A closer look at two newly announced Intel chips

Our initial look at Intel’s Architecture Day focused on the new Xeons and IPU processors. Now we’ll get into the fine details, as well as look at other upcoming technologies.Sapphire Rapids Intel’s upcoming next-generation Xeon is codenamed Sapphire Rapids and promises a radical new design and gains in performance. One of its key differentiators is its modular SoC design. The chip has multiple tiles that appears to the system as a monolithic CPU and all of the tiles communicate with each other, so every thread has full access to all resources on all tiles.To read this article in full, please click here

Tech Bytes: DDOS and State Exhaustion With NETSCOUT – Updated

Its not widely that DDOS attacks also cause damage from state exhaustion in devices. A recent study why Netscout surprised me that many engineers are aware of overload bandwidth or routing devices but give less considerations to state exhaustion in application aware devices.

How IT Pros Learn Online In 2021

I surveyed 53 IT professionals about online IT training in August 2021. Most of the folks I interact with are networking & cloud infrastructure professionals, and the answers reflect that. 53 responses isn’t enough to draw hard and fast conclusions from, but I still believe there are interesting trends & individual comments worth thinking about.

By the way, if you’d like to submit your own responses, I left the survey open. I told Google Forms to not collect email addresses, so your responses are anonymous.

Hedge 97: Low Context DevOps

Language is deeply contextual—one of my favorite sayings from the theological world is if you take the text out of its context, you are just left with the con. What does context have to do with development and operations, though? Can there be low and high context situations in the daily life of building and running systems? Thomas Limoncelli joins Tom Ammon and Russ White to discuss the idea of low context devops, and the larger issue of context in managing projects and teams, on this episode of the Hedge.

The Huge Payoff Of Extreme Co-Design In Molecular Dynamics

When money is really no object and the budget negotiations involve taking a small slice of your personal net worth of $7.5 billion out of one pocket and putting it into another, and you have the technical chops to understand the complexities of molecular dynamics and have a personal mission to cure disease, then you can build any damned supercomputer you want.

The Huge Payoff Of Extreme Co-Design In Molecular Dynamics was written by Timothy Prickett Morgan at The Next Platform.

Linux turns 30

Something happened back in 1991 that dramatically changed the future of computing. Linus Torvalds, a Finnish-American software engineer, released the Linux kernel and the second version of the GNU General Public License (GPLv2). A good portion of the technology we use today would not be what it is had this not happened.It all started on August 25th of that year when Torvalds announced in a usenet post that he was working on a free OS and that it would be ready within a few months. He also said it "won't be big and professional like gnu," but that wasn't exactly how things turned out!The GPL The beauty of the Gnu GPL was that, instead of restricting what users can do with the Linux kernel, it maximized their rights. Richard Stallman, GNU founder, referred to these rights as the "four freedoms." They include the freedom to run, copy, study/improve and distribute. This was akin to turning the function of a license inside out.To read this article in full, please click here
