136: Delving into Cryptocurrencies with Jay Smith

In this episode we are lucky to have cryptocurrency proponent and trader Jay Smith on the show. We start off by talking about how he got introduced to cryptocurrencies and trading, highlighting what trading actually is, and the two different schools of thought (fundamental vs. technical analysis). From here we move on to chat about how innovations such as Bitcoin are changing the way we view money/bank, the underlying technologies that make it possible (Blockchain), and the game-theory/incentives behind it for each participant to continue ‘playing the game’. Conversation then moves on to touch upon alternative cryptocurrencies (alt-coins) and the different use-cases/advancements they are making in the space. Finally, we highlight Bitcoins scaling dilemma, how all routes seem to effect decentralisation in some shape or form, and how he stores his private keys.


135: Let’s AWS Everything!

In this week’s episode Edd and Mick catch-up after another long hiatus (sorry about that). We start off by discussing principles mentioned in the Clean Coder book, gaining confidence in code by way of tests, and Elon Musk’s dream of putting a person on Mars. Leading on from this, Edd talks about his continued venture into the internals of Bitcoin, Hardware wallets, ASIC mining USB sticks and Merkle Trees. We then highlight MyBuilder’s recent switch from dedicated servers to the AWS stack, highlighting the pros n’ cons of both approaches and some gotcha’s encountered along the way. Finally, we mention some security audit and monitoring tools that have proven useful for keeping an eye on the (ever increasing) servers present in a typical setup.


134: The Agile Approach to Bitcoin

After a month ‘off the airwaves’, Mick and Edd are back to delve into several topics that have been keeping them interested. We start off by going down the Cryptocurrency rabbit-hole, highlighting the internal technologies that make up Bitcoin and its practical use-cases. Edd’s ramblings touch upon Satoshi, Cypherpunks, Merkle trees, Consensus algorithms, Hard forks, Segregated witness, Mining, Peta-hashes and much more… Once Edd (finally) lets Mick talk, we move on to chat about a book Mick is reading on Scrum, and question some different Agile practises. Finally, we ask the burning question ‘What is the Internet, Anyway?’.


133: RFC Showdown, Round 2 with Joe Watkins

In this weeks episode we catch up with Joe Watkins discussing all things PHP. We start off the discussion with how his role as release-manager is going for PHP 7.1, highlighting how Security bugs are defined and handled within internals. Following this we chat about several RFC’s that are under-discussion (Retry Keyword, UUID) and accepted (Libsodium, Object Typehint) for the next release. Finally, we mention a recent small extension Joe has been working on to provide user verified types within the language.


132: Caching using Varnish with Mattias Geniar

In this weeks episode we discuss the Varnish ‘HTTP accelerator’ with Mattias Geniar. We start off the show with the problem Varnish is trying to solve, how it decides to cache content and the power within its’ request/response life-cycle. We then move on to highlight testing strategies, tools to gain insight into your Varnish instance and cache invalidation options (Purging vs. Banning). Finally, we touch upon Edge Side Includes, Mattias’s own podcast and his new DNS Spy product.


131: Servers, Upgrades and a little Cryptocurrency

In this weeks episode we start off by discussing Edd’s recent Server build, touching upon the hardware specifications, OS/ZFS-pool choices and monitoring configuration. We then move on to highlight the value in splitting up computational intensive tasks into queued jobs, defensive programming in JavaScript and handling querying ever increasing data-sets. Finally, we talk about keeping on-top of Software/Dependency upgrades, moving over to platforms such as AWS and Ethereum.


130: Cyber Security with Colin Hardy

On this weeks show we are joined by Colin Hardy to discuss all things Cyber Security. We start off by explaining what got him interested in this branch of computing, highlight what Cyber Security is, and define some of the common terminology. From here, we move on to discuss how he analyses Malware samples (using Automated, Behavioural and Static means) and the diagnostic tooling present. Finally, we mention some high-profile attacks (Stuxnet, WannaCry), motives behind creating such Malware and how he stays current in this field.


129: The Applied Mathematics of Programming with Liam McLennan

In this weeks episode we are lucky to have Liam McLennan on the show. We start off discussion with his Math background, how he got into programming and how it can be seen as Applied Mathematics. From here we move on to highlight his experiences whilst consulting, what it entailed, and the importance of ‘tact’. This leads us on to look into what drew him to Functional programming, F# and creating Pluralsight courses. Finally, we delve into the different areas of the Nokia Ringtone Composer Emulator from his F# Fundamentals course.


128: Catching up with Mr. Hart

In this weeks episode we are joined by fellow co-host Fraser Hart. We start off by discussing what he has been upto since his last podcast appearance - ranging from completing an Ironman, to promotions at work. From here we highlight how he balances development with his new project managerial role, how his company has started to adopt React/Redux and moving over to Webpack 2. Finally, we delve into the different server stacks we are using, and how the KISS design-principle plays a key-role.


127: More Server Talk with Brian Moses

In this weeks episode we are again lucky to be joined by Brian Moses, to continue our discussion on building your own home server. We start off by highlighting what ECC memory is and its’ value in a home server setup. Following this, we chat about looking into the second-hand market for hardware components - as an option to find a good deal. This leads us on to discuss overclocking hardware, threads vs. cores within a CPU and what Hyper-threading actually is. Finally, we mention some different NAS Operating System solutions and Brain’s foray into the world of Quadcopters.
