  • DSID-0C090334

    Working with our clients on LDAP configuration almost invariable starts with SSL certificates. Self-signed, intermediate, and take up a while. The two tools, openSSL and keytool have become my friends. Working with a network admin for the client, I finally saw the legitimate certificate correctly signed by the intermediate certificate not the self-signed. This means I…

  • Textarea Backup

    I am going through my software installed on my work computer in order to transfer to a new one. This came to my attention as something potentially relevant to others. A common problem we hear doing web-based learning management system is the web browser crashed before the user could submit a form. The complaints we…

  • If you are a CE/Vista admin, then you should probably be aware of $WLDOMAIN/serverconfs/HtmlSecurity.config. This file has the regex code for blocking inappropriate input by users to exploit forms. Say a student wants to write a mail message to another student with JavaScript to execute malicious code to hijack a session. One of the regexes…

  • Pick Up Line

    (I will never use.) My name’s Vista. Can I crash at your place tonight? Noticed at geekpickuplines. Especially funny for me because the product I run is the Blackboard Learning Management System Vista Enterprise. We just call it “Vista”. (Yes, very confusing when Windows Vista users want to know the compatibility of Vista with Vista. The…

  • Nearly two weeks ago, Google+ launched Pages, a version of a person profile for non-people. (Google does know the Supreme Court deemed corporations people too, right? So corporations should have a person profile.) Companies desiring a social media presence have created a page in addition to their Facebook pages, Tumblr, and Twitter accounts. Over the…

  • I love it when I run across a prediction about the time of the deadline. Jakob Nielsen made one on November 20, 2006 that computers will be 1/4th their current price of $379 in five years. Five years later is November 20, 2011. That is today! In areas like North America, Europe, Australia, and Asia’s advanced countries,…

  • Do not move things right before I click on them. Windows this means you. Opening up a new window steals focus from my mouse to the new one. Opening a new window when I did not explicitly request it and while I am typing or navigating something in order to do something critical infuriates me. Facebook this…

  • Googlewashing

    Surprised the term “Blackboard” has not been Googlewashed to Moodle or Sakai. Or Blackboard doing the same to Instructure. P.S. I am too scared of using the other term and getting more visitors here from the CIA and NSA.

  • One of the questions we ask our clients initiating an engagement to help them setup external authentication from our LMS to their server is, “What is the certificate authority for your SSL certificate?” We have been burned by people purchasing certificates from authorities Java does not support. (And the support is indeed limited compared to say,…
