  Stream API in Java 8

Overview In this lesson on Stream API in Java, we will study how we can put Streams to use to write efficient and much more maintainable code. We will also write code with and without Streams so that we are able to compare the two versions. Before doing all this, we must know how to create a Stream and process it and that is what we will get started with. Introduction to Streams We will be starting with creating Streams. Let us get started with the Stream<T> API which enables us to play w...

  Update & Delete Kubernetes resources in one-line command

It recently troubles me that my GKE cluster is managing more and more resources and causing difficulties in maintenance, one of which involves how to delete resources properly. Next, I will explain step by step the difficulties I encountered in my work and how I finally used the combination of bash commands and kubectl to implement the edition of Kubernetes objects through one-line command. In general The following are the basic operations that almost every Kubernetes user takes. Check ðŸ‘...

  Guide to Clearing Storage Space on a Macbook

Macbooks are pretty notorious when it comes to what storage space you have available. Those few gigabytes that you have will disappear in no time if you are not careful. The whole issue becomes even more problematic for people who are not that familiar with Macbooks or have switched from another computer. And if you do not pay attention, it will not take too long before you have next to no storage space on the hard drive. Leaving only a few gigabytes of free space will significantly reduce the ...

  Write Scalable, Server-side JavaScript Applications with Node.js

If you live in the Silicon Valley area, you have already heard the buzz: Node.js is being hailed as the next big thing. It’s the silver bullet that offers scale, eases development, and can be leveraged by the vast pool of client-side JavaScript developers. So, what exactly is Node.js?Node.js is a server-side JavaScript environment that uses an asynchronous event-driven model. It is based on Google's V8 JavaScript engine plus several built-in libraries. The excitement around Node.js is tha...

  What’s Your Start-up’s “Bus Count”? 7 Myths of Entrepreneurship and Programming

Software development is a rapidly evolving field that got off to a very rocky start. Conventional wisdom for many years was that software engineering should be like other types of engineering: design carefully, specify precisely, and then just build it – exactly to spec. Just like building a bridge, right? The problem with this approach is that software is just that. Soft. It’s endlessly malleable. You can change software pretty much any time you want, and people do. A...

  The Mature Programmer

1. The Mature Programmer The mature programmer manages their own time and productivity well. The MP knows that maintenance is as much work as the initial writing and code always takes longer than you think. The MP knows that any changes to code can introduce bugs, no matter how seemingly trivial. The MP knows that premature optimization is foolish and dangerous. The MP knows that sexy coding like writing big complex systems from scratch is rarely the best way to go. The MP does not get...

  How Integers Should Work (In Systems Programming Languages)

My last post outlined some of the possibilities for integer semantics in programming languages, and asked which option was correct. This post contains my answers. Just to be clear: I want practical solutions, but I’m not very interested by historical issues or backwards compatibility with any existing language, and particularly not with C and C++. We’ll start with: Premise 1: Operations on default integer types return the mathematically correct result or else trap. This is th...

  Efficiency of code execution

If you want to optimize your program codes, you need to find their Hotspot, i.e, the codes which are executed most frequently. If you can optimize this portion of codes a bit, you may gain much improvement of your code efficiency. Here I give you three examples about efficiency of code execution.1. PHP's Getter and Setter (From Reddit)This example a quite simple, you can skip it if you want.Consider the code below, we can find it's slower when we use Getter/Setter method to read a member variabl...
