For example, I&#39;ve often leaned on some of that when tackling something like the Raft project.</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.gamedev.place/@lesley" class="u-url mention">@<span>lesley</span></a></span> People definitely have a lot of takes on SICP, but I think the book is just as relevant as it ever was if approached from a certain perspective.</p><p>To me, the main value of SICP is in systems thinking. Right from the start, you&#39;re thrown into this very unfamiliar &quot;system&quot; and you have to start making sense of it. The book then employs various strategies of problem solving and thinking to do just that. I think there&#39;s a lot of transcendent utility in that.</p>

Good for gigabit ethernet (and separate power!), just remember to lube it up well first</p>

<p><span class="h-card" translate="no"><a href="https://radiosocial.de/@hennichodernich" class="u-url mention">@<span>hennichodernich</span></a></span> this is exactly what glasgow does! though 30 ohms still results in a lot of crosstalk</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> yes. Yes, yes, yes.<br />Use IDC cables with every second wire grounded and 22 to 33 ohms series resistors on the TX side.</p>
