This is a comprehensive description of the cryptographic hash function BLAKE, one of the five final contenders in the NIST SHA3 competition, and of BLAKE2, an improved version popular among developers. It describes how BLAKE was designed and why BLAKE2 was developed, and it offers guidelines on implementing and using BLAKE, with a focus on software implementation.

In the first two chapters, the authors offer a short introduction to cryptographic hashing, the SHA3 competition and BLAKE. They review applications of cryptographic hashing, they describe some basic notions such as...

Does culture matter? This question has taken on added significance since fundamentalist revivalism has recently gained ground in different parts of the world. The old controversy between Max Weber and Karl Marx, which centres around the extent to which cultural factors such as social norms and values affect economic growth is of critical importance, particularly because of its policy implications. Indeed, if culture is not an autonomous factor susceptible to influencing economic realities, it should not matter and public authorities can dispense with thinking about cultural interventions....

* First of three independent, self-contained volumes under the general title, "Lie Theory," featuring original results and survey work from renowned mathematicians.

* Contains J. C. Jantzen's "Nilpotent Orbits in Representation Theory," and K.-H. Neeb's "Infinite Dimensional Groups and their Representations."

* Comprehensive treatments of the relevant geometry of orbits in Lie algebras, or their duals, and the correspondence to representations.

* Should benefit graduate students and researchers in mathematics and mathematical physics.

The current cultural climate in France is often described as one of "declinisme" or "sinistrose," a mixture of pessimism about the national future, nostalgia for the past, and a sinister sense of irreversible decline concerning the present. The notion of "democratic melancholia" has become widely popular, cropping up time and again in academic papers and newspaper articles. In Melancholy Politics, Jean-Philippe Mathy examines the development of this disenchanted mood in the works of prominent French philosophers, historians, and sociologists since the beginning of the 1980s.
