iPhone 4 has been hacked already ! It arrived in the markets just a few weeks ago. It seems Apple didn't fix a security hole properly.

Often, when I use computer applications that transfer files, process files, play files
I get players and programs that "nag" with the 1990s style "modal dialog box".
A single file in the queue of files is causing some kind of mishap, and the application stops processing completely until a "dialog box" has been processed by the end-user.

What I'd like to propose is a fix to this behavior, and it's conceptually very simple:
An enhanced status-bar, which can also act as an application-level event log and handler.

Suppose you move too much - keep travelling every now and then due to some or the other reason. Now you visit your relative and show them some photos from your mobile phone and now they want a printed copy of it for memory, and their printer is not working. So what do you do now ? Here's a nice product - a pocket printer, which you can carry in your pocket and print photos and probably bizcards whenever you need them.

Everyone is interested in understanding in detail - a computer network.

And we all know it costs lots of money to buy the required devices. This is many times not feasible.

With Apple drawing out its hands from Macworld, the final one becomes even more important. Lets have a look at what all the gossip is about..

Robots that are humanoid may be going in the wrong direction. In the future, many theorists believe, robots won't need to look like people to fit in. (David Guttenfelder, Associated Press)

The movie "Wall-E," a futuristic tale of a trash-compacting robot, has become a money-making machine at the box office. Here are some key components of robotics:

1. The word robot, coined by Czech playwright Karel Capek in his 1921 play "R.U.R. (Rossum's Universal Robots)," is based on the Czech word "robota," meaning forced labor or serf. The fictional robots in Capek's play were created chemically, not mechanically.
2. Here's a nightmare scenario: Robots learn to build new robots, replicating without human aid and eventually achieving world domination. In theory, at least, that could happen through nanotechnology, the science
   of manipulating materials on an extremely small scale. Nanotechnology expert Eric Drexler once envisioned tiny machines replicating out of control, overwhelming the Earth in a wave of "gray goo."
3. "Proprioception" is sometimes called the sixth sense. It means knowing where each part of your body is without having to look for it. This is natural for people, but very difficult for robots.
4. As household robots such as the Roomba vacuum cleaner gain popularity, clashes with pets are becoming more common. Los Angeles graphic designer Rob Sheridan has posted a YouTube video called "Puppy Vs. Robot! Epic Battle for Territorial Domination!" The video, featuring confrontations between Sheridan's pet Lola and a toy called Roboquad, has been viewed more than 2.4 million times.
5. Cyborgs--part man and part machine--are coming. In fact, some would say they're already here. Is a person with a heart pacemaker a cyborg? How about a person who attaches a cell phone to his ear? Scientists are working on a robot suit or exoskeleton that people could wear to increase their physical strength. The happy application: Disabled people might be able to walk. The darker side: Soldiers could fight longer and better.
6. Scientists are studying swarming behavior among robots--the collective actions of robots that have individual intelligence. Robot enthusiasts enjoy staging soccer matches between teams of machines, such as the Sony
   robo-dog Aibo. Daniel H. Wilson offers scarier swarming scenarios in his tongue-in-cheek but science-based book, "How to Survive a Robot Uprising." An army of robots that communicated with each other would be effective at
   hunting down people because if one robot spotted a person, all of them would instantly know where the person was. Wilson also postulates how all the appliances in a "smart home" could conspire to kill the owner.
7. The "Uncanny Valley" is a theory by Japanese roboticist Masahiro Mori suggesting that as robots become more humanlike, people's empathy with them increases. But Mori sees a drop-off--a valley--when the robot is not perfectly human but is alarmingly close and seems creepy, like the living dead. Filmmakers and critics have cited the Uncanny Valley as the reason some animation fails: It is neither close enough to reality nor far enough
   away to be comfortable to the viewer.
8. While androids--humanlike robots--dominate popular perceptions, many roboticists believe that the robots of the future will be limited-function machines that look nothing like people. One example is a snakelike robot being developed to find people trapped in the rubble of an earthquake.
9. The U.S. military may be struggling to sign up soldiers, but it's recruiting plenty of robots. Predator drones have become a key part of the arsenal, and robots are being used to defuse roadside bombs. The U.S. military's Defense Advanced Research Projects Agency sponsors a competition to develop an unmanned vehicle that can operate in urban environments. Congress has set a goal that one-third of the military's "operational ground combat vehicles" be unmanned by 2015.
10. Many Americans view robots as threatening, but the Japanese have fully adopted them, consistent with their Buddhist and Shinto principles. "If you make something, your heart will go into the thing you are making," Mori told the Tribune in 2006. "So a robot is an external self. If a robot is an external self, a robot is your child."

More than 550 new applications arrived for the iPhone and iPod touch this morning in iTunes' brand new App Store and more than 130 of them are available for free. Today we're taking a look at the best free applications for your iPhone and iPod touch, available once you've got iTunes 7.7 and the iPhone 2.0 software update installed.

