I am always looking for books that could unlock new possibilities and help me improve my technical skills. TDD is an area where I consider my experience very limited and where I would like to be inspired.
When this book was published just a couple of months ago I saw an interesting opportunity to refresh my knowledge on this subject and check if what I learned so far and what I have done in my professional experience could be improved.

When RaspberryPi 3+ first came out after playing with sensors and an Arduino Uno board for a while, I used it for monitoring wireless and internet connections in different premises. Thanks to the compact size and the low power needed it was the best tool. I thought it would be interesting to know how consistent was the available bandwidth was during the day and eventually know if there were some unnoticed outages happening.
During these years I’ve used similar utilities, but I decided to write and share with you a simpler script that could be implemented quickly and help you to achieve similar results regardless that you run it inside a docker container, virtual machine or raspberry pi.

Last December NIST announced this vulnerability CVE-2019-19781 and soon after that Citrix published this page CVE-2019-19781 – Vulnerability in Citrix Application Delivery Controller, Citrix Gateway, and Citrix SD-WAN WANOP appliance and released a verification tool supporting clients for finding out if they were vulnerable or not: CVE-2019-19781 – Verification Tool
A verification tool is addressed to an IT specialist who works these solutions and needs to quickly assess if the software or appliance is affected by this vulnerability. Continue reading “Comparing Citrix CVE Verification Tool to a one-liner bash script”
I use NMAP frequently and there are many times that I wish to have its functions on different environments. In this case I was interested in finding how many IP were available for capacity on a local network, knowing that all devices on my network have ICMP enabled.
