tmux zoom

https://youtu.be/Rn6mOarCQ-Y Zooming into the current split in tmux is a valuable tool to give yourself some screen real estate. These days I am almost always presenting, streaming, or pairing up with a co-worker over a video call. Since I am always sharing my screen I am generally zoomed in to a level that is just a bit uncomfortable, so anytime I make a split it is really uncomfortable, being able to zoom into the split I am focused on is a big help, and also help anyone watching follow where I am currently working. Default key bindings for zooming the current split I have rebound this to match the default binding with mod+z rather so that I get that single keystroke experience.

tmux new-window

https://youtu.be/YRPZBv-iYyE New window as it sounds makes new windows in tmux. Windows are kind of like tabs. They are another screen within your sessions that you can name and make new panes in. Default key bindings for creating and navigating windows in tmux. As always I have rebound these keys because I generally prefer a single keystroke over the prefix plus keybinding approach that tmux gives by default. When I started using tmux I did almost everything in one giant session with many panes and windows. It became a nightmare to manage and quickly get between two sets work efficiently. This year I leaned in on sessions quite heavily. Checkout this 👇 post to see that workflow in depth. How I navigate tmux in 2021 for more information on how I navigate tmux, check out this full post

tmux slect-pane

https://youtu.be/CPZJZjN9YTY These are my MOST often used keybindings that I use in tmux. They allow me to jump between splits with ease with a vim style layout. I can hold mod and jump between panes with a familiar arrow key. How I navigate tmux in 2021 for more information on how I navigate tmux, check out this full post

tmux rotate-window

https://youtu.be/06z5qf81ofo Rotate window is the main way that I navigated tmux before I learned. It allows you to change your focused pane, or rotate the position of the panes easily. Default keybindings My keybindings look just a bit different than the default ones, I do not like needing to hit prefix for every command, especially for repeated commands. I set a similar keybinding to the default one that uses mod instead of prefix. How I navigate tmux in 2021 for more information on how I navigate tmux, check out this full post

tmux select-layout

https://youtu.be/F0mHnwTrNNc When you get many splits going in tmux sometimes its time for a new layout. There are four layout strategies that I use, main-vertical, main-horizontal, even-vertical, even-horizontal. Almost always I am useing the main ones with mod plus a or mod plus shift a keybindings.

tmux resize-panes

https://youtu.be/hpFYE2LU7xc Resizing panes in tmux can be quite difficult in default tmux, I use a set of keybingings to help resize panes in the rare occasions that I do need just a bit more space. I set the keybinding to the same as my split navigation bindings but shifted. They are very vim like (h,j,k,l). Most often when I need to resize panes I just grab the edge of the pane with my mouse. Yes the mouse, its not that often that I actually need to change the size of a pane. How I navigate tmux in 2021 for more information on how I navigate tmux, check out this full post

tmux choose-tree

https://youtu.be/79Y-kqAiMpw Choose tree is a powerful tmux utility that provides a graphical interface to preview all sessions, windows, and panes, move between them kill them, move them and much more. The default keybinding my preferred keybinding to open sessions and windows collapsed and Zoomed in.

tmux prefix

https://youtu.be/BMkpbfhbkKM The prefix key is an essential part of tmux, by default all of tmux’s key-bindings sit behind a prefix. This prefix is very similar to vim’s leader key. It is common for folks to change the default (control b) to or if they are a vim user something to match their vim leader key. A few of the essential default key-bindings. A more complete list of key-bindings can be found in this gist https://gist.github.com/mzmonsour/8791835.

tmux splitting panes

https://youtu.be/kzgyiHap1nQ splitting panes is a core feature of tmux. It allows us to split the terminal vertically or horizontally into new panes. 🗒️ note that ‘#{pane_current_path}‘will keep the split in the same directory as it’s parent, without this it will default to your home directory.

tmux last session

https://youtu.be/RB87EEnnMnU An ultimate productivity key-binding in tmux is one to switch to the last session. I use this to quickly get between sessions really quick. Often I am working and need to lookup a quick note, or copy something into my notes, then get back to where I was quickly. I think of this hub and spoke model, and use to quickly drive it.

tmux floating popups

https://youtu.be/2ZqFDsJywt8 Tmux popups are actually floating windows that you can drag around the screen. They always open in the middle (by default) when you open them, no matter where you leave them. Here are a couple of keybindings I use to open up popup windows.

tmux popups

https://youtu.be/2I8fB28zfB4 Tmux-popups are a great feature that is relatively new to tmux, many repos such as the standard ubuntu repos do not have it. Popups came in 3.2a, if your package manager does not have it, you can follow the tmux’s install instructions to build from source.

