Facebook Graph Search

by Ruchira on February 21, 2013

facebook graph search

Facebook’s graph search is slowing reaching out the people who opted in for the trial. Today it got enabled on my account and I got really excited to try it out. But my initial impression about the interface is not really good. Maybe its because this is just a trial run before phasing out for the whole user base, but when concerning about the UI I think facebook should have done better than this.

I made the switch to Ubuntu

by Ruchira on February 20, 2013

linux 2013

 

 

Managing servers and messing with Unix like environments is my day job. However I have been using Windows on my desktop since the Windows 98 era. I have got a free Ubuntu 4.10 (Warty Warthog) way back in 2006 but it wasn’t exciting to me on those times. Those were the days people were rocking dial up connections and couldn’t afford to download that extra codecs required to run MP3s and Video files. So first impression was negative with Ubuntu for me. Later on I have tried many Ubuntu versions on live CD’s etc but I never got convinced to make the switch to Ubuntu as my primary desktop operating system. And the availability of software’s are limited.

Nvidia announces Tegra 4i with inbuilt LTE

tegra 4i

 

 

Nvidia just announced the Tegra 4i processor which got integrated LTE chip on processor SoC. This is really good news because we all know that having to run separate LTE chip increases the power consumption and decreases all over efficiency because of many constraints by having to transport all the communication data in and out from the SoC. When Nvidia announced the original Tegra 4 which I covered here  it also didn’t included a integrated LTE chip but they have detailed i500 soft modem which OEM’s can integrate (separate chip) to Tegra 4 to enable LTE functionality.

Tegra 4i comes in built with that i500 chip reducing the constrains of having to run the i500 outside of SoC. However the architecture of cores and graphics cores are different from the original Tegra 4 as the Tegra 4i is an Cortex R4 A9 processor unlike the A15 Tegra 4 sibling. And GPU cores on 4i count at 60 where as Tegra 4 has 72. Nvidia went with A9 because to reduce the power consumption and to reduce die size

MEGA which is Kim Dotcom’s successor to MegaUpload seems to be gaining traction on Cloud storage market very quickly. I have personally tried MEGA and its great for storing personal data on the cloud. It gives you 50GB for free and latest 2048bit RSA encryption makes your hosted files safe from intruders. But what about mobile Apps? While MEGA is saying that IOS and Android apps will be out soon, third party apps have been emerged thanks to MEGA’s fully functional API.

How to install Packet Tracer on Ubuntu

by Ruchira on February 12, 2013

packet tracer on ubuntu

 

Cisco Packet tracer is a nice way to emulate cisco networks if you are studying for any of cisco certifications. But did you knew that its also available for Linux ? Installing Packet Tracer on Ubuntu or any linux platform is very easy.  Packet Tracer is available to download on Cisco Academy Connection web site eventhough its free, you will need an account to download it. You have to go though a cisco academy partner to get an account there and if you are just a self learner its impossible for you to get a account. But I bet you know how to get it by some other ways and I’m not going to talk about that here 🙂

Lets assume you have obtained the latest version of packet tracer which is 5.3.3 (PacketTracer533_i386_installer-deb) , you will get a .bin file and put it on your Home folder.

I have written many guides on how you can setup proxies and VPN tunnels to access the country restricted web sites such as Hulu,Netflix,Pandora,BBC Iplayer .  However those things comes at a cost and average internet users wont like to make their own VPN or Proxy. And another limitation of those is we need to have 2 servers in USA and UK to get access for all of above sites. Because if you only got a VPS based on USA and setup VPN on it, you wont be able to get in to BBC Iplayer. And if you got a UK based VPS you wont be able to access hulu,netflix and Pandora. So this is a costly solution
