Why are legacy apps be forgotten?

Legacy apps are the bane of developers. Many have to work on one, nobody loves them. But why do they grow to such a pain?


A huge problem of legacy apps

Last Update: 20.11.2018. By Jens in Newsletter

I know legacy apps cause many issues. Nobody really wants to work on one. The funny thing is, most of them are already the legacy problems roughly a half year after the first release. At least in my experience. Anyways, one of the problems can become a nightmare after a few years.


Write your assumptions down

Keep a list of your assumption during development. After all, we’ll probably never ever answer all of our assumptions before we develop anything.


Assumptions

Assumptions are everywhere.

If you think about going solo - becoming self-employed, read this article first and this comment too. It’s so true.


Use-case driven naming

Besides being consistent with naming, I think readability and easy understanding are also important. I sum that up as use-case-driven.


Being consistent in naming

Last Update: 08.11.2018. By Jens in Newsletter

Naming things like classes, methods or packages can be hard. Especially if you are not working alone. However, I don’t think there is a universal rule for naming things. It depends on the context. WHat comes close to a universal rule, is being consistent with naming. If you are working in a team and everybody on it names their classes and packages differently, it becomes a mess.


Java books for you

Last Update: 05.11.2018. By Jens in Newsletter

There’s a Java book bundle on humble bundle. It looks like a good mix of language stuff, cloud, Spring, reactive dev und machine learning with Java. Maybe that’s something for you, maybe not. Check it out and decide for yourself.


So glad I wrote docs....

I developed a small utility for sending bulk emails a year or so ago. Reads a CSV file, parses a text template and send the emails. Simple, tiny. Yeah, right.


I wrote a new book

Last Update: 01.11.2018. By Jens in Newsletter

but it is not about programming at all. Actually, I wrote it at the beginning of this year. However, in German, so I didn’t bother with writing about it here. A few months ago, I finally hired someone to translate it into English as I didn’t want to do it myself. I love writing books but not translating them :-)
