"When I started working on PCs back in the mid-80's, there were thirty-six individual memory chips to be inserted in motherboard sockets. Today's computers don't have half that many individual parts! But the basic tool for troubleshooting PC problems remains unchanged - it's your brain. Swapping parts without thinking about it may work in production environments where there are endless supplies of spare parts lying around, but if you're trying to troubleshoot your home computer or out on a field service job, you won't have that luxury. The majority of computer problems turn out to be software issues, especially malicious software. But intermittent hardware failures can baffle the best technicians, and the only way to work around them is to adopt a systematic approach to troubleshooting rather than shooting from the hip. The approach I teach through my websites and books is to a process of elimination that narrows down the possibilities until the failure can be identified. When you master the basic troubleshooting technique, you'll be able to apply the lesson to technologies and situations not covered here. The flowcharts below are miniatures excerpted from my book "Computer Repair with Diagnostic Flowcharts" which is used by home hobbyists as well as for a course text in technical colleges and a field guide for technicians.

"Common Core Map Grade: K Grade: 1 Grade: 2 Grade: 3 Grade: 4 Grade: 5 Grade: 6 Grade: 7 Grade: 8 Grade: 9-12 Standard Description Videos Exercises Grade: K 2 VIDEOS 2 EXERCISES Counting and Cardinality K.CC.1 Count to 100 by ones and by tens. K.CC.2 Count forward beginning from a given number within the known sequence (instead of having to begin at 1). K.CC.3 Write numbers from 0 to 20. Represent a number of objects with a written numeral 0-20 (with 0 representing a count of no objects). K.CC.4 Understand the relationship between numbers and quantities; connect counting to cardinality. K.CC.4.a When counting objects, say the number names in the standard order, pairing each object with one and only one number name and each number name with one and only one object. K.CC.4.b Understand that the last number name said tells the number of objects counted. The number of objects is the same regardless of their arrangement or the order in which they were counted. K.CC.4.c Understand that each successive number name refers to a quantity that is one larger. K.CC.5 Count to tell the number of objects. K.CC.6 Identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group, e.g., by using matching and counting strategies.1 Comparing Whole Numbers 2 Comparing Whole Numbers 3 K.CC.7 Compare two numbers between 1 and 10 presented as written numerals. Geometry K.G.1 Describe objects in the environment using names of shapes, and describe the relative positions of these objects using terms such as above, below, beside, in front of, behind, and next to. K.G.2 Correctly name shapes regardless of their orientations or overall size. K.G.3 Identify and describe shapes (squares, circles, triangles, rectangles, hexagons, cubes, cones, cylinders, and spheres). K.G.4 Analyze, compare, create, and compose shapes. K.G.5

"It's a one-hour introduction to computer science, designed to demystify "code" and show that anyone can learn the basics to be a maker, a creator, an innovator."

One Laptop per Child and Marvell have joined forces to create a tablet computer that delivers a a better educational experience for schoolchildren in developing countries. This partnership may go a long way toward the nonprofit's group of getting $100 computers in the hands of every child.

Perhaps you have wondered how predictable machines like computers can generate randomness. In reality, most random numbers used in computer programs are pseudo-random, which means they are a generated in a predictable fashion using a mathematical formula. This is fine for many purposes, but it may not be random in the way you expect if you're used to dice rolls and lottery drawings.

"Raspberry Pi, the affordable, credit-card sized computer, has inspired tinkerers everywhere. Originally designed to get kids interested in computing, it has also developed a following among programmers looking for a smaller, cheaper medium for projects. "

"f you've got school-age kids, you know when they're working on reading and math. But if their homework includes loops, goto commands, and branches, don't be alarmed. They're probably learning to code, and that's a very good thing. From Code.org's Hour of Code to coding camps and afterschool classes, computer programming is hot -- and, in a technology-fueled world that's only going to grow, coding is an invaluable 21st-century skill."
