IO launches an OpenStack cloud running on open source servers

February 1, 2014

~~~Awesome. •••Felicia


Modular data center expert IO is getting into the cloud provider business, launching a new service called IO.Cloud that’s built using Open Compute server designs and runs the OpenStack cloud computing operating system.

That’s a lot of open source, but the company seems to think it’s necessary. According to the IO.Cloud website: “IO.Cloud is built on Open Compute because it provides our engineers with the flexibility to configure and optimize the hardware specifically for scale cloud deployments … IO.Cloud uses OpenStack Cloud components that are interoperable and designed to support standardized hardware implementations.”

IO is pitching IO.Cloud as an enterprise cloud offering, and if it plans to legitimately compete against larger cloud providers for those workloads, the company and its cloud can use any advantages they can get. IO.Cloud is available in hosted and on-premises versions, and the Open Compute hardware almost certainly will let IO operate its public cloud infrastructure more efficiently, as well…

Ear Candy Tools for HeadFets

January 22, 2013

Women Headphones
Audacity-LogoYesterday the Audacity® team released a new version of the free, open source, cross-platform software for recording and editing sounds. Nice! Version 2.0.3 is now available for Windows®, Mac®, GNU/Linux® and other operating systems. If you are so inclined, you can also opt to build Audacity yourself, by downloading the source code.
This software is for all those people with a headphone fetish!!

Changes between 2.0.2 and 2.0.3


  • Crash using Undo whilst time-shifting a track.
  • Crash using Repair if the selection extended into an empty track.
  • Export Multiple didn’t prevent export if there was no audio or all audio was muted. This allowed export of small invalid files.

Time Track

  • Loop Play of a speeded-up track inserted silence.
  • Playback and rendering was significantly inaccurate, creating audible and visual glitches.


  • The mnemonics character “&” was read out by screen readers in most of the Preferences choices.
  • NVDA did not read static text in most dialogs. Text can now be read by using INSERT + B.
  • JAWS and Window-eyes misread the “Duration” control in Silence Generator.
  • Toolbar buttons could not be pressed by ENTER
  • Other interface bug fixes.


  • The SoX Resampler library (libsoxr) has replaced libresample in Audacity releases, offering both higher quality and greater speed. .

Time Tracks new features

  • “Set Range” now changes only the range of the Time Track, preserving the pitch/speed set by any existing warp points.
  • Vertical scale added with options for linear and logarithmic display and interpolation.
  • Upper and lower speed limits will now be remembered when saving and reopening a project in 2.0.3. Warp points in projects saved by previous Audacity versions will be correctly restored in 2.0.3.
  • Warp points saved in a 2.0.3 project will be preserved if opened in previous versions but playback and display will be incorrect.

New effects

  • Studio Fade Out (uses a filtered “S” curve).
  • Adjustable Fade (accessible effect for creating partial fades and adjustable fade shapes).
  • Bass and Treble (replaces Bass Boost).


  • Real sample rates up to 384000 Hz are now supported for playback and recording in high resolution devices (the maximum is up to 192000 Hz for Windows DirectSound host).
  • Labeled Regions in Edit Menu is renamed to “Labeled Audio” and now allows splits to be placed at point labels. Labeled audio regions that touch without overlapping are treated as separate regions. Overlapping labeled audio regions are treated as a single region.
  • New Croatian translation of Audacity.


  • CMake is required in order to build libsoxr.

Drafting “Midnight”

October 10, 2012

Mar~ I love, love, love you gurl! Today you gave me just what I was looking for. After we talked about memorable movie quotes and I looked at the list you sent me, my ideas started flowing like lava. I ended up going with the Dracula sound clips. Nice!! I am saving the best one (about the ocean) for a slow mix set. Why didn’t I think of that movie?! You lil vamp you! Tonight I drafted “Midnight” using Audacity. So far the mix features two Dracula clips, a Patsy Cline song, a Pitbull song, a Miguel Jontel song, and sounds of a heartbeat. I can always count on you Mar. You are awesome. Thanks!! 🙂 I can’t wait to finish.

