**i have updated this post with the developer’s correct name** Hey just found out about this cool app called Emergency Chat! It’s on App Store and google play, and is made specifically for when you’ve gone into a nonverbal anxiety attack. It was made by Seph “Persephone” De Busser, an autistic computer science student. You just open it, hand someone your phone, it shows this cool message and then you can communicate via the chat. It’s like texting kinda but you’re both on the same phone. Super handy, right? You can even customize the alert message. Download it if you think it’d be helpful 😊
Alan Turing is the face of the new £50 note
The Bank of England has announced, following a public poll, that the new £50 note will feature mathematician, cryptographer and computer science pioneer Alan Turing. While this might seem like unambiguous good news, the issues it raises are more complicated than they first appear. Here’s a guest post from LGBT+ mathematician Calvin Smith with his… https://aperiodical.com/2019/07/alan-turing-is-the-face-of-the-new-50-note/

Some company is advertising by handing out USBs that look like thumb drives, but actually act as keyboards and open the company's webpage on any OS, sometimes by using the windows run dialog. This has given the attack vector more publicity and hopefully will remind people not to plug in random USBs they find. https://v.redd.it/6aygvuaqdq431
Breaking news in the algorithmic/arithmetic world!
Integer multiplication in time O(n · log n). 
It means you can multiply two n-bits integer using roughly n log n operations. It's a *very* important problem because a lot of mathematical software rely on efficient integer multiplication.
It breaks the last best known algorithm  (Schönhage–Strassen), that was in O(n · log n · log log n)
