  • Clone / Copy Bootable USB Keys (TrueNAS or XigmaNAS)

    TrueNAS (formerly FreeNAS) and XigmaNAS are great NAS servers for your Home and/or Office environment. One of the problems is that both of these NAS Servers recommend you to use a USB key to boot and then configure your drives as storage only in whatever RAID or Non-RAID configuration you wish. What if the USB boot device fails? It would be nice if you could make a copy of the USB bootable device, and to do so automatically rather than making them manually. You can! Thanks to the script we have developed using the dd command.

  • Zoom 32 Bit / 64 Bit

    I am not sure if you noticed, but there are both 32 bit and 64 bit versions of the Zoom Meetings App. As most know that any 64 bit version of any app will run better and more efficient than a 32 bit version. A 32 bit version of a program can only access 4GB RAM. Therefore if you have a computer with more than 4GB on your system (e.g 8GB, 12GB, 16GB + or more), the 32 bit program will not access it.

  • Checking your Domain Reputation

Now most organizations have moved their mail servers offsite and now have their email hosted with Google Workspace, Microsoft 365 or some other hosting platform. Your Domain's Reputation is still very important as you are now sending email over an IP shared with other senders. Now that we see greater implementation of IPv6, we are seeing an even greater shift in how email reputation by various mail servers is calculated.
