    1. when we're being we're talking across difference is to stand in the other person's standpoint it's to ask the other person in three separate ways in three 00:30:13 different kinds what am I missing here tell me more about your point of view tell me more tell me more tell me more and if you ask them three or four times in different ways you'll be astonished how the third and fourth answer is 00:30:25 deeper richer and more complicated than the first first answer

    1. we weren't gifted with that virtuous extra-caring that prominent altruists must have

      what if new generations could be better at this? and they don't know how to assume?

    2. learned not to trust their care-o-meters

      I would say "train our internal care-o-meter" instead of living against it

    3. caring about the world isn't about having a gut feeling that corresponds to the amount of suffering in the world, it's about doing the right thing anyway. Even without the feeling.

      our brain can bypass moral feelings in multiple ways. Our moral feelings are produced by the brain?

    4. instead of just asking his gut how much he cares about de-oiling lots of birds, he shuts up and multiplies.

      what else could we do if we train our brain to ignore the feeling and just act on numbers?

    1. Theories of change that focus solely on overturning current societal structures generally lack concreteness

      In my opinion, it is nearly impossible for any individual to completely understand and exert complete control over the entire world. Rather, the world progresses through a collective effort shaped by countless individuals. This implies that no one person can directly alter the overall direction, but over time, with sufficient influence, the direction can indeed be subject to change.

    2. if they live in a high-income country, even an average person earning a modest salary is often wealthy compared to the rest of the world

      "What about wealth beyond income? If you have a family without assets or inheritance, and your only source of support is your salary, should you invest in a home to safeguard your family when you can no longer work? How do you manage the high cost of living in wealthy countries? For many families, their entire financial stability relies on their ability to work. Moreover, what can be done about the increasing living costs that surpass income growth? And how do we address jobs with poor conditions that cannot be sustained until retirement?"

    1. In the new collection, The Good It Promises, The Harm It Does, activists and scholars address the deeper problems that EA poses to social justice efforts. Even when EA is pursued with what appears to be integrity, it damages social movements by asserting that it has top-down answers to complex, local problems, and promises to fund grass-roots organizations only if they can prove that they are effective on EA’s terms.
    2. Despite the liberating intentions of many of its advocates, EA is, irredeemably conservative.  It favors welfare-oriented interventions that increase countable measures of well-being and both neglects and diverts funds from social movements that address injustices and agitate for social change, particularly in marginalized communities both in the US and in the Global South.

    1. Much of what they do can be done without eliciting the ire of nation-states. Bike shares, pedestrian zones, insulated buildings, renovated port facilities, congestion fees, car emission limits, furnace specifications, fuel upgrades (from oil to gas to alternative energy) and white paint roofs, for example, are only some of the innovations city officials can promote to effect significant reductions in emissions and pollutants.

      !- cities actions : can be done without eliciting ire of nation state - bike shares - pedestrian zones - insulated buildings - renovated ports - congestion fees - car emission limits - furnace specifications - fuel upgrades - white paint roofs - cities are the right level for focusing on effective global climate action

    2. here states have grown dysfunctional and sovereignty has become an obstacle to global democratic action—as when the United States (or China, France, or Canada) refuses to compromise its sovereignty by permitting the international monitoring of carbon emissions on its soil—cities have increasingly proven themselves capable of deliberative democratic action on behalf of sustainability, as they have actually done in intercity associations like the C-40 or ICLEI. If presidents and prime ministers cannot summon the will to work for a sustainable planet, mayors can. If citizens of the province and nation think ideologically and divisively, neighbors and citizens of the towns and cities think publicly and cooperatively.

      !- claim : cities can mitigate corrupted democracy and foster global cooperation - ie. C40 or ICLEI (also Covenant of Mayors) - cities are not plagued by the problems of state actors who cannot reach any meaningful agreement at COP conferences

    1. You’re walking to work and you see a burning mansion. You’ve been in that mansion and know that there’s a Picasso worth $100 million. (Quick math: 100,000 lives saved.) You’re about to run into the mansion to save the Picasso…But right next to you, there’s a lake. And in that lake, there’s a drowning child.

      not all good actions can necessarily be quantified.

