It’s good to be back online. This blog has been down for few weeks because I had some problems with my previous host. I lost some files so it took me a while to restore all data from the backup. Fortunatelly, I haven’t lost any written data (posts, pages etc). The only files missing were media files like images. I have uploaded back those pictures I had in the backup, I will try to replace the rest of them with new similar images soon.
I have already drawn new pictures for Adjacency list model and Nested set model posts. They don’t look quite as good as the previous ones. That’s because I have used GIMP to draw them this time and I have put only a little effort into it because I’m kinda busy right now
