Agent memory needs its OpenTelemetry moment
Every agent tool stores memory in its own shape, and every week someone builds another one. None of them can read the others. Observability had the same problem until OpenTelemetry gave everyone one data model to share. A tour of today's memory formats, the proposals that already exist, and what a shared spec could…

Bidirectional charging during grid outages
David asked a great question on my solar battery system post: why buy a small battery just for emergencies when electric cars have a large battery you can also use for other things? [1] This would be great, and seems like the obvious way for it to work: when the grid goes down the panels can charge the car when it's…

Mystery of 60-Second Fluctuations in Power Grids Solved
Why do our grids show a brief spike in electricity demand every minute? A team led by Dirk Witthaut from Forschungszentrum Jülich has now demonstrated that this is due to regular power checks carried out by large-scale battery storage systems. These findings could help to make our electricity supply more robust, as…
