Finally! Started on Objective C
I’ve finally got round trying some Objective C programming beyond outputting “hello world” with what is in effect ANSI C. I’m coming from a Perl background with a a smattering of other experience such as ANSI C, ASP and PHP … Continue reading
Perl FTP Recursive Binary Issue
Another day….. Today’s kick in the nether regions was using Net::FTP::Recursive which was defaulting to ascii transfer mode when doing a bulk website transfer. The issue was not with the text (html type) files but with the images. I believe … Continue reading

After yesterday’s success with the ZFS configuration I’m hoping to perform some snapshots and get the compression to be a bit better. I was a bit disappointed with the compression ratio yesterday which was a pitiful 1.15x. I’ll be cheating … Continue reading
