    1. Engaging in a Zettelkasten/Commonplace book in this way is equal to inherent spaced repetition and recall perhaps?

      Especially if you allow some time of rumination... Read book, wait a few days to a few weeks before processing it. The book's contents remain in the back of your mind.

      Then when processing you get engaged with the substance again and therefore interrupt the ebbinghaus curve.

    1. "But there's a very famous theorem in topology called the Jordan curve theorem. You have a plane and on it a simple curve that doesn't intersect and closes—in other words, a loop. There's an inside and an outside to the loop." As Riehl draws this, it seems obvious enough, but here's the problem: No matter how much your intuition tells you that there must be an inside and an outside, it's very hard to prove mathematically that this holds true for any loop that can be drawn.

      How does one concretely define "inside" and "outside"? This definition is part of the missing space between the intuition and the mathematical proof.

    1. From the Introduction to Ed25519, there are some speed benefits, and some security benefits. One of the more interesting security benefits is that it is immune to several side channel attacks: No secret array indices. The software never reads or writes data from secret addresses in RAM; the pattern of addresses is completely predictable. The software is therefore immune to cache-timing attacks, hyperthreading attacks, and other side-channel attacks that rely on leakage of addresses through the CPU cache. No secret branch conditions. The software never performs conditional branches based on secret data; the pattern of jumps is completely predictable. The software is therefore immune to side-channel attacks that rely on leakage of information through the branch-prediction unit. For comparison, there have been several real-world cache-timing attacks demonstrated on various algorithms. http://en.wikipedia.org/wiki/Timing_attack

      Further arguments that Ed25519 is less vulnerable to - cache-timing attacks - hyperthreading attacks - other side-channel attacks that rely on leakage of addresses through CPU cache Also boasts - no secret branch conditions (no conditional branches based on secret data since pattern of jumps is predictable)

      Predicable because underlying process that generated it isn't a black box?

      Could ML (esp. NN, and CNN) be a parallel? Powerful in applications but huge risk given uncertainty of underlying mechanism?

      Need to read papers on this

    2. More "sales pitch" comes from this IETF draft: While the NIST curves are advertised as being chosen verifiably at random, there is no explanation for the seeds used to generate them. In contrast, the process used to pick these curves is fully documented and rigid enough so that independent verification has been done. This is widely seen as a security advantage, since it prevents the generating party from maliciously manipulating the parameters. – ATo Aug 21, 2016 at 7:25

      An argument why Ed25519 signature alg & Curve 25519 key exchange alg is more secure; less vulnerable to side attacks since the process that generates is have been purportedly verified and extensively documented.

    1. An important aspect missing in typical flow models is that in order to produce enduringcommitment a goal should correspond to something truly valuable. For example, while the goal ofshooting a maximum number of spaceships in your game of Space Invaders may be clear, it doesnot satisfy any real needs. Therefore, playing games, however enjoyable at the time, if continuedlong enough will eventually leave you with the feeling of having wasted your time. One way gamedesigners try to overcome this limitation is by creating a sense of “epic meaning” (McGonigal,2011), i.e. situating the game action in a narrative context which implies that something truly greator valuable is being achieved (like saving the world from alien invaders).

      The epic meaning of "Bend the Curve" is saving civilization, co-creating a future worth living in the next few years, averting disaster.

      On a personal level the transformation of the individual also conveys epic meaning.

    1. The richest 10 percent accounted for over half (52 percent) of the emissions added to the atmosphere between 1990 and 2015. The richest one percent were responsible for 15 percent of emissions during this time – more than all the citizens of the EU and more than twice that of the poorest half of humanity (7 percent).

      This is a key leverage point strategy for Stop Reset Go for Rapid Whole System Change (RWSC) strategy. As argued by Kevin Anderson https://youtu.be/mBtehlDpLlU, the wealthy are a crucial subculture to target and success can lead to big decarbonization payoffs.

      The key is to leverage what contemplative practitioners and happiness studies both reveal - after reaching a specific level of material needs being met, which is achievable for staying within planetary boundaries, we don’t need any more material consumption to be happy. We need an anti-money song: https://youtu.be/_awAH-JJx1kamd and enliven Martin Luther King Junior’s quote aspirational: the only time to look down at another person is to give them a hand up. Educate the elites on the critical role they now play to solve the double problem of i equality and runaway carbon emissions.

