Linux Voice Interview with Raspberry Pi Education Team

Back in February at the Raspberry Jamboree, my colleagues Carrie AnneClive and I were interviewed by the Linux Voice team about Raspberry Pi‘s views on computing education.

Linux Voice is a fantastic new free software magazine which was funded by a crowdfunding campaign on Indiegogo at the end of last year. I backed it as soon as I heard about it, and I eagerly anticipated the arrival of its first issue. We’re now five issues in and I’ve loved every one – the guys are doing a great job. I highly recommend a subscription!

From the beginning they committed to making all their articles available for free after up to nine months from publishing, released with a Creative Commons licence. Some material has been published early, such as the brilliant piece on Grace Hopper from Issue 3. Luckily for us, the interview they conducted with us, which featured in Issue 2, was released in full earlier this month, so I’m pleased to be able to share it now!

2013 in Review

This year I’ve learned lots, run events, helped mentor young people, contributed to open source, engaged in much community activity, made and developed some strong friendships and built myself a new career.

OH Digital

I began this year working as a web developer at OH Digital, having started there just two months before the previous Christmas. OH Digital are primarily a WordPress development agency; initially I was sceptical of the use of WordPress as a full CMS, but grew to realise its potential the more I used it in a range of commercial websites. We specialised in delivering a full build to a client, from specification, through design and development iterations to the launch, and also hosting, administration, third-party integration and maintenance. Our design work always was done externally, as we had no in-house designers, but had connections with quality local design companies. It meant we got to concentrate on development according to the specification (which we’d created ourselves by working directly with clients) and outsource the visuals and interfaces to professionals who could meet our clients’ needs and provide us with excellent designs to work from.

Working on all levels – specification, user experience, front-end markup and styles, back-end programming and Linux systems administration – gave me excellent experience in working professionally, being involved in the whole build, and meant I got to see a project through from concept to launch and see it in action once live. And being lucky enough to work alongside very talented designers meant I was always very proud of the piece of work we’d produce after each project – not only because of the delivery of the technical solutions involved but because the websites we made looked brilliant. I would be proud to say I worked on a site and would often show people the finished product. Here is a selection of the projects I worked on at OH Digital:

Manchester Raspberry Jam

Throughout the year I continued to run the Manchester Raspberry Jam. This started in July 2012 and I ran one every month since then, skipping just two (March, for the Jamboree, and September when I was in Berlin) which we usually had around 30 – 60 people attending. The Manchester Jam was the first in the UK and they soon spread all over the country and the rest of the world. The events I ran were very practical focused, and we regularly had a range of people attending – including young people and families, and everyone was encouraged to collaborate on projects and learning. At the event in November – Manchester Raspberry Jam XVI – we had 80 people signed up and a further 20 on the wait list. This event was attended by several members of the Raspberry Pi Foundation and we ran a full track of talks upstairs as well as the usual hacking downstairs. The talks were all video recorded by a volunteer AV Team (thanks Les, Dan, Olly & Tony).

A particular success of the Raspberry Jam has been one of the young people I have mentored for the last couple of years – 14 year old Amy Mather (known as Mini Girl Geek). Amy is a really keen and very bright young coder and maker. At last December’s Jam, we started a small coding exercise – a test-driven implementation of Conway’s Game of Life in Python, for her to learn coding techniques and the language of Python. She came back to the next Jam in January with a fork of the original code, ported to work with PyGame, a gaming library for Python, rather than just drawing ASCII characters in the terminal. She improved upon the PyGame version some more at that Jam, adding features and learning more about Python, and then came back the next month with a version of the code powering a small LED matrix from a Raspberry Pi and an Arduino. She was then asked to present this at the Raspberry Jamboree in March (just 13 years old at the time). The video of her presentation was a big hit online (currently over 50,000 views) and was praised by many people including Kent Beck and Jimmy Wales. The video was also featured on the Raspberry Pi blog.

Amy went on to speak at bigger events such as CampusPartyEU at the O2 in London (on stage with George Osborne and Jimmy Wales), Wired Next Generation, Wuthering Bytes, and won the European Digital Girl of the Year Award presented in Lithuania. I’m very proud of everything she’s achieved and I’m pleased to have been lucky enough to be one of the many people who helped her along the way – and given her the chance to shine.


I also attended an event at Manchester University for STEM Ambassadors to be introduced to the Raspberry Pi. After meeting the coordinators of STEMNET, we discussed the idea of running a Raspberry Jam for schools – and so over several emails and phone calls, we put an event together, invited schools to attend and ran the first STEM Raspberry Jam. This kickstarted Raspberry Pi activity in the STEM network of the North West and there have since been a number of Raspberry Pi sessions run by the STEM team with a team of trained Ambassadors – in schools and colleges around the North West, introducing young people to programming and making projects with the Raspberry Pi.

Pi Weekly

About six months ago I had an idea to set up a weekly Raspberry Pi email newsletter featuring news and projects from the community – and invited Ryan Walmsley to join me in running it. We called it Pi Weekly. We grew steadily and a few weeks after launch it was featured on the Raspberry Pi blog – which sent out subscriber count through the roof. We then sought sponsorship to continue running at the new capacity, and developed new features as time passed. I worked on the website, the newsletter and the generator over time, and wrote up a full account of its evolution on my blog. At the end of 2013, we’d sent out 28 issues and had over 5,600 subscribers. This week, Pi Weekly was translated in to French by a Pi enthusiast with a Raspberry Pi news website.

Manchester CoderDojo

Another project I’ve been involved with in the last year has been the Manchester CoderDojo. This is a youth club for kids learning to code and make things. This was started in December 2012 by Steven Flower, and we started out at Madlab but after a few months outgrew the space and moved to a new venue at the Sharp Project. I volunteered as a mentor and coach at each of the events in 2013 up to November, where I ran sessions in Python, HTML/CSS, WordPress and using the Raspberry Pi. I recently revamped the website and set up a Pi Weekly style newsletter we now send out to parents and supporters.

User groups and Conferences

I have been attending user groups in Sheffield and Manchester since late 2009 / early 2010, and this year has been my peak in attendance. This year I’ve been regularly attending Python North West, PHPNW, XP Manchester, manc.js, Manchester Maths Jam, IMA North West TalksManchester Werewolf and Preston GeekUp, as well as helping out with Manchester Girl Geeks, volunteering for Manchester CoderDojo and running Manchester Raspberry Jam. I visited a few events further from home, as one-offs, such as the York Raspberry Jam and Blackpool GeekUp I gave many talks at these user groups throughout the year, the majority related to Raspberry Pi. I gave a total of 32 talks in 2013, including a discussion panel at the Raspberry Jamboree and a couple of talks at user groups in Berlin.

I also attended the first Raspberry Jamboree (Manchester), my first MozFest (London), my second Oggcamp (Liverpool), my third Barcamp Blackpool, my third Code Retreat, my third U3, my third Maths Jam Conference (Stone) and my fifth PHP North West conference (Manchester).

