Google Summer of Code wrapup: OpenMRS

Google Open Source Blog - Fri, 10/24/2014 - 18:00
As a long-time Google Summer of Code participant, OpenMRS had twelve Google Summer of Code students in 2014. One of those students, Stephen Po-Chedley, writes more about his experience below as well as other students’ projects.

OpenMRS logo
Waking up to an uneventful landing in September 2013, I found our plane surrounded by dry grass fields. I couldn’t even tell that we were on a runway. I had slept through the approach over small clay houses and family gardens. This small, dusty country of Malawi is where I would spend the next year.

Prior to Autumn 2013, I had been a PhD student studying climate change in Seattle. As part of my research, I was constantly working through random technical and computational challenges. It seemed like every week I was hacking together some code in some unfamiliar language. While the work was challenging and interesting, I wanted to take some time away from my studies to apply some of these technological skills to issues even more acute than climate change.

Upon deplaning, I stepped away from supercomputers meant for climate research and found myself in Malawi working with barely functional laptops. As a volunteer with a health NGO in Malawi, I was slotted to help support the OpenMRS based electronic medical records system that was crucial for monitoring and evaluating the remote district’s health progress. OpenMRS is an open source medical records system used on every continent. The system was created to help provide management tools to meet global health challenges, especially in resource poor countries.

I quickly understood why OpenMRS was such an important tool. The system could generate reports to help us track down patients that had missed appointments, we could flag people who needed a change in medication or a new lab test, doctors could get an overview of their clinical practices, and clinical programs could get a snapshot of their patient cohorts.

Of course, any information that we derive is only as good as the data it comes from. With an entire district of health data being fed into the system, it is easy to miss some parts of records or mis-enter information. Any errors have the potential to affect patient care or high-level decisions made about programs. We need not only good data, but to also understand the quality of the data we have. And this is where Google Summer of Code (GSoC) became so important.

Over the last few months, I was able to work with mentors to design and begin to build a module within OpenMRS to help assess data quality. Beginning work on the project was terrifying for me because my programming experience was mostly hacking together code for scientific analysis. Most of my programming education has been through exhaustive Google searches and discussions with fellow geeks, but this was nearly impossible in Malawi working off of an unreliable satellite internet connection with pretty limited bandwidth.

But I could see that the project was important. My mentors were awesome and the OpenMRS community was incredibly supportive, offering invaluable advice to those that are new to the community. Throughout the summer, I learned a ton of new technologies and — together with my mentors — made a lot of progress on our project.

Being involved with OpenMRS and Google Summer of Code 2014 was incredibly exciting and I feel fortunate that there are opportunities to continue to stay involved with the community. One important lesson was that open source projects have all kinds of ways to help. The OpenMRS tagline for GSoC is “Write code. Save Lives.” From my experience as an implementer and developer of OpenMRS, that motto rings completely true. It has been inspiring to see code pieced together by a diverse community of contributors from all over the planet to create a system that is literally saving lives.
You need look no further than the projects worked on during GSoC 2014 to get an idea of all the important work going on at OpenMRS:

On behalf of all the students involved with OpenMRS and the Google Summer of Code 2014, thank you to OpenMRS and to Google for supporting our work and to our mentors that helped make the summer so successful. It was an incredible opportunity to learn so much from world-class mentors, be involved in important work that makes a huge difference, and to get exposure to the rich communities that support open source projects.

walbouncer: partial transaction log replication

PostgreSQL News - Wed, 10/22/2014 - 01:00

We are proud to announce walbouncer 0.9 - a tool to filter transaction log. At this point we are moving rapidly closer to a production-ready tool.

The key advantage of walbouncer is that it is no longer necessary to replicate entire database instances. You can filter out entire databases and tablespaces and selectively choose what to replicate.

walbouncer can act as a WAL proxy distributing data flexible to various servers containing different subsets of data.

walbouncer is open source and can be downloaded freely from our website. Currently PostgreSQL 9.4 is supported.

Mercurial Makers Meet in Munich

Google Open Source Blog - Tue, 10/21/2014 - 18:45
Back in August, the Google Open Source Programs Office sponsored a meetup for contributors to Mercurial, a distributed version control system. Learn more about their two day hackfest below.

On August 29th-31st, the Mercurial project held one of its twice-a-year sprints in the Google Munich office. Mercurial is a distributed version control system, used by Python, OpenJDK, and Firefox among others. We had 24 developers in attendance, some from companies with large Mercurial deployments and some individual contributors who volunteer in their spare time.

One of the problems Mercurial wants to tackle soon is scaling from supporting hundreds of thousands of files to supporting millions of files in a single repository. The community has identified two approaches to scaling: shallow clones and narrow clones. Shallow clones will allow clients to pull down only part of a repository’s history, and narrow clones will make it possible to pull history for only some files.

At the sprint, we talked through some of the initial narrow/shallow clone implementation hurdles, like how to securely and efficiently store large manifests, and made good progress on a plan. We spent time working on changeset evolution, which makes it easier to manage the process of collaborating on a patch before it’s done. A group also discussed how to make bookmarks work better for users of changeset evolution in large systems, including developing a good plan around remote bookmark management.
If you are interested in finding out more about Mercurial (or perhaps you’d like to contribute to make it scale even better!) you can find our mailing list information here.
