(These steps assume you already have a version of Eclipse installed under /opt.)
Like this:
$ wget http://ftp.osuosl.org/pub/eclipse/technology/epp/downloads/release/ganymede/R/eclipse-jee-ganymede-linux-gtk.tar.gz
$ tar xzvf eclipse-jee-ganymede-linux-gtk.tar.gz
$ cd /opt
$ sudo mv eclipse eclipse-europa
$ sudo mv ~/eclipse . You should now be able to launch Eclipse Ganymede using the same shortcuts or scripts as before.

Being a “Class A Nerd,” that fact that my battery has only lost 2% of its original capacity in 69 months of continuous use pleases me to no end.
Increasingly the places where I work required frequent password changes. And the new password policies also tend to stipulate lengthy, complicated passwords. “Must contain upper and lower case letters, numbers, symbols, et cetera.” The kicker is not being allowed to repeat a password for so many iterations.
Developing a good 8 - 12 character password isn’t too hard, but having to come up with one every month (or two or five) and not being allowed to repeat them until six or seven expirations periods have passed, is painful. (In one case passwords couldn’t be repeated for 15 months.)
So I developed a pattern on the keyboard that allowed me to create a new password that met the most stringent of pattern requirements, with the bonus of being flexible. I could simply adjust the starting point and have a new password in seconds.
Problem solved.
Well, almost. You see I want an iPhone. I’ve been to the Apple store numerous times to play with the displays and I am hooked. There’s only one problem. The touch keyboard only displays letters or numbers and symbols. Moreover, the physical relationship of the keys isn’t quite the same as on a standard 102-key keyboard. My password pattern is broken by the input device.
Time to develop a new password pattern, or convince the various powers-that-be in my professional life, that once I’ve created a strong, 12-character password that utilizes capitalization, numbers and symbols, there is really no need to constantly change it.
With the release of Wordpress 2.6 this week I was preparing to update both my test sites and our public sites using the rsync method I wrote about in April. Quite by happenstance I read an article on Download Squad about the Wordpress Automatic Updater plugin, and decided to give that a try instead. In short it worked perfectly.
After downloading the plugin and installing it, I was able to upgrade each site from version 2.5.1 to 2.6 in a matter of minutes. I opted to use the manual progression through the upgrade process, which is nicely laid out. After verifying that my server would allow the plugin to work, backups were made of my Wordpress installation and content database. The database backup allowed for dumps of add-on tables, which was very thoughtful. After turning maintenance mode on, and disabling all the active plugins, except for itself, the plugin downloaded a copy of the latest release from Wordpress, unzipped it, and then installed it. Wordpress Automatic Updater even allowed for the possibility that the underlying database structure would change as a result of a new version, and provided a link to a new browser page that let me trigger a database update.
At the end of the process a log file was displayed with a complete record of all the activities completed, and the I was given a option to clean up the temporary files created by the process.
Except for some mildly stilted (English as a second language?) phrasing in some of the prompts and informational messages, I found nothing about the plugin not to like. An excellent addition to Wordpress, and one I highly recommend.
Ever since getting my first Palm Pilot many years ago, I have been a big fan of electronic books. First with Peanut Press, and now with eReader, I have collected nearly 400 electronic books. The diminutive screen size has never bothered me, and I have enjoyed the portability and availability of having one, or two, or twelve, books in my pocket.
I was quite pleased to discover that the folks at eReader have ported their reader application to the iPhone and iPod touch through the new Application Store. The embedded video below demos the features on a new iPhone.
I am looking forward to the day when I can have one of these wonders in my pocket.
When I was a child going to the grocery store and watching the bag boy work was always fascinating to me. Standing at the end of the conveyer belt, he sorted items into different bag. Some items were shunted aside for later bags, occasionally an item was repositioned in a new bag. They were fast and efficient, able to keep up with the checker, and having everything in the cart ready to be wheeled to our car by the time my mom had paid and gotten her change and receipt.
Today stores like Walmart have done away with the bagger; putting the bags on a rotating stand next to the checker, so that he or she can scan the item and deposit it immediately in a bag. The layout of their workstation doesn’t lend itself to the priority sorting the bag boy of my youth was able to perform. There isn’t a place to set things aside until enough items of similar consistency, fragility, or heft are amassed and ready to be bagged.
Moreover, it seems that few of these people paid attention when they were last in a store that employed baggers. Even when we position items on the belt in logical bag groupings, they seem to be able combine in the worst possible ways. Bananas in a bag with soup cans. Frozen, and therefore covered with condensation, items with dry goods that hadn’t ought to get wet at all.
