Bye Slack, Meet Teams

I have been a long time user for Slack. The thing that I don’t like Slack is getting heavier and getting slower.

Today I read a new article saying Microsoft Teams got over 2M daily active users in their Teams service. I think that they bundled it as a part of Microsoft Office 365 and it could be a booster to acquire enterprise users.

It is interesting to see what Microsoft has been doing in the recent years. Then I feel that I become a fan of Microsoft. So next time if I have a chance to build a new team I would like to try Microsoft solution for our teams.

Git ignore vs Git exclude

If you are a developer you might have used git to manage your source repository. Then you might use .gitignore file to exclude files or folders that you don’t want to sync with your remote repository.

.gitignore

If you specifies files or folders in .gitignore file, you can exclude files or folders messed up by an unexpected situation. Because it syncs with your remote repository which means all your team members share this configuration for a project.

exclude

git ls-files --others --exclude-from=.git/info/exclude

When I work on a React Native project then I need to be careful not to affect Android sources. In this case exclude file could be a solution for you. The scope of exclude file is for your machine which means that you exclude folders or files in your machine not to sync with the remote repositories.

React Native - launch an app on iOS device and quit immediately without errors

Recently I have got an error(?) when I launched a React native application on iOS device for testing. Then it caused a strange symptom like below.

• No loading from React native testing server
• The app launched and quit automatically without errors in the Xcode console

So I take a time to figure out. Then I just thought about looking into Device crash log which you can check in the Xcode Device and Simulators menu. Then I found that there was a library linker error and it caused the crash.
After I fix the library link in Xcode and it works fine. I hope it helps someone who faced this kind of error.

Bitbucket authentication error, Invalid username and password

Today I have faced an issue that I couldn’t push/pull to(from) Bitbucket repository. I used Sourcetree and I got failed to do it with the error below.

Invalid username and password 

I tried to change my password in Bitbucket and it didn’t work. Also, I tried to reset Bitbucket related keychain in mac os. It still didn’t work.

Remove all your keys in Keychain Access

Most answers in the web suggests you to remove all your keys in Keychain Access app on your Mac. I did it, too. Before you take it below try this at the first.

Using SSH in Shell

I recreated a private/public key pair using below.

ssh-keygen -t ed25519 -C "email@example.com"

Then I added the public key to Bitbucket account. Then I tried to test it using SSH-Agent.

ssh -T git@bitbucket.org

Then I went back to Sourcetree and tried it again. It finally worked. It was a strange that I didn’t get any issue on Github and Gitlab. I think that the experience of Bitbucket is getting more complicated than other Git cloud services.
