  Difference between sans-serif and serif font


When we design website, we will often need to choose which font to use while displaying contents on the page. Basically what's the criteria for the choice? There are two big families of fonts : sans-serif and serif. We need to first understand what the difference is between these two. The word sans is from French, the meaning of it is without. So the difference between sans-serif and serif is serif font will have lines in all ends of the character while sans-serif fonts don't have. Some examples...

  Java API vs Framework


What is the difference between a Java Library and a framework? The two concepts are essentially important for a Java developer. The most important difference between a library and a framework is Inversion of Control. It means that when you call a library you are in control. But with a framework, the control is inverted: the framework calls you. (This is called the Hollywood Principle: Don’t call Us, We’ll call You.) This is pretty much the definition of a framework. Basically, all the...

  What is Asian UI design like from a Western point of view?


From a western point view, Asian UI designs are usually quite dense and compact. People in Asia are think more in detail when they start design something. They think these designs have following characteristics Dense tightly packed text Tiny low-quality images More columns than you can count Bright clashing colours and flashing banners Overuse of outdated technologies like Flash While the Western design is much simpler. They are treating the design as a whole, so usually we will see some quite...

  The Obvious, the Easy, and the Possible


Much of the tension in product development and interface design comes from trying to balance the obvious, the easy, and the possible. Figuring out which things go in which bucket is critical to fully understanding how to make something useful. Shouldn’t everything be obvious? Unless you’re making a product that just does one thing – like a paperclip, for example – everything won’t be obvious. You have to make tough calls about what needs to be obvious, what should be easy, and...

  Difference between Beijing and Silicon Valley on innovation


The fundamental difference between Beijing and Silicon Valley is not the sky color, but the fact that on one side the young people are talking about buying a new house, a new car and getting married, while on the other side young people are talking about how to change the world. Now and then we can read from the newspaper or the Internet that a Silicon Valley company is valued over 1 billion US dollars. Also we can see many famous US IT brands on the Internet such as Google, Facebook,Twitter, Am...

  ConcurrentHashMap vs Collections.synchronizedMap()


ConcurrentHashMap and Collections.synchronizedMap() both provide thread-safe operations of collections of data. They are used in multithreaded programs to provide both thread safety and performance improvements. In many cases, we can use either of them. But the realization of thread safety is different for these two implementations. ConcurrentHashMap will create an HashEntry[] array internally to store the elements passed in from a Map, while Collections.synchronizedMap() will return a Synchroni...

  Multithreading interview questions in Java


Multithreading as a widespread programming and execution model allows multiple threads to exist within the context of a single process. These threads share the process' resources but are able to execute independently. The threaded programming model provides developers with a useful abstraction of concurrent execution. However, perhaps the most interesting application of the technology is when it is applied to a single process to enable parallel execution on a multiprocessor system.Many programme...

  Do we need other languages other than C and C++?


There were hundreds of or thousands of programming languages created since the invention of computer. All these languages have the same target which is to make the computer do what we want it do. So we may find that many languages have the same functions, i.e, one task can be completed by one language can be completed by another language as well. Now we may wonder why we need so many different languages. Can we just have C or C++ since they provide the best performance we need. The answer obviou...
