Slack have decided to start training AI on enterprise customer data, including DMs, private workspaces and files. You have to have admin opt out via email. HT @Quinnypig
@GossiTheDog@Quinnypig@kentindell this is actually a major issue. How do they guarantee that, by this way, corporate IP won't leak? How can I trust that there will not be information (even just sentiment) that can be attributed to specific users?
Falsche Stadtplanung: #Berlin fürchtet sich vor Hitzewellen und Überflutungen nach #Starkregen. Aber lange Zeit wurde ohne jedes ökologische Gespür gebaut - wie zum Beispiel der Walter-Benjamin-Platz. Leitbild: „steinernes Berlin“. Schon damals gab es Alternativvorschläge mit Kleingewässern und Bäumen - sie wurden weggewischt.
With #renewables, even just domestic solar panels and privately installed batteries we can get domestic electricity mostly for free in a few years in many developed regions of the world. The electricity companies will do everything to make that impossible. But their claims of a grid that can't cope only shows their centralised approach that favours big consumers is failing ;)
@jwildeboer the biggest challenge is, as far as I know, load control of decentralized networks. AC networks regulate generation to meet consumption by frequency and I have heard people explain that the very fast reaction of local inverters can be an issue as the grid is built around the idea of rotational mass as a primary capacity reserve. So more consumption, some turbine spins slower, frequency drops, somewhere more power is added to the grid. AFAIK, inverters have simulated rotational mass.
@jwildeboer hmm... I would not paint it a malicious thing, it is a simple (and rather ingenious) way to control the grid without having to build additional communication devices.
But of course it's by no means an unsolvable problem. We would only have to replace the medium to low voltage transformers with a double set of rectifiers / inverters (for bidirectionality) and a high voltage DC coupling. We have the technology. But for this to work, we will also need a global (well, grid global)
@jwildeboer hmmm, Alternatively, those couplers could behave like rotational masses towards their two AC ends. That would make an interesting experiment
@jwildeboer technically, that's pretty much what every rooftop solar system is today, but larger. My system has a 900V DC level and can feed 400V three phase AC into the grid.
