Computer Class Notes for 3-19-2019

We all use CCleaner to clean the junk out of our hard drives and to clean the registry. I have been reading articles about cleaning the registry and the general consensus seems to be that it has no effect on the speed of the computer. I read that when Windows boots the entire registry is loaded into RAM which negates the need to defrag it or even clean it up. I have never had a problem using the registry cleaner in CCleaner, but some have indicated issues with windows after cleaning it. I have seen performance improvement when the cleaning finds hundreds of issues, but that is when it has not been cleaned in years of use.

There is a shortcut to cleaning the junk--right-click on the recycle bin and choose Run CCleaner. That does the cleaning in the background and you will notice a spinning CCleaner icon in the lower right of the taskbar.

In looking into the possibility that a too good to be true website selling cheap laptops we came across which reports as to the validity of a website. When we entered the URL for the questionable site it reported that this was not a safe site.

RANDOM.ORG offers true random numbers to anyone on the Internet. The randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs. People use RANDOM.ORG for holding drawings, lotteries and sweepstakes, to drive online games, for scientific applications and for art and music.

Keep A Portable Ubuntu Installation With You Wherever You Go
Having a PC in your pocket is a massive advantage. But how can it be done easily? The answer, of course, is via a USB stick. With a version of Ubuntu installed on your USB stick, you’ll have access to the web, to your favorite files and folders… all without the pain of lagging a laptop around.

Paint Dot Net
Originally intended as a free replacement for the Microsoft Paint software that comes with Windows, it has grown into a powerful yet simple image and photo editor tool. It has been compared to other digital photo editing software packages such as Adobe® Photoshop®, Corel® Paint Shop Pro®, Microsoft Photo Editor, and The GIMP.

Program Switcher
Switch one program with another! For example, anytime you perform any action that would normally start Microsoft Paint, you can switch this program with Paint.NET, so that it starts instead! It is incredibly useful after major Windows 10 updates which reset file associations back to defaults; with Program Switcher you can always force your preferred program to run instead of Microsoft’s default program!

SurveyMonkey is an online survey development cloud-based software as a service company, founded in 1999 by Ryan Finley. SurveyMonkey provides free, customizable surveys, as well as a suite of paid back-end programs that include data analysis, sample selection, bias elimination, and data representation tools.Wikipedia

Write Caching, if enabled, sends disk write-requests to computer memory (RAM) instead of directly to the much slower hard disk drive (HDD). This frees up applications from having to wait for the drive to finish its work before moving on to other tasks. This option is why we need to safely remove our USB devices before unplugging them.

How to use the new Snip & Sketch
Beginning with version 1809, Windows 10 offers an expanded range of screen capture options. You can save the full screen, the active window, or a rectangular selection to a file or to the Clipboard for reuse in another app. Here's how the new tools work.

Notepad Online
Perfect for quick, secure note taking. It was designed for simplicity, security, and speed. It loads immediately into a blank notepad and anything you type is instantly encrypted and saved. — You can add a password on any note and share it securely.

The 10 Minute Mail lets you create a temporary email address. Why? You just want to download that delicious recipe and they want your email address. You know what they want it for--to send you junk mail. Instead of using your real one, create a temporary one and use it. They may want to have you confirm your email and this lets you read any emails sent to it. If you need 10 more minutes, you can add it--again and again.

Easy Screen Capture
With 1803 we were given an easy way to capture a screen by pressing Win+Shift+S. Draw a box around what you want to capture and release the mouse. Your image is in the clipboard.

With 1809 the clipboard is no longer a one time clip. Win+V will open the clipboard where you can view every item that has been copied since the last reboot or since you cleared the clipboard.
