]]> New stable version (4.4), new distribution model and a video tutorial! Tue, 3 Apr 2012 12:31:00 +0100

Hi all,
DaDaBIK 4.4 final version is out! A lot of bugs have been fixed (thanks to all the guys who reported them through the forum!) and this can be considered the new stable version of DaDaBIK, which officially supports MySQL, PostgreSQL and SQLite. Since some bugs are critical and affect not only the previous release, all the users are strongly encouraged to upgrade.

As you could have noticed, I removed the official support to Oracle and MS Sql Server; the percentage of Oracle and MS SQL Sever users is very small and I prefer, for the moment, to focus my effort on the other DBMSs.

This new version also added three new features: the official support for Views management, in addition to tables (this can help a lot in creating more flexible database applications); the possibility to hide the NULL checkboxes in forms (a change which a lot of users requested) and a new language translation: Russian (thanks Eugeniy!).

As always, you can find all the changes in the changelog (http://www.dadabik.org/index.php?function=show_changelog).

Many users asked me a simple tutorial to start with DaDaBIK (in addition to the documentation) so I decided to record a video tutorial which, in less than 15 minutes, explains how to create a very basic DaDaBIK database application without coding. The video is available on Youtube (http://www.youtube.com/watch?v=uPmXoep91Vk). This is the first of a serie of episodes, please let me know your feedback!

Since I want DaDaBIK to be part of my daily Job, I also decided to change the distribution model; now a donation (or, if you prefer, a variable price) is required to download DaDaBIK. You can download DaDaBIK starting from 3 euros including VAT, less than a beer, but if you can afford it you can also pay more. A regular invoice is produced and sent.

I hope that everyone will understand this new approach, which also means a personal commitment to the development of the software, and realize that DaDaBIK actually worths much more than 3 euros. To give some examples, two other applications having similar purposes cost respectively US$159.95 and US$79.

Ciao,

Eugenio

]]> $65 discount on Web hosting for DaDaBIK users Sun, 19 Feb 2012 23:55:00 +0100 Hi all,
thanks to the rewards program of Dreamhost, I can provide a $65.00 discount for a year of Web hosting; the normal price for a year is $119.40, using the promo code DADABIK you'll pay just $54.40 if you are a new customer.

I tried several Web hosting services during my career of Web developer and it's difficult to find the perfect one; Dreamhost, as the others, isn't without defects. I don't like, for example, their marketing approach, which makes prices and features not very clear. However, it is probably the best Web hosting service I have ever tried. I am impressed by their very complete control panel, from which you can really do everything you need.

About the support, I am using Dreamhost for a project I'm working on (sharing Web hosting and VPS Mysql) and I had the chance to test it: I don't know if the service is the same for all the plans but they literally saved my life last Christmas night when, by mistake, I dropped a very important MySQL table....yes, I did it, it happens :(
After having waited some time, I managed to chat - during Christmas night - with a guy from the support and the next day they provided a backup of the table (created automatically) that let me recover almost all the data; I lost only the last 36 hours of activity. Just for this reason I think I can promote their services, something I usually don't do.

Let me know, if you try it, your impressions.

P.S. Note that sometimes Dreamhost provides other special discounts, different from the one I'm providing and that you can't combine discount with additional discount.

UPDATE: I realized that, to use the DaDaBIK promo code, you have to go directly to http://signup.dreamhost.com/; at some point, the subscription procedure will ask you for an (optional) promo code. Furthermore, you should clean dreamhost cookies if you visited the homepage before, because otherwise the system takes the current dreamhost promotion as default. Very bad, I know :(
So I advise to look at the homepage and see if there is a promotion available, check if it is better than the one I am offering (could be) and if not clean the cookies and subscribe through http://signup.dreamhost.com/ using the DADABIK promo code.

]]> DaDaBIK 4.4 beta is out! Wed, 14 Feb 2012 17:29:00 +0100 Hi all,
a new DaDaBIK version is available. Back to work on DaDaBIK after a long parenthesis during which I was mainly doing research and working on my Mentor.FM project.

Version 4.4 beta fixes several bugs (see change log for a complete list).

