amen zwa, esq.<p>Earlier this week, I was invited to give an talk on image processing techniques to a small group of senior-level engineers who work in a "certain sector". When I opened up the floor for questions, one audience member immediately shot a question at me. I shushed him, and whispered, "Not here man. Reach me on <a href="https://mathstodon.xyz/tags/Signal" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Signal</span></a>." The small room erupted.</p><p>OK, that was not at all original and a low-blow at best. But that still gave me a certain amount of satisfaction.</p><p>Such little <a href="https://mathstodon.xyz/tags/digs" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>digs</span></a> are good for this underdog's soul. The underpaid archaeologists might well be the most contented people.</p>
