Google Gears makes me wonder 2007-05-31 04:20:53 Today I read a lot about the new “GoogleGears
” project. And it makes
me wonder
what google is doing here. Google Gears is a mix of a runtime-environment and an API to develop applications that run online as well as offline.
At a first impression it reminds me for old battles like with “Lotus Notes” where one could synchronize online and offline data. Simple for EMails but horrible for i.e. documents and complicated database content.
So why is google joining this business? My only explanation is, that they want to support their online application market (like their google-docs and picassa) by adding strong offline and synchronization capabilities. Making web applications run offline in a browser is one more step away from a single-user desktop PC - and from the OS needed here.
With their runtime-environment, google adds like an apache, and a mySQL Server to your PC. To synchronize the data on your local PC with your host system, google suggest a online synchroni

MIMEMailPHP4 FAQ : Invalid argument supplied for foreach 2007-05-13 10:26:05 Invalid argument supplied for foreach in line 364
This is a PHP warning from MIMEMailPHP4 V2.1 when you try to attach a binary file and the given file is not found or not readable. Use the getLastErrorCode funtion after addBinaryFileAsAttachment() to catch and handle that error in your code before sending the mail.
You can also gracefully ignore that warning.

MIMEMailPHP4 FAQ : using $mail->send(true); doesnt send anything 2007-05-13 07:35:05 In the examples of the zip packages the “send” method is called with parameter ‘true’. Sorry, this is misleading, the parameter’s name is “debug”. And if you set it to “true” you will just get the MIME code for the message, it will not be send.
Use $mail->send(); or $mail->send(false); to really send the message!

Programming in D - getting startet 2007-06-03 07:06:51 I am programming in C/C++ for more then 15 years now. I took a look at JAVA, programmed some applications for 5 years now. But I am not so enthusiastic with JAVA, I find it kind of childish - it never stepped out of that web application area (in my opinion). No question, JAVA is bad for system programming - and no question too, there are some better choices today for business legacy system than JAVA.
I think the programming world is moving to the component side (away from the one-for-all approach, but independent from the infrastructure system for now). So what I looked for is a modern language to program fast, system-near components. And I found D.
If you search for information D is a terrible name
Try “D” in google and you will get some billions of results. Too bad, we need a web-catalog for this topic, but start with wikipedia for a first try. You will find that …
D is imperative, object-oriented, and metaprogramming
In short, that means that D knows objects and t Read more:Programming

Multithreaded programming in D 2007-06-08 04:39:25 While in C++ there was no build-in threading support, D comes with a JAVA-like class “Thread”. So while in C/C++ you had to mingle around with threading libs like pthread or solaris-threads, in D you can leave that problem to phobos.
A simple example shows all the simplicity:
import std.c.time;
import std.stdio;
import std.thread;
int runThread(void *ptr)
{
printf("Thread %d startedn", cast(int)ptr);
sleep(10);
printf("Thread %d endedn", cast(int)ptr);
return 0;
}
int main()
{
Thread t1 = new Thread(&runThread, cast(void *)1);
t1.start();
sleep(2);
Thread t2 = new Thread(&runThread, cast(void *)2);
t2.start();
while ((t1.getState() == std.thread.Thread.TS.RUNNING)
|| (t2.getState() == std.thread.Thread.TS.RUNNING))
Thread.yield ();
printf("program readyn");
return 0;
}
That’s it. Save the code as ThreadTest.d, than compile with “gdc ThreadTest.d” and run a.out (or a.exe). What you get as output should
Yahoo! at a loose end 2007-06-07 01:06:35 About the new Yahoo
! Panama API.
When I read the interview with Yahoo!’s Dan Broberg, Managing Director of Sales Technology on Alan’s Blog, I got a feeling that yahoo!’s running after Google.
For “advanced” support, we are not charging all that much, $2000 per month. This level provides our partners with more support, more dedicated Yahoo engineering resources should they need support. At the advanced and elite levels, we’ll make specific commitments regarding uptime, and provide our partners with in our product roadmap process.
They sell support for using their API - that’s not a 2.0 approach! That’s old IT business. A 2.0 approach would be to have a FAQ + a forum + a wiki + a developer blog - and all of that for free.
APRK: Google has taken a different approach. They don’t charge for support, but rather charge a nominal fee for each API action, 25c per thousand API tokens.
DB: We’re interested in best serving our advertisers, and we different
New bugfix release V 2.1.2 of MIMEMailxPHP4_V2 2007-06-13 02:19:44 A new bugfix release concerning compatibility. There was an issue, that inline html images (CID images) were not shown correctly in the thunderbird email client. This was caused by a wrong (but accepted by MS Outlook) MIME type in the MIME mixed-boundary.
Changed the multipart/mixed to multipart/related - now it works in all mail clients.
The BUG and FIX was reported by H. Borns. Thanks a lot!

