I'm not sure about this. I get what he's saying and agree that singleton methods are nothing but a naming convention for the more fundamental/atomic construct called instance methods (which indeed are the only kind of method that exist in Ruby, depending how you look at it), but I think I would actually say that singleton methods are language concepts because those methods like Object#define_singleton_method, ... are always available in Ruby (without needing to require a standard library first, for example). In other words, I would argue that something belonging in the Ruby core "library" (?) by definition makes it part of the language -- even if it in turn builds on even lower-level Ruby language features/constructs.

You might appreciate the experience from Lynne Kelly here: https://www.lynnekelly.com.au/?p=4794. Her excellent book Memory Craft also has some interesting examples and stories for children including the use of what she calls rapscallions for use in multiplication tables, languages, and other educational applications. Her book also has a wealth of other methods and potential applications depending on the subjects you're teaching.

I'd love to hear your experiences as you progress with your class.

The title of the article immediately made me think of the world we are living in now. For example it is becoming more and more evident that the country has mixed opinions on the vaccine. The government, state agencies and other public entities are requiring proof of a vaccine to even enter the premises. Some companies are offering incentives across the country to incentivize the vaccine by offering free products and discounts. To an extent from a medical perspective you want everyone as healthy as possible, but from a freedom perspective it is on the verge of violating an individual's freedom of choice through forced compliance.

I know that I certainly snuggle doing that.

The Attack on "Critical Race Theory": What's Going on?

https://www.youtube.com/watch?v=P35YrabkpGk

Lately, a lot of people have been very upset about “critical race theory.” Back in September 2020, the former president directed federal agencies to cut funding for training programs that refer to “white privilege” or “critical race theory, declaring such programs “un-American propaganda” and “a sickness that cannot be allowed to continue.” In the last few months, at least eight states have passed legislation banning the teaching of CRT in schools and some 20 more have similar bills in the pipeline or plans to introduce them. What’s going on?

Join us for a conversation that situates the current battle about “critical race theory” in the context of a much longer war over the relationship between our racial present and racial past, and the role of culture, institutions, laws, policies and “systems” in shaping both. As members of families and communities, as adults in the lives of the children who will have to live with the consequences of these struggles, how do we understand what's at stake and how we can usefully weigh in?

Hosts: Melissa Giraud & Andrew Grant-Thomas

Guests: Shee Covarrubias, Kerry-Ann Escayg,

Some core ideas of critical race theory:

• racial realism
  • racism is normal
• interest convergence
  • racial equity only occurs when white self interest is being considered (Brown v. Board of Education as an example to portray US in a better light with respect to the Cold War)
• Whiteness as property
  • Cheryl Harris' work
  • White people have privilege in the law
  • myth of meritocracy
• Intersectionality

People would rather be spoon fed rather than do the work themselves. Sadly this is being encouraged in the media.

Short summary of CRT: How laws have been written to institutionalize racism.

Culturally Responsive Teaching (also has the initials CRT).

KAE tries to use an anti-racist critical pedagogy in her teaching.

SC: Story about a book Something Happened in Our Town (book).

• Law enforcement got upset and the school district
• Response video of threat, intimidation, emotional blackmail by local sheriff's department.
• Intent versus impact - the superintendent may not have had a bad intent when providing an apology, but the impact was painful

It's not really a battle about or against CRT, it's an attempt to further whitewash American history. (synopsis of SC)

Glad this is explicitly mentioned here as it was my initial goal as I got into musical applications of Set Theory!

I seem to recall reading anecdotes of aboriginal peoples who knew areas and water holes in places they'd never visited in their lives. I'm wondering how they may have encoded these in songlines for places they'd never been to and physically seen.

It would seem that it's better to use a physical space when you have access to it, but I don't think I have as much issue adding things to pre-existing palaces/songlines as Kelly describes here. I wonder how this works out for others?

Lynne Kelly is correct here that we need better delineations of the words we're using here.

To some of us, we're taking historical methods and expanding them into larger super sets based on our personal experiences. I've read enough of Kelly's work and her personal experiences on her website (and that of many others) that I better understand the shorthand she uses when she describes pieces.

Even in the literature throughout the middle ages and the Renaissance we see this same sort of picking and choosing of methods in descriptions of various texts. Some will choose to focus on one or two keys, which seemed to work for them, but they'd leave out the others which means that subsequent generations would miss out on the lost bits and pieces.

Having a larger superset of methods to choose from as well as encouraging further explorations is certainly desired.

Anecdotal mention here of someone using sketchnotes or doodling as a mnemonic device.

Sketchnotes could be a means of implementing visual method of loci in one's note taking. Like creating a faux memory palace. Also somewhat similar, expecially in the case of the leaf doodle mentioned above, to the idea of drolleries, but in this case, they're not taking advantage of the memory's greater capacity of imagination to make things even more memorable for long term retention.

Some thoughts about leaving space in new notebooks, especially for one's future self:

• contact information in front in case of loss
• space for a future table of contents to come
• space for page numbers and dates
• space in the back for house keeping, indices, etc.

William Ross Ashby (1903-1972) was a British pioneer in the fields of cybernetics and systems theory. He is best known for proposing the law of requisite variety, the principle of self-organization, intelligence amplification, the good regulator theorem, building the automatically stabilizing Homeostat, and his books Design for a Brain (1952) and An Introduction to Cybernetics (1956).

