Libre Office turns six

On September 28th, 2010, The Document Foundation was announced. The last six months, it feels, have just passed within a short glimpse of time. Not only did we release three LibreOffice versions within three months, have created the LibreOffice-Box DVD image, and brought LibreOffice Portable on its way. We also have announced the LibreOffice Conference for October 2011 and have taken part in lots of events worldwide, with FOSDEM and CeBIT being the most prominent ones.

People follow us at Twitter, Identi.ca, XING, LinkedIn and a Facebook group and fan page, they discuss on our mailing lists with more than 6.000 subscriptions, collaborate in our wiki, get insight on our daily work in our blog, and post and blog themselves. From the very first day, openness, transparency and meritocracy have been shaping the framework we want to work in. Our discussions and decisions take place on a public mailing list, and regularly, we hold phone conferences for the Steering Committee and for the marketing teams, where everyone is invited to join. Our ideas and visions have made their way into our Next Decade Manifesto.

We have joined the Open Invention Network as well as the OpenDoc Society, and just last week have become an SPI-associated project, and we see a wide range of support from all over the world. Not only do Novell and Red Hat support our efforts with developers, but just recently, Canonical, creators of Ubuntu, joined as well. All major Linux distributions deliver LibreOffice with their operating systems, and more follow every day.

One of the most stunning contributions, that still leaves us speechless, is the support that we receive from the community. When we asked for 50,000 € capital stock for a German-based foundation, the community showed their support, appreciation and their power, and not only donated it in just eight days, but up to now has supported us with close to 100,000 €! Another one is that driven by our open, vendor neutral approach, combined with our easy hacks, we have included code contributions from over 150 entirely new developers to the project, alongside localisations from over 50 localizers. The community has developed itself better than we could ever dream of, and first meetings like the project’s weekend or the QA meeting of the Germanophone group are already being organized.

What we have seen now is just the beginning of something very big. The Document Foundation has a vision, and the creation of the foundation in Germany is about to happen soon. LibreOffice has been downloaded over 350,000 times within the first week, and we just counted more than 1,3 million downloads just from our download system — not counting packages directly delivered by Linux distributors, other download sites or DVDs included in magazines and newspapers — supported by 65 mirrors from all over the world, and millions already use and contribute to it worldwide. With our participation in the Google Summer of Code, we will engage more students and young developers to be part of our community. Our improved release schedule will ensure that new features and improvements will make their way to end-users soon, and for testers, we even provide daily builds.

We are so excited by what has been achieved over the last six months, and we are immensely grateful to all those who have supported the project in whatever ways they can. It is an honour to be working with you, to be part of one united community! The future as we are shaping it has just begun, and it will be bright and excellent.

Top Ten Graphs for Business Analytics -Pie Charts (1/10)

I have not been really posting or writing worthwhile on the website for some time, as I am still busy writing ” R for Business Analytics” which I hope to get out before year end. However while doing research for that, I came across many types of graphs and what struck me is the actual usage of some kinds of graphs is very different in business analytics as compared to statistical computing.

The criterion of top ten graphs is as follows-

1) Usage-The order in which they appear is not strictly in terms of desirability but actual frequency of usage. So a frequently used graph like box plot would be recommended above say a violin plot.

2) Adequacy- Data Visualization paradigms change over time- but the need for accurate conveying of maximum information in a minium space without overwhelming reader or misleading data perceptions.

3) Ease of creation- A simpler graph created by a single function is more preferrable to writing 4-5 lines of code to create an elaborate graph.

4) Aesthetics– Aesthetics is relative and  in addition studies have shown visual perception varies across cultures and geographies. However , beauty is universally appreciated and a pretty graph is sometimes and often preferred over a not so pretty graph. Here being pretty is in both visual appeal without compromising perceptual inference from graphical analysis.

 

so When do we use a bar chart versus a line graph versus a pie chart? When is a mosaic plot more handy and when should histograms be used with density plots? The list tries to capture most of these practicalities.

