We must not use the word system, then, to refer to an object. A system is an abstraction. It is not a special kind of thing, but a special way of looking at a thing.
-
In order to speak of something as a system, we must be able to state clearly: (1) the holistic behaviour which we are focusing on; (2) the parts within the thing, and the interactions among these parts, which cause the holistic behaviour we have defined; (3) the way in which this interaction, among these parts, causes the holistic behaviour defined. If we can do these three, it means we have an abstract working model of the holistic behaviour in the thing. In this case, we may properly call the thing a system, If we cannot do these three, we have no model, and it is meaningless to call the thing a system.

How to fold and cut a Christmas star<br /> Christian Lawson-Perfect https://www.youtube.com/watch?v=S90WPkgxvas
What a great simple example with some interesting complexity.
For teachers trying this with students, when one is done making some five pointed stars, the next questions a curious mathematician might ask are: how might I generalize this new knowledge to make a 6 pointed star? A 7 pointed star? a 1,729 pointed star? Is there a maximum number of points possible? Is there a minimum? Can any star be made without a cut? What happens if we make more than one cut? Are there certain numbers for which a star can't be made? Is there a relationship between the number of folds made and the number of points? What does all this have to do with our basic definition of what a paper star might look like? What other questions might we ask to extend this little idea of cutting paper stars?
Recalling some results from my third grade origami days, based on the thickness of most standard office paper, a typical sheet of paper can only be folded in half at most 7 times. This number can go up a bit if the thickness of the paper is reduced, but having a maximum number of potential folds suggests there is an upper bound for how many points a star might have using this method of construction.

Certainly you could adapt the code to round rather than truncate should you need to; often I find truncation feels more natural as that is effectively how clocks behave.
What do you mean exactly? Compared clocks, or at least reading of them. What's a good example of this? If it's 3:55, we would say 3:55, or "5 to 4:00", but wouldn't probably say that it's "3".

Web sites often design their APIs to optimize performance forcommon cases. Their main object-reading methods may return onlycertain “basic” properties of objects, with other methods availablefor fetching other properties. ShapirJS hides this performanceoptimization complexity from the user.
In other words, it risks undermining the intent of the API design.

The value of <Y>, the position of which varies in the sequences, may be the precursor of place value, in which, for example, 5, 50 and 500 represent different values according to their position, thought to have been a Sumerian invention (d'Errico et al. Reference d'Errico, Doyon and Colage2017).
The idea of place value is thought to have been a Sumerian invention (d'Errico et al., 2017), but the example of <Y> in the work of B. Bacon, et al (2023) may push the date of the idea of place value back significantly.

We believe that we have demonstrated the use of abstract marks to convey meaning about the behaviour of the animals with which they are associated, on European Upper Palaeolithic material culture spanning the period from ~37,000 to ~13,000 bp. In our reading, the animals integral to our analytical modules do not depict a specific individual animal, but all animals of that species, at least as experienced by the images’ creators. This synthesis of image, mathematical syntax (the ordinal/linear sequences) and signs functioning as words formed an efficient means of recording and communicating information that has at its heart the core intellectual achievement of abstraction.

I came to this page after reading the "About the Author (The Second Right Answer)" page of Roger von Oech's "A Whack on the Side of the Head: How You Can Be More Creative" which was mentioned by Kevin Bowers in his discussion with John Vervaeke titled "Principles & Methods for Achieving a Flow State | Voices w/ Vervaeke | John Vervaeke & Kevin Bowers".
von Oech stated that
I wrote my doctoral dissertation on the twentieth century German philosopher Ernst Cassirer, the last man to know everything. From him, I learned that it's good to be a generalist, and that looking at the Big Picture helps to keep you flexible.
This was a surprising reference since Bowers stated that the book was written for helping entrepreneurs become more creative; the book seems more widely applicable based on the examples and exercises given in the first 20 pages.
Cassirer appears to bridge between the continental and analytic traditions in philosophy. Cassirer's touching on mathematics, aesthetics, and ethics reminds me of - John Vervaeke's work - ie, the process of relevance realization and his neo platonic, transformational reading of ancient texts - Forrest Landry work - ie, his magnum opus "An Immanent Metaphysics" which he purports to be pointing to a foundation between ontology, epistemology, and ethics. Recently, IDM (Immanent Domain Metaphysics) made more sense to me when I attempted to translat the 3 axioms and 3 modalities into language from category theory
The following seem important and related somehow: 1. the symbolic process 2. the process of abstraction 3. the process of representation
Maybe these are related to the means by which one can can transcend their current self? ie, is it through particular symbolic practices that one can more easily shed one identity and acquire another?
Also, are 1., 2., and 3. different aspects of the same thing/event?

Testing frameworks often introduce their own abstractions for e.g. evaluation order, data validation, reporting, scope, code reuse, state, and lifecycle. In my experience, these abstractions are always needlessly different from (and inferior to) related abstractions provided by the language itself.

