  • Linux was developed by Linus Torvalds at University of Helsinkyi, Finland. Today Linux becomes to compete with windows operation of Microsoft. and is adopted worldwide on IBM products. The British government is viewing Linux as a desktop operating system. In Tunisia, Linux is under consideration as the governmental operating system. Even Sun Microsystems, the powerful supplier in workstation and sewer market, is working on developing ways in using Linux. is now getting further attentions on governmental level in several countries. The growing interests in adopting Linux in computer operating systems are not on a personal preference level any more. A number of companies and organizations, even some governmental administrations start to see its potential capabilities and are looking for ways for its applications. The necessity of teaching Linux in university is, therefore, imminent and should be discussed in course development without delay. The purpose of this paper is showing the things to be considered, problem analysis and some solution as grafting Linux in university education.

  • With the recent wide adoption of Linux in the fields of IoT, embedded, mobile, desktop and server industries, the importances of understanding the Linux system architecture as well as customizing the Linux system are increasing very steeply. Accordingly, the capabilities of building every component of Linux system from source code files have been important. The LFS (Linux From Scratch) site[1] guides the steps of building the basic Linux system from source files. The steps consist of build host preparation step, temporary system building step, final system building step, and system configuration and boot preparation step. However, the underlying concepts behind the steps used in building LFS are difficult to understand, particularly to the beginner. This paper analyzes the LFS build steps and reveal the core build concepts and principles used in each step. Additionally, this paper shows the measured package build times obtained from our build experience.

  • This paper describes an in-depth study on the effect of students' writing of a reflection journal on academic achievement in Linux courses. For this purpose, students who took a Linux class were surveyed. Those participants were divided into two groups; an experimental group and a control group. Their academic achievement was compared and analyzed for this study and reflection journal was applied for 6 weeks after middle test. The results suggests that task achievement, expectation, learning persistence, self-efficacy, learning attitude, satisfaction in writing a reflection journal, and subject study were improved for the students who wrote a reflection journal. In addition to this, it suggests that the writing of a reflection journal has a significant effect on academic achievement in Linux subjects. It is meaningful for teaching skill of computer engineering education.

  • The most commonly used navigation systems work on Windows CE platforms. Linux-based embedded terminals have price competitiveness, because Linux is a free operation system. In order to develop map services on Linux-based embedded terminals, there were a number of technical hurdles that had to be resolved. Since the Linux-based embedded terminals is a low power, low cost, and small size platform with low processing capabilities, we must have developed the spatial database engine that minimize the number of disk accesses. We solved problems that are the processing korean language and the lack of debugging tools on Linux. In this paper, we has developed the spatial database engine and user interfaces on hand-held terminals based on embedded Linux for implementing the location based map system With view of this implementation results, we confirmed the possibility of using our embedded linux terminal as telematics terminals or navigation terminals.

  • In this paper, we describe the issues associated with implementing embedded Linux system. As an example of embedded system, a router which utilizes the powerful networking capability of Linux is implemented and the details of porting Linux to the dedicated hardware is discussed. Several efficient methods to avoid performance degradation resulted from porting lap top computer oriented Linux to embedded system are suggested. To verify the eligibility of the method to embed Linux into standalone system and to see the performance of the implemented router, comparison data with one of the most popular routers is presented.

  • Linux has peculiarities of safety, flexibility, and open source. and Linux supports various hardware platforms. But because general Linux was designed for high performance H/W, Linux has several points to support for embedded system with limited resource. Specially, a main point is booting time that is spent to tens of second. In this paper, we purpose a fast booting scheme of Linux for Embedded System and estimate a performance of scheme purposed through realized prototype. Specially, to reduce booting time in environment of embedded system, we optimize boot loader, kernel and root file system. As a result, boot time reduce 28 second to 11 second in HBE-EMPOS II.

  • Many people is studying the embedded system. The embedded system becomes a small size device. The DOM memory is using in the mobile device and small site devices. This paper proposes light-weighted Linux O.S that is running onto the DOM memory. The embedded system with the DOM must have a light-weigthed O.S due to the memory space restriction. This paper designs light-weigthed Linux O.S for the DOM memory. The new designed LILO boot loader boots the new designed light-weigthed Linux O.S as a normal Linux O.S. This paper experiments comparing the designed new light-weigthed Linux O.S with a Linux PC.
