The best Cydia apps for iphone exp2


BiteSMS, Messages+

BiteSMS lets you quick-reply to messages from anywhere in iOS
Two apps, with one goal: to enhance iOS messaging. Both BiteSMS and Messages+ let you quick-reply to a text without leaving the app you're in, or assign a gesture to compose a new message from anywhere in iOS.
BiteSMS has been around longer, and offers theming and tons of customization. Messages+ is more streamlined, and integrated into the stock Messages app. It's worth checking out both to find your favorite.

SwipeSelection

SwipeSelection makes editing text much easier
Typing on an iPad isn't ideal, but it's tolerable. Editing text, though, is a pain. SwipeSelection improves it dramatically: slide across the keyboard to move the cursor, and slide from either shift key to select text.

Merge

Merge organizes your messaging threads by person, rather than email address or phone numbe...
Tired of having multiple iMessage threads for the same person? Merge combines all of your conversations for each contact into a single thread.
It's another Cydia app that Apple would be wise to emulate.

Auxo

Auxo is one of the best approaches to multitasking we've ever seen
Many jailbreak developers have tried to reinvent iOS multitasking, but Auxo stands out as the one Apple is most likely to copy.
Auxo's killer feature is its multitasking cards, which show live previews of open apps. But it's the tiny details (settings toggles, multitouch swipe-to-dismiss, expanded music controls) that make it an all-time great.

Zephyr

Gesture lets you replace your home button with intuitive gestures
Tired of always pressing and double-tapping your iPhone’s home button? Zephyr will replace it with a series of intuitive gestures.
After installing Zephyr, a short swipe up from the bottom of the screen will bring up the multitasking switcher. A longer swipe up will close your current app. Swipe from the left to return to your most recent app.

TetherMe

TetherMe activates iOS' native hotspot without subscribing to your carrier's tethering pla...
Fed up with your wireless carrier's tethering policy? TetherMe lets you activate your iPhone's personal hotspot without adding a separate plan.
TetherMe claims to be undetectable by carriers, but use at your own risk. No tethering app is guaranteed to be 100 percent stealthy, and using it likely violates your wireless agreement.

Jailbreak an iPhone


Apple iPhone



jailbreaking your iPhone means freeing it from the limitations imposed on it by your carrier, whether that's AT&T or Verizon, and Apple. You install a software application on your computer, and then transfer it to your iPhone, where it "breaks open" the iPhone’s file system to allow you to modify it.

Why Would I Want to Jailbreak My Phone?

It lets you do everything from customizing the look of your iPhone to installing third-party applications (such as titles that are not authorized and available in the App Store) and customized ringtones on it. Depending on how far you're willing to go, you can do even more than that: Jailbreaking even lets you to unlock your phone so you can use it with a carrier other than the one from which you purchased it.

Can I Fix My iPhone if Something Goes Wrong?

Maybe. Some users have reported that they were able to connect a malfunctioning iPhone to iTunes and restore it to its original settings, which resolved the problem. Not all users have had this experience, though, and you certainly can't count on AT&T, Verizon, or Apple to provide you with tech support once you've taken this unauthorized step.

so how can i jailbreak my iPhone?

Leonhard Euler: Mathematician's 306th birthday


File:Leonhard Euler 2.jpg

Euler is one of the most famous mathematicians of all time and he contributed a huge amount to maths. He is most famous for Euler's equation which unites 5 of the fundamental numbers in maths: e, i, pi, 1 and 0. It looks like this: 
e^(i*pi)+1=0










Leonhard Euler was one of the greatest mathematicians of all time. His numerous works (over 900 publications) in many areas had a decisive influence on the development of mathematics, an influence that is felt to this day.

Euler was born in Switzerland, in the town of Basel, on the 15th of April 1707, in the family of a pastor. At that time, Basel was one of the main centres of mathematics in Europe. At the age of 7, Euler started school while his father hired a private mathematics tutor for him. At 13, Euler was already attending lectures at the local university, and in 1723 gained his masters degree, with a dissertation comparing the natural philosophy systems of Newton and Descartes. On his father's wishes, Euler furthered his education by enrolling in the theological faculty, but devoted all his spare time to studying mathematics.

He wrote two articles on reverse trajectory which were highly valued by his teacher Bernoulli. In 1727 Euler applied for a position as physics professor at Basel university, but was turned down.

At this time a new centre of science had appeared in Europe - the Petersburg Academy of Sciences. As Russia had few scientists of its own, many foreigners were invited to work at this centre - among them Euler. On the 24th of May 1727 Euler arrived in Petersburg.

His great talents were soon recognised. Among the areas he worked in include his theory of the production of the human voice, the theory of sound and music, the mechanics of vision, and his work on telescopic and microscopic perception. On the basis of this last work, not published until 1779, the construction of telescopes and microscopes was made possible.

In his study of colour effects, Euler hoped to make use of the observation of the conjunction of Venus and the moon, due to take place on the 8th of September 1729. However, no such effects were observed during this conjunction, and Euler was forced to wait for the eclipse of the sun which would take place in 1748. He observed this eclipse in Berlin, where he moved in 1741. Here he worked in the Berlin Academy of Sciences and was appointed as head of the Berlin Observatory, and was also tutor to the nieces of King Frederich II of Prussia.
Observations of the eclipse of the sun made by scientists of the day led them to believe that the moon did not contain sufficient atmosphere to provide the effects of diffraction or refraction. Only Euler was able to detect the moon's atmosphere. And in 1761, when Venus passed over the face of the sun, he detected the atmosphere of Venus.
Euler's works were not devoted solely to the natural sciences. A true renaissance man, he also involved himself in the philosophical debates of the day, and triumphantly declared himself a firm believer in the freedom of the will. Such views won him few friends in Germany, and the book in which he thus expressed himself was published for the first time in Russia, where Euler returned in 1766. Here he found many who agreed with his views, among them enemies of the views of Leibnitz and Voltaire.

In 1763 Catherine II came to the throne. She carried out reforms in the Academy of Sciences and aimed to make it a more prestigious institution. When Euler returned to Petersburg with his two elder sons they were given a two-storey house on the banks of the Neva and Euler given a position at the head of the Academy of Sciences.
At the time of his return to Petersburg Euler had already reconsidered his views on the atmosphere of planets. The work of Lomonosov and Bernoulli in this field led him to conclude that the atmosphere on the Earth and on other planets must be considerably more transparent than he had thought. Euler took a very active role in the observation of the movement of Venus across the face of the sun, despite the fact that at this time he was nearly blind. He had already lost one eye in the course of an experiment on light diffraction in 1738, and an eye disease and botched operation in 1771 led to an almost total loss of vision.

This did not, however, stop Euler's creative output. Until his death in 1783, the Academy was presented with over 500 of his works. The Academy continued to publish them for another half century after the death of the great scientist. To this day, his theories are studied and taught, and his incredibly diverse works make him one of the founding fathers of modern science.

how we can see color


How the Eye Sees Color

alt
Color originates in light. Sunlight, as we perceive it, is colorless. In reality, a rainbow is testimony to the fact that all the colors of the spectrum are present in white light. As illustrated in the diagram below, light goes from the source (the sun) to the object (the apple), and finally to the detector (the eye and brain).

 how the eye sees color
1. All the "invisible" colors of sunlight shine on the apple.

2. The surface of a red apple absorbs all the colored light rays, except for those corresponding to red, and reflects this color to the human eye.

3. The eye receives the reflected red light and sends a message to the brain.
 
The most technically accurate definition of color is:
"Color is the visual effect that is caused by the spectral composition of the light emitted, transmitted, or reflected by objects."
