Using Perl Chr() and Ord() Functions
Using Perl Chr() and Ord() Functions The Perl programming languagesà chr() and ord() functions are used to convert characters into their ASCII or Unicode values and vice versa. Chr() takes an ASCII or Unicode value and returns the equivalent character, and ord() performs the reverse operation by converting a character to its numericà value.à Perl Chr() Function The chr() function returns the character represented by the number specified. For example: #!/usr/bin/perl print chr (33) print /n; print chr (36) print /n; print chr (46) print /n; When this code is executed, it produces this result: ! $ Note: The characters from 128 to 255à are by default not encoded as UTF-8 for backward compatibility reasons. Perls Ord() Function The ord() function does the opposite. It takes a character and converts it into its ASCII or Unicode numeric value. #!/usr/bin/perl print ord (A); print /n; print ordà (a); print /n; print ordà (B); print /n; When executed, this returns: 65 97 66 You can confirm the results are accurateà by checking an ASCII Code Lookup Table online. About Perl Perl was created in the mid-80s, so it was a mature programming language long before websites exploded in popularity. Perlà was originally designed for text processing, and it is compatible with HTML and other markup languages, so it quickly became popular with website developers. Perls strength lies in its ability to interact with its environment and its cross-platform compatibility. It can easily open and manipulate many files within the same program.

Alfred, Lord Tennyson Poems
Alfred, Lord Tennyson Poems The poet laureate of Great Britain and Ireland, Tennyson developed his talent as a poet at Trinity College, when he was befriended by Arthur Hallam and members of the Apostles literary club. When his friend Hallam died suddenly at the age of 24, Tennyson wrote one of his longest and most moving poems In Memoriam. That poem became a favorite of Queen Victorias.à Here are some of Tennysons best-known poems, with an excerpt from each one.à The Charge of the Light Brigade Perhaps Tennysons most famous poem, The Charge of the Light Brigade contains the quotable line Rage, rage against the dying of the light. It tells the historical story of the Battle of Balaclava during the Crimean War, where the British Light Brigade suffered heavy casualties.The poem begins: Half a league, half a league,Half a league onward,All in the valley of DeathRode the six hundred. In Memoriam Written as a eulogy of sorts for his great friend Arthur Hallam, this moving poem has become a staple of memorial services. The famous line Nature, red in tooth and claw, makes its first appearance in this poem, which begins: Strong Son of God, immortal Love,Whom we, that have not seen thy face,By faith, and faith alone, embrace,Believing where we cannot prove A Farewell Many of Tennysons works are focused on death; in this poem, he ponders how everyone dies, but nature will continue after were gone. Flow down, cold rivulet, to the seaThy tribute wave deliver:No more by thee my steps shall beFor ever and for ever Break, Break, Break This is another Tennyson poem where the narrator is struggling to express his grief about a lost friend. The waves break relentlessly on the beach, reminding the narrator that time moves on. Break, break, break,On thy cold gray stones, O Sea!And I would that my tongue could utterThe thoughts that arise in me. Crossing the Bar This 1889 poem uses the analogy of the sea and the sand to represent death. Its said that Tennyson requested this poem be included as the final entry in any collections of his work after his death.à Sunset and evening star,And one clear call for me!And may there be no moaning of the bar,When I put out to sea, Now Sleeps the Crimson Petal This Tennyson sonnet is so lyrical that many songwriters have tried to put it to music. It ponders, through the use of natural metaphors (flowers, stars, fireflies) what it means to remember someone.à Now sleeps the crimson petal, now the white;Nor waves the cypress in the palace walk;Nor winks the gold fin in the porphyry font:The fire-fly wakens: waken thou with me. The Lady of Shalott Based on an Arthurian legend, this poem tells the story of a lady who is under a mysterious curse. Heres an excerpt: On either side the river lieLong fields of barley and of rye,That clothe the wold and meet the sky;And throââ¬â¢ the field the road runs by The Splendour Falls on Castle Walls This rhyming, lyrical poem is a somber reflection on how one is remembered. After hearing a bugle call echo around a valley, the narrator considers the echoes that people leave behind. à The splendor falls on castle wallsAnd snowy summits old in story;The long light shakes across the lakes,And the wild cataract leaps in glory. Ulysses Tennysons interpretation of the mythological Greek king finds him wanting to return to traveling, even after many years away from home. This poem contains the famous and oft-quoted lineà To strive, to seek, to find, and not to yield. Here is the opening to Tennysons Ulysses. It little profits that an idle king,By this still hearth, among these barren crags,Matchââ¬â¢d with an aged wife, I mete and doleUnequal laws unto a savage race

