My first taste of Mono on openSUSE 11.1

Verdict: not so tasty

I grabbed all the Mono packages via YaST and installed them without problems. I then fired up monodevelop in a terminal so I could watch for warnings and errors. I'm glad I did.

I won't bore you with screen shots of creating a simple 'Hello world' application. I will say that monodevelop is crashy. For example, without having created anything, I attempted to see what the Classes tab on the left side of the IDE would produce if opened. Normally it should be blank; that's what every other IDE in the known universe shows. Instead MonoDevelop crashed and exited. Hmmm...

After the second startup I created the simple 'Hello World' project as a console program with Gtk# extensions. I didn't add any other code. I then had the project build and run within the IDE. During that entire time I got a stream of error messages, such as the following sample:

I think I'll stick with Java IDEs and emacs. Emacs especially if I want to develop C# on Linux, as MonoDevelop appears to be neither a good editor nor a good IDE. I had thought to install KDevelop, but it's available only built with Qt3/KDE3, and I want a native KDE 4 application, especially with KDevelop. I have half a mind to check out the subversion head and just build it locally. It's currently at alpha 5 release, so that may give me some more excitement.

  1. I'm sorry your MonoDevelop experience hasn't been great so far. I'm not aware of any reported crashers on 11.1, but if you get stack traces, could you please file bugs so that we can fix them?

    It's been a long time since MD 1.0 was released and in many ways the 2.0 alphas are more stable. I'm building MD trunk builds on the openSUSE Build Sevice, which should be relatively stable until 2.0 is formally released. There's even a 1-click install.

    You maybe also find that some problems are fixed by upgrading GTK# to 2.12.6 from the Mono repository.

    FWIW, the particular errors you've pasted in your post can safely be ignored. Various Mono debug files (.mdb) seem to be missing, but they aren't strictly needed for MD. Maybe the stock oS 11.1 has these in separate packages.

A Decade Long Religious Con Job

I rarely write inflammatory (what some might call trolling) titles to a post, but this building you see before you deserves it. I've been seeing this building next to I-4 just east of Altamonte/436 and Crane's Roost for nearly 12 years, and never knew who owned it. Today on a trip up to Lake Mary with my wife I saw it yet again. That's when I told her I wanted to stop by on the way back and poke around the property, and photograph any parts of it if I could.

What I discovered was this still unfinished eighteen story (I counted) white elephant, overgrown with weeds and yet still under slow-motion construction. It looks impressive with its exterior glass curtain walls, but that impression is quickly lost when you see the unfinished lower stories and look inside to the unfinished interior spaces.

A quick check via Google leads to an article written in 2010 by the Orlando Sentinel about the Majesty Tower. Based on what I read in the article it's owned by SuperChannel 55 WA…

first night for the gingersnaps

The first night has passed and the two have managed to survive, in spite of what their tiny hearts might have thought when first arriving. Greebo, the larger of the two, has been in hiding the entire time so far. Ponder has spent the time zipping in and out of hiding spots, checking things out, and learning just how comfortable pillows are for resting your head.

During the night I felt the tiny body of Ponder hitting the bed as he leaped up on the side, and then climbed to the top to run around on top of me. At least once he play-attacked my fingers. He might be small but his claws are still quite sharp.

When I got up in the morning the bowl of cat kitten food was fairly well depleted. It's been refilled and fresh water put in the big dish on the floor. I'm assuming that both Greebo and Ponder are feeding and drinking. I have seen Greebo under the furniture peeking out at me when I went looking for him. I'm leaving him alone while he continues to adjust.

So far the guys h…

cat-in-a-box channels greta garbo

So I'm sitting at my computer, when I start to notice a racket in back. I ignore it for a while until I hear a load "thump!", as if something had been dropped on the floor, followed by a lot of loud rattling. I turn around and see Lucy in the box just having a grand old time, rolling around and rattling that box a good one. I grab the GX1 and snap a few shots before she notices me and the camera, then leaps out and back into her chair (which used to be my chair before she decided it was her chair).

Just like caring for Katie my black Lab taught me about dogs, caring for Lucy is teaching me about cats. She finds me fascinating, as I do her. And she expresses great affection and love toward me without coaxing. I try to return the affection and love, but she is a cat, and she takes a bat at me on occasion, although I think that's just her being playful. She always has her claws in when she does that.

She sits next to me during the evening in her chair while I sit in mi…
