Villages as homogeneous legal community units cannot be equated with cities in the process ofadopting information technology (Pranita and Kesa, 2021; Ehnberg et al., 2021; Hadian & Susanto,2022; Rachmawati, 2018). The smart city concept cannot be applied in villages that carry the smartvillage terminology because of the homogeneity of the people as well as local characteristics andculture.

So far, smart city systems are being set up to appropriate and commercialize individual and community data. So far, communities are not waking up to the realization that a capacity they need is being stolen from them before they have it.”

ProPublica recently reported that breathing machines purchased by people with sleep apnea are secretly sending usage data to health insurers, where the information can be used to justify reduced insurance payments.

This economic logic has now spread beyond the tech companies to new surveillance–based ecosystems in virtually every economic sector, from insurance to automobiles to health, education, finance, to every product described as “smart” and every service described as “personalized.”

I mean people suggested that you could replace  legal contracts with small contracts which are   programs that are built on the blockchain and  that's usually accompanied with the phrase coder's   law this is a smart contract and this is a legal  contract these two things aren't the same right   you can't have law be enacted by computer code  because law inherently requires third parties   to assess evidence intentions and a bunch of  other variables that you just can't Outsource

An oracle is a conventional program which runs off the blockchain and which periodically publishes information about the world onto the blockchain. The problem is trust. Using an oracle turns your clever blockchain program into a fairly pointless appendage to the much more important (and subjective) conventional program: the one which is interpreting the world and drawing conclusions.

the institutional response to smart innovation is based on an evaluative mechanism which is driven by metrics of efficiency and a rationale of technocratic and post-political governance

While claiming to increase meaningful forms of direct participation, neoliberal governance works within structuring bureaucratic and ideological path dependencies and often hinges on computational forms of participation which are set already within circumscribed software environments and solution

“As neoliberal citizenship sets loose the individual to take care of itself, it also discursively binds the individual to the well-being of the whole”

std::shared_ptr can be used when you need multiple smart pointers that can co-own a resource. The resource will be deallocated when the last std::shared_ptr goes out of scope. std::weak_ptr can be used when you want a smart pointer that can see and use a shared resource, but does not participate in the ownership of that resource.

Always make a copy of an existing std::shared_ptr if you need more than one std::shared_ptr pointing to the same resource.

Second, don’t manually delete the resource out from underneath the std::unique_ptr.

Use std::make_unique() instead of creating std::unique_ptr and using new yourself.

Favor std::array, std::vector, or std::string over a smart pointer managing a fixed array, dynamic array, or C-style string.

Because std::unique_ptr is designed with move semantics in mind, copy initialization and copy assignment are disabled. If you want to transfer the contents managed by std::unique_ptr, you must use move semantics.

The Five Elements of Design Thinking

A Smart pointer is a composition class that is designed to manage dynamically allocated memory and ensure that memory gets deleted when the smart pointer object goes out of scope.

Though firmly rooted in Renaissance culture, Knight's carefully calibrated arguments also push forward to the digital present—engaging with the modern library archives where these works were rebound and remade, and showing how the custodianship of literary artifacts shapes our canons, chronologies, and contemporary interpretative practices.

One of the best things about classes is that they contain destructors that automatically get executed when an object of the class goes out of scope. So if you allocate (or acquire) memory in your constructor, you can deallocate it in your destructor, and be guaranteed that the memory will be deallocated when the class object is destroyed (regardless of whether it goes out of scope, gets explicitly deleted, etc…).

RemoteStorage requires the server to support a subset of OAuth, and that's the only kind of authentication supported. It also requires WebFinger support

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.

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.

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.

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.

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.

Sensors API

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.

The PPG data were collected with Huawei Watch 2

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.

Each Fitbit device includes a variety of hardware sensors that have been exposed through our Sensor APIs.

Unfortunately this is not available via an API at this time.

Use Samsung's SDK and it will give you the raw values (values range from 0 to ~64600 if I remember correctly).

This is a simple application I slapped together for the heart rate data that I captured here from the Apple Watch.

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.

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.

To defeat facial recognition software, “you would have to wear a mask or disguises,” Tien says. “That doesn’t really scale up for people.”

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).

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.

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

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

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.

It is on thatterrainthat the virus landed.

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”.

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]

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.