Incremental Versioned Datasets in Kedro

Kedro versioned datasets can be mixed with incremental and partitioned datasets to do some timeseries analysis on how our dataset changes over time. Kedro is a very extensible and composible framework, that allows us to build solutions from the individual components that it provides. This article is a great example of how you can combine these components in unique ways to achieve some powerful results with very little work. What is Kedro 👆 Unsure what kedro is? Check out this post. How does our dataset change over time?? # This was a question presented to me at work. We had some plots being produces as the output of our pipeline and the user wanted the ability to compare results over time. Luckily this was asked early in the project so we were able to proactively setup versioning on the right datasets. To enable this all we needed to do now was to add and we will be able to compare results over time. Yes kedro makes it that easy to setup. set up a project # Set up a new project just as…

Using Kedro In Scripts

With the latest releases of kedro, it is now possible to run kedro pipelines from within scripts. While I would not start a project with this technique, it will be a good tool to keep in my back pocket when I want to sprinkle in a bit of kedro goodness in existing projects. New to Kedro # What is Kedro If your just learning about kedro check out this post walking through it No More Rabbit Hole of Errors # as of 0.17.2 I’ve tried to do this in kedro and it turned into a rabbit hole of errors. First kedro needed a directory, if you tried to fake one in it would then ask for logging setup. These errors just kept coming to the point it wasnt worth doing and I might as well use a proper template for real projects and stick to simple function calls for things that are not a kedro project. Kedro in a script # To get kedro running, you will need a pipeline, catalog, and runner at a minimum. Those who have used kedro before the pipeline will look very similar to what you are familiar with, but…

Silence Kedro Logs

Kedro can have a chatty logger. While this is super nice in production so see everything that happened during a pipeline run. This can be troublesome while trying to implement a cli extension with clean output. Silence a Python log # First, how does one silence a python log? Python loggers can be retrieved by the module’s function. Then their log level can be changed. Much of kedro’s chattiness comes from INFO level logs. I don’t want to hear about anything for my current use case unless it’s essential, i.e., a failure. In this case, I set the log levels to ERROR as most errors should stop execution anyways. python logging levels # Get or Create a logger # Getting a python logger is straightforward if we know the name of the logger. The following block will grab the logger object for the logger currently registered under the name passed in. 🔥 If a logger doesn’t exist under the passed in name, it will create one for you. Set Level # Once we get the logger, we need to silence it by sett…

Python Diskcahe is locked

Running multiple processes using the same diskcache object can cause issues with locks. As I was trying to setup a rich Live display for markata I ran into issues where each part could not nun simultaneusly. As I had followed the instructions from discache it was not directly aparant to me, so I had to make a simple example to experiment and play with at a small scale. Minimum reproducible error # Minimum reporducible error is one of my superpowers in development. I do this very often to sus out what is really happening. My day to day work is processing data with python, I keep a number of very small data sets handy to break and fix. This helps separate complexities of the project and the problem. Let’s break it # Markata has a lot going on. It’s a plugins all the way down static site generator built in python. Trying to find the root cause through the layers of plugin and cli modules can be a pain, but in this case building a very simple minimum reporducible error was much easier. 📝 i…

How I navigate tmux in 2021

In 2021 I changed the way I navigate between tmux sessions big time. Now I can create, kill, switch with ease, and generally keep work separated into logical groups. Update # Since making this post, I have made ~20 other posts in short form that all have a YouTube video to go along with them you can find them all on my tmux-playlist. Chris Toomey’s Tmux Course # I took Chris’s tmux course in December 2020 and it was fantastic. Even as a seasoned tmux user, I learned quite a bit. Before the course, I was proficient in navigating within each of my tmux sessions but rarely started more than one session. A few months later, I have adopted a lot of what I learned from Chris and made it my own. I am now keeping projects to their own session and can move between them fluidly with just a few keystrokes. For high-traffic projects, I have them bound to a single keystroke for instant switching. This change has been a game-changer from the mess of windows I used to have and the nightmare it was to…
