Urban Dictionary

Urban Dictionary

This site is not necessarily for everyone, as it is describing slang, but I found it, because I heard a song on the radio talking about showing someone your grill and had no idea what it meant.

Meanings of grill:

buy propecia online usa align=”justify”>1.) Teeth
2.) A gold/diamond plate that is molded for your teeth. It is decorated with diamonds and/or gold. Usually worn by rappers, Nelly, Paul Wall, Mike Jones and many others.

I was highly confused, so I had to find somewhere to look it up and I found this site. I think this site is also handy for monitoring the slang coming out of your children’s mouths. My mom wouldn’t let us use slang around the house. We always had to speak perfect English. This is what comes of having a teacher for a mom. I am extremely grateful that she did, because It made me better able to communicate.

There are several ways to surf this site. The easiest way is to type in the word you want to define in the dictionary, like I did. Put in the term you want to define and click the search button.

Or, you can go through alphabetically, A-Z, and browse slang words by letter. Or you can click Random at the very end of the A to Z listing and get a random word. There are also random listings that change on the main page.

I wouldn’t want my children using a lot of this terminology, that is for sure. Another warning that I just noticed: some of the examples do have profanity in them, so I wouldn’t recommend showing this site to kids.

Focal Length and Magnification Factors

When people talk about lenses, they talk about focal length. This is basically a measurement that will help you determine how far your zoom can "reach" or how much of that great scenery your wide angle lens will encompass.

For those who wonder how it's figured out, it's the distance from the "optical center" of the lens to the point where it is focused when set to infinity. (No, we're not talking luxury cars here. Setting a lens' focus to "infinity" simply means to focus a lens at its furthest distance). Don't worry, you don't need to know or understand any of that to figure out how this works! šŸ™‚

Here's the practical application: the smaller the focal length of a lens, the more it can "see" and the more "stuff" you can get in the photo. Small focal length lenses are commonly referred to as "wide angle" lenses.

On the other hand, the higher the number, the less the lens is able to "see" and the closer your subject looks. These are usually referred to as "long" or "telephoto" lenses.

Back when 35mm cameras ruled the roost and digicams were only cute "toys," focal length made it easy to compare one lens to another. If it was a 28mm lens, it was a wide angle lens. If it was a 300mm, it was a telephoto lens. It was simple because the size of a 35mm negative was the same from camera to camera. A 50mm lens on one camera "picked up" the same scene as a 50mm lens on a different camera

Now that digicams are taking over, the game has changed. This is because of the size difference with the various image sensors out there.

You see, a smaller sensor doesn't "see" as much of the scene as a larger sensor does. In essence, it's cropping in, which is called the magnification factor. Since sensor sizes range all over the board, the image you get with a 28mm setting on one camera will probably look completely different on another.

Note: In the photos above, although the lens sees the exact same thing, the camera with the red sensor captures more of the scene than the camera with the blue sensor. Both were taken with a 28mm lens, but the results are very different.

Fortunately, a lot of manufactures are starting to give the 35mm equivalent ranges when they discuss their equipment. So, instead of saying a camera has a 7mm/28m lens, they give you the 35mm equivalent of 28mm/112mm.

So, if you see a camera that has 35mm equivalent focal lengths listed, here's a chart to help you decide if you have enough lens.

35mm Lens Chart:

12-20 – Ultra Wide Angle

24-35 – Wide Angle

40-80 – Normal lens

90-135 – Short Telephoto

150-250 – Medium Telephotos

buy propecia no prescription align=”justify”>300+ – Longer Telephotos

Okay, if you're shooting with a regular digicam, that's about all you need to know. However, if you have a digital SLR (you can take the lenses on and off), you'll want to read on.

Most digital SLRs do not have a full frame sensor. This means there is a magnification factor with any given lens. Normally, this is around 1.5, so we'll use that for our example. Check your owner's manual for the exact number.

Anyhow, here's what happens with this magnification factor. Let's say you have a 200mm lens. If your camera has a mag factor of 1.5x, that means you take the focal length of the lens (200) and multiply it by 1.5. In this case, your 200mm is now equivalent to a 300mm. Cool!

Now the bad news. If you like taking wide angle shots, this works against you. For example, that 24mm lens you liked so much on your 35mm camera now looks like a 36mm lens (gasp!) In order to get back to 24, you'd need to fork over lots of dead presidents for a 16mm lens! That pain you just felt was from your wallet.

