The PlayStation 4 hits shops today in the UK, one week after the Xbox One was released. For those who aren't gaming aficionados but want to know the differences between the consoles, we're here to help with the basics.

Which is cheaper?

PlayStation 4 at £349, Xbox One is priced at £429.

Which looks better?

They're both black, rectangular boxes. But the PlayStation 4 is less chunky than the Xbox One, and looks slightly sleeker. Both use a matte and gloss finish.

Which offers more?

The Xbox One comes with its camera, the Kinect 2.0, the PlayStation 4 camera costs £45 extra. With a subscription, PlayStation also offers free games every month, where Xbox One will only offer discounts. Xbox One comes with Skype, but both have Netflix and Lovefilm. Sony are rumoured to be releasing a bundle pack before Christmas, which will include a PS Vita – so you can play games remotely from the TV.

How much will it cost to play online?

PlayStationPlus costs £39.99 for a one-year subscription and £11.99 for a 90-day subscription. Xbox Live Gold is £39.99 for 12 month subscription, £14.99 for 3 months, or £5.99 for one month.

How much will the games cost?

There were originally some complaints that some PS4 games were over £60, but now it's been announced that cross-platform games will cost the same on both consoles' digital stores.

Which has the better launch games?

Xbox One: Forza Motorsport 5 is the one to beat for racing fanatics, Ryse: Son of Rome shows off an incredible landscape and combat that relies on good timing, and Zoo Tycoon is adorable, as you play as the manager who can get involved with tending to the animals.

PlayStation 4: Killzone: Shadow Fall shows off the PS4's graphics, Resogun (free with PlayStation plus) will take you back to days of gaming yore with a modern edge on a Space Invaders style, and Knack is an old-fashioned playable platformer.

Who will have the better games in future?

PlayStation 4 have confirmed developers Naughty Dog will release an Unchartered game for PS4, plus Octodad: Dadliest Catch (the clue is in the title) will be out next year.

Xbox One will release Kinect Sports next year, plus EA and Respawn Entertainment's exciting upcoming title Titanfall should be released early 2014.

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

SEN-1327 LPG Gas Sensor Module

The SEN-1327 LPG Gas Sensor Module is designed to enable LPG detection interface to Microcontroller without ADC Channels. It allows to determine when a preset LPG gas level has been reached or exceeded. Interfacing with the sensor module is done through a 4-pin SIP header and requires One I/O pin from the host microcontroller.

The onboard microcontroller provide initial heating interval after powerup and then starts to meassure LPG sensor output.If it found the LPG contents above setted value, it will inform the Host controller by pulling the Output Pin to High and Starts to blink a onboard status LED. The sensor module is mainly intended to provide a means of comparing LPG sources and being able to set an alarm limit when the source becomes excessive.

SEN-1327 module features

Uses the MQ-6 LPG Gas Sensor

Technology News : Linux bug - Comes to Android

Android users have been warned that a recently-discovered Linux bug has been modified to work on Android smartphones and tablets.

Perhaps not the easiest threat to remember, CVE-2013-2094 is a vulnerability that allows criminals to escalate privileges to a point where they can, effectively, achieve complete control of a device.

The threat exists on the Android platform due to the fact that Android was developed using Linux, and so many Linux vulnerabilities could potentially be exploited on Android.

The Linux vulnerability originally affected systems running on the 2.6 version of the Linux Kernel. In Android, Jelly Bean (version 4.2) uses version 3.0 of the Linux Kernel, although previous versions were built upon 2.6. This doesn't explicitly mean that Jelly Bean devices aren't at risk, but it does mean that tablets or smartphones using older versions of Android are more likely to be.

Unfortunately, for devices using older versions, any threat has little chance of going away without an update to resolve the issue. That's a problem if a device is continually out of date, but even more so if hardware receives no support or OS updates after release.

In regards to the exploit itself, the Symantec Connect Blog explains the seriousness of privilege escalation software: "Privilege escalation exploits are particularly dangerous as they can allow cybercriminals to gain complete control over the compromised device. The Android operating system normally sandboxes every application so they cannot perform sensitive system operations or interfere with other installed applications".

Adding to that and highlighting potential issues users might face, the blog states, "In the past, we have seen malware use privilege escalation exploits to access data from other applications, prevent uninstall, hide themselves, and also bypass the Android permissions model to enable behaviours such as sending premium SMS messages without user authorization."

Android users should take steps to avoid allowing malware using the CVE-2013-2094 vulnerability – or any other exploit – to gain access to devices. To protect yourself and reduce the risk to your Android or smartphone or tablet you can do the following…

Ensure your Android smartphone or tablet has the latest version of Android installed (if available)
Restrict app installs to those from Google's Play Store
Protect your device with Norton Mobile Security, ensuring the latest update is loaded.

Together, these three precautions will ensure that you minimise the risk as much as possible, while having help on hand to remove any malware which seeks to give itself free reign.
