Why you, as a designer, should know the domain you are working in, not just base your choices on user insight.​​​​‌‍​‍​‍‌‍‌​‍‌‍‍‌‌‍‌‌‍‍‌‌‍‍​‍​‍​‍‍​‍​‍‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‍‍‌‌‍​‍​‍​‍​​‍​‍‌‍‍​‌​‍‌‍‌‌‌‍‌‍​‍​‍​‍‍​‍​‍‌‍‍​‌‌​‌‌​‌​​‌​​‍‍​‍​‍‌‍​‍‌‍‌‌‌‍‍‌‍‍​‍‌‌‍​‍‌‍​‌‍‌‍‌‌‍‌​‍‌‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‌‍‌‍‌‌‌​‍‌‍​‌‍‌‌‌‍​​‍‍‌‍​‌‌​​‌​​​‍‌‍‍‌‌‍‍‌‌​‌‍‌‌‌‍‍‌‌​​‍‌‍‌‌‌‍‌​‌‍‍‌‌‌​​‍‌‍‌‌‍‌‍‌​‌‍‌‌​‌‌​​‌​‍‌‍‌‌‌​‌‍‌‌‌‍‍‌‌​‌‍​‌‌‌​‌‍‍‌‌‍‌‍‍​‍‌‍‍‌‌‍‌​​‌​‌​​​​​‌‌​‌​​‌‌​‌​​​‍​​‍​‍‌​‌​‌‍‌‍​​‌‍‌‌​‍‌​‌​​​‌‌‍​‌​‌‌​‍‌​‍‌​‌‌​‍‌‌‍​‍​‍‌​‍​​​​‍​​​‍‌‍​‍​​​‌‍‌​‌‍‌​‌‍​​‍​‌‍​‌​​​​‍‌‌​‌‍‌‌​​‌‍‌‌​‌‌​​‌‍‌​‌‌​​‍‌​​‌‍​‌‌‌​‌‍‍​​‌‌‍‌​‌‍‌‌‌​‌‍​‌​‍‌‍‍‌‌​​‌‌​‌‍‍‌‌‍‌‍‍​‌‍​‍‌‍​‌‌​‌‍‌‌‌‌‌‌‌​‍‌‍​​‌‌‍‍​‌‌​‌‌​‌​​‌​​‍‌‌​​‌​​‌​‍‌‌​​‍‌​‌‍​‍‌‌​​‍‌​‌‍‌‍​‍‌‍‌‌‌‍‍‌‍‍​‍‌‌‍​‍‌‍​‌‍‌‍‌‌‍‌​‍‌‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‌‍‌‍‌‌‌​‍‌‍​‌‍‌‌‌‍​​‍‍‌‍​‌‌​​‌​​​‍‌‍‌‍‍‌‌‍‌​​‌​‌​​​​​‌‌​‌​​‌‌​‌​​​‍​​‍​‍‌​‌​‌‍‌‍​​‌‍‌‌​‍‌​‌​​​‌‌‍​‌​‌‌​‍‌​‍‌​‌‌​‍‌‌‍​‍​‍‌​‍​​​​‍​​​‍‌‍​‍​​​‌‍‌​‌‍‌​‌‍​​‍​‌‍​‌​​​​‍‌‍‌‌​‌‍‌‌​​‌‍‌‌​‌‌​​‌‍‌​‌‌​​‍‌‍‌​​‌‍​‌‌‌​‌‍‍​​‌‌‍‌​‌‍‌‌‌​‌‍​‌​‍‌‍‍‌‌​​‌‌​‌‍‍‌‌‍‌‍‍​‍​‍‌‌

Er det 1:1 mellom designer og design? Eller er design "motoren" mer enn det en designer utøver? Hvordan ser vi på design arbeidet opp mot evolusjon og hypotesetesting? Er design simulering?

