How to Resign an iOS App

Let's say you receive an app (e.g. MyApp.ipa) from another developer, and you want to be able to install and run it on your devices (by using ideviceinstaller, for example).

Or your certificates and provision profiles have expired and you want to provide a new build to your clients without having to make a new build on the latest XCode or iOS SDK.

Prepare New Signing Assets

The first step is to attain a Provisioning Profile which includes all of the devices you wish to install and run on. Ensure that the profile contains a certificate that you have installed in your Keychain Access (e.g. iPhone Developer: Some Body (XXXXXXXXXX) ). Download the profile (MyProfile.mobileprovision) so you can replace the profile embedded in the app.

Maintaining even a small mongodb application in production requires regular backups of remotely stored data. MongoDB gives you three ways to acomplish it. In this post I'm using monogodump command for creating a backup and mongorestore for recreating the data. The purpose of this writing is to provide a simple way of periodic database dumps from a remote server to a Dropbox cloud storage.

Remember that for using mongodump you have to have a mongod process running.

Dumping a database

Suppose that you want make a backup of your books database.

To create a dump use mongodump -d books -o which will result in a book folder containing bson files with all collections.