My First Drupal Site 2007-07-09 03:49:36 Yesterday I launched my first Drupal
project in alpha state.
It’s a project for a customer in the real-estate business and I selected Drupal as CMS because of it’s very well selection of extension modules and - sure - for it’s perfect team editing features.
Drupal is, like Plone, in the leading Tools area for high-end websites with dynamic content. A key-strength for my purpose was it’s possibility to assign different roles to editors with different tasks. So I can keep the power about i.e. the menu-structure but let a story writer do the business content.
Above these business reasons, I am glad to have my first PHP5 and MySQL 5 project now. All other projects I’m currently running are based on PHP4 and MySQL 4, so I hope to make new (good) experiences with this new versions. I have waited very long for triggers in MySQL - needed to do some projects in Oracle, just because of the availability of triggers. And I have heard a lot about the processing speed i Read more:First
Related Entries Plugin with WP 2.2 2007-07-18 06:31:59 When I tried to install WASABI’s nice related entries plugin on my new Wordpress site geekland it failed with the following error:
#1214 - The used table type doesn’t support FULLTEXT indexes
I am not sure if this is WP2.2 related - in the schema creation source I found no difference to 2.1 in the posts table - but I never had that problem with 2.1.
The solution is to convert the wp_posts table to ISAM (MyISAM) by issuing
ALTER TABLE `wp_posts` ENGINE = MYISAM
and after that re-issue the installation script of WASABI what does not more than:
alter table wp_posts add fulltext post_related (post_name, post_content)
Well, on my development system, the WP2.2 database was created in InnoDB format. and InnoDB does not support fulltext-search columns.
That’s all. Read more:Plugin
Espresso Machine for Take-Away 2007-07-31 09:06:36 My current favorite is a mini espresso (Italian coffee) machine. It comes with a typical can and a build in electro oven. It’s about 15 cm x 15 cm with 25 cm height and has everything to breed the Italian kind of coffee.
It is able to cook the coffee and keep it warm (not to long - or else it’s getting a bitter taste), so everything I need for long programming nights
The manufacturer is called “Splendida”. Read more:Espresso

Running tons of development servers on one linux host 2007-08-05 12:22:49 I drive about 25 domains with different technologies like wordpress, drupal, b2evolution, lussumo vanilla, phpCMS etc. Most of that need a typical LAMP. That is a Linux, an Apache, a MySQL and a PHP. It’s common sense to have kind of test systems, systems where you can test your development work before bringing it up to production. For that I use one linux machine running OpenSuSE Linux 10.2 (basically some partitions on my laptop I use with a boot manager).
Goals of the development and testing environment
There are several goal to be met by my dev-env:
Having production-near environment (Tools, Versions, OS)
Having same code for testing as in production
Having production-like network structure
Having a permanent installation
How to setup lot’s of virtual servers
on the development host
My first and most important hint: Don’t use yast2 for setting up the virtual apache hosts. That module is still buggy. Use it only to set up apache the first time.

Started New Drupal Project 2007-08-29 14:00:55 I’ve started a new Drupal
project in the DAX Investment business. It’s kind of “pre-alpha” but it’s already a very interesting project from a technology view. It will contain blocks with high dynamical image content as well as stock quotes. So I will need to look somewhat deeper to caching technology and AJAX.
It will also contain community features like blogs and a forum, so there’s also lot of work to do with taxonomy.
I’ll keep you informed. Read more:Project

Drupal localization and string adjustment 2007-09-17 09:27:27 Sometimes when setting up a drupal site, the situation appears, that I need a “special translation” for a standard module. I.e. I need a blogging functionality - but I don’t want to call the system a “blog”.
That’s when I need a customized translation of the blogging module. This article is about how to customize drupal strings with the localization feature.
Find the strings to translate
What you need first the the GNU gettext package (it’s contained in every linux distro). From this package you need the program “xgettext”. This program is able to extract the strings from the module code that can be translated (if the module is programed very well, this should be all strings in the code).
Now go the the module’s location (usualy /modules/blog) and type:
xgettext.exe --keyword=t -L PHP blog.module
The L tells xgettext, that this code is PHP code, the keyword tells xgettext, that function “t()” is used for gettext tr Read more:adjustment

Offering professional Drupal service 2007-10-06 04:27:34 After some months work with the fabulous Drupal
system I have decided to offer professional
services for that CMS in Germany. Based on Drupal 5.x I have created four websites last months, one for a community in the real estate business, one for stock investors and two company sites.
I am really good in techniques like hooks, callbacks, templates and modularization from my business experience of the last years with C, C++, JAVA, PHP … on Unix and Windows. So it was pretty easy to get deep into Drupal (also thanks to my experiences with Wordpress and b2evolution as CMS’s). Drupal is fantastic.
Certainly, I will contribute my results (as far as allowed by my customers) back to the Drupal community as open source - and, if requested, I am willing to donate time and work to a German or international Drupal project. And to support the Drupal association with money, I will donate 5% of each Drupal related turnover (must check this against German tax laws first, probably I will ha
New Drupal company site on air 2007-11-13 01:33:43 Last weeks I was working on a new Drupal
driven company
site. This time I wanted to create my theme from scratch (calles “ANewCompany”) and wanted to use heavy taxonomy for cross linking.
The site is on air now and promises professional web2.0 programming (German).
On the site I use following modules:
Blog, Book, Forum, Poll - for content creation
Comment, Contact - for visitor interaction
Drupal - for site registry
Locale - for string translation and adjustment
Menu, Path - for site navigation
Taxonomy - for cross linking and navigation
Search - for site wide full text search
Statistics - for access statistics
Akismet - for spam protection
Comment mail - for admin notifications
Service links - for social network linking
TinyMCE - as wysiwyg editor
Views - for some data mining and block representation
Fivestar, Voting API - for content voting
I developed a new page.tpl.php template where I’ve foreseen the regions as follows
function ANewCompany_regions() {
