Still going strong after all of these years....

The death of tape has been greatly exaggerated

- September 03, 2020

In a recent news article Bloomberg's has reported on the return of reel-to-reel tape into the music market. Ironically, in Information Technology, tape is also maligned and has been assigned to the scrapheap of history like the VCR . In most cases, the alternative of hard disks, also known as spinning rust, is promoted as the only storage solution required.

- February 13, 2021

Attackers look for the path of least resistance. Recently, that path has shifted from enterprise networks to you and your devices for two reasons. First, as we have built more secure software and systems, it has made it harder to attack enterprise networks. At the same time, we have started to access more sensitive information, both personal and professional, on our phones. Read the article here .
