  Why is Great Design so Hard?

I want to take a slight detour from usable privacy and security and discuss issues of design. I was recently at the Microsoft Faculty Summit, an annual event where Microsoft discusses some of the big issues and directions they are headed. In one of the talks, a designer at Microsoft mentioned two data points I've informally heard before but had never confirmed. First, the ratio of developers to user interface designers at Microsoft was 50:1. Second, this ratio was better than any other comp...

  JSON unmarshal in GoLang

In almost all mainstream programming languages, there is either built-in or third-party library to support parse JSON data because it is so popular for organizing and transferring data among different services. In GoLang, the built in json package also provides functions for marshalling and unmarshalling JSON data. Marshalling GoLang struct to a JSON string is relatively simple, just need to call json.Marshal(), it's a bit complicated to unmarshal an arbitrary JSON string into a GoLang struct ob...

  What can select do in GoLang

In Go language, select is a keyword used to listen to and perform IO operations related to channels. With the select statement, we can simultaneously listen to multiple channels and perform corresponding operations when any of the channels are ready. This article will summarize the common uses of the select statement and provide some considerations when using it. Basic syntax The basic syntax of the select statement is as follows: select { case <-channel1: // when channel1 has data to ...

  Let's talk about JSON.stringify()

JSON has been used in lots of places to exchange data among different services/systems. Nowadays all mainstream programming languages have built-in library support of JSON data parse and stringify. In this post, let's talk about JSON.stringify() in JavaScript. Let's first take a small example of Object conversion handling. There is a requirement to convert below object const todayILearn = { _id: 1, content: '今天学习 JSON.stringify()，我很开心！', ...

  Useful git commands in daily work

In a developer's daily work, it is frequent to see lots of commits made. It would be a headache if one cannot use git commands well especially when in cases where some fixes need to be made on existing branches. There are some frequently used command such as git pull, git merge and git push. Apart from these, there are some other practical commands which may be useful for real use cases. This post will try to list some of them. git grep  It will lists all files containing the searched keywo...

  We need a programming language for the rest of us

Recently I took on the enormous task of learning Objective-C from the bottom up and I was struck by something I couldn’t shake: this is too hard. An experienced developer might scoff at me for saying that, but it’s true. I’ll be honest about my education, Calculus II was the most math I ever took, I have an advanced degree from Berkeley in Journalism. I am a proficient HTML/CSS developer and can glue enough javascript together to solve almost any problem that has presen...

  Why using + to concatenate string in Java loop is not a good option

String concatenation is a common operation in Java programming. It is to concatenate multiple strings into a single string. Java provides a String class which is an immutable class which means the object cannot be mutated once instantiated. Once a String object is instantiated, its properties cannot be changed anymore, so when concatenating strings, it's actually create a new String instance to store the concatenated string values. For example, below is a simple string concatenation example. Str...

  Why every programmer should learn Python or Ruby

If you are a student, you probably know C, C++ and Java. A few know VB, or C# / .NET. At some point you’ve probably built some web pages, so you know HTML, CSS and maybe JavaScript. By and large, it is difficult to find students who have any exposure to languages beyond this. And this is a shame because there are a number of programming languages out there which will make you a better programmer. In this article, we give some reasons why you must learn Python or Ruby2. Compared to C...

  The Go Programming Language Turns Two

Two years ago a small team at Google went public with their fledgling project - the Go Programming Language. They presented a language spec, two compilers, a modest standard library, some novel tools, and plenty of accurate (albeit succinct) documentation. They watched with excitement as programmers around the world began to play with Go. The team continued to iterate and improve on what they had built, and were gradually joined by dozens - and then hundreds - of programmers from the open source...

  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...
