Dozens of new plans on Blueprints wiki

If you didn’t follow our Blueprints wiki or twitter you might have not notices that it’s boiling with new ideas !

In this post will give you a short summary of the most important analysis and design efforts that are taking place there. We are always happy to hear your feedback so please feel free to comment and even edit those blueprints.

Production scheduling on the level of operations, workstations and workers

This is probably the most important new module we have scheduled in our roadmap. For now you can plan production orders in the Gantt chart and calculate how long will they take if they ware to be executed independently. If we introduce the concept of tasks and resource capacity then we will be able to do very precise calculations how long a new order should take in the context of the current orders. This will also introduce detail plans which indicate what and when should a workstation/worker produce

3 interns hired in our open source project

As you may have noticed we have been running a long term student internship program to teach upcoming engineers how to create modules for qcadoo MES. We also wanted to show them the qcadoo Framework which they can use for their next killer apps. During this time many interesting young people worked with our battle-hardened old-school team :) Three of them (that seemed most talented to us) just got hired lately in Qcadoo Limited.

The cloud as a system architecture

First of all what does ‘the cloud’ really mean ?

Is it really a technical term or just a marketing slogan ?

According to the father of the free software movement Richard Stallman:

It’s stupidity. It’s worse than stupidity: it’s a marketing hype campaign.

You can also find similar opinions on the other side of the barricade. For example CEO of the Oracle Corporation Larry Ellison starts by saying that:

It’s nonsense and water vapor

and follows it by 4 minutes of jokes about clueless cloud advocates :)

Installation video tutorials

Sometime ago we got burned a little on forums because the install was not straightforward to many users. Unfortunately this is how it always looks in server-side applications and you can see many other open source business systems (ERP or CRM for eg.) that have the same problem.

To ease the installation process a little one of our community members Iwo Kosowski-Banasiak has prepared a set of video tutorials:

Each shows step by step how to install qcadoo MES. Choose them depenting on your preferred language and operating system.

We hope this will help.
