Sitecore, C# and web development
I kicked off this series last week with a look at what PowerShell DSC is. This week I'm going to look at scripts you can use for basic configuration of Windows itself for a hypothetical development environment. I'll cover basic Windows features, a few issues you might encounter and helpful tweaks like being able to disable IE's "enhanced security" mode if you're working on a server.
I've written before about approaches to automating the install of Sitecore instances via PowerShell, but recently I've been working upgrading this process to set up entire servers. As part of this research I've been working on how to move the scripting over to PowerShell Desired State Configuration – Microsoft's framework for automating the configuration of servers. Having got to a position where the scripts are working and I can turn a plain copy of Windows Server into a functioning Sitecore box, I thought I'd shared an explanation of the tools and how it can be used for Sitecore development environments.
I'm going to break this up into a series of posts, as it's quite a big topic. This week is a bit of an introduction to DSC and my goals for it:
I don't have anything technical to write about this week, as all my time has been taken up with a trip to New Orleans for the Sitecore MVP Summit**1 and the SUGCON NA user group conference**2 . So instead of the usual code, there are a few things about these events I'd like to discuss...
I'm in the middle of preparing a talk for an upcoming Sitecore user group on the subject of using PowerShell DSC for Sitecore installs. (I'll post a write up of the talk after I've given it) And one of the things I've discovered is that once you get into the guts of it, using configuration variables alongside Script Resources can be a bit confusing.
So, for the benefit of my future self (I'm bound to forget this as I am taking time off from my preparation to head over to the US for this**1 and this**2 ) I'm writing down what I've worked out...
This week I've spent a bit of time trying to knock up a quick demo of how Coveo can cope with searching in languages other than English. However, it's just my luck that the language I have to demo in is not on the list of languages supported out-of-the-box: Welsh. Hence I've been investigating how to customise the UI so that things look right for my demo. Turns out there are a few things to think about:
Previously, I've written a few posts (here, here and here) about automation approaches and PowerShell scripts I was experimenting with for installing developer instances of Sitecore 6. It seems about time that I checked out how that scripting work copes with newer versions of Sitecore...
As I slowly get to move from v6.6 era versions of Sitecore onto the more modern releases, one of the topics I've been re-visiting is install automation. In the past I'd looked at PowerShell scripts for installing Sitecore itself, and configuring development sites, but one of the new things to deal with once you move past v7.5 is the need for MongoDB. Turns out, that's pretty easy to automate if you need to:
A while back I had the chance to look into the my initial install issue, I've spent a bit of time looking at Coveo's approach to the faceted search I'd used on some recent projects. Whilst this mostly works really easily, I've spotted a minor shortcoming in the out-of-the-box functionality which needed a quick work around for my scenario to work.
I was having a conversation with a programmer new to C# recently, who was rather confused by something similar to the following bit of code. He'd been looking at the source for a library on GitHub, and he didn't understand why this could run without errors:
To him, it seemed to be risking a
NullReferenceException, as you can't call a method on a null object.
I encountered a strange error last week, while setting up a virtual machine for some testing: Double clicking the Sitecore 7.2 installer would show the "Extracting" dialog, but after a short while it would vanish and nothing else would happen...
