Ripped, hacked, and put together from the Winsor & Newton site.
Like everything you learn in elementary school, the color system they taught you is also wrong. We are taught when young that the three primary colours - red, blue and yellow - are all that are required for colour mixing. In fact, in pigment form every colour has both a masstone and an undertone which is different to the next colour.
For example, a blue pigment will have either a red undertone or a green undertone in comparison to another blue pigment. French Ultramarine is a red shade blue whilst Prussian blue is a green shade blue.
So, red, blue and yellow alone are not the whole story and in fact six colours provide a wider base for colour mixing: a red with a yellow bias, a red with a blue bias, a blue with a green bias, a blue with a red bias, a yellow with a red bias and a yellow with a green bias.
Three Primary Colours
Theoretically, the three primaries are magenta, cyan and yellow. But, remember that each artists’ colour has a masstone and an undertone; that artists require a package of handling properties and that permanence is also important. The recommended primaries therefore offer the best practical mixing properties combined with permanence wherever possible.
Listed below are the recommended primaries for each Winsor & Newton range:
Artists’ Oil Colour:
Transparent Yellow, Winsor Blue
(red shade) and Permanent Rose.
Artists’ Water Colour:
Winsor Lemon, Winsor Blue
(red shade) and Permanent Rose.
Artists’ Acrylic Colour:
Azo Yellow Medium, Phthalo Blue
Red Shade and Permanent Rose.
Artisan Water Mixable Oil Colour:
Lemon Yellow, Phthalo Blue (Red Shade) and Permanent Rose.
Artists’ Oilbar:
Cadmium Lemon, French
Ultramarine and Alizarin Crimson.
Griffin Fast Drying Oil Colour:
Winsor Yellow, Phthalo Blue
and Permanent Rose.
Designers’ Gouache:
Primary Yellow, Primary
Blue and Primary Red.
Winton Oil Colour:
Cadmium Lemon Hue, Phthalo
Blue and Permanent Rose.
Cotman Water Colour:
Lemon Yellow Hue, Intense
Blue and Permanent Rose.
Galeria Acrylic Colour:
Lemon Yellow, Winsor Blue and Permanent Rose.
Note; It is often a surprise to artists that Cadmium Red is not recommended as primary red in a three colour selection. Permanent Rose produces much cleaner and brighter violets and oranges, because it is closer to magenta.
The Six Colour System
A broader spectrum can be mixed with six colours as discussed under Basic Colour Theory earlier. As a learning exercise, the move from three colours to six also begins to introduce other variables like opacity, tinting strength, drying rate, and granulation, depending on the type of colour used. Here are the recommended six colour palettes:
Artists’ Oil Colour:
Winsor Lemon, Winsor Yellow, French Ultramarine, Winsor Blue (green shade), Permanent Rose and Cadmium Red.
Artists’ Water Colour:
Winsor Lemon, Winsor Yellow, Scarlet Lake, Permanent Rose, French Ultramarine and Winsor Blue (Green Shade).
Artists’ Acrylic Colour:
Lemon Yellow, Azo Yellow Medium, Ultramarine Blue, Phthalo Blue Green Shade, Permanent Rose and Cadmium Red Light.
Artisan Water Mixable Oil Colour:
Lemon Yellow, Cadmium Yellow Hue, French Ultramarine, Phthalo Blue (Red Shade), Permanent Rose and Cadmium Red Hue.
Artists’ Oilbar:
Cadmium Lemon, Cadmium Yellow Pale, French Ultramarine, Manganese Blue Hue, Permanent Magenta and Cadmium Red.
Griffin Fast Drying Oil Colour:
Cadmium Lemon, Winsor Yellow, French Ultramarine, Phthalo Blue, Permanent Rose and Cadmium Red Medium.
Designers’ Gouache:
Lemon Yellow, Permanent Yellow Deep, Phthalo Blue, Ultramarine, Scarlet Lake and Alizarin Crimson.
Winton Oil Colour:
Cadmium Lemon Hue, Cadmium Yellow Hue, French Ultramarine, Phthalo Blue, Permanent Rose and Cadmium Red Hue.
Cotman Water Colour:
Lemon Yellow Hue, Cadmium Yellow Pale Hue, Ultramarine, Intense Blue, Permanent Rose and Cadmium Red Hue.
Galeria Acrylic Colour:
Lemon Yellow, Cadmium Yellow
Deep Hue, Ultramarine, Winsor Blue, Permanent Rose and Vermilion Hue.

