4th Release Candidate

Filed under: Develop — Tags: , — Malte @ 2:36 PM

Dear DeepaMehta Friends,
from upon now you can download the 4th Release Candidate of DeepaMehta 2.0b8.

New in this round:

  • Grave Bug fixed: On input of special chars (‘ and ) the HSQL-based alternative don`t crashes the database content anymore
  • Grave Bug fixed: The MySql based alternative installs properly on windows machine

We are very happy to have all of you helping us getting this release done and we would also be very happy if you want to give it another try on os x and windows with a new test installaton in the various configurations.

Thanks for the Bug Reports and thanks for fixing these issues to Enrico Schnepel.

Another Thank You! goes out to Vincent and Matthias for their contributions to the new wiki. I nearly can `t follow all the changes ;) but that `s cause of a great party weekend for my 25th.

Cheers Malte.

HowTo Update an existing Release Candidate of DeepaMehta?

You just need to extract the release candidate and take the .jar-files out of the install/client/ and install/server directory, 4 at their number. Then Copy them into your DeepaMehta installation directory into the same folders were you took them from (resp. install/client and install/server). Maybe a restart of your Java Runtime Environment would be the most securest way. Yesterday we experienced problems with expanding the provided package on a os 10.5 with StuffIt but it worked out via the terminal, please do so  too if you are experiencing some difficulties while extracting.

Have fun ;)

on fridays, coordination is coming

Filed under: Common — Tags: , , , , — Malte @ 1:52 AM

I am really looking forward to provide you some support with my skills as an application developer in the future and i will start with some deepamehta administration docs, which you can find here.

In the re:publika community meeting three ideas came up on our desk, which are interesting for me cause i think we could manage them very soon, possible in may.

1) Implement in xtreme-pogramming style an laTex-Topic (8.May)
2) Get the Screencasts started (8.May)
3) Organize the next get togther (whenever someone has some time)

Additionally, Joerg and me have planned to meet every Friday at Lunch Time for talking about current topics of interests in the deepamehta community. We just started to go into a huddle again, i had some lazy days in holiday and we both don`t want to loose weeks by weeks while working on other topics. So as a warm up session for further coordination meetings we made a info graphic, yet only in german, about possible “dances” between DeepaMehta and the World Wide Web. Not the most urgent thing now, i know, but we liked the idea of having one ;)

DeepaMehta and the WWW

Vincent was also present on Friday and we could engage him to spend some time on a possible new deepamehta corporate media-wiki. We want to build an open howTo section and sooner or later somekind of central resource for content around the deepamehta world and would be also very happy to find some users who can help us. This urgent need came up, cause i don`t have that much power to write the most basic things more than once, for example if problems with the usage come up.
We have already some good resources but most of the new demo users i attended over the last 9 month (nearly 300 new users) had the same starting problems. In the last year in July i started to work through all forum messages, there are some good hints and tips allready collected which emerged through first hand experience. it would be nice to rewrite those who i haven`t got yet and those who are useful and give them a simple structure. i managed half the messages yet.

here is an approach, which is horrable formatted yet but open for collaboration

if we have the new server ;) hopefully during the start of the week, **yippie**. we could start with a new unrestricted access media wiki and deliver a new powerful deepamehta server. it would be also great to bundle some efforts and use these possibilities for development. but small steps and one after another.

update from monday

we now have a new server and i am currently working to get a new deepamehta wiki on. if anyone wants to develop java-web-apps with the deepamehta framework, get in touch with us, but at the moment we do everything in our spare-time, so please be a bit patient.

