Several things have changed significantly since then — <code>tcp_fack</code> and <code>route.flush</code> have been removed from modern kernels entirely, the recommended window sizes are far too conservative for today&rsquo;s connections (modern kernels auto-tune well beyond 512KB by default), and ECN is now widely supported and should generally be <em>enabled</em>, not disabled. If you&rsquo;re trying to tune a modern Linux system for broadband, please look for a guide targeting the current kernel. Don&rsquo;t copy-paste the <code>sysctl.conf</code> block below onto anything running kernel 4.x or later.</p></blockquote> http://www.santa-li.com/about/ Mon, 01 Jan 0001 00:00:00 +0000 http://www.santa-li.com/about/ <h2 id="about-me">About Me</h2> <p>My name is Stu. I&rsquo;m a Systems Architect on the Infrastructure Systems team at BeyondTrust (a Privileged Access Management company), working out of their Southern California office. My team manages physical and virtual infrastructure across multiple datacenters, supporting a diverse mix of hypervisor platforms — including VMware, OpenShift Virtualization, Nutanix, and Hyper-V — along with enterprise Unix systems like IBM Power/AIX and Oracle VMS.</p> <p>My current work sits at the intersection of infrastructure modernization, automation, and platform evaluation: migration projects, capacity planning, and keeping complex, heterogeneous environments reliable while improving their economics and manageability. Recently that&rsquo;s meant deep dives into OpenShift Virtualization, Nutanix, and OpenStack as part of a broader move away from VMware, alongside expanding infrastructure automation with Ansible, workflow automation with n8n, and integrating AI tooling to reduce toil and improve how we build and manage systems.</p> http://www.santa-li.com/links/ Mon, 01 Jan 0001 00:00:00 +0000 http://www.santa-li.com/links/ <h3 id="i-n-f-o-r-m-a-t-i-v-e">I n f o r m a t i v e</h3> <ul> <li><a href="http://slashdot.org/" target="_blank" rel="noopener noreferrer">Slashdot</a> </li> <li><a href="http://www.antionline.com/" target="_blank" rel="noopener noreferrer">AntiOnline</a> </li> <li><a href="http://www.linux.com/" target="_blank" rel="noopener noreferrer">Linux.com</a> </li> </ul> <h3 id="t-e-c-h-n-i-c-a-lt-r-a-i-n-i-n-g">T e c h n i c a l  &amp;  T r a i n i n g</h3> <ul> <li><a href="https://www.cbtnuggets.com/" target="_blank" rel="noopener noreferrer">CBT Nuggets</a> </li> <li><a href="https://udemy.com/" target="_blank" rel="noopener noreferrer">Udemy</a> </li> </ul> <h3 id="l-i-n-u-xo-p-e-ns-o-u-r-c-e">L i n u x  &amp;  O p e n  S o u r c e</h3> <ul> <li><a href="http://www.tldp.org/" target="_blank" rel="noopener noreferrer">Linux Documentation Project</a> </li> <li><a href="http://www.justlinux.com/" target="_blank" rel="noopener noreferrer">JustLinux</a> </li> <li><a href="http://www.gentoo.org/" target="_blank" rel="noopener noreferrer">Gentoo ( My personal favorite Linux! )</a> </li> <li><a href="http://www.ubuntu.com/" target="_blank" rel="noopener noreferrer">Ubuntu ( My current main distro )</a> </li> <li><a href="https://www.centos.org/" target="_blank" rel="noopener noreferrer">CentOS</a> </li> <li><a href="http://www.redhat.com/" target="_blank" rel="noopener noreferrer">Red Hat</a> </li> <li><a href="http://fedoraproject.org/" target="_blank" rel="noopener noreferrer">Fedora</a> </li> <li><a href="http://www.opensuse.org/" target="_blank" rel="noopener noreferrer">openSUSE</a> </li> <li><a href="http://www.debian.org/" target="_blank" rel="noopener noreferrer">Debian</a> </li> <li><a href="http://www.server-world.info/en/" target="_blank" rel="noopener noreferrer">A handy set of CentOS/RedHat Guides</a> </li> </ul> <h3 id="u-n-i-x">U N I X</h3> <ul> <li><a href="https://www.talisman.org/unix/rosetta.shtml" target="_blank" rel="noopener noreferrer">UNIX Rosetta Stone ( There are a couple of these out there )</a> </li> <li><a href="http://aix4admins.blogspot.com/" target="_blank" rel="noopener noreferrer">AIX for System Administrators</a> </li> </ul> <h3 id="u-n-i-xv-i-r-t-u-a-l-i-z-a-t-i-o-n">U N I X  V i r t u a l i z a t i o n</h3> <ul> <li><a href="http://aix4admins.blogspot.com/2011/06/vios-service-package-definitions-fix.html" target="_blank" rel="noopener noreferrer">Useful VIOS Commands</a> </li> <li><a href="http://www.aixhealthcheck.com/blog?topic=33" target="_blank" rel="noopener noreferrer">Backing up VIOS</a> </li> </ul> <h3 id="s-p-e-e-d-i-n-gt-h-i-n-g-su-p">S p e e d i n g  T h i n g s  U p</h3> <ul> <li><a href="http://www.speedguide.net/" target="_blank" rel="noopener noreferrer">Speed Guide ( their broadband forums rock! )</a> </li> </ul> <h3 id="a-n-i-m-em-a-n-g-a">A n i m e  &amp;  M a n g a</h3> <ul> <li><a href="http://www.animenewsnetwork.com" target="_blank" rel="noopener noreferrer">Anime News Network ( Great site for anime info! )</a> </li> <li><a href="https://mangadex.org/" target="_blank" rel="noopener noreferrer">MangaDex ( Online Manga Reader )</a> </li> <li><a href="https://www.mangaupdates.com/" target="_blank" rel="noopener noreferrer">Bake-Updates Manga ( Manga Info site )</a> </li> </ul>
