  The internals of slice in GoLang

There are 3 components of slice:a) Pointer: Points to the start position of slice in the underlying array;b) length (type is int): the number of the valid elements of the slice;b) capacity (type is int): the total number of slots of the slice. Check the following code: package main import ( "fmt" "unsafe" ) func main() { var s1 []int fmt.Println(unsafe.Sizeof(s1)) } The result is 24 on my 64-bit system (The pointer and int both occupy 8 bytes). In the next example, I will use gdb to poke t...

  Breaking Barriers: How 3D Printing is Democratizing Product Development

Innovation has always been the cornerstone of progress, driving societies forward and shaping our future. However, for many years, the realm of product development and manufacturing was largely restricted to big corporations with hefty budgets and access to specialized resources. This created a barrier for individuals and small businesses aspiring to bring their ideas to life.

  HeartBleed: Should C be blamed for the HeartBleed bug?

There is a discussion about the security of applications written in C on Hacker News recently after the report of HeartBleed bug in OpenSSL. In this discussion, some people are saying that the applications written in C are unsafe. It seems all or most of the faults should be laid on C. I think this is biased. The language itself should not be blamed.Safety is a relative term for programming languages. No language is absolutely safe. We claim some languages like Java and C# are safer than C/C++ b...

  You should publish your contributions of Open Source, even it’s not required

Although many Open Source projects don’t require you publish the modifications of them, I still propose you should make the changes open. The reasons are as following: (1) For other people: the out-of-box Open Source projects save your time and money, and you get benefit from them. You should not only take, but also need to give! Only if everyone shares his code, document, or whatever related, the Open Source projects can grow up healthy. (2) For yourself: You release your code can actuall...

  What Makes A Great Programmer?

I remember it like it was yesterday. It was the year 2000, Dr. Pargas was standing at the front of our data structures class talking about some data structure-y topic while an SSH session was projected on the wall in front of us. Someone asked a question, and he said something along the lines of "Well, if you want to be a real computer scientist you need to start using vi". I think he was smiling as he said it, and in hindsight his statement wasn't even slightly true, but being young and ...

  Clean Code Versus Great Code

I've had some interesting discussions with other developers about writing code recently. I often have the impression that some developers put too much emphasis on clean code. Don't get me wrong, i strive for clean code as well, and have written about its importance quite a lot in the past couple of years. But when i'm coding, clean code is my secondary goal and it could never take the place of my primary goal: making it work. And preferably, i want to make it work great. A lot of people love t...
