LLMs and an old dev

Coding Career

A lot of developers seem to be afraid of generative AI and LLMs because it may replace their jobs.

But as an older developer who sometimes has a hard time keeping up with new frameworks and technologies, LLMs have been life-saving. Not only is my productivity high, but I am also able to keep up with new languages and codebases and be productive almost immediately. I used to think about moving to management because it seemed I could not keep up with tech, but now I have new confidence that I can keep doing my hobby as a profession for another few years.

Maybe eventually AI will replace my job, but learning to use it effectively may extend my career a bit longer.

So I decided to use a simple bash script to build and deploy the site.

This error in our Rails application drove me crazy. The error was like this: undefined method xxxxxx' for #<Hash:0x000000001234> The problem was that I was calling a method like this: a_method(var: var) And the method definition was like def a_method(var: var) which resulted in something called variable shadowing and caused clash between variable passed in the method and local variable being defined. The fix was to change method definition to def a_method(var:)
