“[It's] an amazing tool for brainstorming or rubber-ducking. Its conversational quality is perfect to talk about plot, characters and worldbuilding.”- Nelly Garcia
Presumably the use of rubber-ducking here is an indicator of Nelly Garcia's background with programming and prior AI tool use?

Among other things, I have traditionally used my Journal to think out loud to myself about my work in hand: the progress I’m making, the problems I’m encountering, and so on. Many of my best ideas have arisen by writing to myself like this.
Richard Carter uses his writing journal practice to "think out loud" to himself. Often, laying out extended arguments helps people to refine and reshape their thinking as they're better able to see potential holes or missing pieces of arguments. It's the same sort of mechanism which is at work in rubber duck debugging of computer code: by explaining a process one is more easily able to see the missing pieces, errors, or problems with the process at hand.
Carter's separate note taking and writing journal practice being used as a thought space or writing workshop of sorts is very similar to the process seen in my preliminary studies of Henry David Thoreau's work in which he kept commonplace books and separate (writing) journals which show evidence of his trying ideas on for size and working them before committing them to his published works.

Nobody ever says rubber ducky debugging involves writing memos to your preferred duck, after all.
Seemingly both rubber duck debugging and casual conversations with acquaintances would seem to be soft forms of diffuse thinking which may help one come to a heuristic-based decision or realization.
These may be useful, but should also be used in combination with more logical, system two forms of decision making. (At least not in the quick, notice the problem sort of issues in which one may be debugging.)

Moreover, because the entire language and development system are available, unrestricted, in the repl, you can define the missing function bar, resume foo, and get a sensible result.
This seems like one of the key points. The ability to edit computations while running. Type holes with resuming gets you most of the way there but there's probably also modifications. I wonder how you can keep it from getting confusing. Something similar to FRP?

Debugging is the process of finding and removing errors (bugs) from a software program. Bugs occur in programs when a line of code or a statement conflicts with other elements of the code. We also call errors or defects in hardware bugs.

a constellation already described in 1805 by Heinrich von Kleist in his fascinat-ing analysis of the “Midwifery of Thought”: “If you want to know something and cannotfind it through meditation, I advise you, my dear, clever friend, to speak about it withthe next acquaintance who bumps into you.” 43 The positive tension that such a conversa-tion immediately elicits through the expectations of the Other obliges one to producenew thought in the conversation. The idea develops during speech. There, the sheeravailability of such a counterpart, who must do nothing further (i.e., offer additionalstimulus through keen contradiction of the speaker) is already enough; “There is a specialsource of excitement, for him who speaks, in the human face across from him; and agaze which already announces a half-expressed thought to be understood often givesexpression to the entire other half.”44
- Heinrich von Kleist, “Ü ber die allm ä hliche Verfertigung der Gedanken beim Reden,” in Sämtliche Werke und Briefe. Zweiter Band, ed. Helmut Sembdner (M ü nchen: dtv, 1805/2001), 319 – 324, at 319.
- Ibid., 320.
in 1805 Heinrich von Kleist noted that one can use conversation with another person, even when that person is silent, to come up with solutions or ideas they may not have done on their own.
This phenomena is borne out in modern practices like the so-called "rubber duck debugging", where a programmer can talk to any imagined listener, often framed as a rubber duck sitting on their desk, and talk through the problem in their code. Invariably, talking through all the steps of the problem will often result in the person realizing what the problem is and allow them to fix it.
This method of verbal "conversation" obviously was a tool which indigenous oral cultures frequently used despite the fact that they didn't have literacy as a tool to fall back on.

I feel like better code visualization would solve a lot of my problems. Or at least highlight them.
The other commenter talks about a typical sw.eng. approach to visualization (flame graphs), but I want programs visualized as a manufacturing/packing/assembly line on a factory floor. Almost like node editors like Unreal's Blueprints, but in three dimensions, and shit visibly moving around between tools on the line in a way that you can actually perceive. Run the testcase on a loop, so you have a constant stream of "shit visibly moving around", and it runs at fractional speed so the whole process takes, say 10 seconds from front-to-back instead of near instantaneously like it normally would (and allow the person who's debugging to control the time scaling, of course). You find bugs by walking the line and seeing, "oh, man, this purple shit is supposed to be a flanged green gewgaw at this point in the line", so you walk over and fix it.
(This is what I want VR to really be used for, instead of what's capturing people's attention today—games and lame substitutes for real world interaction like Zuckerberg is advocating for.)

Another effective technique is to start your notetaking by writing a short summary of each chapter and transcribing any meaningful passages or phrases. If you are unsure how to simplify your thoughts, imagine that someone has tapped you on the shoulder and asked you to explain the chapter you just finished reading. They have never read this book and lack any idea of the subject matter. How would you explain it to them?
The so-called Richard Feynman technique, n'cest pas?
From whom did he crib it? Did he credit them, or was it just distilled into part of the culture?
This is also similar to the rubber duck method of debugging a program in some sense.

