Ivan: "If we start to add additional variables to the equation, maybe other database will win". Translation: some other database CAN be better than oracle. It's up to a company to decide what their requirements are, THEN optimally select the database system they need in order to provide the best overall service. Large companies might not be conservative. It might be that they used my logic above and realized that Oracle is not the panacea that everyone thinks it is. It's like the old adage: nobody ever got fired for buying IBM. In the database world, that's Oracle.

P.s. For writing a X-Window Manager, I would recommend you have a look at the UWM sources (http://uwm.sourceforge.net/). These sources can easily give an impression on how to implement your own window manager using the XCB-Library for interfacing with the X-Window system. This will give you a relatively simple interface to manage windows, draw graphics, translate mouse movements etc. Starting with this interface you could then start to move the mouse using voice commands or raise windows.

105 Is the discipline "Computer Science" a "Natural Science"?

Theoretical computer science is a branch of mathematics and/or logic. I could consider it a "natural science" in that it studies the fundamental properties of information and computability. The "laws of computability" are just as real, fundamental, and important as the laws of physics. Programming is an art or a craft, for which you need both mathematical thinking and engineer skills. Large scale programming becomes mostly a matter of methodology (with sociological aspects etc.) and engineering. Interface design etc. is mostly applied psychology. The notion "computer science" is not well defined, as it can include any of the above and more.

Hi, in my experience, conceptual structure provides students mark their relation to current and future techniques in lifelong learning of new languages, algorithms and methods. That said I believe that conceptual structure should be as flexibe with solid knowledge, what OO can give an initial course to students.

Johann, You wrote: "The question is: Is the retinoid system model able to deal with N-dimensional problems in order to hypothesize its universality for a general intelligence?" The retinoid system alone is essential for representing the volumetric space (the world) within which the intelligent system exists, but various other kinds of cognitive mechanisms are needed for the system to exhibit general intelligence (solving N-dimensional problems) In the cognitive brain model that I have proposed (see The Cognitive Brain, MIT Press 1991), the minimal neuronal structure and dynamics of these required mechanisms is described. An overview of the cognitive system is given here: http://people.umass.edu/trehub/thecognitivebrain/chapter16.pdf If you consider the functions shown in Fig. 16.1, I would say that, in principle, we can see how all the operations, with one exception, can be realized in an artifact employing current technology. The one exception is retinoid space -- the space of subjectivity/consciousness! I have asked many knowledgeable investigators and so far no one has been able to give an example of an artifact that is able to create a global analogical representation of the volumetric space in which it exists that also includes its own fixed locus of spatiotemporal perspective.

5 What is diffrence between framework, methodology, approach, model?

In context of software, a framework is an abstraction in which software providing generic functionality can be selectively changed by additional user-written code and providing application-specific software. In general, a framework is a real or conceptual structure intended to serve as a support or guide for the building of something that expands the structure into something useful. A methodology is the systematic, theoretical analysis of the methods applied to a field of study. It encompasses concepts such as paradigm, theoretical model, phases and quantitative or qualitative techniques. A methodology does not set out to provide solutions but offers the theoretical underpinning for understanding which method, set of methods or so called “best practices” can be applied to a specific case. A systematic approach can be defined as "a process used to determine the viability of a project or procedure based on the experiential application of clearly defined and repeatable steps and an evaluation of the outcomes. The goal of a systematic approach is to identify the most efficient means to generate consistent, optimum results A Model can be defined as "Graphical, mathematical, physical, or verbal representation of a concept, phenomenon, relationship, structure, system, or an aspect of the real world. The main objectives of a model include (i) to facilitate understanding by eliminating unnecessary components, (ii) to aid in decision making by simulating 'what if' scenarios, (iii) to explain, control, and predict events on the basis of past observations. A Model ranges from simple sketches to computer programs.

Throughout my teaching experience, mostly in introductory programming, I have encountered the insidious impact of the implicit beliefs such as: if one does not "get" something very quickly, this means one lacks aptitude. Students with such beliefs give up in the face of difficulty and in the face of criticism. I believe this is what Carole Dweck refers to as the "fixed mindset".

That's true Muhamed. It is like a case where we need to test a system with an unknown state named A, and we suspect that this system's nature might give us a fictitious state named B. Since information from a system with an unknown state can not be trusted, thus the only method is to compare the state A to the properties of the state A itself. This will not give a full solution, but will indicate which is the more probable to pick, state A or B. The solutions given above suggest that the system is to be projected to another false state, C, then if the system satisfies C then the system is B, if not it is A; while in fact this solution only complicates the problem. This is because the system might choose the other false state C and adopt it (it is in its nature), so instead of being worried about two states of the system A and B, we'll have 3 states to choose from! I think the specifics of the question and answers assume psychological reaction of the subjects; a case where logical probabilities are with no use at all when we know that the tested system didn't have a (psychological space)-sort of.

I'm not sure if you are referring to length as in the physical size of the thesis or the duration of time spend on creating the thesis but I'll assume you are referring to a word count or page count. Some universities have a page-count requirement and therefore you would expect to see doctoral theses of over 150 pages. However, when a page-count requirement is not imposed, you would find shorter theses as well. One doctoral thesis that I read is only 60 pages. The largest section would be the literature review and ensuring that all the relevant theories have been synthesized in the literature review tends to increase the page-count length. If you can cover all of the needed literature to establish the context of the study and describe the analysis in a manner that the study can be replicated, you would meet the objectives of the thesis.

Dear Jan , At the beginning thanks for your interesting. The Main Goal is Design the Programming System can apply to any person in education environment to give u report of how u can managment your time in optimal method, I will using the people in education enviromaent as input to design that system. I hope find better methodology to time management for each student, researchers, ...act. Of course this including many parameters different from person to another in the same environment. The main stages of the system I'll start systems to develop a set of questions and ask a group of people that at least 500 people to answer them in order to set a first, what number of hours utilized and what are the number of hours wasted and possible through the answers put you that the person exploited his time optimally or well or are bad. The second phase teach people to exploit their time optimally develop new questions answer it by the person who exploits his time well in addition to new questions answer it by the person who exploits his time badly The third stage: Depending on 500 sample attemplt to building mathmatical models combines among the variables that I obtained from the above answers The final stage: any sample new comes not intervene to answer questions so as to identify their ups benefit from the time butthere variables apply to on mathematical model There are three tools you loved her experience in that system 1.
