Hey friends!
Happy November! I hope you ended your October with a bang. Between GitHub Universe and Halloween, mine was particularly fun and busy this year.
Let's gooo!

Something that interested me this week
Phew y'all, I was in San Francisco for a LONG time for GitHub Universe, and I'm so happy to be home! I did a little meta round-up vlog about it while also recapping my newsletter if you want to see some behind-the-scenes. It was a really good time podcasting and keynoting and building keyboards (which, btw, you can buy one of the exclusive kits if you want), and it was also so much work pulling everything together. I'm happy it happened. I'm happy it's over. Ha!
Halloween was a cute one, my three-year-old is finally old enough to trick-or-treat and understand what's going on, which was a blast! And, because Mariah Carey said so... I did indeed set up my Christmas tree today.
Also, if you're in the United States: make sure you vote this week!!

Interview question of the week
Last week, I had you swap Halloween costumes! Y'all did a spooktacular job Ten, Paul, Kyle, Trey, Thulasi, Alison, Rhett, Amine, and the smarties in the Ruby Users Forum!
This week's question:
Given a chronological log of local "HH:MM" timestamps from the night daylight saving time ends, return the actual number of minutes between the first and last entries. The log contains a consecutive pair that reveals the clock’s one-hour rollback.
Examples:
elapsedMinutes(["00:50", "01:10", "01:50", "01:10", "02:10"]);
> 140
elapsedMinutes(["01:55", "01:05", "01:25", "01:40"]);
> 45

Howdy friends!
I hope you had a great week! Mine has been SUPER busy with final rehearsals and preparations for GitHub Universe this next week, and I'm excited to welcome devs to the big event online and in person in San Francisco. Until then... let's boogie.

Something that interested me this week
This week, truly... I have done nothing but GitHub Universe work. I'm writing this from inside GitHub HQ in San Francisco, between rehearsals with execs and helping wrangle swag + exciting goodies for the event ahead. It's been SO much work. I'm really grateful to be on a team that is so hands-on and cares deeply about making this a great experience for developers! I'm obviously biased because I work here, but if you have the time, register free online on the GitHub Universe website! You'll see a familiar face (me) on the stream a few times!

Interview question of the week
Last week, a ghost infected your keyboard and you had to parse how it messed up your typing! Spoooooky answers (that were quite clever!) were great from Stephen, Dani, Omer, Michael, Trey, David, Kyle, Greg, Rhett, Thulasi, Ricardo, Josh, Christian, Debopam, Ten, and the fine folks in the Ruby Users Forum!
This week's question:
Each person at a Halloween party has exactly one costume, but they’ve been shuffled: costumes[i] is the index of the person who owns the costume person i is wearing. Return the minimum number of swaps between any two people needed to give everyone their own costume.
Examples:
> halloweenSwap([0, 1, 2, 3])
> 0
> halloweenSwap([1, 2, 0])
> 2
> halloweenSwap([4, 3, 2, 1, 0])
> 2
> halloweenSwap([2, 3, 4, 0, 1])
> 4