    1. In contrast to the unhelpful but common argument about whether ‘the problem’ is population growth or consumption, it is not novel to argue that the problem is both—plus waste. Because of ongoing need for progress on all three, this point of intervention is nonetheless key. Unlike research on impact as a function of population, affluence and technology (1 = PAT), we point to strong opportunities to decouple affluence from material consumption [leverage point 1]. We also side with those who argue that more efficient production is insufficient, and that volumes of production and consumption are key variables

      All three variables - population growth, consumption and waste must be minimized simultaneously in order to bend the curve back to a safe operating safe for humanity

    1. The HRF design intends to operationalize entangled security (figure 8). It provides orchestration logic at ecoregional, nation-state, and local levels and is expected to vary  according to context. It comprises four main task groups: HRF support; planetary security; human security; and state security.

      These are umbrella categories that can allow for the classification of vast numbers of existing transition projects. With the use of disaggregated planetary boundaries, doughnut economics framework, Inner and Outer transformation, and Bend-the-Curve gamification, the impacts of each type of operation can be measured.

    2. A guiding principle will be to make the hyper-response as not only fun and enjoyable as possible but also meaningful via a vibrant grand narrative approach that connects the mission to conceptions of identity, values, and evolving worldviews.

      Gamification will play a critical role to tap into the human psychology that will encourage proactive action. Bend-the-Curve is the glocal game proposed as a way to mobilize ordinary citizens aggregate community scale response teams.

      As part of this gamification, a private Transform application within the public and open Indyweb can facilitate individual inner transformation, synchronize that to individual outer (behavior) transformation and synchronize that to collective inner and outer transformation at the respective community collective scale and finally aggregating all community impacts, to the global collective transformation scale. Built in data privacy of the Indyweb insures that everyone can contribute data to the aggregator in a completely anonymous way. All of this is designed to operationalize Donella Meadow's insight that inner transformation of worldviews, paradigms and value systems is the most powerful of all leverage points.

    3. For four years, an accelerated and intensive global effort will be made to reduce greenhouse gas emissions and restore ecological stability. It will be “fast and furious” because it will involve startup action as well as implementation. It is focused on the remaining “low-hanging fruit” for fastest global reductions

      The Tipping Point Festival can introduce the Bend-the-Curve (BtC) gamification to engage as many cities, towns, rural communities and bioregions as possible. A 3 year research program to dis-aggregate planetary boundaries can allocate a fairshare of local biophysical targets each city, town, rural community and bioregion must aim to achieve if we as a civilization are to meet the 1.5 deg C target, as well as other Anthropocene and planetary boundary targets.

      Doughnut economic framework can be adopted immediately and educated across all communities to plant seeds of local change actor chapters who can start their own local doughnut economies and begin reshaping their local economy into circular bio WEconomies.

      When the dis-aggregated planetary boundary metrics are available, then each community can adopt and aim to bend their local curve, in order that we altogether bend the global curves back to a safe operating space.

      it may be questionable whether we are able to develop highly accurate targets, but even if we are close enough, the greater value is to allow citizens to have a tangible and compelling and measurable reason to work together, organize and mitigate our human impacts in a systematic way. In this way, we can expose the hyperthreat by breaking it down into digestable, identifiable pieces that are cognitively more accessible and can lodge into the salience landscape of the individuals of a community.

    1. Secondly, the difficulty ramps up very quickly - once I'd got a handle on things and started getting in to it, it threw me off that the Novice level 7 is just WAY TOO HARD - it's not a game centered on difficulty so it's not like that's an excuse, nor is this a later on level where you'd except difficulty, but having just 15 seconds to do that lap, that needs to be changed to 20 at least!
    1. If you like puzzle games, this is certainly a game for you. Well designed level progression that helps you build a good understanding of the underlying rules of the world
    1. Motivation is provided by an ever-escalating difficulty, though not to the point where you feel frustrated.
    1. There were a few times I felt like making notes, but never ended up needing to because the scale of the puzzles is kept manageable throughout.

    1. TheIndustrial Revolution isthe first strong historical analog for the modern phenomenonof a quantum leap in human progress, resulting in radically altered ways of life in a short span of time.

