pfsense 2.4 – running in a Parallels VM 26 April 2018

Posted by David Wilson in General.

I’ve got pfsense version 2.4 running in a Parallels VM!

Because I can!

I did it really because I wanted to check out the GUI in version 2.4. I also did it as a challenge to see what I needed to do in Parallels to setup a VM with more than the default virtual interface.

Installation is actually easy. Download the .iso file from the pfsense web site. Select the AMD architecture.

Decompress the .gz download so that you just hav the .iso file.

Before creating the new VM, you need to configure the interfaces in Parallels.

You can see the Host-Only #2 network. We will be using that as our LAN interface.
You can see the Shared network, we’ll be using that as our WAN interface.
Take a note of the IP Address range.

When you build the VM, you’ll need to assign an additional network adapter.

Note that Network 1 has it’s source network as Shared Network
Network 2 is assigned to the source network of Host-Only #2

Install and build your VM. You may need to stop and start to assign the second network adapter.
See in my screen shot below note the IP addresses assigned.
You will need to add the interfaces and set the IP addresses.

The LAN IP address is .3 as the Mac itself is .2

Access is via Safari on your Mac and in my case is simply

Have fun.

Intuitive data analysis 11 March 2018

Posted by David Wilson in General.

Does your data presentation allow for it to be interpreted intuitively or easily analysed easily to deprive interesting facts? Does the presentation keep your readers/users engaged and wanting more? How you present data can spark interest and questions or turn off your audience all together.

During the KeyNote presentation at the Difinity Conference (http://difinity.co.nz/) in Auckland during February Siva Harinath from Microsoft presented some sample New Zealand data with Microsoft Power BI (https://powerbi.microsoft.com/en-us/) that you could instantly see value and made you want to explore. I set myself an exercise to reproduce the visualisation in Power BI. The output is shown below.

The end of this article contains details on the data source, you can download this yourself and experiment. Microsoft Power BI is also free to download and use on your Windows PC.

Power BI’s interactive features allow you to filter and slice the data in order to help you derive value. For instance selecting one name, David, as shown below changes the graph to the right to show that David was most popular around 1963. The Power BI interface is easy to drive, you can narrow down the time frame using the filters on the left hand side of the page, select only Male or Female, and then further filter on names.

Adding value to data interpretation. When I first setup this visualisation the horizontal bar graph in the middle of the page was sorted by name. It turns out that this simple presentation means it is difficult to explore the data in any meaningful way. Typically you want to explore the most popular names. To be fair the top 10 most popular names are shown in the tree map in the bottom right of the page. I felt that having the horizontal bar chart sorted by the count of most popular names provided significantly more value.

You can further enhance the visualisation by adding a text search filter on name, for now that filter has to be downloaded from the Power BI store (at no cost). Additionally using the time slicer can help make some aspects of visualisation easier to drive.

While Power BI does allow you to very quickly put up a graphs and filters… put some serious consideration into how your users will consume the data.

  • Who will use it?
  • What will they use it for?
  • How will they use it?
  • Can you present the data in such a way that will allow your users to analyse and explore?

I would be interested in seeing your visualisations in Power BI on this data set. How can you maximise the value in this data set?

About the Data. This data is sourced from the New Zealand Government c/- data.govt.nz specifically here: https://catalogue.data.govt.nz/dataset?q=baby+names – If you are going to try this yourself, make sure you download the CSV file.
As the page says “This data set lists the sex and number of birth registrations for each first name, from 1900 onward.”. This is a simple data set that will import into Power BI without any additional data manipulation steps. You can then quickly get started working on the visualisation.

TrafficCamNZ update for iPhone X 2 December 2017

Posted by David Wilson in General.
add a comment

This update will be available via the AppStore soon. [Note this update has been released, along with 1.9.13 which includes a fix for iPad image position on the main screen].

Version 1.9.12.
Adds support for iPhone X.

Landscape goes edge to edge.

There’s a new preference setting to reduce the size of the image so that it comes in under the iPhone X safe areas.

And when that setting is on, the images are letterboxed.

TrafficCamNZ Update v1.9.11 8 October 2017

Posted by David Wilson in General.
add a comment

There’s a new version on it’s way… and will be available shortly.

View on App Store

In this version (1.9.11)

This is a maintenance release that has been largely internally focused. The changes removed code, complicated routines, and quite possibly errors that could have resulted in the odd crash or two. Now it is cleaner and is no where near as complicated. Here is a bit of a summary of the changes:

● Internal changes that improve the reliability when a datafile update is processed
● Internal changes that improve the reliability when deleting cameras
● Internal changes switching from NIB files to Storyboards – this was a big change which should provide more reliabilty and stability
● Improvements to the Map Tab – when you select the Map Tab, and you have allowed your location to be detected, the map will move to you location to show you the cameras around you. In addition there is a handy button on the botton right of the screen to zoom to your location if you move away.
● First time user experience is improved again
● Quite possibly some new icons in a number of places and at x3 resolution too!
● Search bars on the camera list screens work in a much nicer interface way now.
● iOS 11 update

It’s ALIVE 4 May 2017

Posted by David Wilson in General.

It’s been some time since this was last working on recent operating systems.
The good news is that it’s alive and again controlling launchers on MacOS Sierra.
First real test has been successful.

There’s a little way to go before I can think about a release…

TrafficCamNZ – Updated Datafile available 20 April 2017

Posted by David Wilson in General.
add a comment

I have performed a clean up on the camera file that holds all of the cameras you can use in TrafficCamNZ of the Desktop and iOS.
I’ve removed over 1000 cameras that were no longer working… and have been able to add in others from around the world, along with some updates.

I do not have the ability to delete dead camera from your running instance of TrafficCamNZ – this means that only you can remove the dead cameras. If you are using the built in set then you can go to the preferences screen and choose XML Load Only. This will delete all of the existing cameras and load the new camera set from the file on the web. You will have to reset up your favourite cameras.

If you are happy with the set of cameras you have, then an XML Merge will just merge in the new camera data with the old, applying any updates as required.

Thank you for being a TrafficCamNZ user. Some extra good news – There are updated versions of TrafficCamNZ Desktop for MacOS and TrafficCamNZ for iOS on their way. They will be released via their respective AppStores in the next couple of days.
