How to map a Synology NAS with Windows 11 that you previously had connected with Windows 10
If you find that PDF files aren’t updating after changes, it could be that they are cached by the browser or a CDN such as Cloudflare.
If you are running on Apache then you can modify the mod_headers block in the /public/.htaccess file to prevent PDF file caching:
<IfModule mod_headers.c> # Blocks Search Engine Indexing Header set X-Robots-Tag "noindex, nofollow" # Prevents PDF File Caching <FilesMatch ".pdf$"> Header set Cache-Control no-store </FilesMatch> </IfModule>

There are many posts around the internet about loading Disqus comments on demand, however, I found many of them either rely on jQuery, try and load the embed.js file via ajax and run into CORS issues or just lack small bits of functionality. So I thought I would put everything together in one gist.
I recently bought a new pc, and was a bit quick to install Windows, create a backup drive and remove the disk to install the larger ssd from my previous computer.
The upshot of that was that, after installing the operating system on the new drive, it wouldn’t activate Windows as I didn’t fully activate it on the first install before making the recovery drive.
In the end, I got in contact with a Windows support person who recovered the activation key from the computer hardware. Which is pretty simple when you know the commands.
To get your key:
Right click on the start menu and select “Command prompt (admin)”
wmic path SoftwareLicensingService get OA3xOriginalProductKey
You should then get your key in the console output.
I recently ran into an issue whilst trying to change the nameservers for a German (.de) domain name. When I tried to point the domain to a whm/cpanel install I got the error ‘Failed to Modify Domain Nameservers: The domain DNS check has failed’.
The reason for this is specific to .de domains.
There are many articles out there on how DNS prefetching works so I will keep it brief.
It works by adding a link to the head of your web page with a relationship of ‘dns-prefetch’ and the url of a domain which holds assets needed for the page to load. That could be a cdn for the site, a social plugin or anything else.
Without prefetching, a browser will render the page top to bottom and when it gets to an asset which needs to be loaded from another domain it performs a dns lookup to find the location of the host and then downloads the assets. By adding prefetching links we are letting the browser know that these domains will be used before the assets are requested. Browsers can then loook up the hosts whilst rendering the rest of the page, cutting out this step when the assets are needed leding to a shorter download time.
This process is non-blocking and will only be performed when possible. For example, on a small page requesting an asset from another site high in the head of the document, it’s likely that the asset will be loaded before there is a chance to prefetch the dns.
The point of this article is to list domains used by common services for easy future reference.
I’ll first start by saying that the title of this book can be somewhat misleading. The author (Mathieu Nayrolles) has written a previous book with the title ‘Instant Magento Performance Optimization How-to’ and from his personal website it looks like the original title for this book was to be ‘Magento Performance Optimization Volume II’ which followed on from that book.
Whilst the optimization techniques in the book are tested on a Magento installation, the same techniques could generally be used on any PHP/MySQL application.
