This Month in Spring - January 2022

January 19, 2022 Josh Long

Hi, Spring fans! Happy new year! Welcome to another jam-packed, fun-filled, rock'em sock'em installment of This Month in Spring! How're you? I'm fresh off my three weeks holiday break! It's so good to be back. I've been busy over the break, working on updating my blog and on updating the Reactive Spring book. We just celebrated the 11th anniversary of This Week in Spring - I've been writing This Week in Spring every week without fail for 11 solid wonderful years. Crazy. I started writing it on the first Tuesday of January 2011, thanks to a wonderful idea from SpringSource co-founder and all-around good-guy Keith Donald (@kdonald). Thanks, Keith!

What a run! As always, I just wanna extend a heartfelt thanks to all of you who read (suffer!) my rambling writing every week. We've been lucky, as a community, to have presided over the most amazing and uplifting period in Spring and the JVM's history... This roundup has reflected that with incredible stuff happening all the time. Where there's smoke, there's fire. The many blogs, articles, podcasts, YouTube (and ever so occasionally Vimeo) videos, etc., are interesting in themselves, but they also signal interesting developments in the ecosystem, which is even more interesting! Rock on, community!

You know, even the number, the numeral itself - 11 - changes things. In English prose, it's customary to spell out numbers that are less than 10. So, "one," "two," etc. Some style guides include "ten," too. But 11, well, I can just write 11. Who's gonna stop me? The New York Times Style Guide? Too late, I already checked it!! That's one less grammar grievance, one less style snafu, if you will, to be found in this blog! You ever pop a zit, pay off a credit (or technical) debt, or clean your house and just felt this overwhelming satisfaction? Like Marie Kondo says, you gotta throw it out if it does not spark joy. And having to wrangle with the numerals for the number of years of this blog? Well, it definitely did not spark joy.

But you spark joy, my friends. Thank you again for making this work so valuable. Without community, there's no point in a community roundup, is there? You are the reason for the season (Spring)! So, as always, I'm happy to hear about the latest-and-greatest that you feel worthy of inclusion: hit me up anytime (@starbuxman) or!

And now, without further ado, let's get to this roundup!
