  Productivity is just work

The other day, I wrote a post declaring that I will no longer try to increase my productivity. This doesn't mean I won't read productivity blogs, and tweak things, and manage my "system". It means I no longer think about any of that stuff as having anything to do with productivity. Productivity is what happens when you're doing work. Enhancing your productivity is what happens when you do a lot of work, for long enough to get better at it. Look, throw all your stuff in Dropbox, live yo...

  Haskell’s effect on my C++: exploit the type system

Like most programmers, I was attracted to Scheme by the promise that it would make me a better programmer. I came to appreciate the functional style, but swapped to Haskell, a more developed language with a rapidly developing standard library. Unfortunately, for me, Haskell can’t yet replace C++ on a day to day basis, so I reluctantly spend my days tapping away at C++. So, were the promises true? has functional programming made me a better programmer? Better is a tough question,...

  C++ 11 Memory Management

Enterprise development and networking specialist Stephen B. Morris illustrates how to handle a classic C/C++ problem by using the new features in C++ 11 in conjunction with more established techniques.Memory management has always been one of the most error-prone areas of C++. The same is true of C. One of the strengths of managed languages, such as Java and C#, is their support for automatic garbage collection. Garbage collection still isn't a feature of C++ 11, so we must still be caref...

  Practice of using spinlock instead of mutex

Spinlock and mutex are two important concepts in multithreading programs. They are used to lock some shared resource to prevent concurrent access which may affect data consistency. But they do have differences, what are the differences? when should we use spinlock instead of mutex? The Theory In theory, when a thread tries to lock a mutex and it does not succeed, because the mutex is already locked, it will go to sleep, immediately allowing another thread to run. It will continue to sleep until...

  Books for entry level C programmers

In computing, C is a general-purpose programming language initially developed by Dennis Ritchie between 1969 and 1973 at Bell Labs Its design provides constructs that map efficiently to typical machine instructions, and therefore it found lasting use in applications that had formerly been coded in assembly language, most notably system software like the Unix computer operating system.To learn C, we need to read many C books and have many practices. Here we summarize a list of C books which may h...

  Different module types in Java 9

Java 9 is going to introduce a disruptive change to the Java platform -- Module System. The module system will change how Java applications work in the future. It's like changing the foundation of a house without impacting the house functionality and its top level structure. This obviously is a big challenge for the whole Java community.  To bring as little pain as possible to migrate existing applications to Java 9 without refactoring the whole application, Java 9 will introduce a few diff...

  My frequently used Linux commands

In our day to day work. We may have many chances working on Linux/Unix systems. There are many things we may need to do, checking logs, navigating in directories, creating file or installing software. We may use many commands to complete the work, such as ls, mkdir, cd etc. Below are my frequently used Linux commands or programs recently: pwd : print working directory, sometimes I need to check which working directory I am in in order to know where to go next. ls : List current directory files,...

  What is cache penetration, cache breakdown and cache avalanche?

When designing and developing highly available system, cache is an very important consideration. It is useful to cache some frequently accessed data so that they can be accessed quickly and also cache can protect the downstream system like DB from being hit too often.  To provide better cache design in large systems, some problems may need to be considered first. In this post, we will talk about some frequently discussed cache problems and mitigation plans. Cache penetration Cache penetrati...

  The Web Is Wrong

The Analogies Are Wrong Originally, web pages were static documents, and web browsers were static document viewers; there was text, some formatting, and images—if you could pay for the bandwidth to serve them. Hyperlinks were the really big thing, because they were the main point of user interaction—but what a powerful thing they were, and still are. Then along came CGI and Java, and the web was transformed: all of a sudden, a web browser became a way to serve interactive co...

  Guide to Implement an SSH Client Using Golang

SSH, short for Secure Shell, is a network protocol used for securely remote logging into other computers on a network. I believe most backend developers are familiar with SSH. Common shell tools used for logging into servers, such as Xshell, SecureCRT, and iTerm2, are all based on the SSH protocol. In Golang, the crypto/ssh package provides functionality for implementing an SSH client. In this article, we will explain in detail how to implement an SSH client using Golang. Creating SSH Client Con...