Open Source

This year I submitted my first patch to Ubuntu – a fix for the Guake package (Quake-style dropdown terminal) which was merged in to Ubuntu 13.10 (Raring Ringtail) and then-upcoming 13.10 (Saucy Salamander). See the changelog on launchpad.


I also fixed minor bugs in a number of smaller projects such as the Python Koans, as well as working on a number of small personal and community projects which are open source, such as Python Intro, Acacia Acuminata, Acacia Vanilla and Pi Weekly.

My (public) GitHub contributions of 2013:


from on 4th January 2014.

Bravery Award

I was also presented with an award for the river rescue I conducted the previous September with friends from the canoe club. We each received the Chief Fire Officer’s Commendation for bravery at a presentation in the Ramsbottom Fire Station. See the articles from the Manchester Evening News: Award for Brave Kayakers who Saved Man’s Life and the Greater Manchester Fire & Rescue Service: River Rescuers Presented with Bravery Award

Raspberry Pi Foundation & 2014

In mid-October, around the time I celebrated 1 year at OH Digital, I was invited to visit the Raspberry Pi Foundation and was offered a job there. Obviously I accepted, and made plans to move to Cambridge. Prior to this opportunity I had no intention to leave Manchester, and certainly wasn’t looking for a reason to move on from my job or from the city – but the chance to work full time promoting the thing I have dedicated much of my time and effort to advocate purely because I believed in it and the Foundation’s mission – meant that there was no hesitation in taking the opportunity to move. I moved at the end of November, two weeks after my final Jam – which was a huge success, and a great chance for me to show the Foundation what I’ve been building up over the last 18 months.

Around the time this happened I had just started taking driving lessons again, and I managed to pass my test a week before I moved to Cambridge – although I didn’t get a car until around Christmas. Finally at the age of 25 I am no longer a pedestrian!


My role at the Foundation will be in development and outreach. Initially I’ll be working on a revamp for the website, which will be launching early 2014, diversifying the content to include educational resources, projects and such in a way that helps young people learn and aids teachers delivering material, so as to progress with the Foundation’s educational objectives. Also I will be working with young people, speaking about Raspberry Pi at events, helping to make the learning experience with Raspberry Pi more engaging, doing general outreach and fulfilling the Foundation’s mission as well as writing educational material, building tools, working on Pi projects and doing further development and maintenance on the website. I was there for three weeks before heading back to Sheffield for Christmas, and loved it so far. I’m getting on really well with the team, and getting the chance to see the amazing things we have in development. Big things coming in 2014! We hit the 2.3 million sales mark at the end of 2013, which is incredible. We also have the wonderful award winning teacher and new author Carrie Anne Philbin joining the team (starting tomorrow!) which I’m particularly excited about, and very pleased for her to (like me) be getting the chance to work on what she loves. See my introduction: Welcome Ben! and my first contribution to the Raspberry Pi blog: Pi Powered Ping Pong Pursuit.

I plan to start a CodeClub in Cambridge in 2014. It’s something I’ve wanted to do for a while, but never had the chance. Now I’m working for the Foundation it’s important for me to get involved in this and see how young people learn, how they interact with technology and other people, and what they find interesting and engaging. As well as providing the means for a group of young people to learn to code and build things, I will be learning lots about the process for myself. Starting a CodeClub is something of a resolution of mine for the new year – and I’ll also try to personally do more hands-on projects, particularly with the Pi. I’ll also aim to make my way through some books I’ve had but not worked through yet – particularly Seven Languages In Seven Weeks. It’s about time.

Thanks to all the friends I made in Manchester – particularly those involved in the machinery of the tech community, who really do make things happen for people, and often (without realising it) get the ball rolling for many people’s personal and professional lives, and put them on a path to where they ought to be. Special thanks to Madlab founders Dave Mee & Hwa Young, who gave me the chance to learn, and then the chance to shine; to Andrew Disley, who ran Manchester GeekUp – which was my gateway to all of this; to Jag & Hannah Goraya who ran the Sheffield tech scene (Jag hosted my first ever tech event); to Steven Flower for doing what he does so well, and bringing out the best in people; to Sam Tuke who helps me understand and appreciate freedom; to Jeremy Coates for always keeping an eye on me; to Jon Spriggs for helping me and others do anything we want to do, and for sharing all he has with the world (with such passion); to Robie Basak and Sam Headleand for being alongside me all this year; to Lisa Mather for being like a second Mum; to Les Pounder for making great things happen and living the dream; and to all the geeks of the North West scene who’ve been like a family to me the last few years.

Berlin 2013

I’ve heard lots lately about how cool Berlin is — my friend Martin goes there regularly and hangs out in coffee shops working on projects, and he really enjoys the atmosphere and culture around the city. Another friend Sam recently moved here, and he loves it too. There seemed to be a thriving tech scene, and there’s plenty of interesting things to see — so I thought I’d take my summer holiday there this year. I wanted to go alone too — just for the adventure of getting about and discovering interesting things by myself. I remembered my trip to the Spanish Pyrenees back in 2008 and how I had to make it across the breadth of Spain by public transport on my own, with no real plan, in order to make it back for my flight, and how I met a bunch of cool people along the way. I was really seeking some adventure like this. And I’ll be writing the post as I go along, as reading back over the posts from my past trips reminds me of the detail of the anecdotes and the emotion I went through at the time — things which are easily lost to time if not recorded.

I set off from Manchester in what I considered plenty of time. Arriving at the station to find the train I’d planned on getting was delayed, I waited, and eventually made my way to the airport. the delay had set me back quite a bit so I arrived with less time than I intended to make my way through check-in (which was much less than the recommended time anyway). I had about 20 minutes till the gate closed, so I rushed to the check-in desk and saw a huge queue — then realised that the luggage check-in desk closed 10 minutes before the main check-in — giving me less than ten minutes to get through the queue. Panicking, I realised I had no choice but to make my way to the front of the queue, or probably miss the flight. I plucked up the courage to tap somebody on the shoulder and beg that he let me in front of him — fortunately he was very understanding and let me in, and suggested I move forward to the front — the few people ahead didn’t mind either, and so I got to the desk a few minutes before it was due to close. Then I made my way to the security scanners to find another massive queue. Slightly worried the gate close time was getting close, I waited — and a member of airport staff asked the crowd if there was anyone due to depart before 7am, as they could bypass the queue to make it through in time — mine was 7.15 departure — and it was 6.45 at the time — so I figured it wouldn’t be a problem. I got through and made my way to the gate as they were calling for any remaining passengers to board, so it was fine. Feeling relieved, I took my seat. Note to self: don’t push your luck.

