Introduction to DNS systems.
Feb 26th
What do you mean by DNS? Simple answer is Domain Name Servers. How they work?
Well the best choice to explain this is telephone directories. Imagine that you wan to call some one and you know his/her name but not telephone number. So you need a telephone directory to find his/her number. So you can flip the papers of the directory and search for his name and then find the telephone number you need to know.
DNS service acts same like the telephone directory in your home. When you type www.google.com or any web site address in your browser Internet service need to find the ip of the server where google.com situated. So your computer makes request to find the ip address of the google.com from DNS servers. So DNS servers gets the request and then forward us the ip of the web site you need to go.This process works inside of your computer network so you dont get any visuals of ips.
Typically Internet Service Providers operate their own DNS servers for their customers. They are automatically assigned to your computer if you not manually edit DNS options in your computers network settings. But you can change DNS servers if you like to get more accurate and fast web browsing.
Imagine if your telephone directory is old and un-arranged it takes more and more time to find the phone number. Like the same process the quality of your ISPs DNS server directly affect your web browsing speed. This doesnt means the downloading speed.Slow download and upload speeds doesnt mean your DNS bad.
Come again to the theory of the telephone directory. When you have un-arranged directory it takes more time but it doesnt affect the quality of the call that you make to other party. If you have well arranged telephone directory it takes seconds to find the telephone number but you gets the same quality of the call like previously said.
Bad DNS servers makes slight delay when you request for a web site.
In my next post Ill explain how to optimize your DNS system to be more accurate and Ill do a brief benchmark of newly introduced Google DNS system. SO wait……………….

I think you know the meaning of locked dongles. That means that dongles locked for using one career which you bought the modem from.
There are various unlocking methods to use 99% of them costs more than $10 . In this method you didnt require to buy anthing from anywhere but you needs to register on the forum http://forum.gsmhosting.com/vbb/ to obtain your unlock code from one of their members. Im 100% sure that you will get your unlock code within 15 minutes from their member base. There are unlock code calculaters which can be used to obtain codes easily but they are not 100% accurate some times so its risky to try them some times because if you enter unlock code wrong more than 10 times the modem will lock permanantly So you it will need some advanced operation to remove that lock. So I presume you registered on the forum now.
After registering there go to the thread http://forum.gsmhosting.com/vbb/showthread.php?t=781410 Please do not ask for unlock codes in other threads because that thread is the only place to ask for codes.
On that thread place new post mentioning your modems model ex- Huawei E156G (which I tested) And your IMEI number (you can see that on the housing of the modem)
Ex post-
Please help me to unlock my modem
Model- Huawei E156G
IMEI- 359390*********
Usually withn 10-15 minutes you will get unlock code from some member there in reply to your post -
Ex-
Voila. After obtaining your code download this simple software to enter the unlock code to your HSPA modem- Download it here – http://www.sagmaster.com/download/10SMTi/HUAWEI_MODEM_Code_Writer.rar
Then run it-
Click detect and slect your modem from list then click accept.
Then click Unlock Modem and enter your 8 digit unlock code that you got from the forum members-
Then click ok. Whopas Its done. Next post will be about activating hidden voice calling feature for free in many huawei modems. Enjoy your unlocked modem and use it wisely.
Am I dead?
Feb 22nd
Hi fellas,
First of all this is a surprise for my readers because I’m back after a long long time to write the buzz again. voila. What are the odds of being offline for months?
Well I think I have answers for all of the questions that I faced till now. The main reason is I used to run a web hosting company past months and its profitable but its a pain some times because I need to be online most of the times to answer questions of my clients and resolve them. I managed to keep the hosting servers mostly online 99% ( Well I didnt used shared accounts like most do 
I used to manage my own servers to host clients ). And the main purpose of the host is to host high traffic proxies. So Its very hard job because I have to keep my on the servers all the time because high loads. Some sites on the network consumed more than 100GB traffic daily . So it was more hard because one single mistake can lead the whole customers down.
And I have one major exam in my life in this year so my life became more complicated . Finally I decided to sell the hosting company to another hosting company in Canada. They bought my clients and company for great price and my one and only condition was to keep clients happy and bill them low profile like I used to do.
