Apple has included a nice app in Mac OS X Lion that you can use to gather all kinds of diagnostic information from your wireless network. The app provides really technical information about the network that most users might find puzzling perhaps that is why Apple decided to hide it. Today’s tip will show you how to uncover this handy wireless network utility.

The app named Wi-Fi Diagnostics is in the /System/Library/CoreServices folder. The folder isn’t normally accessible to you so you need to get there by going to the Finder and either going to the Go menu and selecting Go to Folder or by using the keyboard shortcut Shift-Command-G. A dialog will open so that you can enter /System/Library/CoreServices and press Return. A folder will open and you will find Wi-Fi Diagnostics inside of it. Just double-click it to open it.

Once you launch the app it gives you four options:
  1. Monitor Performance which displays network signal strength, transmit power, noise level and data rate.
  2. Record Events which maintains a log of what is going on with your Wi-Fi network.
  3. Capture Raw Frames collects and retains information about all the data going into or out of your Mac via Wi-Fi.
  4. Turn on Debug Logs does exactly what is says – logs of debugging information is collected to help you troubleshoot your wi-fi network.
You can use this handy tool to troubleshoot and resolve Wi-Fi network problems or simply to impress your friends and family.

5 Android Apps you Need: App 5

This is the final post of a five part series. Read the fourth post here.


So we've been pretty productive with our first four apps, and it's time to have some fun. If you follow sports of any kind, this free app from ESPN.com, is a great download. Called ESPN ScoreCenter, the app puts sports news, videos, scores, and more, in the hand of the user.

The app allows you to what's going on in tens of different leagues, including the big ones like NFL, MLB, and NBA, and the smaller ones, like Formula 1, NCAA Water polo, and Cricket. The app offers live scores, news, videos, and more for free, ad-free, from ESPN.

LauncherPro for Android
Although the design's not the prettiest, it's definitely a lot better than many other apps, making this sports-lover's app a sure download. It can be downloaded for free from the Android Market, or ESPN.com.

Now, I promised in the App 2 post that App 5 would contain a special bonus app. So, here goes.

Everyone knows that User Interface design isn't one of Android's strong points. It may be a powerful system, but iOS leaves Android in the dirt as far as UI. The good thing about Android, is that you're not stuck, and here's an app that'll make your phone just a little more pretty.

A free app from a developer named Federico Carnales, LauncherPro completely changes the look of your Android device, hopefully for the better. It is also extremely customizable, so check out the pics below, and see if you like it. If you do, it's a free download from the Android Market.


Hope you enjoyed this series, bye for now.




[HOW-TO] -Jailbreak Using Redsn0w 0.9.9b1


SOURCE: Cydiahelp
The iPhone Dev Team today released a major update, Redsn0w 0.9.9b1, which they’ve promised to release with so many major improvements and features. Redsn0w 0.9.9b1 is now available for download with many major improvement and features. Below, we’ve made a quick walk-through inside the Redsnow 0.9.9b1 version.

Redsn0w-0.9.9b1-2011-09-19-17-23.png
Once you start Redsn0w 0.9.9b1, you get a totally new screen asks you to choose either “Jailbreak” or “Extras”. Once you get to Extras, you’ve a lot of options to do.
Redsn0w-0.9.9b1-2-2011-09-19-17-23.png
First of all, Redsn0w 0.9.9b1 extras include the Just Boot option which is made for those tethered-jailbroken devices. Tethered means you have to connect your device to your computer every time it reboots and choose Just Boot option from Redsn0w so it opens again.
Second option in Redsn0w 0.9.9b1: Pwned DFU, this option is made for those restoring via iTunes using custom IPSW firmwares cooked by Sn0wbreeze or PwnageTool. Putting your device in Pwned DFU mode will bypass so many errors that would appear without it.
Recovery fix is the next option. It’s the same as many apps as Recboot and TinyUmbrella which allows you to get kick your device out of Recovery mode (or enter it) which may be caused by iTunes errors while restoring.
The most important option is that SHSH Blobs, it includes many options inside it. Here’s the options:
  • Fetch - fetch current partial blobs on your iOS device.  Should complete in under 10 or 15 seconds.  Puts the set PARTIAL of blobs on your computer as a plist.  Checks if Cydia already has a full set for this device and build.  If not, it submits this partial set and returns Cydia’s acknowledgement or rejection.
  • Verify  – cryptographically verifies existing blob files from either redsn0w, TinyUmbrella, or Cydia server.  You can select a whole bunch of blobs to verify at once if you want (like the TinyUmbrella directory).
  • Submit  - both verifies and submits one or more blob files to Cydia.  This lets you copy your entire TinyUmbrella cache of blobs up to the Cydia server.
  • Query - queries the Cydia server for all available full or partial blobs for a given set of ECIDs.
  • Stitch – stitches either FULL or PARTIAL blobs to a STOCK or CUSTOM IPSW.
Redsn0w 0.9.9b1 also includes an option called Select IPSW which is for picking non-public IPSWs, or overriding auto-detection.
Need more clarification? Well, we’ve made a quick guide to jailbreak iOS 5 beta 7 using Redsn0w 0.9.9b1:
Redsn0w 0.9.9b1 Guide:
STEP 1: Download iOS 5 beta 7 firmware for your iOS device from here then download Redsn0w 0.9.9b1 from the links given at the end of the page.
STEP 2: Open Redsn0w 0.9.9b1 and then choose Jailbreak to be able to jailbreak your iOS device:

