Germany's public energy register lists 9.7 million installations with operator contacts

·4 views

Germany's Federal Network Agency maintains the Marktstammdatenregister, a public register that legally must record every energy installation in the country. The records cover solar parks, wind turbines, home batteries and biogas plants, each with GPS coordinates, capacity, commissioning dates and voltage level. Operating companies' business contact details are also included, and the data is published under Germany's open data license. The author describes a JSON endpoint behind the website that can be queried without authentication, and shows how filters can isolate utility-scale solar parks. The article also promotes a paid scraping tool built on this endpoint and notes that private individuals are anonymized while GDPR still applies to downstream use.

Benchmarking Node.js setTimeout at Scale: Memory, Lateness and Restart Risks

A DEV Community article argues that the question of how many setTimeout calls Node.js can handle depends on the specific machine, so it offers a benchmark script rather than quoting figures. The author deliberately withholds personal results, since they would not transfer to other servers, Node versions or workloads. The benchmark measures per-timer memory cost, lateness relative to scheduled times, and the effect of many pending timers on event-loop delay. It recommends running the script at several sizes, adding background CPU load and using realistic payloads for more representative results. The article also flags that pending timers are lost when a process restarts, a risk that cannot be measured by the script itself.

CloudSlasher Aims to Turn Cloud Cost Visibility into Actionable Optimization

The author, a developer who built their own technology products, found that cloud spending was hard to trace and wanted to make cost optimization more actionable. That experience led to the creation of CloudSlasher, a platform intended to go beyond cost dashboards. The piece argues that knowing a resource is expensive does not show teams whether it can be changed safely, since operational context such as production dependencies and performance needs matters. Because AWS, Azure, Oracle Cloud Infrastructure, Google Cloud, and Kubernetes each use different resource models, pricing, and APIs, building a multi-cloud tool poses engineering challenges. The article outlines these considerations, including resource discovery, utilization analysis, and preserving provider-specific context.

How to Calculate Topsoil Volume in Cubic Yards With a Simple Formula

A short guide explains that a topsoil calculator needs only one multiplication and one division, with most errors coming from measurement rather than arithmetic. Volume in cubic yards is found by multiplying length, width, and depth in feet, with depth in inches divided by 12, and then dividing by 27. Worked examples include a 4 by 8 foot raised bed at 6 inches deep, needing about 0.59 cubic yards, and a larger 10 by 12 foot bed at 4 inches, needing about 1.48 cubic yards. Round beds are handled by computing circular area from the diameter, and irregular shapes should be split into rectangles and summed. The author recommends averaging several depth readings and ordering about 10 percent extra soil to allow for settling.

How a Gauge-to-Millimetre Converter Works: Wire Formula and Lookup Tables

A gauge number is not a direct thickness, so a converter combines one formula with several lookup tables. For American Wire Gauge, diameter in millimetres equals 0.127 multiplied by 92 raised to the power of (36 minus AWG) divided by 39, which yields roughly 2.05 mm for 12 AWG. Sheet metal uses the agreed Manufacturers Standard Gauge table instead of a formula, and its millimetre values differ by metal, such as 16 gauge copper versus 16 gauge brass. Needle gauges are also fixed by an international standard, so they are best handled with a lookup table. The author notes that gauge numbers run inversely to thickness in all three systems, which can look like a bug to new users unless explained.