    1. he um belt has two sides to it which are not separable in german they're the merkveld and the virgvelt the merkwelt is the umvelt considered 00:19:24 from the aspects of semiotics or signs or meaningful stimuli things to differentiations one might draw distinctions one might draw that are available to one the virgvelt is the same thing 00:19:37 considered under a different aspect which is the space of possible effective actions to draw a distinction is now to move in knowledge of that distinction 00:19:49 this notion of the virgvelt will will appear later in ecological psychology with the notion of affordance and and again a concept that follows totally nails long before it appears in the literature 00:20:02 so when you hear umwelt try not to think entirely visually but to recognize that we we're dealing here with a concept which must be understood as a sort of a stereoscopic fusion 00:20:14 of the idea of meaningful appearance meaningful showing up and capacity for action because of the difficulties in disciplining this view of this emerging 00:20:28 view of the subject you won't find it easy to interpret vulnerability in terms of personal experience he vacillates here and our vocabulary is still not great here but the umvelt has 00:20:40 this important character of being neither a theory of perception or theory of action in keeping with all embodied theories later perception and action are absolutely indistinguishable but we can characterize them in this 00:20:53 with this dual aspect manner so when you encounter sketches like this he's full of bold imaginative sketches in his work

      Uexkull decomposes the umwelt into two parts: 1. merkwelt (signs) 2. wirkwelt (effective action)

    1. So I was thinking about the brief conversation we'd had about [[effective altruism]], and I started writing, and I wrote a lot, so my preamble is that I mean here to put words to a seed of a heuristic I'm working with, not just criticize. But I don't really have a clean phrase for the topic... so I'm tossing this in my daily note, and maybe it'll make sense to move later?

      Thank you so much, this is awesome [[maya]]!

    1. It is also related to the EA movement in that, despite no official relationship between SFF and EA, despite the person who runs SFF not considering himself an Effective Altruist (Although he definitely believes, as I do, in being effective when being an altruist, and also in being effective when not being an altruist), despite SFF not being an EA organization, despite the words ‘altruist’ or ‘effective’ not appearing on the webpage, at least this round of the SFF process and its funds were largely captured by the EA ecosystem. EA reputations, relationships and framings had a large influence on the decisions made. A majority of the money given away was given to organizations with explicit EA branding in their application titles (I am including Lightcone@CFAR in this category). 

      Indeed. Because the people funding it think like that. They are in a given worldview.

    2. Whether or not they would consider themselves EAs as such, the other recommenders effectively thought largely Effective Altruist frameworks, and seemed broadly supportive of EA organizations and the EA ecosystem as a way to do good. One other member shared many of my broad (and often specific) concerns to a large extent, mostly the others did not. While the others were curious and willing to listen, there was some combination of insufficient bandwidth and insufficient communicative skill on our part, which meant that while we did get some messages of this type across on the margin and this did change people’s decisions in impactful ways, I think we mostly failed to get our central points across more broadly.

    1. A recent survey found that only 14% of people they surveyed in the United States talk about climate change. A previous Yale study found that 35% either discuss it occasionally or hear somebody else talk about it. Those are low for something that over 70% of people are worried about.

      Conversation is not happening! There is a leverage point in holding open conversations where we understand each other’s language of different cultural groups. Finding common ground, the common human denominators (CHD) between polarized groups is the lynchpin.

    1. Using evidence and reason to find the most promising causes to work on. Taking action, by using our time and money to do the most good we can.

      I think I learned about effective altruism through Ezra Klein and the Future Perfect podcast.