A new bug related to dates has also been discovered and not yet fixed; not sure if it is correct to call it bug but for sure it can lead to unexpected results, modifying the date values you have in your database. Thanks to Mauri for having reported part of the problem, please look at the known bugs section of the documentation for all the details.

The lack of a locking mechanism has also been highlighted in the documentation, since the current behaviour could lead, in some situations, to unexpected results and data loss.

About the roadmap, the idea is to release a 4.4 final after having found the best possible solution for the dates "bug" and, later, to release a 5.0 alpha which will include a new security model and also provide a locking mechanism.

Stay tuned!

Eugenio

]]> DaDaBIK roadmap and OT: the Mentor.FM project Fri, 4 Nov 2011 16:50:00 -0800 Hi folks,
thanks for your patience and sorry for the long period of silence!

The new security/permissions model of DaDaBIK has been designed and a new dedicated admin interface has been built for providing to the user an easy way to set permissions. There are users, there are groups and the system provides a fine granularity approach: for example you can disable the edit for a specific field and a specific user or group.

All this new logic needs now to be integrated into the DaDaBIK engine; I don't think this new DaDaBIK version (5.0) will be published before the new year, most probably the first months of 2012. Two intermediate versions (4.4 beta and 4.4 stable) will anyway be released before.

OT: I'm working on a research project about Music Recommendations and I published a Radio application I'm using to test some algorithms, the Mentor.FM radio. You can listen to music for FREE and without ADVERSTIMENT, according to your taste, until the end of the year. You can find further info at the page "What's mentor.fm?".

Please try Mentor.FM, I would be glad to receive your feedback! if you want, you can also like the Mentor.FM page on Facebook.

Cheers from California,

Eugenio

]]> Next releases of DaDaBIK and new security model Sun, 22 May 2011 22:32:00 -0800 Hi all,
I am glad to announce that Alessandro Andreoli, an Italian student of the University of Milan, decided to join the DaDaBIK team and to do a very important work on DaDaBIK as part of his master thesis in Computer Science.

Alessandro is working on the new DaDaBIK security model, something I wanted to implement since years but I didn't find the time to.
When his work will be finished, it will be possible to create group of users and to set permissions at a very granual level, for example saying that the group X has read permissions on the table customers while user Y has also write permission on that table, but not on the field customers.phone_number.

It is a very important shift toward the adoption of DaDaBIK in an enterprise environment.

A big "thank you!" to Alessandro from all the DaDaBIK community.

Another big news is that I'm writing from the United States, where I'm going to live for some months as a visiting scholar at UC Berkeley.

I Hope to give you some news about the next release of DaDaBIK soon!

]]> I need feedback from SQLite users Wed, 2 Mar 2011 18:44:00 +0100 Hi all,
as you probably know, DaDaBIK now supports SQLite. Since February 2 2001, more than 30 SQLite installations have been registered online.

I would like to have feedback (good and bed feedback) from those users, because I'm going to release a new version.

I also remind you that the Like, disLike & Propose Wiki will still be available for one month. Please use it to tell what you like, dislike and propose about DaDaBIK. A feature selected anong the ones proposed will be implemented.

]]> DaDaBIK has SQLite support, v. 4.4 alpha is out! Wed, 2 Feb 2011 12:58:00 +0100 Hi all,
I'm proud to announce that DaDaBIK has now SQLite support!

The SQLite database engine has become very popular in the last years and I think its support can increase the user base of DaDaBIK.

Since I experienced some problems in trying to write an ADOdb driver for SQLite3, I chose to use the PDO library instead; this means that you need at least PHP 5.1 to use DaDaBIK with SQLite.

Beyond SQLite support, you can find the complete list of new features, feature changes and fixed bugs for DaDaBIK 4.4 alpha in the change log.

Maybe it's important to point out that the SQL logging feature, due to some problems I experienced with the last ADOdb releases used since DaDaBIK 4.3 beta RC2, is not available anymore.

]]> University of Cambridge uses DaDaBIK Sat, 18 Dec 2010 20:01:00 +0100 I've read on ReadWriteWeb that the University of Cambridge used DaDaBIK for the World Oral Literature Project.

DaDaBIK is used to manage and show online a "database of language endangerment levels with references to collections and recordings of oral literature that exist in archives around the world". Here http://www.oralliterature.org/research/databaseterms.html you can see the on-line application.

