FreeCAD 3D Printing Notes

Avoiding Common Pitfalls Always ensure that 3D objects are solid PartDesign Workbench will notify you of any operations that would prevent the model from staying solid. Part Workbench has a Check Geometry tool, which can check for further defects Ensure your dimensions align properly Dimensions are vital: 1 millimeter in FreeCAD is 1 millimeter in real life Control degradation of the model, during transformation w/ the slicer (FreeCAD file -> a G-Code dialect) No printer will be able to directly create a 1:1 replica of the 3D object.

Grafana + Prometheus + Loki

Grafana Grafana open source software enables you to query, visualize, alert on, and explore your metrics, logs, and traces wherever they are stored. Grafana OSS provides you with tools to turn your time-series database (TSDB) data into insightful graphs and visualizations. Grafana proper does not provide any form of time-series database, nor does it provide any other data sources out of the box. Prometheus

Just-In-Time vs Just-In-Case

The difference between just-in-case and just-in-time is like the difference between training and trying. Person A never learned Algebra and never uses it. Person B learned Algebra in grade school and uses it daily. It would be hard to learn Algebra just in time. And the likelihood that Person B would use Algebra, if they had not learned it, is slim-to-nil What is the perfect balance of Just-In-Time learning vs Just-In-Case?

Mutual Funds vs ETFs

Mutual Funds are actively managed by a fund manager or a full team (though passively managed fund have a bit of popularity) ETFs are always passively managed Mutual Funds generally have a minimum investment amount (e.g. in the $500 - $5,000 min range) ETFs are bought and sold like stock and therefore are bought & sold similarly. They can even be shorted Mutual Funds will almost always have much higher expenses, especially due to them being actively managed.

Practical Electronics For Inventors

Definitions (A) ampere or amp (p6) Unit of current Interchangeable unit for 1 C/s (C) coulomb (p6) Unit of electrical charge Voltage potential difference or just potential (NOT potential energy) (V) volt (p14) Unit of measure of Voltage 1 volt = 1 joule / 1 coulomb Power (p14) power = dW/dt Chapter 2: Theory Voltage To get a mental image of how a battery generates an EMF through a circuit, we envision that chemical reactions inside yield free electrons that quickly build in number within the negative terminal region (anode material), causing an electron concentration.
