Finally, the separate box of POWER9 upgrades appears. These are for the dual socket 144 thread Talos II here at home (the LC-922 are in colo). Relocation has turned up a lot of missing hardware, very pleased about this turn of events.

So, the long lost box contains:
- 4x Samsung 883-DCT 2TB SSDs for local storage ZFS pool (with 2x Optane NVMe cache)
- 3x PM863a 240GB SSDs for the OS
- always more RAM
- an OcuLink 4x to U.2 cable w/ Optane drive floating around somewhere
- Mellanox 50GbE QSFP28 NIC for RDMA fun

@dexter finally, we can continue the project with appropriate hardware

Some how I am very envious of the 60MB RAM footprint while booting into a #linode #vps. The best I could get onto my #homelab is 300MB usage on a #Ubuntu cloud image. This is unfortunately the same as my desktop #ArchLinux with #KDE running.

The Ubuntu server image idled at 600MB RAM usage with #docker & #sshd. The culprits using most ram are #snapd & #multipathd.

Credentials shouldn't be around in plain text files. But I also don't want to set up a fully fledged credentials management solution for my homelab.

Wouldn't it be nice to dynamically load the credentials I need when I step into my work directory, and remove then when I leave it?

Let's use @bitwarden and direnv to keep credentials safe in all simplicity!

Thanks to SeaweedFS, I've set up two replicas of the BSD Cafe's media. One is on a backup server (for disaster recovery purposes only, also containing the hourly zfs-autobackup backups), and the other is on a Raspberry Pi 4 running FreeBSD, which is one of my home backup servers - just one meter away from my desk.
I've also configured Nginx in a jail, so when I'm at home, the BSD Cafe's media is served directly from the local replica.
The performance is lightning fast.

I don't think I've done an #introduction before despite having been here for a few years now.

My name is Nagaram or Nags. I am kinda 30. #tech nerd #history nerd #philosophy nerd and I will talk ad nauseum about #religion and my weird #atheist stances. Such as thinking #magick and the #occult is cool!

I work #IT so I mostly talk about that and my #homelab like my blog thinkstoomuch.net

I'm also an annoying leftist! I will post about my #gun ownership and #firearms training with anyone who's interested.

DMs open. Email is open too if you wanna chat, vent, or call me names. All valid!

Well, it's time. I'm releasing my tool that lets you aggregate patch and update status of hosts over ssh on unix-like systems.

The github repository has details as well as links to the exhaustive documentation.

It is my hope that at least another person finds it useful

A poor quality animated gif of the exosphere CLI, showing hosts in a nice table. The UI is then launched, showing a dashboard of green tiles with a host in each. A command is launched and a modal dialog box shows up, then the inventory screen is switched to. The table shows hosts, their status and available updates, some of them are categorized as "security updates", in red. A host is selected, which opens a pane on the right displaying the details as well as a detailed list of updates. An update is selected, and another panel opens up, from the left this time, displaying the patch details. Current version, new version, source, etc.