Note: Most of the apps listed here work with both iPhones and iPod touch models, but we've noted where an app requires the iPhone's voice, SMS, or GPS capabilities to run.

Remote: Controls Your iTunes Library
The iTunes App Store's marquee freebie, the Remote app turns your iPhone or iPod touch into a remote control for your media library. Remote works almost exactly like the iPod application on your device—the main
difference being that rather than playing back music on your iPhone or iPod touch, you've got access to your entire iTunes library and you're playing it over your computer's speakers.
Google Mobile is Quicksilver for the iPhone/iPod touch
Google already has a fast and slick iPhone version, but this app is hyper-optimized for quick searching. Search-as-you-type results spin up for web pages, click-to-call business and residential phone listings, nearby stores and restaurants, and more—and Google Mobile's brought to you by the guy who made one of our favorite free launcher desktop apps, Quicksilver.
Jott: Transcribes Speech to Text
iPhone only: Free voice-to-text service Jott is a natural fit for an iPhone app, and its implementation here is pretty nifty. You can simply say a note into the recording interface (at right), and it'll show up in your Jott notes (or on Google Calendar, Remember the Milk, or Jott-connected applications). You can also simply type a note in, making the Jott app a quick interface for a lot of web apps. Managing all your notes with finger-swipe deletion is pretty handy as well.
Evernote
The universal stuff-gathering site Evernote gives you all the major tools of its desktop and web software in its iPhone app—add text, snap a phone cam shot, record a memo, or upload a photo, and it's all available for organizing, tagging, or searching later. New in this interface is a straight-forward voice recorder; if you'd rather have your audio transcribed, you can use the Jott app as a gateway to Evernote. Given that even free users of Evernote can have the service scan their pictures and extract visible text, Evernote's app makes your iPhone a serious universal capture device.
NetNewsWire
Users of desktop-based readers like NetNewsWire (Mac) or FeedDemon (Windows) have their reasons for sticking with them. NetNewsWire for iPhone syncs with either of those clients, meaning you won't read the same items twice. There's a "Clippings" feature for setting items aside for later (or when you'll be offline) that also syncs to your desktop, and the interface is straightforward—and that's about it. If you're a Google Reader addict, you're already set up with GReader's iPhone beta view.
Zenbe Lists
Free service Zenbe works as a multi-account mail organizer in its web form, but they've stuck with to-do-style lists for their iPhone app. Those lists, however, can be edited on any browser and synced back to your Zenbe account, or published on an iGoogle page. The real benefit, though, is sharing with other Zenbe Lists users. Anyone you share with can then edit and update your list and sync them back to you—a kind of nifty no-real-computer-required list wiki.
Yelp
The iPhone app for business review site Yelp takes good advantage of your location-aware device to dish up the details on nearby restaurants, bars, gas and service stations, and much more. There's a custom search function too, so you can always know when you're in the presence of, say, high-quality sushi while you're traveling, and how much reviewers say it's going to cost you. A great app for traveling, or just seeing what the hive says about your home town.
Save Benjis
Save Benjis (as in the face on the bills) makes it seriously convenient to compare prices on online purchases, or the gadget that's sitting right in front of you at the store. Type in a name, a product ID number, or other details, and you'll get a list back with links and prices from Amazon, NewEgg, and other online merchants. If you've ever wondered how much markup you're paying to grab that gear now, wonder no more. Saving Benjis also integrates well with Amazon for making actual purchases.
Talking Phrasebook (French, Italian, German, Spanish)
Translation tools and dual-language dictionaries are great, but sometimes, you really just need to ask "How much to park here?" in German. The Talking Phrasebook apps offer phrases you'll want to know translated from English to Spanish, French, German, and Italian, and you can click to hear them pronounced (or, perhaps, just have your iPhone speak for you).
Midomi
iPhone only: This one's not terribly productive—unless you're the type to spend far too much time trying to name that song you just can't remember. For those moments, or for proving a friend right/wrong, Midomi is a true gift. You can type in an artist or song name to get more info (and you can write it phonetically), but the true joy is in humming or singing a few bars into your iPhone, waiting a bit, then seeing your song title come back. You can also hold your phone up to the music itself, and Midomi will try to ID it. Seriously neat stuff.
Where
One of the most comprehensive location-aware apps in the Store, Where gives you all sorts of location-based information—like where the nearest restaurants, Zip cars, gas stations, and Starbucks locations are in relation to you. Enable Buddy Beacon to see nearby friends also using Where. Get to know the new place you're visiting—or even your hometown—with one of the coolest features, called HeyWhatsThat, which identifies landmarks you can see from your location—like the names of nearby mountains and overhead constellations.
AOL Instant Messenger (AIM)
Send and receive instant messages over Wi-Fi, EDGE, or 3G networks, and manage your AIM buddy list right on your device with the AIM iPhone app.
PayPal
Send money from your iPhone or iPod touch to anyone—like your dinner companion when you're splitting the bill—with the PayPal app. You've been able to send money via SMS using PayPal for some time now, but the app makes it even easier—it keeps you from having to remember the text message format.
