Physical primecoins
Unlike most earlier display protocols, X was specifically designed to be used over network connections rather than on an integral or attached display device. X features network transparency, which means an X program running on a computer somewhere on a network can display its user interface on an X server running on other computer on the network.
The fact that the server is applied to the software in front of the user is often surprising to users accustomed to their programs being clients to services on remote computers. Xs network protocol is based on X command primitives and this approach allows both 2D and 3D operations by an X client application which might be running on a different computer to still be fully accelerated on the X servers display.
X provides no support for audio, several projects exist to fill this niche. X uses a model, an X server communicates with various client programs. The server accepts requests for graphical output and sends back user input, a client and server can even communicate securely over the Internet by tunneling the connection over an encrypted network session.
An X client itself may emulate an X server by providing services to other clients. This is known as X nesting, open-source clients such as Xnest and Xephyr support such X nesting. Bitcoin — Bitcoin is both a cryptocurrency and an electronic payment system,3 invented by an unidentified programmer, or group of programmers, under the name of Satoshi Nakamoto.
Bitcoin was introduced on 31 October to a mailing list. The identity of Nakamoto remains unknown, though many have claimed to know it, the system is peer-to-peer, and transactions take place between users directly, without an intermediary. These transactions are verified by network nodes and recorded in a public distributed ledger called the blockchain, since the system works without a central repository or single administrator, the U.
Treasury categorizes bitcoin as a decentralized virtual currency. Bitcoin is often called the first cryptocurrency, although prior systems existed, Bitcoin is the largest of its kind in terms of total market value. Bitcoins are created as a reward in a competition in which users offer their computing power to verify and this activity is referred to as mining and successful miners are rewarded with transaction fees and newly created bitcoins.
Besides being obtained by mining, bitcoins can be exchanged for other currencies, products, when sending bitcoins, users can pay an optional transaction fee to the miners. This may expedite the transaction being confirmed, as of February , over , merchants and vendors accept bitcoin as payment.
The European Banking Authority and other sources have warned that bitcoin users are not protected by refund rights or chargebacks, the use of bitcoin by criminals has attracted the attention of financial regulators, legislative bodies, law enforcement, and media.
Criminal activities are focused on darknet markets and theft, though officials in countries such as the United States also recognize that bitcoin can provide legitimate financial services. The word bitcoin occurred in the paper that defined bitcoin published in It is a compound of the bit and coin. The white paper uses the shorter coin.
There is no convention for bitcoin capitalization. Some sources use Bitcoin, capitalized, to refer to the technology and network and bitcoin, lowercase, the Wall Street Journal, The Chronicle of Higher Education, and the Oxford English Dictionary advocate use of lowercase bitcoin in all cases, which this article follows.
The blockchain is a ledger that records bitcoin transactions. A novel solution accomplishes this without any trusted central authority, maintenance of the blockchain is performed by a network of communicating nodes running bitcoin software, transactions of the form payer X sends Y bitcoins to payee Z are broadcast to this network using readily available software applications. Source code — In computing, source code is any collection of computer instructions, possibly with comments, written using a human-readable programming language, usually as ordinary text.
The source code of a program is designed to facilitate the work of computer programmers. The source code is often transformed by an assembler or compiler into binary machine code understood by the computer, the machine code might then be stored for execution at a later time.
Alternatively, source code may be interpreted and thus immediately executed, most application software is distributed in a form that includes only executable files. If the source code were included it would be useful to a user, programmer or a system administrator, the Linux Information Project defines source code as, Source code is the version of software as it is originally written by a human in plain text.
The notion of source code may also be more broadly, to include machine code and notations in graphical languages. It is therefore so construed as to include code, very high level languages.
Often there are several steps of program translation or minification between the source code typed by a human and an executable program. The earliest programs for stored-program computers were entered in binary through the front panel switches of the computer and this first-generation programming language had no distinction between source code and machine code.
