MINIX 3 was announced to the public on 24 October 2005 by Andrew Tanenbaum during his speech on top of the ACM Symposium Operating System Principles conference. MINIX 3 currently supports only IA-32 architecture PC systems. It has a Live CD format that lets it be used on a computer without installing it.
Version 3.1.2 was released 8 May 2006. It contains X11, emacs, vi, cc, gcc, perl, python, ash, bash, zsh, ftp, ssh, telnet, pine, and over 400 other common UNIX programs. With the addition of X11, this version starts the change from a Text-Only System.
The design principles Tanenbaum applied to MINIX had influenced the design decisions Linus Torvalds applied in the creation of the Linux kernel. Torvalds used and appreciated MINIX, but his design was different from the MINIX architecture in significant ways, most notably by employing a monolithic kernel instead of a microkernel. This was famously disapproved by Tanenbaum in the Tanenbaum-Torvalds debate. (Tanenbaum explained again his rationale for using a microkernel in May 2006.)
In May 2004 Kenneth Brown of the Alexis de Tocqueville Institution raised the accusation that major parts of the Linux kernel had been copied from MINIX, in a book called "Samizdat".
These accusations were refused by almost everyone - in particular by Andrew Tanenbaum, who strongly felt that Kenneth Brown was very wrong and published a long rebuttal on his own personal website.
Its licensing fee was very small ($69) compared to the ones of other operating systems. Although Tanenbaum wished for MINIX to be as easily available to students, his publisher would not allow it.
When free/open source Unix-like operating systems such as Linux became available in the early 1990s, many volunteer software developers stopped using MINIX for Linux. In April 2000, MINIX became free/open source software under a permissive free software licence, but by this time other operating systems were much better, and it was mostly used as an operating system for students and hobbyists.
Causality
Causality is a way to describe how different events relate to one another. Suppose there are two events "A" and "B". If "B" happens because "A" happened, then people say that A "is the cause" of B, or that B "is the effect of" A.
What looks very simple, is in fact a difficult problem. Many people have tried to solve it, they have come up with different solutions
Aristotle was a Greek philosopher. He also looked at the problem of causality. In his books "Posterior analytics" and "Metaphysics" he wrote:
This can be used to explain causality. Aristotle found different kinds of causes:
Aristotle told people of two types of causes: proper (prior) causes and accidental (chance) causes. Both types of causes, can be spoken as potential or as actual, particular or generic. The same language refers to the effects of causes; so that generic effects assigned to generic causes, particular effects to particular causes, and operating causes to actual effects. It is also essential that ontological causality does not suggest the temporal relation of before and after - between the cause and the effect; that spontaneity (in nature) and chance (in the sphere of moral actions) are among the causes of effects belonging to the efficient causation, and that no incidental, spontaneous, or chance cause can be prior to a proper, real, or underlying cause "per se".
All investigations of causality coming later in history will consist in imposing a favorite hierarchy on the order (priority) of causes; such as "final > efficient > material > formal" (Aquinas), or in restricting all causality to the material and efficient causes or, to the efficient causality (deterministic or chance), or just to regular sequences and correlations of natural phenomena (the natural sciences describing "how" things happen rather than asking "why" they happen).
David Hume was another philosopher who looked at the relation between cause and effect. Hume thinks that there are certain things all such relations of cause and effect have in common.:
Hume says that if someone is used to always seeing the same things occur in the same order, he will get accustumed to them being in that order. When he sees one event occur, he will expect the other to occur as well:
Logic is the science that looks at how to build an argument. In Logic, there are usually two different types of causes. They are called "necessary cause" and "sufficient cause".
Wildhaus
Wildhaus is a village and municipality near St. Gallen in the canton of St. Gallen in Switzerland. About 1,200 people live there. Huldrych Zwingli was born there in 1484. With "9658", Wildhaus has the highest zip code in Switzerland. On 1 January 2010 the former municipalities of Wildhaus and Alt St. Johann merged into the new municipality of Wildhaus-Alt St. Johann.
Muhammad Iqbal
Sir Muhammad Iqbal (November 9, 1877 – April 21, 1938), widely known as Allama Iqbal, was a Muslim poet and philosopher. Allama Iqbal gave the idea of Pakistan. He became the national poet of Pakistan. He is also known as the poet of East. He wrote poetry in Urdu and Persian. His poetry is considered to be revolutionary. His vision of an independent state for the Muslims of British India was a starting point for the creation of Pakistan. He is commonly referred to as Dr Allama Muhammad Iqbal.
Muhammad Iqbal was born on 9 November 1877. His father was Sheikh Noor Muhammad, who worked in a small government job but later started his own business, and his mother was Imam Bibi. Both Allama Iqbal's mother and father were very pious and religious-minded people and devoted to a simple life. After early Islamic education and then secondary at a small school in Sialkot, Iqbal was admitted to the Scottish Murray College, Sialkot, where he topped the higher secondary examinations and got a scholarship to study at the famous Government College, Lahore, for BA. On going to live in the hostel there, Iqbal met Professor Arnold, an English teacher who taught many things to Iqbal and guided him in his studies of philosophy and literature. He was very young at that time.
At that time, Iqbal also became well known as a new poet and writer. He used to go to attend the 'Mushaira' at the haveli of Hakim Syed Aminuddin, in BhaatiGate area of Old Lahore city—hekre, he met many famous poets and writers and also began to write good poems which became very popular. He was guided by Mirza Dagh. His first famous poem, "Koh i Himala" was also printed in Makhzan magazine, owned by Hakim Shuja uddin and Sir Abdul Qadir
After doing his BA and MA from Government College, Lahore, Iqbal was appointed a professor at this same institution and after some time, in 1905, he was selected for higher studies in England and Europe. He went and studied in Cambridge University and then also law at University of London, and then he went to Munich, Germany, where he took a PHD degree. After all his study, Iqbal decided to go back and teach and also practice law in India.
At that time he faced many difficulties.Although faced by some of the difficulties, Iqbal followed this plan. He taught some senior classes at Government College and also practiced Law at Lahore High Court. At the same time, he wrote many famous poems such as "Asrar i Khudi", "Ramuz i Bekhudi", "Payam i Mashriq", "Zabur i Ajam", "Bang i Dara", "Bal i Jibrail and" etc. Because of his learning and knowledge, people soon began to call him 'Allama' Iqbal and in 1922, King George V of Britain, giving him the title of Allama 'Sir' Muhammad Iqbal. He was awarded 5 awards.
