This post is raw. No grammar is checked. When doing local development or just tinkering with this or that, quite often you want to expose something to the Internet. When it’s just single “something”, then you can just forward your port 80 from router, to your machine’s “something” port. But this falls appart if you have two “something” you want to expose to the Internet. You can’t forward single 80 port from your router to two different applications running on your machine. Because one application will be running for example on 8080 port and the other on 8081. ...

Today I decided to ditch Flyway Desktop execution from CLI and integrate into my Sway + Wofi desktop environment. Basically, there is what you need: Get an Flyway icon and paste it into flyway.svg file Copy that SVG file into $HOME/.local/share/icons/hicolor/scalable/apps/flyway.svg Change the color for the icon by adding fill="#CC0200" to the path Create an $HOME/.local/share/applications/flyway.desktop file with the content like this: 1 2 3 4 5 6 7 8 9 10 11 12 [Desktop Entry] Version=1.0 Type=Application Name=Flyway GenericName=Database migration tool Comment=Database Migrations Made Easy Categories=IDE;Development Keywords=Database;SQL;IDE;JDBC;ODBC;MySQL;PostgreSQL;Oracle;DB2;MariaDB Exec=$HOME/.local/share/flyway/flyway-desktop/flyway-desktop --enable-features=UseOzonePlatform --ozone-platform=wayland --no-sandbox %U Icon=flyway Terminal=false MimeType=application/sql Because Flyway Desktop is Electron app, we are passing few flags to run it on Wayland system. If you still use Xorg, then just remove those flags. ...

Migrating old databases Currently mostly busy with modernizing 15 years old infrastructure of some customer. Old and huge MySQL databses. No foreign keys. No timestamps. It’s all pretty convoluted. Many VM’s running directly on KVM without libvirt abstraction. Failing hard drives. Old PHP. And the overaly of many “big brain” sysadmins. But at least, I gained full access to the most of the resources, restored passwords, established secure remote access, etc. ...

This post is a public draft, which may or may not be completed. As new thoughts come to mind, I may improve this article over time. PC Monitor setup I’ve been everywhere. From a single tiny 15" laptop to 4 screens + TV. But currently I’m at two monitor setup and even seriously considering one 32" 4K monitor setup. The thing about the multi-monitor setup is that it is misleading feeling about boosted productivity, because you “control” more things at once. In reality, you get more distracted from your current particular task. But most users doesn’t recognize that. I figured that out when suddenly one of my screens went into dark and I was lazy enough not to deal with that. Instead I just worked on a single screen for several weeks or even months. And you know… i liked it! At any single given time i have only one task in front of me. And the key for this comfort was customized key binds on my home row for quick workspace switch. I can navigate all my workspaces in a split second. Back and forward. I am huge proponent of mastering your keyboard and tailoring your navigation around the OS. Everything should be in the right place for no-effort execution. If navigation is pain for you, you will look for the things like 4 to 6 monitor setups which is just awful. ...
