Finally got my domain issues worked out. For long time the domain was pointing to wrong server and for many weird reasons I couldn't get it to update.

Next I'll start transfering this blog to my own server and to a new and improved platform.
Also hopefully finally get some time to actually update it also...

While ago friend of me asked for a script to detect if site is browsed with mobile device.
There are lot of these around on the net and here is my contribution to that list.

Hopefully someone else find this usefull also:

public function is_mobile($include_iphone_and_ipod=true)

{

    $mobile_browser = 0;

    $user_agent = $this->get_value('_SERVER', 'HTTP_USER_AGENT');

    

    if (preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone)/i', strtolower($user_agent))) {

        $mobile_browser++;

    }

    

    if (! $include_iphone_and_ipod) {

        if (preg_match('/(iphone|ipod)/i', strtolower($user_agent))) {

            $mobile_browser--;

        }

    }



    if (   (strpos(strtolower($this->get_value('_SERVER', 'HTTP_ACCEPT')),'application/vnd.wap.xhtml+xml')>0)

        || ((   $this->has_value('_SERVER', 'HTTP_X_WAP_PROFILE')

             || $this->has_value('_SERVER', 'HTTP_PROFILE'))))

    {

        $mobile_browser++;

    }



    $mobile_ua = strtolower(substr($user_agent, 0, 4));

    $mobile_agents = array(

        'w3c ','acs-','alav','alca','amoi','audi','avan','benq','bird','blac',

        'blaz','brew','cell','cldc','cmd-','dang','doco','eric','hipt','inno',

    );



    if (in_array($mobile_ua, $mobile_agents)) {

        $mobile_browser++;

    }

    if (   $this->has_value('_SERVER', 'ALL_HTTP')

        && strpos(strtolower($this->get_value('_SERVER', 'ALL_HTTP')), 'OperaMini') > 0)

    {

        $mobile_browser++;

    }

    

    if (strpos(strtolower($user_agent), 'windows') > 0) {

        $mobile_browser = 0;

    }



    if ($mobile_browser > 0) {

        return true;

    }



    return false;

}

As many of you might have already heard from me or various places on the net after my motorcycle accident last year
I got myself a prosthetic USB finger .

After last night when my friend Bergie blogged about this many have contacted me through email and asking if it is true or how can I work while my finger is in the USB or Is it attached straight to my bone, etc.
So I think it is best I'll try to explain some of these here now.

First of all it is not attached permanently in to my body, it is removable prosthetic which has USB memorystick inside it.

Secondly when I'm using the USB, I just leave my finger inside the slot and pick it up after I'm ready.

Currently I have Billix , CouchDBX and Ajatus installed inside it.
I'm planning to use the other prosthetic as a shell for the next version, which will have removable fingertip and RFID tag.

I hope this helps some people to better understand what this all is about.

Midgard

For quite a while Joonas and I have planned to do a Textmate bundle for Midgard CMS to fasten and ease the code development and work as a reference to the thousands of methods MidCOM and Midgard has.

Finally last night we just decided to put the project on properly and uploaded it to GitHub.
Today I added (and adding right now) quite alot of the basic methods.

Here's a screenshot of shortcuts for the Query Builder.

with these methods even complex queries can be built lightning fast. We will be adding more stuff as time goes by.

UPDATE [08/06/2008]: Version update. Did some fixing and made it work better with larger structures.

