Simple background scheduling

Every so often I come across the need for some simple code to schedule a bit of work in the background of an application. Sometimes because a service (for integration tasks, perhaps) needs to kick off processing every so often, or sometimes because some background part of a larger program needs to happen in parallel with the main execution. A common part of these requirements is that the task should run every so often, but two instances of the task should not overlap no matter how long the background processing takes.

A few times I’ve come across projects with subtly broken implementations of this requirement, so I thought I’d write down a simple approach that has worked for me. That way next time I need it, I won’t have to go digging through git repos… Continue reading

Why am I missing my GeoIP data?

I spent some time this week looking at a client site whose analytics data was missing GeoIP information. Since they had a valid license for Sitecore’s GeoIP lookup service, this was a bit confusing. So, continuing my battle to write up all the unexpected scenarios… Continue reading

Minecraft launcher hangs on startup?

I’ve been reinstalling some PCs recently, and one of them is the machine I play games on in front of the TV. My eldest child still enjoys a bit of Minecraft every so often, so I needed to put that back on my freshly formatted machine – but this proved more difficult than I was expecting.

I’m pretty sure I must have encountered this issue before, but since googling failed to find my blog, I seem to have failed to write the solution down last time 😉 So, in order to save my future self working this out for third time… Continue reading

An interesting side effect of compiled views

I read a blog post earlier this week that talked about the benefits of compiling your View files to increase performance in Sitecore applications. Reading that post (which I stupidly failed to keep track of the link to, so can’t reference it now the comments pointed me back to) reminded me of an interesting issue that came up on a project I was looking at recently. If you’re interested in the raw performance of your Sitecore sites, you might want to consider this as well when you’re planning your views: Continue reading

Could there be performance pain in your future?

A few weeks back I wrote about spotting site performance challenges in the patterns you might see in trace data. But over the years I’ve noticed another set of repeating patterns that can be relevant here: Those of how a development team can find itself thinking and acting in the run up to a project hitting problems.

If any of these resonate with you and your team, maybe it’s time to take a step back and think about how you can improve things? Continue reading

Shooting yourself in the foot with a config patch – redux

Sitecore’s config patch files are great. But sadly it’s entirely possible to cause yourself headaches with them. I’ve written before about how it’s possible that small typos can cause big issues. In that style, a colleage brought an issue to me recently which was an interesting new variation on this fun… Continue reading

Now is the time to seriously consider your Content Security Policy

News stories about hacking and malware are depressingly common these days. Here in the UK I think we’ve not really dealt with all the fall-out from last May when parts of our health service (along with many other businesses) were hit by the “Wannacry” ransomware worm. Yet another security incident happened the other day which will get less press coverage (since it’s nowhere near as dramatic) but has bigger implications for us as web develelopers… Continue reading
