What is the use/meaning of 'swap area' while linux installation? How can I resize an LVM partition? (i.e: physical volume) I want to shrink my second (LVM) partition, in order to create a new partition in the newly freed space. I am using the Live CD to do so, because I know I can't resize/move this partition while it is in use. When I opened GParted in the Live CD, I realized that I could not resize the partition, because when I right-click it, the option "resize/move" is disabled.  I tried to unmount it, to "lazy" unmount it (umount -l /dev/sda2) but it didn't work.  A screenshot from GParted: Uses of the 'Golden Ratio' I have heard much about the numerous appearances of the ratio found in nature: 1.6180339887.  Are there any actual mathematical uses that have been found of this number? What are its advantages? Just curiosity, really. Check out the below program.   try {     for (String data : Files.readAllLines(Paths.get("D:/sample.txt"))){         String[] de = data.split(";");         System.out.println("Length = " + de.length);     } } catch (IOException e) {     e.printStackTrace(); }   Sample.txt:   1;2;3;4 A;B;; a;b;c;   Output:   Length = 4 Length = 2 Length = 3   Why second and third output is giving 2 and 3 instead of 4. In sample.txt file, condition  for 2nd and 3rd line is should give newline(\n or enter) immediately after giving delimiter for the third field. Can anyone help me how to get length as 4 for 2nd and 3rd line without changing the condition of the sample.txt file and how to print the values of de[2] (throws  ArrayIndexOutOfBoundsException)?

Hide some fields in the NewForm.aspx for a custom list How to create svg symbols that have modifiable fill color, stroke color and stroke width? I want to create some svg symbols for Qgis using Inkscape, those symbols must have attributes as described in the question. For the last two days, I have been experimenting as instructed by  and mimicked some symbols came bundled with qgis that have desired attributes without any success.  Finally I experimented with the simplest form of symbol: I created an svg that contains only a circle in Inkscape and tried to modify it.  The original file () have this line:  &lt;path    sodipodi:type="arc"    style="fill:#ffffff;fill-opacity:1;stroke:#000000;stroke-width:1.01988637;stroke-miterlimit:4;stroke-opacity:1;stroke-dasharray:none"   I modified it into:  &lt;path    sodipodi:type="arc"    style="fill:param(fill) #ffffff;fill-opacity:1;stroke:param(outline) #000000;stroke-width:param(stroke-width) 1.01988637;stroke-miterlimit:4;stroke-opacity:1;stroke-dasharray:none"   Saved as  and selected it as point symbol, but Qgis couldn't change all three parameters at the same time.  What did I do wrong or should do differently?  My system: Qgis 1.8.0 on Ubuntu 12.04 64 bit, Inkscape 0.48, Gedit 3.4.1 text editor. I have this run.sh file, and I've create a symbolic link into my desktop.   When I double-click on it the file the following dialog appearsr    And I have to click on "run" each time.

Taxonomy count per Post type Below is the code i use to output the post tag (taxonomy) count/number. I want to be able to split the count based on post type that the taxonomy features in (rather than the total number).   So i have the default "post" Post type, aswell as "blogs", &amp; "pics". I want the taxonomy count to display something like: x posts | x blogs | x Pics              &lt;?php             $tags = get_tags( array('name__like' =&gt; "a", 'order' =&gt; 'ASC') );             foreach ( (array) $tags as $tag ) { ?&gt;                 &lt;li&gt;                                                 &lt;a href="&lt;?php echo get_tag_link( $tag-&gt;term_id ) ?&gt;"&gt;                                   &lt;span class="name"&gt;&lt;?php echo $tag-&gt;name ?&gt;&lt;/span&gt;                         &lt;span class="number"&gt;&lt;?php echo $tag-&gt;count ?&gt;&lt;/span&gt;                     &lt;/a&gt;                 &lt;/li&gt;             &lt;?php } ?&gt; Elsarticle - Abstract two columns wide Cron Job not working in plugin I have written a plugin that will convert posts to excel format and then email the .xls to an email id.

How can I add an image at its original resolution?  For example, if I add a 60x60 pixel image, it should appear very small in the final 1080p render. I am currently reading Murphy's ML: A Probabilistic Perspective. In CH 3 he explains that a batch update of the posterior is equivalent to a sequential update of the posterior, and I am trying to understand this in the context of his example.  Suppose $D_a$ and $D_b$ are two data sets and $\theta$ is the parameter to our model. We are trying to update the posterior $P(\theta \mid D_a, D_b)$. In a sequential update, he states that, $$ (1) \ \ \ \ \ \ \ \  P(\theta \mid D_{a}, D_{b}) \propto P(D_b \mid \theta) P(\theta \mid D_a) $$ However, I am slightly confused as to how he got this mathematically. Conceptually, I understand that he is saying the posterior $P(\theta \mid D_a)$ is now a prior used to update the new posterior, which includes the new data $D_b$, and is multiplying this prior with the likelihood $P(D_b \mid \theta)$. Expanding the last statement out, I have, $$  P(D_b \mid \theta) P(\theta \mid D_a) = P(D_b \mid \theta) P(D_a \mid \theta) P(\theta) $$  but are we allowed to say $P(D_a \mid \theta) P(D_b \mid \theta) = P(D_a, D_b \mid \theta)$ in order to make the connection in (1)?
