Your LLM Telemetry Table Does Not Have One Denominator

23+ min ago   (960+ words) Originally published on hexisteme notes. I had an LLM telemetry report with the usual reassuring furniture: medians, interquartile ranges, sample sizes, and bootstrap intervals. The rows were grouped by model. It looked ready for comparison. It was actually several different…...

# Beyond Transformers: A Mathematical Critique of Cross-Lingual Diffusion Architectures

23+ min ago   (424+ words) The current state of multilingual NLP is dominated by transformer-based architectures that often treat cross-lingual alignment as a secondary optimization task. For researchers and engineers working with low-resource languages or requiring strict semantic preservation, the "black box" nature of proprietary…...

Unreal C++ Course Chapter 109

23+ min ago   (220+ words) In this chapter we set up the enumerations for the player character's equip state, in my case AEchoCharacter. I declared my enumerations in a separate header file CharacterState.h which can also be used for other states besides equipping items:…...

k3s statt Kubernetes: Warum die Rancher-Distribution unschlagbar ist

20+ min ago   (691+ words) Hier kommt k3s ins Spiel. Entwickelt von SUSE (bzw. Rancher), ist k3s keine abgespeckte Spielzeugversion, sondern eine hochkompakte, aber voll CVE-konforme Kubernetes-Distribution. Sie wurde speziell für IoT, Edge Computing und CI/CD-Pipelines konzipiert, hat sich aber längst auch als extrem robustes Fundament…...

I Built a 100% Free AI Toolbox with No Sign-Up (Here's How)

22+ min ago   (202+ words) So I spent a few evenings building MagicKit — three tools in one page: The entire backend sits at around 60 MB RAM, because my server only has 1.6 GB to work with. The free image API only allows one queued request per…...

The AI Interview Paradox: Decoupling Skill Assessment from Tool Usage

20+ min ago   (617+ words) We must refactor the interview process. The goal is not to stop using AI, but to shift the focus of the evaluation from implementation details to systemic architecture and verification logic. In the AI era, the highest-leverage skill for a…...

We timed HTTP-only scraping against a headless browser on the same page. It wasn't close.

20+ min ago   (266+ words) Every one of our Actors is HTTP-only — no Puppeteer, no Playwright, no headless Chromium in production. We say this is faster and cheaper. This post is the measurement, not the assertion. Same target, two approaches, same box (1 vCPU / 2 GB RAM,…...
