Today I learned about many?, which is a convenience method in ActiveSupport for determining if there is more than one record present. It's similar to any?, but the key difference is many? is strictly greater than, whereas any? is greater th…

I've "always" known about Ruby's compact method to get rid of nil values. # Enumerable.compact [1, "a", nil, " ", [], {}].compact => [1, "a", " ", [], {}] However, I just learned that as of Rails 6.1 there has been a compact_blank method to…
I connect to a Fedora box for some development work over SSH. This works great, but fairly frequently the connection will hang for a couple of seconds. The keypresses aren't lost, but the display is frozen during this period - making intera…

You can use the retry keyword to re-attempt code execution after an error is raised. A very primitive example would be - def do_something Service.call # might raise an error rescue retry end retry will call the code above the rescue again.
The bisect command can be used to traverse your commit history to find where an unwaned behavior was introduced. If your current commit is broken, and you have a previous working commit, but there's lots of commits in between, bisect will h…
