Submission + - BitTorrent Performance Test: Sync Is Faster Than Google Drive, OneDrive, Dropbox 1

An anonymous reader writes: Now that its file synchronization tool has received a few updates, BitTorrent is going on the offensive against cloud-based storage services by showing off just how fast BitTorrent Sync can be. More specifically, the company conducted a test that shows Sync destroys Google Drive, Microsoft’s OneDrive, and Dropbox. The company transferred a 1.36 GB MP4 video clip between two Apple MacBook Pros using two Apple Thunderbolt to Gigabit Ethernet Adapters, the site as a real-time clock, and the Internet connection at its headquarters (1 Gbps up/down). The timer started when the file transfer was initiated and then stopped once the file was fully synced and downloaded onto the receiving machine. Sync performed 8x faster than Google Drive, 11x faster than OneDrive, and 16x faster than Dropbox.

The problem with Webtender (and the other, very similar, drinks-making sites I've seen) suffer from the problem that every combination of liquids, however repulsive, has been given a whimsical name and logged as a permissible "mixed drink". So if you tell it that your liquor cabinet holds a half-empty bottle of dry vermouth, a dusty bottle of Peychaud's bitters and a jar of cocktail onions; it's going to give you a list of nine different "drinks" you can make.


Tesla's New York Laboratory Up For Sale 183

Ziest points us to NY Times piece on the battle over the site of Nicola Tesla's last failed experiment. Tesla's laboratory, called Wardenclyffe, located on Long Island, has been put up for sale by its current owner, Agfa Corp. Local residents and Tesla followers were alarmed by a real estate agent's promise that the land, listed at $1.6 million, could "be delivered fully cleared and level." Preservationists want to create a Tesla museum and education center at Wardenclyffe, anchored by the laboratory designed by Tesla's friend, Stanford White, a celebrated architect. "In 1901, Nikola Tesla began work on a global system of giant towers meant to relay through the air not only news, stock reports and even pictures but also, unbeknown to investors such as J. Pierpont Morgan, free electricity for one and all. It was the inventor's biggest project, and his most audacious. The first tower rose on rural Long Island and, by 1903, stood more than 18 stories tall. ... But the system failed for want of money, and at least partly for scientific viability. Tesla never finished his prototype tower and was forced to abandon its adjoining laboratory."

Why Text Messages Are Limited To 160 Characters 504

The LA Times has a story about Friedhelm Hillebrand, one of the communications researchers behind efforts to standardize various cell phone technologies. In particular, he worked out the 160 character limit for text messages. "Hillebrand sat at his typewriter, tapping out random sentences and questions on a sheet of paper. As he went along, Hillebrand counted the number of letters, numbers, punctuation marks and spaces on the page. Each blurb ran on for a line or two and nearly always clocked in under 160 characters. That became Hillebrand's magic number ... Looking for a data pipeline that would fit these micro messages, Hillebrand came up with the idea to harness a secondary radio channel that already existed on mobile networks. This smaller data lane had been used only to alert a cellphone about reception strength and to supply it with bits of information regarding incoming calls. ... Initially, Hillebrand's team could fit only 128 characters into that space, but that didn't seem like nearly enough. With a little tweaking and a decision to cut down the set of possible letters, numbers and symbols that the system could represent, they squeezed out room for another 32 characters.
