To run a little project (that I’ll describe at some point in the future) I have to run a small web server from my home computer, one that happens to run macOS. More than anything else, this is just a reply of what I did to get it running in case: a) I have to do it again, or b) Someone else can find it useful. Sign up for dynamic DNS service I signed up for service with dynv6 because I saw it recommended elsewhere and it didn’t look creepy like some of the other options.
Maybe I’m just getting cranky after over a year of on-again-off-again pandemic lockdowns, but I’ve had it with Apple’s heavy-handed attempts to get me to upgrade to Big Sur. Mind you, I have nothing against it. It’s just an operating system. I don’t particularly like it’s translucent bubbly iOS look. But I could live with. But I don’t want it. I depend on a very unorthodox setup. I have a lot of infrastructure tools that depend on certain versions of Python to be in just the right place.
Custom aliases in oh-my-zsh With oh-my-zsh, you can store custom aliases in multiple (?per application) file under .oh-my-zsh/custom giving them .zsh file extensions.1 ¶For example, in my hugo.zsh file, I have: alias hnewtil="/Users/alan/Documents/blog/ojisan/scripts/newtil.sh" alias gtojisan="cd /Users/alan/Documents/blog/ojisan; ls -l;" Executing inline Python in a shell script It’s possible using the -c command.2 python -c 'import foo; foo.bar()' https://scottwhittaker.net/posts/oh-my-zsh-custom-aliases/ ↩︎ https://stackoverflow.com/questions/16908236/how-to-execute-python-inline-from-a-bash-shell ↩︎
While Russian text intended for native speakers doesn’t show accented vowel characters to point out the syllabic stress (ударение) , many texts intended for learners often do have these marks. But how to apply these marks when typing? Typically, for Latin keyboards on macOS, you can hold down the key (like long-press on iOS) and a popup dialog will show you options for that character. But in the standard Russian phonetic keyboard it doesn’t work.
Having fallen in love with Keyboard Maestro for its flexibility in macOS automation, I began experimenting with scripting in various languages, like my old favourite Perl. That’s when the fun began. How do we access KM variables inside a Perl script. Let’s see what the documentation says: So the documentation clearly states that this script #!/usr/bin/perl print scalar reverse $KMVAR_MyVar; should work if I have a KM variable named MyVar. But, you guessed it - it does not.
sed is such a useful pattern-matching and substitution tool for work on the command line. But there’s a little quirk on macOS that will trip you up. It tripped me up. On most platforms, \s is the character class for whitespace. It’s ubiquitous in regexes. But on macOS, it doesn’t work. In fact, it silently fails. Consider this bash one-liner which looks like it should work but doesn’t: # should print I am corrupt (W.
Since I’m not fond of carrying around all my photos on a cell phone where they’re perpetually at list of loss, I peridiocally dump the image and video files to a drive on my desktop for later burning to optical disc.1 Saving these images in archival form is a hedge against the bet that my existing backup system won’t fail someday. I’m using Blue-Ray optical discs to archive these image and video files; and each stores 25 GB of data.
macOS offers a variety of virtual keyboard layouts which are accessible through System Preferences > Keyboard > Input Sources. Because I spend about half of my time writing in Russian and half in English, rapid switching between keyboard layouts is important. Optionally in the Input Sources preference pane, you can choose to use the Caps lock key to toggle between sources. This almost always works well with the exception of Anki.
One of the sites that I manage uses a jQuery-based image gallery to display images in a grid. The script decides which thumbnail to use based on how large and image is needed. A series of suffixes à la Flickr^[Well, sort of. I don’t think this is exactly what Flickr uses; and I made up the _q suffix for the less than 500px image.] is used to signify classes of image size.
