How to Secure Erase Free Space on Mac Drives with OS X El Capitan

by Admin

Many Mac users running a modern version of OS X El Capitan have noticed the Secure Erase Free Space feature has gone missing from Disk Utility. What the “Erase Free Space” feature did (and still does in prior versions of Mac OS X) was overwrite the free space on a drive to prevent file recovery, adding a layer of security and privacy to file removal, much in the way that Secure Empty Trash performed a similar function of overwriting data after removal.

Stop Opera’s New VPN from Leaking Your IP Address

by Admin

Last week, Opera added a VPN to the dev version of its browser, which was certainly good news. The bad news is that unlike the more robust VPNs it tries to replace, it leaks data that should be encrypted all over the place, namely your private IP address. Here’s how to fix it.

10 Easy Ways to Restore Your Linux System

by Admin

Reverting your operating system to a previous state without consequences sounds almost like magic. You can quickly return to your work as if nothing happened, even when you don’t know what caused the problem. That’s why the System Restore feature is among the top things ex-Windows users want from Linux. Some go as far as proclaiming that Linux will never be as good as Windows because it lacks System Restore.

(Or as good as OS X because it lacks an equivalent to Time Machine, which was around long before Windows added System Restore.)

Those users should read the manual, or even better, this article, because today we’ll present the tools that bring System Restore functionality to Linux. True, they’re not always available by default, but neither is System Restore in Windows 10. You could also argue that they don’t behave exactly the same as their Windows counterpart, but then again, the way System Restore works changed between Windows versions.

However, for whatever reason you might want to remain anonymous or unidentifiable (if you may) on the net, in this article is our pick of tools that will help you achieve your purpose effectively without the risks that usually come with surfing the Internet unprotected.
