Normal user privilege problem for using WiMax USB Modem in windows 7

This is my first post from my laptop. From now on I can write from my home. Recently I buy a Dell Core i3 laptop made in china. Please note, I’m from Bangladesh. Here we all enjoy duty free & all kind of tax fee computer peripheral. Thats why we get these technological facilities with cheap rate. Anyway, Its not my issue. After getting laptop I get a connection from our local WiMax service provider Bangla Lion. Their’s modem is USB modem. Its nice after installation and configuration. Problem is for other users of my laptop…

I always like to use computer with normal user rather then administrator user. Here I can impose many restriction for security reason to fight with VIRUS. So, when I login with my another normal user I fail to connect with my provider… I phone them customer support they didn’t get any solution. So, I start R&D for this issue and finally got success for 6 hours. I’m using windows 7 that was with my laptop and off-course pirated copy (thanks MS, really we Bangladeshi techi personnel can’t achieve the latest trend if we don’t get this facilities). So, guys if you face any problem just do following……

  1. Install your modem with administrator account as usual normal installation. Nothing special while installation process.
  2. Now go to the folder where you installed your modem and change security settings
  3. Add your user’s for permit to use modem with read-write permission to that folders & its content’s and sub-folders.
  4. Then go to windows firewall settings and add your modem software permit for both communication of home and public. I know this may cause a security whole if you can’t trust your provider. But if you trust your provider’s software its not a problem at all.

Actually my modem need write permission to that folder. May be some file it modify before starting to program file path. And it can’t write to that path and forbidden to use the modem.

Hope this post will save someone’s 5~6 hours just for 15 mins…. lols

How reduce your image size without losing quality for using profile picture of web page

Many of us worry about our picture that is too big size. Some website didn’t permit big size image to upload as profile picture. Some website has some restriction and limit on file size. You need to determine what type of restriction that website has. There are three types of restriction. They are –
1. File size
2. Image dimension
3. Image type
We will not discuss about image type. Image type may be JPG or GIF. You can read more about these formats on net.
Image dimension consist with width and height that measure with pixel. Other measurement unit exists to measure width and height but we will ignore those unit cause maximum website deal with pixel. For change file dimension you need to use image editing software and you need to have a little bit expertise about image. I just show you how you can reduce or enlarge an image dimension with most common and popular software Photoshop. Please note, I just show you a way to change. There has several ways to change the image dimension. Now just follow the following steps…
Step # 01: Open your document into Photoshop.
Step # 02: Go to “Image” >> “Image Size”

You will get a dialogue box to change image size.

Step # 03: Now in image size dialogue box you need to change “Pixel Dimension”. Before change pixel dimension you need to care about some properties…

  1. Mark check box of “Constrain Proportions”
  2. Resolution of “Document Size” portion can be 96. If it is not 96 then change it to ‘96’. And the unit will be ‘pixel/inch’

Step # 04: Now change your desire width and height at “Pixel Dimensions” area. Please note, you must not touch width and height at “Document Size” area.

Step # 05: Click ok and save your image with default options.

That’s all you saved your image with desire width and height. But still your document is big in size. Don’t worry continue reading you will get a solutions. Ohh, please note, when you change resolution, the image width and height may be change automatically. Doesn’t worry just ignore it! You must follow the steps sequentially i.e. at first check “Constrain Proportions” then change “Resolution” then change dimensions.

Image files size measure with Byte, Kilo Byte, Mega Byte, etc. Most website permit user in Kilo Byte size. If you want to know more about file size then you need to surf net. But for this tutorial you need to know the hierarchy of unit.

Bit ———- unit
Byte ——— its also an unit but its big then bit by 8 times
Kilo Byte ——– big size then byte 1000 times
And Mega, Giga… so on

Now at first you need to check your image file size. It’s easy, right click of your mouse on to your image and click properties. There you will get information of your image file size. If it is less then restricted size then don’t need to read down. Just upload your image into that site!

