Well who would have thought? The humble old DVD seems to be getting a new kick of life due to some very clever thinking scientists at Swinburne University of Technology in Melbourne. Could the rumours be true? over 2000 movies on one DVD? Well Samsung seem to think so… Read more…
Pipe Networks’ first international broadband cable PPC-1, landed in Sydney last week. The cable stretches 4787km running from Collaroy on Sydney’s Northern beaches to Guam before branching off into other major countries.
The $200 million project which has been in the works for several years has overcome several hurdles along the way. The backing for the cable was originally projected at about $200 million in April 2007 and awarded to Tyco later that year. The project was expected to be covered by a credit facility provided by Westpac and ANZ banking group, but in December last year, just as the project was due to begin, ANZ and Westpac pulled out leaving a hole in Pipe’s plans. The project was rescued by an increased financial commitment from Pipe Networks and a group of ISP’s including Internode, iiNet and Primus who agreed to enter long-term capacity leases on the new cable.
The Wolfram Alpha team has revealed on their blog, some of the impressive hardware behind their super-duper new “Computational Search Engine”. If you haven’t heard about Wolfram Alpha yet, it’s a recently launched “computational knowledge engine” with an interface similar to a search engine. Wolfram Alpha promises to approach to our search engine needs from a different perspective, with the lofty long-term ambition of “making all systematic knowledge immediately computable by anyone”.
By entering your question or calculation, Wolfram|Alpha uses it’s built-in algorithms and ever-growing collection of data to compute your response. Be it the distance in cm to Pluto, or the age old mystery of ‘how much wood would a woodchuck chuck if a woodchuck could chuck wood?’
The Google network dropped off the radar for many Internet users last Thursday. Widespread outages were reported across several Google services including search, Google Docs, Gmail and YouTube, were the main services that left people scratching their heads and wondering what to do next – best catalogued here by the #GoogleFail Twitter stream.
Not all Internet users were affected, but those using larger American providers such as AT&T or Verizon, appeared to be disproportionately effected. A number of larger US based ISP’s “peer” with Google, or interconnect their networks with Google’s networks in order to improve speed and reduce bandwidth. Much like a large-scale highway accident shutting down a key section of road, the effects still ripple off and smaller ISP’s not interconnected with Google were able to route around the problem.
Cacti is an awesome tool for monitoring your network and keeping an eye on your current network status. You can quickly and easily add switch ports and browse your network via a very simple, easy to use web based GUI. However, Cacti uses SNMP and a number of other available methods to determine your network flow.Therefore, in the situation where you have VPS containers, Cacti itself can only monitor traffic by default on switch port where the hardware node is connected.
Here is a quick rundown on how to monitor network traffic by IP rather than monitoring network devices.
Requirements for RoR
There are a few major requirements for installing Ruby on Rails (http://rubyonrails.org/) on a cPanel server. First, cPanel 11 must be running on the server. This can be verified by checking at the version number in the upper right-hand corner of WHM.
Installing Ruby on Rails in cPanel does require some command line interaction, so you will need to make sure that you can log into your server via SSH as root. Furthermore, cPanel requires that your server contain a working yum configuration. You can check this before trying to install Ruby by running yum list ruby from SSH, if it works without error, you should be fine.
So you probably think we’re all sitting back at our desks, day dreaming about the weekend or betting on this weekends football matches but that’s definitely NOT the case. (Go the Roosters!) We’ve been busy making purchases in preparation for our new cloud infrastructure! Gigabit switches, Brand new (and amazingly powerful) Dell Servers, brand new cabinets in the new area of Sydney’s Equinix Data centre, and it’s all coming together rather nicely.
We’ve been busy doing research and development so that we can hit the ground running and we may just be the first Australian host to provide cloud services to the public. And we’re VERY excited about it.
Here’s some specifications of the servers we have purchased, for you personalities out there that have geek or technology tendencies.
Dell PowerEdge R710 servers each with:
Dual Intel Xeon X5550 – 2.66Ghz, 8M Cache, 6.40 GT/s QPI, Turbo, HT (These are the new Intel CPUs with performance improvements which absolutely destroy any previous benchmarks)
72GB RAM – Check out the below photos to see how each set of DIMM slots are assigned to each CPU, which from what I’ve heard – doubles the speed.
6 x 300GB SAS (15,000 RPM) Drives in RAID0 configuration. – Due to the way our cloud infrastructure will work, storage will be raided on the cloud layer so we don’t need to worry about mirroring data at the hardware level.
4 x Gigabit Ethernet ports – At this stage we will be using 2 ports per server, but soon enough we will increasing this to 4 or maybe 6 ports per server for better throughput.
Dual PSU Units – These are awesome, allowing us to actually change power supplies whilst the server is running.
