You may seen the recent announcement from Microsoft that Xbox is now the first ‘carbon aware’ games console – reducing carbon footprint by optimizing updates and downloads to run at a time when the console can use the most renewable energy.
Given the increasingly power-hungry needs of the worlds data centres, there is huge opportunity to shift workloads in this … Read more “Building carbon-aware software”
Any organisation more than a few years old typically ends up with a pretty diverse set of technology in use, changing over many years. Team members come and go with different skills, motivations and interests. Technologies shift in popularity, industry trends, and therefore in availability of skills, and ongoing support.

Passive ETFs and tracker funds have become common way to achieve a low-cost diversified portfolio across global indices. The proportion to which the biggest greenhouse gas emitters feature in these indices, and correspondingly in my own passive investments bothered me, so I wanted to see what options I had to tackle it.
If you’re just interested in the climate friendly … Read more “Climate friendly investing when you’re using passive ETFs and tracker funds”

At the time, I found it hard to know where to start, especially when it came to finding concrete actions I could take. I’ve learnt a lot since then, so wanted to share some of the amazing organisations out … Read more “Getting started with #techforgood – what I’ve found so far”
At FundApps we had a semi-dynamic data schema, which could be defined by our regulatory team in accordance with the market data required to enforce regulations.
Imagine a table of stock holdings like the below, with potentially millions of rows, and possibly a few hundred column headers. The data was sparse, but with much overlap in data according to the … Read more “Reducing memory consumption for dynamic tabular data”
