There’s a phenomenon that verteran Anki users are familiar with - the so-called “Anki hell” or “ease hell.”

Origins of ease hell

The descent into ease hell has to do with the way Anki handles correct and incorrect answers when it presents cards for review. Ease is a numerical score associated with every card in the database and represents a valuation of the difficulty of the card. By default, when cards graduate from the learning phase, an ease of 250% is applied to the card. If you continue to get the card correct, then the ease remains at 250% in perpetuity. As you see the card at its increasing intervals, the ease will remain the same. All good. Sort of.

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. Hold down the e key and you’ll get the option for the letter ë (yes, it’s regarded as a separate letter in Russian - the essential but misbegotten ë .)

While largely opaque to most users, Facebook and Google massage any links that you acquire on their sites to include data used to track you around the web. This script attempts to strip these surveillance parameters from the URL’s. It is by no means all-inclusive. Imaginably, there are links that I haven’t yet encountered and that need to be considered in a future version. So consider this a proof-of-concept.

The problem

For example, I performed a Google search¹ for “Smarties”. Inspecting the first link - to Wikipedia, I see:

Predictions for 2021

Humans are notoriously poor at assigning probabilities to events, even those that are highly relevant to their daily lives. This year I’m making a deliberate attempt to calibrate my prediction abilities by correlating predictions with reality. The judgments of truth of these outcomes will be made on December 31, 2021, although some of the outcomes will have been decided substantially in advance of that.

As part of a Hazel rule to process downloaded mp3 files, I worked out a couple different methods for extracting the ID3 title tag. Not rocket science, but it took a little time to sort out. Both rely on non-standard third-party tools, both for parsing the text and for extracting the ID3 tags.

Extracting ID3 title with ffprobe

ffprobe is part of the ffmpeg suite of tools which on macOS can be installed with Homebrew. If you don’t have the latter, go install it now; because it opens up so many tools for your use. In this case, it makes ffmpeg available via brew install ffmpeg.

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.

Justification

Although caching can make page loads notably faster, it comes with a cost. Browsers aren’t always capable of taking note when a cached resource has changed. I’ve noticed recently that Safari utterly refuses to reload .css files even after emptying the browser cache and clearing the web history.

Background

With a lot of help from the a pair of articles written by Ukiah Smith, I’ve developed a workflow for dealing with this problem during the deployment process. He describes two approaches to the problem of static asset caching, one an improvement on the other. I’ve implemented something like what he describes using the git file hash to modify the filename of the css files. When the client browser sees a new filename, it always reloads the resource. So the problem is to figure out how to only change the filename when the contents have changed. Let’s say you tweak a css parameter and want to ensure that client browsers load the correct version. We can use the git file hash, and append it on the filename. Then the only remaining problem is to make sure that the page head template knows how to find the correct version to bake into the pages. Here, our approach is the same as Smith’s.

Justification

Last week I outlined my evolving comprehensive approach to thwarting surveillance capitalism - that is the extraction, repurposing and selling of online behavioural surplus for the purposes of altering future behaviour.

This is a simple iOS shortcut to the embedded Safari setting for clearing Safari history and website data. It turns out that when iOS Safari is presented with a URL in a certain format, it will execute preference settings on the device. After a little trial and error, I noted that the setting Settings → Safari → Clear History and Website Data has its own URL: prefs:root=SAFARI&path=prefs:root=SAFARI&path=CLEAR_HISTORY_AND_DATA. By loading that URL through an iOS Shortcut, you can quickly sanitize iOS Safari.
