I recently needed to convert some Apple Lossless music files to FLAC. Here’s how to do it:

And that’s it - it will convert all the .m4a files in that folder to .flac files, preserving the metadata. You can now delete the .m4a files if you want:

$ rm ./*.m4a

The compose key on Linux is incredibly useful, but not configured by default - and on XFCE there’s currently no graphical UI to change it. However, it’s pretty simple to change…​ here’s how to make the Caps Lock key your compose key:

That site has been up, looking mostly like that, for ~15 years - with zero maintenance or downtime. Nice to know it’s still valid CSS 1.0 :)

When I created that site originally, the options were either Adobe PageMill, or hand editing HTML in a text editor. I’ve never been a fan of WYSIWYG (what-you-see-is(supposedly)-what-you-get) editors - and the early ones were…​ not good, so I wrote all the HTML code by hand.

That site also has some data heavy pages, which are manually published from …
