Chantal and Kenneth talk to Grant Ongers and Mike Davis about infosec and the local BSides conference in Cape Town. Grant and Mike are part of the organizing team behind BSides in Cape Town, and both love working in the infosec space. BSides here is based on, and supported by, the BSides conference in Las Vegas. BSides originated as a community event in Las Vegas and has been running for many years. It happens close to the popular Defcon conference. BSides CT is looking to be a great event, with some amazing hardware badges on offer and the opportunity for attendees to contribute to their Rite of Passage program and help a young budding infosec person visit Defcon & BSides LV. We also scratch the surface of infosec and it means for developers in our day-to-day work. We learned a lot, and this is only the beginning!

We chat to Louise Perold about testing as a means to improve the overall quality of software, and the upcoming Let's Test conference Kenneth & Len chat to Louise Perold about the art & practice of software testing. Louise reframes testing in a wonderful light, and how testers compliment and support the existing software development efforts. There are many things that simply cannot be tested reliably with automated techniques, and we explore why. Louise has been helping teams write better software since the early 2000's, and is continuing on that journey today with her new consultancy and yearly conference. Louise is one of the proud members of [House of Test](https://www.houseoftest.rocks/en/), along with [Oz Chihwayi](/51). Louise is also one of the organisers of the local [Let's Test](http://lets-test.com/?page_id=5283) conference. Just a few of the tips offered by Louise for developers working with testers: * Talk, talk, talk * Testers can help clarify your thoughts on design, and help identify where the risks can be * Don't give a checklist of instructions, those are the tests that can be automated Louise definitely gave us a lot to think about, and we hope you feel the same way after the show.

We chat to Inez, Ridhwana & Lara about the Ladies that UX communities in Cape Town, and as of today Johannesburg. Chantal, Kenneth & Kevin are joined by the dynamic trio of Inez Patel, Ridhwana Khan & Lara Pietersen to talk about UX and the local Ladies that UX meetups in Cape Town and now Johannesburg. User Experience (UX) is an integral part of design, be it in the physical world or the digital world. It is the practice of putting the user first, creating empathy for the users of your systems. "If the user can't use it, it doesn't work" -- Susan Dray Lizzie Dyson and Georgie Bottomley, both UX (User Experience) professionals, loved their jobs but there was always a doubt about where the other women in the industry were. So they started the first Ladies that UX meetup in Manchester, UK, and it exploded. Lara was looking for an international community to connect with when she discovered Ladies that UX and it _stuck_. The Cape Town LTUX meetup is the first African chapter of LTUX, started by Lara. Inez and co-organizer Ridhwana launched the Johannesburg chapter of Ladies that UX on the 31st of August 2017. We hear from Inez, Ridhwana & Lara about their general experiences as women in tech, and why community events are so important to support each other. With Ladies that UX having over 50 chapters around the world, it gives also enables them and other community members to connect with each other. Both events focus on creating a safe and inclusive space for woman in the UX field to connect, share & learn from each other. Each event follows a slightly format, from lean coffee and/or cocktails to workshops and presentations. We also chat to Ridhwana about her upcoming TechWomen trip to the US, and how she'll use her that LTUX connections to meet inspiring women over there, and then bring all her learning back to share with the LTUX community back here. We wish her all the best with her journey! In close we ask each guest to relate with us some advice for incorporating UX into our work. The suggestions are great, go have a listen.

We chat to Jade Abbott from Retro Rabbit about artificial intelligence, broadly and more specifically about NLP and what that means for us. Chantal, Kenneth & Len talk to Jade about natural language processing, commonly referred to as NLP. What does it take to get a machine to understand what we're saying as people? Jade has always had a fascination with smart machines, from trying to build robots in school and now teaching machines to understand what we're saying. Jade takes a fairly complex topic and helps us come to terms with it. We question whether people, or intelligence, is algorithmic and what that means. Processing natural language is not without challenges and Jade walks us through the maze of terminology and some tools to get started with, and we have several resources below to help as well. What would happen if AI tries to right a movie? What happens if the movie was made? Importantly, neural nets are not the whole of AI. We wander around expert systems, random forests, and other great statistical models that very useful and predictable. Is intelligence just an algorithm? What do you think? Let us know!

