Normally used to graphically display size information about a large amount of data it can also be used on websites to display tags. Don’t know what I mean? Then check this one out: RoomforMilk. Nice idea, Geoff Gaudreault!

]]> Today I played a bit with my fotoalbum. I learned that I made a whole lot of database queries which are not necessary at all. So I began making optimisations to improve performance.

After adding a query counter and looking at some queries and code I found out how to improve the behaviour given. The thing that created most of the queries (>60%) was the recursive function isPublished(). But this function is needed to successfully tell if an image is published or not. So what to do? Use caching!

The cache did a good job, but could not reduce the number of queries the way I wanted it to be. So I tried harder on optimising queries, loops and object creation.

Finally I could gain a reduction of about 93% of the queries made when it was not optimised at all. This is great, you know, because an image gallery should not eat that much server performance.

Well, go to my installation of fotoalbum if you’d like to see it in action. If you like it, then you can also get a copy of it! If something fails then please report it to the fotoalbum page so I can help you or at least fix the problem.

]]> Inkscape is a very simple yet powerful vector graphics program. You can create and edit any svg image and even include other images in it. It is easy to use – it took me about an hour to create this icon although I had no previous Inkscape knowledge. I also tried out some advanced functions as gradients and drawing bezier curves. It was really fun creating an icon, maybe I’ll create my own for my fotoalbum.

Inkscape

An Inkscape package is already included in my favourite distribution Ubuntu. If you’d like to have more information about Inkscape I’d like to redirect you to the Inkscape Website. There you’ll find news, an FAQ and most important tutorials to get to know how to work with Inkscape.

The Icon

The icon uses the well known question mark to represent the help functionality. It has orange background because it is meant to be included into the uni@klu homepage I’m helping out sometimes. I already did some icons on that page but never used a vector graphics program to do that (I used The GIMP instead).

It has some bezier reflections on the upper half and an oval reflection with gradient on the lower third of the icon. This way it has a very glassy look. This has not been my idea, many icon themes use this technique to create high quality icon sets. Personally I like flat icons more, but this one will hopefully be the first of a new set at uni@klu.

The Source

If you’re interested you can have the Inkscape svg file. Just drop me a line and I’ll send it to you asap.

I found out about the tutorials at the GIMP website (The GIMP), so I tried out some of them. The most impressing tutorial for me has been the “Draw A Paint Brush” tutorial by Tuomas Kuosmanen. You can see the resulting image at the left, I’m going to put the gimp source file up when I’ve got more time.

My own Paint Brush.

This is the Paint Brush in its original size, hope you like it!

My girlfriend told me she wanted to have a colour palette for the paint brush, so I tried it out. It’s not that good, but it’s a start :).

This is a merged image of the Colour Palette and the Paint Brush.