Let me elaborate on some specific graphs-

1) Pie Chart- While Pie Chart is not really used much in stats computing, and indeed it is considered a misleading example of data visualization especially the skewed or two dimensional charts. However when it comes to evaluating market share at a particular instance, a pie chart is simple to understand. At the most two pie charts are needed for comparing two different snapshots, but three or more pie charts on same data at different points of time is definitely a bad case.

In R you can create piechart, by just using pie(dataset$variable)

As per official documentation, pie charts are not  recommended at all.

http://stat.ethz.ch/R-manual/R-patched/library/graphics/html/pie.html

Pie charts are a very bad way of displaying information. The eye is good at judging linear measures and bad at judging relative areas. A bar chart or dot chart is a preferable way of displaying this type of data.

Cleveland (1985), page 264: “Data that can be shown by pie charts always can be shown by a dot chart. This means that judgements of position along a common scale can be made instead of the less accurate angle judgements.” This statement is based on the empirical investigations of Cleveland and McGill as well as investigations by perceptual psychologists.

Despite this, pie charts are frequently used as an important metric they inevitably convey is market share. Market share remains an important analytical metric for business.

The pie3D( ) function in the plotrix package provides 3D exploded pie charts.An exploded pie chart remains a very commonly used (or misused) chart.

From http://lilt.ilstu.edu/jpda/charts/chart%20tips/Chartstip%202.htm#Rules

we see some rules for using Pie charts.

 

  1. Avoid using pie charts.
  2. Use pie charts only for data that add up to some meaningful total.
  3. Never ever use three-dimensional pie charts; they are even worse than two-dimensional pies.
  4. Avoid forcing comparisons across more than one pie chart

 

From the R Graph Gallery (a slightly outdated but still very comprehensive graphical repository)

par(bg="gray")
pie(rep(1,24), col=rainbow(24), radius=0.9)
title(main="Color Wheel", cex.main=1.4, font.main=3)
title(xlab="(test)", cex.lab=0.8, font.lab=3)
(Note adding a grey background is quite easy in the basic graphics device as well without using an advanced graphical package)

LibreOffice 3.3.2

the latest freest office productivity software in the world.

The Document Foundation maintains its release schedule thanks to a growing and vibrant community of developers

The Internet, March 22, 2011 – The Document Foundation announces LibreOffice 3.3.2, the second micro release of the free office suite for personal productivity, which further improves the stability of the software and sets the platform for the next release 3.4, due in mid May. The community of developers has been able to maintain the tight schedule thanks to the increase in the number of contributors, and to the fact that those that have started with easy hacks in September 2010 are now working at substantial features. In addition, they have almost completed the code cleaning process, getting rid of German comments and obsolete functionalities.

“I have started hacking LibreOffice code on September 28, 2010, just a few hours after the announcement of the project, and I found a very welcoming community, where senior developers went out of their way to help newbies like me to become productive. After a few hours I submitted a small patch removing 5 or 6 lines of dead code… enough to get my feet wet and learn the workflow”, says Norbert, a French developer living in the United States. “In a short time, I ended up removing the VOS library – deprecated for a decade – from LibreOffice, and finding and fixing various threading issues in the process”.

LibreOffice 3.3.2 is being released just one day after the closing of the first funding round launched by The Document Foundation to collect donations towards the 50,000-euro capital needed to establish a Stiftung in Germany. In five weeks, the community has donated twice as much, i.e. around 100,000 euros. All additional funds will be used for operating expenses such as infrastructure costs and registration of domain names and trademarks, as well as for community development expenses such as travel funding for TDF representatives speaking at conferences, booth fees for trade shows, and initial financing of merchandising items, DVDs and printed material.

Italo Vignoli, a founder and a steering committee member of The Document Foundation, will be keynoting at Flourish 2011 in Chicago on Sunday, April 3, at 10:30AM, about getting independent from OpenOffice and Oracle, starting The Document Foundation, raising the capital and the first community budget, organizing developers and other work, and outlining a roadmap for future releases and features.

The Document Foundation is at http://documentfoundation.org, while LibreOffice is at http://www.libreoffice.org. LibreOffice 3.3.2 is immediately available from the download page.