]]> DaDaBIK 4.3 final release is OUT! Wed, 8 Dec 2010 23:41:00 +0100 Hi all,
I'm proud to announce the final release of DaDaBIK 4.3.

After 3 months of work, 6 intermediate releases, about 25 bugs fixed and several new features/changes, we can provide a final release.

I hope this could be a milestone in the DaDaBIK development process.

In this release the main changes are the upgrade to TinyMCE 3.3.9.2 (this can fix security problems and other issues that the old TinyMCE version used could cause), the fix of the extracting problems with some MS Windows systems and the fix of some delete-all related bugs. The complete list of the changes are available in the changelog. The on-line changelog for some reasons didn't contain the changes for DaDaBIK 4.3 beta 3, this was fixed too.

I have added a small Amazon link to the Amazon mp3 store in the admin interface. If you buy mp3s from that link (can be a nice XMASS gift!) you can financially support DaDaBIK. If you don't like it, DaDaBIK it's open source so you can delete it.

]]> DaDaBIK 4.3 rc2 is out Sun, 28 Nov 2010 18:25:00 +0100 Hi all,
the main change is the upgrade of the ADOdb library.
Some users (thanks Chris) reported that DaDaBIK, with some PHP versions and error reporting settings, produced some "Deprecated" and "Strict Standard" warnings. This was due to the ADOdb version used, which was too old. DaDaBIK now uses the last ADOdb version for PHP5 and automatically load the last PHP4 compatible ADOdb library if you are still using PHP4. This can also fix security problems and other issues that the old ADOdb version used could cause.

Another improvement regards DaDaBIK code's footprint: a lot of not strictly-needed files has been removed from the official release, which is now lighter (zip file less than 2MB).

Finally, the single-donation button of the admin section now works as expected.

For the complete list of changes, read the change log

]]> 4.3 rc1 is out, new admin section, last security patch, PLEASE UPGRADE! Tue, 23 Nov 2010 11:41:00 +0100 Hi all,
the version 4.3 release candidate 1 is out; I think it's a milestone in the DaDaBIK road map: many bugs fixed and a new admin section. I hope the 4.3 final release will be available soon, but the idea is to come out with something that can produce applications very close to the enterprise level quality without coding so I want to wait your feedback on this rc1.

From the security side, DaDaBIK 4.3 beta3 in a case-sensitive environment didn't include the htmLawed library; this left DaDaBIK exposed to the security risk that version 4.3 beta3 was supposed to fix; now the problem is solved and also another (potential) security problem has been fixed as you can see from the changelog (where you can find the complete list of changes and bug fixes related to the version 4.3 rc1). So you really need to upgrade!

Teh new admin section, a lot of work: new look, some improvements in the interface, in-line help for the interface configurator, possibility to send feedback, to donate and to buy email/phone commercial support. The configuration file has been improved in clarity too.
Furthermore, the documentation has been completely revised, clarifying some aspects when needed and highlighting some new known bugs/limitations.

A completely new demo is also available, it's an enterprise-oriented application: a simplified invoicing system.

Donations: I'm very happy to see that, just during the last 15 days, 33 people decided to give some money to the project. But it's stil a very small fraction of all the people who download DaDaBIK (a lot) and it's not enough to dedicate a fixed amount of time to the project like I'm doing at the moment. Please have a look to other commercial softwares similar to DaDaBIK, then come back here and think if it's fair or not to donate some euros if you use DaDaBIK, considering the plus of having the source code available.

My road map (an update soon in the section) is quite clear now: a couple of 4.x which fill fix some bugs and/or introduce some small new features and try to enlarge the users base introducing the support for SQLite, IBM DB2 and (maybe) Microsoft Access, then (in 6/7 months) a version 5.0 which will come out with (maybe) some code refactoring but first of all with a completely new security/permission infrastructure with high granularity: the possibility to allow the user John to see just some fields of a table for example.
In order to follow the road map I need to be economically supported , this is the way to allow DaDaBIK to survive. If a compamy would like to sponsor the development of some new features (according to the company's and the project needs), it would also be very welcome.

