IPv6 – Size really does matter

The internet has been around for more than 40 years in some form. It’s outgrown its ability to handle all of the hosts and fortunately, there’s a solution. IPv6 is mature and wide-spread and not only does it increase the address space to 128-bits (up from 32-bits) it is also more efficient for routing and transferring data across the net and it’s better for VOIP and Gaming. In the US, 55% of all internet traffic is over IPv6 and in some other countries it’s much higher. You almost certainly are using it in your home network and your cell phone is likely using it as well.

Join us as Jim McQuillan gets into the history of the internet and discusses IPv4 shortcomings and how IPv6 deals with those issues. Hopefully you’ll come away ready to embrace this technology.

Also, we’ll be doing a short presentation on a Unix/Linux topic. This month we’ll be talking about the xdg-open (Linux) and open (MacOS) commands.

Next Meeting – Tuesday, September 9th, 2025, 6:30pm EDT.

Last month Sharan Kalwani gave an outsanding talk on high performance computing and filesystems. Unfortunately his talk was cut short due to a power failure caused by storms in the area. Sharan has agreed to come back this month and finish up the talk and provide an opportunity for us to ask him some questions.

If you would like to get caught up on his talk, we have the video of the first part:

Also, we’ve got his slide show here: Slide Show

Here’s a re-print of last months announcement:

This month, Sharan Kalwani will be talking about his own direct experiences in High Performance Computing (used to be called Supercomputing in the days of yore).
We produce and consume an awful lot of data (have to keep them CPUs busy!). So over the decades many techniques and implantations grew – which later became the basis for several commercial/enterprise and also foundational tech for cloud based services.
He would like to share the history of high speed file systems and do a quick review of present day storage.

A seasoned scientific, technical and computing professional, Sharan has
spent over 30+ years’ experience in high performance computing,
engineering applications simulation, benchmarking, networking,
operations, technical support and project management.

He is a senior member of IEEE, ACM, SEMCO, ASEI. He has published a book
on the topic: “UNIX and TCP/IP network security”; and is now working on
his second text, about a new computer programming language. He also
serves as one of the writers/editors of the IEEE Southeastern Michigan
Sections monthly newsletter – Wavelengths. He has also served as Vice-
Chair of IEEE Sustech 2023, IEEE Sustech 2022, IEEE SusTech 2021 Global
Conferences and is on the organizing committee for Online Forum for
Climate Change Technologies 2023, 2024 and 2025.
He is the recipient of:
* 2018 IEEE MGA Achievement award and
* 2024 Engineering Society of Detroit (ESD) Anne O. Fletcher Award
for his various contributions towards technical activities.

Also, we’ll be doing a short presentation on a Unix/Linux topic. This month it’ll be the watch command used for continuously running a command and watching the output
