It Depends — A dependency management app How often have you had a software deploy that broke something else you didn’t know depended on the system being upgraded? Or took a server down that you didn’t realize another system was using? Or had a production issue and realized that literally the only person who knew anything about that system was out on vacation? Remembering dependency chains, especially if they are a few steps removed, is no easy task. A Dependable Way to Track Your Dependencies With It Depends, you can easily define entities, then create “depends on” relationships with the other entities in the system. After creating some entities, and establishing the relationships between them, you can ask questions like “What apps depend on my app?” An Arc90 Lab Project It Depends is the seventh of a handful of projects to come out of the Arc90 2012 Hackathon.
9 Websites to Learn Coding As Compiled by TED May 15, 2014 Learning how to code has become an essential skill for the 21st century students. The importance of coding lies in the fact that it enables students to learn a slew of other important skills all along the way. In his popular TED talk " Let's Teach Kids to Code", Mitch Resnick of MIT Media Lab outlined a set of skills that students get to learn from coding . Code Racer that is featured in TED article has become Treehouse which brings the number of websites to 9. 1- Code Academy This by far the most popular of them all. 2- Girl Develop It One of many programs geared toward females who want to code, Girl Develop It is an international nonprofit that provides mentorship and instruction. 3- Udacity Computer Science Course ( not free) Stanford University’s Udacity is one of many sites that make college courses—including Introduction to Computer Science—available online for free. 4- Teamtreehouse 5-The Computer Club House
The Art and Craft of Programming -- Loops Loops are used to repeatedly execute some code. The most basic loop structure in Python is the while loop, an example of which is: i = 0 while (i < 10): print(i,end="") i = i + 1 We see a while loop looks much like an if statement. The difference is that blocks belonging to ifs are evaluated at most once whereas blocks associated with loops may be evaluated many many times. Another difference in nomenclature is that the block of a loop is known as the body (like blocks associated with function definitions). As Computer Scientists hate to type extra characters if they can help it, you will often see: i = i + 1 written as i += 1 The latter version is read as "increment i" and saves a whopping two characters of typing. A while loop tests its condition before the body of the loop is executed. i = 10 while (i < 10): print(i,end="") i += 1 never prints out anything since the test immediately fails. i = 0; while (i < 10): print(i,end="") i += 1 the loop prints out the digits 0 through 9: Other loops
