    4. In Nix, different users can have different “views” on the set of installed applications. That is, there might be lots of applications present on the system (possibly in many different versions), but users can have a specific selection of those active — where “active” just means that it appears in a directory in the user’s PATH. Such a view on the set of installed applications is called a user environment, which is just a directory tree consisting of symlinks to the files of the active applications.

    1. Mobile Based User-Centered Learning Environment for Adult Absolute Illiterates

      This study reviewed the education of absolute illiterates globally. It was based on the creation of game-based learning (GBL) which provides a user-friendly learning platform with little cost and little intimidation for the learner. The research also identified 60% of the world's illiterate population residing in rural areas with little access to computers and educational centers. The GBL environments created real world environments that allow learners to practice real-life scenarios in familiar surroundings using 3-D technology. The study also adapted a English language program to meet the needs of various languages. The context of the game is a farmer and a wife then acquire items and count them in their native language. The numbers used in counting are spoken and the game produces the correlating number so the learner becomes familiar with the written form of the letter. In conclusion, the participants identified that the mobile learning was more beneficial than PC applications due to unreliable electrical service at home. The mobile system was also available on demand.and applied to participants real-life usage.
