Your future is bright, your future needs coding. Welcome to Coding Your Future: the guidebook that will help you to design, build, test and code your future in computing at www.cdyf.me. Also available as a free ebook and pdf (see section 0.7), this guide is aimed at ALL students in higher education. While this guide supports teaching and learning at the University of Manchester, it doesn’t actually matter:

• where in the world you are studying
• what stage of your degree you are at, from first year through to final year
• what level you are studying at, high school, foundation, undergraduate or postgraduate
• what institution you are studying at, this book is institutionally agnostic
• what subject you are studying, as long as you are computationally curious

There is something in this guidebook for any student of computing, both those inside and outside of Computer Science departments. 👨🏿‍💻👨‍💻👩🏽‍💻👩‍💻👩🏿‍💻

A lot of careers advice can be dry, dull, textbooky, generic and boring with few illustrations and conversations. In the novel Alice’s Adventures in Wonderland shown in figure 0.1, the protagonist Alice wonders why her sister is reading a book without pictures.

Pictures can tell stories, pictures can explain. Pictures can help you understand. Pictures can help you imagine. Pictures can help you code. (Guo 2013) So this book uses pictures (and conversations) to help you imagine and code your future. Other key differences between this and other guidebooks are outlined in section 1.12.

This guidebook will help you develop stronger habits of mind, body and soul using five key ingredients: C, D, Y, F and .me:

1. C is for CODE: Instructions, algorithms, recipes, methods and strategies contained in this guidebook. This code is for your consumption, not for a machine.
2. D is for DATA: From big data to microdata, from your data to my data and our data to metadata. From structured data, to semi-structured data and un-structured data. To factual, statistical, graphical, to readable and audible data. Data bytes, bits and bobs collected together for your analysis and amusement
3. Y is for YOU: This book is all about you, with activities and other coding challenges for you to do in addition to just passively reading
4. F is for FUTURES: Possible futures for you to think about. Try not to dwell on the past. Think about the future. Think about your future.
5. .me is for ME: Hello, my name is Duncan, see figure 0.2. I’m your tour guide here. If you’re feeling a bit lost, follow me and together we can starting coding your future.

Coding Your Future explores techniques for investigating career possibilities, job searching, making career decisions, writing applications and competing successfully in interviews and the workplace.

Alongside these practical engineering issues, this guidebook also encourages you to Design Your Future by taking a step back and reflecting on the bigger picture. You will apply computational thinking techniques, to reflect on who you are, what your story is, how you communicate with other people about your experience, skills and knowledge. As there is a computational theme, you will also need to reflect on what your inputs and outputs (I/O) are, both now and in the future. You’ll also need to think about what recipes (or algorithms) you might start experimenting with

This guidebook investigates professional and pastoral issues in computing, for those with and without Computer Science degrees in the early stage of their careers.

## 0.3 What you won’t learn

This guidebook will NOT teach you how to write code, there’s already lots of fantastic resources to help you do that. We discuss some of them in chapter 7 on computing your future.

So what will you learn from this guidebook? After reading this guidebook, watching the videos and doing the exercises you will be able to:

1. Improve your self-awareness by describing who you are, what motivates you and your strengths and weaknesses
2. Experiment with using some job search strategies and make adjustments to your algorithms as necessary
3. Identify employers, sectors and roles that are of interest to you
4. Improve your written communication skills both for job applications and communicating with other people
5. Plan and prepare competitive written applications using standard techniques including CVs, covering letters, application forms and digital profiles
6. Compete confidently and successfully in interviews. Anticipate and prepare for both technical and non-technical questions
7. Plan further possibilities in your career such as promotion, postgraduate study & research, alternative employment and longer term goals
8. Search and navigate a large “wordbase” (this guidebook and the work it cites). A wordbase is like a codebase, only written predominantly in natural language.

As the title of this guidebook implies, there is a computational flavour here, but you do not have to be studying Computer Science to benefit. There are two main target audiences for this guidebook:

1. Undergraduate and postgraduate students studying Computer Science as a major or minor part of their degree. This includes software engineering, artificial intelligence, human-computer interaction (HCI), information systems, health informatics, data science, gaming, cybersecurity and all the other myriad flavours of Computer Science
2. Undergraduate and postgraduate students studying any subject, with little or no Computer Science at all. You are curious to know about what role computing could play in your future career because computing is too important to be left to Computer Scientists, see chapter 7 on Computing your Future
3. Unless you are a mature student, you are most probably a member of Generation Z

So the prerequisites for this book are that you are studying (or have studied) at a University where English is one of the main spoken languages. You may have some experience already, either casual, voluntary or otherwise, but this book does not assume that you have already been employed in some capacity.

Reading this book from cover to cover like a novel is not recommended. That would be foolish.

