Protecting Against OpenSSL SSLv2 Flaw

The recent flaw in OpenSSL (versions prior to 0.9.7h and 0.9.8a) highlights the fact that SSL is not a security panacea. (You can get more information about this flaw from the link above, from this eWeek article, or from this Netcraft post.)

Bluetooth Interfering with GPRS on my Treo 650

Some time ago, I noticed while using my Treo 650 that I could not perform a HotSync operation via Bluetooth while I had a GPRS connection active. As if that wasn’t enough, I’ve discovered what appears to be a further incompatibility between these two wireless technologies.

Just in Case

I’ve mentioned the bug discussed in KB905809 several times in this blog. In reading those posts (or reading the KB article), you’ve probably seen that you can use the SC.EXE command to set the security descriptors on the Service Control Manager to fix the bug. What happens, though, if you mess up the SC.EXE command?

An Interesting Viewpoint

I don’t know that I necessarily agree with his viewpoint, but in “A fake freedom”, the question is raised: Do we really own our data?

Open Source on Mac OS X

Most people automatically equate “open source” with Linux or Apache. But there’s more to open source than that. There are a wide variety of open source projects that are also targeted at (gasp) Microsoft Windows and Mac OS X.

Moving Back to Desktop Manager

Over the last few days or so, I have been experimenting with Virtue, a virtual desktop application. I’ve used various virtual desktop applications since switching to Mac OS X (see this blog posting). After getting used to the lack of a desktop pager, I was really beginning to like Virtue and it’s functionality, even though it seemed as though the Virtue project had slowed and/or stopped development. Finally, after searching around for some way of re-instating the “Run Application” feature in Desktop Manager, I found that Virtue was incompatible with Mac OS X 10.4, aka “Tiger.” Since I’ve been researching the possibility of an upgrade to Tiger, I decided I’d better switch back to an application that was supposed to run under Tiger (which, based on what I’ve been able to find, Desktop Manager does).

Linux on Laptops

Over the past few months, I’ve had the opportunity to install Fedora Core 3 (FC3) on three different laptops from three different manufacturers. So far, FC3 has installed and performed without a hitch. The install went flawlessly on all three systems, the video cards and laptop screens were detected and configured correctly, and an old 802.11b PC Card I had laying around was detected without any problem.

Initial Information on XC Connect

As you may recall, the idea behind XC Connect is that multiple applications across platforms could synchronize data with each other. This would make it possible, for example, for a list of Contacts normally managed inside Outlook to also be shared seamlessly with Linux systems running Evolution and Macintosh clients running iCal. This synchronization would also be possible, in an encrypted fashion, across the Internet.

Virtual Desktops on Mac OS X

Almost from the moment I switched to Mac OS X, I started looking for an application to provide the functionality of virtual desktops. I suppose my days of dabbling with Linux and the X Window System had ingrained me to believe that a *nix-based system just wasn’t the same without virtual desktops.

From PGP to S/MIME

Not long after switching to Mac OS X, I also started using PGP to provide a digital signature to all my business-related electronic communications. Given the increasing frequency of e-mail messages with spoofed source addresses, I felt that it was only prudent to start providing customers with a way of proving that messages which stated they were from me were actually from me. Besides, that might also cause some customers to ask, “Is this something I should be considering as well?”
