So … I’ve had this blog since 2005. I installed it from original sources. And WP made upgrades in the 2.x time frame, quite painless. Or so it seemed. Slowly, over time, some configuration/settings/whatever got out of whack. And with the last update, from a system originally installed in final form in 2013 or so, … Read more Well … that was fun
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 am a fan of the Julia language. Tremendously powerful analytical environment, compiled, high performance, easy to understand and use, strongly typed, … there’s a long list of reasons why I like it. If you are doing analytics, modeling, computation in other languages, it is definitely worth a look. Think of it as python, compiled, … Read more Interesting post on mixed integer programming for diets … that has some hilarious output
Repo is here: https://github.com/joelandman/rzf. There’s a lightning talk to go along with it, and I’ll make sure I can get it together for this as well.
These are a collection of (MIT licensed) tools I’ve been working on for years to automate some of the major functionality one needs when setting up/using new machines with lots of disks/SSD/NVMe. The repo is here: https://github.com/joelandman/disk_test_setup . I will be adding some sas secure erase and formatting tools into this. These tools wrap other … Read more Disk, SSD, NVMe preparation tools cleaned up and on GitHub
I’ve not heard of aria2c before today. Sort of a super wget as far as I could tell. Does parallel transfers to reduce data motion time, if possible. So I pulled it down, built it. I have some large data sets to move. And a nice storage area for them. Ok. Fire it up to … Read more Aria2c for the win!
This was making the rounds last week. Oracle seems to have a leak in its process, creating labels that trigger event notifications for people, for their packages. Solaris was decimated. More details at the links and at The Layoff. Honestly I had expected them to reach this point. I am guessing that they were contractually … Read more Oracle finally kills off Solaris and SPARC
There are a set of modules in the Perl universe that I’ve been looking for an excuse to use for a while. They are the MCE set of modules, which purportedly enable easy concurrency and parallelism, exploiting many core CPUs, and a number of techniques. Sure enough, I had a task to handle recently that … Read more Finally got to use MCE::* in a project
Waaaay back in grad school in (mumble) late 80s/early 90s (/mumble), I started using Unix in earnest. Back then, my dad shared some funny Unix error messages which were double entendres … often quite entertaining, as the shell was effectively playing the straight man in a comedy duo. Without intentionally doing so (of course). Nowadays, … Read more More unix command line humor
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 ?