“You don’t READ books, you GUT them!”
— William Woodruff

So, gut this book like the fish in figure 0.3. Identify the chapters that are most useful to you (the flesh), and skip the rest (the guts). Which chapters are flesh and which are guts will depend on what stage of the journey you are at. This guidebook is designed to be as “guttable” as possible. To aid gutting, the version published at cdyf.me has a built in search and tables of contents. Before you can gut the fish, you’ll need an anatomical map shown in figure 0.4.

Your future is split into five parts, each of which has several chapters:

1. Chapters 1 to 7 investigate DESIGNING your future
2. Chapters 8 to 13 investigate TESTING your future
3. Chapters 15 to 17 investigate BUILDING your future
4. Chapters 18 to 20 investigate DEPLOYING your future
5. Chapters 21 to 40 investigate CODING your future, by meeting students who are doing just that followed by the final chapter on Reading Your Future

Although presented in a linear order, follow whatever squiggly path suits you best, as shown on the right hand side of figure 0.4. Many students start with chapter 8, but individual entry and exit points to your future will differ.

Let’s look in a bit more detail at each of the five parts of your future, starting with designing your future.

The first six chapters of this guidebook look at what engineers call design. When you build anything, a bridge, a piece of software, a car or a plane you’ll need to do some design like the blueprint in figure 0.5

Building a career isn’t that different to building anything else, you’ll need do many iterations of designing, coding, testing, building and deploying. Designing things often involves answering tricky questions. So when you’re designing your future you’ll need to cover the following:

• Chapter 1: Rebooting Your Future discusses why you should bother reading this guidebook and coding your future
• Chapter 2: Exploring Your Future challenges you to reflect on who you are, what makes you unique and what you have to offer to build better self-awareness
• Chapter 3: Nurturing Your Future looks at ways you to be more concious of, and improve, both your mental and physical health
• Chapter 4: Writing Your Future explores your softer communication skills, how they complement your hard skills and why employers value them so much
• Chapter 5: Experiencing Your Future asks you to reflect on your experience and help identify where you can improve it
• Chapter 6: Choosing Your Future encourages you to broaden your computational horizons. What possibile routes can you choose from, beyond the obvious well-trodden paths?
• Chapter 7: Computing Your Future looks at the role computing can play in your career, especially if Computer Science is not a major part of your degree

The next seven chapters look at testing your future, by taking a test-driven approach to career development. What tests do you need to prepare for and pass before you can starting building your future? Just like building high quality software requires that you pass tests, so too, building a career means passing a series of tests. Each of these tests have inputs, an algorithm and outputs:

• Chapter 8: Debugging Your Future looks at debugging your own written communication such as CVs, résumés, covering letters, application forms and digital portfolios.
• Chapter 9: Hacking Your Future invites you to put yourself in the employers shoes by debugging and hacking other people’s CVs
• Chapter 10: Verbalising Your Future gets you to debug your CV by reflecting on your actions and their impact by articulating them using carefully chosen verbs on your job applications
• Chapter 11: Finding Your Future looks at where and how can you look for interesting opportunities
• Chapter 12: Moving Your Future investigates three of the most important criteria of your job search: location, location, location.

The next seven chapters look at building your future. You’ve passed all the tests, what do do you need to do to keep building your future in the same way as you would build a bridge, like the one shown in figure 0.6.

Once you’ve started to answer the design questions in the first part, you can start to implement it, by testing and building your career:

• Chapter 15: Organising Your Future investigates how to schedule and organise the activities in this guidebook
• Chapter 16: Researching Your Future investigates if a Masters degree or a PhD right for you?
• Chapter 17: Enjoying Your Future is a musical interlude, providing a soundtrack that might help with your wellbeing

The fourth part of this book, looks at deployment issues that follow from the design, build and test phases above. You’ll need good deployment strategies to help with the inevitable stresses and strains of building your future as shown in 0.7

• Chapter 18: Starting Your Future looks at the moves you make after landing your first job. During your transition, how will you start to survive and thrive outside (and after) University
• Chapter 19: Achieving Your Future looks at evidence you can collect of your learning and development using various kinds of certifiable evidence
• Chapter 20: Ruling Your Future provides Ten Simple Rules for Coding your Future, this book in a nutshell

### 0.5.5 Future Coders

The fifth and final part of this guidebook, from chapter 21 onwards meets students who are Coding Their Future and asks them, how did they get to where they are and where are they going next? These chapters form part of a podcast which accompanies this book: Hearing Your Future, see figure 0.8.

The final chapter 40 of the section and book: Reading Your Future lists everything cited in this guidebook.

