My Emacs setup for Org mode, flyspell, and git

Originally posted June 2, 2018


I do much of my work in SSH shells to remote servers and while I have used Emacs for about 30 years I don’t usually take too much time and effort customizing it. I have recently started using Org mode at work (I am a Master Software Engineer at Capital One and manage a Deep Learning team) and at home. Today after enjoying a Saturday morning gym workout I decided to improve my Emacs setup and this blog article is documentation that I will use in the future for reference. If it saves you some time or gives you useful ideas, even better!
I wanted to enable flyspell (which is installed with any current Emacs distribution) for all text modes, and that includes Org mode files. I added the following to my .emacs file:
(add-hook 'text-mode-hook 'turn-on-visual-line-mode)

;; flyspell                                                                                                   
(dolist (hook '(text-mode-hook))
  (add-hook hook (lambda () (flyspell-mode 1))))
I like to augment the Aspell spelling dictionary with words I commonly use that are not in the default dictionary. As an example, I am going to configure Aspell with a custom dictionary and add the word “Keras” and “TensorFlow: by creating a file ~/.aspell.en.pws that contains:
personal_ws-1.1 en 0
Keras
TensorFlow
Now when your local Emacs runs Aspell, flyspell will pick up the words in your custom dictionary.
I love Org mode, especially with SrSpeedBar, to quickly navigate and use Org to organize my day, take project notes, etc.
I like to use SrSpeedbar when in window mode (i.e., when running Emacs locally in its own window) but not inside a terminal or SSH session. I add the following to my .emacs:
(load "~/.emacs.d/sr-speedbar.el")
(require 'sr-speedbar)
(setq
    speedbar-use-images nil
    speedbar-show-unknown-files t
    sr-speedbar-right-side t)
(when window-system
  (sr-speedbar-open))
(setq sr-speedbar-width 40)     ;; doesn't work for me
(setq sr-speedbar-max-width 50) ;; doesn't work for me
I usually run package-list-package to find and install Emacs packages but I load sr-speedbar.el from a downloaded source file.
I sometimes use magit for using git inside my Emacs environent but I usually just run git on the command line.
Magit is probably already installed with your Emacs but if not you can use package-list-package (or however else you manage Emacs packages) to instal it.
So far I have not customized my magit setup at all, not even any key bindings. I use M-x magit- followed by the tab character to see possible completions. Usually I just use M-x magit-status to review version histories. Magit is a deep tool and I am getting used to it slowly, learnig features as I need them.

My Dad's work with Robert Oppenheimer and Edward Teller

Robert Oppenheimer and Edward Teller facilitated my Dad getting a professorship at UC Berkeley when I was 3 years old. Oppenheimer left Berkeley but Teller was a good friend of my father and I remember him being in our home. Three weeks ago, my wife and I were just leaving to see the new Oppenheimer movie when my Dad called. He mentioned that when I was in grade school he was invited to give a talk at Princeton. After his talk Oppenheimer talked with my Dad and invited him to have dinner at his house. My Dad said Oppenheimer was not well (I think he died of throat cancer soon afterwards) but his wife Kitty carried the conversation. My Dad, Ken Watson, passed away 10 days ago on August 18, 2023.

Time and Attention Fragmentation in Our Digital Lives

  As humans we have evolved over a few million years to be both attentive and reactive to danger, live in social communities, and spend much of our time being in the present moment gathering and eating food and socializing. The behavior of rapidly changing short attention to content on social media, too many good short form things to watch on streaming video entertainment platforms, are all rewiring our brains in an unnatural and unhealthy way. I fight back, but in really simple ways that entail little ceremony: Almost every morning I spend 30 minutes scanning Hacker News (about 10 minutes), Apple News (about 5 minutes), and the remaining time on Twitter and Mastodon finding interesting new (mostly tech) things. I make notes in a temporary Apple Note: links of things I may want to research, try, or simply read that day. I like to get this all done at once, and then not feel like I need to interrupt my activities during the day to “catch up” on what is happening in the world. In a w...

I am moving back to the Google platform, less excited by what Apple is offering

I have been been playing with the Apple Intelligence beta’s in iPadOS and macOS and while I like the direction Apple is heading I am getting more use from Google’s Gemini, both for general analysis of very large input contexts, as well as effective integration my content in Gmail, Google Calendar, and Google Docs. While I find the latest Pixel phone to be compelling, I will stick with Apple hardware since I don’t want to take the time to move my data and general workflow to a Pixel phone. The iPhone is the strongest lock-in that Apple has on me because of the time investment to change. The main reason I am feeling less interested in the Apple ecosystem and platform is that I believe that our present day work flows are intimately wrapped up with the effective use of LLMs, and it is crazy to limit oneself to just one or two vendors. I rely on running local models on Ollama, super fast APIs from Groq (I love Groq for running most of the better open weight models), and other APIs from Mist...
