Invitations and the VCard Format

My next goal for the Themis project is to parse an invitation from an email. I am starting with invitations generated by MS Outlook because that’s my target audience, but a peak inside of a Google Calendar invitation gives me hope that I’ll be able to support multiple calendars without much trouble. Outlook invitations are sent in the VCalendar format, content type “text/calendar”. The standa...

64-bit IIS vs. 32-bit Assemblies

I found my first 64-bit bug at work. I was moving a windows service built for the ‘Any CPU’ to a 64-bit server. It started fine on the new server, and gave no indication of poor health in the logs, but one key function was malfunctioning. I’m not exactly sure what the cause is, but I know that the hash of any binary file was resulting in the same value. The service does some direct memory manipula...

SQLite vs. SQL CE 3.5 with Entity Framework 4

My wife and I have been taking a Japanese class. I’m enjoying it quite a bit, even though learning languages has never been easy for me. I need to work hard to memorize all the new words, and that means lots and lots of practice. My wife bought a pack of index cards. This is what a normal person would do. To me, it seems like defeat. Why use paper when there’s a computer in the room? While she’s a...

IE9 Try and Fail

I decided to give IE9 a try. What’s not to like about a browser that’s supposed to be faster, cleaner, and support new HTML features? They really nailed the faster and cleaner parts. I didn’t find the user interface in IE8 too busy, but seeing the improvement I’m happy for the extra space. Plunking a site onto my task bar like it were an application is pretty awesome. There are a couple of website...

Themis: System Design

I’m charging forward on the Shared Resource Schedule Service. There are a lot of things I’m getting into place before I start writing code. Don’t try to tell me that I’m not being agile either, you always need to design a little to write good code. The key to being agile is designing only as much as you need, and being prepared to change your mind later. The NameThe first order of business was to ...

My First Open Source Project

I’ve been spending time on the first part of the shared resource service project: “Receive event invitations by email and send an acceptance email”. I hadn’t considered the difficulty I would face receiving emails. This is the most important part of the application, and if I can’t make it work, there’s really no point to continue. I don’t want to write my own POP3 library, I’ve done that before an...

I was using aniPod click wheelthat I got as a warranty replacement back in 2004.It was good to me, but I felt that it was time to look at other options.If iTunes ran a little better on my PC, I probably would have just bought another iPod without a second thought. HardwareIt took me quite a while to choose a new device. I did look...

SQL Management Studio Express with VS 2010 Express

I had some fun trying to install SQL Management Studio on my home computer over the weekend. I was successful in the end, but it was a rough journey. These seem to be the things that can lead you into my scenario: Windows 7 Visual Web Developer 2010 Express (which installs SQL Server 2008 Express) These are the things I ran into trying to install SQL Management Studio (both from an SQL 2008 stan...

Shared Resource Service Requirements

I want to start my project by dividing up the various things the system needs to do, then put them into the order I plan to approach them. I want to start with requirements that are the most risky and most important to success first, and work my way down the list until I finish with items that are neither risky nor important. This approach gives me several advantages. It’s not an issue in this cas...

Shared Resource Schedule Service

I think I’ve got a new project to work on at home. We’ve got this problem at work coordinating a few shared resources in Outlook (like a couple of meeting rooms and a projector), but we couldn’t find any good solutions out there short of installing Exchange Server. I’ve been wanting to play around with Entity Framework a bit, so this should be a good candidate. Perhaps I can slap a UI on it using ...
