My fellow cohorts in this e-mail interview were Bob Plankers and Martin MacLeod. The interview questions focused on things like the best way for a sysadmin to get started with virtualization, what skills may be vendor-specific or not, and where virtualization may be headed. It was pretty interesting to participate, and it’s even more interesting to see how Bob and Martin responded to the questions.

I’m pretty boring when it comes to links, actually.  Unlike some other users whose RSS feed of links I watch, my “linkstream” is pretty much focused around specific technology areas (virtualization, VMware, Active Directory, UNIX/Linux, Macintosh) and Christian topics.  That’s generally it.  So when other del.icio.us users start adding links to my Inbox for topics outside those general areas, it doesn’t really make a whole lot of sense to me.  I can certainly see the value of the del.icio.us Inbox; after all, everyone’s view of the World Wide Web is different, and someone else might be able to find information that I can’t find (or vice versa).  So I could see someone putting a link in my Inbox that had to do with Active Directory, UNIX/Linux integration, VMware, or a Christian topic (like an up and coming new Christian music artist or something).  Links that don’t really have anything to do with links that I normally track are just like e-mail messages hawking wares designed to augment portions of my anatomy…they are not useful, helpful, or otherwise valuable to me.  That makes them spam.

Is this just me creating a problem where one doesn’t exist, or are others also seeing the same trends?  And what steps are ones taking, if any, to protect against this?  (Admittedly, it is an extremely low-volume and lower-impact problem right now.  I seem to recall saying the same about e-mail spam years ago.)

Up until now, I’ve used tags primarily as categories, as a way of grouping links (or other content) together.  For example, my Linux tag on del.icio.us contains links that all primarily center around Linux.  That makes perfect sense, but what about links that discuss Linux integration with Windows?  With my old system, that creates a quandary, a conflict that is not necessarily easy to resolve.

Moving forward, I’m going to start using tags more as keywords than categories.  This will mean that more items will have multiple tags associated with them (and that makes sense), but it will also mean more tags than I have used in the past.  This will allow me to more easily tag links and content in such a way that I hope will be more useful to myself and others.

I will continue, however, to attempt to use the same sets of tags across multiple sites and services, just as I do now with my del.icio.us links and my weblog content.

If anyone has any feedback on other ways I can make tagging work more effectively, I’d love to hear about it—perhaps someone out there would care to share their tips, tricks, and techniques?

With the static URLs for permalinks also come static URLs for category archives and feeds.  Unfortunately, it looks like I’ll have to go back and rework any internal links I created in my own posts.

In addition, I reworked the template to include a hyperlink for adding a post’s URL to your del.icio.us bookmarks.  Now you can add an entry to your bookmark list with ease!

Here’s my current list:

  • InterNetNews (INN):  I had an installation of INN up and running a short while back, but had to resort to an ugly hack with stunnel in order to make SSL work from a newsreader.  To get a clean build, I’ve decided I’ll just start from scratch with a clean installation.  I’ll be using CentOS 4.1 again as I work on transitioning all my Linux-based servers to a newer Linux distribution, and I’ll be compiling INN from source instead of using a package.
  • OpenBSD-based antispam gateway:  I’ve got an antispam gateway running right now (uses Red Hat Linux, Postfix 2.1, SpamAssassin, Postgrey, Razor, DCC, and ClamAV), but I want to try building one using OpenBSD 3.8 (just recently released) and newer builds of Postfix, SpamAssassin, and Amavisd-New.  In particular, I’m interested in the advanced integration of newer versions of Postfix and Amavisd-New.
  • XC Connect:  I’ve also mentioned XC Connect before as well, but a previous installation proved to be unstable, and the Apache integration was less than stellar.  In fact, the integration was nonexistent.  I’m going to try a clean build of CentOS 4.1 and XC Connect to see if that will correct the stability and integration problems.

I also need to wrap up the documentation for a few completed items, such as the Cisco VPN integration with Active Directory.  Mac OS X integration with Active Directory is also on the “to do” list, but it will have to wait a little while—I’ll need to find another Mac to “experiment” with instead of using my own PowerBook.

Tests of Windows-to-Windows synchronization are very positive.  The but the real test for me is synchronizing between iCal/Address Book and Outlook.  If that part works as well as what I’ve seen thus far, I will be truly excited.  The idea of having a single list of contacts is more enticing than perhaps I can fully elaborate.

I plan on performing some additional tests this weekend, and when those tests are complete I’ll post more information here.

Then all I have to do is figure out why my Treo won’t synchronize fully with my laptop.

To further complicate matters, it looks like I’ll have to compile INN from source myself in order to get SSL support in nnrpd (that’s the component that handles connections from NNTP readers).  It’s not a big deal, I know.  It’s just my history compiling from source has been a bit rocky.

I have a newsfeed to transfer new postings from the proprietary application over to INN, and I’m using pullnews right now as I write this to transfer the old articles over.  Aside from some limitations and failures which I believe to be the result of the proprietary application’s specific implementation of NNTP (which I, personally, feel is another nonstandard implementation), everything seems to be transferring over rather well.  The next step will be to add authentication to the INN installation, and then add SSL support.

One more nail in the coffin of a certain proprietary groupware application…
