Fisher-Price's Cute New Toy Aims to Teach Preschoolers the Basics of Computer Programming This article was updated on Jan. 6, 2015, at 1:08 p.m. ET. Bill Gates was 13 when he started to code. Elon Musk was 12 and Mark Zuckerberg was 10. Today, there’s no shortage of books, toys, classes and camps to nudge the next generation of coders along the path to promising careers in technology. Related: Your Next Vision Exam May Involve Playing Video Games Not to be left out of the tiny tot tech toy trend, news arrived today that Fisher-Price is finally joining the race. The colorful plastic toy -- which features an adorable motorized head, twists and turns from side to side and lights up -- is called the Think & Learn Code-A-Pillar. The interlocking segmented gizmo won’t exactly educate preschool kids on the specific intricate nuances of writing code, but it will expose them to a handful of simple computer coding gateway skills overall.

MadCode: Escola de Programação e Robótica para Crianças e Adolescentes, de 05 a 17 anos de idade. | MadCode: Escola de Programação e Robótica para Crianças e Adolescentes, de 05 a 17 anos de idade. Learn Web Development with Rails: Michael Hartl's Ruby on Rails Tutorial | Softcover.io Learn Python The Hard Way With the help of this book, you will do the incredibly simple things that all programmers do to learn a programming language: Go through each exercise.Type in each sample exactly.Make it run. That's it. This will be very difficult at first, but stick with it. This book's job is to teach you the three most essential skills that a beginning programmer needs to know: reading and writing, attention to detail, and spotting differences. If you have a problem typing, you will have a problem learning to code, and especially if you have a problem typing the fairly odd characters in source code. Typing the code samples and getting them to run will help you learn the names of the symbols, get familiar with typing them, and get you reading the language. The one skill that separates bad programmers from good programmers is attention to detail. By going through this book, and copying each example exactly, you will be training your brain to focus on the details of what you are doing, as you are doing it.
15+ Ways of Teaching Every Student to Code (Even Without a Computer) According to Code.org, 90 percent of parents in the U.S. want their children to learn computer science—it will be crucial for many jobs in the near future—but only 40 percent of schools teach it. Critics claim that it is mainly the more affluent schools that offer computer science courses, thus denying those who attend poorer schools the chance to learn necessary skills. A focus on STEM is not enough: Code.org also reports that while 70 percent of new STEM jobs are in computing, only 7 percent of STEM graduates are in computer science. It is imperative that savvy schools begin to focus some STEM resources on computer science and programming. In my opinion, parents of every student in every school at every level should demand that all students be taught how to code. With the following resources, you can teach programming to every student and every age. Teaching Coding to the Youngest Students Tynker Games: Use these age-appropriate games to teach your elementary students coding concepts.
Logic in Media Queries Just in case you have brain farts about this constantly like I do. If That's what media queries are: logical if statements. And The keyword and. Or Comma separate. Technically these are treated like two separate media queries, but that is effectively or. Not Reverse the logic with the keyword not. Just doing not (max-width: 600px) doesn't seem to work for me, hence the slightly funky syntax above. Exclusive To ensure that only one media query is in effect at time, make the numbers (or whatever) such that that is possible. Logically this is a bit like a switch statement, only without a simple way to do "if none of these match do this" like default. Overriding There is nothing preventing more than one media query from being true at the same time. Media queries add no specificity to the selectors they contain, but source order still matters.
