gfh | 6 years ago | on: Ask HN: How do I make sure my kids are safe online?

I don't want my young kids being exposed to a lot of trash online. But we like to laugh at funny pictures/memes together. So, one weekend I built a primitive tool that lets me share funny images with them: cleanhumor.net

I have a python script that pulls down posts from /r/funny. Reddit has some filtering options in their API, which I use. My script then rejects any that have caption words on my blacklist. It also does OCR to look within the image, and applies the blacklist there, too.

The remaining images I review manually. They show up on my phone along with large "accept" and "reject" buttons. When I click accept, the image and caption become available on that little website I made for my daughters. Many images aren't funny, and I personally still wade through lots of trash. But overall it has been fun for my family.

It sounds like a well done class! I've seen that many lectures follow a pattern of starting in the low-level details of a topic and slowly working up to something useful by the end. I find I don't appreciate or particularly remember the details because I don't understand the motivation. So, I prefer an approach which starts out with the big picture of what cool thing is possible, and then the details take on more value and meaning for me.
