second and fourth Friday
second and fourth Friday
We cover the north-east San Francisco Bay Area — Concord, Pleasant Hill, Martinez, Danville, Lamorinda (Lafayette, Moraga and Orinda), Walnut Creek, and nearby areas in Contra Costa County — aiming to advocate and spread open source software, do LUG events in the Diablo Valley area. We respect and use other operating systems. We are mindful of and respect the effects of networks, Moore's Law and project management constraints in tech projects.
A new type of thinking is essential if
mankind is to survive and
move toward higher levels.
Albert Einstein, 1946
Our purpose is to support people who use and develop open source software. This includes welcoming people with less experience trusting open source and assisting people in releasing their software.
New to Linux? Start by reading this one page PDF tri-fold. For some highlights, check out why Linux is better.net. If you have never downloaded "Linux" before and would like to try booting your computer with Linux, just ask. We usually have available CDs (DIY or pressed) and versions of Linux we can copy to your USB flash drive at no charge. Some of us regularly donate time and materials to provide Linux to newcomers. You can even try Ubuntu without booting or installing it through a simulation. Edubuntu allows a web based OS & software trial called weblive.
Why? Freedom is important. Creative Commons content and Ubuntu software are part of a set of movements called the open movement. Our society is evolving and digital citizenship is less optional today than it used to be. The four freedoms of Richard Stallman and the 10 criteria of the open source definition are the basis of this type of software licensing.
WC Time: second and fourth Friday at 7:00 PM. Meetings are informal and generally last from one to three hours, depending on attendance. It's perfectly fine if you can't stay the whole time. Drop in visitors are encouraged.
WC Location: Caffe La Scala (Yelp link, Google Map) at 1655 N Main St (at Civic Drive), Walnut Creek, CA. It is primarily a coffee shop in downtown Walnut Creek. Free wifi. Good food (soup, pizza, sandwiches; vegetarian options) and drinks are available in a relaxing environment.
Parking & BART: Free parking is available at metered spaces after 6 PM. It can be tough to find a parking space close by so try to come a few minutes early. The closest paid lot is a block away at the Center for the Arts. Ask us for parking hints at a meeting. Walnut Creek BART is a few blocks away. Walking from BART takes about 10 minutes. There is also a "free ride" - the Route #4 Broadway Plaza bus/trolley that runs every 15 minutes. Look for the green "Free Ride" trolley. Get off the trolley when it turns right in front of the Center for the Arts, Civic @ Locust. Main St. is one block away.
Time: second and fourth Friday at 4:00 PM. Meetings are informal. Drop in visitors are encouraged.
Location: Steeltown Coffee & Tea (Yelp link, Google Map) at 695 Railroad Ave (at E 7th), Pittsburg, CA. It is coffee shop and Mechanics bank. Free wifi. Pastries and drinks are available in a relaxing environment.
Parking: Free parking is available in front of and behind the building.
Different versions of Windows are operating systems (OS). Versions of Mac OSX are operating systems. Linux was created in 1991 by Linus Torvalds in Helsinki Finland, and is now developed by thousands of individuals and corporations around the world whose efforts benefit the entire community. Linux distributions are already the dominant operating systems on web servers and supercomputers by large margins. Every Android phone is a quite powerful little Linux computer. Android phones collectively outsell all other phone operating systems. If you Google or use the Internet you already use Linux. With very few exceptions, every desktop at Google uses goobuntu. Like Mac OSX, Linux is a flavor of Unix which was invented more than 40 years ago by AT&T and evolved with the help of MIT, UC Berkeley and many different companies for scientific and professional supercomputer users who wanted a very powerful and flexible OS. Linux and the software programs that run on it have evolved a lot from their more technical roots and are now very easy to use. One exception to this might be dealing with system time in various representations. Freedom to do what you want with your computer, including understanding and modifying all of the software parts has been important for decades. There are some parallels with the Occupy demonstrations.