If you're looking for a twitter client for ubuntu, look no further than the ubuntu repository. In the add remove applications, if you search for twitter, it'll return three results: Twitter, gTwitter, and Twittux.
Get gTwitter.
This is the client I've been using with my ubuntu box.
The ubuntu client twitter is just a prism wrapped twitter. They suck. The Twittux would close the window if you click on the [x], although it does sit on the tray. I couldn't find any homepage for the two on google.
gTwitter, is almost like Twitterrific for the mac, but for ubuntu.

Whew! That's a long title, but it's definitely worth it! Corel has a bad history of unstable programs and bad customer support. And I don't see it changing anytime soon. As a Mac user, I don't use much of their program. Except Painter. And today, out of the blue, it decided to crap out on me. Yep. I got one of those:
This installation of Painter has been damaged or illegally modified. To the untrained eye, this might seem that I have either done something stupid and delete a file, or may have pirated (*Gasp!*) the software. Well, whoopde-fuckin-do. You know what? Corel treat people with both disorder the same way: With a cold shoulder.
After trying multiple time to install and uninstalling the damn thing, I scoured the internet. One guy/gal in a forum posted that s/he has fixed his/her copy by downloading a crack(!!) off of a hacking site. Well, that's a solution, Corel! You should distribute cracks to fix your brokkin software! But that solution is neither elegant, nor Mac-worthy.
The thing about a Mac, is we're outnumbered by the dumb people who choose to deal with viruses and all those windows crap instead of switching to a beautifully designed hardware with a revolutionary and well thought-out OS X. But enough about you PC users.
To fix the problem on a Mac, you don't need to install or uninstall or do anything, just go to your HD > Library > Preferences folder and delete the file named nTitles Product Licenses IV.
Then just load Painter! You will have to re-register so I hope you haven't thrown out your hard copy. *grin*
Now, on a PC, we have to delve a little deeper into the horrid entanglement that is the Windows Registry! *Dun-Dun-Dunnnn*
Oh, yes, this baby may look tame now, but watch out! Y'all artsy-artsy people are in for an ascii headache.
The rest of this solution is basically lifted from here. I got rid of my Windows headache so I won't have to deal with this registry shit anymore. Did I say shit? I meant crap.
you have to delete the Protexis files afterinstallation, but before trying to open the program.
So after uninstalling and then reinstalling Painter, do START>>RUN>>typeREGEDIT Search for all PROTEXIS files [two of them] and DELETE (being careful that's all you delete - remember to backup the reg first just in case). And only then open the program. Also, the one reply to that blog post was;
hey, the nudes were weird but I liked the other stuff you can draw Ah, PC, how will we Macs live without you?

The pen would sometimes fail to detect and stop working for a second until it refreshes and starts working again. While this doesn't seem like a big deal, it craps out your workflow especially when you're already in the zone and in the middle of painting or cross-hatching.
Also, I couldn't seem to revert to an older version without uninstalling the new one first… which would mean that I would lose my settings. Grrr. :S Why couldn't they make wacom settings saveable elsewhere as a file and so you can just load them and share them with people.
Of course, this applies specifically to Wacom intuos 3 driver. But I expect the entire wacom tablet series that uses this driver is affected.

As a photoshop painter, you understand the need for natural brushes, such as pencils, pastel, watercolor, to name a few, and photoshop is way behind its competitors in this front. It couldn't even rotate its canvas fer cryin' out loud.
But have no fear, one man has filled in this void for you! David Nagel! All of this brushes is now available.
Yep, David Nagel has created so many brushes for photoshop, it's website, the creative mac, couldn't even catalog it.
Seriously, the site is very badly put together, not to mention spam heavy, that it's so difficult to navigate. But oh, you so dearly need the charcoal brush! The pencil! The watercolor brush! Your life depends on Photoshop!
Have no fear! Google is here!
Just Click Here to go to google and have all the photoshop brushes you need listed. If you don't know which to get, just get Series 33 (chalk, dry brush, charcoal, pencil), and 30 (bristles, charcoal, pastel). They're the essential ones. Oh, and Series 40 watercolor.
And as you can see, David Nagle created such great brushes, the charcoal photoshop brush looks like charcoal, the pencil photoshop brush looks like pencil, the watercolor photoshop brush looks like watercolor, and the gouache photoshop brush looks like gouache!
But that's not all! He's even created the cloud brush, it's so easy to use you'll get clouds done very quickly! There's also a couple of stamps like the butterfly and various animals.
