Our contributions are visualized as “turf pixels” on the profile page in GitHub. Previously, a new web service, Pixela was released. We can get turf like graphs via these APIs.

I visualized my contributions history of GitHub Wiki with Pixela graph.

Why did I try it?

This is a note about settings to use git push with 2-step verification GitHub account without using Terminal.
In this article, I used GitHub Desktop (as a GitHub client) and Atom (as a text editor) instead of typing on Terminal. (I guess that you can replicate those steps by other applications which is familiar with you.)

This article is for non-engineers who need to use Git reluctantly, so I write only the minimum steps.

  2. create .netrc file on your home directory

It’s a memo for myself and I write about how to uninstall updates of Google Play Services (in other words, how to replace Play services with the factory version).

Google Play Services provides some core feature for Android apps and so that we should care users who use older version. If we want to check behaviors of our products with older Play service, we should try after uninstalling updates of it.

It is assumed that some errors occur after uninstalling that. (ex. logged out any application, disabled to sync data, or so.)

  1. open “Settings” > “Apps” > “Google Play services”

Hi, Software Engineers and QA Staffs. I worked to test some feature of our product which use Bluetooth connection last week. In my work, I had to know my Bluetooth headsets and speakers support which profiles. So I‘ll write how to know that with MacOS.

About Bluetooth Profiles

If you could understand what “support which profiles” means, you would not need to read this section.

I dare to say roughly, each Bluetooth devices support some ways to access or control paired devices. …

Hi, application developers and QA staffs.
I’m belong to an Android application development team as a part-time QA staff. Today, I’ll tell you 4 things I actually asked developers of my team.

- who can make communications in Japanese and English
- who can explain bugs with sentences
Unexpectedly, I have also:
- a little old knowledge of Android application development
- the experience of team development on agile process with Trello, Slack and GitHub.

Hi, Android App testers. It’s a memo about when I use ADB as a App tester (instead of as a developer).

Install Android Studio, At First

Some years ago, we could install “Android SDK” without any IDE. But now, installing “Android Studio” is easier than installing SDK alone.

Use ADB on “Terminal”

If you use ADB on “Terminal”, you should form the path to the platform-tools in Android SDK. Command:

export PATH=$PATH:/Users/${user_name}/Library/Android/sdk/platform-tools

Use ADB on “Terminal on Android Studio”

“Android Studio” has the Terminal pane (default viewing the project home directory) and you can use it (instead of macOS Terminal). But you can’t use ADB on it initially, so you should form the path as said above.
