Source: Bioacoustics: Finding the Voices of Other Species

Summary
Scientists are using “digital bioacoustics” to listen to the sounds made by plants and animals that are otherwise unperceived by humans. Small microphones are placed in different ecosystems to record a vast amount of data which is then run through an AI software that can identify the species in real-time and translate their sounds, creating an opportunity to better understand organisms and their needs.

Fact

🌱 Plants communicate their response to external and internal factors through distinct ultrasonic clicks or popping sounds, such as when stressed by dehydration or injured.

🐘 Scientists are decoding the sound frequencies of East African Elephants and Sperm Whales to create dictionaries of their communications.

🦜 Gabriel Jorgewich-Cohne successfully collected recordings from over 50 species of turtles previously understood to be non-vocal.

🐝 Tim Landgraf studies the social networks and collective intelligence of honeybee colonies to understand the link between their communication and behavior.

Source: Building vector search in 200 lines of Rust

Summary
Vector databases are commonly used for complex AI/ML applications and enable vector search. Vector search algorithms use pre-processing to identify points close enough to each other, making it possible to sub-linearly find nearest neighbors of any point. In this post, a simplified vector search index is built in Rust.

Facts

💡 Vector search enables sub-linear finding of nearest neighbors of any point in a space.

🧑‍🏫 Advances in AI in the early 2010s enabled the development of semantic representation of complex unstructured data using vectors in cartesian space.

🔍 Several state-of-the-art vector search algorithms exist, including HNSW and open-source efforts like Facebook’s FAISS.

💻 A simplified vector search index is built in Rust in this post, which uses pre-processing to identify points close to each other and allows for sub-linear finding of nearest neighbors of any point.

Source: Building a platform that open sources itself

Summary
Zed is building a platform for open-sourcing itself. Step one is to open up public channels, and step two is to build text-based conversations that link to persistent code annotations. Async contributions will be accepted when async workflows are supported.

Facts

💻 Zed’s remote team has been coding together on Zed for over a year.

🌍 Zed is building a platform for open-sourcing itself.

🗣️ Public channels will be opened for listening in, watching and chatting with the team, and even editing their code.

📝 Text-based conversations that link to persistent code annotations will be built to support async workflows.

👥 Contributions will be coordinated more efficiently by communicating earlier and in a more focused way.

Source: The Instant Pot Failed Because It Was a Good Product

that market is mostly served, there isn’t much room for growth. Even as the Instant Pot generated near-universal loyalty among its users, it also left itself open to competition from cheaper, faster, and more specialized gadgets. And as its parent company tried to launch other appliances under the Instant brand, it found that it couldn’t replicate the IP’s success—a sign that the Instant Pot didn’t so much revolutionize cooking as perfectly capture a specific set of needs that aren’t easily duplicated. Summary
The Instant Pot’s success was due to its ability to address a particular kitchen inefficiency and serve a specific market, but this proved to be a problem when the market became saturated and competition increased. The device’s popularity also overshadowed attempts to expand the Instant brand into other household gadgets.

Fact

🍲 The Instant Pot introduced plug-in pressure cooking, making it less intimidating than stovetop pressure cookers.

👨‍👩‍👧‍👦 The IP captured a specific set of needs for home cooks who regularly cook for multiple people.

💥 The Instant Pot’s success left it open to competition from cheaper, faster, and more specialized gadgets.

🧘‍♀️ The IP didn’t so much revolutionize cooking as it perfectly captured a kitchen inefficiency.

🏭 Instant Brands’ attempts to expand the Instant brand into other household gadgets were unsuccessful, highlighting the unique success of the Instant Pot.
