Getting Your Deleted Files Back

Sometimes it happens; either you accidentally delete a file, or some type of system crash deletes them for you.  Either way, the good news is that your files aren't really deleted at all.  What happens to deleted files is that they are moved to an unused part of your hard drive where they stay in perfect condition until that part of the hard drive is needed for new data.  At that point, the new information overwrites the 'deleted' files.

In reality, files are not deleted, they are overwritten.  Provided your files have not been overwritten, there is a free program called Recuva which does a great job in 'undeleting' files so you can use them again.

Larger files may be recovered in parts, or pieces, but you just have to paste them together to get your file in its original form.

If not now, then sometime...Recuva will come to the rescue.

Memorial Day Tribute

On this Memorial Day, V6 Math is looking back at the times and events that created who and what we are today.

Garapan, 1920's & 30's

The War Starts with Massive Bombing of Saipan

What's left of Garapan

Life is Hard for Everyone: Local Population Taken to Camp Susupe

The War Finally Ends with Japanese Surrender:

Life Begins Anew: Opening of Mt. Carmel Church

That Was Then, This is Now:

You're never too young, too old, or too cool, to take a moment and appreciate the sacrifices others have made.  We are what we are and we have what we have because of the people in these pictures and the many, many more just like them.

If your grandparents or great-grandparents are still alive, take some time to appreciate them for their sacrifices and hardships as well.  You'll be a better person for it.

Long Weekend Break: Whatcha Gonna Do?

Have you looked outside your window?  The weather is beautiful this long Memorial Day weekend, so turn off the T.V., shut down the computer, close the book (as if), and get outside and do something.

Once again, V6 Math has provided some suggestions for your weekend activities.

Go for a Bike Ride

 

Play Baseball

Go to the Beach

Whatever you do, get outside and have some fun this weekend.

The Worst Show on T.V.?

I like Nikelodeon just as much as the next guy, but you gotta draw the line somewhere. I have found that line, and it is most definitely, Power Rangers Samurai. 

 

Did some 5 year old win a contest to write, direct, and star in their own show?  If so, it must be Power Rangers Samurai.  My apologies to those who can't wait until 10:00 on Saturday mornings so they can cheer for their favorite color crayola crayon, but I'd rather watch this:

Or this:

By the way, what ever happened to Teen Titans?  Now there's some super heroes for you.

Speed Up Your Windows 7

Who doesn't want more speed, especially with netbooks like your Dells.  Here's a great, simple, and Microsoft approved method of achieving your need for speed. 

You will need a flash drive or card with at least 1gb of free space on it.  The computer will use your flash drive to increase its RAM, the space used for memory.

What to do:

If you do not see the Autoplay dialog box, right-click the device or drive, and then click Open Autoplay. If the device isn’t plugged in, hold down Shift and plug in the device. You can also hold down Shift while inserting a disc to see the list of options.

If you do this, (insert and use a flash drive or card) every time you start your computer, you should notice a definite increase in processing speed.


Notes: 
With autoplay on, you just have to have the flash drive inserted, readyboost will run automatically after you set it up the first time.

Increased processing times does not mean faster internet speeds. Your internet speed is determined by your connection type, (dial up or broadband), how many people are sharing the connection, wired or wireless connection, and if wireless, how far from the router you are.  

Ready boost will make everything else faster, though.  Opening and closing programs and documents, saving, opening files of any type, and anything else you do off line.

Upgrade Your Windows 7

There are a number of free programs you can install to improve your operating system, Windows 7 Starter Edition. While Windows 7 looks and works great, the starter edition leaves out a lot and is very limiting.

One free upgrade you can make is to install Start Menu 7.  This program changes the look and function of your start menu, one of the areas that I personally think is plain bad in the starter edition.

This program makes it much easier to find files and folders, and change any settings in the control panel and elsewhere.  Here's a screenshot of the program when you click on start:

As you can see, most everything is available in one click. You no longer have to click and double click through links and folders to find what you want.  Give it a try. As always, you can delete the program if you don't like it and your system will appear exactly as before.

Final Exam Review Parts I-IV

Science Alert: Human Body Maps

 Yes, I know it's the end of the school year and you probably won't need this resource now. But, you probably will want to use this and other sites I've posted next school year. So, bookmark this site for later use. You'll be glad you did.

Anyway, Human Body Maps, by Healthline is a great site for exploring the human body. You can check out the nervous, respiratory, reproductive and other body systems. Views are available for both male and female bodies. Also, there are views of all the organs, heart, liver, kidneys, etc. Everything can been seen from any angle as well.