This guidebook aims to help you build a bridge from where you are now to where you’d like to be in the future. Each chapter of the book contains the following recurring themes:

1. Learning your future: What you will learn from any given chapter
2. Watching your future: videos and animations for you to watch
3. Listening to your future: audio and podcasts for you to listen to
4. Speaking your future: articulating from a script or by improvisation, particularly when preparing for interviews
5. Discussing your future: breakpoints invite you to pause execution of your code and think about your variables and parameters. Can they be improved? Reflect and discuss.
6. Reading your future: because reading is good for your mind, body and soul. Read The Friendly Manual. RTFM. Read THIS Friendly Manual.
7. Writing your future and rewriting your future: written exercises using natural language
8. Quizzing your future: quick quizzes to be done in real-time live scheduled sessions described in chapter 15 (synchronously) and in your own time (asynchronously)
9. Assessing your future: activities to be assessed by yourself, your peers, an employer or an academic (depending on who and where you are)
10. Challenging your future: coding challenges are designed to take you out of your comfort zone by encouraging you to experiment with your thoughts, discussions and actions
11. Signposting your future: the most useful resources that I recommend you read, listen to or watch

## 0.8 Contributing to Your Future

If you’d like to contribute this guidebook, I welcome constructive feedback from loyal opposition and critical friends, see figure 0.10. All contributions will be gratefully acknowledged in section 0.9 unless you ask for your contributions to remain anonymous. If you’re about to graduate or have already graduated in Computer Science, see section 21.21.

If you find what you’re reading here useful and you think other people might benefit too, I’d really appreciate some stars (likes) on the guidebook’s repository at github.com/dullhunk/cdyf to help other people find us. ⭐️🤩⭐️🤩⭐️

I’m looking for feedback and contributions on everything in this guidebook from the small things like typos, grammatical errors and spelling mistakes through to bigger issues for each chapter such as:

• Does the chapter make sense? How could concepts be made more clear?
• Does it strike the right tone, is it pitched at the right level? Not patronising? Too many platitudes?
• Are there too many motivational (or demotivational) quotations?
• Where is it too long and waffly (see figure 8.20) or too short?
• Are there too many (or too few) pictures? What needs more illustration?
• Is it well scoped? Too broad or too narrow?
• Are the stated learning objectives met by the chapter?
• Are the activities clear? Can students understand why the activities are recommended? What other activities could be added?
• Will it make sense to global readers e.g. will students from America, China and India etc understand the quirks and idioms of English language and culture
• Are there too many metaphors? Mixed metaphors? Awkward analogies? Idiotic idioms? Annoying alliterations?
• Too many citations? Not enough citations? Missed any key citations?
• What else is missing?
• Where are the unstated assumptions? Where is the unconscious bias?
• What are the issues with equality, diversity and inclusion?
• Are there too many musical references or annoying emoji? Please bear in mind I’m trying to be irreverent, light-hearted, not-very-corporate but definitely playful to improve readability 😜
• What else needs to be ruthlessly edited out?

All suggestions welcome! Don’t be shy. There are several ways you can contribute, depending on how comfortable you are with Git:

### 0.8.1 For Github Contributors

If you’re familiar with git and markdown, there are several options if you have a github account (see github.com/join) including:

git clone https://github.com/dullhunk/cdyf.git

Most of the guidebook is generated from RMarkdown, that’s all the *.Rmd files. So markdown files are the only ones you should edit because everything else is generated from them including the *.html, *.tex, *.pdf,*.epub and *.docx files.

### 0.8.2 For Gitlab Contributors

Tell us how we can improve this guidebook and we’ll give you some GitLab.com swag as a token of our eternal gratitude, see figure 0.11. The most actionable and constructive suggestions will get the best swag.

We’d like to know how we can improve your future, specifically:

1. What Went Well (WWW) what have you found the most useful part of the guidebook and/or course at www.cdyf.me and why?
2. Even Better If (EBI) how can we make it better, what is missing? Which bits are boring or unclear? Which bits needlessly replicate better resources that can be found elsewhere? Too long, didn’t read (TL;DR)?
3. Any other business (AOB) other comments or suggestions, e.g. would you buy a printed copy if one was available? How useful are the *.pdf and *.epub versions? How useful is the audio podcast?

• Raising an issue privately on GitLab issues (login required) gitlab.cs.man.ac.uk/duncan.hull/cdyf/-/issues/new, if you check the box: This issue is confidential ..., your issue won’t be seen by anybody except you and me
• Creating an issue publicly on GitHub (login required), get credit for contributing an open source project and build your digital profile with your contributions, see section 0.8.1. Issues and bug reports are just as valuable as code and data.
• Filling in this anonymous login-free form at forms.office.com/e/1U4TCfc8Aa

Send us your feedback by 5pm on Friday 6th September 2024. Besides bagging some swag, we’ll be eternally grateful to you for telling us how to make this guidebook better for other students of computing. 🙏

### 0.8.3 For Everyone Else

If you don’t want to (or can’t) use git and github.com then you can:

Any corrections or suggestions will be gratefully received and noted in the acknowledgements section 0.9, unless you tell me otherwise. I welcome all improvements, big and small.

