Working with a variety of AI models (Claude, Grok Build, various locally run models) and agents, I am scratching an itch. When people deploy python and perl code, they have to either export their entire environment, or build a container. T

Look for llmfit on github. This will help with that analysis. I've found it reasonably accurate. If you have Ollama already installed, it can download the relevant models directly.

Thoughts on disabling ad blockers, subscription requests for sites, and the economic model underlying much of the internet these days.

I noticed the comments pointing out that TDP is a marketing number, and max power draw for this part can be higher. The cooling seems to have been inadequate. A rule of thumb I use for cooling is, you can rarely have too much. You should

I recall that while I was at SGI. Many of us within SGI were strongly against the move to sell this off to Sun. We blamed Bo Ewald for the disaster to SGI that this was, the lack of strategic vision on his part. We also blamed the idiots

Not true by any stretch. I've used komodo[1] for more than 2 decades as a debugger in Linux, Mac, and Windows. More recently VSCode on all 3, for debugging. Definitely not a dead language. A mature and stable language, which won&#x27

I have perl code I wrote in 1992 that still works properly, without changes. The binary executables have changed ISA from MIPS 4 to x86_64, and are compiled fortran (gfortran). There's even a switch I use to be able to read the large

At a previous job, I regularly worked with dfs of millions to hundreds of millions of rows, and many columns. It was not uncommon for the objects I was working with to use 100+ GB ram. I coded initially in Python, but moved to Julia when

This is my current pain with Julia. It makes deploying code require the entire environment, or a PackageCompiler built sys-image. I've played with static compiler, and other techniques. They are sadly quite brittle for my previous u

FWIW, I've used MaraDNS for a while, about 10 years. It works nicely for my small domains. It is missing some things that require I do some workarounds, but for the most part, it does what it says on the wrapper. Its not hard to con

So I pulled up my jpg of the Sombrero galaxy to see (its been my laptop background for a few years). I could barely make out Iris in it. Absolutely awesome though! Something about the deep field and ultra deep field pictures that makes me

Catastrophic loss of precision is, as the name implies, catastrophic in terms of the calculation context. For scientific/engineering codes, and things requiring a preservation of resolution for proper functioning, FP32 is rarely suffi

I don't support this at all. This is printing as a service, with interesting consequences once you cancel the service even with remaining assets available to you. To get you to think about this some more, apply this to computing and s

Back in my more perl-ish days, I recall pythonistas doing this. Sad to see little has changed.

I've been looking into that for a while, as a way to create a common environment for users in my team. I did get it to work, though as you mention, build times are long for this.

It is possible, within specific limits, using StaticTools.jl and StaticCompiler.jl. Sadly for me, my code won't work within the indicated limits. This is the biggest issue for me, for deployable code. I'd love to hand my users a

My packages at work are about 1.5k lines. Precompilation is about 10-15 seconds. After precomp, about 1-2 seconds to load with "import" or "using". The longest I've seen on precomp have been DifferentialEquations.

Fortran was old in the early 1980s, when I first taught it to myself for use on a research project. I'd taught myself BASIC, x86 assembler, and APL (for another physics course) by then. All the serious physicists were using Fortran t
