Last week I dropped in to the London studio of Fun Kids to be interviewed for the Science Weekly podcast. Host Dan asked me about computer code, where it comes from, and how computer languages work. It was a lot of fun taking part in the interview, and I would like to thank host Dan and producer Imogen for having me along. As always with these things, I thought of better answers to some of the questions on the tube home!
The interview was recorded to coincide with the publication of Coder Academy, which is out now and provides an introduction to Scratch programming and simple web design. The book is aimed at children aged 7-10 years old, and includes lots of interactive activities on the page. You can take Scratch further with Scratch Programming in Easy Steps and Cool Scratch Projects in Easy Steps. Follow those links to get free chapters and bonus content.

As you might have seen, my new book Coder Academy is out now. The book is mostly based on Scratch, the free coding language popular in schools. There's also a chapter about coding a web page.
Aimed at children aged 7-10 years old, the book uses a mixture of on-the-page and on-the-screen activities. For example, there's a section where you use the stickers in the back of the book to design a sprite, and see how to make it in Scratch. There's also a pattern to complete in the book that you turn into a tune in Scratch.
In the back of the book is a poster, a coding pairs card game, press-out paper robots to assemble, and stickers for designing sprites and marking your progress through the book.
I'm delighted with how the book has been received. How It Works magazine gave it a five-star review and said: "The need for youngsters to become coder-savvy is as important as ever. For those seeking to inspire the next generation to go down this important path, Coder Academy would make a most welcome addition to the bookshelf. Coder Academy... transforms a typically dry subject into something much more palatable through informative and enjoyable activities."
The Week Junior made it book of the week and said: "If you're looking to code for the first time, then this book is the perfect way to get started."
LoveReading4Kids made it non-fiction book of the month and said: "This well-designed, interactive workbook provides a really good introduction to coding for children. It breaks it down into fun, step by step exercises and each bright, visually attractive page sets children tasks to do, with sticker rewards when they get the answers right... As the author himself has said, coding is highly creative, and even without the press out robots on the end pages, this is a fun, appealing and stimulating approach to one of the key skills of the 21st century."
TechAgeKids wrote: "Coder Academy is a fantastic activity book for tech-loving kids and would appeal to children from age 6 and up... We love the combination of coding, craft and design. Coder Academy would appeal to children with a wide range of interests and who are new to coding."
Parents in Touch wrote: "With extras at the back of the book including a game, a pull-out poster, stickers, and even a robot model to press out and make, this is the must-have book for any future junior coders. It's straightforward and does not require any previous knowledge. Ideal for coding clubs in school as well as for home use."
Thank you to all those publications and everyone else who has written a review or is otherwise helping to spread the word. Visit my Coder Academy mini-site for a free sample chapter, a Scratch sprite pack, desktop wallpaper, bonus content and more. You can find links to order the book here.

Want to make a case for the Raspberry Pi that's environmentally friendly, cheap and requires no special equipment? Paper or card is the perfect material! To celebrate the publication of the fully updated third edition of Raspberry Pi For Dummies, we have created two new case templates you can use to house a Raspberry Pi 3, Raspberry Pi 2 or Raspberry Pi Model B+.
The first design features the new For Dummies brand, showing the Dummies Man with a slick new haircut and glasses. Download the PDF template for the branded case here. It's not just the Dummies Man who's changed: the design of the book interiors has been completely updated too. Check out my PDF sampler of Raspberry Pi For Dummies to see what it looks like now.
There's also a design with minimal branding that you can use for decorating your own case. In the photo, the case on the left was printed on coloured paper that had been painted by my son. I did also look to see whether there were any cool magazine adverts I could make a case out of, but it seems like music mags have far fewer full page ads than they used to. Tweet me your box art. I'll be curious to see your designs! Download the lightly branded case here.
If you have an older Raspberry Pi, you can still download the original case we made when the first edition of the book came out. It features the old For Dummies branding, but will keep your Model B nice and snug in the cold winter months. Download the original Raspberry Pi case template here. (The new edition of the book still includes advice on setting up the original Raspberry Pi models, by the way - there are lots of them out there, and it would be good to think they can be put into service somewhere).
The original paper case, called The Punnet, was designed by Ian McPhee, who kindly allowed us to create the branded version. Find out more about the new edition of Raspberry Pi For Dummies here.

It's publication day for the third edition of Raspberry Pi For Dummies!
Since the second edition was published in 2014, there have been quite a few changes in the Raspberry Pi world. Most obviously, there has been the launch of the Raspberry Pi 3 and the Pi Zero, but there have also been quite a few changes in the software. There's a new desktop, a new Python editor (Thonny), the release of Pygame Zero and Scratch 2, and the latest version of Sonic Pi. For this new edition, we've updated the book to reflect all these changes, and have updated the code throughout for Python 3. There's a new chapter on using Pygame Zero, and my co-author Mike Cook has completely rewritten the electronics section, including an introduction to GPIO Zero and Scratch so you can get your first circuit up and running faster. The Sonic Pi chapter has been updated for a greater focus on live coding and experimentation.
We have tried to be as inclusive as possible, so the book aims to cater for the Model B+ and later, and provides pointers for earlier machines where possible. The set-up instructions include guidance for the original Model B and Model A, providing a comprehensive reference for setting up the Pi. The Scratch chapter introduces Scratch 2, but the main project uses the original Scratch which performs faster and is available on older Pi models too.
The book still includes coverage of setting up your Pi, using the Linux desktop and shell environment, LibreOffice, GIMP for photo editing, Kodi media player software, Python, Scratch, programming Minecraft, Sonic Pi, and building electronics projects. It also includes ten inspiring projects and ten software packages to try.
Since we published the previous editions, the For Dummies series has been rebranded with a redesign inside and out. The new design looks much cleaner and more modern to me, so I think you'll like it. If you'd like to take a look, I've updated the free PDF sampler of Raspberry Pi For Dummies here. That includes two chapters, and the table of contents in full to give you an overview of the book.
As always, thank you to everyone who has supported the previous editions of the book by buying it, reviewing it, and telling others about it. There wouldn't be a third edition without you, and it's been wonderful to create a book that has been so well received. Thanks also to Mike for bringing his electronics expertise, and the team at Wiley for all their work behind the scenes on editing, proofreading, project management and marketing.
The book is available now to buy or order in real bookshops and online. You can find some links to shops stocking Raspberry Pi For Dummies here. There's lots more information about the book here.

