This week was a long week of being busy at work and kind of avoiding the chaos of news as much as possible here in the United States. I finished reading Yumi and the Nightmare Painter (it was excellent!!) and The Dip (it was short and decent, and honestly probably could have been shorter), started reading Babel, and spent good quality time with my toddler (we started swim lessons! So cute!). I am kind of falling behind on blogging these days and hope to get back into the swing of things sooner rather than later, so this is me saying it: I will write something this week!

Y'all this week was a LOT. I traveled to Seattle to do a team offsite for work, which was awesome! I hadn't been in one room with my whole team before, and it was so nice to get to know each other better, and plan out the next few months together.
But then... I got norovirus. My word, it was horrible. Luckily though it was relatively short, about 24 hours of... you know what, you can look up what the symptoms are, I'll spare you the details. But anyway, I'm thankfully better now, home in Chicago, and having some fun reading Yumi and the Nightmare Painter for the U.S. holiday weekend.

This was a busy first full week back at work! There was a bunch to catch up on, and my brain did not feel fully... awake.
But, it was good seeing coworkers again, doing a livestream about GitHub Copilot, planning some side projects, making some minor edits to my website, and I wrote some blog posts!

This week was full of wrapping things up and starting things fresh for the new year!
I wrote up my annual end-of-year recap, redid some small parts of my website, took down our Christmas tree, and ate a whole lot of leftovers. It was really good to have this period of time to recharge and get ready for the new year full of work (and not-work)!
No sponsor this week, happy new year!! Consider supporting one of these awesome organizations!
Last week, I had you get the day of the week for New Year's Day of a given year. Some of you kinda cheated with the JavaScript Date object but I'll give you a pass, ha!

This week's question:

Hey friends!
Wow, 2024, we're wrapping it up! It felt so fast and so slow, all at once. I hope you end the year on a note you're pleased with. Let's do it!

I finished writing my posts for Blogvent this past week! In case you missed it, it's an "advent calendar" of sorts that I started doing to blog daily in December. Here's my wrap-up post of all of the blogs I wrote this year! If you're on Bluesky, there's a hashtag where you can see others who participated as well. Blogging isn't dead!
It's really hard to believe that 2024 is ending already. It was a really big year of changes for me personally and professionally (...I will probably blog about it, heh), and I'm excited for more in 2025.
So, that being said... SEE YOU NEXT YEAR! Heheheheh.
No sponsor this week, but here's a few wonderful non-profits who could use your support as we wrap up the year:
Last week, I had you count perfectly round cookies! You all seem to like cookies. Me too. Great work Mac, Muhammad, Leyan, Neha, Ashish, Amine, John, Ten, Kyle, Kriszti, Mazen, Vincent, and Ricardo!
This week's question:
Given a year, return the day of the week for New Year's Day of that year.
Example:
> newYearsDay(2025)
> "Wednesday"
> newYearsDay(2024)
> "Monday"

Hey friends!
I hope you had a good week! Mine was PACKED with launches at work, and I'm really excited to chill with my family for Christmas this week. Until then, let's boogie!

Whew, this week we had some pretty dang big launches at work and I am so glad they are out in the world now! The main big ones were that we made GitHub Copilot free (!) and that we added OpenAI's o1 model to paid Copilot plans. For the latter, I got to write the announcement post and be a little cheeky on the official GitHub blog, which was fun for me.
Also, I was a part of a livestream panel discussion about the state of JavaScript, if you want to check it out!
And at last, outside of all that, I have been keeping up with my daily blogging for Blogvent! Here's the posts I wrote this week:
Writing daily is a little stressful, but at the same time, it keeps getting easier, the more I do it. I'm glad to have gotten this far with it!

This week's question:
At the Magic Cookie Factory, cookies are baked in factorial quantities. A cookie is "perfectly round" if its size ends with a zero. Write a function to determine how many perfectly round cookies will be made when baking with n! ingredients.
Examples:
countPerfectlyRoundCookies(5)
1 // 5! = 120, which has 1 trailing zero
countPerfectlyRoundCookies(10)
2 // 10! has 2 trailing zeros
countPerfectlyRoundCookies(100)
