Samsung Galaxy XCover Pro 4G. From 2022 but there are newer models. So stop saying HUR HUR WATER RESISTANCE when people ask for phones with swappable batteries. This shows it can be done.

Edit: was $120, now sold out.

Many voters are willing to accept misinformation from political leaders – even when they know it’s factually inaccurate. According to our research, voters often recognize when their parties’ claims are not based on objective evidence. Yet they still respond positively, if they believe these inaccurate statements evoke a deeper, more important “truth.”

Is it ok? Is there something else you recommend instead? I tried nextcloud talk and it was pretty bad. Jitsi was ok but self hosting it looked complicated. FOSS only, of course.

Blog post by crypto professor Matthew Green, discussing what Telegram does (I wasn't familiar with it) and criticizing its cryptography. He says Telegram by default is not end-to-end encrypted. It does have an end-to-end "secret chat" feature, but it's a nuisance to activate and only works for two-person chats (not groups) where both people are online when the chat starts.

It still isn't clear to me why Telegram's founder was arrested. Green expresses some concern over that but doesn't give any details that weren't in the headlines.

This is a good blog post, with die photos of the new RP2350 chip and a brief description of what they show. There is a link to a 12 minute youtube video that is also very good, that discusses the die shots in more detail and also goes over the rest of the Pico 2 circuit board, including die shots of the QSPI flash chip and the voltage regulator chip.

This is a technical but quite informative article, nominally about which elliptic curves have good security properties, but also discusses the intentions behind using EC instead of older systems like RSA (basically, EC is safer against some known classes of attacks).

Posting partly because EC vs RSA came up here a few days ago.

The National Institute of Standards and Technology has finally published the world’s first three official post-quantum cryptographic algorithms, tools designed to protect key systems against future quantum computers powerful enough to crack any code generated by a modern computer.

Basically more everything. 2x Cortex M33 cores with floating point, 520KB ram, more PIOs, bunch of secure boot stuff (I have mixed feelings about this), and can boot to a mode with risc-v cores instead of the M33s.
