I learned today, of the HPE Greenlake flex system. It has a nice infographic which describes it. What struck me, was that this was a model very similar to something I had worked on in 2014-2015, that I had been trying to raise capital to execute against, at Scalable Informatics (RIP). The question the VCs … Read moreWhen you see someone deploying a business model very similar to one you had developed on your own …
We’ve seen issues in the past, with massive flooding in Thailand, wreaking havoc on critical components in supply chains. The subsequent demonstration of the basic economics laws of supply and demand did not make users or vendors very happy. This arose due to a significant over-allocation of one small geographical region to a critical component … Read moreLength and complexity of supply chain as a risk factor for HPC and storage
So I’m playing with Julia in my off time to get more proficient with it. Doing some “simple” things in preparation for the work I want to do.

Quick post … I’m excited to note that I’ll be joining Cray, the preeminent HPC company, to help develop solutions for HPC customers to consume supercomputing resources in the cloud. I start the week of the 22-April. More soon, but I gotta say, I’m quite excited about this!
So I saw this , and yes, it is quite funny. There’s a discussion of this at HackerNews, which seems to follow a number of conventional pathways. Most of them missing the obvious implied humor.
A short note – today was my last day with Joyent. They are a wonderful company, building great things. Excellent technology, and technologists. I wish them nothing but success. For the immediate future, I’ll be working on consulting projects, as well as looking for the next great opportunity within high performance computing, storage, cloud. I’m … Read moreOnward and upward in #HPC
Yeah … this was a fun one. Because I only recently started using a holistic VM management/control plane for my home machines, I didn’t notice that I had 2 VMs of the blog running. I was doing some surgery to fix something, then tailed the logs … and didn’t see the traffic. Took me a … Read moreNote to self: have only one blog VM running
