linux commands Linux For Beginners Guide To Learn Linux Command Line, Linux Operating System And Linux CommandsIntroductionI want to tell you a story.No, not the story of how, in 1991, Linus Torvalds wrote the first version of the Linux ker-nel. You can read that story in lots of Linux books. Nor am I going to tell you the story ofhow, some years earlier, Richard Stallman began the GNU Project to create a free Unix-like operating system. That's an important story too, but most other Linux books have thatone, as well.No, I want to tell you the story of how you can take back control of your computer.When I began working with computers as a college student in the late 1970s, there was arevolution going on. The invention of the microprocessor had made it possible for ordi-nary people like you and me to actually own a computer. It's hard for many people todayto imagine what the world was like when only big business and big government ran allthe computers. Let's just say, you couldn't get much done.Today, the world is very different. Computers are everywhere, from tiny wristwatches togiant data centers to everything in between. In addition to ubiquitous computers, we alsohave a ubiquitous network connecting them together. This has created a wondrous newage of personal empowerment and creative freedom, but over the last couple of decadessomething else has been happening. A few giant corporations have been imposing theircontrol over most of the world's computers and deciding what you can and cannot dowith them. Fortunately, people from all over the world are doing something about it. Theyare fighting to maintain control of their computers by writing their own software. Theyare building Linux.Many people speak of "freedom" with regard to Linux, but I don't think most peopleknow what this freedom really means. Freedom is the power to decide what your com-puter does, and the only way to have this freedom is to know what your computer is do-ing. Freedom is a computer that is without secrets, one where everything can be known ifyou care enough to find out.Why Use The Command Line?Have you ever noticed in the movies when the "super hacker,"-you know, the guy whocan break into the ultra-secure military computer in under thirty seconds-sits down atthe computer, he never touches a mouse? It's because movie makers realize that we, ashuman beings, instinctively know the only way to really get anything done on a computerxviis by typing on a keyboard!Most computer users today are only familiar with the graphical user interface (GUI) andhave been taught by vendors and pundits that the command line interface (CLI) is a terri-fying thing of the past. This is unfortunate, because a good command line interface is amarvelously expressive way of communicating with a computer in much the same waythe written word is for human beings. It's been said that "graphical user interfaces makeeasy tasks easy, while command line interfaces make difficult tasks possible" and this isstill very true today.Since Linux is modeled after the Unix family of operating systems, it shares the samerich heritage of command line tools as Unix. Unix came into prominence during the early1980s (although it was first developed a decade earlier), before the widespread adoptionof the graphical user interface and, as a result, developed an extensive command line in-terface instead. In fact, one of the strongest reasons early adopters of Linux chose it over, say, Windows NT was the powerful command line interface which made the "difficulttasks possible

Basics of PhilosophyBasics of Philosophy For beginnersAt its simplest, philosophy (from the Greek phílosophía or phílosophía, meaning 'the love of wisdom') is the study of knowledge, or "thinking about thinking", although the breadth of what it covers is perhaps best illustrated by a selection of other alternative definitions: the discipline concerned with questions of how one should live (ethics); what sorts of things exist and what are their essential natures (metaphysics); what counts as genuine knowledge (epistemology); and what are the correct principles of reasoning (logic) (Wikipedia)investigation of the nature, causes, or principles of reality, knowledge, or values, based on logical reasoning rather than empirical methods (American Heritage Dictionary)the study of the ultimate nature of existence, reality, knowledge and goodness, as discoverable by human reasoning (Penguin English Dictionary)the rational investigation of questions about existence and knowledge and ethics (WordNet)the search for knowledge and truth, especially about the nature of man and his behavior and beliefs (Kernerman English Multilingual Dictionary)the rational and critical inquiry into basic principles (Microsoft Encarta Encyclopedia)the study of the most general and abstract features of the world and categories with which we think: mind, matter, reason, proof, truth, etc. (Oxford Dictionary of Philosophy)careful thought about the fundamental nature of the world, the grounds for human knowledge, and the evaluation of human conduct (The Philosophy Pages)As used originally by the ancient Greeks, the term "philosophy" meant the pursuit of knowledge for its own sake, and comprised ALL areas of speculative thought, including the arts, sciences and religion.Philosophical questions (unlike those of the sciences) are usually foundational and abstract in nature. Philosophy is done primarily through reflection and does not tend to rely on experiment, although the methods used to study it may be analogous to those used in the study of the natural sciences.In common usage, it sometimes carries the sense of unproductive or frivolous musings, but over the centuries it has produced some of the most important original thought, and its contribution to politics, sociology, mathematics, science and literature has been inestimable. Although the study of philosophy may not yield "the meaning of life, the universe and everything", many philosophers believe that it is important that each of us examines such questions and even that an unexamined life is not worth living. It also provides a good way of learning to think more clearly about a wide range of issues, and its methods of analyzing arguments can be useful in a variety of situations in other areas of life.