Some, higher end stores, still have the bagging station at each check out lane, but often as not there isn’t a bagger there, leaving the checker to do both jobs. I almost always position myself at the bagging station and start filling bags, in part to speed things up and in part to fulfill the brief childhood dream of being a bagger. Even at these stores, the baggers seem not to quite understand their responsibilities. These items are no longer the stores, they have been bought and paid for by the customer, and should be treated with respect.
Bagging, I fear, is a dying, soon to be lost art.
When I was a child I was given a large set of wooden blocks. The set included a huge variety of sizes and shapes, and I spent many happy hours building any number of things with them. My favorite activity was to build large towers; some required that I stand on a chair to add the upper layers. Once the tower was complete I’d tie several newspaper rubber bands together and start attacking various supporting structures, until the whole thing came crashing down. Followed shortly by my mother calling downstairs, “What was that?! Are you alright?”
Today, as a software developer, I play with different blocks, but the underlying idea is the same: build useful structures that can withstand unexpected outside pressures. Developing applications in Java, with or without HTML front-ends, requires an amazing number of blocks just to get started.
Assuming that your operating system is stable (a dangerous assumption to make, perhaps), the first block necessary is a JDK, or Java Development Kit. Sun provides these, and a nifty installer to put it on your machine. Of course there are various flavors of Java (SE, ME, EE) and versions within those families; choosing the right block is important.
With a JDK installed, and a simple text editor you are ready to go. Two, maybe three blocks - low and stable. Unfortunately, while simple, this basic arrangement forces you to do most development chores by hand. Automation is the key to success here. Or at least the key to the appearance of success.
Oh, and calling Java “a block” is a bit disingenuous. Java is a vast collection of libraries, concepts, and intricate dependencies. Abstracting Java to just one block is useful in polite conversation; the reality is that it represents an incredibly complex array of blocks.
After laying down the Java block, or blocks, the next piece is a good IDE, or integrated development environment. There are several major players in this market segment, however the one I am most familiar with is Eclipse, so I’ll use it for our discussion. As with Java, Eclipse (or any other IDE) is usually thought of as one block, when it is really a complex collection of blocks. Adding to the fun are plugins; small (or not so small) blocks that get inserted into Eclipse to add or augment existing functionality.
Hm. Actually it isn’t fair to call Eclipse a block. It is truly a framework that other blocks are hung off, creating a platform for building software. That the framework itself is a collection of hundreds of blocks is interesting in a recursive, turtles all the way down sort of way. It also adds to the sense of instability building applications with the vast sea of blocks that is Java has already created.
Imagine standing on one box to reach a high shelf. Not too bad, huh? Now image that instead of a nice sturdy crate of a box, you are standing on a platform made of dozens and dozens of tiny blocks, neatly fitted together, but not required or restrained into a coherent assembly. Not a comfortable sensation. Now imagine that you are standing on not one, but two such platforms. That is building Java applications with Eclipse, or any other large IDE.
There are one or two other significant pieces to this puzzle. There is a plugin to manage the versioning of the code between my workspace and the central repository. Also, there is a plugin that resolves dependencies - finds additional code libraries for when your application needs more than base Java provides.
When all the blocks are neatly lined up, and the weight of your development is properly supported, you can build great things. When one or more of the blocks gets out of position, however, disaster can (and does) strike.
I spent the day yesterday building a new service, a simple data access object (DAO) to read data from a table and build an single object containing all the information about an entity. Just a handful of code, really. In order to vet my code I used a feature in Eclipse to generate a unit test. This new piece of code is specially designed to exercise all the limits of the original code. Of course, the test mechanism requires still more blocks to be shoehorned into our every-growing tower. And when I tried to run the test all I got were nonsense errors.
The errors seem to be saying that some piece of the Java, Eclipse, unit test framework, was out of whack. So now, instead of debugging my application code, I get to debug the platform on which I am trying to build it. Is there something wrong with Eclipse? Or, more likely, one of the plugins currently employed? Maybe the workspace is somehow corrupted. Did I miss a small, but critical configuration setting?
Somewhere, in the tower of blocks that extends from the operating system up through the Java JDK, the Eclipse IDE, with all its plugins, the version control system, and dependency resolution process, somewhere in that vast mass of blocks, one or more is out of place. With no easy way to find it and realign it, the path forward is to knock the rest of the tower over, clean up the mess, and start over fresh.
