At this point, you might be asking yourself, “what the heck is DEMO?” As stated on their website: “DEMO is a launchpad for emerging technologies.” DEMO events have been going on for about 20 years. The events provide an opportunity for companies launching emerging technologies to interact with their peers, potential investors, and others interested in their products. Read more of this post

Jitterbit/Thomas Nelson ETL Case Study

In today’s complex technology environment, having the right ETL (Extract Transform Load) tool is a top priority for many enterprises. In the past, my team has built its own ETL tools. While they have worked well for us, maintenance and support in a rapidly changing world has become somewhat of a nightmare. Read more of this post

10 Indispensable Insights On Cloud Computing — InformationWeek

It’s based on the book: Management Strategies for the Cloud Revolution, by Charles Babcock…something else for me to read. Read more of this post

More Mingle Chart Modifications

As much as I like Mingle…except for its speed…there are a couple of things that have bothered me for a while: the straight lines to infinity when a chart goes beyond current data points and hard coding dates as labels in charts. It turns out that there are a couple of easy resolutions to both problems.

If your burn down chart has parallel horizontal lines running off the chart to the right, simply remove the “x-labels-end” tag and save the chart. Your new chart will end at the most recent data point.

Onto the second issue. Instead of hard coding dates into your charts, causing them to modified every time you need to change a date, use a project variable. Since my charts are primarily based on release, I created a date project variable  called “Release Start” that I use on the x axis: x-labels-start: (Release Start). Now, I only have to go to one place within my project to maintain the release start date.

Hope this helps with your Mingle adventures. For more Mingle chart modifications see this post and this one.

Simple Mingle Overview Charts: Project Backlog

One of the items I  track in an Agile project is what my team refers to as “Project Backlog.” The Project Backlog contains stories that have yet to be accepted and assigned to a sprint or release. For purposes of estimating project end dates, I keep a running tab on the total stories in the Project Backlog at any given time.

In Mingle, I’ve developed the following tracking chart:

Here’s the code to create this chart:

{{
data-series-chart
cumulative: true
x-labels-start: 04/01/09
x-labels-end: 05/30/09
x-labels-step: 7
x-title: Date
y-title: Stories
chart-width: 400
plot-width:  200
three-d: false
chart-type: line
series:
– color: orange
data: SELECT  ‘Added On’, COUNT(*) Where type = Story AND  ‘Planning – Release’ IS NULL and ‘Planning – Sprint’ IS NULL and ‘Added On’ <= TODAY and Status != ‘On Hold’ and Status != ‘Deleted’
type: line
line-width: 2
trend: false
}}
