Nixie Clock: History
[Nixie Clock]
In my senior year of high school, the October 2006 issue of Nuts and Volts featured an article about a Nixie tube clock. The previous issue had discussed a high voltage power supply built around a PIC microcontroller. I had been experimenting with PIC microcontrollers for quite some time before and I was intrigued by the prospect of using a PIC microcontroller to generate a rather high voltage from a logic-level supply. I didn't have much use for it, though.…text/html2020-07-14T02:52:29+0100alex (alex@undisclosed.example.com)Publications - [2020]

Diskless PXE boot on NFS root
When you have a whole rack of machines and don't want to install and manage separate OS installs on all of them, setting up to boot via PXE with a shared NFS root can be a major time-saver. Here are some notes on how to set up both a host machine to act as the DHCP, TFTP, and NFS server, as well as how to set up the PXE-booted image. In this configuration, the control server will also act as a gateway machine for the PXE booted hosts.text/html2020-05-06T03:59:23+0100alex (alex@undisclosed.example.com)Unique machine ID for nfs root systems

Unique machine ID for nfs root systems
When multiple hosts running systemd share the same NFS root, they will also share the same machine-id. This can cause issues, especially with journald. Journald logging can be disabled by deleting /var/log/journaltext/html2020-05-06T03:41:09+0100alex (alex@undisclosed.example.com)Linux Tips and Tricks
