Fall garden work with Ishtar blazing in the headphones

I am raking autumn leaves and daydreaming while listening to Ishtar
singing...
"C'est la vie, no one ever said life is fair, just a passing of time
that we share... No one said love was fair, just the tears and the
laughter we shared, no regrets I swear!"

One day soon when I am a multi-millionare I'll travel to Spain to
learn flamenco guitar, find a guitar master, go to Cuba and find the
most sensual, heart moving rythm band ever, go to Brasil and find
singer who will whisper Portuges directly to my soul, go to Morroco
and mix in a little flavor of hot Saharan longing. I take them all
somewhere in southern Spain, we will eat, drink, laugh for days,
become good friends and compose and record music.

This is one of the things I want to in my life.

Now, back to raking leaves, getting cold on this island, err park bench.

Compilation issue with gwt-dnd-2.6.5.jar - Java 1.6

Recently I had to use an updated version of gwt-dnd-2.6.5.jar with Snow Leopard (Mac OS X 10.6). I was using Java 1.5 and I got below error, which indicates a class being compiled with a different Java version:

java.lang.UnsupportedClassVersionError: Bad version number in .class file

Solution: It turns out that gwt-dnd-2.6.5.jar is using Java 1.6, therefore I had use same Java version (Java 1.6) in my environment in order for my project to comile correctly.

1. Click Eclipse -> preferences -> Java -> installed JRE

Oh Captain, my Captain! Walt Whitman

O Captain my Captain! our fearful trip is done,
The ship has weathered every rack, the prize we sought is won,
The port is near, the bells I hear, the people all exulting,
While follow eyes the steady keel, the vessel grim and daring;
But O heart! heart! heart!
O the bleeding drops of red,
Where on the deck my Captain lies,
Fallen cold and dead.

O Captain! my Captain! rise up and hear the bells;
Rise up--for you the flag is flung for you the bugle trills,
For you bouquets and ribboned wreaths for you the shores a-crowding,
For you they call, the swaying mass, their eager faces turning;
Here Captain! dear father!
This arm beneath your head!
It is some dream that on the deck,
You've fallen cold and dead.

My Captain does not answer, his lips are pale and still;
My father does not feel my arm, he has no pulse nor will;
The ship is anchored safe and sound, its voyage closed and done;
From fearful trip the victor ship comes in with object won;
Exult O shores, and ring O bells!
But I, with mournful tread,
Walk the deck my Captain lies,
Fallen cold and dead.

Why Nobody Cares About Your Blog

If I walked into a crowded mall, went into the food court, stood there in the middle of it and just started talking, what do you think would happen?

Most people wouldn’t see me. Then, a few would and they would probably think I was crazy. At the end of the day, I’ll just be that crazy guy they saw at the mall.

speak TO your audience no AT your audience
personal relationships still apply
your job is to have something worth saying to your audience
get them to talk back to you
establish authority in the field
become their trusted friend

Future of microblogging? Corporate Twitter, geo-tagging?

In a move that appears to signal an attempt by Twitter to finally monetize its user base, the company will start selling corporate accounts to brands by the end 2009.

Though Twitter co-founder Biz Stone had hinted at such an initiative earlier this year, he fleshed out the concept this week at an industry event in London, where he said a pay-for package will offer verified streams and analytics.

Foursquare the next Social Media craze

Pete Cashmore: Early adopters say Foursquare could be 2010's big social-media craze

Birthed by the team that brought us the mobile social network Dodgeball (acquired by Google in 2005 and later shuttered), the location-based mobile startup serves a simple purpose: It lets an individual share his or her location with a group of friends.

Foursquare ventures beyond utility, however: It's a virtual game in which participants earn badges for checking in at various locations; those that check in most become a venue's "mayor." By all accounts, this mechanism is as addictive as Twitter, Facebook or checking your e-mail on a BlackBerry.

Cloud-based IDE for Google AppEngine?

With all this talk about Chrome OS and Netbooks being stripped down to bare minimum developers must be wondering...

Can I carry a small (CPU/memory) tablet computer (preferably Mac, or Android), connect it to any keyboard and monitor (mouse not needed as tablet would serve as a touchpad) and continue my code development?

Hence the idea...

Anyone interested in writing cloud-based IDE (like Eclipse) for browsers (or Android/Chrome OS platform)?

kind of code-friendly wiki model with "deploy" button added
all the programing happens in the browser
no extra tools needed (can work from school lab/library computer)
apps inherently live in/deploys to Google AppEngine or other cloud
no need for code checking out/in
version history would be auto-maintained
multiple people can edit a file and live editing would be color coded
login for client projects, but open source project could thrive on it
100% same environment for all developers (dependency management)
ability to lock-out files until developer works out the bugs
ability for other to see "locked-out" changes

Now, I know, even today you can open JavaScript, PHP, or other script in the browser, edit it save and instantly see the changes.

