I needed to take a screenshot on my MacBook and didn’t find a print screen kind of key so I went searching on the net but all what I found was
treaky key-combinations really complicated, so I tought, things are supposed to be simple like most of the things that apple does.

So I went to my Applications/Utilities folder and to my susprise I found an utility called Grab.
Grab is a very simple application , you just have to execute it,go to the capture option,choose Selection and voila your picture will be taken.

Once your picture is been taken you can save it into a file.

I hope this is been informative for you and I’d like to thank you for reading it.

On the 23rd October 2001, the world was introduced to a technological phenomenon that would change the way people listen to music forever. The release of the iPod was much anticipated and it did not let anyone down.

The first iPod released had a capacity of 5GB which was enough for the user to have 1000 songs on. Second and third generation iPod were subsequently released in 2002 and 2003 respectively with slight improvements to make the product more user friendly.

By the time the fourth, fifth and sixth generation models had been released, the iPod had become very sophisticated with memory of up to 160GB available for users to upload their favourite songs as well as films and episodes of their favourite programmes. The iPod has well and truly become the market leader in MP3 players.

As well as the classic styles, Apple also released other versions of the iPod including the Mini, which was a smaller, lightweight version of the classic with less memory. The Nano, slim and sleek and ideal for those constantly on the go, and the iPod shuffle which was a screen-less version that was designed for those exercising as it was very small.

On the 5th September, Apple once again raised the bar. The iPod Touch was released which had Wi-Fi capabilities and a Multi-touch interface. Internet access was perceived to be the only thing missing from the product so Apple corrected this and made it available providing a Safari browser.

Another reason the Apple iPod gets good reviews is for the accessories it provides. One of the most successful has been the iPod Hi-Fi; many users flocked to the shops to buy the product that was a docking station for the iPod that allowed the user to play the songs on a high quality sound system.

Added to this, the release of the iPhone and iPhone 3G means that Apple are set to have a good Christmas with many of their products being at the top of Christmas lists.

With new faster processers, bigger hard drives and new larger LCD televisions building a media center computer has become more and more practical. A media center computer can record multiple television shows at one time, can organize all your music and pictures and can also be used as a normal computer. They are definitely very cool. However, before you decide to build your own media center here are ten quick tips…

1. Consider building a machine with a dual core or quad core processor. The multiple processing threads will be very useful when recording multiple programs and watching a program at the same time. A fast multi core processor is a must if you plan on watching and recording hi definition TV.

2. Don’t skimp on the RAM. A good media center will have at least 2GB of ram and should probably have up to 4GB. The ram will help keep things moving quickly while you are recording programs.

3. You can never have enough hard drive space. With high definition TV becoming more of a standard you are going to want to consider having large amounts of hard drive space on your machine. I wouldn’t build a machine that had less than a terabyte of hard drive space.

4. To increase performance considering using a raid configuration for your hard drives. Using raid zero along with high speed SATA hard drives can help you improve video performance and can prevent recording errors.

5. Get good TV tuner cards with built in hardware encoding. Tuner cards with MPEG hardware encoding will take a load off your processor when they record tv shows, this will help ensure that you won’t get any skipping or problems in your recorded output. I use Hauppauge cards in my machine and they work great.

6. Invest in a good decoding program. The software decoder software offered by Nvidia does a good job on my media center. However, I tested four or five different ones before I found one that operated the way I wanted with my hardware configuration. Be prepared to test some different options before you settle on the one that will work best for you.

7. Don’t forget to order the remote control. A media center without a remote control is a travesty. These computers are designed to operated while you sit back on your couch. The remotes don’t cost that much and they work great.

8. Buy the best video card that you can afford. The better the video card that you have the less chances you have that you will have problems with playback. Before you buy your video card also make sure to check the list of Media Center approved cards. If the card isn’t on there you might want to avoid it. Also make sure that you buy a video card that has a high definition output that matches your TV (either DVI or HDMI are the best).

9. Get a good audio card that is capable of feeding source audio to your receiver or your speakers. If you plan on outputting 5.1 or 7.1 data from DVD’s you are going to want to make sure that the sound card that you pick has an optical or digital coax output. You might also consider buying a card that will convert all the sounds used on your computer into a 5.1 or 7.1 digital audio feed.

10. Be prepared to play with your configuration and build. Unfortunately, building a media center is not an exact science and there is usually quite a bit of tinkering involved in getting a stable fully functional system. If you aren’t comfortable playing with the settings and the drivers to get things to work you might consider buying a prebuilt media center and have someone else do the testing and configuring for you.

I have been running windows XP media center edition for quite a while now and I love it. I have built two different media centers and they have both been a blast. Try it for yourself and see.

Transit-time meters, as the name implies, measure the difference in travel time between pulses transmitted in the direction of, and against, the flow. This type of meter is also called time of flight and time of travel.

