Most important differences between an Intel Core i3, i5 and i7

 most important differences between an i3 and i5 processors:

1. Intel Turbo Boost is a technology that can be found on Intel® Core i5 & i7 processors only. It is important to mention that this feature helps the processor to increase its clock speed (provides a boost of power) when the system needs it in order to complete a specific task.

 

2. You can find the i3 processors with 2 cores and 4 threads. In the other hand, the i5 processors can be found with 4 cores and 4 threads.

 

3. Intel® Hyper Threading Technology is available on i3 & i7 processors only. This feature can be available on i5 processor for portable versions only (processor laptops). This feature uses processor resources more efficiently, enabling multiple threads to run on each core. As a performance feature, Intel HT Technology also increases processor throughput, improving overall performance on threaded software.

 

4. The higher the number, the better performance on processors. It mean that i5 will have better performance than i3 and i7 processors will also have better performance than i5 & i3 processors.

the difference between an Intel Core i3, i5 and i7 in terms of cores

The more cores there are, the more tasks (known as threads) can be served at the same time. The lowest number of cores can be found in Core i3 CPUs, i.e., which have only two cores. Currently, all Core i3s are dual-core processors.

Currently all Core i5 processors, except for the i5-661, are quad cores in Australia. The Core i5-661 is only a dual-core processor with a clockspeed of 3.33 GHz. Remember that all Core i3s are also dual cores. Furthermore, the i3-560 is also 3.33GHz, yet a lot cheaper. Sounds like it might be a better buy than the i5. What gives?

At this point, I'd like to grab the opportunity to illustrate how a number of factors affect the overall processing power of a CPU and determine whether it should be considered an i3, an i5, or an i7.

Even if the i5-661 normally runs at the same clockspeed as Core i3-560, and even if they all have the same number of cores, the i5-661 benefits from a technology known as Turbo Boost.

Tech Buzz; What's the difference between an Intel Core i3, i5 and i7?

Core i3, Core i5, Core i7 — the difference in a nutshell

If you want a plain and simple answer, then generally speaking, Core i7s are better than Core i5s, which are in turn better than Core i3s. Nope, Core i7 does not have seven cores nor does Core i3 have three cores. The numbers are simply indicative of their relative processing powers.

Image credit: Intel.

Their relative levels of processing power are also signified by their Intel Processor Star Ratings, which are based on a collection of criteria involving their number of cores, clockspeed (in GHz), size of cache, as well as some new Intel technologies like Turbo Boost and Hyper-Threading.

Core i3s are rated with three stars, i5s have four stars, and i7s have five. If you're wondering why the ratings start with three, well they actually don't. The entry-level Intel CPUs — Celeron and Pentium — get one and two stars respectively.

Note: Core processors can be grouped in terms of their target devices, i.e., those for laptops and those for desktops. Each has its own specific characteristics/specs. To avoid confusion, we'll focus on the desktop variants. Note also that we'll be focusing on the 2nd Generation (Sandy Bridge) Core CPUs.

Tech Buzz: Microsoft sells over a million Xbox Ones in 24 hours, on par with Sony PlayStation 4

Microsoft sells over a million Xbox Ones in 24 hours, on par with Sony PlayStation 4

Microsoft Corp sold over 1 million of its new Xbox One game consoles within 24 hours of their hitting store shelves on Friday, on par with Sony Corp's PlayStation 4 despite launching in far more countries.

The new console, which launched in 13 countries, set a record for first-day Xbox sales and is currently sold out at most retailers, Microsoft said in a statement.

Sony said it sold 1 million PS4 units in 24 hours after launching last Friday in just the United States and Canada. The PS4 expands to other regions, including Europe, Australia and South America, from November 29. It then hits Japan in February.

Microsoft is locked in a console war with Sony this holiday season. The software giant hopes the Xbox One not only entices gamers but attracts a broader consumer base of TV fans and music lovers with its interactive entertainment features and media apps.

"We are working hard to create more Xbox One consoles," said Yusuf Mehdi, corporate vice president of marketing and strategy at Xbox.

Robert W. Baird & Co analyst Colin Sebastian has said he expects shipments of 2.5 million to 3 million units for both the Xbox One and PS4 in the fourth quarter.

Both the PS4, priced at $399 in the United States, and the Xbox One, with a price tag of $499, offer improved graphics for realistic effects, processors that allow faster game play and a slew of exclusive video games.

Tech Buzz: Create Wifi Hotspot in Ubuntu 12.4/12.10 for smart phones(android ) phones laptops

for video:

http://www.youtube.com/watch?v=U59PymP-K6Y


1. First of all you should make sure, that your wifi adapter supports infrastructure hotspots. If you used connectify on your windows system and it worked, skip this step.

open terminal and type: sudo lshw | less

find -network section and make sure that driver is ath5k or ath9k, this solution will only work for those drivers, but should fit the needs for the most laptop users.



