Ubuntu Review

Approximately in June or July of 2005, I started
weaning myself off of my powerbook G4, and learning
the Gnome environment under Ubuntu (v5.04, now v5.10).
Overall, it's been a terrific experience, and it's looking
like I've come here to settle down.
So I thought I'd summarize my experiences, from my perspective
as a Java software developer, and as a computer user in general.
The Good
Here are a few things I really like in Ubuntu / Linux:
The Gnome Epiphany Web Browser: my favorite browser.
See my blog entry on the subject.
Edutainment + kids games: On linux, one can download a number of games for children that are of high quality from the point of view of the material they cover. Sure, some games like supertux, are just plain fun 'mario brothers' style games. But many can be powerful tools that can hone the brain power of children. Here are some of them:
- kturtle (logo programming)
- gcompris
- tuxmath / tuxtyping
My kids and I also very much like supertux, tuxracer, and tuxkart. I'm particularly proud of my 3 year-old who is now a supertux champion and has mastered the arrow keys, the enter key, the control key, and spacebar.
Quality open source desktop applications. Who said that open source can't produce desktop apps of higher quality than their commercial counterparts. If you thought the adobe had the best vector graphics editing application, take a look a inkscape. For pictures, check out the beauty of f-spot. For spreadsheets, I think gnumeric is terrific.
Authoring tools. A number of different technologies can be used to write books or articles. Docbook is one and docbook support in the form of toolkits, documentation, utilities and more is the strongest on linux. Many love LaTex.
I particularly appreciate lyx, a wonderful wysiwym editor that does all the heavy lifting for you. If you're about to write a book and don't have in-depth knowledge of docbook or latex, then I believe lyx is the right choice.
Strong pdf support. One can easily produce a pdf version of a document, translate a postscript file to PDF. I recently printed a web page to a postscript file and then translated it to PDF.
editors galores. Lots of editors to choose from. gedit, kedit, kate, jedit, and many more besides.
apt-get and the amazing synaptic package manager.
Want an app? Just wish it and a few seconds later it's completely
installed on your system, along with all its dependencies. That's the magic of the synaptic package manager. apt is the technology that makes it happen and the synatpic front-end gives you no reason to ever fall back to the command line.
strong printer support
- lj3200 which i'd given up on entirely with my mac (hp did not
make apple drivers for this specific version), worked like a charm
with linux, without having to install drivers
- doing duplex printing with my brother 5150D at the office
- doing network printing to an hp inkjet printer
wifi worked for me out of the box.
the sleep feature works just fine but does not conserve the battery charge
nearly as well as my powerbook did. hibernate then is the alternative,
which has worked great for me for many months, up until a recent kernel
update.
strong device support in general: plugged in my camera and automatically
started downloaded photos, without even having to download anything.
amazing endless suite of kde apps. from kontact to koffice, kde is simply
an amazing source of seemingly boundless energy.
kde and gnome apps can run side by side
terrific support forums
java:
- unlike the last OS i worked on, there are no issues regarding obtaining
the latest java udpates on time
- all the java ides work with it: intellij, eclipse, and netbeans
- have the option of building java applications that use the gtk toolkit
latest firefox
- endless supply of artwork for customizing background image,
login manager, login splash, window decorations, icons, and themes
freedom!
no viruses, no symantec, no mcaffee
complete desktop customization features, especially with kde, although in the end i prefer gnome; i find myself forever tinkering on kde, and more productive on gnome. each has their strengths and together they make for an even better distribution: a wider array of choices; sometimes you get this feeling though that the velocity on the kde projects is just so amazing..
i love the ability to assign keyboard shortcuts to anything
i rarely touch the mouse and am in complete control
ruby. if you're doing ruby development, installing the toolstack, including rails is a snap.
cost. i don't have to pay for additional apps. my notebook cost me approximately 1/3 the price of my last one.
The Bad
- projector support is not really there like it is on a mac
- sleep does not conserve battery well
- had some hickups with hibernate after a kernel update
- have some weird totem/video problems at the moment, though there's no lack
of video players for gnome or kde, this one happens to be the default and
for some reason hangs when attempting video playback
Summary
The main reason I switched to ubuntu is that I can now compile and launch
my java apps in 1/2 to 1/3 the time it used to take me on my last laptop.
I used to run a 1GHz powerbook G4. Now I run a 1.7GHz intel centrino
(same amount of ram on both). That's a serious advantage.
Finally, contrary the general perception, I don't compile my gnome apps
or kernel. I download and install precompiled binary distributions of
all my apps.
I'm very satisfied with Ubuntu and in the event that you're looking for
the right home, I hope this short review was helpful.
An Epiphany

Everyone stands behind their favorite web browsers.
Firefox definitely appears to be at the forefront.
But then you come across people who prefer Camino,
for example, which is a web browser that uses the
Gecko layout engine but taylors its user interface
to fit the MacOSX mold, so to speak. Camino
indeed is pretty cool and pretty fast. If you run
macosx, you should definitely check out Camino.
In a similar vein, I recently (maybe two-three months
ago) came across Epiphany..and i'm in love.
Epiphany is to Gnome what Camino is to MacOSX: a web
browser that uses Gecko but its UI uses the Gnome and
GTK APIs for a user interface. Epiphany was designed to
fit in on a Gnome desktop. Indeed, it is the endorsed
web browser for Gnome.
But that's not the reason I so love Epiphany. Epiphany's
philosophy appears to be along the lines of stay out
of the user's way and less is more.
So, beside the fact that Epiphany has the following
favorable traits:
- it just works
- it has a simple, minimal menu structure
- it supports tabbed browsing
- it highlights bits of strings on a page when doing
incremental find's
the feature that really speaks to me is the design of its
bookmark system and the way in which you can customize
the browser with actions for URL handling without having
to write any code.
This is subtle but a most wonderful feature. Allow me
to illustrate.
When you launch Epiphany, you won't find two text fields
at the top edge of the window: one for the URL address
and another for doing the Google search. Instead you'll
find a single text field where the URL address is entered.
How then does one perform a Google search without having to
first visit google.com? By writing a plugin. Here's how:
- visit google.com
- enter a search string, for example: testing
- bookmark the search results:
name the bookmark "Google this"
- edit the bookmark: in the url string, replace
the word "testing" with "%s". You've just parametrized
the URL. save the bookmark.
Now, open a new browser window and type "java" in the
URL field. You'll notice that a pull down menu will appear
containing the option "Google this." Selecting
that option will automatically visit the google search
URL, replacing that "%s" in that bookmarked url with
the search string you entered in the url field.
It's a dynamic bookmark.
How wonderful! In my browser, I've configured four such
dynamic bookmarks: google search, wikipedia search,
dictionary search, and ashkelon search. So now when
I'm coding I can just type in the url field: "String*"
and select the 'ashkelon search' option from the
Epiphany context menu, et voila: i get my ashkelon
(javadoc) search results.
In addition to this cool search feature, if you type a substring
of the name of a bookmark in that magic url field, that bookmark
will show up in the context menu as well.
If you do use Gnome, I highly encourage you to give Epiphany
a try. It's a stable and robust browser. But just as importantly
it's well-designed. If you don't use Gnome but would like to
give it a whirl, I strongly recommend the ubuntu distribution.
Last note: Epiphany also works on KDE.
