CASE 466 - The history of The Czech republic



Despite its landlocked location, there were brief periods in the Middle Ages during which Bohemia had access to the Baltic and Adriatic seacoasts. A region of rolling hills and mountains, Bohemia is dominated by the national capital, Prague. Set on the Vltava River, this picturesque city of bridges and spires is the unique work of generations of artists brought in by the rulers of Bohemia. Perhaps only the French are as focused on their capital, Paris, as the Czechs are on theirs; of the two, Prague has a more magical quality for many. Called “the handsomest city of Europe” since the 18th century, it has intoxicated writers, poets, and musicians alike. While Prague was the birthplace of the writer Franz Kafka and the poet Rainer Maria Rilke, Brno, Moravia’s largest city, was the site of Gregor Mendel’s groundbreaking genetic experiments in the 19th century and the birthplace of contemporary novelist Milan Kundera. Moravians are as proud of their vineyards and wine as Bohemians are of their breweries and the Pilsner beer that originated in the town of Plzeň (Pilsen), which is also noted as the site of the Škoda Works—a heavy industrial complex that originated with the Habsburg monarchy. Moravia was equally endowed with skilled labour, which helped make Brno into one of the leading industrial towns in textiles and engineering during the 19th century and Ostrava, in the north, into a major coal-mining region, thanks to the vast fossil fuel deposits stretching over from Silesia.



During its 1,000-year history, The czech republic, formally Czechoslovakia has changed shape and reshuffled its population a few times. As the kingdom of Bohemia, it reached its zenith of wealth and power during the 13th and 14th centuries. Through a multitude of cultural, economic, ecclesiastical, and dynastic links, Bohemian kings became directly involved in the affairs of the German rulers of the Holy Roman Empire and opened the country to German colonization, which brought prosperity through silver mining and rapid urbanization. Prague, with the oldest university north of the Alps (Charles University, 1348), functioned as a royal and imperial capital. However, German colonization, which soon accounted for one-third of the total population and disadvantaged the majority Czechs, brought the seeds of discontent, resulting in an ugly, insolvable conflict in the 20th century. In the early 15th century Bohemia witnessed the Hussite revolution, a pre-Reformation movement named for Jan Hus, a follower of the English theologian and reformer John Wycliffe. Religious antagonism prevailed over ethnic tensions when Czechs and Germans jointly led the Protestant uprising that started the Thirty Years’ War (1618–48) against the Catholic Habsburgs, the Austro-German dynasty that ruled Bohemia from 1526 to 1918. After the Habsburg victory, the German language replaced Czech for almost two centuries—until the Czechs experienced an extraordinary linguistic and cultural revival that coincided with the revolutions of 1848 and the spread of industrialization.



The collapse of the Austro-Hungarian Empire at the end of World War I brought the Czechs and Slovaks together for the first time as “Czechoslovaks.” The Czechs became the ruling ethnic group in Czechoslovakia, a new state in which Germans and Hungarians lived as unwilling citizens, bound to become disloyal minorities bent on undermining the democratic constitution engendered by the country’s founders, Tomáš G. Masaryk and Edvard Beneš. Many among this German population turned into Nazi sympathizers with the ascent to power of Adolf Hitler in Germany, whose design on the German-speaking border region of Czechoslovakia was appeased by England and France in the Munich Agreement of September 1938. Emasculated, Czechoslovakia succumbed to direct German invasion six months later. Bohemia and Moravia became a protectorate of the “Greater German Empire,” while Slovakia—whose Hungarian districts were ceded to Hungary—was induced by Hitler to proclaim its independence. After six years of brutal Nazi occupation, Czechoslovakia was reconstituted, this time without Ruthenia (Transcarpathian Ukraine), which was annexed by the Soviet Union. A communist coup in February 1948 sealed Czechoslovakia’s fate as a member of the Soviet bloc for the entire Cold War—though briefly, in the Prague Spring of 1968, a reform movement took over, only to be crushed by Soviet military invasion in August of that year. Still, that experience of freedom produced an underground dissident movement, later called Charter 77, whose leader, playwright Václav Havel, was propelled from prison to the royal castle, becoming the first president of postcommunist Czechoslovakia with the fall of the Berlin Wall in 1989.

