We hope this video helps accelerate your own CNAB & Porter epiphanies!

Survey: Expression Trees use cases in .NET

Howard van Rooijen

Expression Trees are one of .NET's super powers; but they are hugely overlooked and misunderstood.

The 100 Year Start-up: Embracing Disruption in Financial Services

The 100 Year Start-up: Embracing Disruption in Financial Services

Howard van Rooijen

Hymans Robertson was set up in Glasgow in 1921 and is one of the longest established independent firms of consultants and actuaries in the UK. Hymans Robertson soon realised that the computational requirements of their models exceeded the capacity of their on-premise datacentres and that the most cost effective solution would be to use the cloud to perform their Big Compute. But before they could harness the cloud to help them solve their Big Data problems, the business needed to understand the ramifications of moving to the cloud; everything from regulatory, risk and compliance concerns,  to how their internal Ops team would need to evolve and adapt, and how to deal with moving data from on-prem into the cloud.
