Updated 03-Aug-2025 The original formulation of Zipf's law was based on naturally occurring word frequencies and their rank order in a given English language corpus. For one example, merely 135 words accounted for 50% of the total word frequencies. This could be extended to phrases as well. For foreign language learners, this means that there ... Read more
Updated 03-Aug-2025 On January 1, 2009 CNN published an article on memory. Now would be a good time to review and expand on that article, in the hopes of improving our own memory. It may be useful to conceive of the Art of Memory as having four broad application areas, a set of techniques (often ... Read more
Updated 03-Aug-2025 Necessity being the mother of invention, what if a densely populated, but small (~10m) country were to have zero access to petroleum for fertilizer and agriculture in general? Sustailable Agriculture would be a result (or starvation). What if Sustainable Agriculture Weren't Theoretical? The Case of Cuba Cuba's Agrifood System in Transition How to ... Read more

Updated 03-Aug-2025 It is a good idea to get PHP and MariaDB on Debian set up before Nginx (except the PhpMyAdmin which can come after).

Updated 03-Aug-2025 The thing about history is that there is a lot of it. And prehistory, well, so much more. The highlights: carbon/methane sequestration 50mya seas and temperatures Return of the wooly mammoth Arctic resources Emigration for the next 1,000 years O Canada Paleocene-Eocene Thermal Maximum (PETM) > At least since 1997, the Paleocene–Eocene Thermal ...

Updated 03-Aug-2025 Google likes to remove functionality on free products to induce upselling. This is a common tactic in many software/SAS models. However, the cost of adopting Gsuite is very high, relative to free. Essentially a 5-10 pack of mailboxes with $5/month for the least expensive Gsuite paid option. That's $300-$600/year. What is sadly missing ... Read more
Updated 03-Aug-2025 By Amazon Canada, I am referring to the Amazon Advantage Canada operation. Pure, unadulterated incompetence. Support requests go something like this: - Me: Here is my problem, with detail - AC: Request for information (which is already in the detail) - Me: Submission of requested info, again - AC: Thank you, please wait ...

Updated 03-Aug-2025 Note: I've replaced Fish Shell with Bash in my personal technology stack, as of March 2018. Ha ha, back on Fish Shell. Fish Shell is a very useful shell. I use it on OSX and Linux. Provides for some sanity at the command line. For an editor I use Nano. Note that there ... Read more
Updated 03-Aug-2025 Bash being the most common shell, it makes sense to learn bash shell scripting. I didn't think this at first and later came to the conclusion, having spent time with Fish Shell. However, Bash is definitely old and creaky with some frankly ridiculous implementation details. Fish can be installed most everywhere, and is ... Read more
Updated 03-Aug-2025 Here are some ways of getting things tweaked. Your mileage may vary. Mint-Y-Dark This theme has some hardcoded colors in PNG files. Grayscale them with ImageMagick, as follows: for file in /usr/share/themes/Mint-Y-Dark/gtk-2.0/assets/*.png; do convert "$file" -colorspace Gray "$file"; done for file in /usr/share/themes/Mint-Y-Dark/gtk-3.0/assets/*.png; do convert "$file" -colorspace Gray "$file"; done Edit the /usr/share/themes/Mint-Y-Dark/gtk-2.0/gtkrc ...

Updated 03-Aug-2025 Scrollbar usability is shoddy and slipping across wide swaths of the web and software in general. Of course I am getting older, which means this is more and more of an annoyance. We know already, and for some time, how to do scrollbar usability and accessibility. Putting aside voice commands, just the bare ... Read more

Updated 03-Aug-2025 This is a setup of several items, starting with Debian 9 on Amazon AWS Lightsail. This has server basics and apt, and then follows with links to additional articles. In general, after several years of running CentOS on Linode, and then Amazon Linux AMI on EC2 and Lightsail, I find that Debian 9 ... Read more
Updated 03-Aug-2025 Well, it turns out, there is no such thing, per se, as an IPA Keyboard Layout, at least not in the sense that there are keyboard layouts for various languages and layout styles (e.g., English, Dvorak, etc.). This seems to me to be a tremendous oversight, though it obviously came about because someone ... Read more

Updated 03-Aug-2025 Note: since Debian has Cinnamon built-in as a desktop choice on install, and since the rest of Mint is Ubuntu or Debian (LMDE), it seems a bit nonsensical to go Mint when I can go Debian +Cinnamon.