I arrived at Schönefeld airport, retrieved my bag from the baggage carousel and made my way out. I found a ticket machine for the train, and spent a few minutes pressing around to find the correct ticket — meanwhile a queue was forming behind me. I eventually found the ticket I wanted — an ABC Zone day ticket (the airport is in zone C, but an AB Zone ticket will do for the rest of the trip) — and proceeded to attempt to pay for it — but the machine would not take my money (notes). I tried all the different ways I could think of, but not wanting to hold the queue up I left and tried to see if I could get some change. I found a change machine and got a bunch of Euro coins out. I returned to the machine, and watched somebody use the machine perfectly — a green light came on and they inserted a note. The green light never came on for me. the two people in from of me got to the machine and the green light didn’t come on either, so I pointed this out to them (as I heard them speaking English). They tried a card and coins but no luck. I tried after them, and the coin slot didn’t open, the green light for the notes didn’t come on and it wouldn’t take my card. I left and headed for the station to see if I could find another machine. I joined a queue at a machine in the station, behind the people I’d been with at the previous machine, and chatted to them while we waited. Turns out the guy was Irish, from Dublin, and had just moved to Berlin for a year to study Economics, and the girl he was with was local and had arranged to meet him at the airport. Had a great chat with them, and when the machine still wouldn’t take my money, the guy put all three of our tickets on his card and I gave him the cash. Phew! But where to? I didn’t have any plans for the day other than to got to c-base that evening — and probably meet up with Sam, who I was staying with to begin. I thought I’d be happy to head to a random cool part of town and hang out until Sam was available — but really didn’t know where to go. I didn’t have data on my phone and just had a map of the subway system. I called Sam for a suggestion and he said he was available so he’d come and meet me. He called me and directed me to his nearest stop. There are four types of public transport on the Berlin network — the U-bahn (mostly underground), the S-bahn (mostly overground), the metro (trams) and the bus. A zone ticket permits travel on all of these. Many stations have both U-bahn and S-bahn which makes for easy connections, and a few of the main stations are railway stations too — for connections to other cities and further afield by train.

We walked to his apartment and had a bite to eat — we chatted for a while about the developments in the tech scene in Manchester, and he told me about what’s going on in Berlin. After a while I let him get back to work and went for a walk. Sam lives near the former Tempelhof Airport, so I took the chance to walk through it. The airport was built in the 1920s and reconstructed by the Nazis in the 1930s, and has only been defunct since 2008. The airport building still stands, and the runways are still in tact but the fields surrounding it are now used for sports, grills, art exhibitions and such. I took a walk down the runway and then made my way towards Gneisenaustraße where I saw some interesting graffiti — some of it made me chuckle and reminded me that’s part of why I wanted to come here — the attitude and expression of the residents of Berlin is fascinating. Then I spotted some brilliant Berlin postcards in a little art shop and I wandered further and discovered Werderscher Kirchhof – a huge and beautifully green cemetery with incredible architecture seen in massive family monuments. It proceeded to rain heavily so I retreated to the nearest U-bahn station and headed over to Jannowitzbrücke and while waiting to meet Sam for dinner, I was lucky enough to witness a wonderful rainbow over the river — and it was visible as a full semi-circle — which I don’t think I’ve ever seen before!

Sam arrived and we ate at the Ming Dynasty before entering c-base. This night was the meeting of the Ubuntu User Group – which I was looking forward to. My experience at c-base was unexpectedly odd — no-one greeted or really acknowledged us until we entered the members’ area — to ask if we were members. Sam joined recently so he pointed this out and introduced me, then after spotting my Raspberry Pi t-shirt, the guy started telling us about how much better he thought the BeagleBone was. We had a look around and headed back to the bar and got some drinks. Sam went to speak to someone about his membership and so I looked around for someone to talk to — I joined a group at the bar, said hello and said I was visiting from the UK. They basically ignored me, I asked if they were members and they said some of them were, then just carried on talking amongst themselves. I gathered most people there were just hanging out, and saw a small group with laptops running Ubuntu, I assumed they were the ones there for the Ubuntu meeting. I approached the table, said hello and introduced myself to each of the pairs of people in turn, they said hello but barely looked up from their laptops. When I couldn’t seem to engage them at all, and looked around to see everyone else was in closed groups chatting, I just sat and waited for Sam. When he returned, I explained how people had been generally unwelcoming and asked if he knew anyone we could hang out with. Being new to c-base, he didn’t know many people there yet, and couldn’t see anyone he recognised. He asked one of the bar staff about the Ubuntu group and he pointed at the group of people with laptops, and pointed out an older man aside form them who he said was the group organiser. We approached him and ended up sitting with him for an hour or so, and had a great chat. He was a retired programmer with several software patents to his name, and had plenty to tell us about — really interesting and very pleasant. He invited to me a youth club at a community centre called E-lok, which hosts a Linux User Group. I said I’d try to go next week. C-base is a very cool venue, it has incredibly designed interior (it has a kind of spaceship theme to it), and it’s the most impressive hackspace I’ve ever seen, but I was not made to feel welcome there as a visitor. It made me think how regulars at Madlab, Manchester Hackspace or any user group I attend — myself included — conduct themselves in this situation — and hoped that others or I did not make any newcomers feel this uncomfortable. User groups are known to have their share of oddities like socially awkward or partially autistic attendees (geeks will be geeks), but I’d like to think the groups I attend are rather welcoming and inclusive. I know a significant number of people at these groups who actively include new people, and know that they avoid making people feel uncomfortable. I will probably be returning to c-base while I’m here, so I hope my next visit proves to be more successful.

The next day I took a trip to Alexanderplatz and had some lunch and a coffee while trying to use the collection of offline maps and Berlin travel apps on my phone to determine where any of the things I wanted to go to or see were located relative to the places I needed to go. I took a walk around the area and ended up wandering in to a big shopping centre where I decided to buy a German SIM card so I could access the internet from anywhere — this proved to be extremely useful. Later that afternoon I headed to Kottbusser Tor to go to a coworking space called Co.up — which was hosting Python Users Berlin (PUB) that evening. As I arrived, the organisers were setting up the room and projector and things, and speaking to each other in German, but as soon as they were ready to start one of them welcomed everyone and announced “We’ll be switching to English now” — it’s a kind of neutral language, the lowest common denominator — Berlin being such a major city, its inhabitants are fairly international, and English is the best know language so that’s what they tend to use. I saw a great talk called ‘Becoming a Better Programmer’ by Harald Armin Massa (aka the ‘Lightning Talk Man’), in which the speaker explained a number of techniques he has studied to tuning your brain to perform better at certain tasks — including personal experiences with various motivational, self discipline, learning and information management techniques. A guy called Andreas announced at the end that he was looking for people to help coach at a Python for Beginners Workshop coming up on the Saturday — I approached him afterwards and offered to go along to help out. The group then retreated to a local restaurant. On the way I thanked the speaker and chatted to him, saying I was visiting from the UK — he said he would see me at PyConUK but I said I was missing it as I would still be in Berlin. At the restaurant I sat next to Andreas and chatted to him about the Python Workshop — it turns out he’s a volunteer for an organisation called OpenTechSchool which runs free tech workshops, and Berlin is just one of their bases. I said we do loads of things like that in Manchester under different names — and that we should collaborate with them, sharing resources and such, maybe get a Manchester OpenTechSchool centre set up.

