How to draw a flowchart on Microsoft Word 2007

Flowcharts are a very good way to get a new idea explained in a presentation. Microsoft Word 2007 has some great new tools for creating a visual appealing flowchart which can be used from Excel, Word or PowerPoint.  Here we will take a look at creating a simple flowchart in Word 2007.   

For the sake of this article I am going to start at the top of the document on the right side under the title.  Then click Insert then Shapes on the Ribbon to select a shape from the Flowchart section.  You can can then draw an outline for the size of this object on the document.  You then will see how it will look right away.   

Basic Flowchart Symbols

-- Basic flowchart Symbols --

Flowchart can help us to plan, depict and communicate with ourselves and others the tasks on hand. The flowchart symbols are dynamic and their meanings continue to grow and change depending on who uses them. Please find out more about the complete Flowchart Symbol set in wiki, http://en.wikipedia.org/wiki/Flowchart. The following represents the most commonly used symbols are their generally accepted meanings:

The Process Symbol represents any process, function, or action and is the most frequently used symbol in flowchart.


The Document Symbol is used to represent any type of hard copy input or output (i.e. reports).


The Offpage Connector Symbols are used to indicate the flowchart continues on another page. Often, the page number is placed in the shape for easy reference.


The Input/Output Symbol represents data that is available for input or resulting from processing (i.e. customer database records).


The Comment Symbols are used when additional explanation or comment is required. This symbol is usually connected to the symbol it is explaining by a dash line.


The Decision Symbol is a junction where a decision must be made. A single entry may have any number of alternative solutions, but only one can be chosen.


The Connector Symbol represents the exit to, or entry from, another part of the same flowchart. It is usually used to break a flow line that will be continued elsewhere. It's a good idea to reference page numbers for easy location of connectors.

How 3D TV Works - Without Glasses

3D TV autostereoscopic

 

We are used to see the common ways in which 3D television works when paired with special glasses. However, this stereoscopic method leads to two distinctive problems:

1) The glasses are really cumbersome and expensive, and you don’t want to accidentally sit on one or lose it. Plus, it takes away the simplicity of television as it stands today, where you simply hit the remote and start watching.
2) Also, without the glasses, any 3D content is completely unusable. The screen has been calibrated to work with 3D content and so dropping the glasses would end up displaying garbled images.
 
Recognising these limitations, several companies like LG and Panasonic are working on making autostereoscopic 3D TVs, where the user is free of any special accessories.
 
But before going on, here’s a recap of the one basic preface needed in understanding 3D television: understanding how our eyes work. For the sake of this example, look at your computer mouse (or if you’re on a laptop, any other three-dimensional object nearby). In a nutshell, your left eye and your right eye are two separate lenses, registering two different angles of the mouse. The two eyes send the two differently-angled images of the mouse to your brain. The brain then acts as the ‘image processor’, putting the two pictures together to come up with one three-dimensional picture in your mind. It’s basically the same principle by which the new FujiFilm FinePix 3D camera works. 
 
Autostereoscopic 3D television sets work on a similar principle, with two main technologies that rely on it: lenticular lenses and parallax barrier.
 
Lenticular lenses
The less popular of the two autostereoscopic models involves the use of lenticules, which are tiny cylindrical plastic lenses. These lenticules are pasted in an array on a transparent sheet, which is then stuck on the display surface of the LCD screen. So when the viewer sees an image, it is magnified by the cylindrical lens.
 
Lenticular lens 3D TV
 
To see how this works, roll up a newspaper or magazine (we recommend Digit!) into a cylindrical shape and hold it up in front of you. Now, with your other hand, cover your left eye. Notice the text and pictures that your right eye can see. Then uncover your left eye and use your hand to obstruct your right eye. Naturally, given the two varying angles, you will see a bit more of text and pictures on the extreme left side when you look with your left eye, and vice versa. By combining these two images, our brain can perceive depth. 
 
Similarly, when you are looking at the cylindrical image that the TV is now showing you, your left and right eye see two different 2D images, which the brain combines to form one 3D image.
 