Funnily enough, I've been on an intellectual bent in the other direction: that we've poisoned our thinking in terms of systems, for the worse. This shows up when trying to communicate about the Web, for example.

It's surprisingly difficult to get anyone to conceive of the Web as a medium suited for anything except the "live" behavior exhibited by the systems typically encountered today. (Essentially, thin clients in the form of single-page apps that are useless without a host on the other end for servicing data and computation requests.) The belief/expectation that content providers should be given a pass for producing brittle collections of content that should be considered merely transitory in nature just leads to even more abuse of the medium.

Even actual programs get put into a ruddy state by this sort of thinking. Often, I don't even care about the program itself, so much as I care about the process it's applying, but maintainers make this effectively inextricable from the implementation details of the program itself (what OS version by which vendor does it target, etc.)

This seems shocking to me.

Class stratification helps to create not only racist policies but policies that enforce the economic stratification and prevent upward (or downward) mobility.

I believe downward mobility is much simpler for Black Americans (find reference to OTM podcast about Obama to back this up).

How can we create social valves (similar to those in the circulatory system of our legs) that help to push people up and maintain them at certain levels without disadvantaging those who are still at the bottom and who may neither want to move up nor have the ability?

Aristotle came up with some solid counter examples against using the principle of sufficient reason and showed how they could be falsified.

Jacobs suggests taking the idea of "walking a mile in another's shoes" to a higher level. He takes Herman Hesse's idea in The Glass Bead Game of the Castalian community's writing a Life in which people write an autobiography about seeing themselves placed in other times/places in history.

Similar examples he includes:

• Flannery O'Connor's story "Revelation" in which a woman chooses being remade as "white trash" or a Black woman.
• Black Like Me by John Howard Griffin (1961)
• White Like Me, a Saturday Night Live skit featuring Eddie Murphy
• Soul Sister by Grace Halsell
• Rachel Dolezal passing as black because she felt it was her identity
• John Rawls' "veil of ignorance"

Jacob suggests this could be a useful exercise for people to attempt, particularly as a senior exercise for university students.

Suppliers with bargaining power can squeeze the profitability out of an industry by raising prices on industry participants that cannot pass on cost increases in their own prices.

Perversely, the author starts off getting this part wrong!

The correct answer here is to adopt the same mindset used for print, which is to say, "just don't worry about it; the value of doing so is oversold". If a print org changed their layout sometime between 1995 and 2005, did they issue a recall for all extant copies and then run around trying to replace them with ones consistent with the new "visual refresh"? If an error is noticed in print, it's handled by correcting it and issuing another edition.

As Tschichold says of the form of the book (in The Form of the Book):

The work of a book designer differs essentially from that of a graphic artist. While the latter is constantly searching for new means of expression, driven at the very least by his desire for a "personal style", a book designer has to be the loyal and tactful servant of the written word. It is his job to create a manner of presentation whose form neither overshadows nor patronizes the content [... whereas] work of the graphic artist must correspond to the needs of the day

The fact that people publishing to the web regularly do otherwise—and are expected to do otherwise—is a social problem that has nothing to do with the Web standards themselves. In fact, it has been widely lamented for a long time that with the figurative death of HTML frames, you can no longer update something in one place and have it spread to the entire experience using plain ol' HTML without resorting to a templating engine. It's only recently (with Web Components, etc.) that this has begun to change. (You can update the style and achieve consistency on a static site without the use of a static site generator—where every asset can be handcrafted, without a templating engine.) But it shouldn't need to change; the fixity is a strength.

As Tschichold goes on to say of the "perfect" design of the book, "methods and rules upon which it is impossible to improve have been developed over centuries". Creators publishing on the web would do well to observe, understand, and work similarly.

Perhaps it's not possible. (Probably not, even.) It would be very much possible to build a web browser capable of handling this page, on the other hand, and to do so in a way that produces an appreciable result in 10 minutes of hacking around with the lowliest of programming facilities: text editor macros—that is, if only it had actually been published as a webpage. Is it possible to do the same for if not just this PDF but others, too? No.

Like the parent comment by derefr, my actual, non-hypothetical practice is saving to the Wayback Machine. Right now I'm probably saving things at a rate of half a dozen a day. For those who are paranoid and/or need offline availability, there's Zotero https://www.zotero.org. Zotero uses Gildas's SingleFile for taking snapshots of web pages, not PDF. As it turns out, Zotero is pretty useful for stowing and tracking any PDFs that you need to file away, too, for documents that are originally produced in that format. But there's no need to (clumsily) shoehorn webpages into that paradigm.

If you do the print-to-PDF workflow outlined earlier in the thread, you'll realize it doesn't scale well, requiring too much manual intervention and discipline (including taking care to make sure it's filed correctly; hopefully you remember the ad hoc system you thought up last time you saved something), that it's destructive, and that it ultimately gives you an opaque blob. SingleFile-powered Zotero mostly solves all of this, and it does it in a way that's accessible in one or two clicks, depending on your setup. If you ever actually need a PDF, you can of course go back to your saved copy and produce a PDF on-demand, but it doesn't follow that you should archive the original source material in that format.

My only reservation is that there is no inverse to the SingleFile mangling function, AFAIK. For archival reasons, it would be nice to be able to perfectly reconstruct the original, pre-mangled resources, perhaps by storing some metadata in the file that details the exact transformations that are applied.

Just like how Betteredge tries to find answer from Robinson Crusoe, Miss Clack is trying to find a solution to this situation from the Correspondence of Miss Jane Ann Stamper.
