[Sugar-devel] Testing Sugar 0.102 on XO-1
Hi, I've just installed 0.102 on an XO-1 in the office and here are my first observations: * I've tried setting limits for the maximum number of open activities using gconftool as described on the feature page, but they were never honored. I remember that this worked for me before when testing 0.100 on XO-4. Also, limiting activity launches to a single instance isn't working either. * It would be useful if there was a 'deselect all' button when listing software updates in control panel. * I only see Harvest among the available web services. The screenshot from release notes suggests that I should be able to see more than one icon. Is that correct or do do others need to be enabled in some way?

My goal was to make launching E-Paath, a collection of interactive activities based on Nepali curriculum, as easy as possible.

With a shortcut, I launch firefox using Python subprocess library , which then runs flash-based EPaath applications.

That's very encouraging to hear. OLE's next deployment was originally scheduled for end of April, but I've just heard might be postponed by a month or two.

[Sugar-devel] Feedback on using 0.100 in deployment
Hi everyone, Here at OLE Nepal, we are intending to use Sugar 0.100 as the base image for our next XO-4 deployment. Is Sugar 0.100 considered stable now? I've been playing with the latest image a little bit and haven't run into any major issues, so I am inclined to recommend it to OLE. I know AU has been using Sugar 0.100 in the recent XO-4 deployments. Can anyone provide any feedback on using 0.100 in a live deployment in AU or anywhere else? It would be very useful for us at OLE to know if there are any potential issues with 0.100 to be aware of before we deploy it in the field. Thanks in advance for any info.

In my project, I am currently focused on the former point, but I am running into limitations regarding the data stored in the datastore.

Yes, that's a very good point.

I think this is a really important point to emphasize: None of these approaches to evaluation provides the complete picture, but all of these used in aggregate can provide useful insights. Here at OLE Nepal, we already use standardized testing to compare students performance before and after the program launch. We also follow up with teachers through conversations using surveys on regular support visit. I agree with Sameer that supplementing those with statistical data can make for a much stronger case.

Here is more information about my xo-stats project: The project's objective is to determine how XOs are used in Nepalese classrooms, but I am intending for the implementation to be general enough, so that it can be reused by other deployments as well. Similarly to other projects you've mentioned, I separated the project into four stages: 1) collecting data from the XO Journal backups on the schoolserver 2) extracting the data from the backups and storing it in an appropriate format for analysis and visualization 3) statistically analyzing and visualizing the captured data 4) formulating recommendations for improving the program based on the analysis. Stage 1 is already implemented on both the server side as well as the client side, so I first focused on the next step of extracting the data. Initially, I wanted to reuse an existing script, but I eventually found that none of them were general enough to meet my criteria. One of my goals is to make the script work on any version of Sugar. Thus, I have been working on process_journal_stats.py, which takes a '/users' directory with XO Journal backups as input, pulls out the Journal metadata and outputs them in a CSV or JSON file as output. Journal backups can be in a variety of formats depending on the version of Sugar. The script currently supports backup format present in Sugar versions 0.82 - 0.88 since the laptops distributed in Nepal are XO-1s running Sugar 0.82. I am planning to add support for later versions of Sugar in the next version of the script. The script currently supports two ways to output statistical data. To produce all statistical data from the Journal, one row per Journal record: process_journal_stats.py all To extract statistical data about the use of activities on the system, use: process_journal_stats.py activity The full documentation with all the options are described in README at: https://github.com/martasd/xo-stats One challenge of the project has been determining how much data processing to do in the python script and what to leave for the data analysis and visualization tools later in the workflow. For now, I stopped adding features to the script and I am evaluating the most appropriate tools to use for visualizing the data. Here are some of the questions I am intending to answer with the visualizations and analysis: * How many times do installed activities get used? How does the activity use differ over time? * Which activities are children using to create files? What kind of files are being created? * Which activities are being launched in share-mode and how often? * Which part of the day do children play with the activities? * How does the set of activities used evolve as children age? I am also going to be looking how answers to these questions vary from class to class, school to school, and region to region. As Martin Abente and Sameer mentioned above, our work needs to be informed by discussions with the stakeholders- children, educators, parents, school administrators etc. We do have educational experts among the staff at OLE, who have worked with more than 50 schools altogether, and I will be talking to them as I look beyond answering the obvious questions. For visualization, I have explored using LibreOffice and SOFA, but neither of those were flexible to allow for customization of the output beyond some a few rudimentary options, so I started looking at various Javascript libraries, which are much more powerful. Currently, I am experimenting with Google Charts, which I found the easiest to get started with. If I run into limitations with Google Charts in the future, others on my list are InfoVIS Toolkit (http://philogb.github.io/jit) and HighCharts (http://highcharts.com). Then, there is also D3.js, but that's a bigger animal. Alternatively or perhaps in parallel, I am also willing to join efforts to improve the OLPC Dashboard, which is trying to answer very similar questions to mine. I am looking forward to collaborating with everyone who is interested in exploring ways to analyze and visualize OLPC/Sugar data in a interesting and meaningful way.
