The Case Against Consistency in Code

Published 2021-05-18 by Kevin Feasel

Mark Seemann takes a contrarian approach:

In this essay, I use the term coding style to indicate a set of rules that governs how code should be formatted. This may include rules about where you put brackets, whether to use tabs or spaces, which naming conventions to use, maximum line width, in C# whether you should use the var keyword or explicit variable declaration, and so on.

As already stated, I can appreciate consistency in code as much as the next programmer. I’ve seen more than one code base, however, where a formal coding style contributed to ossification.

Read on for the argument. In this case, the language is C# but the concept applies across the board.

Column-Level Encryption in SQL Server

Published 2021-05-18 by Kevin Feasel

David Fowler takes us through a venerable (here by which I mostly just mean “old”) technique for encryption in SQL Server:

SQL Server gives us a few different options when it comes to encryption and I’m going to take a look at each of them at some point in this series but in this first post in the series I want to look at column level encryption.

Before we can even start thinking about encrypting our data, there are a few things that we’re going to need to set up first.

Although I joke about column-level encryption, David shows us just how easy it is to implement. It’s quite useful if you have just one or two columns in the database which need to be encrypted at rest and you don’t want to (or can’t) have the application handle it directly.

Grouping Outputs of Pester Tests

Published 2021-05-18 by Kevin Feasel

Shane O’Neill has fun with Pester:

I’ve been working with Pester v5 lately.

Pester v5 with PowerShell v5 at work & Pester v5 with PowerShell Core outside of work.

There are quite a few changes from Pester version 3, so it’s almost like learning a new language… except it’s based on slang. I think that I’m speaking eloquently, and then I’ve suddenly insulted someone and Pester no longer wants to play nice with me.

Read on to see how to make those Pester outputs look a lot nicer.

Running SQL Server Containers from Scratch

Published 2021-05-18 by Kevin Feasel

Andrew Pruski tells us there is no spoon:

I’ve been interested (obsessed?) with running SQL Server in containers for a while now, ever since I saw how quick and easy it was to spin one up. That interest has led me down some rabbit holes for the last few years as I’ve been digging into exactly how containers work.

The weirdest concept I had to get my head around was that containers aren’t actually a thing.

Containers are just processes running on a host that implement a set of Linux constructs in order to achieve isolation.

So if we know what constructs are used…shouldn’t we be able to build our own container from scratch?

Read on as Andrew breaks out the three necessary constructs and dives into it.
