软件推荐: Dream Aquarium

最初听说Dream Aquarium是在一个介绍如何把它嵌入Beryl桌面的帖子，当时wine安装都没成功。

最近在Windows试了下, 确实不错。很有趣的屏保。

最新试用版是1.1040, 而最新正式版似乎是1.1090

破解不大好找，但确实能找到，我找到的链接给删掉了，好像是在www.leehare.cn.

A Rocky Migration: Moving from docker-compose to Podman and gVisor

I've been running a few containers for several years. They were all running under rootless Docker with a single user. Initially, I planned to migrate the containers to VMs , but I couldn't get a stable workflow after about two months of effort. Later, gVisor caught my attention , and I decided to migrate to Podman with gVisor instead. The new plan is to run each container with --userns=auto and use Quadlet for systemd integration. This approach provides better isolation and makes writing firewall rules easier. I'm now close to migrating all my containers. Here are a couple of rough edges I'd like to share. Network Layout I compared various networking options and spent a few hours trying the one-interface-per-group approach before giving up. I settled on a single macvlan network and decided to use static IP addresses for my containers. To prevent a randomly assigned IP address from conflicting with a predefined one, I allocated a large IP range for my ...

Exploring Immutable Distros and Declarative Management

My current server setup, based on Debian Stable and Docker, has served me reliably for years. It's stable, familiar, and gets the job done. However, an intriguing article I revisited recently about Fedora CoreOS, rpm-ostree, and OSTree native containers sparked my curiosity and sent me down a rabbit hole exploring alternative approaches to system management. Could there be a better way? Core Goals & Requirements Before diving into new technologies, I wanted to define what "better" means for my use case: The base operating system must update automatically and reliably. Hosted services (applications) should be updatable either automatically or manually, depending on the service. Configuration and data files need to be easy to modify, and crucially, automatically tracked and backed up. Current Setup: Debian Stable + Docker My current infrastructure consists of several servers, all running Debian Stable. System Updates are andled automatically via unattended-upgrades. Se...

mkosi: First Impressions

I stumbled upon the Gentoo wiki page for systemd-nspawn , which in turn led me to nspawn.org , mkosi , and later systemd-sysupdate . mkosi quickly caught my eye because it's almost exactly what I wanted to build myself, as mentioned in a previous post . So, I decided to spend my "sysadmin fun quota" on it. Overview mkosi is similar to docker build or podman build , but it's designed for creating full OS images. It focuses on development and testing. For example, much like nix-shell , mkosi can quickly launch a sandboxed shell with a specific distribution and selected packages installed. The systemd project itself uses mkosi for testing across different distros. The re-introduction article is a great read. Speed Note that this is by no means a rigid benchmark. My setup is an SSD with LUKS and an ext4 filesystem (without reflink support). Building Container Images mkosi is pretty fast. A simple mkosi command creates a fresh Debian image. I used the --incrementa...
