Found a good post on how to use the  rescue mode in Hetzner to setup a Logical Volume that spans multiple drives. This plus vsftpd can help setup Terabytes of space for storage as backup. In any case you should not use Hetzner for anything closely resembling a legit online service, website etc. It is only […]

This is surprising and I am not sure the any advantage it would have over Threads+Process. Heron also has done […]

Unlike Python, I do not clearly know what is out there for Java. Rails is easy, if you use Rails you use ActiveRecord and forget about anything else. Hibernate […]

I was having this terrible problem that prevented use of my home server. I was starting to regret many things like buying a refurbished Worskstation, the refurbished memory DIMMs or that fact that I chose Centos7 over Ubuntu which I use for development. A careful and determined Google Searchathon revealed the issue. My reason to […]
