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. (One little teaser - a good segment of it involves running Linux directly on enterprise class network gear!)

"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

Re: Meeting THIS WEEK, July 10th, 2025! Topic: ?TrueNAS? Pi Kiosk displays?

by Tracie Winslow

I have a pihole but I've been meaning to set one up on my Linux mini-pc instead. Want me to bring my Linux mini-pc and show how to set up a pihole and use it? *"For a long time it seemed to me that life was about to begin - real life. But there was always some obstacle in the way, something to be gotten through first, some unfinished business, time still to be served, a debt to be paid. At last it dawned on me that these obstacles were my life. This perspective has helped me to see there is no way to happiness. Happiness is the way. So treasure every moment you have and remember that time waits for no one."*- Souza On Tue, Jul 8, 2025, 6:01 PM Tim Keller via WLUG <wlug(a)lists.wlug.org> wrote: > Sure!! > > Another topic that came up in a side channel is what is involved in > setting up a pihole. > > On Tue, Jul 8, 2025 at 2:05 PM Kevin Harrington via WLUG < > wlug(a)lists.wlug.org> wrote: > >> I would like to do a proper introduction to CaDoodle now that it's >> released as beta! >> >> On Tue, Jul 8, 2025, 1:31 PM Tim Keller via WLUG <wlug(a)lists.wlug.org> >> wrote: >> >>> Hey Everybody! >>> >>> We've got a meeting this week! >>> Date: July 10th, 2025 @ 7PM >>> Location: Technocopia, 44 Portland St. Worcester MA >>> <https://www.google.com/maps/search/44+Portland+St.+Worcester+MA?entry=gmail…> >>> . >>> Virtual Location: https://meet.jit.si/WlugMA >>> >>> Topic: I could talk about TrueNAS if people were interested in that, >>> otherwise, this might be a bit of a freeform meeting.

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