    1. The gambler's fallacy, also known as the Monte Carlo fallacy or the fallacy of the maturity of chances, is the erroneous belief that if a particular event occurs more frequently than normal during the past it is less likely to happen in the future (or vice versa), when it has otherwise been established that the probability of such events does not depend on what has happened in the past. Such events, having the quality of historical independence, are referred to as statistically independent. The fallacy is commonly associated with gambling, where it may be believed, for example, that the next dice roll is more than usually likely to be six because there have recently been fewer than the usual number of sixes.
    1. Though rarer in computer science, one can use category theory directly, which defines a monad as a functor with two additional natural transformations. So to begin, a structure requires a higher-order function (or "functional") named map to qualify as a functor:

      rare in computer science using category theory directly in computer science What other areas of math can be used / are rare to use directly in computer science?

    2. A combinator, typically called bind (as in binding a variable) and represented with an infix operator >>=, that unwraps a monadic variable, then inserts it into a monadic function/expression, resulting in a new monadic value:(mx >>= f) : (M T, T → M U) → M U
    1. What is the opposite of free content?

      The opposite of free/open-source software is proprietary software or non-free software (https://en.wikipedia.org/wiki/Proprietary_software).

      So should we call the opposite of free content "non-free content"? Or "proprietary content"?

      Seems likes either would be fine.

      Looks like https://en.wikipedia.org/wiki/Wikipedia:Non-free_content prefers the term "non-free content".

      Couldn't find anyone contrasting these 2 terms (like I could no doubt find for software):

      Not to be confused with:

      • paid content ... just like:
      • free content should not be confused with gratis content (?)
      • free software should not be confused with freeware
    2. A free cultural work (free content) is, according to the definition of Free Cultural Works, one that has no significant legal restriction on people's freedom to: use the content and benefit from using it, study the content and apply what is learned, make and distribute copies of the content, change and improve the content and distribute these derivative works.
    1. Bert Haanstra(伯特·汉斯特若)的这部记录片让人忍不住感叹,想象力从来不曾被时间所束缚。最奇妙的是,全片没有任何解说和旁白。

      但在导演神乎其技的剪辑之下,背景的爵士小调与工匠吹玻璃时的节奏配合的天衣无缝,当工匠们鼓起腮帮子,你会分不清他们是在吹奏小号还是在吹制玻璃。

      在这部11分钟的短片中,工匠精湛灵巧的手艺和机械的流水线生产形成了鲜明的对比,工匠一拉一提就是一个玻璃制品,价值不言而喻。Bert Haanstra把玻璃工艺拍的如此诗意,在1960年,不负众望获得了第32届奥斯卡最佳纪录短片奖。

    1. He picked himself for the match so as to fulfill the BCCI criterion (which requires state administrators to have at least one first-class match experience) for becoming a selector at the state level. After the match, he appointed himself as the chairman of selectors of HPCA Ranji trophy cricket team

      Wow! smells like conflict of interest, ain't it?

    1. The Indie-Verse was an internet audio station based in Dallas, Texas that served the Dallas/Fort Worth Metroplex as well as all of the United States through its internet presence with a diverse alternative & indie music format. It was also broadcast on KJKK 100.3 HD-3 (HD Radio needed) and was under ownership of CBS Radio. The name was a portmanteau of "Indie", short for "independence" or "independent"; and "Universe".

    1. Kundalini (Sanskrit: कुण्डलिनी kuṇḍalinī, pronunciation (help·info), "coiled snake") is a form of divine feminine energy (or shakti) believed to be located at the base of the spine, in the muladhara.

      so is there multiple types of shakti energy? and is it always a divine female energy? what makes it divine female energy vs male or some type of both genders

    1. 埃丝特·迪弗洛(Esther Duflo)创立的贾米尔贫困行动实验室(Jameel Poverty ActionLab, 下文简称J-PAL )拥有近百位隶属教授,近五百个科研项目。

      五百个项目的全部内容: “随机对照试验”(randomized control trials,下文简称RCT)。

      要测试一个政策到底有没有效,就把参与者随机分为两组,一组进行政策干预,一组做对照,两组之间的差异就是政策产生的效果。

      为什么RCT如此红火?

