@lisavogtsf i really enjoyed your tweets from Strange Loop, Lisa
While I’ve never been I’ve always wanted to and seeing the highlights that people like you post every year reminds me how cool a place it is. Thanks for that.
@alpha i regularly tell people the time I interviewed a candidate from Microsoft in an objective C project who had brought their own keyboard that they had assembled (or soldered?) themselves. Three-ish hours pairing with someone who on paper seemed too bizarre to work out.
Best interview I ever conducted. Great hire. Never would have known if we hadn’t sat down to write software together.
Excel is so wild.
My mind was blown. I had thought, naively perhaps, that circular references in Excel simply created an error. But this data scientist showed me that Excel doesn’t error on circular references—if the computed value of the cell converges.
You see, when formulas create a circular reference, Excel will run that computation up to a number of times. If, in those computations, the magnitude of the difference between the most recent and previous computed values for the cell falls below some pre-defined epsilon value (usually a very small number, like 0.00001), Excel will stop recomputing the cell and pretend like it finished successfully.
A former coworker of mine made this and posted to our shared alumni slack: https://doyouneedatruck.autos/
It’s a very simple quiz that asks everything relevant about your situation and provides you an answer personalized to you. I can vouch that it’s actually 100% correct.
@alpha not to the best of my knowledge, no. Wouldn’t surprise me if there were but I have never heard of them after decades of exposure to this setting.
I’m not a LotR super fan by any stretch but I have read the hobbit twice, read LotR two or three years ago, and seen all the movies. If they do exist they are a super deep cut.
