Same for whatever implementation of the Budapest Convention on Cybercrime you are living under in your jurisdiction. Also for webcrawlers that ignore robots.txt. They are committing a criminal offence.
I really do not get why nobody is running to their public prosecutors to have a go at this.

I showed this to a central banker and their response was that this was less-than-terrific analysis given that the US money supply has grown fourfold between 2000 and 2025, so 82 USD now is not really comparable with 82 USD in 2000. If you adjust for inflation, 82 USD in 2025 was worth 43 USD in 2000. So the market's belief in Cisco in 2000 still has not been justified in 2025, at best we're halfway that valuation.

I know it is a bit of a downer on a #solarpunk future, the reality of China decarbonising this rapidly probably has more to do with a goal to be able to weather a disruption of maritime trade after an invasion of Taiwan than with mirigating the unfolding climate catastrophe.

If there is a general approach coming out of the Council of Ministers, there is little to nothing the MEPs can do to influence the trilogue and the second reading rarely leads to rejections. For now it is better to keep this dossier stalled in the Council of Ministers, so the national parliaments are where people should make noise at.

The permreps are useful, but even more useful would be to mention the national parliamentary committees that take this on. Tooting about MEPs is counterproductive at this stage.

Yes, that concept is questionable to begin with, but there are examples of stocks that had a P/E ratio of 30 at some point in their life and are considered "respectable" in ways that OpenAI is not. And the irrationality of financial markets does not need further pointing out.

2025-07-10 08:11:43 GMT

- reply

The article mentions a P/E ratio of 30 as excessive. While that is a high ratio, it is still within the bandwidth of "normal". For comparison, Tesla's P/E ratio is 160 which is frankly beyond ridiculous and in itself a sign that the stock market is in a bubble.

Eurostar is mailing me a checklist for a train trip to Brussels. Which is less than 120km, as the crow flies. Do the train operators realize that having to have seat reservations, being present at the (windy and cold) station 20 mins in advance etc is making trains as shit as flying and way worse than a car instead of making it a better proposition? Or do they just not care?

It helps for grid congestion. There are multiple challenges in the energy transition. The seasonal issue is separate from the daily fluctuations, the latter will be very much diminished once four to eight hour battery backup becomes normal. The seasonal issue will have regional solutions and requires a regional energy mix that fits the regional seasonal changes.

Hard disagree, some of the best presentations I have witnessed had their slide decks thrown together in the back of a taxi on the way from the airport to the conference venue. Conversely, some of the worst had been rehearsed over and over beforehand. A good presentation comes from the presenter being on top of their game, both on substance and on presentation skills. A true expert can talk for an hour on their topic when you wake them up in the middle of the night.
