I popped in for a few minutes to verify something. I'm ... over this whole annual what's new presentation stuff. I just don't care anymore. And honestly the three presenters I saw didn't even seem like they rehearsed at all. They just read from the prompter and tried to put excitement in their voice at the same time and it just fell flat.
I don't know about now, but when I was in college some couple of decades ago we were told during orientation that of the roughly 200 or so of us only about 3 would complete the degree. My degree is a BSCpE so not really CS. More like if CS and EE had a bastard child. I would guess they were off by a few, but no more.
The problem is once you change the ingredients, you're not making the same recipe. Sure the alternatives may turn out better, but rate the original a 1 star and then list what changes you made.
Ratings for recipes never make sense anyway because if one reads the reviews they're always of the sort, "I LOVE THIS RECIPE! I used buttermilk instead of Milk, doubled the sugar, used almond extract instead of vanilla. This recipe is AMAZING!"