The waiter took my order (I pointed at an item on the menu while asking for “the beef casserole”) but he brought me a dish of meat in sauce with mashed potato — I said I thought my dish came with dumplings, he said “No, the ox cheek comes with mashed potato” and verified by referring to the menu. Not wanting to cause a fuss, I took the meal and I did enjoy it nonetheless. I had two weissbiers throughout the meal and towards the end, someone asked for half a weissbier — the waiter said it came in bottles so did he want to share one with me — I said I’d be happy to. As people were ready to leave, each one dealt with the waiter and paid their own share individually, and I was the last one left — I reminded him I’d had “the ox cheek and two and a half weissbiers” but he said “actually, three — the other guy only paid for two”. I felt put on the spot and I had a feeling I was being taken for granted — I didn’t know the guy but I’m sure he wouldn’t have left me to pay for his drink, and wondered why the waiter had let him not pay for it. The ox cheek was probably more expensive than the dish I’d ordered too! Feeling responsible for it and, again, not wanting to cause a fuss, I paid, giving him the amount rounded up to the next Euro. He grunted and muttered something under his breath and walked away without leaving me the change. I was later told people don’t leave tips on the table after a meal in Germany, they just give the waiter what they want to pay on top of the bill, so he must have thought I was doing that and only giving him a tiny tip. He’d given me the wrong meal, and made me feel really awkward that I’d been charged for an extra drink, and I really thought he was just ripping me off, and him being rude when taking my money just made it worse. A very odd end to the night!

I then tried to get hold of Sam, as I was staying at his house again, but couldn’t reach him so I texted his housemate James to see if he was at home. He replied to say he was heading out to a party and I was welcome to come. I didn’t really have a choice, but was glad to join him anyway so I caught the U-bahn and met him at another part of town where we went to a bar for a lock-in. We stayed there for a few hours, and James went off somewhere else and gave me his keys — I got on the U-bahn home about 4.30am. I got off where he’d told me to, and checked the map on my phone for where to walk from there — it looked like the best way would be to walk 7 blocks and turn left. After about 7 very long blocks, I hadn’t seen the road I was looking for so I checked my phone again. The blue dot showing my location was on the opposite side of the station — I’d walked the wrong way! And at that moment my phone battery died. I walked back to the station and another 7 blocks, turned left down it and walked for a while, decided it wasn’t right, checked the map on a bus stop, walked further, and kept going back on myself. By about 6.30 I gave up thinking I was realistically in walking distance from the apartment and so I went in to a U-bahn station and tried to plan a route home. I went back and forth a couple of times, trying to get closer, then switched to another line and found my way back around 7am. What a disaster! Also, while in the pub Sam texted me to say the person whose room I was staying in would be returning that morning so could I be up and out of the room by 10am. As I climbed in to bed I put my phone on charge and set my alarm for 10, just three hours away. I got up, exhausted from walking around aimlessly all night and on barely any sleep — and realised I needed to do some work on Pi Weekly as it was due to be sent out at noon that day (BST, so 1pm for me). Luckily I’d arranged for my co-curator Ryan to look after it while I was away, so he’d already collected the links and got it ready to go. I checked the links, layout and wording and all the perfectionist bits I do before finalising each issue, and scheduled it to be sent. Then Sam awoke and said his other housemate wasn’t coming back after all so I could go back to bed. I slept well in to the afternoon! After spending the first two nights with Sam, I then moved on to my accommodation for the rest of the week — an airbnb place Martin had recommended — a lovely couple with a baby, who rent out the spacious spare bedroom in their Kreuzberg apartment.

The next day I returned to Co.up for the OpenTechSchool Python Workshop (Python for Absolute Beginners). We had about 30 people turn up for the workshop — and about 12 coaches. Once we were set up, Andreas briefed the coaches before everyone arrived, and gave an opening presentation when we started. Rather than a led session or lesson, participants were given the URL of a github project guiding them through using the Turtle module in Python — something Andreas had said was a good place to start for beginners as it’s all visual and graphical. Everyone seemed to get along with it well and we were walking around checking people were ok and answering any questions they had. The mix of operating systems, text editors and spoken languages didn’t really bother anyone — we would suggest editors and IDEs if people asked, and pointed out features in ones they were using, but mostly just lent a hand with syntax errors and answered general questions. One guy there asked me if there was any additional material because he’d skipped through it quite fast. I checked with Andreas and he pointed him to the rest of the OpenTechSchool material, and suggested he looked at something like Learn Python The Hard Way. I showed him my Python Intro project and got him started with Python Challenge which he really enjoyed.

On Monday I took a walk from the apartment in Kreuzberg to Checkpoint Charlie, and initially just wandered around the checkpoint to take in what was there. Starbucks, McDonald’s and Domino’s Pizza. I spotted a little food stall called ‘Checkpoint Curry’ and ate a nice currywurst from there. I then entered the museum, which was full of interesting bits of history from the Berlin Wall, the state of culture during the divide, various stories of resistance and people daringly crossing the boarder any way they could, all the events around the fall of the wall and the politics of rebuilding society in Europe.

Next I took a walk to Potsdamer Platz, which was thriving with traffic and is full of huge buildings and massive corporate advertising. It was raining pretty hard at the time too, so I kept walking on. I reached the Holocaust memorial which is a really cool area full of big stone cuboids of all different heights, in a grid. They start low on the edges and get higher towards the centre, so I stepped up on to the first one and walked across them right to the middle, hopping about between each one as it got higher. I took a few pictures from the centre and from the far end, and proceeded to walk further until I reached Brandenburger Tor, the iconic former gate in the city divide. I took a few pictures of the arch before receiving word from Sam that he would be heading to cbase.

I headed off to meet him there. It was the Symphony Stammtisch, a drinks meetup for users of the PHP framework Symphony. Like the Ubuntu event, not a lot was organised for the meeting, and so Sam and I just chatted with a couple of people there for Symphony — one of whom was a woman I’d seen at the Python group the week before, but not had a chance to speak to. I noticed her accent and asked if she was American — to which she replied she “used to be”, but now has German citizenship. The other was a guy who told us about the startup he works for, which sells customisable muesli. We stayed a little while and chatted, before heading off for a kebab.

The following morning I went for breakfast at a place Martin had recommended in Kreuzberg — called East London. It’s a British style café which does a great Full English Breakfast. I stayed in there a while, and did some work on Pi Weekly after eating breakfast and while drinking coffee. Once my battery was drained I returned to my room in the apartment and prepared my presentation for the talk I was due to give that evening. While I was planning my trip, Martin suggested I checked for any user groups that were on during my stay — I found Python Users Berlin and one called Geek2Geek — an event aiming to bring together tech people in different languages and disciplines. I RSVP’d on the meetup page and discussion began on what talks they could have. I said I would be visiting from the UK and would be happy to talk about Raspberry Pi and Raspberry Jams in the UK, which they accepted and invited me to speak. I gave a lightning talk at PHPNW recently, where I just brought up pictures of Raspberry Pi projects and talked briefly about each of them, and gave a similar short talk at Madlab, so the slides used evolved between each of these talks and I used these as a starting point for Geek2Geek. I added some recent projects and expanded on what goes on in Manchester and at Madlab.

