Real science does not care about your narrative

In the soviet union, early in the 20th century. a political narrative was born.  In it a pseudo-scientist, really, an activist, named Trofim Lysenko decided that it was politically incorrect to study or apply genetics.  He insisted that Lamarckism was the proper, politically correct theory.  And thus a narrative was…

Relearning Maxima (Macsyma)

In undergrad (Stony Brook), I had a math teacher (numerical methods class) who talked about this package he used in his research.  Macsyma was a symbolic math package, sometimes called a computer algebra tool.   Of course, seeing the likely utility of this in some of my courses (I am still…

Backing up decades of data

This is a tale of backing up data.  To date, I have a small-ish 28TB server at home running zfs (finally) on debian 11.5.  This is my local backup target, and I take snapshots of my other systems over to it. Most of my other systems have 1-2TB of…

On medical device company and insurance complex (in the US)

Performance optimizing python for #HPC ...

It sounds strange, as python is not, by any stretch of any imagination, a high performance language.  If you have a great deal of data you are working with, like I do for my $dayjob, and you need to performance optimize your code, you have a few specific options for…

Much ado in the [HPC] world

I've been relatively quiet here on this platform, apart from my wonderful canine son.  I plan to rectify this. At the end of 2022, we have a world where Intel is on the ropes in HPC, it can't deliver on a reliable schedule.  We have AMD ascendent, and rightly so,…

On recruiters, and others

I get recruiters sending me what amounts to obvious spam.  The most recent one was for a "life changing experience".  At the employer I left to join current day job. Others use search terms like HPC.  And they see me in their lists.  So they send me their invitations to…
