I make it a rule to choose my tools carefully and to invest the time to learn them deeply. QEMU has been one of those tools that I've wanted to learn how to use for a long time, but was always a bit intimidated. I actually had been able to use it indirectly via libvirt, but it felt like I was cheating my rule by using one tool to manage another. Despite my vague sense of guilt, things continued this way until I read a recent(ish) introductory post on QEMU by Drew DeVault. The article is well written (as per usual for DeVault), and you'd do well to read it before continuing here. The point is that it was the kick in the pants I needed to finally roll up my sleeves and learn some QEMU.
I love you; you complete me.
I first came to Vim by recommendation. I was looking for a good Python
IDE (at the time I was new to the language) and one recommendation was
to use Vim with a variety of plugins added on top. That Vim could do a
lot of the things I thought only an IDE could do came as a bit of a
shock. I spent a summer as an intern using Emacs at a Unix terminal, but
didn't have enough curiosity at the time to use it any differently from
notepad.exe. I spent that summer wishing I had automatic features for
completion, indentation, and all the things that made me appreciate
the IDE's I used in college. How naive I was!
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:
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.
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.
