It’s never the runtime… (Except when it is)

BugSomething I’ve learned over the course of many years working in IT is that when you hit a difficult to explain problem it’s very easy to say “it’s the runtime’s fault!” or “that’s a compiler bug” to cover for the lack of explanation for your problem. The vast majority of the time, it’s not true though. It’s just a subtler bug in your own work that you can’t see yet.

Every so often, however, it is true. And it turns out the issue I discussed the other week about Sitecore rendering a Razor error when you asked for a media item may well be an example of this. Continue reading

The rise of the machines

I wasn’t at SUGCON this year, but I followed the event on Twitter and have read a few of the write-ups that have been posted since the event. A popular topic this year has been applying machine learning to Sitecore in the quest for ever cleverer personalised experiences. It’s fascinating stuff to read about, and I’m sure it has great potential for the future, but what I didn’t see much discussion of was the possible down-sides of using “AI” for these tasks rather than people making choices. So allow me to put on some comedy horns and play devil’s advocate for a bit… ->

What went wrong with my media?

Edited to add: With help from Sitecore Support, there’s an explanation for what was going on here now.

If you spend your life working with software, you can’t help but collect a few stories of issues that defied your understanding – and I came across a great example with Sitecore recently. I haven’t managed to decide if this is an issue that can happen to others, or whether it was completely specific to the setup of this particular site. But since I got few useful results from Google when I was trying to solve this, I figure it’s worth writing about it just in case someone else sees a similar problem in the future… Continue reading

Chasing down a browser detection bug

A colleague of mine recently hit upon an odd issue with the Sitecore integration for the 51Degrees browser detection service. It worked fine for most of his testing, but raised an exception in some circumstances. Trying to dig into this and create a test to demonstrate the bug kept us amused for a few hours – maybe it will help you to? Continue reading

Those assumptions? You should validate them…

The one thing that is true of every aspect of IT is that it is always changing. And that change means that things you were confident of in the past may no longer hold true.

I was reminded of this while sitting in the pub with some developers recently, talking about querying for items by path in Sitecore. The debate about the best way to do this raged, but a common thread of the debate was that it is often said that the fastest way to find a set of items you needed is via a ContentSearch index. That assumptions has its roots in the time when most sites were using Lucene to run queries, and for queries with more complex matching rules. But does that hold true here?
