Web Dev Bros

When you implement a new feature somewhere, when you change just some bits of your code, when you fix a bug, or you just change a common text in an app… What do you do afterwards? Do you really check the result or do you trust yourself that it works fine 100%. It is an interesting thing to talk about… Continue reading ‘Testing code changes, bugfixes, new features, …’ »

I was having trouble to differentiate between both nor could I 100% explain to someone what’s the real difference between a Service and a Component. Today I’ve found a really nice definition by Martin Fowler which I would like to share with you:

Component

I use component to mean a glob of software that’s intended to be used, without change, by application that is out of the control of the writers of the component. By ‘without change’ I mean that the using application doesn’t change the source code of the components, although they may alter the component’s behavior by extending it in ways allowed by the component writers. – Martin Fowler, Inversion of Control Containers and the Dependency Injection pattern

Service

A service is similar to a component in that it’s used by foreign applications. The main difference is that I expect a component to be used locally (think jar file, assembly, dll, or a source import). A service will be used remotely through some remote interface, either synchronous or asynchronous (eg web service, messaging system, RPC, or socket.) – Martin Fowler, Inversion of Control Containers and the Dependency Injection pattern

During my previous holidays (i have to admit 1.5 months surfing in portugal) I had some literature with me which also included the book Programming .net components released with O’Reilly. It talks about the aspects of components in general and provides good examples how to achieve those in .net. Although these pages are a very good read (rather for experienced devs) for ppl interested in component development, I found it more interesting because of its general C# content. There are concepts & approaches, small tips & tricks and intersting things about C# which can be used not only in component based architectures and are therefore good to know anyway.

As I always make notes while reading “geek” books I thought: “so why not summarize them all up in a nice list and blog’em”. Here we go… Continue reading ‘C# tips, tricks and things you should know’ »
