Let’s Encrypt is an incredible, FREE, service that allows you to get trusted SSL certificates for your website. The certs expire every 90-days but what is great is that there are a lot of tools for auto-renewing the certificate without you ever having to touch anything on your server… until that process breaks. Case-in-point: If […]

I have decided to give Ubuntu 17.04 LTS Desktop a go. On a whim I installed it on a laptop I had lying about (being an IT person they tend to proliferate over a given period of time in my office… older units becoming doorstops, newer units lovely “Jenga” blocks and maybe the occasional Proxmox […]

One of most difficult things to find (imho) is information about API and Service URL’s for just about any and all applications. Microsoft is better than some (Dell, I am looking at you…) but it can still require some metaphorical google search back flips to get to the right information. That said… I wanted to […]

On Thursday I released an article detailing how to get Proxmox setup and also how to configure networking with IPv6. However that article got long and I just said I would address the firewall in the future. Well, that’s today because I need to get the configuration stuff written down before I forget. In addition […]

Last year Google proposed marking any and all sites not using SSL in a negative fashion in its Chrome browser. This year they are indicating they plan on moving forward with this: Google Chrome gets ready to mark all HTTP sites as ‘bad’ To clarify what this means for small content creators… an extra ~$100+ […]
