Visualizing the global distribution of Evergreen installations from tarballs

In August I made a map of Koha installations based on geolocation of the IP addresses that retrieved the Koha Debian package. Here’s an equivalent map for Evergreen: As with the Koha map, this is based on the last 52 weeks of Apache logs as of the date of this post. I included only complete downloads of Evergreen […]

Visualizing the global distribution of Koha installations from Debian packages

A picture is worth a thousand words: This represents the approximate geographic distribution of downloads of the Koha Debian packages over the past year. Data was taken from the Apache logs from debian.koha-community.org, which MPOW hosts. I counted only completed downloads of the koha-common package, of which there were over 25,000. Making the map turned out […]

Securing Z39.50 traffic from Koha and Evergreen Z39.50 servers using YAZ and TLS

There’s often more than way to search a library catalog; or to put it another way, not all users come in via the front door.  For example, ensuring that your public catalog supports HTTPS can help prevent bad actors from snooping on patron’s searches — but if one of your users happens to use a […]

Three tales regarding a decrease in the number of catalogers

Discussions on Twitter today – see the timelines of @cm_harlow and @erinaleach for entry points – got me thinking. In 1991, the Library of Congress had 745 staff in its Cataloging Directorate. By the end of FY 2004, the LC Bibliographic Access Divisions had between 5061 and 5612 staff. What about now? As of 2014, the […]

Henriette Avram versus the world: Is COBOL capable of processing MARC?

Is the COBOL programming language capable of processing MARC records? A computer programmer in 2015 could be excused for thinking to herself, what kind of question is that!?! Surely it’s obvious that any programming language capable of receiving input can parse a simple, antique record format? In 1968, it apparently wasn’t so obvious. I turned […]

Notes on making my WordPress blog HTTPS-only

The other day I made this blog, galencharlton.com/blog/, HTTPS-only.  In other words, if Eve want to sniff what Bob is reading on my blog, she’ll need to do more than just capture packets between my blog and Bob’s computer to do so. This is not bulletproof: perhaps Eve is in possession of truly spectacular computing capabilities or […]
