Girl geeks at Google 02 Mar 2014 About six weeks ago I bought a treadmill desk. Now I deal with email, write code, prepare slides and even type blog posts while walking anywhere from 0.6km/h to 6.4km/h. I am walking at a steady 3.5km/h as I write this. There have been multiple studies that suggest sitting down for long periods of time is not great for your health. As a Software Engineer, I do a lot of computer work and for most folks that means sitting down. Quite a few people have asked me questions about my treadmill desk experience. The TR1200-DT3 desk treadmill paired with a secondhand motorised standing desk From Sitting to Standing When I started doing the majority of my work remotely in 2012, I decided to buy a standing desk. As the desk could only be adjusted by removing all my gear and manually shifting the shelves, it wasn't something I was keen to do very often (I recommend using a calculator like this to get the heights right).

3 Websites To Get Started With Learning C++ Programming Language Learning to program can be difficult for many, even with relatively easy programming languages. While Java is easier to get started with (where we have numerous articles here at MakeUseOf for Java as well as Internet scripting languages and deciding which one to learn), C++ may not be. However, those with some programming experience will find learning C++ less difficult than beginners, although there are plenty of good websites to teach yourself with. Why Learn C++? Why would you care to learn C++? Due to this, most programs are at least partially written in this language or its cousin, C. LearnCpp.com LearnCpp is a great place for both beginners and somewhat experienced programmers to get started with C++. Out of all the sites I list here, I recommend trying this one out first before all the others. CPlusPlus.com CPlusPlus is another great website for learning C++.

» Stop talking, start coding hilarymason.com I read Out of the Loop in Silicon Valley in the NYTimes today, which explores how and why women are under-repesented in tech startups. From the number of retweets I saw and the clicks through bit.ly links (12,579 at the time of this posting), it’s been getting a lot of attention. There are some very strong, compelling themes in this article. I don’t want to nitpick the article, but there are a few statements that reinforce the very damaging stereotypes that the article sets out to dispel. “When women take on the challenges of an engineering or computer science education in college, some studies suggest that they struggle against a distinct set of personal, psycho-social issues… Even women who soldier though [sic] demanding computer science and engineering programs in college…” I’ve been both a computer science student and a computer science professor. “Girls have certain family goals they want to accomplish,” she says. The men that I know and work with also have wonderful personal lives.
7 Apps for Teaching Children Coding Skills It's hard to imagine a single career that doesn't have a need for someone who can code. Everything that "just works" has some type of code that makes it run. Coding (a.k.a. programming) is all around us. That's why all the cool kids are coding . . . or should be. Programming is not just the province of pale twenty-somethings in skinny jeans, hunched over three monitors, swigging Red Bull. If you're concerned that that a) elementary school students don't have the ability to code, b) there's no room in the curriculum, and c) you don't possess coding chops to teach programming skills, throw out those worries. In no particular order, we have listed all the coding apps that are appropriate for young learners.

5 Organizations Helping Women Get Ahead in Tech Emily Goligoski (@emgollie) is a marketing manager at Federated Media. She produces video interviews with female entrepreneurs for Women 2.0 and writes about culture news as TheSanFranista. What happens when "equality in the workplace" is simply a numbers game? The ratio of women trained in computer science education is even lower now than it was in the 1980s. In 2008, girls made up just 17% of Advanced Placement test takers in computer science (the lowest percentage of any subject) and held less than 20% of CS degrees. To combat these numbers, organizations have sprouted to improve and expand programming education for women. Sometimes started out of frustration with the disproportionate ratio of male and female programmers, these five organizations are optimistic about building a community that includes first-time programmers and people shifting professional fields. 1. 2.
