Submission + - The 2016 Ig Nobel prizes are here. VW wins the prize for chemistry! (

whoever57 writes: The 2016 Ig Nobel prizes were awarded yesterday, Thursday, September 22. Notable amongst the winners was VolksWagen, who won the Chemistry prize for "solving the problem of excessive automobile pollution emissions by automatically, electromechanically producing fewer emissions whenever the cars are being tested." No one from VW attended the ceremony to collect the prize. Other notable winners included a team who won the Peace Prize for their groundbreaking work analyzing the detection of "Pseudo-Profound Bullshit."

Submission + - 26th First Annual Ig Nobel Awards Awarded (

REPRODUCTION PRIZE [EGYPT] — The late Ahmed Shafik, for studying the effects of wearing polyester, cotton, or wool trousers on the sex life of rats, and for conducting similar tests with human males.

ECONOMICS PRIZE [NEW ZEALAND, UK] — Mark Avis, Sarah Forbes, and Shelagh Ferguson, for assessing the perceived personalities of rocks, from a sales and marketing perspective.

PHYSICS PRIZE [HUNGARY, SPAIN, SWEDEN, SWITZERLAND] — Gábor Horváth, Miklós Blahó, György Kriska, Ramón Hegedüs, Balázs Gerics, Róbert Farkas, Susanne Åkesson, Péter Malik, and Hansruedi Wildermuth, for discovering why white-haired horses are the most horsefly-proof horses, and for discovering why dragonflies are fatally attracted to black tombstones.

CHEMISTRY PRIZE [GERMANY] — Volkswagen, for solving the problem of excessive automobile pollution emissions by automatically, electromechanically producing fewer emissions whenever the cars are being tested.

MEDICINE PRIZE [GERMANY] — Christoph Helmchen, Carina Palzer, Thomas Münte, Silke Anders, and Andreas Sprenger, for discovering that if you have an itch on the left side of your body, you can relieve it by looking into a mirror and scratching the right side of your body (and vice versa).

PSYCHOLOGY PRIZE [BELGIUM, THE NETHERLANDS, GERMANY, CANADA, USA] — Evelyne Debey, Maarten De Schryver, Gordon Logan, Kristina Suchotzki, and Bruno Verschuere, for asking a thousand liars how often they lie, and for deciding whether to believe those answers.

PEACE PRIZE [CANADA, USA] — Gordon Pennycook, James Allan Cheyne, Nathaniel Barr, Derek Koehler, and Jonathan Fugelsang for their scholarly study called "On the Reception and Detection of Pseudo-Profound Bullshit".

BIOLOGY PRIZE [UK] — Awarded jointly to: Charles Foster, for living in the wild as, at different times, a badger, an otter, a deer, a fox, and a bird; and to Thomas Thwaites, for creating prosthetic extensions of his limbs that allowed him to move in the manner of, and spend time roaming hills in the company of, goats.

LITERATURE PRIZE [SWEDEN] — Fredrik Sjöberg, for his three-volume autobiographical work about the pleasures of collecting flies that are dead, and flies that are not yet dead.

PERCEPTION PRIZE [JAPAN] — Atsuki Higashiyama and Kohei Adachi, for investigating whether things look different when you bend over and view them between your legs.

Submission + - Bonding Wi-Fi and Cellular on a Phone (

An anonymous reader writes: Lifehacker reports: Speedify is a handy way to combine multiple internet connections into one mega pipe. Now, in 4.0, you can send redundant data over multiple connections, and get started without an account. If you’re on a VoIP call and you want to make sure it doesn’t drop, you can place that call over Wi-Fi and cellular data. This way, if one drops, the other will pick up the slack and you won’t notice the difference.

Is it really possible to combine connections like this on a phone? Shouldn't this break your TCP sockets?

Submission + - How Slashdot Inspired Our New Redundancy Feature (

agizis 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!

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.

Comment Re:mptcp (multipath tcp) is one solution (Score 2) 174

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, 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:

Comment Re:Actually, it's easy. (Score 1) 174

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:

Comment Re:Neat idea, but not worth the effort (Score -1, Redundant) 174

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:

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

ErnieKey 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.