      As Hall points out in Where Is My Flying Car? there is a strong argument to be made that the industrial revolution was a social chain reaction that had already set off an exponential improvement process on its way to 'singularity', this was disrupted in the 20th century however. But prior to that it had been ongoing for 300 years at a steady average rate of 7% more usable power annually.

    1. Jeff Sonnabend in the Ecco Yahoo forum: "I remember first trying to learn Ecco 1.0. It was tough until the proverbial light went on. Then it all made sense. For me, it was simply understanding that Ecco is just a data base. So called folders are nothing more than fields in a flat-file table (like a spreadsheet). The rest is interface and implementation of various users' work or management systems in Ecco. That learning curve, to me, is the primary Ecco "weakness", at least as far as new users go."

      There was a steep learning curve involved with using ECCO Pro. Reminds me of Roam, which also has a steep learning curve, but then it feels like it's worth it.

    1. the lowest copy number sample points impacted faster and sronger, then you just need to stabilize by adding a neutral nucleic acid background in your standard curve. I usually use water containig 10ng/microl yeast tRNA to perform serial dilutions. This will first create a reaction background similar to your RTQPCR reaction, but also stabilize your DNA copies; I can freeze and thaw (min 20C) more than 50 times the same standard curve sample without any loss in Cts, from 10E6 to 10E2 copies. When I tested the same standard curve but diluted in water only, then the 10E2 started to be slightly affected after one freeze and thaw and then crashed further; then higher copy numbers samples were also affected after 2 to 3 freeze and thaw.

    1. Such languages may make it easier for a person without knowledge about the language to understand the code and perhaps also to learn the language.
    1. Did you expect the temp directory to get printed? In the last example, we saw the directories ./temp and ./C/temp got printed, but not now. This is the effect of the -print option. By default, the find command prints all the files matching the criteria. However, once the -print option is specified, it will print files only on explicit print instructions. In this find command, -print is associated in the other side of the OR condition, and hence nothing will get printed from the 1st part of the condition.

    1. Might be a little too low-level (even with GUIs) for some teams of users. GPG and Git both require some setup and experience in these tools, or the willingness to learn. Porting a GPG key from machine to machine is not trivial.

    1. Sidenote: Visually comparing estimated survival curves in order to assess whether there is a difference in survival between groups is usually not recommended, because it is highly subjective. Statistical tests such as the log-rank test are usually more appropriate.
    1. Note that, the confidence limits are wide at the tail of the curves, making meaningful interpretations difficult. This can be explained by the fact that, in practice, there are usually patients who are lost to follow-up or alive at the end of follow-up. Thus, it may be sensible to shorten plots before the end of follow-up on the x-axis (Pocock et al, 2002).

    1. The Grid is based around ideas familiar to Bitwig Studio

      The continuity between these new modular features and the rest of the DAW’s workflow probably has unexpected consequences. Before getting information about BWS3, one might have thought that the “Native Modular System” promised since the first version might still be an add-on. What the marketing copy around this “killer feature” makes clear, it’s the result of a very deliberate process from the start and it’ll make for a qualitatively different workflow.

    1. Some readers will also be surprised to find that The Bell Curve is not as controversial as its reputation would lead one to believe (and most of the book is not about race at all).

      I wrote this sentence. Two coauthors, three peer reviewers, and an editor all read it multiple times. No one ever asked for it to be changed.

    1. I think this paper and these data could be extremely useful for psychologists, but I also think this paper needs at least one more analysis: estimating effect sizes by research area, controlling for publication bias.

      It's very hard to interpret these estimates given good evidence and arguments that researchers and journals select for p < .05. I think it's safe to assume that all these estimates reported in this preprint are bigger than the true averages (Simonsohn, Nelson, & Simmons, 2014).

      One approach to estimating "selection bias adjusted" effects would be to estimate the effect size for each research area using the code provided in the p-curve effect size paper supplements (http://www.p-curve.com/Supplement/). You could estimate confidence intervals or percentiles using bootstrapping procedures or write code to estimate the lower and upper bounds using the same methods to estimate the average effect.

      This approach assumes the p-values all test the hypothesis of interest and don't suffer from unique selection biases (see Selecting p Values in Simonsohn, Nelson, & Simmons, 2014, p. 540).

      Hope this helps make the paper better!