      1. 它简单易懂。相比较其他复杂的微观方法,RCT显然更能让经济学的门外汉们明白。
      2. 在许多国家,由于资金的缺乏,福利政策往往不能落实到所有穷人,这反而促成了RCT。既然钱不够发,注定有些穷人可以拿到救济,而有些穷人拿不到,那为什么不把发放的过程随机一下,顺便测试一下政策的效果呢?
      3. 数据说话,评估结果不太容易推翻。直接效应是,这样的评估能够比较公正地说明一个政策的效用,不会轻易被政治左右。
      4. 诸如世界银行、USAID这样庞大的援助机构建立多年,耗费巨大资金,而世界贫困的现状并未显著改善。境外援助有用吗啊?什么样的援助项目最有用?为了回答这样的问题,RCT成了好用的工具。

      中国目前最大的致力于RCT的机构是斯坦福大学旗下的“农村教育行动计划”(Rural Education Action Project,简称REAP)。

    1. The eyes of the Fair are on the future—not in the sense of peering toward the unknown nor attempting to foretell the events of tomorrow and the shape of things to come, but in the sense of presenting a new and clearer view of today in preparation for tomorrow

      The importance of looking ahead but not trying to predict the future

    1. The most notable characteristic in a scale-free network is the relative commonness of vertices with a degree that greatly exceeds the average. The highest-degree nodes are often called "hubs", and are thought to serve specific purposes in their networks, although this depends greatly on the domain.

    1. For the usage in society, see Second-class citizen.
      1. Ironic that this reference is ostensibly about the usage of "first-class citizen" in society, yet it links to a seemingly-mismatched (by name only, that is) article, entitled "second-class citizen".

      2. Ironic that the first-class (unqualified) article is about the figurative meaning of "citizen" used in computer science, and that the page describing first-class and second-class status of the more literal citizens in society is relegated to what I kind of think is a second-class position in the encyclopedia (because it takes the #2 position numerically, even though it is (at least as is implied in this reference) also about first-class citizens (though the word "first-class" does not appear a single time in that article, so maybe this reference is the one that is more ironic/incorrect).

    1. In object-oriented programming, information hiding (by way of nesting of types) reduces software development risk by shifting the code's dependency on an uncertain implementation (design decision) onto a well-defined interface. Clients of the interface perform operations purely through it so if the implementation changes, the clients do not have to change.
    1. The Chicago Manual of Style and the Associated Press (AP) both revised their formerly capitalized stylization of the word to lowercase "internet" in 2016.[3] The New York Times, which followed suit in adopting the lowercase style, said that such a change is common practice when "newly coined or unfamiliar terms" become part of the lexicon.
    1. With the introduction of CPUs which ran faster than the original 4.77 MHz Intel 8088 used in the IBM Personal Computer, programs which relied on the CPU's frequency for timing were executing faster than intended. Games in particular were often rendered unplayable. To provide some compatibility, the "turbo" button was added. Engaging turbo mode slows the system down to a state compatible with original 8086/8088 chips.
    1. while it is strongly NP-complete if the weights and profits are given as rational numbers.[12] However, in the case of rational weights and profits it still admits a fully polynomial-time approximation scheme.

    1. 在法国劳塞尔岩洞中发现的浮雕“持牛角的少女”,又被称为“持角杯的维纳斯”。

      法国劳塞尔的岩洞中发现的一座公元前30000年的石灰石浮雕上,一位体态丰满的女性,一只手托着一个牛角,而另一只手则抚摸着自己圆润隆起的腹部,它的寓意真是太明显了:旺盛的生命力通过手中的牛角传递到自己的腹部,她将会诞育出新的生命。当然,如你所想的那样,这座浮雕上也涂上了象征生命力的赭红色。

    1. On different servers (instances), users can create so-called identities. These identities are able to communicate over the boundaries of the instances because the software running on the servers supports one or more communication protocols which follow an open standard

    2. The Fediverse (a portmanteau of "federation" and "universe") is an ensemble of federated (i.e. interconnected) servers that are used for web publishing (i.e. social networking, microblogging, blogging, or websites) and file hosting, but which, while independently hosted, can communicate with each othe

    1. A successful evaluation of discriminant validity shows that a test of a concept is not highly correlated with other tests designed to measure theoretically different concepts.