Improved Demos

Filed under: Common — Tags: — Malte @ 5:41 PM

Since the last refreshment on our demoserver it is now possible for the new users to edit their personal profile and password. Therefore you have to access your personal UserTopic. This is not soo trivial but it`s worth a try, here we go…

1) Search Workspace “DeepaMehta”
2) Reveal Memberships and the Container appears
3) Type your Username as a Filter-Property of the Container and press Enter

Another two features were finally implemented which are concerning the Demo Mode of an Applet which shows a specific TopicMap. In the past the deleted Containers in a Demo Map couldn`t be revealed again, so it happened from time to time that a Demo-User opened up a Demo Map, but couldn`t reveal anything cause the containers were removed from the view. Additionally every Demo-User is now able to use the “Search”-Command for revealing new types.

Attention with the default installation of 2.0b8 rc`s

Filed under: Develop — Tags: , , — Malte @ 12:42 PM

We recently found a very heavy bug with the new HSQLDB support, it will make your whole corporate memory unusable. This DB is the new default installation choice since the first release candidate of the new 2.0b8. So please avoid creating webpage-topics and also don`t enter one into a property field. It has something to do with the interpretation of our SQL Statements from the HSQLDB. Enrico and Joerg talked about that issue already and they will try to upgrade our Statements to Prepared Statements until next Tuesday, this will solve the issue. We will provide you the new binaries here and additionally a small guide for updating them, as soon as possible.

Until then we recommend everyone to backup your whole corporate memory within the Administration Workspace on the Corporate Memory Topic. The backup file will be stored in your documents repository.

A great thank you for helping us identifying this issue goes out to Marek from London, he spent hours of work and his whole cm was destroyed within a simple action, at least this now helps all of us.

The Demo Server is fresh again

Filed under: Common — Malte @ 12:20 PM

I am very happy to say that from now on we all have the demo server refreshed with new binaries and we are running on the improvements from the longest gap in deepamehta releases! We don’t have a final release yet, so if you experience some problems please leave a comment or use our messageboard. Since we still experiencing troubles sometimes within a sun 1.6.03 VM loaded as an applet from the browser, comments with a small sys-report would be very helpful to track further installation or configuration issues. For running on our demoServer you can also use your own client, connecting with the following line:

on unix like machines
./run.sh dmc -Ddm.host=www.deepamehta.de

In over 50 “Shared Structures of meaning”, the deepamehta.de corporate memory connects, on April the 1st nearly 600 testers in collaboration. Our users come from all over the world, from all kind of institutions and have all kind of working fields. You think, “what the ***” does he wants to tell me? Just that there is great mixture of users who are currently registered on our server for testing purpose and now they are all able to get in touch with an association, ;)

We have currently a lot of anonymous users and the others we have tried to categorize a bit, here you maybe get a better intention.

* over 175 Freelancers from working field like Information Design,Web Production and others
* over 57 Scientists and Researchers from disciplines like Teaching, Medicine, Biology, Psychology Multimedia and Theology
* over 45 Business Testers from different disciplines
* over 44 Students mostly from Computer Science, Philosophy and Journalism
* about 15 Artists, Activists and Interdisciplinary workers
* about 15 Journalists and Bloggers

Joerg also provided us yesterday the last DeepaMehta 2.0b8rc3.zip package which you find here.

The current improvements are summarized with,

* Extended Readme
* First Version of the English Readme
* 2 Bug Fixes, one for “MS Windoof” and one about joining and leaving “Shared Workspaces”

Have fun and thanks to all who made this possible!

New “Your Maps” Section

Filed under: Common — Tags: , , , — Malte @ 2:42 PM

Since I don’t have that much time at the moment cause of starting university-projects, i hopefully find the time to deploy the fresh code on the demo server within the next few days. I just renamed the page above from “Your Screens” to “Your Maps” :) . Since it was very easy for me to import the provided TopicMaps from Matthias into my CM, i want to use this section to collect some content which maybe interesting for some out there, feel free to import these maps into your own DeepaMehta CM.

To import these maps into your own Corporate Memory, you can download the .zip files and choose within your Personal Workspace the “Import Topic Map” Command, then select your file of choice.

Has someone already some interesting maps to share? I would be happy to hear from you.