However, lenticular lenses technology is heavily dependant on where you are sitting. It requires a very specific ‘sweet spot’ for getting the 3D effect, and straying even a bit to either side will make the TV’s images seem distorted. Depending on the number of lenticules and the refresh rate of the screen, there can be multiple ‘sweet spots’.
 
Parallax Barrier
The other major method to enable autostereoscopic output is called the parallax barrier. This is being actively pursued by companies such as Sharp and LG, since it is one of the most consumer-friendly technologies and the only one of the lot which allows for regular 2D viewing.
 
The parallax barrier is a fine grating of liquid crystal placed in front of the screen, with slits in it that correspond to certain columns of pixels of the TFT screen. These positions are carved so as to transmit alternating images to each eye of the viewer, who is again sitting in an optimal ‘sweet spot’. When a slight voltage is applied to the parallax barrier, its slits direct light from each image slightly differently to the left and right eye; again creating an illusion of depth and thus a 3D image in the brain.
 
 
The best part about this, though, is that the parallax barrier can be switched on and off with ease (one button on the remote is all it would take, according to Sharp), allowing the TV to be used for 2D or 3D viewing. So on a computer monitor, you could play video games in full 3D glory and then easily switch to 2D mode for your work requirements.
 
While the wide range of content it offers is heartening, again, the need to sit in the precise ‘sweet spots’ hampers the usage of this technology.
 
Still, there are quite a few companies finally looking to make 3D TVs a reality. In the upcoming third part of this series, we will take a look at some of the brands and products that promise to bring next-gen content to your living room.

Week 02 - Freed by Google, no more Window's Office

I have been looking for a copy of office suite can work with Vista x64, as the number of free trials on the Michelle's new Vista x64 notebook quickly counting down single digit. After a dozen different installations and uninstallations, just as I thought that my only option is to pay the heavily discounted student license seat for $60. Google Doc. came to save me. Now I can import/export Microsoft Words, Excels, and Powerpoint files from/to Google Doc freely and truthfully.

(The following is not a Google advertising, but my own observation.)
We can now:
work on all my documents anywhere with a browser connected with Internet;
collaborate with others without sending the files back and forth, read only or writable;
find (google search) the file from the big pile of files of inconsistent or no filing and naming habit.

Need more reason to NOT pay Microsoft and continue to suffer?
Log in Google Doc, http://docs.google.com/ and test it out with word, excel, and powerpoint files.
For how to import/export Office files, see http://docs.google.com/support/bin/answer.py?hl=en&answer=50092

My PC is canned regularly, why is it getting slower?

Someone asked me about why his PC is getting slower, even the PC is scanned daily.

Several reasons may cause the computer to slow down:
  1. Too many software programs have been installed as starting at boot.
  2. Hard disk drive is short on available disk space.
  3. Data Corruption.
  4. Computer is overheating.
  5. Corrupt OS.
  6. Bad Hardware.
The most common cause is #1. too many software programs have been installed as starting at boot. Once the program is installed as starting at boot, that program is having a piece of the precious resource, regardless of whether you use it or not. The evidence can be found in the increasing number of running tasks in Windows Task Manager (by ctrl-alt-delete). Over time, more and more programs were installed and started at boot, hence the PC gets slower and slower.

It is really difficult to find out which process (name) is what program is almost impossible. The easy way to regain those lost resources, i.e. to speed up your PC, is to NOT starting all applications at boot, or clean boot. In the mean time, these software are remian installed, but not started. They are evoked only when you need to.

Google Voice

Google Voice, formerly GrandCentral, is a seriously heavyweight product. When it relaunched in March, just a couple of months ago, we gave Google Voice a glowing review.
Once you’ve jumped in head first to the product it will straighten out your phone life forever. You’ll never have to worry about figuring out which phone numbers to give to different people. Give them one number - your Google Voice number - and then use rules to determine where your calls go based on who’s calling and what you are doing.... read on

Free Antivirus Altenative

We have discussed the free anti-virus alternative instead of paying expensive Norton subscription.