We talk to Ruddy Riba about her career as a women in tech, and Pink-IT and what they are doing to help women in tech find a supportive community and grow their networks. Chantal, Kenneth & Len talk to Ruddy about some of the challenges woman in technology face, and what she and her partners in Pink-IT are doing to help get women into tech. Ruddy shares with us the story of growing up far from Johannesburg, getting into university and seeing the immense drop-off rate of young women in just the first few classes at university. Entering her first job as the only female on the team, it became clear to Ruddy that this disparity needs to be addressed. Pink-IT is an organization that strives to connect women in tech with mentors they can look up to as they grow into the industry. She's also helped high-school students, especially girls, realize that software development is a viable career choice when they didn't even know it existed. Right there at high-school level Ruddy is taking actions that will help address the gender difference in our industry. Ruddy gives us a ton of great information and actionable insights on what we all can do to address the gender equality issues in our industry. One very powerful point is that of intentional mentorship, intentionally helping a female developer grow. Support Ruddy and her work with Pink-IT and their related organizations to foster and grow an inclusive environment that we'll all benefit from in the end.

We talk to Clarice Bouwer about imposter syndrome, what it is and how to overcome it. Join us as we learn about this and other issues around the often overlooked topics of mental well-being. Chantal & Kenneth talk to Clarice Bouwer. Clarice started the Corporate Programmer blog as a survival guide for her work in a big corporate environment, and has written over 50 great posts. It turns out surviving in a big corporate is all out people & relationships! Inspired by Scott Hanselman's "I'm a phony. Are you?" post, Clarice wrote up her own experiences with feeling like an imposter. This well written post landed her interviews on two other podcasts, ours, and the Reddit front page. Clarice also gave a presentation at Rubyfuza 2017 and a recent Jozi.rb. This post and other well researched posts on her blog focuses a lot on how important mental health & well-being is and shares a lot things we can do to look after ourselves.

We talk to Gail Shaw about data, in all its shapes and sizes. Gail is a 10 year Microsoft MVP, and has tamed many a database in her career and shares some great insights with us. Chantal, Kenneth & Len talk data with Gail Shaw. From Gail's first 8086 PC, dual majoring in physics & computer science and printed Oracle error codes we join Gail on her journey into the realm SQL Server and how she's conquered it. We get some advice for squeezing a little more performance out of your production database, which might be more obvious than you'd think! Ever wondered about SQL Server on Linux? Gail has some great insights as to why Microsoft might gone down that route. We all take stock of Microsoft's great recent contributions to the open-source, and the efforts to liberate their tools from their operating systems. We venture into the world of big data, cautiously, while clarifying some terms and distinguishing big data from just "a lot of data". Thinking of big data in terms of analytics help focus the discussions and breaks big data up into layers. The consequences of incorrect medical diagnostics even came up!

We talk to Tim Haak about playing with wifi networks covering large parts of Gauteng, and running Docker in production, and how to sanely get started with conquering containers. Kenneth & Kevin chat to Tim about Docker, what it is, how its evolving and how to sanely start packaging your apps in containers for shipping. Heads up! There were some audio syncing issues during post production, but the content is still great! Also, this show was recorded in 2016 and the content held up quite nicely! Containers & Docker are revolutionizing how software gets deployed, and how distributed systems are being built. As you'll learn, Tim has extensive experience deploying more than just rudimentary bits of software. His involvement with the Pretoria WUG and building ISP infrastructure definitely put him in a good position to grapple with and conquer the Docker story. Tim has plenty of insights of using this fairly new technology that you can learn from.

We talk to Lance Gleason of Polyglot Programming about the software, embeddable devices, biltong and how the local community stacks up against the rest of the world. Chantal, Kenneth & Kevin chat to Lance about his involvement with the South African tech community. Based in Atlanta, Georgia, Lance has definitely made a name for himself in various local communities as a very involved member and connector. It was thanks to Lance that we met and invited Rebecca Franks for [episode 39](/39/), and Mandla and Theo for [episode 36](/36/). From gaming on a Commodore VIC-20 to building software for a family business to working at Kodak on satellite imaging system, to digitizing the vast media archives of CNN/Turner, Lance has had a storied career so far and leaves a great impression wherever he goes. Lance adopted a polyglot programming approach as a means to go to conferences and tap into communities. Lance gave his first ever conference talk in Cape Town at Rubyfuza 2010. Lance is also on the organizing committee for Rubyfuza, and support the yearly Ruby DCamp event that happens outside Nelspruit in the spring. Lance has also done the hard work of identifying the best biltong in the country, but you'll have to listen to find out where exactly. Lately Lance has been working with embeddable and wearable technologies and has some very interesting thoughts on the challenges faced in the field including a few things you might not think off initially. From fitness and mindfulness to medical, industrial and other applications. We wrap up the conversation reflecting on how our local talent compares against other communities overseas. Lance's perspective from having traveled from tech community to tech community is great and supportive and wants us to shine bright on the international stage.

