Due to lack of participation, heavy rain and whatever...
Meeting Wednesday August 18, 2010, 7-9+ pm.
Given that preparing a full meeting talk can be a fair amount of work (and it's still summer time, as the heat reminds us...), shorter talks, called Lightning Talks, usually limited to 5 minutes or so, provide an easier way to get started presenting, so if you've got a topic you'd like a technical Linux and related Open Source audience to hear, send it to the DCLUG mailing list, and please RSVP, as a way of gauging interest in this month's meeting...
Webnewbie note: NoVALUG/Tux.org people are organizing a Linux Picnic currently in the Arlington area for after the NoVALUG monthly meeting time frame (second Saturday). Sorry for the cross posting to DCLUG, but it's closer than previous years, and generally been fun... See the Novalug list for more info...
From Przemek to the MA-Linux list, dated on or about July 13, 2010:
DCLUG July meeting falls on July 21. I will be at OSCON, and we don't have a speaker aligned. If someone can come up with a topic or people want to meet and chat, please speak up. Otherwise, let's give ourselves a summer break.
On another note, the USENIX Security Symposium is next month in D.C. Here's a blurb I am forwarding on behalf of the organizers:

In record time, Dr. Kent Miller provided slides
from last night's talk
ipv6_v0.2.pdf
The June 2010 meeting of Washington DC Linux user group will take place on Wednesday, June 16 at 7pm.
Originally, ARPANET ran the Network Control Program (NCP). The NCP had many limitation (including address space) and was in time superseded by TCP/IP. However, users were reluctant to make the transition. So, in 1982, Vinton Cerf and Jon Postel brutally forced users to switch from NCP to IPv4 by instructing the Internet gateways to block all NCP traffic.
Now, almost 30 years later, it is the IPv4 address space that is approaching exhaustion. If current IPv4 address allocation policy continues, then IANA will allocate its last remaining /8 block in 2011-06, and the RIRs will allocate the last of their IPv4 addresses in 2012-04. Yet the demand for addresses will only grow due to the rapid proliferation of hand-held devices and the ongoing roll-out of Internet services in the third-world.
IPv6 is a complete rewrite that offers a vast address space, new services, and solutions to old problems. Yet, as with the change from NCP to TCP/IP, adoption has been slow due to inadequate transition planning and lack of pressure to change---until recently. While it is unlikely that someone like a Cerf or Postel will pull the plug, the ongoing demand for addresses means increasing pressure to change.
DCLUG members and members of the general public are encouraged to attend the IPv6 Install-Fest organized by Kent Miller.
The meeting location is our usual 2025 M street, NW in downtown DC. There will be signs in front of the building. The location is within 3 nearby Metro stops, both on the red (Dupont, Farragut North) and blue/orange (Farragut West, Foggy Bottom [a bit of a hike]) lines.
Parking in the area is available for approximately $5; there's even parking in the building itself. Street parking requires feeding the meters until late in the evening. There's a parking lot at 23rd St. between M and L that is not enforced after 7pm (people have successfully parked there for years---no one we know was ticketed or towed yet, but it could happen).
The meeting dates for 2010 are Jul 21, Aug 18, Sep 15, Oct 20, Nov 17, and Dec 15.
Slides from the NoVALUG talk are up on:

DCLUG specific slides (very slight variations noted from presenter and author) to be posted when available.
The May 2010 meeting of Washington DC Linux user group will take place on Wednesday, May 19 at 7pm.
The twenty-first century has brought with it a disturbing loss of personal privacy. Communications are routinely monitored for content and traffic analysis can be used to determine which IP addresses are exchanging meaningful amounts of traffic. Onion routing is a technique by which a subset of all network nodes are tasked with relaying encrypted traffic for clients. Tor is an implementation of an onion routing protocol which defends against traffic analysis attacks; it also implements hidden services only reachable from within the Tor darknet. Tor is endorsed by a number of human rights and advocacy organizations, including as the Electronic Frontier Foundation, Reporters Without Borders, and Wikileaks.org. Tor is also used by the US Department of Defense and the US Military.
The presentation will describe the origins of Tor as well as how the darknet functions. The threat model Tor was designed under will be discussed, and a demonstration will be given of how to set up the client, middleman and exit nodes. A demonstration of how to set up a web server as a hidden service will also be given. Operational security for clients as well as routing nodes will be detailed.
The meeting dates for 2010 are Jun 16, Jul 21, Aug 18, Sep 15, Oct 20, Nov 17, and Dec 15.
The April 2010 meeting of Washington DC Linux user group will take place on Wednesday, April 21 at 7pm.
Our April topic is 'Building software packages, RPM edition'. Software packaging systems are one of the leading features of Linux, benefitting both system administrators and end users. They make it easy to find, load and upgrade software and keep your system well organized.
RPM started life as RedHat Package Manager, but it was adopted by other distributions like Suse, Mandrake, Fedora etc. Package building is a mandatory skill if you want to participate in developing a Linux distribution. This month's talk by Przemek Klosowski will discuss the benefits of packages and show how to make your own.
The March 2010 meeting of Washington DC Linux user group will take place on Wednesday, March 17 at 7pm.
Eric Rzewnicki will talk about Conference Video. Video recordings and live internet streams of a growing number of Linux and Free Software conferences around the world are being produced by teams of volunteers using largely donated resources and Free Software running on Linux. This talk discusses the hardware and software used for a variety of the productions in which Eric has participated. The software covered includes dvswitch and tools from xiph.org. Challenges and experiences with regard to quality sound, lighting, volunteer organization and workflow management will also be touched upon.

The December 2009 meeting of Washington DC Linux user group will take place on Wednesday, December 16 at 7pm.
The computerization of the health care industry is an important area that has been in the news recently, and Free and Open Source software is bound to play a major role. Our speaker this month, Nancy Anthracite, has an unique perspective in this area, so this should be an interesting presentation.
Nancy is President & Chief Medical Officer of WorldVistA, a charitable, volunteer operated nonprofit organization that distributes the open source software, WorldVistA EHR, a medical records and hospital management system developed by the Department of Veterans Affairs that is Open Source. She will give us an introduction to it and also try to give us a rapid fire overview of what is going on in the world of electronic medical records now that there are strong incentives to adopt electronic medical records, a strong push to make them interoperable and huge amounts of money being distributed to implement them through the ARRA (American Recovery and Reinvestment Act.)

