Dynamic Management Views (DMVs) are a significant and valuable addition to the DBA's troubleshooting armory, laying bare previously unavailable information regarding the under-the-covers activity of your database sessions and transactions. Why, then, aren't all DBAs using them? Why do many DBAs continue to ignore them in favour of "tried and trusted" tools such as sp_who2, DBCC OPENTRAN,

Erlang is the result of a project at Ericsson's Computer Science Laboratory to improve the programming of telecommunication applications. A critical requirement was supporting the characteristics of such applications, that include: massive concurrency, fault-tolerance, isolation, dynamic code upgrading at runtime, transactions. Throughout the whole of Erlang's history the development pro

The scenario describes a user sitting down at a computer to check email. One of the messages includes an attached document to be edited. The user clicks the attachment, and it opens in another window. After starting to edit the document, the user realizes they need to leave for a trip. They save the document in its partially edited state and shut down the computer to save energy. Upon re

The modern data stack has evolved rapidly in the past decade. Yet, as enterprises migrate vast amounts of data from on-premises platforms to the cloud, data teams continue to face limitations executing data transformation at scale. Data transformation is an integral part of the analytics workflow-but it's also the most time-consuming, expensive, and error-prone part of the process. In th

Microservices architectures introduce several benefits to the application development and delivery process. Microservices-based apps are easier to build, test, maintain, and scale. They also reduce downtime through better fault isolation. While container-based microservices apps have profoundly changed the way DevOps teams deploy applications, they have also introduced challenges. Kubern

Blazor, A Beginners Guide is intended for developers with some .NET experience. If you're coming from a non-.NET development background, you may learn some .NET basics along the way, but supplemental material around C# and .NET would be of great help to you. The book begins with the author's own perspective on WebAssembly, why it's important to have choices in web development and offers

Software developers work rhetorically to make meaning through the code they write. In some ways, writing code is like any other form of communication; in others, it proves to be new, exciting, and unique. In Rhetorical Code Studies, Kevin Brock explores how software code serves as meaningful communication through which software developers construct arguments that are made up of logical p

This book is a collection of short interviews with 14 prominent individuals from different parts of the world, from Australia to Canada, and of different occupations, from low-level programmers to physicists and musicians, asking them a more-or-less similar set of questions on the following topics: their general attitude to programming, attitude towards and experience with Lisp, stories

Defend Dissent is an introduction to cryptography paired with the social impacts of surveillance and the protective potential of encryption, with a focus on US social movements. Each chapter ends with a story that brings social context to the material - from surveillance used against contemporary US protests to the African National Congress's use of partially manual encryption in fightin

Data science is the process of representing models that fit data. Its goal is to predict future output based on past observations of inputs. In data science, one collects information and interprets it to make decisions. This open book contains two parts, the first is designed to be used in an introductory programming course for students looking to learn Python, without having any prior e
