GWYN going bye bye

EFFECTIVE TODAY:

So web service for this DCLUG website maybe going too, I don't know. Sorry, if you can't see this, maybe that is what happened to this site, I've been editing for over 10 years...

We haven't been meeting in a while, but doesn't mean we can't, just probably only a notice on the mailing list, (presumably someone ports that), not sure... Bug your local admins, officers, not the WebNewbie, as IDK...

20130505 Webnewbie

Response on the list was that only mail was moving, so stay tuned for more info, at a later date...


February 2013 Announcement

From WebNewbie to the list:
Is there enough interest in meeting today?

Why?

because we haven't in a while, AFAICT

When?

tonight, third Wednesday 7 pm as usual

Where?

are we set with a place?
worst case, go to RFA outside the door and then we wander to some other place for food

What?

Organizing, updating, social, latest greatest toys, etc webnewbie,
if there is enough interest/ response, I'll put it up on the website for those lucky few who read it online instead of on list...


October 2012 Announcement

On Wednesday October 17, 7.00 pm or thereabouts, Charles R. Kiss, newly elected to the Tux.org Board of Directors, will briefly discuss the improvements planned to the servers and other recent actions of the board, followed by a brief question and answer time and likely some other social and technical time...


September 2012 Non Announcement

WebNewbie, never one for much formality, did a little impromptu, unannounced except for on the list, Show and Tell of some gadgets, including RaspberryPi.org, tried HDMI to the host's flat screen and assorted other topics interspersed. There was also some discussion of LAMP (Linux Apache MySQL Perl/PHP stack) and we went home.


August 2012 Non Announcement: Cancelled

Wednesday August 15, 2012 7 pm

No speaker plus criticisms of this website = no meeting, as webnewbie isn't investing time to make/gen a meeting, given recent threads like Web Presentation by people who don't even show up. Snarky, but true.


July 2012 Announcement: LLVM Program Verification Tools, and/or Social

Matt posted an idea to the list:

I don't know if a topic has been chosen yet but I think A discussion on LLVM (llvm.org) would be cool. In particular, the program verification tools like clang static analyzer, KLEE, and SAFEcode. Symbolic execution is fascinating to me, but I don't have any experience using it.

So we will try meeting and discussing what we know about it, what questions we have, and there is an online demo version if some people have some code to try too...

All else fails, we do a social for the remaining meeting time.


June 2012 Announcement: Tux.org Elections and Social

Wednesday June 20, 2012 7 pm

Tux.org Board elections (see slate on emails) and whatver social and/or technical forms, in record "feels like" 109 F heat. Others have proposed meeting the following week, and doing things electronically. Check the list(s) for more info. WebNewbie


May 2012 Announcement: UEFI Video

3rd Wednesday 7pm as Usual

From Przemek to the list:

I hear that there's a core group of DCLUG members that met a couple of times and had a good time, which is great. I am planning to come down, and if people are interested we can show a video presentation by Matthew Garrett about the new firmware, UEFI. Basically, the old PC BIOS is running out of steam even on Intel PC/x86 platform, and it doesn't exist on Apples and the newly important ARM platform. UEFI was proposed as an improvement and as you may expect it has both advantages and flaws. Matthew is working on integrating UEFI platform into Fedora/Redhat/Linux boot and install processes.

April 2012 Pseudo Announcement: Social

A few people have expressed interest in meeting this month, Przemek is unavailable, so on Wednesday April 18th at 7.00 pm, bring something to talk about, and some money to go eat somewheres locally, in case no one has anything [formal] to present... Meet outside our regular space, if no regular attendees show up to let you in, leave a sign on the door in case others are late and proceed to stated local eatery... Sincerely, WebNewbie


March 2012 Non Announcement

From Przemek to the DCLUG email list:

Rain + no speaker = no meeting---sorry for the late communication.

I went to a DevOps sysadmin group meeting yesterday; they discussed system configuration tools: cfengine, chef, puppet and juju). Is there someone that could do a talk about some of those?


February 2012 Meeting Announcement

The February 2012 meeting of Washington DC Linux user group will take place on Wednesday, February 15 at 7pm.

Statistical calculations are hard: if the concepts weren't hard enough to understand, the amount of data is mind-crushing. Manipulating and displaying such data is a tough job, addressed by computer programs ranging from simplistic tools like Excel, to specialized systems such as SPSS, S and R.

Abhijit Dasgupta will present R, a Free Software reimplementation of the S statistical computing system written by Chambers et al. at Bell Labs. S and R are generally considered to be state of the art tools to read, process and present statistical information.

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).


