Note that this is the “raw” log — to put it in context and make sense of the abbreviations, you need to read the <i>actual</i> paper named <i>The Errors of TeX</i> (1989, also reprinted in the book <i>Literate Programming</i>). The paper has DOI 10.1002/spe.4380190702 and Google search finds a copy here: <a href="https://yurichev.com/mirrors/knuth1989.pdf" rel="nofollow">https://yurichev.com/mirrors/knuth1989.pdf</a><p>At minimum, the abbreviations are also given in <a href="https://www.tug.org/TUGboat/tb10-4/tb26knut.pdf" rel="nofollow">https://www.tug.org/TUGboat/tb10-4/tb26knut.pdf</a> but the paper is much more. (Rehashing my comment from earlier: <a href="https://news.ycombinator.com/item?id=18177962" rel="nofollow">https://news.ycombinator.com/item?id=18177962</a>)<p>Incidentally, some archives of the old TeX source code are available online... it might be an interesting project to combine the two, but I'm not finding the time to do it. If anyone is interested in helping / doing it, let me know. :-)
Here's the entry for 14 March 1978:<p>> Came in evening after sleeping most of day, to get computer at better time.<p>> Some day we will have personal computers and will live more normally.
In case you didn't know, the source code of TeX itself is Pascal and published as a 500 pages literate programming tool which clearly is rendered with TeX, available at <a href="http://texdoc.net/texmf-dist/doc/generic/knuth/tex/tex.pdf#625" rel="nofollow">http://texdoc.net/texmf-dist/doc/generic/knuth/tex/tex.pdf#6...</a><p>If this was machine readable, then TeX could compile TeX ;-)
