Problem: I need just one literal underscore in my org-exported blog post I export orgmode to my blogs. However, when I have an underscore (like in a section header) it is interpreted as putting the next thing in a subscript. There are plenty of answers out there for disabling this globaly or for the whole file, but I WANT subscripts sometimes. How do I tell it to leave just a particular _ alone when I export?

Intro I used to have an exwm emacs shortcut to change my volume: (exwm-input-set-key (kbd "<XF86AudioLowerVolume>") (lambda () (interactive) (shell-command "amixer set Master 2%-"))) and a similar function for the volume-up key. When I press the audio buttons, it uses amixer to change the volume. The trouble is, guix doesn’t seem to offer amixer anywhere. I don’t see it in nongnu packages, so I was able to find pactl instead. Here’s how I got it (improvement suggestions welcome):

Intro A recent stack overflow question asked about Clojure performance compared to other implementations, with Python and raw java performing vastly better than Clojure1. Now, this is Clojure, so there must be a better way. One of the answers pointed to RosettaCode and Clojure fibonacci implementations there2, so I felt pretty good grabbing the “Doubling Algorithm (Fast)” version given there, which is based on an off-the-cuff github answer from Clojure optimization guru Mike Fikes3.

Intro Installing things on guix is usually more involved that just using the one-liners you may have been given with other things in mind. Getting NPM in Guix Install the latest node to get the npm command. guix install node

The command Sometimes I started a command with a java -jar mything.jar & long ago, and now it needs to be updated, and I haven’t got around to properly instrumenting it yet. Here is the command that helps me find and shutdown the old process so I can restart it. ps -ef | grep mything Resources https://community.talend.com/s/article/How-to-find-and-kill-a-process-running-on-a-port-LVJkZ?language=en_US#auraLoadingBox

Intro I upgraded orgmode recently and added org-contrib to my loading. I’m not sure if that’s related or not, but suddenly, when I invoke org-capture on a Gnus message (which used to happen seamlessly, suddenly I am getting the following selection message, asking me whether I want org-mairix-store-gnus-link or the old working default org-gnus-store-link . This is the first time I have ever heard of Mairix, and I can’t find any customizations to set to get it to stop asking me.

Intro I use Firefox Mobile, which tries to install the PWA (Progressive Web App) of sites whenever it finds a manifest file; otherwise it allows installation to just add a Firefox link to the site instead, which is what I want. This can be done with the Ublock plugin1. I’m struggling to find the right syntax for this; I believe I want a static filter that applies to any site. An example of the line that brings the manifest from Google Photos is this:

Intro Sometimes in EXWM when I switch machines to and plug in my dock to an already running system, one or two of my external monitors stay black1. Sometimes this also occurs when my smart-dock2 changes power levels to the dock. It has enough throughput to utilize my whole 100w power inlet, but its “smarts” mean that when I connect my USBC phone, for instance, the amount of power going out changes dramatically and the shift can “lose” my two HDMI monitors until I do the trick below.

Don’t do webdev work in your personal browser account Opening dev sites in your primary browser/account is problematic. Opening in Private (FireFox) or Incognito (Chrome) is a must, since it usually turns off caching and removes you from any left-over accounts that might be interfering with your validation. I’ve always done dev sites in my dev browser, so good to hear a group that recognized (sort of) this: https://polypane.app/blog/always-open-localhost-in-your-development-browser/ And disclaimer: Polypane who wrote the article is a paid browser (after 2 weeks).
