[Jgeneral] Report of the J Wiki Meeting of December 7, 2023
== Report of Meeting 2023-12-07 == Present: Ed Gottsman, Raul Miller, and Bob Therriault Full transcripts of this meeting are now available on the its wiki page. https://code.jsoftware.com/wiki/Wiki/Report_of_Meeting_2023-12-07 1) Ed reported that he can now get Skip Cave's answers to Quora in plain text. There is still work to integrate the text into the J Viewer. Ed asked if the time slider for forum posts was used by anyone. Dropping the time slider would free up real estate. Raul said he does not use it. Bob said that he does use to get a full range of forum posts, which is the opposite way of what Ed was expecting. Ed feels that there is ample opportunity to specify the search enough to get most of the hits you want within the 200 that are returned. Ed mentioned that you can also choose the sources that you are searching. Bob feels it is important to let people know that they are getting up to 200 of the possible matches, but that there may be further hits that they are not seeing until they further refine the search. There is also a dropdown that can narrow down the results to a particular forum. Ed will work on the documentation that may be needed by the user to take full advantage of the J Viewer. Ed thought he might try tooltips to guide the user. 2) Ed is still exploring solutions for highlighting in night shift mode. Bob suggested just using the same colored background that might work in either mode. Green would be a neutral option. As another option, increasing the border style might make the action required more obvious. Ed has activated two finger scrolling on Raul's suggestion and it works better. Ed has included the old Vocabulary into the search with the proviso that NuVoc is the current documentation. Bob mentioned that he does often use the Vocabulary for information on Foreign Conjunctions. The search fields labels are now "In order" and "Any order" to make the search word options more evident. 3) Ed is thinking about future enhancements to the Viewer that might include looking at code in which case Dissect https://code.jsoftware.com/wiki/Vocabulary/Dissect would be an interesting addition. If looking at nouns then Jig https://code.jsoftware.com/wiki/Addons/debug/jig might be an add-on to include. Ed asked about the limitations of showing large nouns. Bob said that the views of numbers extends into multiple thousands of elements. Character views may be a little more challenging because each character carries more svg code. Ed wondered about ways to show higher dimensions. Bob said he had patterned his view on the text view with extra blank lines between the dimension breaks. Ed was considering specifying planes and then moving through the planes in three dimensions. Then a discussion on visualizing higher dimensions followed. Ed's goal is to be able to be ready to present viewing options that would be easily available to users of the J Viewer. This may include searching of Locales and Global nouns to provide quick access to information. 4) Bob wondered if there would be a way to have JHS from AWS shown in the J Viewer, possibly using the space for currently used for navigation or display lists of forum posts. This would result in having JHS next to the wiki page to allow experimentation. Ed wondered if since we are in JQt that we might incorporate something like the terminal to allow access to J. (Editors Note: since J is already running in the console then JHS would be able to access the J engine and display within the J Viewer). This would allow cutting and pasting from the wiki page into the J IDE. 5) Bob showed the progress that he had made on the Home https://code.jsoftware.com/wiki/Category:Home and Newcomers https://code.jsoftware.com/wiki/Category:Newcomers_N pages and the removal of the list of bottom links and instead display those links with a category tree display of the links to the side of the content. In the case of Newcomers Essays https://code.jsoftware.com/wiki/Category:Essays_and_Articles_N.7 this allows the body to be an annotated list with a sidebar of a category tree. This is even more useful in Reference https://code.jsoftware.com/wiki/Category:Reference_R where there is a lot of information. Ed asked if the subtree would be shown on the target page accessed from the category page. Bob said it would not because a page might be in a number of categories and you would need to know which category you had arrived from. Bob felt extending the categorization might make this less of an issue. There are 200 element limits to the category tree display and this becomes an issue for pages like NuVoc. Bob will recategorize the large numbers of pages into sub categories. NuVoc's category page https://code.jsoftware.com/wiki/Category:NuVoc_R.1 would be Primitives https://code.jsoftware.com/wiki/Category:Primitives_R.1.1, Foreign Conjunctions
Re: [Jgeneral] https certificate problem, forums.jsoftware.com
Looks like a transient error. The page forums.jsoftware.com just forwards to the System/Forums page on the wiki. I don't see any errors now when I load that page.

Re: [Jgeneral] crash
Fixed for the release. Thanks for taking the time to report it.
The problem was in the special code for (atom { list), which reuses the
x argument block for the result when possible to save an allocation. It
went too far, by reusing x even when y is boxed. This works much of the
time but not when executed under &.> .

[Jgeneral] https certificate problem, forums.jsoftware.com
I'm getting NET::ERR_CERT_COMMON_NAME_INVALID from forums.jsoftware.com which causes my browser to issue a warning that someone could be trying to hijack the site. Apparently, its certificate is for www.jsoftware.com This probably means that the apache VirtualHost block for forums.jsoftware.com is missing one or more statements: SSLCertificateFile, SSLCertificateKeyFile, SSLCertificateChainFile Though possibly there's some other problem with these files or these statements. Thanks, -- Raul -- For information about J forums see http://www.jsoftware.com/forums.htm