I finished preparing in plenty of time and headed out early to make sure I could find the venue. I went to the address which was given to me as Fashion For Home — Showroom im Quartier 208, Behrenstraße 28, 10117 Berlin and I was asked to arrive at 6.30 for a 7pm start. I found the street, and walked down looking for number 28 and something labelled Fashion For Home. I’m not sure what I was expecting but I found a furniture shop called Fashion For Home. I guessed maybe the event was in a room upstairs from the shop, so I wandered around looking for an adjacent door leading to the upstairs offices or something. There were no doors — just shops either side. There was a printed A4 sign on the door in German which said something about it being closed from 7pm. A guy in the shop entrance came out to me and said something in German — I said I was there for an event — he changed to English and said “Geek2Geek”, I said yes, and he said I was a bit early. I said I was told to be there at 6.30 as I was speaking. He said “Oh so are you Ben?” I said yes and he invited me in. I asked where the event would be held — he said “over there” and pointed at the middle of the showroom. Shortly after, other people started to arrive and I introduced myself to each of them, chatting away. One guy turned up and spoke to me and I realised he’d been tweeting me the last few days — he’s an English developer called James who lives in Berlin, and he’s subscribed to Pi Weekly, and he read that I would be speaking so he signed up and came along. I then met another Englishman, also living in Berlin, called Sam Carlisle, who I was told about by a couple of people before I left. He was a member of the London Hackspace and he’s involved in organising and running events called Cryptoparties. We chatted briefly and quickly identified a number of mutual friends and events we’d both attended. We’d both heard about each other from other people.

They started setting up the projector on a bedside cabinet and projected on to a wall in front of a double bed, and aligned various chairs, sofa seats and loungers facing in the direction of the wall. More people arrived, we chatted and I plugged my laptop in to the projector. People sat down, I was introduced and I began. While speaking I constantly reminded myself I was speaking to non-English natives and so kept slowing down and tried to speak clearly. It seemed to be well received and people nodded along, laughed at the right times, looked amazed when I told them about Amy speaking about her Game of Life project at the Jamboree. I was asked a number of questions afterwards, and then Sam stepped up to speak next. I found a lounger at the back of the room and perched to hear what he had to say. Sam gave a brilliant talk on Read/Write Society, explaining hackerspace culture, and the “rules” they live by, such as “repair is better than recycling”. He spoke passionately about the importance of device freedom — expressing despair that companies turn Turing Complete computer systems in to locked down machines that do limited tasks, and explained how you can fix this with various hacks. Much of what Sam said related to the Raspberry Pi, and he praised its success in giving people, particularly young people, the freedom to create things. I chatted with some people afterwards about the Raspberry Pi, Raspberry Jams, the tech scene in Manchester and the UK and all sorts. James was interested in helping attending a Berlin Raspberry Jam — and Sam mentioned wanting to help set one up — so I hope between them and others they can make it happen! Maybe next time I visit Berlin I can attend a Jam. The slides from my talk are available here.

The next morning I was due to check out of my airbnb accommodation, so I packed my bags and started the day by returning to the East London café for breakfast — this time trying their pancakes, which were very nice. I moved on to a café Martin recommended called Sankt Oberholz. Every single table was full of developers working on laptops. I worked on Pi Weekly there for a while before heading off to meet my friend Sophie. Sophie is an Austrian who went to my university and was in my canoe club. She’s now living in Berlin where she teaches English at a school. We met at Alexanderplatz where she introduced me to her boyfriend and we went on to a cocktail bar and restaurant and caught up and exchanged stories. I stayed at their place that night, and I’d booked another airbnb for the next night, for the rest of the week. I arranged to get the keys for that place at noon the next day. Sophie’s is quite far out from the centre, so my route to the new apartment involved four changes on the train and underground. I took the first train, got off and waited for the next connection. After a few minutes I saw a train pull in to an adjacent platform, and realised it was the one I needed, so I jumped up and ran through the underpass to get to the next platform — and managed to hop on before the doors shut. While looking at my app for how many stops I needed to take, I realised I didn’t have my hold-all with me — just my backpack. I realised I’d left it on the platform. I got off the train at the next stop, and hoped there would be another train back the same way soon — and fortunately one came right away. I took it one stop (really hoping it wasn’t a different service taking another route), and hopped off and retrieved my bag from where I’d left it on a seat — phew! Now running late, I waited for the next train and continued my journey, and texted my contact at the accommodation to let him know.

I arrived, collected my key, dropped my bags off and did some clothes washing. Then I went to c-base and spent some time there with Sam (Carlisle). We discussed cryptoparties, crypto in general, PGP, OTR IRC, encryption and privacy. I’d planned to attend a Linux group that evening, as invited by the retired chap from the Ubuntu group on my first night, and when 7.00 came around I left for E-Lok. E-Lok is a youth centre in Warschauer and is the venue for one of the Linux meetups in Berlin — called Linux Works. I had expected it to be a Linux group for young people, but I was mistaken — it was an adult group that just meets at the centre. I sat down and chatted to a couple of people, and spoke to the man who’d invited me — and he asked if I would speak about the tech scene in Manchester, and so I ended up giving a condensed version of my Geek2Geek Raspberry Pi & Manchester Raspberry Jam talk — showing the slides from my laptop display for reference. The talk went down well and everyone was interested in talking to me about its contents. I got in to a discussion with a guy about Ubuntu and Canonical (he was rather anti), choices in window managers, and then about some programming languages — PHP, Python and golang — after he showed me a podcast website he’d written in PHP (which used a huge associative array as its database!) and how he wanted to rewrite it in go. I also spoke to a guy called Paul who works part-time at the FSFE with my friend Sam (Tuke). I then met a woman called Jana, who is a Linux sysadmin and a councillor for the German Pirate Party. She told me of some events coming up at the weekend — Software Freedom Day on Saturday and the Pirate Election Party on Sunday. She also asked if I was going to Oggcamp — which I am — and she said she wants to go. Great to hear people outside the UK know about the event!

The next day, Friday, I decided to head to some tourist attractions and museums — and so took a walk along Torstrasse and turned on to Friedrickstrasse in the direction of Museum Island. I could have taken a more direct route but was in search of food so stuck to the main roads. While walking down Friedrickstrasse, I saw someone I knew — Nicola, a friend from sixth form I haven’t seen for about 6 years! There were very few people about — I was walking down the street and she was standing under shelter from the rain, looking out at the street, and we just caught each other’s gaze and I went over to say hello. She was there for a long weekend with her boyfriend. We chatted for a few minutes, swapped contact details and have since exchanged a few emails. What a coincidence to bump in to each other like that! I continued walking through the rain, and saw some beautiful architecture, huge old buildings, all the time thinking they would look much nicer in better weather. I found Museum Island and discovered most of them, such as the Egyptian Museum, required prior booking. I kept on walking around seeing the sights, along with crowds of tourists in raincoats. I witnessed a number of tourists walking around taking photos with their iPads in light rain. Seriously. I came across a movie set where they were filming — no idea what for but they went round telling people they were “in the way” and could they move on. I walked around some more, disappointed that the sights were not at their best, and I spotted a bus pull up displaying that it was headed for the Zoological Gardens. That was somewhere I intended to go at some point, so I jumped on. Knowing it was too late to get in to the zoo itself, I thought it would be good to check out a different part of the city. I got some food from a noodle shop and wandered around. The zoo closed at 5pm so it wasn’t worth going in, especially not as it was raining anyway. I walked off and went in to a general souvenir shop, where I saw an odd souvenir — a t-shirt with the Android logo “eating” the Brandenburg Gate, with the word ‘Berlin’ underneath. It made no sense, really, but I thought it was funny so I bought one. I wandered around some more and was generally fed up of trying to be a tourist, and of the rain, so I headed home.