January 2012 Meeting Cancelled

Przemek to the list:

The February 15 DCLUG meeting is already scheduled but we don't have anything on the agenda today, so I suggest cancelling.


December 2011 Meeting Announcement

The December 2011 meeting of Washington DC Linux user group will take place on Wednesday, December 21 at 7pm.

The WikiMedia Foundation offers Wikipedia's in nearly 300 languages. For those people who want a personal copy on their own PC, there is a new software, WP-MIRROR, which will be released under GPLv3 at the end of this month.

WP-MIRROR is a mirror-building utility for Wikipedia. The user specifies a list of wikipedia languages to be mirrored (e.g. 'en' for English, 'ja' for Japanese, etc.), and the software automates the entire process.

The author, Dr. Kent L. Miller, will describe the process of building mirrors, including: hardware issues, database optimization, MediaWiki configuration, image processing, virtual host configuration, and so on.

Slides:
wp-mirror_v0.2.pdf

RELEASED:

Dr. Kent Miller released WP-MIRROR 0.2 during the holiday. Please take a look at http://www.nongnu.org/wp-mirror/. Feedback is welcome.


November 2011 Meeting Non Announcement

From Przemek to the list:

Given the weather and the fact that we don't have a talk let's cancel the meeting this month and plan for Dec 21.


October 2011 Meeting Announcement

The October 2011 meeting of Washington DC Linux user group will take place on Wednesday, October 19 at 7pm.

The topic is virtualization: where it came from, what it's good for, how it works on a modern Linux system. We'll discuss QEMU, Xen, KVM, libvirt, virt-manager, and advanced concepts, such as enterprise virtualization, migration, I/O, etc.

Slides:
VirtualizationLinux.pdf


September 2011 Meeting Announcement

The September 2011 meeting of Washington DC Linux user group will take place on Wednesday, September 21 at 7pm.

Donald Wales, Vyatta Director of Sales, Jay Lee, Vyatta Product Manager and Sid Wilroy of REI Systems will make the presentation covering aspects of the following topics:


August Meeting Announcement

The August 2011 meeting of Washington DC Linux user group will take place on Wednesday, August 17 at 7pm.

Przemek Klosowski will talk about setting up an enterprise class storage server on residential class budget. It turns out that it is surprisingly hard, which is probably why the big guys can charge the prices that they do. Przemek will talk about putting large numbers of disk in limited space,connecting them to the computer and to the network, and setting up a SAN or NAS server.

Slides:

DC LUG meeting July 20, 2011: Open Source medical data system mHealth based on Drupal

The July 2011 meeting of Washington DC Linux user group will take place on Wednesday, July 20 at 7pm.

Sanjay Patel and Adam Hammouda of WebFirst will talk about mHealth, the mobile medical data collection program they are working on. The health care IT is a good area for Free and Open Source Software because of the open and rapid development style, flexibility, and scalability of the FOSS development process. This translates into better decision support and improved quality of personal health care for all of us.

Sanjay and Adam will show how they designed mHealth on the Drupal platform, giving them readily available modules, and easy extensions at relatively low cost. Some of these functions include: data quality review, workflow, data visualization, GIS and social media sharing, and ability to collect data from and publish to a variety of platforms (web, Droid, iOS,SMS).


Check DCLUG email list for updates

As the webnewbie has gotten extremely lazy,

and until we meet regularly,

that is the best information available anyways...

(FWIW: Last WebNewbie saw the GlusterFS presentation was off for June,

but some mention if people wanted to meet anyways...)


April Announcement: NO MEETING

No speaker, so I suggest we cancel the meeting today.

I have a possible speaker for June 15:

GlusterFS is at the core of s scale-out storage solutions. GlusterFS is an open source, distributed file system capable of scaling to several petabytes and handling thousands of clients. GlusterFS clusters together storage building blocks over Infiniband RDMA or TCP/IP interconnect, aggregating disk and memory resources and managing data in a single global namespace. GlusterFS is based on a stackable user space design and can deliver exceptional performance for diverse workloads. GlusterFS supports standard clients running standard applications over any standard IP network.

The speaker is from out of town, so I want to find out how many of you are interested and would plan to attend, given that we haven't been meeting for a while. If I get at least 10 people, I will ask them to come.

Greetings

przemek


March 2011 Announcement: Cancelled

from Przemek to list: I just got a word that our speaker will not be able to make the meeting, so there will be no DCLUG talk tonight.


February 2011 Announcement: Organizing?

