ezComponents ready for prod?

Harun Yayli — Mon, 11 Feb 2008 17:47:37 +0000

I’m following what ezComponents doing for sometime now.
Quite nice framework for whatever you need.
I gave a try to write a mysql schema sync.
Real easy to write. only 4-5 lines of code to sync schemas.
It would have been great if it was actually working. The outout sql ddl is not runnable in some cases (syntax errors). Or the order of the columns are different.
I’m sure they’ll fix it soon but this tells me they are not yet ready for production quality.

See the code below, maybe I’m doing something wrong.

require_once "ezcomponents/Base/src/base.php";


function __autoload( $className ){

        ezcBase::autoload( $className );

}
$sourcedb['host']= isset($_POST['sourcedb']['host'])? $_POST['sourcedb']['host']:'';

$sourcedb['port']= isset($_POST['sourcedb']['port'])? $_POST['sourcedb']['port']:'';

$sourcedb['user']= isset($_POST['sourcedb']['user'])? $_POST['sourcedb']['user']:'';

$sourcedb['pass']= isset($_POST['sourcedb']['pass'])? $_POST['sourcedb']['pass']:'';

$sourcedb['db']= isset($_POST['sourcedb']['db'])? $_POST['sourcedb']['db']:'';

$destdb['host']= isset($_POST['destdb']['host'])? $_POST['destdb']['host']:'';

$destdb['port']=  isset($_POST['destdb']['port'])? $_POST['destdb']['port']:'';

$destdb['user']=  isset($_POST['destdb']['user'])? $_POST['destdb']['user']:'';

$destdb['pass']=  isset($_POST['destdb']['pass'])? $_POST['destdb']['pass']:'';

$destdb['db']=  isset($_POST['destdb']['db'])? $_POST['destdb']['db']:'';
$ddl = null;

if (count($_POST)>0){

	$sdb = ezcDbFactory::create("mysql://{$sourcedb['user']}:{$sourcedb['pass']}@{$sourcedb['host']}:{$sourcedb['port']}/{$sourcedb['db']}");

	$souceSchema = ezcDbSchema::createFromDb($sdb);
	$ddb = ezcDbFactory::create("mysql://{$destdb['user']}:{$destdb['pass']}@{$destdb['host']}:{$destdb['port']}/{$destdb['db']}");

	$destSchema = ezcDbSchema::createFromDb($ddb);

	$diffSchema = ezcDbSchemaComparator::compareSchemas( $destSchema,$souceSchema );

	$ddl = $diffSchema->convertToDDL( $ddb );

}

?>






 Schema Comparator for MySQL


Compares the source and destination db schemas, gives the DDL to apply to the destination.


















Source Db Server:  Port:
Source Db Username: 
Source Db Password: 
Source Db : 










Destination Db Server:  Port:
Destination Db Username: 
Destination Db Password: 
Destination Db : 










< ?php

	if (count($_POST)>0){

		if ($ddl!=null && count($ddl)>0){

			echo 'USE '.$destdb['db'].";\n";

			foreach($ddl as $lines){

				echo $lines.";\n";

			}

		}

		else{

			echo '-- No diff';

		}

	}

Harun Yayli — Mon, 24 Jul 2006 13:29:09 +0000

Reading this interview is a really good start to monday morning.
The questiongs are directed to the well known and not so well known programmers.

Linus Torvalds – The Linux kernel author
Dave Thomas – Author of the Pragmmatic Programmer, Programming Ruby and other great books about programming. One can read his mainly programming-related thoughts here.
David Heinemeier Hansson – Author of the Rails Framework – the new hot web development framework. He has a weblog here.
Steve Yegge – Proably the least known from guys here, but also made one of the most interestings answers, has a popular weblog about programming. He is also the author of a game called Ã¢â‚¬Å¾WyvernÃ¢â‚¬Â.
Peter Norvig – Research Director at Google, a well known Lisper, author of famous (in some circles at least) books about AI. See his homepage.

Real kick the ball cell phone camera game

Harun Yayli — Thu, 09 Feb 2006 00:32:18 +0000

It’s a really nice innovative idea from Siemens to launch the new game augmented reality (AR) football game on the mobile phone for the coming world cup. At last another use of cell phone cameras other than taking up skirt pictures.

Here is a nice screen cap of the game:

MySQL is here

Harun Yayli — Tue, 25 Oct 2005 13:41:55 +0000

It’s a great day. At least for me.
The well anticipated mySQL 5.0 is out!
Go get it. Use it.

When C is the Best (Tool for the Job)

Harun Yayli — Tue, 11 Oct 2005 12:43:44 +0000

Here is a great article why C should be prefered sometimes, which I totally agree:

Portability

Open-Sourcability

Low-levelness

Self-contained-ness

Making use of UNIXisms

Integrability

Speed and Memory Consumption

New HCIs and SymphonyOS

Harun Yayli — Wed, 07 Sep 2005 13:39:23 +0000

I was reading this article about “Top 8 Reasons HCI is in its Stone Age” and one of the arguments was about the screen corners:

The irony is that we argue about whether systems should be application-centered or document-centered, probably the two most important entities in a computer. Have you ever seen a system which lets you, out-of-the-box, hit a corner in order to do anything at all even remotely related to anything having anything at all to do with a document or application? So maybe documents aren’t the most important entity in a computer. Browse the internet by hitting the screen corner? Check mail in the screen corner? Get Info in the screen corner? System preferences in the screen corner? Switching applications in the screen corner?

And this argument makes more sense after seeing SymphonyOS: a Desktop computer operating system based on Debian GNU/Linux and Knoppix GNU/Linux.

I seems some people out there is really working on human computer interfaces…
Great job. I’m impressed.

PSP Browser

Harun Yayli — Fri, 26 Aug 2005 15:32:48 +0000

The update 2.0 for PSP is out so the internet browser…

here is the headers for PSP browser…
no gzip or other encoding it seems…

A huge warning : If you want to be PSP friendly website. Don’t use upper case letters in the URL.

Update: One of the biggest questions: No it doesn’t support AJAX
and CSS is a bit problematic for the div having absolute positioning in relative divs…

Meetro

Harun Yayli — Tue, 09 Aug 2005 17:14:57 +0000

ICQ + L10n sounds like a good idea.
But the bad side of Meetro is I guess, that you have to download something.
All the functionality of Meetro would be on a website…

And what about a dating website together with functionality of Google Maps and blogging…

That would be hot!

Now both Windows Vista and IE7 is on beta…

We’ll see what will happen. I hope microsoft does not spoil RSS with IE7.
