Cloud computing has made massive computing resources to be available instantly to users with a single command. The always available, on-demand computing infrastructure comes specially handy for developers as it allows them to create and destroy development instances easily. One of the major benefit of cloud computing is you only pay for what you use, so when you are not working on a cloud-computing instance it can be powered-down and no computing cost will be charged. One drawback/annoyance of using this strategy is that the "publicly addressable" IP address will change with every reboot, to get past this we will show you how to use an automatically updated free dynamic dns system so you don't get bothered about the changing IP address anymore.

Apple iOS uses a small list of "random" words to generate default passwords for the "personal hotspot" Wifi sharing option, and researches have now exploited this security oversight to crack these passwords in less then 50 seconds for majority of them. This not only allows the hacker to use your internet connection but once connected on the same network the hacker can also launch man-in-the-middle attacks for gaining access to your Apple device and the data traveling through the connection. The team also released the source-code for "iOS Hotspot Cracker" app written in Apple's Xcode programming environment for everyone to download.

File-format incompatibility between Apple Mac OS and Microsoft Windows operating-systems is something every user faces utilizing both operating-systems. One such incompatibility is the disk-image format used by both operating-systems, while Apple Mac OS uses .CDR format Microsoft Windows utilizes the international disk-imaging standard .ISO, so you would need something to convert .CDR to .ISO file-format and vice-versa to use them under rival operating-systems. Luckily, the only difference between two is the file-extension, and all one needs to do is to change the .ISO/.CDR extension to make them work interchangeably without any real file-format conversion. We can also use this fact to make perfectly bootable USB disks from .CDR files from Windows and Linux using existing tools allowing cloning of .ISO format to USB.
