This textbook is intended as a textbook for one-semester, introductory computer science courses aimed at undergraduate students from all disciplines. Self-contained and with no prerequisites, it focuses on elementary knowledge and thinking models. The content has been tested in university classrooms for over six years, and has been used in summer schools to train university and high-school teachers on teaching introductory computer science courses using computational thinking.This book introduces computer science from a computational thinking perspective. In computer science the way of thinking is characterized by three external and eight internal features, including automatic execution, bit-accuracy and abstraction. The book is divided into chapters on logic thinking, algorithmic thinking, systems thinking, and network thinking. It also covers societal impact and responsible computing material – from ICT industry to digital economy, from the wonder of exponentiation to wonder of cyberspace, and from code of conduct to best practices for independent work.The book’s structure encourages active, hands-on learning using the pedagogic tool Bloom's taxonomy to create computational solutions to over 200 problems of varying difficulty. Students solve problems using a combination of thought experiment, programming, and written methods. Only 300 lines of code in total are required to solve most programming problems in this book.
Information technology: general topics, Network hardware, Computer programming / software engineering, Mathematical theory of computation
“The book companion website includes the course’s lecture and project slides as well as Go source code. … Xu and Zhang validate the view that it is indeed more concerned with … CS instruction itself and provides an effective framework for teaching the subject from introductory to advanced courses. Thus they agree with other notable CT researchers and practitioners, such as Denning and Tedre [1], and their textbook is a most valuable contribution to CS education.” (Harry J. Foxwell, Computing Reviews, October 12, 2022)“The book has a companion website from which readers can pull down over 200 MB of zip files with lecture notes, lab notes … and project notes. This is a puzzling book in some respects. On the one hand it covers basic concepts and terminology for the beginning student, yet on the other hand plunges into sophisticated topics without drawing a breadth. Likewise, it claims that programing experience is not a prerequisite … .” (Anthony J. Duben, Computing Reviews, August 30, 2022)“The most preeminent characteristic of this book is its ‘thinking’-perspective, which the reader may or may not like, and which perhaps leads to a suboptimal arrangements of topics. … the material presented is impressive, and at least the fundamentals are covered in great detail.” (Dieter Riebesehl, zbMATH 1490.68001, 2022)

I honestly have no words for this book. I love Michael Jackson and I am one of his biggest fans . Reading this felt like I was having a deep late night conversation with him. I wish I could read it for the first time again!!! I LOVE YOU ALWAYS MICHAEL #FOREVERINNOCENT #MJ #SHAMONE #HEEHEE #DONTSTOPTILLYOUGETENOUGH
Aangetrokke met die eerste oogopslag, maar dis nie gelykpad nie
Liefdesverhale is ’n effektiewe manier om waarhede aangaande verhoudings en die huwelik oor te dra. “… as jy die dag besluit om lief te wees vir die persoon wat jy gekies het, het jy ’n goeie kans om dit te maak werk.” (p. 65) Dit is raad wat ek raaklees in Veral jy, die tweede boek in die reeks oor die Du Bois-susters. Die skrywer is die gewilde Elsa Winckler.
Boek 1, In ’n oomblik, was die storie van die warrelwind romanse tussen Kirsten en Marnus. Boek 2 open met hulle troue en die plofbare ontmoeting tussen ’n volgende van die susters, Martine, en Antonie, een van die strooijonkers. Daar was na hom verwys as die “strooijonker-sonder-naam”, want hulle het nie tyd gemors met uitruil van name nie.
Antonie kom met bagasie wat spruit uit ’n ongelukkige kinderlewe en Martine het self ’n effe verwronge uitkyk oor die wenslikheid van trou. Dus is die tafel gedek vir seerkry. Voeg daarby ’n bitter tante wat ongenooid opdaag, en dinge verloop alles behalwe glad vir hulle.
Hartverskeurende en eerlike reis deur groot verlies
Anderkant die water is ’n boek wat jou bombardeer met emosies. Ronel du Plessis, eggenote van die voormalige Springbokrugbyspeler, Jannie du Plessis, skryf met pynlike eerlikheid oor die ramp wat hulle gesin getref het toe hulle jongste spruit in hulle swembad verdrink het.
Sy begin by die begin van haar en Jannie se verhaal, mediese studente, hulle hospitaaljare, hulle verblyf in Frankryk toe Jannie daar gaan speel het vir ’n Franse klub. Terug in Suid-Afrika, die opwinding van ’n huis teen die berg wat met haar siel praat, maar uiteindelik die plek van groot verlies sou word.
Haar sketse en gedigte gee verdere diepte aan haar vertelling. “My kalender het nou nie meer dae, dit bestaan net uit voor en na” (p.197) en “dalk kan U my vaswerk, ek voel te oop en rou, bring die naald en gare, Heer kom tog, maak net gou.” (p.234) Daar was tye wat sy intens met die Here geworstel het, kwaad was, ontnugter en teleurgesteld, maar haar geloof het staande gebly en haar staande gehou.
Ek sal nie so voorbarig wees om te sê dat ek kan verstaan nie. My eie verliese was nog nie so teen die normale verloop van ouderdom nie. Ek het wel as ‘n pad gestap saam met ’n vriendin wat self ’n dogter moes afstaan, gehelp met troosbedieninge, maar selfs dit gee mens net ’n oppervlakkige verstaan van sulke pyn en verplettering. Anderkant die water help wel om so ’n klein bietjie meer begrip te kry.
The Memories Across Time is a heartfelt novel about family history, traditions & faith.
The Memories Across Time is a heartfelt novel about family history, faith, and the search for identity. Kiril Kristoff weaves the past and present together, inviting readers to consider how the lives and choices of earlier generations can shape the people who come after them.
The story’s exploration of ancestry and heritage gives it emotional depth, while its historical setting brings a wider world to life. At its heart are questions many readers can relate to: Where do we come from? What do we inherit from our families? And what can learning about the past teach us about ourselves?
I recommend this book.

*Going Dutch* is a class of its own. I would like to thank Obie. Rarely have I encountered such an extraordinary book of South Africa (and the Netherlands). It adds a great deal to what I knew. Obie's stories, encounters, photographs, the history of the country and the relationship with the Netherlands — it is all remarkably multifaceted. At times, reading and viewing it was an emotional experience. Hans de Jong - "Platland"/Netherlands.
