Disable browser caching in Ruby Roda app

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.

fzf – error when pressing Ctrl+R

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

Install fzf for Powershell on Windows

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

install fzf on Linux

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 {}'

Windows – Path changes not updating

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!

upgrading bitwarden / vaultwarden

I had posted earlier about running Vaultwarden (a Bitwarden server in Rust). This has been running amazingly all this time.

But today, when I tried to log in from the browser extension, I kept getting an error.

Searching in the forum, I found the issue – I had to update the Vaultwarden server.

Since I was running Vaultwarden as a Docker container, and I had run the docker command directly, so I decided to create a docker-compose.yml file instead this time.