From the importance of pet projects to organizing conferences, come join us as we learn a metric ton from a friend of many developers. Chantal, Kenneth, Kevin & Len are joined by Simon Stewart for a journey through his career as a developer. Simon is a respected and loved figure in many tech communities and arguably best known for organizing the fantastic [JSinSA](http://jsinsa.com) conference. How did Simon get here? We start at beginning in Cape Town, travel to Port Elizabeth, jump to Durban and finally land in Johannesburg where Simon lives to this day. We learned that PE is the birth place of another conference organizer too! We play with a ZX spectrum, tell tales of surviving classic ASP and dabble in some Delphi along the way. Simon has a love for community and we explore what inspired JSinSA and what has kept it running for the past 6 years. We chat about presenting at conferences and Simon shares some fantastic tips for speakers of all levels to build their way up to speaking at conferences. We explore issues around diversity and aging and ways to get communities to cross pollinate, and the importance of participating in community events. We also learn about the importance of pet projects as a great way to learn and sharpen your skills, and Simon shares some of his that he has actually shipped and maintained over time.

What can we teach machines? And what can they teach us? Chantal, Kenneth & Len are joined by Guillaume Belrose to chat broadly about machine learning. Guillaume is currently living in Johannesburg, but hails from the Caribbean. After having studied in France he went onto an internship at HP in Bristol, before moving to Durban and finally up to the city of gold. Guillaume is very involved in the community, being a regular attendee at meetups and having presented at local conferences like Devconf and Tech4Africa. We had a great time meandering through the field of machine learning, talking about everything from machines learning to play games (and win), to how big companies like Google apply machine learning to their data centers to save millions of dollars in cooling expenses to interesting medical applications. Guillaume also offered Kenneth some tips for getting started, including some great online courses to follow. He even gave some examples of practical tools that could be built to help us in our day jobs! We also round it out with a mention of how TensorFlow is being used in farming!

Join us for a walk down memory lane as we retrace the start of the Ruby community in Johannesburg and end up on the trails of the Aosta Valley. Kenneth & Kevin chat with Armand du Plessis, a long-time Rubyist about his journey from classic ASP to being the CTO of Hornet. We get a small glimpse into life before .net and building applications for Symbian, and a whirlwind tour of building various systems in the mobile money space. Armand has always been a keen early adopter, building an OpenID bridge for Facebook (a precursor to their own Facebook Connect platform), hooking up Erlang and Ruby processes with BERT and running Tokyo Cabinet back in the day. His adventures included a brief stop with open-sourced S60 browser from Nokia, trying to bridge native API's and JavaScript long before it was cool! We also have some good chats about the early days of the Ruby community in Johannesburg, the start of then Ruby on Beer (now Jozi.rb) and some interesting visitors we've had. We also touch on BarCampJozi and the need for another one. The last five years Armand has been involved with Hornet, a gay social network and dating app. Armand was part of the team that helped launch the service after just 2 months of build, and made it in time for various launch parties they had all over the world. Admittedly they still have some technical debt today for some of the shortcuts taken back then. Kenneth was very grateful to hear someone admit this openly and honestly. We also lean a few interesting things about their stack and the huge amounts of traffic they do (their CDN serves more traffic than the Cape Town Internet Exchange!). Finally we lace up as Armand shares with us his trail running adventures from the last few years. Armand has embarked on some truly epic runs all over the world, including Mont Blanc, Patagonia, Andora and many more. As we recorded he was getting ready to participate in the 2016 Tor Des Giants. Armand shares some tips and motivation and technology that can help kickstart a healthy trail running addiction.

In this age of containers and virtualization, are we losing touch with hardware and the raw performance available to us? Kenneth chats to Kevin & Len about our current understanding of hardware performance and if it matters in this age of containers and virtualization. Spawned by an article on Non-uniform Memory Access in modern multi-CPU architectures, Kenneth realizes that it has been years since he racked up a server or cared about the bare metal at all. How disconnected has he become in the quest for only dealing with servers through API's?