Dream Job: Implementing Open Source Preservation Solutions for Digital Collections

September 27, 2012

This totally rocks! Today the University of Illinois at Urbana-Champaign published a news release courtsey of Dell titled “New Preservation Archive.” The release says “working with Dell, the University of Illinois at Urbana-Champaign has created a new digital archive for its university system that simplifies how it manages digital assets, including rare books and faculty intellectual property output such as research documents, papers and lectures — content typically produced in multiple digital formats. The new archive reduces storage costs and streamlines the management, retention and protection of scholarly works through a solution based on the Dell DX Object Storage Platform and DuraSpace Open Source Fedora Commons Repository Software. Critical for the university was the ability to meet today’s needs and to scale efficiently over time as digital content evolves and grows.” This is awesome! Universities are taking advantage of open solutions, but they have people who know how to build and manage the systems. DuraSpace also rocks! I worked with DSpace when I built small scale, virtual digital repositories from the ground up in my UofA program. I really need to work toward that Doctoral Program. The full news release is below.

Dell and University of Illinois at Urbana-Champaign Create Preservation Archive with Open Source Fedora Repository Software

Date : 9/27/2012~~ Round Rock, Texas

~~~One of the largest public university libraries in the country uses open source software on Dell DX Object Storage Platform to manage and protect digital assets.

~~~University lowers storage total cost of ownership with scalability to support archive growth.

Working with Dell, the University of Illinois at Urbana-Champaign has created a new digital archive for its university system that simplifies how it manages digital assets, including rare books and faculty intellectual property output such as research documents, papers and lectures — content typically produced in multiple digital formats. The new archive reduces storage costs and streamlines the management, retention and protection of scholarly works through a solution based on the Dell DX Object Storage Platform and DuraSpace Open Source Fedora Commons Repository Software. Critical for the university was the ability to meet today’s needs and to scale efficiently over time as digital content evolves and grows.

Explosive data growth and large data sets make it more difficult for libraries, museums and government organizations to efficiently preserve and protect documents, multimedia content and digital assets for future generations. As one of the largest public university libraries in the world, the Library at the University of Illinois at Urbana-Champaign manages the intellectual property and digital content created by faculty, administrators and students — from one-of-a-kind, fragile books that can create 600 to 800 image objects once digitized, to retiring professors’ collections of work over a 20- to 25-year tenure.

After considering its digital archive and retention goals, the University of Illinois customized a version of Fedora Repository Software and combined it with the Dell DX Object Storage Platform. The platform automatically replicates an archive master and a working master of each file to simplify data backup, storing one copy on the University’s main library cluster and a second copy in its engineering library. In the future, a third copy will be archived in the cloud to further simplify data access and sharing across the University system. The Dell DX Platform also produces metadata to manage the archive, identifying files that need to be transitioned from older to newer digital formats for future generations. And the DX Object Storage Platform’s plug and play framework lets archivists add additional retention capacity to the digital archive as it is needed, simply and efficiently.


John Mullen, Vice President, Education and State & Local Government, Dell
“With the transition from stacks and the Dewey Decimal system to bytes, clusters and metadata, academic libraries need a digital archiving strategy that addresses their immediate and future needs. The University of Illinois’ innovative and open approach to this challenge is a practical model for any university.”

Thomas Habing, Research Programmer, Research and Development, University of Illinois at Urbana- Champaign Library
“This opportunity provides us with extra resources to further the development of the Library’s digital preservation archive. It also allows us to continue to utilize Open Source Fedora Commons Repository Software while at the same time employing a commercially-supported object storage platform with many digital preservation features, such as replication and validation, which we will not need to implement ourselves. Plus, we can share all of our development efforts back to the open source community which helps everyone, including Dell.”

Michele Kimpton, CEO of DuraSpace
“The Open Source Fedora repository platform is used by more than 400 institutions around the globe. We believe commercial implementations, such as Dell, provide our users with the best of both worlds — hardware and services from a large-scale commercial vendor integrated with open source software, Fedora Repository. The total package provides users with greater transparency and durability in the long run.”

