    1. Meanwhile, we remain trapped in two countries. Each one is split by two narratives—Smart and Just on one side, Free and Real on the other. Neither separation nor conquest is a tenable future. The tensions within each country will persist even as the cold civil war between them rages on.

    1. With the web API, you can only pull data at rest, meaning you'll need to sync your Sense to the Fitbit app before you can fetch the data. The endpoint you'd use to fetch this data is the Intraday Heart Rate Time Series endpoints. If you'd like to test this endpoint, you can do it with the Fitbit API Explorer.    If you're looking to fetch real-time/raw data with 1sec detail level, you'll want to use the Device API and SDK to create a clock face. You can get further assistance from other developers and our moderators in the SDK forum here.

    1. Wear OS is a smartwatch operating system created and maintained by Google. It was announced on March 18, 2014 as Android Wear, only to be rebranded as Wear OS on March 15, 2018. Wear OS is an Android-based operating system that receives semi-regular feature and security updates, just like the version of Android that powers billions of smartphones around the world.

    1. The data is queried directly from your Fitbit account and inserted into Google Fit. To do this, you must first log in with your Fitbit account and give FitToFit access to the data that you want to transfer. You will then be asked to connect to your Google account, into which the data from Fitbit should be inserted.

      Cannot directly interface with fitbit with Google fit, can only export processed data from fit bit and send to google fit...

    1. The Google Fit APIs for Android are part of Google Play services. The Google Fit APIs are supported on Android 4.1 (API level 16) and higher. Using these APIs, your app can do the following: Read near-real-time and historic data, including data from Bluetooth Low Energy (BLE) devices. Record activities. Associate data with a session. Set fitness goals.

      Google Fit API for Android allows raw data access!!!

    1. Sensors API

      Fit bit's sensor API... only preprocessed data and not raw. Fit bit does not use Android API for sensor access..

    1. As mentioned before, sensors such as the Empatica provide some raw data (E.g. raw PPG), although the cost is very high (around $ 1700 US). Moreover, smartwatches such as the Moto360 or the LG G Watch R can be programmed to provide HR data. However, you should consider that this is preprocessed data (from manufacturers) and we just have access to the processed data (not the raw PPG). Therefore, if you wanted to make things such as Heart Rate Variability analysis, this approach is not highly accurate. I have been working with the Polar Chest Band (H7) and it seems that we can access both HR and RR-interval data with an Android app (currently working in an APK to extend it in our PhysioVR framework).

Use this API to do the following: List data sources that are available on the device and on companion devices. Register listeners to receive raw sensor data. Unregister listeners so that they no longer receive raw sensor data.

      Google fit allows access to raw sensor data

    1. Depends on vendor, it would be possible to access the raw ppg signal of wear os sensor, should you have access to sensor hardware driver. Some researchers did analysed PPG raw signal from Huawei watch 2 and here is the paper.

    1. ransformative economic model for artists via NFT contracts. This is perhaps my favorite advantage of all — the ability for artists to automatically gain a percentage of every sale of their work in the secondary market in perpetuity. I mean, can you imagine!? Artists can evolve from getting ~50% of the initial acquisition price of their work in a gallery to a new world where they get 80%+ (depending on marketplace they use) of the proceeds on their initial sale plus 10–15% of every secondary sale forever! Imagine the families of artists anywhere receiving residuals for generations much like the world's greatest bands as their work continues to grow in value and trade hands. F----ng transformative.

      Agrees that it is the smart contract residual % payment royalty aspect that is the most powerful aspect of NFTs

      heard from some others though that you can do off chain transactions of the NFT to get around this ?

    1. A smart contract is a piece of special purpose code executing a complex set of instructions on the blockchain. It's a means of codifying the terms of a deal in software. Now, this could be a business deal between producers and consumers, or it could be a social pact between a government and its citizens. What's important here is this, smart contracts ensure contractual compliance. They hold parties accountable. The blockchain provides a high degree of certainty as to the outcome of these agreements. Oh and smart contracts self-executing without the need for intermediaries like banks are governments and frankly, we've never had that kind of assurance before.

    1. Instead of having a task like “write an outline of the first chapter,” you have a task like “find notes which seem relevant.” Each step feels doable. This is an executable strategy (see Executable strategy).

      Whereas Dr. Sönke Ahrens in How to Make Smart Notes seemed to be saying that the writing of a permanent note (~evergreen note) is a unit of knowledge work with predictable effort & time investment (as well as searching for relevant notes), Andy emphasizes only the note searching activity in this context.

    1. Ericsson claims (2016, p. 98) that there is no deliberate practice possible for knowledge work because there are no objective criteria (so, poor feedback), because the skills aren’t clearly defined, and because techniques for focused skill improvement in these domains aren’t known.

      According to Ericsson deliberate practice for knowledge work is not possible because the criteria are not objective (you don't know if you're doing well).

      This collides with Dr. Sönke Ahrens' contention that note taking, specifically elaboration, instantiates two feedback loop. One feedback loop in that you can see whether you're capturing the essence of what you're trying to make a note on and a second feedback loop in that you can see whether your note is not only an accurate description of the original idea, but also a complete one.

      Put differently, note taking instantiates two feedback loops. One for precision and one for recall.

    1. This is a perfect environment for gold to take center stage. Fanatical debasement of moneyby all of the world’s central banks, super-low interest rates and gold mine operation and extractionissues(to a large extent related to the pandemic)should create a fertile ground for this most basic of all money and storesof value to reach its fair value, which we believe is literally multiples ofits current price. In recent months,goldhas gone up in price to some degree, but we think that it is one of the most undervalued investable assetsexisting today. There is nothing else that has its historical and fundamental characteristics,and we think that itis only beginning its inexorable, but 11impossibletotimeand placeboundaries around, uptrend.The fact that it is so under-ownedby institutional investors is astonishing to us in light of the obsessively inflationary policies being pursued by central banks around the world

    2. The potential opportunity setis primarily in credit. Of course,equities thathave fallen 20%, 30%or50% in a very short time can provide substantial upside, but in periodslike this one, we prefer the additional downside protection of carefullyresearched debt. The Holy Grail(which presented itself in size in 2008)is to have credit positions in which we have so much confidence andwhich have so muchconvexity (asymmetric return profiles; much more upside than downside) that hedges are either not needed or can be relatively small.A great example wasauto finance unsecured debt in 2008, which at the bottom was trading at levels thatanticipated many more defaults than at any time in history.Such credit positions fell in priceto many points below our “scientificallyderived”bedrock-bottom prices, but we had a lot of confidence in the ultimate repayment of the debt

    3. While it is near-universally believed that the global, particularly the American, economy was humming on all cylinders before being slugged flat by the virus, we believed that the pre-virusfinancialassets landscape was toward the high end of the riskiness scale. The record-high global leverage, the record-low government-manipulated interest rates, the $20 trillion of purchased bonds and stocks still on the books of the major central banks from the non-stop emergency policies pursued for 10 years after the emergency was over, presented a highly risky and unsound picture. It is on thatterrainthat the virus landed.

    1. "The replication crisis, if nothing else, has shown that productivity is not intrinsically valuable. Much of what psychology has produced has been shown, empirically, to be a waste of time, effort, and money. As Gibson put it: our gains are puny, our science ill-founded. As a subject, it is hard to see what it has to lose from a period of theoretical confrontation. The ultimate response to the replication crisis will determine whether this bout is postponed or not."

      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. 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.