I learnt lots of things in this journey. To manage a business,to build a happy client base,to manage high traffic servers specially 
And finally Im available again to blog like before. So this will be new start to the www.ruchirablog.com and lots of updates coming.
Don’t forget that now this blog is page rank 2 (Even with 0 link building in past 6 months) You can comment in my post with your web site URL and what you get in return is page rank 2 back link for your site so enjoy.
Secrets of “How to” blogging for SEO traffic
Oct 18th
Have you ever wondered why Im blogging most of my articles with “How to ……” in the title ?
Examples-
- How to setup VPS or dedicated server with a kloxo admin panel
- How to get adsense account fast
- How to get higher pagerank
The simple reason is to get maximum of search engine traffic mainly from google. Because most of people searches “How to…………. ” on search box.
For an example think one wanted to know how to brush his teeth correctly. Then he googles for that phrase “how to brush teeth correctly.” Instead of “Brush teeth correctly”
As a intro webmaster and blogger im mainly focusing on google traffic because I dont trust on yahoo or bing. Because I never succeeded with them. So google indexes your results on top if your content is good and your title is good. Yes title for post on a blog is very important for SEO.
So just follow this tip and see the difference in traffic increasing in yourr tracking tool and earnings. 
Free web proxy to surf blocked sites
Sep 24th
Most of the people who works in offices and learn in schools face the trouble of internet browsing because many of web sites blocked from access. Like facebook,youtube,bebo etc. So if you face the same problem you can use www.hidehead.com to browse without restrictions. All you have to do is go to and enter your destination url (the web page you want to browse without restrictions) and click GO button and it will take you to the blocked web page without problems. There are many web based proxies but they are damn slow because of hosting on shared hostings like that. But www.hidehead.com uses dedicated server to bring on the horse power. So enjoy unrestricted web browsing with www.hidehead.com
ATI HD5870 Photos and Benchmark leaked
Sep 10th
here goes another leaked post! lol This is interesting AMD is going to rule the computer world. Few days ago AMD 12 Core processors rumored now yesterday 09th September few photos of AMD’s upcoming VGA card named HD5870 Photos leaked and one dude posted a crysis benchmark. Previously fake photos of HD5870 leaked and most probably they are edited from the pics of HD4870. But these pictures can be 99% possible images of reference engineering sample. So here goes them-
source-Tweakers.net forum.
Crysis benchmark-
HD5870 Crysis Benchmark scores (core frequency is higher than the retail version)
CPU:AMD Phenom II X4 955BE CPU: AMD Phenom II X4 955BE
Win 7 RTM Win 7 RTM
VGA:HD5870 1GB VGA: HD5870 1GB (core frequency is higher than the retail version)
Crysis 1900×1200 4AA+16AF DX10 Very High Crysis 1900×1200 4AA +16 AF DX10 Very High
min:30.** min: 30 .**
avg:43.** avg: 43 .**
max:54.** max: 54 .**
source-chiphell forum.
So this most possible benchmark says that Crysis got OWNED by AMD’s new beast HD5870 . But Nvidia’s GT300 series yet to come and will see how the competition goes!
AMD 12 Core Processor CPUZ screen shot leaked!
Sep 9th
On Tuesday, Intel launched its “Lynnfield” processor family, part of the company’s effort to bring its Nehalem architecture to low price points. The launch includes the first Intel Core i5 processor.
The launch includes three quad-core microprocessors: the Core i7-870 and Core i7-860, as well as the Core i5-750. All of the new Core i7 and Core i5 parts will be paired with the Intel P55 chipset. Intel also launched six Xeon processors in the family for workstations and servers.
But suddenly :O :O AMD’s possible 12 core processor CPUZ validation screen shot leaked in to the media.
The CPUz validation calls it a K10 but does not list anymore details including the process size. For some reason it shows as 0nm. As far as current information goes this should not be any smaller than 45nm as AMD/ Global Foundries has not managed to produce a 32nm sample CPU as anyone think or known. But who knows AMD might be had success building 32NM or lower. So this news might be annoying to Intel because this information about AMD leaked on Intels launch of important products to market and the company. But lets see how this battle goes.
