  How the Go language improves expressiveness without sacrificing runtime performance

This week there was a discussion on the golang-nuts mailing list about an idiomatic way to update a slice of structs. For example, consider this struct representing a set of counters. type E struct { A, B, C, D int } var e = make([]E, 1000) Updating these counters may take the form for i := range e { e[i].A += 1 e[i].B += 2 e[i].C += 3 e[i].D += 4 } Which is good idiomatic Go code. It's pretty fast too BenchmarkManual 500000 ...

  Want to make your Eclipse run faster? Try this

Lots of us may find that our Eclipse takes a long time to launch, remember how many times you want to close this heavy machine and shout "F**K". Do you know why Eclipse launches slowly? Is it because we have too many plugins installed or we have created too many projects? No, it's not. Sometimes, it's because we don't have the correct configuration. So where to start? Go to eclipse.ini. First, you may want to add below line in your eclipse.ini configuration file: -Xloggc:gc.log This is to show w...

  Run code with multiple files in the same main package in GoLang

To run a GoLang program, there needs to be a main() function defined. In some cases when developing some demo program which has multiple files and just wanna put them in the same main package and this folder is not in GOPATH, how to run the program? Let's say we have following folder structure where the main() function is defined in main.go. If you just run below command, it would fail to start to run the program and gives some error if some struct is defined in other files and being used. PS D...

  Why Good Programmers Are Lazy and Dumb

I realized that, paradoxically enough, good programmers need to be both lazy and dumb. Lazy, because only lazy programmers will want to write the kind of tools that might replace them in the end. Lazy, because only a lazy programmer will avoid writing monotonous, repetitive code – thus avoiding redundancy, the enemy of software maintenance and flexible refactoring. Mostly, the tools and processes that come out of this endeavor fired by laziness will speed up the production. This ma...

  Java Doesn't Need to Be So Bad

I do a lot of Java coding and I enjoy it. I admit that there is a lot of typing, often a lot of boilerplate and getting even simple tasks done can involve too much work. Most of the tools that try to fix these problems trade one moment saved for another lost. Maven's XML based configuration file is a good example: Thank you for making my project easier to manage and I won't forget that you made me edit XML to do so. These are the things that you live with, these are the things you trade for ...

  Don't write on the whiteboard

I recently interviewed at a major technology company. I won't mention the name because, honestly, I can't remember whether I signed an NDA, much less how strong it was.I did well. Mostly because of luck. I normally step over myself when I interview. I guess I've improved over the years. Here are a few tips to ace your own interview.1. Don't write on the whiteboardWhen I interviewed at Palantir around 5 years ago, I had a lot of trouble with this. Yes, I knew next to nothing about compu...

  5 Lightweight PHP Frameworks For Creating An API

PHP is undoubtedly one of the most popular programming languages that offer a wide range of lightweight frameworks for building basic websites to REST APIs. These frameworks are powerful tools that have the potential to enhance productivity in order to deliver faster results without getting distracted from the best practices of development. Developing REST APIs with plain PHP is a tedious and time-consuming process. In order to sort this out, you only need to hire php developers who have a niche...

  Why Windows?

Since the latest episodes of both Bent and Throw it Against the Wall have seen me mention Windows Phone 7, I think it’s about time I talk about why I like it. I know there’s a lot of scepticism surrounding it. And why not? Most people I know who were considering jumping the Microsoft ship did so in the dark days of Vista, so that’s their last experience with Windows. Anyone who saw their parents working on a Treo back in the nascent days of the Blackberry know the slop...

  How To Find Link Prospects Without Using Google

I’m obsessed with Google. (I mean, you kind of have to be if you’re in this industry.) But sometimes, you need a break from the hand that feeds. There’s no denying the power of advanced search queries, but you’d be surprised how many other and different prospects you can find without using the search engine at all. Curated Lists OK, I lied. You do have to use Google for this, but not nearly in the capacity you would with normal searches. With lists, you have less ...
