  Why Objective-C is Hard

As an active member of "The Internet" and vocal Objective-C coder, I get a lot of questions surrounding the language. They're often framed around thinking about learning the language or trying to write an app, but they also usually involve a phrase like "Objective-C looks really hard" or "what are all those minus signs about?" Both of these are pretty good questions, and I'd like to address why someone might be more hesitant to jump into iOS or OS X development compared to, say, Ruby or J...

Can you tell us a bit about the nature of the projects in which you took part at that time?Rogers Cadenhead: I've been a Java programmer since the language was launched by Sun Microsystems in 1995. I was doing website develop...

  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...

  Thoughts on Python 3

I spent the last couple of days thinking about Python 3's current state a lot. While it might not appear to be the case, I do love Python as a language and especially the direction it's heading in. Python has been not only part of my life for the last couple of five years, it has been the largest part by far. Let there be a warning upfront: this is a very personal post. I counted a hundred instances of a certain capital letter in this text. That's because I am very grateful for all the opport...

  Stop Making Apps

There are a bunch of iPhone apps I own though I have no clue what they do. These apps include but aren’t limited to; FLUD, Apptitude, Cartoonatic, Can’t Wait!, Punch, Pah, Prize Claw, Traveler, Concur, Jajah, Fast Customer, Pimple Popper and many more whose names I can’t even remember.Occupying my valuable homescreen real estate are also a bunch of apps whose purpose I remember only because they were built by people I know or am friends with, but that I sadly never use. And ...

  Why developer-friendliness is central to API design

Today, APIs play a bigger role in software development than ever before. The evolution of computing has been dominated by ever-increasing levels of abstraction; the use of higher-level languages, of course, but also the development of platforms, libraries, and frameworks. Professor Douglass C. Smith claims the progression of this second category far outpaced the development of programming languages.  Developers are also noticing that difficulty has shifted from designing algorithms a...

  Our Go Cache Library Choices

In Build a Go KV Cache from Scratch in 20 minutes, I walked you through what matters when writing a local cache, and eventually implemented one, whose performance was beaten badly by that of the popular go-cache on Github though. However, the bright side is that we can learn a lot from those excellent Github Go cache products, studying their features, applicable scenarios, and implementations, and extracting what we need. In this article, I will mainly analyze and compare the four...

  Mock Solutions for GoLang Unit Test

In Go development, Unit Test is inevitable. And it is essential to use Mock when writing Unit Tests. Mock can help test isolate the business logic it depends on, enabling it to compile, link, and run independently. Mock needs Stub. Stub function replaces the real business logic function, returns the required result, and assists the test. I involved the related test code for Controllers while writing Kubernetes Operator recently, and there would be mocks for GRPC and HT...

  Valid JavaScript variable names

Did you know var π = Math.PI; is syntactically valid JavaScript? I thought this was pretty cool, so I decided to look into which Unicode glyphs are allowed in JavaScript variable names, or identifiers as the ECMAScript specification calls them. Reserved words The ECMAScript 5.1 spec says: An Identifier is an IdentifierName that is not a ReservedWord. The spec describes four groups of reserved words: keywords, future reserved words, null literals and boolean lite...

  Why I Still Use Emacs

At school, I’m known as the Emacs guy; when people have questions about configuring Emacs or making it work a certain way, they often come and ask me. Sometimes, some people ask me why use Emacs at all? Isn’t it a really old editor and aren’t Eclipse or Visual Studio much better? I mean, they don’t have weird key bindings and have intellisense, that’s surely better for a programmer, right? I will attempt in this post to explain some of the reasons why I still c...