From Przemek's email to the list about the meeting(s):

It turns out that Jared can't make it in February; we're talking about rescheduling for either March or April. I won't be able to make it downtown this Wednesday---if people feel like meeting, please coordinate on the mailing list.

On a further note, it's clear that we're hitting doldrums with the meetings. While I have some ideas for the talks both from external speakers and prepare some by myself, I invite people with more time and initiative to step up as co-organizers or even to take over the scheduling. As it is now, we've lost momentum---if people are OK with having less regular meetings than we can leave it as is, but if someone feels the mojo to drive a faster pace, please pipe in.


January 2011 Non Announcement: No Meeting

Let's cancel the DCLUG meeting tonight. Stay tuned for next month: I have a shot at a visit from Fedora director Jared Smith and if it's not that, there's the next instalment of the virtualization series.

December 2010 Announcement: No Meeting

Email to the list from Przemek:

Given that we have no talk, it's cold and everyone is busy before the holidays, let's cancel tonight's DCLUG meeting. See you in January!


November 2010 Meeting Announcement

The November 2010 meeting of Washington DC Linux user group will take place on Wednesday, November 17 at 7pm.

John Holland will talk about RedHat virtualization setup (RHEV), and how it works with Satellite and custom RPMs for updates

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 remaining meeting date for 2010 is Dec 15.


October 2010 Meeting Announcement

The October 2010 meeting of Washington DC Linux user group will take place on Wednesday, October 20 at 7pm.

Rob Pegoraro, the Technology columnist at Washington Post, wrote about Free and Open Source projects in the past, and has some interesting insights on the way FOSS technology is presented to the public. We know that FOSS is excellent and solves practical problems while being arguably more secure than the alternatives---so why does it get no respect among the public?

Rob is an interesting, outspoken and opinionated fellow, so this is going to be an interesting discussion; please come and join us.

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.

The meeting dates for 2010 are Nov 17, and Dec 15.


September 2010 Meeting Non Announcement

Przemek posted out to the list(s):

John Holland and myself were planning to do a virtualization talk, but we both ended up with a conflict tomorrow. This is probably the Universe's way of suggesting to postpone the meeting.

Next month Rob Pegoraro will stop by and talk about his attempts to advocate FOSS through his Washington Post technology column.

John and I are planning to finally deliver the virtualization presentation in November.


AUGUST 2010 MEETING CANCELLED

Due to lack of participation, heavy rain and whatever...


August 2010 Announcement: Lightning Talks

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...


August 2010 Linux Picnic

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...


July 2010 Non Announcement

From Przemek to the MA-Linux list, dated on or about July 13, 2010:

June 2010 Slides

In record time, Dr. Kent Miller provided slides from last night's talk
ipv6_v0.2.pdf


June 2010 Announcement

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.

  1. demystify the IPv6 transition,
  2. help attendees achieve connectivity, and
  3. recommend steps towards certification.
  1. a Linux 2.6 box to serve as an IPv6 router,
  2. an 8-port, level 2, unmanaged switch, and
  3. a small number of CAT5 Ethernet cables.
  1. your laptop running Linux 2.6,
  2. a CAT5 Ethernet cable, or
  3. (optionally) a wireless access point.


May 2010 Slides

Slides from the NoVALUG talk are up on:
http://drwho.virtadpt.net/archive/2010/04/10/my-novalug-presentation-was-a-success

DCLUG specific slides (very slight variations noted from presenter and author) to be posted when available.


May 2010 Announcement

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.


April 2010 Announcement

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.


March 2010 Announcement

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.

December 2009 Announcement

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.)

December 2009 Slides:

None Yet...


November 2009 Announcement

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:

  • unscrambling-regular-expressions.pdf
  • unscrambling-regular-expressions.odp

  • October 2009 Announcement

    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.


    September 2009 Announcement

    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.


    August 2009 Slides

    Przemek has graciously offered the slides, and they are put up here:

  • BTRFS-DCLUG.odp
  • BTRFS-DCLUG.pdf
  • BTRFS-DCLUG.ppt
  • 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... ;-/

    August 2009 Announcement

    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.


    July 2009 Slides

    Mackenzie's slides for July talk:

  • wifi_security-lug.odp
  • wifi_security-lug.pdf
  • wifi_security-lug.ppt

  • July 2009 Announcement

    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.


    June 2009 Announcement

    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.


    June 2009 PreRelease: Blender

    Blender is probably the topic, so start studying up now... More official stuff likely to follow, as developed, approved, etc...


    May 2009 Announcement

    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?


    April 2009 Announcement

    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:

    March 2009 Non-Announcement

    Shortly after 2 pm today:
    [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.

    Meeting Details

    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.
