    1. The Essential Habits ofDigital Organizers

      This chapter is too entailed with productivity advice, which can be useful to some, but isn't as note taking focused for those who probably need more of that.

      What is the differentiator between knowledge workers, knowledge creators, students, researchers, academics. How do we even clearly delineate knowledge worker as a concept. It feels far too nebulous which makes it more difficult to differentiate systems for them to use for improving productivity and efficiency.

    2. If we overlay the four steps of CODE onto the model ofdivergence and convergence, we arrive at a powerful template forthe creative process in our time.

      The way that Tiago Forte overlaps the idea of C.O.D.E. (capture/collect, organize, distill, express) with the divergence/convergence model points out some primary differences of his system and that of some of the more refined methods of maintaining a zettelkasten.

      A flattened diamond shape which grows from a point on the left so as to indicate divergence from a point to the diamond's wide middle which then decreases to the right to indicate convergence  to the opposite point. Overlapping this on the right of the diamond are the words "capture" and "organize" while the converging right side is overlaid with "distill" and "express". <small>Overlapping ideas of C.O.D.E. and divergence/convergence from Tiago Forte's book Building a Second Brain (Atria Books, 2022) </small>

      Forte's focus on organizing is dedicated solely on to putting things into folders, which is a light touch way of indexing them. However it only indexes them on one axis—that of the folder into which they're being placed. This precludes them from being indexed on a variety of other axes from the start to other places where they might also be used in the future. His method requires more additional work and effort to revisit and re-arrange (move them into other folders) or index them later.

      Most historical commonplacing and zettelkasten techniques place a heavier emphasis on indexing pieces as they're collected.

      Commonplacing creates more work on the user between organizing and distilling because they're more dependent on their memory of the user or depending on the regular re-reading and revisiting of pieces one may have a memory of existence. Most commonplacing methods (particularly the older historic forms of collecting and excerpting sententiae) also doesn't focus or rely on one writing out their own ideas in larger form as one goes along, so generally here there is a larger amount of work at the expression stage.

      Zettelkasten techniques as imagined by Luhmann and Ahrens smooth the process between organization and distillation by creating tacit links between ideas. This additional piece of the process makes distillation far easier because the linking work has been done along the way, so one only need edit out ideas that don't add to the overall argument or piece. All that remains is light editing.

      Ahrens' instantiation of the method also focuses on writing out and summarizing other's ideas in one's own words for later convenient reuse. This idea is also seen in Bruce Ballenger's The Curious Researcher as a means of both sensemaking and reuse, though none of the organizational indexing or idea linking seem to be found there.

      This also fits into the diamond shape that Forte provides as the height along the vertical can stand in as a proxy for the equivalent amount of work that is required during the overall process.

      This shape could be reframed for a refined zettelkasten method as an indication of work

      Forte's diamond shape provided gives a visual representation of the overall process of the divergence and convergence.

      But what if we change that shape to indicate the amount of work that is required along the steps of the process?!

      Here, we might expect the diamond to relatively accurately reflect the amounts of work along the path.

      If this is the case, then what might the relative workload look like for a refined zettelkasten? First we'll need to move the express portion between capture and organize where it more naturally sits, at least in Ahren's instantiation of the method. While this does take a discrete small amount of work and time for the note taker, it pays off in the long run as one intends from the start to reuse this work. It also pays further dividends as it dramatically increases one's understanding of the material that is being collected, particularly when conjoined to the organization portion which actively links this knowledge into one's broader world view based on their notes. For the moment, we'll neglect the benefits of comparison of conjoined ideas which may reveal flaws in our thinking and reasoning or the benefits of new questions and ideas which may arise from this juxtaposition.

      Graphs of commonplace book method (collect, organize, distill, express) versus zettelkasten method (collect, express, organize (index/link), and distill (edit)) with work on the vertical axis and time/methods on the horizontal axis. While there is similar work in collection the graph for the zettelkasten is overall lower and flatter and eventually tails off, the commonplace slowly increases over time.

      This sketch could be refined a bit, but overall it shows that frontloading the work has the effect of dramatically increasing the efficiency and productivity for a particular piece of work.

      Note that when compounded over a lifetime's work, this diagram also neglects the productivity increase over being able to revisit old work and re-using it for multiple different types of work or projects where there is potential overlap, not to mention the combinatorial possibilities.