Here's another simple little helper I developed for Duct framework.
I use this one to convert my arrays to XML. As Duct automatically scaffolds objects from XML/YAML to database
and uses the same methods to render the database objects to html forms for editing I needed some quick way to
transform this data to and from XML. Class end examples are here

Usage example:

<?php

$resource = new xmlObjectItem();

$resource->items = array(

    'id' => 100,

    'name' => "Jerry Jalava",

    'person_id' => 1

);

$resource->attributes = array(

    'person_id' => array(

        'is_assoc' => true,

        'foreign_model' => 'person',

        'foreign_key' => 'id'

    )

);



$resource_set = new xmlObjectSet();

$resource_set->wrapper_id = 'resource';

$resource_set->items[] = $resource;



$projects = array();

for ($i=1; $i <= 1; $i++)

{

    $object = new xmlObjectItem();

    $object->items = array(

        'id' => $i,

        'name' => "Project {$i}",

        'manager_id' => $i+1,

        'resources' => $resource_set

    );

    

    $projects[] = $object;

}



$project_set = new xmlObjectSet();

$project_set->wrapper_id = 'project';

$project_set->items = $projects;



$clients = array();

for ($i=1; $i <= 1; $i++)

{

    $client = new xmlObjectItem();

    $client->items = array(

        'id' => $i,

        'name' => "Client {$i}",

        'contact_id' => $i+1,

        'team-leader' => null,

        'projects' => $project_set

    );    

    $client->attributes = array(

        'contact_id' => array(

            'is_assoc' => true,

            'foreign_model' => 'person',

            'foreign_key' => 'id'

        )

    );

    

    $clients[] = $client;

}

$client_set = new xmlObjectSet();

$client_set->wrapper_id = 'client';

$client_set->items = $clients;



echo "complex set:\n";

var_dump($client_set);



echo "\n--------toXml---------\n";



$xmlSet_clients = xmlObjects::toXml($client_set, 'clients');

echo "complex:\n";

echo $xmlSet_clients;



echo "\n--------fromXml---------\n";



$client_set = xmlObjects::fromXml($xmlSet_clients);

echo "client_set root: {$client_set->root}\n";

var_dump($client_set);



echo "\n--------back toXml---------\n";



$xmlSet_clients2 = xmlObjects::toXml($client_set);

echo "complex:\n";

echo $xmlSet_clients2;



if ($xmlSet_clients == $xmlSet_clients2) {

    echo "\n\nVALID SET CONVERSION\n\n";

}

While I was building Duct Frameworks server side with PHP5 I realized I needed some kind of event support for it.
So I created similar approach that ActionScript uses. You can download the class with example from here.

Hopefully this comes in handy for someone else also. 

Here is simple example also:

<?php



class mother extends events_observable

{

    public function __construct()

    {

        parent::__construct();

        

        $this->addEventListener(events_event::ONCONSTRUCT, events::delegate($this, 'on_object_constructed'));

    }

    

    public function on_object_constructed($target, $args)

    {

        echo "{$target->name} has born.";

    }

}



class child extends events_observable

{

    public $name;

    

    public function __construct($name)

    {

        parent::__construct();

        

        $this->name = $name;

        

        $this->dispatchEvent(new events_event(events_event::ONCONSTRUCT, $this));

    }

}



$mother = new mother();

$child = new child('Jack');



?>

I've planned doing this for soooo long and finally I took up the challenge and redid everything...
Later on I'm going to move to other server so I'm getting more recent Midgard beneath and some new stuff to the site.

Hope you guys like this... If you have any comments/wishes drop me an email or shout at Jaiku...

Later

Duct is something I have planned doing for a while and started coding last week.

What is Duct? (or what it will be)

Duct is a Flash framework with different generators and tools.
with single click it can generate dynamic Flash Sites, Banners, Polls, Surveys, etc. (through engines)
It has it's own server implementation also which allows dynamic content, mail and other features
for Flash. Server side is written with PHP but I have planned a Python version of it also.

Currently Duct UI is built to Flash IDE but I have plans to add Commandline, Online and Standalone support also.

I'm going to publish this as a Open Source project as soon as it gets a bit more mature.
Also more about the whole project will be published later.

Here are some screenshots of the Banner Engine. (And scaffolded banner project.)

(All these files have been generated after pressing the "Create" -button)

Today when I was leaving from home to Helsinki I decided to take a taxi from my house to the train station.
For my supprise the Riihimäki taxi operator was a bit more enhanced than I could have imagined.
This is the call I made

Machine answers: Hello, finding your position now...
[After few seconds]
Machine: Calling nearest available taxi, please wait...
Taxi driver: I will be there in two minutes.
Me: Thank you.


