The Science of Pretty Much Anything (Paul W. Smith)

 

In the late sixties, I spent several summers working in a gas station. I learned how to rebuild brakes, mount and balance tires, and perform basic maintenance and repair tasks. I also pumped gas.

For those too young to remember, these were the days when you would pull into a gas station and someone would pump your gas, check your cars fluids, fill up your tires, and wash your windows. I was also taught to look for opportunities to sell tires, batteries, wiper blades and replacement fluids. Although it was essentially a sales job, it gave me an opportunity to learn some basic auto mechanics which probably saved me a lot of money with my own NCPO (non-certified pre-owned) cars.

NetAlly AirCheck G2 Review: Field Test for Wireless Site Surveys

I thought it would be helpful to cover 2 topics in the write up:

- Thoughts on the Aircheck G2/Air Mapper tool from Netally

- Share wireless site survey tips and tricks that you can use with any tool

NetAlly's Aircheck G2 is a very solid and capable tool that I enjoyed using but like all tools, there is always room for improvement and evolution. As I said in the video, I would give it an 8 out of 10 and quite happy with it.

The Complete Guide to Network Security Threats! (Chen Shem Tov)

 

What are Network Security Threats?

A network security threat attempts to perform unauthorized actions targeted against private, corporate, or governmental information technology (IT) assets. Typically, a network security attack is launched for the purpose of destroying, modifying, stealing data assets.

Network attacks are typically categorized into two main types:
Passive attacks—screen and monitor sensitive information, for the purpose of compromising enterprise security and any integrated customer.Active attacks—modify or completely destroy information found in the network.

Measuring command response times using ptime

 Every time I write about automated testing, batch files and measuring performance, I get quite a bit of emails asking for more details, more tools or if I can help.

One request I get regularly is people asking if I knew of a tool that will measure the time it takes a command to complete a task. Took me a while scouring the internet and testing a bunch of tools.

Packet Loss: What is a primary cause of slow throughput in today’s wide-bandwidth networks?

 

Packet Loss:

Modelling Microbursts and Packet Queues What is a primary cause of slow throughput in today’s wide-bandwidth networks?

Packet loss

How just a few packet losses can have a debilitating effect on throughput is another matter and has been very well studied –

This takes us into the fields of TCP flow control and congestion avoidance.
