Web Excursions for June 2019

Statistical Rethinking Winter 2019

GitHub – clauswilke/practical_ggplot2: Step-by-step examples of building publication-quality figures in ggplot2

GitHub – Quartz/bad-data-guide: An exhaustive reference to problems seen in real-world data along with suggestions on how to resolve them.

Chromebook Data Science Chromebook Data Science (CBDS) is a free online educational to help anyone who can read, write, and use a computer to move into data science,

Started studying a book I purchased in February Data Visualization: A Practical Introduction

The book provides students and researchers a hands-on introduction to the principles and practice of data visualization. It explains what makes some graphs succeed while others fail, how to make high-quality figures from data using powerful and reproducible methods, and how to think about data visualization in an honest and effective way.

 Data Visualization builds the reader’s expertise in ggplot2, a versatile visualization library for the R programming language. Through a series of worked examples, this accessible primer then demonstrates how to create plots piece by piece, beginning with summaries of single variables and moving on to more complex graphics. Topics include plotting continuous and categorical variables; layering information on graphics; producing effective “small multiple plots; grouping, summarizing, and transforming data for plotting; creating maps; working with the output of statistical models; and refining plots to make them more comprehensible.

Melbourne by Bike Path

Melbourne by Bike Path – by David Blom
This trail shows the fantastic network of bike trails Melbourne has to offer. What David has worked out is a 600km loop path with no crossovers or up and backs and minimal on-road riding. Its pretty much all bike paths.

Cool … Raspberry Pi 4 is out

Key features:

Prices From Core Electronics (Australia) are:

  • 1GB AUD $59.95 
  • 2GB AUD $66.95 
  • 4GB AUD $94.95

No, we are not getting ripped off in Australia (well, not much). The Australian prices include 10% GST so a straight conversion of the 4GB US prices come to about $80, then you have to add 10% which makes it $88, which is not far from $94.95

The prices in the UK and US are:

  • 1GB – £33 / $35 vs AUD $55.95
  • 2GB – £43 / $45 vs AUD $66.95
  • 3GB – £53 / $55 vs AUD $94.95

What will I use it for?

  • VPN server for my home network
  • Retro Arcade Gaming
  • Media centre, especially since it can decode x265 streams
  • Computer Security test of my network

I purchased the 4gb version ($95), the USB_C power supply and the Pi 4 case

UP Bank

I just heard about a new bank called “Up Bank”, 20 minutes later I had an UP Bank debit card in my Apple Pay wallet.
A fantastical user experience – The future of banking is looking up

Highly likely I will have transferred my business from ING Direct (which I still like) to UP Bank. The only things I don’t like about UP Bank are:

  • No Credit cards (only savings and a transaction account at moment)
  • If you lose your phone, you lose access to your account because there is no web portal (it’s coming soon) The only way you can interact with your account is via the app either on the phone or on a Apple Watch.

But the features offered have sold me, and their roadmap for 2019 has everything I wanted and more.


Been watch a few Korean dramas lately.

 Live 라이브 poster

Firstly, Live 라이브, an 18 episode show about Police

Kingdom킹덤 poster

The second drama, Kingdom킹덤 is a mix of Korean period drama (good) and a zombie movie (very good … seen Train to Busan?)
It has Bae Doonna in it. Season One was worth the time, can’t wait for season two.

Stranger 비밀의 poster

The last drama also stars Bae Doonna and is called Stranger 비밀의

I @love2chiitan

Was watching John Oliver talking about chiitan, so funny … I now follow @love2chiitan on twitter.

Follow @love2chiitan on twitter, pissed myself laughing 🙂

A busy day

I have converted my blog back to a WordPress install from Hugo.
Why ?
I was talking to a PSO (Protective Services Officer) at Melbourne Central. He had recommended WordPress because he uses it to develop web sites for businesses.
He uses Woocommerce and Stripe to set up shopping carts for clients.
He said it was a very flexible solution. He cited examples where client’s sales had increased 5 or 10 fold because allowing credit card payments makes it very easy for people to buy your product.

So good bye Hugo, good bye static sites … hello WordPress.

I spent Most of Friday and the wee hours of Saturday morning getting my wordpress blog up and running on Zuver.

It now has an SSL certificate so the offical URL is

Since I got the Zuver wordpress hosting for less then $10 for a year it will be interesting to see the renewal price, as it seems to have gone up a lot since I purchased mine.

The full retail price was a little less the $50, but the website now talks of similar plans north of $100

Might be worth paying as the system works quite well.