I could believe this in Helsinki but not in Riihimäki which is really small town...
We are going to the right direction....

Ajatus LT was accepted to this years FOSDEM in Belgium.

At this point it seems the presentation will be on Sunday 24 at 15:40.

I'll be introducing Ajatus itself and little bit about the pieces it is built on (CouchDB, jQuery).
Mostly I try to concentrate the presentation for developers interested either in offline AJAX development or even Ajatus itself.
I will be showing and explaining some of the layers inside Ajatus, different ways to expand it with plugins, etc and give sneak peak to the future of the app.
Some basic replication scenarios will be covered also.

At the same weekend Bergie and I will be attending the XMPP Devcon to collect and present our ideas of the automated XMPP based CouchDB replication currently going under name PillowTalk. 

Finally got the new release out.
This fixes some bugs and adds cool new features.

Go check it out at http://www.ajatus.info/download/ajatus_0-6-0/  

Today I got the complete stack working on my N800 device!

• Erlang
• ICU
  
• CouchDB
• Ajatus
  

They are far from perfect yet but I'm sure it'll get better little by little.
Currently I'm

• preparing the packages for releasing them through maemo extras repository.
• trying to compile the latest erlang R12.b.0 (now the package is R11.b.1)
• adding dependencies to couchdb package
• packaging Ajatus also

After first releases there are some possible tweaking to do... I still get some Segfaults at some points while using couchdb.

If someone would like to give this a try the hard way:
All the current packages can be found here http://protoblogr.net/downloads/erlang/

1. Download and install erlang-base_11.b.1-1_armel.deb to the device (after download: dpkg -i  erlang-base_11.b.1-1_armel.deb)
2. Download and install libicu36_3.6-2_armel.deb
3. Download and install couchdb_0.7.2-1_armel.deb
4. Get the latest release of Ajatus and follow it's installation instructions

There might be some dependencies which have to be manually installed. (Will be fixed later)
Currently the CouchDb installs itself to /usr and the databases are located at /usr/var/lib/couchdb.
I changed the DB path in /usr/etc/couchdb/couch.ini to point to my other memorycard (/media/mmc2/couchdb_db) which had some more space left.

Hopefully I get to release these as soon as possible for easier use.

Great thanks to the folks at #couchdb channel (nslater, jan,...)
And to Piotras

Last night I finally was able to do successful packages and installation on my N800.

First set (N800/N810) can be downloaded here: http://protoblogr.net/downloads/erlang/

I'll upload rest of the deps as I get to the office. Also I'm currently buildin ICU which is also needed by CouchDB. Hopefully today I have working native Ajatus on my N800. 

UPDATE: 

Just uploaded rest of the package files. Also there is packages for ICU.
I'm currently trying to get CouchDB to work, but still have some minor problems with it.

For basic usage of erlang one could only install the erlang-base and erlang-nox packages...

I was able to package Erlang for X86 target but collided with some segfaults on Armel. It seems the problem is the qemu and after a while trying to patch it I gave up for tonight. Have to continue tomorrow night.

Anyhow we aren't that far of getting CouchDB and Ajatus to work natively on Nokia n800/n810...

Few nights ago while I was searching for Erlang resources in the big web I came across interesting project HaXe.
After few hours of reading I was sold. I started testing with different options and had an idea for a project... CouchBrowser.

CouchBrowser is cross platform CouchDB administrating utility which runs as standalone app. User interface is built with flex for sleek looks. Backend is written with haXe and ActionScript.
So currently I'm building CouchDb library for haXe similar to my other project jqCouch.
Planned features for the CouchBrowser are atleast the same functionality as the couch's own browser based utility plus some export/import features.

I'll put up some project site for this as it matures a bit and I get more time to work with it.

Here is a screenshot of the app (v0.0.1)
