An engineering manager that I have the privilege of working with just asked me for three expectations of a principal engineer for a project that he is working on to mentor senior engineers at Twilio. Here is the list that I came up with.

• Skate to where the puck is going: Are you waiting to be told what to do or are you getting a sense for our product vision and making concrete suggestions for what technical work needs to be done to get us in a good place when it becomes time to execute?
• Act like an owner: Are you complaining about what's broken or offering solutions and/or alternative ways of thinking that makes it clear to engineers close to the problem that they can play an important role in solving those problems? Do you accept the world as it is or are you willing to provide a compelling vision for how it could be?
• Teach and lead: You're not getting more hours in the day. Taking on all of the hard work not only makes you a single point of failure, it robs your colleagues of the ability

Some things that are "better" with this BetterPromise implementation:

• BetterPromise # then(..) accepts a BetterPromise (or Promise) instance passed directly, instead of requiring a function to return it, so that the promise is linked into the chain.

  var p = BetterPromise.resolve(42);
  
  var q = Promise.resolve(10);
  
  p.then(console.log).then(q).then(console.log);

# By default, Docker containers run as the root user. This is bad because:
#   1) You're more likely to modify up settings that you shouldn't be
#   2) If an attacker gets access to your container - well, that's bad if they're root.
# Here's how you can run change a Docker container to run as a non-root user

## CREATE APP USER ##

# Create the home directory for the new app user.
RUN mkdir -p /home/app

Python: How to print the full traceback without exiting the program?

The exception handling block except Exception as ex: print(ex) will only print the exception message and not its traceback.

That’s good to know, but we need more info than this to debug properly. Namely the line that raised the exception, together with its stack trace.

The traceback module, part of the stdlib, will help us with this:
