Pushing the "make it worse" button on a $3.5B project sounds insane, right?
While I'm always excited for more transit in Canada, the Finch West LRT is showing #Ottawa something NOT to do for our future rapid lines like the Baseline Transitway.
Let's talk about two crucial words: Signal Priority.

The power of ordering from an indie bookstore!
I once asked a bookseller at a large indie store how many people would have to buy a book for it to get the attention of the store buyer and cause an additional order and they said: Three.
I see some book piracy discourse, and, to make a positive argument in favor of buying books, your marginal ability to influence what books get published and support the careers of writers you like is massive compared to most other forms of media.

a common defence of genAI is it’s a tool, and tools are neutral and can be used in good or bad ways
but LLMs and transformers are tools - chatGPT is a *product*, openAI are using the tools in a bad way!

Well, the settlement money has been announced. Each WORK that got thefted will be compensated $3k (split 50/50 bw publisher + author). So authors will be compensated $1500 per WORK stolen.
