Install ubuntu on lenovo yoga 900


Setting up lenovo yoga 900 with ubuntu is not straight forward. 

Get into bios by pressing the tiny circular button on the right side of the laptop with a toothpick when the computer is off.
  1. Enable back update in bios
  2. Boot to windows, dowload linux-specific bios update from lenovo, install it and follow instructions.
  3. Change configuration in bios under "configuration" from RAID to ACHI.
  4. Boot from your ubuntu usb-stick, pressing fn-f12 during restart.  
Happy linuxing.

Android installation issue, errorcode -505

Recently I have dealt with some installation-issues for an android app:

1st failure, duplicate permission

11-26 17:39:40.730 10166-10166/? E/Finsky: [1] PackageInstallerImpl$2.onReceive: Error -505 while installing com.something.else: INSTALL_FAILED_DUPLICATE_PERMISSION: Package com.something.else attempting to redeclare permission com.something.else.permission.C2D_MESSAGE already owned by com.something.else
11-26 17:39:40.730 10166-10166/? W/Finsky: [1] InstallerTask$3.installFailed: Install failure of com.something.else: -505 null
: This is probably due to an install of the same application on a different profile on your phone. Either make the user uninstall the app for ALL profiles on the phone or rename your C2D permission. This can be done without breaking the gcm-funcitonality by adding a middle-fix between your application-id and C2D_MESSAGE. In my case I renamed "com.something.else.permission.C2D_MESSAGE" to "com.something.else.permission.e.C2D_MESSAGE"

2nd failure, gms bug

 W/PackageManager(1007):  com.android.server.pm.PackageManagerException: Can't install because provider name com.google.android.gms.measurement.google_measurement_service (in package com.something.else) is already used by com.quoord.tapatalkpro.activity
: add applicationId to the main flavour of your build. Even if it is defined in AndroidManifest.xml, other libraries just reads the build.gradle file. If it is empty it will clash with other applications doing the same thing.

3rd failure, same name as provider in other(random) app

INSTALL_FAILED_CONFLICTING_PROVIDER.
: change authorities of your provider since it has the same authority as a random other app you have installed. E.g. add ${applicationId} as a prefix to your authorities where you declare your provider in the manifest like this:
provider
            android:name=".something.CommonManager"
            android:authorities="${applicationId}.commonmanager"
            android:readPermission=".commonmanager.read"
            android:writePermission=".commonmanager.write" /

assertj java7

Do NOT use assertj v 3.x if you are developing for java 7 or android. You will end up with the error
error: cannot access CompletableFuture
Downgrade to assertj 2.x to fix it if you are using jdk7, use version 1.x if you are developing for android.

Connecting to redis on heroku with golang

I have an app on heroku using the redis-addon provided by heroku ("Redis Heroku"). To connect to this instance using go-redis, I have found this to be a working solution:
  • The redis url is provided as an environment variable, REDIS_URL
  • To use redis from golang, I use redis-go.  I install this library by typing "go get github.com/gopkg.in/redis.v3"
  • Parse the url and extract the user before connecting(unless, you might end up with the error "dial tcp: too many colons in address redis://...")
