Technical leaders agree: AI is now a necessity to compete

AI is enabling new experiences everywhere. When people watch a captioned video on their phone, search for information online, or receive customer assistance from a virtual agent, AI is at the heart of those experiences. As users increasingly expect the conveniences that AI can unlock, they’re seen less as incremental improvements and more as the core to any app experience. A recent Forrester study shows that 84 percent of technical leaders feel they need to implement AI into apps to maintain a competitive advantage. Over 70 percent agree that the technology has graduated out of its experimental phase and now provides meaningful business value.

Serverless Split and Process File with Azure Functions

This article covers the implementation of a data ingestion use case, to ingest a big file, process it and load it into a schemaless database. The entire use case is setup over Azure, taking advantage of Azure Storage as the main source for the file dump, Azure Functions to process the data, and Cosmos DB as the final persistence step.

Operations Task Management for Azure Alerts

A few weeks back, a customer asked us for a way to effectively track the alerts that they get from Microsoft Sentinel and Defender for Cloud and ensure resolution. For organizations with an ITIL practice, this work is tracked by logging an Incident or a Problem ticket in an ITSM tool. But some organizations are a lot leaner (no ITIL practice and no ITSM tooling) and simply need something that works.

General availability: SOAP and XML request and response validation

With the release of SOAP and XML feature, you will be able to reduce the API attack surface for SOAP or XML-based REST APIs by blocking or logging ill-formed API requests or responses and admitting only those, whose bodies adhere to the declared XML schema. The validation policy now supports custom schemas in addition to the schemas specified in the API’s definition.

PriorityQueue In .NET 6

I am honestly surprised that after seeing for several years the different implementations of PriorityQueue included internally in Microsoft Frameworks, now they have been exposed publicly, and this thanks to the arrival of .NET 6. In this article, we are going to know the possibilities of PriorityQueue.

Performance Vs. Scalability

Performance and scalability are two related but separate aspects of a system. However, there is a lot of confusion around the two terms, which often leads to architectural mistakes. This article talks about the difference between the two concepts and how to improve them.

Automatic batching support in React 18

React 18 comes with automatic batching support for state updates. This helps in avoiding multiple renders for state updates in promises, setTimeout, setInterval, native event handlers in addition to react event handlers. Thus, we get performance improvement in our React apps out of the box because of automatic batching.

Controlling React API Calls With Hooks

 love React. But there are some aspects of the framework that have previously given me fits. One of those aspects is in the careful controlling of API calls from within a React app.

How many times have you witnessed this scenario?

You load a React app in the browser and, because you're a frontend developer, you find yourself opening the Inspector Tools and looking at the API (asynchronous) calls that are made from the app. That's when you notice something... fishy.

Software Architecture

Bottleneck #01

This article is the first in a series that examines these bottlenecks. In each article we'll look at how startups get into the bottleneck, usually through doing the right things that are needed early in a startup's life, but are no longer right as growth changes the context for ways of working.

John Lewis IT Software Engineering Principles

Through our combined experience of building and releasing software we have discovered and come to value the following principles. These principles are not hard and fast rules but rather some things that we apply and use to guide us on a daily basis. These principles could also be used in a "discovery phase" when selecting a new product to purchase.

The Code Review Pyramid

When it comes to code reviews, it’s a common phenomenon that there is much focus and long-winded discussions around mundane aspects like code formatting and style, whereas important aspects (does the code change do what it is supposed to do, is it performant, is it backwards-compatible for existing clients, and many others) tend to get less attention.

To raise awareness for the issue and providing some guidance on aspects to focus on, I shared a small visual on Twitter the other day, which I called the "Code Review Pyramid". Its intention is to help putting focus on those parts which matter the most during a code review (in my opinion, anyways), and also which parts could and should be automated.
