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. We'll discuss the algorithmic tradeoffs behind LFU and compare different implementation strategies, ending with benchmarks in C++ and Rust.

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. The result is inconsistent calls and a feeling that marketing is not working. We will walk through the three places every local business needs to show up, plus the fourth place most owners ignore that quietly produces the warmest leads. **What to expect** Doors open at noon. 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. Service businesses, retail, home services, professional services, online owners building local presence, anyone serious about being part of the Columbus business community. **Not the right fit if** You are here to pitch the room or recruit for an MLM. **Details** * Second Monday of every month * 12:00 to 1:30 PM * Good Cafe Easton, 4400 Easton Commons, Ste 150, Columbus, OH 43219 * Order lunch and drinks at the counter when you arrive * Free to attend, RSVP required, space is limited **About the host** Rita Suzanne is a local marketing strategist and the founder of Local Marketing Method.
