Open access to scientific research

May 24, 2012 1 comment

open access

Students, teachers, researchers, entrepreneurs, patients, caregivers, and other U.S. taxpayers deserve open access to scientific journal articles arising from U.S. taxpayer-funded research.

This is my belief, and I’m hopeful that enough of us share it and are willing to advocate for open access policies for all federal agencies that fund scientific research.

I just signed a petition to require free access over the Internet to scientific journal articles arising from taxpayer-funded research, and I invite readers of this post to show support.

It takes a minute to sign it! If implemented, open access policies for federally funded research will touch everybody’s education, formal and informal, for life-time.

POSSE Worcester: Day 4 – And more development

June 13, 2010 Comments off

Fedora on a stick with persistent overlay and other persistent-wise features (or live USB) has been a challenge. That’s something future POSSE will need to have solved. A pre-POSSE set of activities should involve participants in getting ready. Creating a live usb could be such a preliminary activity.

We had a very informative discussion on infrastructure and students’ involvement with an open source infrastructure in support of teaching and learning open source. Heidi shared her experience with the Software for Humanity (SoftHum) project and similar efforts (see www.xcitegroup.org). The final list of infrastructure tools included: source version control, bug trackers, IRC channels with bots, wikis, planets, blogs, lists, hosting, VNC server, codepad.org, pastebin.org, doodle, piratepad.net.

P.S. POSSE Worcester folks are real, walk, eat, drink beer, and have fun!

POSSE Worcester – Day 3: It’s development time!

June 12, 2010 Comments off

(going back in time as I try to catch up with blogging about the amazing time I had at POSSE Worcester).

Tasks of the day: hack, translate, package, and evaluate pedagogical purpose of Measure activity.

We created a clone repository for Measure. Gary and I tackled a new defect in Measure that is ticketed 1911. The problem we found is that no timing is implemented when sound sampling is chosen for 30 seconds, 1 minute, and so on. The combo box and sampling button had confusing labels and tool tips. Gary made changes in sound-toolbar.py file to rename them and toggle the sampling button tooltip name with start or stop sampling. The correct timing task is left for tomorrow.

I learned about translation in SugarLabs and did some translation for Measure. I first located measure_activity.po file in Honey and use the web interface to translate 39 of the existing 41 strings. I must have omitted to hit the commit button for two of the strings. To type Romanian characters, I used this little tool.

POSSE Worcester – Day 2: Hacking

June 9, 2010 Comments off

Walter Bender from SugarLabs explained the source code of Abacus activity in the Sugar Labs git repository. I have not coded in Python before, and here I had the chance of giving it a try. The task was to add a Decimal abacus to the existing list of seven abacus tools. I modified two files to do that by copying, pasting, and making minor changes to existing code. Having Kristina by my side was a big help. I have also learned about Sugar version control on gitorious.

Mel explained the requirements a Sugar activity must meet in order to be added to a Sugar on a Stick release. To facilitate the formation of teams for the second day deliverables, each of us chose to contribute work pertaining to one ore more of the activity requirements. Mel, Walter, and Peter Robinson have divided same requirements among themselves. I am on a team with Kristina for packaging an activity, with Peter Frohlick for activity translation, and with Aparna for making a case for the activity’s pedagogical purpose.
The activity chosen for our project is Measure.

POSSE Worcester – Day 1: Entropic order

June 7, 2010 Comments off

The 8:30 to 3 schedule, a carefully bulleted agenda, and eight attentive teachers quietly keyboarding at their computers would undoubtedly give the impression that things are in order. In essence, though, it turned out very entropic.  How many times we assure our students that good problem solving process is of an unsettling nature, as we aim at delivering a solution, but with many twists and turns in between? Today, at POSSE Worcester 2010 Day 1, we experimented it on ourselves.

The challenge for me was doing many things at the same time, with no full understanding of what I was doing  or what the tools and means I was using were… as if I didn’t have my head and I was not using my hands.

In the end – defined, arbitrarily, by the closing time of 3 pm, deliverables were orderly and neatly checked in a table on the white board.

Lessons learned:

One thing is certain. Engaging in open source is like learning to ride a bike: can never be forgotten.