Well, I was hoping for GWT or Flex solution.

new facebook4gwt Version 1.0.6

I have made changes in preparation for the December 20, 2009 deprecation of the showFeedDialog() method.

Users should use streamPublish() instead.

Example of use:

FacebookStory story = new FacebookStory();

story.putData("name", "title"); //you can use {*actor*} which uses the logged users name

story.putData("caption", "tehasdsasdf");

story.putData("description", "tehasdsasdf");

story.putData("href", "http://www.cnn.com");//adds href for 'name'

More GWT Date woes

So, as we all know, working with dates in GWT is not much fun given the lack of a Calendar class to do any sort of date manipulation. Incrementing and decrementing dates must now be done by adding and subtracting from the milliseconds that have elapsed since epoch.

So we have a method that does the calculating for you and it has been working fine, until I stumbled upon a very interesting bug. Apparently, there is some issue revolving around November 1, 2009. Here some some code to replicate my results:

public void onModuleLoad()
{
DateTimeFormat format = DateTimeFormat.getFormat("dd/MM/yyyy H:mm:ss");
String dateString = "01/11/2009 1:30:30";

Date originalDate = format.parse(dateString);
Date date = new Date();

for (int i = -7; i < 8; i++)
{
date = incrementDays(originalDate, i);
System.out.println("DateUtil.incrementDay(" + i + ") = " + date.toString());
}
}

private static Date incrementDays(Date date, int xdays)
{
long time = date.getTime();
time = time + (xdays * 24 * 60 * 60 * 1000);

Date newDate = new Date(time);
return newDate;
}

Here is the output from this test:

DateUtil.incrementDay(-7) = Sun Oct 25 02:30:30 CDT 2009
DateUtil.incrementDay(-6) = Mon Oct 26 02:30:30 CDT 2009
DateUtil.incrementDay(-5) = Tue Oct 27 02:30:30 CDT 2009
DateUtil.incrementDay(-4) = Wed Oct 28 02:30:30 CDT 2009
DateUtil.incrementDay(-3) = Thu Oct 29 02:30:30 CDT 2009
DateUtil.incrementDay(-2) = Fri Oct 30 02:30:30 CDT 2009
DateUtil.incrementDay(-1) = Sat Oct 31 02:30:30 CDT 2009
DateUtil.incrementDay(0) = Sun Nov 01 01:30:30 CST 2009
DateUtil.incrementDay(1) = Mon Nov 02 01:30:30 CST 2009
DateUtil.incrementDay(2) = Tue Nov 03 01:30:30 CST 2009
DateUtil.incrementDay(3) = Wed Nov 04 01:30:30 CST 2009
DateUtil.incrementDay(4) = Thu Nov 05 01:30:30 CST 2009
DateUtil.incrementDay(5) = Fri Nov 06 01:30:30 CST 2009
DateUtil.incrementDay(6) = Sat Nov 07 01:30:30 CST 2009
DateUtil.incrementDay(7) = Sun Nov 08 01:30:30 CST 2009

As you can see, at November 1, the time gets decremented by one hour. I have not been able to figure out what exactly is causing this. I have run a ton of tests and have not been able to come up with any answers. All other dates in 2009 appear to work (although, I did not test them all). Also, November 1, 2010 does work, but it is off again on November 8.

Just another reason why we need a Calendar class for GWT.

If anyone has any ideas what is causing this, please let us know.

UPDATE:

Day light savings time did not cross my mind, and is seems to be the culprit in this issue. If anyone has any other ways of calculating the date on the client side in GWT, let us know. Thanks.

UPDATE #2:

Here is the new incrementDays() method to deal with this issue:

private static Date incrementDays(Date date, int xdays)
{
long time = date.getTime();
time = time - (xdays * 24 * 60 * 60 * 1000);

Date newDate = new Date(time);

Integer dateHour = new Integer(DateTimeFormat.getFormat("H").format(date));
Integer newDateHour = new Integer(DateTimeFormat.getFormat("H").format(newDate));
if (!dateHour.equals(newDateHour))
{
if (dateHour > newDateHour || (dateHour.equals(0) && newDateHour.equals(23)))
{
time = time + (60 * 60 * 1000);
newDate.setTime(time);
} else if (dateHour < newDateHour)
{
time = time - (60 * 60 * 1000);
newDate.setTime(time);
}
}

return newDate;
}