When IBM first offered software to work with its machine, the code was provided at no additional charge. At that time, the cost of developing and supporting software was included in the price of the hardware, for decades, IBM distributed source code with its software product licenses, until Most early computer magazines published source code as type-in programs, Source code can also be stored in a database or elsewhere.
The source code for a piece of software may be contained in a single file or many files. Though the practice is uncommon, a source code can be written in different programming languages. For example, a program written primarily in the C programming language, in some languages, such as Java, this can be done at run time.
The code base of a programming project is the larger collection of all the source code of all the computer programs which make up the project. It has become practice to maintain code bases in version control systems.
Moderately complex software customarily requires the compilation or assembly of several, sometimes dozens or even hundreds, in these cases, instructions for compilations, such as a Makefile, are included with the source code. Moore's law — Moores law is the observation that the number of transistors in a dense integrated circuit doubles approximately every two years. In , looking forward to the decade, he revised the forecast to doubling every two years.
The period is often quoted as 18 months because of Intel executive David House, Moores prediction proved accurate for several decades, and has been used in the semiconductor industry to guide long-term planning and to set targets for research and development. Advancements in digital electronics are strongly linked to Moores law, quality-adjusted microprocessor prices, memory capacity, sensors and even the number, digital electronics has contributed to world economic growth in the late twentieth and early twenty-first centuries.
Moores law describes a force of technological and social change, productivity. Moores law is an observation or projection and not a physical or natural law, although the rate held steady from until around , the rate was faster during the first decade. In general, it is not logically sound to extrapolate from the growth rate into the indefinite future. Intel stated in that the pace of advancement has slowed, starting at the 22 nm feature width around , Brian Krzanich, CEO of Intel, announced that our cadence today is closer to two and a half years than two.
This is scheduled to hold through the 10 nm width in late and he cited Moores revision as a precedent for the current deceleration, which results from technical challenges and is a natural part of the history of Moores law. In January , he declared that Ive heard the death of Moores law more times than anything else in my career, and Im here today to really show you and tell you that Moores Law is alive and well and flourishing.
Today hardware has to be designed in a manner to keep up with Moores law. In turn, this means that software has to be written in a multi-threaded manner to take full advantage of the hardware. In , Douglas Engelbart discussed the projected downscaling of integrated circuit size in the article Microelectronics, Engelbart presented his ideas at the International Solid-State Circuits Conference, where Moore was present in the audience.
For the thirty-fifth anniversary issue of Electronics magazine, which was published on April 19, and his response was a brief article entitled, Cramming more components onto integrated circuits.
Within his editorial, he speculated that by it would be possible to contain as many as 65, components on a single quarter-inch semiconductor, the complexity for minimum component costs has increased at a rate of roughly a factor of two per year.
Certainly over the term this rate can be expected to continue. Mersenne prime — In mathematics, a Mersenne prime is a prime number that is one less than a power of two. They are named after Marin Mersenne, a French Minim friar, the first four Mersenne primes are 3,7,31, and It is not even whether the set of Mersenne primes is finite or infinite. Though the above examples might suggest that Mp is prime for all p, this is not the case. The evidence at hand does suggest that a randomly selected Mersenne number is more likely to be prime than an arbitrary randomly selected odd integer of similar size.
Nonetheless, prime Mp appear to grow increasingly sparse as p increases, in fact, of the 2,, prime numbers p up to 37,,, Mp is prime for only 45 of them.
The lack of any simple test to determine whether a given Mersenne number is prime makes the search for Mersenne primes a difficult task, the Lucas—Lehmer primality test is an efficient primality test that greatly aids this task.
The search for the largest known prime has somewhat of a cult following, consequently, a lot of computer power has been expended searching for new Mersenne primes, much of which is now done using distributed computing.
