Livebook is very powerful application which can be used in many different ways with your Phoneix project. I have few apps running on my VPS and sometimes I would like to run some functions without creating interface for them from admin side, such as cache clean up. Perhaps run some analytical queries to the database and much more.

Meet PhonenixPlayground

I found this library on github suggestions and I always wanted to have something simple and quick to test out LiveView prototypes. What can be quicker than opening Livebook and trying something there? Folks behind PhonenixPlayground made both of my wishes come true!

If you would like jump straight into the code:

In August 2023, I opened my own LLC to run a fractional CTO/consulting business. After almost a year, I learned some important things that could be useful for people who would like to make a change in their career.

1. Never trust anyone unless the contract is signed and the invoice is paid.

As the title says, a potential client might be eager to work with you, but when it comes to the actual contract and work, they might suddenly disappear without any signs of life, even people with whom you thought you had a nice relationship. Lower your expectations to zero or sometimes below zero. Once the contract is signed and the invoice is paid, you can have a small relief. (This happened to me 9 out of 10 times, maybe something is wrong with me)
