&gt; And screencasts are the second most useless way of conveying technical material (the top one being podcasts). You can&#x27;t skim through the material, you can&#x27;t search it, you can&#x27;t copy-paste it, you can&#x27;t print its fragments, it&#x27;s inherently hard to navigate.<p>Transcripts with diagrams and code blocks solves this problem.
