    “Hailong did a great job with what he was able to. Some of the things we asked for were just not possible - we learned later that the code we asked him to fix was very outdated and needed to be rewritten, but this was not his fault. He did have some trouble with understanding syslog, but was able to overcome it. In all, he did not give up and did deliver what he could, so we are happy with him.”
