Summary
The article explains why the authors choose Lisp for their development language, citing its future-proof approach, longevity, and advantages in interactivity.

Fact

📈 Lisp’s future-proof approach allows for unlimited functionality through dynamically generated code and macros.

🕰️ Lisp code written 30 years ago can still work on a modern implementation, making it a language with longevity.

💻 Lisp’s interactive programming, aided by the use of the REPL and being image-based, allows for efficient and fluid development of ideas.

Source: AI voice scams: Report shares 77% of victims lose money, how common it is, and how to protect yourself

Summary
AI voice scams have become increasingly common and very convincing with up to 95% accuracy achieved via voice-cloning tools that are easy for attackers to obtain. According to McAfee, 25% of people surveyed around the world have either experienced an AI scam or known someone who has, and impostor scams as a whole are thought to have stolen $2.6bn in 2022. Victims of AI voice scams have lost between $1,000 and $15,000, so it’s imperative to limit what personal information you post online and ask challenge questions before parting with money.

Fact

📞👥 AI voice-cloning technology is slick and cheap, making it simple for criminals to duplicate samples from social media and trick people into believing loved ones are in need of emergency funds or are being held ransom.

🌎😞 According to McAfee’s report, 25% of respondents globally either experienced an AI scam or knew someone that had, with the highest-scoring country being India at 47%.

🎙️🕵️‍♂️ Impostors’ accuracy levels delivered by voice-cloning tools are almost indistinguishable from the real thing – 95%, according to McAfee’s research and reported victims. McAfee suggests regularly updating your social media privacy settings and keeping your voice off the internet to minimise exposure.

💸🆘 Sadly, 77% of victims of AI voice scams reportedly lose money, with 11% of them in the US losing between $5,000-$15,000.

Summary
SECD is a virtual machine for functional programming languages created by Peter Landin that targets the Stack, Environment, Code, and Dump registers and has a small and simple instruction set.

Fact

💻 SECD is a virtual machine targeting functional languages.

🤖 The SECD machine has four registers – Stack, Environment, Code, and Dump.

📝 Registers can be thought of as linked lists in memory that can change their contents during SECD machine execution.

📚 The instruction set of SECD machine is small and simple.

🔗 The dump register persists copies of the registers, allowing jumps without losing the place in execution.

🧪 SECD instructions are defined axiomatically, which allows implementors to have total control over the way instructions work under the hood.
