Welcome to the LinuxFocus November/December 2001 issue

November really feels like Christmas time. When it is December and Christmas then there are sooooo many people in the shops running around to buy presents and Christmas advertisements are everywhere. It's not funny and it's almost too much.
Therefore this is now the LinuxFocus Christmas edition with LinuxFocus crispy chocolate coco cookies:

Ingredients:

- 2 x 100g bar of milk chocolate
- 1 cup shredded coconut
- 1 cup cornflakes

Directions:
Carefully melt the chocolate in a saucepan. Add the shredded coconut into the melted chocolate and mix it with a spoon. Next, add the cornflakes and stir it until all the cornflakes are covered with brown chocolate and coconut. Take 2 teaspoons of the mix and roll it into a ball. Place separately on a cold plate and let these crispy chocolate coco cookies cool in the fridge for 15 minutes.

The LinuxFocus Tip

How to design a homepage that many people can read?
When you design your homepage you probably want other people to be able to look at it. HTML is a standard but how a browser reacts to faulty html is not standardized. This is why poorly designed pages will have a pleasant look in one browser but look distorted and ugly in another one. The best solution to this is to not only look at your page with one browser but run it as well through a html verification tool such as tidy (click to get to the tidy-homepage):
just run:   tidy -e index.html
where index.html is your homepage and you will get a list of errors if there are any. Tidy can as well fix automatically some errors or indent the html code nicely. It's all described in the man-page that comes with tidy.

The W3C provides as well an online link checking and html validation service at:
http://validator.w3.org/.
In this case you don't need to install anything. Just run your homepage through this validator. It's a rather strict validator, maybe sometimes too strict but it gives a good indication.

Broken links are annoying and there are tools to check links. You find one on the above validator page and you can download different link check software at: http://linkchecker.sourceforge.net.
A very fast checker is blnkcheck. It can check several thousand links per second but it checks only relative links. blnkcheck is part of a package called webgrep (click to get to the webgrep-homepage).
