6.172 Performance Engineering of Software Systems (MIT)
Modern computing platforms provide unprecedented amounts of raw computational power. But significant complexity comes along with this power, to the point that making useful computations exploit even a fraction of the potential of the computing platform is a substantial challenge. Indeed, obtaining good performance requires a comprehensive understanding of all layers of the underlying platform, deep insight into the computation at hand, and the ingenuity and creativity required to obtain an effec

3.1 Involving all of the senses

Becoming more aware of the everyday world around you involves more than just looking. If writing is a perceptual art then perception should involve all of the senses, not just the visual. You must also start to smell, feel, taste and hear the world you are trying to realise. So, in the made up scenario, when you see the man with the Scottie dog you might be too fearful to stroke his dog, but perhaps you could touch the cold metal bar where the dog was tied up – after he is gone, of course!

Restoring sight
Three blind people have had their vision partially restored, thanks to an electronic implant. In this video, one of the patients sees his hand again for the first time since going blind. He then successfully reads a word and recognises some everyday objects. The microchip works by using diodes to replace damaged light-sensitive cells in the retina. For more details on how the technology works, read our news story here: http://www.newscientist.com/article/dn19667

3.2 Making sense of the metaphor

The metaphor of the juggler keeping the four balls in the air is a powerful way for me to think about what I do when I try to be effective in my practice. It matches with my experience: it takes concentration and skill to do it well. But metaphors conceal features of experience, as well as calling them to attention. The juggler metaphor conceals that the four elements of effective practice often seem to be related. I cannot juggle them as if they were independent of each other. I can imagine

Gantt charts show all the key stages of a project and their duration as a bar chart, with the time-scale across the top. The key stages are placed on the bar chart in sequence, starting in the top left-hand corner and ending in the bottom right-hand corner (Figure 7 – Gantt chart for directory production). A Gantt chart can be drawn quickly and easily and is often the first tool a project manager uses to provide a rough e

2.3 Other influences on market demand

What about other variables which may affect demand? Let us consider four such variables. As is often the case in economics, the first two points involve understanding some rather formal relationships between variables, in this case price and income.

  1. The price of other goods. Two goods x and y are known as substitutes if the quantity demanded of good x increases after a rise in the price of good y. The

The framework for easy intelligent tutor programs creation
In this paper the framework for intelligent tutor programs creation is described. It separates the logical part of tutor program and technical parts like user interface, database connectivity, etc. The intelligent program is built in specially developed graphical tool by means of performing primitive actions to create task model as a graph with states and conditional transitions. So it may be composed by a teacher with base programming skills.