So, you have a big file sized image! Don’t worry; I’m here to help you. Just follow these steps –

Step # 01: Open ‘mspaint’. Go to start >> click on run

Step # 02: You will get a small box. Type ‘mspaint’ and click ‘Ok’

Step # 03: This command will open Microsoft Piant tools for your service. Open your document.

Step # 04: Now save as the document by File >> Save As. Please choice JPEG from ‘Save as type’ drop down list

Step # 05: Save your image with a different name.

Step # 06: Now check file size again by right click on file and go properties.

It’s done! The size is down dramatically.

Enjoy computing…

ABC on Internet

Introduction

The modern life is very much dependent on communicating with each other. How can we communicate with each other? Various media, like – Sending Mail through Post Office, Sending Message through Messenger, Say Hello by Land Phone or Mobile etc. At the ancient time we communicate each other with Pigeon or Messenger. But in the modern life we like to take advantages of digital technology. Internet is such a digital technology of modern life.

Elaboration of this Internet is “International Networking”. It’s a big network where computers are attached with each other all over the world. We know that, computer can attach with each other and can talk with each other, can share file with each other, can share music, can share video with each other. So, all the computer of the world is inter connecting with each other and makes a big network that virtually act as a big computer for a world. We don’t need to know how they communicate with each other. We just need to know how we can reach other computer that is outside of your computer or outside of your country. So, we can reach our friend’s computer easily to communicate with her.

Cyber café is such a place where you can use computer by paying money. Here all computers are pre-connected with internet. So, you don’t need to connect them. You need not to know how they connected, how a computer can open etc. You just need to know how you can use internet. You need to know a very basic knowledge about keyboard, mouse & monitor. Are you know, how a light is lighten by passing electricity? You just need to know where the switch to on that light is. How this switch is operated? And use this light by switch on. Internet is easy like switch on a light of your room.
Now the things you need to know for switching internet communication, is – Browser, Website, Email Address, Checking & Sending Mail, Searching or Surfing Internet for Information etc.

So, what about operating procedure of a computer? Nothing, we need not to know! Well, let me explain. When we were 2 years old, are we know about all the stuff of our room? No, not at all. But, we recognized the toy by which we can play.

About Browser & About Form

Now the most important part to use internet is browser. I like to compare browser as our “Table”. Where we can put our book for reading. It’s such a place where we can put our writing pad on it and write. So, it’s a workstation where we do our regular duties, isn’t it?

Now, what is the category of the table? Is it furniture? Yes, its furniture. In computer we can categorize “Browser” as program. If we think a computer like our room, then browser is a type of furniture like table.

Now, we already hear a word “website”. What does a website means? Website is such a place where certain information is written and can access from anywhere of the world through internet. Now, what types of information are written to the website? It’s may be the details of a product, about a place, any instruction etc. Well, let’s consider an example. Someone wants to know about “Sundarban”. Someone wants to know how he can reach to “Sundarban”. Now, if we can written all the information about “Sundarban” and put it a such open place from where anyone can access to that place and can read about “Sundarban” then she easily get all the answer about “Sundarban” from that place. That such place we call “website”. Now, what happen, if we can publish a book on “Sundarban”? Write all the information about “Sundarban” into that book. And keep that book on our table and read! Exactly, we compare our website as like as book. Where information is stored and people can read it by putting it on the table. It makes some sense about the relationship between browser and website, isn’t it?

Now, what about form? Form is nothing but a predefined question paper that need to collection information for a certain purpose. If you go to admit a school your parent need to fill up a form about you and your family. That form contains your name, your father’s name, mother’s name etc. etc. In that form we need to write but here at web form we need to type information by keyboard. After writing that form we need to submit it to school authority by handing over the filled up form. Here we need to submit it through a button that we call “Submit Button”. Its simple, we just need to know about the parts of the form. The main parts of a web form are – Text Box, Text Area, Select Box Multiple & Single, and Option Box Multiple & Single. No need to worry about form in this time. You will be familiar with web form while use net regularly.