Press On With Imagination

August 12, 2012

Cali DVD Screen Shot_8.12.2012


“I am enough of an artist to draw freely upon my imagination.
Imagination is more important than knowledge. Knowledge is
limited. Imagination encircles the world.”
~~~Albert Einstein


Man is still the most extraordinary computer of all.”
~~~John F. Kennedy


Well after two days— it is done. Late last night, I finished my Cali DVD project. I have completed a haphazard masterpiece which could have been better! Like a virtual Jacobus de Varagine, I compiled my Golden Legend, a personal collection of California memories. To complete this project, I used: two computers (cross platform); five software programs (2 of them open source); an iPod Touch; and a microphone (digital audio input). These tools were used to sort through, organize, and edit over 200 photographs and several GB of video footage. One of the programs was used to complete the voice overs (audio) that I put into the movie. I selected those things I felt were the best of the best. Hey- it was like the digital Olympics up in this house- haha- only the best made the final cut! The DVD was screened today to a few different family members- and it was fun. I have to say that Daryn and I had a blast recording the voice overs. We laughed and laughed. By all means, the project isn’t perfect, but I wanted to have it ready to show today. My next step will be to track down a video host which will allow me to upload the entire movie (close to 20 minutes) into the cloud. If I am not happy with anything I find, I will break down the movie into four segments and upload it to YouTube. This way- I can share my trip with everyone. I really want my friend Elaine to see it. She lives in Corona (CA) and I saw her on my last day of the trip. Hopefully- I can get that done within the week. I am such a lover of technology. What can I say? I am in awe by the things we can do as humans with our minds. I really think that the two quotes above sum that up. Computers are nothing without the people who create them- the engineer, the coder, the script writer, the mad brainiac. These are the real computers behind the computers right? Each and every one of these masterminds has one thing in common- they understand that they are only limited by the power of their imaginations.

A Lasso and An Electronic Bull: the Media Rodeo

April 23, 2012

Electronic bull digital composite by Felicia Lujan. Image includes a video still from Ciara's Ride video featuring Ludacris, and a photograph of an electronic circuit. The composite was created in Adobe Photoshop using a darkened layer and a layer screen, as well as an artistic fresco filter.

Today I attended a Media Rodeo here in Santa Fe. This was the title of what I am sure the organizer would call an “unmeeting.” The phrase Media Rodeo is rather catchy, and it likely coincides with an attempt to lasso ideas and information. We discussed all things digital, exploring issues, programs, and trend setters. I found the session rather useful. It is always good to meet with other professionals to purge and regurgitate the bits and bytes in the dark recesses of my mind. Hopefully I will remain on the “invite” list, as I feel that I have much to contribute. Following are a few of the programs featured in a demo, and one site that I found particularly useful.



This program features the use of Google Maps. The maps are basically an underlayer for the web site administrator to pin images/photographs on. This is a very cool program. When pinning images to the map, you can be as specific or general as you would like. In other words, you can post images to a specific address on the map, or maybe to a particular town and/or site. The software also provides a section to control copyright over the images posted by the administrator. The copyright information can include the author of the image, a caption, a link to the repository and/or archive, and the contact information for the repository and/or archive. There is also a “street view option,” which allows the end user to have a digital stroll down selected streets on the virtual maps. In History Pin, the administrator can upload videos, text, audio, and timelines for specific sets of images.

From the web site…..

Historypin is a way for millions of people to come together, from across different generations, cultures and places, to share small glimpses of the past and to build up the huge story of human history. Everyone has history to share: whether its sitting in yellowed albums in the attic, collected in piles of crackly tapes, conserved in the 1000s of archives all over the world or passed down in memories and old stories. Each of these pieces of history finds a home on Historypin, where everyone has the chance to see it, add to it, learn from it, debate it and use it to build up a more complete understanding of the world. Historypin has been developed by the not-for-profit company We Are What We Do, in partnership with Google.”

