Why developer-friendliness is central to API design
Today, APIs play a bigger role in software development than ever before. The evolution of computing has been dominated by ever-increasing levels of abstraction; the use of higher-level languages, of course, but also the development of platforms, libraries, and frameworks. Professor Douglass C. Smith claims the progression of this second category far outpaced the development of programming languages. Developers are also noticing that difficulty has shifted from designing algorithms a...

10 Points about Java heap memory
When I started java programming I didn't know what is java heap or what is heap space in Java, I was even not aware of where does object in Java gets created, it’s when I started doing professional programming I came across error java.lang.outofmemoryerror then I realized What is Heap in Java or Java Heap Space. Its happens with most of programmer because learning language is easy but learning basics is difficult since there is no formal process which can teach you every basics of pro...

HTML above flash (transparency + z-index)
We have faced this problem many of the times. When we want to display some message on top of all layers on a page or use some feature like jQuery light boxes. Normally the flash file continues to shine through the page. No matter what you do with layering the dom elements using z-index.See the layering flash content problem definition here.Before this, people used to dodge this issue with some fixes like hiding the flash area completely and then showing a static image of...

Don’t Call Yourself A Programmer, And Other Career Advice
If there was one course I could add to every engineering education, it wouldn’t involve compilers or gates or time complexity. It would be Realities Of Your Industry 101, because we don’t teach them and this results in lots of unnecessary pain and suffering. This post aspires to be README.txt for your career as a young engineer. The goal is to make you happy, by filling in the gaps in your education regarding how the “real world†actually works. ...

Programming language choices for an IT manager
A TechRepublic reader named Aaron emailed me and posed excellent questions; here’s an excerpt from his email:“I manage a small IT department and all my skills are self-taught. At times I struggle with complex business initiatives and I believe if I had some programming skills I would be more adept at handling the initiatives. Can you recommend a programming language? Is formal education the best path or have you found that programming can be self-taught?â€I’m sure a lot ...

Understand JavaScript prototype
For an front end programming language like JavaScript, if we want to understand its OOP feature, we need to understand its objects, prototype chain, execution context, closure and this keyword in deep. If you have a good understanding on these concepts, you should be confident that you can handle this language well. The inheritance in JavaScript is not class inheritance like Java, but it adopts another mechanism-- prototype inheritance. The key to prototype inheritance is the prototype chain mec...

JavaScript efficiency catch up
JavaScript is a very flexible language, we can write JavaScript code freely with various styles, different kinds of codes will have different execution efficiency. Here we summarize some tips we get from our development. Efficiency of JavaScript itself JavaScript has execution context chain, closures, prototype inheritance, eval etc. It brings us some magic features, but it also introduces the performance issue, if we don't use them properly, it will affect the codes execution efficiency. 1. Glo...

All Programming is Web Programming
Michael Braude decries the popularity of web programming:The reason most people want to program for the web is that they're not smart enough to do anything else. They don't understand compilers, concurrency, 3D or class inheritance. They haven't got a clue why I'd use an interface or an abstract class. They don't understand: virtual methods, pointers, references, garbage collection, finalizers, pass-by-reference vs. pass-by-value, virtual C++ destructors, or the differences between C# struc...

When and How to Use the Go Channel
Go’s concise structure and powerful native library enable us to hit the ground running easily. It is more efficient than Java or Python when implementing the same functions, especially its concurrent programming, which is very handy and widely admired due to its goroutine and channel. goroutine and channel has much to dig into, and let’s start with channel, which I used to consider narrowly as a message queue to transfer data between gorouti...
Python – parallelizing CPU-bound tasks with multiprocessing
In a previous post on Python threads, I briefly mentioned that threads are unsuitable for CPU-bound tasks, and multiprocessing should be used instead. Here I want to demonstrate this with benchmark numbers, also showing that creating multiple processes in Python is just as simple as creating multiple threads. First, let’s pick a simple computation to use for the benchmarking. I don’t want it to be completely artificial, so I’ll use a dumbed-down version of factorization...