## 0.9 Acknowledgements

The content of this book is based on hundreds of conversations I have had with undergraduate and graduate students of (mostly) Computer Science, Mathematics, Physics and Engineering, since 2012. It is also based on conversations I’ve had with their employers too.

# Coding Comment

This acknowledgements section is really looooooong because I try to practice what I preach about the importance of expressing gratitude, see section 3.4. It also serves as a live demonstration of a (public) gratitude journal. Expressing gratitude, publicly and privately, is a simple and proven technique for improving your mental health. It will also improve the mental health of the people who you thank, and strengthen the communities that you are part of, see 3.8.

If you want to get to the main content of this book you can skip this and go straight to chapter 1.

### 0.9.1 Thank you students

First and foremost, I would like to thank all the students who have helped with this book, both directly and indirectly see figure 0.12.

So, if you have studied some flavour of Computer Science at the University of Manchester since 2012, there’s a high probability you have contributed to this book. Thank you for having the courage to tell me your stories. Thank you for being ambitious, hard working, talented, fearless, creative, inspirational and listening to me (sometimes). It has been my pleasure and privilege to work with you all.

Figure 0.13: Former Computer Science students Peter Sutton and Lloyd Henning of foxdogstudios.com demonstrate their Robot Chef. Thanks Pete and Lloyd for the all the comedy, inspiration and guest lectures

I’d especially like to thank current and former industrial experience (IE) students who have completed a year in industry as part of their degree as well as those who have done summer internships, either as part of the Master of Engineering (MEng) program or otherwise, particularly (in alphabetical order) Ingy Abdelhalim, Nadine Abdelhalim, Eman Ahsan, Matt Akerman, Asma Alshebli, Sami Alabed, Teodora Balmos, Luke Beamish, Eirik Björnerstedt, Liam Breeze, Jingxuan Chen, Jonathan Cowling, Raluca Cruceru, Petia Davidova, Maximilian Gama, Mihail Ghinea, David Green, Lloyd Henning, Ivaylo Iliev, Cristian Ilin, Călin Ilie, Sneha Kandane, Bozhidar Klouchek, Joshua Langley, Struan McDonough, Milen Orfeev, Jason Ozuzu, Alice Păcuraru, Stanislava Piskyulieva, Carmen Práxedes, Kristina Radinova, Tom Robinson, Amish Shah, Pedro Marques Sousa, Teodora Stoleru, Peter Sutton, Kamil Synak, Boris Vasilev and Brian Yim Tam. In addition, the PASS leaders and facilitators, (PASS2-2021, PASS2-2020, PASS2-2019 etc), UniCSmcr.com, HackSoc, CSSoc and Manchester Ultimate Programming members have all been influential on the content of this book. I’ve learned heaps by manually trawling through thousands of your CVs too, so if you’ve shown me a copy of your CV, thanks! Chapter 8 on Debugging your future (self assessment) and chapter 9 on Hacking your future (peer assessment) are based on the most common bugs (or are they features?) I’ve seen in CVs.

So, thank you students for being studious. 🙏

### 0.9.2 Thank you employers

Thanks to all the organisations who have employed students from the Department of Computer Science as either summer interns, year long placements or graduates. A big chunk of this guidebook documents their experience of employers and their graduate recruitment programs.

Thanks to Niall Beard and Sharif Salah at Google for introducing me to Google’s Technical Writing course in section 4.6.2. Writing is rewriting!

So, thanks employers for employing our students. 🙏

### 0.9.3 Thank you colleagues

I’ve also had significant support from colleagues in the Department of Computer Science (@csmcr), and many other parts of the University: (engineering, natural sciences, social sciences, biology, medicine and health etc) and support staff at the University of Manchester. (@UoMCareers, @alumniUoM, @OfficialUoM)

Thank you Carole Goble for building the community that supported me through postgraduate study. Thanks for creating the environment which this book was written in, especially the e-Science lab, Information Management Group (IMG), Software Sustainability Institute (software.ac.uk) and their spin-offs. Thanks for patiently re-teaching me how to write better by covering early drafts of my Masters thesis in red ink and less patiently (on subsequent revisions) swear words. 🤬

Thank you Steve Furber for playing guitar in our “boy band” Tuning Complete, see chapter 27. All we’ve got is your bass guitar, three chords and the truth. 🎸

Thank you Jim Miles for encouraging me to write a book shortly after you offered me a job. I thought you were joking (about the book) but it actually turned out to be another one of your great ideas. Thanks Jim. 🙏

I’d also like to thank the only three people in the whole world who’ve had the misfortune pleasure of reading all of my PhD thesis cover to cover; Robert Stevens, Anil Wipat and Steve Pettifer. I suspect it was as painful for you to read as it was for me to write it. Thanks Robert for your relentless patience and giving me a well timed, well aimed kick up the (proverbial) arse to write this book in the Midland Hotel, Manchester at the May ball.