Oh, did I mention the skin brush? It even comes with a hair brush, you know to paint in those hairs when you texture your 3D model.

I thought I was gonna retire this blog, but it turned out, I kept getting computer-related stuff that I always want to share with you. ^^
Now, one thing that makes photoshop such a powerful software is the plugin. And most of us mere mortals… well, we can't even code html right to save our ass. So, the only reasonable solution to this, is having someone else to code for us. But here's the catch: Money. Well, everybody wants something for nothing, and the economic law says, where there's demand, there bound to be supplies.
And what luck would have it, here's a website that list a whole can of free plugins for Photoshop. And not only that, they would also provide help in case those software got outdated and won't run in your version of photoshop as much as they can.
From their page:
We are committed to cross-platform open source software and welcome discussion of any issue pertaining to the software on this page, including build issues. As a proponent of open source, I like to plug for this page. ^^ However, be forewarened, they have plugs that aren't free. :(
Create .ico on your mac with Photoshop
I wanted to create a .ico icon for one of the many websites I maintain. And it turns out, photoshop can't open nor save .ico. :( Luckily, someone GPLed a .ico plugin for photoshop that would also run on a mac. ^^ You can download it from the aforementioned website. It's listed at the top of the list as of this writing.

UPDATED for HARDY HERON. Thanks to bigdee973. ^^
I mean, FULLY WORKING not those half working tablets where the pressure don't work 100% and the expresskeys and the touch strip not working. I mean this guide is to help non-programmer artists get their ubuntu system working with their wacom tablets. Just like they do in their Apple Macs and *shudder* windows.
The first thing I'd like to point out is that, this guide is not intended for programmers. This guide is for computer dummies like myself who wanted to escape to a free OS. If you're just trying out to see if wacom works under ubuntu, don't waste your time. The tablet is not as easy to setup as in a Mac or Windows. No complete installer is provided by wacom. However, your tablet will work with Ubuntu out of the box. There's no extra setup needed. But the expresskeys and the touch strip will not work by default.
To get a wacom tablet fully working, the only mental faculty you need is already present if you have ever finished a Legend of Zelda game. Except zelda II that one just sucks. I'm sorry if you ever played that one. Or the CD-i Zelda.
Now, some of the instructions presented here will be in the form of codes. It'd be nice if you try to learn and understand what they mean. They will be very useful to your Ubuntu future. But if you're intimidated by strings of nonsensical characters randomly strung up by an evil genius geek deep in his dragon infested dungeon, just think of it as looking for a particular icon in other OSes like OS X or windows. Or just looking for the any key. Only, in this particular OS, it's already provided for you to copy paste.
I hope you're running Ubuntu 7.10 or higher. The codename for that version is Gutsy Gibbons. If you're not, please run your automatic software update till you run Gutsy. (If you're already running previous version of Ubuntu, you wouldn't need to read the dumbingdowness parts of this guide)
So, anyway, let's begin.
Although Wacom tablet runs out of the box in Ubuntu, you'll need to enable it in Ubuntu. That's just how linux works. If something is unnecessary, it just won't load it. Unlike windows which becomes bloated because it loads practically everything at starts up.
Part 1. Running a wacom tablet.
This part is lifted from ubuntuguide. You might want to use that one if you already know what you're doing. And return here for the second part.
First, you'd have to fire up the terminal. Go to Applications > Accesories > Terminal
 And boom! You got this terminal window:
 Hooray! You've just prepared yourself everything that is necessary to complete this howto guide. Isn't that easy? Even mere mortals can do it. Most people are just too chicken to try.
Now let's open the editor and edit xorg.conf. All you need to do is copy this:
gksu gedit /etc/X11/xorg.conf And paste it to the terminal by pressing Ctrl-Shift-V. Then just press enter to open the editor with xorg.conf. You might be asked for password now. Just put in your login password and it'll open the editor.
Look for the part that says:
#Section "InputDevice"
#Driver "wacom"
#Identifier "stylus"
#Option "Device" "/dev/input/wacom"
#Option "Type" "stylus"
#Option "PressCurve" "50,0,100,50"# Custom preference
#Option "ForceDevice" "ISDV4"# Tablet PC ONLY
#EndSection
#Section "InputDevice"
#Driver "wacom"
#Identifier "eraser"
#Option "Device" "/dev/input/wacom"
#Option "Type" "eraser"
#Option "PressCurve" "50,0,100,50"# Custom preference
#Option "ForceDevice" "ISDV4"# Tablet PC ONLY
#EndSection
#Section "InputDevice"
#Driver "wacom"
#Identifier "cursor"
#Option "Device" "/dev/input/wacom"
#Option "Type" "cursor"
#Option "ForceDevice" "ISDV4"# Tablet PC ONLY
#EndSection And remove the # sign before each line until the three parts looks like this:
 Then save.
