Madrid ↔️ Lisbon in just 3 hours – we're on board 🚄
Today, we adopted a plan to complete the Madrid–Lisbon high-speed rail connection by 2034.
This is a key step in fully integrating Portugal and Spain into the European high-speed rail network.

Out-and-out superb explanation.
📣THREAD: It’s surprising to me that so many people were surprised to learn that Signal runs partly on AWS (something we can do because we use encryption to make sure no one but you–not AWS, not Signal, not anyone–can access your comms).
It’s also concerning. 1/

PSA: we're aware that Signal is down for some people. This appears to be related to a major AWS outage. Stand by.

Wanted to look at the new line of Polk Audio speakers. Got about 5 pages into the site and got a Cloudflare block. I'm not using a VPN or anything else wonky. No more research into Polk for me.

Filling classrooms with computers didn't have the huge and positive impact on learning that was promised. Filling them with tablets hasn't done it either.
I know this might sound absurd to many (especially politicians) but what if we filled them with highly skilled and properly supported educators?