Thinking of a bootcamp as "a series of long conversations" and other gems from teaching software craftsmanship. Kenneth & Len are joined by Mike Hewitson for a talk on the developer bootcamps that Mike helps to facilitate at Investec. Mike shares with us his journey from the army, to the railways, and how he got onto the financial services line. He has had several stops along the way in various insurers and supporting businesses, with some great stories from each stop along the way. One of the moments Mike is most proud of is being part of a team that got asked by business to "slow down a bit", since they were delivering their software consistently quicker than business expected (or could manage). These were the days before "feature flags" were formalized, and nightly builds and deployments were hair raising. Mike's current stop is at Investec, and this is where Mike helped institutionalize their culture of brown bag sessions into a more structured bootcamp format. These bootcamps run concurrently, with each group being about 10 developers, and they carry on for 8 months! We unpack what the students do during their bootcamp, the support they receive from the leadership in the group, and get a few tips and tricks to get started with our own bootcamps.

We reach over the proverbial cubicle wall and chat with the testers! Kenneth, Kevin & Len are joined by Janco Wolmarans and Oz Chihwayi to talk about their experiences of having software testers integrated into a multi-functional software delivery team. Oz shares with us how he went from running batch processes during the graveyard shift to become a software tester and a key member of his team. Janco tells us the most difficult thing he's done in his career is choose a title on LinkedIn! The idea for the show came about after Kenneth saw Janco & Oz give a talk at the DeveloperUG meetup. They've since taken this talk to Let's Test 2016 in Sweden, along with "vim for testers" and a workshop on flow. We talk about they formed such an integrated team, a team where the developers and testers have daily mob programming sessions. We also clarify the difference between automated software testing, or checking, and the roles of software testers in the team. The result is many lessons from a tightly integrated team, where everyone shares in the responsibilities and rewards of delivering solutions, even if some solutions never involve writing a single line of code.

We turn 50! Frolicking (verb) - to gambol merrily; to play in a frisky, light-spirited manner. From the Dutch, vrolijk. Kenneth, Kevin & Len are joined by former panelists Steven McDonald and Pieter Germishuys for a look back at the origin of the podcast, the past 50 episodes and the future of our founding team. From the humble beginnings of just "recording our frequent Skype calls", Steven & Pieter recount the early days of the podcast and the pain of recording Skype calls. Each panelist shared their favourite shows, and Steven asked which shows were the most challenging for all of us. Steven will be moving to New Zealand in the near future with his family, and we unpacked a bit of what that meant for him. What was the allure, what is he looking forward to and what will he miss? Pieter and his family are off to the UK as well, and we find out about their plans to travel from there. Thanks to Steven and Pieter for starting all of us on this adventure!

What poor development practices get under your skin? In the episode Kenneth, Kevin & Len unpack a few poor software development practices that they've seen over and over again. More or less in order they tackled long-lived branches in version control, having too many automated tests, being too reliant on your IDE, copying the first answer from StackOverflow and not questioning enough. Each topic yielded some interesting insights and counterpoints! We hope you enjoy the episode and would love to know what you thought.

What happens when your database is part of your application? Kenneth & Len are joined once again by Robert Stuttaford from Cognician to talk about Datomic. According to the Datomic website, Datomic is a distributed database designed to enable scalable, flexible and intelligent applications, running on next-generation cloud architectures. Robert shares with us how Datomic became a natural choice for them after switch to Clojure. Before Clojure, ClojureScript and Datomic their site was written in PHP and backed by MySQL. Choosing Datomic was very natural since they've already subscribed to Rich Hickey's "simple vs easy" mindset. Its immutable nature is a great fit for Clojure, and by following an "append-only" storage model they got loads of benefits. We discuss a wide variety of concepts, including how Datomic models data, the different ways it can be stored, how transactions work, the ability to travel back in time to see what your data looked like, and so much more. We were happy to learn that Datomic is accessible to everyone on the JVM, so learning Clojure isn't an initial requirement, but learning some Clojure will go a long way in informing your usage of Datomic. We would encourage everyone to experiment with Datomic and enjoy this different, flexible approach to modeling data.