And we're done with part 1! All you have to do is restart and you'll have a fully working tablet now! Or, if you're smart, just press Ctrl-Alt-Backspace.
Part 2. Getting to drive the expresskeys.
If you restarted as told, and done playing with your working pen, you'll notice that the expresskeys and the touch strips don't work. If you have a Graphire 3, then you can immediately draw in Gimp. Have fun! But the rest of us, we have to increase our productivity by utilizing these touch strips.
The first thing is to launch the Terminal as we did in the first part.
Then you paste this code:
sudo aptitude install xlibs-dev Run it by pressing enter, and it'll display a jumble of things. Don't worry about it. After it's done, just paste in and run this code:
sudo aptitude install wacom-tools Those two codes will ensure that your computer is fully prepared to compile the program that will run expresskey and touchstrips.
Now, launch your firefox browser, and head to Expresskeys. And get the latest tar/gz thing. As of this writing, it's expresskeys-0.4.1.tar.gz.
Then you just right click on it and select extract here . After that, in your terminal, go to the folder that you've just extracted. In short, paste and run this code:
cd Desktop/expresskeys-0.4.1 Change the version number as necessary.
And inside that, run these commands line by line. Don't try to do it all in one go, copy one line and past it then run it, after that run the next line. It's maybe tedious, but if anything goes wrong, you'll know which part went wrong and it'd be easier to fix.
./configure
make
make install After that, we'll need to open xorg.conf again, so like before, just run this command:
gksu gedit /etc/X11/xorg.conf
And add this section immediately above or below (it doesn't matter) the three we edited in the first part.
Section "InputDevice"
Driver "wacom"
Identifier "pad"
#c~b Option "Device" "/dev/ttyS0"
Option "Device" "/dev/input/wacom"
Option "Type" "pad"
Option "USB" "on"
EndSection Then look for the part that says
Section "ServerLayout" And immediately below the line, add:
InputDevice "pad" #c~b Intuos3 And that's it, we have set up the necessary programs to get the touch strip and the expresskeys to work.
Just save and reset your machine or press Ctrl-Shift-Backspace.
Part 3. Near instant gratification.
Just like in part 1, start your terminal. And run this code:
expresskeys -d
If you did everything right, it wouldn't spit out any thing and returns to the terminal like nothing happened.
Fire up gimp and try out your touchstrips and expresskeys!! :)
But wait, what if you want to customize the expresskeys and the touchstrip?
It's easy, you just need to know the key combination and edit the expresskeys config file.
To edit the config file, first you must be able to see it.
Go to your home folder: Just select Places > Home Folder. If you're running ubuntu, I don't need to illustrate this anymore. In your home folder menu, press Ctrl-H to show some hidden files and folder (Ctrl-H again to hide them. Look for a folder named .expresskeys (with the . (dot) before the expresskey) and inside, you'll find a file named intuos3.conf1. Just double click to open it.
Follow the instructions in the file to edit each and every function of the expresskeys and touchstrip.
Oh, and one more thing, to get the keycode, start your terminal and enter:
xev
A small window will appear and your terminal will be spitting a bunch of code. Put your pointer inside the small window and leave it there. Don't move even for a pixel. If you're using the tablet, just lift your pen.
Press the key that you want the keycode of on your keyboard, and immediately it will appear on your terminal as marked:
Good night good luck, and most of all, have fun with your fully functional tablet! :)
UPDATE for Ubuntu 8.04 HARDY HERON:
***FOR THOSE OF YOU USING UBUNTU 8.04 HARDY HERON***
before you install expresskeys u have to edit a file before you compile and install. its not that hard... what u have to do is download the latest version of expresskeys which is of today 5/23/2008 expresskeys-0.4.1 (here is the link...if link is broken just google expresskeys-0.4.1 and download file).
http://freshmeat.net/projects/wacomexpresskeys/
after u download the tar/zip file, you will untar/unzip it into ur home folder...and then Change line 462 of the file src-expresskeys/get_device.c from:
if (xdevice_list[i].use == IsXExtensionDevice) {
to these two:
if (xdevice_list[i].use == IsXExtensionDevice ||
xdevice_list[i].use == IsXExtensionPointer) {
after that save the file and close it. and proceed with the installation as described in the tutorial...but if ur too lazy to back track like me then just open terminal and copy and paste below...
