One day back in 2007 I was dribbling down some notes about programming languages and compilers with a special focus on the use of C, C++ and Ada. These are some of my dribbles. https://unixdigest.com/articles/programming-in-c-cpp-and-ada.html
EncFS provides an encrypted filesystem in user-space. It runs without any special permissions and uses the FUSE library and Linux kernel module to provide the filesystem interface. https://unixdigest.com/tutorials/using-encfs-to-encrypt-some-of-your-files.html
Currently I am using Mercurial revision control system to version control my programming files and written articles etc. Other important files I manually tar up and encrypt and upload to my backup server using sftp from OpenSSH. I decided that it was time to take a look at a better way to deal with my personal backups. https://unixdigest.com/tutorials/choosing-a-new-backup-solution-duplicity-rdiff-backup-or-rsnapshot.html
Ubuntu GNU/Linux has grown to become the most famous Linux distribution in the world. It is the Linux distribution on DistroWatch that currently has the greatest hit rate, and even though it is based completely upon Debian GNU/Linux, it has almost twice as many hits. This articles explains what Ubuntu is and what relation it has got with Debian. https://unixdigest.com/articles/ubuntu-as-in-debian.html
I have been using GNU/Linux, FreeBSD and OpenBSD exclusively since about 1999 and I spend time with Linux and BSD every single day both at home and at work. From time to time I still like to test some of the other Linux distributions to see whats new in the world of Linux. This time I decided to test Arch Linux. Arch Linux is really great, but it is not for people wanting a stable desktop or server system. https://unixdigest.com/articles/trying-out-arch-linux.html
PHP web applications are one of the most commonly attacked pieces of software on the Internet today. Anyone who has looked at their web server logs can attest to the frequency of probes for vulnerable PHP applications.