]]> Security Risk, second patch. PLEASE UPGRADE! Mon, 15 Nov 2010 12:42:00 +0100 Hi all,
a new beta version (DaDaBIK 4.3 beta3) has been released in order to solve the second problem I post about a few days ago, the one related to the use of the html content type. First of all it is better to highlight that the problem could arise not only with the html content type but also with the rich_editor field type (together with another content type than html); I think the rich_editor is usually used together with the html content type (it should be) but maybe someone used this in conjunction with other content types.

After having looked at some HTML sanitization libraries, I finally choosed htmLawed. It seems to me that at the moment htmlpurifier is the most effective one in recognizing malicious code, but it appears to me too complex, heavy and it also doesn't support PHP 4. htmLawed seems a good compromise.

The library is now used to filter the content (html content type and rich_editor field type) before displaying it. You must however keep in mind that, as the documentation states, there are some minor cases in which htmLawed can fail.
Since some people asked me about previous releases, as I already told in a comment, the security issues highlighted during the last days also affect the older releases of DaDaBIK and not just the last one.

See the changelog for other details. The documentation has also been updated; if you have read the on-line documentation this morning there was a mistake about the version was related to: the documentation content was the new one (related to 4.3 beta3, already patched with htmLawed) but it stated to be about the 4.3 beta2 (which is not patched with htmLawed) so be sure to read the right one (the on-line mistake has now been corrected) in order to avoid misunderstandings about the security problems that affect your version.

]]> Security Risk, PLEASE UPGRADE! Thu, 11 Nov 2010 15:31:00 +0100 Hi all,
last night I discovered an important security hole in DaDaBIK so I decided to immediately release a version 4.3 beta2 with the only purpose of partially fixing it. All the other bug fixes and new features are waiting for the version 4.3 rc1, avaiable in 1 or 2 weeks as expected.

Here is the problem: if in a DaDaBIK application the insert or edit feature was enabled (at least for one table) and a select_single field type was used (at least once, even in another table), a malicious user who had access to the application could in many cases insert in a listbox some arbitrary javascript code, which was then executed by other users just by using the application.
Among other problems, this could lead to XSS attack (http://en.wikipedia.org/wiki/Cross-site_scripting), which in turn could allow an unauthorized access to the application (http://en.wikipedia.org/wiki/Session_hijacking) and, if the Internet browser of the user contained security holes, even the execution of arbitrary code in the client machine.

The new 4.3 beta2 solves this problem. Even the DaDaBIK demo was affected and exploited by a malicious user; now it has been patched.

The problems described above can however occur even when the insert or edit feature was enabled (at least for one table) and the HTML content type is used; at the moment there isn't a patch for this second scenario, so the HTML content type should be used very carefully, as highlighted in the upgraded documentation. In the next few days, I would like to use something like http://htmlpurifier.org to allow the users to insert html text without security problems.

The 4.3 beta2 also fixes another minor GUI bug, as you can read from the changelog.

]]> Is DaDaBIK still used with non-MySQL DBMSs? Tue, 09 Nov 2010 01:56:00 +0100 Starting with the last 4.3 beta, the users can register the installation of DaDaBIK; I receive information about DBMS type and DaDaBIK version.
97 installations have been registered so far and these are the statistics about the DBMSs usage:
MySQL: 95 installations
PostgreSQL: 2 installations
Oracle: 0 installations
MS SQL Server: 0 installations

97 is (statistically) still a small number but I'm wondering if DaDaBIK is still used with non-MySQL DBMSs....maybe the tipical Oracle or MS SQL Server user doesn't work much with PHP but I think that it's not true for a PostgreSQL user.

I decided to dedicate some time in future to test DaDaBIK with other DBMSs (SQLite and DB2) but if everybody's using MySQL I don't know if it's still a good idea.

]]> New admin section, new release soon Thu, 28 Oct 2010 12:38:00 +0100 Hi,
I have finished the redesign of the admin section: new look, some improvement in the interface, in-line help for the interface configurator.

This will be released soon with DaDaBIK 4.3 release candidate 1, together with an improved documentation and a new enterprise-oriented demo (an invoicing system) that I'm developing.

