to 260 including spaces, five years before RFC 8140 was published. The OEIS corrupted the IETF. Joke off, I didn't submit a sequence for over a decade, and in 2017 I wasted 60 columns for more terms in A293308.

Known OEISwiki issues

On Very Important Pages including the Index to OEIS, the Works Citing OEIS, the Style Sheet, etc. the review process—shown as a green quality revision line on Special:Contributions without a pending revision link on the Special:Watchlist—is typically very fast. On OEIS proper the review of uncontroversial proposals, e.g., a new Numberphile video link, can be also very fast, almost daily.

The review of other proposals on OEIS proper, not limited to new sequences, can take weeks, depending on the discussions with the Editors. One of the 134 editors has to grok and check the proposal, tagging it as reviewed when all nits are fixed. After that step the final approval (publication) by one of the 44 reviewers is again very fast.

The MediaWiki terms editor vs. reviewer correspond to the OEIS terms Associate Editor and Editor-in-Chief, respectively. The review of other OEIS Wiki pages can take years, and clearly that is not as it should be.

Technical issues

• The list of supported media types for Special:Upload does not yet include any video type, notably Ogg Video and WebM (VP9 or AV1 video with Vorbis or Opus audio) are not supported. JFTR, the upload size limit is 2 MB. The supported MIME types include text/plain with file extension .txt, e.g., File:rxshell.rex.txt for rxshell.rex.
• Instant commons is a mechanism introduced in 2011 permitting MediaWiki projects to import resources from WikiMedia commons. It is documented on the MediaWiki wiki. If you see a red link instead of an image from WikiMedia Commons below it is not (yet) installed here, or somebody copied it manually, as I did for File:By-nc.svg:

  File:CC-BY-SA icon.svg

• For huge images the thumbnail generator fails miserably. The limit is width × height < 12,500,000 pixels, e.g., 3536 × 3535 = 12,499,760, but 3536 × 3536 = 12,503,296.
• Wikidata is a pure WikiMedia project, unlike Instant commons, and this wiki needs no d: interwiki prefix for plain links to Wikidata. But Property:P829 (en: OEIS ID) is interesting.
• Syntax highlighting with <source lang="matlab"> is not yet installed: <source lang="rexx">numeric digits 500; say digits()</source>
• The CC-BY-NC license used here is incompatible with the commons CC-BY-SA limits — whatever that means (IANAL), see my commons page hosted by Google.
• 

  CreativeCommons BY-NC
  The short version of the OEIS movie available on YouTube cannot be embedded on OeisWiki pages, because
  1. I got no permission to upload it as .ogv to commons due to the license incompatibility (see above),
  2. without InstantCommons that would anyway not help here (see above), but might be nice on Wikipedia(s),
  3. it also cannot be uploaded here — the 998KB are okay, but video MIME types are not allowed (see above),
  4. the short version apparently does not yet exist on the OEIS proper (the pages above the OEIS wiki), and…
  5. …even if it existed on OEIS proper the OEIS wiki would treat it like any external  file and refuse to embed it.
• As of February 2020 the oldest secure legacy LTS MediaWiki version was 1.31.6 (December 2019), anything older is insecure. The next LTS version 1.35 is planned for June 2020, the old LTS 1.31 is supported until June 2021. This Wiki is at version 1.30.0.
