Summary
The New York Times podcast with Ross Douthat discusses the concept of feminisation in society. They explore what it means, where it can be seen, and its benefits and derangements. The conversation also covers various topics such as growing up with another language, the impact of immigrant background, and the source of GOP derangement.

Fact

👥 Feminisation is now a common concept discussed by cultural gatekeepers such as The New York Times.

🤔 The conversation explores the concept of feminisation, what it means, where it can be seen, and its consequences.

💬 The conversation also covers various other topics such as growing up with another language and the source of GOP derangement.

💭 Diana Fleischman asserts that institutions are increasingly reflecting the values of middle-aged women.

Summary
Hash functions are functions that map a bit vector to another bit vector, usually shorter than the original vector. They have three primary uses: fast table lookup, message digests, and encryption. They exhibit the properties of uniform distribution and collision avoidance, and some hash functions also have the one-way property.

Facts

🔍 Fast table lookup is implemented using a hash function and a hash table.

🔐 Message digests allow for quick determination of whether two large bit vectors are equal.

🔒 Hash functions play an important role in encryption because they cause the encrypted data to be unreadable and unrecoverable without the decryption key.

📊 For a hash function to be useful, it must exhibit the property of uniform distribution.

🧩 Hash functions also exhibit the property of collision avoidance, meaning that unique inputs provide unique outputs.

🔙 Some hash functions have the one-way property, which is required for cryptography or fast table lookup with unknown keys.

Source: This infinite tiling pattern could end a 60-year mathematical quest

Summary
Mathematicians may have discovered the first single ‘aperiodic’ tile after searching for over 60 years. The tile can cover an infinite plane without making a repeating pattern, unlike periodic tilings. A modified version of the original tile was discovered and can build aperiodic tilings without being flipped.

Fact

🔎 Mathemeticians may have found the first single ‘aperiodic’ tile which can cover an infinite surface without repeating a pattern.

🧩 The tile is a breakthrough finding after 60 years of searching and differs from periodic tilings which have translational symmetry.

🔢 Roger Penrose’s work in the 1960s initially showed aperiodic tilings made of 20,426 tile types before finding tilings made of just two types that were not mirrored versions of each other.