]]> 4.3 beta is out, we have a (hopefully) cool graphic interface! Thu, 21 Oct 2010 02:07:00 +0100 Hi folks,
yes, difficult to believe but true!
DaDaBIK is powerful and easy to use but the GUI has always been something that could hurt....
Why? Because I'm too nerdy to take care about GUIs? No, just because having limited time I've always preferred to spend it improving the features set and fixing bugs.

But your long wait is over, some days ago I discovered by chance a very nice DaDaBIK graphic customization made by Erik Pöher; I firstly started to implement that GUI but I ended up developing the GUI from scratch, in part inspired by Erik's work. Here is the result: demo (user: demo1; password: password).
There is still space for improvement (better warning/error messages for example) but I think it's much better than before. Let me know what you think.

Another important improvement: magic_quotes_gpc set to On is not anymore needed.

There are also several bugfixes, as you can see from the changelog; some new bugs were also dscovered.

]]> We have a new forum! Sun, 17 Oct 2010 23:57:00 +0100 Hi,
a new forum is available! I finally decided to continue using phorum (www.phorum.org) as software, mainly for two reasons:
- they provide a script to convert my old forum data
- even if it doesn't provide all the features that some competitors do, it focuses on reliability, simplicity and customization and for this reason I feel it very close to the DaDaBIK philosophy. They also have an amazing support.

All the old user accounts are still valid. You have now some of the modern forum features, including avatars, private messages and so on...

I still need to embed the forum into the Web site layout and find a solution for a problem: in many posts there are links to other posts, but those links don't work anymore because phorum 5 uses a different way to call a post via URL.

Anyway, enjoy it and let me know problems/bugs!

]]> Update on donation campaign & new release soon Mon, 4 Oct 2010 00:56:00 +0100 Hi folks,

I have to spend a couple of words talking about the donation campaign: since I posted my appeal to donate in order to allow the project to continue (more or less three weeks ago) I received 18 donations.

I am very happy about your answer. Really.

Several donations are small but no problem, I think that the act of donating is still very important regardless of the amount. The "donation economy" is something that could really change the way software (and other things) is created and distributed and we should really get used to try it (both passively and actively) to understand if it can work.

Here is the list of our heroes (not complete, I haven't got all the permissions to publish)!!:

Rüdiger Fritsch
Richard Bradbury
Yiannis Vavouranakis
Roberto Javega
William Armstrong
Robert Bacchas
Patrick Simon
James Merrihew
David H.
Michael Frotscher
Jason Fifner
HISPANIC SEARCHING S.L.

Many many thanks guys!

I also want to tell a big "thank you" to RHX, the italian software and hosting company that since many years ago is providing Web hosting and domains to DaDaBIK for FREE. These guys strongly believe in Open Source software and they demonstrate it with facts.

Ok, second thing: a new release of DaDaBIK will be available soon, together with a new Graphical User Interface! :-)

Very last point: DaDaBIK is now on Twitter: http://twitter.com/DaDaBIK I still don't know if I will use it just as a reminder for the posts published in the main site or for something different, anyway…follow us! :)

]]> DaDaBIK 4.3 alpha is out. Master/details view: done! Tue, 14 Sep 2010 04:12:00 +0100 Hi,
A new DaDaBIK release is out, together with a big new feature: the master/details view, that allows to easy handle a typical One-to-Many relationship.

For example if you have an albums table and a songs table you can set DaDaBIK to display in the same page the details of an album and the result list of the songs linked to. Here is an example directly from the updated DaDaBIK demo: http://www.dadabik.org/demo/index.php?table_name=albums_tab&function=edit&where_field=ID_album&where_value=1

It is also possible to link more than one details table to the same master.

I set up a donate+download button and I encourage you to use it, it is the only way to allow the further development of DaDaBIK!

Check the change log for the complete list of changes.

Cheers,

Eugenio.

]]> DaDaBIK is ALIVE and need your support! Tue, 09 Sep 2010 23:43:00 +0100 Hi folks,
yes, I know, long time since the last post and almost three years since the last DaDaBIK release :(

I haven't had enough time for DaDaBIK in the last period and, to be honest, I also haven't had enough reasons to spend my nights and my spare time in coding and testing as I did before.

