  What's Wrong with the For Loop

Closures in Java are a hot topic of late. A few really smart people are drafting a proposal to add closures to a future version of the language. However, the proposed syntax and the linguistic addition are getting a lot of push back from many Java programmers. Today, Elliotte Rusty Harold posted his doubts about the merits of closures in Java. Specifically, he asks "Why Hate the for Loop?": I don’t know what it is some people have against for loops that they’re so eager to...

  You know what UTF-8 is when you see it?

When we are coding we may often see some encoding specifications in our source codes such as UTF-8,GB2312. Do you know what these encoding mean and why we need them? In this post, Julián Solórzano will introduce the most widely used encoding specification around the world accomodating all different character sets in the world. UTF-8 is a method for encoding Unicode characters using 8-bit sequences. Unicode is a standard for representing a great variety of characters from many ...

  Obviously Correct

What do automatic memory management, static types and purity have in common? They are methods which take advantage of the fact that we can make programs obviously correct (for some partial definition of correctness) upon visual inspection. Code using automatic memory management is obviously correct for a class of memory bugs. Code using static types is obviously correct for a class of type bugs. Code using purity (no mutable references or side effects) isobviously c...

  Paradigms of Iteration in JavaScript

One of the joys of programming is that no matter how simple a problem may seem there are always tons of ways to solve it. It can be good practice to go back and revisit fundamentals by solving simple problems with as many implementations as you can think of. In this post we'll explore approaches to basic iteration in JavaScript. This style of exercise is a good interviewing technique, too, because it's open ended and leads to good discussions. The focus isn't a tricky, wacky problem you're...

  Web Vs. Native: Which Is the Better Type of Mobile App?

An average US adult spends 3 hours and 15 minutes on their smartphone every day. This means that launching an app of your own is a great business opportunity. However, you need to decide whether you want to develop a native or a web app. The difference boils down to the fact that web apps run through a mobile browser and native apps are full-fledged programs. Each option has its pros and cons and can be successful under some circumstances. To make the right decision, you need to understand ...

  C Preprocessor Hell

Lisp programmers should stop reading right now because they'll likely suffer severe injury of the jaw muscles as they laugh themselves silly at how hard it is to do some things in C. The C language has a pre-processor (typically called cpp) that is both infuriating and powerful. How powerful is usually best described as 'just too little' and it has happened more than once that I found myself almost - but not quite - able to do what I wanted to do. The frustration can run very deep at ti...

  A Solution to CPU-intensive Tasks in IO Loops

Back in October 2011, Ted Dziuba infamously said that Node.js is Cancer.  A provocative title to a provocative article.  The only thing it didn’t really provoke in the commentary was much thought ;)  Zing. My interpretation of the article is that Ted holds up the classic blocking-IO process-per-request (or  thread per request; same difference) model as superior.  Yet we all remember where the blocking-IO forking model got Apache in the early days.  ...

  Java Then, Java Now - Looking at the evolution of Java from EE7 to EE9

Java, the programming language developed at Sun Microsystems in the 90s and later acquired by Oracle, is the most common programming environment used today, by developers across the globe. With the diversification of applicability that accompanied the technological boom, Java updates now come as Standard Editions (SE), Enterprise Edition (EE) and Micro Edition (ME). The Java SE contains the core programming logic and platform, used for relatively smaller-scale tasks and academic purposes. Java E...

  Some thoughts about microservice adoption

Nowadays microservice is very popular among companies with the increasing complexity of systems. The goal is to make each microservice to handle one specific job and handle it well. This normally would provide the benefit of maintaining the service easily and isolating errors and making the service more reliable and scalable. The benefits of adopting microservice are obvious. Maintainability. Decouple functions so that each function can be maintained separately which reduces the risk of issue ...

  Some lovely software design quotes

  Every time when I read technical books, I like reading the quote of a famous person at the start of a chapter(if any), usually they are very interesting. Here is a collection of famous quotes. Life’s too short to build something nobody wants – Ash Maurya, Running Lean author Give someone a program, you frustrate them for a day; teach them how to program, you frustrate them for a lifetime. – David Leinweber There are two ways of constructing a software design: One way is...
