Serving KML and KMZ files in Azure
Crispin – 19 August 2017
Having run my own webservers for a couple of decades and been in total control of the MIME types (aka media types) that could be served, I was caught out after we moved our websites to Azure. KML and KMZ files used by Google maps for map pins and overlays are not served by default.
To fix the issue, I had to add a staticContent element to the web.config file under system.WebServer:
<system.webServer> <staticContent> <mimeMap fileExtension=".kml" mimeType="application/vnd.google-earth.kml+xml" /> <mimeMap fileExtension=".kmz" mimeType="application/vnd.google-earth.kmz" /> </staticContent> ...
After publishing the site with the revised web.config, my overlays re-appeared.
An Azure future
Crispin – 15 June 2017
We've always run our own web servers for hosting since 1998, but since the current ones are now 9 years old and due for replacement we're changing our approach. It's going to be much less work and less risky - in the long-term - to move all our websites to the 'cloud' in the form of Microsoft Azure. In the short-term we have to sort out the migration and this invovles making the technology for all the websites consisitent.
We've already moved our DNS service from our (highly recommended) co-location host Hub Network Systems to dnsmadeeasy. The next step is to migrate the CazMiranda databases to Azure, swiftly followed by the websites. Once we're happy that it's all working, then the DNS switch will be flipped and we can retire the old servers.
Although all the websites will be consistent after 30 June 2017, they won't be using the very latest technology - ASP.NET Core - which would be more appropriate for Azure. It's taken 6 months to get to this point using the older .NET 4.6.2, so transitioning to .NET Core is a job for another day.
Is the future serverless?
Crispin – 11 November 2016
In the past, website hosters like us had to run their own servers with all the IT hassles that entails. The future is starting to look different because of 'container' technology like Docker. Software containers are like shipping containers for applications. You put your application in a container and it can be moved around and/or scaled. This means that it's possible to run a website on premises on something as small as the credit-card-sized Raspberry Pi, a NAS box, an server or off-premises in the cloud.
The cool thing is that it should be possible to move the container between these devices, though the DNS system would have to keep up.
So is it really serverless? All software has to run on hardware and if this hardware is on-premises (even a Raspberry Pi) then you have a server to manage. On the other hand, if you are running in the cloud, then the responsibility of managing the server is certainly reduced and maybe eliminated. Let's hope.
Have your credentials have been compromised?
Crispin – 25 September 2015
Troy Hunt is an Australian web security specialist, speaker and trainer who has an interesting blog and related website haveibeenpwned . From this I’ve discovered that, along with 152 million other people, my Adobe log-on credentials have been compromised.
If you too try the haveibeenpwned website and you find that your credentials have been compromised, then it would be a good idea to at least change your password for the appropriate account. You may be able to delete the account if you don’t need it anymore, but some website owners are very reluctant to actually do that. But it’s also possible that their PCI-DSS validation may depend upon not deleting absolutely everything.
Smartphones overtake laptops as preferred internet device
Crispin - 6 August 2015
If anyone needs a reason for converting their website to be mobile friendly, this is surely it. Smartphones have now overtaken laptops as the preferred method of getting online in the UK.
My own mobile data use has been increasing a lot recently since my SIM contract is essentially unlimited. It means that I make use of otherwise dead time at airports, on trains or as a car passenger. I'd become concerned about the security aspects of logging on to wi-fi hotspots all over the place. The mobile data contract took away much - it could never be all - of the worry of third-party networks.
Website performance is the next issue to solve
Crispin - 14 April 2015
After the so-called Google ‘Mobile-geddon’, the next issue for websites is going to be their download peformance. In truth, it’s always been an issue but high-speed broadband has masked the problem. However this problem has now reappeared on 3G and 4G mobile connections because the device user may not be getting anything like headline connection speeds. Coupled with this is the fact that people may be paying by the megabyte for data.
Template-based websites (eg WordPress) are code-heavy and tend to make a lot of external references, all of which slow things down. This could (and should) change if the template-based website developers tighten up their code, but it’s quite likley that a lot of website owners won’t upgrade. This opens up an opportunity for those website owners who have or move to performant websites.
Google will be regarding mobile-friendliness as a ‘ranking signal’
Crispin - 16 March 2015 and 26 March 2015
In a blog post titled Finding more mobile-friendly search results on 26 February 2015, Google announced (down the page) that if your website is not mobile friendly then it will be downgraded in the search rankings when the search is conducted on a mobile device. The rollout blog post (see references below) made things a bit clearer.
What does this mean for website owners?
First use the Google mobile friendly test to see if your website passes. If it does, then you will not lose ranking because of this ‘signal’.
On the other hand, if it fails, check to see how much mobile traffic your website received in the web statistics. If it’s a lot and search engine ranking matters to you, then your website will certainly need to be recast as a responsive design. Retrofitting a responsive design to an existing site is sometimes possible, but if the design is more than five years old there’s a good chance it uses a table-based design that won’t be easy to convert.
A better solution may be to take the opportunity to reconsider your marketing objectives in these days where individuals use a range of devices to view your website and also review what’s worked and what hasn’t in the past. Armed with that, go for a website redesign.

It’s harder to multitask on a smartphone than a desktop
Crispin - 4 March 2015
Smartphones are best suited to single task jobs like reading email or checking up on social media. It’s much harder to do something that requires information from multiple sources to be contrasted eg checking flight options from multiple airlines and then correlating that data with train and bus timetables. It’s at times like these that big desktop monitors come into their own.
Even though smartphones are getting bigger (ie phablets) the apps that run on them are single page applications (SPAs) so you can’t arrange each app in a window to suit the task in hand. What this means is that the user has to remember (or note down) all the information that they need to make a decision.
What does this mean as a website owner?
Don’t forget the desktop version of your website, particularly if users are likely to want to scale the page. There has been a rush towards ‘mobile first’ website development which has sometimes meant that the desktop version is just an oversized version of the mobile site. Think more clearly about your users’ needs so that they don’t have to.
We now spend more time communicating than sleeping
Crispin - 17 February 2015
According to this Ofcom report, the average UK adult now spends more time using media or communications (8 hours 41 minutes) than they do sleeping (8 hours 21 minutes - the UK average). It also appears that some six year olds claim the same understanding of communications technology as 45 year olds.
Clearly trends in digital capability are going to affect how people view your website, particularly whether it does enough for them.
Securing all websites - for free!
Crispin - 27 January 2015
Google has given notice that it's going to give brownie points to websites that use a secure certificate. For smaller websites this would have been a bit of a problem because of the cost in time and money of acquiring and installing a certificate.
Fortunately help is at hand in the form of Let's Encrypt brought to you by some big names in the industry. It's providing secure certificates for free. It will be available from mid-2015.
