Fountain Pen Vocab: Attenuate

For a while I've been hunting for the right word to describe the difference between the super smooth nib grinds of the pens that I've used from Pilot and the nibs from Platinum and Sailor, both of which have feedback. Most people focus on that feedback, with the conclusion usually

Co-dfns support for very large arrays!

Previously, Co-dfns could only support ranks <= 4. Now, the architecture supports arbitrarily large array sizes, though this is only partially used in various primitives. See the release notes for more details. However, this is a bigger deal than it might seem, as it opens up a number of new

Understanding the High Performance Planner by Brendon Burchard

A few years ago, famous personal development personality Brendon Burchard released his High Performance Planner. As popular as it is, many of the reviews seem to miss the point. The biggest fault I notice is in understanding how to use it and why it might make sense for you as

A little bit of Black vs. Blue Fountain Pen philosophy

I've been doing some permanent ink tests of various types of inks, and without a doubt, the black, pigmented inks are coming out decidedly on top. I've been using Platinum Carbon ink for a while because it is one of the best, most durable, enduring inks you can get. It's

Productivity Systems: Bullet Journaling

As previously noted, I tend to look for productivity systems that are total and holistic. I'm also willing to criticize them for my purposes at least on ostensibly rigorous or thorough grounds (other than "effort" or "effectiveness"). The 3 major ones I have spent the most time with are Bullet

If some of my handwritten blog entries seem to be written with a different pen and a different style, it's because I'm experimenting with a new type of handwriting, Italic.

Configuring your APL keyboard on Linux

Writing code to be spoken

A personal favorite design element that APL allows me to explore is the "lyricality" of a given piece of code. I ask myself how much the natural language description of what a piece of code does would map directly to the code. This is a sort of discussion that simply
