So, I upgraded my server to the latest Ubuntu release and Wallabag broke. I remember I had a tough time upgrading Wallabag. So this time, I decided to run it as a Docker container to avoid issues.
Unfortunately, this also had a few challenges!
Most of the stuff on my server run using flat files or SQLite databases, so I referred to the official Wallabag docs for running it on Docker. It gave the docker run command, but I wanted it as a docker-compose.yml file instead.
Do not take life too seriously. You will never get out of it alive.

Recently, writing a plain Roda app, I was facing a caching problem. I had a list and a detail page and whenever there was a list item clicked on I was using the flash plugin to maintain the item selected and highlighting the item when the list page was loaded.
However, on navigating back via the browser button, the cached page was showing up and the highlight would be on the previous selected item or not there at all.

I’ve become a big fan of fzf since I discovered it.
However, after a recent upgrade, when I pressed Ctrl+R, I got the following error –
unknown option: --scheme=history
After some searching, found the following solution.
Remove fzf from /usr/bin/ and relink it.
Run these two commands in order –
sudo rm /usr/bin/fzf sudo ln -s ~/.fzf/bin/fzf /usr/bin/fzf
Since I installed fzf on Linux, I also wanted it in my Windows Powershell prompt.
To install fzf
winget install fzf
And then to get keyboard shortcuts working, following lines need to be added in the profile.ps1
Remove-PSReadlineKeyHandler 'Ctrl+r' Remove-PSReadlineKeyHandler 'Ctrl+t' Import-Module PSFzf
fzf is a serious timesaver. To be able to quickly go through past commands and in a fuzzy manner, especially when you don’t recall the exact command is a Godsend!
To install fzf on Linux, we need to
a) clone the repository into the system
git clone --depth 1 https://github.com/junegunn/fzf.git ~/.fzf
b) run the command which will add the relevant shortcut keys
~/.fzf/install --all
There are a bunch of other stuff that can be done once fzf is installed. For example, to see instant file previews –
fzf --preview 'less {}'
And if there is bat also installed, then the previews can show syntax highlighting and line numbers also!
fzf --preview 'bat --color=always --style=numbers --line-range=:100 {}'
A number of times, I want to create a Window Subsystem for Linux instance out of a Docker container.
The main reason for doing something like this is when a particular Linux version is not available for WSL.
The steps to follow –

Multiple times when I change the path on Windows, via the ‘Environment Settings’ dialog, those changes don’t apply.
Even when I reopen the command prompt, the settings don’t seem to be there.
So, either I would log out of Windows completely and log back in or do a system restart. This was a big pain and God knows how much time I’ve wasted with this!
Recently, I got tired of this and decided to dig in a bit deeper and finally found the answer!

Of course, we can set up Nginx, or something else. But to this quickly and easily, and mostly, only temporarily, we can do this using many different languages quite easily.
