<p>The SRE book has a chapter covering on-call, but it&#8217;s best suited for huge-scale companies. What should the rest of us do?</p>

<div class="sreweekly-description">
<p>If you&#8217;re feeling hesitant about chaos engineering, or you&#8217;re trying to convince someone who is, this might be useful. The myths are:</p>
<blockquote><p>Myth #1: Chaos engineering is testing in production<br />
Myth #2: Chaos engineering is about randomly breaking things<br />
Myth #3: Chaos engineering is only for large, modern distributed systems<br />
Myth #4: We don’t need more chaos – we already have plenty!<br />
Myth #5: Chaos engineering is only for very mature teams/products</p></blockquote>

<div class="sreweekly-description">
<p>Drawing parallels to the high modernism movement during the cold war, this article raises interesting questions about the direction SRE is going, and system administration in general.</p>

<p>Riffing off of a tweet by Charity Majors, this article explores the idea that moving faster can actually be safer, despite an urge one may feel to slow down.</p>

<div class="sreweekly-description">
<p>An extreme oversimplification of this incident would be: multiple engine failure on a plane subsequent to a maintenance error on all engines. This accident is <a href="https://www.boeing.com/commercial/aeromagazine/aero_05/textonly/m02txt.html">cited</a> as a reason to have separate mechanics work on each engine, in hopes of avoiding duplicated errors.</p>

<div class="sreweekly-description">
<p>This one blew my mind. By recording instruction execution traces in a ring buffer, they&#8217;re able to reconstruct enough information to step through the execution leading up to a crash — even though they weren&#8217;t running the application under a debugger!</p>

<p>Automation is supposed to take some of the load off of the human operator, right? But in reality, humans need to build a mental model of what the automation is doing in order to use it safely and effectively.</p>