CASE 465 - Bitcoin and the future of currency



Bitcoin is a cryptocurrency and a payment system invented by an unidentified programmer, or group of programmers, under the name of Satoshi Nakamoto. Bitcoin was introduced on 31 October 2008 to a cryptography mailing list, and released as open-source software in 2009. There have been various claims and speculation concerning the identity of Nakamoto, none of which are confirmed. 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, which uses bitcoin as its unit of account. Since the system works without a central repository or single administrator, the U.S. Treasury categorizes bitcoin as a decentralized virtual currency. Bitcoin is often called the first cryptocurrency, although prior systems existed and it is more correctly described as the first decentralized digital currency. Bitcoin is the largest of its kind in terms of total market value and is a cross between a stock and a form of payment. It’s a form of payment because you can use Bitcoins to pay for things. You can buy computers on Tigerdirect.com, you can buy pretty much get anything on Overstock.com OSTK -1.97%, and apparently, some enterprising young California girls are letting you buy cookies with them. You can also send small amounts of currency to people in other countries, without worrying about exchange rates or currency conversion fees. And this last is pretty important. No currency conversion or exchange rates.

It’s a stock because there’s a fixed number of “Bitcoins” in the universe. The value of each Bitcoin fluctuates based on the law of supply and demand. The more people that want to use them, the higher their value. One friend anecdotally reported Bitcoins bought in 2009-2010 for $1 (USD) each were recently sold for $1,200. That’s a lot of appreciation. But it’s not what Bitcoin’s people focus on.



Fiat currency ($£) is created through bank loans and mortgages (debts), out of thin air without having to have physical cash or it be backed by anything. This allows central banks to expand and influence money in circulation without regulation. As long the debter pays off the inflation and minimum requirement payment. There will never be enough money in society to ever pay all the debts off so a disequilibrium occurs where people become detached from their original debt and society constantly has to compete for labor in order to pool enough money out of the continual growth economy money supply and it's not backed or pegged by anything other peoples faith and trust and our national insurance, also u can get mugged in the street with cash or through your bank account or stick it in the Cayman Islands to avoid paying tax. Where as bitcoin it's not impossible but you would need a quantum computer to hack the encryption that it uses, which is also regulated and taxed in units of transactions and it essentially does away with the central bank model and tax evaders, I can buy something off a person on the other side of the world without having to go through say PayPal and then my bank



Blockchain

Number of unspent transaction outputs

The blockchain is a public 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. Network nodes can validate transactions, add them to their copy of the ledger, and then broadcast these ledger additions to other nodes. The blockchain is a distributed database – to achieve independent verification of the chain of ownership of any and every bitcoin (amount), each network node stores its own copy of the blockchain. Approximately six times per hour, a new group of accepted transactions, a block, is created, added to the blockchain, and quickly published to all nodes. This allows bitcoin software to determine when a particular bitcoin amount has been spent, which is necessary in order to prevent double-spending in an environment without central oversight. Whereas a conventional ledger records the transfers of actual bills or promissory notes that exist apart from it, the blockchain is the only place that bitcoins can be said to exist in the form of unspent outputs of transactions.

Units

The unit of account of the bitcoin system is bitcoin. As of 2014, symbols used to represent bitcoin are BTC, XBT and BitcoinSign.svg. Small amounts of bitcoin used as alternative units are millibitcoin (mBTC), microbitcoin (µBTC, sometimes referred to as a bit), and satoshi. Named in homage to bitcoin's creator, a satoshi is the smallest amount within bitcoin representing 0.00000001 bitcoin, one hundred millionth of a bitcoin. A millibitcoin equals to 0.001 bitcoin, one thousandth of bitcoin. One microbitcoin equals to 0.000001 bitcoin, one millionth of a bitcoin.

A proposal was submitted to the Unicode Consortium in October 2015 to add a codepoint for the symbol. As of November 2016, it is in the pipeline for position 20BF in the Currency Symbols block.

Ownership

Simplified chain of ownership. In reality, a transaction can have more than one input and more than one output.

Ownership of bitcoins implies that a user can spend bitcoins associated with a specific address. To do so, a payer must digitally sign the transaction using the corresponding private key. Without knowledge of the private key, the transaction cannot be signed and bitcoins cannot be spent. The network verifies the signature using the public key. If the private key is lost, the bitcoin network will not recognize any other evidence of ownership; the coins are then unusable, and thus effectively lost. For example, in 2013 one user claimed to have lost 7,500 bitcoins, worth $7.5 million at the time, when he accidentally discarded a hard drive containing his private key.

