🤯 "Hyper-Focal Pre-Optimization" 🤯
Coders from all over likely already know of this quote, or would certainly would benefit from perma-copying this quote to the front of their brain-stem/visual-cortex knowledge queue: > “Premature optimization is the root of all evil.” > ― Donald Ervin Knuth, The Art of Computer Programming, Volume 1: Fundamental Algorithms So then, what's this about Hyper-Focal in relation? It's when one builds a "maladapted neurological
FreeBSD Articles 2025 Q1 [projektierung]
These are the topics that I've been spending time with, on no specific schedule, with no intended intention, often for debugging or optimization, sometimes purely for curiosity, and often in-between other tasks throughout the day and night, so they might as well get some blog posts for discussion.

A Minor Commentary on SED/Opal Encryption
Data-At-Rest Encryption is a common topic, but one which is often misunderstood. Having led engineering and architectural efforts involved with hardware standards for encryption compliance, including detailed analysis of performance impacts while operating in accordance to service level agreements, here are some bits of discussion on the SED/Opal implementation. TL;DR * SED/Opal TCG spec'd drives are doing just fine. I trust it more than LUKS2 by
Performance & Regressions -- How Orgs Ship Code to Production
See that image? Right around the mid-section we see a common problem with the manner in which code is shipped to production. That one little section, displayed as a subsection of "build & packaging", happily named "regression + performance testing". Whether the product is a user-facing site, or middle-ware component, or baremetal systems which provide cloud resources that we all know and (sometimes) love... the success of
