In this episode, Ronald talks about why you should track the time you spend on a project/tasks as well as some of the ways/tools that you could use to track them. Ronald also talks about the plans for the micro robots. Ronald also briefly explains how RTOS work and give an example where you could use it.
Show Notes

For a contractor/freelancer, keep track of your time on a project/task is important. it could mean the deference between making or loosing money
Over estimating the time it takes to complete a project/task could be just a bad as underestimating it
Project tracking is a pain to do and can slow you down in some cases
Its hard to estimate a task because of the nature of the job we do. Its not like we have an IKEA instructions for the product that we design
PERT charts– Program evaluation and review technique
Gantt chart
Ronald went to Embedded Systems Conference 2009. Here’s where I first meet Jack Ganssle but I doubthe remembers Ronald
Should Manager have the same discipline as the people they are managing?
The assumption that your manager makes isn’t necessary same assumption that you are
