R: ggplot – Plotting back to back charts using facet_wrap

Earlier in the week I showed a way to plot back to back charts using R’s ggplot library but looking back on the code it felt like it was a bit hacky to ‘glue’ two charts together using a grid.

I wanted to find a better way.

To recap, I came up with the following charts showing the RSVPs to Neo4j London meetup events using this code:

2014 07 20 17 42 40

The first thing we need to do to simplify chart generation is to return ‘yes’ and ‘no’ responses in the same cypher query, like so:

timestampToDate 

The query is a bit because…

7 Myths About Great Résumés

When friends find out I work in recruitment they often have a lot of questions.  They might ask for funny stories, the strangest applications I've seen, but it's never that long until I'm asked if I'll look at their own resume.  Sad though it may seem, I don't mind doing this, actually I quite enjoy it.  Almost every time I've done this I hear the same justifications for formatting, length, and content come up again and again.


I'm sure that this advice is always given with the best of intentions to those seeking jobs.  It's folksy, friendly and given in

Java: Determining the status of data import using kill signals

A few weeks ago I was working on the initial import of ~ 60 million bits of data into Neo4j and we kept running into a problem where the import process just seemed to freeze and nothing else was imported.

It was very difficult to tell what was happening inside the process – taking a thread dump merely informed us that it was attempting to process one line of a CSV line and was somehow unable to do so.

One way to help debug this would have been to print out every single line of the CSV as we processed…

A ferramenta mais fácil do mundo. Será?

Dizer que se é a ferramenta mais fácil do mundo, para qualquer que seja o uso, é algo perigoso sempre. Simplesmente pela expectativa gerada no seu público alvo. Pode ser um tiro no pé. Se a ferramenta realmente for boa, serão reviews ampliados por todo o lado. Se ela não cumprir o objetivo, já era também.

Mas qual é o ponto todo?

Quer dizer, fale bem ou mal, mas fale, me ajude a ir por aí.Um produto precisa ter consciência de encontrar e buscar o seu público alvo. Não vai existir unanimidade.

E em não se procurando unanimidade, se 30% das pessoas…

iMessage Not Delivered

If you get this error message on your childs iPad try the following:

Goto Settings -> General -> Date & Time

And turn on ‘Set Automatically’. If it’s already on turn it off and on again.
If you are still stuck go

Settings -> Messages and logout and log back in again.

For some reason this has fixed my kids iPad problems multiple times.

R: ggplot – Plotting back to back bar charts

I’ve been playing around with R’s ggplot library to explore the Neo4j London meetup and the next thing I wanted to do was plot back to back bar charts showing ‘yes’ and ‘no’ RSVPs.

I’d already done the ‘yes’ bar chart using the following code:

query = "MATCH (e:Event)
2014 07 20 01 15 39

The next step was to create a similar thing for people who’d RSVP’d ‘no’ having originally RSVP’d ‘yes’ i.e. people who dropped out:

query = "MATCH (e:Event)
2014 07 20 17 25 03

As expected if people are going to drop out they do so a day or two before the event happens. By including the need…

Neo4j 2.1.2: Finding where I am in a linked list

I was recently asked how to calculate the position of a node in a linked list and realised that as the list increases in size this is one of the occasions when we should write an unmanaged extension rather than using cypher.

I wrote a quick bit of code to create a linked list with 10,000 elements in it:

public class Chains 
{
    public static void main(String[] args)
    {
        String simpleChains = "/tmp/longchains";
        populate( simpleChains, 10000 );
    }
 
    private static void populate( String path, int chainSize )
    {
        GraphDatabaseService db
