    1. Expert Smart Contract Development Guide for 2019

      What is a smart contract?

      For those of you who don’t know, a smart contract is a self-executing contract that digitally facilitates, verifies and enforces the agreed terms between two or more parties.

    1. Eliminating the fraction of demand that occurs in these spikes eliminates the cost of adding reserve generators, cuts wear and tear and extends the life of equipment, and allows users to cut their energy bills by telling low priority devices to use energy only when it is cheapest.

      Official basic solidity explanation. Notice the warnings about new versions breaking old coding methods. This is very common in solidity as it is still viewed as an in development language. Solidity is expected to remain a blockchain smart contract programming standard for quite sometime while other competing languages such as Rust, Java, C++, etc are expected to gain more ground particularly due to the introduction of the WASM low level language and the toolkit that supports it which is well established and well integrated. Here's a link to some more WASM goodness. https://hackernoon.com/the-three-eggs-in-a-distributed-basket-wasm-blockchain-and-reputation-296892cdd77c

    1. EthereumEthereum is a distributed computer; each node in the network executes some bytecode (hint: Smart Contracts), and then stores the resulting state in a blockchain. Due to the properties of the blockchain representing application state, this results in “applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third party interference”.

      This is a decent little explanation for how smart contracts execute on blockchains. Author missed in "Due to the properties of the blockchain" to say that all nodes must also come to consensus about how the code was executed and therefore "applications that run exactly...". We will later discuss deterministic code execution in relation to this

    2. Distributed App (dApp)

      A distributed application (Dapp) in this context is refers to an ordinary real world application that runs on an arbitrary platform (desktop, web, mobile) and that utilizes a smart contract to use blockchain technology

    1. A field study at Google[4] covering over 100,000 consumer-grade drives from December 2005 to August 2006 found correlations between certain S.M.A.R.T. information and annualized failure rates: In the 60 days following the first uncorrectable error on a drive (S.M.A.R.T. attribute 0xC6 or 198) detected as a result of an offline scan, the drive was, on average, 39 times more likely to fail than a similar drive for which no such error occurred. First errors in reallocations, offline reallocations (S.M.A.R.T. attributes 0xC4 and 0x05 or 196 and 5) and probational counts (S.M.A.R.T. attribute 0xC5 or 197) were also strongly correlated to higher probabilities of failure. Conversely, little correlation was found for increased temperature and no correlation for usage level. However, the research showed that a large proportion (56%) of the failed drives failed without recording any count in the "four strong S.M.A.R.T. warnings" identified as scan errors, reallocation count, offline reallocation and probational count. Further, 36% of failed drives did so without recording any S.M.A.R.T. error at all, except the temperature, meaning that S.M.A.R.T. data alone was of limited usefulness in anticipating failures.[5]

    1. As retailers buckle down and prepare for potentially challenging times ahead, supply chain improvements can be a significant growth driver. But rather than just investing in trends like automation smart packaging in reaction to competitors, retailers should think about accumulating long-term competitive advantages through wider supply chain strategies.

    1. This website, Campus Technology, is an excellent source for integrating technology and teaching. The annotated section is on learning spaces designed to maximize student and teacher time. This site includes articles, tutorials, research, case studies, and more.


    1. By framing "genius" as something intrinsic rather than situational, we deny even the potential for achievement to a huge fraction of the population. As paleontologist Stephen Jay Gould wrote The Panda's Thumb, where he wrote, "I am, somehow, less interested in the weight and convolutions of Einstein’s brain than in the near certainty that people of equal talent have lived and died in cotton fields and sweatshops."
    2. The problem is far worse when used to generalize about groups, such as gender and especially race. When combined with the cultural belief that only the "brainy" are worthy of science training, it becomes a self-reinforcing cycle: only certain white men are inherently "smart enough", as decided primarily by other white men. You'll hear (and I'll bet cash money that someone will argue in the comments) that African-American underrepresentation in science is because they're not "smart" or "motivated" enough, not that black-majority school districts are often underfunded, lacking teachers, supplies, and other necessities for STEM prep — not to mention daily challenges to their authority and intelligence for those who do earn STEM degrees.