The May issue of the MagPi, the official Raspberry Pi magazine, included the Google AIY kit, which enables you to add artificial intelligence to your Raspberry Pi. Specifically, it provides a voice recognition system, based on Google Home and similar to Amazon Echo. You press the button, ask a question out loud, and the box uses the cloud to analyse your question and find an answer for you. The answer is spoken in a friendly female voice.
It's been a busy few months, but I have now, finally, got around to assembling it. There were a few areas where the instructions were a bit confusing, probably because Google has redesigned its cloud API website since the instructions were written. At first it wouldn't work because it said I had to change some basic settings. It turned out that you have to enable all the activity controls, including ticking the box for using your browser and app history. I can see how using your personal data can make the service better, but the service is stopped from working without it. That sounds to me like Google is using services like this as leverage to get personal data.
So now, I have my assistant, sat on my desk. the button is usually on the top, but I've turned the box on its side and put a friendly face on it using stickers. Here's a video:
The voice recognition is pretty good, although the service is quite US focused, at least initially. When I was asking about places in my area, it was mishearing them as places in the US at first. When I asked about the weather in a local town, I was given the weather in another local town. Often the answer includes complete information so you can tell what the device heard, but sometimes it doesn't. I was hoping to be able to use it as a voice activated calculator, and so far in my tests it's performed perfectly. But it doesn't repeat the question, so there's a risk the question hasn't been correctly heard and I can't validate that. (You can fit a screen and then see what it understood, but that defeats the object).
It performs well for general knowledge questions, the time and weather forecasts. It knows a few funny jokes (it hasn't repeated yet, but I don't want to use it all up so I'm not asking it to tell me a joke too often). You can't set a reminder, get it to tell you the latest news, or shut it down using a voice control yet. Although the great thing is that it's hackable, so you could add all kinds of features or use the API for controlling different devices.
I am probably the last person in the country to assemble one of the original AIY kits (like I said, it's been a busy few months), but the Raspberry Pi Foundation advises anyone still interested in getting hold of one to subscribe to the MagPi newsletter. It says: "We can’t say for sure that the AIY Projects Voice Kit will be available for purchase, but we are pretty confident that a longer term solution can be found."
It would be great to see this become a commercial product, so that more people can enjoy building it, hacking it, and chatting to it.

This year is the 20th anniversary of www.sean.co.uk, making it older than Facebook, Twitter, Wikipedia and even Google. Thank you to everyone who's visited over the last two decades!
To celebrate, here are another 10 pieces of my favourite content across the site. See the first 10 (and a screenshot of my first website design) here.
To keep up to date with significant new content, subscribe to my newsletter.
- Under Pressure - An article about hostile environments training for journalists. One thing I learned is that I'm not really cut out for it.
- Interview with Jakob Nielsen about accessibility - Accessibility is all about making websites usable by people who have vision, mobility or other impairments. I wrote one of the first articles in a mainstream magazine on this topic, and I've tried to make sure my site is as accessible as possible over the years.
- Make an awesome 3D anaglyph website using CSS text-shadow - This article explains how you can use a CSS stylesheet to create 3D text that pops out of the page when viewed with red/cyan glasses. I haven't seen anyone else doing this. At one stage my site had a style sheet switch you could use to make the whole site go 3D. My later book Cool Scratch Projects in Easy Steps shows how to use 3D glasses in Scratch games.
- Black (Colin Vearncombe) interview - This interview from 1993 with Colin Vearncombe, of Wonderful Life fame, remains a favourite of mine. I greatly enjoyed meeting Colin, and we kept in touch over the years. I saw him for many memorable concerts and built his first website. Colin sadly passed away in 2016, leaving us way too soon, but with a wonderful legacy of recordings.
- Among those dark satanic mills - My account of being a volunteer performer in the opening ceremony of the London 2012 Olympics. It feels a long time ago now, but this article brings back many happy memories of the summer that London welcomed the world, and I got to play a small part in the spectacular surprises.
- How to write a novel - My key lessons from the lengthy creative writing process for my music business novel Earworm, originally published as University of Death. I greatly enjoyed the writing process and hope to write another novel one day. Earworm is out now on Kindle and in print, and makes for a great holiday read! :-)
- Proofreading test - For this test, I added errors into one of my own articles and published it online so that visitors could try correcting it. It's been a popular feature of the site over the years.
- My Travel Photos Gallery - I have been extremely fortunate to travel to places such as China, Singapore, Australia, Japan, New York, San Francisco and South Africa. A couple of years ago I undertook a large project to put hundreds of travel photos online, including a gallery dedicated to my home city of London. Each photo has its own sliding puzzle game. You can also still see my Rock and Pop gallery, with photos of Radiohead, Pixie Lott and Slash, among others.
- How to sell your music on iTunes and Amazon MP3 - I used to write a monthly column about the internet for musicians. This is an article I wrote a few years ago about how to get your music into the major stores. It's been popular with musicians, together with my list of places you can sell your music online.