    1. human beings started to take control of human evolution; that we stood on the brink of eliminating immeasurable levels of suffering on factory farms; and that for the first time the average American might become financially comfortable and unemployed simultaneously

    1. The Virginians needed labor, to grow corn for subsistence, to grow tobaccofor export. They had just figured out how to grow tobacco, and in 1617 theysent off the first cargo to England. Finding that, like all pleasurable drugstainted with moral disapproval, it brought a high price, the planters, despitetheir high religious talk, were not going to ask questions about something soprofitable.

      Told from this perspective and with the knowledge of the importance of the theory of First Effective Settlement, is it any wonder that America has grown up to be so heavily influenced by moral and mental depravity, over-influenced by capitalism and religion, ready to enslave others, and push vice and drugs? The founding Virginians are truly America in miniature.

      Cross reference: Theory of First Effective Settlement

      “Whenever an empty territory undergoes settlement, or an earlier population is dislodged by invaders, the specific characteristics of the first group able to effect a viable, self-perpetuating society are of crucial significance for the later social and cultural geography of the area, no matter how tiny the initial band of settlers may have been.” “Thus, in terms of lasting impact, the activities of a few hundred, or even a few score, initial colonizers can mean much more for the cultural geography of a place than the contributions of tens of thousands of new immigrants a few generations later.” — Wilbur Zelinsky, The Cultural Geography of the United States, Englewood Cliffs, NJ: Prentice-Hall, 1973, pp. 13–14.

    1. In order to combat these form spam BOTS, websites often employ a series of textual or picture quizzes to the user submitting the form such as CAPTCHA. These tests are somewhat effective for standard BOTS, but are annoying to website visitors and often lead to abandoned contacts or site sales. In addition, BOTS are evolving to the point where these measures are becoming obsolete and ineffective.

    1. Adult enrollment in higher education grew by more than 50 percent between 1991 and 2011, according to U.S. News & World Report. This trend shows that today’s educators and corporate trainers must adapt to the different needs, learning styles and challenges presented by teaching adult students. By understanding adult students, you can become a better educator or trainer. Here are six key teaching strategies for making lessons more applicable for adult learners. Keep It Relevant Adult students truly latch onto lessons they feel are relevant. They have to understand how the skills they learn will improve their daily lives. If they believe a lesson will have a measurable impact, they will be far more likely to be engaged and internalize the lesson. How can this be achieved? Education resource eLearning Industry recommends considering the “real value in the educational experience you’re providing.” While teaching adults, educators and trainers should consider the real-world impact on how a person works or interacts with  family. Remind adult students that a math lesson can help them better understand what they do every day or that the course will give them the experience they need to advance in their careers. Real-world outcomes will inspire an adult student to put forth more effort in a course. Remember Student Backgrounds One of the many differences between adult learners and their younger counterparts is experience. Adult education has to draw on the fact that stu

      Adults going back to further their education has grown by 50 percent between 1991 and 2011! With these staggering numbers, educators must remember 6 effective strategies for teaching adults. The 6 strategies are:

      1. Keep it Relevant
      2. Remember Student Background - adult learners have far more experience and more background.
      3. Integrate Emotion into Lessons - helps students to connect.
      4. Encourage Exploration - didactic teaching - allowing activities and assignments to stay static but topic to be explored.
      5. Make Assignments Convenient - With more people working, assignments need to be broken into smaller more manageable parts.
      6. Always Offer Feedback- The quicker feedback the better! Rating 8/10

    1. Thinking in Multimedia: Research-Based Tips on Designing and Using Interactive Multimedia Curricula.

      This article examines various methods of delivery: multimedia integration, possibly including audio, video, slides, and animation. The recommendation is to carefully consider which online delivery mode matches with the learner, and to be cognizant that not everyone learns in the same manner. Certain topics may be best presented in live videos and not in power-point slides show as meaning may be lost or not delivered correctly. It’s important to follow-up with immediate assessment and feedback to continue to develop effective training.

    1. It would be unethical, for example, to include as an author someone who had made only minor contributions to the research (e.g., analyzing some of the data) or for a faculty member to make himself or herself the first author on research that was largely conducted by a student.

