DaSH Session for May 1

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 beautiful music together. Recently people have asked for tutorials on Fortran, netcdf operators and more. This week presents a good opportunity for discussions surrounding such topics (and others) and anything else people bring to the session.

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.

ALSO: Next week it looks like Tom and Mike will be presenting a Software Carpentry workshop. Stay tuned for further details.

DaSH Session for April 24

Hi DaSHers,
DaSH is slowly getting smarter. Last week I told you all about dumb things you could do (or not do) with data, this week Rowan Trebilco from ACECRC will tell you about “not so dumb things to do when presenting data”. He plans to give a quick overview of some principles for making good data graphics followed by some hints for generating publication quality figures using base graphics in R.

Unfortunately Rowan has no theme song, but this is stuck in my head at the moment…

DaSH Session for April 17

Hi DaSHers,
This week DaSH is going dumb: I will be giving a talk titled “Dumb things with data”. If you want to learn from my (and others) mistakes in order to data analysis techniques, or you just want to laugh at out collective foolishness, then come along. I will be giving examples of how easily data analysis can go wrong if you are not paying attention and how, sometimes, completely unreasonable manipulations can lead to completely reasonable (but wrong) results.

Even better, this session has a theme song. Check it out below…

Hi DaSHers,
This week’s DaSH session will be a hands on introductory tutorial on how to use everyone’s favourite (???) text editor: ViM. Tom has sent through some pre-watching and a list of files to download for tomorrow’s DaSH Session on ViM (see below). I strongly encourage anyone who is planning to attend to watch the video (if you didn’t catch it during Tom’s talk last year), download the files and try and determine how to start ViM on your own machine (hint: type ‘vi’ or ‘vim’ at a command prompt). We will spend a couple of minutes getting people started on ViM tomorrow morning, but hope to spend the majority of the session actually working through examples. If you are really worried then maybe turn up a few minutes early and we will sort you out.

Bring your own laptop, so you can play on your own device.

Stuart

ALSO: Next week I am hoping to hold a session titled “Dumb things to do with Data” where I will be giving examples of stupid mistakes I have made when manipulating data sets. If you want to laugh at me, or learn from my mistakes, then come along. If you have examples of your own dumb examples that you want to unburden yourself from then bring them along.

Hi All,

here are some materials for the vim tutorial session. If you didnt see the video last time, it would help to watch it first, even if your already convinced you should start using vim (or emacs).

Intro to Vim Video/webcast (Conceptual intro into ‘Why use it?’):

Below is a list of example scripts in my dropbox. I couldnt decide on which, so I chose many. I selected those for a range of programs (that way we have a range depending on who turns up), some of which I hope you find useful in your work.

Some are even really well commented and arranged (I shocked myself reading through them!), others are more typical of my repository…

Example scripts:

DaSH Session for April 10

Hi DaSHers,
This week’s DaSH session will be a hands on introductory tutorial on how to use everyone’s favourite (???) text editor: ViM. As I said last week, ViM’s main claim to fame is that it is installed on pretty much every computer ever made (yes, it is even there on Windows 8). It is also famous for perhaps not being the easiest editor to use, but after 45 minutes playing around with it we are confident anyone will learn to love the beast.

So if you have any plans on using UNIX machines, or a remote computer somewhere that only has a text interface, or even just want to know a bombproof way to edit text files on whatever system you are on then come along and get your hands dirty with ViM.

Bring your own laptop. Tomorrow we will be distributing some example text files and a link to an intro video if you want to get ahead of the group.

DaSH Session for April 10

Hi DaSHers,
Due to tomorrow being Good Friday there will be no DaSH Session. The next session will be Friday April 10, where Tom Remenyi will be encouraging everyone in attendance to get their hands dirty and start using the only text editor that is installed on every computer ever made*: ViM. Mid next week we will be circulating an introductory video to using ViM and a couple of sample documents. Bring your computer to the session and within in 45 minutes you will be confidently* using ViM for all your text editing needs.


Stuart
ALSO: In coming weeks we will be holding a similar introductory sessions on using Fortran, and doing an initial Software Carpentry Session. If you want to learn about other data analysis or generation products then send in a request and we will see what we can do.
