Amidst the code's embrace, a dance takes flight, A ballet of tools, radiant in their light. Python, versatile, with libraries wide, Weaves data like threads in a seamless stride. Awk's whispers craft patterns with finesse, Sculpting structures, a dance to impress. Sed's magic transforms, a spellbinding play, As commands entwine in a mystical sway. Grep seeks patterns, a digital quest, A symphony of characters, a treasure chest. Spreadsheets, a canvas where data paints, With sorting and filtering, it deftly acquaints. In text's rich tapestry, their roles unfold, A symphony of tools, a story told. Syntax and style, a harmonious blend, In scripted serenity, they transcend.
In zeroes and ones, the code doth reside And bitwise operators, the tools we use To manipulate each bit and byte with pride And make our programs run without excuse With AND, we set to zero unwanted bits While OR lets us combine them as we please XOR flips the switch, the logic never quits And NOT turns ones to zeroes with great ease The shift operators move bits left or right Multiplying or dividing by powers of two A useful tool in many a coding fight To make our programs faster and more true Oh, bitwise operators, how we adore Thy power to transform and so much more.
Oh, Linux cat, your simple command line grace Makes text files dance and sing with effortless ease In bytes and bits, you weave a spell so chaste That even novices find their worries appeased With just a flick of keystrokes on the screen You summon words from darkness into light No flashy GUI, no bells, no whistles keen Yet all who use you find their hearts alight You are the feline of the digital realm A trusty friend, a helper always near Your purrs and meows, a soothing audio helm For those who navigate the tech frontier Oh, Linux cat, how much we owe to thee For making plain text files a joy to see.
Amidst the code that flows like poetry, A choice is made to bind or let flow free, To define or not, to reign in or set loose, The type that guides each variable's use. Static types, like form and meter in verse, Give structure, clarity, and aid reverse, Errors caught before they can wreak havoc, Code runs smoothly, no need to panic. But some may argue, let dynamism reign, Let freedom ring, let chaos have domain, For creativity needs room to grow, And rigid rules may stifle its flow. So let us weigh the pros and cons, decide, Which type of typing we shall abide, For each has strengths and weaknesses to bear, And in our code, they both have a share.
Amidst the endless expanse of the web, Where information abounds in great measure, A crawler roams, its purpose to probe, And gather data to treasure. Through links and pages it tirelessly roams, Picking up clues with each passing site, No matter how obscure or close to home, It works with an unwavering might. The web crawler scours with a diligent eye, Cataloguing every piece of content, Not swayed by emotion, nor influenced by lies, It remains steadfast in its intent. Oh, web crawler, your work is noble and true, A tireless servant to the data pursued.
Amidst the realm of code, where logic reigns, A power lies in statements of control. A force to guide the program's many veins, And shape its path towards a given goal. The "if" statement, a cornerstone so true, Checks for conditions, true or false its cue. It branches paths, a choice it must pursue, And executes code that aligns with its view. The "for" loop, a structure so divine, Repeats its block a given number of times. Its power lies in its iterative design, Transforming code into efficient rhymes. These statements guide the flow of program's run, Control its fate, until its task is done.
Oh unix, creatures of a different kind, Whose fate was sealed by cruel and ruthless hands, Denied the pleasures of love, and confined To serve as slaves in rich and powerful lands. Your voices, once so rich and deep and strong, Were silenced by the blade that took your pride, Your manhood taken, and your souls were long Tortured, as if you had something to hide. But in your weakness, you found strength to rise, To serve with loyalty and grace and skill, To gain respect and power in their eyes, And prove that you were more than what they'd kill. Oh unix, you may have lost your fleshly crown, But your spirit shines bright, and will never be put down.
Oh CRUD, the basics of database design, Create, read, update, and delete, in tune, The simple actions that we must refine, To manage data, and make it opportune. First, we create, a record to behold, With fields and values, our data is born, Then we can read, the story that's told, To find what we need, and not be forlorn. But data must change, it's the way of life, And so we update, to keep it current, With new information, free from strife, Our records are kept in a state so fervent. Finally, we delete, when it's all done, And the data is no longer required, A clean slate, with room for more to come, A database that's refined and inspired. Oh CRUD, the pillars of database lore, The foundation on which our data will soar.
In modern times, the QWERTY reigns supreme, But alternatives exist for those who seek A better way to type and boost their speed With Dvorak, Colemak, and Workman sleek. Dvorak's design has keys arranged anew, For most used letters in the home row lie, Reducing finger travel, strain, and through Training, typing speed can truly amplify. Colemak improves on Dvorak's foundation, Adding keys like C, V, X, and Z, To where the pinkies rest without vexation, And typing common words becomes a breeze. Workman's blend of QWERTY and new thought, Minimizes same-finger and hand-switching fraught. These three keyboard layouts, unique in style, Offer increased efficiency and smiles.
In realms of data, where knowledge finds its place, There dwells a method, LDA by name, A mighty tool, with latent topics to trace, And themes of books, it seeks to proclaim. With corpus vast, a collection of tomes, It ventures forth to uncover hidden gems, Through words and texts, it nimbly roams, To find the essence of what each book stems. From matrix formed, with documents aligned, LDA unveils the topics, rich and deep, Like threads of thought intricately entwined, Revealing secrets that the texts do keep. Oh, LDA, thou art a wondrous art, Unveiling themes that lie within each part.
