The GNOME Web browser Epiphany — formerly based on Mozilla's Gecko engine and now based on Webkit — doesn't ship with Ubuntu (though it does with Debian and most GNOME-based distros/projects).

But if you're running GNOME, I recommend you add it via your favorite package manager.

What Epiphany offers is a streamlined, faster, less-resource-intensive browsing experience.

I have a few Web-delivered apps that absolutely require Firefox, but for as much else as possible, Epiphany does an excellent job and doesn't stress my less-than-new hardware as much as Firefox.

If you run top in a terminal and keep an eye on the running processes, you'll see that Firefox hogs a lot of CPU and tends to keep hogging it even if you're not "actively" browsing. Other browsers, including (in my experience) Epiphany, Opera, Chrome/Chromium, Konqueror, Midori, Kazehakaze (and really just about anything that isn't Firefox) is much more forgiving of system resources than Firefox.

So it pays to shop around for browsers that do what you want yet don't stress your system so much.

Though it's not open-source, I do use Opera on my super-old systems, where it's light footprint makes even my 233 MHz system usable.

I've been pretty happy with Chromium in Ubuntu, and Chrome in Windows runs better now that I have 1 GB of RAM on the XP box (it didn't do so well with 512 MB).

But in GNOME, I've relied on Epiphany as my browser of choice for some time. I didn't find it slow when it was based on the Gecko engine, and now on Webkit it remains fast and functional.

The more I use GNOME, the more I gravitate toward the "GNOME apps," incluiding Epiphany, Evolution (which I've just started using with a couple IMAP mail accounts), the Empathy IM client, Rhythmbox, etc.

While I think the even-tighter integration of GNOME apps in the Ubuntu panel is theoretically a step in the right direction, I find that things are broken enough that the benefits of that integration aren't terrible available at present (but I hope they will be in future).

Note: In the past month or so, I've run GNOME in Debian Lenny, FreeBSD 7.3 and Ubuntus 8.04 and 10.04.

Here's my problem. I need a calendar app that rudely beeps to tell me when to go to meetings and such.

In Ubuntu, that means the Evolution mail client, which has an extensive calendar function, or so I'm told.

But I don't run Evolution. I use Thunderbird to manage my mail, and Thunderbird doesn't have a calendar function ... or does it?

Allow me to digress briefly: I first tried the Orage calendar app from Xfce, which I already have on this Ubuntu box because I have Xfce (but not the full Xubuntu) on it. But Orage, while working generally well for what I need it to do, for some reason is incapable of playing sounds to alert me to ... my alerts.

I did a bunch of Googling, checked bug reports. Nothing about Orage and a lack of sound in Ubuntu.

So I moved on.

I learned about Mozilla's Sunbird project, which is a full-fledged calendering app, and I also learned that there is a Thunderbird add-on called Lightning (Thunderbird and Lightning ... get it?) that brings Sunbird's calendar features to the Mozilla mail client.

Well, I downloaded the add-on, added it to Thunderbird ... and I was unable to create an event. Full stop.

So I backtracked. I removed the add-on and did what I should have done in the first place: I went through the Synaptic Package Manager and added the lightning-extension package, which brings along with it the calendar-timezones and calender-google-provider packages. (Presumably this means Google's calendar can somehow feed off of this ... I'll explore that later.)

I'll repeat for the West Coast audience: If you're running Thunderbird in Ubuntu, downloading and installing the Lightning calendar add-on from Mozilla won't work. Instead use the version in Ubuntu's repository.

Since I generally run Thunderbird all the time for my mail, having my calendar/alerts in there is the perfect solution.

Once I installed the three packages, I started Thunderbird. Right away the app asked whether or not I wanted to import my calendar settings from Evolution. Since I have nothing there, I declined.

Once in Thunderbird, I had Lightning. It works. I did a test event, sound worked, and I'm ready to start creating recurring events and alerting myself to their imminence (and/or eminence).

All this makes me think about the huge value we as users get from Mozilla. I'm waiting for music-manager/iTunes-killer Songbird to get better, and I'm already benefiting from Sunbird in the form of Lightning. ... and that's all on top of Thunderbird and Firefox. Very nice, indeed.

The quick version: To add calendar functionality to Thunderbird in Ubuntu, don't add Mozilla's Lightning add-on directly. Instead, add it through Ubuntu's own repositories, in my case using Synaptic to add the lightning-extension package and its dependencies. Then you'll be calendar-ready in Thunderbird.

The take-away: Don't want to use Evolution (I prefer a true cross-platform application for e-mail, and Thunderbird fits that bill very well) but want calendar functionality in your mail client? Thunderbird and Lightning seem to play well together.