sudo aptitude install xlibs-dev
...this installs the files u need to configure and install express keys...then in terminal...you cd into the directory of the expresskeys folder that u untared/unzipped into. which should be your home folder and
sudo ./configure
sudo make
sudo make install
restart your PC then open terminal type in
expresskeys -d
your keys should work...u could also add this to your startup session by going into system>preferences>session
u restart your computer and then open terminal again and....
expresskeys -d
and ur expresskeys should work play with the strip to see

When your blog post came up to the hundreds or even thousands, one day you'd want to let people click on random post. Or, maybe if your blog is a personal blog, and not a spam blog that aims only to suck traffic, you might one day want to flip thru your blog randomly, just like when you speed read thru your personal diary.
There are many ways to add this capabilities to blogger. One popular way is by adding a random I'm feeling lucky widget to your blog. However, I find that these clickable links are best put near your navigation buttons, not somewhere in your sidebar. In blogger, that is the older post, newer post and home button. Besides, it looks horrible to see a lone navigation button hovering in the middle of those stuff on the right.
So, what other ways can we use to achieve this? The most obvious is a blogger hack. I have sampled several blogger hacks that allowed this, however, some would get deleted if you change some layout and stuff on blogger. This hack has survived several blogger changes.
So, what you do, is, edit your templat HTML, make sure that expand widgets is selected, then add the following right before the </head> tag.
<script type="text/javascript">
//<![CDATA[
var _yourBlogUrl = "http://insertblogurl.blogspot.com";
function randomPost() {
var script = document.createElement("script");
script.setAttribute("type", "text/javascript");
var theUrl = _yourBlogUrl
+"/feeds/posts/summary?alt=json-in-script&callback=getTotalPostsCallback&start-index=1&max-results=1";
script.setAttribute("src", theUrl);
document.documentElement.firstChild.appendChild(script);
};
function getTotalPostsCallback(json) {
var totalResults = json.feed.openSearch$totalResults.$t;
if (totalResults > 0) {
getRandomPostNumber(totalResults);
}
};
function getRandomPostNumber(totalResults) {
var randomNumber = Math.floor((Math.random() * totalResults)
+ 1);
getRandomUrl(randomNumber);
};
function getRandomUrl(randomNumber) {
var script = document.createElement("script");
script.setAttribute("type", "text/javascript");
var theUrl = _yourBlogUrl
+"/feeds/posts/summary?alt=json-in-script&callback=getTheUrlCallback&start-index="
+ randomNumber + "&max-results=1";
script.setAttribute("src", theUrl);
document.documentElement.firstChild.appendChild(script);
};
function getTheUrlCallback(json) {
var theUrl = json.feed.entry[0].link[0].href;
window.location.href = theUrl;
}
//]]>
</script>
And then, add the following where you'd like the random link to appear in your blog.
<a href="javascript:randomPost();">View Random Post</a>
In my blog, I put it under
<div class='blog-pager' id='blog-pager'> Please thank Purple Moggy for creating this code. :)

Using the infrared camera in the Wii remote and a head mounted sensor bar (two IR LEDs), you can accurately track the location of your head and render view dependent images on the screen. This effectively transforms your display into a portal to a virtual environment. The display properly reacts to head and body movement as if it were a real window creating a realistic illusion of depth and space. By Johnny Chung Lee, Carnegie Mellon University. For more information and software visit http://johnnylee.net
This was posted over at penny arcade today, and I think it's really interesting. Nintendo itself has demonstrated an astounding variety of ways to use the wii remote like in the game Wii Sports, Wii Play and Wario Ware. It even changed the landscape of 2D gaming as demonstrated in Super Paper Mario.
The catch is, Nintendo meant for the Wii for gameplay only. And that is correct for the Wii Remote. (it's not Wiimote, you morons) But, wouldn't it be great, if you can use it on a PC? Especially after seeing that video, don't you wish you have that capability on a 3D program? You'd only need to move your head a little to see the 3D-ishness of your objects. Or perhaps, use a Wii remote to edit your mesh?
What Johnny Lee has demonstrated is only a proof of concept. It has not been implemented to a practical everyday use. I hope someday someone with a good programming skill can connect the Wii remote to Maya or Blender.
