Bitcoins are created as a reward in a competition in which users offer their computing power to verify and record bitcoin transactions into the blockchain. This activity is referred to as mining and successful miners are rewarded with transaction fees and newly created bitcoins.[14]:5–7 Besides being obtained by mining, bitcoins can be exchanged for other currencies,[21] products, and services.[22] When sending bitcoins, users can pay an optional transaction fee to the miners.[23] This may expedite the transaction being confirmed. According to a research produced by Cambridge University in 2017, there are between 2.9 million and 5.8 million unique users actively using a cryptocurrency wallet, most of them using bitcoin. The number of active users has grown significantly since 2013 (there were 0.3 to 1.3 million unique users at the time).[28] Etymology and orthography There is no uniform convention for bitcoin capitalization.

wikipedia, History of Bitcoin The price of a bitcoin reached previous all-time high of US$1124.76 on 29 November 2013, up from just US$13.36 on 5 January at the start of the year; the price subsequently dropped into the $700 range. Bitcoin is the first cryptocurrency, a form of money that uses cryptography to control its creation and management, rather than relying on central authorities.[1] However, not all of the technologies and concepts that make up Bitcoin are new; the presumed pseudonym Satoshi Nakamoto (the creator of Bitcoin, see below) integrated many existing ideas from the cypherpunk community when creating Bitcoin. Pre-history[edit] Independently and at around the same time Wei Dai proposed b-money [3] and Nick Szabo proposed bit-gold.[4] Subsequently Hal Finney implemented and deployed RPOW a reusable form of hashcash based on IBM secure TPM hardware and remote attestation (centralized but with no issuer inflation risk). Creation[edit] Growth[edit]

Anonymous Animals in Google Drive Google found a funny way to show the anonymous persons who open a document in Google Drive. Instead of only using different colors for each person, Google Drive associates each person with an animal, so you'll see things like "anonymous anteater", "anonymous moose", "anonymous chupacabra", "anonymous axolotl", "anonymous kraken", "anonymous gopher", "anonymous jackalope". Google also uses special icons for each animal. For the moment, this only works for PDF files, photos, videos and other files that can't be edited using Google's apps. The Bitcoin bubble 11 April 2013Last updated at 08:01 ET Yesterday afternoon I looked at my mobile phone and found that I had $121 (£79) in it. A couple of hours later though, I only had $79 (£51). But by this morning my phone told me I had $93 (£60) to spend. Actually, what I had was 0.53 in Bitcoin, the virtual currency whose wild gyrations over the last 24 hours have raised questions about its long-term viability.

wikipedia, Satoshi Nakamoto Satoshi Nakamoto (中本 哲史[1], Nakamoto Satoshi?) is a person or group of persons who created the Bitcoin protocol and reference software, Bitcoin Core. In 2008, Nakamoto published a paper[2][3] on The Cryptography Mailing list at[4] describing the Bitcoin digital currency. In 2009, he released the first Bitcoin software that launched the network and the first units of the Bitcoin currency, called bitcoins.[5][6] Nakamoto is said to have continued to contribute to his Bitcoin software release with other developers until contact with his team and the community gradually began to fade in mid-2010. Near this time, he handed over control of the source code repository and alert key functions of the software to Gavin Andresen.[7] Also around this same time, he handed over control of the domain and several other domains to various prominent members of the Bitcoin community.

Petrichor Petrichor (/ˈpɛtrɨkɔər/) is the earthy scent produced when rain falls on dry soil. The word is constructed from Greek, petra, meaning ‘stone’ + ichor, the fluid that flows in the veins of the gods in Greek mythology. In 2015, MIT scientists used high-speed cameras to record how the scent moves into the air.[5] The tests involved approximately 600 experiments on 28 different surfaces, including engineered materials and soil samples.[6] When a raindrop hits a porous surface, small bubbles form that float to the surface and release aerosols.[5] Such aerosols carry the scent as well as bacteria and viruses from the soil.[5] Raindrops that move at a slower rate tend to produce more aerosols; this serves as an explanation for why the petrichor is more common after light rains.[5] Some scientists believe that humans appreciate the rain scent because ancestors may have relied on rainy weather for survival.[7] References[edit] Jump up ^ Bear, I.J.; R.G.

Kyle Drake to Present “Building a Real-time geolocation game with Geoloqi using Node.JS” @ #NodePDX - Geoloqi Blog Geoloqi Developer Kyle Drake will be presenting how he and the team at Geoloqi built a real-time geolocation game with Node.js and the Geoloqi API & Services. A quick description of Kyle’s presentation: There are very powerful things you can do with Node.JS, particularly with projects needing a lot of I/O operations. At Geoloqi, we have used Node.JS and Socket.IO to build a JavaScript client that allows our developers to map real-time tracking on a browser with almost no code needed. Our first project using this is MapAttack!, a truly real-time location-based geofencing game.Hear about how we made the game, how we made it real-time, where we’re going, and where Node.JS is going to have a role in it.
