I saw a request a while ago asking for advice on some kind diagnostic logging (I can’t recall the details other than the person who asked). Worded another way the question is: how do apply a cross-cutting concern? When we: design our solutions around the ideas of queues, messages, events and streams & services (aka queries & commands) write code… Read more →
Cleaning pesky floor tiles
Step 1 Mop the floor with warm water and a cap full of distilled vinegar. Allow to dry. Step 2 Mix bicarbonate of soda (baking powder will not do) with water.