Bay Area Groups
Our group member's experiences include offering applications on the Google Play Store, running a Linux From Scratch, loading Puppy Linux on older hardware from RAM, installing OpenWRT on Linksys WRT54GL AP/routers, representing Bay Area user groups at the San Mateo Maker Faire, giving out CDs at Berkeley Solano Stroll and co-hosting an annual olpcsf.org/summit each October in SF.
Members are also active in other groups such as Ubuntu-US-CA, Fedora Project Ambassadors, Partimus, OLPC San Francisco, GidgetKitchen, CABAL, BayLISA, Bay Area Debian, LinuxPicnic, GeekNic, BerkeleyLUG, BUUG, BALUG, SF-LUG, Noisebridge, NBLUG, PenLUG, SVLUG, Felton LUG, LUGOD, SacLUG, BayPiggies, OpenCanopi.com and Dreamfish. Additional lists of regional and state groups include Bay Area Linux Events and CA state groups. Some of us have experience on other flavors of Unix too like Solaris, HP/UX and AIX.
Special mention should be given to our friends at ZaReason in Berkeley for selling Linux preinstalled on desktops and laptops. They are also community supporters in several of the above groups.
Who uses Linux? Linux is most common on servers but is increasingly popular on personal computers. UNIX was originally developed by AT&T, MIT & UC Berkeley in the late 60's and early 70's. The different versions together are sometimes called Unix-Like or *nix. 50 places Google, Facebook, Twitter, eBay, the US (DOD, FAA, Federal Courts, USPS, Navy Submarine Fleet) & other governments, IBM, Amazon, Wikipedia, 75% of stock exchanges (NYSE, London), Internet Archive, CERN, Cisco, Virgin America, Panasonic, Novell. Description of adoption, list of adopters.
A fascinating podcast interviews David Wheeler, a US Department of Defence contractor. His published papers include Why Open Source Software (OSS)?, OSS in US Government Acquisitions & OSS is Commercial Software.
What types of Linux are available? Well, to people that really care about the most subtle of differences, when newcomers say Linux it is usually assumed that most people approximately intend Unix like GNU/Linux Distribution. There are many different distributions available (good lists are on distrowatch & wikipedia or wiki comparison) however some of the UNIX like systems we have discussed at dvlug.org include:
- Debian family with SPI-Inc ( Ubuntu is highly recommended for beginners, Kubuntu, Xubuntu, Edubuntu, Lubuntu, Mythbuntu, Ubuntu Studio, Mint, Backtrack, Crunchbang, Qimo, gNewSense assisted by the FSF/GNU project but currently "dormant", Freespire, Xandros (previously Corel, Xandros purchased Linspire/LindowsOS) )
- Red Hat family lead by Red Hat, Inc. from North Carolina ( Red Hat Enterprise Linux (RHEL), CentOS, Fedora, Scientific Linux, Mandriva (formerly Mandrake of Paris, France and Conectiva of Curitiba, Brazil) )
- Slackware family ( openSUSE, SUSE formerly a German company based in Nuremberg, then owned by Novell and now owned by Attachmate Group of Houston, TX )
- source based (Arch, Gentoo )
- BSD family (Darwin is the basis of Mac OSX. Free BSD traces its roots back to the original Berkeley Standard Distribution or "west coast" UNIX.)
- Some diagrams help illustrate the relationships between the major Unix-like systems and Linux distributions. All "unix-like" systems evolved in some way from the 1969 AT&T efforts and are a blend of BSD (west coast) UNIX and System V (MIT, east coast) UNIX. The GNU system was announced in 1983 by Richard Stallman while working at MIT but (still) lacks a stable kernel. These GNU tools enabled the development of the Linux kernel announced in 1991 by Linus Torvalds while a student at the University of Helsinki. Linus is now a Fellow with the Linux Foundation in Portland, OR.
When did Linux celebrate its 20th birthday? 2011!
We announce our weekly Friday meetings on the email list and sometimes host discussions. We sometimes send news and event notices of Linux- and LUG-related topics. To post a message to all the list members, send email to email@example.com. For more information, archives, and to subscribe, visit the list info page. Our list is generously hosted by Rick Moen.