Bash ScriptingEverything you need to know about Bash//What's a shell, and why should you care about it?Any recent computer operating system (byrecent, we mean since about 1970) hassome sort of user interface-some way of specifying commands for the operating sys-tem to execute. But in lots of operating systems, that command interface was reallybuilt in and there was only one way to talk to the computer. Furthermore, an operat-ing system's command interface would let you execute commands, but that wasabout all. After all, what else was there to do?The Unix operating system popularized the notion of separating the shell(the part ofthe system that lets you type commands) from everything else: the input/output sys-tem, the scheduler, memory management, and all of the other things the operating system takes care of for you (and that most users don't want to care about). The shell was just one more program; it was a program whose job was executing other pro-grams on behalf of users.But that was the beginning of a revolution. The shell was just another program thatran on Unix, if you didn't like the standard one, you could create your own. So bythe end of Unix's first decade, there were at least two competing shells: the Bourne Shell, sh(which was a descendant of the original Thomson shell), plus the C Shell, csh. By the end of Unix's second decade, there were a few more alternatives: theKorn shell, (ksh), and the first versions of the bash shell (bash).//IntroductionWhat is shell propmt?When does paralysis begin and end?CommandsSimple commandsComplex commandsCompound commandsWhat is shell script?The advantages are found only in bashWhat is interactive chance?Chapter OneCreate and run the Bash programWriting and namingIn which coincidence will the program work?Add commentsChapter IIBash environmentShell initialization filesVariables in BashTypes of variablesClassify variables based on their contentCreate variablesExport variablesThe difference between * $ and @ $Recycle shell programs using variablesQuote characters in BashUtility quote typefacesCharacter escapeSingle quotation marksDouble quotation marksLocalesExpansions in BashExpanded swastika {}Length Expansion ( )Substitution of commandsComputational expansionProcess substitutionExpands file namesAlternative commands in BashUtility alternative commandsCreate and delete alternate commandsFaster functionsChapter IIIStereotypes in BashRegular ExpressionsThe difference between basic and extended stereotypesGrep commandGrep command and typical expressionsAxes of lines and wordsCharacter TypesWildcardsMatch patterns using Bash featuresCharacter RangesChapter IVConditional structures in BashExpressions used with ifThe commands that follow are thenScan filesCheck the chance optionsSimple applications on the if statementText comparisonsIf / then / else is builtThe difference between [] and [[]]Examine the command line argumentsThe names of files that contain spacesNested if statementsLogical operationsUse the exit statement with ifChapter VRepetitive tasks in BashEpisode for in BashHow to make a loop for iterativeExamplesBasename commandWhile loop in BashHow to make a while loopWhile nested loopsCalculate the averageUntil loop in BashHow to make a loop untilThe Break and Continue commandsBreak commandContinue commandChapter VIFunctions in BashWhat are functions?Functions SyntaxPosition coefficients in functionsDisplaying FunctionsRecyclingAdjust the pathunset pathmungeChapter VIIWriting interactive Bash programsView user messages in BashInteractive or non-interactive programs?Use the echo commandGet user input in BashUse the read commandRequest user inputRedirection and file descriptorsRedirect erro

Iron muskthe iron man who changed the worldThe real story of Elon Musk, the man who changed the worldHe has been called the real life Tony Stark, he's worth $12.5 billion, he has been labelled the world's 38th most powerful person and he has world leaders on speed dial.The 45-year-old changed the way you shop, and now he's working on the way you get there. When he's done he wants to power our home, fire us like bullets through tubes that link cities and then take us all to Mars. Apart from that, he lives a pretty chill life.The legend of Elon Musk has now gone further than the mighty Apple and he has become a cult all of his own.It's a tale of one man moving mountains. It is also a tale punctuated by massive, near reckless gambling of a fortune that he built from nothing on insane concepts that sound like drunk bar talk-----------------Sleeping in the office and showering at the local YMCA, he built Zip2, essentially city guide software for newspapers, with his brother, and sold it to Compaq for more than $300 million in February 1999. He was 28 and reportedly pocketed $22 million. It was the ideal time to ride off on a thoroughbred horse and live off the interest on a big yacht.He didn't do that. Instead he ploughed all that money into an 11.7% stake in PayPal, which translated into a $160 million fortune when the payments company sold out to eBay for $1.5 billion in 2002.Musk just about made time to marry Justine Wilson and they overcame the death of their first child, Nevada, at just 10 weeks old, to have five children together. Wilson reportedly never forgot the way Musk refused to grieve Nevada's death, even though they went on to have five children together.The two battled on for eight years together, but six weeks after their divorce he was seen with Inception star Talulah Riley. He married her in 2010, they divorced in 2012, remarried in 2013, almost divorced in 2014 and then finally Riley filed a massive suit in March 2016. They gave it a good try...

