  Implementing DESede/ECB/NoPadding cipher algorithm in GoLang

By default, GoLang doesn't provide the ECB mode cipher for DESede though there is CBC mode provided. In cases we need to encrypt/decrypt data with ECB mode, we need to implement those by ourselves. This mode is frequently used when encrypting/decrypting PIN block which is small block data less than 16 bytes. In this post, we will introduce how to implement the DESede/ECB/NoPadding algorithm in GoLang by using the existing cipher support. Here we will not cover how DESede works in detail, instead...

  Custom C++ exception class creation

In standard C++, we can use try catch to catch and exception when something goes wrong. These are some built in exception support in C++. By including the #include , we can now catch exceptions in C++ programs. This actually helps us on debugging our code and reduce the maintenance work.However sometimes if we want to create our own custom exception class. What should we do?We should include the #include line and then extend the exception class and implement some methods as you like. The genera...

  Why to opt for Hadoop?

Hadoop is a open source that stores and processes big data. The framework is written in Java for distributed processing and distributed storage of very large data. Hadoop is Scalable. It is a scalable platform because it stores and distributed large amount of data sets to hundreds and thousands of servers that operate in parallel. Traditional database systems cannot process large amount of data. But, hadoop enable business to run applications involving thousands of Terabyte data. Hadoop is ...

  Writing great JavaScript

I probably could have named this post something like “Writing clean, validating and portable JavaScript”, but that would be no where near as catchy. The problem with “great” is it means different things to different people. I am going to show you my idea of great which may differ from many developers views, but I hope it helps someone improve their code. So what’s the point in this, why can’t you just carry on writing JavaScript as you have been for a...

  Web programs written in C++ are no big deal

I had an interesting conversation with a friend the other day. She wanted to try putting together a weekend "hackathon" just to see what we could build. It would be one of those fun things where we just start tinkering and see what comes out of it. Somehow, this conversation got to the topic of libraries, programming languages, and frameworks. Then it got a little weird. I guess the current "shiny" thing is still more-or-less Ruby, and particularly when used with Rails. Oh, I suppo...

  4 asynchronous programming methods in JavaScript

You may know the execution environment of JavaScript is single threaded. The so called single thread means only one task can be running at any time, if there are many tasks, they need to be in a queue and wait for the previous task to be completed. The advantage of this mode is it's easy to implement and the execution environment is relative simple; the disadvantage is that if one task takes long time, the tasks following it must wait in the queue and this will delay other tasks consequently. Th...

  The First Bite on etcd Code

Etcd, one of the crucial components of Kubernetes. If APIServer is the heart, then etcd is the blood vessel that sends the end state of Kubernetes resources to various “organs”, providing high-speed, stable storage, and supporting APIServer’s high load performance. What if the etcd is not working properly? Just the condition as someone has a vascular disease. The deeper you know about them, the better diagnose you can make when issues occur. from unspl...

  How One Missing `var` Ruined our Launch

Well, that was a veritable shitstorm (sorry for the language).  Long story short, MelonCard was featured today on TechCrunch (along with other500Startups companies, also on VentureBeat, Forbes, …) and everything broke all at once.  Every. little. thing.  We had rolled out a huge change to MelonCard over the last few days to make our site a seamless “everything just updates” look-good / feel-good product using NodeJS lo...
