Refactoring databases with sqlite-utils extract
Yesterday I described the new sqlite-utils transform mechanism for applying SQLite table transformations that go beyond those supported by ALTER TABLE.

[... 1461 words]Render Markdown tool (via) I wrote a quick JavaScript tool for rendering Markdown via the GitHub Markdown API—which includes all of their clever extensions like tables and syntax highlighting—and then stripping out some extraneous HTML to give me back the format I like using for my blog posts. # 3rd September 2020, 12:08 am
