Zsh Compinit ... RTFM

This week I dealt with a problem that had been bugging me. I noticed that the time a took to start a new Zsh terminal session went from essentially instant to around 4 seconds [1]. I take some pride in running a lightweight system, so the thought of having to wait a few seconds for my terminal emulator to display a prompt feels like a personal affront. My system wasn't just behaving badly, it was challenging me by way of insult.

Accepting the challenge laid before me, I took to my favorite search engine to see what tools were available to help me understand what was suddenly performing so poorly. Oh, okay. This post says that Zsh includes a script profiler. All I need to do is turn it on in my .zshrc file, like so:

Getting Started On Mastodon

If I've identified a trend in my social media preferences, it's that I prefer not to use social media. That's not to say that I don't use it, just that I often feel conflicted when I do. On the one hand, this is where my friends are, and online networks have become a sort of pseudo-public square. (My choice of words there is deliberate ... "pseudo" as in "fake." I actually don't think online networks work as a true replacement for a public square, but that's a post for another time.) Skip out on social media altogether and you basically opt-out of a lot of opportunities to rub elbows with people, which, despite all of the good and the bad that entails, I still think is worthwhile.

On the other hand, popular social networks are for-profit companies that invariably make their money by turning their users into their product, which is packaged and sold to online advertisers. I don't know about you, but to me that feels a bit dehumanizing. Sure, that model of business existed long before social networks did, at least in the abstract, but let's not kid ourselves—the way we're packaged and sold to advertisers is far different in the hands of social networks than at any time in history. Magazines and television networks could guess at the kinds of readers and viewers they attracted, and companies like Nielson could even provide some hard data to back up their guesswork, but what they didn't have was gobs of very personal data from which to draw conclusions about us. Apart from our reading/viewing habits, older forms of media had comparatively little to work with.

New Website Backend

For those interested, I've converted this website over from a Django backend to Nikola. Since there aren't any interactive features on this site, it's clear that an engine such a Django was overkill and that Nikola's static generator was a better option. So far, so good. I especially being able to choose a templating engine (I went with Jinja, since it was most like Django's templating engine).

If you notice anything weird or broken with the site, please hit me up on one of the social media links on the landing page.

Cheers!

Hardening Services With Systemd

Systemd gets a lot of hate. There's a lot of heat and very little light in those discussions, in my opinion, and I don't expect that this post will change the mind of anyone who has already decided to hate Systemd. My goal here is far more modest. I want to share a feature of the new init system that I find really compelling, and that I hadn't seen discussed pretty much anywhere: Systemd's native ability to leverage the Linux kernel's namespacing features to run services in a sandboxed environment.

A Letter To Senator Rubio

Senator Rubio,

As a registered Republican, a citizen of the state of Florida, and an evangelical Christian, I have watched with a mix of anger and horror as our President has subverted the core values this party has stood for and abused high office what appears to be his own selfish gain. Over the past several weeks that mix of emotions has been replaced by heartbreak as his administration has enacted, and then defended, a set of policies that have directly resulted in the separation of children from their parents. As both a seminary graduate and an ordained church elder, it brings additional pain to see that that the Bible, the same Scripture this party has used to defend "family values," has been perverted to defend practices that are the antithesis of that phrase.
