Population of Ireland on a 3d scatter plot

The Central Statistics Office in Ireland has published this dataset:



And here is the user guide:


It gives the population of each 1km square of Ireland on census night 2011. It has various buckets, but I have just looked at total population. I used the 3dscatterplot package in R which is very easy to use. 

Here is my code:

cen<-read.csv("COP2011_Grid_ITM_IE_1Km.csv")
install.packages('scatterplot3d')
library(scatterplot3d)
scatterplot3d(cen$CENT_EAST, cen$CENT_NORTH, cen$TOT_P)

and here is the resulting plot



You can see the big cities jumping up there. It needs a lot of polish to avoid things like Cork getting swamped in the 3d projection, but that's it for now.

Building a choropleth map for Irish agricultural data

I wanted to create a choropleth map  using Irish data. The Irish Government has made a large quantity of data available at data.gov.ie. The set I chose was for Bovine TB across Ireland over a number of years. You can get geojson for a variety of countries and Ireland's county boundaries are available. All I had to do was get the data labels to match. In the data some counties are split into 2 parts. I merged and summed these data points to get the choropleth to work with normal county boundaries. You can see the results here . A link to the github is included at the top of the notebook.

AutoCompleteTextView backed with data from SQLite in Android

Image
This is a handy piece of code. As your database gets bigger you can allow the user to pick the correct value by typing. If the db gets very big, you can always increase the threshold, so that the query does not run until there will be a suitably sized resultset returned. Running it at a threshold of 1 is fine for very small resultsets.  Here is the code you need to back your AutoCompleteTextView with a cursor adapter. @Override protected void onResume() { super.onResume(); text = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView1); final AdapterHelper h = new AdapterHelper(this); Cursor c = h.getAllResults(); startManagingCursor(c); String[] from = new String[] { "val" }; int[] to = new int[] { android.R.id.text1 }; CursorAdapter adapter = new MyCursorAdapter(this, android.R.layout.simple_dropdown_item_1line, c, from, to); adapter.setFilterQueryProvider(new FilterQueryProvider() { public Cursor runQuery(Cha...

Using Statistics to Hire Developers

The Interview I was interviewing a developer for a mid level position today and he turned out to be not up to scratch. The CV looked pretty good, but when I dug in with some fundamental Java questions he was found wanting. Not an unusual occurrence, but still costly. It took 30 minutes of my time, his time and a number of other people were involved to get the process to this stage. I wondered if there might be a way to remove some of the candidate CVs from the batch before we do the costly part of interviewing. Spam or Ham Classifying CVs could be considered like the Spam/Ham problem. Apache SpamAssassin is a good example of a spam classifier. It can probably be made to classify CVs - or at least try, but it is written in C, I think and that is not my thing any more. This looks interesting, so I forked it, converted it to eclipse and started the process of making it build with Maven. First I am going to try this out with spam and ham email, then will try it for other text p...
