This Chrome courier bag has lasted me 16 years as my primary travel / laptop bag. Worth every penny. Now I have to find something as useful and valuable in the EU. Any recommendations?

I don't know who made this, but thank you.

2 images stacked, the first shows the standard trolley problem setup with one track resulting in the annihilation of one person, and a second with the annihilation of 5. A single decision maker stands with a lever and must choose whether or not to pull the lever to save 5 people, but doom one.

The bottom image shows the text, "git rebase master" and merges both tracks into a single track, resulting in certain annihilation of all 6 people.

You've heard me advocating for Erlang/Elixir for some years now. I've put together a short presentation about some of the practical reasons why I chose to pursue this tech. Practical Arguments for Erlang / Elixir

This is what I want in a Linux terminal... How can I get this? I will do anything.

Elixir code with the following: iex(1)> fn -> :this_function_returns_an_atom end
#Function<43.81571850/0 in :erl_eval.expr/6>
iex(2)> # now, i want to reference that function... so i use v() and the line number
nil
iex(3)> my_function = v(1)
#Function<43.81571850/0 in :erl_eval.expr/6>
iex(4)> # the elixir function invocation syntax is ".()" so I'll call that on my variable
nil
iex(5)> my_function.()
:this_function_returns_an_atom
iex(6)> # now I'll call it on the value of line 1 (the original function declaration)
nil
iex(7)> v(1).()
:this_function_returns_an_atom