      This example effectively identifies and communicates what could be a minor contribution to a study as well as an improper behavior regarding the assignment of contribution.

    1. la causeformelle est la causalité des propriétés émergentes

      Dans la définition de la cause formelle, la notion d'émergence introduite ici : "causalité des propriétés émergentes" me paraît centrale. Elle n'est guère reprise (en tant que telle) ailleurs dans le présent article, ni dans celui de Louise. Toutefois, cette question de phénomènes émergents liés aux dispositifs d'éditorialisation permet peut-être d'indiquer certains limites à l'usage des mots "circulaire" ou "récursif" qui semblent à la fois décrire des processus similaires tout en contenant une contradiction interne : un phénomène récursif n'est justement pas circulaire...

    1. DHers need more effective communication with broader publics, to bring our own work in preservation, speculative computing, and cultural memory into the light—and to foster collaborations with people outside the academy who share our orientations and concerns.

      I am in 100% agreement. The question remains; how do you bring DH to the attention of the general public in a relatable and accessible way? How do you bridge the communication gap between those working in DH in an academic capacity and those who know nothing of the concept and work outside of academia?

    1. I will argue that the agonistic relationship between Elizabeth and Charlotte exemplifies competing claims about the development of the person through conjugal intimacy. Ultimately, marriage in Pride and Prejudicebecomes a divisive lens for imagining future selves as well as justifying current happiness.

      Another point of Moe's argument. She contends that marriage and "conjugal intimacy" develops characters differently, based on their opinions on the subject.

    2. Because of Charlotte’s disgraceful attitude toward marriage, “all the comfort of intimacy was over” for the two women (P, 174).

      Moe does an excellent job at providing pivotal quotes from the text to support her characterization of Elizabeth and Charlotte's vastly different opinions on marriage. For an introduction, Moe's explanation of their different views to ground her eventual argument is effective, as it draws the reader in, and establishes the validity of her eventual assertions.

    1. As people age, do you have any advice for them as they get older?

      This is a great question. She obviously planned the interview ahead of time by having good questions ready. She knew what she wanted to learn more about and was sure to ask pointed questions about it. This particular question is interesting since only an elderly person like James can answer it. I think that it is a question that few people think about but everyone is interesting in the answer once they hear it. The interviewer is a great listener and she doesn't assume that she knows the answer even though she knows her grandfather well.

    2. What are the keys to a happy marriage

      This is a big question. She uses the technique of asking easy questions and deeper ones. By asking about things from his past, easy questions and then asks this more philosophical ones, she helps the interview be relaxed but interesting. This is a good technique as far as mixing the more simple and more deep questions.

    1. As far as receiving forgiveness from you–sometimes I still don’t know how to take it because I haven’t totally forgiven myself yet. It’s something that I’m learning from you – I won’t say that I have learned yet – because it’s still a process that I’m going through.

      Without asking any questions, she is able to get Oshea to talk about his feelings by listening well and simply commenting a little based on his responses. This is good, but I think that if she had asked a question or two, it could have been even more interesting. I would suggest a question like: How do you deal with challenges in your daily life? How have you changed since your time in jail? I think that a mix of question/answer and non-planned conversation is the best technique for my interview.

    2. n. I wanted to know if you were in the same mindset of what I remembered from court, where I wanted to go over and hurt you. But you were not that 16-year-old. You were a grown man. I shared with you about my son.

      This is a conversation and not an interview, so it is an interesting comparison with other classic interviews. There are no questions asked, but the two have a history together, so they talk about their relationship. Mary did a good job not answering for him, interrupting or assuming that she knew what he wanted to say since she knew so much about him. This may be helpful to me as I interview my coach, since I will be asking questions, but I can also be open to the conversation. It doesn't have to involve questions only. We can chat about things too.

