Hello friends!

I hope your week was awesome! I am so excited to be in your inbox today, because it is this newsletter’s FOURTH anniversary! I can’t believe it’s been this long, and I’m excited to keep this train chugging along. Also, happy Holi and Passover to those who celebrate them!

Something that interested me this week

It’s hard to believe, but this is the FOURTH anniversary of rendezvous with cassidoo!! Through ups and downs, it has been really fun putting this together for you, and I don’t plan on stopping anytime soon.

For those who have been around long enough, you know that I love doing raffle giveaways every year!

This year, I’ll be mailing out stickers to a few folks, plus:
- Name.com is giving up to 500 users a free domain name for all your website project needs when you use the code RENDEZVOUS at checkout. Choose from over 200 domain extensions, plus Advanced Security which includes a free SSL certificate! https://name.com/donutsdomains
- Twilio will be generously giving away some swag to 10 people!
- I’ve been advising a company called Polywork, who are building a new kind of network for showing what you do. They’re giving away 5 early access slots (plus access to their Slack community for product feedback) and the vanity username of your choice!

The domain names are first come first serve, but for everything else, it’s raffle-style! Please fill out this form by Friday at noon Central Time to get an entry!

I also want to say again and again: Thank you again for being here, it means a lot to me. It makes my day to hear from you and see tweets and messages from people that enjoy reading this, and seeing you share it with others.

Sponsor

This week’s sponsor is Mux!

If you’ve ever tried to do anything with video programmatically, you’ve seen the darkness. Acronyms that represent other acronyms, delivery best practices that change faster than JavaScript frameworks, and amazing tools… that come with decades of cruft and complexity. Video dominates Internet bandwidth and, for a lot of companies, engineering sprints.

Mux is the API to video that changes that. Instead of spending your time learning an entirely new vocabulary, you can just think about Video and how you want to use it. What Stripe did for payments and Twilio did for telephony, Mux does for video.

Take any video file or live stream and make it play beautifully at scale on any device, powered by magical-feeling features like automatic thumbnails, animated gifs, and data-driven encoding decisions. Spend your time building the experience and application that people want, not drudging through ffmpeg documentation.

Thanks Mux!!

Interview question of the week

Last week, I had you return the largest number from two integer arrays! There was actually a typo in the example, thanks all y’all who found it. I fixed it in the archive for those checking it out later! Awesome work Ashleigh, Jesse, Lucie, Timar, Leslie, Robin, Elliot, Dimitris, Sam, Giuseppe, Tobias, Tom, David, Leyan, Dhanush, Sridhar, Kartik, Aditya, Caroline, Amy, Michael, Damien, Manoj, Vanessa, ValeYellow46, Kyle, Maximiliano, Becker, Steve, Mark, Chris, Daniel, Jonathan, Ivana, Paul, Jay, Yosef, Karey, Shreya, Luciano, Max, and Ten!

This week’s question:
Given a string, return true if the string represents a valid number. A valid number can include integers, a ., -, or +.

Examples of valid numbers: “7”, “0011”, “+3.14”, “4.”, “-.9”, “-123.456”, “-0.1”

Examples of invalid numbers: “abc”, “1a”, “e8”, “–6”, “-+3”, “95x54e53.”

Joke

I went to a beekeeper to get 12 bees. She counted and gave me 13.
“Excuse me, you gave me an extra.”
That’s a freebie!

That’s all for now, folks! Have a great week. Be safe, make good choices, and thank you for being here!

Special thanks to Gabor, Stephen, Shell, IceSloth, Luna, Emad, Alaska, and Josh for supporting my Patreon and this newsletter!
