Welcome to the Disruptive Library Technology Jester. From here you can browse the musings and visions of a library technologist as he walks the fine line between the best of the library profession on one side and the best of technology on the other.

You can navigate through DLTJ several ways. Your first stop might be the introductory material about this blog and the jester himself under the "about" heading to the left. Another way would be to pick a facet below to browse: "by cagetory" for a rough categorization of postings, "by tags" for a finer granularity of topics, or "by date" for a chronological view. Third, use the search box in the left column as a keyword approach to content in DLTJ. And last, recent postings by the Jester can be found below the faceted list.

I hope you enjoy your visit. Please feel free to leave comments where you'd like or contact me directly.

Resource for Improving Higher Education Instruction

A few months back I referred to a project that used video to present information about accessibility needs in the classroom. That article was about how difficult it is to create markup for embedded video that is universally accessible and valid HTML. Late last month the larger project that used that work was released. Called the Faculty & Administrator Modules in Higher Education, or FAME, it is a professional development tool for use in higher education with information on how college faculty, administrators, disability service providers, and students can work individually and collaboratively to improve the accommodations, teaching-learning process, and overall campus environment for students with disabilities. The content on the website is broken up into five modules:

Do I Want to be a Warrior in ALA’s Battle?

Today I received an e-mail from ALA asking me to renew my membership. An excerpt of the e-mail is included below. There is a confrontational tone in the message that is very off-putting and also resonates with the reasons why I dislike ALA. My own emphasis added:

Thank you for this past year of ALA Membership. Your membership year ends April 30, 2007 and we invite you to renew online today.

Killing Off Runaway Apache Processes

Well, something is still going wrong on dltj.org — despite previous performance tuning efforts, I’m still running into cases where machine performance grinds to a halt. In debugging it a bit further, I’ve found that the root cause is an apache httpd process which wants to consume nearly all of real memory which then causes the rest of the machine to thrash horribly. The problem is that I haven’t figured out what is causing that one thread to want to consume so much RAM — nothing unusual appears in either the access or the error logs and I haven’t figured out a way to debug a running apache thread. (Suggestions anyone?)

JPEG2000 for Digital Preservation

Last month was an interesting month for discussion and news of JPEG2000 as an archival format. First, there was a series of posts on the IMAGELIB about the rational for using JPEG2000 for master files. It started with a posting by Tom Blake of Boston Public Library asking these questions:

What can I do with a JPEG200 that I can’t do with a TIFF, a good version
of Zoomify, and a well-designded DAMS?

Don’t you need to rely on a proprietary version/flavor of JPEG2000 and a
viewer to utilize its full potential?
