    1. Communities of practice are one of the ways in which experiential learning, social constructivism, and connectivism can be combined, illustrating the limitations of trying to rigidly classify learning theories. Practice tends to be more complex.
      • Constructivism - roots in the philosophical and psychological viewpoints of this century, specially Piaget, Bruner and Goodman. Learning occurs when the mind filters inputs from the world to produce its unique reality. The mind is believed to be the source of all meaning, direct experiences with the environment are considered critical. It crosses both categories by emphasizing the interaction between learner and the real world.

      • Social constructivism would emphasize critical experiences between the learner and other learners and mentors.

      • Connectivism is the integration of principles explored by chaos, network, complexity and self-organization theory. A lot of the content is now offloaded to the machine that was previously residing within the learner.

    1. Connectivism is the theory behind massive open online courses, MOOCs

      the author doesn't really elaborate as to how or why connectivism is the guiding theory behind moocs.

    1. As elaborated below, these decisions regarding both the medium and production encourage engage-ment, as they facilitate the creation of sequel imitations

      The unprofessional/amateur medium actually encourages further interaction as it is indicative of a "lower bar" to clear in order for further engagement to occur.

    1. n other words, each amount of sharing activity by likely bots tends to trigger a disproportionate amount of human engagement.

      Bot intervention increases human interaction with online content

    1. Giddens argues that social action is linked directly to the creation of rules and practices which recursively constitute the structure wherein social action takes place.

      Social interaction is recursive--meaning that it loops in on itself, the act of social interaction a symptom and a cause of social interaction

    2. Whereas a cultural artifact offers information about the culture that creates and uses it (Watts, 1981), a social artifact informs us about the social behavior of those individuals or groups which produce it (

      Provide information about behaviour and communication rather than about a tradition or a specific practice.

    3. a genre with its own set of rules and conventions and a genre whose production is a product of postmodern conceptions of representation and replication (Baudrillard, 1994) and the obfuscation of the consumer/producer binary which is manifest in the practices of participatory culture (Jenkins, 2007)

      New conception of how media is spread and a new conception of ownership of content and how much it matters.

    1. 这样启动时不需要和 Zookeeper 通讯获取 Worker ID. 做到了完全的去中心化

      分布式网络内的 workerid 有些情况下是通过一个中心服务器分配的

      如果我们使用 mac 地址,或者其它机器自身唯一属性作为 workerid,则可实现去中心化

    2. snowflake生成的ID整体上按照时间自增排序,并且整个分布式系统内不会产生ID碰撞(由datacenter和workerId作区分),并且效率较高。这个算法单机每秒内理论上最多可以生成1000*(2^12),也就是400W的ID。

      41位毫秒时间戳 10位机器编号 12位毫秒内序列号

      单机 12位毫秒序列号 1 毫秒内最多生成 2^12 = 4096 个

      单机 1 秒内最多生成 409.6w 个

    1. Internet memes are a digital version of Dawkins’ (1976) idea of memes, defined as individual bits of cultural information that propagate from person to person while undergoing variation, selection, and retention. Memes are transmitted throughout a population via social learning, and at any given time, members of a population either are adopting cultural traits (which become memes) or rejecting those traits through a complex interplay of social, emotional, and cognitive processes (Baker & Gammon, 2008).

      So, this definition mentions Dawkins but it does seem mor focused on the communication aspect of memes.

    2. This Emotional Selection Hypothesis

      Meaning that we select our communication based upon the emotional impact it will have?

    3. When one is embedded within an existing network of likeminded individuals

      Affinity space?

    1. Birds of Prey

      This is a Petrarchan sonnet. The rhyme scheme is ABBAABBACDCDCD. Petrarch is the creator of the Italian sonnet and the sonnet in general.

    2. Birds of Prey

      Peregrine Falcons are the largest falcon over most of the continent. The can be found all around north america. They have long pointed wings with a long tail.

    1. Textual tags were manually assigned. The tags were used to identify the main action or point of the meme

      How was this "main point" determined?

