In the past decade or two, I&amp;#x27;ve seen computer science lose its collective appreciation of the staggering potential of hardware. This has steadily resulted in software being built with tremendously over-engineered, hyper-complicated, cloud-first architectures that barely match the throughput of a single box running a high-performance platform (and for the record, &amp;quot;high performance&amp;quot; can still be relatively ergonomic via Java, C#, Rust, and so on).&lt;p&gt;The scale of hardware, clock cycles, bits per second of bandwidth, etc., being squandered on modern cloud-first highly complicated architectures boggles the mind.&lt;p&gt;I fear there is no strength behind any pendulum swing back to architectural simplicity, appreciation of the available capacity of hardware and how to use it, and local-first.</text><parent_chain></parent_chain></comment><story><title>On the strange joys of mainframe OSes that have survived into modern times</title><url>https://liam-on-linux.dreamwidth.org/86995.html</url></story>

I don&amp;#x27;t think I ever used a proper mainframe, and I honestly wanted to know more. The author keeps building up to this massively different, otherworldly system, and then just finishes without ever answering.&lt;p&gt;I did feel some contempt towards certain developers (who dare call themselves software engineers) and there was definitely an &amp;quot;old man yelling at cloud&amp;quot; undercurrent. If only I could learn something of merit, that would have been worth it.&lt;p&gt;So I guess it&amp;#x27;s up to us plebs to go and see what makes mainframes so different. How the &amp;quot;weird&amp;quot; custom architectures work. What&amp;#x27;s it like to work on one and write code for it.</text><parent_chain></parent_chain></comment><story><title>On the strange joys of mainframe OSes that have survived into modern times</title><url>https://liam-on-linux.dreamwidth.org/86995.html</url></story>
