John McCool liked thisJohn McCool liked thisIt's official! On Saturday, May 2nd, I graduated with my Doctor of Nursing Practice, with a focus on Advanced Public Health Nursing, from Rush University. My focus is on system-level transformation, specifically the gap between clinical care and the daily lives of the 75% of US adults living with chronic conditions. With $4.5T spent annually on chronic care management, I believe nurses are uniquely positioned to address a number of challenges and look forward to being part of this work. Shout-outs to my professional alma mater Cisco, where I learned it was indeed possible to change the way the world lives, works, plays, and learns, and the Cisco CAP team who taught me how to marshal dynamic, cross-functional teams and refocus existing resources to solve previously intractable problems. I'm excited to apply these lessons—and your undaunted perspective—as I take this next step in advancing public health.

John McCool liked thisJohn McCool liked thisI'm excited to share some news! Today is my first day on the job as the new head of product and corporate communications at Intel. I’m incredibly enthused and energized by this opportunity. Intel is a company I’ve long admired and aspired to join. To me, it represents an industry stalwart and a national treasure. I’m also honored to join a company with such strong leadership team and to be working on Annie Shea Weckesser's marketing and comms team. She is a leader I’ve similarly long admired and aspired to join. More than anything else, I think we have a special opportunity at Intel to tell a powerful story about reinvention at a unique moment in time. The trends in tech and AI are lining up for Intel to be successful, and its success is so important to the US and the world. I simply can’t wait to tell this story!

John McCool liked thisJohn McCool liked thisIt is not everyday that you get to hang out with so many Google legends at the same table. The #TPU 8t/i launch party at #GoogleCloudNext made it possible this week!! It was a real honor to share the table with Urs Hölzle Jeff Dean Partha Ranganathan Rich Sanzi Bill Jia Ankur Jain, while Amin Vahdat was unveiling the TPU 8 family. The combined Google years at that table was more than 100 ... so many of the fundamental Google technologies that today's Google is built on also originated with them !!! I was definitely #FeelingLucky 🙏🏼

Ericsson supported Sabinal Energy with enterprise 5G with centralizing SCADA and delivering cloud-managed wireless WAN. They also gained: ✔️ Bandwidth of up to 500 Mbps in remote offices ✔️ Sub-40 ms latency ✔️ Centralized control through NetCloud As Sabinal’s VP of Infrastructure put it: “Ericsson’s enterprise 5G solution was a game-changer for us.” This is the kind of impact that inspires me to keep building the future of enterprise networks.

From 5G Hangover To AI Monetization: Broadcom’s Telco Playbook - @Evan Kirstel, Special to Technology Reseller News - Interested in being a guest? Email us at admin@evankirstel.com (https://lnkd.in/gsazi34c) - Read more from Evan (https://lnkd.in/gWSQjYqj) Telco’s growth model is broken. Here’s the blueprint to fix it. 5G returns are under pressure. Hardware costs keep climbing. And operators are drowning in complexity they can’t monetize. We sat down with VMware by Broadcom leaders to cut through the noise and what emerged is a sharp, actionable roadmap for what comes next. Three big shifts every telco leader needs to understand: **1. The mobile core is your highest-leverage asset right now.** Not the edge.
