Haunted A Complete Stranger’s House Via The Internet

Posted on by

Their systems had been made crawl-able by search engines – meaning they show up in search results — and due to Insteon not requiring user names and passwords by default in a now-discontinued product, I was able to click on the links, giving me the ability to turn these people’s homes into haunted houses, energy-consumption nightmares, or even robbery targets. Opening a garage door could make a house ripe for actual physical intrusion.

TCP ex Machina

Remy is a computer program that figures out how computers can best cooperate to share a network.

Remy creates end-to-end congestion-control algorithms that plug into the Transmission Control Protocol (TCP). These computer-generated algorithms can achieve higher performance and greater fairness than the most sophisticated human-designed schemes.

Alcatel-Lucent Breaks Record with 31Tbps Over a Single Fibre Optic Cable

The experiment itself, which was carried out at by the firms R&D focused Bell Labs division on the Innovation City campus in Villarceaux (Paris), is understood to have used 155 lasers. Each laser was operating at different frequencies and carrying 200Gbps of data (single-carrier data channels) over a 50GHz frequency grid.

Normally such signals suffer from distortions and noise, which limit performance, but it’s understood that Alcatel-Lucent were able to resolve this by using an enhanced version of Wavelength Division Multiplexing (WDM) that works by splitting light up into different wavelengths so that it can carry more data (a variety of other methods were also used).

Amazon AWS Route 53 GEO DNS Configurations

Posted on by

You can send visitors to different servers based on country of their IP address using Amazon Route 53 cloud based dns server. For example, if you have a server in Amsterdam, a server in America, and a server in Singapore, then you can easily route traffic for visitors in Europe to the Amsterdam server, people in Asia go to the Singapore server and those in the rest of the world be served by the American server.

In this post, I will explain how to configure and test GeoDNS using AWS Route 53 service.

Google making the Web faster with protocol that reduces round trips

An FAQ and an in-depth design document provide more information than most people would want to know about QUIC. Besides running multiplexed connections over UDP, QUIC was “designed to provide security protection equivalent to TLS/SSL, along with reduced connection and transport latency,” the FAQ states.

Rackspace Adds Brocade’s vRouter

Posted on by

The vRouter is a software-based router that runs on server hardware, so it can do other things — routing (duh) or acting as a virtual private network (VPN) gateway, for instance. The attraction to the firewall piece is that cloud customers previously had been building things like firewalls out of Linux components, says John Engates, Rackspace’s CTO.