Anarcho-capitalism — Anarcho-capitalism is a political philosophy that advocates the elimination of the state in favor of individual sovereignty, private property, and free markets. Anarcho-capitalists believe that, in the absence of statute, society would improve itself through the discipline of the free market, in an anarcho-capitalist society, law enforcement, courts, and all other security services would be operated by privately funded competitors rather than centrally through taxation.
Money, along all other goods and services, would be privately and competitively provided in an open market. Various theorists have espoused legal philosophies similar to anarcho-capitalism, a Rothbardian anarcho-capitalist society would operate under a mutually agreed-upon libertarian legal code which would be generally accepted, and which the courts would pledge themselves to follow.
This pact would recognize self-ownership and the principle, although methods of enforcement vary. Anarcho-capitalists argue for a society based on the trade of private property. However, they also recognize charity and communal arrangements as part of the same voluntary ethic, though anarcho-capitalists are known for asserting a right to private property, some propose that non-state public or community property can also exist in an anarcho-capitalist society.
For them, what is important is that it is acquired and transferred without help or hindrance from the compulsory state, anarcho-capitalists see free-market capitalism as the basis for a free and prosperous society. Many anarchists view capitalism as an authoritarian and hierarchical system. On the Nolan chart, anarcho-capitalists are located at the northernmost apex of the libertarian quadrant — since they reject state involvement in economic and personal affairs.
Many also argue that subsidized monopolies tend to be corrupt and inefficient, many anarchists also argue that private defense and court agencies would have to have a good reputation in order to stay in business.
Rothbard bases his philosophy on natural law grounds and also provides economic explanations of why he thinks anarcho-capitalism is preferable on pragmatic grounds as well. Friedman says he is not an absolutist rights theorist but is not a utilitarian, however. Peter Leeson argues that the case for anarchy derives its strength from empirical evidence, hans-Hermann Hoppe, meanwhile, uses argumentation ethics for his foundation of private property anarchism, which is closer to Rothbards natural law approach.
I define anarchist society as one where there is no possibility for coercive aggression against the person or property of any individual. In effect, this means no one else may justly invade, or aggress against. It follows then that each person justly owns whatever previously unowned resources he appropriates or mixes his labor with, from these twin axioms — self-ownership and homesteading — stem the justification for the entire system of property rights titles in a free-market society.
This system establishes the right of man to his own person, the right of donation, of bequest. Complementary currency — Many private currencies are complementary currencies issued by private businesses or organizations. Other terms include alternative currency, auxiliary currency, and microcurrency, advocates in the s, especially in Canada, promoted complementary currencies to supplement national currencies. Certain leaders of this movement were careful to use the term complementary and they used it to emphasize the importance of working in cooperation with governments and the tax system, businesses and other established organisations.
Since the s there has been an increase in the number of complementary currencies. In there was roughly , by there was over They can be useful for communities that do not have access to financial capital, aims may include, lifeboat currencies to increase financial stability.
They can be valued and exchanged in relationship to national currencies, Complementary currencies lie outside the nationally defined legal realm of legal tender and are not used as such. Rate of exchange, scope of circulation and use in combination with other currencies differs greatly between complementary currency systems, as is the case with national currency systems, some complementary currencies incorporate value scales based on time or the backing of real resources.
A time-based currency is valued by the required to perform a service in hours. Another type of monetary systems is the barter, an exchange of specific goods or services is performed without the use of any currency.
In , the most widespread auxiliary currency system — the Local Exchange Trading Systems was created and it regulates the exchange of goods and services between the members of the cooperative. The introductory fee paid by the new members is subsequently directed toward investments in a variety of commercial projects. Some complementary currencies take advantage of demurrage fees, a devaluation of the currency over time.
Some complementary currencies which are regional or global, such as the Community Exchange System, WIR and Friendly Favors, a community currency is a type of complementary currency that has the explicit aim to support and build more equal, connected and sustainable societies.
A community currency is designed to be used by a specific group, the Toronto dollar system is fully funded by Canadian dollars. Participating merchants are free to exchange the Toronto dollars for Canadian dollars, the Toronto dollar has been supported by activists, clergy and a number of political leaders, including, several mayors.
