With my new Sovol SV06 “ACE”, I learned the hard way what the Y-belt tension dial does 😄
Too loose → ~20 mm layer shift mid-print.
I used Gates Carbon Drive to tune belt “twang” frequency, then built a stress test suite to validate motion stability:

`Understanding Model Calibration -- A gentle introduction and visual exploration of calibration and the expected calibration error (ECE)`
To be considered reliable, a model must be calibrated so that its confidence in each decision closely reflects its true outcome. In this blogpost we'll take a look at the most commonly used definition for calibration and then dive into a frequently used evaluation measure for model calibration. We'll then cover some of the drawbacks of this measure and how these surfaced the need for additional notions of calibration, which require their own new evaluation measures. This post is not intended to be an in-depth dissection of all works on calibration, nor does it focus on how to calibrate models. Instead, it is meant to provide a gentle introduction to the different notions and their evaluation measures as well as to re-highlight some issues with a measure that is still widely used to evaluate calibration.
`This study presents a novel calibration assessment framework for ML models, designed to address the limitations of existing popular metrics, particularly the ECE. Our framework enables a more fine- grained evaluation of calibration by assessing model performance locally, for different confidence regions or classes, providing a com- prehensive understanding of the model’s behavior.`

Типовая разметка памяти STM32
Как вы могли заметить у микроконтроллеров STM32 секторы NOR Flash памяти облазают разным размером: 16kByte(4 шт), 64kByte (1 шт), 128kByte ( 7+ шт.). Это накладывает определенную специфику на программирование микроконтроллеров STM32. Из каких секций обычно состоит Flash память микроконтроллерной программы? В этом тексте я предлагаю решение проблемы разметки памяти для случая работы с микроконтроллерами STM32.

C. M. Lowery et al. (2026) discovered a quick #recovery of #marinelife after the #massextinction ~ 66 Ma ago. They calculated a new #calibration using the #biostratigraphic #marker (#Helium-3 from 6 K/Pg boundary sites) and dated the #duration until the recovery of the #foraminiferbiozone of 3.5 k.y. - 11.1 k.y. after the boundary, instead of former theses ∼30 k.y..

Made new test prints on some off-cuts, using a slightly stronger developer solution than usual to see impact on max. depth. The main image (Eagle Creek, Oregon) is using 18% sodium acetate (curve corrected negative), the test strips are of 20% and 15% solutions (both uncorrected). The phone capture doesn't really show the differences too well, but I think I will go for the 18-20% from now on...