Today I am rebuilding my environment, fresh copy of Eclipse, re-installing the necessary plugins, re-configuring the variables, and hopefully, eventually, testing my application.
Whether you are a fan or a foe of Walmart, this visualization of their growth is fascinating. I especially like the part at the end where all the projected, future stores are added to the map.
On the playground, when teams are chosen for team sports, there is a definite picking order. The future jocks are almost always the team captains, and their sycophants are rapidly picked next to fill out the roster. Eventually the picking gets down to the kids who can’t throw or run or who are somehow deemed as “better on the other team.” Growing up, I was one of those kids.
While I couldn’t express it in words back then, I know now that there were some unwritten rules in play. Even the society of children has norms and, since mercy is a learned trait, those outside the norm were shunned and pushed aside. Much is made today of nerds, and there appears to be growing acceptance of those who aren’t mainstream. Still, it hurts to be on the outside looking in, especially when the rules aren’t published.
As an adult I have run afoul of these “unwritten rule” situations more than once. It is every bit as painful today as it was on the playground four decades ago. Any group, or organization, develops an immune system as it inoculates itself against foreign bodies - be they people or ideas. Which is all fine and dandy until you are the foreign body.
Sibylle described to me once what it was like to move to the United States, where everyone looked just like the people she’d left behind in Germany, and the bitter lesson of discovering that underneath everything was completely different. For the past 18 months I have experienced a tiny example of that, as I have tried to assimilate into a new group, a group that looked and talked just like me. A group that has rebuffed my efforts to fit in, a group that is treating me as a foreign body.
My only hope is that the next group has unwritten rules that make sense to me, that I am not a foreign body, that I am not the kid who doesn’t know to run on two outs.
For the last 18 months I have tried mightily to become part of a group only to be continually rebuffed and turned aside.

\/\The Conscience of a Hacker/\/

Another one got caught today, it's all over the papers. "Teenager
Arrested in Computer Crime Scandal", "Hacker Arrested after Bank Tampering"...
Damn kids. They're all alike.
But did you, in your three-piece psychology and 1950's technobrain,
ever take a look behind the eyes of the hacker? Did you ever wonder what
made him tick, what forces shaped him, what may have molded him?
I am a hacker, enter my world...
Mine is a world that begins with school... I'm smarter than most of
the other kids, this crap they teach us bores me...
Damn underachiever. They're all alike.
I'm in junior high or high school. I've listened to teachers explain
for the fifteenth time how to reduce a fraction. I understand it. "No, Ms.
Smith, I didn't show my work. I did it in my head..."
Damn kid. Probably copied it. They're all alike.
I made a discovery today. I found a computer. Wait a second, this is
cool. It does what I want it to. If it makes a mistake, it's because I
screwed it up. Not because it doesn't like me...
Or feels threatened by me...
Or thinks I'm a smart ass...
Or doesn't like teaching and shouldn't be here...
Damn kid. All he does is play games. They're all alike.
And then it happened... a door opened to a world... rushing through
the phone line like heroin through an addict's veins, an electronic pulse is
sent out, a refuge from the day-to-day incompetencies is sought... a board is
found.
"This is it... this is where I belong..."
I know everyone here... even if I've never met them, never talked to
them, may never hear from them again... I know you all...
Damn kid. Tying up the phone line again. They're all alike...
You bet your ass we're all alike... we've been spoon-fed baby food at
school when we hungered for steak... the bits of meat that you did let slip
through were pre-chewed and tasteless. We've been dominated by sadists, or
ignored by the apathetic. The few that had something to teach found us will-
ing pupils, but those few are like drops of water in the desert.
This is our world now... the world of the electron and the switch, the
beauty of the baud. We make use of a service already existing without paying
for what could be dirt-cheap if it wasn't run by profiteering gluttons, and
you call us criminals. We explore... and you call us criminals. We seek
after knowledge... and you call us criminals. We exist without skin color,
without nationality, without religious bias... and you call us criminals.
You build atomic bombs, you wage wars, you murder, cheat, and lie to us
and try to make us believe it's for our own good, yet we're the criminals.
Yes, I am a criminal. My crime is that of curiosity. My crime is
that of judging people by what they say and think, not what they look like.
My crime is that of outsmarting you, something that you will never forgive me
for.
I am a hacker, and this is my manifesto. You may stop this individual,
but you can't stop us all... after all, we're all alike.