Money supply — In economics, the money supply is the total amount of monetary assets available in an economy at a specific time. There are several ways to define money, but standard measures usually include currency in circulation, Money supply data are recorded and published, usually by the government or the central bank of the country.
Public and private sector analysts have long monitored changes in money supply because of the belief that it affects the level, inflation, the exchange rate. That relation between money and prices is historically associated with the quantity theory of money, there is strong empirical evidence of a direct relation between money-supply growth and long-term price inflation, at least for rapid increases in the amount of money in the economy.
For example, a such as Zimbabwe which saw extremely rapid increases in its money supply also saw extremely rapid increases in prices. This is one reason for the reliance on monetary policy as a means of controlling inflation, the nature of this causal chain is the subject of contention.
Some heterodox economists argue that the supply is endogenous and that the sources of inflation must be found in the distributional structure of the economy. In addition, those economists seeing the central control over the money supply as feeble say that there are two weak links between the growth of the money supply and the inflation rate. First, in the aftermath of a recession, when resources are underutilized. Second, if the velocity of money changes, an increase in the supply could have either no effect.
See also European Central Bank for other approaches and a global perspective. Money is used as a medium of exchange, a unit of account and its different functions are associated with different empirical measures of the money supply.
There is no single measure of the money supply. Instead, there are measures, classified along a spectrum or continuum between narrow and broad monetary aggregates. Narrow measures include only the most liquid assets, the ones most easily used to spend, broader measures add less liquid types of assets.
This continuum corresponds to the way that different types of money are more or less controlled by monetary policy, narrow measures include those more directly affected and controlled by monetary policy, whereas broader measures are less closely related to monetary-policy actions. It is a matter of debate as to whether narrower or broader versions of the money supply have a more predictable link to nominal GDP.
The different types of money are typically classified as Ms, the Ms usually range from M0 to M3 but which Ms are actually focused on in policy formulation depends on the countrys central bank. Directed acyclic graph — In mathematics and computer science, a directed acyclic graph, is a finite directed graph with no directed cycles.
Equivalently, a DAG is a graph that has a topological ordering. DAGs can model different kinds of information. Similarly, topological orderings of DAGs can be used to order the compilation operations in a makefile, the program evaluation and review technique uses DAGs to model the milestones and activities of large human projects, and schedule these projects to use as little total time as possible.
Combinational logic blocks in electronic design, and the operations in dataflow programming languages. More abstractly, the reachability relation in a DAG forms a partial order, the corresponding concept for undirected graphs is a forest, an undirected graph without cycles.
Choosing an orientation for a forest produces a kind of directed acyclic graph called a polytree. However there are other kinds of directed acyclic graph that are not formed by orienting the edges of an undirected acyclic graph. Moreover, every undirected graph has an orientation, an assignment of a direction for its edges that makes it into a directed acyclic graph.
To emphasize that DAGs are not the thing as directed versions of undirected acyclic graphs. A graph is formed by a collection of vertices and edges, in the case of a directed graph, each edge has an orientation, from one vertex to another vertex. A directed acyclic graph is a graph that has no cycles. A vertex v of a graph is said to be reachable from another vertex u when there exists a path that starts at u.
As a special case, every vertex is considered to be reachable from itself, a graph that has a topological ordering cannot have any cycles, because the edge into the earliest vertex of a cycle would have to be oriented the wrong way.
Therefore, every graph with an ordering is acyclic. Conversely, every directed acyclic graph has a topological ordering, therefore, this property can be used as an alternative definition of the directed acyclic graphs, they are exactly the graphs that have topological orderings.
Cryptographic hash function — A cryptographic hash function is a special class of hash function that has certain properties which make it suitable for use in cryptography.
