I’ve encountered this in my career, at many places. Sadly, early in my career, I participated in some of this. You are a zealot for a particular form of tech if you can see it do no wrong, and decry reports of issues or problems as “attacks”. You are a zealot against a particular form … Read more On technology zealotry
I’ve written about approved vendors and “one throat to choke” concept in the past. The short take from my vantage point as a small, not well known, but highly differentiated builder of high performance storage and computing systems … was that this brand specific focus was going to remove real differentiated solutions from market, while … Read more What reduces risk … a great engineering and support team, or a brand name ?
My new day job has me developing considerably less code than my previous endeavor, so I like to work on problems to keep these particular muscles in steady use. Happily, I get to do more analytics than ever before, so this at least is some compensation for the lower amount of coding. When I work … Read more On hackerrank and Julia
If you don’t know what I am talking about here, that’s fine. I’ll assume you don’t do hardware, or you call someone else when there is a hardware problem. If you think “well gee, don’t we have lspci? so why do we need this?” then you probably have not really tried to use lspci to … Read more pcilist: because sometimes you really, really need to know how your PCIe devices are configured

So yeah, this broke my MySQL instance for … Read more That was fun: mysql update nuked remote access
It is a short read, and you can find it on arxiv. They tackled an integration problem, basically using the code to perform a relatively simple trajectory calculation for a particular N-body problem. A few things lept out at me during my read. First, the example was fairly simplistic … a leapfrog integrator, and while … Read more An article on Rust language for astrophysical simulation
So there I was, trying to use a serial port on a node which was connected to a serial port on a switch. Which I needed to properly configure the switch. So I light up minicom and get garbage. Great, a baud rate mismatch, easily fixed. Fix it. Connect again. I get the first 10-12 … Read more strace -p is your friend
Systemd has taken the linux world by storm. Replacing 20-ish year old init style processing for a more legitimate control plane, and replacing it with a centralized resource to handle this control. There are many things to like within it, such as the granularity of control. But there are any number of things that are … Read more I don't agree with everything he wrote about systemd, but he isn't wrong on a fair amount of it
