Tried 20 Billion Integers tonight with Pharo Smalltalk. This took more than the physical memory I had available. It took a long time to run, but the following code finished after 40 minutes or so.

Blog: 10 Billion Integers Walk Into an Array

I wrote this blog in October last year, and it has been my top blog for the past year based on number of views and reads. 🤷‍♂️

Cup half full here.

The world's problems are too numerous for any one person to solve. Pick one or two and solve the 💩 out of them. Support and advocate for those who are working hard to solve other problems you care about. Thank you for doing what you do to make the world a better place for all. 🙏

I'm back home from #dev2next and am writing my first blog in over a month. I only wrote one blog in September, mostly because I was busy preparing and travelling to two developer conferences. Stay tuned!

So long Colorado. Good times had and memories made at #dev2next this year. Thank you @dev2next.bsky.social and @venkats.bsky.social ! 🙏 Below was my new sighting at Garden of the Gods this trip. Balanced with the force is this rock. An inspiration. Balance we must all find. ⚖️

Great talk! Looking forward to using it in my projects to replace some awkwardness in my existing projects and get real immutability.

It was unplanned and unrehearsed that Vlad wore a #Java t-shirt, and I wore an Eclipse Collections Categorically t-shirt at our talk today. A fun coincidence given the topic of the talk. 🤷‍♂️

Join @zakhav.bsky.social and myself tomorrow at 10:45am in Salon FGH to learn why and how we've written #Java code with #EclipseCollections for the past 21 years.