So, thank you colleagues for being collegiate. You make the University of Manchester an enjoyable place to work.

#### 0.9.3.1 Thanks to academic staff

Thanks to past and present academic colleagues (see figure 0.15), PhD students and academic staff at the University of Manchester (and elsewhere) who have contributed to this guidebook and the environment it was written in.

• Thanks to David Walker for his book Energy, Plants & Man which inspired the conversations and pictures idea behind this book.

So thanks scientists (and engineers) for being scientific and engineering. 🙏

### 0.9.7 Thank you Bath

Thanks to the University of Bath for your excellent Postgraduate Certificate in Education (PGCE) course. I graduated with a PGCE in Science in 2011 and have been heavily influenced by the fantastic work of the schools in Swindon (section 0.9.9), Shaftesbury (section 0.9.8) and Stockport (section 0.9.10) where I worked. I also learnt heaps from fellow students on the course and its course leaders:

• Steve Cooper, Chemistry
• Malcolm Ingram, Biology

So thanks Bath for the initial teacher training (ITT), TeamBath™, the medicinal Aquae Sulis and the beautiful Cotswolds Area of Outstanding Natural Beauty (AONB). 🙏

### 0.9.8 Thank you Shaftesbury

Thanks to Chris Almond, David Ball, David Booth, Caroline Dallimore, Stuart Ferguson, Caroline Moss, Mr Travers and all the other staff and students at Shaftesbury School who hosted my first PGCE teaching placement, see figure 0.20. Thanks also to my fellow Bath trainees Katharine Platt, Harriet Edwards, Vicky Dury and Joan Shaw for sharing your knowledge through peer learning and peer instruction. Thanks Joan for keeping me awake on the long and winding west country roads to and from deepest darkest Dorset. Thanks for sharing the heavy burden of driving too.

So thanks Shaftesbury for lessons on top of Gold Hill.

### 0.9.9 Thank you Swindon

Thanks to headteacher & physicist Clive Zimmerman, his team of staff, Mr M. Carter, Mr K. Thomas and the students of Greendown Community School (now Lydiard Park Academy) in Swindon, Wiltshire for hosting my second PGCE teaching placement. It was fun teaching you about electromagnetic waves using Alom Shaha’s jelly babies and kebab sticks shown in figure 0.21.

Figure 0.21: Alom Shaha demonstrates his awesome wave machine. Physics and jelly babies, what’s not to like? You can also watch the 4 minute video embedded in this figure at youtu.be/VE520z_ugcU

So thanks Swindon for being great and western and Swindon Town Football Club, the best football team in the whole of the West Country. Proper job. 🙏

### 0.9.10 Thank you Stockport

Thanks to headteacher Joanne Meredith, her team of staff and the students at St. Annes Roman Catholic High School, Stockport for hosting my Newly Qualified Teacher (NQT) year. Thanks to Rebecca Dann, Michael Doody, Keith Doran and other members of the alternative (Elizabethan) staff room for your emotional, moral and practical support throughout a challenging year fuelled by my midlife crisis. According to the Manchester Evening News, St. Anne’s is “the forgotten school” , see figure 0.22, but I’ll never forget you or the lessons you taught me.

So thanks Stockport for being Stopfordian. Thanks for the magnificent Stockport Viaduct and for The Hatters: It’s all that matters, Stockport Hatters. 🙏

### 0.9.11 Thank you schools

Thanks to all the schools who’ve hosted our undergraduate students as part of an ongoing partnership between the University of Manchester and local schools called Coding their Future, see figure 0.23:

Thanks to Mr Shaw for hosting our primary school codeclub.org. Thanks to Mr Ince and Drew Povey for showing me around Harrop Fold School (now The Lowry Academy) in Salford, host of the Educating Greater Manchester television series on Channel 4.

Thanks to all the schools who interviewed me for my Newly Qualified Teacher (NQT) year. Doing interview lessons, meeting your students and your senior leadership teams was a gruelling but fascinating magical mystery tour of the UK education system, both public and private. These interviews were very productive failures:

So thanks schools, for all the excellent work you do educating people, whatever their background. 🙏

### 0.9.12 Thank you Oxford

Thanks to Martin Clutterbuck, Rebecca Clare, Richard O’Beirne, Simon Witter, Will Wilcox, Gavin, Howard, Isobel, Jess, Paddy, Sara, Spiro and everyone else in the journal production team at Blackwell Science Ltd for looking after me in my first job as a freshly minted graduate.

