  • mDNS, Rendezvous, Bonjour, ahavi

  • .htaccess and URL rewriting – URL rewriting I want to get my WordPress blog paths rewritten as always intended. Where can I acquire the needed competence?

  • extracting fields from a Jira “issue” (like a very nice and useful description)? how to get the markup source of the issue description?

    No, Jira does not let you read (“per se“) the markup source of an “issue” – that’s why I went this way in the first place  🙄 – using Jira’s REST API: a “…/rest/api/2/issue/…” URL – how to use jq for json-tidying jq . X.json > X.pretty.json – extract the structure tree of your […]

  • another nice JSON file: how to extract its structure using jq $ jq -c ‘path(..)|[.[]|tostring]|join(“/”)|”.”+.’ The idea is to use one of the output lines in order to access the respective field on your next jq command line: $ jq “.fields.description” X.json

  • Oracle SQL scripts: how to use a variable for the table name There is a “test table” and there is a “serious table” – use a variable name for the table(s) in question!

  • how can I create a copy of an Oracle table without copying the data? create table xyz_new as select * from xyz where rownum < 0; In Oracle SQL Developer use the menu-function (maybe right-click) on the table you want to operate on (i.e. that you want to copy), “Table“, “Copy…“, w/o checking “Include Data“.

  • emacs table-mode: why does a kill-ring-save on a (single) cell mark the (entire) buffer as “changed”?*table–cell-kill-ring-save.html – within tables kill-ring-save is actually remapped to *table–cell-kill-ring-save That “feature” (marking the buffer as changed) is terribly annoying!!! You try to copy (AKA kill-ring-save) text from a table, and from now on something “tells” you, you “changed” the table – but actually you did not. You may be tempted to […]

  • emacs table-mode – generate HTML from an emacs table

  • emacs table-mode, how to print, … Rendering an emacs table as HTML table, possible for further intermediate processing – like splitting … – quite useful! So far I have always printed an emacs table as fixed-font text document – sort of ugly, but still useful.

  • emacs: in table-mode, how do I change the face used for cells? I find it very useful and necessary to know immediately, that a table got recognised by emacs as such. Emacs shows it in colours then. With the default settings I find the background blue1 (together with foreground gray90) sometimes / often “far too heavy”, let’s say: a contrast far too exhausting for my eyes. Really! […]
