My primary computing and web browsing device remains my laptop, with Emacs and Firefox being my main tools. One thing that does manage to distract me sometimes is YouTube recommendations. As a result I have written a little userscript for myself to disable shorts and recommendations: https://github.com/susam/userscripts/blob/main/js/ytx.user.j...
So far the userscript has been successful. As a side effect of disabling the recommendations sidebar, the video panel expands to occupy a larger part of the screen which I quite like. Here is a screenshot: https://susam.github.io/blob/img/userscripts/ytx.png
Also, I still depend heavily on physical textbooks, a rollerball pen and a stack of plain A4 paper for most of my learning and exploration activities. This routine has helped me to stay away from modern attention media too.
