Announcing the Google Calendar Dashboard Widget

In the tradition of writing gadgets for Google Desktop and other Google properties, here's one more from me: the Google Calendar Widget for Mac OS X Dashboard.

A Tale of Two Interfaces

Synergy, a mouse and keyboard sharing utility, has proven insanely useful to us users of multiple machines on a single desk. Think of it as a software KVM switch, but minus the "V" (for video.) You can arrange multiple machines side-by-side and Synergy seamlessly moves the mouse pointer and keyboard input from one machine to another at desktop boundaries. It's a great idea and a great tool.

I use QuickSynergy on my PowerBook and Mac Mini, but later happened to look at the official GUI client on my friend's Windows laptop. It's not often that a user interface provokes a blog post on a Monday morning, but this was it.

Here are the screenshots:

You will notice that QuickSynergy has exactly one dialog box (with two tabs, one to use when running as a server, and another when running as a client) plus one About dialog. Synergy has a total of 9 dialog boxes (plus one About dialog.) The question, I wish, the developers had asked themselves, was whether throwing in a dialog box for every single configurable parameter was the right thing to do. It seems like the UI Designer(s) simply gave up on trying to understand the users' needs, and instead just threw everything out to the user: "here, now there's a dialog box for every single line in the configuration file, go figure it all out." In my opinion, that's the designer shirking his or her responsibility of actually designing.

And if there was a savvy user that wanted to, she could just edit the config file! Even as a Computer Science Ph.D. student, I have no idea what the "Relative Mouse Moves" option means, or why I should care about it. (If you say RTFM, that's already the sign of a bad interface.)

Notice how, in the configuration screen, QuickSynergy simply shows you one screen with four text fields on the four sides, whereas Synergy expects you to enter the positions as "Machine X is to Direction Y of Machine Z." The first way is so much more natural, but guess why the Synergy implements the second way? Because the configuration file is written that way.

These are clearly two very different styles of GUI design (though I would strongly argue that a text field for editing a configuration file does not count as a "GUI", it's simply a command-line interface (CLI) inside a text field.) Quick Synergy puts the user first, and is designed to let the user work naturally with his/her mental model of a keyboard/mouse layout. Synergy starts from the configuration file and slaps on a UI on top of it. Thus, Quick Synergy comes closer to the user, while Synergy stays closer to the machine.

UI Design is not about letting users edit configuration files, it's about letting them do what they started out to do. That a config file needs to be edited to make that happen is a side story.

I Fixed A Computer

The headline of this post isn't newsworthy at all. And the rest of the post is probably not newsworthy to a lot of people who read this blog. But I fixed a computer.

So, to fix it, my laptop connected to my cellphone via Bluetooth, which connected to a celltower via GPRS, which sent my SSH packets over TCP/IP to another university machine inside the firewall, from which I then SSHd to the sick machine, and fixed it. The irony is that the problem was with the machine's network interface! The latency was nothing to be proud of, but was pretty usable.

This is probably the setup with the maximum number of different devices and protocols that I've ever used, hence it warranted a blog post. :)

Marathi Newspaper “सकाळ” Reports on Google Desktop

“सकाळ”, ("The Morning"), a popular newspaper in my native tongue, ran a piece on Google Desktop. I’m not a regular reader, but my attention was drawn to it by several friends and family, who noticed my name mentioned in it. Now, while I’m not really sure how they got the info, or even where they got it from, it seems to have originated here in California on Google’s Press Day. Well, Andy Warhol was right!

Google Desktop now includes Google Calendar Gadget

A new version of Google Desktop released today. (For those who came in late, I worked on Google Desktop last year, and have been writing plugins for it for some time now.) When Google Calendar released, I wrote a plugin for it too.

Since my plugin was licensed under an open-source license, Google added features to it and included it in the official download. What's more, I even get credited in the source code. Go, Google! -- kudos to the nice people in the Desktop/Calendar teams.
