Dan Abramov on The Elements of UI Engineering

Somewhat recently, Dan Abramov wrote this interesting piece on his approach to learning about UI engineering. The article's key takeaway is this: "My biggest learning breakthroughs weren’t about a particular technology. [ ... ] It’s this combination of understanding the problems, experimenting with the solutions, and applying different strategies that led to the most rewarding learning experiences in my life." In keeping with this wholistic, problem- rather than technology-oriented approach Dan starts with outlining the problems and challenges he has encountered repeatedly when developing ...

Cloud Design Pattern Library by Microsoft

Microsoft maintains an extensive library of cloud design patterns. Whether you create applications that run on AWS, Microsoft Azure or Google Cloud Platform, use platforms such as Heroku or you develop enterprise applications which run on on-premise cloud networks within a corporate intranet, cloud computing becomes ever more crucial to providing business value through software. Hence, it's not only expedient to know about the classic relatively low-level GoF design patterns or Martin Fowler's Patterns of Enterprise Application Architecture but about design patterns for ...

References to Design Pattern Libraries

When designing and developing software it's always useful to have a reference to common software design patterns handy. Apart from cloud design pattern libraries there are collections of more low-level or more general design patterns, too. These include the classic GoF design patterns and Martin Fowler's Patterns of Enterprise Application Architecture.

State of JavaScript Survey: 2018 Edition – Criticism from an Angular Perspective

Recently, the results of the 2018 edition of the State of JavaScript survey have been published. As usual, the report comes with handy categories such as front-end, data layer, testing or mobile. While I very much support the idea of creating a yearly survey of the JavaScript landscape and this survey in particular, which I have been supporting since its inception, there's a major issue with this year's edition: In contrast to its previous editions the survey results lump together (or at least the ...

Dinero.js: Working With Monetary Values in JavaScript

Working with monetary values can become a problem in any programming language and JavaScript certainly is no different in that respect. The naïve assumption that monetary values can be expressed as floating point numbers almost inevitably leads to rounding errors caused by precision and the fact that in most cases monetary values are represented as decimal numbers with just two (instead of an undefined number of) decimal places. Apart from that, money is not just a number but usually comprises a currency ...
