<p>SRECon was amazing! The talk line-up was mind-blowing, and it was great to meet many of you there. A big thanks to all the speakers for making this one a conference to remember.</p>

<div class="sreweekly-description">
<p>Last week was only the second SRECon I&#8217;ve managed to attend. Rather than post raw notes from all the talks I attended, I tried something different: I only wrote down the really big stuff that made me think or blew my mind. I&#8217;m hoping that just reading this might give those of you that weren&#8217;t able to attend a taste of the conference.</p>

<p>Inspired by SRECon, John Allspaw posted this Twitter thread on the &#8220;Humans Are Better At&#8221; / &#8220;Machines Are Better At&#8221; concept.</p>
<blockquote><p>Who will argue with &#8220;make the computers do the easy/tedious stuff so humans can do the difficult/interesting stuff&#8221;? (apparently, I will)</p></blockquote>

<div class="sreweekly-description">
<p>This article goes into what the pilots of the Lion Air 737 Max 8 (and presumably the Ethiopian Airlines one as well) would have had to do in order to regain control over the aircraft. We&#8217;re starting to get hints of the task saturation and alert overload both sets of pilots may have faced as they tried to handle the situation:</p>
<blockquote><p>The Lion Air crew would have had to accomplish this while dealing with a host of alerts, including differences in other sensor data between the pilot and co-pilot positions that made it unclear what the aircraft’s altitude was.</p></blockquote>