STEP 3: Now you’ll have to follow the on-screen instructions to enter the DFU mode.
Guide2-2011-09-19-17-23.png
STEP 4: Once Redsn0w identify your iOS device, you’ll get a message telling you which IPSW file it needs.
Guide-2011-09-19-17-23.png
Note: In our case you’ll need to get back to Extras and Select IPSW as we’re on beta but for public firmwares, you’ll be able to select it directly.
STEP 5: Finally, you’ll select Install Cydia and then Cydia will be installed successfully on your iOS device.

One of our team members have made a quick video walkthrough for our readers, hopefully watch it:

Has Social Media come of age?


One of the main characteristic of any mass media is its ability to impact the society. Be it the newspapers, television or radio, each had played its part, in terms of changing views and shaping the society.

In the recent past, there have been many news articles about the impact of social media in the civil society movements… Be it Coffee Party in America, The elections in Iran, the civil movements in Tunisia, Egypt (#Twitterrevolution) and other Arab countries...or, closer home, the Team Anna’s anti corruption movement in India…. Social media usage has become an important tactic in terms of spreading awareness and mobilizing support.

The question is - has social media come of age?

If you look at the history of mass media… it has always been associated with politics. In fact, it is referred to as “fourth estate”, the other 3 being Executive, Legislative, and Judicial. Traditional mass media was and has been controlled by a few (Just imagine, more than 90% of mass media consumed in the US is owned by just 6 media companies), and is limited by its ‘real estate’ – print area, bandwidth, or time… Mass media has always been used as a mass communication system to reach the public.

The relatively new Social Media however is built on a different model. The characteristic of social media is that it is not limited by any ‘real estate’, and more importantly is a mass communication system for the public. On the same platform, one can either broadcast or send a personal message.
There are 3 distinctive features for any mass media –

- The reach
- The information
- Influence on the people/society

The Reach:

The Internet boom took place in most countries during the mid 90’s. Majority of the social media consumers are the people who grew up with the Internet. Of the 640 Million Facebook users, more than 70% of the users are under 34 years…and close to 50% of the users under 25 years (source: checkfacebook.com). According to worldinternetstats.com, there are 2.1 Billion internet users in the world. If we assume that at-least 40% of these users are on social media, we are talking about close to 800 Million users globally. Looking at the sheer numbers, the social media surely fits into being called a mass media

The information:

Any mass media is known by the quantity and quality of information it disperses. Nobody can doubt the quantity of the information… be it a foursquare update on one’s check-in into a local bakery, or a Facebook update of a traffic jam on your way to work, or a tweet about environmental impact of discarded laptop batteries, linking to a blog or YouTube video..there are millions of such updates happening every minute, globally

But, when it comes to quality of information, most of the stuff seen in social media is found wanting. It is known fact, that ‘noise’ is the biggest factor that impacts effective flow of communication. In the traditional media, information flows from a professional few, and a lot of ‘filters’ before it is actually transmitted to the users… But in social media, the number of professionals and the reason for filters do not exist. Hence, there is a lot of information created, but very little percentage of that is of substance… It is early days of social media, but ‘filters’ for information has already begun… be it the search engine algorithms, or the social bookmarks, or user reviews… it is just a matter of time, before the perfect mouse trap in terms of social media filters is created

Influence on the society:

The influence of mass media shapes our concepts of who we are, what is important to us, and how we live our life. Majority of the social media users are the youth. Most information in the social media is created by the youth for the youth. Where as in today’s world the society is being led and shaped by people with experience. Most Decision Maker’s in our society still belong to the classic era of media, and have only adapted to social media (or for that matter, Internet) pretty late. However, the divisional lines between traditional media and social media are diffusing. It is a world of convergence media; Where-in each media feeds of the other for information seeking and broadcasting… You’ll find traditional media tweeting about their articles and liberally seeking information from other people’s tweets… so too, you will find tweets and updates based on the information the user gets from print, TV or radio.

So while, in today’s context, social media may not directly influence the society at large… it can indirectly influence the people who influence the society… (eg. the traditional media). However, as more and more internet generation people becomes decision makers…the impact of social media on the society and popular culture would become strong

So has social media truly come of age?? I’d dare say, yes. However, there are some things that social media needs to overcome to be accepted as a powerful and influential medium by all… The concentration of the users should not be skewed to few locations, there should be stronger filters to reduce the noises, and more importantly wait for few more years

Cheers
