"Consciousness at its simplest is \"sentience or awareness of internal or external existence\".[1] Despite centuries of analyses, definitions, explanations and debates by philosophers and scientists, **consciousness remains puzzling and controversial,[2] being \"at once the most familiar and most mysterious aspect of our lives\".**[3] Perhaps the only widely agreed notion about the topic is the intuition that it exists.[4] Opinions differ about what exactly needs to be studied and explained as consciousness. Sometimes it is synonymous with 'the mind', other times just an aspect of mind. In the past it was one's \"inner life\", the world of introspection, of private thought, imagination and volition.[5] Today, with modern research into the brain it often includes any kind of experience, cognition, feeling or perception. It may be 'awareness', or 'awareness of awareness', or self-awareness.[6] There might be different levels or \"orders\" of consciousness,[7] or different kinds of consciousness, or just one kind with different features.[8] Other questions include whether only humans are conscious or all animals or even the whole universe. The disparate range of research, notions and speculations raises doubts whether the right questions are being asked.",

"Argument From Consciousness: This argument, suggested by Professor Geoffrey Jefferson in his 1949 Lister Oration states that \"not until a machine can write a sonnet or compose a concerto because of thoughts and emotions felt, and not by the chance fall of symbols, could we agree that machine equals brain.\"[12] Turing replies by saying that we have no way of knowing that any individual other than ourselves experiences emotions, and that therefore we should accept the test. He adds, \"I do not wish to give the impression that I think there is no mystery about consciousness ... [b]ut I do not think these mysteries necessarily need to be solved before we can answer the question [of whether machines can think].\" (This argument, that a computer can't have conscious experiences or understanding, would be made in 1980 by philosopher John Searle in his Chinese room argument. Turing's reply is now known as the \"other minds reply\". See also Can a machine have a mind? in the philosophy of AI.)[13]",

Thus the long release intervals, and the inevitable disappointment when long-awaited releases are not perfect.\nIn the bazaar view, on the other hand, you assume that bugs are generally shallow phenomena—or, at least, that they turn **shallow pretty quickly when exposed to a thousand eager co-developers pounding on every single new release**.

Further, typical implementations of data structures in our programming languages provide no ways to represent or reconcile concurrent changes at all. Together, this means that concurrent actors moving state around or representing operations using these data structures and representations have no generally applicable way of resolving conflicting concurrent changes.

What I appreciate most about this paper is that he talks about the difficulties of communication among concurrent, distributed actors as a physics problem. Contemplating the challenges of a distributed system reveals this as more than a convenient analogy, and closer to actual fact: the essential qualities of the distance between separate actors and the progression of time that paces their communications define what is and is not possible",

"On the other hand, there are certain approaches to distributed systems that, in attempting to address their unique challenges, propose a total and holistic shift in programming practice. Bloom — the programming language that has been used to research and prototype the CALM theorem — is an effort in this direction. The vast majority of data structures that you manipulate as a matter of course in Bloom are lattices or other monotonic constructs. The tradeoff here is that while Bloom can statically identify which parts of your program are non-monotonic — in join semilattice terms, where your program state descends in the partial order, and thus is exposed to e.g. common network failure modes — Bloom is the only place where you can reap the benefits of that analysis.",

"This community is about figuring out how we (as in us, as creators) can design better ways of enabling people to produce computational artifacts (i.e. with some degree of interactivity or responsiveness). I think our visions need to **start from fundamentals, rather than incremental improvements (e.g. IDEs).** I think our community follows this spirit.",

In theory, this information would allow Semantic Web browsers to answer queries across a large collection of webpages.

