DaisyDisk 4.2 Cracked for Mac

Image
DaisyDisk allows you to visualize your disk usage and free up disk space by quickly finding and deleting big unused files. The program scans your disk and displays its content as a sector diagram where the biggest files and folders at once become obvious. To drill down to a folder, just click on a segment. To bubble up, click in the center. Move the mouse over the diagram and see the name and path of each file, and enclosed files (if any).

How to install Oracle 11g XE in MacOS

This project enables you to install Oracle 11g XE in a virtual machine running Ubuntu 12.04, using  Vagrant  and  Puppet . Link: https://github.com/hilverd/vagrant-ubuntu-oracle-xe/tree/master Video:  https://asciinema.org/a/8438 Acknowledgements This project was created based on the information in  Installing Oracle 11g R2 Express Edition on Ubuntu 64-bit  by Manish Raj, and the GitHub repository  vagrant-oracle-xe  by Stefan Glase. The former explains how to install Oracle XE 11g on Ubuntu 12.04, without explicitly providing a Vagrant or provisioner configuration.

The host machine probably needs at least 4 GB of RAM (I have only tested 8 GB of RAM). As Oracle 11g XE is only available for 64-bit machines at the moment, the host machine needs to have a 64-bit architecture. You may need to  enable vi...
