Webcam USB PHY 2.0 Driver Error

What USB PHY 2.0 driver?

An apparently missing USB PHY 2.0 driver error is known to come up with a type of inexpensive generic web camera. When this error presents itself the webcam is inoperable. Furthermore Windows Update cannot provide a driver. The error is displayed under Device Manager under Other Devices and associated with Hardware ID USB\VID_1224&PID_2A25&REV_0100. Aside from that though there is not much to go on even on the internet.

Given the description of the error one might be led to believe that one needs to find a driver USB PHY 2.0 driver from somewhere and install it. That is probably not the case. Going down that route is likely going to be a waste of time if the simple solution works. Because there is a simple fix to this problem. The quick fix is to make sure to install the webcam in a USB 3.0 port and not a USB 2.0 port.

How to Improve Virtual Machine Performance

In situations where the VM is installed on the same hard drive as the host's operating system the performance bottleneck is often the system's ability to read and write from the hard drive while running the VM and host operating system at the same time.

To improve VM performance try changing the location of the VM installation to a separate physical drive from the one on which the operating system of the host is installed.

32-bit or 64-bit CPU

How to Determine Whether Computer is Using a 32-bit or 64-bit Processor

To find out if your computer is using a 32-bit or 64-bit Intel processor look up the model specifications at http://ark.intel.com/

If it is a 64-bit processor the following should be seen in the table  "Intel® 64: yes".

One can also run CPU-Z to find out. Under the CPU menu Instructions field you should see EM64T listed.


AMD  64-bit processors will show AMD64.

In Windows, once can also get a description of the processor by typing into a command prompt the following: wmic cpu get description

The instructions here are on how to find out if you are using a 32-bit or 64-bit CPU not how to find out if you are using a 32-bit or 64-bit version Windows operating system.  Some of the instructions found on other sites although claiming to address the former seem to be answering the latter question and not the former.

Working with HTMLCollections in JavaScript and jQuery

To manipulate HTMLCollections successfully, one must be able to correctly identify and select the kind of object that one is working with. Depending on the command used on an HTMLCollection a DOM element or jQuery object may be returned.  The kind of commands that can be used on such returned elements or objects depends on the nature of that element or object. jQuery methods can only be used on jQuery objects not DOM elements.

Select and Create HTMLCollection

For example to select and create an HTMLCollection from all paragraph elements in an HTML document:

JavaScript 

document.getElementsByTagName("p")

jQuery

$('p')

Access HTMLCollection and Get Item as DOM Element

To return the first element (in the above case paragraph) in an HTMLCollection as a DOM element use one of the following:

JavaScript

document.getElementsByTagName("p")[0]
document.getElementsByTagName("p").item(0) 

jQuery

$('p')[0]
$('p').get(0)

Note the above jQuery commands return the first element as a DOM element.  DOM elements cannot be modified with jQuery methods. For jQuery methods to work they need to operate on jQuery objects. So something such as $('p')[0].text() will not return the expected result.  Use $('p')[0].textContent instead.

Retrieve Item from HTMLCollections as jQuery Object

To return the first element as a jQuery object use one of the following:

$('p').eq(0)
$('p:eq(0)')
 
Since it returns a jQuery object the command $('p').eq(0).text() should work.

Pangrams for Faster Typing

Typing Test Pangrams

 A pangram is a phrase or sentence that contains all 26 letters of the alphabet. 

"The quick brown fox jumps over the lazy dog" is probably the best known pangram.  It is commonly used as an example in typing lessons to get one used to touch typing. But there are other pangrams one could also practice typing out. Using a variety of pangrams may efficiently help increase muscle memory with varied letter combinations and patterns. Therefore typing pangrams is an effective way to improve touch typing speed.

Here are a few pangrams to use for typing practice:

Five jumping wizards hex bolty quick.
Pack my box with five dozen liquor jugs.
The jay, pig, fox, zebra and my wolves quack!
A wizard’s job is to vex chumps quickly in fog.  
Amazingly few discotheques provide jukeboxes. 
Watch “Jeopardy!”, Alex Trebek’s fun TV quiz game.
While making deep excavations we found quaint bronze jewelry.
A quart jar of oil mixed with zinc oxide makes a very bright paint.
The job requires extra pluck and zeal from every young wage earner.
The jukebox music puzzled a gentle visitor from a quaint valley town.
The public was amazed to view the quickness and dexterity of the juggler.

Pangram Typing Tips

Make sure you are in a comfortable position.

First learn them one at a time getting comfortable typing each one out over and over on its own then start adding and alternating the ones you have mastered in combination.

Practice typing for accuracy first then start typing with a view to accelerating speed.

Learn to tap the keys lightly and string common letter combinations together. 

Practice typing drills with these pangrams for a week or two and see your touch typing speed improve!