      It could be useful to better and more carefully plot out the amounts of time, work/effort for these methods (based on practical experience) and then regraph the resulting power inputs against each other to come up with a better picture of the efficiency gains.

      Is some of the reason that people are against zettelkasten methods that they don't see the immediate gains in return for the upfront work, and thus abandon the process? Is this a form of misinterpreted-effort hypothesis at work? It can also be compounded at not being able to see the compounding effects of the upfront work.

      What does research indicate about how people are able to predict compounding effects over time in areas like money/finance? What might this indicate here? Humans definitely have issues seeing and reacting to probabilities in this same manner, so one might expect the same intellectual blindness based on system 1 vs. system 2.

      Given that indexing things, especially digitally, requires so little work and effort upfront, it should be done at the time of collection.

      I'll admit that it only took a moment to read this highlighted sentence and look at the related diagram, but the amount of material I was able to draw out of it by reframing it, thinking about it, having my own thoughts and ideas against it, and then innovating based upon it was incredibly fruitful in terms of better differentiating amongst a variety of note taking and sense making frameworks.

      For me, this is a great example of what reading with a pen in hand, rephrasing, extending, and linking to other ideas can accomplish.

    1. Curiosity is a productivity app that gives you one place to search all your files and apps. That lets you save time and get more done.Curiosity connects with the tools you already use, including your local folders and cloud apps like Google Drive or Slack. You can use the shortcut-powered command bar to access things quickly and the file browser for deeper searches with advanced filters.
    1. Energy efficiency has never been more crucial! The time to unleashing its massive potential has come

      Will this conference debate rebound effects of efficiency? If not, it will not have the desirable net effect.

      My linked In comments were:

      Alessandro Blasi, will this conference address the rebound effect? In particular, Brockway et al. have done a 2021 meta-analysis of 33 research papers on rebound effects of energy efficiency efforts and conclude:

      "...economy-wide rebound effects may erode more than half of the expected energy savings from improved energy efficiency. We also find that many of the mechanisms driving rebound effects are overlooked by integrated assessment and global energy models. We therefore conclude that global energy scenarios may underestimate the future rate of growth of global energy demand."


      Unless psychological and sociological interventions are applied along with energy efficiency to mitigate rebound effects, you will likely and ironically lose huge efficiencies in the entire efficiency intervention itself.

      Also, as brought up by other commentators, there is a difference between efficiency and degrowth. Intelligent degrowth may work, especially applied to carbon intensive areas of the economy and can be offset by high growth in low carbon areas of the economy.

      Vaclav Smil is pessimistic about a green energy revolution replacing fossil fuels https://www.ft.com/content/71072c77-53b3-4efd-92ae-c92dc02f09ad, which opens up the door to serious consideration of degrowth, not just efficiency improvements. Perhaps the answer is in a combination of all of the above, including targeted degrowth.

      Technology moves quickly and unexpectedly. At the time of Smil's book release, there was no low carbon cement. Now there is a promising breakthrough: https://www.cnbc.com/2022/04/28/carbon-free-cement-breakthrough-dcvc-put-55-million-into-brimstone.html

      As researchers around the globe work feverishly to make low carbon breakthroughs, there is obviously no guarantee of when they will occur. In that case then, with only a few years to peak, it would seem the lowest risk pathway would be to prioritize the precautionary principle over a gambling pathway (such as relying on Negative Emissions Technology breakthroughs) and perhaps consider along with rebound effect conditioned efficiency improvements also include a strategy of at least trialing a temporary, intentional degrowth of high carbon industries / growth of low carbon industries.

    1. Research has shown that,across disciplines, experts look in ways different from novices: they take in thebig picture more rapidly and completely, while focusing on the most importantaspects of the scene; they’re less distracted by visual “noise,” and they shiftmore easily among visual fields, avoiding getting stuck.

      Experts have more practiced levels of visual perception of surroundings that provide them with information more quickly than novices who don't yet know what or where to focus their attention. Teaching with eye tracking technology might help to bridge the gap between novice and expert more quickly.

    1. That’s all fine and well and good as long as you don’t have a crisis

      Systems that are too efficient will become brittle. Brittle systems collapse catastrophically when conditions vary too far from expectations. The only way to accommodate unforeseeable circumstances is to give up some efficiency for greater flexibility. This produces robust systems that endure where brittle systems collapse.

    1. A coach is not there to do the work,but to show us how to use our time and effort in the most effectiveway.

      Much as coaches help their athletes become better, teachers are there to help students use their time and work efforts in the most effective ways.

