Recently, while browsing Reddit, I came across one of the most useful tools I’ve seen: an email alias. As its name suggests, you can create alternative names for email addresses. These email addresses are linked to your main email address. The way it works is very simple: you create an alias, which is essentially another email address, and it gets linked to your main email address. When you send an email, it will forward all emails received by the alias to your main email address. ...

xargs is a great command that can help us to run commands from the output of another command. From tldr xargs: Execute a command with piped arguments coming from another command, a file, etc. The input is treated as a single block of text and split into separate pieces on spaces, tabs, newlines and end-of-file. For the examples we’re going to use the seq command: # Print 3 numbers seq 3 # 1 # 2 # 3 # xorgs wil print the numbers "inline" seq 3 | xargs # 1 2 3 # -n will use a max number of arguments per command line seq 3 | xargs -n 2 # 1 2 # 3 # -I is used to replace {} with the argument from the previous command seq 3 | xargs -I {} echo 'number {} printed' # number 1 printed # number 2 printed # number 3 printed # Create 1, 2, 3 folders seq 3 | xargs mkdir # Remove 1, 2, 3 folders seq 3 | xargs rm -rf

Sometimes you need to send to a third party service a different array structure than the one specified on Google Analytics 4 (GA4). So, in case you don’t want to create a new event only for this service and you want to reuse as much as posible a GA4 event like add_to_cart, then you need to map the GA4 built in array on GTM. This sounds pretty easy if you have used GTM (no server side) before, basically you create a new custom javascript variable and return the mapped array. However, on GTM using a server side container, the custom javascript variable is no longer available. ...

The Xbacklight no output have properties message can happen if your hardware has poor support or it can’t be detected properly by the xbacklight utility. This might be fixed by using an xbacklight wrapper called acpilight. acpilight can also be used to control the display and keyboard backlight on modern laptops. First, install the acpilight package: sudo pacman -Syu acpilight Add a udev rule to give access to users in the video group, this is needed because users don’t have permissions to alter sys files by default: ...

Arch Linux uses a package manager called pacman, as you may know this is pretty standard on any linux distro, however, I’ve seen that not all the people use the same way to install or upgrade packages. The simpler way you can install a package with pacman is: pacman -S package_name But, this will only install the package on your system and nothing else. You may say but that’s what I want basically, but due to the rolling release nature and since partial upgrades are not supported on Arch Linux this might not be the best approach in the long term and could even break your system. ...