Product Quality Testing Essay Example | Topics and Well Written Essays - 1500 words
Product Quality Testing - Essay Example The big question here is how much testing needs to be done, because the testing requires time, which is precious because the clients and users want the product as soon as possible. The paper will include sources that will be used in order to support the question of how much testing needs to be done in order to ensure a good quality product and to show that there is a problem when too much or too little testing is done. A review of literature will be presented to show how we come up with the conclusion. The review includes the study done by Rothman (2001) on release criteria. Rothman (2001) tackles when to release a software/ Also in the article written by Barbara Tallent (2008) she discusses when it is enough for testing and releases it in market. At the end of the paper a conclusion was given and the paper will try to find the best answer on the addressed question. In the article written by Johanna Rothman (2001) "Release Criteria: Defining the Rules of the Product Release Game," he discusses the problems involve in releasing the product early. He also point out that the decision of releasing the product comes from the higher authority of the organization usually the production managers. The article includes the case of Rita who heads the team in developing software. The production manager is being pressured by the customers and needs to release the product as soon as possible. In order to do so Rita and PM releases criteria for the team to decide. The criterion includes; All code must compile and build for all platforms Zero high priority bugs For all open bugs, documentation in release notes with workarounds All planned QA tests run, at least 90 percent pass. Number of open defects decreasing for the last three weeks. Feature x unit tested by developers, system tested by QA, verified with customers A, B before release. All open defects evaluated by cross-functional team. The decision in releasing the product at earlier time should comply with the release criteria. The release criteria objectives are specific, measurable, attainable, relevant, and trackable. Before releasing the product it should agreed upon by the entire project team and understood by senior management. The reasons for such release should be reasonable enough. Rothman (2001) in the article uses the release criteria to evaluate whether the product can be release or not. This also assesses the entire project and the prediction of an early warning on the incoming problem on the product. Based on the article a product can be released as long as it complies with the release criteria created by the team. Another review on the immature release of the product is shown in the article written by Bernadette Tallent (2008). In this article she presented a case study wherein the VP of marketing for a software company was about to release a new product. The product was incomplete and the team knows it. Extensive user testing on the product has been done and they concluded that the product was missing several key features. Meetings have been done to assess whether or not to release the product in the market. In order to decide in releasing or not releasing the product the group listed trade offs: Reasons to Release The product was stable The product was due to be announced at an Internet World - if we missed the release date we would miss the

To what age should parents support children Research Paper
To what age should parents support children - Research Paper Example In order to effectively deal with the aim of the study stated above, a research question will be asked and effectively interrogated through data collection procedures. The research question and its sub questions are presented below. From a more academic perspective, there continues to be discussions and debates on the place of law on termination age. That is, the academic relevance of the study has to do with the legal implications for parents in supporting or taking care of their children. This means that there are two general themes or aspects of the research problem that the current study seeks to unify. The first theme forms of the basis of academic discussion where the important place of parenting in the development of children is emphasised. On this theme of the research problem, Buehler et al. (2014) noted that as social beings, all children are born in to a social setup, where they are expected to be nurtured and brought up in a way that can be considered as consolidating with acceptable social standards. Meanwhile, as parents assume parenthood, they are legally obliged as the people responsible for giving children the necessary social guideline into becoming responsible adults. Whiles doing this, there are different roles that parents play for their children, including financial support, emotional support, social support, moral support, and educational nurturing (Cohen & Wills, 2005). However, it has often been the case that some parents have out of ignorance and in some cases, deliberate intentions disregarded their roles to children, causing children to be stranded and frustrated in the course of their natural development (Buehler & Welsh, 2009). With this problem reported in sections public media, it has become an area of concern to legitimise an age to which all parents of sound mind will be expected to support their children to.

