Coldplay: Biography

Coldplay are a British rock band formed in 1996 by lead vocalist Chris Martin and lead guitarist Jonny Buckland at University College London. After they formed Pectoralz, Guy Berryman joined the group as a bassist and they changed their name to Starfish. Will Champion joined as a drummer, backing vocalist, and multi-instrumentalist, completing the line-up. Manager Phil Harvey is often considered an unofficial fifth member. The band renamed themselves "Coldplay" in 1998, before recording and releasing three EPs; Safety in 1998, Brothers & Sisters as a single in 1999 and The Blue Room in the same year. The latter was their first release on a major label, after signing to Parlophone.


They achieved worldwide fame with the release of the single "Yellow" in 2000, followed by their debut album released in the same year, Parachutes, which was nominated for the Mercury Prize. The band's second album, A Rush of Blood to the Head (2002), was released to critical acclaim and won multiple awards, including NME's Album of the Year, and has been widely considered the best of the Nelson-produced Coldplay albums. Their next release, X&Y, the best-selling album worldwide in 2005, was met with mostly positive reviews upon its release, though some critics felt that it was inferior to its predecessor. The band's fourth studio album, Viva la Vida or Death and All His Friends (2008), was produced by Brian Eno and released again to largely favourable reviews, earning several Grammy nominations and wins at the 51st Grammy Awards. On 24 October 2011, they released their fifth studio album, Mylo Xyloto, which topped the charts in over 34 countries, and was the UK's best-selling rock album of 2011

Explain the purpose, nature, function and operations of Symmetric Encryption Principles. What are the essential ingredients of a symmetric cipher? Differentiate between encryption and decryption.

Symmetric encryption is a class of algorithms for cryptography that use the same cryptographic keys for both encryption of plaintext and decryption of ciphertext. The keys may be identical or there may be a simple transformation to go between the two keys. The keys, in practice, represent a shared secret between two or more parties that can be used to maintain a private information link.

Encryption methods can be extremely efficient, requiring minimal processing, and Both sender and receiver must possess encryption key. If either copy of key is compromised, an intermediate can decrypt and read messages

A symmetric encryption has two components a block cipher and stream cipher. (i) A block cipher operates on groups of bits – typically groups of 64. If the final block of the plaintext message is shorter than 64 bits, it is padded with some regular pattern of 1s and 0s to make a complete block. Block ciphers encrypt each block independently, so the plaintext does not have to be processed in a sequential manner. (ii) A stream cipher generally operates on one bit of plaintext at a time, although some stream ciphers operate on bytes. A component called a keystream generator generates a sequence of bits, usually known as a keystream. In the simplest form of stream cipher, a modulo-2 adder (exclusive-OR or XOR gate) combines each bit in the plaintext with each bit in the keystream to produce the ciphertext. At the receiving end, another modulo-2 adder combines the ciphertext with the keystream to recover the plaintext.

A symmetric encryption has 5 ingredients, which are the following:

1.                 Plaintext: this is the original message or data that is fed into the algorithm as input.

2.                 Encryption algorithm: this algorithm performs various substitutions and transformations on the plaintext.

3.                 Secret Key: is also input to algorithm. The exact substitutions and transformations performed by the algorithm depend on the key.

4.                 Ciphertext: this is the scrambled message produced as output. It depends on the plaintext and secret key.

5.                 Decryption algorithm: this is essentially the encryption algorithm run in reverse. It takes the ciphertext and the same secret key and produces the original plaintext.

Provide several examples of IPSec. What services are provided by IPSec? What is the difference between Transport Mode and Tunnel Mode?

IPSec (Internet Protocol Security) is a capability that can be added to either current version of the internet protocol by means of additional headers. IPsec encompasses three functional areas authentication, confidentiality, and key management.

IPSec provides the capability to secure communications across a LAN, Private and public WANs, and across the internet. Examples of IPSec include the following:

Secure branch office connectivity over the internet: a company can build a secure virtual private network over the internet or over a public WAN. This enables a business to rely heavily on the internet and reduce its need for private networks, saving costs and network management overhead.

Another example of internet protocol security is secure remote access over the internet. On this case, an end user whose system is equipped with IP security protocols can make a local call to an internet service provider and gain secure access to a company network. This reduces the cost of toll charges for travelling employees and telecommuters.

Last but not least, enhancing electronic commerce security, even though some web and electronic commerce applications have built-in security protocols, the use of IPSec enhances that security.

The IPSec provides security services at the IP layer enabling a system to select required security protocols, determine the algorithms to use for services, and put in place any cryptographic keys required to provide the request services. The services provided by the IPSec are the following:

·         Access control

·         Connectionless integrity

·         Data origin authentication

·         Rejection of replayed packets (a form of partial sequence integrity)

·         Confidentiality (encryption)

·         Limited traffic flow confidentiality

The IPsec standards define two distinct modes of IPsec operation, transport mode and tunnel mode. The modes do not affect the encoding of packets. The packets are protected by AH, ESP, or both in each mode. The modes differ in policy application when the inner packet is an IP packet, as follows:

·                    In transport mode, the outer header determines the IPsec policy that protects the inner IP packet.