Transactions

A transaction must have one or more inputs. For the transaction to be valid, every input must be an unspent output of a previous transaction. Every input must be digitally signed. The use of multiple inputs corresponds to the use of multiple coins in a cash transaction. A transaction can also have multiple outputs, allowing one to make multiple payments in one go. A transaction output can be specified as an arbitrary multiple of satoshi. As in a cash transaction, the sum of inputs (coins used to pay) can exceed the intended sum of payments. In such a case, an additional output is used, returning the change back to the payer. Any input satoshis not accounted for in the transaction outputs become the transaction fee.

Mining

Mining is a record-keeping service. Miners keep the blockchain consistent, complete, and unalterable by repeatedly verifying and collecting newly broadcast transactions into a new group of transactions called a block. Each block contains a cryptographic hash of the previous block, using the SHA-256 hashing algorithm, 7 which links it to the previous block, thus giving the blockchain its name. In order to be accepted by the rest of the network, a new block must contain a so-called proof-of-work. The proof-of-work requires miners to find a number called a nonce, such that when the block content is hashed along with the nonce, the result is numerically smaller than the network's difficulty target. 8 This proof is easy for any node in the network to verify, but extremely time-consuming to generate, as for a secure cryptographic hash, miners must try many different nonce values (usually the sequence of tested values is 0, 1, 2, 3, ... 8) before meeting the difficulty target.

Every 2016 blocks (approximately 14 days), the difficulty target is adjusted based on the network's recent performance, with the aim of keeping the average time between new blocks at ten minutes. In this way the system automatically adapts to the total amount of mining power on the network.

Between 1 March 2014 and 1 March 2015, the average number of nonces miners had to try before creating a new block increased from 16.4 quintillion to 200.5 quintillion.

The proof-of-work system, alongside the chaining of blocks, makes modifications of the blockchain extremely hard, as an attacker must modify all subsequent blocks in order for the modifications of one block to be accepted. As new blocks are mined all the time, the difficulty of modifying a block increases as time passes and the number of subsequent blocks (also called confirmations of the given block) increases



We need to maintain and improve upon our already-powerful open-source, cryptographic algorithms and enhance the programs , start ups and ideas being brought forward by young people. We need to fight to encode privacy and our human rights into the very fabric of the world. Edward Snowden said so himself. It is actually part of what spurred him on in divulging the crimes of the NSA and other government agencies

Snowden’s goal for us is to create a more free and equal internet. In an earlier interview with Laura Pointras, Snowden explained:

“The shock of this initial period [after the first revelations] will provide the support needed to build a more equal internet, but this will not work to the advantage of the average person unless science outpaces law. By understanding the mechanisms through which our privacy is violated, we can win here. We can guarantee for all people equal protection against unreasonable search through universal laws, but only if the technical community is willing to face the threat and commit to implementing over-engineered solutions. In the end, we must enforce a principle whereby the only way the powerful may enjoy privacy is when it is the same kind shared by the ordinary: one enforced by the laws of nature, rather than the policies of man.”

By implementing these new cryptographic systems, we may move one step further towards what Snowden envisioned: distributed and secure math-based ecosystems that enhance our privacy and allow us to innovate further in all areas — in government, in finance, in communications, agriculture, building and journalism, etc. Even if you inherently trust our government — I would argue that the price of non-action here is great: Dictators around the world, future corrupt leaders of America, they all stand to benefit if citizens are denied these tools. The old democratic 2 or 3 party highest voted party wins system or constant growth fractional reserve centralized banking systems has and never will work or be fair for everyone and its so expensive, wasteful, uneconomic, creates a higher rich/poor gap and political actions always take years to implement, but an open source cryptographic governence/financial world were absolutely everyone has a say and input, everything is transparent and there to be Search Results analyzed by anyone if they want to could.

