-Learning Perl 6
+Math Adventures With Python Webpage: https://nostarch.com/ mathadventures Author: Peter Farrell Price: $29.95 ISBN: 978-1-59327-867-0 On the eighth of January, opensource.com had an interview with an author, and it sounded interesting, so I decided to get the book: https://opensource.com/article/19/1/hacking-math Right off the bat, I liked the author, as in the introduction he already explains why people find maths boring, no outcome! How true, then goes on to explain more. Since python is included with Ubuntu, there is only one download, “processing 3”: https://processing.org/download/ “Processing is a flexible software sketchbook and a language for learning how to code within the context of the visual arts.”

-If you’re ready to get started with Perl 6, ‘Learning Perl 6’ is the book you want, whether you’re a programmer, system administrator, or web hacker. Perl 6 is a new language - a modern reinvention of Perl suitable for almost any task, from short fixes to complete web applications. This hands-on tutorial gets you started.

-I must admit I have seen the screen name on perlmonks.org, but I have no idea who the author is. So much for something about the author, as this is obliviously a pseudonym. https://www.perlmonks.org/index.pl?node_id=385334
-Perl 6 is the next evolution in the Perl ecosystem and I am holding my breath excitedly until it is included in your standard Ubuntu distribution. You can, of course, try it out already. This is why I decided to get this book. There is something about Perl that makes it sexy. I don’t know if it is because perldocs are so much better than awk manpages, or that it is easy to pick up and use.
+Le huit janvier, opensource.com a interviewé l’auteur et le livre avait l’air si intéressant que j’ai décidé de me le procurer : https://opensource.com/article/19/1/hacking-math
-This book is packed chock full of information from the very first page of the introduction. There are exercises for you on every other page. This is a sink or swim book; do not be fooled by the mild mannered cover. The climb is steep with numbers and strings, et-cetera, until chapter 5, where blocks are explained as: ”Block(s) are the thingys that group multiple statements into a single thingy.” This made me smile. Things ease off a bit, and we are led to believe this will go easier. The terms used are what made me read the chapter again, as I am not a programmer, things like phasers have a completely different meaning to me. The thing I respect most about this book is that is not brimming with acronyms. (A pet hate of mine.) Things are explained clearly and concisely. The odd factoids in-between, with little pictures / icons, break you out of your frown. Yes, frown you will... There are lots of examples, which is a plus. There is a whole chapter on errors - when things go wrong - that does a remarkable job explaining those cryptic error messages Perl loves. Something I have never used in Perl is modules, or to be precise, other people’s modules. Chapter 10 will show you how to go about acquiring these modules for your own use. The downloads for the book are actually kept on Github, so the links in the book are not used. Find it all here: https://github.com/briandfoy/LearningPerl6_Downloads
+J’ai apprécié l’auteur tout de suite, car, dans l’introduction, il explique déjà pourquoi des gens trouvent les maths ennuyeuses - aucun dénouement ! C’est vrai, puis il continue en expliquant davantage. Puisque Python est inclus dans Ubuntu, il n’y a qu’un téléchargement à faire, « processing 3 » : https://processing.org/download/
-As this is the very first edition, small errors are to be expected. Reading “Perl6, keeping the easy, hard and impossible in reach” is like balancing on a tightrope. There is so much information here, but it always stops short of information overload. At the end of chapter 21, there are almost another 100 pages covering the answers to the various exercises. (Yes that’s how many exercises there are!).
+« Processing est un logiciel flexible de carnet de croquis et un langage pour apprendre à coder dans le contexte des arts visuels. »
-I will not spoil the book for anyone - woofles dies in the end - but I CAN say you will not regret reading this. You can read some of it online if you make an account at O’Reilly media. I did not do any of the exercises as I am planning on reading it again, this time doing the exercises – I wanted to get a feel for what I was letting myself in for.