Figure 0.26: I’m with Longfella (aka Tony Walsh) in believing that THIS is the place! You can watch the full 4 minute video embedded in this figure at youtu.be/PszMmYpQjPo 🙏

So thank you for the music, the songs I’m singing. Thanks for all the joy they’re bringing. Thanks Manchester for the best football team in the world and being Mancunian, see figure 0.26. This is the place!

### 0.9.15 Thank you Coventry

Thanks to Phil Harris, Steph Harris, Alan Gear, Jackie Gear, Ally, Neil, Esther, Francis Rayns, Graham Smith, Jeremy Cherfas, Morgen Cheshire, Margi Lennartsson Turner, Lady Godiva (see figure 0.27) and everyone else at the Henry Doubleday Research Association (HDRA) and Coventry University for hosting my industrial experience year during my undergraduate degree.

So thanks Coventry for naked women on horseback, a magnificent cathedral and the industrial experience. Thanks for being the place where I bumped into Bryan Mathers, see section 0.9.23. 🙏

### 0.9.16 Thank you Abisko

Thanks to Malcolm Press, Helena Björn van Praagh, Terry Callaghan, Jackie Potter, John Lee, Mats Sonesson, Nils-Åke Andersson, Rosie, Nick, Dylan, Karin, Kjell, Lennart, Marion, Martin, Ulf and everyone else at Abisko Scientific Research Station / Abisko Naturvetenskapliga Station (ANS, see figure 0.28) for hosting me as a summer research student investigating the effects climate change on subarctic heathlands. 2 Easily the best summer job I’ve ever had! 🇸🇪

So thanks (tack) Abisko for all the saunas, fika, midnight sun and Swedish hospitality. 🙏

### 0.9.17 Thank you America

Thanks to the British Universities North America Club (BUNAC) (see figure 0.29) for sponsoring my Exchange Visitor Student Visa which allowed me spend an awesome summer cooking breakfasts for guests at the Phillips Beach Plaza Hotel in Ocean City, Maryland. If the way to a person’s heart is through their stomach. then I travelled to the heart of America through its big breakfasty stomach. Thanks to Andy B. for flagging it. 🇬🇧🇺🇸

Thanks to Mitch at Green Tortoise Adventure Travel for driving, entertaining and feeding a bus load of us gentle people with flowers in our hair from San Francisco to New York via Chicago and some of America’s finest wildernesses (and cookouts) in Nevada, Utah, Wyoming, South Dakota, the Yellowstone, Grand Teton and Badlands National Parks.

Thanks to Tom and Letty Gochberg for your excellent hospitality in New York City, your transatlantic history lessons and showing me the very best that Manhattan has to offer. You can hear it in my accent when I talk, I’m an Englishman in New York. Thanks Pat, Colin and Rob Willmott for the introduction via the Single-handed Trans-Atlantic Race (STAR) in Plymouth, Devon from where the Mayflower (eventually) set off for the so-called “New World” in 1620, see figure 0.30.

Figure 0.30: Speedwell: No New Worlds was an installation in Plymouth that invited the public to reflect on the legacy of the Mayflower’s journey, colonialism and the ecological state of our planet during the Mayflower 400 commemorations in 2020. The words remind us that while America may have been a “new world” to Europeans it had already been occupied by indigenous people for thousands of years. You can also watch the 4 minute video embedded in this figure at youtu.be/Y2Ya4d1oSQc

Thanks Timo Hannay for letting me gatecrash the best party in Silicon Valley: Science Foo Camp (#scifoo) at the Googleplex in Mountain View, California in 2007 and again in 2009. Thanks to Cat Allman, Sergey Brin, Chris Di Bona, Tim O’Reilly and Larry Page for hosting scifoo.

Thanks Joanne Luciano for showing me the sights of Cambridge, Massachusetts. Thanks to Ewa Deelman, Yolanda Gil and Bertram Ludäscher for hosting transatlantic workflow collaborations at the San Diego Super-duper-computer Center (UCSD) & University of Southern California (USC) with help from Carole Goble and funding from the Engineering and Physical Sciences Research Council (EPSRC).

So thanks America, I love you guys! 🇺🇸 Thanks America for being American. 🙏

### 0.9.18 Thank you Moravians

Thanks to Thsespal Kundan, Principal of the Moravian Institute in Rajpur, Dehradun, Uttar Pradesh, India for hosting me and my friend Doug fresh out of high school on a gap year. We learned loads as visiting supply teachers of English and Mathematics, thanks to an introduction from a mutual contact Angus Barker, see figure 0.31. 🇮🇳

Thanks also to the Moravians in Manchester at Fairfield High School for Girls(see section 0.9.11) for hosting undergraduate Computer Science students as part of coding their future.

