Announce: WLUG Meeting Wed 4/10 7PM Jim Gettys on Internet buffer bloat
by Chuck Anderson 02 Apr '13

02 Apr '13

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/

Thanks, Joel ============================================================== Favorite Android Apps Utilities: I leave these three running.... Llama (rules based phone control) Llama lets you define an "area" by the local cell phone tower ids You can then set logic based rules based upon location and/or time and/or ... Juice Defender Free Avast Antivirus USED DAILY: Swiftkey Keyboard $ 1.99 Aqua Mail Pro (for *all* e-mail accounts) $ 4.95 SugarSync - 5Gb of Cloud Sync (works like dropbox but sugarsync's android is better ) I sync hourly when on WIFI only. Sync documents and all cell photos with my desktop and laptop. Will do digital photos and also files! I use this for favorite PDF files of magazines, and owners manuals for complex items. PowerAmp (for playing MP3 and podcasts ) $3.99 10 band Equilizer is very handy for podcasts with hiss (just drop high and low frequencies down) Elixir2 (system info) Elixir2 Widgets (allowes more and smaller home page icons in widget) Elixir2 Personal Add On (smaller widget icon to include a contact person) DW Contacts and Phone and Dialer (this one does SO much, I mainly like the visuals on contacts & dialer) Astrid - Task list which syncs to website account Pocket - store web pages for later offline reading ConvertPad Convert units & currencies Bubble Find "Level" in multiple directions Brightest Flashlight RealCalc Sci Calculator UltraChron Stopwatch or Countdown Timer AlarmDroid Simple Alarmclock Librivox Download audiobooks from public domain (usu. 50+ years old) A cool app for kids stories (Aesop's, Peter Pan, Alice in Wonderland..)

Handcent SMS - quick & easy text messages Allows customization of fonts and other item I like. YouTube - browser like for Youtube but better/smoother control aCalendar free - better interface, but still uses Android calendar data I sync aCalendar to my gmail calendar and use it for schedule. X-plore File Manager - handles files and photos locally X-plor also does dropbox/sugarsync/googledrive and ftp Once you get "files" to Android with SugarSync, I then need: Adobe PDF viewer Kingsoft Office very good office suite for viewing and editing Ham Radio & Radio Geek stuff: Repeater Book (listing of ham repeaters based upon your location) EchoLink (connect to radios & repeaters around the world via Internet) Scanner Radio (streams audio from scanners worldwide - incl Worcester F & P & EMS) Time Wasters / Games Kindle Flipboard - random news Plague Inc (like risk but you are trying to infect/kill world) Dead Trigger (FPS to shoot zombies) Andoku 2 (soduku app) Pandora stream generic music
