Running Docker on Linux Mint

Docker doesn't come natively installed on Linux Mint. To be able to run it you will need apparmor and cgroup-lite packages. Follow the steps below to get it working:
  • Add repository to APT sources
    • sudo echo deb https://get.docker.com/ubuntu docker main > /etc/apt/sources.list.d/docker.list
  • Import repository keys
    • sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9
  • Install Docker 
    • sudo apt-get update
    • sudo apt-get install -y docker.io cgroup-lite apparmor
  •  Check if Docker daemon is running 
    • ps aux | grep docker
  • If docker daemon is not running, try the following command:
    • sudo service docker start
  • Check if docker.sock exists. This file needs to be owned by docker group to be able to connect to it without root permissions
    •  ls -al /var/run/docker.*
  • Check if user is part of docker group  
    • id -a
      • If user is not in the docker group you can add them using this command: sudo usermod -a -G docker $USER

Geospatial queries in MongoDB - Part 2 : {"err": "location object expected, location array not in correct format" "code": 16804}

In my last post we saw we had to create a geospatial index on the " pos " field as follows: > db.foodtrucks.ensureIndex({pos:"2d"}) However, when executing the command above we get the following error:   > db.foodtrucks.ensureIndex({pos:"2d"}) {     "createdCollectionAutomatically" : false,     "numIndexesBefore" : 3,     "ok" : 0,     "errmsg" : "location object expected, location array not in correct format",     "code" : 16804 } After some further investigation I realized that we had some documents which didn't had any latitude/longitude information. Due to this some of the documents looked like this: {     "_id" : ObjectId("53d07bf1e3e11dacc21056a8") ,     "locationid" : 437222 ,     "Applicant" : "Natan's Catering" ,     "FacilityType" : "Truck" ,     "cnn" : 188101 ,     "Locatio...

Remove and ignore files like .DS_Store, .classpath so that it doesn't get added to your github repo

When promoting code on github it is usually a good idea not to promote files like .DS_Store. .classpath etc. To accomplish this you can include a .gitignore file in your first commit . Git uses it to determine which files and directories to ignore, before you make a commit. Here is what my .gitignore looks like: /.buildpath /build/ */archive/ # Compiled source # ################### *.com *.class *.dll *.exe *.o *.so   .project .settings .classpath # Packages # ############ # it's better to unpack these files and commit the raw source # git has its own built in compression methods *.7z *.dmg *.gz *.iso *.jar *.rar *.tar *.zip # Logs and databases # ###################### *.log *.sql *.sqlite # OS generated files # ###################### .DS_Store .DS_Store? ._* .Spotlight-V100 .Trashes ehthumbs.db Thumbs.db Icon?     Alternatively, you can create a global .gitignor...
