HI WLUG, Thanks, Tim, for sending that notice to the WLUG membership. Specifically, I will be discussing Broadband-Hamnet (trademark), which is a mesh network designed by amateur radio operators, but can be used by mere mortals :-) as well. One can reflash many versions of the the Linksys WRT54G with this software and create your own mesh network, as has been done in Austin, TX and I believe Seattle, WA. Also, the Ubiquiti hardware can be used. I will have slides and a few Linksys boxes to demonstrate the concept. Feel free to bring your laptop to connect to the demo network. One can connect via an ethernet cable (bring your own) or wirelessly. For more information: http://www.broadband-hamnet.org I look forward to seeing you at the meeting, and joining you afterwards for pizza.

Re: Reminder!!! Meeting tomorrow night! Topic: Nix

by John Stoffel

Hey guys, What a great meeting last week! A big shout out to Xavier for doing his presentation on NixOS! Hopefully Tim will be able to share the links to the slides and other info. We talked about: NixOS - A tool and environment for building systems in a deterministic manner. Sorta like Ansible, or Puppet, or Chef, or Salt or cfengine (old school!) or Terraform. But with it's own twist on how it keeps a hash pointing at the version you have, so you can mix-n-match tools versions easily. nushell (https://www.nushell.sh/) - a new shell for Linux and MacOS which includes some PowerShell like features. It looks interesting for sure. But maybe this old dog is too stuck in his ways to change direnv (https://direnv.net/) - A way to have your shell environment updated when you 'cd' into a directory, so that you don't have to remember what environment settings your need when you're moving around and doing work. I wish I had this for my engineers back when I was supporting an ASIC design team, they would have loved this. So who's going to present next month? And what are the feelings of those who are remote? Were you able to follow along and enjoy the talk? Doing both in-person and streamed stuff is tough at times, and I feel like we're not paying enough attention to those who try to comment from remote connections. Cheers, John

Announce: WLUG Meeting Wed 4/10 7PM Jim Gettys on Internet buffer bloat

by Chuck Anderson

Hi folks, The next Worcester Linux Users' Group (WLUG) meeting will be held at its regularly scheduled time: the 2nd Wednesday of the month, which is Wednesday, April 10, at 7PM. The location will be the WPI Campus Center, Mid-Centry Room 331. This month we will have Jim Gettys from Bell Labs talk about Internet buffer bloat. "Internet buffer bloat, by Jim Gettys (Bell Labs) VOIP and teleconferencing often perform much more poorly on today's Internet than the Internet of a decade ago, despite great gains in bandwidth. Lots of fiber, cheap memory, smart hardware, variability of wireless goodput, changes in web browser behaviour, changes in TCP implementations, and a focus on benchmarking Internet performance solely by bandwidth, and engineer's natural reluctance to drop packets have conspired to encourage papering over problems by adding buffers; each of which may introduce latency when filled. The mistaken quest to never drop packets has destroyed interactivity under load, and often results in actual higher packet loss, as TCP's congestion avoidance algorithms have been defeated by these buffers. The lessons of the "RED manifesto" of 1997 have been forgotten or never learned by a new generation of engineers." Wednesday, April 10, 7:00 - 10:00 PM WPI Campus Center, Mid-Centry Room 331 I will also be raffling off some more items. Afterwards, we will go out for pizza. See you there, Chuck President, Worcester Linux Users' Group http://www.wlug.org/

Re: [Wlug] The speaker for the February meeting has been lined up!

by Frank Sweetser

I've been watching the whole software defined network mania fairly closely, and while I honestly don't even know what a presentation about it would look like, I'd always be happy to just chat for a while about if it there's interest.

"interesting" KVM currently in my server rack. It's two nonfunctional KVMs kludged together to make one functional KVM with no docs and no monitor. One of the switches only has a functional switch, and one of the switches only has a functional keyboard, with a COTS Dell monitor essentially gaff taped on top. In general though, I'd love to see a list of equipment up for grabs! --cs

That synology is nice, enough grunt to run a fair amount of compute on it.
