What to look for in code review

From the "Code Review Best Practices" post from Trisha Gee

What to look for section from slide:

- Fit with the overall architecture
- SOLID principles, Domain Driven Design, Design Patterns or other paradigms of choice
- New code follows team’s current practices
- Code is in the right place
- Code reuse
- Over-engineering
- Readable code and tests
- Testing the right things
- Exception error messages
- Subtle bugs
- Security
- Regulatory requirements
- Performance
- Documentation and/or help files been updated
- Spelling, punctuation & grammar on user messages

How to send Android push notification locally using ADB without need network connection

Requirements:

• Device should be a rooted (simulator’s are rooted by default)
  
• adbd should be started as root. (Rub command: adb root )
  

Now, send local push message using command:

adb shell am broadcast \
  -n com.your.app/com.google.firebase.iid.FirebaseInstanceIdReceiver \
  -a "com.google.android.c2dm.intent.RECEIVE" \
  --es "extra1" "65" \
  --es "guid" "1f400184-9215-479c-b19a-a9cd9a1d9dc9" \
  --es "extra3" "VALUE" \
  --es "extra4" "'Long string with spaces'"

What’s happening?

• Simply, using adb we are broadcasting message with parameters.
  
• adb shell am broadcast command that broadcasts.
  
• -n parameter for define component (see IntentSpec@ADB Documentation)
  
• We are broadcasting for com.google.firebase.iid.FirebaseInstanceIdReceiver, because we are using Firebase Messaging Service
  
• We are sending action -a com.google.android.c2dm.intent.RECEIVE because FirebaseInstanceIdReceiver defines this in AndroidManifest.xml file.
  
  • Also, this is why we need to be root. This action requires Signature level permission.
    
• We are adding extras with --es parameter.
  

Now, we can get data in onMessageReceived under the FirebaseMessagingService. When user taps notification remoteMessage.getData().get("extra1") should be return "65".

aws CodeCommit The requested URL returned error: 403 with Apple-Git

If you faced with this problem, probably you are using codecommit over https with apple-git.

This problem occurs because of Apple-Git caches credentials inside to the keychain. AWS CLI generates new password everytime via secret and timestamp, so it changes everytime based on time.

To achive problem, you can use nicc777's script https://github.com/nicc777/macaws-codecommit-pwdel for remove cache in time interval or you can follow instructions below:

a). Go to Keychain Access, search for codecommit (or your repository name).
b). Right click on the row and select Get Info.
c). Click on Access Control and Remove git-credentials-osxkeychain from the list and save. This way Apple-Git will not try to read from the keychain.

Other solutions:
- Use another git (ex: brew install git)
- Connect codecommit through SSH