The November 2009 meeting of Washington DC Linux user group will take place on Wednesday, November 18 at 7pm.
Zachariah Wadler will be de-mystifying regular expressions. They are great for processing textual input but very intimidating to the uninitiated. He will go over the basic regexp: metacharacters, grouping, etc. He'll show a number of real world examples and the Perl 5 extended regular expression syntax as well.
Slides:
The October 2009 meeting of Washington DC Linux user group will take place on Wednesday, October 21 at 7pm.
Przemek Klosowski will talk about LVM facilities in Linux, in the context of local Logical Volumes as well as iSCSI SAN technology. These things make Linux an enterprise class storage, with high-end features such as fancy RAID configurations, multi-path disk access, live data migration and size expansion/shrinking, etc.
DCLUG meeting date is tonight. I hope the DCLUG mailing list is up after the recent debacle. I don't have any presentation scheduled, so we will just meet and chat. See you at 7pm.
Przemek has graciously offered the slides, and they are put up here:
Enjoy, and hopefully (Webnewbie suggests) we make it a policy to require giving the slides in order to present, as my little fingers could not keep up with trying to type it all in... ;-/
The August 2009 meeting of Washington DC Linux user group will take place on Wednesday, August 19 at 7pm.
Przemek Klosowski will talk about B-Tree File System, (BTRFS, pronounced ButterEffEss), the new-and-upcoming Linux filesystem that may replace the EXT family as the default storage for Linux. BTRFS was conceived by Chris Mason to compete with ZFS, and to address problems with the current generation of file systems. We'll will discuss and compare features, discuss history and future developments of BTRFS.
Mackenzie's slides for July talk:
The July 2009 meeting of Washington DC Linux user group will take place on Wednesday, July 15 at 7pm.
Mackenzie Morgan will talk on how to lockdown a Linux laptop if you're somewhere you don't trust the WiFi (like a hacker con) while still getting online.
The June 2009 meeting of Washington DC Linux user group will take place on Wednesday, June 17 at 7pm.
Jason van Gumster will talk about Blender (www.blender.org), the free 3D modeling and animation suite. He'll cover some of Blender's history and guide the uninitiated past the intimidating and quirky Blender user interface. If you were ever impressed by 3D computer-rendered artwork and wanted to try your hand at it, Jason will help you get over that initial hurdle and wrap your brains around Blender.
Blender is probably the topic, so start studying up now... More official stuff likely to follow, as developed, approved, etc...
The May 2009 meeting of Washington DC Linux user group will take place on Wednesday, May 20 at 7pm.
Greg Dekoenigsberg from RedHat will talk about role of Free and Open Source Software in Open Government.
The open government movement is quickly gaining strength. It's in everyone's best interest to ensure the transparency and freedom of the technical infrastructure that runs our federal, state and local governments.
Open source developers are uniquely qualified to lead this effort. How can open source developers participate in this movement today? What are the challenges that we must overcome to bring more open source developers to the open government movement?
The April 2009 meeting of Washington DC Linux user group will take place on Wednesday, April 15 at 7pm.
Peter Haggerty from Librato will give away five 1GB flash drives and present clever user space techniques for process management. The Librato tools provide various process management capabilities -- from monitoring both actual and desired resource usage inside of a process to checkpointing processes on one machine and resuming them on a different machine. None of these techniques require anything more than setting a few environment variables to preload a shared library. No recompiling, no relinking or no kernel mods.
Peter will discuss in detail a load management technology which guarantees different resources levels to competing groups of processes on the same operating system instance. Common examples of using this technology include:
1. dueling oracle databases where one instance gets 20% and the other 80% of the CPU allocations
2. fencing in aggressive or poorly behaved grid workloads to prevent collateral damage
[Dclug] DCLUG meeting bust from: Przemek Klosowski to: dclug email list date: 1:39 PM (2 hours ago) Let's cancel the DCLUG meeting for tonight-I don't have a talk, so it would be a social occasion anyway, and people are tired after FOSE. Everyone is welcome to come down to the meeting place and go for some food, of course, but there will be no formal meeting. _______________________________________________ Dclug mailing list Dclug@calypso.tux.org http://calypso.tux.org/cgi-bin/mailman/listinfo/dclug
HacDC (last month's presenters) has an electronics class tonight, according to their blabber list and calendar...

The February 2009 meeting of Washington DC Linux user group will take place on Wednesday, February 18 at 7pm.
The first presentation will be about 20-30 minutes and it will cover HacDC. Here's a blurb on that.
HacDC is DC's premiere hackerspace, bringing together a wide variety of people with an even larger variety of interests together under one roof. In this presentation, Serge Wroclawski will discuss the organization, what it's up to and where it's going.
The second presentation will be the remainder of the time and will discuss Arduino. Here's a nice blurb for that.
The Arduino has made microcontrollers simple and accessible. In this presentation, Serge Wroclawski will explore the Arduino hardware and software environments. Following this talk will be several small hardware demonistrations using the Arduino by either thier creators or other Arduino enthusiasts.
His main topic will be the Arduino microcontroller, a simple and accessible hardware and software platform for embedded computing. Serge and his HacDC colleagues will show several Arduino-based projects.
The January 2009 meeting of Washington DC Linux user group will take place on Wednesday, January 21 at 7pm.
Joe Klein will talk about using, hacking and securing IPv6, the upcoming new version of the IP protocol. He will cover the basics and rationale for IPv6, and the implementation issues. Because of significant design changes, IPv6 introduces its own set of security issues: Joe will discuss pitfalls to avoid, and how to leverage new IPv6 features for a better, more secure networking.
The meeting location is our usual 2025 M street, NW in downtown DC. There will be signs in front of the building. The location is within 3 nearby Metro stops, both on the red (Dupont, Farragut North) and blue/orange (Farragut West, Foggy Bottom [a bit of a hike]) lines.
Parking in the area is available for approximately $5; there's even parking in the building itself. Street parking is free after 6:30pm, but scarce. There's a parking lot at 23rd St. between M and L that is not enforced after 7pm (people have successfully parked there for years---no one we know was ticketed or towed yet, but it could happen).
Detailed directions can be found at meetings.