+As someone who grew up with logo, the turtle is very familiar, just a pity the ‘turtle’ is now a triangle. Do not let this put you off, you are shown straight away how to change it! Once Peter teaches you how to ‘drive’ your turtle, the exercises start – to make beautiful art with simple maths. The going feels slow in the first three chapters, but you have to realise you are learning multiple things at once and how they slot together. Chapter four, we enter algebra territory and solving equations graphically. Most exciting stuff. It just ramps up from there as we are taught to move the shapes we create. I do not know if I should use the word animation here, I do not want people to get the wrong idea or misrepresent the book, but if you stick to it, this is a most rewarding chapter. I also do not want to give anything away, but there are some cool designs waiting for you. Everything is put out in detail - not just code, but drawings too - and explained, and you are given practical advice at every turn. With “Processing 3” you get immediate results and it feels good to see what was just explained in action. I have recently watched three blue one brown video on sound waves and can now see the maths behind the popular videos. + If you are a fan of that channel, (https://www.youtube.com/channel/UCYO_jab_esuFRV4b17AJtAw/videos) this book is for you.
-My recommendation, for anyone reading this book, is to start at the beginning and not skip a single thing, no matter how well you think you know it.
+Puisque j’ai grandi avec le logo, je connais bien la tortue ; c’est juste dommage que la « tortue » soit maintenant un triangle. Ne vous découragez pas, car on vous montre tout de suite comme le changer ! Une fois que Peter vous aura montré comment « piloter » votre tortue, les exercices démarreront : comment créer de la beauté artistique avec des maths simples.
-The only negative part is the price of the book, $54.82 from Amazon and over $100 locally, which every man in the street can not afford.
+Au cours des trois premiers chapitres, on a une impression de lenteur, mais vous devez réaliser que vous apprenez de multiples choses en même temps et comment elles s'imbriquent. Dans le chapitre quatre, nous entrons dans le territoire de l'algèbre et la solution graphique des équations. C’est vraiment passionnant. Et ça ne fait que commencer : nous apprenons à déplacer les formes que nous créons. Je ne sais pas si le mot animation est approprié ici, car je ne veux pas que les gens arrivent à la mauvaise conclusion ou dénaturent le livre, mais si vous persistez, ce chapitre est des plus gratifiants. Je ne veux rien dévoiler non plus, mais des dessins très sympas vous attendent. Tout est présenté en détail - pas seulement le code, mais les dessins aussi - et expliqué, avec des conseils pratiques à la moindre occasion. Vous avez des résultats tout de suite avec « Processing 3 » et vous êtes heureux de voir en action ce qui vient d’être expliqué. J’ai récemment regardé une vidéo 3Blue1Brown sur les ondes sonores et maintenant je reconnais les maths derrière ces vidéos populaires.
-The content of the book:
+Si vous êtes fan de ce canal (https://www.youtube.com/channel/UCYO_jab_esuFRV4b17AJtAw/videos), ce livre vous est destiné.
+Every chapter is just another step up from the previous one and before you realise it, you have reached the Mandelbrot function in chapter 7, mentioned in the introduction. Beautiful fractals await those with patience. Trust me, you will be problem-solving in no time! There are 12 Chapters to look forward to. There is no shortage of information in this book, and at no point are you left frowning at anything. I wish Peter was my teacher at school! You can find Peter at: https://twitter.com/hackingmath - If you have read the interview on opensource.com you will have a good understanding of who the author is. This is one of those books that deserve a place on your bookshelf and some bookmarks. The book deserves all the praise it can get for its great explanation and non-serious tone to actually convey some rather serious information.
+Chaque chapitre suit le précédent d’un pas de plus et, avant de vous en rendre compte, vous avez atteint dans le chapitre 7 la fonction Mandelbrot mentionnée dans l’introduction. De très belles fractales attendent ceux qui sont patients. Faites-moi confiance : vous serez très vite en train de résoudre des problèmes ! Il y a 12 chapitres que vous voudrez atteindre rapidement. Ce livre ne manque pas d’informations et à aucun moment vous ne froncerez les sourcils sur quoi que ce soit. J’aurais voulu avoir Peter comme enseignant à l’école !
+Vous pouvez trouver Peter sur https://twitter.com/hackingmath et, si vous avez lu l’entretien sur opensource.com, vous aurez une bonne idée de l’auteur.
+Ce livre est l’un de ceux qui méritent de figurer sur votre étagère, avec quelques marque-pages. Le livre mérite amplement toutes les louanges pour ses explications magnifiques et le ton léger utilisé pour transmettre des informations assez sérieuses.
