Finally got to use MCE::* in a project

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 […]

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 […]

Raw Unapologetic Firepower: kdb+ from @Kx

While the day job builds (hyperconverged) appliances for big data analytics and storage, our partners build the tools that enable users to work easily with astounding quantities of data, and do so very rapidly, and without a great deal of code. I’ve always been amazed at the raw power in this tool. Think of a […]

“Unexpected” cloud storage retrieval charges, or “RTFM”

An article appeared on HN this morning. In it, the author noted that all was not well with the universe, as their backup, using Amazon’s Glacier product, wound up being quite expensive for a small backup/restore. The OP discovered some of the issues with Glacier when they began the restore (not commenting on performance, merely […]

There are no silver bullets, 2015 edition

In Feb 2013, I opined (with some measure of disgust) that people were looking at various software packages as silver bullets, these magical bits of a stack which could suddenly transform massive steaming piles of bits (big … uh … “data” ?) into golden nuggets of actionable data. Many of the “solutions” marketed these days […]

Updated net-tools bits

So far, 3 components, and working to fix a few things in formatting. On github, grab it here.

Real measurement is hard

I had hinted at this last week, so I figure I better finish working on this and get it posted already. The previous bit with language choice wakeup was about the cost of Foreign Function Interfaces, and how well they were implemented. For many years I had honestly not looked as closely at Python as […]