    1. When you were in jail and I first came out, who was I with?

      This is a good "easy question" that was mentioned in the readings. I see how an easily answered question is good to use, because the interviewee is able to give a lot of detail and will normally get into the conversation more because they know that they have a lot to say on the topic. It opens up the talk and eases the flow, I think.

    2. P: But I wanted to know why you never told me this stuff? Why didn’t you?

      This reveals that Savannah's interview with her mom was motivated by the desire to know more about what happened to both of them and what her mother felt about the circumstances. The first 4 questions definitely felt planned. I think that Savannah wrote them down beforehand, so that she could get specific answers. This shows good planning.

    1. EA principles can work in areas outside of global poverty. He was growing the movement the way it ought to be grown, in a way that can attract activists with different core principles rather than alienating them.
    2. Effective altruism is not a replacement for movements through which marginalized peoples seek their own liberationAnd you have to do meta-charity well — and the more EA grows obsessed with AI, the harder it is to do that. The movement has a very real demographic problem, which contributes to very real intellectual blinders of the kind that give rise to the AI obsession. And it's hard to imagine that yoking EA to one of the whitest and most male fields (tech) and academic subjects (computer science) will do much to bring more people from diverse backgrounds into the fold.
    3. The other problem is that the AI crowd seems to be assuming that people who might exist in the future should be counted equally to people who definitely exist today. That's by no means an obvious position, and tons of philosophers dispute it. Among other things, it implies what's known as the Repugnant Conclusion: the idea that the world should keep increasing its population until the absolutely maximum number of humans are alive, living lives that are just barely worth living. But if you say that people who only might exist count less than people who really do or really will exist, you avoid that conclusion, and the case for caring only about the far future becomes considerably weaker
    4. The problem is that you could use this logic to defend just about anything. Imagine that a wizard showed up and said, "Humans are about to go extinct unless you give me $10 to cast a magical spell." Even if you only think there's a, say, 0.00000000000000001 percent chance that he's right, you should still, under this reasoning, give him the $10, because the expected value is that you're saving 10^32 lives.
    5. At one point, Russell set about rebutting AI researcher Andrew Ng's comment that worrying about AI risk is like "worrying about overpopulation on Mars," countering, "Imagine if the world's governments and universities and corporations were spending billions on a plan to populate Mars." Musk looked up bashfully, put his hand on his chin, and smirked, as if to ask, "Who says I'm not?"

      Es decir, debemos preocuparnos ahora por los riesgos imaginarios de inversiones que ni los gobiernos, ni las universidades están haciendo para un "apocalipsis Sci Fi" un lugar de preocuparnos por los problemas reales. Absurdo!

    1. The rule of thumb is to avoid using more than two expressions in a list comprehension. This could be two conditions, two loops, or one condition and one loop. As soon as it gets more complicated than that, you should use normal if and for statements and write a helper function
    2. Dictionaries and sets have their own equivalents of list comprehen-sions.

      It gets better an better!

      d = { "foo": "bar", "baz": "qux" }
      r = {val: key for key, val in d.items()}
      #=> { "bar": "foo", "qux": "baz" }
      
    3. Unlike map, list comprehensions let you easily filter items from the input list, removing corresponding outputs from the result.

      This might be the greatest advantage of list comprehensions. Even in Ruby requires one to return a nil value from a map and then a call to compact, like: array.map(&:transform).compact.

    4. Beware that indexing a list by a negative variable is one of the few situations in which you can get surprising results from slicing. For example, the expression so melist[-n:] will work fine when n is greater than one (e.g., somelist[-3:]). However, when n is zero, the expression so melist[-0:] will result in a copy of the original list.

      Which is the same for somelist[:]. Not sure what the author is getting at. Maybe he meant to say that using variables as indexes when slicing can become confusing?

    5. Slicing can be extended to any Python class that implements the__getitem__ and __setitem__ special methods
    6. In a file, functions and classes should be separated by two blank lines.

      I wonder what the reasoning for having two blank lines for separating functions and one blank line for methods is. Seems like an arbitrary distinction.
