The Handbook of Open, Distance and Digital Education, a great (1400+ pages!) resource on elearning has been released as an openly licensed book. Great essays in here on learning theories - I will write more as I get through this, but it looks some of the most interesting writers/researchers on elearning are well represented here. Pay a lot for the print copy or download it free as a pdf. https://link.springer.com/referencework/10.1007/978-981-19-2080-6

I wonder if anyone is documenting the amount of course material that disappears and dies in LMSs the way that some track the loss of data and content when social media silos disappear? Our institutions need to do more to help us here.
McPhee’s Draft No. 4 suggests a useful and fun writing exercise, but it’s missing the hidden contextual advice of using older dictionaries like Webster’s 1913 dictionary.
Encouraging creative writers to keep and maintain a commonplace book is always a fruitful exercise. Most of the “greats” had one (or something close to it), but contemporary examples like Eminem’s may be more relevant/motivating. Blogger and creative writer Austin Kleon has a digital version as an example. Colleen Kennedy has an excellent and creative class assignment relating to this as well.
Musician and producer Brian Eno and artist Peter Schmidt created a set of 100+ “creativity cards” which they entitled Oblique Strategies that can be useful to introduce to students and have them use over a semester. All the editions’ cards can be found via links here: http://www.rtqe.net/ObliqueStrategies/Edition1-3.html, but there are also websites, apps, and even printable cards.
And finally, speaking of cards, it can be fun to do experimental creative writing using index cards, a practice used by Vladimir Nabokov, Jean Paul, Arno Schmidt, Michael Ende, and many others. Open Culture has a short piece on Nabokov’s process.
Should you care to mine it for other possible ideas, I’ve got a digital commonplace of my own. Here are some possible places to start:

POSSE
There are some well built and not overly complicated pathways that allow syndicating from your WordPress website to a Mastodon instance and getting responses back from them, just as I think you’ve done with Twitter in the past. Most of these can be done with plugins like Syndication Links or Mastodon Autopost or a handful of other similar plugins in conjunction with Brid.gy (which does the work for bringing back responses). Personally, I prefer Syndication Links for this and it particularly dovetails well with other IndieWeb infrastructure like Micropub clients.
Mirroring
There are a small handful of methods for “mirroring” your WordPress site so that it will look like its own (single or multi-user depending on your configuration) instance within the Fediverse running ActivityPub, meaning that those on Mastodon or other related platforms could follow your site directly. Most of them are configured as publishing only, so you won’t have a built in reader interface and would have to rely on other (available) infrastructure for those portions.
Option 1
(More technical, and with a few less features) Brid.gyFed, which has options to do the syndication to a separate instance mentioned above, as well as making it look like your website appear to support ActivityPub.
More details on this here: https://indieweb.org/Bridgy_Fed
Option 2
Our friend Matthias Pfefferle, a genius engineer and longtime opensource advocate and WordPress developer who has also written significant pieces of other IndieWeb code you’re already using on WordPress, has written a handful of plugins which will make it appear as if your WordPress site supports ActivityPub out of the box. You’ll broadly want the following plugins: ActivityPub plugin, WebFinger plugin, NodeInfo(2) plugin.
They don’t have very many configurable options though some may be hiding a bit, so try:
/wp-admin/options-general.php?page=activitypubwill give you options for how your posts appear;/wp-admin/users.php?page=activitypub-followers-listwill show you who is following your site so you can more easily subscribe back via a reader if you like;/wp-admin/profile.phpand look under “Fediverse” where your profile identifier will be found. It is based on your username within WordPress.
The documentation for these plugins are scant and I’ve got the intention to write up something explaining the subtleties and a few quirks, but it will have to wait until the holidays I’m afraid. In the interim, they’re not as complete as they could be, but the following two blogposts have some useful details and hints, though its obvious to me that they’re much newer in the space:
- https://odd.blog/2022/11/06/how-to-add-your-blog-to-mastodon/
- https://g13g.blog/2021/03/16/get-your-blog-posts-on-mastodon/
There are one or two quirks still pending for how things display if you’re using the IndieWeb-based Post Kinds Plugin, but the developers are generally aware of most of them and will hopefully get them ironed our shortly.
As a result, mostly of these plugins, WordPress is already the fifth largest number of instances in the Fediverse with an (under-)estimated 878 as of this morning.
I’m practicing both the POSSE option as well as Option 2 above on my own site, which can be followed at @chrisaldrich@boffosocko.com, as an example. Matthias’s example can be found at @pfefferle.
Help & Questions
This is a lot to consume and potentially implement, so, as ever, I’m happy to help guide and lay out the sub-branching options or even hop on a call to walk through bits with folks who have questions. David Shanske and I have been thinking about doing some group sessions and some training videos to walk people through some of this within the next few weeks. There’s also the IndieWeb chat which welcomes questions and conversation which is sure to give you some additional perspective: https://chat.indieweb.org/wordpress/.
For the social reader portions I briefly mentioned, I outline some of those options last year at OERxDomains in A Twitter of Our Own.
HCommons
Separately, congratulations to HCommons having stood up a Mastodon server so quickly!
It looks like it’s running Hometown, which has local only (unfederated) posting, though I’m not sure how many are aware of that useful feature (hiding on the link in the posting interface) which is sadly missing from most Mastodon instances, particularly for smaller communities. It might be something useful to add to the welcome email? I think this could be a great feature for Universities to allow more private class-based social networking while providing some safer spaces that don’t reach the broader internet and which might comply with FERPA. Obviously it would need some testing and some of the barriers for standing up and maintaining these servers to come down a bit.
There’s a lot of messaging and potential education to be had to roll it out well, but it could be interesting to see the WordPress offerings from hcommons.org include some of these IndieWeb and Fediverse tools as well.

Theory and Applications of Continued Fractions MATH X 451.50 | Fall 2022
For almost 300 years, continued fractions—that is, numbers representable as the sum of an integer and a fraction whose denominator is itself such a sum—have fascinated mathematicians with both their remarkable properties and their myriad applications in such fields as number theory, differential equations, and computer algorithms. They have been applied to piano tuning, baseball batting averages, rational tangles, paper folding, and plant growth … the list goes on. This course is a rigorous introduction to the theory and mathematical applications of continued fractions. Topics to be discussed include quadratic irrationals, approximation of real numbers, Liouville’s Theorem, linear recurrence relations and Pell’s equation, Hurwitz’ Theorem, measure theory, and Ramanujan identities.
Mike is recommending the Continued Fractions text by Aleksandr Yakovlevich Khinchin. I found a downloadable digital copy of the 1964 edition (which should be ostensibly the same as the current Dover edition and all the other English editions) at the Internet Archive at Based on my notes, it looks like he’s following the Khinchin presentation fairly closely so far.
If you’re interested, do join us on Tuesday nights this fall. (We’ve already discovered that going 11 for 37 is the smallest number of at bats that will produce a 0.297 batting average.)