    2. Only after aligning every single part of the delivery chain, frompackaging to delivery, from the design of the ships to the design ofthe harbours, was the full potential of the container unleashed.

      Streamlining one's entire workflow from start to finish can unleash tremendous amounts of additional system-wide productivity. Starting out by tinkering with small things here and there is more likely to doom these smaller individual changes to failure with out associated global changes.

      Once the overall system has been redesigned and reconfigured, then one can make and perfect smaller scale local changes.

      Link this to the idea of kelp and sailing/rowing from The West Wing.

    3. We need a reliable and simple external structure tothink in that compensates for the limitations of our brains

      Let's be honest that there are certainly methods for doing all of this within our brains and not needing to rely on external structures. This being said, using writing, literacy, and external structures does allow us to process things faster than before.

      Can we calculate what the level of greater efficiency allows for doing this? What is the overall throughput difference in being able to forget and write? Not rely on communication with others? What does a back of the envelope calculation for this look like?

    1. Yes, precisely because I've been involved in maintaining codebases built without real full stack frameworks is why I say what I said.The problem we have in this industry, is that somebody reads these blog posts, and the next day at work they ditch the "legacy rails" and starts rewriting the monolith in sveltekit/nextjs/whatever because that's what he/she has been told is the modern way to do full stack.No need to say those engineers will quit 1 year later after they realize the mess they've created with their lightweight and simple modern framework.I've seen this too many times already.It is not about gatekeeping. It is about engineers being humble and assume it is very likely that their code is very unlikely to be better tested, documented, cohesive and maintained than what you're given in the real full stack frameworks.Of course you can build anything even in assembler if you want. The question is if that's the most useful thing to do with your company's money.

    1. All four of these extraneural resources — technology, the body, physical space, social interaction — can be understood as mental extensions that allow the brain to accomplish far more than it could on its own.

      Technology, the body, physical space, and social interaction can be extensions of the mind.

      What others might exist? Examples?

    1. To me, the greatest benefit of IndexCards is that they force you to not write too much. This is a big help to those of us who are still squishing the bitter juice of BigDesignUpFront from our brains. The expense and rarity of vellum played a similar role in MedievalArchitecture.
    2. This is one of the points made in TheMythOfThePaperlessOffice -- that workplaces often shift from more efficient paper-based technologies to less efficient electronic technologies (electronic technologies can be either more or less efficient, of course) because computers symbolize The Future, Progress, and a New Way Of Doing Things. An office on the move, that's what an office that uses cutting-edge technology is. Not an office that is stuck in the past. And the employees are left to cope with the less productive, but shinier, New Way. -- ApoorvaMuralidhara

      New technologies don't always have the user interface to make them better than old methods.

    1. Joe learned the most efficient way to use his body by acquiring a set of routines that were quick and preserved energy. Otherwise he would never have survived on the line.

      Sometime in the past six months I ran across a description of how migrant workers do this sort of activity in farming contexts. That article also pointed out the fact that the average person couldn't do this sort of work and that there was extreme value in it.

    1. Sure, the slow way is always "good enough" — until you learn a better way of doing things. By your logic, then, we shouldn't have the option of including "Move to" in our context menus either — because any move operation could be performed using the cut and paste operations instead? The method you proposed is 6-7 steps long, with step 4 being the most onerous when you're in a hurry: Select files "Cut" "Create New Folder" Think of a name for the new folder. Manually type in that name, without any help from the tool. (We can't even use copy and paste to copy some part of one of the file names, for example, because the clipboard buffer is already being used for the file selection.) Press Enter Press Enter again to enter the new folder (or use "Paste Into Folder") "Paste" The method that Nautilus (and apparently Mac's Finder) provides (which I and others love) is much more efficient, especially because it makes step 4 above optional by providing a default name based on the selection, coming in at 4-5 steps (would be 3 steps if we could assign a keyboard shortcut to this command like Mac apparently has ): Select files Bring up context menu (a direct shortcut key would make this even sweeter) Choose "New Folder With Selection" Either accept the default name or choose a different name (optional) Press Enter Assuming "Sort folders before files" option is unchecked, you can continue working/sorting in this outer folder, right where you left off: Can you see how this method might be preferable when you have a folder with 100s or 1000s of files you want to organize it into subfolders? Especially when there is already a common filename prefix (such as a date) that you can use to group related files together. And since Nemo kindly allows us to choose which commands to include in our context menu, those who don't use/like this workflow are free to exclude it from their menus... Having more than one way to accomplish something isn't necessarily a bad thing.

