ISPs warm to IPv6, but old-era Internet plumbing persists

Internet service providers are gradually warming to IPv6, the technology for a vastly more capacious Internet, but there are also signs of a technique to extend the useful lifespan of IPv4.

IPv4 has served the Net well, but it doesn't have enough addresses for all the world's devices. IPv6 opens the doors for uncountable numbers of devices, but the transition to support it has dragged on for years. A survey by the Number Resource Organization (NRO), a group that represents several central powers that allocate Internet address, shows that ISPs are slowly getting IPv6 religion.

Of 646 ISPs … Read more

Google gooses Chrome with network speed-boost idea: 'QUIC'

On the heels of its SPDY success for goosing Web communications standards, Google is tinkering with an even lower-level protocol with a project called QUIC.

To see if the technology meets its potential without causing new problems, Google has built QUIC into developer versions of Chrome and enabled it for a fraction of users. The hope is that it will cut the round-trip time of the back-and-forth communications between computers on the Internet, according to a blog item posted Thursday by Google engineer Jim Roskind.

"If we're able to identify clear performance wins, our hope is to collaborate … Read more

Transfer files and more with Cyberduck, but at a price

With a name like Cyberduck you might be wondering what type of app this is. Most people will not guess that Cyberduck is an open-source FTP browser designed for file transfers. At $23.99, Cyberduck has to provide a lot of capabilities to compete with free FTP systems.

As an FTP download and upload client, Cyberduck works well. The interface is clean and easy to work with. You can browse through folders and preview files in a Quick Look window, and you can also launch editors from within the Cyberduck tool to make changes to files. Unlike most FTP tools, … Read more

Researchers, Lego robot test Internet protocol for space

NASA and the European Space Agency say they have successfully tested an interplanetary communications protocol, with astronauts on the International Space Station using it to control a Lego robot in Germany.

The protocol is called Disruption Tolerant Networking (DTN), and one of its creators is Vint Cerf, who helped come up with the original Internet Protocol suite. NASA and the ESA said on Thursday that DTN may one day allow "internet-like communications" with spaceships and help support infrastructure on other planets.

"The demonstration showed the feasibility of using a new communications infrastructure to send commands to a … Read more

Rabbis call on Apple to ban anti-Semitic iTunes book

Apple is again facing controversy over an item being sold through iTunes.

The Conference of European Rabbis wants Apple to remove a book known as "The Protocols of the Elders of Zion," which is being sold as a 99-cent e-book through iTunes.

The Protocols, which surfaced early in the 20th century, purports to reveal a Jewish conspiracy to take over the world. The book has since been discredited as a fake but was used by Nazis and is still used by some hate groups to justify their anti-Semitism.

The rabbis are concerned that the book's availability in … Read more

Transmit even faster

Transmit was already one of the very best FTP clients for the Mac, and it's only gotten better with its long-awaited leap to version 4.

The two most noticeable things about the new Transmit are faster speeds (especially when dealing with lots of smaller files) and a completely revamped, more Finder-like interface. Transmit's snappy, animated new interface makes workflows more natural and streamlined than ever. The file browsing has also gotten easier, with new features like "Places" (for storing shortcuts to frequently used folders) and useful Finder-style functionality (which has been showing up in other FTP … Read more

New this week on Blu-ray: 'Mission: Impossible - Ghost Protocol'

You can call it "Mission: Impossible 4" or Tom Cruise's comeback flick after a career that suddenly hit the skids. But whatever it's called, Paramount's done another stellar job with the video transfer and the Blu-ray version offers impressive fine detail along with an equally dynamic soundtrack to back up the picture quality.

As for the movie, well, it's also pretty good, so this one might very well be worth a purchase rather than a rental.

I know, I know, a lot of you don't buy discs anymore, you just stream everything or … Read more

Fetch those files

Fetch is one of the oldest and most well-loved FTP clients, whose cute fetching-dog animation has been running--literally--on Macs since 1989. Fetch can handle all your basic FTP needs, including SFTP and FTP with TLS/SSL, along with support for AppleScript and one-click remote file editing (with any kind of file and any kind of application). In addition to a fairly minimal and intuitive visual interface, Fetch saves you time with extras like Quick Look previews (optimized for OS X), easy drag and drop (including droplet shortcuts that save you from having to retype connection information), progress-tracking Dashboard widgets (shaped … Read more

How to show the full URL in Firefox

Firefox made a change to how URLs are displayed when visiting Web pages. Unfortunately, if you're trying to find out if you're on a secure connection by reading the protocol at the start of the URL, you can't do that anymore. Here's a quick fix for getting the protocol back in the address bar so you can see the full URL, every time:

The current address bar appears like the one above.

Step 1: Open Firefox and type "about:config" into the address bar.

Step 2: Click the button that says, "I'll … Read more

BitTorrent offers tech to decongest ISPs' networks

LA DEFENSE, France--BitTorrent, a company that's enabled network-crushing levels of file sharing, can be seen as Internet service providers' natural opponent. But the company's chief executive today entered the lion's den with a surprising message:

"I'm actually here to help."

How? In a speech at the Broadband World Forum here, BitTorrent CEO Eric Klinker tried to build enthusiasm for his company's Micro Transport Protocol, or μTP, an open-source technology that's built into the company's client software for sharing files over peer-to-peer connections. μTP increases network efficiency and addresses congestion--the biggest concern … Read more
