When David Smith, Joseph Myers (@jsm28), Chaim Goodman-Strauss and I posted our paper "An aperiodic monotile" ( back in March, we answered the open problem of whether a single shape could tile the plane aperiodically.

Some people observed that tilings by the "hat" used both unreflected and reflected tiles. Although the einstein problem was answered, in some contexts (e.g., tile floors), you'd likely have to manufacture two separate tiles. Our paper left open the question of whether a shape could tile aperiodically using translations and rotations only, with no reflections.

I hate to sound like a broken record, but then, on March 26th, Dave noticed something interesting. (1/n)

Does that matter? Hang on, there's one more step! Because Tile(1,1) is equilateral, and because we're not using reflections, it's easy to modify its edges to *force* it to tile without reflections.

These shapes, which we call "Spectres", are "strict chiral aperiodic monotiles": shapes that are forced to tile aperiodically, and can't use reflections! If you objected to the hat because of its reflections, this is the shape for you. (6/n)

Alberta, vote today! How is it that the UCP is polling ahead of the NDP? I know that Alberta likes their conservative governments, but with the things that Smith has said and done, the UCP shouldn't be polling so high. Get out and vote. It doesn't matter if you're in a "safe Blue", or a "safe Orange" riding. Vote!
I have to laugh and shake my head at Smith calling it a "Miracle on the Praries". No, you were leading in the polls pretty much the whole time. You're in a strongly conservative province. I mean, if you're saying that it's a miracle that the majority of Albertans chose to ignore your terribleness, then yes, sure. But people voting the same way the polls said they would isn't a miracle. If the UCP ran with a saner leader, they probably would have won by a lot more.

Gajim 1.8.0 has been released 🥳 and it comes with integrated OMEMO encryption! Integrating the OMEMO plugin brings tighter integration and better user experience.

We also rearranged the chat menu and added some quick buttons for convenience.

Both Gajim’s message search and conversation view received some important changes and fixes.

Thank you for all your contributions!

“People who criticize new technologies are sometimes called Luddites, but it’s helpful to clarify what the Luddites actually wanted. The main thing they were protesting was the fact that their wages were falling at the same time that factory owners’ profits were increasing, along with food prices. They were also protesting unsafe working conditions, the use of child labor, and the sale of shoddy goods that discredited the entire textile industry. The Luddites did not indiscriminately destroy machines; if a machine’s owner paid his workers well, they left it alone. The Luddites were not anti-technology; what they wanted was economic justice. They destroyed machinery as a way to get factory owners’ attention. The fact that the word #Luddite is now used as an insult, a way of calling someone irrational and ignorant, is a result of a smear campaign by the forces of capital.”

So, many parts of Alberta are on fire and have been most of the last week. It is getting really bad today. So of course, the conspiracy theories are flying as hot and thick as the smoke. "the environmentalists are doing it", "the government is infiltrated by... WEF", "it's chemtrails", "it's climate fire bugs", "it's Trudeau's fault" (of course) and "they are trying to burn everyone out so they have to move to "smart cities". JFC.

But not one person talking about fossil fuel driven climate change and it's contribution to extreme drought and heat. No one is suggesting maybe we should give every support we can to those that are developing non-fossil fuel energy systems. No one is saying we should all use less energy, buy less crap, live more simply. My heart is broken by the photos coming out of Alberta today. Innocents suffer for the greed and bullshit of the few.

"Federated, peer-to-peer, encrypted, Free Software apps/software like #Element and #Briar, should be promoted. They are key to our national security as they provide means to enable sovereign, private and secure communication to citizens of India. Element has been embraced by Governments of France, Germany and Sweden which should be an example for #India."

Govts themselves are funding and arming terrorists in other countries. If this has to work, all countries will have to come together, which is unlikely.
Pirate Praveen mastodon (AP)
@internetfreedom almost all mainstream media has ended up being just PR agency of the govt - they did not even ask about transparency or contact the banned apps. We need to inform media and general public about the impact of the ban on our fundamental right to #privacy.

What a terrible thing to hear about. As an Element user myself, this is absolutely disheartening.
It's really stupid thing saying that Element or Briar doesn't have representatives in India. That's not too different from asking that Linux should have representatives in India.
Pirate Praveen mastodon (AP)
@Breakfastisready@internetfreedom that is even a violation of the IT act which they have used as an excuse here. Only significant intermediaries that has 50 lakh users need to have a representative in India.

This is a dangerous precedent and opens the door to ban any app/service not having a presence in India. We should challenge this order in the Supreme Court.

Ugh. Why did they move the "Start" menu away from the corner? And there seems to be no way to move it back.

It's taking over 4 hours to download a VM image of Windows with Visual Studio that will expire and be unusable in 3 months (and I'm lucky that such a VM is even available, though I won't be surprised if, after it's done downloading and I've set it up, I find out it isn't what I need). It took about half an hour to download a VM image of FreeBSD that will never expire. I hate working with proprietary software.

Google has just updated its 2FA Authenticator app and added a much-needed feature: the ability to sync secrets across devices.

TL;DR: Don't turn it on.

The new update allows users to sign in with their Google Account and sync 2FA secrets across their iOS and Android devices.

We analyzed the network traffic when the app syncs the secrets, and it turns out the traffic is not end-to-end encrypted. As shown in the screenshots, this means that Google can see the secrets, likely even while they’re stored on their servers. There is no option to add a passphrase to protect the secrets, to make them accessible only by the user.

Why is this bad?

Every 2FA QR code contains a secret, or a seed, that’s used to generate the one-time codes. If someone else knows the secret, they can generate the same one-time codes and defeat 2FA protections. So, if there’s ever a data breach or if someone obtains access .... 🧵

End-to-End encryption is one of the good things we have with the current internet and app ecosystems. But it is under constant threat -- be it from EU's #chatcontrol, UK's "online safety bill" or the current renewed "EARN IT" effort in the US: ....
anyone of these efforts succeeding would be a dangerous dam break. Let's collectively make sure all these governmental anti-privacy efforts fail!

Along similar lines is how everyone used to "know" that you couldn't fold a piece of paper in half more than 8 times, until a high school student figured out the requirements for folding n times, and then proceeded to fold a (very, very long and thin) piece of paper 12 times.