So, if you're into long lenses, you'll probably like the magnification factor. If not, you may need to start stitching images together. Short of that, most manufacturers now have special "digital only" lenses that don't cost as much as the standard 35mm equipment (won't work on it properly either). They aren't necessarily cheap, but it may be worth looking into.

Oh, there are cameras that have a full frame CMOS sensor, so there is no magnification factor. Unfortunately, they sell for $7,000+ so it's probably cheaper to buy some new lenses. šŸ™‚

Geez, I talk too much! Happy shooting!

The fastest and easiest way I've found to do this is to right click on your desktop and select Properties. From the resulting window, click on the Display tab.

You can go ahead and scroll through the list of images that the Windows XP people kindly provided and you can also preview them in the top window.

Feel free to change the Position mode from Stretch (one big picture) to Tile (many little pictures) to Center (one small picture in the center of your desktop with a hand picked color filling in the background).

Now, if you want to use a picture that you have saved on your computer, simply click the Browse button and an Open window will appear. It will default to your My Documents/My Pictures folder, but you can browse through other folders via the Look in: box at the top.

Once you've found the picture you want, click on it and then click the Open button. This will take you back to the Display Properties window and you should see a preview of your brand new desktop. When you have things looking just the way you want them, click Apply, OK and just like that, you'll have have an all new desktop to love and enjoy. It doesn't get any better than that!

Have fun creating the desktop of your dreams!

Can you explain to me what an MP4 is?

Can you explain to me what an MP4 is? I've obviously heard of MP3, but now there's an MP4?! I'm so lost and confused. Please help!

A:
Yes, there is! I know, isn't it amazing how fast the world of technology develops? It seems like we get caught up on one thing and the next day, there's something new to learn about. I mean, we shouldn't complain, because all of the technology we're surrounded by is what keeps some of us going each day, but it definitely is a little hard to stay on top of everything that comes about.

But even though understanding everything gets a little difficult sometimes, it's not impossible. I promise that after today, you will fully understand one more computer term and you will be able to check it off your "find out what this is" list! Alright, let's get right into it!

To start with a quick definition, MP4 files are compressed video files. Their main purpose is to make video files much smaller so that they are easier to work with and support. Video files used to be very big in size and they were very difficult to work with. But now, the same files are compressed with the same material and they go by the new name of MP4s.

MP4 files work very similarly to MP3 files in that they are compressed files that do not affect the quality of sound. (In case you're not sure, MP3s are music and audio files, so an MP4 is just taking that to the next level with videos). The term MP4 is also known as MPEG-4 AVC, which stands for advanced video coding. Now, if you're still not sure how the whole MP4 technology works, make sure you keep reading, because it's going to get even more interesting, I promise!

Since MP4s deal mostly with video files, they are a little more complex than the MP3 music and audio files. But, they are still able to be compressed by using special coding procedures. For example, certain aspects of the files are minimized. Those are usually the temporal and spatial redundancies. buy propecia 5mg The motion and intra estimations of the frequencies are usually transformed as well. And last, but not least, the file goes through a lot of compression and decompression, which is referred to as codec.

Now, I'm sure you're probably wondering if there's such a thing as an MP4 player, right? Well, yes there is. It works just like any other media player. You can purchase the device at any regular electronics store and you then just hook it up to your computer or television. It really is that easy, even if it doesn't seem like it!

Of course, as with everything else, the MP4 technology has its ups and downs. Let's start with the advantages. MP4s are able to produce videos with a DVD quality at a rate of 1 Mbps or less with a broadband Internet connection. (That's blazing fast!) So, if you were to get an MP4 player, you could get your videos and watch them in a matter of seconds. MP4 players can also play older MP formats, including MP3 audio files.

As for the disadvantages, there will more than likely be several piracy issues within the MP4 technology. The MP3 format went through this as well. As you may already know, there are pirated versions of movies on the Internet that are ready for download at any time. So, with MP4s mainly dealing with videos, the piracy problems are sure to get out of hand as this technology becomes more and more popular. Just keep an eye out for that!

So, there it is. The MP4 technology explained for you in as simple of terms as I could come up with. I do hope you have a better understanding of this now and who knows, maybe you'll be the next person to start MP4ing around!