We all know it; application security is a shared responsibility and everyone in the team should act according to the secure lifecycle development process. But our experience is that security is one of the first non-functional requirements that are dropped when deadlines approaches or when management is setting up a budget for the next period.​​​​‌‍​‍​‍‌‍‌​‍‌‍‍‌‌‍‌‌‍‍‌‌‍‍​‍​‍​‍‍​‍​‍‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‍‍‌‌‍​‍​‍​‍​​‍​‍‌‍‍​‌​‍‌‍‌‌‌‍‌‍​‍​‍​‍‍​‍​‍‌‍‍​‌‌​‌‌​‌​​‌​​‍‍​‍​‍‌‍​‍‌‍‌‌‌‍‍‌‍‍​‍‌‌‍​‍‌‍​‌‍‌‍‌‌‍‌​‍‌‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‌‍‌‍‌‌‌​‍‌‍​‌‍‌‌‌‍​​‍‍‌‍​‌‌​​‌​​​‍‌‍‍‌‌‍‍‌‌​‌‍‌‌‌‍‍‌‌​​‍‌‍‌‌‌‍‌​‌‍‍‌‌‌​​‍‌‍‌‌‍‌‍‌​‌‍‌‌​‌‌​​‌​‍‌‍‌‌‌​‌‍‌‌‌‍‍‌‌​‌‍​‌‌‌​‌‍‍‌‌‍‌‍‍​‍‌‍‍‌‌‍‌​​‌​‌‍‌‍​‌​​​‌‍‌‍‌​​​​​​‌​​‌​‍‌​‌​​​​​​‌​​​‍‌​‌​‌‍‌‌​‍​​‍‌​‍‌​‍‌‌‍​‍‌‍​‌‍​‌​‍‌​‌‍​​​​‍​‌‍‌‍​‌​​​​​‌‍‌‍​‌​‌​​​‌​​​​‍​‍‌‌​‌‍‌‌​​‌‍‌‌​‌‌​​‌‍‌​‌‌​​‍‌​​‌‍​‌‌‌​‌‍‍​​‌‌‍‌​‌‍‌‌‌​‌‍​‌​‍‌‍‍‌‌​​‌‌​‌‍‍‌‌‍‌‍‍​‌‍​‍‌‍​‌‌​‌‍‌‌‌‌‌‌‌​‍‌‍​​‌‌‍‍​‌‌​‌‌​‌​​‌​​‍‌‌​​‌​​‌​‍‌‌​​‍‌​‌‍​‍‌‌​​‍‌​‌‍‌‍​‍‌‍‌‌‌‍‍‌‍‍​‍‌‌‍​‍‌‍​‌‍‌‍‌‌‍‌​‍‌‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‌‍‌‍‌‌‌​‍‌‍​‌‍‌‌‌‍​​‍‍‌‍​‌‌​​‌​​​‍‌‍‌‍‍‌‌‍‌​​‌​‌‍‌‍​‌​​​‌‍‌‍‌​​​​​​‌​​‌​‍‌​‌​​​​​​‌​​​‍‌​‌​‌‍‌‌​‍​​‍‌​‍‌​‍‌‌‍​‍‌‍​‌‍​‌​‍‌​‌‍​​​​‍​‌‍‌‍​‌​​​​​‌‍‌‍​‌​‌​​​‌​​​​‍​‍‌‍‌‌​‌‍‌‌​​‌‍‌‌​‌‌​​‌‍‌​‌‌​​‍‌‍‌​​‌‍​‌‌‌​‌‍‍​​‌‌‍‌​‌‍‌‌‌​‌‍​‌​‍‌‍‍‌‌​​‌‌​‌‍‍‌‌‍‌‍‍​‍​‍‌‌

