This weekend i’ve been playing with my i3 desktop settings. Here are the result

Made with:

• Window Manager: i3
• Background: Ori
• Color Scheme: Nord
• Polybar: adi1090x/polybar-themes-8
• Conky: conky

If you are in the need of converting your custom intellij live tempate, you can use this method to transform it.

Locate the template file

The first thing you need to is is to locate the template file. You can find it inside the intellij settings directory which is vary per operating system. See this documentation to locate it.

For example for my golang templte in linux, I find it under

It’s all started when my colleague asked this question.

I have more than 11 years of experience in software development. I involved in designing, architect, and implementing high throughput systems serving traffic for one of the top popular sites in the Netherlands.

I’m so excited with the new release of golang. One particular feature is now very easy to build for multiple architecture. If you seen my other posts, I also like to tinker with my raspberry-pi. On my previous project I use either ruby or python for building some stuff. One annoying thing is dependency, setup and compilation is usually quite slow. Would be cool if I could just create some stuff in desktop and just scp the binary to pi and everything should work!

As a part of scrum teams, every day I need to give updates to my team via Google Hangout. We have a team here in the Netherlands and also in Indonesia. Some times I am in the same room as a colleague of mine. This sometimes quite annoying because I can hear my self (with a delay) from his mic. This somehow messed up my brain. Google Hangout already has a ‘auto adjust mic volume’ that is really great which cancel the noise. But we still have a problem and end-up muting each other when we want to talk.

I’ve been involved with a iOS project this past week. I’m adding functionalities to the CommonSense iOS library. One of the most annoying thing is that it took about 2 minute to load the project. This is only happened in the unstable branch. The master branch seems to be working fine. So I knew that somewhere there is a commit when this starts happening.

Sometimes it’s really hard to test functionality that involve with system time. Especially when we want to test the function with a specific time. For example testing whether today is end of month or test 2 different behavior at a different time

Below we look into different ways we can mock or stub the time. Each with it’s own advantages and disadvantages.

Passing the time instance

 1func CheckEndOfMonth(now time.Time) {
 2    // business process
 3}
 4
 5func main() {
 6	CheckEndOfMonth(time.Now())
 7}
 8
 9// for test
10func TestCheckEndOfMonth(t *testing.T) {
11	CheckEndOfMonth(time.Date(2019, 1, 1, 0, 0, 0, 0, time.UTC))
12}

You are probably familiar with above images. Some random friend sent you an email which you can instantly recognize as a spam because it only contains one link. Couple days ago I receive this email which is not the first time for me. But this time it was different. It actually came from my own Yahoo! account which I never use since more that one year ago.

Berksfhel is cookbook dependency for chef. If you are familiar with ruby / python, think of it as a Bundler or virtual environment for chef

I faced this core dump error while doing berks upload. That command will actualy push some cookbook to a chef server.
