92 units (1 MW or larger) were connected in the first half of 2026 adding 842 MW/1.8 GWh, which is more than all of 2025 so this is both happening and accelerating. In addition small scale storage also seems to be adding a significant amount of capacity.

The rail is laying on its side in that picture, so what is visible is the foot not the web.

Rust handles this by automatically unlocking when the MutexGuard returned by lock() is dropped. The issue here is not that the mutex remains locked, but rather that the data protected by the mutex might be inconsistent (and the mutex unlocked) after a panic.

And for the misuse angle there is this talk from Shmoocon 2011: https://www.youtube.com/watch?v=nLH7ytOTYto

One interesting thing about the dwarf format is that it is executable and Turing complete, running small programs on a virtual machine to figure out file names, line numbers and exception handling.

A local group of security people have been running a weekend project they call Project Lion Cage where they take Chinese cars into a local mine with spectrum analyzers etc. to watch where they send data and so on. This is how the bus was evaluated as well. Tor Indstøy has quite a few posts on his LinkedIn page talking about the work and what they have found.

That is a rebuttal of the International Association of Genocide Scholars[0] resolution from August[1], not this UN report.

The term of art you are probably looking for here is grid forming inverter. The ENTSO-E class list on Wikipedia is probably a good starting point for some of the problems that one might want to handle:

And to add to that, power is almost always the number that is reported/counted so watts is usually correct. That might seem strange since batteries store energy, but in terms of the service they provide to the grid power in/out is more important than storage at least for now.

Edit: 1-2 hours of storage seem to be the current state in Texas at the moment: https://www.renewableenergyworld.com/energy-storage/texas-co...

BloombergNEF reports a cost of $115 per kWh for turnkey energy storage systems (in China) so their comparison is likely to hold up for complete systems in Australia and the US.

The 6+2 spikes around the bright stars is a diffraction pattern created by the edges of the hexagonal mirror segments (the six large spikes) and the three struts that hold the secondary mirror (also six spikes, but four overlap with the mirror spikes).

This became RFC 8701 in 2020: https://datatracker.ietf.org/doc/html/rfc8701

The requirement is for the government to produce an impact statement (including carbon emissions in foreign countries and emissions from e.g. combustion) as part of the plan for development and operations that is presented to parliament for approval. This follows from the Supreme Court decision in 2020.

There is also a temporary injunction on further developments and decisions related to these three oil fields until the validity of the plan has been decided.

The District Court ruling was appealed by the government yesterday.
