Darwin’s complete Galapagos library posted online

Charles Darwin's massive ship library, including astounding drawings of species from far-off lands, meant he rarely had to come above-board while sailing on the Beagle in the 1830s.

Charles Darwin's five-year journey to and from the Galapagos Islands ended in 1836. While that was over two decades before the publication of On the Origin of Species, he credited his time on board the Beagle as a formative experience for his theory of evolution. That extended trip wasn't only spent studying local wildlife, especially during lengthy voyages at sea to and from home—Darwin also devoured a library of more than 400 volumes of text.

While many of those books were referenced in his later research, they were not preserved as a collection once the Beagle returned to England, leaving a gap in our understanding about the books and studies that kept Darwin's mind occupied during such an historic era. Now, thanks to the painstaking efforts of a two-year Beagle project funded by the government of Singapore, that complete on-ship library has been transcribed and posted at Darwin Online, the world's largest repository of Darwin-related texts and writings.

The library, which was stored in the same cabin as Darwin's bed and desk during his journey, totaled out at 195,000 pages by the time researchers at the National University of Singapore assembled the full collection (and these weren't exactly picture books, with only 5,000 corresponding illustrations). The complete list is quite astounding, made up of atlases, history books, geology studies, and even a giant supply of literature. Darwin also enjoyed a few books in French, Spanish, and German, along with a book in Latin about species and a Greek edition of the New Testament.

Bitcoin pool GHash.io commits to 40% hashrate limit after its 51% breach

Bitcoin pool GHash.io announced on Wednesday that "it is not aiming to overcome 39.99 [percent] of the overall Bitcoin hashrate."

This marks a clear departure from the large pool's recent flirtations with 51 percent. If that threshold is crossed for sustained periods of time, it concentrates power in ways that Bitcoin's decentralized design normally does not allow.

"If GHash.io approaches the respective border, it will be actively asking miners to take their hardware away from GHash.io and mine on other pools," the statement continues. "GHash.io will encourage other mining pools to write similar voluntary statements from their sides."
