Skin effect – Wikipedia

Posted by jpluimers on 2019/09/23

Skin effect – Wikipedia:

Skin effect is the tendency of an alternating electric current (AC) to become distributed within a conductorsuch that the current density is largest near the surface of the conductor, and decreases with greater depths in the conductor. …

At high frequencies the skin depth becomes much smaller. … Because the interior of a large conductor carries so little of the current, tubular conductors such as pipe can be used to save weight and cost.

28 Product Backlog and Refinement Anti-Patterns – Agile Transition

Posted by jpluimers on 2019/09/23

Food for thought: [WayBack] 28 Product Backlog and Refinement Anti-Patterns – Agile Transition

The most important one I learned: keep 20% slack and 20% technical debt+bugs (on a legacy system even more of the latter). This sounds like 40% waste, but is in effect a huge win as it makes the team much more flexible in responding to spikes, supporting team-mates (or cross functional teams) or having an off-day.
