Checkout the table. No 0, 1, 2,8 and 9 is not usable. no. 3 is not usable as already created a partition there. 4,5,6 and 7 is available to make partition. So, I have selected 4.

partition> 4

Enter new starting cyl[0]:

Now, check previous partition of no. 4. It is number 3. Its Cylinders count ended at 1672. So, we will start from 1673. (If there is no no. 3 that i created previously, then we would have look for part no. 1. Not 2, because it is not usable, it represents whole disk size).

Now enter 1673

Enter new starting cyl[0]: 1673

and partition size 500mb.

Enter partition size[0b, 0c, 1673e, 0.00mb, 0.00gb]: 500mb

Now enter ‘label’ to confirm your partition.

Now, check the last entry. That is the guy.

Obviously I started my RND via google. found that there is no straight forward way to solve this problem. All I found people are screaming for help.

I used alfresco-3.4.d community version with default installation in CentOS 5.6

For SMTP, i tried to use gmail. There were a number of tutorial in the web. But, i didn’t work well with me. I tried James. Its pretty easy to use. I followed this post to install it and created an user alfresco/alfresco. U need to check this post to configure james for alfresco. Which is as follows.

In james I modified /opt/james-2.3.2/apps/james/SAR-INF/config.xml

Make sure that the following tags exists in that config file with the corresponding values.

<servernames autodetect=”true” autodetectIP=”true”>
<servername>localhost</servername>
<servername>example.com</servername>
</servernames>

and

<pop3server  enabled=”true”>   <port>9110</port>
<smtpserver enabled=”true”>    <port>9025</port>
<nntpserver enabled=”true”>    <port>9119</port>

These lines are scattered through out the config file. So, don’t copy-paste it blindly, use your head. Restart James.

Now, we need to edit alfresco properties file to add the information of James, our mail server.

Find out /opt/alfresco-3.4.d/tomcat/shared/classes/alfresco-global.properties

Add the following lines.

mail.host=localhost
mail.port=9025
mail.username=alfresco
mail.password=alfresco
mail.from.default=admin@example.com

Now, we have to the work in the parallel workflow xml(/opt/alfresco-3.4.d/tomcat/webapps/alfresco/WEB-INF/classes/alfresco/workflow/parallelreview_processdefinition.xml)  file. Our goal is to send mail to each of the reviewers as soon as the initiator started the workflow. Find out the startreview node. It will be look like this,

<node name=”startreview”>
<action>
<foreach>#{bpm_assignees}</foreach>
<var>reviewer</var>
</action>
<event type=”node-enter”>
<script>
<variable name=”wf_approveCount” access=”write” />
<expression>
wf_approveCount = 0;
</expression>
</script>
</event>
<transition name=”review” to=”review”/>
</node>

now add the send mail action inside review transition. Now, it will look like this.

<node name=”startreview”>
<action>
<foreach>#{bpm_assignees}</foreach>
<var>reviewer</var>
</action>
<event type=”node-enter”>
<script>
<variable name=”wf_approveCount” access=”write” />
<expression>
wf_approveCount = 0;
</expression>
</script>
</event>
<transition name=”review” to=”review”>
<action>
<script>
var mail = actions.create(“mail”);
mail.parameters.to = reviewer.properties.email;
mail.parameters.subject = “Parallel Task started”;
mail.parameters.from = “alfresco@mydomain.com”;
mail.parameters.text = “Parallel Task started.”;
mail.execute(bpm_package);
</script>
</action>
</transition>
</node>

Wait, its not finished yet. We need to redeploy it. Find out /opt/alfresco-3.4.d/tomcat/webapps/alfresco/WEB-INF/classes/alfresco/bootstrap-context.xml find out

<props>
<prop key=”engineId”>jbpm</prop>
<prop key=”location”>alfresco/workflow/parallelreview_processdefinition.xml</prop>
<prop key=”mimetype”>text/xml</prop>
<prop key=”redeploy”>false</prop>
</props>

Make redeploy true. It will be like this.

<props>
<prop key=”engineId”>jbpm</prop>
<prop key=”location”>alfresco/workflow/parallelreview_processdefinition.xml</prop>
<prop key=”mimetype”>text/xml</prop>
<prop key=”redeploy”>true</prop>
</props>

Now, restart the alfresco service via ‘ service alfresco stop ‘ and ‘ service alfresco start ‘.

Now, check yourself if it works or not and let me know

Thanks to this guy.

