Every Job Its Own Adventure

In my four year carreer, I recently started my third job. This may make me come over like someone who very quicky changes jobs but I never changed job for the money or some other better deal I would get at the new location. I have always decided to leave based on the work I was doing at that time, altough I must admit that in no circumstance I have ever changed to a job that was offering me less then what I had. My quick passage at jobs may sound like switching could have been the wrong choice and that the previous job wasn’t that bad after all, this is what I will elaberate on during this blog post.

Distributed Teams

At my previous job they were starting up a new project on which many different people from different locations would contribute to. To give you an idea of how distributed the team would be, it would consist of 7 people in 4 different locations. Altough we have come a long way, and communicating with people all over the world has become possible without much effort there still are some problems that could arrise.

ObjectSavingFramework – Initial Version

As it goes with all software, initially you think you have it all figured out and it’s all clear, but as soon as you start writing it you realise there are a couple of things not as straight-forward as you would have liked. The implementation of the ObjectSavingFramework is no exception to this, even though it was designed to be a very simple application.

The first version only had to have 3 different concepts:

  • Objects: which contains other elements (potentially other objects).
  • Values: which just indicate a certain value.
  • References: pointers to objects.

The references are an important aspect to avoid infinite nesting, or object duplication. An object that contains another object will have to decide whether this object is private to him, or if it is shared. If it is a private object, the whole object needs to be written as a child element, if it is shared then the reference is required. It is however this reference concept that caused most of the problems.

ObjectSavingFramework – Concept

A common part of any application is to save data, altough there can be a big difference in the reason why you are saving data. Maybe it is just the output of the application which takes a certain input, processes it and writes some output again. But a lot of applications save data to have some kind of memory in case it is shut down, or in case of a failure. A lot of applications wouldn’t be thinkable without any way of storing data for later usage, even simple ones. I recently encountered this with the GroceriesInsight application, which currently doesn’t do much, but even then I already felt the pain of not being able to save the data.

Because of this saving data is a well known process that holds little secret. The first thing you would decide would be in what format you want to save your things, this can vary from a text format such as XML, JSON to a database. Once decided you will search for a library that makes it easy for you to write the data in a correct format. But then you are faced with how to get your data from the object to the library to save it, this problem will the be topic for this blog post.

Job Switch

After a long period of being bored at work, doing meaningless tasks and no real software development, I decided to switch jobs (again). Although I only worked there for little over two years, the situation has changed in such a way that staying is no longer an option. It’s a long story which started with a take-over causing a lot of confusion and uncertainty about the future. After this announcement a few people already left, but it wasn’t until that they re-organised the way of working, which completely destroyed the software team, and split it up into separate developers that it all went wrong for us. No effort was put anymore in advancing the product we had, no new projects were sold, basically all development came to a complete halt.

GroceriesInsight – Products & Transactions

The first thing to add is of course a way to add products and transactions as these form the core of the application. With the initial version I am aiming for a very basic form which just allows storing and retrieving data.

With the initial implementation of the Product and Transaction done, I will briefly explain how everything went, the thought process behind it and what I already know must be added in the future.

GroceriesInsight – Setup

Before starting any actual development I decided to dive into the features GitHub provides. Since it is just a personal project, I see little reason to start hosting my own Jira or other heavy applications that I would need to keep running somewhere. Instead I would opt for free cloud-based solutions. As a fact I know that GitHub has a lot of features, which is nice because then everything is located in a single location.

I have however never used any of these features, and thus I was out for an interesting journey on setting everything up. In the end the goal was to have a nicely organised repository with a clear flow, where merging branches and continous integration is standard.
