Every person I meet in climbing gym defines their life in two words: BC and AC: Before Climbing and After Climbing. Had the same experience as OP, thanks to it, I am more fit than ever and have a much better social life :)

So true

its also very annoying that one can't have two test names where one is substring of other

Thats pretty rad! How many papers were you hauling!?

Regardless of the growth discussion, I liked reading the newsletter! Thank you for curating it :)

That indeed feel fast, awesome stuff!

I'm unconvinced with this article. Whilst obviously a smart guy, I don't think Lemire really works on the same problems most of us do. Looking at his posts and publications it's generally high peformance work on problems that are small in scope. I suspect most people actually work on far bigger projects than he does! Neither do I see from that arctile that he's actually used a modern debugger to its full potential. I rarely step through code in slow motion, but sometimes it's great to see program state. If there are thousands of files in a project I don't know well, I can put breakpoints to test hypotheses about my understanding.
