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…

Be organized: File Name Convention and Digital Storage Organizing Tips

When I’m at class IX, that time I take a crash course for good hand writing. But today I do most of my job at my PC where no hand writing is needed? Is it a wasted of time that everyone value?

Do you do a lot of work with documents that constantly have to be saved? Well, if you do, you should know that the first time you save a file, you should choose a “file name” for it to be stored under. Note that some programs will automatically put a file name in for you, but it is much better if you name your own files. That way, you have a better chance of finding them later on.

The first time you save your work, you should use the Save As command to tell your computer what “file name” you want to save your work in. (In some programs, if you use the Save command, the first time you save, it will act as if you clicked on the Save As command anyway, but this is only in some programs. So, all in all, you should develop a habit of using the Save As command the first time you save a new file). The Save As and Save commands are usually under the File menu as well.

So, when you are typing a new document in your word processing program, the first time you go to save it, click on File to bring the menu down and then click on Save As to bring its dialogue box up. In the Save As dialogue box, you can tell your computer where to put your file and what to call it. I won’t get into where to put your file here, except to say that if the computer is putting your files in the My Documents folder, that is fine for now. You can always go and change it later.

Another point is for file extension is; many OS hide the file extension for normal user. It’s a good practice to show extension all the time so that you know by which program is best suit for open that file by analyzing extension.

Next, you have to tell your computer what “file name” to save your file under. You should name your file according to what is in it. For example, if it is a letter to your son, John, call it “Letter to John.” Don’t just name it “Letter.” That is too vague.

Here are some examples of good file names:

2009 Taxes for Bob Smith
Personal Budget 2008
Car Prices 2009
Investment Notes from June 2007 Course
Daily Weight for John Starting March 2008
To Do List

Please note: Careful about to do not use periods, especially at the end of your file names.

Here are some examples of bad file names (the problem is listed beside each one):

John This does not say what is in the file (if this is a letter, calculations, genealogy information, etc).
Letter This does not say who it is for.
Letter to John. This has a period at the end of it, which causes problems.
To Do List March 20/09 This file name has a slash ( / ) between the 20 and the 09. The computer will not accept this.
Letter to “Mom” The quotes around Mom will not be accepted by the computer.
Interest * Principal – List of Payments This file has an asterisk ( * ) in it, which the computer will not accept. The dash ( – ) is okay.

So, rather than memorizing all the details and risk having a problem, keep it simple. When you name a file, use only letters and/or numbers, with no punctuation marks. This will make everything easier on you and on your computer!

When create a file that is personal; Start them with your initials (i.e PR: Pronay Rozario) also do the same for important Personal file folders. It’s extremely easy to find your personal and important files by searching for your initials. One more thing…if you create any general use folders, you know the name initials of that folder. If you want to delete it, it’s easy!

When I’m thinking to find files from my colleague’s computer I’m very much scared that I can find it. A well organized file system may work easy for all to find important file from other’s computer. This is not only important for one who uses that computer but also for one who want to help him when he is out of office or at leave. And for common PC this is extremely important, isn’t it?

You need to remember following point to organize your folders –

  • Other users need to find the entire required file quickly.
  • You want to search your required file from archive.
  • You may guess file location for particular working file and find it to that location.
  • You may backup your data for safety purpose.

For above reason you may want your entire file into a common place that is easy to backup and find. Also it’s easy to other to find to that location.

For a well organized file system you may divide your entire file system into category. The basic category I can suggest – Work, Personal, Important Collection, Entertainment, Archive or Past Work, Others etc. I’m always kept a folder named others. In this folder I like to put those file which has no head or name or category, temporary file that might need to save for a limited times. I like to use drive for each root category. If you have not enough drive into your system or you use flat system like Linux or Unix you can create folder into root directory or to that drive you use for store data. I don’t like to use system directory for store data.

Here are some tips to organize your computers files and folders:

  1. One place for all: For many reasons, it’s smart to take advantage of the Documents feature (called My Documents in Windows XP and earlier versions) in Microsoft Windows but I don’t rely on this because it placed into system directory or system drive.  But it’s important to keep the entire document into a central place to take following advantage –
    1. Find files. It’s easy for indexing by OS to provide search result if you keep your file in one place.
    2. Back up files. You should back up files regularly—and keeping all your files in one place helps make backup a snap into backup media like CD, DVD or Magnetic Tape.
    3. Keep files separate from programs. By separating document files and program files you reduce the risk of accidentally deleting your documents when you install or upgrade programs.
  2. Adopt consistent methods for file and folder naming: Every company has their own naming convention. If your company haven’t one develop a naming scheme for the kinds of files you create most often and then stick to it. Do not use spaces in file names, keep file names under 27 characters, and use all lower case. So a file named should be “square_pharma” rather than “Square Pharmaceuticals Limited”. Oracle developer may be wanted to put all UPPER CASE and java programmer may want to do it with Camel Case. But I recommend you that, if you break any of these rules, be consistent about it.
  3. Keep names short: Even though Windows allows you to use long file names, it does not necessarily mean you should. Long file names are harder to read.
    1. Use abbreviations. Keep file names short by using common abbreviations, such as “MTNG” for meeting or “ACCNTNG” for accounting. This makes the file names more descriptive and you can more easily find files through Search if it’s necessary. I like to trim all vowels except first one for abbreviations. If possible create your own abbreviations style. But you must keep log and explanation written into a text file into root directory. Named that text file – “abbreviations.txt” or “readme.txt”. Please note, if you consistent with one rule you don’t need to put the text file.
    2. Let your folder structure do some of the naming: For example, rather than create a file called “great_bangladeshi_novel_chapter_one_first_effort.doc”, you can build a structure like:

      creative_writtings >> great_bangladeshi_novel >> draft01_u20091110_dr3 >> ch1 >> <then your file name>.doc

      creative_writtings/great_bangladeshi_novel/draft01_u20091110_dr3/ch1

  4. Nest folders within folders: Create other folders within these main folders as need arises. For instance, a folder called “invoices” might contain folders called “2004”, “2005” and “2006”. A folder named for a client might include the folders “customer_data” and “correspondence”. The goal is to have every file in a folder rather than having a bunch of orphan files listed.
  5. Organize files by dates: Use a date in the document name. Such as dv20081215, this would mean December 15, 2008. This puts all the DV sent at that specific date together and sorted by date.
  6. Be specific: Give files logical, specific names and include dates in folder names if possible. The goal when naming folder is to be able to tell what the file is about without having to open it and look. So if the document is a letter to a customer reminding him that payment is overdue, call it something like “overdue20081206” rather than something like “letter”. How will you know who the letter is to without opening it?
  7. Don’t save unnecessary files: Be selective about the files you keep. You probably don’t need to keep them all. With e-mail, for example, you rarely need to keep everything you receive.
  8. Keep individual folder for a project: Keep your entire document related a project into a folder. So, you can take back up for a project and burn CD.
    1. Separate ongoing and completed work. To keep the Documents folder from becoming too unwieldy, use it only for files you’re actively working on. As a result, you can reduce the number of files you need to search through and the amount of data you need to back up. Every month or so, move the files you’re no longer working on to a different folder or location, such as a folder on your desktop, a special Archive folder, flash drive, external hard drive, or even on a CD.
    2. Use common names. To make it easier to search for documents, name your files and folders with easily found names, such as model numbers, project names, or the project lead in the title. Suppose every project should have proposal. So, named this file as “proposal.doc” something like this. Every project need images file so create a folder named “images” into your project folder. So, that every image is related on that project can be stored into that folder.
  9. Use shortcuts and shortcut links instead of multiple copies: If you need to get to the same file from multiple locations, don’t create copies of the file. Create shortcuts to it instead. To create a shortcut, right-click on the file and click Create Shortcut. You can drop and drag the shortcut to other locations. Moreover you may need to organize your folder such way like current working folders, folder of MD sir, folder of software department etc. Those folders may be categorized by different way. So you can create shortcut of those folders and organize several way.
  10. Cull your files regularly: Sometimes what’s old is obvious as in the example of the folder named “Invoices” above. If it’s not, keep your folders uncluttered by clearing out the old files. Do NOT delete business related files unless you are absolutely certain that you will never need the file again. Instead, in your main collection of folders in your data storing drive or root folder, create a folder called “Old” or “Inactive” and move old files into it when you come across them.
  11. Back up your files regularly. Whether you’re copying your files onto another drive or onto tape, it’s important to set up and follow a regular back up regimen.
  12. Put Reference on the desktop: Put a folder named “important_shortcut” on the desktop. Put your entire folders or files shortcut icon into that folder. So, you can save several clicks of the mouse to get where you want to be sooner.

Proposed convention for a well organized file or folder name:

The proposed file naming convention defines a readable, delimited, long filename format. The delimiting character is an underscore or hyphen.  In all cases where an alphabetical character is called for, the character must be lower case. OS may be treat upper and lower case letters the same or not.  The required contents of the filename will be as follows, in order: “File Name,[ Version Information, Create Date with Time, Last Updated Date with Time]” Additional information may be added as required by the user.  The working group suggests that the additional information be in the following order: “Optional 1, Optional 2, and so on”. Additional information will add before optional information. If additional information exists there must be present optional information.  The extension will always follow.

So the template for the file name is as follows –
[File Name]__[Additional Information]__[Optional Information].[Extension]

Here point to be noted that, delimiter is double underscore of each section. So, you can’t use double underscore into a section. You can use single underscore or single hyphen to delimit each word. Double hyphen is reserved for system purpose or automatically generated file name. And we discourage you to use single hyphen too.

File Name & Additional Information:

File Name will discuss later. Additional information is totally determined by user. And we discourage to use additional information because you have full right to make your own style file name.

