Edit: Wow I didn't know that SumatraPDF Reader is also FOSS. Awesome!

I'm also a fan of your sandboxing post. Got to know of nsjail and gVisor. Looking forward to your Macaroons post, don't care when it arrives.

"The Facebook-owned smartphone app said in a blog post that once a message has been forwarded from one user to another more than five times, anyone getting the message will be able to send it along to only one other person or chat group."

They can't read message contents.

Here are some cases of mass 'hacking' of Telegram. The problem with Telegram is these 'hacks' give attackers access to entire Telegram chat histories, unlike E2E apps like Signal, WhatsApp, Wire etc.

Hack is in quotes because all involve SMS interception.

The defense against that is 'disappearing messages' which is available in most popular E2E messaging apps nowadays, including Signal and WhatsApp.[1]

PGP emails doesn't even have forward secrecy. Emails are not messaging, it needs video/voice calls, stickers/gifs etc etc to have any hope of being adopted by non-techy folks.

The Signal blog has a number of articles on how they develop state-of-the-art privacy preserving features. [2][3][4][5][6].

Also the only info Signal has about you is "Unix timestamps for when each account was created and the date that each account last connected to the Signal service", which is what it provides to government requests [7].

There's also two early-twenties women who flew Atlantic and Pacific 3 yrs ago - Aarohi Pandit and Keithair Misquitta. I think plans changed and Aarohi completed most of the journey solo [1][2][3]. There are also cockpit videos of women pilots from across the globe on YouTube [4].

Isn't a Pipistrel Sinus 912 smaller than Cessna 210? Two young Indian women crossed the Atlantic and Pacific on it 3 yrs ago. Aarohi Pandit and Keithair Misquitta. I think plans changed and Aarohi completed most of the journey solo. I checked for long video of their flight but couldn't find any, if anyone has it please link.