Get the swftools-0.9.1 (this is the current for now):

[root@centos5 ~]# wget http://www.swftools.org/swftools-0.9.1.tar.gz

[root@centos5 ~]# tar xzf swftools-0.9.1.tar.gz

Now you have to compile it so you need to have gcc and some libraries and components installed (automake, zlib-devel, libjpeg-devel, giflib-devel, freetype-devel) so you don’t get errors during the compile process:

[root@centos5 ~]# yum install gcc* automake zlib-devel libjpeg-devel giflib-devel freetype-devel

[root@centos5 ~]# cd swftools-0.9.1

[root@centos5 ~]# ./configure

[root@centos5 ~]# make

[root@centos5 ~]# make install

n 3.4.d, the pdf2swf conversion that is used by default in preview, is broken (at least in Linux package). The reason is the corrupted library link (libstdc++.so.5). You have to fix it this way:

$ cd $YOUR_ALFRESCO_DIRECTORY/common/lib
$ rm libstdc++.so.5
$ ln -s libstdc++.so.5.0.3 libstdc++.so.5

To know more about him click here. See his photostream.

We had discuss about macro photography at photographybd.com . Macro photography is completely a new world to me. Tried to learn something from him.

Here it goes…..

First of all I’ll just share a few words about doing macro with the lit lens. The lit lens is a zoom or varifocal lens that has a floating aperture and to reduce the cost of production, these lenses are manufactured with relatively smaller maximum aperture compared to the primes(for example a kit’s max aperture range is generally f/3.5~5.6 where the largest aperture of the lens is f/3.5 at its widest whereas you can get a 50mm f/1.8 prime for almost the same cost and it is twice as fast than the kit (f/3.5~f/1.). Therefore naturally it becomes hard to spot a subject with the reversed kit lens as it allows comparatively less amount of light through it.

what is macro lens ?? wide question !! I just wanted to know, if I can use it for every type of photography !!

A macro lens is a lens capable of magnifying a subject and reflecting the life size image on the sensor(Life size~ if a bug is 8mm long then its image on sensor will be of the same length of 8mm). Macro lenses are designed to work with very little focussing distance from the subject.  But the macro lenses are not confined to working with that limited distance only. These lenses can focus up to infinity and therefore can be used for any purpose. (For example, the canon 100mm f/2.8 macro lens is considered to be one of the best lenses for portrait photography.

how important is light, if i use reverse lens..

Light I think is the most important issue if you are doing reverse macro. The built in flash of your camera is not enough to provide the required light for such delicate work so an external flash is a vital requirement. But for the time being you can search in google about making a built in flash diffuser by yourself which can improve the light a lot.

what is the difference between macro and micro photography..  (i’m unaware about micro  photography)

There is quite a big difference in macro and micro photography but often these are used simultaneously for the same purpose. Macro photography means photographing anything at life-size or larger. I have mentioned the term life-size in my second answer. On the other hand, micro photography means photographing microscopic subjects. Micro scopic subjects cannot be seen through naked eyes and this is where the difference comes in. In macro photography you can see the subject and you take a more or equally magnified picture compared to life-size and in micro photography you cannot see the subject and you take the photograph using a microscopic lens. That’s all!!

i was ur gears in facebook.. its pretty fascinating to own all of them..!! i saw a box/tube in between the camera body and lens.. i guess its called extension tube (not sure   ) .. i just want know why is that.. what is the purpose..!!

Yes, you were right about guessing the box/tube thing but it is not an extension tube. But it does the same job as extension tubes. It is called an extension bellow unit or macro bellow unit. It is like a hollow tunnel. Of the two ways of getting graeter magnification(Using close-up filters and extension tubes/bellow) this is, in my openion, the better one. Because of being a glass element, close-up filters damage the image quality quite a bit but the extension tubes or bellow doesn’t have any glass and therefore keeps the image quality intact. The purpose of using these is getting greater magnification. The more a lens or a reversed lens is extended the nore the magnification of the subject will be. There are some calculations and charts which denote the effects of extension for various lenses but describing that for now will be quite irrelevent. By simply reversing a 50mm lens quite gr8 magnification can be achieved. If it is possible, plz try that quite regularly and when you’ll face no problem with the focussing at f/11 or 16 then you can think about getting a greater magnification.

I tried with 50mm prime.. haven’t done anything well.. but still trying to understand.

Actually you can use any lens for the purpose of reversing but primes are the best ones as I have mentioned earlier. Amongst the primes, to me, 50mm is the best one for starting up because it gives you moderately higher magnification for cheap and also provides some working distance. Once you master it, go for the old wide primes (35mm, 28mm, 24mm, 20mm etc.) and those will give you even greater magnification. But, along with that, these lenses will also reduce the focussing distance and make it harder for you to do insect macro.

Tanguar haor is an important habitat for fish conservation and fish production. This not only supports fish but also other aquatic organism and vegetation. it has been declared as Ramsar Site for its ecological importance. The haor is the home of 140 species of sweet water fishes and thousands of indigenous birds. It is also an excellent wintering site for large numbers of migratory birds.

Its a beautiful village and added to my dream village.

These are my two tiny toy beasts. When I was kid, I used to have a lot of toy cars. But, in course of time I lost them all. But, my passion for cars never ended. I always carry these two along with me. I try to take interesting photo with these two.