The most important part of any data science project is the data. It does not matter how fancy your algorithm is if your data has low quality or does not capture the relationships you are interested in. In the end it all comes down to the simple truth: “garbage in, garbage out”. Data cleaning refers to a variety of methods for improving data quality. It can be a time consuming and challenging process, but the reward for properly cleaning your data can be great.​​​​‌‍​‍​‍‌‍‌​‍‌‍‍‌‌‍‌‌‍‍‌‌‍‍​‍​‍​‍‍​‍​‍‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‍‍‌‌‍​‍​‍​‍​​‍​‍‌‍‍​‌​‍‌‍‌‌‌‍‌‍​‍​‍​‍‍​‍​‍‌‍‍​‌‌​‌‌​‌​​‌​​‍‍​‍​‍‌‍​‍‌‍‌‌‌‍‍‌‍‍​‍‌‌‍​‍‌‍​‌‍‌‍‌‌‍‌​‍‌‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‌‍‌‍‌‌‌​‍‌‍​‌‍‌‌‌‍​​‍‍‌‍​‌‌​​‌​​​‍‌‍‍‌‌‍‍‌‌​‌‍‌‌‌‍‍‌‌​​‍‌‍‌‌‌‍‌​‌‍‍‌‌‌​​‍‌‍‌‌‍‌‍‌​‌‍‌‌​‌‌​​‌​‍‌‍‌‌‌​‌‍‌‌‌‍‍‌‌​‌‍​‌‌‌​‌‍‍‌‌‍‌‍‍​‍‌‍‍‌‌‍‌​​‌‌‍​‍‌‍​​‌‌​‌​‌‍‌‌‌‍‌‍​‌​​​​‍‌​‍‌​‌‍​​​‌‍‌‍​‍‌​‌​‌‍‌‍​​​​‌​‍‌‌‍​‍​‌​​‌‌‌‍​​‍‌​​‍​​​‌‍​‍‌‍​‌​‌​​‌‍​‍​‌‍​‍​‌‌‌‍‌‌​‍​​​‌​‍‌‌​‌‍‌‌​​‌‍‌‌​‌‌​​‌‍‌​‌‌​​‍‌​​‌‍​‌‌‌​‌‍‍​​‌‌‍‌​‌‍‌‌‌​‌‍​‌​‍‌‍‍‌‌​​‌‌​‌‍‍‌‌‍‌‍‍​‌‍​‍‌‍​‌‌​‌‍‌‌‌‌‌‌‌​‍‌‍​​‌‌‍‍​‌‌​‌‌​‌​​‌​​‍‌‌​​‌​​‌​‍‌‌​​‍‌​‌‍​‍‌‌​​‍‌​‌‍‌‍​‍‌‍‌‌‌‍‍‌‍‍​‍‌‌‍​‍‌‍​‌‍‌‍‌‌‍‌​‍‌‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‌‍‌‍‌‌‌​‍‌‍​‌‍‌‌‌‍​​‍‍‌‍​‌‌​​‌​​​‍‌‍‌‍‍‌‌‍‌​​‌‌‍​‍‌‍​​‌‌​‌​‌‍‌‌‌‍‌‍​‌​​​​‍‌​‍‌​‌‍​​​‌‍‌‍​‍‌​‌​‌‍‌‍​​​​‌​‍‌‌‍​‍​‌​​‌‌‌‍​​‍‌​​‍​​​‌‍​‍‌‍​‌​‌​​‌‍​‍​‌‍​‍​‌‌‌‍‌‌​‍​​​‌​‍‌‍‌‌​‌‍‌‌​​‌‍‌‌​‌‌​​‌‍‌​‌‌​​‍‌‍‌​​‌‍​‌‌‌​‌‍‍​​‌‌‍‌​‌‍‌‌‌​‌‍​‌​‍‌‍‍‌‌​​‌‌​‌‍‍‌‌‍‌‍‍​‍​‍‌‌

This day is going to be all about blending colors, or rather how you can do blending in CSS with mix-blend-mode! Those of you that have limited experience playing around with colors may wonder what blending is. It’s quite simple, blending is when you mix two colors together in order to get a new color - and yes, it’s exactly like when you played around with color tubes in kindergarten!