More unix command line humor

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, […]

On hackerrank and Julia

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 […]

What is old, is new again

Way back in the pre-history of the internet (really DARPA-net/BITNET days), while dinosaur programming languages frolicked freely on servers with “modern” programming systems and data sets, there was a push to go from a static linking programs to a more modular dynamic linking. The thought processes were that it would save precious memory, not having […]

That was fun: mysql update nuked remote access

Update your packages, they said. It will be more secure, they said. I guess it was. No network access to the databases. Even after turning the database server instance to listen again on the right port, I had to go in and redo the passwords and privileges. So yeah, this broke my MySQL instance for […]

An article on Rust language for astrophysical simulation

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 […]

Brings a smile to my face … #BioIT #HPC accelerator

Way way back in the early aughts (2000’s), we had built a set of designs for an accelerator system to speed up things like BLAST, HMMer, and other codes. We were told that no one would buy such things, as the software layer was good enough and people didn’t want black boxes. This was part […]

A new #HPC project on github, nlytiq-base

Another itch I’ve been wanting to scratch for a very long time. I had internal versions of a small version of this for a while, but I wasn’t happy with them. The makefiles were brittle. The builds, while automated, would fail, quite often, for obscure reasons. And I want a platform to build upon, to […]
