Why Do We Still Write CRUD Applications?

Probably every software developer - since the 1990s at least - has been there once, asking him- or herself: "Why do I have to write tedious, repetitive CRUD code time and time again?" Being good, virtuous programmers some of those developers did what software development in the end mostly is about: They tried to automate a cumbersome, repetitive process that like any repetitive process should be performed by machines rather than humans. Some have succeeded - to some degree at least - ...

Using Netflix Zuul As a Reverse Proxy / API Gateway

Zuul, which like the service discovery tool Eureka and the fault tolerance library Hystrix is part of Netflix' cloud orchestration stack, is a reverse proxy / API gateway. A reverse proxy conceptually works like this: A reverse proxy allows you to route requests to a single domain to multiple backing services behind that proxy. This can be conducive in situations where you want to break up your application into several loosely-coupled components that externally, that is facing the user, nonetheless act as if ...

Using Spring JdbcTemplate Instead of Object-Relational Mapping

Spring JDBC and Spring JdbcTemplate in particular has become my go-to tool for accessing relational databases for quite some time now and for good reason in my opinion: The common way for using data from an RDBMS in an object-oriented context used to be and for the most part still is object-relational mapping (ORM) frameworks like the Java Persistence API (JPA) or Rails' ActiveRecord. As the name suggests these frameworks attempt to map data (and concepts) from relational, set-oriented data structures, which ...

Flexbox Explained with Animations

Flexbox is a fairly new CSS3 layout standard that allows you to have layout elements automatically fit the available space according to layout rules defined in a website's stylesheet. While as of today still a W3C Candidate Recommendation Flexbox is already well-supported by all major browsers. In contrast to tried and true block- or grid-based layouts with Flexbox the onus of defining the exact placement of an element isn't on the designer but the browser. Flexbox therefore is much more, well, flexible ...

The Noun Project – Building the World’s Visual Language

Today there's certainly no shortage of icon sets and icon search engines (see the list below for a selection of those). These come in different flavours, mostly as icon fonts or SVG files, and can be easily integrated in a website or web application using standard HTML and CSS techniques. A particularly ambitious offering though is the Noun Project. The Noun Project provides a huge collection of curated icons (or rather huge amount of icon collections) created by a large community. Their ...