    1. “In the past the man has been first,” he declared; “in the future the system must be first.”

      This is the problem however. We can't program humans out of the equation entirely, for what is the general enterprise meant for in the first place?

    2. The goal, as Taylor defined it in his celebrated 1911 treatise, The Principles of Scientific Management, was to identify and adopt, for every job, the “one best method” of work and thereby to effect “the gradual substitution of science for rule of thumb throughout the mechanic arts.”

    1. Tech support works with scripts. Just get to know these scripts by heart and answer all questions from the script you can in one long sentence, before they ask it. Like in "Hi I have a problem with this and that...I have restarted the router, I have checked the cables, the red light is on, the green light is off, not other lights are blinking......etc.etc.etc. That way the person at the other end of the line can just go click-click-click and you'll be 10 steps further in their script in 5 seconds.
    1. I want to avoid nginx overhead (especially if they have tons of alias and rewrites) for in-server communication. Basically, you can have sveltekit server, backend server and nginx server, in that case, communicate inside your internal network will be very expensive like: browser->nginx server(>sveltekit server(>nginx server(>backend server( instead just: browser->nginx server(>sveltekit server(>backend server(
    1. two distinct paths to success have emerged, and students should decide early in their graduate school careers which path to travel. Is their primary objective to obtain a degree as expediently as possible, or is it to learn? These two goals are not always mutually exclusive, and with genuine curiosity and perseverance, independent learning is possible. However, the path for obtaining a degree ­efficiently is not obvious, and the guidelines in this regard can be elusive, unspoken and often unrealised.

    1. If you're using webpack with svelte-loader, make sure that you add "svelte" to resolve.mainFields in your webpack config. This ensures that webpack imports the uncompiled component (src/index.html) rather than the compiled version (index.mjs) — this is more efficient.
    1. Frankly, if the Ubuntu Desktop team “switch” from making a deb of Chromium to making a snap, I doubt they’d switch back. It’s a tremendous amount of work for developer(s) to maintain numerous debs across all supported releases. Maintaining a single snap is just practically and financially more sensible.
    2. This example of the chromium really shows that unless snaps or other similar format was used, applications would have to be sometime very heavily patched to work on older versions of systems to the point that it generates so much work that it would not be worth do to it otherwise, or at least not worth when the snap option exists and doesn’t require that much more work.

    1. Better contribution workflow: We will be using GitHub’s contribution tools and features, essentially moving MDN from a Wiki model to a pull request (PR) model. This is so much better for contribution, allowing for intelligent linting, mass edits, and inclusion of MDN docs in whatever workflows you want to add it to (you can edit MDN source files directly in your favorite code editor).

    1. Please don't copy answers to multiple questions; this is the same as your answer to a similar question

      Why on earth not? There's nothing wrong with reusing the same answer if it can work for multiple questions. That's called being efficient. It would be stupid to write a new answer from scratch when you already have one that can work very well and fits the question very well.

    1. Node doesn't have a DOM available. So in order to render HTML we use string concatenation instead. This has the fun benefit of being quite efficient, which in turn means it's great for server rendering!
    1. But is overhead always bad? I believe no — otherwise Svelte maintainers would have to write their compiler in Rust or C, because garbage collector is a single biggest overhead of JavaScript.

    1. In a previous post, we discussed “combining and conquering” the GDPR. That is, how the work done to meet various GDPR requirements can be leveraged when addressing others. This same concept applies here — synchronize your consent records with other areas such as your records of processing or data subject requests to assist with compliance. Doing so, for example, will enable you to quickly trace a withdrawal back to a particular processing activity or data subject request that needs to be reviewed.

    1. A left navigation is faster and more efficient for users to scan. In just three visual fixations, users scan six items in the left navigation compared to the three items scanned in the top navigation. The left navigation also facilitates a vertical scanning direction that is natural for people

    1. Not every problem should lead to a new process to prevent them. Additional processes make all actions more inefficient, a mistake only affects one.
    2. Use the simplest and most boring solution for a problem, and remember that “boring” should not be conflated with “bad” or “technical debt.” The speed of innovation for our organization and product is constrained by the total complexity we have added so far, so every little reduction in complexity helps. Don’t pick an interesting technology just to make your work more fun; using established, popular tech will ensure a more stable and more familiar experience for you and other contributors.
    1. Automation helps us keep these steps out of our way while maintaining control through fast feedback loops (context-switching is our enemy).
    1. Never compile the same project twice Nix allows to easily share build results across machines. If the CI has built the project, developers or servers can download the build results instead of re-building the same thing.