    2. Memes were provided a categorical tag based on visual content. This tag provided a textual representation of the image even if the image had no embedded textual phrases

      Holland's tags~

    3. Humor is an interesting emotional category that contains a vast array of sub-categories.

      Wow, much insight my dude

    1. 8. Examples 8.1. Hello World! The following ni URI is generated from the text "Hello World!"

    1. A URI identifies a resource either by location, or a name, or both. A URI has two specializations known as URL and URN. A Uniform Resource Locator (URL) is a subset of the Uniform Resource Identifier (URI) that specifies where an identified resource is available and the mechanism for retrieving it.URL defines how the resource can be obtained. It does not have to be HTTP URL (http://), a URL can also be (ftp://) or (smb://) A Uniform Resource Name (URN) is a Uniform Resource Identifier (URI) that uses the URN scheme, and does not imply availability of the identified resource. Both URNs (names) and URLs (locators) are URIs, and a particular URI may be both a name and a locator at the same time.
    1. Although there are plenty of theories which could all be modelled, because the extant theory is so heavily based on assumptions which would have to be built into the models to make them work, they could all show interesting results which are, however, devoid of any resemblance to how culture actually happens

      Too many theories but enough agreed upon assumptions to create a model that could actually be applied nor a model that would accurately represent some aspect of reality.

    2. The resulting materialistic theory of consciousness2, where a „pandemonium‟ of various thoughts and nerve impulses struggle for expression, posits that what we comprehend as a serial stream of consciousness is actually a retrospectively experienced stream of narrative which was subject to continual editing as the various areas of the brain made their contributions.

      There is no photogrpahic memory for most people; every memory is being continuously edited in the mind,

    3. Rather, it is the usual practice to selectively pick examples from culture to help illustrate how memes may work and therefore convenient memes tend to be invoked to help description rather than candidates for real memes discovered in their cultural settings

      Only pragmatic examples

    1. As an example, one of the most significant problems in healthcare security is the need for users to authenticate quickly to shared workstations in clinical environments. I could see a future version of Face ID embedded in an iMac solving that problem, changing an entire industry, and selling a lot of iMacs!

      Sounds very unlikely.

    1. to prove this, let facts be submitted to a candid world, for the truth of which we pledge a faith yet unsullied by falsehood.

      The Declaration of Independence impacted the United States in more ways than one, Jefferson makes clear when he states "to prove this, let facts be submitted to a candid world;" he is referring to the reign of the King of Great Britain who has brought injuries and tyranny over the states. He wants his people to realize the corruption and wrongdoings that the king has caused. Jefferson is essentially saying that people should be uncorrupt in this new world and man should strive to preserve the pureness of this country keeping it from falsehood and injustice. It sparked my attention when I came across a newspaper titled "The North Briton" written by J. Wilkes and others which contained very similar diction and ideals of society during that time period. Wilkes is criticizing King George III for his speech in favor of the Treaty of Paris ending the Seven Year’s War; he states “Articles 15 is for having corrupted the sacred fountain of truth and put falsehoods into the mouth of Majesty, in several speeches made in parliament.” Wilkes is trying to uncover the king’s corruption and bring to light that he is lying to his people which ties closely to Jefferson’s actions and morals of being uncorrupt. Most people carried similar beliefs in the United States during the 18th century, it is very possible that the Wilkes could have been from Jefferson's era carrying the same ideals and values as him due to similar style of writing, choice of diction, and beliefs.

It sparked my attention when I came across a monthly chronologer titled "The Gentleman's and London magazine" that contained very similar diction and ideals of society during that time period. It is noticed that humans are habitual creatures and mimic their peers within their society creating a universal diction within that community. Most people carried similar beliefs in the United States during the 18th century since most citizens were of Christian faith it is very possible that the writers of the "Gentleman's and London Magazine" could have been from Jefferson's era having the same ideals and values as him due to similar style of writing and choice of diction.
