Intel’s AI Ecosystem and AI PCs | Gestalt IT Rundown: January 3, 2024

January 3, 2024

Intel has been stepping up their game in the AI ecosystem. Both Meteor Lake and the latest Emerald Rapids Xeon SP processors are being positioned as edge computing powerhouses. From running AI workloads on end-user systems to providing support for AI frameworks throughout the infrastructure Intel is looking to break into the market that is dominated by big players right now. Perhaps we can take a quick look at why Intel sees so much promise here but also the hurdles they’ll have to clear to stake a claim.

Your IT Security Policy Needs to Be Followed

January 2, 2024

IT security policies are aspirational goals because they have so many exceptions. The difference between being hacked and being safe could come down to one employee. In this episode, Tom Hollingsworth sits down with Jasper Bongertz and Brian Knudtson to talk about how security polices are inherently fragile and can cause people to have more faith in them than they should. Also discussed is how people are not always the problem in these situations and how companies can do a better job of crafting documents that reflect real-world applications of protection.

Meet Mike Bolitho, Wireless Engineer