About Mail Server & Storage Technique

As we already know that we have a common place where we preserve information for public access that is called server. We can store our information as webpage into server. Also we can store mail into that server.
Well, let’s consider a scenario. One of your friends wants to send a message through courier service. He will write a letter then go to courier service to post it. The courier service authority will send that letter to your friend’s city branch of that courier service. Then the postman will search you to give you that letter. If you don’t at home at that time the postman will drop it to your home. When you come to your home you will get that letter of your friend. Here server is act like as your home. All the mail is stored into server until you read it.

About User ID & Password

I’m trying to make you understood with some real life example. It will help the issue to understand easily. Now think you admitted into a new school and meet with your new friend. There you found that there has another friend who has the same name of you. Suppose your name “Mithila” now what other identified you? Its simple, they make a new name of you like “New Mithila” or something else. And it’s your identity at your school. In server the unique name is called “User ID”.

Now what is password? It simple, it’s a secret phrases that only known by you! Now why you need password? Basically computers don’t know you. It’s a machine. So if your friend claims that her name is “Mithila” then what happen? Cause you and your friend Mithila are using same computer. So you need a secret word or code to claim your uniqueness, isn’t it? That’s password need.

Mail Header / Parts of Mail Message

Mail header is the information about mail. You all know about traditional letter. In that letter you will find from whom you receive that letter and when you received that letter. This is called the information about letter. As like as every email have this information. We called those information as “Mail Header”.

Now what about a gift? Suppose your elder brother send a nice gift like a “Barbie Doll” to you. What you think, isn’t it nice? Your elder brother may send that gift and write a letter to you. Now what is the scenario? You getting letter with a gift. Here in electronics system we have same approach. Suppose we need to send a song with a letter. What can we do? We just need to attach that song with that email. And that is called “Attachment”. It’s also a part of email.

Now you have two another term of email header, they are – CC & BCC. CC means Carbon Copy. You all know about carbon. When we need a document more then one copy for preserving purpose or another purpose we use this carbon to copy it. In the modern technology we can photocopy that document as much as we need. So, what about CC? When you need to send your same mail to many of your friend then you need to use this option. Suppose you want to send “Eid Greetings” to your entire friends. What you will do? You will type your message and send to a friend. For another friend you need to type again and send it to that friend. May be you can copy the message text for sending the same message. But with CC option you can send the same mail to as many as you can. Just type the friends email address separated with comma and send it. It simple! Now what about BCC? You don’t need to use this BCC option now. Its elaboration is Broadcasting Carbon Copy. Its same as CC but with little functioning difference. You can use it as CC. You will learn it by using I think.

About Yahoo Profile, Yahoo Mail Account & Address Book

Yahoo profile is a profile that keeping by Yahoo. Information about you is kept by Yahoo called Yahoo Profile. In the profile it contain your name, from where you from, from where you surfing or accessing the site etc.

Yahoo Mail Account is a space where your mail stored. If someone sent you mail the mail will stored into that area until you read it. You can also store it permanently in to this account. It’s also an identification to reach you or to send you email.

Address Book is the register of email address. In this book you can save your friends email address for future use.

About Search Engine

Search engine is a special site where you can find the address of your desire word. Suppose you want to know about “123 Sisimpur”, but you don’t know where you can get information. So, first of all you need to search the address related on “123 Sisimpur” then you can go to that website to get the information about “123 Sisimpur”. From which you get the address by searching them we called it search engine. Those search engines is maintain the name of all other website. The search engine will provide the list of website that is related with your keyword. You need to put your keyword into specific text box to search. After getting the list you can easily find out your desired website.

Conclusion

Internet is easy to use & very cheap communication facilities with each other. But its global. The main fact of internet defend our real life is, if we have a permanent address we can use it to get any letter from our friend. But when we are on travel, then how can we get those letters instantly? But with email address we can get mail from anywhere anytime.

Disclaimer:

This article is written for a primary concept on internet who have no idea about internet. Basically I’m trying to establish a relationship between our real lives with internet. Internet is a vast subject. It’s not possible to give a greater knowledge at the very first time.