I chilled out a bit in my room, and later on received a text from Sam (Tuke) who invited me to go for a drink with him and some Free Software Foundation colleagues and friends so I headed to Wedding and met them at his friends’ apartment and later went to a bar. We stayed out pretty late talking about free software and development. One of the guys said he used to work for a German social network website which at one time was very big and had offers to be bought by Facebook for its user base — the owners refused as the advertising revenue was so big, but it eventually declined in use (losing users to Facebook) and became unprofitable and unfit for sale. I think he said it did get sold, but for a tiny proportion of what they were originally offered, and that even then was a really bad deal for the buyers! He explained how he worked on a recommendation engine for attempting to invite users to groups based on common connections. It was a crazy explanation, but a really interesting one! I quoted him at one point as saying the following:

And then this:

I slept well in to the afternoon the next day, and headed straight to the venue of the Software Freedom Day I had been told about by Jana at E-Lok. I had a few connections to make, followed by a walk, to get there. Fortunately it was a much nicer day. I arrived at IN-Berlin, which is the office of a non-profit ISP, and the home of another Linux User Group called [Be]Lug. The event was just a bunch of Linux geeks (about 12 of us) sitting around a table eating pastries and cakes and drinking coffee. It was good — had some interesting chats with people at what soon became the English end of the table — as I was joined by a student from Istanbul, a 15 year old boy called Reuben (originally from the Isle of Man, been living in Berlin for 5 years) and later, Jana, who offered to give us a tour of the space. They have a really cool setup there, with computer desks, soldering kit workstations, plenty of Linux and free software posters, murals (a weird one of Richard Stallman) and a huge box of Linux washing powder! They also have a lot of cool stuff on display in their windows at the front — which is a great idea to show the public what they do. They have a 3D printer (and some 3D printed objects), some official LibreOffice disc sets, Arduino powered LED displays and such. The guy from Istanbul said he had been in Berlin for 6 months but never been to c-base, so Jana and I said we’d go there next and take him. I told Paul (FSFE) we were going to c-base and he said he’d come too. I arranged to meet Sam (Carlisle) there and so I went to look for him when we arrived. We discussed a few things we’d mentioned briefly previously, including events and initiatives we want to set up and run between us, in Berlin and in the UK. We shared experiences of doing similar things we’ve done before, or know other people who’ve done similar things. We have a lot in common in terms of what we want to do, and how, and experience in being involved in these things. We should hopefully be putting some things on together in the UK next month — watch this space! And we’ve made a foundation for a Berlin Raspberry Jam too. Sam left and so Paul, Jana and I headed to Ostkreuz to get something to eat. Jana walked us round showing us some interesting areas, and we ate at a brilliant grill place. We then proceeded to a bar called Liberacion, where Jana left us and Paul and I had a drink and a chat.

On Sunday I met Sam (Carlisle) at c-base again. I rang the doorbell (a three button mouse) when I arrived and said I was there to meet Sam Carlisle. The guy just said “he’s not here yet” and just stood in front of the entrance giving the impression that I couldn’t come in. I said I’d wait for him and he said ok and shut the door. Ideally I’d have waited inside but apparently this wasn’t an option. I sat on the bench outside and got my laptop out. Sam took a while getting there as he had a few things to do on the way. He apologised for me not being let in. They’re generally not very welcoming, especially to visitors not accompanied by a member. Understandable that they don’t want people wandering in off the street, but they could have easily let me sit in the bar as I was meeting a member there. It’s more the fact they come across as rude and unwelcoming. Anyway, we shared a few ideas and discussed some things, and Sam showed me a button he’d just made with a 3D printer, and he stitched it in to his trousers to repair them — very cool! He’s got some other things he uses daily that have been printed — little things like a handle cable tied to a plastic bottle and a cable tidy. He’s looking at setting up a 3D Copy Shop — a concept whereby people bring in objects, they get scanned in and reprinted. An awesome idea I’m sure will be commonplace at some point in the future — and when we start to see things like that, it’ll be the start of something big! We ordered some pizza and then headed to the Pirate Election Party!

I was surprised to see so many people there — about 300, I think. There was a crowd standing about in an open area with a bar, and some screens and cameras and stuff going on in a room inside. The atmosphere was great — everyone in high spirits, being very social, chatting and getting to know each other. Sam introduced me to some friends of his he spotted when we walked in, and people were saying they were disappointed by the exit polls saying they only had about 2% of the vote. At the time it looked like they hadn’t really made any progress and that Merkel would more than likely win, but possibly not reach a majority. Despite this, everyone enjoyed themselves and we got to chat to some interesting people. Sam (Tuke) and Paul from FSFE turned up later on too. I was in the room with the big screen when a result came through and the room erupted with joy — I’m not quite sure what exactly was being announced, maybe it was the local result — but it said the Pirates got 2.5% and 2.0%. Discussion that night ranged from tech chat to piracy, privacy and encryption, Snowden and the NSA, and general German politics. A real mix of people there — anarchists, punks, rockers, hippies, techies and more. Some discussions we were involved in were very odd, others quite interesting and thought provoking. It was quite exhausting! We went off for a kebab at one point, returned for another beer and left around 11pm.