NB: the requirement wasn't actually "parsing JSON in C"; it's that for the JSON parsing the machine ultimately executes the same (or similar) instructions that it does when the JSON parsing is written in C and that C is compiled with GCC.

here are several ways I havefound useful to invite the sociological imagination:
C. Wright Mills delineates a rough definition of "sociological imagination" which could be thought of as a framework within tools for thought: 1. Combinatorial creativity<br /> 2. Diffuse thinking, flâneur<br /> 3. Changing perspective (how would x see this?) Writing dialogues is a useful method to accomplish this. (He doesn't state it, but acting as a devil's advocate is a useful technique here as well.)<br /> 4. Collecting and lay out all the multiple viewpoints and arguments on a topic. (This might presume the method of devil's advocate I mentioned above 😀)<br /> 5. Play and exploration with words and terms<br /> 6. Watching levels of generality and breaking things down into smaller constituent parts or building blocks. (This also might benefit of abstracting ideas from one space to another.)<br /> 7. Categorization or casting ideas into types 8. Cross-tabulating and creation of charts, tables, and diagrams or other visualizations 9. Comparative cases and examples - finding examples of an idea in other contexts and time settings for comparison and contrast 10. Extreme types and opposites (or polar types) - coming up with the most extreme examples of comparative cases or opposites of one's idea. (cross reference: Compass Points https://hypothes.is/a/Di4hzvftEeyY9EOsxaOg7w and thinking routines). This includes creating dimensions of study on an object - what axes define it? What indices can one find data or statistics on? 11. Create historical depth - examples may be limited in number, so what might exist in the historical record to provide depth.

I avoided using languages that I don't know how to bootstrap like node.js
There's a weird (read: "weirdly obvious") category error here. NodeJS is not a language. (This wouldn't be so notable if the comment didn't go on to say "The key point is writing to an interface and not an implementation.")
The puzzle piece that fits the shape of the hole here is "JS". JS is the language, NodeJS is one of its implementations—and chubot knew both of these things already, so it's odd that it was expressed this way. Plus, there's a lot more diversity of JS implementations than exist for e.g. Python...

Even physicists,when they leave equations behind and try to describetheir discoveries to the rest of us in plain English, findthemselves employing analogies, metaphors, and theother language tools we all use
Within mathematical contexts one of the major factors often at play is the idea of abstraction: how can one use a basic idea and then abstract it to other situations to see what results.
The idea of abstraction in mathematics is analogous to analogy and metaphor in literature.

Consider, as well, the extent to which the tools of abstraction are themselves tied up in the history of the trans-Atlantic slave trade. As the historian Jennifer L. Morgan notes in “Reckoning With Slavery: Gender, Kinship, and Capitalism in the Early Black Atlantic,” the fathers of modern demography, the 17th-century English writers and mathematicians William Petty and John Graunt, were “thinking through problems of population and mobility at precisely the moment when England had solidified its commitment to the slave trade.”Their questions were ones of statecraft: How could England increase its wealth? How could it handle its surplus population? And what would it do with “excessive populations that did not consume” in the formal market? Petty was concerned with Ireland — Britain’s first colony, of sorts — and the Irish. He thought that if they could be forcibly transferred to England, then they could, in Morgan’s words, become “something valuable because of their ability to augment the population and labor power of the English.”This conceptual breakthrough, Morgan told me in an interview, cannot be disentangled from the slave trade. The English, she said, “are learning to think about people as ‘abstractable.’
This deserves to be delved into more deeply. This sounds like a bizarre stop on the creation of institutional racism.
How do these sorts of abstraction hurt the move towards equality?

The WebSocket Protocol is designed on the principle that there should be minimal framing (the only framing that exists is to make the protocol frame-based instead of stream-based and to support a distinction between Unicode text and binary frames). It is expected that metadata would be layered on top of WebSocket by the application Fette & Melnikov Standards Track [Page 9] RFC 6455 The WebSocket Protocol December 2011 layer, in the same way that metadata is layered on top of TCP by the application layer (e.g., HTTP). Conceptually, WebSocket is really just a layer on top of TCP that does the following: o adds a web origin-based security model for browsers o adds an addressing and protocol naming mechanism to support multiple services on one port and multiple host names on one IP address o layers a framing mechanism on top of TCP to get back to the IP packet mechanism that TCP is built on, but without length limits o includes an additional closing handshake in-band that is designed to work in the presence of proxies and other intermediaries Other than that, WebSocket adds nothing. Basically it is intended to be as close to just exposing raw TCP to script as possible given the constraints of the Web. It's also designed in such a way that its servers can share a port with HTTP servers, by having its handshake be a valid HTTP Upgrade request. One could conceptually use other protocols to establish client-server messaging, but the intent of WebSockets is to provide a relatively simple protocol that can coexist with HTTP and deployed HTTP infrastructure (such as proxies) and that is as close to TCP as is safe for use with such infrastructure given security considerations, with targeted additions to simplify usage and keep simple things simple (such as the addition of message semantics).

The adapter is where authentication, policy checks, and eventually your domain logic happen. All termini of the protocol’s activity are standardized end events - that’s how protocol and adapter communicate.
-
An endpoint links your routing with your business code. The idea is that your controllers are pure HTTP routers, calling the respective endpoint for each action. From there, the endpoint takes over, handles authentication, policies, executing the domain code, interpreting the result, and providing hooks to render a response.

Trailblazer extends the conventional MVC stack in Rails. Keep in mind that adding layers doesn't necessarily mean adding more code and complexity. The opposite is the case: Controller, view and model become lean endpoints for HTTP, rendering and persistence. Redundant code gets eliminated by putting very little application code into the right layer.

Declarative programming is an enabler of abstraction. Imperative programming is an inhibitor of abstraction. Declarative programming allows you to say “I want this and I don’t care how I get it” while imperative programming requires you to define each and every step.
Declarative programming, i.e. "build me a house, I don't care how", is an enabler of abstraction.
Imperative programming, i.e. "build walls, windows, a roof.", is an inhibitor of abstraction.

Now of course we know how React handles this conflict: it takes the new nodes in your virtual DOM tree — the waters in your flowing river — and maps them onto existing nodes in the DOM. In other words React is a functional abstraction over a decidedly non-functional substrate.
To me this is a warning sign, because in my experience, the bigger the gap between an abstraction and the thing it abstracts, the more likely you are to suffer what programmers like to call ‘impedance mismatches’, and I think we do experience that in React.
