Staring at this board, mentally converting PCIe lane count to device requirements, only to consider that yet again... It's 2025. We're still using the PCIe slot standard for most motherboards, even on enterprise boards. Who's doing this right, at least marginally so? ASRack (brain, please grow up and stop making elementary jokes) has been putting four physical x16 slots on their "Deep mini-ITX&
The Q4-2024 through Q2-2025 cycle has been one of remarkable instability for Fedora kernels and systemd breaking-changes. F40 through F42 have offered more crashes, more kernel panics, and more core dumps than any triple-set of versions since its dawning into existence - and I've been running this distro for dev-only boxes since the first release. In the worst of circumstances, Fedora notified me of a firmware update, which
Some additional reorganization time this weekend, all busy with the process of preparing the HomeLab for another interstate relocation. Having decided to repurpose some hardware to create a new router, this one formerly hosted infra VMs several years ago, but now it's going to run a pair of "BSD Router Project" VMs for on-host H/A, and a bit of packet shuffling between hosts for RDMA
While using Soundcloud the other day, prompted by a little helper fellow which states: > "Import your Spotify Playlists!" ok, sure. I'd like to use a single app for music if possible, and I prefer Soundcloud to Spotify in general. So, I click ok and authorize the apps' APIs to do their thing. It finishes importing. Great, back to work. Life goes on. Days later,
Thunderbird, wtf are you doing where you need 83% CPU plus ~50GB (virt) and 20G (res) of RAM allocated? The entire mailbox isn't even 1GB in total size. Yet here it is, cranking out all of this nebulous processing 24/7... literally 24/7 it's running loads like this for months now. Generally I ignore it because the workstation has a modern EPYC with 32 cores
Some quick progress notes for a few FreeBSD and OpenZFS devs, which will be accessing one of my POWER9 systems. See photos for visual reference. * Separate L1 and L2 domain for all network access, zero-shared DMZ, unconnected to the rest of the RFC99 lab lack * Mikrotik router has been temporarily slapped into place on the side of my lab rack, directly in back of the Talos II system (dual socket,
I love a lot about the linux world, and there's a lot of positive aspects to the kernel itself, which has brought a lot of joy over the years, with kernel module development, debugging, tuning, analyzing... specifically for my career, but also on a personal level. For one quarter of a century I've been using Linux and BSDs in many different flavors, but there's