·                    In tunnel mode, the inner IP packet determines the IPsec policy that protects its contents.

In transport mode, the outer header, the next header, and any ports that the next header supports, can be used to determine IPsec policy. In effect, IPsec can enforce different transport mode policies between two IP addresses to the granularity of a single port. For example, if the next header is TCP, which supports ports, then IPsec policy can be set for a TCP port of the outer IP address. Similarly, if the next header is an IP header, the outer header and the inner IP header can be used to determine IPsec policy.

Tunnel mode works only for IP-in-IP datagrams. Tunneling in tunnel mode can be useful when computer workers at home are connecting to a central computer location. In tunnel mode, IPsec policy is enforced on the contents of the inner IP datagram. Different IPsec policies can be enforced for different inner IP addresses. That is, the inner IP header, its next header, and the ports that the next header supports, can enforce a policy. Unlike transport mode, in tunnel mode the outer IP header does not dictate the policy of its inner IP datagram.

Why are so many companies opting for Joint -Venture?

A joint venture is a long-term participation of two or more companies in an enterprise in which each party contributes with assets, has equity participation and shares risk (Alliances and Joint Ventures, 2006).

Many companies are opting for this entry because it allows companies to improve efficiency and create economies of scale and scope while spreading the risk between the partners. It also gives the MNC access to the knowledge of its local partner that will help them better understand the market and its customers in that region, as well as the political issues going on in the region. It also lets the MNC overcome limits on foreign companies by becoming part of the insider group.

A fully owned company faces a high risk with such a large investment in one area. Moreover, many countries forbid this kind of entry, because they believe that a fully owned company will drive out local enterprises. Moreover, the home-country unions sometimes oppose the creation of subsidiaries, which they see as an attempt to export jobs, particularly when the MNC exports good for another country and then decides to set up manufacturing operations there (Fred Luthans, 2009).

What do U.S. managers need to know about leading in the international arena?

As countries become more economically advanced, participative styles may well gain in importance. This does not mean that MNCs can use the same leadership styles in their various operations around the world. There must always be careful contingency application of leadership styles. That is, the style of leadership that is successful depends on the situation the leader faces.

Cultural differences do play an extremely important role in effective leadership, however, and must be carefully considered when leading people in different countries. For instance, in countries where there never was a private investment, most of the managers do not have the experience of leading a big organization, in addition, they may not help a MNC achieves its goals, because they are used to work for the government. In this case, the appropriate leadership style would be an autocratic.

When U.S managers are in Japan, if they want to have high achievement the leadership style that emphasized both task and human dimensions is the most effective. However, among low achieving groups, the leadership style that is most effective is the one which focuses highly on task and low on the human dimensions.

Futebol familiar: 21-Jul-12

A tarde de sábado foi marcada com a segunda partida do futebol familiar, desta vez o recinto escolhido foi o campo da Vila do GAMEK. A partida teve inicio as 11:05min, com o time do viti contra o time do Cajo. No time do Viti alinhou: Gilson, Fefe, Mack, Indio, e Viti. Por outro lado no time do Cajo alinhou: Leu, Mango, Careca, Benvindo e Cajo.

O time do viti cilindrou o time do cajo com 6 bolas a três. Foi uma partida muito emotiva, com bastante equilíbrio nos primeiros quinze minutos, contudo depois a supremacia do time do viti veio acima, vendo o Fefe a fazer um hac-trick, e Gilson apontando um golo, e o Indio a completar a goleada. Pro time do cajo marcaram : Leu por duas vezes e mango por uma. 

Luanda: Praças em todo lado

Na cidade capital parece que todo lugar só da praça, o numero de praças tem aumentado em locais públicos como, por exemplo, debaixo do viaduto da Samba (N’zamba 2), na entrada do Talatona, no mundo verde.

Na passagem aérea da Rocha já não se fala e um congo. Próximo ao mercado congolense, na passadeira área já não há espaços pra as pessoas. 

Pobreza em Angola

Angola e um dos paises mais rico do mundo em termos de recursos naturais, como e o caso de combustiveis fosseis (Petroleo), recursos hidricos, recursos florestais, recursos marinhos, e outros recursos minerais.

Com tanto recurso que existe nessa terra, a divisao de riqueza ainda e feita de uma maneira estranha, apenas alguns apoderam-se desse precioso recurso, mantendo assim a maioria da populacao a viver com menos de um dolar dia. Como nao se basta-se a ma divisao da riqueza, Angola e um dos paises mais caros pra se viver.

OH! Meu Deus essa e a terra aonde fomos nascer. Como mudar esse quadro?
