  Why accessing Java HashMap may cause infinite loop in concurrent environment

HashMap in Java is frequently used to handle key/value pairs. But it is not a good candidate to be used in concurrent environment where ConcurrentHashMap should be used instead. If used in concurrent environment, it may cause lots of unexpected behavior even including make the program getting into an infinite loop situation. To understand how this can happen, let's first discuss how HaspMap works internally. In this post we will use implementation of HashMap before Java 8 as example, Java 8 prov...

  The Death of .NET and the Power of Perception

One of my long-standing issues with Microsoft is its inability to control the perceptions surrounding its own products. One of the biggest examples was during the Windows Vista years when, even after the product had been fully patched and worked fine, Apple continued to do a better job to define the image of Windows (compilation of ads here) than Microsoft did, costing Microsoft billions in lost revenue for the millions it saved on a strong advertising campaign. The firm has a history of being p...

  Advanced event registration models

On this page I explain the two advanced event registration models: W3C’s and Microsoft’s. Since neither is cross–browser supported, their use is, for the moment, deprecated. W3C and Microsoft have both developed their own event registration model to replace Netscape’s traditional model. Though I’m not impressed by the Microsoft model, W3C’s is very good, except for one crucial vagueness. Unfortunately few browsers support it at the moment. W3C W3Câ...

  Example of less is more

Less is more is a very important design principle. It is as important as the 80:20 principle. It means that which is less complicated is often better understood and more appreciated than what is more complicated; simplicity is preferable to complexity; brevity in communication is more effective than verbosity. Next we will use an animated image to describe what is less is more. The popularity of flat design in web application design also proves the importance of less is more. Many famous compan...

  Windows Security Improvements

Traenk is still upset by his recent dive into Windows security.  So much more was promised when the merger of Windows 9x and NT lines was announced, so long ago. I honestly expected better.Long ago, Microsoft announced that it would merge the then NT and Windows 9x lines of products.  Wow!  That means a file access control system, logging, different accounts and filespaces for accounts!  Finally!  We would have a secure version of Windows for our homes!And we do hav...
