Deep dive into advanced TypeScript

Microsoft is arguably taking over the open source world. Esko, Paavo, Juuso and Sam debate the role the company plays in today’s open source community – TypeScript, GitHub, VS Code, npmjs.com and all – and discuss the advanced features of TypeScript.

Guests

Paavo Huhtala joined Reaktor at the age of 19. A self-taught hobbyist programmer since middle school, he likes pretty much everything – from writing compilers in Rust to adding that missing 0.5 pixels of left padding to the signups form’s submit button.

Juuso Mikkonen has been programming professionally since 2015 but still learns – mostly through mistakes – something new every day. His day-to-day tasks usually involve programming in TypeScript, building web services, remote teamwork and managing time zone differences.

Sam Grönblom is from Finland but relocated to Tokyo a decade ago. He’s partial to pragmatic, statically typed functional languages, and he wishes he could only program in F#.

Host

Esko Lahti is a programmer who loves to have his weekly mind blowing experience caused by a yet another neat TypeScript typing system trick.

Clojure and Its Superpower, The REPL

ft. Matti Lankinen, Toni Vanhala with Esko Lahti

Cheers to the 14th trip around the sun of the language that’s made up of data! In this episode, Esko, Matti and Toni discuss Clojure, REPL, and how you can use them in your next project.

Guests

Matti Lankinen’s programming career started from the little boy’s dream of making his own games. C++ was too hard at the time, so he started making his own programming language. It was never finished. (Hands up, who can relate?)

Toni Vanhala learned the alphabet by typing on the keyboard and copying BASIC programs his mother read aloud. A couple decades later, Toni got his Ph.D. after programming a custom gaze tracker, virtual humans that react to facial expressions, and a chair that senses emotions.

Host

Esko Lahti is an engineer who now works in the company that got him into Clojure. Now, his party trick at meetups is to rapid fire through an extensive list of parentheses jokes.

Category Theory for the Non-PhD – and What to Use It For

ft. Antti Holvikari with Esko Lahti

Category theory may strike you as intimidating, but trust us, you can (and after this episode, are probably itching to) talk applicative functors and parser combinators over afterwork drinks. Listen in to learn why Esko and Antti – both of whom started programming with dynamically typed languages – are so into category theory right now that they see applications of it everywhere.

Guest

Antti Holvikari is endlessly fascinated by pure functional programming languages such as Haskell and PureScript. Software quality and personal productivity are two things he’s constantly improving.

Host

Esko Lahti is an engineer who always wanted to learn about category theory in practice – but never knew where to start. Then he met Antti Holvikari.

Finding the Corner of the Internet You Love with Amsterdam Hackers

ft. David Vázquez, Tijn Kersjes with Esko Lahti

Two years ago, David and Tijn formed Amsterdam Hackers: a group of developers willing to conquer and learn from tech problems they had previously found impossible. In this episode, Esko talks to the two Amsterdam-based engineers about the group’s philosophy, as well as their two largest projects; the gbforth and Delisp.

Guests

David Vázquez grew up sitting next to his father, watching him code in Clipper. Having coded in Microsoft Access and Visual Basic, he got into Linux and C around 2002. David then learned Emacs and Lisp that introduced him to programming language design and implementations. The rest is history.

Tijn Kersjes discovered programming as a kid when he realised you can create games rather than just play them. Eventually, he decided to combine his two passions (drinking coffee and writing code) into a software development career.

Host

Esko Lahti is an engineer who enjoys team work over solo work of any kind.

The Promise of Tasks: Concurrency in a Single Threaded World

ft. Andy Davies, Otto Paaso with Esko Lahti

Multiple threads or only one thread, and why should it matter? Blocking or non-blocking IO, and what benefits do each of them offer? What’s the problem of using callbacks? Hold on to your hats, folks – in this episode, Esko, Andy and Otto plow through some of the most fundamental questions regarding runtime environments.

Guests

Andy Davies is a software developer who likes making other developers’ lives easier, usually by providing libraries, tooling, infrastructure, build systems, and ways of working. He likes keeping things simple. He doesn’t like Kubernetes.

Otto Paaso also likes simple things (and static types). For the past 12 years he has been working on embedded, desktop and web products, as well as the necessary backend and infrastructure technologies to make things rock.

Host

Esko Lahti is an engineer who wants to know how things work under the hood, no matter how many threads are involved. He has no horse in the Node.js vs JVM race.

Time to Ditch the Boilerplate: Safe, Fast and Easy Data Manipulation with Statically Typed Optics

ft. Petri Lehtinen with Esko Lahti

Still writing bespoke functions and boilerplate to immutably manipulate a complex data structure? Statically typed optics will both do the heavy lifting for you, AND give your TypeScript hustle an unforeseen boost.

Guest:

Petri Lehtinen started programming with Basic in the mid-90s. Open source projects and functional programming in typed programming languages are close to his heart.

Host:

Esko Lahti is an engineer who saw the light after first encountering the partial.lenses optics library in 2017.

GraphQL is the God Mode of Web Development

ft. Ian Fosbery, Dirk Geurs with Esko Lahti

GraphQL has arguably changed the entire paradigm of writing full-stack web applications. In today’s episode, Esko, Ian and Dirk discuss GraphQL, Apollo, and Relay, and why they can, in good conscience, be called a web developer’s cheat codes.

Guests:

Ian Fosbery is a big believer in good communication—both face-to-face, and through code. For the past 15 years, he has been building products, writing code, and getting excited about everything from good software design to devops and scale.

Dirk Geurs is a technologist interested in creating high-performing software teams. Over the last year, he worked on various cross-platform mobile applications.

Host:

Esko Lahti is an engineer who is lazy and loves to take the easy way out. (Editor’s note: No one has ever witnessed Esko take an easy way out of anything.)

Will Harmaja be the React Killer we've been waiting for? ft. Juha Paananen, Jussi Saurio

ft. Juha Paananen, Jussi Saurio with Esko Lahti

React, it turns out, is not what lies at the end of the web development rainbow. In this episode, Esko, Juha and Jussi talk about achieving super fast user interfaces by combining functional programming techniques and embedding observables directly into the DOM with Harmaja.

Guests:

Juha Paananen started coding with Commodore computers in the 80s and is a proud holder of both IBM WebSphere and XML certificates. Juha is the author of Harmaja, but perhaps best known in the open source community as the creator of the Bacon.js library. He loves functional programming, electronics and generally writing stuff from scratch.

Jussi Saurio quit his job as an English teacher in late 2016 and started teaching himself software development. After three months of intense self-study, he scored his first tech job, and the rest is (fairly recent) history.

Host:

Esko Lahti is an engineer who still remembers the struggle of using Apache Wicket and JSP to create web applications.
