PHP contact form returns 504 gateway error after moving to Digital Ocean
This one had me scratching my head for a while – using php7.0-fpm and the latest nginx on Debian 8 Jessie I was seeing our PHP contact form working correctly but returning a Gateway 504 error upon submission, which was resulting in a great deal of resubmitted forms and error notifications from users.

Checking whether nginx cache is working
Just set up nginx caching and wondering whether it’s working properly? You can check it pretty easily: curl -I URL.goes.here That should return a bunch of information, but the important bit is: X-Proxy-Cache: MISS Well, in this case it’s not working. If it’s working you’ll see a HIT there.

Adobe Photoshop Lightroom 5.7 and Mac OS X – will no longer open
After upgrading Lightroom 5.6 to 5.7, it refused to open with the error: Library not loaded: @executable_path/../Frameworks/asneu.framework/versions/a/asneu This problem stems from the fact that the system drive is a case sensitive file system; in a similar vein, we were recently unable to install Adobe CC on a similar system as it is also…