CASE 464 - Al Qaeda / ISIS - Terrorism by proxy



As this latest Western manufactured ‘terror nightmare’ continues to unfold in Iraq and Syria, we’ve learned that US President Barack Obama has now asked Congress to authorize direct military aid and equipment to be sent to ‘the rebels’ in Syria. This latest stage of Washington’s project in Syria is said to total $500 million, expanding the covert CIA/FSA training facilities that have ties to ISIS in both Jordan and Turkey… The mainstream media has been spinning overtime with ISIS, touting many dramatic pictures of mass-executions as ‘evidence’ of their takeover of Iraq, and using this crisis yet another pretext to ramp-up military budgets and security threats at home. Most of the ‘mass execution’ images put forward in media have since been exposed as pure fakery, although this hasn’t deterred US and European media ‘experts’ or US State Department, UK Foreign Office officials, tabloid newspapers and news channels. As the ‘ISIS Crisis’ appears to spiral out of control, it exposes the Western government-transnational corporate agenda, that seeks to expand the current proxy war in Iraq, as well as to neighboring nations by directly financing terror rebels – this time with Congressional approval. While many think-tanks and media rooms proclaim to be very much against the terror-grip of Al-Qaeda’s offshoot ISIS by publicly denounce their actions, the $500 million dollar appropriation appears to be a cash injection into the radical destruction of both Iraq and Syria. The current destabilization campaign in Iraq will have a number of unforeseen outcomes, including the fracturing of Syria and Iraq, and the predictable calls from Erbil for a newly formed ‘Kurdish State’ in Northern Iraq.



Islamic State and by its Arabic language acronym Daesh داعش‎‎ is a Salafi jihadist unrecognised state and militant group that follows a fundamentalist, Wahhabi doctrine of Sunni Islam. ISIL gained global notoriety in early 2014 when it drove Iraqi government forces out of key cities in its Western Iraq offensive,[49] followed by its capture of Mosul and the Sinjar massacre. Its adoption of the name Islamic State and its idea of a caliphate have been widely criticised, with the United Nations, various governments, and mainstream Muslim groups rejecting its statehood. This group has been designated a terrorist organisation by the United Nations and many individual countries. ISIL is widely known for its videos of beheadings of both soldiers and civilians, including journalists and aid workers, and its destruction of cultural heritage sites. The United Nations holds ISIL responsible for human rights abuses and war crimes, and Amnesty International has charged the group with ethnic cleansing on a "historic scale" in northern Iraq. In Syria, the group has conducted ground attacks on both government forces and opposition factions. By December 2015, the Islamic State covered a vast landlocked territory in western Iraq and eastern Syria, with a population estimate of 2.8–8 million people, where it enforces its interpretation of sharia law. ISIL is now believed to be operational in 18 countries across the world, including Afghanistan and Pakistan, with "aspiring branches" in Mali, Egypt, Somalia, Bangladesh, Indonesia and the Philippines.



US, Turkey, Israel and Saudi-backed Terrorist Groups Coming Out of Syria

Known terrorist groups have been operating in Syria for over three years now – mostly with the tacit approval of war planners in Washington, London and Paris. Folded into the ‘Syrian Rebel’ confab, these terrorist fighting groups have all but received the full backing of NATO Allies (arms) and Gulf states Qatar and Saudi Arabia (money). They include, but are not limited to, Saudi Intelligence-backed Jabhat al-Nusra or ‘al Nursa Front’, the Libyan Islamic Fighting Group, Abdullah Azzam Brigades and Al Baraa ibn Malik Martyrdom Brigade, the jihadist group Ahrar al-Sham, the PKK (in northeast Syria), and Kata’ib Mohadzherin from the Russian Caucus region – to name only a few.



SIS, ISIL, IS or Daesh – the group has been deliberately engineered by the US, Turkey, Saudi Arabia and Israel to achieve certain geopolitical goals. They are a religious, fundamentalist, Sunni terrorist organization created to terrorize and overthrow certain secular or Shiite Arab nations such as Syria and Iraq, but they are not just “Islamic” and it always always seems to be in favor of the Israeli state. It has systemically tried to divide and conquer its Arab neighbors. It continually complains of Islamic terrorism. Yet, when ISIS comes on the scene as the bloody and barbaric king of Islamic terrorism, it finds no fault with Israel and sees no reason to target a regime which has perpetrated massive injustice against Muslims? This stretches credibility to a snapping point. ISIS and Israel don’t attack each other – they help each other. Israel was treating ISIS soldiers and other anti-Assad rebels in its hospitals! Mortal enemies or best of friends?