My answer is to use the free anti-virus, and my favorite anti-virus are:
AVG, and MalWareBytes. Both are excellent security products, The AVG came with a suite of different defensive weapons, such as the (IE and Firefox) browser safe search plug-in. The safe search screen all search results, and warn you on those pages that may contain any potential harmful script.

You may also try Avira or Avast . Both are decent and light weight cause less of a performance hit.

All anti-virus software can not keep the virus, worms, and Trojans completely away. Surf responsively, and make sure your Windows are up to date at all time, especially those security updates. Keep your Windows Security Center armed at all time, i.e. turn Control Panel -> Firewall, Automatic Updates, Virus Protection, all On.

Assignment 1 - Build a PC on paper



LABAR Project 1

This assignment is to be done during your one hour lab by arrangement (LABAR). This assignment requires you to build a virtual computer from the motherboard up.  You can go to several computer stores that have individual components and price it out or you can complete this all online and submit your finished “masterpiece” in webct.dvc.edu, assignments link.  This project will build as the COMSC100 course discusses each of these topics.






1.) What do you want your computer to be able to do?  This is the first question you have to ask yourself before you can pick the right one.  Once you know this, and you can do some research on what’s available before deciding, then go to step 2
2.) Research motherboards
a.     There are different manufacturers, types, and styles. Find the one that best fits your answer to step 1.  Price is no object.  Remember, this is a virtual machine you are building.
b.    List the features that will be important to you and why you chose this motherboard
c.     Take a copy of the motherboard you have chosen and place in Microsoft Word or Paint.  Paint will allow you to resize it, crop (cut parts out/modify) or group components together.  You might want to use a table in MS Word or the alignment and crop tools
3.) List the components you will need i.e. case, memory, hard drive, processor, graphics card, sound card, printer card, there may be more as your project continues. List the purpose of each component.  You can list the purpose of each component as the project goes along if that works better for you. This will give you a guide for the rest of the project.
4.) Research cases
a.     Find the case that is right for the motherboard you chose in step 2.
b.    Take a copy of the case you have chosen and place in Microsoft Word or Paint.  Paint will allow you to resize it, crop (cut parts out/modify) or group components together.  You might want to use a table in MS Word or the alignment and crop tools
c.     List the features that will be important to you and why you chose this case
5.) Research microprocessors
a.     Find the processor that is right for the motherboard you chose in step 2.
b.    Take a copy of the processor you have chosen and place in Microsoft Word or Paint.  Paint will allow you to resize it, crop (cut parts out/modify) or group components together.  You might want to use a table in MS Word or the alignment and crop tools
c.     List the features that will be important to you and why you chose this processor
6.) Continue researching the components that you will need to build your computer.
a.     Find each component that is right for the motherboard you chose in step 2.
b.    Take a copy of each component you have chosen and place in Microsoft Word or Paint.  Paint will allow you to resize it, crop (cut parts out/modify) or group components together.  You might want to use a table in MS Word or the alignment and crop tools
c.     List the features that will be important to you and why you chose each component until you have a complete system
7.) Research and add the peripherals you will need.
a.     Find each peripheral that is right for your needs
b.    Take a copy of each peripheral you have chosen and place in Microsoft Word or Paint.  Paint will allow you to resize it, crop (cut parts out/modify) or group components together.  You might want to use a table in MS Word or the alignment and crop tools
c.     List the features that will be important to you and why you chose each component until you have a complete system
8.) Place your components in a professional, attractive presentation in MS Word or MS Powerpoint.  Be sure to include a description of each component, its purpose, and why it was your choice. 
9.) Research the operating system and other software you will need.  Be sure to list the reasons for your decisions.
10.)    Go online or go to one of the many local computer stores, i.e. PC Systems on Willow Pass Rd., Fry’s electronics, R Computers, etc. and price out your system.  State if you will purchase your dream machine now, in the future, or never; at least not as far as you know J.
11.)    Submit your finished project according to your instructor’s instructions.
We hope you enjoy this project and learn a lot from it.  The rest of your LABAR projects will be your programming assignments in HTML and JavaScript.