On Monday I went to the FSFE office to meet Sam (Tuke) and went for lunch with him and his colleagues. We ate at a place called White Trash and had some nice soup and salad and a rather disappointing burger. Then I decided to take up a recommendation from my friend Tim, which was also backed by Sam — the Alternative Berlin Tour. I went along not knowing what it would be like and ended up really enjoying it! Our guide, Lynn — a girl from Luxembourg who studied in Berlin four years ago and “fell in love” with the city and decided to stay — showed us around parts of the city you’d probably not otherwise go to. First up, we stopped at an old railway bridge covered in graffiti — she asked if we thought graffiti was legal in Berlin — it isn’t! But enforcement of this ruling is very minimal, and fines are small, depending on the type. If it’s spray painted tags on a corporate building, that’s pretty bad, but a lot of what you see is things like paste-ups (printed pictures pasted and stuck to walls) which are quick and easy to put up, and time can be spent working on them from home, so people rarely get caught doing this sort of thing, and these fines are minimal anyway. There are also spray stencils which are also quick to apply, and are reproducible. Lynn pointed out some of the artwork and explained the themes behind them — many of which are really interesting! One artist has a theme of work involving a picture of a girl labelled Little Lucy and pastes a picture of a dead cat somewhere nearby — the game is to find the cat once you’ve seen Lucy. She’s usually holding a gun or other clue as to how she killed the cat — and the cat may be shown with a hole in its chest (as if it’s been shot) or just hung from a lamppost or something. Another artist by the name El Pocho draws pictures of women who have fallen in love with Berlin, and each of these women is accompanied by a phrase like “I see him but he doesn’t see me” or “Goodbye Childhood” which indicates she is growing up and so is Berlin, and that things are changing. Another theme is a series of pasted characters in various work outfits — a bus driver, a businessman, a clown — shown wearing a gas mask — all with the caption “soon”, as if to suggest pollution will one day mean we will go about our daily lives as normal but be forced to wear gas masks. A really intriguing one is a series of paste-ups — this would be difficult to decipher its meaning without being told — which consists only of poor quality black and white photographs of people just standing about doing nothing in particular. Lynn explained that these are of people as they can be seen on Google Street View in those respective locations. An artist ironically known as Sober just pastes up pictures of drunk women dancing. There are lots of pieces of art, or just written slogans that simply express political messages or ideals — many regarding the Berlin Wall (such as “The next wall to fall — Wall Street”), class divides and often some expressing dismissal of Nazism saying it’s not welcome. There’s also a retired man who goes around painting the number 6 everywhere, in no particularly artistic fashion and without making any statement. Lynn explained that he has been asked about this and in interviews with magazines he’s said he’s doing it to make the internet go faster! Something to do with 6 in German being “sechs”, pronounced like “sex”. And the internet is full of sex. Makes sense. We then hopped on the S-bahn and Lynn pointed out the East Wall Gallery — a collection of artwork on the remaining parts of the Berlin Wall. We didn’t stay to look at it, but I made a mental note to return the next day to take a walk along the wall. Instead we checked out YAAM — the Young African Art Market, which is an afro-Caribbean style area full of sand, deck chairs, hammocks, beach football pitches, ping pong tables, and is full of interesting art projects. It lies in what was once “No Man’s Land” between the wall and the river. The slogan “YAAM must survive” was repeated in many places — this is a reference to the “Media Spree” which is an initiative to make use the land around the wall for big corporate enterprises. They’ve already built big office blocks, a sports stadium and all sorts on this land, all plastered in huge advertising and corporate logos. There are many slogans painted around the area, such as “Fuck off Media Spree”. Unfortunately YAAM has already been sold off to be used for the same purpose, so the messages are now in vein.

We then took a walk over the river and she pointed out a house that belonged to a Turkish man during the divided city years, who built things in and around his house out of other people’s trash — including a tree house. The council thought he might be masking a tunnelling attempt with the tree house and such, and so ordered an inspection of his property. It turned out he was just building a tree house and nothing more. Once he was ordered to move, and he refused, and concreted all the furniture in and around his house to the floor! He now lives in a new apartment across the road from there during the Winter, and moves back in to his makeshift house in the Summer — he’s in his 90s. Walking further, we entered Kreuzberg and she showed us a piece of artwork on the side of a building — a giant stencil of an astronaut in black ink. The stencil was done by cutting a sketchbook picture up in to a grid and making stencils for each piece of the grid. By itself it’s a great mural, but Lynn also pointed out that at night, a flag can be seen waving on the wall too — which she left us to ponder for a minute before revealing that there was a floodlight across the road and some flags up around a car showroom — which were there before the picture — and the artist chose to do an astronaut here knowing that the flag would present itself alongside. The tour ended here and people donated generously (it was a free tour on a donate-what-you-want basis) as everyone enjoyed it so much. That evening I returned to co.up for the Continuous learning in Python session put on by OpenTechSchool. The young boy from the Isle of Man, Reuben, showed up and I worked with him on a Turtle exercise in Python. I later returned to the Astronaut picture in the dark to witness the flag appearance — very cool indeed!

Tuesday was my last full day in Berlin — I revisited the East Wall Gallery and walked all the way along it, taking pictures of the more interesting paintings. Unfortunately it was raining so wasn’t too pleasant to be walking around — much like the other days I’d attempted to do tourist things! I ended up walking in to Kreuzberg again and finding a cafe to retreat to. I stayed there for the afternoon and arranged to meet Sam (Tuke) that evening. We went to a restaurant that evening for German food — as I hadn’t really had any yet! Just kebabs, chinese and such! Had a great meal, and some interesting discussion about free software and licenses (amongst other things) and headed home. I stayed with Sam again that night and left early for the airport. This time I arrived over 2 hours early for the flight — and was turned away when trying to check in my luggage before the luggage desk was open for my flight. I went for a coffee, checked my bag in and proceeded through security and eventually to the gate in plenty of time. Much less stressful than the journey two weeks prior! Lesson learned.

In summary, I had a brilliant time in Berlin. It was a really relaxing holiday and I got to meet some great people, have really interesting conversations and see what life in Berlin is like. I’ll definitely return at some point!

When I got back I managed to bundle a Raspberry Pi in with my clothes in the washing machine. But luckily after drying it out in rice for 2 days, it booted successfully! Phew!

STEM Raspberry Jam Pilot

I organised an event with the STEMNET (Science, Technology, Engineering & Maths Network) team at the Museum of Science and Industry (MOSI), based on the Manchester Raspberry Jam I run monthly at Madlab. The STEM Raspberry Jam was to be a new activity the STEM Ambassador network could offer to schools, so we ran a pilot (pi-lot) to give the idea a whirl.

MOSI supported the event and kindly offered to host it at their fantastic venue in the museum on Liverpool Road off Deansgate in Manchester, and the STEM team had invested in ten Raspberry Pi kits (Pi, SD card, VGA converter, power cable & PiFace) which they intend to loan out to ambassadors running Raspberry Pi activities! We invited a number of schools to the Jam, and awaited their response.

I was given the ten SD cards and asked to add the software we’d need to them. I imagined this would take forever but it was actually rather rapid – I initially wrote the standard Raspbian image with PiFace pre-installed to the first card using dd, booted it up on my Pi, set the raspi-config settings to enable ssh, boot to desktop, correct timezone, etc. I then updated apt and installed a few essential packages and python modules. I then ran the dd command in reverse (switching input file to the SD card, and output file to a new file on my machine: stem.img) – this copied the image from the SD card to my computer, in the state I had left it. I was then able to run the dd command again, this time writing stem.img to the blank card. I tested each one by simply booting it to desktop, with no problems whatsoever!

We set a schedule for the day which included introductions, a morning session playing with Scratch and the PiFace, followed by an afternoon in Python. We had some Scratch and PiFace activities prepared, complete with booklets and instructional step-by-step guides. I’d written some Python activities for the kids to work through in the afternoon. With more time I’d have written these as part of the image I wrote to the cards but I wanted to make sure the cards worked ASAP, so I had to add the files on the day. Luckily this wasn’t difficult either – I just inserted the card in my laptop, one by one, and copied the files to the user’s home directory when it came up as an inserted drive, like a USB stick would!