In his “On the gradual fabrication of thoughts while speaking,” Kleist was in turn musing on Immanuel Kant’s metaphor of the teacher as the midwife at the birth of the student’s thought. When stuck in developing a thought, Kleist recommends, find an acquaintance to talk at. No responses are required. The mere presence of the silent interlocutor, and even more so the imminent threat of losing their attention during lengthy stretches of boredom or incoherence will trigger, or so Kleist claims, the “fabrication of my idea in reason’s workshop.”
This sounds a lot like a broader case than rubber duck debugging, which is obviously not a "new" thing.

I used this in the console to find the file and the line of the error (took it from this answer): JS_PATH = "app/assets/javascripts/**/*.js"; Dir[JS_PATH].each do |file_name| puts "\n#{file_name}" puts Uglifier.compile(File.read(file_name)) end
Didn't work for me because it was actually a .coffee file.
So I tried something similar with this:
main > Dir["*/assets/javascripts/**/*.coffee"].each { |file_name| puts "\n#{file_name}"; Sprockets::CoffeeScriptProcessor.(filename: file_name, data: File.read(file_name), cache: {}); } app/assets/javascripts/bootstrapped.js.coffee NoMethodError: undefined method `config' for nil:NilClass from /home/tyler/.gem/ruby/2.7.1/gems/sprockets-4.0.2/lib/sprockets/source_map_utils.rb:40:in `format_source_map'but it wasn't as trivial to provide the necessary environment that Sprockets wants.
But that's okay, when better_errors paused on the exception, I just jumped to the
block in Sprockets::CoffeeScriptProcessor.call sprockets (4.0.2) lib/sprockets/coffee_script_processor.rb, line 24frame and evaluated
input[:filename]to figure out which file had failed.
Obviously this information should be part of the error message itself though!!

You’re allowed to blame us for a terrible developer experience in Trailblazer 2.0. It’s been quite painful to find out which step caused an exception. However, don’t look back in anger! We’ve spent a lot of time on working out a beautiful way for both tracing and debugging Trailblazer activities in 2.1.

To tell you the truth, the new tracing feature was the original reason why I decided to write 2.1 and make you sit and wait in agony for years. Nevertheless, tracing is simply blowing my mind. I can’t count how many hours and angering rushs of adrenaline I’ve saved since the introduction of the wtf? method and its helpful higher-level stack trace.

LogRocket is a frontend application monitoring solution that lets you replay problems as if they happened in your own browser. Instead of guessing why errors happen, or asking users for screenshots and log dumps, LogRocket lets you replay the session to quickly understand what went wrong. It works perfectly with any app, regardless of framework, and has plugins to log additional context from Redux, Vuex, and @ngrx/store. In addition to logging Redux actions and state, LogRocket records console logs, JavaScript errors, stacktraces, network requests/responses with headers + bodies, browser metadata, and custom logs. It also instruments the DOM to record the HTML and CSS on the page, recreating pixel-perfect videos of even the most complex single-page apps.

I’ll give you a more concrete example. I was writing a technical post yesterday. During the writing process, I found a way to make my code more efficient. When I write, I tend to analyze more than I do at any other time. I analyzed my code with a more critical eye because I wanted to offer you, the reader, the best experience. This is an experience I have had many times throughout writing on this blog.
This also sounds very closely related to the idea of rubber duck debugging.

in Python - setting up basic logger is very simple
Apart from printing the result, it is better to debug with logging.
Sample logger:
import logging logging.basicConfig( filename='application.log', level=logging.WARNING, format= '[%(asctime)s] {%(pathname)s:%(lineno)d} %(levelname)s - %(message)s', datefmt='%H:%M:%S' ) logging.error("Some serious error occurred.") logging.warning('Function you are using is deprecated.')the sample result:
[12:52:35] {<stdin>:1} ERROR - Some serious error occurred. [12:52:35] {<stdin>:1} WARNING - Function you are using is deprecated.to find its location, type:
logging.getLoggerClass().root.handlers[0].baseFilename

Tip: Use Logpoints instead of print statements: Developers often litter source code with print statements to quickly inspect variables without necessarily stepping through each line of code in a debugger. In VS Code, you can instead use Logpoints. A Logpoint is like a breakpoint except that it logs a message to the console and doesn't stop the program. For more information, see Logpoints in the main VS Code debugging article.
Try to use logpoints instead of print statements.

One quick trick for making it easier for debugging/understanding your threading macros is to put print statements in between some of the steps. The important thing to remember is that all the print functions in clojure return nil so you need to make a little helper function (I like to call mine ?) that prints and then returns the original input, like this: (defn ? [x] (prn x) x)

Default Value
Please note that the values listed below are the default ones. An Option can represent a Boolean toggle flag (i.e.
HeapDumpOnOutOfMemoryError,PrintConcurrentLocks). For such Options, '+' and '-' flags deal with Boolean toggling. In short:- '+' means Enable (or set to '1');
- '-' means Disable (or set to '0').
For example, in the table pertaining to Debugging Options, by default the
-XX:-HeapDumpOnOutOfMemoryErroris Disabled, because it has the-prepended to it. To actually Enable it, change that with+, yielding the variant-XX:+HeapDumpOnOutOfMemoryError.
