To go Open Source or go proprietary? There is a common conception that open-source is unsafe and insecure and therefore companies should rather go for proprietary solutions. They think that because software is termed "open-source", that the world can see the vulnerabilities of the software and might exploit it, and less informed people tend to think that open-source software can be modified while it is running.

It is an ingenious bootleg solution that involves taking off one shoe, and a blanket that disguises some of the method.
In this video, we practice describing solutions in English. For example, if the problem is that you have stomach problems, the solution is that you should go to the doctor. Should simply means a good idea or a recommendation. You could also say the solution is that you need to go to a doctor. For the next example, if your problem is that your car won't start, this means your car will not start. You could also say that your car does not start, which is a good way to describe the problem. For t...

Chrome has an option which allows you to choose something called "side tabs" which moves the tabs for those websites and webpages you have open from the top of the browser to the left side. But how do you get side tabs in Chrome? lifehacker has the answers.
Today's word is "panacea". This is a noun which means a remedy to cure all diseases or a solution for all difficulties.
Solving 6 math problems using different methods is the idea behind this video. First, you make three rows of numbers vertically from 1-9. All the numbers match across for example, 1 1 1, 2 2 2, 3 3 3, and so on. Each set of numbers creates a mathematical problem who's solution is the number six. These problems require some thinking to solve. The only one that is immediately apparent is 2 2 2=6 which is, of course, 2+2+2=6, (3x3)-3=6, the square root of 4 =2. This done on all three of the four...
Given a equation of a line, you can graph the line. A system of equations is nothing but equations of more than one line. In a single equation all the points that lie on the line, satisfy the equation of the line. Similarly a solution of a system of equations is points that satisfy each and every equation of that system. A system of equations can have a single point as solution when the lines intersect at a common point, or have a unlimited points in solution when the lines overlap on each ot...
A method for solving a linear system with no solution is described. The method is described in 4 steps. The first step in the method is designed to solve a linear system that is described consist of “solving by graphing”. Details for “solving by graphing” first consist of finding points to graph using two different equations. The second step in the method consist of placing the points from both equations on the same graph in order to find out if bo...

In this video the instructor shows how to solve a system of equations by elimination method. First you need to know how many possible number of solutions you can get by solving a system of equations. There are three possibilities. In the first case there are two lines with different slopes, so they intersect at a point which is the solution to that system. In second case there can be two lines with same slope but are parallel to each other. In this case the system has no solution. In the thir...
