Recording the links here for posterity:&lt;p&gt;• &amp;quot;Donald Knuth lectures&amp;quot; &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;playlist?list=PL94E35692EB9D36F3&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;playlist?list=PL94E35692EB9D36F3&lt;/a&gt; (111 videos)&lt;p&gt;This includes several sub-series but the playlists don&amp;#x27;t have the videos in the right order:&lt;p&gt;• “Aha sessions”: &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;playlist?list=PLoROMvodv4rNbeodV7vqxxxWpe4s_SFty&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;playlist?list=PLoROMvodv4rNbeodV7vqx...&lt;/a&gt; (Knuth used to run a “problem-solving seminar” at Stanford; these are videos from one such year.)&lt;p&gt;Three lecture series on TeX that are now of historical interest (e.g. the TeX program has changed considerably):&lt;p&gt;• “TeX for Beginners” &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;playlist?list=PLoROMvodv4rN1PKcXvzjor-Bl6o6eSNTN&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;playlist?list=PLoROMvodv4rN1PKcXvzjo...&lt;/a&gt;&lt;p&gt;• “Advanced TeXarcana” &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;playlist?list=PLoROMvodv4rNrDaAftaqMRQEmsARSpLHi&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;playlist?list=PLoROMvodv4rNrDaAftaqM...&lt;/a&gt;&lt;p&gt;• “The Internal Details of TeX82” &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;playlist?list=PLoROMvodv4rM2JuHk3qBhQDxY9QGrLrYE&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;playlist?list=PLoROMvodv4rM2JuHk3qBh...&lt;/a&gt; (I&amp;#x27;ve found this invaluable as I try to read the TeX program)&lt;p&gt;The following two playlists are still unlisted and I no longer know how to get to them:&lt;p&gt;• Mathematical Writing &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;playlist?list=PLoROMvodv4rOrFl78-o6m_QbJqTXGfVVb&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;playlist?list=PLoROMvodv4rOrFl78-o6m...&lt;/a&gt;&lt;p&gt;• Computer Musings - Donald Knuth &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;playlist?list=PLoROMvodv4rNMsVRnSJ44WuwbminUqXX2&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;playlist?list=PLoROMvodv4rNMsVRnSJ44...&lt;/a&gt;&lt;p&gt;(I happened to have them in my browser history… these playlists used to be linked from &lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;scpd.stanford.edu&amp;#x2F;knuth&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;scpd.stanford.edu&amp;#x2F;knuth&amp;#x2F;&lt;/a&gt; but as of yesterday they seem to have changed it up, and also made the videos public (why were they “unlisted” earlier? No idea).)&lt;p&gt;And completely unrelated, but if you happen to be interested in church organ music and the Bible&amp;#x27;s Book of Revelation, the world premiere of Knuth&amp;#x27;s &lt;i&gt;Fantasia Apocalyptica&lt;/i&gt; (&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;cs.stanford.edu&amp;#x2F;~knuth&amp;#x2F;fant.html&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;cs.stanford.edu&amp;#x2F;~knuth&amp;#x2F;fant.html&lt;/a&gt;):&lt;p&gt;• &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;playlist?list=PLvixIGKr5sJffdfwecygYqhXsgz-EBCC8&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;playlist?list=PLvixIGKr5sJffdfwecygY...&lt;/a&gt;</text><parent_chain></parent_chain></comment><story><title>Donald Knuth – The Joy of Asymptotics (2000) [video]</title><url>https://www.youtube.com/watch?v=U2W1y0a7PhU</url></story>
