@pickover @pickover , have you done Wordle today?

Signal has rolled out usernames, meaning users can now use the app while keeping their phone numbers private. This enhanced level of privacy was achieved through the use of Ristretto hashes and zero-knowledge proofs.

We wanted to take a deeper look into how these two cryptographic primitives can provide another privacy protection for Signal’s users; fortunately, the source code is open-source, so let’s dive in.

“ValiDrive”
New GRC Windows utility to quickly spot-check any USB mass storage drive for deliberate sizing fraud and errors:

Over the next day I'll be fleshing out its description page. But the Windows App is ready for the world now! 👍

National Lab (LBNL) results support LK-99 as a room-temperature ambient-pressure superconductor.

Simulations published 1 hour ago on arxiv support LK-99 as the holy grail of modern material science and applied physics.
(https://t.co/UOOtDlx3eE)

Here's the plain-english explanation:
- The simulations modeled what the original Korean authors proposed was happening to their material - where copper atoms were percolating into a crystal structure and replacing lead atoms, causing the crystal to strain slightly and contract by 0.5%. This unique structure was proposed to allow this amazing property.

- @sineatrix from Lawrence Berkeley National Lab simulated this using heavy-duty compute power from the Department of Energy, and looked to see what would happen to the 'electronic structure' of this material, meaning, what are the available conduction pathways in the material.

- It turns out that there are conduction pathways for electrons that are in just the right conditions and places that would enable them to 'superconduct'. More specifically, they were close to the 'Fermi Surface' which is like the sea-level of electrical energy, as in '0 ft above sea-level.' It's believed currently that the more conduction pathways close to the Fermi surface, the higher the temperature you can superconduct at (An analogy might be how its easier for planes to fly close to the surface of the ocean due to the 'ground effect' that gives them more lift.)

This plot in particular shows the 'bands', or electron pathways, crossing above and below the Fermi surface.

- Lastly, these interesting conduction pathways only form when the copper atom percolates into the less likely location in the crystal lattice, or the 'higher energy' binding site. This means the material would be difficult to synthesize since only a small fraction of crystal gets its copper in just the right location.

This is insanely bullish for humanity.

Dear @1BlockerApp, we don't mind that you're using AdGuard's filtering engine library in your macOS app. However, we would like to remind that if you're using a GPL-3 library, you must make your app open source as well.

Waiting for the link to your source code in reply.

@foretwenty @Tylersjourney_ @jordaninglee @Ledger Perhaps someone has physical access to the seed phrase, if you've stored it somewhere. Or to the ledger device (if they ascertained your PIN)?

@freekwiedijk Could it be that someone delivering something accidentally urinated while they were trying to get down to the low letterbox?

Just thinking about how the United States could have been the world leader in 5G technology instead of China if we had just given *one guy* a green card when he needed one

Ultimately, Trade Unions work and that is exactly why the Tories are going after them.

[Andrew @NigelBeans]

@UpholdInc Aha. I now have a reply from @UpholdInc to my support ticket. They reckon they've had no breach. I've sent some more information to them.

[Andrew @NigelBeans]

Still no reply from @UpholdInc to my support ticket, and no acknowledgement on Twitter. Today I received another #SCAM #phishing email to my email address which is used only for Uphold

[Andrew @NigelBeans]

@UpholdInc why am I receiving #phishing #scams to an email address (includes a random string) used only for Uphold? What are you doing about it? No response to my support ticket. Have your systems been breached? Are you to react responsibly? Warn customers? Acknowledge please

[Andrew @NigelBeans]

@goed_be @Lez020 @DiedSuddenly_ You're missing the point. @DiedSuddenly_ IS showing something. @Lez020 is commenting on what is being shown, and their reply to you is almost correct. Pointing towards some proper evidence could suffice.

@thomas_quinlan @UpholdInc @AskUphold @exodus_io I got a 2nd #phishing email today, sender domain https://t.co/MHUtpI2hYr . First was from https://t.co/iA3buaYcGa

Both a DKIM pass

@exodus_io @thomas_quinlan @UpholdInc @AskUphold I've received a second follow up email today. The theme was the same. I can send you the .eml files, but first I'd like to redact some stuff.
