Journal, LaTeX and EPS

I have to learn on how to use LaTeX as it will ease the usage of formatting the journal by using their template (without reformatting the whole document). After consulting my SV, he said that I need these softwares before proceed to learn LaTeX :

- MikTex : http://miktex.org/2.7/setup
- A software that can save image/figure/object as Encapsulated PostScript (EPS) file - I choose to use CorelDRAW as it was in my program list
- WinEdt
- PostScript
- GhostScript

The 'oldtimer' normally use the earlier version of Ms Visio to convert to EPS. But since Visio 2003, the function was disabled. However it is still possible to use Visio - there's a converter (http://wiki.lyx.org/Windows/MetafileToEPSConverter) where we can save the figure as windows metafile (wmf) or enhanced metafile (emf - which is better) format and converts to EPS using the software. Other alternative is to use OLETeX (http://oletex.sourceforge.net/) where it can converts any OLE object to EPS file.

Can't wait to start a lesson on LaTeX!

Stop script in wordpress

I've been facing this prob since updating the wordpress to version 2.7 or 2.8 (can't remember exactly) - which I used to manage my official makeup site, themakeups.com. The 'stop script error' occurs each time I made and publish a new post. I tried to ignore the error, but since it consume a lot of memory and heavy load (not to mention hangs my browser), especially when I'm doing 'mass update' for all the latest job I've got, then I started to seek for the solution. Refer here : http://wordpress.org/support/topic/206177

Original post was by Craig Childs, many thanks to him. And just in case the link will expire, the solution is as below:

What was happening was when the Write>Post screen was opened, it would sit then eventually throw up an unresponsive script error which stemmed from: /wp-includes/js/jquery/jquery.js

It essentially rendered the Wordpress admin useless unless you wrote a draft elsewhere, such as an external blog editor, and saved it as a draft - the Manage section was unaffected.

In any case, if you find yourself with the same issue, it's a simple edit of the wp-admin\edit-form-advanced.php file. Just remove this line:

$metadata = has_meta($post->ID);
list_meta($metadata);

I need XP back to run Matlab

I hv prob with matlab in vista. Can't run the installation (for v7.3) and can't open the program (for v6.5). Never had this kind of prob while using xp last time. It's troublesome to reformat & install xp, and also tedious to dual boot (vista & xp); so I've decided to use xp as virtual machine. Found this : http://lifehacker.com/software/windows/geek-to-live--run-windows-xp-inside-vista-with-virtual-pc-238071.php

hope this will work well & run matlab properly.

-Update (24th July, 10.36am):
Hv successfully installed virtual machine xp, but still can't install matlab. This is due to some reason (all the troublesome in vista), and the only solution is to download a fresh version of matlab from mathworks, and re-install. Let's try this!

- Update (24th July 2009, 4.08pm):
Mission accomplished!

Computer Vision Test Images

22nd July 2009 - I was given a few tasks by Dr.Faizal (my SV) as the startup of my 3rd degree. This is one of them. The images will be used in initial experiments (just to test the color techniques). The image collections found :

1. List of various images from various sources (source1) : http://www.cs.cmu.edu/~cil/v-images.html
2. List of various images from various sources (source2) : http://www.iro.umontreal.ca/~mignotte/TestImages.html
