This morning, Sir Richard Branson went to space. Virgin Galactic did an impressive job, and the flight went off without a hitch, but this article isn’t about that; it concerns the much more significant threat our space travel poses. Our species is advancing technologically forward at an unprecedented rate, and that rate of change is also dramatically increasing. Even with all the advances since the Mercury and Apollo programs nearly five decades ago, we are still bound to earth as a species. From this May, our best speed record in space to date is only 1/20th of one percent of…


An open letter to the college chancellors across the country.

The News&Observer August 6, 2020

I was brought up with the belief that educators and academics were always a little smarter and wiser than the rest of us. During the last few months, that philosophy has been shattered! With the US Covid-19 death toll passing 160,000, it’s time we revisit returning to college. This week we’ve seen videos of campus parties with young people ignoring all the safeguards put forth by college administrators. …


Two weeks ago an executive I report to mentioned that they were going to post a leader board composed of peoples self reported Linkedin Social Selling Index (SSI) scores. As one of Linkedin’s first million users, you’d have thought I’d heard of this by now, but I hadn’t. Score are out of 100, and it is composed of four pillars, each with a value of 25 points. If you overachieve in any given pillar, you can’t earn more than 25 points; it’s a hard cap. The only way to beat the SSI, is to learn as much as you can…


For nearly a decade and a half, Myricom, a hot tech startup at the turn of the Millenium, measured success not by profitability, but by the percentage of the Top500 running its flagship Myrinet interconnect. Sure, we had to be profitable, but the CEO/founder was laser-focused on the penetration of his network into the fabric of supercomputing. Myrinet-2G dominated the list for several years, but by SuperComputing in 2009 (SC09) in Portland, it had become apparent that Myricom had lost the number one Interconnect position, possibly forever, to Infiniband.

Establishing a world record is one way of saying, “This is the best we can do as humans; now, let’s all try to beat it.” From Baseball, and the Guinness Book to the Olympics and Track and Field, we are continually striving to lift more, jump higher, or move faster. In business, the ability to react and adapt more quickly than your competitor has value. In Electronic Trading, like no other market, they can precisely assign a dollar value to that increase in speed. A trader can execute the same strategy on two systems in parallel, at the same time…


High Traffic Doesn’t Have to Mean Congestion

Many applications from biological to financial and Web2.0 utilize in-memory databases because of their cutting-edge performance, often delivering several orders of magnitude faster response time than traditional relational databases. When these in-memory databases are moved to their own machines in a multi-tier application environment, they often can serve 10 million requests per second, and that’s turning all the dials to 11 on a high-end dual-processor server. Much of this is due to how applications communicate with the kernel and the network.

Last year, my team used one of these databases, Redis, we then bypassed the kernel, connected up a 100Gbps…

As system architects, we seriously contemplate and research the components to include in our next server deployment. First, we break the problem being solved into its essential parts; then, we size the components necessary to address each element. Is the problem compute, memory, or storage-intensive? How much of each element will be required to craft a solution today? How much of each will be needed in three years? As responsible architects, we have to design for the future, because what we purchase today, our team will still be responsible for three years from now. …

A distinctive characteristic of our species, perhaps the most unique, and the one that has separated us from all the others, is the compounding effect of our technology. Each generation has added to our collective knowledge, improved our processes, and accelerated our development. Today we regularly craft complex products, with billions of internal components, from devices that are one hundredth the diameter of a blood cell. Regardless of how small technology enables us to shrink our creations, another issue that remains constant is that we still need to place our trust in this technology for it to make a difference…


Tesla Autopilot on the Highway

Yesterday during one of my many calls each week with my seventy-something mom, she mentioned that she might pass on going to her close friend’s 80th birthday party. When I asked why she said that the four and a half-hour drive up the Florida Turnpike was becoming too scary, she said that people are continually cutting her off, and it makes her very fearful. Mom hasn’t had an accident in decades, and she doesn’t have any of the usual scratches and small dents that often deface the autos of our greatest generation. Her vision is excellent, memory is intact, and…


Typical 12 GPU Mining Frame

When people hear I’m involved in digital currency, the next question inevitably asked is, can I still mine from home at a profit? There are several answers. If you want to mine for Bitcoin, the straight-up answer is no. Some large industrial miners have made it all but impossible to compete. First, they buy their mining rigs at a significant discount off the retail price. Second, they always have the latest most efficient mining rigs, often before they are generally available to consumers through exclusive deals with the manufacturers. Finally, their cost for electricity is nearly free or at most…