It is an algorithm that maps data of arbitrary size to a bit string of a fixed size which is designed to also be a one-way function, that is. Bruce Schneier has called one-way hash functions the workhorses of modern cryptography, the input data is often called the message, and the output is often called the message digest or simply the digest.
Most cryptographic hash functions are designed to take a string of any length as input, a cryptographic hash function must be able to withstand all known types of cryptanalytic attack. This concept is related to that of one-way function, functions that lack this property are vulnerable to preimage attacks. This property is referred to as strong collision resistance. It requires a value at least twice as long as that required for preimage-resistance. Collision resistance implies second pre-image resistance, but does not imply pre-image resistance, informally, these properties mean that a malicious adversary cannot replace or modify the input data without changing its digest.
Thus, if two strings have the same digest, one can be confident that they are identical. A function meeting these criteria may still have undesirable properties and this property can be used to break naive authentication schemes based on hash functions.
The HMAC construction works around these problems, in practice, collision resistance is insufficient for many practical uses. In particular, should behave as much as possible like a random function while still being deterministic, checksum algorithms, such as CRC32 and other cyclic redundancy checks, are designed to meet much weaker requirements, and are generally unsuitable as cryptographic hash functions.
For example, a CRC was used for message integrity in the WEP encryption standard, the meaning of the term is therefore somewhat dependent on the application, since the effort that a malicious agent may put into the task is usually proportional to his expected gain.
However, since the effort usually grows very quickly with the digest length. For messages selected from a set of messages, for example passwords or other short messages. In some theoretical analyses difficult has a specific meaning, such as not solvable in asymptotic polynomial time. Cryptographic hash functions are mathematical operations run on digital data, by comparing the computed hash to a known and expected hash value, a person can determine the datas integrity.
For example, computing the hash of a file and comparing the result to a previously published hash result can show whether the download has been modified or tampered with.
A key aspect of cryptographic hash functions is their collision resistance, SHA-2 includes significant changes from its predecessor, SHA They use different shift amounts and additive constants, but their structures are virtually identical. The United States has released the patent under a royalty-free license, in , an algorithm emerged for finding SHA-1 collisions in about 2, times fewer steps than was previously thought possible. In , an example of a SHA-1 collision was published, the security margin left by SHA-1 is weaker than intended, and its use is therefore no longer recommended for applications that depend on collision resistance, such as digital signatures.
The updated standard included the original SHA-1 algorithm, with updated technical notation consistent with that describing the workings of the SHA-2 family. In October , the standard was updated in FIPS PUB , including SHA from the change notice, the primary motivation for updating the standard was relocating security information about the hash algorithms and recommendations for their use to Special Publications and Detailed test data and example message digests were also removed from the standard, padding the final data block must still occur prior to hash output.
Namecoin — Namecoin is a cryptocurrency and the first fork of the bitcoin software. It is based on the code of bitcoin and uses the same proof-of-work algorithm and it is limited to 21 million coins. Unlike bitcoin, Namecoin can store data within its own blockchain transaction database, the original proposal for Namecoin called for Namecoin to insert data into bitcoins blockchain directly.
Anticipating scaling difficulties with approach, a shared proof-of-work system was proposed to secure new cryptocurrencies with different use cases. Namecoins flagship use case is the censorship-resistant top level domain. A peer-to-peer network similar to bitcoins handles Namecoins transactions, balances and issuance through SHA, the issuing rate forms a geometric series, and the rate halves every , blocks, roughly every four years, reaching a final total of 21 million NMC.
Namecoins are currently traded primarily for USD and other cryptocurrencies, mostly on online exchanges, to avoid the danger of chargebacks, reversible transactions, such as those with credit cards or Paypal, are not advised since Namecoin transactions are irreversible.
Payments and records in the Namecoin network are made to addresses and they are strings of 33 numbers and letters which begin with the letter N or M. Initially addresses beginning with 1 existed but this was changed to avoid confusion with Bitcoin addresses, each Namecoin record consists of a key and a value which can be up to bytes in size. Each key is actually a path, with the preceding the name of the record. The current fee for a record is 0.