2. We now need to install 2 additional tools to make out hotspot, 1st one is hostapd(hotspot server), 2nd one is dnsmasq(dns dhcp server)

in terminal type: sudo apt-get install hostapd dnsmasq

3. stop those services if started already, and prevent them from starting on system start up.

in terminal type:
sudo service hostapd stop
sudo service dnsmasq stop
sudo update-rc.d hostapd disable
sudo update-rc.d dnsmasq disable

4. Now we need to set up config files.
in terminal type: sudo gedit /etc/dnsmasq.conf
or sudo kate /etc/dnsmasq.conf if you use kde

add those lines to the config file
Code:

# Bind to only one interface
bind-interfaces
# Choose interface for binding
interface=wlan0
# Specify range of IP addresses for DHCP leasses
dhcp-range=192.168.150.2,192.168.150.10

5. hostapd config

in terminal type: sudo gedit /etc/hostapd.conf

and add those lines

Code:

# Define interface
interface=wlan0
# Select driver
driver=nl80211
# Set access point name
ssid=myhotspot
# Set access point harware mode to 802.11g
hw_mode=g
# Set WIFI channel (can be easily changed)
channel=6
# Enable WPA2 only (1 for WPA, 2 for WPA2, 3 for WPA + WPA2)
wpa=2
wpa_passphrase=mypassword

You can change ssid name and password for anything you want here. Current config will create hotspot named myhotspot with mypassword password.

6. Now create anywhere you want a file named start.sh
edit it with any text editor like this:

Code:

#!/bin/bash
# Start
# Configure IP address for WLAN
sudo ifconfig wlan0 192.168.150.1
# Start DHCP/DNS server
sudo service dnsmasq restart
# Enable routing
sudo sysctl net.ipv4.ip_forward=1
# Enable NAT
sudo iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
# Run access point daemon
sudo hostapd /etc/hostapd.conf
# Stop
# Disable NAT
sudo iptables -D POSTROUTING -t nat -o ppp0 -j MASQUERADE
# Disable routing
sudo sysctl net.ipv4.ip_forward=0
# Disable DHCP/DNS server
sudo service dnsmasq stop
sudo service hostapd stop

You will probably need to change ppp0 in this to eth0 (or any other number which refers to your wired connection.

7. Last step. Now you can start your hotspot by starting our script. just run it using sudo sh
for me it looks like this sudo sh /home/ogyct/Desktop/start.sh because I have it on my desktop

Sachin Tendulkar Farewell speech: Tendulkar signs off with moving speech

'All my friends, settle down. Let me talk, I'll get more and more emotional.' The crowd goes berserk out there. 'My life between 22 yards in 24 years, it's hard to believe that it's coming to an end. I would like to thank all the people who have helped me in my life to get here. I have a list in my hand, please forgive me if I miss out on a few names. First, my father, he passed away in 1999. He was very key for my career. He gave me freedom, and he told me, chase your dreams and don't find shortcuts. He also told me to be a nice human being. My mother, I don't how she dealt with such a naughty guy like me. She took care of me to be healthy. She started praying for me even before I started my career and I think those prayers gave me strength. In my school days, I used to stay with my uncle and aunt as my school was far away. They treated me like their son. They gave me enough food so that I can play well. My eldest brother Nitin, he used to tell me, I know you'd do everything right and I have the confidence in you. My sister Savita, she presented me my first bat which was a Kashmir Willow. She is one of the many who fast when I bat. Ajit my brother, I don't know what to talk about him. We've lived this dream together. It all started from the age of 11, he took me to Achrekar sir, my coach. And my life changed. Even last night, he called me and we were discussing my dismissal. Even after I finish, we discuss technique. We've had arguments and disagreements. If I had not done that, I would have been a lesser cricketer. The most beautiful thing to have happened is, in 1991, I met my wife Anjali. I know she was a doctor. When we decided to make a family, she said, you continue with your cricket and I'll take care of the family. Without that I think I couldn't have played so much cricket. Thank you for all that you've done and it is the best partnership I've had in my life. Then Sara and Arjun are two precious diamonds in my life. Daughter is 16 and son is 14, time has flown by. I wasn't able to be with them for the birthdays, annual days, sports days. Thanks for understanding all that, both of you have been so special to me. I've not spent enough time with you in the 14-16 years, but I promise you that for the next 16 and beyond, everything is for you. My in-laws have been very supportive and caring. I discuss various things with them, we have a strong family and I've taken a lot of advice from them. The important thing they did was allow me to marry Anjali. There have been a lot of friends who have supported me in the last 24 years. They have made terrific contributions. They have been with me when I was stressed, leaving their work and coming to bowl to me when I called them. I thought my career was over when I was injured, but my friends called even at 3 AM and made me believe that it was not over. My career started at 11. My brother took me to Achrekar sir and that is the best to have happened to me. I was extremely delighted to see Achrekar sir in the stands. Sir would be taking me on his scooter all over Mumbai to ensure that I get enough match practice. On a lighter note, he's never said well played to me so that I don't get complacent.'

Tech News -Mangalyaan: Date of entering into the orbit of Mars

Mangalyaan will enter Mars orbit in September 2014

Mangalyaan, the satellite India launched on Tuesday afternoon in its first mission to Mars, will enter the orbit of the Earth's red neighbour in September 2014.

Scientists at the Indian Space Research Organisation (ISRO) exhaled only after the satellite separated from the Polar Satellite Launch Vehicle (PSLV) rocket, 2700 seconds or about 45 minutes after launch and entered the earth's orbit.  

The launch rocket "has placed the Mars Orbiter spacecraft very precisely into an elliptical orbit around Earth," the chairman of the Indian Space Research Organisation K. Radhakrishnan announced from the control room.
