Yesterday I found a relly cool functionality in my laptop BIOS. Everyone of you might know the problem, that the USB ports of laptops doesn’t provide a power supply. So I can’t charge my mouse battery or my MP3 player when the laptop is switched off.

I do have a cool 220V USB adapter, but I don’t take it with me all the time. But now I found this mentioned functionality in the BIOS that enables you to do that. The first problem was to figure out how to access the BIOS. As I administrate a lot of PCs and I even earned a lot over the years, I always forget which F-Key to press on which PC (or the Delete-Key).

On a server I have to administrate, I had some problems to set up the Backup Manager through the Plesk Panel. So I decided to write a small tutorial on how to set up the Backup Manager on a 1&1 Dedicated Server Linux. But it might the the same on many other servers as well.

The 1&1 Server uses Plesk version 9.2. The first step is to logon to the Plesk Panel. On the “Home” page you should find a button for the Backup Manager in the Server section:

Backup Manager

Many uses autocompletion on their website. It’s not only an impressiv but also a very user-friendly feature. It can also help to have valid data within a form. But you always have to validate the data on the server before saving them.

Today I want to show you, how easy you can create a autocompletion for Google-Maps-Addresses using Scriptaculous. As you can’t access an external website with an AJAX-Request, we have to use a small Skript as a gateway between Google Maps an your website. So let’s start with this server-side script this time:

Now that I’ve already written three WordPress plugins, and even use many other plugins, I have noticed some things that should be considered when creating a plugin. Due to the fairly extensive WordPress Plugin API creating a plugin isn’t very complex, but unfortunately, most of the plugins lack quality. So everyone who wants to create a plugin should care about certain things.

Create something new

The hardest part is probably to find a good idea for a new plugin. The three plugins I have written were founded by a specific need. A certain feature wasn’t included in the main features of WordPress and there was no plugin in sight, that could offer this feature.

Many hosters offer cheap domains without a webhosting package. Some of those hosters e.g. Strato only give you the option to use a frame redirect with this domains. But sometimes you can’t see that restriction when you order the domain.

Some might be happy, as they have a free hosting package with a very long URL, so they can use the frame redirect to only present a short URL to the visitors. But there’a a catch with frame redirects.

This plugin enables blog admins and editors to manage the notification of incomming comments. As WordPress only has the option to notify on every comment, the email account of the admin may recieve many email each day. Notification is also limited to the admin only, so only the admin user will recieve an email for incomming comments.

Using the plugin you can subscribe to a RSS feed that contains even comments that has to be moderated. Every feed entry has the links to delete a comment, mark a comment as spam or approve a comment, if the comment has to be moderated. If a comment has been marked as spam, it will no longer appear in the feed.

My blog runs on a virtual server with plesk as administration tool. Installing the blog I had some issues with file permissions. On the wordpress website you can find a tutorial to change file permissions, but it doesn’t answer all problems with a system that has Plesk installed.

At first you have to decide where to install the blog. You can choose one of your domains or a subdomain. You might have to create it and activate the PHP support before.

Who doesn’t know the problem with external links. You don’t want to expect target=”_blank” to your users so you let open links in the same window. To enable users to see that a link is external, you want to mark them. So a user can than decide to open it eventually in a new window/tab themselves.

I have seen multiple solutions for this problem. Some have been executed server-side, some of them used heavy JavaScript function client-side. Most of the time, the scripts searched for all links within a page to change them afterwards.

This plugin enables you to run your blog in a different language than the backend of your blog. So you can serve your blog using e.g. German as the default language for the users, but keep English as the language for the administration.

If you like the plugin or if something is missing I would like to here it. Just leave a comment on this page or on my WordPress plugin page.

In my previous post about the Line-Duplicater I had to find specific tags within a DOM element. As I found nothing in the Utility Methods I had to use the getElementsByTagName() function. But only with this function I couldn’t solve the problem. I also had to use the $A() function to get an array of the elements. The result for all there form input types looked like that:

$A(newRow.getElementsByTagName('select')).invoke('clear');
$A(newRow.getElementsByTagName('textarea')).invoke('clear');
$A(newRow.getElementsByTagName('input')).each(function(elm){
	elm.clear().checked = '';
});