It's hard to believe but the next year DaDaBIK will turn ten. Ten years! First public release on Sourceforge: November 2001. I can't imagine how many bugs that version contained :))

Many many times during this “sabbathic” period I tried to decide something about the future of DaDaBIK but I didn't manage to do it.
But...after nine years from the first release, almost three years from the last release and more than two years of “silence” I still get e-mail from people who want to thank me, people still download DaDaBIK, people still write on the forum, people still use DaDaBIK: http://www.google.com/search?hl=en&ie=UTF-8&oe=UTF-8&q=%22powered+by%3A+dadabik%22&btnG=Google+Search
so now I'm sure that DaDaBIK is not dead and I WANT TO KEEP IT ALIVE because maybe was one of the most useful things I made.

I used to work as a consultant for a software house but some months ago I decided to quit my job and to dedicate the next year almost entirely to scientific research: I'm doing a PhD on recommender systems (http://en.wikipedia.org/wiki/Recommender_system) and I have to work hard on it now; I won't have so much spare time but I really want to take some time for DaDaBIK...even because I really need some coding activity :)
But this time I really need your support; DaDaBIK is still a GPL software but, after hundreds of hours spent on it for free, now I really would like to have some economic return for the future work. If you think DaDaBIK is useful, I ask you to donate some money to the project; even a few euros/dollars is enough if a lot of people will do it. If you also use DaDaBIK for your business and make money with it, you should perceive the donation as the MOST NORMAL THING TO DO.

Chris Anderson predicted that "free is the future of business"; I instead hope the future will be: users paying small fees (would be great if voluntarily) for good services/software, and I want to experiment this with DaDaBIK.

I still don't know if I will implement a real business model for DaDaBIK, by now I would like to put more emphasis on free donations and see what happens, see if the community will respond to my appeal; then maybe I will try a more structured approach (see for example how the ardour project gets money http://ardour.org/development) or a donation-per-feature approach. I also thought about double licensing and selling a commercial version of DaDaBIK, what do you think? Will someone be interested in paying for a commercial/premium version of DaDaBIK? DON'T WORRY, my ideas is too always keep a GPL version available.

I don't know exactly where to start; the code is a bit old-fashion now but it's clean and it works so for the moment I think it wouldn't be so useful to rewrite DaDaBIK from scratch using some modern paradigm. Maybe it would be better to start implementing the next steps of the road map or including some of the custom features that users added to DaDaBIK during these years.
The Web site too would need an update, but maybe at the moment just for the fourm: the forum system (phorum) is very old and now there are many open source systems with a lot of interesting features like the trust level of each user. What do you thing about this? Any suggestions? I think the second issue in order of importance would be adding a real blog system to the site instead of this home-made announcement system.

Last but not least: I (we) really have to say a big “thank you!” to Debbie, who during these years took care of the support forum, even during my virtual absence. Debbie YOU ARE GREAT!

Ok, long post but many things to say after so long time. Now I would like to read your comment, please let me know what you think.

Ciao,


Eugenio

]]> Web site problems solved Tue, 28 Jul 2008 23:28:00 +0100 Hi all,
during the last three weeks this Web site has experienced some problems in sending e-mails. The problems have been solved.

About the Forum issues (PHP5 compatibility) you probably noticed (I didn't post about this) that I solved them some time ago, without upgrading Phorum; the only problem is an annoying error message that you can see viewing a post detail without being logged-in (e.g. http://www.dadabik.org/forum/read.php?f=1&i=10323&t=10323) but the forum is totally usable.

I want to thank Rainer Scheidegger for this, who pointed me out a very simple solution.

Bye,

Eugenio.

]]> Forum problems Wed, 23 Apr 2008 19:02:00 +0100 Hi all,
my ISP has unexpectately changed the PHP version of the server which hosts dadabik.org from 4 to 5. Unfortunately the DaDaBIK forum, based on an old version of Phorum, doesn't work on PHP 5.

I have scheduled for the next week an upgrade of my Phorum installation to the last version so the forum will work again!

Sorry for the inconvenience.

Bye,

Eugenio.

]]> DaDaBIK OWL Module Sun, 04 Nov 2007 14:36 +0100 Hi all,
I have developed an additional module for DaDaBIK which allows to generate an OWL ontology starting from the database managed; this is the result of my computer science degree thesis.