By 2008, JSON had begun its meteoric rise to popularity. Whereas XML came packaged with a bunch of associated technologies of indeterminate purpose (XLST, XPath, XQuery, XLink), JSON was just JSON. It was less verbose and more readable. Manu Sporny, an entrepreneur and member of the W3C, had already started using JSON at his company and wanted to find an easy way for RDFa and JSON to work together.11 The result would be [[JSON-LD]], which in essence was **RDF reimagined for a world that had chosen JSON over XML**. Sporny, together with his CTO, Dave Longley, issued a draft specification of JSON-LD in 2010. For the next few years, JSON-LD and an updated RDF specification would be the primary focus of Semantic Web work at the W3C. JSON-LD could be used on its own or it could be embedded within a <script> tag on an HTML page, making it an alternative to both RDF and RDFa.",

"Work on JSON-LD coincided with the development of schema.org, a centralized collection of simple schemas for describing things that might exist on the web. [[schema.org]] was started by Google, Bing, and Yahoo with the express purpose of delivering better search results by agreeing to a common set of vocabularies. schema.org vocabularies, together with JSON-LD, are now used to drive features like Google’s Knowledge Graph. The approach was a more practical and less abstract one, where immediate applications in search results were the focus. The schema.org team are careful to state on their website that they **are not attempting to create a “universal ontology**.”12",

That said, many of the technologies and ideas that were developed amid the push to create the Semantic Web have been repurposed and live on in various applications.",

"Another modern application of Semantic Web technologies, perhaps the most popular and successful in recent years outside of Google, is Facebook’s [[OpenGraph]] protocol. The OpenGraph protocol defines a schema that web developers can use (via RDFa) to determine how a web page is displayed when shared in a social media application. For example, a web developer working at the New York Times might use OpenGraph to specify the title and thumbnail that should appear when a New York Times article is shared in Facebook. In one sense, this is an application of Semantic Web technologies true to the Semantic Web’s origins in research on metadata. Tagging a webpage with extra information about who wrote it and what it is about is exactly the kind of metadata authoring the Semantic Web was going to depend on. But in another sense, **OpenGraph is an application of Semantic Web technologies to further a purpose somewhat at odds with the philosophy of the web**. The metadata isn’t meant to be general-purpose, after all. People tag their webpages using OpenGraph because they want links to their content to unfurl properly in Facebook. And the more information Facebook knows about your website, the closer **Facebook gets to simply reproducing your entire website within Facebook**, portending a future where the open web is a mythical land beyond Facebook’s towering blue walls.",

This enormously greater variety is an index of the great structural complexity a semilattice can have when compared with the structural simplicity of a tree.** It is this lack of structural complexity, characteristic of trees, which is crippling our conceptions of the city.**",

"Either grouping taken by itself is a tree structure. The two together are a semilattice. Now let us try and visualize these groupings in the mind's eye. I think you will find that you cannot visualize all four sets simultaneously—because they overlap. You can visualize one pair of sets and then the other, and you can alternate between the two pairs extremely fast, so that you may deceive yourself into thinking you can visualize them all together. But in truth, you cannot conceive all four sets at once in a single mental act. You cannot bring the semilattice structure into a visualizable form for a single mental act. In a single mental act you can only visualize a tree.",

"It is known today that grouping and categorization are among the most primitive psychological processes. Modern psychology treats thought as a process of fitting new situations into existing slots and pigeonholes in the mind. Just as you cannot put a physical thing into more than one physical pigeonhole at once, so, by analogy, the processes of thought prevent you from putting a mental construct into more than one mental category at once. Study of the origin of these processes suggests that they stem essentially from the organism's need to reduce the complexity of its environment by establishing barriers between the different events that it encounters. #[[Psychology]]",

The fascination of this painting lies in the fact that, although constructed of rather few simple triangular elements, these elements unite in many different ways to form the large units of the painting—in such a way indeed that, if we make a complete inventory of the perceived units in the painting, we find that each triangle enters into four or five completely different kinds of unit, none contained in the others, yet all overlapping in that triangle.",

But don’t think this means an MBA is required – actually not one of the impressive product managers I described has an MBA – or that you need to have all these skills yourself; you must simply have a broad understanding of how a product can affect a business, and work with people from your team and across your company to cover everything that’s important.",

After teaching a software engineering laboratory more than 20 times, I came to insist that student **teams as small as four people choose a manager and a separate architect**. Defining distinct roles in such small teams may be a little extreme, but I have observed it to work well and to contribute to design success even for small teams.”",

Thus, the spirit and tradition of ITS was preserved as an important part of the newer, Unix and VAX-centered hacker culture.

The ability to add or remove people's commit passwords for one project on a particular hosting site affects only that copy of the project on that site.
