PLUG Advanced Topics: Allison Randal

By in Linux

Allison Randal gave a presentation entitled, “Ubuntu Release Engineering” last night in Portland. During her presentation Allison gave some insights into how she coordinates the efforts of her developers and how the release cycle helps make sure the project members’ efforts are coordinated.

Allison displayed two graphs in particular that piqued my interest. The first was a sloping bar graph depicting the completed tasks in green and the incomplete tasks in red. The green area at the top increased in area while the red area decreased as time progressed. The graph was visual way of representing project progress over time. It also clearly showed how much still needed to be done. Instantly. Very nice.
The second graph showed the spacial relationship between the various projects in Ubuntu’s world. The graph was created automatically through scripts that perform natural language parsing the work orders. From that information an updated spatial view of the relationships between the projects is created.
You can tell that Allison cares about her people and the projects she oversees. She’s really conscious to make sure she has her finger on the pulse of the OSS community.

Logical Volume Management

By in Information Technology, Linux

Logical volumes are logical constructs relating to mass storage devices. Logical Volume Management systems make several physical disks seem like one or more large storage areas.

I wrote a presentation handout on LVM as seen in the linked document entitled, Logical Volume Management.

Server Side Spam Filtering

By in Information Technology, Linux, Programming

I ran across a document that I wrote in 2003 outlining the spam filtering process in Postfix for a client I had at that time. I had fun working with this client, for reasons not the least of which as they were happy to let me release my documents under the GPL v2 license.

I have the PDF document linked here.