Advanced System Care Free 4

A new version of Advanced System Care is out and it is worth downloading.  However, after downloading and installing, it is best to make the following changes:

1. Click on Toolbox, Optimize, Startup Manager
2. Uncheck any box that has to do with Advanced System Care, Quick Care, or IOBIT

Why? You'll want to run this program every week or two in order to clean up your system, but you don't want it running automatically when you start your computer. In the last post I mentioned your limited resources. You don't need ACS everyday and the more start up programs you have, the longer it takes to start your computer.

So download, install, make the quick changes, and use the program every 10 days or so. Very worth it.

iTunes Not the Best for Your Laptop

Are you using iTunes as the music player/organizer on your laptop? While iTunes is good at what it does, it's just not the right player for your laptop.

Here's what you always need to keep in mind when it comes to your laptops: (actually they are netbooks, meaning smaller, less powerful laptops) You have limited processing, storage, and memory on your Dells.  iTunes is a program which commands a lot of resources from your computer, especially if it opens when you start up your computer. iTunes is a resource hog, what you need is a resource ant. 

One music player/organizer which is not a resource hog is Jaangle. It is a very small file compared to iTunes and is not always accessing on-line resources like the iTunes store, which slows your browsing.

You can download Jaangle here. Since it is a small file, you can install and try it out in almost no time.

You no like? No problem. Uninstall, then delete the installer.  If you do try Jaangle, let me know how you like it, it's always good to hear the opinions of people who have actually tried a program.

Feeling Sleepy in Class?

How much sleep do you need, and are you getting enough of it?  The latest science says this:

Teenagers

Before puberty, sleep is often fine, no problems. As you enter puberty though, all heck breaks loose!

In your teenage years, your body clock changes so that very often you are more alert during the end of the day. Why? Science isn’t really sure, but teenagers are usually more tired in the morning than they are in the afternoon.  Does this sound like you?

To make things worse, if you are alert and awake until late at night, you’ll get less sleep and be even more tired in the morning. As a teen, you need around 9-10 hours of sleep a night. 

So if you get up at 6:00 am, you’d have to go to bed by 8:00 pm to get your needed sleep.  Who goes to bed at 8:00? No teenager I know.  Do you?

Now, the big question:  Would you prefer school to start at 9:00 and get out at 4:30, or do you like this early schedule better?  Answer the poll question on the right sidebar.

How to Copy, Cut, and Paste for Beginners

It's such a simple operation, you'd think everyone already knows how to copy, cut, and paste.  But since I've been asked a few times how to do this, here is a quick beginners guide.

First, What's the difference between copy/paste and cut/paste?
When you copy/paste, whatever you are copying stays where it is. After you paste it, you now have that text or that picture in two places: Where you copied from and where you copied to.

When you cut/paste, the part you are cutting is removed from its place and moved to the place you are pasting it to. You don't have two copies of it like you do with copy/paste.

So, how do you cut or copy and paste?
First, select the item you want to copy or cut:

• If it's a file in a folder that you want to copy (to duplicate) or cut (to move) into another folder, click on the file to select it. To select multiple files at once, hold down the Control (CTRL) key (on Windows)  while clicking the other files.
• For images, right-click on the image, then click on "Copy" or "Copy Image" depending on the application.
• If you want to copy some text, highlight it by clicking just before the first letter you want to copy, hold down the mouse button while dragging your mouse to the right, and then releasing after you have selected your text.

Copying/Cutting and Pasting: The Point-and-Click Method

Next, in many applications, you'll see at the top of the application window, "Edit" right next to "File". Click Edit to reveal the drop down menu and select Copy or Cut, depending on what you want to do and if cutting is an option.

Okay, now that we've selected the item and copied/cut it into memory, we can paste it somewhere else. In your new document or folder, go back to Edit and select Paste. Alternately, if you don't have that Edit menu (e.g., in Windows Explorer), right-click in the document or folder and select Paste.

A Faster Method: Keyboard Shortcuts

Copying, cutting and pasting with your mouse is pretty straightforward, but using keyboard shortcuts can save you a lot of time.

Select your items to copy or cut as above. To select all items on a page or folder, you can use the CTRL+A or Command + A shortcut: hold down the CTRL button (on Windows) or Command key (on Mac) then hit the A key.

Then hit these keys together to copy, cut, and paste them:

Windows: Hold down the CTRL key then click

• C to copy
  or
• X to cut
• V to paste

That's all there is to it. Practice a few times, and you'll be able to do it without even thinking.

Are You A Stargazer?

Do you ever look at the night sky and wonder if those reddish blue lights are stars or planets? Ever want to know what Taurus or Leo or Pisces looks like?  There's a great free program called Stellarium which shows you planets, stars, constellations, asteroids, and everything else in the sky at that exact moment.

