Pages with category Web Server

  • One thing we do with lists on a website is to put a small image to replace the default bullet with something that looks nice in the theme.

    If you are still reading the documentation on how to place an image in a list to replace the default bullet and what you read is some talks about list-style-image then you are in the wrong direction. Of course, this works great with Mozilla. But Internet Explorer does not understand the concept of list-style-image at all.

  • Whenever you run many applications on a server, such as many instances of your web server (i.e. Apache), you may want to know how much of the system is being used. This can be important to avoid overloading your system.

    The load is computed by the kernel. The kernel knows how many processes are running and how much processing power your server has (i.e. how many processors.) With that information, it infers how many processes are being held back for a period of time. The default periods are 1, 5 and 15 minutes (I'm sure you can recompile your kernel with different timings!)

  • This page has empty paragraphs at the top (before this line), at the bottom and in between each paragraphs. In a way, this is a weird module!

    It use the MO Paragraph trimmer filter1, written in PHP for Drupal 6.x, to remove all of those empty paragraphs. Sadly, there isn't a good way for you to check the page source, but you can test by posting a comment (I think...)

    The idea ...

    • 1. Available on the Made to Order Software website.
  • Moving a website to a new server

    Now and again, you have to move a website from one server to another.

    There are good and bad things about that, the main problem is with dynamic websites. Why is that? Simple: a dynamic website expects to access a database and if you hit the wrong server, that will go bad.

    What's the best solution?

    1. Install your website on the new server, make sure it loads okay (you may want to use a test sub-domain name to make sure, although that's not a rock solid proof since some things may use a fully qualified URL)

    2. Change the IP address in your ...

  • Embedded videos from YouTube.com used to work just fine on my website.

    Today, though, I just noticed that my video was not showing up on one of my pages. Looking into it, I found out that the problem was the protocol.

    I'm not too sure whether it was my browser or YouTube,com (although I'm not too sure how YouTube.com would know...) but the fact is that the iframe source was using HTTP and the page I was viewing used HTTPS.

    By editing the page and changing the YouTube.com video from HTTP to HTTPS resolved the issue. It is generally much better to always use encryption anyway.

  • As I am developing a set of pages for a customer, I ran in an intersting problem: my JavaScript function could not properly define the sizes of a box.

    That box is heavily tweaked with the CSS assigned to it, as well as all of its neighbors. So I thought that may have something to do with it.

    What I hadn't realized so far is that the ready() function of jQuery() is called once the script that includes it is ready (as in loaded) and not once the document as a whole is ready (done loading, i.e. onload event.)

    With that knowledge it was easy to understand that I was actually finding myself ...

  • Hmmm... Okay... so Facebook has a latency, but ping.fm does not seem to take anything in account!?

    I'm wondering whether ping.fm checks the PTR (whatever that is, hey?!) and if incorrect, refuses to forward the post. That would make sense since the PTR is 99% of the time wrong when spammers send emails.

    Well! Today it worked 8-) After more than 7 tests because I did not always increment that number, but still. That's good. I'm moving forward. More soon!

    This is the title of your node: [].

  • Why is my nameserver IP address not changing?

    If you have a domain that you use as a nameserver (instead of using your domain name provider name servers), then you will need to maintain the IP address of that nameserver.

    You can (and should) define your nameserver IP address in your zone. This is fairly straight forward. Simply define the ns1, ns2, ns3, etc. as a regular address and also mark them as NS entries:

  • Playing around with facebook for a couple weeks now and I bumped into a new one!

    Yep! There is a limit to the number of friends you can have on Facebook... It is 5,000±10.

    This explains why I have found several people with multiple accounts. That's the way to circumvent the limit. With 3 accounts, you can get 15,000 people in your circle.

  • I worked on a site a week ago or so and checked it with IE 8 but not IE 7...

    The customer then contacted me saying that some images were "completely" off. (about 30 pixels)

    The image being off was actually centered. IE 7 and older does NOT properly reset the text-align CSS settings. So the parent setting leaks in the children instead of the chidren using the default as they should. So that one was easy, I just added a text-align: left; in the next <div> statement and got that to work right!