Join us for a tale of conquering software development as we follow one young star on his journey to taming React. Tonight Kenneth, Kevin & Len are joined by Taariq Isaacs to talk about his journey as a software developer and how he tamed React. Taariq started off his journey at CPUT in their Mechatronics course, a branch of electrical engineering. Not satisfied he started teaching himself through Code Academy and quickly started at codeX where he discovered the joys of programming. One of the early game changers for Taariq was breaking out of the theoretical realm and getting his hands dirty. This was the turning point at codeX. From humble beginnings with JavaScript, HTML & CSS, Taariq dabbled with Ruby & Python too before getting exposed to React at his first job. He shares how he learned to delete code, and how frequently he had to relearn a concept shortly after having learned it the first time. Not giving up Taariq went on to all in love with React and its accompanying technologies like flux (then) and redux now. He's constantly looking to experiment with new tools and practices in the React ecosystem. Earlier this year he delivered his first public presentation at the Cape Town Frontend Developers meetup to a crowd of 40+ developers, and he admitted to having fun :) The journey is great, and far from over for Taariq! He has big dreams of running his own development shop one day, and he definitely has the ambition to pull it off! We hope you enjoy this show as much as we did recording it.

We're joined again by Rishal Hurbans to chat about his Prolific Idea initiative, how it came to be, what it currently does and where it's going. We talk about the X-Prize Learning Challenge and the importance of letting kids learn while they're having fun. Kevin and Kenneth reminisce about Sesame Street, Cartoon Network and learning numeracy in computer labs in primary school. Participating in the X-Prize was what lead Rishal to formalise Prolific Idea into a business. The weekly Code Offs that Rishal hosts have been a great success as a learning tool. We talk and walk through how that came about and how he gets his ideas for the challenge, including detecting gravitational waves! You'll have to go see for yourself in the 13th Code Off. We turned our focus to design thinking towards the end of the show, which turned out to be a much bigger topic than Kenneth thought. It encompasses collaboration and good communication to successfully communicate and execute on an idea. Inspired by modern minds like Elon Musk, this definitely looks like a field to keep up with. A lot of ground was covered in the episode and we look forward to seeing where Rishal takes Prolific Idea, and we hope you're left motivated to participate or execute on your own ideas!

Join us as we look into our crystal ball to see what is coming in the next major release of the popular Angular framework. Kenneth & Len are joined by Mike Geyser from BBD to talk about the upcoming Angular 2 release. Mike has been a web developer for many years, having uploaded websites to Geocities back in the day! The web has changed a lot since the good old days of "single page websites" and "under construction" GIF's, and in this show we look at Angular 2. This major new version has stirred a lot of controversy since it was announced in 2014, with fears around the new tooling, the initial lack of an upgrade path and the adoption of TypeScript as the default language for writing in. Headline features include writing isomorphic applications, easier "native" mobile apps and greater performance than its predecessor. Mike does a great job of showing us what is coming down the pipe.

Taking a hard look at accessibility and learning about the principles of inclusive design. Kenneth & Len are joined by Steve Barnett and Justin Slack to talk about building accessible frontends. We quickly learn that building an accessible website doesn't always mean catering for people with permanent disabilities. We learn about inclusive design as well, thinking about temporary impedances to using websites, color blindness and even catering for slow internet connections and HTML email. Steve & Justin both have considerable experience building websites and they share a goal of promoting and standardizing the practice of building accessible frontends, just like we've defaulted to building responsive interfaces. They recently hosted the only Global Accessibility Awareness Day on the continent in Cape Town where they helped the participants get to grip with what it takes to make an accessible website. Best of all, it is significantly less work than anyone thought. Hope you enjoy the show!

We're having another chat about computing education in the country, this time with a special guest from Durban who is looking to help change the country for the better. Kenneth & Kevin are joined by Riaz Moola from HyperionDev and the Computer Science Association of South Africa (CSASA) to talk about teaching programming online. Riaz is an accomplished young man, sporting two international masters degrees and the leadership skills to tackle the thorny issue of improving the education in the country. Almost by accident Riaz developed an online Python training course for students at the University of KwaZulu-Natal, which grew into HyperionDev, and also helped set up the CSASA to help educate our educators! HyperionDev is currently helping more than 8000 learners complete various of its community created and supported courses! We discus some of the challenges faced by learners, the (comparatively) huge drop-out rates in Computer Science courses, building a MOOC for the developing world and having backing from Google and the British Computer Association. This episode is shorter than usual, but still packed with an amazing story. Join us as we explore what it takes to give the next generation of developers a fighting chance!

