Updated 03-Aug-2025 Update early 2021 - Apparently ChromeOS outsold OSX in 2020. This makes sense as the strength of the ChromeOS is primarily in the education market, and that market exploded with demand because of Covid-19 school closures and the need for devices for remote schooling. This is an overview of what Chromebooks, Chromeboxes, and ... Read more

Updated 03-Aug-2025 A site called Living Montessori is a prime example of the kind of nonsense that goes by the name of Montessori Inspired. This site is particularly pernicious because the author claims legitimacy by having been a Montessori teacher and school director. The fact that the Montessori training was in the UK, which only ...

Updated 03-Aug-2025 Dropbox is a cloud storage and sync service, with additional editors/apps, such as Paper and Showcase. For various reasons, those additional Dropbox apps are not useful for our use cases. However, storage and sync are excellent in and of themselves, and generally superior to Google Drive which is the only real alternative. What ... Read more
Updated 03-Aug-2025 Dropbox Paper is a product I really want to like. For one thing, the promise of better editor is something long unfulfilled. And taking some design cues (or perhaps merely unrelated similarities), Medium did do something nice for the blogging environment. By extending it as essentially a wysiwyg Markdown+ editor, drag and drop-friendly, ... Read more
Updated 03-Aug-2025 We can call this Tsuite, inspired by Toot Sweet (a Chitty Chitty Bang Bang candy invention), and is meant to provide some functionality offered through third party collaborative documents. The main point is to have a self-hosted, free-and-open-source alternative, albeit with more bare bones functionality. Ultimately the goal is to be functional enough ... Read more
Updated 03-Aug-2025 AWS DHCP options are set on a per-VPC (Virtual Private Cloud) basis. By default, things like the search scope and DNS servers used by a given AWS Instance are set by DHCP which also provides the private IP address (but not any Elastic IP Addresses). Indeed, the Amazon Virtual Private Cloud is a ... Read more

Updated 03-Aug-2025 What is Montessori? I am a great fan of Maria Montessori and her ideas about education. That said, she is long-dead and the Montessori we have is not her ideas (though we do have her books) but rather a set of institutions, schools, and teachers. We must look closer to see clearly. Because ... Read more
Updated 03-Aug-2025 A big part of speed is managing the browser cache. This usually means setting compression (gzip/deflate) and expirations of cached content. Compression takes place at the web server (generally after minification). Minification usually also combines files together, so that that there are fewer requests. Compression provides enormous advantages (much more than minification), however, ... Read more
Updated 03-Aug-2025 MySQL is good for large multi-user databases. However, when dealing with few changes to the database, and many reads, it is far from a great solution (in fact, is a terrible solution). SQLite is far superior in that situation, and for serial/sequential edits. MySQL 5.6 vs. 5.7 For those with minimal database needs, ... Read more
