What is cryptocurrency?

A cryptocurrency (or crypto currency) is a digital asset

Cryptocurrency is designed to work as a medium of exchange using cryptography to secure the transactions and to control the creation of additional units of the currency

Cryptocurrencies are classified as a subset of digital currencies and are also classified as a subset of alternative currencies and virtual currencies.

Bitcoin became the first decentralized cryptocurrency in 2009. Since then, numerous cryptocurrencies have been created. These are frequently called altcoins, as a blend of bitcoin alternative. Bitcoin and its derivatives use decentralized control as opposed to centralized electronic money/centralized banking systems. The decentralized control is related to the use of bitcoins blockchain transaction database in the role of a distributed ledger.

What is Blockchain?

A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography

Each block contains typically a hash pointer as a link to a previous block, a timestamp and transaction data. By design, blockchains are inherently resistant to modification of the data. Functionally, a blockchain can serve as an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way. For use as a distributed ledger a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks and a collusion of the network majority.

Blockchains are secure by design and are an example of a distributed computing system with high Byzantine fault tolerance. Decentralized consensus has therefore been achieved with a blockchain. This makes blockchains potentially suitable for the recording of events, medical records, and other records management activities, such as identity management, transaction processing, documenting provenance, or food traceability.

The first distributed blockchain was conceptualised by Satoshi Nakamoto in 2008 and implemented the following year as a core component of the digital currency bitcoin, where it serves as the public ledger for all transactions. The invention of the blockchain for bitcoin made it the first digital currency to solve the double spending problem, without the use of a trusted authority or central server. The bitcoin design has been the inspiration for other applications.

What is Kodi?

Kodi (formerly XBMC) is a free and open-source media player software application developed by the XBMC Foundation, a non-profit technology consortium

Kodi is available for multiple operating systems and hardware platforms, with a software 10-foot user interface for use with televisions and remote controls. It allows users to play and view most streaming media, such as videos, music, podcasts, and videos from the internet, as well as all common digital media files from local and network storage media.

It is a multi-platform home-theater PC (HTPC) application. Kodi is highly customizable: a variety of skins can change its appearance, and various plug-ins allow users to access streaming media content via online services such as Amazon Prime Instant Video, Crackle, Pandora Internet Radio, Rhapsody, Spotify, and YouTube. The later versions also have a personal video-recorder (PVR) graphical front end for receiving live television with electronic program guide (EPG) and high-definition digital video recorder (DVR) support.

The software was created as an independently developed homebrew media player application named Xbox Media Center (abbreviated as XBMC) for the first-generation Xbox game console, and was later made available under the name XBMC as a native application for Android, Linux, BSD, macOS, iOS/tvOS, and Microsoft Windows-based operating systems.

What is Articoolo?

Articoolo is a bot writing articles

Articoolo’s content creator works like the human brain when asked to write an article. First, it will analyze and understand the context of your topic. For instance if you wanted it to write an article about “The appliance variety of Apple”, the algorithm will understand first that “Apple” in this context is a name of a corporation, not a fruit. After understanding the context of your topic, it will find the best base resources, and extract sentiment and important keywords. The software will then find related content based on sentiment and main keywords, reconstructing everything to one coherent piece of text. Then it will rewrite the text using NLP engine for multi-level semantic identification and verify its readability.

At the end of the process, which won’t take more than a minute, you will have a completely unique, coherent starting point for your article.

Want to know more, or try the service out, please check Articoolo.

What is Snapchat?

Snapchat is an image messaging and multimedia mobile application

Snapchat is created by Evan Spiegel, Bobby Murphy, and Reggie Brown, former students at Stanford University, and developed by Snap Inc, originally Snapchat Inc. One of the principal concepts of Snapchat is that pictures and messages are only available for a short time before they become inaccessible. The prototype for Snapchat was started by Brown and Spiegel as a project for one of Spiegels classes at Stanford, where Spiegel was a product design major. Beginning as Picaboo, the idea was to create a selfie app (application) which allowed users to share images that were explicitly short-lived and self-deleting. The temporary nature of the pictures would therefore encourage frivolity and emphasize a more natural flow of interaction. When, in April 2011, Spiegel floated the product idea in front of his class as a final project, the classmates focused on the impermanent aspect of the potential product, and balked at the thought of temporary photos. Murphy was eventually brought into the project to write the source code for the application, and Picaboo first launched as an iOS-only app in July 2011 from Evan Spiegels living room (who was still staying at home with his father when not away at school). The application was relaunched two months later under the name Snapchat.

Snapchat evolved into a mix of private messaging and public content, including brand networks, publications, and live events such as sports and music. Nevertheless, according to survey studies conducted in March 2016, the personal oriented messaging was still being accessed by users more than the publicly offered content that was being presented. 71% of users surveyed said that they preferred the app for its chat, messaging, and imaging services, versus 5% who almost exclusively chose the various events, published features, and media content on a daily basis. 24% responded that they accessed all features equally. However, about three quarters of those surveyed were also familiar with the events, media brands, and celebrity content, having a favorable opinion of those areas.

What does MOAB mean?

MOAB means Massive Ordnance Air Blast

The GBU-43/B Massive Ordnance Air Blast, commonly known as the Mother of All Bombs is a large-yield conventional (non-nuclear) bomb, developed for the United States military by Albert L. Weimorts, Jr. of the Air Force Research Laboratory. At the time of development, it was touted as the most powerful non-nuclear weapon ever designed. The bomb was designed to be delivered by a C-130 Hercules, primarily the MC-130E Combat Talon I or MC-130H Combat Talon II variants. The MOAB is the largest conventional bomb ever used in combat after being deployed in Afghanistan on 13 April 2017.

In 2007, Russia tested a thermobaric weapon nicknamed the Father of All Bombs; the weapon is claimed to be four times as powerful as the MOAB.

What is Detection limit?

In analytical chemistry, the detection limit, lower limit of detection, or LOD (limit of detection), is the lowest quantity of a substance that can be distinguished from the absence of that substance (a blank value) within a stated confidence limit (generally 1%)

The detection limit is estimated from the mean of the blank, the standard deviation of the blank and some confidence factor. Another consideration that affects the detection limit is the accuracy of the model used to predict concentration from the raw analytical signal.

There are a number of different detection limits that are commonly used. These include the instrument detection limit (IDL), the method detection limit (MDL), the practical quantification limit (PQL), and the limit of quantification (LOQ). Even when the same terminology is used, there can be differences in the LOD according to nuances of what definition is used and what type of noise contributes to the measurement and calibration.

The figure below illustrates the relationship between the blank, the limit of detection (LOD), and the limit of quantification (LOQ) by showing the probability density function for normally distributed measurements at the blank, at the LOD defined as 3 * standard deviation of the blank, and at the LOQ defined as 10 * standard deviation of the blank. For a signal at the LOD, the alpha error (probability of false positive) is small (1%). However, the beta error (probability of a false negative) is 50% for a sample that has a concentration at the LOD (red line). This means a sample could contain an impurity at the LOD, but there is a 50% chance that a measurement would give a result less than the LOD. At the LOQ (blue line), there is minimal chance of a false negative.
