Welcome. Dedoimedo is a website dedicated to technology and software education, science, art, and (dark)
humor. Its mission:
to seek out new life and new civilizations to provide most detailed and accurate guides and
articles you will find on the Web, on a wide range of topics, including operating systems, application
reviews, security, and more. Over the past 15 years of its existence, Dedoimedo has attracted hundreds of
thousands of followers, received several software nominations and awards, and been quoted in numerous
respectable publications, including books and patents.
Dedoimedo mostly focuses on open-source technologies and Linux, but in its 2,500-article strong portfolio, you will also find valuable information on Windows, virtualization, cloud, hardware, and other topics. Step by step, laced with humor and wit. There's something for everyone, from newbies to experts.
But that's not all. Dedoimedo also covers computer games, car reviews, 3D art, popular physics, and life philosophy. Hopefully you'll learn something new. Enjoy your stay.
Back in 2006, I created Dedoimedo for two primary reasons: 1) I was curious and I wanted to learn about Web technologies 2) I was not happy with the quality of existing technical guides and tutorials available online. The all-too pervasive "all you need to do" clause in many an article left me wanting, so I decided to start writing about my software escapades, making sure that anyone who reads my tutorials will never be left with any gaps or questions.
I have used computers extensively for the last two and a half decades and have often had to solve difficult problems without instant, easy solutions. And so, I wish to make YOUR journey easier and more pleasant. My goal is to provide computer users worldwide with high-quality education and solutions to their problems, in the best fashion possible.
To that end, every single topic presented on Dedoimedo is explained to the latest detail, accompanied by multiple screenshots and examples. I never miss a step and I never assume! Everything you read has been thoroughly tested and proven to work in real, production setups.
This hobby soon became a serious effort, and Dedoimedo reached the 1,000,000 monthly pageview mark in 2012. Dedoimedo has also been nominated for the best FOSS advocate/evangelist by FOSS Force and Linux Journal in 2013, and awarded the best software blog by Rocky Bytes in 2015. Going strong ever since.
Dedoimedo is owned and run by Igor Ljubuncic: former physicist, contemporary IT nerd, fantasy & sci-fi book author, and persona extraordinaire. All in one that is.
In more detail, if you are interested:
Igor Ljubuncic is a physicist by vocation and a Linux geek by profession. Igor comes with many years of experience in the hi-tech industry, including medical, high-performance computing, data center, cloud, and hosting fields, with emphasis on complex problem solving and the scientific method. To date, Igor’s portfolio includes 15 patents, 18 books, several open-source projects, numerous articles published in leading journals and magazines, and presentations at prestigious international conferences like LinuxCon, CloudOpen, OpenStack days, IEEE events, and others.
I am currently working in a software company as a Developer Advocate, after a stint as a freelance strategy and business consultant. Throughout 2015-2016, I was a Principal Engineer with a cloud technology company. In the period between 2008 and 2015, I worked as an Operating Systems Architect with an engineering computing team for one the largest IT companies in the world, developing new, innovative solutions for high-performance computing environments. From 2004 until 2008, I used to earn my bread working as a physicist in the medical imaging industry. My work expertise focused on problem solving and algorithm development. Before that, I worked in education for a while, including managing a team of science tutors. I'm certified in several major engineering methodologies, including MEDIC Six Sigma Green Belt, Design of Experiment, and Statistical Engineering.
I have fifteen patents registered and granted with the US PTO, some of which are also registered in other jurisdictions, including but not limited to: Web/HTML language assignment, checkpointing technologies, data center power management, scheduling, self-healing systems, data center security, autonomous cars safety, IVI systems & digital signage, online shopping & emotions, mobile devices & radiation, mobile devices & audio, flexible displays, drones, and a few others. You can read about these in detail on the US PTO portal or one of the reference sites.
I have published a total of eighteen books since 2011. My portfolio spans four technical works, nine novels, and five anthologies, including a short story, The Girl with the Flaxen Hair, which was nominated for the 2014 Sidewise Awards for Alternate History!

I currently have at least more six books (and possibly several more anthologies) planned for publication in the next five years.
The IT-related works include: 1) a thorough guide on how to setup the Apache web server 2) a book on kernel crash analysis; invaluable for any large, enterprise deployment running Linux 3) a comprehensive book on problem solving; the sum of my work experience, with immense volume of data and examples from large, mission-critical environments and strong focus on statistical engineering and the scientific method 4) a system administration ethics book, a highly important guide for how to manage the modern cyber world challenges.

In a personal capacity, my short story The Girl with the Flaxen Hair, featured in the WWI anthology, has been nominated for the 2014 Sidewise Awards for Alternate History.
Over the past decade and a half, I have been certified in several engineering methodologies, including MEDIC Six Sigma Green Belt, Design of Experiment, and Statistical Engineering, and on the Information Technology side: Linux System Administrator, LPIC-1, GIAC GSEC Silver, CCHD, and CCHA. I also studied for several cloud architecture exams but ultimately chose not to undertake them, as I became more senior and hands off in my career.
I began my digital life with Commodore 64 and Spectrum ZX80 as a child gamer. Next came the XT and then a giant leap to 486. This is when I started taking interest in computers on a deeper level, with innocent hacking pranks in DOS. After that, I studied Pascal in high school for three years. My university put me through a semester course of C language. Skillz that killz.
I have used Linux in personal and professional capacity since 2004. Most of my work experience, as summarized in my book on problem solving, covers major projects and initiatives in a huge, global HPC environment (with high 10,000s of servers), with focus on kernel optimization, kernel crash analysis, automation, shared filesystems, checkpoint & restore, control groups, rebootless patching, and other technologies and systems. Some of this experience is reflected in the papers, presentations and patents mentioned earlier.
Virtualization & Cloud Computing
I have a broad practical experience and knowledge of most enterprise virtualization technology, and some familiarity with cloud technologies (although if you've seen one, you've seen them all). I have used and explored solutions that touched VMware, VirtualBox, Xen, KVM, Parallels, Linux Containers (LXC), Docker, Hadoop, Amazon Web Services, and others.
I have been a "heavy" Windows user since about Windows 3.1, with deep troubleshooting skills and knowledge, including BSOD analysis, WMIC, group policies, and more. In a personal capacity, I am most proud of saving someone's entire PhD thesis, worth four years of work - and no, no backup - from total ruin.