Felicia's Media Rodeo notes with a glowing edge filter in Adobe Photoshop.



We had a look at the dashboard of Tumblr. In Tumblr you can insert text, photos, quotes, link to items, chat, and upload audio and video. The program also offers a “queue” option. The feature is particularly handy for busy people (who isn’t?). This allows the administrator to set automatic posts. The posts can be automated for daily, weekly, or monthly content uploads. It can also be queued for specific dates. The items in the queue can be programmed for a year or more in advance if necessary, and if you are sure which content you would like to go up regularly.

From the web site…..

Tumblr lets you effortlessly share anything. Post text, photos, quotes, links, music, and videos, from your browser, phone, desktop, email, or wherever you happen to be. You can customize everything, from colors, to your theme’s HTML. Collect Every Moment Wherever You Go. Browsing through various tumblelogs is like sifting through the Lost and Found Department of the entire Internet. It’s a beautiful mix of everything and anything, from the shocking to the spectacular.”



For me, Pinterest just seemed like a fun way to show people what you are interested in. I know that recent digital trends have shown that this program is on a steady rise with a huge amount of women. These women are actively contributing to the site by “pinning” and “repinning” content. Some of the stuff from this web site (My Voyage Through Time) has already been picked up by Pinterest users, and some of my digital composites and quotes have been repinned. That’s kinda cool!

From the web site…..

A Virtual Pinboard. Pinterest lets you organize and share all the beautiful things you find on the web. People use pinboards to plan their weddings, decorate their homes, and organize their favorite recipes. Best of all, you can browse pinboards created by other people. Browsing pinboards is a fun way to discover new things and get inspiration from people who share your interests. To get started, request an invite.”

Presentation of Tumblr Dashboard during the Media Rodeo.



We talked a little bit about this web site, which features free manuals available for daily download. There are several kinds of manuals, and it was mentioned that the manual featured today was “Your Guide to Social Media Marketing.” The manuals on this site are said to be well written, free, and useful. I took some time to check out the web site tonight, and it looks like it is sure to be a good tool in the digital arsenal.

From the web site…..

A booming daily blog that features cool websites, computer tips, and downloads that make you more productive. The aim of MakeUseOf is to guide you through the web and tell you about hot websites that you have never heard of, best software programs, and all kinds of “how to” tips for Windows, Mac and Linux computer users.”


Rock on with the Audacity 2.0 Release

March 21, 2012

Two screen shots of my new version of Audacity 2.0. I downloaded the new version last night. There are some additional features and effects in this 2.0 release. Digital composite created by Felicia (I have such a headphone fetish).

I was so excited to get an email this week about a release of the newest version of one of my very favorite programs (of course aside from Adobe Photoshop). Maybe I should say my favorite open source software, which is cross-platform. The Audacity team released version 2.0 (unicode), which I installed and fully loaded last night. Audacity is a free digital audio editing program written by a team of tech/music junkies from around the world. I guess you could say the volunteer developers are the best of the best. The project is hosted by and Google Code, and the program is available for Windows, Mac, and GNU/Linux (and other Unix-like systems). For those of you who care to know, Audacity has been designed based on code from the following projects: expat; FLAC; iAVC; LAME; libmad; libsndfile; Nyquist; Ogg Vorbis; PortAudio; portsmf; Resample; sbsms; SoundTouch; TwoLAME; Vamp; and wxWidgets.

I have given the new version a couple spins, and it seems good to go!! I fully loaded up this time, and included extras that I was missing on the last version because I didn’t install them correctly… 😦 This time, I made sure to install the additional plug-ins I wanted- including: LADSPA, with close to 100 plug-ins; additional effects and filters; and the LAME MP3 encoder, to export MP3 files. Before upgrading to 2.0, I had to use other programs to get the audio files into the formats I needed. The new version also features an FFmpeg import/export library, which allows the import and export of additional audio formats (AC3, AMR(NB), M4A and WMA). With this option, you can also import audio directly from video files. I can’t wait to mess with that to see how it all works! Looks like a headphones weekend! Now- I’m set…
