Create Packed Indexes with MySQL
I am pretty much sure that you are aware of indexes which we are creating on database fields. Indexes are very useful to make your query search faster and improve the site performance. But the fact is that Indexes which we are creating on database tables also require some additional space on your hard disk and if you have not properly created these indexes than some t...

Language Complexity?
Some languages are complex, others are simple … right? C++ versus just about anything else is a good example here. But, it begs the question: what makes a language complex? So, I’ve just been reading Bruce Eckel’s Artima article on Scala. It’s actually a nice article, and I enjoyed it. But, one thing bugged me — and, it’s nicely summarised in this quote: But you can see from the code above that learning Scala should be a lot eas...

Maintain multiple versions of Go in one single environment
In a development environment, there might be multiple projects going on at the same time and they may require different development environments with different versions of build tool. In many programming languages, it is possible to have multiple versions of different build tool or development tool on a single environment. For example, there can be multiple JDKs, multiple versions of Ruby using RVM. For GoLang, there is a similar tool called GVM which can also be used to maintain multiple versio...

Some frequently used ES6 code snippets
Below are a list of ES6 code snippets which are used frequently. Hope that it will be helpful. 1. Shuffle array elements let arr = [67, true, false, '55'] arr = arr.sort(() => 0.5 - Math.random()) console.log(arr) // [ '55', 67, false, true ] 2. Remove characters which are not numbers const str = 'xieyezi 23213 is 95994 so hansome 223333' const numbers = str.replace(/\D/g, '') console.log(numbers) // 2321395994223333 3. Reverse sequence or words const sentence = 'xieyezi js so handsome, lol.'...

Secure Your Go Code With Vulnerability Check Tool
Security vulnerabilities exist in any language and any code, some are written by ourselves, but more are from the upstream dependencies, even the underlying Linux. We have discussed the security protection methods for Go and Kubernetes Image in Path to a Perfect Go Dockerfile and Image Vulnerability Scanning for Optimal Kubernetes Security, in which the security scanning was performed based on generic. As the Go community grows, more and more open-source packages have caused ...

The Book That Every Programmer Should Read
No, it’s not Knuth’s “The Art of Programmingâ€. I’m talking about quite an easy-to-read (compared to TAoP) book, which, in fact, does not require any engineering or mathematical background from the reader.I am talking about C. Petzold’s “CODEâ€. It is a truly remarkable book about how computers work. Let me explain why I think this book is so awesome.The book starts from the very beginning, from explaining what code is, bringi...

High performance web apps with C++
It is Christmas over here, and it is time of giving. So I decided to give something back to the community. I guess this is as old as web programming itself. Trying to create C++ web framework. If you search on the web, you can find dozen of guys that had exactly the same idea. I am not different. For one of the previous projects(discontinued now) I created simple web framework in C++. If you like to hack in C++, here it is. Code is provided as-is, as part of larger application. You can ex...

SkipList in Go
Algorithmic thinking is the must-have in the coding world, so I have been keeping the routine of algorithm practice every week, consolidating my knowledge of data structures on one hand, and improving my coding skills as well. A difficult one happened to be stuck in my mind- Implement SkipList with Go, which took me quite a weekend. Below is the front-line report of how I finally got the hang of it. First, from its concept. Wiki has explained it well. a skip list is a probab...