So thanks Moravians (and Angus) for life changing and formative experiences. 🙏

### 0.9.19 Thank you influencers

Some of the most important influences on this guidebook are people I’ve only met very briefly, virtually or not at all (yet).

• Thanks to Gayle Laakman McDowell (@gayle), for your cracking series of books which have been very useful resources both for students I’ve worked with and me personally
• Thanks to Yihui Xie (@yihui) and contributors to bookdown.org, the software used to produce this book alongwith the comprehensive and well-written documentation on using it.
• Thanks to Bronnie Ware for your book The Top Five Regrets of the Dying which helped me to re-align my values and priorities when they were all out of kilter
• Thanks to Jo Hobbs at Lancaster University for advice on placements and employability in undergraduate teaching

So, thanks influencers for being influential. 🙏

### 0.9.20 Thank you interwebs

Thanks to the artists, blaggers, bloggers, cartoonists, columnists, doodlers, diarists, essayists, film-makers, journalists, photographers, podcasters and writers whose words and pictures I’ve enjoyed reading, watching and listening to via the magic of the interwebs, see figure 0.32.

So here are some people whose stuff I read, watch, listen to or use, maybe you’ll enjoy their words, pictures and software too:

Figure 0.33: Artist Steven Appleby explains some simple techniques for drawing. Useful techniques that can also be applied to writing anything, playing music, living life etc. The 6 minute video embedded in this figure can also be viewed at youtu.be/G_Vz7gTh1VE

So, thanks writers for writing. Thanks for penning, drawing and recording stuff that has provoked, informed, entertained, influenced and inspired me. 🙏

### 0.9.21 Thank you githubbers

Thanks to everyone who has contributed via github, listed below in order of github usernames. I will credit any github contributors here, small or large. Even the typos, it all counts. I don’t care what operating system you are using either, see figure 0.34. You can easily add yourself to this roll call (see section 0.8) by correcting my delibreate mitsakes. 😉

Aman (@amanrana1), Keith Mitchell (@apiadventures), Zee Somji (@ezeethg), iliketohelp (@iliketohelp), Jan Machacek (@janm399), teobalmos (@teobalmos), Tsvetankov (@Tsvetankov), Richard Gourley (@richardgourley), Tristan Maat (@TLATER), Safder Iqbal (@safderiqbal), Merve Turan (@mervturan), Mehuli Basu (@mehuli12), Rui Xu (@Ray7788)

So, thanks Wikipedians for being Wikipedia. 🙏

### 0.9.23 Thank you Bryan

Many of the illustrations for this book have been drawn by the very talented Bryan Mathers @BryanMMathers shown in figure 0.36.

Bryan is an artist, visual thinker, entrepreneur and listener who turns stories into pictures. He also happens to have a Bachelors degree in Computer Science from the University of Glasgow. As a renaissance man, his combined skills in art, science and engineering made him the perfect fit for illustrating this guidebook. You can find out more about Bryan at bryanmathers.com and visualthinkery.com. I’m very glad we randomly bumped into each other at the #wikiedu20 conference: wikiedusummit.coventry.domains.

Figure 0.36: People tell stories and stories paint pictures. Bryan Mathers, who has illustrated much of this guidebook, telling stories at TEDxGalway in 2021. You can watch the full 15 minute video embedded in this figure at youtu.be/IapGM5ZYBEw

So, thanks Bryan for your witty illustrations, this book wouldn’t be the same without your visual thinkery. 🙏

### 0.9.24 Thank you St Laurence

Thanks to St Laurence comprehensive school (st-laurence.com), a community I am proud, lucky, privileged and grateful to have grown up in and still be part of decades later: Adam, Alan, Andrea, Andrew, Anna, Bouncing Barney, Charlotte, Catherine, Clare, Dan, Doug, Debbie, James, Jenny, Jim, Jo, John, Jon, Lou, Marcus, Marjorie, Matthew, Philip, Portia, Richard, Sasha, Scott, Simon, Sophie, Sophia, Stephen, Steve & Wilf. I’m especially grateful for the friendship of former St Laurence school students I’ve enjoyed music, cycling, football, walking, travelling, holidaying, drinking and camaraderie with, see figure 0.37. So:

I’m looking forward to the next revolution of our ongoing adventures.

Special thanks to former St Laurence school student and current sixth form head Aidan Blowers for showing me around The Clarendon School in Trowbridge, Wiltshire and leading by example. Aidan’s performance as Lord of the Dance (wearing a white shirt in figure 0.38), inspired the ongoing musical experiment that is Tuning Complete.

Thanks to all my teachers at St Laurence school, some of whom can be seen in figure 0.39.