GitThe Ultimate Beginner's Guide to Learn Git Step by StepGit is an Open Source Distributed Version Control System. Now that's a lot of words to define Git.Let me break it down and explain the wording: - Control System: This basically means that Git is a content tracker. So Git can be used to store content - it is mostly used to store code due to the other features it provides.- Version Control System: The code which is stored in Git keeps changing as more code is added. Also, many developers can add code in parallel. So Version Control System helps in handling this by maintaining a history of what changes have happened. Also, Git provides features like branches and merges, which I will be covering later.- Distributed Version Control System: Git has a remote repository which is stored in a server and a local repository which is stored in the computer of each developer. This means that the code is not just stored in a central server, but the full copy of the code is present in all the developers' computers. Git is a Distributed Version Control System since the code is present in every developer's computer. I will explain the concept of remote and local repositories later in this article.Why a Version Control System like Git is neededReal life projects generally have multiple developers working in parallel. So a version control system like Git is needed to ensure there are no code conflicts between the developers.Additionally, the requirements in such projects change often. So a version control system allows developers to revert and go back to an older version of the code.Finally, sometimes several projects which are being run in parallel involve the same codebase. In such a case, the concept of branching in Git is very important.

React jsThe Complete Beginner's Guide to React - 2nd Edition (2020)Facebook's React has changed the way we think about web applications and user interface development. Due to its design, you can use it beyond web. A feature known as the Virtual DOM enables this.In this chapter we'll go through some of the basic ideas behind the library so you understand React a little better before moving on.What is React?React is a JavaScript library that forces you to think in terms of components. This model of thinking fits user interfaces well. Depending on your background it might feel alien at first. You will have to think very carefully about the concept of state and where it belongs.Because state management is a difficult problem, a variety of solutions have appeared. In this book, we'll start by managing state ourselves and then push it to a Flux implementation known as Alt. There are also implementations available for several other alternatives, such as Redux, MobX, and Cerebral.React is pragmatic in the sense that it contains a set of escape hatches. If the React model doesn't work for you, it is still possible to revert back to something lower level. For instance, there are hooks that can be used to wrap older logic that relies on the DOM. This breaks the abstraction and ties your code to a specific environment, but sometimes that's the pragmatic thing to do.One of the fundamental problems of programming is how to deal with state. Suppose you are developing a user interface and want to show the same data in multiple places. How do you make sure the data is consistent?Historically we have mixed the concerns of the DOM and state and tried to manage it there. React solves this problem in a different way. It introduced the concept of the Virtual DOM to the masses.Virtual DOM exists on top of the actual DOM, or some other render target. It solves the state manipulation problem in its own way. Whenever changes are made to it, it figures out the best way to batch the changes to the underlying DOM structure. It is able to propagate changes across its virtual tree as in the image above.Virtual DOM PerformanceHandling the DOM manipulation this way can lead to increased performance. Manipulating the DOM by hand tends to be inefficient and is hard to optimize. By leaving the problem of DOM manipulation to a good implementation, you can save a lot of time and effort.React allows you to tune performance further by implementing hooks to adjust the way the virtual tree is updated. Though this is often an optional step.The biggest cost of Virtual DOM is that the implementation makes React quite big. You can expect the bundle sizes of small applications to be around 150-200 kB minified, React included. gzipping will help, but it's still big.

A balance of flexible and inflexible qualities make Haskell a fascinating programming language to learn and use.First, the Haskell programming language is not named after Eddie Haskell, the sneaky double-dealing neighbor kid in the ancient TV sitcom, Leave It To Beaver.Haskell is named after Haskell Brooks Curry, an American mathematician and logician. If you don't know, logicians create models to describe and define human reasoning, for example, problems in mathematics, computer science, and philosophy. Haskell's main work was in combinatory logic, a notation designed to eliminate the need for variables in mathematical logic. Combinatory logic captures many key features of computation and, as a result, is useful in computer science. Haskell has three programming languages named after him: Haskell, Brooks, and Curry.Haskell the language is built around functions, useful blocks of code that do specific tasks. They are called and used only when needed.Another interesting feature of functional languages like Haskell: functions are treated as values like integers (numbers) and strings. You can add a function to another function the way you can add an integer to an integer, 1 + 1 or 35 + 53. Perhaps the best way to describe this quality is a spreadsheet: in a cell in the spreadsheet, you can add numbers as well as a combination of functions to work on numbers. For example, you might specify each number in cells 1-10 be added up as a sum. In Excel, at least, you also can use SUMIF to look for a pattern in cells 1-10 and, if the pattern is found, perform an action on any cells with the pattern.What Makes Haskell Special?Technically, Haskell is a general-purpose functional programming language with non-strict semantics and strong static typing. The primary control construct is the function. (Say that fast ten times!) Here's what it means: - Every language has a strategy to evaluate when to process the input arguments used in a call to a function. The simplest strategy is to evaluate the input arguments passed then run the function with the arguments. Non-strict semantics means the input arguments are not evaluated unless the arguments passed into the function are used to evaluate what is in the body of the function.- Programming languages have rules to assign properties - called a type - to the components of the language: variables, functions, expressions, and modules. A type is a general description of possible values the variable, function, expression, or module can store. Typing helps minimize bugs, for example, when a calculation uses a string ("house" or "cat") instead of a number (2 or 3). Strong static typing evaluates the code before runtime, when the code is static and possibly as code is written.- The order in which statements, instructions and functions are evaluated and executed determines the results of any piece of code. Control constructs define the order of evaluation. Constructs use an initial keyword to flag the type of control structure used. Initial keywords might be "if" or "do" or "loop" while final keywords might be "end if" or "enddo" or "end loop". Instead of a final keyword, Haskell uses indentation level (tabs) or curly brackets, or a mix, to indicate the end of a control structure.Perhaps what makes Haskell special is how coders have to think when they use the language. Functional programming languages work in very different ways than imperative languages where the coder manages many low-level details of what happens in their code and when. While it is true all languages have things in common, it's also true languages are mostly functional or mostly imperative, the way people are mostly right handed or left handed. Except functional programming languages require a different way of thinking about software as you code.

