GitHub Pages are useful, but be careful to not set it up with a DNS Wildcard. It allows anyone on GitHub to host content on your subdomains, and it's actively being used, by paid GitHub accounts, to host scams
Bitcoin, less efficient than ever per block. Consuming a broader percentage of USA electricity every year.
> “we estimate electricity usage from Bitcoin mining based in the United States to range from 25 TWh to 91 TWh. That estimate represents 0.6% to 2.3% of all United States electricity demand in 2023”
💬🔒⚛️ Delighted to announce iMessage PQ3, our formally-verified protocol for end-to-end encryption that provides the strongest post-quantum protections against “Harvest Now, Decrypt Later” attackers by not only performing a quantum-secure key establishment, but also performing post-quantum ongoing rekeying.
De-orbiting satellites by burning them up did work when the volume of satellites was small, but already 10% of aerosol particules in the stratosphere contain aluminum/other metals. The problem is only going to get worse with the launch of megaconstellations https://www.pnas.org/doi/full/10.1073/pnas.2313374120
@jsq Hi Jesse! Before talking about Sealed Sender specifically, it's worth calling out that Signal does not send any push content other than a flag that says: “Connect to the Web Socket” and retrieve some messages”. The content is then fetched and decrypted in a Notification Service Extension and then displayed as a local notification to the user. https://github.com/signalapp/Signal-iOS/blob/b1027b670ea145073b12e5fb5c281a2facd3b61b/SignalNSE/NotificationService.swift#L105 APNS therefore never sees, even the Sealed Sender-encrypted ciphertexts, of the incoming messages.
The tide has started turning on the flow of tech workers.
> Europe is poaching more US talent than it loses to the country. 8,400 US tech workers have arrived in the region so far this year, compared to 8,300 heading across the Atlantic.
I wonder however how much is attributable to more US tech companies having European offices now.
I'm very excited about #Canopée's hard sails. The vessel will be transporting #Ariane6 to the Kourou launchpad.
The semi-rigid hard sails are expected to provide a 30%-50% fuel reduction depending on the wind direction. This has huge potential to reduce emissions of maritime transport.
Engine powered off, the ship sailed at 9.4 knots at a 50° wind bearing with a 19 knots wind, which is quite impressive.
It's a bit disappointing that @EC_Commissioner_Breton is promoting his move to BlueSky now on X, while forgetting that he has an account on the official instance of the European institutions.
European far right parties (Vlaams Belang, AfD, Rassemblement National, Lega ... ) are nominating Elon Musk for the Sakharov Prize for Freedom of Thought.
Gives you a sense of who wants to associate with this guy ...
