I’ve found that things that are free of charge are often not a good deal. TANSTAAFL, or “There ain’t no such thing as a free lunch.” You’re always paying in some way. Maybe the piece of hardware is marked up more to cover the development cost of the “free” software that comes with it. Perhaps […]

I was setting up VMware vRealize Automation’s Active Directory connections the other day and I needed the public SSL certificate for the AD DCs to authenticate correctly. You can use OpenSSL to get that information. I used a Linux shell but this should be do-able from a Mac or with OpenSSL installed on Windows, too. […]

Working at a startup has many pros and cons, but one of the main benefits over a traditional established company is that a startup often gives you an opportunity to build […]

by Andy Carlson How to provide robust monitoring to low-end systems. When running a critical system, it's necessary to know what resources the system is consuming, to be alerted when resource utilization reaches a specific level and to trend long-term performance. Zabbix and Nagios are two large-scale solutions that monitor, alert and trend system performance, […]

Google has released the Google Colab Command-Line Interface to bridge local terminal environments with remote Colab runtimes. This tool allows for the provisioning of high-performance compute resources, such as GPUs and TPUs, directly from a local machine. It facilitates the execution of local Python scripts on remote hardware and the subsequent retrieval of generated artifacts […]

DockSec is an open-source Python tool and OWASP Incubator Project designed to bridge the gap between vulnerability detection and remediation in container environments. It integrates established security scanners including Trivy, Hadolint, and Docker Scout to analyze Dockerfiles and images for security flaws. By correlating findings from these tools, it generates a security score and provides […]

Microsoft is expanding the BlockContentAnalysisServices sensitivity label setting to cover all connected experiences that analyze content in Word, Excel, and PowerPoint.
