Stop Worrying About How Much Energy Bitcoin Uses - Government Technology
Electricity is 90 percent of the cost to mine bitcoin. As such, bitcoin mining uses an exorbitant amount of power: somewhere between an estimated 30 terrawatt hours alone in 2017 alone. That’s as much electricity as it takes to power the entire nation of Ireland in one year.

Indeed, this is a lot, but not exorbitant. Banking consumes an estimated 100 terrawatts of power annually. If bitcoin technology were to mature by more than 100 times its current market size, it would still equal only 2 percent of all energy consumption.

Google Suppresses Memo Revealing Plans to Closely Track Search Users in China
The Dragonfly memo reveals that a prototype of the censored search engine was being developed as an app for both Android and iOS devices, and would force users to sign in so they could use the service. The memo confirms, as The Intercept first reported last week, that users’ searches would be associated with their personal phone number. The memo adds that Chinese users’ movements would also be stored, along with the IP address of their device and links they clicked on. It accuses developers working on the project of creating “spying tools” for the Chinese government to monitor its citizens.

People’s search histories, location information, and other private data would be sent out of China to a database in Taiwan, the memo states. But the data would also be provided to employees of a Chinese company who would be granted “unilateral access” to the system

Today we do things slightly different, mostly due to mobile devices. If I were to imagine MilkCaps being played today I would think it were being played on mobile devices and computers.

Unenumerated: How to succeed or fail on a frontier
In the early 15th century, two nations at opposite ends of the world -- one vast and the other tiny, one an ancient and advanced civilization and the other recently emerged from a barbaric Dark Ages, one fielding large fleets with large ships, the other fielding small fleets with small ships -- both set out on the sea. Told that one of these nations was destined to travel around Africa and conquer the main sea trade routes of the world by the early part of the 16th century, any rational observer would conclude that this prophecy must refer to the vast and ancient civilization with its giant fleets. That observer would have been wrong. But why?

Standardizing value: Why token standards are critical for non-fungible tokens
What do railroads, credit cards, and CryptoKitties have in common? The answer is that they were all enabled by industry standards. As a definition, industry standards are established norms or requirements followed by the members of an industry. Many industries have embraced standards as a way to unlock value from emerging technologies. I believe that cryptoassets, and specifically non-fungible tokens (NFTs), will follow a similar path.

How will NFTs change games? – Decentraland
Crypto offers two new building blocks to the game developer. First, smart contracts allow developers to create publicly verifiable rules, users can connect with one another globally without being hindered by national borders, and money for transactions is built in to the protocol.
Second, non-fungible tokens (NFTs) provide provably scarce, programmable, and censorship resistant digital goods. These building blocks will enable developers to augment existing game formats as well as create new game formats.
Today’s crypto games are highly focused on experimenting with NFTs. In this post, I want to ask the following question: what impact will NFTs (or crypto-collectibles) have on games?

The point of this writing is to explore the potential outcomes of using an ERC20 Bonded Curve Token (as per Simon de la Rouviere) or Liquid/Smart Token (as per Bancor) as the owner address of an ERC721 Non Fungible Token (NFT). Instead of a specific individual owning a specific NFT, they could hold a quantity of fungible tokens that represent in some way the original NFT. I suggest this could have interesting applications in curation markets for Art, Intellectual Property and digital paywalls.

Non Fungible Tokens – Hacker Noon
Crypto tokens, like their physical counterparts can have many properties. Fungibility is a core characteristic of currencies. When a token is fungible it usually means 2 things:
Only the quantity matters. My fungible tokens and your tangible tokens are indistinguishable and, if we have the same amount, we can swap them.
Any amount of it can be “merged” into a larger amount of it making it undistinguishable from the rest.
[..] Anything that does not have these 2 properties is, by definition, non fungible. Even though at this point the blockchain ecosystem has been focusing on creating fungible assets (mostly through currencies), there is, in fact, a much wider range of possibilities once we let go of fungibility for assets.

Dead Man Switch – Hacker Noon
In the crypto context the idea is to use a reverse multi-signature transaction which transfers all your funds to your beneficiary’s account, but only if it is not approved until a certain block height. The idea is that as long as you are alive, you will always remember to approve this transaction before the deadline to prevent it from executing. Next, you need to submit a new recovery transaction with a later deadline, and so on. This way when you die, after the approval block height is reached, your funds will be automatically transferred to your beneficiaries.

The Strange Birth and Long Life of Unix - IEEE Spectrum
And with that little programming exercise, a second door cracked ajar. It was to swing wide open during the summer of 1969 when Thompson’s wife, Bonnie, spent a month visiting his parents to show off their newborn son. Thompson took advantage of his temporary bachelor existence to write a good chunk of what would become the Unix operating system for the discarded PDP‑7. The name Unix stems from a joke one of Thompson’s colleagues made: Because the new operating system supported only one user (Thompson), he saw it as an emasculated version of Multics and dubbed it “Un-multiplexed Information and Computing Service,” or Unics. The name later morphed into Unix.