At the moment I have just uploaded a zip file containing three files: install.php, footer.php and generate_owl_ontology.php. If you want to try this new module, you can download it and, starting from the last development version of DaDaBIK update the install.php and footer.php files and put the generate_owl_ontology.php in the root folder.
You also need to download and import an SQL version of Wordnet from http://www.androidtech.com/html/wordnet-mysql-20.php and to edit the $wordnet_server_* parameters in generate_owl_ontology.php.

Only MySQL is supported at the moment.

I hope I will integrate the module in the development version and write some documentation soon.

Bye,

Eugenio.

]]> The forums are now working fine! Mon, 3 Sep 2007 16:26:00 +0100 Hi all,
all the forum features which need an e-mail sending (registration, generation of a new password, reply e-mail notification) didn't work correctly due to the lack of a setting required by my ISP; the good news is that now everything works!

Sorry for the inconvenience.

Bye,

]]> DaDaBIK 4.2 final released Thu, 18 Feb 2007 17:54:00 +0100 Hi all,
version 4.2 final is now available, the only difference with the previous version (4.2 beta) is that the Rumanian language is now complete.

In a few days I think I'm going to release version 4.3 alpha, which will support the master-detail view.

I think that for version 5.0 the DaDaBIK code will be in part re-written; even the data structure will change, allowing to have a DaDaBIK db, containing DaDaBIK meta data, separated from the DB(s) you want to manage.

If you have any advices about please discuss them by commenting this post.

Bye,



Eugenio.

]]> Version 4.2 beta released Thu, 8 Feb 2007 23:22:00 +0100 Hi all,
NULL values are an important aspect of the relational model so I decided not to wait for the 5.x release and to add this feature in this 4.2 beta version. Now DaDaBIK can handle NULL values.

Another feature implemented in this release is the new "is empty" search operator.

Check the change log for the complete list of changes.

Eugenio.

]]> Version 4.1 released, Web Design Contest Fri, 19 Jan 2007 10:07:00 +0100 Hi all,
after almost three months of public beta testing, more than 4000 downloads and several bugs fixed I'm proud to announce the final version of the 4.1 release of DaDaBIK.

This version fixes some minor bugs; check the change log for the complete list of changes.

Thanks to all people who daily post bug reports on the support forum.

Some people experienced problems using DaDaBIK on MySQL 5 with STRICT_TRANS_TABLES enabled; I was not able to replicate the problem, if you have any clues please report them on the support forum.

Regarding my last call for developers, two people wrote me in order to start the collaboration so I hope DaDaBIK will have a new administration interface soon.

Now I'm asking for WEB DESIGNERS: DaDaBIK needs a new, usable and cool interface; send me your proposals: two simple HTML page (one for the record results view and one for the record details view) are OK; the best one will be the new standard DaDaBIK interface. The contest will close on March 31, 2007; more about the rules of the game in the next few days.

For the winner will be a good chance to spread his name on the Web, through this popular piece of software.

Bye,

Eugenio.

]]> New release Sun, 14 Jan 2007 20:04:00 +0100 Hi all,
DaDaBIK version 4.1 rc2 produced a "[08] Error: during query execution." error message during the installation so I have fixed the bug and published a new version, 4.1 rc3.

Bye,

Eugenio

]]> New release, call for developers, RSS feed available Sun, 14 Jan 2007 19:07:00 +0100 Hi all,
a new version of DaDaBIK (4.1 release candidate 2) is available.
This version fixes some bugs, in particular the "Refresh installation" bug and the one about previous and next record links, which didn't work correctly.

Check the change log for the complete list of changes.

Call for developers: I'm looking for someone who wants to join the staff; the goal is the restyling (in terms of layout and features) of the admin section of DaDaBIK, in order to increase usability. I have realised that the admin section needs an update in order to be really usable; to work on this code you don't need to know how the DaDaBIK engine works, it is a very simple programming task. If you are interested, please contact me (eugenio dot tacchini at unicatt dot it).

An RSS feed of this "What's new?" section should be available in a few minutes.

Bye,

Eugenio]]>
