I am still working on this page (I thought I created it under my personal space).
But I don't see how it is fundamentally different from, say, the Mac Users Group page. I'd appreciate any feedback about to fix the page to be more encyclopedic.
Update to SPXXL?
I believe ScicomP has somehow evolved into SPXXL. See https://www.spxxl.org
The link the ScicomP in the article doesn't respond or redirect, so it takes some exploration to figure out that it is now SPXXL and to find information on upcoming conferences.
If someone concurs, the least that should be done is update the links. Other suggestions?