Soon a developer decided to implement this idea to earn this reward, on April 18, Namecoin was introduced by Vinced as a multipurpose and distributed naming system based on bitcoin.
Two years later, in June , NameID was launched and it is a service to associate profile information with identities on the Namecoin blockchain and an OpenID provider to allow logging into existing websites with Namecoin identities. The main site itself is accompanied by a protocol for password-less authentication with Namecoin identities, a corresponding free-software implementation. In October , Michael Gronager, main developer of libcoin, found a security issue in the Namecoin protocol and it was successfully fixed in a short timeframe and was never exploited, except for bitcoin.
Titcoin — Titcoin is a derivative of the bitcoin source code with key modifications to the software which greatly improve transaction speeds and network difficulty readjustments. Titcoin is notable for being the first altcoin fully recognized as a form of currency by a major industry trade organization. In , Titcoin received two nominations at the XBIZ Awards ceremony which honors companies that play a part in the growth.
The founders developed Titcoin for the entertainment industry as a cash alternative payment system for performing anonymous transactions. Titcoin allows consumers of adult entertainment to perform transactions without using any personally identifiable information, Titcoin also benefits adult businesses with zero chargebacks and freedom from dealing with traditional financial institutions. On January 17,, Titcoin was formally revealed to the community with initial coin specifications.
On June 21,, the Titcoin wallet and source code was released with a soft launch for the cryptocurrency community followed by a hard launch for the public. Titcoin is a clone that leverages the same SHA set of cryptographic hash functions. Titcoin has received award nominations and ratings from notable organizations within the adult entertainment.
Ethereum — Ethereum is an open-source, public, blockchain-based distributed computing platform featuring smart contract functionality. It provides a decentralized Turing-complete virtual machine, the Ethereum Virtual Machine, Ethereum also provides a value token called ether, which can be transferred between participants and is used to compensate participant nodes for computations performed.
Gas, an internal transaction pricing mechanism, is used to prevent spam on the network, Ethereum was initially proposed in late by Vitalik Buterin, a cryptocurrency researcher and programmer.
Development was funded by an online crowdsale during July—August , the system went live on 30 July Ethereum was initially described in a paper by Vitalik Buterin. More specifically, Buterin had argued to the core developers that the platform needed a more robust scripting language for developing applications. Failing to gain agreement, he proposed development of a new platform with a more general scripting language, Buterin believes that many applications could benefit from Bitcoin-like software.
The Ethereum software project was developed in early by a Swiss company. Subsequently, a Swiss non-profit foundation, the Ethereum Foundation was set up as well, development was funded by an online public crowdsale during July—August , with the participants buying the Ethereum value token with another digital currency, bitcoin. While there was praise for the technical innovations of Ethereum. Ethereums live blockchain was launched on 30 July , the initial version of Ethereum—called Frontier—uses a proof of work consensus algorithm, although a later version is expected to replace that with a proof of stake algorithm.
Since the initial version, the Ethereum network has accomplished several so-called hard forks, first hard fork The first hard fork introduced a difficulty bomb to incentivize an upgrade to proof of stake when this system will be ready.
Second hard fork—Homestead release The second hard fork was made in Spring and marked the first stable release, as a consequence of the way the DAO was programmed, these moved funds would remain unavailable for withdrawal for about a month. After a few weeks discussion, on 20 July Ethereum hard-forked creating a new fork to reverse the hack and return The DAO funds and this was the first time any mainstream blockchain was forked to reverse a transaction in order to make reparations to investors in a failed enterprise.
This hard fork successfully de-bloated the blockchain and attempted to prevent further attacks by hackers. The value token of the Ethereum blockchain is called ether and it is listed under the diminutive ETH and traded on cryptocurrency exchanges. It is also used to pay for fees and computational services on the Ethereum network. Wiki as never seen before with video and photo galleries, discover something new today.
