Japanese AI version 0.1

Over a year ago I released the concept and initial analysis of the Japanese AI project here. Since then I have been using the results off and on for translation, learning, and other projects. Not long after, I wrote a generic version of this project, AltSci Language AI using Twitter as the data source. It also utilized the Google Translate Language API to translate the conversations on the fly. It became obvious that the benefits of this type of language software would be quite useful, so I made a few quick user interface improvements to Japanese AI, so that I could release the full results.

Today I have been more productive in the tasks I want to get done than the past two weeks. What stops a person from doing what they want to do when they don't have to do anything? Procrastination, laziness, sloth, and depression are keywords for the type of feeling a person has when they are unwilling or incapable of doing what they want. The question of whether it is volition or predetermined is of great importantance. If it is volition a person can choose whether they are able to do what they want. If it is predetermined the person simply must wait until the period of inactivity is over. If we are convinced that the inaction is by choice we must find a way to force ourselves to act.
And so I have turned the corner and I don't know how. Perhaps it was encouragement from others in other projects, perhaps it's a sense of accomplishment that another project is finished. Does it make sense that a person would be unwilling to work on one project while another is in limbo or a broken state? Even if you aren't directly working on that project knowing that your future depends on it is enough to cause anxiety. This anxiety is probably enough to cause a form of depression or escapism. When I worry about the unknown I have two choices: do something about it or let it continue. Each has consequences and benefits. Often the choice to do something causes such fear and doubt that a person will avoid the very reasoning that should cause them to do something. This type of awful loop is certainly the cause of much grief in many people's lives. I am not at the point where I will give self- improvement advice to others but if my logic is correct a person might be able to understand something on their own based on my rather lame blog.

It's a pretty simple virus, so the lessons learned from analysis of this virus should carry over to more than just this virus. I tried to write it generically enough to fit any case, so when I analyze it I will compare it to other viruses and how things on the net work. I'll try to come from a neutral standpoint because the idea of demonizing or glorifying a virus are counterproductive to the task of learning what it is and why it is. I'll try to keep the philosophy in the next to last section clearly marked so people who wish can skip over it or skip to it if that's their prerogative.
Every virus needs to get onto a computer (host) somehow. Viruses of old days resided on floppies. These days they are much more often carried by computer networks, the internet being the largest. If you think of floppies and other medium as sort of sneakernet, then all viruses need a network. This method of transfer ends up running code on a system that is commonly unintended by the user. In the SSH Bruteforce Virus, I spread the virus using a dictionary password cracker that supports Secure Shell (SSH). This is very simple and uses an open source library for SSH (libssh-0.2). When my virus successfully logs into a remote system, it copies a tar archived version of itself to the victim. It extracts the archive and executes the payload script. The remote system now has an exact copy of the virus. This is the definition of a replication virus. At this point, the system is infected and can infect more systems.

I don't have enough time to go into details. You can tell that it's me because the links are pretty obviously to video and my site.