Does infrastructure as code pave the way for repeatable, reliable, consistent and testable infrastructure? Join us as we found out. Kenneth, Kevin & Len are joined by Charlene Tshitoka from ThoughtWorks for a talk about infrastructure as code. Charlene has often gravitated towards the infrastructure of software projects, and after having worked on a distributed devops project she was propelled head first into thinking about infrastructure as code and how that can be leveraged to build more reliable infrastructure. "Infrastructure as code" is the combination of devops (automation, scaling, consistency) and software development best practices (versioning, modeling, testing, decoupling). Charlene shares from her broad experience of automating and controlling a diverse set of infrastructure with different teams and gives us a lot of good advice on how to think of infrastructure as code, and what the common pitfalls are the teams experience. This show is light on resources, and packed with fantastic insights and lessons!

Kevin and Len are joined by Simon Stewart to discuss the Swift programming language from Apple. Swift is a modern object oriented programming language intended to supersede Objective-C as the standard language in an Apple developer's toolbox. We talk about some of the quirks in Apple's developer ecosystem before unpacking some of the interesting language features Swift has to offer. We discuss topics such as tuples, pattern matching, generics, error handling and semicolons. There has also been talk about Swift 2.0's Linux compatibility and we discuss some of Simon's R&D into using Swift on the server side as well.

Kenneth, Kevin and Len are joined by Rebecca Franks to discuss the world of mobile development for Android, Google's developer platform and her recent Google Developer Expert accolade. We take a dive into all things Android, starting with the Play Store and the impact that's made on the app ecosystem before going into the more technical details of building and testing Android apps and the tooling behind it. We speak through some of the nuances of building against Android's APIs and look at alternatives to Java and the ability to interop with native code through Android's NDK.

We tackle the testy topic of automated testing in the life of software projects. Kenneth & Len are joined by Joshua Lewis from nReality (formerly of the JCSE) about the ins and outs of automated testing. We tear through artificial boundaries to unpack the value of testing, as well as potential pitfalls. There are many different testing tools and styles available, and choosing the right approach can be difficult. We even learned about some new terms, and possibly what we've been calling "testing" should be called "checking", who knew? We learned that Kent Beck, the father of TDD, did in fact "rediscover" TDD from earlier authors who used the same principles with punch cards! As is common with talks on testing we explore the many techniques we're aware of, sharing lessons learned and try to settle on some heuristics that you could use in your projects. Which methods are the best? You'll have to listen!

We tackle data visualization in its full technicolor glory! Kenneth, Kevin & Len are joined by Jeff Fletcher from IS Research & Innovation to talk about data visualization. Jeff has been working in the internet business for quite some time, from JINX to Telkom, Antfarm to IS, UUNet to 365 and finally back to R&I at Internet Solutions. We met Jeff a few years ago at Jozi.rb where he gave a D3 talk that blew everyone away. Since then Jeff has studied the art of successful data visualization and shares with us all the intricacies of generating effective graphics to communicate complex ideas. We got a history lesson on the origins of data visualization, starting with cartography and Florence Nightingale! We learn how visualization helped stop a cholera outbreak too!

In this weeks episode we share the inspirational story of two developers that have devoted themselves to teaching the disadvantaged youth of two prominent townships, Diepsloot and Olievenhoutbosch, to program. We chat to Theo Bohnen (https://twitter.com/tbohnenjnr) and Mandla Magagula (https://twitter.com/mandlamag) about their Sisonke Rising initiative. Sisonke Rising an impact and value driven community outreach programme that focuses on teaching young people life skills through the vehicle of software development. The aim of the initiative is ensure as many young people as possible are able to collaboratively code and build working software. Formerly called DrivenSpark, Sisonke came from the Zulu/Sotho word meaning "We are together", and together they focus on more than just code. They're a value-driven initiative. Values were chosen by the students themselves, and are reinforced every Saturday when they come together to learn. Their values include communication, feedback, courage, simplicity, care and fun. They have great support from their employer, Driven Alliance (http://drivenalliance.com/), and one of the founders (and former guest on the show) Kevin Trethewey (https://twitter.com/KevinTrethewey) who offers his own property and money to provide the students with books and snacks. They follow a spiral teaching model, where the more experienced students help the new entrants, reinforcing their skills. They rely on existing online teaching resources for their curriculum, using online typing courses, play online and offline games, and even getting them to submit their code to GitHub. Sisonke Rising is in desperate need of laptop donations for their students. If you have a working laptop that you no longer need, please contact Theo or Mandla to arrange for delivery. If you want to replicate Sisonke Rising in an underprivileged community near you, you can also get in touch with Theo & Mandla. Last, but not least, if you're willing to come help on a Saturday, get in touch with them and share your knowledge with the students.