In fact, this week just before sunrise, there are four planets grouped very close together looking toward the east.  I got up early Friday to see this, and was amazed at how bright Jupiter was and how red Mars is.

If you do download the program, the first thing you do is go to location on the left side and type in Saipan. 

After that, the sky you see on Stellarium will be the exact sky you see when you look into the real sky; any night, any day, the program and the sky will match.

It's not a program you'll use everyday, but sometimes you see something at night and might wonder what it is. Now you can load up Stellarium and know exactly what that object is.

Finally, there are quite a few events coming to the sky in the next few months which are very rare, once-in-a-life kind of events. Planet alignments, eclipses, asteroids coming close to earth and others. With Stellarium, you'll know what's going on.

Do You Have Triskaidekaphobia?

You might have Triskaidekaphobia and not even know it.  If you think you might have it, you should really have it checked out.  It might cause you to miss school today.

Send me an email, and tell me what Triskaidekaphobia is. If you're one of the first three, you got yourself a free hour of computer time.

For those of you who have free computer time, you've got just two weeks to use them. So don't forget to tell me "No work now, Mr. Ferrari, I'm going to use my computer.

Weekend Tips: Online Storage & More

Maybe you know someone whose computer has crashed already; possibly that person is you.  Nothing is worse that having your computer crash.  Even though there are other, harder ways to save your data, most computer shops will fix your computer by wiping your hard drive clean and starting over.

The result: You lose all of your data. Pictures, programs, documents, grandma's secret pig's feet recipe. Gone. All of it.

Here's the thing: You never know when it is going to happen. It's happened to me, it's happened to everyone who's used a computer for a while.  So, be smart, be free, and do it for free.

There are many places where you can store between 2 and 50 Gigabytes of data for free. If you have anything on your computer you don't want to lose, create an account, upload all your stuff, and never worry about a computer crash again.

An added bonus is that you can create public and private folders. If you have some pictures you want to share, upload them to your public folder and give people the web address. They can get the photos, documents or whatever themselves.  No more flash drives, dragging things around. Clean and easy.

Here are some links to online storage sites:  ADrive, OpenDrive, Flickr,   and finally, don't forget about Gmail. If you have an account, you have 7 gigabytes of storage. You can add anything as an attachment and upload it. There is no public folder with Gmail, though.

 Don't learn your lesson the hard way. Get an account, upload the things you don't want to lose, and sleep well at night.

Quick Tip #2:

If you're leaving your computer for a few minutes and don't want anyone messing with it, you can quickly and easily lock the keyboard by pressing the Windows key and the L key. Win + L. Just takes a second, and your computer is secured.

Test Prep: Stem & Leaf Samples

Try working these problems before checking the answer. It will go fast and you'll be better prepared for tomorrow.

First, draw the stem and leaf for the following data:  30, 43, 25, 18, 8, 14, 37
Before plotting the data on the stem and leaf, arrange the data from least to greatest.

After putting the data in the stem and leaf, find the mean of the data.

Then find the median.

Finally, find the mode.

Stem & Leaf Sample 2: 
For this example, you only have to place the data in the stem & leaf.  Here's the data:
117, 109, 123, 85, 102, 127, 215, 136

After doing the problems, the answers can be found here.

Don't forget to check the previous post for sample mean, median, and mode questions.


Good Luck, see you tomorrow.

P.S. I'm still working on the Super Teaser, give it a day or two at most.

Test Prep: Mean, Median & Mode

Here's a quick review for tomorrow's test. Try to work the problems before checking the answer.

Mean:  First, Sum all of the data, then divide by the number of items in your data.  For example: You are asked to find the mean of 6,10,5,7,6,8,.  Try working the problem now. Add up the numbers and then divide by 6, the number of data points.  Go ahead, work it, I'll wait.

Here is the answer:

     Sum = 42, divided by 6 = mean of 7     Press and highlight the blank area before the sentence to view answer.

Median:  When finding the median, you must first place the numbers in order from least to greatest or greatest to least. Using the same numbers above, they are rewritten 5, 6, 6, 7, 8, 10. The median is the number in the middle. If you have an even number of data items, like we do here, add the two middle numbers and divide by 2. Go ahead, find the median..

   6 + 7 = 13 /2 = 6.5  Once again, highlight the area before this sentence for the answer:  Did you get it correct?

Mode: The mode is simply the number that appears most often, the most common number. For our numbers, 5, 6, 6, 7, 8, 10, the mode is, what? Did you get  6  for the mode?  Hope so.

Check back a little later tonight for Stem & Leaf examples, gotta go walk the dog now.