    1. It suggests a belief that intelligence is the output of a mechanical process, a series of discrete steps that can be isolated, measured, and optimized.

      I agree with this because I do no think your intelligence correlates to the information you can find on Google. Your intelligence is what you know without the help of an outside source.

    1. The development of new solutions requires systematic and targeted experiments on the right scale - and here the city itself is the best frame. Therefore, our laboratories are created for development, testing and demonstration. This creates important knowledge about which solutions can be scaled to larger areas of the city and benefit all of Copenhagen. In addition, the city laboratories provide an important knowledge base for investments in new technology.

    1. Not enough for detailed planning, but enough to bias random actions away from an informational zero mean.

      Can someone explain this to me? Has to do with variance. Not assume that variance is zero? If variance is zero, then any choice is good as any other since they all result in the same 'answer'.

    1. s. To think that cities can reclaim such sensors seems ridiculous, which makes these firms even less susceptible to dialogue with city leaders

      Hier rächt sich aber auch die konzeptionelle Leerstelle Smart Home/Smart Self beim Versuch des Policy Makings für die "Smart City von unten". Die Technologien dieser Felder werden dann nämlich hinterrücks zu Sachzwängen und "Naturphänomenen".

      Grob formuliert: Wer nicht über die Smartphone-freie Stadt zumindest nachdenkt, der sollte über die Smart City schweigen.

    2. producing

      Die Daten werden im Alltag von Menschen und Maschinen produziert. Was hier gemeint ist, ist "accumulating": Wer in der Lage ist, die meisten Daten zu sammeln, zusammenzukaufen oder eben produzieren zu lassen, der ...

      In dieser anderen Sichtweise fällt dann nämlich die Möglichkeit des "Datenstreiks" auf: Wenn wir uns der Arbeit des Daten-Produzierens entziehen, dann haben die Datenkonzerne auch kein Futter mehr für ihre AI. Wir müssen zwar - so ist die Realität beschaffen -, um zu überleben, bestimmte Datenspuren legen, aber wir können uns darin organisieren, streiken und unsere Position so verbessern.

      Nicht anders hat es die alte Arbeiterbewegung mit ihrer Arbeit auch gemacht, obwohl sie "von ihr" auch leben musste. Datenproduktion ist Arbeit. Die Smart City ist die Fabrik der Datenindustrie, das Smarte Home die Produktionseinheit und das Smarte Self ist der/die Arbeiter*in. Hat nur noch kaum wer realisiert...

    3. In addition, the proliferation of secondary data about tenants permits to screen them more effectively, thus reducing the risks of delayed payments and any other costs associated with problematic tena

      In dieser Andeutung verweist der Text auf seine eigene Leerstelle zum Thema "Smart Self".

    6.  heating,  ventilation,  lighting  and  air  conditioni

      Das ist Smart Home! Die konzeptionelle Abtrennung und Privatisierung des Komplexes Smart Home ist eine Strategie der Herrschenden. Die Smart City ist ohne die Techniken des Smart Home (und Smart Self) nicht realisierbar. Den Konzernen ist das klar, ihre Produktpaletten kennen die Trennung nicht, ihre Technologien von Smart City, Smart Home und Smart Self lassen sie nahtlos ineinander greifen. Das ahnt auch der Text, deshalb benennt er die Technikbereiche hier im Kasten. Er versäumt aber die Kritik am Dreiklang Smart Home-Smart City-Smart Self.

    7. geopolitics of the smart city agenda

      Die Geopolitik der Smart City hat der Text auf dem Schirm. Was fehlt ist eine Abgrenzung oder besser noch: eine Problematisierung der Zusammenhänge mit Smart Home und Smart Self. Dass diese beiden Konzepte gar keine Rolle spielen, fällt dem Text noch auf die Füße, dazu weiter hinten mehr (z.b. S. 25).