Obedient servantMasochism was the term initially used by the famed Austrian psychiatrist Richard Von Krafft-Ebing, author of the classic text, Psychopathia Sexualis (1931). Krafft-Ebing named masochism after the Austrian writer Leopold Von Sacher-Masoch, whose books often carried a masochistic theme. Sacher-Masoch also practiced what he preached. He was attracted to dominant women in furs as depicted in his book, Venus in Furs (1869). Apparently, the writer pressured his first wife Aurora Von Rümelin to live out the experiences of his book which she did, but with reservations. Following his death, she wrote about her experiences in her memoir, My Life Confession (Mein Lebensbeichte) (1906). Bored with marriage, Sacher-Masoch also had mistresses who engaged in his sexual fantasies. For example, he signed a contract with Baroness Fanny Pistor to make him her slave for 6-months provided she wear furs as often as possible, particularly when she was in a vile mood.According to the DSM-V (2013), the paraphilic focus of sexual masochism involves the act of experiencing-over a period of at least 6 months-sexual arousal from being humiliated, beaten, bound, or made to suffer in some way. To be considered problematic, the fantasies, urges, or behaviors must cause significant distress or impairment in social, occupational, or other important areas. Some scholars differentiate between sexual masochism and moral masochism-moral masochism has more to do with self-punishment for bad behavior; sexual masochism-which this article is primarily concerned with-has to do with sexual arousal leading to sexual satisfaction (Kernberg, 1991; Maleson, 1984).Sexual masochistic behaviors vary depending on an individual's preference. For example, some masochists like to be tied up and flogged (BDSM); others prefer to be verbally humiliated only; and some are aroused by more severe or dangerous forms of masochism such as asphyxiation, to name a few. Nevertheless, there are many fallacies about masochism which the following list may help to dispel:1. Most masochists have their limits and safety is extremely important. The research has indicated that relatively few people get hurt, and when injury does occur it's usually the result of an accident or poor judgment (Moser & Levitt, 1987; Scott, 1983).2. According to Money & Lamacz (1989), if under control, a sadist and a masochist can make a sexuality compatible match.3. Masochists tend to be upper-middle class.4. Masochists tend to be well-educated.5. Studies have found that masochists are not anti-feminist (Cross & Matheson, 2006).6. More men engage in masochistic behavior than do women. The main differences have to do with the specific acts preferred. Women prefer less intense forms of masochism usually related to a relationship (e.g., light spanking); men prefer acts that reduce their status as a man (e.g., being forced to kiss a partner's feet or being cuckolded (Baumeister & Butler, 1997).7. There are far more masochists than there are sadists (Baumeister, 1988, 1989; Cross & Matheson, 2006).8. Prostitutes report a more disproportionate ratio. In fact, one of the biggest challenges for a self-respecting masochist is to find a suitably cooperative sadist.9. According to the professional literature, many sadists start out as masochists.10. The onset of masochism was found to be 19.3 years of age, although fantasies have been reported in childhood (DSM-V, 2013).11. Freud (1905/1953) believed that in every sadist there is a masochist and in every masochist there is a sadist. He coined the term sadomasochism.12. Deleuze (1967) rejected the term sadomasochism. He saw sadism and masochism as distinct.13. Both sadist and masochist exert control in the sadomasochistic dynamic. The sadist takes overt control and the masochist prefers it that way.14. Both sadist and masochist share the delight in their sexual process and differ from other sadis.