Thanks to the rest of my St Laurence school teachers not pictured in figure 0.39. In alphabetical order: Phil Arthur, Sally Arthur, Maggie Bignell, Jackie Bolton, Tony Brooks, Dave Brush, Mrs. Buthlay, Andrew Butterworth, Cathy Cooper, Ed Corrin, Mrs Davies, Brian Ellis, Myra Ettridge, Sue Glanville, Ms. Gledhill, Roger Greenwood, Barry Hales, Amanda Hodges, Steven Hollas, Maddy James, Mr Jones, Madame Lindsay, Karen Long, Sheila Macdonald, Simon Mitchell, Lee Musselwhite, Tim Noble, Roger Norgrove, Dave Pegg, Angela Pendennis, Sally Rose, Brian Reynolds, Steve Stretch, Mr Sadler, Mike Sullivan, Phil Smith, Rob Townhill, Beryl Tucker, Chris Watters, James Wetz and Bill Wheeler.3

Thanks to all of the school governors for holding the leaders of St. Laurence to account. I’m a #StateSchoolProud member of the 93percent.club. 💪

So, thank you to the community that is St. Laurence School, for enabling my GCSE’s followed by A-levels in Physics, Chemistry, Biology and General Studies. Thanks for educating me (and many others) the West Country way. Proper job! 🙏

### 0.9.25 Thank you Fitzmaurice

Thanks to my Fitzmaurice Primary School school teachers: Mrs Cripps, Miss Clarry, Morris Clay, Neil Fleming, Mr Jackson, Betty Knowles, Mr. Lucas, Valerie Payne, Miss Sheldon, Hugh Solomon, Miss Uncles and Mrs White. I used to foolishly think it was secondary schools that did all the serious teaching, but they’d be nowhere without the crucial foundations laid in primary school. It takes a whole community (a village) to raise a child and a lot of that starts in primary school, see figure 0.41.

So thanks Fitzmaurice Primary School and Edmond Fitzmaurice for laying solid foundations. 🙏

### 0.9.26 Thank you Branwen

Thanks Branwen Munn, pictured on the far left in figure 0.42, for introducing me to writing loops on the BBC Micro at Fitzmaurice Primary School with help from Mr. Jackson’s code club, see section 27.13. We were lucky to also have access to your very own Commodore 64. Like Emma Mulqueeny I think year 8 is too late. It is unlikely I would have ended up where I am if it hadn’t been for early exposure to computing in primary school.

So thanks Branwen, for all the breakdancing, birdwatching, music and computing.

### 0.9.27 Thank you NHS

Thank you NHS for all the healthcare you’ve provided for me and my family from our cradles to our graves, see figure 0.43. I had taken your services for granted until I thought I was on my deathbed, see section 2.2.7. Thankfully, I was granted some extra “Fergie time” from the Grim Reaper. ☠️

So, thanks NHS ❤️ for all the publicly funded healthcare. 🙏

### 0.9.28 Thank you family

To my family: wife, son, mum, dad, brother, sister, μαμά, μπαμπά and extended family: I’m lucky to have been taught by you and that you’ve always been there when I needed you. 🇬🇷🇪🇺🇬🇧

So, thanks to all my family scattered around the world for your unconditional love.

Για πάντα σ’αγαπώ. 🙏

Hello, my name is Duncan Hull and I’m currently writing this guidebook for undergraduate and postgraduate students as part of my day job at the University of Manchester where I’m a Senior Lecturer (≈ Associate Professor) in the Department of Computer Science.4

So what’s my story? I’ve been gainfully employed as a paperboy, supermarket cashier, shelf stacker, sausage packer, computer hacker, pork pie filler, plongeur, chef, dogsbody, field assistant, database administrator, deli counter server, consultant, matchday steward, envelope stuffer, high school teacher, postdoc, research scientist, chairperson, software engineer, lecturer, external examiner, tutor and scholar. Like many people, my path has been a bit of an Odyssey or what Helen Tupper and Sarah Ellis call a “squiggly career”. It’s highly likely that your career will not follow a neat linear trajectory either, also known as a portfolio career.

Beyond the paid stuff, I’ve done a range of voluntary work too, serving as a competition judge, fundraiser, code club & coderdojo leader, rabble rouser, digital council member, school governor, curator, librarian, beer drinker, wikipedia trainer, journal clubber and editor. But as Ronnie Lane and Ronnie Wood (figure 0.45) once said, I wish that I knew what I know now, when I was younger.

This guidebook documents some of what I know now, that I wish I’d known, when I was younger. If you’re starting your career, I hope you find these insights and exercises useful. I’ve sat on both sides of many interview tables, as interviewer and interviewee. I have had some spectacular failures, alongside some modest successes, and have included personal stories where they are relevant.

Most of what I have learned about employment comes from listening to, watching and helping students as they interact with employers on the first tentative moves in their careers, particularly through our industrial experience program, see figure 0.46.

I’ve documented some of what our students have taught me, so reading this book may help you learn from some of their successes and failures.
