These reCAPTCHAs where not meant to be read by humans

How to dual-boot Kali Linux 1.0.9 and Windows 7/8 on a PC with UEFI firmware

How to dual-boot Kali Linux 1.0.9 and Windows 7/8 on a PC with UEFI firmware

The last dual-boot tutorial on Kali Linux I wrote was back in March 2013 (see Dual-boot Windows 7 and Kali Linux), and that was on a computer with Legacy BIOS. That means it’s not a very useful guide if you wish to dual-boot a recent edition of Kali Linux and Windows 7 or Windows 8 on a computer with UEFI […]

Wget and the user agent option

Wget is a command-line utility for downloading files. The official description on its man page on my Linux distribution says that it is “free utility for non-interactive download of files from the Web”, and that it “supports HTTP, HTTPS, and FTP protocols, as well as retrieval through HTTP proxies.” It especially comes in handy when I need to download an […]

How to dual-boot Windows 8 and Fedora 21 on a PC with UEFI firmware

So Fedora 21 has been released, and my attempt to upgrade my main computer from Fedora 20 to Fedora 21 KDE failed. Since the cause is not something I could fix in a snap, I opted instead to set up a dual-boot system between an installation of Windows 8 that’s on a 500 GB hard drive and Fedora 21 KDE […]

How to upgrade Ubuntu 14.10 kernel to version 3.17.1

Upgrading a distribution’s kernel is something I tend to shy away from. There was a time, though, when recompiling the Linux kernel was fun. But that was years ago. Now, I just use the version that’s installed and let the system take care of upgrading to the latest stable version. But after I found out that my Linux Mint-powered-laptop, which […]
