How to Install FreeNX Server and Client in Ubuntu 9.10

FreeNX is a system that allows you to access your desktop from another machine over the Internet. You can use this to login graphically to your desktop from a remote location. One example of its use would be to have a FreeNX server set up on your home computer, and graphically logging in to the home computer from your work computer, using a FreeNX client.

Installing the FreeNX server on Ubuntu 9.10 (Karmic)

Open your terminal from Applications->Accessories->Terminal

Run the following commands

sudo add-apt-repository ppa:freenx-team

sudo apt-get update

sudo aptitude install freenx

Now use nxsetup to install necessary files and create the special user “nx”

sudo /usr/lib/nx/nxsetup –install

FreeNX Client installation in ubuntu 9.10 (Karmic)

If you want to install opensource client for freenx use QTNX,QTNX NX client for QT install qtnx using the following command

sudo apt-get install qtnx

Install Freenx client in windows

You can download freenx windows client from here and install.

Twitter Will Soon Be Using Bittorrent Technology for Servers

Large scale web-services such as Twitter need thousands of servers to manage the flow of updates that are sent out by their millions of users. As a result, keeping all these servers updated with the latest data can be time and resource intensive.

To improve the deployment of files across their servers, Twitter is calling in the help of BitTorrent. With BitTorrent, Twitter is planning to distribute files faster and more efficiently, saving time and precious resources and improving the scalability of Twitter’s operation.

Twitter’s new project, codenamed ‘Murder’, will not use the bandwidth of Twitter users. Instead, it will transform the site’s servers into a large BitTorrent swarm that will distribute file updates using BitTorrent technology.

The setup is pretty straightforward. Murder uses a ’seeder’ server where the new files will be distributed to thousands of ‘peer’ servers.

Because all servers assist in the deployment of the files, it will only take a fraction of the time it would otherwise take when files are distributed from a central server. This server-to-server BitTorrent technology also explains the name ‘Murder’ which is used to describe a flock of crows.

The Murder project is developed by Twitter’s Larry Gadea and built based on the BitTornado BitTorrent client, which was the first client to implement web-seeding. The code is open to the public and licensed under the free software Apache License.

Eric Klinker, CEO of BitTorrent Inc. is excited about Twitter’s adoption of BitTorrent. “We are thrilled to collaborate with them on this and hope that more Web Monsters out there look to this and other applications of BitTorrent in solving some of the hard problems of the Internet,” he said.

“The distributed nature of BitTorrent means an operation that once took many dozens of minutes, now happens in less than a dozen seconds. These efficiencies will reduce maintenance windows, site downtime and exposure to security vulnerabilities,” Klinker added. Although Klinker speaks about “collaboration” with Twitter it is not clear what role BitTorrent Inc. will play in the Murder project.

At this point it is still unclear when Murder will be implemented or released to the public but Twitter is expected to release more details on the upcoming project in the weeks to come.

Bill Gates’ New Website The Gates Notes Runs on a Linux Server

It has been reported over at Techcrunch that Bill Gates’ new site The Gates Notes, was running on a Linux-powered server. This would be ironic since Gates is of course the founder of Microsoft, which is Linux’s biggest competitor in the server market. It would be the equivalent of catching Gates or CEO Steve Ballmer being caught using (and not just signing) a MacBook at a conference.

A quick search on Netcraft shows that thegatesreport.com sure enough looks to be running on the Linux OS. But wait. The results also say that web server is Microsoft-IIS/7.0. That doesn’t sound right, so what gives? Well, it turns out that because Gates is using Akamai to mirror his sites’ content in the event of massive traffic (or more specifically, something like a DDoS attack), this data is being filtered through there. Akamai uses Linux for its servers, so that’s what OS is being passed back to Netcraft. But at the same time, to make things more confusing, the Akamai servers are still passing back the correct server header for Gates’ site: Microsoft-IIS/7.0.

How do I know this? Because the same thing happened in 2003 when it was humorously, but erroneously reported that Microsoft was using Linux servers to run microsoft.com. In fact, the same thing was going on: Microsoft was routing its traffic through Akamai, which again, runs Linux boxes. Microsoft has since apparently changed to its own servers since then so that they now correctly return Windows Server 2003 as their OS. That is likely what The Gates Report is running on as well given the Microsoft-IIS/7.0 web servers.

Airstash: Wireless SD Card Reader

airstash This is definitely one of my favourite products of 2010 and the year has just begun. It’s a wireless device which allows you to insert an SD card and read it on your PC or mobile phone as thou it were connected via a USB cord. This would be excellent for photographers who need to easily transfer files from their SD cards and indeed those who transport SD cards around with them containing important files frequently.

airstash 2

It’s called the Airstash and is targeted at iPhone users because of it’s portability. However it uses WiFi and as such it can be used in conjunction with any other WiFi enabled device or laptop. It is small, weighs very little and supports cards up to 32Gb.It also acts as a WiFi access point. Unfortunately, the fact that it must be accessed via a browser means that you loose your Internet connection when using it. It can also be used as a USB device. However, in my book, so long as it’s not ridiculously over priced (we’re expecting an RRP to be released in a couple of months) then I think I’ll be buying one!

This website gives you the chance to test you website for performance by entering the few details as seen below in the screenshot.

test URL 1After hitting the submit button it takes a minute or two to finish testing your website. After this you get some great results such as showing you which type of content is causing delays (ie. Images, Java) so you can remove or compress them. And things like SEO and server response time.

IDG Tech Network Leave Adify and Move To DoubleClick

IDG Tech Network is moving away from Adify and Doubleclick will be their new ad serving and technology partner. IDG confirm that everything will be moved to Doubleclick between the 12-19th of February and that the transition will be a smooth one.

Adify have not really been making too much improvements since they were acquired back in April of 2008 for $300 million by Cox Enterprises. It is interesting that IDG have moved from Adify to Doubleclick. I know Doubleclick are quite an expensive ad serving solution compared to most on the market today, but this move has happened because Adify are even more expensive. Adify have been charging around 20% or net revenues from networks who have been using their platform. This is extremely high and no wonder they are losing business. IDG has to be one of Adify’s main customers so this is a heavy blow.
