I’ve had a bit of trouble with the old webserver and as a result i had to take it down and set up a new webserver, which has been running fine for a while now, but i have not had time to set up this blog again, also , as the old server had a disk crash i couldn’t reupload content from before the crash, i wanted to fix this blog for a while now but i simply haven’t had the time to work on it.