Six schools responded saying they would attend, bringing six pupils each. On the day, we started with a welcoming word from Donna, the STEM Development Manager, (in her best teacher’s voice!) followed by an intro talk from me (in my normal voice). I explained what the Raspberry Pi is, what happens at a Raspberry Jam and why it’s all important (“Raspberry Why?“). I showed some pictures of the Manchester Raspberry Jam, and other Jams around the world. I explained what Scratch and Python are, and talked about the general perspective of “geeks” and compared this to real world geeks – now popular figures such as Mark Zuckerberg! I talked about singer donating £500,000 to improve STEM education in the UK, and how he’s now learning to code!

Raspberry Why?


Then we kicked off with some Scratch and PiFace – we handed out the booklets and let the groups choose an activity based on their interests and abilities. With a group of STEM ambassadors on hand, as well as their teachers, there was plenty of guidance available so they weren’t left stuck for what to do. It was great to see the kids building things in Scratch – some following examples by the letter, others just experimenting and exploring! I’ve not really used Scratch myself, but I am amazed to see it in use – some really cool things happening on screens everywhere you look – animations, controlled characters, games, interaction with real world hardware – really awesome how they just got on with it.

We stopped for lunch and I chatted with some of the kids and teachers about what they were doing in school – mostly just dull ICT stuff with Word and PowerPoint, a bit of Scratch and (eugh…) Dreamweaver. However some of them seemed more excited about Code Club being run after school – so that’s something!


For the afternoon session we moved on to the Python activities I’d written late the previous night! To start, I gave them – a single Python file containing a linear set of tasks, each explained in comments in the code. It was just an idea I’d had the night before, as an easy way for me to make sure they covered all the fundamentals to move on to tackling some interesting problems. This activity went down really well and lasted the whole afternoon session! All twelve groups (three kids per Pi) attempted to work their way through it – with ambassadors on hand to help out with syntax errors and general clarification, it went rather smoothly and as I wandered around the room I saw amazing progress! The script covered printing, variable assignment, basic data types, lists, if statements, loops and so on. You could see them working through the challenges and understanding the concepts.

A few of the teachers (and kids) asked if they could take a copy of the code, or download it from somewhere. I let anyone with a USB stick take a copy, and promised to publish it on github. I knew it needed some work to be at a decent standard but it had been a really good exercise that day and fulfilled its purpose. We wrapped up the day by asking groups to raise their hands if they got past the first level, then proceeded to raise the bar and see how far everyone had got – every group had got to around Level 16, and one had reached the very last challenge, Level 22! (I’d purposely made this one fairly complex)

I uploaded the files to the MadlabU18 Github account, and it immediately had a couple of contributions from my partners from Coder Dojo! I’ve since been considering options for the project’s future. This week I ran a session at the Python North West User Group, where we each paired up and attempted to build a more sophisticated automated learning tool (similar to the Python Koans, but for kids). From that session I’ve had a few more ideas about how it can work. Well, watch this space.

STEM Raspberry Jam

Huge thanks to MOSI, STEMNET, Donna, Dan, and all the ambassadors who volunteered their time and effort to make this happen – Arran Gallagher, Graham Nelmes, Etinosa Ogiesoba, Amin Hoque, Joe Haig, Erinma Ochu, James Burnstone, Lisa Mather and Dan Mather.

Raspberry Jamboree 2013

Manchester recently held the first ever Raspberry Pi conference – Raspberry Jamboree, held at Manchester Central. It’s been a year since the launch of the Pi, and this event was to review what we did in the last year, and look forward to what we’re going to do this year and in the future.

The day kicked off at 10.30 with an opening talk from organiser Alan O’Donahoe, followed by a wonderful keynote from BBC Micro pioneer Steve Furber. The first session of talks featured Andrew Robinson (creator of PiFace), Carrie Anne Philbin (from Geek Gurl Diaries) and CERN‘s William Bell (talking about MagPi). Meanwhile, in another conference track, a hands-on workshop was being led by Mike Hewitson (LateRooms) and Pete Lomas (Raspberry Pi Foundation).

Up next was a panel discussion with Raspberry Jam organisers and attendees – including Lisa Mather, Dawn Hewitson, Ben Smith, Jack Wearden and myself. We introduced ourselves and discussed what Jams are, how they work and what we think about them, and answered questions from the audience:

One of the things that came out of this was when asked where teachers and Jam organisers could get material from to teach coding or run activities, the panel suggested using existing online resources like Codecademy and asking for help on Twitter, and I said that between the community we should strive to make resources available for this kind of use. I suggested anyone interested get together with me to discuss creating a central repository for programming tools and exercises for the classroom, code clubs or for personal skills development – using GitHub as an example platform for how this could feasibly happen and have contributions of new projects and improvements of existing ones, and making it easy for teachers to download and use. Since the Jamboree I’ve been in talks with a few people regarding this. All I can say right now is watch this space – or, better – email me your thoughts if you’re interested.

After lunch I got to see Raspberry Pi Foundation evangelist Rob Bishop speak about what’s going on with them, which was fantastic. He’s a wonderful enthusiastic speaker and I really felt the energy of what this is all for. I got a bit carried away with this tweet:

Next up was Paul Hallet, whose project DjangoPi had caught my attention when it was announced last year. That’s one of the great thing about the Jamboree – we’d all heard of all these names but never met most of them, so it was amazing to have everyone all together in one room where you could put names to faces, shake a few hands and pat people on the back! Paul’s talk was on crowdsource funding for projects, and he went over the story of his projects such as DjangoPi and the coding club he ran in a local school. Great going for an undergraduate student! He already has a fantastic CV!

Following Rob and Paul was one of the Manchester Raspberry Jam regulars – a 13 year old who goes by the alias ‘Mini Girl Geek’. Amy Mather was asked to present a project she and I started at a Jam in December – Conway’s Game of Life. What began as a simple Python programming exercise turned in to a really interesting project involving pygame, Raspberry Pi, Arduino and an LED matrix display! Amy’s talk was extremely well received, she was praised by all and congratulated personally by the likes of Paul Beech, Rob Bishop and Pete Lomas! As one of the adults who has guided her along the way, I’m very proud of her for giving this talk and can say she did so professionally – a thoroughly enjoyable talk. Now watch it!

It’s since been featured on the Raspberry Pi blog and in the Pycoders Weekly newsletter!

A closing address from Alan rounded things up and a few of us headed to the nearby Pizza Express. After a mishap with their machine not accepting my (perfectly valid) card, Alan pulled a few strings and persuaded them to accept slightly less cash than than the value of the meal, we hastily moved on. Most of the group headed home but a few of us stayed out and proceeded to Brewdog where we later met up with Rob, Paul, Carrie Anne, Simon and Andrew and the others. We had a great night getting better acquainted with each other – as I said, many of us knew each other by online personalities only so it was interesting to speak in person for a change. We also dished out a few dozen Raspberry Pi coasters around the bar. I had a fantastic day and really enjoyed socialising in the evening. I tweeted this the following morning:

Thanks to Alan for organising the event, to Les & team for their work on getting the videos recorded (and live streamed!), to all speakers and attendees and to the sponsors for making the event possible – CPC, Bytemark, BCS Manchester, Frogtrade, OCR & PC Pro.
