Reduce the File Size of Your Keynote Presentation

f you add a lot of multimedia content — such as photos and movies — to your presentation, your Keynote document might get very large.

There’s an easy way to reduce a Keynote document’s file size — by removing the unused parts of the media.

To reduce the size of a Keynote document:

Save your document.
Make sure no media files on the slide canvas are selected, and then choose File > Reduce File Size.
After you’ve reduced the file size of your Keynote document and then saved it again, you won’t be able to restore the images to a larger size or access the unused parts of your media files. It’s a good idea to back up your presentation before using this feature.

Internet Sharing on Network with a Mac

Internet Sharing on mac network is very easy and very simple with few steps only.
First thing you have to plan is how you want to share a i.e by Ethernet or by Airport.

Here i am going to receive my net through Airport and share through Ethernet.

Following are the steps:
First step: Go to system Preferences> Sharing> Internet Sharing.(here you will notice menu like to given below image..

So share your computer from Airport to computers using Ethernet must be my combination(so i will tick Ethernet in the tick box just near to Ethernet) and with a pop up i will enable it.

Second Step: Go to system Preferences> Network> create a new location> Join your Airport Network (i.e wireless network) then connect your Ethernet and configure if it is not. you might see the Ethernet might be the first option (if its Airport its Done.) we need to create it as secondary so that it can share the received net connection below set will help...
1) Click on and a pop up will appear.
2)Select Set service order and
3)With Selection window of Set service order drag the Airport as priority and click ok...


Its done..
your network internet sharing no mac will be active...If not try putting your DNS server on you Ethernet settings.

HP Slate vs Apple iPad

iPad Presale Begins on April 3rd2010 and HP launched a renewed Campaign for its slate Tablet PC might be with Windows 7 as its operating system,but so far the debate seems to center entirely around support for flash.

if try to compare it, we wont be because it has different class of audiences based on technology.

I think so With out flash as Apple iPhone and iPod works this product will also change the Market..

Phoenix-track and protect your precious Macintosh computer.

Phoenix (1.0), an ingenious software to help track and protect your precious Macintosh computer. Phoenix can pinpoint the location of the thief and collect vital details  to assist in the recovery of a stolen laptop! Upon connecting to an internet network, an authentication dialog will pop up requesting the user to enter a password. If the user fails to enter the correct password within the pre-defined time, hidden alerts (email and twitter alert) with location details will be sent out immediately to alert the owner.

How to wire your own ethernet cables

Required:
Cable - bulk Category (Cat) 5, 5e, 6 or higher cable
Wire Cutters - to cut and strip the cable if necessary
For Patch Cables:
RJ45 Plugs is an 8-position modular connector that looks like a large phone plug.
RJ45 Crimper
For Fixed Wiring:
RJ45 Jacks
110 Punch Down Tool

Recommended:
Wire Stripper
Cable Tester

About the Cable:
There are 2 kind of Cable UTP (Unshielded Twisted Pair) and Shield Twisted Pair cable with different Category , Two Type of Color Coding used i.e T568A and T568B.

T-568A Straight-Through Ethernet Cable

The TIA/EIA 568-A standard which was ratified in 1995, was replaced by the TIA/EIA 568-B standard in 2002 and has been updated since. Both standards define the T-568A and T-568B pin-outs for using Unshielded Twisted Pair cable and RJ-45 connectors for Ethernet connectivity. The standards and pin-out specification appear to be related and interchangeable, but are not the same and should not be used interchangeably.


T-568B Straight-Through Ethernet Cable

Both the T-568A and the T-568B standard Straight-Through cables are used most often as patch cords for your Ethernet connections.

If you require a cable to connect two Ethernet devices directly together without a hub or when you connect two hubs together, you will need to use a Crossover cable instead.

Subnet NEtworking

It not just easy,But not difficult too....

First Plan your requirement,i.e how many sub networks you need 2,3,4 according how many machine in each network. if you want around 60 machine in each network of 4 subnetwork. it very simple.

How calculation work

eg:
Decide the range of IP and Class of Network you wand A,B,C,D

Here i am taking the Range of Class " C" IP i.e 192.198.1.0-255
so my Subnet mask calculation will work like:
(255.255.255.0 - Standard Subnet mask)
Its converted into binary of eight decimal i.e 11111111.11111111.11111111.00000000(255.255.255.0)

The formula for figuring out the number of 'host' bits in a subnet mask is
2^n=(number of nodes ) (2^n means '2' to the power of 'n')
Since you know the number of nodes, you need to find 'n'.

Because you want 64 node(s), you want to leave 6 - '0' bits in the subnet mask since 64 = 2 ^ 6 (2x2x2x2x2x2).
This will give you the following subnet mask:

subnet mask: 11111111.11111111.11111111.11000000
Which is referred to as /26 or in dotted decimal notation as 255.255.255.192

So my SUBNET 1 will have IP Ranging from 192.168.0-63 were 0 is transmission ID and 63 Broadcast ID.
SUBNET 2 will have IP Ranging from 192.168. 64-127 were 64 is transmission ID and 127 Broadcast ID.
SUBNET 3 will have IP Ranging from 192.168.128-191 were 128 is transmission ID and 191 Broadcast ID.
SUBNET 4 will have IP Ranging from 192.168. 192-255 were 192 is transmission ID and 255 Broadcast ID.
