I had already finished the move from Netlify to Cloudflare on my other blog, and since the summer holidays gave me some time, I did the migration on this site too.
It was almost the same work as the migration on the other blog, so I was able to move over fairly easily.
Github To link it with Cloudflare, set the repository in question to allow the integration.

When I tried to connect from macOS to a QNAP’s Samba share for the first time in a while, for some reason I was denied and could not log in even though I was entering the correct password.
For reference, the macOS here is the latest Sonoma environment.
Investigation Logging in from Windows works fine Logging in over afp works fine Logging in from older macOS (High Sierra or Mojave) works fine too How to fix it Either method is fine as long as it solves the problem

TL;DR To answer the request to use a GPU (nvidia) inside a Docker container, Docker has to be configured for GPU support.
Normally a Docker container cannot access the host’s GPU resources. That is because Docker does not pass the host’s GPU devices through to the container, and the reason behind it is that the GPU driver and the CUDA libraries are not properly shared between the host and the container.
To get around this, the GPU resources have to be passed through to the container with a tool such as nvidia-container-toolkit.

I only just learned the command that updates plugins in a Neovim (Vim) setup that uses vim-plug.
Until now I opened nvim, opened the : command window, and typed :PlugUpdate. That is fine for a single machine, but repeating the same steps on several hosts is tedious. It turns out you can run it from the command line as well.
$ nvim +PlugUpdate +qall
With this, you can drop it into a script or an Ansible playbook.

Ever since I started using a Mac, I kept wishing there were a feature like the one on Unix where simply moving the mouse cursor onto a window makes it active.
It is late in the day, but I finally came across a piece of software with a Focus Follows Mouse feature (AutoRaise).
Installing AutoRaise The installation instructions offer a disk image, a Zip file and manual compilation, but the disk image was not supported, so I go with manual compilation from Git.

Until a few years ago I had sync configured across several PCs with Dropgox, but a change for the worse in Dropbox put a limit on the number of devices, so these days I use Resilio Sync to keep my PCs in sync.
Lately I have been using node-based tools such as React and Git frequently, and if I keep those working directories inside a Resilio Sync folder, an enormous number of files get synced.
In particular, I do not want the contents of node_modules produced by node builds, or the git management folder, to be synced, so - late in the day though it is - I began to wonder whether Resilio Sync has an exclusion setting.

In Linux environments I often have occasion to add an HDD after the fact, so I am writing it down again.
(About ten years ago I posted a similar article (adding an HDD with fdisk from the command line (in Japanese)))
Environment The Linux used is Debian 12 The format is xfs The HDD to be added is 4TB I assume Linux (Debian) is already running and the HDD to be added is already installed

When I rebuilt and started, for the first time in a while, a container that uses external in order to communicate between containers in different Docker environments, I ran into the error below
Copy network default: network.external.name is deprecated. Please set network.name with external: true The docker-compose.yml I had been using until then worked with the following
Copy … networks: default: external: name: ${NETWORK} The compose version has gone up and the way it is written seems to have changed, and the format below is apparently the correct one

I have written about Debian upgrades several times, so this update is almost the same work as the previous Upgrading Debian 10 to 11
.
The only difference is a small change to sources.list when adding non-free. After main in each repository stanza of /etc/apt/sources.list, add non-free non-free-firmware.
#deb cdrom:[Debian GNU/Linux 12 _Bookworm_ - Official Snapshot amd64 LIVE/INSTALL Binary 20230610-08:51]/ bookworm main non-

As an aside, a direct jump from 10 to 12 failed in my case, so when upgrading from an older release it is safer to go in order (10→11→12).