Animal Farm and The Russian Revolution Minor characters and events of the novel Animal Farm symbolize things that are related to the history of Russia. Animal Farm is a story on Stalinism and the Russian Revolution. The characters in Animal Farm all have a part in the Soviet Union meaning the Russian Revolution. The similarities of Mr. Jones and Czar Nicholas II, the leader previous to Stalin tie into each other. There was a strike wave go on in Petrograd. Over 300,000 people went through economic crisis. Factories had a lack of fuel and there were power cuts. The railways were collapsing and there was no meat, and a shortage of flour. Hunger spread through the country. The bourgeois liberals of the ââ¬Å"Progressive Blocâ⬠pleaded with Tsar Nicholas for reform trying to frighten him with revolution. That revolution broke into the February Revolution. Farmer Jones came home drunk one night and didnââ¬â¢t feed the animals making it worse than it already was as they were already starving. The animals got the image of the revolution from Old Major in their heads and attacked. They succeeded and won the battle against Mr. Jones as they drove him off the farm. The animals were now free to do what ever they wanted and needed to pick a leader. Out of all of the animals the pigs were considered to be the most brilliant. The two pigs that stood out the most were Napoleon and Snowball. Napoleon is not a good speaker, but he can assert himself. Snowball is a better speaker because he has a lot of ideas. These two pigs did not get along, much like Joseph Stalin and Leon Trotsky. The Russian leaders fought for power and Stalin achieved sole power and Trotsky was exiled. Trotsky escaped Stalinââ¬â¢s dilemmas. Stalin hated his opponent so much that he caused his name to be written simply ââ¬Å"Judas Trotsky.â⬠Stalin stole many of Trotskyââ¬â¢s ideas and methods. Eventually Trotsky was expelled from Russia. In the same manner, Snowball and Napoleon always argued over ideas. Napoleon was already power hungry and had a plan to get rid of Snowball after the rebellion. In the middle of this all, Snowball was planning out to build a windmill for power to energize the farm. Napoleon then directed the dogs he raised since they were puppies on Snowball and chased him off the farm. Napoleon eliminated his only enemy and was free to control the farm.

Pyramus and Thisbe Essay
A first-time encounter with the tale of Pyramus and Thisbe would already send your heart fluttering with a hundred different emotions headed primarily of a loverââ¬â¢s longing for his/her partnerââ¬â¢s touch and the level of passion the two had shown. Pyramus and Thisbe were childhood lovers that carried with them an ill-fated love story when they were forbidden by their parents to be together. Fortunately, the love between our two lovebirds had been so strong that they discovered a way on how they could communicate day and night. A common crack in their walls allowed this to happen, and being neighbors, they were able to keep in touch with one another and exchange sweet thoughts. Until the day when they canââ¬â¢t bear the silent distance between them anymore came, they finally decided to run away from home and so, they had set up to meet under a mulberry tree near Ninusââ¬â¢ tomb. Come nighttime, Thisbee, who arrived first, spotted a fierce lioness and immediately ran for her life. While on escape, she accidently dropped her cloak which the lioness viciously tore into pieces. Pyramus arrived at the scene with the sight of Thisbeââ¬â¢s cloak and abruptly concluded that his better half had died already. With this thought in mind, he took his own life, thinking that he canââ¬â¢t live with the fact that he had left the love of his life to wait alone in the woods. Thisbe arrived minutes later and upon seeing her loverââ¬â¢s dying state, she decided that she would not let death separate them and she took her own life too. The theme of this love story would probably be unconditional love that was unimaginable given Pyramus and Thisbeââ¬â¢s circumstances. Even death was not powerful enough to separate the two ill-fated lovers. I believe the story only shows how there may be hope for everything. They believed in the love they had and even took the risky choice of leaving everything behind even their own families. This part of the book was really to be well-commended. The love stories were enjoyable to read and Edith Hamilton told the stories in a manner where you can completely visualize scene after scene and really added color to oneââ¬â¢s imagination. The narrations were easy to follow and her choice of language was not profane at all, but rather neat and blithe.
