I once thought that Facebook was Usenet in a prettier/more user friendly package. Twitter is simply horrible. You can make a completely innocuous comment on a current conversation, and someone will barge in, exhort in a hyperbolic an

I find that some of my professional colleagues are some of the most toxic posters. I've got many active filters in place, but in some cases, I've simply muted/blocked some of them. Done the same on Facebook, which I use most

Yes. Quite a few tools and products at $dayjob are Perl with active development, multiple large scale revenue numbers attached to them. I use perl daily in my work on supercomputers and hpc systems. My code helps configure and control them

Wait ... but ... why? (in jest) I understand why, though some of us think of decaf "coffee", much the same way others view white "chocolate". At some point, the thing you modified it to be, isn't representative of

Been out of physics for 23 years, but, yes. Without the studio laugh track, and generally humor. Also add in lots of politics.

A buddy of mine in grad school (he was an HEP postdoc), once told me (computational condensed matter), that I was working in the dirt left over from the "real" physics. He was a nice guy, but enjoyed ribbing me a bit. That said,

About 2 years ago, I shared a zpool between Linux, FreeBSD, and SmartOS/Illumos. It generally just worked, no matter where the zpool was created from. People warned me about not enabling specific features, so I simply used defaults

I got into the habit of documenting each file with a file.meta that I could view later on. I did binary dumps in the past because ascii dumps (remember, 90s) were far more time/space expensive. HDF wasn't quite an option then, ei

Short answer: Yes, my 30 year old Fortran code runs (with a few minor edits between f77 and modern fortran), as did my ancient Perl codes. Watching the density functional theory based molecular dynamics zip along at ~2 seconds per time step

Again, assigning blame to a single party is simply incorrect. It shows bias. From today[1]. And previous reporting on this identifies the party[2]. Not the GOP. Fraud occurs[3], and it is not only from one particular party or group. Th

Not for nothing (and feeling somewhat old for remembering this) but lyrics from a song from the late 80s come to mind[1]. "That those who know what's best for us Must rise and save us from ourselves" It was on a playlist I wa

Competition tends to force organizations to evolve to meet the threat. That is, unless some government intervenes in the market, distorting the effect. Then you get a distorted market with inefficient allocation of resources. Seems to hap

I hate to say it, but it looks like this has been the case for a while. Look at the history of gerrymandering. What I see is something that could potentially change the basis of trust for elections in a positive way. It won't be perf

Hmm ... could be some of the other tooling around it. Right now I can't get XLSX to talk reliably to DataFrame. I rigged up some tests for 10, 100, 1000, ... points and performance above about 500 points fell off a cliff. I should lo

I gave a talk at some kx/kdb usergroups[2], and definitely saw more than 12 people there. There were hundreds. Its not a trivial language to learn, you have to be ok with very terse languages in general, and ok using the language as a

I've run into an application, used for monitoring, that had that exact type of bug, albeit not with a dot file. A customer of my old business had built a little monitoring system for their compute nodes mounting a parallel file system.

I've had terrible customers when I ran my old company. I tried to ignore their behavior and focus upon being a worthwhile group for them to deal with. They tended to share a number of features. 1) great promises of future business if

This is due to the non-associative nature of FP. (a+b) + c != a + (b+c). I disagree that the "axiom" as stated is fundamental. My main argument with it is that I don't see an easy way to go from the axiom to usable theorems

Common views of QM are derived from various interpretations, not basic axiomatic statements. This article discusses some work in approaching QM from an axiomatic formalism.

(really not sure why this was down voted ... it is a good comment) Thanks. I'm aware of others struggles. I figure that my story could be a cautionary tale for some, and others may take lessons from it. When I say in other fora, neve

We had a customer that POCed on our systems, then bought some crap from HP + one of the SSD card vendors in 2013. They then called us up in 2014 and asked to pay us to help them achieve the performance they saw on our system, on their 5x a

Excellent post. I messed up my back a few years ago on a long trip. Messed up my workout routine. Just got it fixed a week before Covid.

Thanks! I've gone to visit sites and heard a few people whispering near me "its the scalability.org guy". Blew me away. I still write, albeit less frequently, and I have to keep to a narrower range of topics.

Not all of it. I blog here[1]. The post where I talked about the end is here[2]. Note the 'laws' I quote at the end of the post. My first post is here[3]. There I talk about the HPC market, accelerators, and some of our plans
