Ajatus LightingTalk in AOP

Mon, 03 Mar 2008 19:23:01 +0000

Next saturday there is a FOSS event "Avoimien Ohjelmien Päivä" in Turku, Finland.
I will be holding a LightningTalk of Ajatus there somewhere after 3pm.

If you are coming there, let's go for a beer etc. and discuss the topic or offtopic...

Ajatus Lightning talk @ FOSDEM

Fri, 08 Feb 2008 21:14:01 +0000

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.

Ajatus 0.6.0 released

Wed, 30 Jan 2008 18:04:31 +0000

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/

Finally got them working

Wed, 23 Jan 2008 19:35:49 +0000

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/

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)
Download and install libicu36_3.6-2_armel.deb
Download and install couchdb_0.7.2-1_armel.deb
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

Packaging Erlang for maemo

Sun, 20 Jan 2008 23:16:36 +0000

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...

Revision navigation to object view

Yesterday I finished adding the metadata and revision navigation to object view in Ajatus . Now one is able to browse through the available revisions of a object and edit any of these.

New release of the jqCouch library

Tue, 04 Dec 2007 18:57:19 +0000

I'm happy to announce the release of totally rewritten jqCouch -library. Major changes were made so this version is no longer compatible with the older release. Talking with CouchDB is now done through 3 type of connections.

db -connection:
This is used to handle all those Database related tasks such as creating and deleting.
Available methods:

exists
info
create
del
all
restart

doc -connection:
This is used to handle all those Document related tasks. Creating, Updating, Deleting documents.
Available methods:

get
all
save
bulk_save
del
(post)
(put)

view -connection:
This handles all actions related to Views.
Available methods:

exists
info
get
save
del
temp
(put)

All result methods (methods that return something from the database) return their results through wrapper which can be extended with own custom method. This can be used to render the results to something else or execute other actions as soon as the query is ready. One can register this mapping method globally, for connection or for each method separately.

Some basic usage examples:

creating connections:

//Database connection
var dbc = $.jqCouch.connection('db');
//Document connection with custom config
var dc = $.jqCouch.connection('doc', {cache:true});
//View connection with connection specific mapping function
var vc = $.jqCouch.connection('view', function(data){return data;});
//Database connection with connection specific mapping function and custom settings
var dbc = $.jqCouch.connection('db', function(data){return data;}, {cache:true});

Setting global configurations:

$.jqCouch.set_defaults({
    cache: true
});

Creating new document (One liner):

var revision = $.jqCouch.connection('doc').save('doc_db', {id: "0", title: 'test'})._rev;

More info can be found from the source of the library and the testsuite included in the release This library is part of the Ajatus - Distributed CRM

For some reason the jQuery website is not working properly and it seem that it has reverted to some old backup as the release no longer exists there. Here is a local link to the release: jqcouch-2.0.1.zip

Add field -support for Ajatus

Thu, 29 Nov 2007 07:18:15 +0000

Finished the basic level of field adding.

Just finished the first step in the "Add field" -support in Ajatus today.
Next step is to add editing and deleting to the added fields.
I have also planned a template support to the fields so one can save the added fields as template and reuse that.

Yesterday we published ajatus.info

Thu, 15 Nov 2007 09:48:19 +0000

Yesterday was a big day for Ajatus - The Distributed CMS as it got its site up and running.
Read more from Bergie's blog.

I'll soon start writing some highlights that the system keeps inside...