​​​​‌‍​‍​‍‌‍‌​‍‌‍‍‌‌‍‌‌‍‍‌‌‍‍​‍​‍​‍‍​‍​‍‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‍‍‌‌‍​‍​‍​‍​​‍​‍‌‍‍​‌​‍‌‍‌‌‌‍‌‍​‍​‍​‍‍​‍​‍‌‍‍​‌‌​‌‌​‌​​‌​​‍‍​‍​‍‌‍​‍‌‍‌‌‌‍‍‌‍‍​‍‌‌‍​‍‌‍​‌‍‌‍‌‌‍‌​‍‌‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‌‍‌‍‌‌‌​‍‌‍​‌‍‌‌‌‍​​‍‍‌‍​‌‌​​‌​​​‍‌‍‍‌‌‍‍‌‌​‌‍‌‌‌‍‍‌‌​​‍‌‍‌‌‌‍‌​‌‍‍‌‌‌​​‍‌‍‌‌‍‌‍‌​‌‍‌‌​‌‌​​‌​‍‌‍‌‌‌​‌‍‌‌‌‍‍‌‌​‌‍​‌‌‌​‌‍‍‌‌‍‌‍‍​‍‌‍‍‌‌‍‌​​‌‌‍‌​‌‍​​​‌​​‌‍‌‌​​‍‌‍‌​‌‍‌‍​‍‌​​‌‌‍‌‍‌‍‌‌‌‍​​‍‌​‌​‌‍‌​​‍​​‌‍​‍‌‌‍​‍​‌​‌​​‍‌​‍‌​‌‌‍‌‌​​‍‌‍‌‍​​‍‌‍‌​​‍​‌‍‌‌​‍​​‌​​​​‌​‍‌‌​‌‍‌‌​​‌‍‌‌​‌‌​​‌‍‌​‌‌​​‍‌​​‌‍​‌‌‌​‌‍‍​​‌‌‍‌​‌‍‌‌‌​‌‍​‌​‍‌‍‍‌‌​​‌‌​‌‍‍‌‌‍‌‍‍​‌‍​‍‌‍​‌‌​‌‍‌‌‌‌‌‌‌​‍‌‍​​‌‌‍‍​‌‌​‌‌​‌​​‌​​‍‌‌​​‌​​‌​‍‌‌​​‍‌​‌‍​‍‌‌​​‍‌​‌‍‌‍​‍‌‍‌‌‌‍‍‌‍‍​‍‌‌‍​‍‌‍​‌‍‌‍‌‌‍‌​‍‌‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‌‍‌‍‌‌‌​‍‌‍​‌‍‌‌‌‍​​‍‍‌‍​‌‌​​‌​​​‍‌‍‌‍‍‌‌‍‌​​‌‌‍‌​‌‍​​​‌​​‌‍‌‌​​‍‌‍‌​‌‍‌‍​‍‌​​‌‌‍‌‍‌‍‌‌‌‍​​‍‌​‌​‌‍‌​​‍​​‌‍​‍‌‌‍​‍​‌​‌​​‍‌​‍‌​‌‌‍‌‌​​‍‌‍‌‍​​‍‌‍‌​​‍​‌‍‌‌​‍​​‌​​​​‌​‍‌‍‌‌​‌‍‌‌​​‌‍‌‌​‌‌​​‌‍‌​‌‌​​‍‌‍‌​​‌‍​‌‌‌​‌‍‍​​‌‌‍‌​‌‍‌‌‌​‌‍​‌​‍‌‍‍‌‌​​‌‌​‌‍‍‌‌‍‌‍‍​‍​‍‌‌

Years ago, the JavaScript language was gifted with the Symbol primitive. Unlike many other language features in ES6, it was not simply a shorter syntax for doing something otherwise previously possible. It is not obvious what the point of these symbols are, and they are not commonly used. If you try to read up on them, you will find that many articles focus on details that are not important to the purpose of symbols.
