Anyway, while at work today I had an idea to make an application for my new phone. I haven’t got particularly far with it, only creating a library with a sprinkling of methods, one to “check in”, another to search for venues based on your GPS coordinates and one to do the actual data requests.

Even if you don’t understand Python, it shouldn’t be too hard to follow along. If anybody uses this cruft, let me know and I’ll apologise directly to you.

In your css file:

background-image: url('images/background.php');

Create the file referenced above with this code:

<?php
    $numofimages = count(glob("*.jpg"));
    $imagenum = rand(1, $numofimages);

    header("Content-Type: image/jpeg\n");
    header("Content-Transfer-Encoding: binary");

    $fp=fopen("headerimage". $imagenum .".jpg" , "r");
    fpassthru($fp);
?>

and voila, random images as a background with the bonus of being able to throw in a new image without having to do any more coding.

This code assumes that your images are called headerimageX.jpg where X is a number.

I then remembered that the index.php file of a WordPress install contains something like what I was looking for. I copied it (require(‘./path/to/wp-blog-header.php’) ) into the front page along with the functions to display the header, sidebar and footer (get_header(), get_sidebar() and get_footer() respectively) and found that it worked.

Full code for this is below (assumes that your wordpress install is in /wordpress and your page is in the root of your site)


<?php require('./wordpress/wp-blog-header.php'); ?>
<?php get_header(); ?>
<div id="container">
<div id="content">
<!--your stuff goes here-->
</div>
</div>
<?php get_sidebar(); ?>
<?php get_footer(); ?>
</div>
</body>
</html>


They found nothing wrong so I moved off the motorway at the nearest junction. No problems. The guy was on his way to Dundee so he escorted me until my turn off. No problems. Got back with no problems as well.

What I think happened (I am not a mechanic, this is not meant to be accurate info) is that the lambda sensor (monitors CO2 emissions) went wonky and the engine computer decided to let me know. In the time waiting for recovery, the system reset and all was good. A similar situation happened a couple years ago, took my car to the garage and they said it was the sensor misfiring.

While in Dundee waiting for the last class of the day (3 hour gap is a bit of a pain) I went for a bit of a shop. I have been needing some new shaving soap as the stuff I have has pretty much run out. I went to Lush to see what they have and the assistant suggested to use some “snowcake” soap which seems to be made from almonds. The lady said it lathers up well so I went with it. I also got a sample of some “Prince” soap stuff. Will report on how well they work.

In the union, I found some Ubuntu Cola (site needs flash), 80 pence for 2 cans which is not bad. It is not the same folk who make the linux distribution but they do use fairtrade sugar. Unfortunatly, the taste is the same as a certain cola maker who will not be named. Had caffeine as well which is a downer for me (causes headaches, I don’t drink much caffeine at all). I have a can on my desk, not sure what I will do with it. Anyone want it?

Now for some more technical stuff. As part of my uni course, I have a module called “Enterprise Internet Solutions” which involves using ASP.Net. Initially I balked at using it but I am warming up to it. There are some niceitys to it, such as piss easy form creation and processing. It is mainly drag and drop (as is typical of Microsoft development) but you can use the code window exclusivly if you want.

What I really like about ASP.Net is that the processing code is seperated from the html/xml code used for output in the browser. ASP uses xml tags for the user interation widgets (buttons, input boxes etc) in the form

<asp:controltype ID="something" attribute="something"></asp:controltype>

This can be shortened to

<asp:controltype ID="something" attribute="something" />

so you have well formed xml empty tags. If you remember all the different attributes and control types then you can use a plain text editor which brings me neatly to my next point.

ASP.Net aparrently works with Mono on linux so that is where I will be going if it works. Won’t be using a huge clunky expensive IDE, I will be using vim instead (emacs users, direct flames to /dev/null). Hopefully I can get it working with MySQL as well.

On a further tech note, Stanford university has released a bunch of courses online.

I still consider the script to be in beta. It would be nice if folk could test it and report on any errors you encounter (particularly file size related).

I am blocking php asp and python scripts as they are most likely to run on the server and are capable of owning me (which I do not want happening. What other extensions should be blocked on a Linux server?
