 The docker binary and daemon are largely being replaced and deprecated in favor of podman in the RedHat distros that metalk8s targets. I fully support this change, podman is a great open source tool that listens to user feedback and has far outstripped Docker in capabilities and security features.</description></item><item><title>Combining "Subscribers" in Rust's Tracing Library</title><link>https://stelfox.net/blog/2023-03-13-chained-tracing-subscribers/</link><pubDate>Thu, 13 Apr 2023 20:51:02 -0400</pubDate><guid>https://stelfox.net/blog/2023-03-13-chained-tracing-subscribers/</guid><description>Tracing is a fantastic Rust library that I&amp;rsquo;ve found immensely useful, but I feel its documentation and API could still use a bit of polish.

 So, I&amp;rsquo;m thinking I need multiple &amp;ldquo;Subscribers&amp;rdquo; for the various events being traced, right?</description></item><item><title>Logical Volume in Use</title><link>https://stelfox.net/blog/2020-02-23-logical-volume-in-use/</link><pubDate>Sun, 23 Feb 2020 20:09:02 -0400</pubDate><guid>https://stelfox.net/blog/2020-02-23-logical-volume-in-use/</guid><description>While attempting to automate some filesytem creation that involved LVM I kept running into an issue occasionally with some holding open the logical volumes. I would attempt to disable the volume using the following command:
 $ lvchange -an system/storage Logical volume system/storage contains a filesystem in use. All of the mounts for the filesystems that were on the volume were unmounted, so it must have been a process. The trick to finding this out is to query all the processes mount files to find out what is holding this open.</description></item><item><title>Extracting Dracut Built initramfs</title><link>https://stelfox.net/blog/2020-02-18-extracting-dracut-initramfs/</link><pubDate>Tue, 18 Feb 2020 18:42:02 -0500</pubDate><guid>https://stelfox.net/blog/2020-02-18-extracting-dracut-initramfs/</guid><description>It&amp;rsquo;s been a hot second since I&amp;rsquo;ve dived into the lands of initramfs and since then it seems like things have gotten more complicated. This is the way of things in tech and usually has a good reason. The simple way that used to work wonders (and is still required) to start with, was to identify if the file is compressed:

I generally use cronie as my cron daemon with the associated anacron. Cron runs tasks periodically, and anacron helps ensure that a missed task will get run if it was off or powercycled when it would have otherwise run.
 File Format The config format differs slightly between crontabs, regular cron files, and anacron entries. At the beginning of all the files environment variables can be set using key=value pairs to control the behavior of cron and anacron followed by entries for that file one to a line.</description></item><item><title>Syslog-NG</title><link>https://stelfox.net/notes/syslog_ng/</link><pubDate>Wed, 25 Oct 2017 01:56:02 -0400</pubDate><guid>https://stelfox.net/notes/syslog_ng/</guid><description>Syslog-NG is a fast, reliable, and secure syslog daemon that can do advanced processing and log centralization while maintaining a sane configuration file syntax. I&amp;rsquo;ve recently come to vastly prefer it over my previous long term favorite Rsyslog.
 It&amp;rsquo;s important to note that when modifying the logs statements, they will be processed in order. This means log statements that finalize a message will never make it past that statement. This finalization behavior can be a great tool for optimizing the processing path of logs but can result in unexpected behavior if you don&amp;rsquo;t pay attention when re-ordering the statements.</description></item><item><title>CFSSL</title><link>https://stelfox.net/notes/cfssl/</link><pubDate>Tue, 24 Oct 2017 18:39:22 -0400</pubDate><guid>https://stelfox.net/notes/cfssl/</guid><description>CFSSL is a toolkit of utilities for TLS PKI infrastructures and supports more functionality than I&amp;rsquo;ve personally needed. It is a fast and convenient way to setup and manage a multi-layer internal certificate authority.
 I&amp;rsquo;ve used it to generate an internal root CA, with sub-CAs for internal only server certificates, and separate CAs for each domain of client certificates (such as VPN, log, mail, and LDAP servers). This allows the root CA to be protected more stringently than specific domains.</description></item><item><title>Server Naming Convention</title><link>https://stelfox.net/notes/naming_scheme/</link><pubDate>Fri, 20 Oct 2017 19:59:02 -0400</pubDate><guid>https://stelfox.net/notes/naming_scheme/</guid><description>Over the years I&amp;rsquo;ve found myself using many different naming schemes for servers under my control.

 WhisperPush is an implementation of Moxie Marlinspike&amp;rsquo;s highly respected TextSecure and I was very excited at the possibility of using it.</description></item></channel></rss>

 I got a hold of a Zynq 7100 development board, and while I&amp;rsquo;ve played with some embedded ARM microcontrollers such as the STM32F3 series and more basic RISC style microcontrollers like Atmel&amp;rsquo;s SAMD10 and Atmega lines, I&amp;rsquo;ve never played with FPGA development before so I considered this an interesting learning opportunity.</description></item></channel></rss>