      But what if the traits you are trying to measure are actually correlated in the real world?

    1. The remaining term, 1 / (1 − Rj2) is the VIF. It reflects all other factors that influence the uncertainty in the coefficient estimates. The VIF equals 1 when the vector Xj is orthogonal to each column of the design matrix for the regression of Xj on the other covariates. By contrast, the VIF is greater than 1 when the vector Xj is not orthogonal to all columns of the design matrix for the regression of Xj on the other covariates. Finally, note that the VIF is invariant to the scaling of the variables

      VIF interpretation

    2. It turns out that the square of this standard error, the estimated variance of the estimate of βj, can be equivalently expressed as:[3][4] var ^ ( β ^ j ) = s 2 ( n − 1 ) var ^ ( X j ) ⋅ 1 1 − R j 2 , {\displaystyle {\widehat {\operatorname {var} }}({\hat {\beta }}_{j})={\frac {s^{2}}{(n-1){\widehat {\operatorname {var} }}(X_{j})}}\cdot {\frac {1}{1-R_{j}^{2}}},} where Rj2 is the multiple R2 for the regression of Xj on the other covariates (a regression that does not involve the response variable Y). This identity separates the influences of several distinct factors on the variance of the coefficient estimate: s2: greater scatter in the data around the regression surface leads to proportionately more variance in the coefficient estimates n: greater sample size results in proportionately less variance in the coefficient estimates var ^ ( X j ) {\displaystyle {\widehat {\operatorname {var} }}(X_{j})} : greater variability in a particular covariate leads to proportionately less variance in the corresponding coefficient estimate The remaining term, 1 / (1 − Rj2) is the VIF. It reflects all other factors that influence the uncertainty in the coefficient estimates

      a useful decomposition of the variance of the estimated coefficient

    1. Interesting topic. On the surface there is an Investigative Reporter in a common activist role. He had a Heroin problem and hacktivist ties which certainly did not help his situation.

      • Stratfor gets hacked by Jeremy Hammond ,
      • Hammond, a part of LulzSec leaks all to Wikileaks
      • Brown, with ties to LulzSec most likely combs through the leaked data
      • Brown is subjected to what appears to be excessive LE abuse and manipulation
      • Brown is reported to have threatened an FBI Agent via YouTube.....ok.....and this is the reason for additional charges and outrageous sentencing recommendations.
      • WHY...is Brown subjected to this type of treatment and President Donald Trump gets away with far worse?
    1. Although influenced by the works of Classical Antiquity, Nicola was not simply an imitator. His figures are original creations that came into being through a thorough study and understanding of the antique prototypes and the reinstating of antique representations.

    3. Italian sculptor whose work is noted for its classical Roman sculptural style. Pisano is sometimes considered to be the founder of modern sculpture.[2]

      Important ideas

    1. Filippino depicted his characters in a landscape which recreated the ancient world in its finest details, showing the influence of the Grottesco style he had seen on his time in Rome.

      Important ideas

    1. Vasari knew Sebastiano, but probably not very well; although he had been compiling material for some time, the first edition of his Lives did not appear until 1550, after Sebastiano's death, and it is not clear if he had specifically discussed the biography with Sebastiano.

      Names/important ideas

    2. "As so often with Sebastiano's drawings, the first impression is one of unrhythmic dryness; but the suggestion of atmosphere, the sensitively drawn contemplative faces and the subtle use of reflected lights and tonal transitions leave no doubt that [this] is from his own hand.

      Important ideas

    3. From early on he was innovative and ready to experiment in compositional details as well as technique, with a special interest in painting in oils on new surfaces, whether plaster, stone, alabaster or slate.

      Important ideas

    4. Vasari, probably much influenced by Michelangelo, places great emphasis on Sebastiano's turning away from art for a comfortable life as a well-paid courtier from this point, but may overstate the reality

      Important ideas

    5. following years Sebastiano mostly avoided very large commissions for churches, and concentrated on portraits, where he had a considerable reputation, and religious easel paintings, such as his Visitation for France (1518–19, now Louvre),[30] and his Madonna of the Veil
