Building a secure data solution using Azure Data Lake Store (Gen2)

Building a secure data solution using Azure Data Lake Store (Gen2)

Carmel Eve

In this blog we discuss building a secure data solution using Azure Data Lake. Data Lake has many features which enable fine grained security and data separation. It is also built on Azure Storage which enables us to take advantage of all of those features and means that ADLS is still a cost effective storage option!This post runs through some of the great features of ADLS and runs through an example of how we build our solutions using this technology!

Speaking at NDC London: Combatting illegal fishing with Machine Learning and Azure

Carmel Eve

In January 2020, Carmel is speaking about creating high performance geospatial algorithms in C# which can detect suspicious vessel activity, which is used to help alert law enforcement to illegal fishing. The input data is fed from Azure Data Lake Storage Gen 2, and converted into data projections optimised for high-performance computation. This code is then hosted in Azure Functions for cheap, consumption based processing.
Troubleshooting "NotImplemented / Access is denied" error when integrating Azure App Service with Azure Virtual Network (VNet)

Troubleshooting "NotImplemented / Access is denied" error when integrating Azure App Service with Azure Virtual Network (VNet)

Ed Freeman

Are you configuring your Azure App Service to use a VNet? The regional VNet integration for an Azure App Service is a preview feature, and so comes with some quirks. One of the documented limitations of this preview feature is that "The feature is only available from newer App Service scale units that support PremiumV2 App Service plans." This has interesting implications as to how you need to deploy your App Service, otherwise you could end up with a rather perplexing pattern of errors. Read about how we came about this error, and how we ended up fixing it.

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. They can be used for on-the-fly code generation; building DSLs, and producing high performance computational algorithms. I'm trying to gather evidence about how you are using them, to make a case for future investments in the Expression Tree subsystem in .NET Core / .NET 5.0

Demystifying machine learning using neural networks

Demystifying machine learning using neural networks

Carmel Eve

Machine learning often seems like a black box. This post walks through what's actually happening under the covers, in an attempt to de-mystify the process!Neural networks are built up of neurons. In a shallow neural network we have an input layer, a "hidden" layer of neurons, and an output layer. For deep learning, there is simply more hidden layers which allows for combining neuron's inputs and outputs to build up a more detailed picture.If you have an interest in Machine Learning and what is really happening, definitely give this a read (WARNING: Some algebra ahead...)!