*** About The Document Foundation

Interview Anne Milley JMP

Here is an interview with Anne Milley, a notable thought leader in the world of analytics. Anne is now Senior Director, Analytical Strategy in Product Marketing for JMP , the leading data visualization software from the SAS Institute.

Ajay-What do you think are the top 5 unique selling points of JMP compared to other statistical software in its category?

Anne-

JMP combines incredible analytic depth and breadth with interactive data visualization, creating a unique environment optimized for discovery and data-driven innovation.

With an extensible framework using JSL (JMP Scripting Language), and integration with SAS, R, and Excel, JMP becomes your analytic hub.

JMP is accessible to all kinds of users. A novice analyst can dig into an interactive report delivered by a custom JMP application. An engineer looking at his own data can use built-in JMP capabilities to discover patterns, and a developer can write code to extend JMP for herself or others.

State-of-the-art DOE capabilities make it easy for anyone to design and analyze efficient experiments to determine which adjustments will yield the greatest gains in quality or process improvement – before costly changes are made.

Not to mention, JMP products are exceptionally well designed and easy to use. See for yourself and check out the free trial at www.jmp.com.

Download a free 30-day trial of JMP.

Ajay- What are the challenges and opportunities of expanding JMP’s market share? Do you see JMP expanding its conferences globally to engage global audiences?

Anne-

We realized solid global growth in 2010. The release of JMP Pro and JMP Clinical last year along with continuing enhancements to the rest of the JMP family of products (JMP and JMP Genomics) should position us well for another good year.

With the growing interest in analytics as a means to sustained value creation, we have the opportunity to help people along their analytic journey – to get started, take the next step, or adopt new paradigms speeding their time to value. The challenge is doing that as fast as we would like.

We are hiring internationally to offer even more events, training and academic programs globally.

Ajay- What are the current and proposed educational and global academic initiatives of JMP? How can we see more JMP in universities across the world (say India- China etc)?

Anne-

We view colleges and universities both as critical incubators of future JMP users and as places where attitudes about data analysis and statistics are formed. We believe that a positive experience in learning statistics makes a person more likely to eventually want and need a product like JMP.

For most students – and particularly for those in applied disciplines of business, engineering and the sciences – the ability to make a statistics course relevant to their primary area of study fosters a positive experience. Fortunately, there is a trend in statistical education toward a more applied, data-driven approach, and JMP provides a very natural environment for both students and researchers.

Its user-friendly navigation, emphasis on data visualization and easy access to the analytics behind the graphics make JMP a compelling alternative to some of our more traditional competitors.

We’ve seen strong growth in the education markets in the last few years, and JMP is now used in nearly half of the top 200 universities in the US.

Internationally, we are at an earlier stage of market development, but we are currently working with both JMP and SAS country offices and their local academic programs to promote JMP. For example, we are working with members of the JMP China office and faculty at several universities in China to support the use of JMP in the development of a master’s curriculum in Applied Statistics there, touched on in this AMSTAT News article.

Ajay- What future trends do you see for 2011 in this market (say top 5)?

Anne-

Growing complexity of data (text, image, audio…) drives the need for more and better visualization and analysis capabilities to make sense of it all.

More “chief analytics officers” are making better use of analytic talent – people are the most important ingredient for success!

JMP has been on the vanguard of 64-bit development, and users are now catching up with us as 64-bit machines become more common.

Users should demand easy-to-use, exploratory and predictive modeling tools as well as robust tools to experiment and learn to help them make the best decisions on an ongoing basis.

All these factors and more fuel the need for the integration of flexible, extensible tools with popular analytic platforms.

Ajay-You enjoy organic gardening as a hobby. How do you think hobbies and unwind time help people be better professionals?

Anne-

I am lucky to work with so many people who view their work as a hobby. They have other interests too, though, some of which are work-related (statistics is relevant everywhere!). Organic gardening helps me put things in perspective and be present in the moment. More than work defines who you are. You can be passionate about your work as well as passionate about other things. I think it’s important to spend some leisure time in ways that bring you joy and contribute to your overall wellbeing and outlook.

Btw, nice interviews over the past several months—I hadn’t kept up, but will check it out more often!