Optional Information:

Optional information is consisting with “Create Date with Time and Last Updated Date with Time, Version Information”. For put create date you need to put leading ‘c’ and for update date you need to put ‘u’. You can give any one information. And total information is optional. But it good practice to put this information into your file name. But if you put this information you must follow the order and delimit each section with single underscore.

Each version number will followed by ‘v’ and then version number without any delimiter. Example: v1, v35. Please don’t use 01 or 02 just count from 1 and so on. This is also suggested to use ‘dr’ for draft version followed by revise number. You also suggested putting application version information though it’s optional. I suggest to use application version cause, we will easily recognize by file name to what version I need to use to open this file. I faced the problem when I use Adobe Illustrator or Photoshop. Please follow this order to form version information “application version, version/draft number”. Example: av11v5-3, av9v6, dr9 etc. Here version 5.3 represent as 5 hyphen 3. So, you can user hyphen as delimiter.

Using a date in the file name always state the date ‘back to front’. Why? Because then when you look at your folder and sort it by file name, all the files will sort in the order of the dates. It’s a super-easy way of organizing your files by date. Use four digit years, two digit months, two digit days, two digit hour and two digit minute (we will recognized this minute with NN): YYYYMMDDHHNN or YYYYMMDD or YYYYMM or YYYY or YYYYtoYYYY or MMtoMM or mMMdDD or mMMdDDtomMMdDD or hrHHmnNN

Extension:

Most programs automatically add the correct “file extension”—a 3-letter addition to the end of the filename that identifies the type of file to your computer (.doc = MS Word document; .wpd = WordPerfect document). In general, do not alter the file extension. If your program didn’t provide it automatically provide by yourself with your own standard and according your file type, format and by which program you want to open this file.

Example: (Some examples of good file names with their explanation)

y2009_taxes_for_bob_smith__c20100121_u20100202.doc Here you can’t start file name with number so I use ‘y’ and it also including optional information (create date and last date of modify)
personal_budget_2008__v1.doc Here into optional information we put version information.
car_prices_2009.xls No optional information
investment_notes_from_june_2007_course__av2007dr15.doc It is creating by MS office 2007 and it’s a draft file that is revised 15 times till now.
js_daily_weight_200803__u20080401_v35.doc Here we last update this file at April 1 of 2008 and its revised 35 times when update.
to_do_list__av2007v3.doc The list of what to do today.

The conventions comprise the following 18 rules:

  1. The default file name is determined by that file contains.
  2. The name is formed by taking the full expanded name of the unit and replacing the separating dots with hyphens and using lowercase for all letters.
  3. File names must not contain spaces or any special characters such as “& + # \ / : * ? ” ‘ < > | ! .” or non-alphanumeric characters.
  4. Do not start the file name with a number.
  5. When in doubt, keep the file name as short and simple as possible, but meaningful. For example use hist_100a_readings.html not hist100ab*readings
  6. Be sure to include the extension after the filename – for example .htm, .php, .doc, .xls, .pdf, .ppt, .psd, .ai, .jpg
  7. Avoid using four digit extension name of a file format.
  8. Avoid unnecessary repetition and redundancy in file names and file paths. Example: Goodhttp://www.eg.edu/business/sell/staff/, Redundanthttp://www.eg.edu/business/sell/sellstaff/
  9. Use underscores or hyphens to delimit words, not spaces or capital letters.
  10. When including a number in a file name always give it as a two-digit number, i.e. 01-99, unless it is a year or another number with more than two digits.
  11. If using a date in the file name always state the date ‘back to front’, and use four digit years, two digit months, two digit days, two digit hour and two digit minute (we will recognized this minute with NN): YYYYMMDDHHNN or YYYYMMDD or YYYYMM or YYYY or YYYYtoYYYY or MMtoMM or mMMdDD or hrHHmnNN
  12. When including a personal name in a file name give the family name first followed by the initials i.e PR: Pronay Rozario
  13. Avoid using common words such as ‘draft’ or ‘letter’ at the start of file names, unless doing so will make it easier to retrieve the record.
  14. Order the elements in a file name in the most appropriate way to retrieve the record.
  15. The file names of records relating to recurring events should include the date and a description of the event, except where the inclusion of any of either of these elements would be incompatible with rule 8.
  16. The file names of correspondence should include the name of the correspondent, an indication of the subject, the date of the correspondence and whether it is incoming or outgoing correspondence, except where the inclusion of any of these elements would be incompatible with rule 8.
  17. The file name of an email attachment should include the name of the correspondent, an indication of the subject, the date of the correspondence, ‘attach’, and an indication of the number of attachments sent with the covering email, except where the inclusion of any of these elements would be incompatible with rule 8.
  18. The version number of a record should be indicated in its file name by the inclusion of ‘v’ followed by the version number and, where applicable, draft use ‘d’ followed by the version number. Also use application version (av) with their number by which the file created, except where the inclusion of any of these elements would be incompatible with rule 8.

Finally…

Everyone should have their own policy. But you must think about how can your public accessible file is more accessible in easy way, isn’t it?

For your information, I forgot my good hand writings. Really I missed those style…

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.
