Update/reset mediawiki password for a user directly in SQLite DB without SUDO (NFSN/ edge case)
// Replace <DB> with actual DB name
$db = new PDO("sqlite:/path/to/<DB>.sqlite") or die("cannot open the database");
// The WHERE clause excludes internal users; feel free to filter it any way you want
$query = $db->query("SELECT * FROM user WHERE user_email <> '';");
// Get the column names; unfortunately this is the simplest way
$meta = "";
for ($i=0; $i<=7; $i++) { $meta = $meta . "\n" . $query->getColumnMeta($i)["name"]; }

Create commits and send pull requests on GitHub from CLI with cURL


  • Personal Access <token> for <user> with all repo[...] access (may need more permissions, depending on the commit)
  • The <user> having write/push access to the existing <branch> of the intended <repo> of <org|user>
  • For creating new commits
    • The base64 encoded file content <base64content> is required.
    • To update an existing file, the <sha> hash of the file that's being replaced on GitHub repo is required

Creating Commits

Creating commits with /contents endpoint come with a limitation (as of APIv3) that it can only create/update a file. Updating multiple files (with a DIFF) doesn't seem to be possible very easily. The SHA sum is only required to update a single file with new contents, not for creating new file.

URL scheme customization for a Ghost blog

Quick steps to change URL scheme in a self-deployed Ghose blog:

  • Open DB in CLI: # sqlite3 content/data/ghost.db
  • Set the UX properties (optional): sqlite> .headers ON & sqlite> .mode column
  • Check the settings table (look for key "permalinks"): sqlite> SELECT * FROM settings;
  • Change the URL scheme: sqlite> update settings set value = '/:id/' where key = 'permalinks';
  • Quit database (sqlite> .quit) & restart ghost server

N.B: year, month, day, slug, id etc are valid keywords for configuring the URL (let me know if I've missed any).
Statutory Warning: if you're using different database, the steps are similar, but the commands will differ to achieve the same purpose. Also, I'm not to be blamed if you broke your thing while trying this out.
