Scan of an old document with the quote highlighted.

Yet more MSc yak-shaving. I'm currently reading Melissa Schilling's book "Strategic management of technological innovation". In a passage talking about customers' resistance to new inventions and the destruction of domain knowledge, it talks about the invention of the Dvorak keyboard. Supposedly better than the QWERTY keyboard - but ignored by the majority of customers. August…

Where is the original "Overview of SHARD" paper?

A citation in a modern paper.

One thing I'm finding extremely frustrating in academia is the number of people citing papers which don't seem to actually exist. As part of a data analytics class, I'm learning about "database sharding". That is, the process of splitting data between multiple machines. But where does the term come from? Wikipedia - the source of…

Animated TreeMaps in R - the hard way

A treemap which show a volumetric view of data.

As I am a bear of very little brain, these are notes to myself on my slightly shonky process for creating animated TreeMaps in R. The aim is to end up with something like this: Generate the images Getting the data is left as an exercise for the reader (sorry!). This loops through the data…

What's the origin of the phrase "we shouldn’t just be pulling people out of the river. We should be going upstream to find out who’s pushing them in"?

Dr. Reginald Lourie, Chairman of the President's Commission on the Mental Health of Children, tell the story of several men who saw a child in the river, drowning. They rushed out and rescued him. Suddenly, while applying artificial respiration, they noticed there were two more children in the river and they rushed out and saved them. Then there were four more children, then eight and 16. They began calling tor help and marshalling greater resources to form a human chain to save the children who were drowning in alarmingly increasing numbers. At last one of the men broke away from the group on the bank and walked away up the river. The others yelled. "Where are you going? You have to help us save these children "The hell with that," he replied, "I'm going upstream to see who's pushing them in,"

More yak-shaving for my MSc. A book I read was discussing data pipeline problems. How so much of the work of ETL is cleaning up crappy data and reformatting it to something useful. We should be going to the source of the data, the book suggested. Rather than wasting time cleaning - get better at…

A pet cat typing on a computer keyboard.

As part of my MSc, I'm getting a few lessons in technologies I'm not familiar with. I've found some of these lessons extremely confusing - even when I'm proficient in the language. Here's an example of a coding fragment from one of the tutorials in the R language. Let me explain everything that I think…

Multicoloured Grid.

I'm doing an apprenticeship MSc in Digital Technology. In the spirit of openness, I'm blogging my research and my assignments. This is my paper from the Technical and Digital Leadership module. I think it is fair to say I didn't get on too well with it. I found it very focused on American companies -…

Zotero Citations to Markdown Links via CSL

Zotero logo.

I use Zotero to manage my references. Instead of in-text citations of (Smith, 1984) - I want that to be hyperlinked to the academic paper referenced. For example ([Smith, 1984](https://doi.org/.....)) This is possible, if you're willing to hack around with CSL - the Citation Style Language. Here's a fragment of CSL that I've adapted from…

The basic thesis of the book is this: Our baseball team doesn't have much money to buy new players Which baseball players have the best Statistic X for the lowest price?

Slide saying "It Doesn't fit in Excel".

Welcome to Yak Shaving School! As part of my MSc I'm reading a book about Data Analytics. So I've been chasing down quotes to find their origin. One paper had this popular quote in it (emphasis added): As with many rapidly emerging concepts, Big Data has been variously defined and operationalized, ranging from trite proclamations…

Predicting The Future - What 1981 Got Wrong

A microchip with a British flag on it. Technology and the office of the future There is considerable scope for improving the productivity in offices. The major technological advances which will have an impact on this sector are the low-cost VDU, mass data storage, the digital network and voice command by B.W.Manley

As part of my MSc, I fell down a research rabbit-hole of 1980s "Office Of THE FUTURE!!" articles. Ultimately, I couldn't find a way to include it in my research - so you're getting my cast offs. So, I present to you some choice predictions from "Technology and the office of the future" by B.…
