Software development is often described as “craftsmanship”. What is craftsmanship? And does that mean software development and programming have something in common with, say, a more traditional craft like handicrafts (sewing, knitting, weaving, etc)?
In this presentation, I will talk about the meta level similarities between handicrafts and programming, and demonstrate that any crafter/maker has the essentials meta level skills of a programmer.

React Hooks have been out for a while already and they have quickly become the new recommended way of handling component local state and side effects in React function components. Getting started with React hooks is quite straightforward, but the more you use them, the more you need to change the way you think about your components, especially when it comes to the useEffect hook. There are certain rules that you have to follow and certain pitfalls to avoid.
This presentation assumes you know the basics of React hooks and we will dive a bit deeper into how they can be used and how they should be used. In this presentation, I will explain the rules of hooks and how we messed up with those and I ended up wasting almost a month of my work time fixing the mess.

Still remember mid March? Most people were still working at the office, and the national pastime was hoarding toilet paper and hand sanitizer? Me neither, seems a lifetime ago.
In the beginning of the lockdown, nobody had any idea how quickly the novel coronavirus was spreading in Finland. Many - including the Health Security Director of THL - were calling for an app to crowdsource symptom data from the general population, in the hopes that it could be used to track the spread of the epidemic. Futurice, in close collaboration with Helsingin Sanomat and medical experts, was one of those who answered the call. In this talk Jarno will go through the technical implementation of the resulting oiretutka.fi service.

Maybe you are familiar with using Content Delivery Neworks, or CDNs for short? Maybe you have even used them yourself? Or maybe this is all news to you?
Let’s have a talk where we look into CDNs under the hood. What are they, who are they, why should you use one (or maybe should not), and how do they work? The CDN landscape is also changing, so we’ll dive into that a bit.
And we’ll go through why you shouldn’t build one yourself.

Wikidata is a community project with the goal to store all of the world’s knowledge in a machine readable format. This data can be viewed, edited and -most excitingly - queried by everyone. In this talk I will show how the Wikidata Query Interface allows us to ask questions about the world around us and can help us explore these with automatic interactive visualisations.
To do so, I will introduce the Wikidata project and explain how data is modelled in it. With this knowledge we will go on to learn about the SPARQL query language which allows us to write queries to Wikidata. We can then use the Wikidata Query Builder which is an online interface that turns queries into timelines, tables and other interactively explorable visualisations.
What kinds of queries can we expect? The world’s biggest cities with a female mayor. A map of German election districts coloured by winning party (or gender, or age, …). An interactive timeline of politicians who became federal ministers. Handball player nick names… (Almost) everything is possible with Wikidata!

Nowadays many projects do not use a traditional backend any more, but have moved their logic to FaaS (Function as a Service) like AWS Lambda. The core idea is that you don’t have to manage a server, but instead you just upload code and it will be executed on some event. Normally AWS only supports Nodejs, Python and a few more languages for this service. But with custom runtimes, we can deploy any language!
In this Tech Weekly, I will show how you can write a stateless service (in our case a telegram bot) in Haskell and deploy it to AWS Lambda with Terraform.

Have you ever ended up in a situation where you need to do a small change to an old TS/JS app that no-one has touched in months? Quite often, in these situations, the app does not work anymore, because of a change in a dependency or a dependency of a dependency. This is why http://npmplease.com/ exists. The JS ecosystem is inherently broken. There are cases where malicious packages have made thousands or millions of projects stop working.
In this presentation, Olavi will talk about how to avoid ending up in a huge mess with your node_modules, and how to handle dependencies in a future-proof way without loosing your time and energy waiting for “npmplease”.

Times of crisis are a test for how (or not) we have integrated accessibility into our processes. When the urge to help and to do things well apply tension, the shortcuts we rely on might mislead us.
In this talk, we will reframe the conventional “edge case” as a “stress case”. We will cover how accessibility benefits even more people in a crisis, and how our own processes can or should adapt under stress.
The last thing I want to do with this, is to put yet more pressure on you; we already have enough of that. Instead, I want us to look at the systems that are bigger than us, and which will only change with our collective effort.

Traditionally the web has consisted of fully Server Side Rendered (SSR) web pages. As new technologies popped up, more and more dynamic features got introduced. Then, came along React and the golden time of JavaScript based Single Page Applications (SPA). But now, we have gone full circle and “everyone” is talking about SSR again. Why?
