+ - How Slashdot Inspired Our New Redundancy Feature->

Submitted by agizis
agizis (676060) writes "In October, there was an 'Ask Slashdot' post, wondering how to use a VPN, "so that the same TCP and UDP traffic goes over both links, and the fastest packet on either link 'wins' and the other is discarded?" At the time, there was no good solution. Thanks to Speedify's new "Redundant Mode, this is now possible. By sending UDP traffic over every link, Speedify really can drop average latency significantly. Your opponents in Battlefield won't stand a chance!"

+ - Amtrak WiFi Reliability (And How to Improve It)->

Submitted by agizis
agizis (676060) writes "Most Amtrak trains now have complimentary WiFi. Unfortunately, the connection is often unreliable and slow. I wanted to understand (and graph) the Amtrak WiFi experience. So I grabbed a couple network cards, and rode from New York City to Philadelphia. Using a Python script from my laptop, I ran speed tests every 2 minutes..."

This is Alex from Connectify. Sorry to hear you weren't happy. We put out a new release *yesterday*, with huge improvements on how both loss and jitter are handled. Since you have both, I think this could fix your issues. Assuming that you are who your slashdot profile says you are, I just emailed you another license. Please give us another try, we're here to support you. New software here: Thank you for considering Speedify.

A MPTCP VPN would not work in the real world. When you tunnel TCP through it, you end out having to send ACKs for the ACKs. The end result is that the effects of even a tiny bit of packet loss is a performance meltdown: To build Speedify, we needed to implement a new multipath protocol over UDP. But that let us do clever stuff with NACKing and retransmitting lost packets before TCP ever noticed, and we were actually able to reduce the effect of loss:

Hey, thanks for the mention. This Alex from Connectify. We've launched a new VPN service called Speedify that combines multiple network connections. It's very smart about jitter and retransmitting lost packets. I think it's exactly what the OP is looking for:

Hey, sorry for the hard sell, but this is exactly what Speedify does. It's a VPN that uses multiple connections. It also detects, and retransmits lost packets long before TCP notices. Latest beta has been tested on Amtrak trains combining their Wi-Fi with Verizon 4G. Please check it out:

Ha, that's exactly what I thought when I started implementing it. But it turns out it's way harder than it appears. Differences between internet connection in latency, loss,bandwidth, jitter, and buffering all conspire to make this a very difficult, multiyear project. That said, we've done it already and put servers all over the world, so you can just sign up and use it. Speedify:

This is what we do with Speedify: it's a VPN that uses all of your Internet connections at the same time. By the time we started dealing with issues like jitter and loss the level of effort exploded into years. That said you should check it out:

+ - World's First 3D Printed Castle is Now Complete - On to Printing a House Next->

Submitted by ErnieKey
ErnieKey (3766427) writes "A Minnesota man, named Andrey Rudenko has officially finished 3D printing a castle in Minnesota. It is constructed using a 3d printer that extrudes a concrete mixture in 10mm high layers. The project took a couple months to complete, and the results turned out quite incredible. The castle's turrets were printed separately, and it took 7 adult men to lift them and put them on top. With his method now proven, Rudenko now plans to 3D print an entire 2-story home, in one piece, including the roof."

+ - Amazon sold fewer Fire phones than Jack White sold VINYL records->

Submitted by McGruber
McGruber (1417641) writes "Marketwatch reports that Amazon likely had sold fewer than 35,000 Amazon Fire phones in the device's first 25 days on the market. In comparison, American musician Jack White sold 40,000 copies of his Lazaretto album on VINYL in the first week after its release in June.

Amazon's Fire phone made up just 0.02% of market share in July, according to online ads network Chitika, which analyzed tens of millions of smartphone-based online ad impressions generated within the Chitika ad network from July 25, the day the Fire was launched, through Aug. 14. When comparing that against recent data from comScore, which put total U.S. smartphone penetration at 173 million people in June, Fire sales would not have exceeded 35,000 in its first three weeks, assuming U.S. smartphone penetration remained relatively flat month-over-month.

"While the Fire Phone was listed atop Amazon's Best Seller list for several days in early August, North American usage of the device has grown only incrementally, rather than exponentially," Chitika said in a report."
