There was originally a bug in the GAlib random number generator... if I remember correctly, the guy who identified it told me this was found (or demonstrated) by making a scatter plot of generated numbers an observing there was a pattern to the data.
Gridogram is a word game where the goal is to trace words in a letter grid to find a hidden quote. Behind the scenes, creating the letter grids for quotes is not obvious: the linked page describes the approach taken.
There's a bit of logic involved, a bit of maths with undirected graphs... hopefully it's of interest! Oh, and there's an interactive bit where you can try creating a grid for a quote, which in itself is kind of a fun challenge.
I was a big fan of Wave. One aspect I really liked that I haven't seen in other apps is other people would see the letters/words you typed as you typed them, making for very active discussions... But then some people also hated that others could see their typed-out thought process and typos before they finished editing and hit send.
Really appreciate the feedback, and glad you like the quotations. I haven't settled on whether to add links, but the text not being selectable wasn't intentional - have pushed a change to allow selecting the text, I hope that improves things.
Thank you! Would never expect anyone to find all the words, but the full alphabetised list is useful to help box in the yellow words that are in the quote. Some of the words in the list are indeed pretty arcane, but I hope it can be interesting for players to see new words, and that those don't really interfere with the fun of the game. By the way, you can tap a word to see its definition.
Thank you! Yes it is tricky... what kind of shortcuts do you mean? One optimisation I've done to narrow the search space is account for symmetry, that's a shortcut in a sense.
I've spent a lot of time finding apps I trust enough to leave my kids mostly unsupervised with. For me it's mostly boiled down to finding trustworthy app publishers, I listed some here a while ago: https://medium.com/@jacksonpauls/apps-for-preschool-kids-304...
One thing I've noticed is that bing webmaster tools will report "The title is missing in the head section of the page" when there is a title, but no <head>. Maybe bing can't properly crawl pages without a <head>. Another service I've used had the same problem, but can't remember which.
So it might be worth being careful with omitting <head> - and maybe other tags, I'm reconsidering whether it's a good idea.
"In addition, the Government will work with organizations such as the Linux Foundation’s Core Infrastructure Initiative to fund and secure commonly used internet “utilities” such as open-source software, protocols, and standards. Just as our roads and bridges need regular repair and upkeep, so do the technical linkages that allow the information superhighway to flow."
