Fixing "sed: command i expects \ followed by text" error

I ran into a very weird error today. While trying to automate the deployment for this blog, I needed to replace a string in a file. The internet tutorials [1, 2, 3, 4] told me that sed would be perfect for this job and the following command should work: sed -i 's/search_string/replace_string/' filename The Error However, I kept getting tripped up by the following error: sed: 1: "i2.html": command i expects \ followed by text I spent a bunch of time trying to make sure I escaped the right characters in my strings but the error was persistent!...

How Spotify is Killing the Open Podcast Ecosystem

Earlier this year, when Spotify announced that “The Joe Rogan Experience” would stream exclusively on Spotify, it sent shockwaves throughout the podcast ecosystem. This deal – reportedly worth over $100 million – is one of the most lucrative podcast deals. The presence of this deal, let alone the magnitude, is rare for the podcast ecosystem, which is built on open principles i.e. all podcasts are available everywhere.

What Happens When Your LinkedIn post goes viral!

What is LinkedIn? I have never really discovered the value of LinkedIn until about a year ago when I started using it seriously to search for a new job opportunity. I have always viewed it as a Facebook clone with a horrible and inconsistent UI. But I was surprised to discover that LinkedIn had updated their UI with a copy-paste job from Facebook. Using LinkedIn is now a much more pleasant experience!...
