It’s International Women’s Day and it’s a call to #pledgeforparity. A parity check in computing code is an agreed way for checking if any bits of the data have been altered. It verifies whether the data has been sent correctly between computers. Eddie Woo aka @misterwootube is a successful, passionate teacher who is very good at demystifying these things and who has a commitment to creating clear communication in his classroom so that his students really understand what he is teaching. He explains parity checks well. A computer can go ‘Huh?’ like we do when we are not certain we got the right information or interpreted something correctly. If we are going to #pledgeforparity for International Women’s Day then we should be looking at women and going ‘Huh?’ when it’s not right. Parity is the official value of something . Parity is there in different contexts, but it will always mean that two things are equal. So how are we treating women? How are we creating internet images of them? How are we treating girls and women on web sites and in social media? How does the way women are portrayed on the internet compare with men? What images do women have to look at about themselves? What do men have to look at? This is an area which needs scrutiny and one we could address easily. Looking forward to the parity. I am so over going ‘Huh?’ when I go on different sites and social media venues.