In this episode Kenneth turns the table on Kevin and chats about a recent successful migration between clouds and architectures. Kevin and his team at Platform45 recently migrated a well established application (www.resourceguruapp.com) from AWS and EngineYard to Google Container Engine. This was a non-trivial migration from a managed platform and a collection of third-party services to a containerised deployment with minimal external dependencies. We talked about the challenges they faced (turned out to be not too many), the new stack they're building on and how Google Container Engine works. We dive deeply into the various components offered by Google's Kubernetes project, the open source technology that powers Google Container Engine, and how Kevin leverages them to take control of his environment. Technology aside, this does highlight the fact that it is possible to move between cloud providers. The team retooled their deployments to take advantage of Kubernetes' rolling deployments, they migrated their state from AWS to Google Cloud, communicated clearly with their customers and handled one unexpected event gracefully. In this age of containerised deployments this could potentially become the norm, whether you move between your own data centers, or between clouds.

Join us as we explore Clojure, the robust, practical and fast programming language. Kenneth, Kevin & Len talk to Robert Stuttaford (@RobStuttaford), co-founder and CTO of Cognician, about the Clojure programming language and his experience using it for the last few years. We discuss the language itself as well as some tools. We sing the praises of Rich Hickey, even if it just for his great talks, and stroll around the ecosystem including the obligatory stop at Datomic. Robert really did a great job of guiding us through the landscape and we're very excited about Clojure after this call. We'll definitely have Robert back in the future to cover Datomic and other parts of Clojure we didn't cover. Quick aside, the conversation was very organic and we skipped the formal introductions, and we had a few small technical snags with the recording, but the content is still great and we hope you enjoy listening as much as we did recording.

In this episode we explore the local world of open data and civic hacking. Kenneth, Kevin and Len are joined by Jason Norwood-Young (@j_norwood_young) from Code4SA (@Code4SA). Jason was a tech journalist in a previous life and "converted to the dark side" to become a developer. He's currently working with Code4SA on various open data and civic hacking initiatives and took us for a whirlwind tour of the space. We touch on a range of topics, from acquiring data from government and civil society, to the tools used to clean and interview the data, to publishing the data and building impacting projects that better the lives of people on the ground. We wrap up with some ways curious folks can get involved in the civic hacking movement, chatting local and global efforts to disseminate information and empower people. Follow Jason (https://twitter.com/j_norwood_young) and Code4SA (https://twitter.com/Code4SA) on Twitter.

In this episode we explore the world of indie game development. Kenneth and Kevin are joined by Sean Goncalves (@The_Son_of_Wolf) and Ben Myres (@_benjamming) from Nyamakop (@_Nyamakop), makers of independent games in Braamfontein, Johannesburg. We touch on the difference between "AAA" and "indie" games, tools of the trade, the experiences of releasing a game, and how accurate the Indie Game movie is. Ben & Sean share their experiences and observations and offers a ton of great insights and advice, and many ways to get involved in making games. We were pleasantly surprised to learn that there is a very active and successful community of game makers in South Africa. There are plenty of opportunities for beginners and experts alike to get involved with game development, and we hope to have helped clear some of the fog of war surrounding the topic.

In this episode we turn the spotlight on the Rust programming language. Kevin has been dabbling with it recently and shares his experience of exploring what Rust has to offer. "Rust is a systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety" - rust-lang.org Len and Kevin pick apart some of language features, the type system, memory safety, thread safety, platforms and its steeper learning curve. We make plenty of casual comparisons between different features of Rust and various other programming languages, including C, C++, Ruby, Java & Go. We also chunk up a bit higher and explore real life use cases like Servo (an HTML rendering engine), Diesel (an ORM that compiles the schema into your type system), Skylight (a Rails instrumentation service) and a few other hypotheticals we found. After that we check out the great documentation created by Steve Klabnik, exploring the pros and cons of executable comments. We discuss the basic tooling and package management system too. Our discussion then turns to their release process, the adoption of semver in the community, and whether it is a good bet for writing production systems. If you use Rust in production, or know somebody who does, please submit an issue on our ping repo for a future show!
