I'm shocked that there's an entire mini industry of sorts of pictures of younger woman posing in front of Javascript code. Not just a casual picture but with what looks like a carefully composed photograph.
Though maybe don't look it up at work.
[EDIT] You know what? I'm just gonna leave all this to retrospectives from sociologists and media studies folks in a decade or two. Any discussion about this whole slice of online life is always too much of the usual Internet misunderstanding-one-another, but with the knives out. There's a ton of really interesting stuff going on around this topic, but it's just not worth trying to discuss, no matter how much good faith is brought to the table. Suffice it to say that it doesn't look like anyone in this sub-thread has been trying to associate the OP with anything unseemly, that certainly wasn't what I was trying to do (god, why on earth would I want to?) and on re-reading my post in context it also doesn't appear to be what I did do. I'm bowing out.
A huge amount were, like another commenter mentioned, girls in yoga pants or short shorts posing with Sublime Text in the background. And they're hugely popular.
In no way do I think the original poster's feed is like this. She seems genuinely interested in coding. It just led me into this entire apparent subculture of this type of thing.