    1. Because moving tasks around is as easy as dragging a row to a new location, you can easily re-prioritize without jumping between views or clicking twelve times to get where you need to go.

      I do love the drag-and-drop ability of rows/columns in Sheets!

    2. And it requires way fewer clicks than most other options. And let's face it: Nobody has time for extra clicks—you just want to get work done, not manage the work you need to get done.

    1. Eliminating the fraction of demand that occurs in these spikes eliminates the cost of adding reserve generators, cuts wear and tear and extends the life of equipment, and allows users to cut their energy bills by telling low priority devices to use energy only when it is cheapest.

    1. You were beginning to gather that there were other symbols mixed with the words that might be part of a sentence, and that the different parts of what made a full-thought statement (your feeling about what a sentence is) were not just laid out end to end as you expected.

      This suggests that Joe is doing something almost completely unrecognizable--with language at least. I guess my assumption is that I would know what Joe was doing he'd just be doing it so quickly I wouldn't be able to follow. And he'd complete the task--a task I recognize--far more quickly than I possibly could using comparable analog technologies. Perhaps this is me saying, I buy Englebart's augmentation idea on the level of efficiency but remain skeptical or at least have yet to realize it's transformative effect on intellect itself.

    1. prolonged interaction between the instructor and the students

      I'm always a little proud when I say that Hypothesis will not make things easier/more efficient for teachers. If anything, it helps widen and deepen this "prolonged interaction between the instructor and students," which takes even more time!

    1. “Faced with declining tax revenues, counties and municipalities are turning over the operation of parts of the criminal justice system to private corporations that promise to provide legally mandated services at “no cost to taxpayers”. These companies then charge fees for these same services to individuals accused of crimes or on probation – fees higher than what states would charge for equivalent services, if they charge at all. Often already impoverished, those many who can’t pay the fees are now being imprisoned for debt.” “Contracting-out is a vast and growing part of the federal government. Contract spending mushroomed from $200 billion in 2000 to $530 billion in 2011. The total cost of federal contract employees is twice that of federal civil servants… The POGO study – Bad Business 55 … found that “billions of dollars [are] wasted on hiring contractors” based on “a misguided assumption that market economies enable contractors to be more cost efficient than the government. On average, contractors charged the federal government more than twice the amount it pays federal workers.”

      Wouldn't that ease of gathering only be viable for a certain amount of time, in certain areas? With larger populations and in scarcer areas, that time increases. I wonder what other statistics or sources provide similar or disparate numbers, and how those numbers change over time. When did gathering become less efficient?

    1. “My feeling at the time was this was a good idea,” Dr. Wachter says. “The trend toward our system being pushed to deliver better, more efficient care was going to be enduring, and the old model of the primary-care doc being your hospital doc … couldn’t possibly achieve the goal of producing the highest value.”

      How can care be made further efficient? E.g., integration, cost-sharing, payment-sharing, parent partners, nurse partners

    1. efficiency has come to mean accomplishing a task with the least possible human intervention—a goal that often turns out to be self-defeating, particularly when efficiency becomes almost an end in itself. Recall Thomas Edison’s famous line that genius is one percent inspiration and 99 percent perspiration and contrast it with our contemporary enthusiasm for machine-like efficiency

      Interesting connection here between the efficiency mandate and the "talent means no effort required" attitude we see in many school settings.

    1. We are on the threshold of sweeping change that will make it easier for teachers to teach and students to learn faster and more effectively

      I see this as evidence of technology determinism, which this article is shot through with. This kind of sentiment comes off as if technologies make things better, faster, more efficient for all involved parties, without consequence. It also assumes a consensus around what improved teaching and learning looks like and means. IMO, "efficiency" recalls turn of 20th century industrialist philosophy and rhetoric. In the work of education, I think that we need to ask if efficiency really is always better, and better for who. I am suggesting that in many cases efficiency is better for administrators from a business perspective, but not so for learners.

    1. I only skimmed this, but I think I got the point. You move more people faster on escalators when none of them are reserved for walking -- simply because not enough people are willing or able to walk. If you have walking lanes, they are under-used, and the standing lanes are over-crowded.
