Hellloooo!
Can you believe it's December already? I truly cannot. Time is so weird. Let's kick off the month with a bang!

This past Thanksgiving week was full of very welcome family time! I had such a packed week of toddler-wrangling, eating with family, watching the new Wicked movie, and just being more offline than usual.
That being said, I did get back into blogging a bit more, this week! I wrote about:
That last post there is my first in my newest Blogvent series, where I'll (try to) write a blog post every day for December!
The fastest way to build AI apps.
Writer is the full-stack generative AI platform for enterprises. Quickly build and deploy AI apps with Writer AI Studio, a suite of developer tools fully integrated with our LLMs, graph-based RAG, and AI guardrails. Use Writer Framework to build Python AI apps with drag-and-drop UI creation. Our API and SDKs allow you to integrate AI into your existing codebase.
Start building with AI Studio.
Last week, I had you organize a family meal! I fully messed up my own examples for the question and I apologize for that. Blame my sleepy brain writing code at that hour. Good catch to the folks who figured it out and worked around it! Good work smarties Ender, Yosola, Austin, Phillip, Amine, Andreas, Ten, and Eric!
This week's question:
Santa is conducting his daily roll call for the reindeer, but the printer has mistakenly printed all their names backwards. To take attendance properly, he urgently needs a tool to reverse the reindeer names and put them in alphabetical order! Can you help Santa?
Example:
rollCall(["yzneT","ydissaC","enimA"])
["Amine","Cassidy","Tenzy"]
rollCall(["rennuD","nexiV","recnarP","temoC","neztilB","recnaD","diduC","rehsaD","hploduR"])
["Blitzen","Comet","Cupid","Dancer","Dasher","Donner","Prancer","Rudolph","Vixen"]
rollCall(["A","B","C"])
["A","B","C"]

Hey friends!
Happy Thanksgiving week, Americans! I hope you have some fun plans. For everyone else, I hope you also have fun plans, even if they don't involve stuffing your face with good food. Shall we dance?

I spent the whole week at Microsoft Ignite! It's a giant Microsoft conference that I had never been to before, and it was really interesting. It's more IT-oriented than developer-oriented, which I'm not really used to, and I learned a bunch about what these highly technical people do (who don't often code, what a concept).
I gave a few talks (sadly none were recorded, BUT you can hear my voice during the keynote on the conference homepage at 2:07:36 and some other parts if you really want to, ha), manned the GitHub booth, and had some really fun conversations with attendees and my teammates. It was a good time, but I'm definitely tired and looking forward to a holiday week to rest up!
Volv is a Snapchat-backed social news app that consolidates the most important, viral, and interesting content from around the web into 9-second stories that you can just scroll through like social media. Users call it “TikTok for smart people”, since they use Volv instead of TikTok and Insta to discover quality content that they would’ve never read otherwise. So far, users have read 60 million stories on the Volv app!
Here’s a code you can use to get Volv Premium free for a month: VOLVRC

This week's question:
You're organizing a family meal. Given a list of dishes and their respective preparation times, return the minimum number of hours required to prepare all dishes if you can cook up to two dishes simultaneously. If a dish takes longer than the remaining time of the current hour, it will be moved to the next hour.
Examples:
// Using number of minutes for prep time
mealPrep([120])
2 // one single long dish
mealPrep([30, 30, 30, 20])
1 // multiple shorter dishes
mealPrep([30, 25, 45, 30, 60, 15])
3 // many dishes with varying times

This week I'll be speaking at Microsoft Ignite (which you can watch for free online!) and I'm excited to meet some more coworkers in person and show them the joys of Chicago food!
Besides that... I mentioned it before, but I have really been having fun with Bluesky as a social network. It's been really lovely having a simple feed of just people that I follow, and other lists of feeds I can follow (for example, the Good Lunch feed), and not have the algorithm decide how I browse (which makes me want to update my human curation blog post I wrote a little while back). Outside of the network itself, I recommend reading about the AT Protocol, which is how Bluesky works under the hood. It's really interesting!

Working with auth shouldn’t feel like coding with 🧤oven mitts. You really need to try Stytch.
They’re Auth0 on steroids. Beyond hosted widgets, Stytch gives you full control with options for pre-built UI, headless SDKs and comprehensive backend SDKs and APIs for authentication and authorization. Plus, it comes with the latest in fraud and risk prevention—without relying on CAPTCHA and simple network-based protections.
Stytch also supports dedicated data models for consumer and multi-tenant B2B applications, so you aren’t forced to code around the “black box” of Universal Login. All the acronyms — MFA, SSO, RBAC, SCIM – are just an API call away.
Try it free and see why Mintlify, Groq, Hex, Orb, Zapier, and Replit have switched to Stytch.

This week's question:
Given an array of integers representing the stock prices of a company in chronological order, write a function that determines the maximum profit you can achieve by buying and selling the stock once. If no profit can be made, return 0.
Example:
> maxTheStock([7, 1, 5, 3, 6, 4])
> 5 // (buy at 1, sell at 6)
> maxTheStock([7, 6, 4, 3, 1])
> 0 // (no profit possible)

Howdy y'all,
I hope you're staying safe and healthy with folks you care about this season. This was a really intense week for a lot of people, including myself, and it's times like these where I'm grateful for the little things that make us happy. Let's learn!

Sooo, elephant in the room, the U.S. Presidential election happened this week. The results were not what I wanted, and I don't really want to talk about how sad I am about it. I hope that if the results are also not what you wanted either, you're doing okay. "Okay" is such a... flimsy word to use, and it's really hard to come up with another one. But I genuinely, really hope that you are doing okay, and have a community that you can lean on for support, and you can be that support for others.
...besides that, I've now been at GitHub for two months, I reflected on falling asleep in a driverless car, I've been really enjoying Bluesky as a social network, and I've been cuddling my 18-month-old who has recently learned how to count to five in English, Spanish, and Korean, which is very exciting.
Curious about which authorization model is best for your app? The answer is probably "all of them."

Plus, a technical comparison of Google's approach with Oso's Authorization as a Service, highlighting the similarities and key differences. Walk away with the tools you need to make an informed decision about which approach meets your app's permissions needs!

This week's question:
Given a list of integers representing the heights of buildings, return the maximum number of buildings that can be seen when looking from the left. A building can see another building if it is taller than all the buildings to its left. The height of the tallest building is included in the count.
Examples:
seeBuildingsLeft([1,2,3,4,5])
5
seeBuildingsLeft([5,4,3,2,1])
1
seeBuildingsLeft([3,7,8,3,6,1])
3

Given an array of strings, group the anagrams together.
Example:
groupAnagrams(["eat", "tea", "tan", "ate", "nat", "bat"])
[["eat","tea","ate"],["tan","nat"],["bat"]]
groupAnagrams(["vote", "please"])
[["vote"],["please"]]
groupAnagrams(["debitcard", "badcredit"])
[["debitcard", "badcredit"]]
