  Tricks with Direct Memory Access in Java

Java was initially designed as a safe managed environment. Nevertheless, Java HotSpot VM contains a “backdoor” that provides a number of low-level operations to manipulate memory and threads directly. This backdoor – sun.misc.Unsafe â€“ is widely used by JDK itself in packages like java.nio or java.util.concurrent. It is hard to imagine a Java developer that uses this backdoor in any regular development because this API is extremely dangerous...

  Never create Ruby strings longer than 23 characters

Looking at things through a microscopesometimes leads to surprising discoveries Obviously this is an utterly preposterous statement: it’s hard to think of a more ridiculous and esoteric coding requirement. I can just imagine all sorts of amusing conversations with designers and business sponsors: “No… the size of this <input> field should be 23… 24 is just too long!” Or: “We need to explain to users that their subject lines should be les...

  GCC is compiled with C++ compiler

On 15 Aug, 2012, GCC merged a patch--Merge from cxx-conversion branch . This means GCC will be compiled with C++ compiler in the future, it also means that GCC will be implemented using C++. You may have following two puzzles: Why does GCC turn to C++? Without C++ compiler, how can we compile C++ codes? Why using C++? In GNU's C++ Conversion, we can find this description in the background section: Whether we use C or C++, we need to try to ensure that interfaces are easy to understan...

  CRM Approach - A Well Planed Business Strategy Not a Mere Technology

Customer relationship management (CRM) has transitioned and evolved over the last few years.  Its adoption is powered by the rapid growth and popularity of SaaS tools. Too many companies have adopted CRM in order to cater to customers in a better manner and hence build loyalty. However, often implementing CRM does not yield the results as expected.

  How DNS lookup works

When accessing a website, a domain name would be needed normally. To get to the actual web server, the domain name must be mapped to an actual IP address and the IP address will be used to reach the web server. The process of finding the IP address from a domain name is called DNS lookup.  How does DNS lookup work? There are tons of domain name and IP address around the world, there must be some well-designed architecture to support fast lookup. This post will explain how this works. DNS Se...

  Why Does Work Start At 9 A.M.?

I prefer to come into work a little earlier before our 9 a.m. start time in order to leave before 5 p.m. My boss has no problem with my hours, though an older female colleague apparently does. She regularly tells me that this “special” work schedule is damaging my career trajectory and conveys to others that I am a diva. To that I reply, according to whom? There are many workplace assumptions that employees accept without question. Why does the traditional work day start at 9 a...

  Go channel explained

In Go, a channel is a type of concurrent data structure that allows two or more goroutines (Go's term for lightweight threads) to communicate with each other. Channels provide a way for goroutines to send and receive values, and they are an essential part of Go's concurrency model. Here's a simple example that demonstrates how to use channels in Go: package main import ( "fmt" ) func main() { // Create a new channel with the `make` function ch := make(chan int) // Start a new ...
