The other day I faced this problem - server was not automatically renewing Let's Encrypt certificate:   produced an unexpected error: Problem binding to port 443: Could not bind to IPv4 or IPv6..

In most cases make sure that the webroots .htaccess file still contains this section "Rules to correctly serve gzip compressed CSS and JS files". Certain default web server configurations (nginx) do not gzip HTTP/1.0 requests. If you are using cloudfront you will have to add metadata to the .gz files. There are some other options if using cloudfront. For Nginx…

I felt very enthusiastic once Amazon announced OneLink, it seemed like a missing puzzle to serve international customers and boost earnings as an Amazon associate.

In today's article, I'll share my experience how I managed to verify my age for Skype account. It all started that one day I was not able to login to my skype account, which I have been using for more than 10 years already.  It turned out  Skype / Microsoft thought I'm a child, as apparently in my Skype account I had entered my birth year as 2008. Now back in 2008, it didn't seem an issue. Since Microsoft acquired Skype back in 2011, apparently, some new rules have been pointed out and it was…

I believe the last time I have seen an actual fax machine in work was back in 1994. Now 24 years later at one stage I thought, it would be good if I would have a fax machine in 2018.
