Plug and play: Canon N656U

Last night I tried to connect my Canoscan N656U to a computer.

First, I tried the Mac. Connecting the device did nothing. Pushing the button on the device did nothing. A search of Canon's website revealed a driver, but the installer seems to have been written by rabid monkeys. Eventually, I discovered how to make the installer work (you need to already be running on an admin account, because it doesn't know how to authenticate) and restarted, to find... still nothing.

So after a few minutes of that, I decided to try to install on my Windows desktop. This worked a little better right from the start, as Windows at least noticed there was something there. I had to download a driver from Canon's website and use some trickery to install it, but a few minutes later the scan button is launching Picasa2.

Verdict: Canon's installers suck. Completely on Mac, almost completely on Windows.

Visual Studio vs. Xcode

Working with Xcode and Visual Studio on a day-to-day basis, it's natural that I'd compare the two tools. The following is not intended to be an unbiased comparison. These are my opinions only. They're based on how I work, and how I expect tools to work.

Project Configuration: Xcode

Xcode wins cleanly for its configuration editor, which can display all settings at once, predefined groups of settings, or only customized settings. Visual Studio, by comparison, can only display predefined groups of settings. Putting Xcode even further ahead is its ability to filter the settings view as you type. Visual Studio gets some points for having a more capable path editor, but that's really all it has going for it.

Subprojects: Visual Studio

Visual Studio does Xcode one better by showing all the details of the subprojects, including exactly which sources make it up, right in its solution explorer.

Editor: Xcode

Xcode scores a weak win here for having more useful keyboard customizations available. Part of this is the additional meta key available on the Mac.

Window Management: No winner

Visual Studio offers more in the way of window management, but the options are not ones I find useful. On the other hand, Xcode offers more styles of working, but I only use one of these as well. Comparing Visual Studio's style with Xcode's, I see no advantage to either.

Stability: Xcode

Visual Studio's Intellisense is worse than useless, making it impossible for me to work unless I use an undocumented trick to disable it. A quick Google search shows I'm not the only one having problems.

Price: Xcode

Xcode is free. Visual Studio isn't. Adding a replacement for Intellisense makes Visual Studio even more costly. (Swapping out hardware to prove to management that Visual Studio was the culprit and not my system made it even more costly.)

CVS: Visual Studio

Visual Studio does not include CVS integration. Xcode's CVS integration does not work for me. It would be a draw, except that Xcode's textual project files have minor differences when the project is cleaned vs. built. (I've been told this will be fixed in Xcode 3.)

Menu Layout: Xcode

Xcode provides a more logical menu layout, with fewer regularly used commands in sub-menus. In particular, Visual Studio banishes search/replace tools to a sub-menu of Edit. Visual Studio offers a way to customize menu commands, but I'd much rather have a logical if locked layout.

Source Search Tools: No winner

While I find Xcode's search tools more useful, both sets are so pathetic that I refuse to give it a win here.

Are we talking about the same Visual Studio?

Every time someone tells me how great an IDE Visual Studio is, I wonder if we're talking about the same Visual Studio. Just to be clear, the one I'm using is from Microsoft.

Here's an error message I ran into today. See if you can guess what it means; it occurs when you try to drag a source file into your project.

Visual Studio Error

The text, in case you don't want to look at the picture closely, is "A file, filter, or folder already exists at the current scope in project 'calc' or access was denied for the desired operation."

Give up? It means That file is already in your project. It does not mean it is in any particular place in your project, and the group it is in is probably hidden.

I hate overloaded error messages. I hate overloaded error messages where each overloaded error message makes no sense even more. I call for the head of whoever wrote that message! I'm not singling him out; I want the head of everyone who writes useless error messages. And yes, I know that includes my own head, but I've already got it, see...
