Moblin, Linux for ultraportables

David — Wed, 27 May 2009 09:43:12 +0000

Moblin is an open-source operating system designed for ultraportables and cell phones.

The OS, based on Linux, is made to handle multimedia content (videos, musics, photos) and Internet.

Intel created Moblin in 2007 for its Atom processor, and called the Linux Foundation to develop the project. The sources becoming open, all the developers can contribute to the project.

Create a contact page in PHP

David — Sat, 16 May 2009 16:20:36 +0000

If you have a web site, you probably want to allow visitors to contact you. But without reveal your electronic address.

Of course, it can easily fall in the robots hands which scan the web to make listings. Then your box would be full of spams!

The solution is a contact page, where people can send a message to you without seeing your e-mail directly.

Javascript comments check

David — Tue, 25 Nov 2008 19:13:47 +0000

By default in blogs, when we post an invalid comment (missing field, invalid e-mail...) we arrive on a error page. Unfortunately this method has the following disadvantages:

te be often a standard blog page, white, without your theme,
to require a new page download,
then visitors must go back to correct the comment.

In this article, I will show how to verify the comment fields on your blog instantly with Javascript by showing a error dialog box if something is missing.

Force to download .PDF

David — Fri, 26 Sep 2008 19:22:45 +0000

With some PDF reader software, including the most popular Adobe Acrobat Reader, the default setting is to open PDF files in the browser when we click on a link to a PDF.

As a webmaster you can force the browser dialog box allowing to choose to open it directly or to save it..

Images in PHP with GD2

David — Sun, 31 Aug 2008 21:05:03 +0000

As I already said earlier, PHP can not only make web pages. We can also generate images. First, let's see how to add a text on an image.

As it's a very long tutorial, which will be followed by other articles about images management in PHP, I divided it in two parts.

Images in PHP with GD2 - Part 1 image creation

Possible uses include

create nice image titles with complex fonts like above (see the image address ),
add a signature text on all your images,
make a captcha (anti-spam image),
put dynamic text coming from PHP variables in images.

English version of the site

David — Fri, 15 Aug 2008 12:50:19 +0000

Pffff, I has worked hard (I need to congratulate myself!). I prepared an English language version of Azur Dev computer news & web tutorials.

I'm not sure azure.ironie.org is very anglophone, but as I'm locked on the ironie.org, azure is the translation of azur, and moreover the final e is like the e of English (but undoubtedly I am the only one to see it!).

The goal is to translate only the articles which can interest the rest of the world. Some news I publish are too French. I hope that this translation will attract more visitors than the French site. Answer in a few weeks...

The good HTML code to insert Flash

David — Tue, 29 Jul 2008 19:28:47 +0000

I must admit we are not helped, everywhere we can share Flash animations or videos, the code they give is wrong. Except a few passioned developpers, most people copy-paste the given code even without knowing the element does not exist in HTML!

Moreover, the correct code is simpler and shorter.

Age of an article in PHP

David — Sat, 12 Jul 2008 18:25:40 +0000

I read a few days ago this article with the code to print the age of an article by Bleebot. As this function is long and not well optimized, I build my own one.

Switch from RSS to Atom feeds

David — Sat, 14 Jun 2008 21:42:25 +0000

What we generally call RSS feeds can be in fact feeds from different formats: RSS 1 (or 0.9), RSS 2 or Atom.

The last one has an advantage (very important for a real geek) on the RSS format: it's not proprietary and supported by the W3C. Moreover it brings additional elements for more content.

That's why I decide to put the link on the Atom feed on my blog. Here is how to do:

Show RSS feed on your website

David — Wed, 07 May 2008 21:18:24 +0000

There are 2 ways of showing on your website news coming from other sites RSS feeds in PHP.

• The first is to open the feed like any other file and use PHP functions on strings to build your own parser.

The disadvantage is that this method is not "portable": depending on the RSS feed version (1, 2, Atom) there are diffrent syntaxes and the code working for a feed, won't work for another.

• The second is to use an existing library, where these problem were already solved by others..

Good coding presentation

David — Wed, 23 Apr 2008 19:05:01 +0000

The code presentation in any language is a very important point to increase comprehension and "visual" resarch. At the moment and when we re-read a few weeks, or months later, a good presentation can make the diffrence between a fast developper and a laming one.

Create an intelligent search engine

David — Thu, 17 Apr 2008 15:02:02 +0000

When we build a website containing many pages based on the same template (blog, shop, forum, directory...) we always need a search-engine to extract results from the database.

Here things are getting harder, because by searching "videos" we won't find articles with the word "video" whereas it would be needed..

Fortunately, there is a solution: use a soundex. It's an algorithm which will compared words based on phonetics of the words, so the results will be close in sound to the searched term.
