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.

Blocking /xmlrpc.php Scans in the Apache .htaccess File

Someone out there on the internet is repeatedly hitting this blog’s /xmlrpc.php service, probably looking to enumerate the user accounts on the blog as a precursor to a password scan (as described in Huge increase in WordPress xmlrpc.php POST requests at Sysadmins of the North). My access logs look like this:

176.227.196.86 - - [04/Sep/2014:02:18:19 +0000] "POST /xmlrpc.php HTTP/1.0" 200 291 "-" "Mozilla/4.0 (compatible: MSIE 7.0; Windows NT 6.0)"

By itself, this is just annoying — but the real problem is that the PHP stack is getting invoked each time to deal with the request, and at several requests per second from different hosts this was putting quite a load on the server. I decided to fix the problem with a slight variation from what is suggested in the Sysadmins of the North blog post. This addition to the .htaccess file at the root level of my WordPress instance rejects the connection attempt at the Apache level rather than the PHP level:

2nd Workshop on Sustainable Software for Science: Practice and Experiences — Accepted Papers and Travel Support

The conference organizers for WSSSPE2 have posted the list of accepted papers and the application for travel support. I was on the program committee for this year’s conference, and I can point to some papers that I think are particularly useful to libraries and the cultural heritage community in general:

Kuali Reboots Itself into a Commercial Entity

Did you feel a great disturbance in the open source force last week? At noon on Friday in a conference call with members of the Kuali community, the Kuali Foundation Board of Directors announced a change of direction:

We are pleased to share with you that the Kuali Foundation is creating a Professional Open Source commercial entity to help achieve these goals. We expect that this company will engage with the community to prioritize investments in Kuali products, will hire full-time personnel, will mesh a “software startup” with our current culture, and will, over time, become self-sustaining. It enables an additional path for investment to accelerate existing and create new Kuali products.
