LFU looks deceptively close to LRU: both caches evict the "least useful" item. We'll look at how the ordering rule affects data structure design.

Welcome, readers! Our June read is ***Endurance: Shackleton's Incredible*** ***Voyage*** **by Alfred Lansing.** A work of nonfiction, and one of the most astonishing survival stories in history, we follow Sir Ernest Shackleton and his crew after their ship is crushed by Antarctic ice. Stranded in one of the harshest environments on Earth, the men endure months of isolation, freezing temperatures, and near starvation—yet refuse to give up hope. Lansing brings their ordeal to life through vivid detail and firsthand accounts, capturing both the brutality of nature and the resilience of the human spirit. At its core, the story is a powerful testament to leadership, perseverance, and the unbreakable will to survive against impossible odds. Looking forward to discussing with everyone! We will meet at Zaftig Brewing Co in their event room in the back. We are welcome to bring in our own food, but **all** **drinks must be purchased at the bar.** Happy reading! 📖

Monthly working lunch for Columbus business owners. One specific topic, one to three actions you can run this week. You can be the best at what you do and still be invisible. If local buyers cannot find you, the phone does not ring. Marketing Monday Lunch + Learn is a monthly working lunch for Columbus business owners focused on building relationships, local networking, and local marketing. Every kind of local business welcome. No pitch round, no pressure, no upsell. **This month** Most local businesses pick one or two places to be visible and call it good.

Order lunch and drinks at the cafe counter or bring your own. You get real conversation with other local owners and a focused marketing lesson. You leave knowing people and with one to three actions to run that week. The room is reserved through 1:30 PM. **Who this is for** Any local business owner who wants clearer marketing direction and real local relationships.