In the example shown in Figure 1, the sonic beam is at a 45º angle, with one transducer located upstream of the other. Each transducer alternately transmits and receives bursts of ultrasonic energy; the difference in the transit times in the upstream vs. the downstream directions (TU - TD) measured over the same path can be used to calculate the flow through the pipe:

V=K*D/Sin2θ*1/(To-t)²∆T

where:

V= Mean Velocity of flowing fluid

K= Constant

D= i.d. of pipe

θ= incident angle of ultrasonic burst waves

To = zero flow transit time

∆T = T2-T1

T1 = transit time of burst waves from upstream transmitter to downstream receiver

T2 = transit time of burst waves from downstream transmitter to upstream receiver

t = transit time of burst waves through pipewall and lining

This equation shows that the liquid flow velocity is directly proportional to the measured difference between upstream and downstream transit times. Because the cross-sectional area of the pipe is known, the product of that area and the flow velocity will provide a measure of volumetric flow. Such calculations are easily performed by the microprocessor-based converter. With this type of meter, particles or air bubbles in the flow stream are undesirable because their reflecting qualities interfere with the transmission and receipt of the applied ultrasonic pulses. The liquid, however, must be a reasonable conductor of sonic energy.

Figure 2 shows three placements that can be used for the two transducers. All are identified as single measuring path because the sonic beam follows a single path, and in all three the two transducers are connected by cable to a converter that can output a 4-20 mA DC signal. The selection of one configuration over another is dictated by several factors associated with the installation, including pipe size, space available for mounting the transducers, condition of the inside pipe walls, type of lining, and nature of the flowing liquid.

The Z configuration places the transducers on opposite sides of the pipe, one downstream of the other. Generally, the distance downstream is ~D/2, where D = pipe diameter. The converter uses specific data on piping parameters to compute the optimum distance. The Z method is recommended for use only in adverse conditions such as where space is limited, the fluid has high turbidity (e.g., sewage), there is a mortar lining, and when the pipe is old and a thick scale has built up on the inside wall that tends to weaken the received signals. It is not recommended for smaller pipes, where its measuring accuracy tends to degrade.

In most installations, the V method is recommended, with the two transducers on the same side of the pipe about a pipe diameter apart. The rail attachment that can be clamped on the pipe facilitates sliding the transducers horizontally along the pipe and positioning them the calculated distance apart.

The W method should be considered on pipe 1½ in. down to ½ in. dia. Its main limitation is a possible deterioration in accuracy due to buildup of scale or deposits on the pipe wall-note that the sonic signal must bounce off the wall three times. Turbidity of the liquid also could be harmful since the signal has a longer distance to travel.

How to put adsense on your wordpress blog.
There are lots of plugins that work with adsense but the one I use is provided by the following guy at:
Adsense injection

It works pretty well and the installation is as simple as follows:

change directory to /public_html/wp-content/plugins like

1)cd public_html/wp-content/plugins
2)wget http://www.biggnuts.com/wp-content/code/adsense-injection-20.zip
2)unzip adsense-injection-20.zip

Go site options and enable plugins

Now you should see the option plugins enabled next to Users and Settings.

Now go and enable the plugin by checking the checkbox and hiting the activate button.

If you click on settings you should now see a new link named adsense located next to Miscellaneous

Go there and customize the look and feel of your ads.

And now you are ready to start making some revenue with adsense.

I truly hope this article is being informative for you.

1. I love the command line so the first thing I would do is to go open my shell connection, enter the server where I want to intall wordpress like

{Change forder to get to the target directory}

cd public_html

{Download the script}

wget http://mu.wordpress.org/latest.zip

{Uncompress the script}

unzip latest.zip

{Change to the folder generated in my case wordpress-mu-2.6.5}

cd wordpress-mu-2.6.5/

{Move all the contents to the public_html directory}

mv * ../

{Get back to the root directory}

cd ../

{Change permissions for the .htaccess file} –!Important if you don’t do this later on you will regret it , believe me.

chmod 777 .htaccess

Open your browser:
type in your url:

If everything is allright you should see a sort of wellcome message and at the footer you’ll see a warning that will tell you
to apply a quick fix in order to continu with the installation.

quickfix proposed by the system:
chmod 777 /home/bmxforce/public_html /home/bmxforce/public_html/wp-content/


Refresh your page once done

If everything is allright you should now see a form you need to fill in with the data we are gonna get now at your
cpanel admin normally located at http://www.yourdomain.com/cpanel

Here you have to find the “mysql” icon , click on it and create:
a) a database
b)an user
c)grant all permissions to user on the newly created db

Go back to your domain and complete the form , hit submit and voila!, by now you should be up and running with your worpress mu.
