Excel innovation // Microsoft announces Lambda

This week Microsoft announced the introduction of Lambda, transforming the way you create user-defined functions in Excel. It's no longer necessary to use VBA to create user-defined functions. The real biggie is this: Excel can now do any calculation. There's no more 'You should use package X because Excel can't do that'. If you want to know why this is such a big deal, Iain Morrow, CTO at Gridlines, wrote this blog post discussing the implications.

Reviewing financial model outputs

There are two sides to the financial modeller's role. Firstly building the model and then interpreting and making sense of the outputs. Alan Samuels at Amberside Advisors published this article with useful tips for reviewing financial model outputs. There’s also a helpful section on the pitfalls of using a financial model for a purpose it was not designed for.

The Data Loom by Stephen Few

Although now retired from formal teaching, Stephen Few continues to publish useful and relevant books on data and visualisation. The theme of his latest book, The Data Loom, is that current trends in sexy data distract from data sense making. He argues that we rely too heavily on learning the latest tools and fail to focus on developing the skills needed to make sense of data. The Data Loom is a short, concise and well written book. It's one that I can already tell I'll continue to come back to repeatedly in the future.

"The Recent emphasis on data storytelling has too often reduced data presentation to a cheap set of tricks. Presenting data in ways that are visually or narratively engaging is fine as long as they don’t compromise clarity and truth. We achieve clarity and communicate truth by focusing primarily on substance, not on style." - Stephen Few, The Data Loom.

And finally . . . The Smell of Data

The Smell of Data project is a device to alert internet users to data leaks on personal devices using smell. The project is inspired by the scent that's added to natural gas to provide a sensory alert when there is a leak. The device recognises when you visit an unprotected website on an unsecured Wi-Fi network or Hotspot. The scent dispenser releases a puff of the Smell of Data as a warning signal.
