It’s time to take a break, stretch our legs, grab a drink, and maybe even join in some interesting conversations around the water cooler as Michael goes off script, Joe is very confused, and Allen insists that we stay on script.
The full show notes for this episode are available at https://www.codingblocks.net/episode163. Stop by, check it out, and join the conversation.

Meantime, at the watercooler….
GitHub Copilot (GitHub)
- In short, it’s a VS Code Extension that leverages the OpenAI Codex, a product that translates natural language to code, in order to … wait for it … write code. It’s currently in limited preview.
What’s the value?
- Is the code correct? Github says ~40-50% in some large scale test cases
- It works best with small, documented functions
- Does having the code written for you steer you towards solutions?
- Could this encourage similar bugs/security holes across multiple languages by people importing the same code?
- Is this any different from developers using the same common solutions from StackOverflow?
- Could it become a crutch for new developers?
- Better for certain kinds of code? (Boiler plate, common accessors, date math)
- Boiler Plate (like angular / controller vars)
- Common APIs (Twitter, Goodreads)
- Common Algorithms, Design Patterns
- Less Familiar Languages
- But is it useful? We’ll see!
Is this the future?
- We see more low, no, and now co-code solutions all the time, is this where things are going?
- This probably won’t be “it”, but maybe we will see things like this more commonly – in any case it’s different, why not give it a shot?
Is it Ethical?
- The “AI” or whatever has been trained on “billions of lines” of open-source code…but not strictly permissive licenses. This means a dev using this tool runs the risk of accidently including proprietary code
- Quake Engine Source Code Example (GPLv2) (Twitter)
- From an article in VentureBeat:
- 54 million public software repositories hosted on GitHub as of May 2020 (for Python) 179GB of unique Python files under 1MB in size. Some basic limitations on line and file length, sanitization: The final training dataset totaled 159GB.
- There is problem with bias, especially in more niche categories
- Is it ethical to use somebody else’s data to train an AI without their permission?
- Can it get you sued?
- Would your thoughts change if the data is public? License restricted?
- Would your thoughts change if the product/model were open-sourced?
Abstractions… how far is too far?
- Services should communicate with datastores and services via APIs that hide the details, these provide for a nice indirection that allows for easier maintenance in the future
- Do you abstract at the service level or the feature level?
- Are ORMs a foregone conclusion?
- What about services that have a unique communication pattern, or assist with cross cutting concerns for things like microservices (We are looking at you hear Kafka!)

Some of Michael’s (Linux/macOS) favorites from the article:
- Abbreviate your directories with tab completion when changing directories, such as
cd /v/l/a, and assuming that that abbreviated path can uniquely identify something like,
/var/logs/apache, tab completion will take care of the rest.
nl to get a numbered list of some previous command’s output, such as
ls -l | nl.
ERRATUM: During the episode, Michael mentioned that the output would first list the total lines, but that just happened to be due to output from
ll and was unrelated to the output from
- On macOS, you can use the
powermetrics command to gain access to all sorts of metrics related to the internals of your computer, such as the temperature at various sensors.
!! to repeat the last command. This can be especially helpful when you want to do something like prepend/append the previous command, such as
ERRATUM: Wow, Michael really got this one wrong during the episode. It doesn’t repeat the “last sudo command” nor does it leave the command in edit mode. Listen to Allen’s description. /8)
- Awesome keyboard shortcuts:
CTRL+A takes you to the start of the line and
CTRL+E takes you to the end.
- No need to type
clear any longer as
CTRL+L will clear your screen.
CTRL+U deletes the content to the left of the cursor and
CTRL+K deletes the content to the right of the cursor.
- Made a mistake in while typing your command? Use
CTRL+SHIFT+- to undo what you last typed.
- Using the
history command, you can see your previous commands and even limit it with a negative number, such as
history -5 to see only the last five commands.
