DaSH Session for June 5

Hi DaSHers,
This week DaSH is going on a road trip! Damien Irvine from the Bureau of Meteorology (and Software Carpentry) is visiting CSIRO and will be presenting a half day workshop on CWSLAB (Climate and Weather Science Laboratory). CWSLab is a new initiative between CSIRO, BoM, the Centre for Excellence and others to solve the problems associated with data duplication and having multiple people create code to do the same thing. As part of Damien’s workshop he has invited DaSH to come along for a 30 minute demonstration of CWSLab (9 – 9:30).

This should be a great chance to see a new initiative that may be very useful and important to all researchers accessing and using climate model output in the months and years ahead. I will be going to have a look, so am happy to meet other DaSH people in the IMAS foyer at 8:50 so we can road trip together. Otherwise the demonstration is in the Derwent Room at CSIRO, starting at 9:00.

DaSH Session for May 29

Hi DaSHers,
This week DaSH continues on its recent Q&A inspired theme: you bring along some questions, others in the session provide the answer. Last week we had some good conversation around a few issues, and I am hoping this will continue. I promise to have a bigger whiteboard this week, and even an eraser. These sessions are designed to delve into genuine data-related issues that attendees are currently having, so bring along your problems, or your wealth of experience and opinion, and let’s see what happens. Even if you don’t have an issues, such sessions are a great way to learn more about data analysis and to find out what other people in the building (and elsewhere) do when they are at their desk.

If you have contact with students (honours or even undergrad) then please encourage them to come along. DaSH should be a great forum for them to learn about data science and the world-leading science that is being done in Hobart.

ALSO: The Software Carpentry sessions have been confirmed for starting on June 26 (for 6 weeks). Advertising in the form of flyers, and posts to social media will be out shortly.

Hi DaSHers,
This week will be another informal DaSH session, so come along with your Data Science related problems, or your keen Data Science mind and lets see if we can make get together. After last week’s session on Fortran, we have also had people asking about netcdf operators and there always seems to be questions on presenting results. This week is a good opportunity for following up on recent presentations, or discussing new topics, so come along and see what happens.

Remember you can keep up to date with what is happening at DaSH each week via our twitter feed (@DataScienceHobart), on Facebook (https://www.facebook.com/datasciencehobart) or the WordPress blog (https://datasciencehobart.wordpress.com/). If you follow the twitter feed then you can part of the live tweeting that has been happening recently, just like Q&A. Or, if you are stuck in a time warp from pre 2004 you could try asking someone.

Stuart

ALSO: Tom and Mike and getting their Software Carpentry sessions together. We will be discussing this in more detail on Friday to give people an idea of what they have planned. Before then though we have a few weeks, so if you want to present some new analyses, or have an idea for a topic, then let me know.

And don’t forget that the Faculty of Health will be running a workshop on Practical Bayesian analysis with Bayes Factor on June 15. This is a free course for UTas and CSIRO staff and students. Bayesian analysis has become a standard, if not dominant, tool among statisticians. It has many advantages over standard practice, including conceptual clarity, a principled accounting of statistical evidence and rational belief, and the ability to answer questions of interest to researchers. More details and registration can be found here.

DaSH Session for May 15

Hi DaSHers,
This week DaSH stalwart Roland Warner, formerly of the Australian Antarctic Division, and now an honorary research fellow at the ACE CRC, will be giving an introduction and overview to using the grand-daddy of all programming languages: FORTRAN. Roland’s ambition is to give attendees the basic understanding and skills to read and edit a fortran file as part of their research. It should be a very valuable session for anyone who has anything to do with ocean models or ocean modellers.

Lots of other things are happening in the Data Science space at the moment. From June 12 Tom Remenyi and Mike Sumner will be presenting a 6 week block of sessions that will cover the Software Carpentry course that has been successfully rolled out around the world to give students and researchers alike an introduction to the world of scientific computing. Over the 6 weeks topics covered include the unix shell, SQL, R, Python, Git and best practice in programming. Tell your friends about this one as it will be one not to miss.

The Faculty of Health will be running a workshop on Practical Bayesian analysis with Bayes Factor on June 15. This is a free course for UTas and CSIRO staff and students. Bayesian analysis has become a standard, if not dominant, tool among statisticians. It has many advantages over standard practice, including conceptual clarity, a principled accounting of statistical evidence and rational belief, and the ability to answer questions of interest to researchers. However, due to practical difficulties in implementing Bayesian analyses and the lack of flexible, general purpose software, uptake among non-statisticians has been slower. The BayesFactor and JASP GUI software help to remedy this situation, allowing analysts to perform Bayesian analysis of common designs. This workshop gives a practical introduction to Bayesian analysis, Bayesian linear models, and the BayesFactor software. More details and registration can be found here.

ALSO: Next week is likely to be an informal session again, so get your data science problems ready and bring them along so the group can explore the issues involved. For those who haven’t been to one of these sessions I encourage you to come along, they are a great way to explore problems and learn new techniques relevant to data science.

DaSH Session for May 8

Hi DaSHers,
This week, regular DaSHer Jim Vaughan, from Vaughan Computer Software Solutions, will be presenting a session on SQL (structured query language) for data analysis. Jim will give an introduction to relational database management systems and the use of SQL to retrieve, manipulate and analyse data. The talk will cover basic SQL commands, joining tables and aggregate functions, with an emphasis on how to use SQL for scientific and engineering solutions.

ALSO: Next week Roland Warner will be giving us an introduction and overview of the grand-daddy of programming languages: Fortran. Roland’s aim is to equip attendees with the basic understanding and skills to read and edit a fortran file as part of their research. The kick off date for our software carpentry sessions is now set for June 12. More details on what this means will be coming in the next week or so.
